To aZZ whom it may; concern.'

Be it/known that l, STAGY B. l-lAsnr/rmn, a citizen of the United States, residing at Chicago, in the county of CookV and State ,of Illinois, have inventedv a. 'certain new and useful Improvement in Door Operating and Locking Devices, ot which the following is a Jfull', clear, concise, and exact description,y

reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in door operating and locking devices.

One object of this invention is to provide a simple, eiiicient and inexpensive device which is applied to a door 'of the sliding type and which has effective means for eitherl drawing the door tightly closed or starting .the opening operation thereof and which also serves asp-a device for locking the door either tightly closed or in partly opened position.

More specifically an object of this invention is to provide a device of the character described, wherein toggle lever operating mechanism is 4employed to force the door to tightly closed position or start the opening operation thereof.

In the drawing forming a part of this specification, Figure 1 is a side elevational view ofva portion of a box car, showing a portion of the sliding door. thereof with my improvements in connection' therewith. Figure 2 is a horizontal, sectional view cor-v responding substantially to-the line 2-2 of HFigure 1, Figure 3 is a view similar to Figure 2 showing in full/lines the position of the parts with the door partly opened 'and illustrating in dotted lines the position of the parts when the `door is locked in partlyopened position thereby. And Figure 4 is a vertical, sectional view corresponding substantially to the line 4 4 of Figure l.

In said drawing, 10 denotes the Vsliding side `door of: a railway box car and 11 the side wall of said car.` One of the doorpostsis indicated at 12 in Figures 2 and 3, the same being Vcut away at its outer side to provide ,a door stop 13 against which is adapted to bear the front edge of the door when the same is in fully closed position.

The improved door operating and locking device, as shown, comprises, broadly, a bracket A; a bearing plate B; a link' supporting member C; a Strap D; a link E; an

(perating handle lever F,- and a latch plate rlhe link supporting member C is in the formo a relatively heavy rectangular plate having an inner ilat face bearing on the plate B interposed between the same and the outer side ot' the door. rlhe bearing plate B is of substantially square outline, as clearly shown in Figure 1, and is fixed to the door by means of screws or any other suitable securing devices. The plate B is of such a. size as to provide a full bearing surface for the plate C in all operative Vpositions thereof. At the side opposite to that abutting the plate B, the plate C is formed with .a cylindrical boss 15 spaced inwardly from the end of the platejand working in an opening 16 provided in an outwardl oii'set portion 17 of the strap D, the stra being horizontally disposed and secure to the door by means of a pair of bolts 1818. The plate C-is rotatably mounted on the bearing plate Bby a bolt 19 extending centrally through the boss 15, the plate B and the door 10, and projecting through the opening 16 of the plate D, a washer 20 being interposed between the head of the bolt andthe outer side of the oii'set portion 17 of the strap. At the free end the plate C is provided with an outstanding lateral enlargement 21 of substantially cylindrical i form extending transversely of the same.

The enlargement is provided with. an axial bore adapted to receive a pivot in 22.

The link E comprises a pair o parallel longitudinally disposed central web 24 having its opposite edges spaced inwardly from the corresponding ends of the arms. The projecting portions of the .arms at one end of the link E are disposed on opposite sides of 4spaced arms 23 connected by an integral'y the projection 21 and are providedA with alined openings adapted to receive the pivot pin 22. The link is thus pivotally connected to the supporting member C, the projecting opposite ends of the pin 22 being headed over to retain the parts in assembled relaltion. The projecting portion of the arms 23 at the opposite end of the `link E are also provided with alined pin receiving openings 25. i

The operating lever F is in the form of an elongated bar having a hand'grip `26V formed at the ree end thereof. From the inner end of the hand grip toits opposite end, the lever is composed of two longitudinally extending, spaced parallel sections S27-27, the free ends of the sections being connected by a transversely disposed, cylindrical fulcrum member 28 formed integral with the sections. A second transversely disposed, integral connecting member 29 is disposed between the sections 27 inwardly of the fulcrum member 28. The member 29 has a fiat face 30 disposed in a plane substantially at right angles to the longitudinal axis of the lever and a flat face 3l at the opposite side thereof inclined with reference to the face 30. The member 29 is laterally extended beyond the plane of the side of the handle portion of the lever, and each section 27 is laterally enlarged to correspond therewith as indicated at 32 thereby providing an offset portion in each section. As clearly shown in Figures 2 and 3, each of the sections is tapered from the offset portion to the fulcrum end of the lever, thereby providing a side edge 34 inclined with reference to the longitudinal axis of the lever. The projecting portions of the arms 23 at the end of the link opposite to its connection with the plate C embrace and are pivotally connected to the offset portion of the lever F by a pivot pin 35 extending through the oiiset portions 32 of the sections 27, the member 29 andthe openings 25. It will be evident that the lever and link E are joined in the manner of a toggle and that the link E is pivotally connected to the lever at one side of the longitudinal axis thereof. To limit the relative movement of the lever F and the link E so as to prevent the toggle from being straightened, the web 24 of the link E is provided with a laterally projecting lug 36 having an inclined face adapted to form an abutment coacting with vthe correspondingly inclined edge 34 of the lever F.

The stop bracket A is in the form of a plate applied to the door sto 13, the same aving three spaced lateral anges 37-37, two of which extend along the front and rear edges of the door stop 13. The third iiange serves as a brace between the plate and theside wall of the car, as clearly shown in Figures 2 and 3. At the lower side the plate is provided with an inwardly offset portion 38 adapted to lie flat against the side Wall of the car, the same being secured to the-side wall by a bolt or any other suitable device. The bracket A is also secured to the door stop by means of bolts extending throu h the plate portion thereof. Adjacent t e upper and lower edges of the plate outwardly projecting flanges 39 are provided, the same being spaced apart a proper distance to loosely receive the lever F and the link E therebetween. iAs clearly shown in Figure 4, the lates 39 are curved at their outer ends, there y providing a Haring opening ,facilitating entrance of the link and lever therebetween. The lower flange 39 extends longitudinally beyond the upcper iiange as clearly shown in Figure l an is provided at its outer edge with a relatively short upstanding flange 40. The upper surface of the lower flange 39 is also provided with a transversely disposed rib 41 connecting with the flange 40. Between the iianges 39, the flat portion of the bracket A is provided with a pair of outstanding spaced projections 42 and 43 adapted to coact `with the fulcrum member 23 of the lever F. The projection -11-2 is cut away at its inner side as indicated at .44, thereby providing a rounded bearing surface for the fulcrum member 28 and an overhanging hook portion preventing disengagement of the fulcrum member from the projection. The projection 43 is provided with a substantially straight inner face 45 adapted to coact with the fulcrum member of the lever. It will be noted that the bearing surface of the projection 42 and the surface 45 of the projection 43 are spaced apart a greater distance' than the diameter of the fulcrum member 28, thereby permitting limited movement of the member 23 within the opening between the projections. The overall distance between the outer sides of the projections 3 and 44 is slightly less than the opening provided between the face 30 of the member 29 and the inner end of the handle portion of the lever. F, so that the lever may be placed in position over the lugs which are entered into the opening, the same acting as a locking means to prevent movement of the lever in a longitudinal direction.

The latch plate G is provided with an opening 46 at its upper end adapted to receive a bolt 47 whereby it is pivotally connected to the upper portion of the bracket A. The plate G is adapted to swing in a vertical plane and is of 4such a length as to extend behind the flange 40 when in its depending position. Along the edge of the plate Gr adjacent the rib 41, a vertically extending flangc 48 is provided adapted to abut the rib 4l and limit the swinging movement of the plate. At its lower end, the plate also has a horizontally disposed flange 49 provided ywith a lock' receiv1ng opening 50. The lower flange 39 of the bracket A is provided with acorresponding lock receiving opening, with which the openin 50 is adapted to belalined when the plate is .disposed in the full line position shown in Figure 1. Alined openings in latch G and lower flange 39 are also provided forreceiving the usual car seal.

Assuming that the parts are in the position shown in full lines in Figures 1 and 2 of the drawing, when it is desired to open the door, the following sequence of operations are performed. The seal is first removed, after which the pivoted plate G is llO swung upwardly to the dotted line osition shown in Figure 1. The operating ever F is then swung` outwardly, thereby causing the same to swing on its pivotal connection with the link E until the fulcrum member 28 engages with the face 45 of the projection 43, whereupon the lever will swing upon the fulcrum as.'y a pivot pushing the door open until ity reaches the position shown in full lines in Figure 3. It will be evident that during this operation, the lever and link act as a toggle mechanism thereby greatly multiplying the force applied during the initial portion of the operation. rIhe movement of the lever in the door opening operation will be arrested by engagement of the edge 34 with the fiat front face of the plate portion of the bracket-A.l When the door has thus been opened, the fulcrum4 member is disengaged from between the projections 42 and 43 and'dropped to the dotted line position shown in Figure 1, the plate C turning freely on the plate B and the lever savinging on its pivot 35 under the inuence-of gravity. If it is desired to lock the door in the partly opened position `iin-Figure 3,A

the lever is swung on the pivot 35 until it assumes the dotted line position shown 1n Figure 3 and is engaged over the projections 42 and 43, the link E resting on the lower.

fiange v39 of the bracket A, thereby supporting the lever F. The pivoted plate G is then swung from the dotted line position shown in Figure 1 to the full line position, thereby holding the lever securely in place. The parts may then be properly sealed by fastening the usualcar seal within the openings in the member G and the flange 39. When it is desired to close the door, the latter is moved to a pointes near the door stop 13 as can be conveniently done by the operator, which may be substantially the position shown in Figure 3. Thereupon the operator swings the handle from the dotted line position shownl in Figure 1 to a horizontal position and enters the fulcrum member 23 into the space between the projections 42 and 43. Upon pulling the handle end of the lever outwardly, the fulcrum member 28 will be brought into engagement with the curved bearing surface on the inner side of the projection 42 where, upon lfurther movementv of the lever F, the same will pivot on the fulcrum member 28 thereby drawing the link E toward the stop 13 and pulling the door closed, which position is indicated in full lines in Figure 2. As hereinbefore pointed out,l movement of the lever F relatively to the link E will be limited by engagement ofthe inclined face of the lever with the lug 36 on the link, thereby preventing the toggle from being overthrown and straightened out. After the lever has reached the position shown 1n Figure 2, the latch G is dropped 1n front of the same andV theusual ear seal appliedthrough the registering openings of the plate G and the ange 39.

` Although I have herein shown and described the plate A as secured to the door post and the other parts as fastened to the door, it will be understood that the position door and including a `hand operating lever movable in a horizontal plane engageable withsaid abutment to hold the door in fixed position; and means for locking said lever to said abutment when engaged therewith to hold the door in closed position.
