This invention spreader mold. 7

*It is annedto provide an effic1entconrelates to aconcrete struet'ion whereby the frame for 'making variouslengths of concrete spreaders, 13 21Cljustable in anovelmanner.

Another object is to provide such a. construction wherein wedge-shaped pins may be used if desired to form openings to accommodate bolts to be used in connection with the Spreaders.

Another object isto provide the device of such construction as to have relatively movable parts coacting to produce the novel results.

Various additional objects and advantages will in part be pointed out and in part become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a plan view of the mold;

Figures 2 and 3 are opposite end views thereof;

Figure 4 is a longitudinal sectional view on a plane indicated by the line 4-4 of Figure 1;

Figure 5 is a transverse sectional View on a plane indicated by the line 5-5 of Figure 1;

Figure 6 is a perspective view of the base;

Figure 7 is frame;

Figure 8 is a perspective view wedge-pin; and

Figure 9 isa perspective view of one of the concrete spreaders and provided with attaching members.

In carrying out the invention, a suitable base is provided as at 10 which may be adapted for stationary disposition and sup port in any desired manner. At one end of the base 10 are upstanding plates 11 and 12 spaced by a slot as at 13.

Coacting withthe base 10 is a frame or body 1 1 which may have side walls 15, an end wall 16, a connecting bar 17, and a partition wall 18 secured to the connecting bar and to the front or end wall 16. V The frame is slidable over the base 10 with the bar 17 disposed in the rear of the plates 11 and 12 and with the partition 18 and end wall 16 a perspective view of the .of the resting directly on said base. The walls 15,

however, depend belowthe end wall 16, partition 18 and bar 17so as to overlap the sides of the baseand thus constitute a guide for the movement of the frame.

The-said coacting base and frame form poc kets or mold cavitiesiat 19 andwQO, in which .spreaders of concrete or the like .21 areadapted to be'molded or made, it being obvious thatl the body 14: tlirough adjustmentmay vary the size of the Spreaders to be made since it varies the distance between the plates 11 and 12 and the end wall .16. The spreader; of concrete made by the de vice may be used in place of the usual wooden spreaders for concrete mold forms. as in the making of concrete walls by pourine.

The plate 11 and end wall 16in line therewith may have openings 22 and 23, respectively therethrough, to accommodate wedge pins 2 1, removably, and selectively forming a cylinder, so as to provide an opening in the spreader 21 cast in space 19, such opening being adapted to accommodate bolts 7 that may be inserted to hold the concrete forms together in practice.

On the other hand, the spreader 21 may be of solid concrete and have fastening ele ments such as metallic nail-accommodating strips 25 fastened at one end therein. The solid spreaders are made in the Space'QO since the plate 17 and portion of the end wall 16 opposite the same are imperforate.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

That is claimed is p 1. A device of the class described comprising a. base member, a frame member, one of said members being movable relatively to the other, and one of said members having a plate for coaction with the other member to determine the size of the article to be molded.

2. A mold of the class described having a base provided with an upstanding plate,a body having walls on opposite sides of the ,7 plate, a bar carried by the body outwardly of the plate for the purpose specified, and one of said members being movable relatively to the other.

3. A mold of the class described having a base, a plate rising therefrom, a bodymovable relatively to the base having an end wall, side walls disposed on opposite sides of spacetlierebetween, a body slidable on the base having a partition occupying said space,-

said body having sides engaging the sides of the base, and a cross bar on the body en gaging said plates. V

I 5. A moldof the class described having a base, plates rising therefrom having a space therebetween, a body slidable on the base and consisting of an end member, side members extending below the end members and overlapping the sides of the, base, a partition extending fromthe end member and through said space,'and a bar connecting I said side members and partition and- 1o- I y described compris. mg a baseihavlng upstanding plates with a catedon the opposite side of the plate to the end member.
