'NITED STATES GEORGE w. KING, OF REDSTONE, PENNSYLVANIA, ASSIGNOR or ONE-HALF HIS RIGHT TO WILLIAM KING, OF SAME PLACE.

IMPROVEMENT IN KING-BOLTS.

'Specificationforming part of Letters Patent No. 173,797, dated February 22 January. 10, 1876.

To all whom it may concern:

Be it known that I, GEORGE W. KING, of Redstone, in the county of Fayette, in the State of Pennsylvania, have invented a new and useful Improvement in Attachment for Carriages, 8m; and I do hereby declare that attachment for carriages, wagons, &c.; and

consists in pivoting the bolster-plate to the bolsterpin, in combination with a pivoted brace, the latter being connected to the coupling-poles and axle.

To enable others skilled in the art to make and use my invention, 1 will proceed to do,- scribe its construction and operation.

In the accompanying drawings, which form part of my specification, Figure l is a top view or plan of my improvement. Fig.2 is a front elevation of the front axle, bolster, and holster plate. Fig. 3 is an end view of the axle, bolster, bolster-plate, and side view of the coupling-poles and pivoted brace.

In the drawings, A represents the axle,

' which is furnished with a fifth-wheel, B, of

ordinary construction, and a bolster-pin, G, to the upper end of which is pivoted'a bolsterplate, D, at e. f represents the bolster. g represents the coup1ing-po1es,to which is attached 1876 application filed a bar, h, having lugs 71, between which is pivoted the curved end of a brace, J, through the front end of which passes the b0lster-pin G, on the lower end of which is a screw-nut for the purpose of holding the brace J in position with relation to the axle. By this manner of pivotin g the brace with relation to the coupling-pole g and the bolster-pin O, the axle can have its usual movements without destroying the efficiency of the brace J, and, by pivoting the bolster-plate to the upper end of the bolsterpin, the bed of the wagon resting upon the bolster will always retain a horizontal position, notwithstanding the axle may vary from a horizontal plane, as when passing over uueven roads.

It will be seen that the bolsterplate, kingbolt, and brace together constitute a merchautable attachment,,which may be sold for application to vehiclesalready constructed.

WhatI claim as of my invention is- The' combination of the bolster f, the kingbolt pivoted thereto at its upper end and passing throngh the axle A, and the brace J pivoted below the pole g and connected to the lower end of the. king-bolt, substantially as set forth. I

GEORGE W. KING.
