IMPROVEMENT IN RuluNlIxlc-z-GE/msl FOR VEHICLES.

Specification forming part of Letters Patent No. 148,497, dated March l0, 1874; application filed December 3l, 1873.

@Asn C.

To all whom it may concern." f

Be it known that I, GYRUs W. ALADEE, of Pittsburg, in the State of Pennsylvania, have invented certain new Improvements in Gearing for Vehicles, of which the following is a speciiication:

Thev iirst part of my invention consists in bending the front and rear holsters and side perches in one piece, and splicing them together at or about the cross-center of the gearing, in such manner as to make, literally, an endless perch for carriage-gearing.

The second part of my invention consists in supporting and operating two half-elliptic side springs between the two outside perches and upon two separate connecting-rods, the hearings of which latter are also secured to the perches.

Carriage-gearing with two or more perches have a bolster resting upon both the front and rear axles, and in or upon which is secured the opposite ends of the two outside perches, each corner of the gearing presenting two ends, viz., the end of the perch and the end of the holster, to be finished with a scroll, or otherwise, besides involving the cost of bolts and other necessary fastenings to make these connections secure. To obviate all this, I proceed to unite the holsters and side perches as follows, viz: In the first place, I take two pieces of wood of the required thickness and depth for the holsters at their heaviest point, and of a length equal to the length of one bolster and the half-length of each perch. These pieces are now bent into substantially the form shown from H to F of the drawing, and with the round corners S S S S. The opposite ends of these pieces A and Al are then finished up as required, and are spliced together at F and F, after which the side perches A and A are plated with iron, in the usual way. It will now be seen that Ihave produced an endless perch by bending the holsters A with the side perches A, and splicing the latter at or about the erosscenter of the gearing. By this means, I not only get rid of joining the perches A to the ends of the holsters A at S, and the work of inishing the ends of each, as

lis required upon the old plan, but produce a cleaner and smoother inish at these points, and save a great deal of work in the iron connections, otherwise necessary at these points. In-all cases where elliptic springs are to he used over the front and rear axles, they are made to rest upon the ends of the perches or holsters A', between the dotted lines E, but in this case the front holster A will he made considerably shorter than the hind one, so that the rear ends of the perches A will be farther apart than the front ends, and not parallel to each other, as seen in the drawing. If prcferred to bend the perches in one piece, only one splice, F, will he necessary.

I am aware that two perches have been bent in one piece, as shown and described in the patent of John Gurtice, of Cincinnati, Ohio, and in a former patent of my own. In the former case the perches are closed by the bend in front of the head-block over the front aXle, with the rear ends of the perches left open and framed into the hind axle-bed or holster, while in the latter case the perches are closed by the bend in the rear of the hind aXle, and the front ends left open and framed into the head-block over the front axle. But my present invention, let it be well understood, differs materially from both of the forms above described, as well as from all other kinds of bent perches of which I have any knowledge, in this, that both ends of the perches are closed by the bend of the woodmaking the holsters and perches, when completed, in one continuous piece, or, in other terms, an endless perch.

The halfelliptic side springs B and B are linked to two separate connecting-rods, C and C, at D, between the two opposite perches A and A, and the body of the vehicle is then supported upon the center of the springs, in the usual way. rBhe bearings in which the connecting-rods are hung and operate are also secured to the perches, and not to the bolsters, as is the general custom.

Two advantages are attained in this mode of suspending the springs upon and between the perches, viz., first, the springs being suspended zuid operating between the perclies,`

instead of 011 the one side of them, :is is usual, the body can never stri kc the perclies by the over-depression of -the springs; and, second, the perches being on theoutside of the springs, I can attach the steps directly to the perche-s, und not to the springs, as is usual, by which I gain the advantage ot relieving,` the springs of the strain imposed upon them in all cases Where the steps ure secured to either the body or springs, us is 110W the almost universal custom.

I claim as my invention- 1. An endless perch, A and A', substantially as and for the purpose set forth.

2. Connectingods C and C, pivoted at or near the opposite ends of the perehes Aand A, and provided with links D and springs B and B, all combined to operate between the opposite perches A and A, substantially as und for the purpose set forth.
