JACOB KNAPP, OF CINCINNATI, OHIO.-
SHlFTlNG-RAIL FOR VEHICLES.
SPECIFICATION forming part of Letters Patent NO. 294,788, dated March 11, 1884.
Application filed December 24, 1883. (No model.) i
which the following is a specification, reference being had therein to the accompanying drawings.
My invention comprises a special form of clip-nut that enables the back-braces, armrests, and rail of any kind of a vehicle to be readily coupled to the seat-irons and to be as readily detached from these irons when occa- Said device consists of a,
hub or nut proper, which is adapted to be traversed with the back-braces and front ends of the arm-rests, the nut having a hook-shaped clip that. engages over or under the rail, to which latter the buggy-top is applied in the usual manner. The clips being hooked over this rail and the proper ends of the back-braces and arm-rests being passed through the hubs, and also through suitable holes in the seatirons, ordinary nuts are then screwed onto said braces and rests, thereby clamping said rail, braces, and rests immovably to said irons, as hereinafter more fully described.
In the annexed drawings, Figure l is a perspective View of a buggy-seat provided with my improved attachments. Fig. 2 isan enlarged vertical section through one of my clipnuts and its accessories. Figs. 3 and 4 are similar sections of two modifications of the invention.
Referring to Fig. 2, Arepresents the hub of the nut, which hub may be of any ornamental shape, and is here represented as being screwthreaded internally at B, to admit the male threads cut on the proper ends of the backbraces and arm-rests. Projecting from this hub or 'nut is a hook-shaped Y clip, 0, adapted to engage snugly over an ordinary rail, D, which has the customary front bearings, E E, and back-props F F, for supporting the buggy-top in the usual manner. Secured to the vehicle-seat G are the irons H, pierced near their outer ends, as shown at I in Figs. 2, 3, and 4:.
J J are customary braces that assist in supporting the back K, the lower ends of said braces having threads jj out upon them.
L L are arm-rests attached at rear to the back K, and having their front ends threaded at Z Z.
N are customary nuts that engage with the screws j j Z l and bolts 0 O, the latter being fastened in the seat-irons located near the back props, F F.
' After the perforated irons H I have been properly fastened to the seat G, the rail D is placed in position on said irons, and the clipnuts A are engaged with the threaded ends jj and Z Z of the back-braces and arm-rests, care being taken to have the hooks G of said nuts presented toward said rail. These threaded ends of the braces and rests being now passed through the perforations I of irons H and the nuts N screwed upon said threaded endsjj U, the rail D is not only immovably clamped to said irons, but at the same time the back K is fastened to the seat G. Finally, the short bolts or screws 0 O are then engaged with the rear irons atthe opposite sides of the seat, for the purpose of stiffening the rail in the immediate neighborhood of the back-propsF F. This act completes the application of my attaohments and affords a structure that is practically as durable and secure as though the rail, backbraces, and arm-rests were welded to the seatirons, and yet the construction is such as to allow the ready removal of the buggy-top at any time. This removal is effected by simply disengaging the various nuts N and removing the back K, with its braces J J L L, so as to allow the railD and its attached top to be at once .lifted off the seat, to which latter said back can be again applied in a few minutes.
Reference to Fig. 2 shows that the hook or clip 0 is made sufficiently short to avoid coming in contact with the seat-iron H when the hub A B is screwed firmly against said iron. This arrangement secures the most rigid clampingof the railD in its proper place; but to prevent the possibility of a person s garments being caught under the end of said hook, the latter may be extended so as to enter a groove or pit, h, in the upper surface of the seat-iron, as seen in Fig. 3. Furthermore, this illustration shows that the hub Ahas a smooth bore, 1?, to to admit the unthreaded brace J, the latter inwardly-projecting hooks C, that grasp the rail 1), said nuts being traversed bythelower ends of back-braces J J and arm-rests L L, which braces and rests are retained in place by screwing upon them the customary nuts N, as herein described.
In testimony whereof I alfix my signature in I presence of two witnesses.
having a collar, R, swaged on it which collar rests upon said hub. In Fig. l the seat-iron H has an upward bend, S, to receive the top of rail D, the clip-nut A 0 being in this case applied beneath said rail, where it will not be so conspicuous. It will thus be seen that said nut can be applied in any manner that will be most effective in clamping the rail to the seat- 11011S.
I claim as my invention In combination with the ordinary seat-irons H, perforated at I, the nuts A, provided with \Vitnesses:
