DOOR-CHECK.
Application filed June 12,
To all whom it may concern:
Be it known that 1, WILLIAM A. Gnicnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Door- Checks, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.
lily invention relates to improvements in door checks and is more particularly de signed for use in connection with baggage car doors. 7
In the operation of railway cars, and more particularlybaggage cars, many accidents have heretofore occurred due to the sudden slamming ofthe side doors to closed position arising from sudden changes in the speed of tee car and while the baggageman has been standing in the doorway. The object of my invention is to provide a simple arrangement for positively preventing such accidents and more specifically to provide means for preventing accidental movement of a horizontally sliding door to closed position.
In the drawings forming a part of this specification, Figure 1 is a side elevation of a small portion of a freight car showing the door thereof and some of the immediately adjacent parts, and disclosing my invention in connection therewith. Fig. 2 is a vertical section taken on line 22 of Fig. 1. Fig. 3 is an enlarged detail of one of the door rollers and some of the adjacent mechanism. Fig. 4 is a vertical section taken on line 44l of Fig. 3. Fig. 5 is a vertical sectional view of a portion of the door check, the section being taken perpendicular to the axis of the roller and centrally thereof. In this figure the arrangement of parts corresponds to that which arises when the door tends to move toward closed position and indicates the manner in which the roller is chocked. Fig. 6 is a view similar to Fig. 5 but illustrating the condition of the parts when the door is moved in an opening direction during which the chocking block drags or trails behind the roller.
Referring to the drawings, the numeral 10 indicates a door jamb, 11 a threshold or floor, or the like, 12 a car door, 13 a track, 1% hangers suitably connected to the door as, for instance, by the bolts 15, and 16 Specification of Letters Patent.

rollers associated with the said hangers. One of said hangersas, for instance, that shown at the right in Fig. 1 of the drawing, may be of any ordinary construction employing any usual roller. lhe other hanger has my invention associated therewith. More particularly describing the same, the numeral 17 indicates a bracket appropriately secured to the car door, preferably at a point within easy reach of an operator standing upon the floor, and below said bracket a lever 18 is pivoted to the car door by suitable ineansas, for instance, the bolt 19, the said lever being provided with an operating handle 20 and a double cammed end 21 adapted to engage the vertical rod 22 which passes at its lower end through the bracket 17. The operation of the lever 18 in either direction will serve through the action of the cam 21 to lift the rod 22 for purposes which will be hereinafter made clear. The rod 22 is provided at its upper end with a perforation .23 through which a bolt 24 is passed to secure said rod to a lever 25 of a general rectangular shape, the same being provided at its under edge with the teeth 26 which are adapted to be engaged with the teeth of the rack 27 with which the track 13 is associated. The hanger 14 is provided with suitable perforations 28 near its upper end for the passage of the bolt 29, which serves as an axle for the roller 16. The said roller has in its periphery a groove 30 forming the flanges 31-31 on either side in order to insure the travel of the roller upon the raised portion 32 of the track 13. The block-like lever 25 is bifurcated, one portion thereof, as indicated at the numeral 33 in Fig. 4 of the drawings, passing on one side of the roller 16, and the other portion thereof, as indicated at 34 in Fig. 4; of the drawings, passing on the other side of the roller. Between the forked sections 33 and 34, the block 25 is provided with an arcuate surface 36 in alinement with the bottom part of the groove in the roller and which is adapted to engage therewith under certain conditions. Fig. 5 illustrates the manner in which said arcuate surface 36 of the block 25 engages with the roller to chock or frictionally brake the latter when the door tends to move accidentally in a closing direction as indicated by the arrow at in said figure. Fig. 6 illustrates the condition when the door is being moved in an opening direction as indicated by the arrow 6. In both of these figures the block 25 is in its lowermost position, that is, when the lever 26 is in its vertical position. By swinging the lever 20 and hence elevating the rod 22, the block 25 will be lifted and the braking or chocking effect on the roller thereby eliminated, when the door is forced toward closed position.
In operation, it is evident that the door may be moved to open position without difficulty, inasmuch as the teeth 26 of the brake element 25 will readily slip over the teeth during such movement, and also it will be evident that the braking element 25 does not act as a chock or brake on the door supporting roller in this direction since I leave a slight clearance, as indicated at lO, for the roller axle where it passes through the braking element 25, which will permit the element 25 to lag slightly behind the roller when the door is going to open position. Any tendency of the door to move toward closed position, however, will be automatically checked by the pawl and rack arrangement and also by the chocking action on the door supporting roller, as hereinbefore described. Consequently, to permit the door to move to closed position, the baggageman or other operator must actually manipulate the hand lever 20 so as to render ineffective the door checking means. In this way I positively eliminate the danger heretofore encountered of injury to the baggageman due to sudden and unimpeded movement of the relatively heavy baggage-car doors to closed position arising from sudden changes in the speed of the baggagecars.
I claim:
1. In a door checking device, the combination with a. track secured to the member having the door opening in a position above the top of the door opening, a door, a bracket secured to the upper part of the door, and a roller carried by said bracket and adapted to roll along said track; of a braking lever for said roller, said lever being pivoted to the bracket and extending to that side nearest the front edge of the door, said lever having a portion adapted to engage the roller between the latter and the track, said lever being freely movable a limited amount relatively toward and from the roller; means extending lengthwise of and adjacent to said track arranged to cooperate with said lever to automatically prevent movement of the latter in a direction corresponding to a closing movement of the door; and manually operable means for rendering said lever inoperative with respect to said first named means, said door being always freely movable in an opening direction.
2. In a door checking device, the combi nation with a track secured to the member having the door opening in a position above the top of the door opening, a door, a bracket secured to the upper part of the door, and a roller carried by said bracket and adapted to roll along said track; of a braking lever for said roller, said lever being pivoted to the bracket and extending to that side nearest the front edge of the door, said lever having a portion adapted to engage the roller between the latter and the track, said lever being freely movable a limited amount relatively toward and from the roller; means extending lengthwise of and adjacent to said track arranged to cooperate with said lever to automatically prevent movement of the door; and manually operable means for rendering said lever inoperative with respect to said first named means, said door being always freely movable in an opening direction. said second named means comprising a rack having teeth cooperable with a shouldered portion of said lever.
In witness that I claim the foregoing I have hereunto subscribed my name this 28th day of May, 1919.
WILLIAM A. GEIGER.
