vices now in common use have various drawbacks. They may be diflicult to assemble, or their cost may be excessive. In some instances, the device is so constructed that it is ditiicult or impossible to flow or pack the concrete solidly around the dowel adjacent the joint.

it is therefore an object of my invention to provide a transload device which is inexpensive and is easily fabricated by welding the various parts together.

Another object is to provide such a device made of two units which can be easily assembled by telescoping the units together.

Still another object is to provide a transload device which enables the concrete to flow or be packed solidly around the dowel adjacent the joint.

These and other objects will be more apparent after referring to the following specification and attached drawings, in which:

Figure 1 is a perspective view of an expansion joint assembly;

. places.

Figure 2 is a transverse section of the expansion joint of Figure 1;

Figure 3 is an enlarged sectional view of a detail;

Figure 4 is an elevation of a detail;

Figure 4A is a view taken on the line IV-A-IV-A of Figure 4; and

Figure 5 is a view similar to Figure 2, but showing a contraction joint 1.

Referring more particularly to the drawings the reference numeral 2 indicates a pair of concrete slabs having the usual filler member 4 therebetween. My device is made of two complementary units which are telescoped together. Each unit has two longitudinal rods 6 and 8 spaced from the filler 4 and connected by rods 10 and 12 which are welded thereto. Rod 10 is U-shaped with the open end of the U being welded to the lower wire 6 and the closed part of the, u extending above and being welded to the top wire 8, thus providing an opening 14. A dowel 18 extends into the opening 14 and is welded to the rods 8 and 10. The rod 12 has a vertical portion, the lower end of which is welded to the rod 6, and a top portion which formsa clamping device 20. The clamping device, as best shown in Figure 4, is provided with a loop 22 for receiving the free end of the dowel" 18 and a longitudinal portion 24 which extends along the rod 8. The free end of the portion 24 has a book 26 which is adapted to pass below and extend around the rod 8 to a point just below the axis of the rod. The rods 10 and 12 are arranged alternately with the rods 10 of one unit being opposite the rods 12 of the other unit. A plate 28 is welded to each of the dowels 18 on that side of the tiller 4 adjacent the rod 10. The plates 28 are bent at 30 to receive a longitudinal rod 32 which is welded to the plates 28 and extends the length of the joint. As shown in Figure 1, the end of rod 32 is bent toward rod 6 to which it is welded and the end of rod 8 is bent downwardly and welded to the bent portion of rod 32. Holes 34 are provided in the filler 4 for passage of the dowels, the free ends of the dowels having sleeves 36 telescoped thereover. An expansible filler 38 is provided in the sleeve 36 at the outer end thereof.

In assembly, the two units are brought together by passing the free ends of the dowels through the openings 34 into the loops 22. The sleeves 36 and fillers 38 are then applied to the dowels and the hook 26 is moved from the dotted line position of Figure 4 to the full line position, thus locking the two units together with the plates 28 bearing against opposite sides of the tiller 4 to hold it in position while concrete is poured. The plates 28 do not interfere with the flow or packing of the concrete around the dowels adjacent the joint, thus making it possible to provide dense concrete at the most critical The device functions in the usual manner as the concrete slabs 2 expand and contract.

Figure 5 shows my device as applied to a contraction joint. The only differences in the two joints are the omission of the sleeves 36 and filler 38 in the contraction joint and the substitution of a steel separating plateor filler 40 for the expansible filler 4.

While two embodiments of my invention have been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
