expensive device for said purpose. This object and features of my invention are hereinafter fully set forth, reference being had to thefaccompanying drawing, in which,-

Fig. 1 is a top view of my device including a gage clip used on its front end when filling vertical seams of walls. Y Y

Fig. 2 is a side elevation of Fig. 1 and Fig. 3 is a front end elevation of the device.

Fig. 4 is a side elevation ofthe device in upright position and its rear part expanded or spread open for the purpose of pouring a quantity of mortar into it. Y

Fig. 5 is a perspective view of the gage clip 25 of my device. l

Fig. 6 is a face viewof a position of a brick wall showing the seams to be filled or finished with my improved device. l

Referring to the drawing by reference numerals, my device comprises an elongated back or base board 10 and a corresponding but shorter pressure board 11 andvbetween said two boards is provided, on three sides, front and two opposite sides, a continuous flexible wall 12 with corresponding flanged edges 12E suitably fixed to the side edges of the adjacent faces of said boards and to the front edge part of board 1l (see Figs. 1, 2, 3 and 4).

The lower front part of said wall material 12 is not, however, fixed to board 10 but forms an inverted U-shaped', forwardly directed opening adapted to be fixed exteriorly of and on the rear part of a flat-mouthed outlet spout 14-15 by suitablek means such as a metal band 13. The mouth of said spout comprises a transverse opening forward of base 10, said opening being adjustable for suitable outlet width of mortar desired to fill the seams of a wall and designated as 16.

The spout comprises a sheet metal plate 15 fixed on front end of base 10 and having two parallel upright flanges 15F near its opposite side edges. The other part 14 of the spout has corresponding downward side flanges 14F (Fig. 3) adapted t0 oscillate each par- 1929. serial No. 372,620.

allel and close to a fiange 15F and the means for oscillating member 14 comprises a pair of side ,ears 14E each with an aperture for a stud 17 to project through, said stud being suitably fixed in base 10. On each stud 17 55 above its ear 14E is a thumb screw 19 adapted to be adjusted downwardly against the action of a compression coil spring 18 between each ear and the base 10. Thus it will be readily understood that the opening 16 may be any 60 thickness desired within the limits of adjustment by the thumb screws 19.

n The flexible wall 12 is preferably a heavy rubberized canvas or other suitable fabric.

F or afclear understanding of the use yof first been set in upright position as in Fig. 4 70 and the boards 10,-11 spread from each other as far as possible.

After filling in mortar as to level 21, (Fig. 4) the adjacent rear ends of boards 10-11 are pressed toward each other to close the rear end of the device and the said end parts may then be clamped together by any suitable meanssuch as the hinged spring jawclamp22 of shallow U-shaped rarranged to clamp the closed ends of 10-11 as in Fig. 2. The clamp 22 is shown hinged to member 11 and mayhave an inward curvature as 22C to engage in a grooved part 10C of base board 10. Obviously when the device is partly filled with mortar' and the rear part ofthe device is closed as described the front end of board 11 will be forced to spread away from board 10 (see Fig. 2) because of said mortar therein. The operator then grasps the device on both sides, at the middle, with his fingers under board 10 and his thumbs engaging on top of board 11, then holding the spout parallel to a wall seam 23 (as in awall 24) and exerting pressure on board 11 with his thumbs the device actsas a bellows, forcing mortark from the spout into the wall seams filling themas the operator moves along the seam, assuming such seams to be continuous, as

thoseshown horizontal iny Fig. 6. In apre-` ferred size of my device the spout opening 16 10 Stir is too long for proper filling of vertical seams 23, the latter in brick walls being only about 2 inches long. My device is useful also for such vertical seams, as I have provided a spring sheet-metal clip 25 tor this purpose, said clip being of lJ-shape in cross section and adapted to be slipped on the outlet of my device and retained thereon frictionally.

The clip must be of such length as to shut ofi outlet of mortar from the spout except for an opening sutiicient to permit outlet Of mortar suilicient to till a vertical seam 23 as between two alined bricks, said opening be ing' as between lines ii-B of Fig. l. In lilling vertical seams as described the device must be held in such position that its elongated spent opening is in Yforti-cal plane.

rI'he operation and construction oit` my device in a preferred form have been fully disclosed. It is obvious that a number of details i of construction may be embodied without departing from the scope and spirit of the invention. For example, the closing means for the rear end ot the device may comprise other mechanical means, and the thumb screws 19 may be of such construction as to positively engage and raise or lower the spout section lll as desired without the use of compression springs I8. The main body ot my device is mentioned a bellows structure but used to squeeze mortar from its normally Widest end while its opposite end is closed.

I claim:

l. In a mortar filling device of the class described, a pair oi elongated normally parallel board members alined at one end and one ot said members shorter than the other, a metal outlet spout mounted on the longer board beyond the other end of the adjacent shorter board, said spout having an outlet transversely ot the board and parallel to and outwardly oi the forward end of said board, a flexible wall member connecting to the adj acent parts ot' said boards at their side edges and having a. forwardly directed opening arranged to communicate with the rear part of said spout.

2. The structure specified in claim l, and said Vspout comprising a fixed flat plate. part secured on the longer board and an upper part with a plate parallel to said iixed plate and means for adjusting said upper plate with relation to the fixed plate for selective amount oi" opening therebetween, and means for shutting oli a portion of said variable i opening.

3. The structure specified in claim l, and said spout comprising a iixed flat plate part secured on the longer board and an upper part with a plate parallel to said fixed plate and means for adjusting said upper plate with relation to the ixed plate for selective amount of opening therebetween, and means for shutting oli a portion of said variable opening Vcomprising a sheet metal clip of predetermined length and of U-shape in cross section, said clip adapted to be slipped over the spout opening and trictionally engage same.

e. In a mortar filling device of the class described, a pair ot elongated normally parallel board members alined at one end and one of Said members shorter than the other, a metal outlet spout mounted on the longer board beyond the other end of the adjacent shorter board, said spout having an outlet transversely of the board and parallel to and outwardly of the forward end ot said board, a fiexible wall member connecting to the adjacent parts of said boards at their side edges and having a forwardly directed opening arranged to communicate with the rear part ot said spout and means for closing the adj acent rear end parts of said board members toward each other and holding them closed for the purpose set forth. n

5. A mortar joint and seam .filler comprising an elongated rigid base member, a spout mounted at the :front end thereof and having an outlet transversely ol the said base beyond its front end, an elongated pressure member shorter than the base member and normally in spaced relation to the latter and both said members connected with their rear ends in common plane with the front end ot the compression member in spaced relation rearwardly of the said spout; means forl holding said rear end parts clamped toward each other, the means for connecting said members comprising integral flexible side and front walls, said front wall provided with an outlet part securable to the rearwardly opening part of said spout, said rear end closing means adapted to be released to permit spreading of said base and compression mem bers, for the purpose described.

In testimony whereof I affix my signature.
