3 Claims. (61. 221-1) My invention relates to a dispensing apparatus, and while primarily intended for distributing liquid asphalt or analogous filling material into crevices or cracks in floors or roads or 116 into theinterstices between spaced tile or other work, it will be obvious that the device may be employed for any other purposes wherein it is found to be applicable.

Important objects of the invention. are. to

*1) provide a portable dispensing .apparatus of the character described, which may be conveniently operated by a single workman to direct the fillingmaterial into crevices and for controlling the flow therefrom, which is simple in its con- ;15 struction and arrangement, compact, efficient in its use, and economical in its manufacture and use. 1 i i "T the accomplishment of these and such other objects as may hereinafter appear, the

120 invention consists of the novel construction,

combination and arrangement of parts herein specifically described and illustrated in the accompanyingdrawing, but it is to be understood that changesin the form, proportions and minor details of construction may be resorted to that come within the scope of the claims hereunto appended. 1

In the drawing wherein like numerals of reference designate corresponding parts. throughout the several views:

Figure 1 is a side elevational view, partly in section, of a dispensing apparatus constructed in accordance with the invention. 7

Figures 2 and 4 are approximately full size views of the control handlewith associated parts, the former being a transverse sectional view, and the latter a front view thereof.

Figure 3 is ,an enlarged fragmentary sectional View of the discharge end of the device.

Referring in detail to the'drawing, 1 denotes a cylindricalreservoir or tank having its rear end closed by a permenantly secured end wall .2. .A- conically-shaped spout 3 is permanently securedto the front end of the tank, and terminates with a slotted neck 4 at the forward reduced end thereof.

A filli-ng opening 5 is formed in the top of the tank 1 adjacent to the rear end thereof. A. comparatively shallow hopper 6 is fixed to the tank and surrounds the opening 5 to facilitate the filling of the tank without liability of spilling the filling material.

A suitable foot 7 is secured to the bottom side of the rear end portion of the tank 1 for preventing the rolling of the apparatus to mainstraight forward portion 19,

tain the filling opening 5 at its proper top position, particularly when the device is resting upon the ground or any other support during the filling operation, whether or not the apparatus is in use.

The dispensing apparatus is manipulated by a pair of roller-type handles, respectively indicated' at Band 9.- The handle 8 is carried by a pair of legs 10 fixed to the end wall 2, and the handle 9, employed for supporting the device during the liquid dispensing operation, is carried by a pair of vertically disposed legs 11, which are fixed to the top of the tank 1 about midway between the ends of the latter.

As the filling material employed is usually heated to a high temperature to render same liquid for pouring purposes, the handles 8 and 9 are preferably constructed from wood or other suitable material insulating same from the heat of the tank when filled with pouring material. A tapering discharge nozzle 12 is detachably connected to the front end of the spout 3. The nozzle is provided with a shank 13, which is frictionally extended into the slotted spout neck 4. A collar clamp 14 surrounds and compresses the latter for securing the nozzle in position.

The nozzle 12 is provided with a tapering bore 15, which terminates at its front end with a comparatively small exit aperture 16. A needle valve 17 is mounted in the nozzle bore 15 and is longitudinally operable in the latter for opening or closing the exit aperture 16.

The valve 17 is fixed, in any suitable manner, to-the forward end of an elongated connecting rod 18. The latter is flexed to provide the carrying and aligned withth'e valve 17, and the straight rearward portion 20, which extends parallel and adjacent to the top of the tank 1 and projects through an aperture 21 provided therefor in the rear end wall 2.

.A bearing bracket 22 is fixed to and depends from the top of the tank 1 adjacent to the rear end of the latter. Another bearing bracket 23 is fixed to and extends horizontally across the front end of the tank. The rearward rod portion extends through the bracket 22, and the forward rod portion 19 passes through the bracket 23. The provision of the bearing brackets 22 and 23 maintains the connecting rod 18 in proper alignment by preventing undue flexing of the latter or any other untoward condition tending to impair the proper seating of the valve 1'7 during the filling and pouring operations.

An important feature of the present invention resides in the novel operation and control of the valve 17 by elements actuated. by the manipulation of the handle 8. The legs 10, supporting the handle 8, extend obliquely upward to dispose the latter rearwardly and slightly above the top of the tank 1. The handle 8 is revolubly mounted on a bolt 24 between the free ends of the legs 10. The belt 24 has a squared end 25, which engages in a, correspondingly shaped aperture in one of the legs 10 to prevent its turning in the latter.

An operating arm 26 is secured to and depends from the center of the handle 8. The lower end of the arm 26 is provided with a longitudinally extending slot 27, and is pivotally joined in the forked end of a coupling member 28 by means of a pivoting pin 29. The latter is carried by the coupling member 28 and extends through the slot 27.

The projecting end of the rearward rod por tion 20 is threaded, as at 30, and engages in a threaded aperture 31, formed in the coupling member 28, to permit of the adjustment of the latter on said rod portion 20. A locking nut 32 is mounted on the threaded rod portion 30 and adjustable to engage the coupling member 28 for the purpose of securing the connecting rod 18 against rotation, as such rotation of the latter, due to its fiexures, would obviously tend to disturb the proper seating of thevalve 17.

It will be evident that a partial rotation of the handle 8 in either direction will cause the valve 17 to shift longitudinally in the nozzle bore 15, and respectively open or close the exit aperture 16. As clearly shown in Figure 2, the arm slot 2'7 will compensate for any directional variation of the operating arm 26, and permit of the free straight movement of the rod portion 20 through. the aperture 21 without binding and without disturbing the parallel relation of said portion 20 with respect to the top of the tank 1.

A disk cam 33 is mounted on the threaded end. of the bolt 24 and consists of an inner portion 34 secured against rotation, and a revolubly mounted outer member 35, which latter may be adjusted by means ofa nut 36 engaged on the bolt 24. The outer cam member 35 is provided with, an operating lever 37 extending vertically upward and projecting above the upper end of the adjacent handle leg 10. The lever 37 is conveniently positioned to permit the manipulation of the cam elements by the operators hand while gripping the actuating handle 8. By shifting the lever 37 in either direction the action of the cam 33 will draw the upper ends of the legs 10 toward each other against the respective ends of the handle 8 and clamp the latter against rotation, whereby the valve 17 may be secured in the closed, open, or any desired adjusted position. I

A spiral spring 38 is preferably though not essentially mounted on the rods rear portion 20'within the tank'l. One end of the spring abuts against the rear end wall 2, and the other end thereof abuts against a washer 39, which is held in position on the rod portion 20 in any suitable manner to prevent its forward movement on the latter.

While the normal action of the spring 38 will obviously tend to force the connecting rod 18 forwardly to shift and hold the valve 1'7 in the closed position, the primary purpose of the spring is to provide a perceptible drag against a too free action of the valve operating elements, and thereby facilitate the adjustment of the valve 17.

It will here be noted that the tank opening 5, the rod aperture 21, and the spring 38, are all positioned adjacent to the top of the rear end of the-tank 1 and, consequently, are reasonably remote from continuous contact with the filling material used or stored within the tank.

The present invention provides a most efficient device of its kind, which may be conveniently handled and operated by a workman for rapidly filling cracks and interstices with a perfectly controlled uniform flow of filling material,
