This invention relates to improvements in a dispensing machine pertaining more particularly to a wheeled dispenser for dispensing or distributing cement or the like between or on the edges of roofing paper.

In the embodiment of the machine shown it is described as dispensing or distributing cement on the edges of roofing paper so that the edges of the sheets will have a waterproofed joint. It will be understood however that the machine or device shown can be readily utilized for distributing or dispensing any kind of liquid and can be used for other purposes than the specific specified use in connection with roofing paper.

One of the objects of the invention is to provide a novel construction of movable container adapted to discharge or spread liquid.

Another object of the invention is to provide a cement discharge or spreading device having a novel form of discharge spout and provided with a novel means for guiding the device to spread and distribute the cement in the desired places.

A still further object of the invention is to provide a wheeled discharging or spreading device for cement or the like which is provided with means for distributing the ocment, means for guiding the direction of movement of the device and means for forcing the cement from the device and controlling the amount of discharge through the distributing medium.

A still further object of the invention is to provide a wheeled force feed dispensing or distributing device for cement which is particularly adapted for use in cementing the overlapping edges of roofing paper or the like.

Another and further object of the invention is to provide a device of the character described which is cheap and simple of manufacture and highly eliicient in operation.

Other further objects. novel features of construction and improved results of the invention will appear in the following description and accompanying drawings.

In the drawings:

Figure 1 is a perspective view of the machine.

1928. Serial No. 308,837.

Fig. 2 is a detailed perspective view showing the dispensing or distributing foot or nozzle.

Fig. 3 is a vertical sectional view through the liquid pump and the-delivery conduit and conduit valve.

Fig. 4 is a horizontal sectional view through the lower end of the tank or container, the cover over the pump being broken away to show the pump gear arrangem'ent.

Referring now to the drawings in which like parts are designated by similar reference numerals, A represents a tank or container, B a running gear or supporting wheels for the container, C the handle shaft and D the handle for pushing the container. E represents the spreading or distributing foot or spout, F the liquid conduit, G the outlet valve and H the liquid pump. The machine guide is represented by K while L and M i'eipresent two sheets of roofing paper or the Describing the invention more specificall it will be seen that the container or tank is preferably cylindrical in shape having an open top 5 while its bottom is closed by a plate 6. The container or tank is supported through the medium of a horizontal shaft or axel 7 provided at its ends at either side of the tank with wheels 8 which may if desired be provided with rubber tires 9. The shaft 7 is supported in journals or bearings 10 at either side of the container or tank A as clearly appears in Fig. 4 of the drawings.

Motion is imparted to the supported tank A through the handle shaft C provided at its upper end with the transverse handle D. The lower end of the handle shaft C is provided with brackets 11 which extend downwardly between the tank and the wheels 8 and are supported as at 12 upon the shaft 7 of the machine.

To provide a means for stopping and looking the machine against movement there are provided brakes 13 which engage the wheels of the machine. The brake is actuated through the medium of a rod 14 which extends upwardly to the cross handle D where it is connected to a pivoted operating handle 15.

A housing 16 cast integrally with the bottom 6 of the tank and extending upwardly into' the same carries the meshing pump gears 17 and 18 which are provided at their under sides with studs 19 which are rotatably supported in suitable depressions 20 in the tank bottom 6; Adjacent the depressions 20 and surrounding them are larger depressions 21 in which the gears 17 and 18 rotate. The pump gear 18 is provided with an upwardly extending shaft 22 upon the upper end of which is suitably fastened a beveled gear 23 which engages the gear 24 carried upon the shaft 7 of the machine.

The housing 16 is closed at its top by a plate 25 which is provided with a bearing 26 for the vertical shaft 22 of the beveled'gear 23. This plate is providedwith an extension 27 which overhangs the rear end of the housing 16 which is open as at 28 to the tank.

' At its front end the housing 16 has communication as at :29 with the valve G which is contained in a cylindrical housing 30 which is cast integrally with the bottom 6 of the tank and in fact forms a part 'of t-he pump housing 16. -The lower end of the valve housing 30 is provided with a discharge opening 31 which gives communication with the conduit F which is fastened to the bottom 6 of the tank by means of screws 32 or the like. The valve G comprises a shaft 33 having an enlarged head the lower end of which is conical and projects into the discharge opening 31. In Fig. 3 of the drawings the conical end of the valve G is closing the outlet open- As clearly appears in Fig. 1 of the ing 31. drawings the shaft 33 of the valve G extends upwardly from the tank and has connection with an operating handle 34 which is pivotally mounted as at 35 to an upstanding car 36 which is fastened to the handle shaft C at a point to make the operating handle 34 convenient to the operator of the machine whereby the valve can be opened and closed at will.

The upper end of the valve housing 30 is provided with a hollow plug 37, in the upper end of which is screw-threadedly mounted a second hollow plug 100. The valve stem 33 extends through these openings. It will be seen that when the valve is in position as shown in Fig. 3, the liquid which is pumped will bypass above the valve around the stem and through the plugs 37 and 100, back into the tank.

Referring now to Figures 3 and 4 of the drawings it will be seen that the conduit F" extends outwardly to a position in front of the lower end of the tank or container A terminating in a cylindrical housing 38 the bottom of which is open as at 39 while its top is provided with an upwardly extending hollow open ended bearing 40. The foot or distributing spout E is rectangular in shape being hollow to form a conduit or chamber 41 in the bottom of which is the discharge opening 42 adjacent the outer tapered end 43 of the foot. The inner end 44 of the foot or spout is in communication with the open bottom 39 of the outer end of the conduit F being pivotally supported on the under face of the cylindrical end 38 of the conduit through the medium of the vertical shaft or bolt 45 which is suitably fastened a handle 50 through the I medium of which the foot or spout can be rotated upon its pivot to assume any desired position.

The machine guide K comprises sheet metal bent to form elongated U-shaped channels or grooves 51 and 52, the U of the channel 51 being open in the opposite direction of the U 52 so that the guide will operate even though the roofing sheet M is positioned to overlap the sheet L which would be the reversed. position of the sheets as they are shown in Figure 1 of the drawings. The guide K is supported upon a bracket 53 which is pivotally supported as at 54 upon the tank or container A and extends outwardly from its pivotal supporting connection.

It is found it is sometimes necessary to lift the guide K so that the machine can be run close to awall or chimney and to take care of this contingency a Wire 5411 has its one end connected to the guide and its other end connected to the handle D of the machine where it can be conveniently reached by the operator of the machine.

To insure a tight connection between the distributing foot or spout E and the conduit F a packing 55 is carried between their pivotal connection.

Operafz'on The operation of the machine is simple. The tank or container A is filled with cement or its equivalent and the machine positioned in respect to the roofing sheets I. and M, as shown in Figure 1. It is desired to cement the overlapping edges of the sheets L and M together. It will be seen that the edge of the sheet L extends into the elongated horizontal groove 51 of the guide K. The distributing spout or foot E is extending approximately at right angle to the conduit F so that its tapered end 43 is under the edge of the roofing sheet L between this sheet and the sheet M.

It remains now only for the operator to release the brake 13 from engagement with the wheels 8 by means of the handle 15 and to open the ivalve G through the medium of the valve o )erati'ng handle 34. The operator now pushes the machine lengthwise of the roofing sheets the machine being guided by the engagement of the guide K with the roofing sheet L.

As the machine is pushed forward the wheels rotate thus imparting rotation to the shaft 7 upon which they are fastened. The shaft -7 in turn rotates the shaft gear 24 which throi igh its engagement with the beveled gear 23 rfitates the pump gear 17 which in turn rotates the pump gear 18. The cement in the tank A is also in the pump housing 16 around the pump gears having entered through the open rear end 28 of the pump housing. As the pump gears rotate cement is forced forwardly by the rotation of the gears passing around the enlarged head 34 of the valve (1 and downwardly through the outlet opening 31, following the conduit F and eventually finding its way'through the chamber 41 of the discharge spout or foot E and out the spout opening 42.

As the discharge above takes place the machine is moving forward across the sheets and a line of cement is distributed or discharged between the overlapping edges of the roofing sheets L and M.

To complete the work it remains only to press the overlapping edges of the roofing sheets tightly together.

It will be readily understood that the amount of cement discharged through the spout or foot opening 42 can be controlled by the valve G. Attent on s further directed to the fact that the machine is easily guided through the medium of the guide K and that where it is necessary to distribute cement close to a wall or chimney the guide K can be lifted inthe manner heretofore described.

From the foregoing it will be seen that I have provided a cement distributing or spreading machine which is simple of construction, highly eflicient in operation and which can be manufactured and sold at a reasonable price.
