SULKY.

SPECIFICATION forming part of Letters Patent No.521,460, dated June 19, 1894.

Application filed December 16 1892. Serial No. 455,329. (No model.)

To all whom it may concern.-

Be it known that I, STERLING ELLIOTT, of

Newton, county of Middlesex, State of Massachusetts, have invented an Improvement in Sulkies, of which the following description, in connection with the accompanying drawings, isa specification, like letters and figures on the drawings representing like parts.

In sulkies as now commonly made the shafts have been composed each of a single long slender bar, and as the front ends thereof are repeatedly and quickly raised by the horse in trotting, the said shafts spring or vibrate,

thereby unduly vibrating the load, and having a tendency to disturb the even gait of the horse, and also to disturb the driver. It has also been the aim to place the seat directly above the axle so that the weight of the rider will be balanced as nearly as possible, and as the sulky is vibrated the rider'is moved from one to the other side of a point in a vertical plane with the axle. The seat, so arranged, therefore enhances the tendency of the shafts to spring and increases the vibration of the sulky, because when the preponderance of the weight of the rider is thrown to the rear of the axle, gravity cannot restore it to its normal position. The stirrups or foot rests have been arranged on the inside of the horizontal shafts, whilethe seat has been supported in' a plane but little above the shafts so that the legs of the driver have been brought into nearly horizontal position, and when driving he usually bends forward, thereby assuming a most unnatural position, which it has been found in'practice is conducive to many permanent physical injuries.

This invention has for its object to so improve the construction of sulkies that these serious objections may be overcome, and at the same time reduce its weight.

In carrying out this invention the shafts the divided portion of the shaft occupies substantially a horizontal plane, and is connected at the rear to the top of the wheel supporting cross-bar or frame, while the lower part or bar is connected to said frame at a point near the ground. To give as wide a divergence as possible to said divided portions of the shafts, and furnish-a suitable support to which the rear ends of the lower parts may be connected as well as for many other reasons, the wheels are made quite small in diameter, and turn on short axles supported at the lower ends onarms or forks which depend from the axle or frame.

The seat is located at such a point as to bring the preponderance of the weightof the rider continuously in front of the axle, so that as the sulky vibrates on the axles as pivots, his weight is moved from a point in advance of a vertical plane with said axles to a point substantially in said vertical plane, 7c

thereby depending upon' gravity to restore the weight.

The stirrups or foot rests are arranged below the horizontal portions of the shafts, so

natural position.

Many details of construction in the form of braces are provided which will be hereinafter described.

that the legs of the rider may assume a more 7 5 Figure 1, shows in side elevation a sulky 8o embodying this invention; Fig. 2, a rear side view of the sulky shown in Fig. 1, and Fig. 3, a plan view of the sulky shown in Fig. 1.

The cross-bar or frame a, which is or may be curved in any usual way, is provided at or position, as well as that class of sulkies in 5 which the usual form of shafts is employed, together with braces extending from beneath the shafts at a suitable point forwardly of the wheels, and thence backwardly to the wheel supports, the shafts of the present intoo vention difier in the respect of their being divided at points at or near to the forward ends thereof, say for instance, at the point2, about where the back strap is attached. The shafts are made alike and are constructed or formed preferably from a single piece of wood or other suitable material, possessing practically the same uniform thickness throughout, but the divisions of the shafts are made so that after the shafts are divided into the upper and lower portions 1), and b, a forwardly projecting end will remain undivided, substantially as appears in the drawlugs.

The two divided portions of the shafts occupy substantially the same vertical planes, the lower divided portion 1) being practically directly beneath the upper divided portion (1, the said upper portions 1), extending rearwardly and being curved as desired, and attached to the cross-bar or frame a at 3, and the lower portions Z2 also extending rear- Wardly and having their rearward extremities attached to the lower ends of the depending wheel supporting arms a. The lower divided portion 1) of each arm is split at a suitable distance from its rearward end to form two side arms b 11 which constitute practically a fork receiving the wheel, thereby securing a simple and effective formof attachment as well as a guard for each of the wheels. Instead of dividingthe rearward extremities of the lower portions 1), the said portions 12' may be made continuous, and attached at their lower extremities to the lower end of either the inside or outside depending arms, but I prefer to provide such arms 6 as I thereby obtain an extra stiffness to the frame, as Well as a strong and permanent guard for the wheels. In the event of dispensing with the said arms 11 and forming the lower divided portion Z) of a continuous piece, a divided shaft within the spirit and scope of this invention is provided.

The shafts are preferably constructed from a single piece,but it is apparent that the same could also be made of separate pieces bolted or otherwise secured together.

Struts or supports a, c are interposed between the upper and lower portions of the divided shafts, connecting them together, and braces c are provided, one end of which is connected to the upper divided portion of the shafts, and their opposite ends being connected to the extremities of the cross-bar or frame,thereby giving to the shafts additional stiffness and rigidity, like a truss.

The arms b 11 which constitute the forked guard, as hereinbefore explained, are preferably connected together by short cross-pieces or bars b, which are brought in front of the wheels, and suitable curved bars 0 are connected at their upper ends to the ends of the cross-bar or frame, while the lower ends thereof are connected to said short connecting bars b From the construction thus far explained, it will be seen that the rearward extremities of the upper portionsof the shafts extend backwardly and are suitably secured to the crossbar or frame, while the rearward extremities of thelower divided portions extend back and are attached or secured to the lower ends of one or the other of the depending wheel-supporting arms, thereby obtaining a construction differing essentially from this class of sulkies as heretofore constructed.

Instead of attaching the rearward extremities of the lower divided portions of the shafts to the lower ends of the depending arms, 1 may in some instances, construct such rearwardly extending extremities so as to receive the short axles or spindles upon which the wheels are directly supported, but preferably I resort to the arrangement herein shown.

The stirrups or foot rests are formed on the struts 0, being herein represented as formed by curving said struts outwardly, and pro viding additional struts c curved in the opposite direction, and connected at the ends to the upper and lower divided portions, and interposing cross-bar c between and connecting said struts 0, 0

This construction enables the stirrups or foot rests to be arranged below the horizontal portions of the shafts so that the legs of the rider may assume a more natural position.

A curved connecting rod or bar (Z is interposed between and connects the horizontal portions 12 of the shafts as usual, while the rear ends of said portions bare connected by the connecting bar (1', curved in the opposite direction, crossing and resting upon the axle or frame and connected thereto by bolts or otherwise, and also connected to the connecting bar d. By making this connecting bar d in the form shown additional supports are provided, and therefore additional stiffness given to the connected parts.

The seat 6 is supported by suitable props e in the usual way, but as best shown in Fig. 1, is located so that the preponderance of the weight of the rider is always in front of the point in a vertical plane passing through the axles of the wheels.

The Whittle-tree is pivoted in a suitable support rising from the connected bars (Z, d.

I do not desire to limit myself to the particular shape or construction of parts, as it is obvious that the shafts may be divided in different ways and provided with intermediate struts, and also that the stirrups or foot rests may be arranged below the shafts in different ways.

By providing the small wheels as shown good and sufficient connecting points are pro vided for the arms b h of the lower divided portion of the shafts, to thereby permit the introduction of struts or supports of suitable length to give great stiffness to the shafts, and furthermore the pivotal points on which the sulky vibrates are brought nearer the ground.

The shafts constructed in this way or in TOC any equivalent way cannot spring, yet in practice I find that the sulky can be made even lighter than when constructed in the usual way.

I claim 1. A sulky, each shaft of which is in a plane above the top of the wheels, bar at the forward end, and is split or divided back of said end, one portion extending horizontally to the seat and support, and the other extending at an angle to the first and downward to the axle, substantially as set forth.
