DAVID S. COOK, OF COLUMBUS, OHIO.

CAR-

DOOR.

SPEGIFICATION forming part of Letters Patent No. 423,739, dated March 18, 1890. Application filed MarehS, 1889. Renewed February 21 1890. Serial No. 341,287. (No model.)

Be it known that I, DAVID S. COOK, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Car-Doors, of which the fol lowing is a specification. My invention relates to the improvement of freight or box car doors; and the objects of my invention'are to so connect the door with the car or support it therefrom as to admit of its being closed into the door-frame until its outer surface is flush with the outer side of the car, to provide the car and door with means whereby the door may be closed into the frame by leverage-power, to obviate the use of a lower door-track on theouter side of the car, to so support said door when open as to prevent its binding against the car, to readily and easily open and close the door, and to accomplish these objects in asimple and inexpensive manner. These objects I accomplish in the manner illustrated in the accompanying drawings, in which1 Figure 1 is a side elevation of a portion of a car, showing the door closed. Fig. 2 is a horizontal section taken on line 00 wof Fig. 1. Fig. 3 is a vertical section taken on line y 3 of Fig. 1, showing the door open and in positionfor closing. Fig. 4 is a similar sectional view showing the door closed, and Fig. 5 is an inner side view of the door-frame and door.

Similar letters refer to similar parts throughout the several views.

a represents acar, the frame-work of which is of the usual form.

I) I) represent the usual vertical door-frame posts, and c thelongitudinal beam passing over said posts, and forming the upper side of the door-frame, formed in the usual manner.

d represents a horizontal section of the track-bar supported from the outer side of the car in a line above and to one side of the doorway.

cl represents a second section of the trackbar, the inner end of which is horizontally opposite and in line with the inner end of the track (1, although a short distance therefrom. The track d is inclined inward from said inner end, and has its outer end meeting the face of the car at apoint opposite the inner side of the frame-postb. These tracksections are connected with the side of the car by means of supporting-arms e. Extend.- ing between the opposite inner ends of these tal arms (2, each provided with a central slot 6 Extending between these arms 6, and having its ends resting and adapted to slide within the slots 5 is ashort bar f. This bar and has secured to or formed on its front side a short section of track-bar 9, said section being of such length as, when the bar f is in the front ends of the slots 6 to fill the greater portion of the space between the inner ends of the track-sections d (1, thus forming a detached continuation of the latter. Pivotally secured to the lug f of the slid ing barf is the slotted upper end of an arm h, the remaining end of which is rigidly sethe inner side of the door frame through which it passes loosely.

70 represents the door, which is of the ordi nary form. I Secured to the outer sideof the door 7c, at the upper end .thereof, are the lower portions of two upwardly-extending hangers Z, consisting of metallic bars bent outwardly from the face of the door, thence upwardly, inwardly, and again downwardly to form hooks, which engage, when the door is open, with the track-section d, and'support the door therefrom in the position shown in the dotted lines of Fig. 1 of the drawings.

Supported, as shown, from the inner side of .post 1),

parallel with the inner'face thereof, is a trackbar n. This track-bar n is adapted to rest and slide within a metallic block m, so shaped as to partially embrace said track, and having projecting from its rear side a lug, to which is pivotally secured the slotted end of a short arm p, which has its remaining end rigidly connected with one end of a horizontal rod q within a depression or mortise q, formed within the front and inner side faces of the fram e-post b. This rod q, passing loosely through said post I), has its remaining end rigidly secured to an arm 'r', extending inward at an angle with the position of the arm 19. The inner end of the rod 1' is, as detrack-sections and the car-siding are h0rizonf is provided on its rear sidewith a lug f,

cured to a horizontal rod 1', projecting from the door It, near the lower end thereof, and

IOC

connected beneath the car with a lever to, therear end of which is pivotally connected with a pin o, made to project outwardly from the I lower frame-work of the car. '10 represents a short metallic strap or bar, having one of its ends secured to the outer side of the car at apoint opposite the post Z),

and near the lower portion of the doorway,

, the remaining end of said bar being made to I project outward a short distance over said doorway.

. sufliciently to allow it to pass behind the pro-.

beam to receive the arm h and lug f.

The operatlon of my device is as follows:

The door being open, it is supported uponthe track-section cZ, said track-section being supported at such distance from the car as to prevent the contact of the door therewith. The door is further assured in its position by having its inner and lower track at sup ported within the block 1%, which is supported, as hereinbefore described, in front of a depression or mortise q of the frame-post b. It being desired toclose the door, the latter is pushed forward until the hanger Z nearest the doorway haslpassed over the movable track-sectiong and over the section OZ? until the remaining hanger Z is upon the movable section 9 and the door is opposite the doorway. Owing to the incline of the track-bar d, it will beseen-that when the door is opposite the doorway that side of the door nearest the frame-post Z7 will be drawn inward jecting end of the strap w. By pressing downward upon the lever to the rod Z'will be made to descend, which movement, through the arm 3, rod t', and arm h, and the connection of the latter with the movable track 9, will operate to draw said movable track-section and the door supported thereon inward, said door entering the door-tram e,which is cutaway about itsouter side to receive said door until the latter is flush with the cansiding. A recess y is formed in the front side of the horizontal The above-described downward movement of the rod t will also operate, through the arm h, rod q, arm 10, and the connection of the latter with the block on, to force inward the lower part of the door. 7 It will be seen that any tendency of the door to be elevated when drawn inward will be obviated by having the pivot-pins which connect the track-sections g and arm hand block m and arm 19 passing through slots formed in said arms h and p.

' The door-may be opened by pressing upward on the lever at until the door is forced out ward to the position shown in Fig. 3 of the drawings, when it may be pushed back to its position upon the bar d, as hereinbefore described.

By the above-described construction it will be seen that the door will be so supported as to prevent its binding against the car.

It is well known that door-tracks supported along the lower portion of the car-siding often become bent or broken, from contact with wagonsor passing cars, and thus prevent the opening or closing of the door. This difliculty, it will readilybe seen, will be obviated by the construction herein described, wherein no outward projections appear on the lower portion of the car.

' I am aware that inclined door-tracks have been used heretofore, and therefore do not c1aim,broadly, such incline. I

' Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

1'. The combination, with the 'car, horizontal track-section (Z, and inclinedtrack-section (1, supported from said can and intervening movable section g, supported in slotted arms 6', of the door 70, supported by hangers Z, and made to slide on said track-section, substantially as and for the purpose specified.

2. The combination ,with a car and its framework,, the latter having recess y, and having g supported therefrom horizontal track-section cZ, inclined sectional, and movable track-section g, supported in slotted arms e, and door it, having hangers Z, made to engage'with and slide on said track-sections, of the slotted arm h, pivotally connected'with said movabletracksection, arm 5, rigidly connected with arm h by rod 1, approximately vertical. rod t,'having its upperend pivoted to said arm 3, and having its lower end projecting through the car-floor and pivotally connected with lever u, the latter also pivoted to the car frame-work,,substantially as and for the purpose set forth.
