IMPROVEMENT Ill DRAYS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES S. MARTIN, of Milwaukee, in the connt-y of Milwaukee, vand State of Wisconsin, have invented an improved Dray; and I do hereby declare that the following is a fall, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in Which Figure l is a perspective view; and

Figure 2 is a top view ofthe axle. .I

The same letters are employed in both figures in the indication of the saine parts.

A represents the body of an ordinary two-wheeled dray. B are metallic jaws bolted to the bottom ci' theV dray body. A The vertical 'parallel/jaws are attached to, and project freni, the horizontal plate through which the bolts pass. C is the axle, on which are placed the metallic guides E.l The upper part of the guide-plate sustains a block of India rubber, D, forming the springs. There is a groove in the front and back sides of cach of these pieces E, or a recess formed by tivo parallel projections on cach side, to receive the jaws B', which play vertically in these grooves or recesses with the action of the load upon the springs. G Gr are braces,-tnc upper ends of which are fastened to vthe body of the dray, and the lower ends to the lower part of the vert-ical jaws B. By using this brace thejaws may be made much lighter than they would require to be made WithoutV the braces; and any variation of construction by which this additional strength would be given I regard as the more equivalent of the braces, which I prefer to use rather-than to'increasc the Weight of the castings.

I do not claim the arrangement of parts for the support of the India-rubber'springs independently of the other parts of the dray, for I am aware that similar devices have beencused in tbe application oi' such springs to railroad cars. My invention consists in the production of a new article of mannfactilrc, viz, aldray to which India-rubber springs are applied, substantially as described.` Steel springs have been nscd in the construction of drays; bntithey add greatly to the cost of the dray, and also to its Weight. My improved dray can be built Without adding materially to either the cost of the dray or to its Weight; and I thus produce an improved dray With the advantages belonging to the use of springs, and without addi-ng materially to the heightot` the body of the dray,to its Weight, or cost.' l Y What I claim as my invention, and desire to secure by Letters Patent, is

A dray constructed with springs of India rubber D, placed between the. guide-plates E attached to the axle @Land vertically slidingliavvs B attached belenY the body A, and strengthened by braces G, said parts being combined andarranged substantially as described.

In testimony rvlrereofI have signed my name te this specification in the presence of two subscribing witnesses.
