' 6 claims. (ci. 26e-44) This invention relates to improvements in door operating and locking mechanism in general and in particular to such a mechanism for'use on sliding car doors. l

In the majority orf-present day applications of locking and operating mechanism to sliding doors the locks and starting mechanisms are applied as separate structures and must be operated independently. In a few instances the llocking and operating mechanisms have beencombine'd into the one structure but these have in the main proved unsatisfactory due to their complicated nature or to the fact that they were not automatic in operation. It is an object, therefore, of the present invention to provide a door operating and locking mechanism which isfautomatically locked without a conscious effort on the part of the operator. l

A further object of the invention is the pron vision of a combined door opening, closing and locking mechanism which will become automatically locked when the parts are movedA in such a. direction as to close the door.

A still further object of the invention isV the provision of a combined door opening, closing, and locking mechanism which may be utilized to open or close the door or lock the door in a partially open position.

Yet another object of the invention is the pro-` vision of an improved door operating and locking mechanism in which all moving parts are permanently connected together thereby preventing A any possibility of loss of parts.

These and other objects of the .inventionrwill be apparent to personsskilled in the art from a study of the following description and accom-V panying drawing, in which Figure l is an elevational View of the improved operating and locking mechanism with the parts Fig. 4 is a sectional view taken substantiallyv on line 4--4 of Fig. 2l and with the operating lever indicated by line and dash outline;

Referring now to the drawing in detail, it' will be seen that thel improved door operating and locking mechanism has been applied to a railway car structure having a sliding door formed with panel 2 and front stile 4. Thefront stile is shown as of flanged channel formation with one Vflange adapted tol engageA within a sealing recess 6 formed adjacent the outer edge of a door framing angle memberf'l This kdoor framing member is secured to the door post IS which in turnk is secured to the 'sheathing IL and carries the Ill and lining I. course, obvious that the specic form of door or car structure' is immaterial and that the operating Aand locking mechanism now to'be de-y scribedV could be! applied to any structure using In the present instance the operatingand locking mechanism is carried by a bracket I8 riveted or otherwise secured as at to the 4car side wall structure adjacentl the door opening and so formed as to provide an outer surface 22 vcloselyl adjacent the plane of the door opening. The bracketV is also formed with a projecting portion 2d, provided with openings through which a rivet, bolt or other means 26 may extend. The bracket is also formed ,with a, stop 28 projecting outwardly fronithe surface BZirhme'diately' adjacent v the openings for pi'njf v The outer end of pin 25 hasgrotatably mounted thereon operating lever 3), formed; with a handleV portion'hhuo 32and`locking projection 36. The operating lever is also formed -with spaced ears B extending upwardly and rearwardly from 'the hub portion and formed at theirouter ends with an opening adapted to receive rivet or pin t by means of which the hasp 4i! is `pivotally connected tothe operating'levenv 'The innermost of the spaced 4ears has' formed thereonA adjacent the huhportion astop ll2"a`dapted` to cooperate with thestop 28 on the bracket and prevent more than' 90 degreesof rotation of the operating lever. The hasp, as previously stated, is pivoted at one end upon pin 33` between upstanding ears 36 of the operating handle and is formed on its outerv it is' desired to hold the door in either partiallyopened position or to permit greater movement of the door toward closed position under control of the operating mechanism, The hasp is also formed with a similar recess 43 intermediate itsv endsand which recess is adapted to engage the It v is,- orv hasp lug to hold the door in fully closed position or to permit movement of the door toward or away from closed position. The hasp is also formed with an opening intermediate its ends adapted to receive pin 50, upon the ends of which is pivotally mounted the locking link or dog; This locking link or dog is formed with spaced side portions `52 joined together adjacent their lower edge by a curved end wall 54 and by a projecting shroud wall 5E, As is clearly shown by the drawing, the projection 34 of the operating lever is formed with an inclined uppersurface 5S and a lower curved surface 60 which is adapted to engage with the curved end wall 54 of the locking link or dog, while the shroud wall 56 of the locking link overlaps the inclined surface of the projection. The projection 34 ofthe operating lever and the side walls 52` of the locking link or dog are formed with aligned openings 62 through which a suitable seal (not shown) may be inserted. It Awill be apparent that the shroud wall of the locking link or dog will prevent eX- cessive swinging movement of the locking link, while at the same time prevent unauthorized tampering or breaking of the seal in a position Where it could not be readily observed.

As shown in Figs. 1 to 3 inclusive, the hasp lug 46 is formed with an eccentric shank portion adapted to be engaged by the hasp and with the head portion 'I0 preventing the hasp from sliding otl the shankportion. The hasp lug is secured tothe door stile by means of a nut I2 threaded on the inner end of the lug. It will be obvious that by loosening the nut and turning the eccentric shank of the hasp lug adjustment may be obtained between the hasp and the door, thus insuring tight closure throughout the life of the car. Usually this adjustment is not necessary and in such cases the hasp lug may be made as shown in Fig. 7, in which case the lug is secured to the door stile cr other part of the door structure by riveting the inwardly projecting portion as at '14. In some cases it may be desirable to use a still further modied form of hasp lug as shown in Fig. 8. In this form the hasp lug with its head. is formed o-n a base plate 16 and the unit is attached to the door stile or other structure by means of countersunk rivets 13.

The operation of the mechanism is-as follows and assuming the parts to be in the position shown'by full line in Fig. 3: The operator will swing the locking link or dog upwardly to the line and dash position permitting the projection 34 of the operating lever to clear the lower wall 54 of the locking dog. Rotation of the operating lever upwardly through approximately 90 degrees will cause the parts to assume the position shown by full line in Fig. l with a powerful leverage being exerted through ears 36 to hasp 40 and through the hasp lug to the door, thereby causing,r it to assume a partially opened position. With the door in partially-opened position the operator can then lift hasp 40 free of the vhasp lug, thus clearing the door and permittingit tobe moved to fully opened position. If it is desired to lock the door `in partially opened position, then it is only necessary to lift the hasp off the hasp lug and engage opening 44 with the hasp lug and move the parts to the position shown in Fig. 3. When it is desired to close or lock the j door the parts will be moved from the line and dash position of Fig. 1 to the full line position, after which a counter-clockwise rotation of the operating lever will pull the door closed. During the closing of the door by rotation of the operating lever the inclined surface o1 the lever lug 34 will engage the lower wall 54 of the locking link or dog causing it to swing to one side and upon completion of the rotative motion of the operating lever this locking link or dog will swing back to the full line position shown in Fig. 3 thereby locking the door in closed position.

That the door is fully locked will be evident since the locking link or dog by engagement with the projection 34 prevents any relative movement between the operating lever and the hasp and any rotative movement of the operating lever in a direction to lift the hasp from the hasp lug is prevented by the stop 42 engaging the stop 2B of the supporting bracket as clearly shown in Fig. 3. Excessive rotation of the operating lever yin an unlocking direction is also prevented by this same lug 42 again engaging the stop 28 as clearly shown in Fig. l. It will thus be seen that the door is securely locked in either an open or closed position and that the same mechanism is utilized to force the door toward open position or to pull the door toward closed position. It will also be seeny that all moving parts are more or less permanently connected together thereby preventing any loss and that the parts are so positioned and arranged as to cause the locking link to automatically engagethe projection 34, thus automatically locking the door when the door is pulled to closed position. The operating mechanism has been shown as mounted on the car structure with the hasp lug carried by the door since this is the desirable position to prevent damage to the lock mechanism, but it is obvious that where desired the position of the part-s may be reversed and the lug placed on the car structure with the operating mechanism carried by the door. The only necessary requirement is that certain parts be carried by one of the relatively movable structures, while the other part is carried by the other of the relatively movable structures..
