OASTLEMAN DAVID DOLL, OF' LGUISVILLE; KENTUCKY.

Mosman-@READER To all whom t may concern: Y

Be it known that I, CASTLEMAN D. DOLL, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful improvements in lViortar- Spreaders; and l do declare the following to be la full, clear, and exact description of tlie'invention, such as 'will enable others skilled in the art to whichit appertazins to ineke and use the saine.

rlhis invention relates to improvements in mortar spreaders designed tobe moved over the top of a wall for depositing a layer of niortar thereon.

Y The priniary object of the invention is to provide a device of this character' so con-V structed as to deposit a layer of uniform thickness and having means under control of the operator forregulating thethickness of the layer deposite Another object is to provide a spreader with simple and efficient ineans for dividing the deposit of plastic material into two parallel llayers arranged side by side.

Another object is t0 .Provide simple and eiic'ient ,means for cutting olf the 4feed of inegi-tar when desired. i

lJVith these and other objects in view the invention vconsists of certain novel lfeatures of construction and the combination and arrangement of parts as will be more fully de scrib'edend claimed. Y

In the accompanying drawings, Figure 1 represents a perspective view of this iniproved spreader taken from the rear; Fig.

2is ,a longitudinal vertical section,thereof;` Fig. 3 is a horizontalsection taken on the line 3 3 of Fig. frFig. 4 is a bottom plan view .,thereof; Fig. 5 'is a rear'elevation of a portonof ythe spreader; Fig. 6 is a front elevation thereof; Fig. 7 is a detail perspective view of a controlling Vgate or valve.

In the enibodinient illustrated a receptacle lis shown in the 'forni of a rectangular ves,- sel open at its top and provided with a bail 'shaped handle 2 connected. with ythe end ,Y members thereof and which is designed forI vtransporting `the device or for lifting it from Vplac'eto place. lThis receptacle'l is provided in its Ybottom at one end with an opening 3 through which the mortar. contained in the receptacle is designedtobe fed. A slanting partition isarranged within said receptacle l andinclines frointhe front wall thereof at y a point near the .top downwardly j t to receive fastening elements for connect- "ing it to the sidewalls of the receptacle l. This inclined partition or false bottoni l is designed to insure the feeding of the mortar through the opening at the rear of the vreceptacle serving' -to direct it downwardly thereinto.

The rear end wall 5 ofthe receptacle is provided at its lower end with a transversely extending open-ing 8 the height of which controls the thickness lof the layer of mortar to be spread and this 'opening is controlled by a pivotally inountedgate or valve l0 to be described. Extending transversely across the end wall 5 attghe top ofthe opening 8 is an outwardly projecting -lip -9 which may be of vany desired width and is designedfor co-action with the gate 10 for varying the height of the opening -8 and is designed lto close theV space between the upper edge ofthe gate valve andthe outer face ofthe wall 5 when the valve isv lowered either partially or entirely, the rear edge of said lvalve ylapping said lip and being here shown arranged in Voverlapping relation, it being necessary to have the upper or rear edge of the valve -wardly -froni the side walls of the receptacle" l` at vthe 'lower end thereof aretwo flanges 1l which -forin guards designed toprevent the mortar fnoin dropping over the sides ofthe 'brick duringthe operation ofthe spreader.

The gate valve 10 is here shown arcuatein cro-ss sectional contour and of a length equal zto the width of the rear end ofthe receptacle i1 and is provided at its ends with llaterally extending inturned apertured ears l2vher'e shown triangular in forin with their bases or wider portions secured tothe ineinber l0 and their apices extending outwardly at the 'free ends thereof which apertures areplaced `for pivotallyA lconnecting thein with the specification of Letters raient. imaging@ NV, 2, '1.915, Application filed April 8, 1915. Serial No. 20,010.

flanges 11 at opposite sides of the receptacle to provide for the upward and downward swinging of the gate in the arc of a circle,

ends preferably midway of its length with a vdepending lug 13 which is designed to rest on'the wall over which the spreader is drawn yto separate the mortar kfed by the @spreader into two parallel layers arranged Lsideby side said lug 13 being here termed 'adividen j- WA strap '1d gate val-ve being vhere shown connected midway Vthe ends thereof in alinement with is cdnnected one end to the the divider 13. Y The free end ofthe strap 14. is arranged at an angle to the body portion thereof and is designed to lie flat against fgaged with, a bolt 15 which extends through the outer faceof the end wall 5V and is enagfjilongitudinally disposed slot 16 formed in the wall 5 and by means of which the gate valve may be adjusted vertically and locked in adjusted positionv by means of a winged nut 16 to regulate the thickness of the layer of mortar to be. spread, the lower edge of said Yjgate passing overl the mortar fed i through. the opening 3 and thus :smoothing it off and controlling its thickness.

n A slide 17 is Imounted for longitudinal movement overthe bottom of the receptacle 1 and ris designed to close the opening 3 at the rear end thereof when it is desired to I Vlift. the receptacle from place to place or when it is yto be transported for any distance.

'ThisV slide 17 is'here shown mounted in Yguides 18 at the opposite side edgesof the bottoni portion o-f the receptacle. (See Figs.

5. and 6.) This slide 17 is of a length slightly greater than the length of the opening 3 in the bottom of the receptacle and is designed when in closed position `to completely close thereceptacle to preventfdropping out of the mortar through said opening. Hingedly connected to the front end .j Y of this slide 17 vis an Voperating handle 19 here shown in the form of a metal bar con- -nected at one endto the slide 17 and having 'its f-reeend bent laterally as shown at 2O to `provide a finger grip for operating the botgtom17 for` sliding itv back and forth in the guides 18 for opening and closing the opening3. j When `invopen Vposition this handle 19 will .project beyond the front end of the receptacle and it is adapted tobe arranged in upright position as shown in Figs. 2 and :.6 an'djheld in this position by a spring clip lse 221 secured to the vouter face of the front wall 5 of the receptacle. When it is desired to close the lslide this handle 19 is disconnected from the clip 21 and is moved inwardlyby the operator thereby causing. the

opening 3 V`.slide 17 to move rearwardlyand close the 6b' J and when in this position 'said handle 19 will project a slight distance only beyond the fiont wall of the receptacle but not far enough to be in the way of the operator.

From the foregoing description taken in connection with the accompanying dranings, the construction and operation of this improved spreader will be readily understood without requiring a more extended explanation.
