T all wbOm/ may COHOSWL: lper ends of these rods are connected by ilat Be it known that I, PHILIP L. RAMsEY, a plates F. Beneath these plates are arranged citizenof the United States, residing at Schomovable plates M, having eyes in their ends choh, in the county of Logan and State of which slide upon said vertical rods, and on '5- 5 Kentucky, have invented a new and useful thelatterarearranged strong expansivecoiled Vehicle-Spring Gear, of which the following springs S, which rest at their lower ends upon is a specification. the perch (the front one resting upon a washer This invention relates to carriages and waglV above the upper eye c' of the U-shaped ons, andmore especially to the springs thereof; arm U) and bear at their upper ends beneath 6o ro and the object of the same is to produce an the plates M. The latter are provided at their improved arrangement of springs, whereby centers with depending eyes t', in which are the wagon or carriage body will be firmly suphung the centers of yokes Y, whose arms exported, but yet permitted a greater degree of tend thence downwardly and outwardly, as motion than formerly, over rough roads. shown. 6 To this end the invention consists of the de- Secured to the bottom of the body at its tails of construction hereinafter more fully four corners are straps which extend outdescribed and claimed, and as illustrated on Wardly and form ears E, and these ears are the accompanying sheet of drawings, whereconnected across the ends of the body by horiin zontal rods H, and to these ears are also con- 7o 2o Figure l is a general perspective view of a nected the lower ends of the yokes Y.

Vhen one wheel passes over with the U-shaped arm on the king-bolt K, as an obstruction, as seen in Fig. 3, one end of is desirable in ordinary travel. the axle will be raised, which will throw the At the ends of the perch P are arranged rods V out of a vertical position; but as the vertical rods V in pairs, the front rod of the upper ends of these rods are connected by Ico 5o front pair preferably being a continuation of the yoke Y with the body it is obvious that` the king-bolt K, above described, and the upthe centers of these rods must move longi-l tudinally of the horizontal rods II. This movement is permitted by the springs S', and at the same time the cushioning effect of the vertical springs is not interrupted. Hence the body B will always stand level, even though one wheel may pass over an obstruction nearly or quite a foot in height. p

I do not limit myself to the exact details of construction shown and described inI this application, as considerable change may be made therein without departing from the spirit of my invention. For instance, the speciic means by which I pivot the front axle so as to permit its vertical as well as its horizontal motion may be useful by a slight adaptation of parts in other connections, although I prefer to employ it here, and the rubber buf` fers or washers R, which I should have said are employed at each end of each of the springs, might be omitted, although their use causes the device to be practically noiseless.

What is claimed as new is-` 1. In a device of the character described, the combination, with the perch having a bifurcated front end, an eye pivoted therein on the king-bolt and having a forwardly-extending shank, and a U-shaped arm having eyes at its rear end pivotally mounted on said kin g-bolt above and below the perch, the front end of said shank being connected with the bend of the arm, of the front axle extending through said arm and pivotally mounted on the shank, as and for the purpose set forth.

2. In a device of the character described, the combination, with the perch, vertical rods rising therefrom in pairs and connected by plates at their upper ends, and the body standing between said pairs, of coiled springs on said rods, moving plates above their upper ends belowthe connectingplates, eyes depending from the centers of the moving plates, and yokes connected at their centers to said eyes and at their lower ends to the corners of the body, as and for the purpose set forth.

3. In a device of the character described, the combination, with the perch, vertical rods rising therefrom in pairs and connected by flat plates at their upper ends, moving plates having eyes loosely mounted on said rods, a coiled spring between the perch and each moving plate and upon each rod, a depending eye at the center of each plate, and vertical guides rising from the perch between the lower ends of each pair of rods, of a body mounted between said pairs of rods, ears at the four corners of said body, horizontal rods connecting said ears at the ends of the body and passing through said guides, a yoke at each end of the body connected at its ends to said ears and at its center to said depending eye, washers on said horizontal rods at each side of each guide, and a coiled expansive spring between each washer and eye on the horizontal rods, all as and for the purpose set forth.

4t. In a device of the character described, the combination, with the perch, vertical guides rising therefrom, a body between said guides, and springs, substantialy as described, for cushioning the vertical movement of the body, of ears at the four corners of the body, horizontal rods connecting said ears in pairs across the ends of the body and extending through said guides, washers on said rods adjacent the guides, and a coiled expansive spring on said rod between each washer and eye, as and for the purpose set forth.

5. In a device of the character described, the combination, with a perch having a bifurcated front end, a king-bolt passing therethrough and rising vertically therefrom in front of the wagon-body, an eye pivoted in said bifurcation upon the king-bolt and having a forwardly-extending shank, a U shaped arm having eyes at its forward ends pivotally mounted on the king-bolt above and below therperch, the front end of said shank being connected with the bend of the arm, and the front axle extending through said arm and pivotally mounted on the shank, of a moving plate upon said king-bolt, an expansive springbetween the upper eye of said U-shaped arm and said moving plate, and connection between the latter and the wagon-body, all as and for the purpose set forth.

6. In a device of the character described, the combination, with the perch, vertical rods rising therefrom in front and in rear of the body, moving plates mounted loosely on said rods, and springs between said plates and perch, of connections, substantially as described, between said plates and body, as and for the purpose set forth.

7. In a device of the character described, the combination, with the perch, vertical rods rising therefrom in front and in rear of the body, moving plates mounted loosely on said rods, springs between said plates and perch, and vertical guides-rising from the latter, of ears at the corners of the body, connections between said ears and plates, and expansive springs between said guides and ears, all substantially as and for the purpose hereinbefore set forth.

In testimony that I claim theforegoing as my own I have hereto affixed my signature in presence of two witnesses.

. PHILIP L. RAMSEY.
