Specification of Letters Patent.

Patented Feb. 8, 1916.

Application filed August 8, 1914. Serial No. 855,744.

' and described is particularlyintended for use as a shaving brush, though suitable for other uses as well, and comprises improvements over the brushes illustrated and described in my Patents Nos. 904,190, dated November 17, 1908, 1,006,641, dated October at, 1911, and 1,067,596, dated July 15, 1913, and in my applications for Letters Patent 'Sr. Nos. 629,647, filed May 26, 1911 and and 762,847 filed April 22, 1913.

My invention comprises particularly an improved construction of operating means for such brushes, whereby backward rotation of the feed screw is prevented, and

whereby an indication is given to the oper:

' ator of the amount of soap or the like that he is expelling; also in an improved construction of the connection between the operating hand piece and the feed screw.

The objects of my invention are to im- I prove and simplify fountain brushes, and

particularly to provide improved means for preventing backward rotation of the operating hand piece ofsuch brushes, and to provide an improved connection between such operating hand piece and the feed screw.

'I will now proceed to describe my invention with reference to the accompanying drawings,and will then point out the novel features in claims.

In said drawings: Figure 1 shows an elevation of one form of the brush provided with a sliding cover. Fig. 2 is a similar view, except that the sliding cover'and the top thereof are shown in longitudinal section. Fig. 3 is a. side view of the brush, showing the sliding cover moved downover the handle, to expose the bristle tuft for use. Fig. 4 shows a side elevation of a plain Fig. 7 is a perspective elevation of the end cap of the handle, a portion of the side of the. end cap being broken away. Fig. 8 shows,'on a smaller scale than Fig. 5, a central vertical section of the reservoir, de-

tached from the brush, a portion of the delivery tube of that reservoir being shown in elevation, and 'theprotecting cap on the top of that delivery tube being shown in section. Fig. 9 is. a fragmentary vertical section of the lowerportion of the delivery tube, as the same is before it is placed upon the reservoir.

In the drawings, 1 designates the bristle tuft, 2 designates a-screw threaded ferrule constituting the bristle holder, 3 designates.

the main portionof'the hollow handle, and

4 designates a screw-threaded ferrule fitting into the upper end of the handle 3 and into which the bristle holder 2 screws.'

5 designates a central tube secured to, and in effect forming a part of, the bristle holder 2, through which tube the flexible feed tube 6 of the brush passes into the bristle tuft.

7 designates-a removable reservoir within connected, as hereinafter described, so as to be in effect a part of that reservoir.

the handle, and to which the feed tube 6 is Sdesignates an end cap for the handle,

screw connected to the main portion 3 of the handle, and serving to hold the reservoir 7 in place, and 9 designates a hand piece rotatably mount-ed upon this end cap 8, and to which is connected the feed screw 10 extending up into the interior of the reservoir 7 and having mounted upon it a piston 11 adapted to force the plastic contents of the reservoir into' the feed tube 6.

12 (Figs. -1, 2, 3 and 5) designates a sliding or telescopic cover for the bristle tuft mounted to slide upon the handle 3' and provided at its upper end with a removable cap 13., To guide the cover 12 and permit it to slide over the handle 3, without marring the surface thereof, such handle 3 is provided witha spring collar 14 provided for when said bristle tuft is inclosed by the at its lower end with downwardly and outwardly projecting spring leaves 15 which, in action, bear against theinner wall of the cover 12, so centering and guiding the said cover, and which also, when the cover is in its raised position, indicated in Figs. 1, 2 and 5, bear against a hook-shaped bead 16, formed on the lower end ofthe cover, thereby arresting outward or upward movement of the cover. In other words, these spring'leaves 15 form stops for the cover. It is important that circulation of air around the bristle tuft shall be provided cover, and to that end I provide a number of side openings 17 in the cover and have also provided openings 18 (Fig. 2) in the cover cap 13, which openings 17 and 18 permit f-ree entrance of air into the handle, and free escape of air from the handle, and therefore make possible the rapid drying of the bristle tuft when wet. In order that the ends of the spring leaves 15 shall not catch in the openings 17 of the cover, the ends of said spring leaves are rounded, as indicated in Fig. 2.

The construction comprising a spring col-v lar 14 having spring leaves 15 adapted to guide the handle 3 and also to engage the bead 16 on the lower end of the cover, is claimed in my application Serial No. 629,647 filed May 26,- 1911.

'In the form of brush .shown in Fig. 4, in which 'no telescopic cover is provided, the collar 14 and spring leaves 15 are of course omitted. The piston 11 may be formed of any suitable material; for example, cork'composition or rubber composition.v It is customarily provided with a reinforcing bottom plate, 19, secured to the piston disk 11by means of points or prongs 20 cut out o-fthe material of said bottom plate 19, and pressed into the disk 11 and there clenched. The bottom plate 19 is provided with a central hole to receive the feed screw 10, this central portion of the disk 19 being provided with a rib 21' surrounding the said hole, which rib serves to thicken the plate 19 at this point, providing sufficient thickness for enough screw threads to insure suitable engagement with the screw threads of the feed screw 10. In practice, the rib naturally formed on the plate 19, in punching the central hole in said plate,is a suflicient rib.

The reservoirs 7 are customarily formed of glass; though I do not limit myself to reservoirs formed ofthis material. It is practically impossible, except at prohibitive expense, to obtain glass tubes or the like of uniform internal diameter, and which are approximately cylindrical. To obtain a tight joint between the piston 11 and the reservoir 7 (the diameters of difierent reservoirs varying somewhat as previously explained) I apply a layer 22 of some suitable plastic material (glue, gelatin, paraiiin or the like, constitutes a suitable material) to the outer side ofthe piston, and then after the piston has been'inserted in the reservoir'a'nd before the delivery tube has been applied to the reservoir, I insert a hot metal tool through the upper end of the reservoir,

rigid, forms an excellent guide for the pis ton, preventing the latter from assuming an angular position in the reservoir, and so insures that the piston shall slide freely within the reservoir. The said sealing material, so pressed against the sides of the reservoir, adheres tightly to the sides of the reservoir and thus tends to hold the 4 piston stationary when the screw 10 is inserted through the sealing layer 22, and is turned up through said piston until the end cap 8 is screwed on to the handle.

. Thereafter, this sealing layer prevents the rotation of the piston, when the screw is turned, forcing the piston to travel longitudinally through the reservoir as the same is turned; whereas, but for the friction of this sealing layer against the sides of the reservoir, the otherwise loosely fitting piston might itself turn with the screw, in which case the piston would not travel through the reservoir. While, as above stated, the sealing layer 22 adheres tightly to the sides of the reservoir, when it has cooled, nevertheless such adhesion is easily broken by an upward thrust of the piston due to rotation of the screw 10.

The piston having been placed in the reservoir 7, and the sealing layer 22 having been pressed against the sides f. the reservoir, as previously explained, the reservoir is filled with soap or other material to be contained within that reservoir, and then the base of the-feed tube (Sis applied to the upper end of the reservoir. This feed tube is customarily of elastic rubber, and so is its base portion 24. The reservoir being provided with a neck portion 25 and having beyond such neck portion an upwardly turned flange 25, the base 24 of the feed tube is readily fitted over such flange 25", as shown particularly in Fig.' 8, and then a metal disk 26, perforated centrally for the passage of the feed tube 6, is applied above the base 24 of the feed tube and its edge is also pressed or spun over the edge of the flange 25, as indicated in Fig.

y the elasticity of the material of the feed tube 6, that little or no escape of the volatile ingredients of the soap or other contents of the reservoir can take place through such slit; the two lips of the feed tube formed by the slit 27, constituting'an automatically closing mouth for the feed tube. But to guard against even such slight escape, I customarily provide the upper end of the feed tube with a protecting cover 28. This covering is usually applied by dipping the end of the feed tube into molten paraflin, gelatin, glue or the like. When the end of the tube is dipped into said material, and then withdrawn a thin film of uickly solidifying, seals the slit 27 perectly. In Fig. '8, for clearance of illustration, the thickness of thisclosure 20 is greatly exaggerated. .The sealing layer 28 is readily broken by the semi-liquid or liquid material within the reservoir when the latter is forced up through the feed tube by means of the piston 11.

To insure a tight joint between the base of the feed tube and the mouth of'the reservoir, said feed tube is provided on its upper side with a raised rib 29; (see Fig. 9).

When this feed tube has been applied to the reservoir and the metal cap 26 is applied and pressed firmly down upon the base of the feed tube,'this rib 29 is displaced inward,

by reason of the elasticity of the material of which the base of that feed tube is formed,-thus forming on the inner surface of the base of the feed tube an inwardly projecting rib 30 which presses firmly against the flaring portion of the mouth of' V the reservoir forming a tight joint.

To prevent the piston from being drawn out of the reservoir after the latter has been filled, I fit to the lower .end of the reservoir, a cap, customarily a metal cap,

- 31, having a central perforation 32, for the passage of the feed screw 10. In practice this cap 31 is cemented firmly to the reservoir 7. p

The reservoir described is in eflect a non-" refillable reservoir since, with the opening in the piston 11, sealed by the sealing layer 22, and with the discharge tube heldin' place by the metal cap 26, and with the orifice at the upper end of the discharge tube closed by the sealing layer 28, it is practically impossible to refill the reservoir when empty without leaving indication of such refilling.

In some cases, to further seal the reservoir and to provide visual indication of tampering therewith, I provide between the bottom layer of the reservoir and this cap 31, a layer 33 of frangible material (paper, for example) which is readily pierced by the feed screw 10, when the latter is inserted into the reservoir, and which, when unpierced, is readily visible through the opening 32 in the cap 31. But in general this additional layer is unnecessary, since the sealing layer 22 closes the hole in the piston, and this sealing layer '22, when unpierced, is itself visible through the opening 32 in the bottom of the cap 31. v I v The reservoir having the piston 11 provided with a sealing layer 22 and having the discharge tube 6secured to such reservoir by the metal cap 26 and having a frangible layer 33, is claimed in my application for Letters Patent Serial No. 7 62,847 filed April 22,1913.;

The feed screw 10 has. secured to it, just above the hand piece 9, a-pawl disk 34 (Fig. 6 provided with one or more spring pawls 37, customarily formed by slitting the disk partly, as indicated in Fig.6, and bend.- ing downward the ends of the spring leaves, thus'formed from the materialof the disk. These spring pawls 37 are adapted to engage corresponding recesses or apertures 38 (Fig. 7) formed in the end cap 8 of the handle of the brush, when such ends of the pawls come in registry with such aperture.

In Fig. 5, near the right of such figure, one

of such pawls 37 is shown in engagement with such an aperture 38 The said pawls,

.ward, except ashemay desire to turn it backward in order to remove the end cap 8 from the handle 3 to remove an exhausted reservoir and insert a new reservoir; for 'once the pawls 37 are ngaged withthe ard rotationrof 9 will unscrew-the end cap i2) apertures 38, further bac the hand piece V from the handle. This engagement of the pawls 37 with the recesses 38, therefore,

serves to show the user of the brush in which in the construction direction he should rotate that hand piece to feed the contents of' the. reservoir into the bristle tuft. Further, since thepawls 37 make a clicking noise as they engage theapertures 38, they serve to indicate to the user of the brush how much soaphe is expelling into the brush; for the user soon learns the relative amount of soap or other contents of the reservoir discharged into the bristle tuft by each partial rotation of the hand piece 9 represented by a click of the pawls 37.

the pawldisk 34 and the hand piece 9 being gripped tightly between flange 39 and head 40. In practice, flange 39 is first formed on the screw, by upsetting the metal of that screw at the proper point, and then the pawl disk 34, end cap 8 and end'piece' 9 are placed over the end of the screw, the pawl disk 34 resting upon the said flange 39, and the head 40 is then formed by upsetting the end portion of the metal of the screw. The hand piece 9 is centrally depressed, as indicated in Fig. 5, both in order that the head 40 of the screw may not project beyond the outer rim of the hand piece 9, and in order that the inner edge of the end cap 8 may be engaged by such centrally depressed portion of the hand piece 9, thereby centering the hand piece 9 with reference to the end cap 8, and preventing any undue looseness of the parts. It will be seen that the hand piece-9 engages the end cap 8 both at the said centrally depressed portion of the hand piece, and at the top of the rim of the hand piece. In addition, sincethe pawl disk 34 is directly above the end cap 8, and

in practical contact therewith, a very steady rotary bearing for the screw 10 is provided; which bearing is renderedvyet more steady by the pressure of the pawls 37 on the end cap 8.

What I claim is: 1. The combination with an end cap of a fountain brush, of a hand piece rotatably mounted on the outside of said end cap and having-a feed screw extending therethrough, and means arranged within said cap for permitting relative rotation of said cap and hand piece in one direction only.
