VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 500,515, dated June 27, 1893.

Application filed October 3, 1892. Serial No. 4 18339. (No model.)

To all whom it may concern:

Be it known that I, EZRA B. SMITH, a citizen of the United States of America, and a resident of the city of Cincinnati, in the county of Hamilton and State of-Ohio,have invented certain new and useful Improvements in Vehicle-Springs for Road-Vehicles,of which the following is a specification.

My invention is more particularly adapted [O for buggies and light road wagons.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims. In the accompanying drawings making a part of this specification, and to which reference is hereby made,Figure l is a plan view of a vehicle gear illustrating one application of my invention. Fig. 2 is a view of the front end of said gear. Fig. 3 is a view in perspective of a coupling constructed according to my invention, the adjacent end of the spring which this coupling is designed to unite being broken away and indicated by dotted lines, in order to enable my coupling the better to be seen. Fig. 4 is a view partly in section,of the device shown in Fig. 3, the section being a vertical transverse one and taken in the direction of the dotted line 4 of Fig. 3. Fig. 5, sheet 2, is a vertical, central transverse section of the devices shown in Fig. 4, and taken at right angles to the section shown in Fig. 4, the lower cross bolt in elevation. Fig. 6 is a plan in perspective of a modified form of my coupling. Fig. 7 is a plan view of a second kind of vehicle gear to which certain features of my inventionare applied. Fig. 8 is a vertical, central section of a front axle, fifth wheel and braces, taken in the plane of the dotted line 8 of Fig. 7. Fig. 9 is a vertical central section of the coupling shown in Fig. 6, and taken in the plane of the dotted line 9 of Fig. 6. Certain parts of this figure are, obviously, in elevation.

My invention in general consists of a novel and exceedingly useful means of uniting the adjacent ends of springs located at an angle to one another.

The invention allows one to make three styles of gear from one.

I will now proceed to specify the invention in detail.

A indicates a clip piece having back A, and downwardly extending ends A A each of said ends having the screw threaded extensions A The distance between the inner portions of the ends A is equal to or slightly in excess of the breadth of the terminal portion of the spring to which it is to be fitted. 0n the under side of the back A is a teat or other projection A whose function will be hereinafter described.

Opposite to and beneath the piece A is a piece B having centrally a semicircular recess or depression B running at right angles to the length of the piece A. Each end B of this piece 13 extends under the adjacent end A of piece A and has a vertical opening 13 through which the threaded extension A of said piece A may pass. To return to the recess B. The bottom portion B of the interior of this recess (see Fig. 5) is not flat, but curved convexly, being higher in the midlength of the recess and lower at each end.

C indicates aswinging shackle of the usual and well known form, but of such width between its arms 0 C that its main or body portion C may enter the recess B, and rest upon the bottom B thereof, while the arms C C snugly fit against the ends of the portion B, but not so tightly as to prevent them from freely oscillating. The bottom side of %he main portion may be curved as shown in The mode in which this device as thus far described is applied in connecting two springs is as follows :-In the end portion of a spring, as for instance, the front cross spring S, is formed an opening or recess S If this be a recess, and not a hole extending through the spring, it is located in the upper side of the end portion of the spring. The piece A is now laid on the end of the spring, the latter being located between the ends A A of the piece. The teat A projects into the recess S of the spring. The piece 13 holding the swinging shackle C is now applied to the under side of the spring and directly beneath the piece A. The extended screw threaded portions A A of the piece A respectively pass through the openings B B of the ends B 13 of the piece B, and project below the latter. Upon these projecting portions of thepieces A A are respectively screwed their respective nuts A A The effect of this last operation is to firmly clamp the end of the spring between the pieces A and B, and firmly attach these together with the swinging link to the spring. The end of a side spring as S having the well known eye E, is now attached to the swinging shackle O by the usual bolt C passed first through one arm 0 of the shackle, then through the eye E of the shackle, and then through the other arm 0 of the shackle, and then secured in place by a nut C. To the other end of the front cross spring S is connected a device like the device A, B, O, and the mode of connecting the device to the spring end is also similar. To the shackle of this seconddevice is connected the other or opposite side spring S of the vehicle.

The rear end of each side spring S may be connected to the adjacent end of a rear cross spring by a device A, B, 0, like that described. But the rear ends of said side springs are preferably connected to the ends of the rear cross spring by the following device, viz: The upper portion A is exactly similar to the portion heretofore described, but the under portion and the shackle are in one piece, substantially as shown in Figs. 6 and 9, that is to say, the main or body portion 0 of the shackle is made in one piece with the end portions B B and with the body B of the piece B, the recess in the body portion B being omitted as unnecessaryin this form of device. The end of the spring S is inserted between the body A of the piece A and the combined portion 0, B, B already described. The teat A of the, piece A enters the recess S in the spring S, and the bolts A pass through the respective ends B B and receive the nuts A A as aforementioned. This end of the springS is thus held firmly in place, while the spring S being connected to the arms 0 C by the bolt 0, as aforementioned, holds the end of the spring securely in position. Such a construction of course prevents the shackle from swinging, but if the front connecting devices have swinging shackles, as shown, these latter will ordinarily be quite snflicient to accommodate the elongation of the spring.

It is obvious that my coupling devices are exceedingly compact and enable the cross springs to be connected to the side springs veryclosely and without a large amount of intervening material of a complicated nature built in between the adjacent ends of the two springs in order to unite them.

The Brewster side bar gear is one quite popular, at times, and consists, as is well known, of side bars connected at their respective ends to the adjacent ends of the front and rear cross springs as S, S. It frequently becomes desirable to change said gear by substituting side springs for the said side bars.

. tially as shown in Fig. 1.

By means of my invention, this substitution can be very easily and quickly accomplished and the springs S, S, will take the place of the said bars and be connected as already described and as shown, and will be arranged in connection with the rear cross bar, substan- Of course, the gear may, in the first instance, be made as shown in Fig. 1. In such gear,Lrepresents the front axle, M the rear axle, and N a well known form of fifth wheel. The particular construction of the fifth wheel is not material to my invention. Beneath the front cross spring S and the said fifth wheel N is the usual bolster K.

P, P, represent the divergent perches and P, P, the brace respectively connected at one end to the perches at or near the center, and, at the other ends, to the rear axle respectively nearer to the wheel than the points where the said perches are connected to the axle.

R, R, represent customary braces extending from one side spring S to the other side spring S, and forming supports forthe body of the vehicle. Such gear is well known and is what is known as a rigid gear.

My invention is applicable to a platform spring, which has in it the arrangement of front and rear cross springs S, S, united to the side springs S, S, substantiallyasshown in Fig. 7. In such event, the cross springs will be connected to the rear axle, as shown in Figs. 1 and 7, by means of the brace D, consisting of the straight portion D extending from one side spring S to the other side spring S, and attached to each spring by a suitable clip D or equivalent connection. At the straight or body portion D of the brace are the arms D These arms extend backward and the rear end of each arm is connected substantially as shown, to the rear axle by a clip as D, or equivalent device. The front axle L is connected to the side springs S, S, by means of a central spring I, centrally connected to the axle preferably at a point underneath the same, substantially as shown in Fig. 8 and extending backward and upward to a cross bar J, which latter is fastened to the side springs S, S,.at or near its end by a clip or equivalent device J, J, substantially as shown. This spring I is made of spring steel and the elasticity. thereof is best utilized by curving the rear end of the spring under and then up behind the cross bar Jand then bringing theend of the brace I over the top of the cross bar J and there bolting it at J to the said cross bar. By this last described gear freedom of the side springs S, S, to elongate as they are depressed by a load or vertical thrust, is given without the necessity of a swinging shackle connection, for the reason that the rear and front axles are permitted to separate the distance the side springs elongate.

description of gear, the devices for connecting the ends of the side springs S, S, to the Consequently, in this cross springs S, S, are preferably of the kind illustrated inFigs. 6 and 9.
