' Application July 15,1943, Serial no. 494,806 1 Claim. ((172-128) This invention relates to implements employed in the erection of masonry and concrete structures andthe like, and more particularly to a combined gravity-flow plasticcontainer and assov plement.

ciated spreader guide and s ge, broadly termed a trowel, in the specification and clalm which maybe employed to spread ribbons of mortar'on brick orblock courses. .a i H Animportant object of the invention'is to pro vide such an implement, which supplies a ribbon of plastic of a uniform thickness andwidth.

'Anotherimportant object is to provide a trowel or implement-of this kind, which'supplies' a ribbon of plasticwith. the vertical sides of the ribbon spaced a uniform distancefrom the planes of the virtical sides or faces of the bricks, blocks or the li e.

Still another object is to provide a valved container for plastic (such as mortar), and an associated channeled guide and gage carried by the container and disposed below the valve, with a passageway to the guide when the valve is unseated.

- Another important object is to providea mortar spreader which will minimize waste'of the- Yet another object is to provide a valved container for mortarami anassociated guide and spreader, which may be wholly manipulated by one hand of the mason.

Still another object is to provide such an implement wherein the operator will be aware at all kings of the quantity of plastic within the eon- Other objects and advantages of this invention will be apparent during the course of the follow-- lug-detailed description of the invention, taken in connection with the accompanying drawing, forming a part of this specification and in which drawingz, I

Figure 3 is a bottom planof the'novel trowel or implement. Figure 4 i anperspectiveview, showing rib.-

- bonsai mortar bein spread along the upper faces .of a course of concrete blocks, I I In the drawing, wherein for the purpose of iilustration is, shown a preferred embodiment of the invention; and wherein similarreference char-.- acters designatef'corresponding parts throughout' ll handle means l2 to move the implement along the course, and valve means l3, between the'con-r tainer or the reservoir l I and spreader and guide means ID.

As for the spreader and guide same comprises an inverted, elongated, channel shaped member it, having Opposite sidewalls I6 and H, the first being termed the outer side wall and the latter the inner side wall. The outer side means It, the

wall I8 is deeper than the side wall H, as shown particularly in Figure 2,. and is provided with a substantially flat face l8, with the lower portion of this face It adapted to slide along the upper portions of the side walls of conventional bricks and building blocks. The side wall II has a substantially fiat lower edge I 9, adapted to slide over a portion of the upper faces of these bricks or blocks. Anupper or top, horizontallydisposed substantially flat wall 20 Joins the wallsl6 and I1 and is provided with an opening or passageway II, somewhat oval in shape, as shown in Figure 3, preferably disposed intermediate the ends of the member II. The member i6 is free of end walls,

'so that there is provided an elongated passage way 22 through the member ii, in communication with the passageway 2| and of an area greater than the area of the passageway 2 I Preferably disposed directly over the member II is the container-or reservoir l8, somewhat funnel-shaped, as in Figures 1 and 2, having an open upper mouth 25, side walls 26 and end walls 21 with the walls converging downwardly to meet the wall 2| at the passageway 2 I. The lowermost portions of the inner faces of these walls 26and 2lprovide a valve seat 28. 'The reservoir i6 is preferably what the word implies-a container for .a' considerable supply of material, which may be drawn upon to supply measured volumes of material to 'the mean it, and is not, primarily, a container such as a conventional trowel for a small volume of material. Infant, in practice, it has been found feasible to provide a container of a 12 quart capacity. The means Ill and II may be integral or'may be separate parts joined together as by welding. Since some plastics, such as mortar. are inclined toadhere to the walls of a container, a suitable on, as thin waste engine oil 29, may be applied to the walls 28 and 2.1.

, The handle means I2 is shown as comprising a; substantial straight, round rod Ill, bridging the mouth 25 of the reservoir it, having a head 3| at one end and any suitable means, such as a pin 32 at the other end,-with the rod 30 secured in suitable openings in a pair of ears 33 extending upwardly above the 'mouth 25 from opposite sides upper end to provide the twospaced-apart, semicircular handle-engaging portions 31 and 38, shown in Figure 2, the extremity I! will have a tendency to spring toward the facing portion of the stem; When the portion 31 is about the rod 30 (as shown in dot-and-dashes) the valve 35 is seated and when the portion 38 is about therod '30 (as shown in full lines in Figure 2) the valve is unseated, and plastic material may flow through the pafssagewayjl, until. the operator disengages the ortion 38 from the rod 30, whereupon suction contact with the upper portion of one side face 42 of the block 40. When the valve 35 is unseated, as by drawing up on the valve stem 36, the plastic B will flow through the passageway 2| and into the passageway 22- and fill it. Upon moving the implement along the course, guided by the elongated side wall IS in contact with the faces 42 of the blocks 40, uniform ribbons 43 of mortar will be spread along the upper faces 4! of the blocks 40 ready to receive the next course of blocks. It

will be noted that the ribbons 43 are so disposed.

that material will not be wasted, as by dropping into the hollows 44 of. the blocks 40, there is a neat, outer edge of mortar, uniform in thickness, and with this edge paralleling the vertical planes of the adjacent side faces 42 of the blocks, and all this is accomplished rapidly, with the operator, looking down upon the work and container, able to ascertain at all times the volume of plastic B in the open-mouthed reservoir.

Various changes may bemade to the form of the invention, herein shown and described, without departing from the spirit of the invention or scope of the following claim. 4

What is claimed is A- trowel adapted to form ribbons of mortar along the upper faces of bricks. blocks and the like, comprising a reservoir, having an open, up

. wardly-extending mouth and an exit at its lower end; a handle bridging said mouth with the vertical longitudinal plane of said handle substancreated by the flowing plastic B will draw the valve 85 to a seated position and the portion I! will then engage the rod ll.

Operation of the novel implement is by hand. After the reservoir II is suitably coated as des"cri bed, arid the valve IQ is seated, a volume of plasticB, as mortar, is poured into the reservoir l6. Whena course of the material C, such as hollow concrete building blocks is laid, the oporator lifts the implement, by the rod handle an tially bisecting said reservoir, said handle being secured at adjacent its ends to said reservoir; and a valve for said exit, having a stem extending upwardly through said reservoir to said handle and provided with means to suspend said stem from said handle at selected distances above said firstnamedpassageway, said last-named means including a resilient U-shaped arm having a pair of handle-engaging sections, shaped .to conform to and sets it upon the upper face 4'! of. asuitable block, with the inner face I! of the elongated side l wall'l of. the spreader and guide means II, in

a portion of the transverse cross-section of said handle.
