WAGON-GEARING.

SPECIFICATION forming part of Letters Patent No. 338,876, dated March 30, 1886. Application filed January 4, 1886. Serial No. 187,592. (No model.)

To aZZ whom it may concern:

Be it known that I, PETER J. RICHTER, a citizen of the United States, residing in Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in lVagonGearing, of which the following is a specification.

My invention consists in devices for attaching the forward axle t0 the bolster, and in the combination, arrangement,and construction of the several parts comprising the gearing, as I hereinafter more fully describe and claim; and the object of my invention is to reduce the cost of manufacturing wagons and to provide a device by means of which one spring only will be necessary to give the body the proper vertical movement, and by which the weight of the body and load is to a great extent supported independently of the spring, so that a much lighter and more sensitivespring may be used, whereby the weight of the wagon is greatly reduced. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of myimprovement detached from the body and wheels. Fig. 2 is a side view of a wagon, partly sectional, containing my improvement. Fig. 3 is adetached plan view of the spring. Fig. 4 is a View of a portion of the rear axle and the truss-tie. Fig. 5 is a view of the under side of the truss-tie. Fig. 6 isafront view of the front axle and section of thills. Fig. 7 is a side view of the thill attachment. Fig. Sis a longitudinal vertical section of the bolster attachment. Fig. 9 is a transverse vertical section of the same.

Similarletters refer to similar parts throughout the several views.

a represents the body of a wagon, and a the seat.

I) is the rear axle, and I) is the front axle, each of which has its central portions curved upward, and is strengthened by a trusstie rod, 0 and c, which is secured by its ends to the axle by the bolt (Z, and also by the clips d.

e is a bolster pivoted in its center to the front axle, and to the ends of the bolster are rigidly secured the levers f. These levers f are pivoted near their central portion to the lower end of the supports while the upper ends of the supports are rigidly secured to the under side of the body a. The inner ends of these levers fare turned upward in a suitable position, so that the upturned ends will be located beneath the seat a, where they are firmly secured to the opposite ends of a spring-bar, h. Similar levers, f, are secured to the rear axle and pivoted to the supports 9, and have their inner upturned ends secured to the ends of the springbar h, which is located at a short distance in rear of the bar h, so that a spring, i, may be placed between and secured to the central portion of the bars h and h. This springz' is composed of two portions curved in opposite directions, and their ends are secured together by an open link, i, passing loosely through holes in the ends of the half-springs, and having in its central portion a solid collar, j, against which each portion of the spring bears and which admits of a free winding movement of the parts of the spring when necessary. The levers are also provided with suitable side braces, which serve to hold them in a rigid position in relation to the axle and bolster. The operation of this arrangement is that the body a and its load are carried by the levers f and f, the supports 9 and 9 being attached thereto 1'11 such a position as to leave the outer ends of the levers considerably shorter than the inner upturned ends, which gives the springa great advantage and allows a much lighter spring to be used,while the wheel rising over an obstruction or inequality of the road acts to move the lever to the required distance without greatly moving the body,and the recoil of the spring upon the long arm of the lever acts to bring the levers gently to their former position without a sudden recoil, as in the vertical springs usually used.

Secured to the under side and in the center of the bolster e by the bolts e is the bolsterplate It. The under side of this plate It is circular in form and is provided with a recess, It, into which is fitted the upper portion, Z, of a box, it, which surrounds the front axle, b. The lower portion, Z, of this box it is secured to the upper part, Z, by the bolts m, and a chamber, a, is arranged in the central portion of the parts Z and Z to receive a collar, n, which is welded to the axle in the middle of its length, and which prevents an end movement of the axle in the box, and also permits the axle to revolve within the box. A king-bolt, 0, passes from the chamber a through the partl and through the bolster-plate and bolster e, securing the parts together and allowing the partl to turn within the recess 70'. In order to give greater strength to this connection of the parts, I secure by the bolts m, beneath the part Z, a clip, 0, which is provided at a point directly opposite the king-bolt 0 with a stud, p, to which is secured the lower part of the braces p,while the upper portion of the braces are secured to the upper end of the king-bolt above the bolster.

The thills r are secured in position to the axle b rigidly by the usual thill-iron, 0*, provided at its lower end with a T-extension, which rests upon and is held to the axle by the clips d and the bolt (1, the clips and bolt passing through side lugs on the truss-rod as well. This rigid attachment of the ihills to the axle causes the axle to turn in the box it when the thills are raised up or lowered, and is easily constructed and avoids all looseness and noise caused by the usual mode of attachment, besides being stronger and more durable.

Suitable holes are provided in the levers f and f, with which the proper weight may be brought to bear upon the spring z, as by moving the supports 9 and g to a point nearer the outer ends of the levers a greater portion of the load is carried by the axles, the fulcrum being changed to lengthen the inner arms of the levers, and thereby giving the spring a greater advantage.

"What I claim as my invention, and desire to secure by Letters Patent, is

1. In a wagon-gearing, the levers f, secured by their outer ends to the bolster and by their inner upturned ends to the spring'bar h, the levers f, secured by their rear ends to the rear axle and by their inner upturnedends to the spring-bar h, the supports 9 and g, secured to the body by one end and pivoted to the levers f andf by their opposite ends, and the spring 12, secured between the bars h and h, in combination with an open link, '5, passed through openings inthe ends of the springsections, and having a solid collar,j, upon its PETER J.
