To all whom, it may concern.-
Be it known that we, JOSEP J. VORHES and HIRAM ORISMAN, citizens of the United States, residing at Seneca, in the county of Nemaha and State of Kansas, have invented certain new and useful Improvements in Car- Doors, of which the following is a specification.
This invention relates to improvements in doors for railway freight-cars, and especially to that class of doors known as graindoors, inasmuch as they are especially adapted for use in connection with grain loaded in bulk.
The especial objects of the improvements which form the subject-matter of this application are the production of grain-tight doors of simple, durable, and economical construction, which are easily operated in closing or opening, in which the weight is sustained by iron rods in a manner that facilitates the movements of the doors, in which quicklyoperated locking means are provided, in which the doors can be readily swung out of position when not in use, in which the doors cannot become detached and lost, and in which various advantages are conserved not necessary to mention, because apparent to those skilled in the art.
In the accompanying drawings, which form a part of this application, Figure 1 shows in side elevation a portion of a graincar equipped with our doors, the latter being shown in closed and locked position. Fig. 2 is a view of the parts shown in Fig. 1 as they appear from within the car. Fig. 3 shows the doors in an opening position. Fig. 4 shows the manner of removing and suspendingthe doors. Fig. 5 is a fragmentary detail showing a door folded up against the carroof.
Referring to the details of the drawing, A represents one of the side walls of a box-car of ordinary construction, in which there is the usual opening or doorway a.
B B represent, respectively, the doors or door-section's, which together form a closure for the opening a and for the purposes of this description will be respectively designated as the outer door and the inner door. As shown, these doors are built of two courses of boards laid at right angles to each other, secured together in any preferred.
manner and reinforced along their bottom edges with iron wear-plates; but it will be understood they may be constructed entirely of metal, if desired. When in closed position, these doors are arranged so that the forward edge of the outer door overlaps the inner door a foot or more, thus forming at the center of the doorway an overlap-joint, which contributes to the tightness of the closure. The forward edge of the inner door is detachably interlocked With the outer door by the hook-bars b, which are rigidly bolted to the door B and engage the U-shaped members b which are correspondingly secured to the inner face of the door B, as shown in Fig. 1. The forward edge of the outer door is detachably interlocked with the outer face of the inner door by a locking-bar 6 which is partially rotatable in sockets b fixed in the door B and projecting outwardly therefrom to form bearings for the outwardly-bent portions b of the locking-bar. The lower end of the locking-bar is bent horizontally to form a handle I), by which the bar may be readily turned in its bearings. Means may be provided whereby the handle may be locked; but as such means form no part of this invention they are not shown. The locking-bar is engaged by the horizontal hook members 6 which are rigidly secured to the door B and have their hook portions extending beyond the edge of the door and passing below the lockingbar. U-shaped members If, rigidly secured to the door B, also engage the locking-bar by having their projecting portions bent downwardly, so as to overlie the bar. The latter is therefore embraced on both sides by b and 6 thus forming double interlocking means, the efficienoy of which will be apparent.
At the center of each of the doors and on opposite sides thereof square sheet-iron plates 6 are securely bolted. Vhere the doors are of metal, these plates may be dispensed with, as their function is to furnish suitable reinforced bearings and attaching means for the hanging-rods and their connections to be described. Rotatably mounted in the plates b and projecting from the inner faces of the doors are eyebolts b 12 which are engaged by eyes formed on the lower ends of the hanging rods 1), the upper ends of which are furnished with eyes which engage the eyebolts a fixed in the upper frame-timbers of the ear, each bar and its connections thus providing a swinging support for a door which freely permi ts the various movements and adjustments incident to the operation of the latter. On the squared portion of each eyebolt b is mounted a ratchet-plate 6 which is formed with a handle I) and is adapted to be engaged and held by a pawl b, pivoted on the plate 6 This ratchet-plate has a twofold function in that by turning the eyebolt b on its axis it adjusts the latter to thelength of the bar I), thus maintaining the latter at a position of greatest efliciency relative to the door, and when in the opening of the doors the doors are raised, as shown in Fig. 8, they will be held in such position by turning the eyebolts from the position shown in Fig. 2 toward the outer edge of the doors, all of which will be readily apparent.
At the upper and inner corners of the doors we bolt square sheet-iron plates b, in which are rotatably mounted eyebolts b, the eyes of which are loosely engaged by eyes on the lower ends of the bars 0 the upper ends of which are loosely engaged by eyes in brackets. (1 which are so secured to the overhead framing-timbers of the car as to stand outwardly from the timbers a sul'licient distance to permit the doors to swingfreely under the bars, as shown in Fig. 4. To facilitate the movements of the members 6 b, we preferably bevel or chamfer off the corners of the doors, as at b.
When the doors are not in use, they are hung at the inner side of the car by hooking the members 1) of door B into the members a secured to the overhead car-framing and the members I) of door B over the hooks a,
or they may be swung up to the car-ceiling and held by the hangers (L as shown in Fig. 5.
To set up the doors in operative position, they are unhooked from their respective keepers a, a, and a and are allowed to swing down, the rods b sustaining their weight into the position shown at the right hand of Fig. 4. The operator brings each door to an upright position (shown in Fig. 3 with their edges overlapped) and hooks together the members b" b. He then pushes inwardly the projecting edges of the doors until they are parallel, when he turns thelocking-barin its bearings, thus bringing the portions be tween the bends b under the members 6 and over the members I), as shown in Fig. 1. To open the doors, when used as grain-doors the operator reverses the movement of the locking-bar, whereupon the outward pressure of the grain in the oar-will push the doors to the position shown in Fig. 3, thus forming a triangular opening at the bottom of the doors, through which a portion of the grain passes into a suitable receptacle arranged therefor. When the pressure is relieved, the
operator unhooks the members I) I9 and swings the doors into the positions shown inv Fig. 4.
It, will be noted that when the doors are closed the bars I), being substantially in vertical alinement with the eyebolts, resist any vertical movements of the doors incident to the j olting of the cars and that lateral movements are resisted by the bars I), thus effecting practically grain-tigl1t joints when considered in connection with the pressure of the grain within the car. It is manifest that the same doors, if made to fill the doorway a, would form an el'lective closure for any kind of freight-car and with a suitable lock on the bar 6 would form a greater protection against car-burglary than most of the horizontally-sliding doors in common use.
Various modifications may be made in the details of the invention herein described, without departure from its principles. Hence we do not wish to be limited in our patent to details; but
