SIDE-DOOR..OJE'ERA'IIN(ify AND HOLDING vIVCIEICHANISIMI.

Application l'ed December To all lwho/m. t may conce/m.' l

Be it known that I, .JOHN F. OCoNNoR, a citizen of the United States, residingfat Chicago, in the county of kCook and State of Illinois, have invented a certain new and useful Improvement in Side-Door Operating and Holding Mechanism, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

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

The object of this invention is to provide a simple and relatively inexpensive device which may be applied to a door of the sliding type, and which will have effective means for either` drawing the door tightly closed or starting the opening operation thereof, together with means for locking thedevice in a predetermined position to hold the door either `in fully closed or partly opened position.

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

In the drawing forming a part of this specification, Figure 1 is a side elevational view ycfa portion of a box car, showing a portion of the side door thereof with my improvements in connection therewith. Figure 2 is a horizontal, sectional view, corresponding substantially to the line 2-2 of Figure 1. And Figure 3 is a vertical, sectional view, corresponding substantially to theline 3-f3 of Figure 1.

In said drawing, designates a sliding door of a railway box car which may be either of the top or bottom hung type. One of the door posts is indicated at 11 in Figure 2, the post being provided with a door stop 12 against which the forward edge of the door is adapted to bear when the door is v fullyy closed. A portion of the side wall of the car is indicated at 13.

The improved door operating and locking device, as shown, comprises broadly, ,a stop bracket A; apivot plate B; a two-part head C; an operating lever D; a pull arm E; and a locking bracket F. l The pivot plate B, which is of circular outline, is provided on the outer side thereof with a central cylindrical boss 14 servingas pivot member for the two-'part head C. A p

t lpfextending axially through thegboss S, 1923. Serial No. 679,310. v

f 14 and the door serves to fix the plate to the door, a disc washer 16 being interposed between the head of the bolt and the outer end of the boss, for a purpose hereinafter described. Y

rlhe two-part head C comprises a pair of counter part discs 17--17.4 Each disc 17 is in the form of a circular latfplate having a radial enlargement at one side as indicated at 18.v The discs 17 are each provided with a central, pivot-receiving opening 19, the opening being surrounded at the inner side of the plate by an annular flange 20 forming ahub section. Each disc is also provided with a radially disposed, relatively wide rib N" 21 extending from the flange 20 ,to the pe,-` riphery ofthe disc, the rib corresponding in height to the flange 20. As clearly shown in Figures 1 and 3, the rib and the enlargement 18 vare disposed on opposite sides of the hub, but are not at diametrically opposite points, the rib being offset to one side thereof. Each rib is also provided with a transversely extending, semi-cylindrical recess, forming a half bearing 22. The two discs forming the head C are mounted on the pivot 14 with the respective lugs 18 and ribs 19 thereof in registrationl and the hub seotions 20 and the ribs 21 in abutment. When the partsare thus assembled, the half bearings are also registered and define a complete cylindrical bearing opening. v y

Thewasher 16, which is ofl larger diameter than the pivot member 14, serves to retain the two-part head on the pivot. To assure free rotation of the head,4 a slight clearance is provided `between the washerv 16 and the outer face ofthe two-part head C,'the outer end ofthe pivot member beinfr extended beyond the outer face of the hea as clearly shown in Figure 3. The hub sections 20 serve to space the plates 17'of the head C, provided an opening therebetween adapted to accommodate one endof the pull arm E.

The pull gated. flat plate having one end, pivoted between the plates 17, at the enlarged portions 18, by means of a pin 23 formed integral withl the innnermost plate and extending through the enlarged portion 18 of the other plate. The outer end of the pin is preferably yupset to prevent separation of the lates. At the outer or free end, the arm E is bent upwardly, as seeninl Figure 1, to

arm Eis in the form ofv an elonprovide a tapered! hook member 24;; The partsv are so' proportioned that when the Varm E is'horizontally disposed, as shown lil in Figure l, the lower edge of the same will bear'on the hub of the head C and a'stop .pin 25 disposed adjacent the periphery of the head. kThe pin 25/is preferably formed integral with the innermost plate 17 and extends through the other-plate, the outer end of the pin being` also upset to prevent separation of the head sections.`

The operatingflever D is in the form of an elongated barhaving a forked head'26'at one 'end thereof. Extending between the arms, adjacent the outer end of theforked head, is a transverse pivot pin 27, the same being preferably formed integral with the arms. The pivot pin! 27, which is journaled inA the" semi-cylindrical bearingseats 22,

' serves to 'support the lever for' limited swinging movement on the head C at right angles to the plane of the door. The head 26 has the front and rear faces' thereof tapered in opposite directions from the pivot" pin 27,- asclearly shown in Figure 3, to permit the lever to be swung awayl from the door to a vposition wher'e'it will be dis` engaged from the locking bracketF where itmay be conveniently operated and proper" clearance provided for the operators hand. At Vthe free end, the lever is preferably rounded off to tion 28.

lnassembling-the lever D, pull arnrE and head C, the'lever and pullarm are ifrs't applied to the inner section 17 which has the pins and 2li integral therewith,

by placing the pin 27 ofthe lever in thehalf bearing section 22 and `mounting the arm Eon'the pin 23. yThe outer plate 17 is then applied Yand the endsy of thepins 23 and 25 upset. After the parts have thus heen assembled, the pivot member 14k ofthe plate Tris passed through the opening 1li vof the head C and the washer 16 andthe bolt'l applied. The plate B is then fixed to the doorlO by theabol-t 15. To prevent accidental turning of theplate D with the head C when the latter is oscillated, a pair of dowel pins 29 are preferably provided on the` rear face of the plate B seated in suitable openings formed .in the door, the

sequence of operations takes4 place.

providea hand grip porrlhe bracketl?,l which is in the form of' a lock or car seal is adapted tov be engaged within the perforation ofthe lug'31 to lock the leverA to the bracket lF in a well known manner. Y Y n The stop bracket A is in the form of a flat plate lixedto the outer side of the door stop 12 by a plurality-of bolts 33, or Vother suitable securing means. A pair of outstanding, spaced,n downwardly j opening sockets 345-34 are provided at opposite ends of the lower side of the plate, the sockets being-'inwardly tapered and either of the sameheing adapted tovreceive the hookend ofthe arm E; The side wallsof the sockets 3a have alined slots therein as indicatedat 35 andthe end ofthe hook 24 is provided with an opening fadapted to be brought into a'linement with the slots to receive the iisualcar'seal.-v l f Assuming that the pantsarei in the posi# tion shown in full lines inthe drawing, when it igdesiredl to open the door, the followiplg T' e lead" seal and the lock associated respectively with 'the bracket ,Ai and the lng 31 are first' removed, after which the lever D is` swung outwardly to disengage it from the lug- 31. Thereuponthe lever is swung ina counter-clockwise direction, as seen 1n Figi ure l, to the dotted line position, rotating the head C therewith and through the medium of the pull arm E having-the hook thereof engaged in the outermost socket 34,' forcing' the door open to thev dotted' line position. When the doorhas be'enthns partly-opened, the hook portion of thefarm'E maybe -disenf gaged from the socket .andthe door fully opened by'l merely pushing the same in the usual manner. Upon-the operator releasing his grip from the leverA D, vthe latter will swing vdo-wnwardly under the infiuence of gravity to the lfull line position shown Vin Figure 1.-- n

When the'door is in openedv pull -arm` E will ordinarily be swung'v clockwise about its pivot 23 so as tohang in? a position, vthe.

lli?

depending position at the right hand of the operating-lever D, as viewedv in Figure .1, to

thereby eliminate danger of the pull arm vbeing broken or distorted'shonld it befleft projecting:beyond the freeedge-'of the door. i lf Lfor any' reason, `it is foundthat the door cannotbereadily' pushed openfwfh'enjit hasv been forced to the dotted line positionl shown, the hooked endof the armfE may be engaged within the innermostsocket and Y the described operation of forcing'the d-l'oor to the right repeated; tl'iereby obtaining-aalv greater door opening. In 'other words, the

hooked end of the bar may beY successiifely f engaged within the two sockets to force the Y door open.

then it isdesiredr to 'close thedoor, the

lattervismoved as near the stop-12gas can be conveniently'.- done by the'` operatief Without thel use of tools. The -handle D is then brought to the dotted line position shown in Figure l and the hook end, of the bar E engaged with one of the sockets 34, the same being shown as engaged with the outermost socket, as seen inFigure l. Assuming that the hooked end of the arm is engaged within the outermost socket, upon swinging theY handle downwardly to the full line position shown in Figure l, the door will be positively pulled to the fully closedpositicn. When this condition has been reached, the stop pin 25 will have been brought into abuttingrelation with the lower edge ot the arm E, thereby positively holding the hooked end of the bar in the socket. To lock the parts, the lever D is engaged, o-ver the lug 3l and the padlock or other locking device applied. The car seal may then be passed through the alined openings in the .sockets and hooked portion of the arm E. It will be evident that, as movement of the lever is prevented by thelugl and the pin 25 positively prevents rdisengagement of the hooked end of the arm E, the door cannot be opened by unauthorized persons without leaving visual vevidence thereof. Y It', for any reason, it is found that the door cannot be readilymanuallypushed enoughfto the lett as seen in Figure l, to engage thehook of the arm E with the outer socket,g-the same may be first engaged with the innermost socket and the door pulled to partly closed position by swinging the handle downwardly. In other words, the hooked end of the lever may be successively engaged with the two sockets to bring the door to fully closed position.

My improved door operating and. locking mechanism is also adapted to hold the doorl locked in partly opened position itor ventilating purposes. To thus lock the door, the same is brought to the dotted line position in- Figure l and the hook of the` arm E engaged within the innermost socket 34. lever D is then engaged over the lug 31 and the parts locked and sealed as hereinbefore described.

Although I have herein illustrated the i bracket A as secured to the door post, and

the lever mechanism together with the remaining associated parts as secured to the door, it will ,be evident. that the positions of the parts may be interchanged without departing from the spirit oi' the invention.

' 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 ot the claims appended hereto.
