A dowel 16 extends 3 38 in the contraction joint and the substitution of a steel separating plate or filler 40 for the expansible filler 4.

Figures 6 and 8 show a slight modification of my device as applied to an expansion joint. In this embodiment a pair of concrete slabs 42 have the usual filler member M therebetween. Two complementary units are provided which telescope together to form a complete device. One

unit 46 is essentially the same as the units of the first described device, the only difference being that plates 48 are substituted for plates 28 and an additional longitudinal rod 50 is welded thereto. The rod 50 extends the length of the joint, the plates 48 being bent at 52 to receive the longitudinal rod 50. The second unit St has the same outboard supports as the first embodiment. However, in place of the plates 28 and longitudinal rod 32, a continuous plate 56 is provided which extends the length of the joint. This plate 56 is provided with corrugations or head formations 58 at the top thereof to provide a stiffening effect. Alternate dowels i8. are welded to the plate 56 at the points 60 with holes 62 being provided in the plate between the points 60 for slidably receiving the remaining dowels. A removable joint shield 64 is provided over the filler member 44 as shown. The operation of this device is essentially the same as that of the first embodiment.

Figures 7 and 8 show the device of Figure 6 as applied to a contraction joint. The only differences in the two joints are the omission of the sleeves 36 and the filler M from the contraction joint.

Figures 9 through 12 show a further modification of my device as applied to a contraction joint. In this embodiment two complementary units are provided which telescope together to form a complete device. two longitudinal outboard rods 66 and 68 connected in spaced apart relationship by rods 10 and I2. Rods 10 are U-shaped with the open end of the U being welded to the lower wire 56 and the closed part of the U extending above and being welded to the top wire 88, thus providinto each opening-I4 and is welded to the rods 68 and/or 10. The rod 12 has a vertical portion, the lower end of which is welded to the rod 66 and a top portion which forms a clamping device 18 which is identical to the clamping device 20. Each of the dowels of the right hand unit 80 as shown in Figure 12 has a washer or stop member 82 welded thereto substantially on the transverse.

center line thereof. -Thedowels of the left hand unit M are welded'to the contraction joint plate 86 intermediate their length. Plate 86 is'provided with a bead formation 88 to give lengtha The plate 86 extends from.

wise rigidity thereto. a point below the-dowels 16 to a point approximately one-half inch below the top of the concrete slab 90. Truss wires 92 may be fastened to theends of the longitudinal wires 66 and to the bottom of plate 86 to provide stability for ship-.

ping and handling. Similar truss wires may also be used in the embodiment of Figures 6 to 8. When the concrete slab 98 contracts, a crack 93 will form therein below the plate 86, thus forming two slabs.

a While several embodiments of my invention have been shown and described, it will be apparent that other adaptations andmodifications may be made without departing from the scope of the following claims,

Each of the units has I claim:

1. In a transload device for adjacent slabs, the combination including two telescoping supporting units; each unit comprising a pair of outboard longitudinal rods spaced apart one above the other, spaced apart U-shaped rods having their open ends welded to the lower rod and their closed ends welded to the upper rod and extending thereabove to form an opening, a dowel pass= ing through each opening and welded to the sur-' rounding rod, a clamping rod between adjacent pairs of said U-shaped rods extending between and welded to the bottom and top longitudinal rods, each of said clamping rods extending above the top longitudinal rod and having a loop for receiving a dowel of the opposite unit, each of said clamping rods extending from said loop along said top longitudinal rod and having a hook portion at the free end adapted to pass below and around the top longitudinal rod, one of said units having a vertical plate welded to the dowels thereof intermediate the length thereof and extending therebetween, said vertical plate having spaced holes therein one for each of the dowels of the other unit. I 2. In a transload device rounding rod, a clamping rod between adjacent pairs of said U-shaped rods extending between and welded to the bottom and top longitudinal rods, each of said clamping rods extending above the top longitudinalrod and having a loop for receiving a dowel of the opposite unit, each of said clamping rods extending from said loop along said top longitudinal rod and having a hook portion at the free and around the top longitudinal rod,

end adapted to pass below one of said units having a vertical plate welded to the dowels thereof intermediate the length thereof and extending therebetween, said vertical plate having spaced holes'therein one for each of thedowels of the other unit. each of the dowels of said other unit having a collar rigidly fastened thereto intermediate its length adapted to bear against said plate.

,3. In a transload device for adjacent slabs,

"the combination including two telescoping supporting units; each unit comprising a pair of outboard longitudinal rods spaced one above the other, means connecting the longitudinal rods in spaced relationship, dowels rigidly fastened to the top longitudinal rod at spaced intervals, a clamping rod between adjacent pairs of dowels extending between and welded to the bottom and top longitudinalrods, each of said clamping rods extending above the top longitudinal rod and having a loop for receiving a dowel of the opposite unit, each of said clamping rods extending from said loop along said top longitudinal rod and having a hook portion atthe free-end adapted to pass-below and around the top longitudinal rod, one of said units having a vertical plate welded to the dowels thereof intermediate the length thereof and extending'th'erebetween, said vertical plate having spaced holes therein one for each of the dowels of the other unit. a

4. In a transload device for adjacent slabs, the combination including two telescoping supporting units; each unit comprising a pair of outboard longitudinal rods spaced one above the other, means connecting the longitudinal rods in spaced relationship, dowels rigidly fastened to the top longitudinal rod at spaced intervals, a clamping rod between adjacent pairs of dowels extending between and welded to the bottom and top longitudinal rods, each of said clamping rods extending above the top longitudinal rod and having a loop for receiving a dowel of the opposite unit, each of said clamping rods extending from said loop along said top longitudinal rod and having a hook portion at the free end adapted to pass below and around the top longitudinal rod, one of said units having a vertical plate welded to the dowels thereof intermediate the length thereof and extending therebetween, said vertical plate having spaced holes therein one for each of the dowels of the other unit, each of the dowels of said other unit having a collar rigidly fastened thereto intermediate its length adapted to bear against said plate.
