IMPROVEMENT IN RUBBER SPRINGS FOR WAGONS.

Specification forming part of Letters Patent No. 51,697,

To all whom it may concern Be it known that I, SAMUEL G. OLoUGH, of the villageofVVaupun, county ofDodge, State of Wisconsin, have invented a new Method of Attaching or Applying Rubber Springs to \Vagons; and Ido declare thatthe following is a full and exact description thereof, reference being bad to the accompanying drawings,and to letters of reference marked thereon, in

. whichtaching two sets of cast-iron cups to the hind axle and bolster of a wagon in such manner as to receive rubber springs, on which pistons are placed, which are attached to the crossbar above the bolster, and which supports the box or load; also, in using two cups for the forward axle,which is made in such a manner as to hold the spring, answer the purpose of bolster-plates, and keep out the dirt and gravel. Thus it will be seen that good durable springs are easily and permanently applied to a lumberwagon.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my wagon in any of the wellknown forms, and apply or attach myimprovement thereto in the following manner: On each side of the hind bolster, L, and axle M I attach two cups, E E, Fig. 1, in which I place rubber springs. On these springs press a double piston, F F, Fig. l,whichisconnected to the cross-bar G, that sustains the load. It will be seen, Fig. 1, that these cups have flanges a fitted to them, through which bolts b pass, that fasten them to the bolster and axleof the wagon, thereby a-fl'ordinga durable mode of attaching them thereto and to each other.

Another important object is accomplished by my mode of attachmentviz.,thestrengthening of the axle by connecting it with the dated December :26, 1865.

bolster by means of the bolts and flanges on the cups. In my arrangement I do not use a rubber spring thinking it to be new or its application to lumbefiwagons as new, butsimply from the fact of its beinga good elastic spring. Neither do I use the cups thinking them to be new, nor could Iwithout adapting them to the specific purpose; but to do this they need to be changed so as to conform to the sides of the bolster and axle on which they are placed and afford ready means of attaching them thereto. To accomplish thisI causeafiange, a, to be made soas to project below the bottom and from-each side ofthe cup, so as to permit bolts v to pass through them to confine them to the bolster and axle. These bolts, passing through the flange on one side of the bolster and axle,

then through the bolsterand axle, and then through the flange on the other side, are confined by means ofa head and nut in the ordinary manner. Between the front bolster and sand-board I insert another spring by means of two cups, as shown, Fig. 1, H I. These cups serve the purpose of bolster-plates and take their place when applied. To preventthe dirt and sand from falling into these front cups I make the upper one to project down over the lower one, as seen in Fig. 3, the rubber being contained in both cups.

I am aware that rubber springs have been applied to lumber-wagons by means of clasps passing below the hind axle and pins passing through the axle and bolster communicating with the cross-bar. There are serious objections to this mode of-application. The clasp passing below the axle, by obstructions and broken. Another objection is that the passing of the pin through the axle and bolster tends to weaken them, making them liable to be broken when heavily loaded.

It will be seen by my arrangements that the above objections are fully obviated and instead of diminishing the strength of the bolster and axle by connecting them together, I greatly increase their strength and durability.

I am aware, also, that springs have been applied to the forward bolster and axle by means ofa cup cut into and placed upon the axle, completely cutting into the sand-board and it is liable to be caught deeply into the axle. There are objections to l \Vhat I claim as my invention, and desire this mode of application, among which is the l to secure by Letters Patent of the United cutting into of the sand-board, cutting into i States, is-
