specification of Letters Patent.
Application filed July 13, 1909. Serial No. 507,295.
T o all whom t 'may concern:
y 13e it known that l, @scan NnnnsoN, a citizen of the United States, residing at McGregor, in the county oi Aitkin and tate of lt'innesota, have invented certain new and useful Improvements in Fountain laint- Brushes; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.
My invention relates to new and uset'ul iniprovenients in fountain paint brus es and my object is to provide a'brush ot this kind whereby the paint lwill be gradually lied into thebrush as the saine is being used.
A furtlu'n, object is to provide a suitable reservoir lier containing a quantity et' paint.
A further object is to provide means for directing pressure ontlie contents of the reservoir.
t'urther object is to provide in ams for disposiugl'he pressure applying device Vadjacent the upper end ot tht` reservoir.
Other objects and advantoges will be hereinafter referredA to and more particularly pointed out in the claims.
in the accompanying drawings vForming part ol` tlis application, Figure l is a central vertical seetional view through the brush. Fig. is a transverse sectional view as seen on line 2 9, Fig. 1. Fig. 3 is a similar view as seen on line 3-3, lig. l.
Referring to the drawings in which lsimilar reference numerals designate corresponding parts throughout the several views7 l indicates a reservoir which is preferably cylindrical in cross section and 2 indicates the bottom of the reservoir, while 3 indicates the covering therefor, said covering having a depending tlange il, to tit around the upper edge ot' the reservoiiz The bottoni 2 is positioned above the lower end of: the reservoir l to torni a seat 5 t'or a disk ti, while innnediately below the disk is positioned the head 7 ol the brush 8, the upper surface t) of the head being conical. The head 7 attached lo the disk (3 bv means of a bolt 10, the upper end ol said bolt having a ball head il, which tits a semi-circular seat l2 formed in the nppor surface ot' .the disk, while the lower portion ot the opaiing 123 in the disk is dared, whereby said bolt will be permitted to swing tor a. purpose to be hereinafter set forth.
The paint troni the reservoir l is conveyed tothe bristles ot' the brush 9 and in position to be spread upon an object through the me diuni ot flexible tubes ll, the upper ends of said tubes being fixed in openings 15 in the disk (S and in position to register with ports 1G in the bottom Q, said liexilole tubes being directed downwardly through the tufts of bristles forming the brush, so that the paint. will be engaged with the brush adjacent its free end.
llingedly secured to the upper face of the bottom 2 are valves 17, which are adaptedto Patenten oet. 2e, woe.
extend over the ports 1G and normally close the saine to prevent the paint 'from passing through the llexible tubes lll, said valves being held in their normally closed positions by means ot springs 18, said springs being carried by a spider 19, the ends of which are attached to the bottom 2.
vIn order to open the valves 17 to permit the paint to liow through the flexible tubes ll, pins x20 are attached to the head 7 and ex tend upwardly Ythrough openings 2l in the disk lf, the upper ends of the pins engaging the lower t'aee ol the valves, and said pins are forced into engagement with the valves by the swinging or inclination of the head 7.
A downward pressure on the paint in the reservoir is aeconiplislnd by placing` a piston within the reservoir the( ialneter of 'Said piston being, such as to snuglyVV fit thereser voir and said piston is held against tilting within the reservoir by mea-ns of guides 23 placed at various points upon the piston and in `position to engage the wall of the reservoir.r Downward pressure is directed on the' piston S22 by means of a spiral spring 26, the
lower end ot said spring resting against the piston, while the upper end thereof engages the lower face of the covering 3 and as the paint is used :troni the reservoir, the piston will be moved downvardly by the pressure of the sprinv. Y p
ln order to depress the spring and place the piston in position for ready removal from or induction i ito the reservoir,a Acable 27 is attached at on end to the central or-A tion of the piston and at its'upper en to the lower end of ahondle 28, said handle exit-.ruling into asocket 29 formed integral with the upper face of the covering 3 and it will be readily seen that as said handle is moved upwardly through the socket, the piston will be likewise drawn upwardly une' til the ends ofthe guides 25 en age the lower tace ot' the covering, the han le being provided with a. vertical slot 30 and horizontally vthe slot 30, said handle may be elevated and theV lug broughtl into registration with the slot 32, when by rot-ating the handle in the opposite direction, the lug will be seated in the slot 32 and the piston retained in position adjacent the lower face of thev cov- Inaddition to the depending flange 4 for vholding the cover in engagement with the upper endv of the reservoir, a number of spring latches 34 are attached to the outer face of the reservoir, the upper ends of said latches having hook terminals 35, adapted to extend over a rib 36 around the edge of the cover and thus securely lock the cover in engagement with the reservoir.'
When the brush is filled and applied to use, the pressure of the brush against the obi ject will canse the head to tilt or swing laterally, which will force one of the pins 20 against its respective valve and open the same, whereby a (plantityA of paint will. be forced through. the feed tube and deposited 'in the bristles of the brush, the reverse stroke of the brush causing the valve at the opposite side thereof to be opened or if the brush is properly positioned, two of the valves will be opened simultaneously. In this manner, a predetermined quantity of the aint is fed into the brush, thereby avoiding wastage of the paint or the necessity of dippingthe brush into a receptacle containn ing the paint, thereby wasting considerable time in filling the brush.
What I claim` is:
l. In a self-feeding device, the combination with a reservoir; of a head below said reservoir, means to pivotally attach the head tothe reservoir, bristles carried by said head, tnbesextending from said reservoir'intosaid bristles, valves to normally close the upper @Sasse ends of said tubes, and means carried by the head adapted to open said valves when the head is rocked on its pivot.
2. In a self feeding brush, the combination with a reservoir; of a head having a conical upper surface, means to pivotally attach thev head to the reservoir, bristles carried by Asaid head, flexible tubes extending from th reservoir into said bristles, Valves abov the ends of said tubes, springs adapted to`nor mally retain the valves in their closed positions, pins carried by the head adapted to open said valves when said head vis rocked and means to direct pressure on the contents of the reservoir and cause the same to pass through said tubes.
3. In a self feeding brush, the combination with a reservoir, a brush taehed thereto and means to feed the' contents of the reservoir into said brush; of a piston in said reservoir, means to force said piston against the contents of the reservoir, a cover for the reservoir, a socket extending upwardly from the reservoir, a handle, a vcable extending from said handle to said piston and means to retain said handle in its adjusted position. 4. In a self feeding brush, the combination with a reservoir, a brush attached thereto and means to convey the contents of said reservoir into said brush; of a piston in said reservoir, a spring above said piston, adapted to direct downward pressure thereon, a cover for the reservoir, a socket for said cover, a handle entering said socket and having a vertical slot therein and a laterally extending slot at each end of the vertical slot, a lug on said socket adapted vto enter said slots, a cable extending .from said handle to said piston, whereby when the handle is elevated in the socket, the piston will beraised and the spring depressed, said laterally extending slots being adapted to hold the handle in its adjusted position.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
