DANIEL ARNOLD SPRAGUE, OF POLAND, NEW YORK, ASSIGNOB OF ONE- HALF TO CHARLES A. SPRAGUE, OF SAME PLACE.

VEHICLE RUNNING-GEAR.

SPECIFICATION forming part of Reissued Letters Patent No. 10,800, dated January 18,1887. Original No. 348,642, dated September 7, 1886. Application for reissue filed November 15, 1886. Serial No. 218,959.

To all whom it may concern.-

Be it known that I, DANIEL ARNOLD SPRAGUE, of Poland, in the county of Herkimer and State of New York. have invented certain new and useful Improvements in Running-Gear for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap 1c pertains to make and use the same.

My invention relates to an improvement in running-gear for vehicles.

The object is to provide a neat, strong, convenient, and durable vehicle which may be constructed at a reduced cost.

\Vith these ends in view my invention consists in a running-gear in which the springs are attached directly to the reach or reaches at points quite near the axles, and either in front or back of the axle.

My invention further consists in certain featu res of construction and combinations of parts, as will be' hereinafter described, and pointed out. in the claims.

In the accompanying drawings, Figure l is a bottom plan view of gear, and Fig. 2 is a vertical longitudinal section through the center.

A represents the front axle, and A the rear axle. A reach, B, consisting of a single bar, or it may consist of two or more bars, is secured to the under side of the rear axle and to a short cross-head, Q, located over the front axle, and having the-upper section, D, of the fifth-wheel secured to its underside. The king- 5 bolt E passes through the cross-head O, reachbar B, and axle A, and the axle A may be provided with bearing-plates at the points a, where the fifth-wheel section D engages it; or it'may have a lower fifth-wheelsectionsecured thereto, 0 as is common. The rear axle is preferably straight and the front axle curved downwardly at the middle, in order that the approved difference in the diameters of the rear and front wheels may not be more than compensated for 4 5 by placing the reach below the rear axle and above the front axle, as shown. The ends of the reach bar or bars extend a short distance to the front of the front axle and tothe rear of the rear axle.

A pair of springs, D, either elliptical, as

the load nearer the point of support.

shown, or semielliptical, or of any other approved form, are secured to the under side of the reach bar or bars at points quite near the axles,and either in front of or behind said axles. The reach bar or bars are straight, or nearly so, and by securing the springs to the under side of the reach the center of gravity of the body G is brought as low as possible with respect to the points of support, and at the same time admit of a free compression and expansion of the springs. The rolling motion of the body is thus avoided to a great extent, while the straight reach employed may be provided at a less cost than bent reaches, and serves to more directly connect and steady the axles.

The springs F might be attached to the reach close to the rear of the front axle and front of the rear axle, orthey might be attached either both in front of their respective axles or both in the rear of their axles, the gist of my invention being the attachment of the springs in close proximity to the axles, either in front or rear of the same, and the attachment of the springs to the under side of a straight reach bar or bars, to bring the center of gravity of This construction is particularly.applicable to the buck-board style of wagon, as it prevents almost entirely the continuous humming sound or muffled rattle which has hitherto proved so annoying.

I am aware that it is not broadly newto attach springs directly to the reach; but hereto fore the reach has commonly been bent to lower the springs, and the springs have been attached quite a distance from the axles to escape the bent in the reach, and have been in the way of cramping the wheel, and have not been so located as to hold the body steady.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In running-gear for vehicles, the combination, with one or more reach-bars secured below the rear axle and above the front axle, 5 of bodysupporting springs secured to the reach bar or bars in front of the front axle and in the rear of the rear axle, respectively, substantially asset forth.

2. In running-gear for vehicles, the combi- I00 nation, with one or more straight reach-bars, bars, of a body-supporting spring secured at a 15 of a pair of body-supporting springs secured point between its'ends to the under side of the to the under side of the reach bar or bars, one reach bar or bars near to the frontor rear axle. in front of the front axle and the other to the 5. In running-gear for vehieles, the combi- 5 rear of the rear axle, substantially asset forth. 1 nation, with one or more straight reach bar or 3. In running-gear for vehicles, the straight bars, of body-supporting springs located near 20 reaehbar projecting to the front and rear of the front and rear axles, each spring being sethe front and rear axles, the cross-head and cured at a point between its ends to the under fifth-Wheel section attached thereto, and the sideof the reach bar or bars. 7 1o springs secured to the under sides of the pro- T jecting ends of the reach, the Whole constructed DANIEL ARA OLD VSPRAGUE' and arranged substantially as set forth. \Vitnesses:
