JOHN SMITH, OF CALDWELL PRAIRIE, WISCONSIN.
CRANK-PLATE FOR BOLSTER-SPRINGS.
SPECIFICATION forming part of Letters Patent No. 287,335, dated October 23, 1883. Application filed May 9, 1883. (No model.)
To an whom it may concern.-
Be it known that I, JOHN SMITH, of Caldwell Prairie, in the county of Racine, and in the State of WVisconsin, have invented certain new and useful Improvements in Crank-Plates for Bolster-Springs; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to devices for the attachment of bolster-springs in wagons; and it consists in certain peculiarities of construction, as will be particularly set forth hereinafter.
In the drawings, Figure l is a perspective view of a wagon-bolster with its springs attached thereto by means of my device, and Fig. 2 is a like view of the said device alone.
A is a wagon-bolster, and B Bare standards rising from each end.
G O are the springs, and D D are my crankplates, the inner ends of which are bifurcated, and have vertical inner flanges, d d, which receive between them the standards B. These plates are cast with a partly-open horizontal socket, (1, into which is inserted a round wrought-iron rod, which is then bent into the shape shown, forming a double crank, D. The ends of the springs O are then slipped over the ends of the crank-rods D, washers (2 applied, and then the ends of the crank-rods D upset. The crank-plates, withtheir rods and springs attached, can now be slipped down on top of the bolster, the bifurcated ends of the plates receiving the standards, as already stated.
In my drawings I have only shown so much of a wagon as was necessary to illustrate my invention; and it will be understood that bolsters or bed-plates are clipped to the top of the springs G, to supporta wagon-box, or whatever load may be desired to be carried thereby, and that as the weight increases and the springs yield under it they are forced outward, the crank-rods D turning in their sockets, to accommodate the lengthening of the springs, and enable the load to be thereby carried nearer to the axles.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In combination with a wagon-bolster having uprights or standards at each end, the metallic crank-plates D, cast with partly-open horizontal sockets d, and bifurcated inner ends with vertical inner flanges, d d, adapted to re ceive between their bearing-surfaces the bolster-standards, and the double-crank rods D and springs G, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand, on this 17th day of April, 1883, in the presence of two witnesses.
JOHN SMITH.
