'5 Claims. (or 94-18) This invention relates to certain new and useful improvements in expansion joints. I The primary object of the invention is to provide an expansion joint of the character employed in the laying of roads to compensate for expansion-and contraction of the material comprising the road so that such expansion and contraction may take place without resulting in cracks or fis- Figure 1 is a top plan 'view of an expansion" joint for hard roads, the joint being constructed of sections and extending the full width of the Figure 2 is a bottom plan view of the expansion joint;

Figure 5 is a cross-sectional view taken on line 5-5 of Figure 3 showing the parts embedded in adjacent pavement sections;
Figure 6 is a cross-sectional view taken on line adjacent pavement sections.
The expansion joint disclosed herein is designed for use in the construction of roads so that the material of the roads may expand and con-' tract with damage to the roads eliminated, the expansion joints being positioned certain distances apart to compensate for expansion of the road materials. The expansion joint comprises a pair of spaced angle members extending the full width of the road, each angle member comprising a vertical wall carrying an outwardly directed horizontal wall II at its upper edge with the outer edge of the wall ll flanged upwardly as at l2. The walls In are spaced from each other as illustrated in Figures Wand-6 while the horizontal walls I l disposed in the same plane provide a seat for the tread plate l3 that has a roughened surface l3a as shown in Figure lcomprising diamond-shaped formations to prevent skidding, the tread plate being loosely mounted upon the horizontal walls H. The tread plates iii are formed in sections and as illustrated in Figure 1, they extend the full width of the road bed.
A channel iron I4 is positioned between the 55 upper ends of the walls ll of the angle members 6-45 ofFigure 3 showing the parts embedded in I and the several tread'plates l3 are secured thereto in any preferred manner, the closed side of the channel iron I4 having the tread plate secured thereto with the open side thereof directed downwardly for the reception of the cross-head l5 of the depending T-iron IS. The T-iron constitutes a part of guidedevices for movement of the angle irons comprising the walls Ill and ll, the T-irons having spaced openings il therein for the passage of rods It that also extend through aligned openings 19- provided in the walls Ill. The-outer ends of the rod l8 are received in sleeve members 20 embedded in the road material while coil springs 2| surrounding the rod I8 between the T-iron l6 and walls l0 maintain the walls ID of the angle irons properly positioned relative to the material of the road bed. Tie rods 22 are secured as at 23 to the walls ID of .the angle irons and are embedded in the road. As shown in Figures '1 to 4, an end wall 24 is hinged as at 25 to' the outer ends of the end tread plate l3 to provide closures for the ends of the expansion jointan'd are retained in closed position by bolt and nut devices 26 forming connection between the end wall 24' and the T-iron l6.
From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it
being noted that the angle members comprising the wallslil and II are shiftable during expansion andcontraction of the road material, moving under the tread plates l3 and guided in their movements on the rods l8, the spring devices 2| serving to correctly position and hold in proper position the plates l3- at all times with respect to the angle members Ill as they are moved back and forth due to the contraction and ex-' pension of the road material.
While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
I claim: 1. An expansion joint for pavements to be located between adjacent pavement sections comchannel iron connected with the bottom of the tread plate, a T-iron connected with said channel iron and projecting down between the angle members and a rod extending through the angle members and the T-iron, and opposing spring members mounted between the vertical flanges of the angles and the stem of T-iron to hold the latter in operative position.
2. An expansion joint for roads, comprising separated adjacent pavement sections, a pair of angle members inserted in the road bed between the adjacent pavement sections and crosswise of the pavement, means for holding said members in correct position with relationto said adjacent pavement sections and shiftable during expansion and contraction of the, road bed, a tread plate loosely mounted on top of the angle members, a downwardly projecting member connected with said tread plate and projecting becent pavement sections and crosswise of the pavement, springs mounted between said members, a rod extending through said members and said springs, and guiding devices mounted in the separated adjacent pavement sections into which the ends of said rod are received, said rod holding said shiftable members in proper vertical relationship but free to move horizontally with respect to said shiftable members, whereby the 40 various elements cooperate with the separated adjacent pavement sections to compensate for expansion and contraction due to variations in temperature.
4. An expansion joint for roads, comprising separated adjacent pavement sections, a pair of shiftable members in spaced relation, adapted to be inserted in the roadway between the adjacent pavement sections and crosswise/of the pavement, springs mounted between said members, a rod extending through said members and said springs, and guiding devices mounted in the roadway into which the ends of said rod are received, a tread plate mounted on said members, said rod holding said shiftable members in proper vertical relationship but free to move horizontally with respect to said shiftable members, whereby the various elements cooperate with the separated adjacent pavement sections to compensate for expansion and contraction due to variations in temperature. a
