Definitions
- T 0 all whom it may concern Be it lmown that I, THOMAS S. SPEAK- MAN, of the city of Philadelphia, in the- State of Pennsylvania, have made a new and useful improvement in the manner of constructing drays, carts, and other vehicles of a like character, by means of which improvement the horse is greatly relieved from the injurious effect of the numerous and incessant jolts occasioned by the passing thereof over the paving-stones and other inequalities of the road; and I do hereby declare that the following is a full and exact description thereof.
- My improvement consists in the combining of elliptic, semi-elliptic, or other suitable springs with the back-chain which passes over the back of the horse, and sustains the pressure of the load. Under each shaft there is one of these springs, to which are attached iron staples that pass through suitable holes in the shafts, and the upper ends of which are attached likewise to the backchain.

UNITED STATES PATENT OFEIQ.
THOMAS S. SPEAKMAN, OF PHILADELPHIA, PENNSYLVANIA.
COMBINATION OF SPRINGS WITH THE BACK-CHAIN 0F CARTS, &c.
My improvement consists in the combining of elliptic, semi-elliptic, or other suitable springs with the back-chain which passes over the back of the horse, and sustains the pressure of the load. Under each shaft there is one of these springs, to which are attached iron staples that pass through suitable holes in the shafts, and the upper ends of which are attached likewise to the backchain.
In the accompanying drawing A, A, show upper and lower sides of the shaft, where the staples pass through, for the purpose of strengthening them, and to serve as bearings for the semi-elliptical or other springs.
Specification of Letters Patent No. 5,673, dated July 18, 1848.
above described device, which affords the same relief in these vehicles that is afforded by the ordinary elliptic springs, when placed under the body of a wagon, or other carrlage.
Having thus fully described the nature of my improvement in the manner of constructing drays, carts, and other vehicles of a like character, what I claim therein as new, and desire to secure by Letters Patent, 1s-
1. The combining with each end of the chain that passes over the back of the horse, of a semi-elliptical, or other suitable spring, which spring is to bear against the under side of each of the shafts, in the manner and for the purpose herein fully made known.
2. I do not claim as new the spring, or any other individual part of the apparatus herein described, but I do claim that combination and arrangement of such parts as set forth, by means of which a new and very useful effect is produced.
THOMAS S. SPEAKMAN.
