. Application 516a July 10,1899.

To all whom it may concern.-

Be it known that I, LOUIS A. HOERR, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Oar-Doors, of which the following is a specification.

My invention relates to improvements in what are known as flush doors and parts used in connection therewith. The chief objects of my invention are, first, to provide improved means for preventing such doors from striking the car-siding while being opened; second, to provide improved means for closing such doors, and, third, to provide improved means for fastening them when closed. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is'a side elevation of a portion of a freight-car provided with a fiush door and embodying my improvements. Fig. 2 is a detailed plan view of a track-rail with hangers resting thereon. Fig. 3 is a vertical section on line 3 3, Figs. 1 and 2. Fig. 4 isadetailed vertical section on an enlarged scale. Fig. 5 is in part a side elevation of details illustrated in Fig. 4 and in part a vertical section of parts connected therewith. Fig. 6 is an enlarged front elevation of a detail of the door closing and locking mechanism. Fig. 7 is a front elevation of a detail of locking mechanism. Fig. 8 is a detailed vertical section on line 8 S, Fig. 7. Fig.9 is a detailed sectional view of a bracket and fastenings on line 9 9, Fig. 1. Fig. 10 is a detailed View of a horizontal cross-section on line lO 10, Fig. 6. Fig. 11 is a detailed sectional view on line 11 11, Fig. 6. Fig. 12 is a vertical section showing the parts illustrated in Fig. 11, combined with the fastening device shown in detail in Figs. 7 and 8. Fig. 13 is an isometric projection of a door'hanger. Fig. 14 is a rear elevation of a detail. Fig. 15 is a cross-section of the rub-knob shown in Fig. 16. Figs. 16 and 17 are enlarged front elevations of details. Fig. 18 is a plan view of the part shown in Fig. 17. Fig. 19 is a detailed sectional view on line 1919, Fig. 5. Fig. 20 is an enlarged detailed view, in front elevation, of a portion of the locking mechanism. Fig. 21 represents an improved corner bracket and guard. Fig. 22 is an isometric projection of a side bracket Serial No. 723,343. (No model.)

and guard. Fig. 23 is a view of a detail, and Fig. 24 is an enlarged view of a portion of the locking mechanism. I l, Similar letters refer to similar parts throughout the several views. A represents a portion of a freight-car, B the siding, C the doorway D a track -fillet, E a door-track shown secured in place by transverse bolts e and inclining outward for some distance back of its front end, as usual in flush-door tracks, and F a flush door, all of common form. The door F is shown provided with the usual center girth f, handle f, and rub-strip f Fig. 1. It is shown suspended from the track E by means of a front hanger G, Figs. 1, 2, and 13, and a rear hanger H. The front hanger G is of common form, except that the back thereof instead of con tinuing straight up from the plate 9, secured to the door, has a rear offset g above said plate g, which preferably brings the inner edges of the rail-bearings g in or near the plane bounding the inner face of said plate 9. This makes it practicable to arrange the front end of the track-rail substantially over the position occupied by the door when closed, which is found very advantageous in practice. The preferred form of hanger I1 is illus trated in Figs. 1, 2, 3, 4, 5, and 14, and is preferably provided with a body portion 11, preferably having a pair of upper returned hooks h, which embrace the head of therail E, i and lower inturned hooks h, which fit around the under edge of said rail. Between the hooks h a sheave H is shown pivotally attached to the body H of the hanger by the pivot-pin 7%. The hooks h each contain a vertical slot h (shown most clearly in Figs. 4 and 14,) and both are shown pierced by a transverse pivot-hole h The hanger H is preferably connected with the door F, as follows:

From the hanger-body H three links h h and h depend. They are shown pivotally attached to the hanger H by means of a pin h passing through their upper ends and the hole It in the hanger. The lower ends of the links if and h are each shown provided with an outwardly-projecting pivot-pin h".

1, Figs. 1, 3, 4, 5, 7, and 8, represents a bracket secured to the outside of the door F, near the upper rear corner thereof, by fastening t. In the preferred form shown this bracket has an outwardly-projecting pocket t'at its upper end, which rests in a socket in the face of the door F, Figs. 17, 18, 4, and 5. Below this pocket a loop 13 havinga vertical opening 6 is shown, and on each side of the bracket there is an outwardly-projecting lug i which in the form of my-device illustrated each contain a bearings 11 in which the pivot-pins h" of the links it and it turn. I prefer this form of pivotal connection between the links 72 and h and the bracket I, but do not confine myself to its use.

J, Figs. 1, 3, 4, 5, 6, and 19, represents a reciprocating bar or rod whose upper end is represented as tubular. In this tubular upper end the neck 3' of an inturned head J is shown secured. In the form shown this head is forked and may be conveniently formed of two pieces j, containing bearings 7' and fastened together and to the rod J bymeans of fasteningsj The centers of the bearings 7' are preferably back of the vertical plane cutting the center of the bearings 2' and an inturned head is preferably used, so as to give said. bearings the desired relative positions. The head J preferably enters the socket t' of the bracket I, as shown in Figs. 3, 4, and 5. The upper end of the bar J passes through the loop i which acts as a keeper.

The lower end of the link 72 is shown inserted in the fork j of the head J and is preferably connected to said head by means of a pivot-pin h whose ends rest in the bearings I find this a convenient construction; but there are many equivalent pivotal connections which may be substituted for it without departing from the essence of my invention.

With the construction above described the rear side of the door is furnished with a swinging support, which permits it to be swung into place and closed when desired, and the closing can be readily effected by forcing said rod J upward into the position shown in Fig. 4, and, on the other hand, when the bar J is allowed to drop the rear edge of the door swings outward into a position directly below the track E, when it can be slid back so as to leave the doorway open, if desired.

The lower end of the bar J is provided with a forked foot J Figs. 1, 3, and 6, preferably only differing from the head J, above described, in being turned to the rear side instead of inward and in extending down instead of up.

Between the armsj of the foot J the outer end of the short arm of a bell-crank lever K extends and is preferably pivotally attached to the foot J by means of a pivot-pin 70, Figs. 3, 6, 10, and 20. The lever K turns on a pivot Z (shown tubular) and may be secured in place by a bolt Z extending through. said pivot. The pivotl may form part of a casting L, which is preferably secured to the door F by means of bolts Z and a lug Z or other suitable mcans. By using bolts and fastening them on the inside of the doorF the removal of the casting without detection may be prevented.

The casting L is provided with a recess Z preferably substantially segmental in form, for the reception of an arm 70 projecting forward from the bell-crank lever K, as shown most clearly in Figs. 10 and 20. This arm prevents the removal of the lever K from its pivot, while its short arm 76 is coupled to the bar'J, for the reason that the casting L prevents the arm 70, hereinafter described, from being turned far enough back to permit the arm 70 to escape. I preferably make the outer end 710 of the arm 70 segmental, so that when in its lowest position it can take the strain of the pivot Z by resting against the bottom of the recess Z, and preferably arrange the pivot Z eccentrically, so as to allow the arm 70 to free itself as it rises, as indicated in dotted lines in Fig. 6.

The long arm 10 is provided at its outer end with a disk 70, preferably containing a central opening 10 which connects with an outwardlyextending slot I0 It is also preferably provided with a segmental flange 70', provided with a seal-wire opening k Within the flange k a segmental plate K is seated and turns. It is held in place by means of a pin 70, extending through a segmental slot 70 and whose head is large enough to prevent the plate from escaping. The plate K is shown provided with lugs 7t and 10 The former contains a seal-wire opening k and the latter being only useful as a thumb-piece for moving the slide K Said plate K contains a central opening 7e adapted to register with,

the opening 70 in the disk K of the lever K, and a slot 70 adapted to register with the slot 70 in the disk K. When the plate K is turned so that the slots and k register,

there is a free entrance to the openings 7& and la, and when the plate k is, on the. other hand, turned so as to bring the pin it in the neighborhood of the seal-wire opening 78 in the flange ft the slot 7c is covered by the plate K M, Figs. 7, 8, and 12, represents a swinging pin whose inner end is shown pivoted on a pivot m in a recess or pocket M in the siding B, so as to permit its other end to swing outward, and its outer end is provided with a head m. It is shown in a vertical position, in which it does not project beyond the side of the car, in Figs. 7 and 8, and in a horizontal position in Fig. 12.

The bar J is elevated and the door F closed by depressing the outer end of the arm 10 into the position in which it is shown in Fig. 1, and is lowered so as to allow the door F to swing open by elevating the arm 76* intothe position in which it is shown in Fig. 6.

When the arm 70 of the lever K is turned down into the position in which it is shown in Fig. 1, the point at which the foot J of the bar J is pivoted to the arm 70 of the lever K is preferably slightly farther back than the pivot on which the lever K turns, as indicated in said Fig. 1, and consequently when the door is closed its weight tends to keep the arm k in position, while the bracket L acts as a stop, preventing the foot J from moving farther backward. Consequently the 11111175 does not tend to move either up or down. If when in this lowered position the slots 7c and 74: are made to register, the pin M can be swung up through said slots into the central openings and 70 and may be fastened there by turning the plate K into the position in which it is shown'in Fig. 12. When in that position, the pressure of the lever K does not rest upon said plate, and consequently there is nothing to cause it to turn back, so as to release said pin M. When the pin M is thus locked in place, a seal-wire may be passed through the holes 70 and 70 and until the seal is broken the door cannot be unlocked.

N, Figs. 1 and 21, represents a rear corner door-bracket of common form, except that itis provided with an inner guard at, extending forward a portion of the length of the sole n and leaving an opening??? at the front inner corner, through which the rear lower corner of the car-door is intended to pass when swung in-' ward. This guard or rub-knob 'n is secured in place by means of the bracket, which is preferably secured to the car by means of fastenings n or other suitable means. The guard n is preferably made integral with said bracket.

N, Figs. 1 and 22, represents a side bracket and rub-knob or guard 7%, held in place by said bracket and preferably formed integral therewith. The guard 01 preferably differs from the guardn of the bracket N in extending substantially across the bracket. The bracket N may be secured to the siding by means of fastenings n passing through opening it in said bracket.

N Fig. 1, represents a door-bracket, which may be of common form.

0, Figs. 15 and 16, represents rub-knobs, each containing a perforation 0 for the passage of a fastening, and an inwardly-projecting wedge-shaped tooth 0, extending up and down above and below said perforation 0. These knobs are designed to be fastened in place by screws or other suitable fasteningand the projection 0 which is intended to be forced into the siding and designed to prevent the knobs from turning.

P, Fig. 1, is a stop of common form.

The position of the door when closed and locked is shown in Figs. 1 and 3.

The knobs O prevent the door from swinging against the side of the car either while being opened or after it is opened, and the brackets N and N prevent its swinging outward, and the stop prevents its escaping from the track E.
