ROAD STRIP AND SUPPORT Filed April 25. 1928 Patented Oct. 29, 1929 m andto p UNITED TATES WILLIAM E.

PATENT OFFICE WHITE, OF CHICAGO, ILLINOIS, ASSIGNOR TO KALMAN STEEL COMPANY,

OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE ROAD swan? AND surroa'r My invention relates to concrete roads and particularly to novel means for positioning and supporting a narrow strip constituting a joint in said roadway.

It is customary with some to mount a narrow strip of metal along the line of an expansion joint in the mono ithic roadway and then, after the cementitious material has artially set, to withdraw the strip l zice therein an impregnated felt builders of roads stri Iiiasmuch as the sole purpose of the strip under any circumstances is to provide an expansion joint I have conceived the idea that the desired result may be accomplished with equal facility by utilizing a relatively ve light section of metal extending throug only a portion of the depth of the pavement and allowing the strip to remain in the concrete. This involves certain equipment and the performance of certain essential steps, exam les of which will be disclosed herein.

Suitable stakes or similar supports, in-

tended to become a permanent part of the.

roadway are essential regardless of the type or character of the material of the strip and these stakes must be accurately aligned and positioned under any circumstances. My invention comprises a novel form of stake, strip and fastening clip, the construct-ion of which will be fully described herein.

My invention will. be more readily understood by reference to the accompanying drawings. in which- Fig. 1 is a perspective view of a stake, strip, fastening clip and dowel bar;

Fig. 2 is a side elevation thereof with a bar in section; and

Fig. 3 is a View of a slightly modified form of the invention.

In the drawings, I have illustrated a stake 10 which may be of angular or channel cross section having a head or flat portion 11 that overlies and preferably rests upon the side flanges of the stake. At the sides of the head 11 are right angularly disposed, up-standing lugs 12, spaced apart sufliciently to accommodate the flange 13, of the road strip 14. The latter may be of relatively thin metal portions 14 and 15. The part of the aperture located in the portion 15 acts as a socket or seat for the dowel bar 13 while the part of the aperture 16 in the part 14 cooperates with the lug 12. The cli also has a vertical portion 18 adapted to he against the web 14 of the strip, and a rebent horizontal end 19 adapted to be firmly held between the top of the lug 12 and the web 14. The parts are so dimensioned that when the strip is laid on the head of the stake, the clip may be dropped into lace and by a hammer blow firmly held by iction in the ings. After the ar 17 is positioned as shown the clip cannot escape by upwardmovement and the parts are fully interlocked. In the construction shown in Fig. 3 the stake 20-, strip 21 and strip flange 22 are substantially identical with those already described. However, the lugs 23 on the stake head are provided with oppositely inwardly formed notches 24 near thefibottom of the space between the lugs. These are rovided to accommodate the clip which is 0 Z shape in cross section. It comprises the bottom flange 25 adapted to enter the notches 24, the web portion 26, and the up or flange 27, adapted to abut the web 21. fter the strip and stake have been associated the clip 18 dropped into lace and a hammer blow firmly seats it, there y interlocking the parts and preventing upward movement of the strip relative to the stake.

Other modifications and'variations ma be made in the invention and I do not wis to be limited except as indicated in the appended claims.

I claim: 1. In combination, a relatively narrow elongated stripx having a flange at its lower edge, a'stake aving a head, means on the osition shown in the drawhead for defining a seat to receive the-flange and a cli en aging said seat defining means and sai stnp for retainin the strip and stake against relative vertica movement.

2. In combination, a road strip having a bottomfiange, a stake having a head, In gflojectmg upwardly from the head and eing a space adapted to receive the bottom flange of the strip and a metal clip ada ted to be seated above the flange and to hol the striptand stake against relative vertical movemen 8. In combination, a strip, a stake having a seat, and upwardly projecting lu therefrom between which lugs said strip i: ada ted to be held, a clip adapted to engage sai strip and one of said lugs to hol t e strip and stake against relative vertical movement.

4. In combination, a strip, a stake having a seat, and upwardl projecting lugs therefrom between which ugs said strip is adapted to be held, a clip adapted to engage said strig and one of said lugs to hold the strip an stake against relatlvely vertical movement,- said clip havin an apertured portion adageed to accommo ate a dowel bar passing neath the plane of the seat on the stake.

5. In road construction, in combination a strip of less depth, than the thickness of t e avement, a stake having a head, a pair of u projecting upwardly from the head and de ing a strip receivin recess, a sheet metal clip ada ted to occupy t e space between the stnp an one of said lugs, said clip having an apertured depending portion adapted to receive a transverse dowel bar.

6. In road construction, in combination, a narrow metal strip having a bottom flange, a stake having a flat head provided with upstanding lugs defining a s 'ace therebetween shaped to accommodate t e flan e on said stri a keeper held between'one 0 said lugs an said strip and resting on the flange on said strip sa1d keeper having a depending portion a apted to receive a transverse'bar extending beneath said strip.

' In testimony whereof I have aflixed my signature.

WILLIAM E. WHITE.
