SPECIFICATION forming part of Iletters Patent No. 376,887, dated Januaz-y 24., 1888. Application filed October 24, 1887. Serial No. 233,241. (ModelJ To all whom it may concern:
Be it knownithat I, SAMUEL B. IRWIN, of
tain new and useful Improvements in Vehicle-Seats; 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 pertains to make and use it, reference being bad to the accompanying drawing, which forms part of this specification. I g
My invention relates to an improvementin vehicle-seats; and it consists in the combination of the pivoted back, the arms connected thereto, and a crankedrod, to which the front ends of the arms are connected,as will be more fully described hereinafter.
The object of my invention is to provide a back for vehicle-seats which can be adjusted so as to stand vertically or be inclined backward, as may be desired, to balance the vehicle.
The accompanying drawing represents a perspective of a seat to which myinventio-n is.
seat, and to'which ears B are pivoted thesupporting-rods O of the back D. These rods 0 are pivoted at their lower ends to the seat A, for the purpose of allowing the back to be adsition, as may be preferred. Pivoted to opposite ends of this back D are the arms or rods E, which have their front ends piv is journaled upon the front edge of the seat A in suitable boxes, G. This rod F has a turning movement, so as to move its cranked ends through little over ahalf of a circle, as shown in dotted lines, and thus either draw the "arms E and back D forward or force them backward, as may be desired. When the cranked ends are thrown downward, the back D is drawn forward so as to assume avertical position; but when the cranked ends are moved backward the back D and arms E are forced correspondingly backward, and the backl) assumes an inclined position,.as shown. By means of this construction the back D can be raised into a vertical position,so as to support the back, or it can be moved into an inclined position, either to allow the driver to incline backward or to have it moved out ofcontact in which case it is necessary to operate them both at thesame time.
This invention is especially intended forroad-carts or two-wheeled vehicles, in which the vertical movement of the shaft, as in going up or down hill, changes the balance of the riders. In going downhill a stationary back compels the riders to lean forward, thus causj 7 ing their whole weight to be thrown upon the shafts, and in going uphill, ifthe ride'rslean against the back, the center of gravity is thrown behind the axle, causing theshafts to rise in the shaft-tugs, and thus impede the movement of the horse. 'By having the seat mov- As here shown, the twoable the riders can adjust themselves by means The combination of the seat,the baek'loosely 'connectedthereto, the arms connected to the back, and the cranks for adjusting the back,
