This invention relates I to improvements .in sliding door operator, and more particular- 1y sliding door operators adapted for house cars, and this application is a division of my pending application, Serial No. 722,761, for Improvement in doors,'filedJune 27,1924;

Qne object of this inventionisto provide simple and effective operating mechanisms for slidable doors, and m orel especially slidable doors of the outside type for box cars and automobile cars, wherein a powerful initial opening movement and a powerful final movement may be imparted-to the doors. i T

-Morespe'cifically, anobject of my invention is to provide a door operating mechanism for the purpose indicated,"which comprises an operating lever of the second class and a cooperable detachable link so arranged that the lever andlinl: may be' disconnected after the initial opening movement'has been 1mparted tothe door.

other objects of the invention Will more "clearly appear from the description and claims hereinafter following.

In the drawing, forming apart of this specification, Figure 1 is a broken side elevational view of aportion of a box car, snowing my improvements inwconnection therewith. I And Figure?! is abroken horizontal sectional view, iiponan enlarged scale, corresponding to the line 22 of Figure 1.

In said drawing, the side wall of the cari is indicated at 10, the same having a'single door openin 11 provided therein, said door opening being defined in part, by vertical wood posts 12 and 13 which are preferably sheathed to protect the same by metal plates I My improvements have been illustrated in connection with a slidable door of the alli'netal type, said door being indicated generally by the reference character A and, as

' shown, comprises three sheet metal panels 15,

16 and 17, each of the panels having a central,flat, dished portion and provided around the margins thereof with an outwardly ex tending, inclined section 18 and a flat flange 19. The fiat flanges 19 on the meeting adjacent edges of the, panels are overlapped and in Figure 2, andan riveted, as indicated at 2020, thereby providing what maybe termed two horizontally I extending corrugations within the area of the door. Around the otheredge portions ofthe' panels suitable rolled sections are preferably secured thereto, aJZ-bar21 being nsed' along the front edge of the door, as best indicated angle .22 along. the vertical rear edge. v i I p Bridging strips 23 23 are also preferably employed, each strip being riveted to themain portions of thepanel sheets inwardly ofthe offset sections and to the rolled edge elements, as will .be understood. front edge construction shown. a-double-ply, fiat, marginal. portion is provided, as indicated at 24, the same being adapted to enter a suitable recess provided between the front post '1'2'and the outer flange of a Z-bar front stop 26. The rear edge angle 22 is With the preferably provided with a forwardly turned flange 27 at'its inner end, the same'being adapted to beseated behind a flange of an angle Weather-sealing strip 28. As will be understood, my improved door operator -.is

not limitedto any particular typerof door,

the one shown anddescribed being for purposes of illustration only.

My lmproved door operatr comprises,

broadly, an '0]:)erating lever B, mounted on a bracket C, and a link D mounted on a bracket memberfto which it is applied. In the instance shown, said bracket. C is of more or less right angular form, having a flange section 29 riveted. to the web of the door stop 26, and a flange section 30 spaced outwardly tromthc door stop andapproximatelv in a plane coinciding with a plane passing through the crest of the ofi'set portions or the door. The bracket C is suitably reinforced by ribs 31, and the section. 30 is provided with an outstanding pivot stud or boss 32, on which is p votally mounted the lever 13, the latter being held in place by any suitfablefmeans, such as the washer 33 and rivet The operatinglever Bis pivotally mounted atxitsupper end on the stud 32, as above described, and is provided at its lower end witha hand-holdorigrip section 'lntere mediate its ends, the lever B is provided with a preferably integral stud 36 extended outwardly from the car side, said stud hav ing a slightly enlarged annular flange 37 at its ou'terend, for the purpose hereinaftendef scribed.

applied. In E'has a bottom flange 38'riveted to the fiat dished portion of theylower' anellT- an" u u l i I outwardly inehnedsection 89 tittin 'against. the inclined section'l8 of the panel sheet;

and an outer mainhub section d0, the latter being provided'with a stud 41 on which is loosely plvotally" mounted the link D. The stud L1 is preferably of greater length than the width of the link D so that the latter may not only swing on the stud ll in a plane parallel to the plane of the door, but may also be swun laterall .withres )ectto the r doom for the purposehereinatter described.

The link D is preferably held in assembled relation with the'bracket Ev any suitable means, such as the Washer 42 and rivet 43.

The link D, at its free end, is provided with an opening 44 just large enough to pass over the flanged end 37 of the stud 36, so that it may be received'on the stud proper 36, and when in operative position will be partially overlapped by the flange 37 so as to prevent accidental disengagement, laterally, o-t the link. I

In the drawin the operative interconnected condition or the lever B and link D is shown in full lines, with the parts 'in such position as to start the opening movement or" the door. This is accomplished by the operator swinging the lever B in acounter-clockwise directioinit being observed that the means;

through in effecting the final closing movements of 'the doon as will be obvious.

' As will be appreciatedfrom the preceding description, the dooroperator consists of a minimum number of parts and so arranged as to most effectively apply the power to the door in either an opening or closing direction. Although I have illustrated the operator with the lever supported from a'fiXed part of the car 'andthe' li-nk attached to the movable .door, it'isfobvious that the arrangement of V these parts may be reversed and further that r 1: 4+ V lhennk at aching bracket Ewill be 0t any 7 suitable-desired formation adapting it to the particular configuration of door to WlllCll" the instance shown, the bracket the door operator may be made effective between the usual main and auxiliary doors of an automobile car, without departing from the spirit of the invention. I

"WhileI have herein shown and described what'l'consider the preferred manner of carrying out my invention,the sameis merely-illustrativeland I contemplate all'changes and modifications that come within the scope of theclaim appended hereto.

Iclaim; I

In a door operating mechanism, the combination with a horizontally slidable door member; of a second member toward andfrom whichthe door-member is'movable; an operating lever pivoted at its upper end to one of said members; alink pivotally attached at one'of its ends to the other of said members so as to swing in a vertical plane; and cooperable, detachable, interengaging means on the free end ofsaid' link and on said lever, the means'on'said lever being disposed at a point intermediate the. pivoted and freeends of the lever and so located that, when the door is in closed position and the link and lever are interengaged, the link is disposed substantially horizontallyand the actuating, force transmitted from the lever to the link in a direction to open the door, initially passes substantially horizontally lengthwise of the link. In witness that I claim the foregoing I have hereunto subscribed my name this 11th day of June, l928.

powertrom the lever B is applied to the link; V l) substantially in a horizontal line passing through the pivotal connection of thelink D V with the door, thus obtaining the most ethcient application of the power to the door and minimizing any tendency to cook or tilt the door While starting it. Then the door has been. shifted in an opening direction as far as desired and within the range of the door og z-erator. the link D then has its free end disa igcd iroin the stud 36, the balance of the opening inm'einent of the door being accomplished in any other suitable manner. When the link and lever are disengaged, it is obvious that each will hang in a dependent position, asshown by the dotted lines in Figure 1. The reverse procedure. vwill be gone
