JOHN HIMELSBAGH AND GOTTLEB W'ENNINGER, OF LANCASTER, PA.
IMI ROVEMENT lN SHIFTING SEATS FOR VEHICLES.
Specification forming part of Letters Patent No. 221,654, dated November 11, 1879 application filed February 12, 1879.
To all whom it may concern:
Be it known that we, JOHN HIMELSBACH and GOTTLEB WENNINGER, of Lancaster city and county, State of Pennsylvania, have invented certain Improvements in Shifting or Jump Seats in Vehicles, of which the following is a specification.
This invention relates to a class of shifting or jump seats in vehicles in which the front seat can be lowered and folded back, and the hind seat thrown forward over it.
Thenovelty consists in constituting the lazybackordinarily in use into a lever to unlock a perforated bar from a fixed bolt or spur, and an oblique central brace on each side, besides other improvements herein set forth.
The accompanying drawings, with the letters of reference marked thereon, and a brief explanation will enable those skilled in the art to make and use the same.
In the drawings, Figure 1 is a side elevation to show both seats, the dotted lines indicating their position when the front seat is thrown back and lowered and the hind seat brought forward over it. Fig. 2 is a perspective diagram of certain parts hidden from view, to illustrate the construction and combination.
The upper plate; 1, under the seat A, to which the legs are hinged in the ears K, has a branch plate at right angles, (marked t',) to which a lateral or oblique brace or third leg, P, is hinged and carried down tothe sill-plate '0, to which it is hinged between the legs L.
The rear leg L-of the seat A has a side branch or bolt, T, near its upper end and on its inner face. This spur 0r bolt is rounded off on its upper end, the better to slide or look into a perforated lock-bar, G, which has an inclined groove on its under side (marked g) to ease 0E and allow the bolt to glidein the groove gradually to the perforation when raising or lowering the seat. This lock-bar Gr is hinged in front to a double bearing on the plate I to receive it, and is held by the same pivot that holds the front leg. This bar G extends back behind the leg, where it is hinged to arod, F. This rod connects with the end of the iron 0, that forms the lazy-back with the top a. This end referred to is marked E, and the fulcrum is at D. A strong fiat spring, S, attached under the seat, extends and bears upon the lockbar G aforesaid.
The operation is such that by drawing the lazy-back forward and down upon the seat it acts as a lever on its fulcrum D (connected with the side rail, B) by its connection with the bar or red F, which raises the end of the inclined lock-bar Gr up and out of the fixed bolt or spur T on the leg, and suffers the hinged legs to fold down either back or forward. The inclined grooved ways to and from the perforation or eye in the lock-bar ease off the abrupt mounting, and act as guides. The spring-action bearing upon the bar acts as in a sliding latch, to facilitate it in looking, so that a little power applied will raise the seat and bring it into position with case at any point of contact to raise it. We also curve the legs on the hind seat, in order to shorten the middle prop, M, on the upper plate, J. This prop M has the lower edge beveled out to fit over a bevel ridge made upon a projecting shoulder, 1 on edge of the legs L, facing each other, so that the end of the prop comes nearly in a direct line with the leg, 'both to distribute the pressure centrally from the weight on the seat as well as to prevent lateral motion to a great extent, making it simple, strong, and easily operated.
We are aware that intermediate props are used on hinged cross-bars from one leg to the other, as well as affixed both to the sill-plates and seat-plates, differing in construction, and bringing the strain rather across the middle of the leg as a fulcrum, so that a sudden plunge into a rut or hollow would tend to break the leg, which is not the case when the legs are but slightly curved, and by the enlarged portion receive the pressure in a line with their length toward the center of the generalbearing; hence we deem it an improvement differing substantially in its results from mere props upon which the legs fall to stay them in a line across the metal; therefore,
What we claim as our invention in jump seats islique prop or third leg P, its lower end piv' oted on the sill-plate 0 between the other legs and lowered and folded as and in the manner set forth.
