ROAD-CART.

SPECIFICATION forming part of Letters Patent No. 401,834, dated April 23,1889.

Application filed October 31, 1888 Serial No. 289,619. (No model.)

To all wiz-0111, it may concern.-

Be it known that I, JOHN GfA HESS, a citizen of the United States, residing at lVestminster, in the county of Carroll and State of Maryland, have invented new and useful Improvements in Road-Carts, of which the following is a specification.

This invention relates to improvements in road-carts, in which compactness and strength are the main desiderata; and it consists in a certain novel construction and combination of devices, fully described hereinafter in connection with the accompanying drawings, and specifically pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a vehicle embodying my improvements. Fig. 2 is a longitudinal sectional View of the same. Fig. 3 is a transverse sectional view taken in rear of the cross-bar. Fig. et is a detail sectional view on the line fr a; of Fig. 3. Fig. 5 is a detail view to show the connection of the spring to the axle. Fig. 6 is a detail view to show the connection of the thill to the axle.

Referring by letter to the drawings, A designates the cranked axles, having the outward offset, a, and the shoulders o a at the opposite ends of the offset, and B B designate the thills, which are attached at their rear ends to the axle outside of the said shoulders. Draft-straps b are secured to the rear ends of the thills and pass under the axle. Inclined brace-straps b are attached at their front ends to the thills and bear at their rear ends on the upper side of the axle, and small vertical bolts b2 b2 pass through the said straps on opposite sides of the axle to connect them firmly thereto.

C represents an upwardly-convexed semielliptical spring, which is arranged in the offset of the axle, and is provided at its ends with the loose swinging loops D D, which are engaged over the axle and bear against the shoulders ce a', whereby as the center of the spring is depressed and the extremities thereof are forced laterally the said loops swing on the axle and accommodate the said movement.

D represents the body of the cart, arranged between the thills and having the seat d and the splash-board d', and E E are rearwardlyextending arms on the bottom of the body, connected at their rear ends by the cross-brace F, that bears on the spring C, and is iirmly secured thereto at its center.

The cross-bar G between the thills passes in rear of the splash-board above the bottom of the body and over a transverse spring-bar, H, which is secured at its ends to the body and is supported at its center above the bottom of the body, and l represents a Whittletree which is swiveled on the upper side of the said cross-bar. The adjacent sides of the cross-bar and whifletree are provided, respectively, with wear-plates K and L, and the plate K is provided with a central opening, 7a, which iits around the lower end of a sleeve, Z,

which depends from the centerA of the plate L. The plate L is further provided near its outer edge with a peripheral downwardly-tapered depending iiange, Z', which fits snugly in the vertical upwardly-tapered flange 7c', which is formed on the upper side of the plate K.

A tubular or perforated block, M, is interposed between the under side of the cross-bar and the spring-bar H, and a vertical. bolt, N, passes through registering openings in the whiffletree, cross -bar, and spring-bar, and through the sleeve I of the wear-plate L and the tubular block, and is engaged at its lower end by a suitable nut, n. To take up lost motion between the whiftletree and the crossbar, tighten the vertical bolt, thereby drawing tapered ilange Z downward into the tapered flange 7c. cured at their ends to the rear side of the cross -bar and pass over the whifletree to limit the movement of the latter and prevent it from striking the splash-board.

From the above description it will be seen that the spring and cross-brace which connect.

the body to the axle are located in the offset of the said axle, thereby rendering this portion of the construction more compact, and, the cross-bar and whiffletree being arranged within the vehicle or in rear of the splashboard, the horse may be arranged closer to the vehicle, while at the same time the occupant of the vehicle is allowed plenty of room.

The slight vertical spring movement of the front end of the vehicle, owing to the transverse spring-bar which connects it to the crossn Flexible straps O O are se4 IOO bar, prevents undue jarring of the body of the vehicle, and allows, in connection with the spring at the rear end of the body, a gentle resiliency of movement.

Having thus described the invention, I claiml. In a road-cart, the combination of the axle, the thills connected thereto, the body connected at its rear end to the axle, andthe cross-bar G between the thills, passing over the floor of the body in rear of the splashboard, and connected to the body, substantially as specified.

2. In a road-cart, the combination of the axle having the thills attached thereto, the body connected to the axle and havinga transverse spring-bar, H, in rear of the splashboard, the cross-bar G, connecting the thills and passing over the said springbar, the Wear-plateon the upper side of the cross-bar provided with a vertical tapered flange, 7c', the whifiietree arranged on the upper side of the cross-bar and providedon its under side with a depending tapered flange, Z, fitting within the flange c, and the bolt passing through registering perforations in the whiffletree, cross-bar, and spring-bar, substantially as and for the purpose specified.

3. In aroad-cart, the com bination,with the axle, of the thills and draftstraps b and inclinedA brace-straps b, secured to the rear ends of the thills and arranged at. their rear ends respectively below and above the axle, and the bolts connecting the rear ends of the, said straps on opposite sides of the axle, saidbolts bearing against the axle, substantially as specified.

4. In a road-cart, the combination, with a cranked axle provided with the upward offset a and the thills connected to the straight portion of the axle on opposite sides of the offset, of the semi-elliptical, spring arranged Within and below the offset and connected at its ends to the shoulders a of the offset, and the body having its main portion arranged forward of the axle and its seat directly above the same, and provided with a cross-brace, F, arranged parallel with and bearing on the said spring, and the horizontal arms E, connecting the cross-brace with the rear` portion of the body, substantially as specified.

5.v 1n a road-cart, the combination, with a cranked axle provided with the offset a and the shoulders a a on opposite sides of the offset, and the thills attached at their rear ends to the straight portion of the axle beyond the shoulders, of the spring C, arranged Vwithin and below the said offset and provided at its ends with swinging loops D D,

passing over the axle and engaging the shoulders a a', the body provided with rearwardly-extending armss E E, the cross-brace F, connecting the rear ends of the said arms and secured tothe center of the said spring, and the cross-bar G between the thills, connected to the front of the body, substantially as specified.

6. In a road-cart, the combination, with the cranked axle and the thills affixed to the axle, of the spring C, provided at its ends with swinging loops D D, passing over the axle, and the body provided at its rear end with a cross-bace, F, arranged parallel with and bearing on and affixed to the said spring, said cross-brace and said spring being arranged within andl below thecranked portion of the axle, and said body being connected'at its front end to the cross-bar G of the thills by a yielding or spring connection, substantially as specied.
