present invention. inits. broad'r aspect, has
reference to` improvements. in fountain toothr brushes wherein a-shaft is employed anda pis,- ton.. which4 is. detachable. from the shaft. The shaft has a valve-like end adjacent to a head and which in the passive condition of my tooth bruslrprevents passage ofdentifrice to the brush bristles, and.. which isadapted to be connected with.. the piston, andthe. shaft reciprocatedA in thet active condition of.: my toothbrush either to rell thev dentifrice reservoirV or discharge. dentifrice from the reservoir to. the bristles. Other. features ofV my inventionare.y (D the` pro.- vision. of improved air ventingv means,. (2)` the. provision of an improved arrangement ofv knurled nut to rotate theshaft to engage it in the inactive position with the dentifrice channel tothe bristles sealed and the shaft disengaged, (3') the provision of a novel and improved piston which in the inactive position isv disconnected` briefly outlined produces a simple, sturdy, de,-V
pen'd'able" and efficient fountain tooth brush wherein the dentifrice is contained in the handle* for'v dispensing as occasion requires, and which will not leak when not inuse and" which may be" conveniently carried in'k a hand bag or in the pocket.
Other and equallyimportant objects and ad'- vantagesv ofmy invention will be apparent from the. following description and" drawings, and ity ispointed out thatchanges in form, size, shape,
materials, and constructiony and arrangement' ofV parts ispermissible and within the purview of my' broad inventive concept, and the scope ofl the appended claims:

In .the drawings, whereinv like characters of reference are used to designate like or similar. parts;` The numeral' I' designates my brush head, and` 2 the shank, aipassage or channel 3' isformed in the brush` head and shank, and' communicates through ports 4 in the bristle disks` `Ei with` the bristle tufts 6j.- The bristle disksare threaded as'. at'l to be detachably engaged in the brushhead I. The shank is. threaded as at 3 to be engaged in thev end or head 9 of the handle I. A cap like. member l|` is cemented over the end and about end'ii'angesV l2 beneathwhich is a beveled knurled nutl i3, .the edges of which` extend through. slots andbeyondthe sur-face of thecapand` end tozbe graspedandzturned. to detachthe brushV head shank. 2- withwwhich it is threadedly engaged..

opposite end of which is held in place by a screw 21. Each plate has a beveled opening 28 to engage the sides of a conical latching member 29 which is pressed outwardly by a spring 30 in the bore 3| in the end and serves a purpose identical with the balls I 9 to detachably latch the cap 22 in place.
The handle I is oval in cross-section and hollow to provide a dentifrice receptacle 32. An end part or plug 33 closes the opposite end of. the handle and seats within its side walls. This part 33 has a central bore 34 which'is enlarged 4 end by screws 58. With the parts assembled as shown in Figs. 1 and 2 the ribs 54 coact with the knurled nut 5B whereby the shaft may be rotated with the end nut 52 in the recess in the member 51. Suitable packing 59 is located in the enlarged part 35 of the bore. To fill the receptacle 32 with dentifrice, the nut 56 is rotated to release the threaded part 55 of the shaft from the end 33. The nut 52 is then grasped and the shaft .39 retracted as shown in Figure 3 (air being exhausted through vent The beveled edge 44 of the head 43 seats on the beveled edge 48 of the at 35 and threaded as at 35 and leads into a cir- An operating shaft or piston rod 39 fits through the bore 34 and is longitudinally slotted' as at 4I) tof.
provide an air vent. The shaft is slidably and rotatably mounted and its upper end is pointed as at 4I to form a valve .engaging the seat I I on the end of the handle. The valve part 4I has a packing 42 and a disk-like head or valve 43 is mounted on the shaft back of the valve which has a beveled edge 44. Back of the head is an enlarged cylindrical threaded collar 45-see Figures 8 and 9. In the passive position of the parts of my device, the head'43 bears against the end 9 and the valve 4I .rests on seat II to close the channel 3 to prevent leakage of dentifrice from the reservoir into the brush head.
A loose piston pump 46 having packing rings 4'.'
is carried in the reservoir, and hasr a beveled edge 48 and a deep annular groove 49 receiving the spring 50, the opposite end of which seats in an 43. The piston has a threaded bore 5Ia and nor? mally rests against the end'v part 33 when the parts are passive as in Figures 1 and 2. At the opposite end of the shaft 39' is a knurled nut 52, an enlarged collar 53 having radial ribs 54 and a threaded part or plug 55. A knurled nut 56 is carried in the depression 31 of the end part 33.. The brush head is placed in the supplyof dentifrice and the dentifrice is drawn through the head, channel 3, and opening I4 in the end 9,'and into the receptacle 32 in the handle, that is the dentifrice is simply sucked into the receptacle. In this operation the piston rod 39 and head 43 are drawn outwardly by the knurled nut 52 and the threaded part 45 threaded into the sleeve in the piston. The piston is then forced inwardly as the brush head is placed in the dentifrice and as the piston is drawn outwardly to the position shown in Fig. 3 the dentifrice is drawn. into the opening 32 in the .handle to flllkthe handle. The shaft 39 is thenturned in the opposite direction to remove the thread 45 from they collar of the piston and the piston` rod is moved inwardly with the member-4I coacting with the seat IIto close the passage from the handle to the brush head. The shaft is then pushed in and is urged by spring 50until valve 4I engages seat I I' vand the head 43 bears against the end 9 to seal thev receptacle as shown in Figures 1 and `2, in which position the threaded part 55 is engaged of the piston 46 and is accessible through slots 38, and is internally bored and keyed to engage g collar 53. In the passive position. the threaded part 55 is engaged with the threaded part 36 of 1 theend 33, and the knurled nut 52 is in anopenannular groove 5I in the under side of theihead .35"
piston. The valve 4I is withdrawn from its seat I I and opening I4'and channel 3 are open for passage of dentifrice to the bristles. The shaft is moved in and out until sufficient dentifrice is dispensed to the bristles, whereupon the tooth brush is ready for use and the shaft is returned Vto its passive position of Figure 1.
From the foregoing, it is believed that the op eration and advantages of my invention will be apparent, but it is again pointed out that interpretation of its scope should only be conclusive when made in the light of the subjoined claims.
