SPECIFICATION forming part of Letters Patent No. 327,019, dated September 29,1885;

Application filed August13, 181 4. (No model.)

To aZZ whom it may concern.-

Be it known that we, FREDRIOK A. REH- KoPFand CHARLES A. ROGERS, residing at Chicago, county of Cook, and State of Illinois,

5 have invented certain new and useful Improvements in Road-Carts; and we do hereby declare the following to be a full, clear, and exact description of said improvements, sufficient to enable others skilled in the art to which they appertain to make and use the same.

In two-wheel road-carts of the old construc tion the occupants are subjected to an annoying jerky sensation, due to the movements of I the horse and to the rigid connection between the thills and wagon-body. Our invention is designed more especially to obviate this defect; and it consists, primarily, in joining the thills, not, as heretofore, di-

rectly to the wagon-body, but to one end of a torsion-spring bar, the opposite end whereof is secured to the hound-bar or other convenient fixed portion of the cart. Said springbar serves not merely as a connection, but, by

reason of its elasticity, acts also to take up and neutralize thejolting motion which would otherwise be communicated from the horse to the cart.

The invention further consists in aguard or shaft extension to act in conjunction with the yielding thill-coupling, and by contact with a stationary part of the wagon-body to control the movement of the shaft.

In the accompanyingdrawings, which form 3 5 part of this specification, like letters of reference denote like parts throughout.

Figurel is a view in side elevation, and Fig. 2 a bottom plan View, of a roadcart embodying our improvement.

Rigidly attached to the wagonbody A is the cross-bar a, the extended ends of which, as at a are secured to theside springs, B, and permit of an easy cradle-like movement of the wagon-body within and upon said springs. 5 Springs B are fastened by usual clip, 810., to

the axle 1), upon which are mounted the wheels I), as well understood. At the front of Wagonbody A is secured the houndbar G, and at each side of said hound, so as to extend slightly 5o beyond the outer ends thereof, is a torsionspring draft-bar, c. The spring draft-bar 0 may be formed of tempered steel, and preferably has welded thereto at its ends the flat plates, as at c, by which the spring draft-bar may be bolted to the hound and to the thillD, respectively. The usual brace, d, may besecured at its end by the same bolt which holds plate 0 to the shaft. A journal-plate, 0, fastened to the bound, incloses the spring draftbar and serves to sustain the same near the outer end, relieving the main fastenings ofsald spring draftbar from undue strain, and holding the shafts to their work, without,however, affecting the easy rotary or torsional movement of the spring draft-bar.

From this organization of parts it will be understood that the jolting action of shafts D, when the horse is in motion, instead-of being communicated directly to the hound O, and so to the wagon-body, will be taken up and neutralized by torsional strain on the intermediate spring bar, 0, and much greater comfort be thereby insured to the occupants of the cart. VVhilethe torsionspring bar is shown and described as secured to the houndbar, it is manifest that as the latter exercises no peculiar function as such, but furnishes merely a convenient means for attachment, it might readily be dispensed with and the torsion-bar bejoined directly to the wagon- 8o bodv.

Extending backward from the shafts D, to which'jthey are fastened, are the guards E, having forked ends, as at e, to strike the abutting ends of crossbar a, or other convenient stay-piece projecting at the sides from the wagon-body. Rubber cushions e are slipped over the forks e, and are retained by the tie c and by the setnuts a on forkslfe acting in conj unction therewith. The tie 6 also serves to 9 strengthen the forks against the strains to which they may be subjected.

As thus constructed, the guard or shaft extension E 00 operates with torsion-harp to neutralize the jerking action of the shaft. In either the upward or downward movement of the shaft aboutthe spring' thill-coupling the forks e of the guard, when they encounter the stay-piece a, tend to throw the further leverage of the shaft ultimately upon the side spring,B, I

of the vehicle; but before this occurs the thills were not secured to the wagon-body at springbufi'ers e, by striking upon the stay a, will ordinarily suffice of themselves to take up the shalt movement and to neutralize the jolt. Other forms of buffer 6' may be employed without departing from the invention,which involves the employment of the guard to supplement the action of the torsionspring thillcoupling.

The foot-step F is secured, by Welding or otherwise, directly to the guard E, and when sustaining the weight of a person causes the up'-' per fork, e, of said guard to bear upon the stay a, and so to furnish a firm support.

The equalizing-bar G. mounted in journalplates, as at g, beneath the cart-body, has its crank ends g1 joined pivotally, as at y, to the side springs, B. In mounting into or dismounting from the cart at either side, the body of the cart is more or less depressed and gives a disagreeable lurch. To remedy this objection is the purpose of the equalizing-bar, for when the cart and its springs are depressed at either side the crank-arm 9, attached to such spring, is forced downward,and in consequence tends to force down the opposite crankarm and side spring, B; hence the descent is approximately equalized, since the weight is evenly distributedupon both side springs,

We are'aware that prior to our invention the thills of road-carts had been pivotally coupled to the wagon-body by a stout journal bolt or pin, about which a coil-spring was set, the ends of said spring being secured to the body and thill, respectively, to insure requisite elasticity in the connection. In our .device the coil-spring is dispensed with, and a torsionbar employed in lieu of the journalbo1t,which bar, being suitably tempered. acts not only to connect the thill and wagon-body, \but furnishes in itself the elastic tension previously derived from the separate coil-spring. We are aware also that torsion-spring rods have -heretofore been arranged between the t-hills and'the wagon-body of road-carts; but such springs were light and delicate, They did not serve to connect or sustain the thill about the wagon-body, and in consequence did n'ottake the direct strain of the draft. The
