MATTHEW J. FLANNERY, or MATTEsoN. ILLINOIS.

MEANS FOR OIERATING ANDiLOCKINGr SLTDING DOORS.

To all whomtt may. concern: Be it known that I, MATTHEW J. FLAN- NERY, a citizen of the .United States, residing at Matteson, in the county of Cook and State of Illinois, have invented a new and usefullmprovement inMeans for Operating and Looking Sliding Doors,- of which the following is a specification.

I have devised my improvements for-use more particularly in connection doors, though certain features be utilized in fasteni use in other situations.

thereof may In freight cars, especially, the doors, when freely movable to closed position,-are apt to shift back and forth in their .guides and strike the door-jambs when not looked, as in the case of empty'cars, with the result of impairing their parts. Furthermore when the doors are so constructed that they will jam tight and prevent shifting when the cars are jerked or suddenly stopped, they must be pried open and this often results in mutilating the edges of the doors or the door-j a-mbs, and this'necessity of pry-. ing'open the doors often occurs evenwhen they are fitted to the'guides to be moved freely therein. r

My objects, generally stated, are to .pro; vide an improved form of fastening means, of the automatically locking type, which shall be simple, durable and economical of construction; and to provide for use on freight cars or other structures wherein the movable parts are apt to require the application of relatively great force to initially separate them,-means preferably cooperating withfastening means for the doors, for initially forcing open the closure, as for example, the doors of freight cars.

'Referring to the accompanying drawings, Figure l is a broken face view of a freight car showing a part of the. door thereof equipped with my 'improved fastening and door shifting means, the door being shown in closed position and fastened in place by said means. Fig. 2 is an enlarged section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow. Fig. 3 is a similar view taken at the line 3 on Fig. 1 and viewed in the direction of the arrow. Fig. 4 is a section taken at the line 4 on- Fig. l and viewed in the direction of the arrow, the catch of the fastening means being shown by dotted lines in released position. Fig. 5 is a face view Specification of Letters Patent.

with sliding ng means intended for the door-jamb and of a modification of the structure shown in the preceding figures, designed, more especially, for barn dcors and the like; and Fig. 6 is a s'ection'taken at the line 6 on Fig. 5 and viewed in the direction of the arrow.

Patented Aug. 24, 19115. Application filed March 17, 1915. Serial No. 14,969.

. Referring more particularly to Figs. 1 to 4 inclusive, the keeper of the fastening means is represented at 7, this keeper being shaped as shown, to conform to with one of the side-rails 8 of the door-jamb of the car, and the adjacent body portion of the car, the keeper'being provided with aper tures 9, to receive'bolts 10 for rigidly securing thekeeper inp'osition. The shouldered portion 11 of the vkeeper,'which -is'adapted to cooperate with the catch device hereinafter referred to, extends inwardlv beyond the side-rail 8, and is united with a plate section '12 which extends in *an upwardly 1nclined direction rearwardly from the shoulder 11, this plate being provided with two apertures 13 and 14:, for a purpose hereinafter explained.

The catch-portion of the device which is carried by'the door 15, is represented at 16 and comprises a 'base member'17 and the catch proper 18.- The member 17, which is in the form of a hollow frame, as shown, is adapted to be secured to the outer face of the door as by screws 19, passing through holes'in this member, the forward edge of the member 17 being provided with a rearwardly extending lip 20 which sets into a recess 21 in the front side of the door 15 at the edge thereof adjacent to the rail 8. The member 17 is formed with a cross-piece 22 so disposed as to extend in spaced relation to the bottom portion of the member 17 as shown, and preferably beveled at its rear side, as indicated at 23, this cross-piece cooperating with the catch proper 18 as hereinafter described. Thecatch 18 is in the form of a plate provided in its outer face intermediate its ends witha groove 24; extending transversely thereof, the cross-piece 22 when the catch 18 is assembled with the portion 25 adapted to interlock with the shouldered portion 11 of the keeper, and extending rearwardly and upwardly in, an inclined direction from the shoulder 25, is a plate section 26 provided with openings 27 i and adapted to register with the opens ings 13 and 14, respectively, inthe plate sec tion 1.2 when the catch 18 is interlocked with the keeper 7 (Fig. 4). The other end of, thecatch member 18 cooperates with a'coile'd spring 29 interposed between the base of the member 7 andthe rear side of this end of the catch, this spring operatingto turn the catch member 18 on the cross-piece 22, as a pivot,"in a directionfor forcing 'rearwardly the shouldered portion 25iof'the catch, whereby when the door 15is moved to closed position the shoulder 25 will ride over the shoulder portion 11 ofthe keeper and snap into interlocking engagement therewith as represented in Fig.

In the construction nowbeing described,

the catch 18 is withdrawn from engagement with the keeper 7 to permit the door 15 to be opened, by means of a finger 3O projecting laterally from a shaft 31 journaled in bearings 32 securedto the outer face of the door as by bolts 33 and'providedwith an operating'handle'34, the finger 30 cooperat ing with the inclined rear edge 35 of a man ivardly extending lug 36 provided on the catch 18, theseparts'being so constructed and arranged, as shown, as to cause the catch1'8 to be raised to the position indicated in dotted lines in Fig. 4 for disengaging with theikeeper 7, when the shaft 31- is rotated, through the medium of the handle I 34, in a clockwise direction, in Fig. 2.

' Cotiperating with the fastening device and its'operating means, just described, are means for initially forcing the door 15 to open position upon the act of disengaging the catch 18 from the keeper 7, these means comprising a member 37 bolted or otherwise secured to the face of the rail 8 as indicated at 38 and provided with a laterally extendthe door 15 to the right in Figs. 1 to 4 in clusive, it being readily understood from the foregoing that, assuming the parts to be in the position illustrated in Figs l to 4 inclusive, the operator by grasping the handle 34 and swinging it outwardly, to rotate the shaft 31 in a clockwise direction in Fig. 2, first causes .the catch18 to disengage from the keeper 7 and then force the door 15 to the right in said figures, so that the door is unlocked and initially opened by practically one act on the part of the "operator,'-namely the'swinging of the handle 34 outwardly,

handle also serving as a means whereby the door may be pushed or pulled to fully 7 open position.

permit of theapplication of a seal to the fastening device for the usual purposes; and if desired, the handle 34 may be sealed in .position, "as by providing it with a slot 42, which registers with a slot 43 on an extension 44 provided on the member 37 and olfset relative to the door-j amb 8, in whichreg istering slots a seal may be fastened.

'Itwill furthermore be understood that p The registering openings 12, 14, 27 and 28.

when the shaft 31 :is rotated. back to the'por sition'represented in ig. 1 after the door has been opened, the catch device18 under the action of'the spring 29 is .tilted rearwardly at its shouldered end 25 and thus position the catchwill automatically interlock with the keeper7.

The securing means illustratedin Figs. 5 and 6 aresubstantially ofthe'same conwhen-the door 15is again moved to closed struction asithose illustrated in the preced} ingfigures- The keeper of this construction, representedat 45,is provided with a shoul dered portion 46 and'plate section. 47 'COI'i responding in general to the shouldered pore tion 11 and the plate section 12,0fthe pre cedingjfigures excepting that the plate 47' instead of-containing twoopenings contains a single open1ng48. In barn structures the doorjambs are not as a rule forwardly off:

set from'the wallof the barn, and Ihave, ,1

therefore, shown thekeeper 45 as having-a base which is flat instead of angle-shaped as represented of the keeper 7, which adapts it to be secured in proper positionagainst the wall 49 of. a barn adjacent to the door opening thereof; The members of the catch portion of the fastening means represented at 50and 51' and which are securedto the. 7

door 49*, are of substantially the same construction as the member 17 and catch "meme i 1 ber18 respectively of the preceding figures, thelshouldered portion 52 of the member 51Yand-the'p1ate section 53 thereof being similar to theshouldered portion 25 and the plate section 26 respectively" of the catch member 18, exceptingthat a single opening 54 isprovi'ded in the plate'member 53,: which registers with the opening 48Jwhen the fas tenin'g means'are in securing position, and furnishes a means for attaching apadlock, or the like, thereto Inthls construction meansi-are employed for permitting the catch 51 to be withdrawn from engagement with the keeper .45, from the side of the door opposite that to which the fastening means i are secured,these means in a desirable form comprising a chain 55 connected atone end with the end of the'catch member 51 adjacent its actuating spring and extending through an opening 56 in the the catch device is secured.-

doorto which What I claim as new and desire to secure by Letters Patent is:

1. An element of fastening mechanism for cooperation with a keeper, comprising a hollow member adapted to be secured in position on one of two parts to be fastened together, and having a cross-bar formed integral therewith, a catch device bearing intermediate its ends at its outer face against the inner side of said bar and adapted to rock on the latter, and a spring engaging one end of said catch.

2. An element of fastening mechanism for cooperation with a keeper comprising a hollow member adapted to be secured in position on one of two parts to be fastened together and having a cross-bar formed integral therewith, a catch device containing a groove in its outer face intermediate its ends into which said cross-bar extends adapting said catch to rock thereon, and a spring engaging one end of said catch.

3. The combination with members relatively movable toward and away from each other, of fastening means therefor comprising a keeper on one of said members, a catch on the other of said members interlocking with said keeper when said members are in a certain position, a rotatable shaft, means connected with said shaft, and separate from said catch for releasing the latter from said keeper upon actuating said shaft, means on said shaft for forcing said members apart following the disengagement of saidcatch from said keeper, and means for rotating said shaft. I

4. The combination with, members relatively movable toward and away from each other, of fastening means therefor comprising a keeper on one of said members, a catch Copies 01' this patent may be obtained [for on the other of said members constructed and arranged to automatically interlock with said keeper when said members are relatively moved toward each other into a certain position, a rotatable shaft, means separate from said catch, operated by said shaft when rotated for releasing said catch from said keeper, means operated by said shaft for forcing said members apart, and means for rotating said shaft.

5. The combination with a sliding door and its casing, of means for forcing said door to initially open condition comprising a cam on the casing, a shaft rotatably mounted on the door and having a laterallyextending handle section, and a finger on said shaft adapted to move against said cam when said shaft is rotated and force the door open,'the parts being so arranged that the handle, by which the door is forced open as stated, affords a means forpullingthe door to fully open position by continuing, in the same direction against the handle, the pressure applied against it to cause said cam and finger to cooperate as stated.
