ROAD-CART.

SPECIFICATION forming part of Letters Iatent No. 410,353, dated September 3, 1889.

Application filed December 28, 1888. Serial No. 294,345- (No model.)

To all whom it may concern:

. Be it known that I, EMMET VARREN DOO- LITTLE, of Garden Grove, in the county of Decatur and State of Iowa, have invented a new and Improved Road-(Dart, of which the following is a full, clear, 31 16. exact description.

The invention relates to two-wheeled vehicles; and its object is to provide a new and improved road-cart which is simple and durable in construction and greatly lessens the disagreeable jogging motion imparted to the vehicle by the step of the horse.

The invention consists in certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is a sectional side elevation of the same on the line a: 00 of Fig. 1. Fig. 3 is asectional side elevation of a modified form of the same, and Fig. 4 is a transverse section of the seat part of the same on the line '1/ g of Fig. 8.

The improved road-cart A is provided with the two wheels B B, mounted to turn 011 the axle O, on which are secured the upwardly and forwardly extending short shafts D, united near their front ends by the transverse beam D. On the front ends of the short shafts D are secured the lugs E, on which are pivoted thelong shafts F, to which the horse is hitched, and extending at the rear end beyond the pivot-point under the shafts D. The rear end of each long shaft F is provided with a slot F, in which fits one end of a spring G, pref erably coiled in the shape shown in Figs. 1 and 2. The other end of each spring G is secured to the corresponding shaft D between the axle O and the transverse beam D, as is plainly shown in Figs. 1 and 2. In front of the lugs E of the shafts F is secured the usual transverse beam F on which is pivoted the whiffletree to which the traces of the horse are attached To the transverse beam D are secured the ends of the springs H, which are similar in construction to the springs G, and are connected at their other ends with the bent bars I, supporting the platform or footrest- J. The bars I at the rear of the platform J are bent upward and then rearward, and carry at their outer upper ends a transverse beam I, on which rests the seat K. The latter is provided with longitudinal slots K, through which pass the bolts L, also passing through the transverse beam 1. On the lower threaded endsof the bolts L screw the winged nuts L, against the under side of the transverse beam I, so as to hold the seat K in place on the said bars I. Theslots K permit the longitudinal adjustment of the seat K according to the weight to be sustained on the seat. On the under side of the transverse beam 1 is secured a spring N, which may be of the usual elliptical form, as illustrated in Figs. 1 and 2, or of 'the shape illustrated in Figs. 3 and 4, in which part of the spring is coiled. The spring N is secured in its middle to the middle part of the beam 1, and extends equal distances on each side, being pivotally connected at its outer ends with the free ends of the springs O, secured at their other ends to the tops of the short shafts D. The springs 0 may be of the shape shown in Fig. 2, or as illustrated in Fig. 3. The springs 0 may be adjusted on the short shafts D for a heavy or light load by providing the shafts with slots, through which pass the bolts securing the springs O to the shafts, as shown in Fig. 2.

The operation is as follows: When the several parts are in place, as illustrated in the drawings, and the horse is hitched to the long shafts and draws the vehicle forward, then the jogging motion of the horse is not transmitted to the seat and the person seated 011 the same, on account of the shafts F being pivoted to the short shafts D and the springs G being interposed between the said shafts. Further, the jogging motion is not felt by the person on the seat 011 account of the latter being supported on springs from the short shafts D, as previously described. It is understood that the swinging motion of the long shafts F on their pivots on the lugs E is taken up by the springs G, connected with the slotted ends of the shafts F. 7

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

1-. In a road-cart, the combination, with the short shafts secured at their lower rear ends to the axle and curved upward and forward therefrom, of the long shafts pivoted near their rear ends to the forward upper ends of the short shafts, and a spring connecting the rear ends of said long shafts with the under sides of the short shafts, substantially as set forth.

2. In aroad'cart, the combination, with the short shafts curved downward at their rear ends and secured to the shaft, a cross-piece uniting the said shafts, of the long shafts pivoted near their rear ends to the forward upward ends of the short shafts, transverse coiled springs G connecting the rear ends of the long shafts with the under sides of the short shafts at their bends, substantially as set forth. v

3. The combination, with the short shafts curved upward and forward from the axle, a cross-piece connecting their front ends, and the springs H, secured to the said cross-piece, of the foot-rest and seat-supporting bars I, supported at their forward lower ends by the said springs H, the upper ends of the bars being projected rearward beyond the axle, and supporting-springs for said upper ends projecting rearward from the short shafts, substantially as set forth.

4. In a road-cart, the combination,with short shafts secured to the axle and long shafts pivotally connected with the said short shafts, of rearwardly-extending springs secured to the said short shafts, a transverse spring connected with the ends of the said shaft-springs, a seat supported 011 the said transverse spring, bars connected with the said seat and supporting the platform, and springs connected with the said bars at their front ends and secured to the front ends of the said short shafts,,substantially as shown and described.

5. In aroad-cart, the co1nbinati0n,With short shafts secured to the axle and long shafts pivotally connected with the said short shafts, of

rearwardly-extending springs secured to the said short shafts, a transverse spring connected with the ends of the said shaftsprings,

a seat supported on the said transverse spring,

bars connected with the said seat and supporting the platform, springs connected with the said bars at their front ends and secured to the front ends of the said short shafts, and bolts passing through longitudinal slots in the said seat for adjusting the said seat, substantially as shown and described.
