DISPENSING DEVICE Filed Jan. 27, 193"! Patented Jan. 18, 1938 UNITED STATES PATENT oFFicE DISPENSING DEVICE Robert E. Perry, Chicago, Ill. v Application January 27, 1937, Serial No. 122,492 14 Claims. (Cl. 221-65) in a dispensing device into open or closed posl-.

tion.

Another object is to provide a device of the character referred to which is inexpensive to construct, easy to assemble, positive in operation and readily actuated.

The foregoing and such other objects of the invention as will appear hereinafter as the description proceeds, will be more readily understccd'from a perusal of the following specification, reference being had to the accompanying drawing, in which: I

Fig. 1 is a perspective view of the improved dispensing device.

Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1 showing in dotted lines a portion of a tooth brush inserted therein.

Fig. 3 is a fragmentary rear elevational view of the device.

Fig. 4 is a vertical sectional view taken subupper end, both of which preferably are formed from sheet material, such as steel, bent substantially to the shape illustrated. A cover l3, pref- .erably hinged along its rear edge at it, is adapted to close the open upper endof the hopper i2'and the lower or bottom wall l5 of said hopper is inclined downwardly toward a substantially centrally located elongated discharge opening IS. The opening l6 preferably has downwardly extending flanges li therearound, the lower edges of which preferably are securely ,joined to an apertured substantially horizontal bottom plate l8 rigidly mounted within the-casing H.

Depending from and secured to the bottom face of the plate i8 in axial alignment vertically with the flanged opening it is a substantially U- shaped member l9 which defines a brush receiving chamber 2i. The chamber 2! opens at both fully described hereinafter.

the front and the rear of the casing II and preferably has suitable downwardly inclined flanges 22 on its side walls for a purpose to be more As best shown in Figs. 2 and 4, the opposed flanges 22 preferably terminate short of the rear face of the chamber 2 I.

The bottom wall or plate l8 preferably is cut out adjacent its rear edge, as at 23, and has downwardly extending opposed ears 24 which are apertured to receive a pintle 25. The pintle 25 is rigidly secured to and-adjacent the upper end of a trigger 26 which depends downwardly into the chamber 2|, as shown. The upper extremity of the trigger 26 terminates in an arm 27 which extends transversely of the casing M and then rearwardly substantially parallel with the elongated fla'nged discharge opening IS. The free end 28 of the arm 21 is suitably onset and slotted to receive the end portion 29 of a rocker shaft 3| which is journalled in the inclined bottom of the hopper i2, preferably on one side of the elongated discharge opening i6 and has thereon agitating members 32.

A lever 33 is fixedly pivoted at St, adjacent the forward end of the hopper l2, and extends rearwardly along one of the side flanges l'li parallel to arm 21. The free end of said lever is bent transversely and slotted at 35 to receive the offset end 36 of one of the valve bearing trunnions 31. A pin 38 is secured to the lever 33, substantially midway between its ends, and is connected at 39 to the free end of the trigger arm 27 by a tension spring 4!. The valve hearing trunnions 31 are journaled in the end flanges ll of the discharge opening is and are secured one to each end of a reciprocably rotatable valve 42 which is mounted in the opening l6.

As best shown in Fig. 5, the valve 52 preferably consists of a substantially semi-cylindrical body having a curved wall 83 and a substantially straight wall M extending at right angles thereto. When the valve is in its normally closed position the straight wall 44 extends substantially.horizontally across the bottom of the discharge opening it. Upon being rotated substantially 45 degrees thestraight wall 44 is moved into a substantially vertical position and the curved wall 43 is moved into a position horizontally across the opening l6. Obviously only a predetermined amount of the contents of the hopper, as determined by the size of the valve, is discharged upon its being moved from closed to open position.

Movement of the valve 42 is accomplished by inserting a tooth brush ll, or other device, into the c amber 2i and urging it rearwardly into positi e engagement with the trigger 20. Continned rearward movement of said brush urges said trigger into the position substantially as shown in dotted lines in Figs. 2 and 4. This movement of the trigger carries the free end of the arm 21 downwardly below the fixed pivotal center 34 ot the lever I3. Due to the toggle action of the tension spring ll connecting said arm with the lever 33, said lever is thrown quickly into its lower or dotted line position (Fi 4) to rock the valve 2 into position to discharge the contents thereof onto the brush.

During movement of the arm 21 downwardly,

the bent end 29 oirthe rocker shaft 3| also is moved into its lowermost position, turning said shaft a part of a revolution to move the agitating members -32 from one to the other side of the hopper. Upon withdrawal of ,the brush. the

spring I quickly returns the parts to their nortity of the contents or the hopper onto a tooth brush or other article inserted into the chamber 2| and although an exemplary form 01' construction has been shown and described herein in detail it is obvious that the device may embrace certain variations in the detail construction and specific arrangement of the individual parts without departing from the spirit of the invention or the-scope of the appended claims.
