GEORGE W. KEER, OF BRIDGEPORT, CONNECTICUT.
Two-WHEELED vement'.`
SPECIFICATION forming part of Letters Patent No. 293,474, dated February 12, 1884.
Application filed December 3, 1883. 4(No model.)
To a/ZZ whom t may concern.- 1
Be it known that I, GEORGE W. Kenn, a
` citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain newr and useful Improvements in Oscillating Shaft Attachments vfor TwoVheeled Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v
My invention relates to certain novel and useful improvements in the. construction of two-wheeled vehicles, and has for its object to relieve the body of the vehicle from the disagreeable motionfof the horse, while at the same time the shafts shall be attached to said body, which permits both endsof said body to rise and fall uniformly in passing over uneven roads or obstructions, `While at the same time all rattling from the side motion of the shafts is prevented; and with these endsin view my4 invention consists in the details of construction and combination of elements hereinafter fully and in detail explained, and then specifically designated by the claims.
In order that those skilled in the art to which my invention appertains may more fully nnderstand the same, I will proceed to describe its construction and operation, referring by letters to the accompanying drawings, forming a part of this specification, in which Figure l isa side elevation of a two-wheeled vehicle constructed in accordance with my improvement; Fig. 2, a bottom view with the body-springs removed; Fig. 3, a detail view of the spring and its attachments, showing the shaft and body in section; and Fig. 4, a detail view of the housing, within which the rear extremities of the shafts project.
Similar letters denote like parts in the several figures ofthe drawings.
A is the body of the vehicle, which rests on springs in the ordinary manner.
B are plates bolted to the bottom of the body, and having projecting therefrom or attached rigidly thereto pins C.
D are the shafts, having secured thereto lugs E, through whichthe pins C are loosely passed, so 'that said shafts will be pivoted at that point.
F are coil-springs wound around the pins C, and attached at their extremities, in any or dinary way, to the plates B andlugs E. These `springs have a threefold function. In theiirst place they take up the motion imparted to the shafts by the movements of the horse and prevent its transmission to the body of the vehicle; secondly, in passing over an obstruction, as the shafts and body have independent motion,'it follows necessarily that both ends of the body rise and fall equally; and, thirdly, these springs form perfect anti-rattlers, as they serve to take up the slight side motion of the shafts, which causes extremely disagreeable rattling in all vehicles of this class as now constructed. The rear ends of the shafts project within housings G, secured to the sides of the vehicle-body. The top andbottom of these housings are constructed of rubber blocks H, or any other material adapted to act as cushions, against which said shafts may abut, as will be presently explained, the normal acA tion of the springs E being to hol-d the shafts in the center of the housings, as clearlyshown in Figs. l and 4. a
As the vehicle is being drawn over the road, all the motion from the horse is communicated, of course, to the shafts. This causes the latter to vibrate with a spring movement at their pivotal point without imparting any motion whatever to the body ofthe vehicle. At any extraordinary vibration of the shafts, the rear extremities thereof' will strike against the cushions H, which not only checks the movement of the shafts and relieves the horse, but also prevents any'shock on the body.
My improvement is readily adapted to any two-wheel vehicle, it only being necessary to attach the shafts in the improved manner which I have shown.
I do not wish to confine myselfto the exact shape and style of housingV shown, as any yieldingabutment may be used, the gist of my IOO springs, as described, 'eoiledabout the.- pins with the spiral springs Which aet to vtake up the connecting the body to the shafts, in eo1nbi1aa- Vertical -andhorizontal motion of the shafts, tion with said body and the shafts, substanand the housings provided with cushions, 15 tially as and for the purpose hereinbefore set against which the ends of the shafts may abut,
