Patented Feb. 18, 1930 UNI-TED vstares PATENT OFFICE FRANK DITCHFIELD, OF CLEVELAND, OHIO, ASSIGNOR TO THE YOUNGSTOWN STEEL noon COMPANY, or 'crnvnnann,

OHIO, A CORPORATION OF OHIO noon LOCK AND ornna'ron Application filed April 28,

This invention relates to improvements in door lock and operator, and, more specifically, to such a door lock and. operator as is particularly adapted for horizontally slidable doors ofthe box car type.

One object of the invention is to provide a door lock and operator of the lever type wherein relatively high leverage is effective in the most efficient manner for forcing the door during the last part of its closing movement and during the. initial part of its opening movement.

Another object of the invention is to pro vide a combined looking and operating device including-a hasp so arranged that the hasp may be readily pried E of its staple by the operating element so as to facilitate openlng of the door in the event of binding between the hasp and its staple.

Another object of the invention is to pro vide a combined lock and operator of the type above indicated whereinthe locking. means and the operator proper may be applied as a single unit.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specification, Fig. 1 is an elevational view of a portion of a box car showing my improvements applied to the side door thereof. Fig. 2 is a. vertical sectional view corresponding to the line 2-2 of Fig. 1. In this figure, the dotted line posit-ion of the lever indicates the position assumed when releasing the hasp from its staple; Fig. 3is a horizontal sectiona1 view corresponding to the line 33 of Fig. 1. Fig.4 is a detail vertical sectional view of the locking means corresponding to the line H of Fig. 1. And Figs. 5 and 6 are views corresponding to Figs. 1 and 2, respectively, showing another embodiment of the invention.

Referring first to the construction illustrated in Figs. 1 to at, inclusive, the side wall of the box car is indicated at 10, the same having a door opening defined in part by a front door post 11, said opening being adapted to .The door which I have chosen for illustration is of the sheet metal ing 21 adaptin the hasp casting is secured to the :tension 28 has a head at its 1923. Serial No. 273,477.

the details of the front edge of which that is entered through an opening in the ridge of the vertically extending corrugation 18 of the door and by which the fastener is effectively interlocked with the door.

In carrying out my invention, I employ a hasp designated generally by the reference character A; a locking means indicated generally by the reference character B; and an operator C. I

The hasp A is pivotally connected to the loop 16 of the fastener above referred to, said hasp A being relatively elongated and having an arcuate end 19 normally extending upwardly and the free end of which has an opening or recess 20 for the purpose hereinafter described. Intermediate its ends,the hasp or link A has a longitudinally extending opento be positioned over the staple 22 or the locking device proper B. Said staple 22 is preferably formed integrally with a casting having a base section or web 23, an outwardly offset web or housing section 24 and a laterally extended flange 25. Said car side by any suitable means such as rivets or bolts indicated at 26. The outwardly ofiset housing or web .2 1 has a vertically elongated slot 27 therein in which is suitably mounted a lateral extension 28 on the locking pin 29. Said exinner end, as shown in Fig. 4, thereby preventing the looking pin 29 from becoming disassociated from the securing casting when the latter is in place on the car side. The pin. 29 has its lower end 31 adapted to enter a slot 32 provided in the staple 22 on the outer side of the hasp A when the latter is in locked position.

The pin 29 is also preferably provided with a lateral extension 33 which is positioned closely adjacent the staple 22 when the looking pin is in operative position, said projection 83 having a small opening or recess 34 therein aligned with the opening 32 in the staple and adapted to receive the band of the usual type of railroad seal.

In the form shown in Figs. 1 to 4, the lateral extension 25 of the mounting plate is formed with an integral boss or fulcrum 35 projecting horizontally outwardly therefrom, as shown in Fig. 2. The operating lever C is loosely pivotally mounted on said boss, as shown in said Fig. 2, the opening 36 in the lever for this purpose being preferably outwardly flared, as shown in Fig. 2. At its upper end, the lever C has a relatively short extension or bar 37 which maybe slight- 1y rounded, as indicated at 38, the rounded edge forming a fulcrum for the lever C when the lower or handled end 39 thereof is pulled outwardly, as shown by dotted lines in Fig. 2. In this operation of the lever C, the lateral extension plate 25 serves as the bearing for the lever in any angularly adjusted position that the latter may assume, as shown in Fig. 1. The lever C is retained on the boss 35 by any suitable means, such as the washer i0 and rivet 41.

Intermediate the point of its pivotal support and the handle end proper, the lever C is provided with an outwardly projecting rounded lug 42 having a somewhat enlarged ilange 43 at its outer end. Said lug 42 is of such size as to'enter the opening or recess 20 in the hasp A and, after being entered, the flange 43 will slightly overlie the surface of the hasp or link A and prevent accidental aisengagement.

Assuming the parts in the position shown in full lines in Fig. 1, my improvements are utilized as follows. After breaking the train seal, the locking pin 29 is lifted vertically so as to be disengaged from the staple 22. It frequently happens that the hasp binds very tightly on its staple, due to slight shifting of the door or weaving of the car parts while in motion and it has heretofore been difiicult, at times, to properly release the ordinary hasp from its staple. WVith my improvements, any

such diflicultyis easily overcome by the operator merely pulling the lever C outwardly at its-lower end to a position such as indicated by the dotted lines in Fig. 2. Ample leverage is thus provided to forcibly loosen the hasp or link A-from'the staple 22. After the hasp has thus been disengaged from its staple, the lever C is swung to the dotted line position in Fig. 1 so as to bring the stud 42 thereon opposite the opening 20 in the link, whereupon the free end of the link is applied over the lug 42, as will be understood. The lever C is then swung in a counter-clockwise direction, thus forcibly starting the door in an opening direction. Attention is called to the fact that the hasp or link A is so curved at its free end and the lug 42 is so located on the lever C that the line of applied force or substan- -dent that the lever D is tially directly, horizontally in line with the point of attachment between the hasp and the door, thus obtaining the most effective application of the force to the opening of the door at the beginning of the opening movement, at which time the greatest force is desirable. After the door has been partially opened, the lever and hasp are disengaged, as will be understood. The final closing of the door is accomplished by the hasp A and lever G by detachably locking the same and swin ing the lever C to the left, or clockwise, as wi 1 be understood. In the locked condition of the parts, it will be observed that the pin 29 locks the hasp A and the latter in turn overlies the lever C so that it cannot swing outwardly from the car side. It will further be observed that all parts of my improved combination, with the exception of the hasp proper, are adapted to be applied to the car side as a unit, thus not only minimizing the cost of labor but assuring lever to the locking device proper and hence with respect to the hasp when it is brought into play.

Referring next to the form of the invention shown in Fig. 5, the arrangement of door retainer, hasp and locking device is the same as in the first described form. The only difproper relationship of the ferences are with respect to the mounting of the operating lever D. In this form, the base plate of the locking device has a lateral extension or web 125. To mount the lever D a somewhatdifferent arrangement is provided. From the web 125 is outwardly extended a hub or journal 135 on which is freely rotatably mounted a special hanger or support 60, the latter having an upwardly projecting radial flange 61 and a shorter downwardly extending flange 62. Said hanger is held in place by a washer 140 and rivet 141. The lever D, at its upper end, has a loop section providing two side arms 63-63 which straddle the flange 61 and by which the lever is pivotally connected to the latter through a pivot-forming rivet 64. Below the pivot 64,

the loop is widened as indicated at 65-65 so as to surround the hanger 60 and alsoclear the washer 140. The lever is also suitably notched as indicated at 66 to receive the downwardly projecting flange 62 of the hanger so that, when the lever D is swung in a plane parallel to the car side, a substantial interlock is provided between the lever proper and its support or hanger.

In the embodiment just described, it is eviswingable about one axis for forcing the door open through the hasp or link'A and to close the door, the same as in the preceding form described. Similarly, the lever D is swingable outwardly so as to release the hasp from its staple, this movement being about the pivot 64, as clearly illustrated by the dotted line position of the parts in Fig. 6.

' door; and means I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
