CAR-DOOR.
SPECIFICATION forming part of Letters Patent No. 389,706, dated September 18, 1888.
7 Application filed April 10, 1888. Serial No. 270,236. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM J. KEYEs, of Wheeling, in the county of Jefferson and State of Alabama, have invented a new and useful,
Improvementin Car and other Doors, of which the following is a specification.
This invention has relation to certain improvements indoors especially adapted for freight-cars, while it is also applicable wherever a closure of this character is availableas, for instance, in dwellings, or in connection with blinds, gates, or barn-doors, and has for its object to efi'ect security and readiness in opening and closing the door.
To these ends the invention consists of means for effectively securing the door, as also in readily opening and automatically closing the door, substantially as hereinafter more fully set forth, and pointed out in the claims.
In the accompanying drawing, Figure 1 is a perspective View of my improved car or other door, View from the outside. Fig. 2 is a side elevation of the same, taken from the inside. Fig. 3 is ahorizontal section. Figs. at and 5 are sectional elevations taken on the lines 00 x and y y of Fig. 2, respectively. Fig. 6is'an enlarged sectional view taken on the line zz of Fig. 2. Fig. 7 is a perspective view of the key used in connection with thedoorfastening. Fig. 8 is'an enlarged detailed perspective view of the catch, and Fig. 9 is a View showing a modification of my invention.
In carrying out my invention, I employ a toggle-lever mechanism or contrivance, comprising, principally, two levers, A A, and a link, A pivoted at one end to the lever A near its lower end, while the other end of said link is pivoted to the lever A at a point a little below the middle thereof, each end of the link being let into and held in passages or openings in the levers in anysuitable manner. The longer lever, A, is pivoted in the sill or threshold at, and normally extends obliquely crosswise of the door B, upon its inside, and upward to a point a little above the upper forward corner edge of the door. At this end it is beveled upon each'of two sides, as at M2, the bevel b inclining or sloping rearward, while the bevel b slopes in the opposite direction, or forward, the purpose of which will appear further on.
The shorter lever,A, has one end pivoted to said slot and entering or projecting from the jamb. The projection a is snugly received as the door is moved rearward into a recess or socket, a provided therefor by a notch in the lower end of the door-jamb c. The door B, while shown in the present instance as being reduced and bodily extended at its upper end or edge into a groove, 0, at the top edge of the door-opening and sliding or resting at its bottom edge immediately in contact with the sill or threshold a, yet it may be mounted or hung upon rollers, asis usual in sliding'doors.
Through. a passage or aperture in the extreme upper end of the lever A is passed a rope, f, or similar medium, which is knotted as at f f", one knot resting against the lever when the latter has reached the maximum limit of its forward movement, while the other knot limits the forward pull upon the rope. This rope is carried over a pulley, directly above the rear jamb, 0, that end thereof having attached to it a weight, It, depending or sliding in a suitable inclosure or boxing formed, .it may be, by the rear edge of the jamb c, and additional pieces secured to the inner side of the car-body. The ropefis also carried over a second pulley, i, hung in a strip orstudding, i. It may be secured upon the one side of the forward jamb, c, and extending edgewise through the car-body. It is thence extended down, outside of the car, and provided-with a knob, f'*, for its convenient manipulation.
O is a catch, which is provided at one end with a notch, into which is snapped or sprung and held the upper beveled end of the lever A when the door is locked or secured. The catch 0 consists of a short plug-like cylinder disposed in an aperture or socket extending transversely through tlie forward ja1nb,c,and the car-body, a little forward of and above the upper front corner edge of the door-opening, enabling the catch to stand in the path of the movement of the lever A. This catch has coiled around it a spring, j, which has its ends connected to the catch and the wall of its'aperture or socket, respectively, and which is adapted as the catch is turned so as to release its notched end from the leverA when the door is opened to coil or contract, and thus permit a recoil movement of the catch, whereby its notched end will again be brought into position to receive the beveled end of the lever A when the door is closed. The opposite end of the catch is disposed in alignment with and at the inner edge of the key-hole k, made in a cleat, 7e,fasteued to the outside of the ear-body, thus removing this end of the catch or bolt inwardly from a plane touching the outside of the ear. The said end of the catch or bolt 0 is formed with depressions k and intermediate projections or studs, k with which is adapted to engage the bits and intervening depressions of the key D,to effect the turning of the catch and consequently the unlocking of the door.
E is a blind or slide fitted to have movement in a chamber, 0, upon the inner side of the eleat k and to conceal from view the catch (I, standing normally in alignment with the latter. This blind or slide is connected at its upper end to a spring, Z, iuclosed within a casing or cylinder,Z,disposed in a chamber,whieh is formed by jointly reccssing opposite surfaces of the outside of the car-body and the cleat k. This casing or cylinder Z is connected or fastened in any suitable manner to the cleat 7c. The connection between the slide or blind E and the springlis effected, preferably,by means of a bail, 1*, with its ends connected to opposite corners of the upper end of the slide or blind, while its middle is connected to the lower end of a wire connected to the upper end of the spring and extending down within and below the lower end of the spring.
F is a bent or angular metal plate disposed within a recess or channel, on, in the clcat k, within which it is suitably guided by a crossplate, m, secured in the cleat crosswise of said recess or channel, as shown. The upper end of the plate F is connected by a wire or rod, a, to the slide or blind E, connecting with the lower end of said slide or blind, while the lower end of the plate projects laterally outward from and below the lower edge of the clcat is, to permit of its actuation by the thumb or otherwise.
In operation it will be seen that by pressing downward upon plate F to the required extent the slide or blind E is withdrawn or moved so as to expose the outer end of the catch or bolt O. The key D is now introduced so as to have engagement with the catch or bolt, and by turning it in the required direction-z'. 6., so as to bring the side thereof designated by a character representing, for instance, an ap proximation of the letter Vthe catch or bolt 0 will be disengaged from the lever A, effecting the release of the latter. The weighted ropef will now pull upon the lever A, which in turn will act through the link A upon and cause the lever A to pull or move the door rearward, thus effecting the automatic opening of the door. In order to effect a reverse movement of the aforesaid parts, as is required to close the door, it is only necessary to pull. upon the rope f by grasping and exerting downward pressure upon the knot f of said rope until the door is closed. In the meantime, or just as the door closes, the upper beveled end of the lever A will ride over the notched end of the belt or catch Oand drop in front of and be caught by the said end of the catch or bolt,effectually securing the lever and thus locking the door. After the required turning of the catch or bolt 0 and the removal of the key D from its hole, and the thumb or other pressure from the plate F, the slide or blind E will automatically return to its former position, concealing from view the catch or bolt.
This invention has special advantages in its application to freight-car doors, in that by the principal lever extending across or crosswise of the door great power or rcsistanceis secured thereby and it cannot readily be picked, while on the other hand, with a key in the hands of each depotagent, the door can be readily opened; also, in its application to cardoors, the principal lever may be curved or made in the are ofa circle, which would perrnit of thesecuring or locking of the door lower down, enabling it to more readily clear the top of the car in its movement.
This invention is also applicable for use upon doors in dwellings, as also in connection with blinds, gates, and barn-doors, having, among other advantages in its first-named use, to be out of the way, taking up no unnecessary room nor striking the furniture.
In the application of the invention to doors, single or double, for stores or dwellings or to gates the plate F is actuated by the foot. It can be used either with or without a weight, and cannot be opened either from the inside or outside, adapting it equally as well for prisons as for any of the aforesaid purposes.
