DOUBLE-ENDER SLEIGH RUNNER.

SPECIFICATION forming part of Letters Patent No. 716,543, dated December 23, 1902.

Application filed June 21, 1901. Serial No. 65,497. (No model.)

.[b all whom it may concern.-

Be it known that 1, JOHN E.HOBBs, of North Berwick, in the State of Maine, have invented certain new and useful Improvements in Double-Ender Sleigh-Runners, whereof the following is a specification, reference being had to the accompanying drawings.

My present improvements are particularly applicable to runners arranged to be detachably secured to the body of a sleigh, pung, or wheel-vehicle.

As hereinafter described, my invention comprises a unitary framework independent of the vehicle-body to which it may be attached and consisting of a pair of counterpart runners having upwardly-curved ends connected by cross-bars rigidly braced to the respective runners.

In the accompanying drawings, Figure 1 is a side view of a vehicle-body provided with a runner-framework conveniently embodying my improvements. Fig. 2 is a plan view of the sleigh-runner shown in Fig. 1. a rear elevation of the runner shown in Figs. 1 and 2. Fig. at is a side View showing in detail the peculiar construction of the runner side springs.

In said figures, A A are counterpart runners, which are connected at their front extremities by the cross-bar B and at their rear extremities by the cross-bar 0. Each of said runners A comprises a wooden base-bar A, whose opposite ends a are upwardly curved, as best shown in Fig. 1. Each of said basebars A is provided with a shoe A of iron or steel, the extremities a of which project beyond the curved ends a of the base-bar and are respectively secured to the cross-bars B and O. Said cross-bars B and O are rigidly secured to the base-bars A by the trusses D, which are fixed at their crowns d to said crossbars and provided with downwardly-divergent limbs d, fixed upon said base bars. Each of said trusses D is braced by standards D the feet 61 of which are fixed upon the respective base bars A intermediate of the limbs d of the trusses. Said standards are secured to the limbs d of the trusses at d intermediate of their height and extend laterally beneath the respective cross-bars B C, to which they are secured at d. The proximal limbs d of the trusses D upon the respective base-bars A are connected by respective tie-bars E, which are secured to said limbs d at (Z and said tie-bars E are connected with the base-bars intermediate of their length by means of the brackets e. The springs E, which connect the cross-bars parallel with the base bars A, preferably comprise several leaves arched, as shown in Fig. 1, the respec tive leaves f of said springs B being extended beneath the respective cross-bars B O and upturned and recurved, so as to overhang said cross-bars. The overhanging ends of said springs F are mounted upon bearing-plates b 0 upon the respective cross-bars B O, to which they are secured by the clip-bolts b c, which preferably extend across the ends of the springs diagonally, as best shown in Fig. 2, so as to distribute the strain upon each spring. The downwardly-turned ends f of said springs F engage the inner edges of said cross-bars B C, as best shown in Fig. 4, and I prevent longitudinal displacement of the springs. The cross-bar O terminates laterally at the outer faces of the opposed runners A; but the ends of the front cross-bar B proj ect laterally beyond the runners A and are provided with couplings B to engage the thills H, so that said bar B constitutes the draft-bar of the unitary structure above described,which is so constructed and arranged as to be self-supporting independently of any vehicle-body. However, any preferred form of vehicle-body I may be conveniently mounted upon the yokes G, which are secured upon the springs F by the clip-bolts g, as indicated in Fig. 1, such body being secured to the yokes by any convenient means, such as screws or bolts.

The structure above described is so arranged that the weight of the body I and its contents is distributed by the springs F to the cross-bars B and O in such manner as to tend to separate said cross-bars in the direction of the length of the runners, and said runners are braced against the strain thus produced by the arrangement of the trusses D,with the downwardly-divergent limbs fixed upon the base-bars A. The tie-bars E also serve to brace the trusses D against displacement in the direction of the strain placed upon them by said springs and tend to stiffen the base-bars A.

It is to be noted that the construction and arrangement of the parts above described are such as to secure the maximum strength of the runners without interference with the light and graceful appearance of the latter. Moreover, although the base-bars A, braced and connected as above described, form a very rigid and substantial base for a vehicle the superimposed springs and parts connected therewith are so arranged as to afford the maximum resiliency of connection between the vehiclabodyand the base-bars,thus insuring the com fort of the occupant of the vehicle. The turning and backing of the vehicle are of course facilitated by the provision of the upwardly-curved ends at the rear of the runners, which are thus rendered capable of riding over obstructions in the road against which ordinary runners would abut. Said upwardly-curved rear ends are also of ad vantage in that they enable the runners to pass gradually down and up cradle-holes in the road without the jarring incident to the employment of ordinary runners which terminate abruptly.

I do not desire to limit myself to the precise details of construction and arrangement hereinbefore described, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.

I claim 1. In a sleigh-runner, the combination with a wooden base-bar having upwardly-curved ends; of a metal shoe fixed to said bar and projecting beyond the ends thereof; two trusses comprising downwardly-divergent limbs fixed to said base-bar; and means respectively connecting the projecting ends of said shoe with the respective crowns of said trusses, substantially as set forth.
