CDOOR-LOCKING DEVICE Application filed January 12, 1922. Serial No. %,651.

I To all whom it may concern:

Be it known that WILLIAM E. Wrnna citizen of the United States, residing at Toledo, in the county of Lucas and State of Qhio, has invented certain new and useful Improvements in Car-Door-Locking De vices, of which the following is a specification.

This invention relates to new and useful improvements in car door locking devices,

' and has for its primary object the provision of simple and efficient means for facilitating the closing of a hinged or drop door of a railway car. A further object of the invention is to form and arrange the mechanism by which the door is supported in closed position so that it is well suited for use in conjunction with a lever adapted to be fulcrumed upon the car side for the purpose of maintained in closed position.

whereof is pointed out in applying force to the door to cause it to be moved to closed position. Generally stated, the principal feature of the invention herein claimed consists inproviding the side of thecar with means adapted to form a fulcrum for a lever or prying bar which may be employed as a means for readily and quickly forcing the door to closed position, the said fulcrum means being independent of the said door and of the locking mechanism by which the latter is There are other features of the invention, residing in particular details and combinations of parts, as hereinafter appear.

While the features of construction herein claimed are shown in conjunction with certain other features of construction and ombinations of parts which are themselves the subjects of claims in othera plications for Letters Patent filed by me an now pending, it is to be understood that, except as otherwise specified in the claims appended hereto, the constructions shown in the .drawin a need not necessarily be employed in t5: practice of my invention.

In the drawings illustrating the referred embodiment of the invention, t e scope the claims,-

Figure 1 is a diagrammatic side view of a freight car showing mechanism embodying the invention applied thereto.

igure 2 is a detail side elevational view of a portion of the car, the free edge of. one

' of the doors and the locking devices for sup porting the door in its closed or locked position.

Figure 3 is a detail sectional view taken on the line 3-3 of Fig. 2,. looking in the direction of the arrows. I

Figure 4. is a detail view in side elevation showing a portion of the car side, one-half of adoor and one of the locking devices, the

door being supported in a partially closed position.

Figure 5 is a detail sectional view on the line 5-5 of Fig. 4 looking in the direction of the arrows, showing a levercooperating with the fulcrum and the door for forcing the latter to closed or locked position. The form of car illustrated in the drawings is constructed with sides 1 having the usual uprights or braces 2, a side sill 3, door 4 and a plurality of hinged drop doors 5, there being two of such doors on each side of the earn, In the construction here shown the door 5, it will be noted, is located below the level of the car floor, the latter being cut away, as indicated at 6, to form door openings.

Each door 5 is hinged to an adjacent center sill 7 of the car through the instrumentality of brackets 8 riveted to said-sill, the legs of the hinges being respectively secured to corresponding angle irons 9 which are and" its corresponding angle iron are shown,

but it is to be understood that each door is furnished with a plurality of each of said parts, as will be understood from Fig. 2.

The angle irons 9 extend nearly to the free edge of the door 5 where each is rigidly united to an arm or extension 10 preferably in the form of an, angle iron somewhat heavier per foot than the angle irons 9. As well shown in Figs. 3 and 5, the arms 10 extend downwardly and then roject outwardly beyond the free edge of t e door and the side sill 3, asindicated at .11, thus providing a ledge, seat or locking device adapt. ed to cooperate with a hook 12 for supporting the door.

Extending transversely of the door at its outer edge and secured to the under side thereof is a channel 14 whose lower flange 15 is riveted to the tops of the arms or extena sions 10 of the respective doors, the arms 10 thus being eilectively tied together and braced longitudinally of the car. Securely riveted to the channel and bearing against theinnerv face thereoffare brackets 16 which are respectively riveted to the arms 10 and the adjacent angle irons 9. By riveting one leg of each of the angle irons or projecting arms 10 to a bracket 16, and by riveting the other leg of said angle to the leg 15 of the channel member 14, the angle irons 10 are greatly stiffened inasmuch as the securing rivets pass through both legs thereof. By this construction an angle iron of less weight per foot may be employed than would otherwise be required to impart to the projecting arms 11 desirable stiflness and rigidity. By this construction also, it will be observed, the channel 14 forms a seat or abutment for the projecting arms 11, thereby enabling the latter efiiciently to resist the rotative' effort or bending strain imparted to them when the door 5 is locked and the car is loaded. Moreover, in such a construction the rivets through which the angle irons'10 are connected to the respective angle irons 9 are subjected to shearing stresses only and the maximum force is communicated to the angles 10 instead of to'the angles 9, which latter, as before stated, therefore may be of lighter section than the angles 10. It will be perceived that these features of construction result in the production of'a very rigid door which is reinforced by the before men.-

tioned angles 9, brackets 16, arms 10 and channel 14 and in which the outer portions or ledges 11 of the arms 10 are rigidly and effectively braced against the strains to which they are subjected when the door is in its supported position.

Where the door is hinged along the longitudinally extending center sill 7 it is subject to slippage, within the. limits of hinge clearance, when the car is subjected to heavy end impacts; and also by reason of the hinge clearance the closed door will be subject to.

, slight rotative or'twisting'movements in its own plane. In the structure illustrated, however, this latter movement is somewhat restricted by the construction and arrangement of the door supporting mechanism.

Moreover as the door, which is sturdily con structed and reinforced, is arranged so that its free edge, when closed, lies just inside and along the inturned upper flange of the side sill channel 3, which extends along the outer side of the car in the usual manner, and as the door supporting members are pivotally mounted upon the outer face of this channel and supportingly enga e the outer ends of the angles or arms 11, t e door supporting mechanism and the cooperating pasts of the door and car side, are associated 1n manner to main'tan the several parts in' serviceable condition even though subjected to severe abuse.

The supporting members which coo cratewith and engage the ledges 11 carried y the door are in the form 'of hooks 12 ivotally connected to corresponding housi gs 17 secured to theside 5111s 3 of the car. Each hook is preferably provided with a plurality of supporting shoulders or ledges 18 and 19, respectively, the former being an auxiliary ledge for temporarily supporting the door before it is finally closed, and the latter 19, being the final supporting ledge by which the door is sustained in closed position. As shown in the drawings, tliese shoulders or ledges upon the hook 12 are adapted to cooperate with the upper flange of the adjacent arm or ledge member 11 projecting beyond the free edge of the door. Mounted within each housing 17 to the rear of the adjacent hook 12 is a pivoted dog 20 designed to bear tightly against the hook and hold it in forward or locked position when said hook is supporting the door in its final or closed position. The housing 17 and the respective hooks 12, it will be observed, are oppositely disposed soethat the books, which respectively engage the upper leg of the ledges 11 of the arms 10, must be swung in opposite directions in order to release the door. It will be readily seen that by oppositely arranging the hooks 12 and correspondingly positioning the supporting ledges 11, the. door cannot shift either forwardly or rearwardlv when the hooks are in their locked positions and the dogs 20 are j ammed into place.

As is well known to those skilled in the art, the drop bottom doors of freight'cars may be easily lifted or raised to a partly closed position but much greater force is required to close them completely, not only because the proportionate part of the weight of the door that is not borne by the hinge increases as the door approaches closed posiposition, but also because the drop bottom causing it to extend outside of the clearance limits of the car when the door is being forced to closed position, it may be removed or disassociated from the car before the latter is shifted along the track.

The fulcrum or abutment for the door op- Y crating lever is formed on the car so as to be independent of the movement of the door and of the hook or locking means by which said dooris maintained in closed position.

Instead of shaping or arranging any of the major elements of the car structure in a manner to afford a seat or fulcrum for the door closing lever, the said fulcrum may be adnaeaeoe vantageously provided by rigidly securing to the side of the car, as for example, to the side sill 3 thereof, a plate or bracket 21 having therein an opening 22 through which may be passed any suitable bar or rod 23 forming a lever for cooperating with the adjacent edge of the door. In the present embodiment of the invention the lever23 is adapted to cooperate with the lower flange of the channel 14 extending along the edge of the door opposite the hinges thereof, the said plate 21 being located clear of the line of swing of the door and just outside of the position assumed by the free edge of said door when the latter is in closed position, the inner end of the lever thus being adapted to cooperate with the door approximately beneath its free edge and accordingly being capable of manipulation in a manner and direction for most effectively forcing th door shut. When the fulcrum means for a door operating lever are associated with a icar provided with drop doors and hooks operating in opposite directions, as shown in the drawings, the plate 21 forming a fulcrum is preferably arranged between the hooks of each pair thereof cooperating with the door. By

this means a single fulcrum plate or bracket 21 serves to'form a convenient fulcrum seat for the bar 23 when the door is being forced to locked relation with either of said hooks.

The operation of the locking device is exceedingly simple. When it is desired to close the door, it will first be raised by hand until the lower or auxiliary ledges 18 of the hooks 12 engage the ledges or seats 11 on the door. This engagement, of course, will support the door in a partially closed position, as illmtrated in Fig. 5. The bar 23 will then be insertedin the opening 22 of the fulcrum member 21 and be caused to engage the flange 15 of the channel 14 of the door. to raise the door and force it to its final closed position and the shoulders 19 of the books 12 will be forced under the ledges 11 of the door, thus holding the'door in its closed position. When this is accomplished the dogs 20 are swung from the position shown in Fig. 4 to their final position as shown in Fig. 2, thus retaining the books 12 in locked position. If the locking hooks em-v ployed are unprovided with the auxiliary ledges 18, the door may be preliminarily raised by hand until it can be conveniently engaged by the lever 23.

To open the door the dogs 20.are swung to a position permitting the release of the hooks 12 from the supporting ledges 11 and the said hooks are then knocked toward each other to allow the door to drop to its open position. The lever 23 may also be advano f the hooks.

The lever 23 will then be manipulated 2 door. Upon being applied through the ap- As will be readilyappreciated, it is often desirable where the doors are to be dropped to a completely open position to relieve the weight of the hooks somewhat so that they may be partially disengaged, the weight of the door being supported upon the extreme points of the main ledges or shoulders 19 If it is desired to lower the door from its support upon the main shoulders or ledges 19 and cause it to be supported by the auxiliaryor preliminary ledges 18 of said hooks, the lever 23 adords a convenient and edective means for adcomplishingwthat result.

rom the foregoing it will be perceived that simple, practical and efiective means are provided for readily closing the drop door of a freight car; that the locking hooks for the door are exceedingly strong and simple and eilicient in operation; that the door is Well braced to withstand the loads to which it is subjected; and that the door braces pro: vide locking seats or ledges for cooperating with the hooks, and that the latter are arranged in a manner to resist lateral shifting of the door.

Many slight changes may be made without departing from the spirit and scope of the invention.
