CAR-DOOR FASTENER.

SPECIFICATION forming part of Letters Patent No. '781,7 56, dated February '7, 1905.

Application tiled April 25, 1904. Serial No. 204,791.

T (LU 71171/0721/ it muy cm1/cern:

Be it known that l, Jesse L. YARN ELL, a citizen ot' the United States, residing at Altoona, in the count)v of Blair and State ot' Pennsylvania, have invented new and useful Improvements in Car-Door Fasteners, of which the following is a specification.

My invention relates to improvements in car-door fasteners ot' that kind or st vle which is particularly adapted for attachment to slidable doors which when in closed position set Hush with the face of the car-body and which when opened slide over and stand parallel with the closed wall of the car-body.

The mechanism comprises a sliding' bolt, an actuating-lever, and means to hold the lever in locked position.

'lhe invention consists in the novel construction of parts and their aggroupment in operative novel combinations, as will be t'ullvY hereinafter described and the asserted novelty particularly set forth and distinctly claimed.

I have fully and clearly illustrated the improvements in the annexed drawings to be taken as a part of this specification.

Reference being had to the drawings, Figure 1 is a side elevation of a portion of a car-body shown as having my improvements attached. the Vfastening-lever being' indicated as locked in the fastening' position. Fig. 2 is a side ele vation showing the locking-lever as in the movement to carriY the door out ot' its seat in the car-body and placing the door so that it can be slid back on the trolleys. Fig. 3 is a vertical sectional view through the door and wall ot' the car and side elevation of the complete fastener. Fig. Llis a detail longitudinal section th rough the car-wall and the door. taken on the line i I of Fig. 2 and showing the fastener in plan view and indicating' the fastening-bolt as in locked position. Fig. 5 is adetail longitudinal section taken on the same line as that ot' Fig. 4 and showing the fastener as unlocked and the doer as partly swung outward to be moved to open the opening' in the car.

ln the drawings the same parts appearing in diii'erent illustrations are designated bythe same reference-notations.

Referring to the drawings, A designates a car-body, which may be of any of the usual and approved constructions adapted for the transportation of freight. In the side of the car-body is made an entrance, as usual, which is closed by a door l titted therein. The entrance has a top cross-piece 2 firmly secured to the inner face of the top rail thereof` and to the vertical side boards on the inside are secured cleats 3 l to bring thedoor-face flush with the outer face of [he car-wall. 'l'he cleats 3 I are formed with inwardI v-extendcd flanges 5, against which the door lodges when closed, and in the cleat 3 is formed a groove l5 to take in the flange made onthe stile of the door and lock it Jfast at that end.

l designates the door made up of vertical boards, as shown. which are secured lo top and bottom rails and vertical side boards. which pieces constitute the frame olthe door and bring its outer tace flush with the outer face ot' the car-body, as indicated in the drawings. 'l`he vertical stud or board T ot' the door-frame is formed with a tongue S, which engages in the groove 6 in the cleat 3 to hold the door fast by the engagement. Instead ot' the groove and flange the cleat 3 may have sockets made in it and the door be provided with studs to enter the sockets and hold' the door in position at that end. At a proper place on the car-body face is secured a bracket 9, on which the lower edge ot' the door rides while being opened.

Adjacent to the upper end of the :ar-facing are secured a pluralit)Y of brackets l0, to the outer ends ot' which is secured a horizontal rail il, on which the hangers ride. The main portion et' this rail ll lies parallel with the` face of the car at such distance therefrom as to permit the free movement of the door when being opened and closed. The end portion 1Q ot' the rail ll is inclined inward toward the face of the car, so that the hanger occupying that portion of the rail when the door is being operated will draw the door outward and when being closed the hanger will push the door into the desired position. 'lo the upper end of the door adjacent to the flanged side is secured a hanger 13, having a passage lil, in which the rail 1l is arranged, and in the hanger above the passage is journaled a roller l5, (see IOO the dotted lines,) which traverses the rail and rides thereon to support the door.

16 designates a hanger having a passage therethrough to receive the rail 11, on which the hanger rides, as indicated. This hanger 16 is provided with a roller 15, a duplicate of that arranged in the hanger 13.

Both hangers have their inner walls cut out, as indicated in Fig. 3, to afford for the passage of the hangers over the bracket-arms 10. The hanger 16 is formed at its base with an inwardly-extending part 17, which is provided with a vertical bearing-aperture to take in the upper end of the crank-shaft hereinafter described.

To the face of the door are secured upper and lower strap-keepers 17, constituting bearings for the verticalcr ank-shaft 18. The upper keeper being located in alinement with the upper edge of the door, as shown, serves as y a support for the crank-shaft, the crank 19 of which rests on the keeper and is formed with a vertically extending 'stud or projection, which engages loosely in the bearingaperture of the inwardly-extending part 17 of the hanger 16, substantially as shown. The lower portion of the shaft 18 is extended to form a lever 20, which is locked to a staple or eye 21, fixed in the face of the door. A fastening-pin 22 is one of the means which may be used to secure the lever to the staple. The lever 2O is formed with a longitudinal slot 23, for the purpose hereinafter specilied. 1n the cleat of the door-frame is made a horizontal passage 24, wherein is slidingly disposed a locking-bolt 25, which engages in a bolt-socket 26, made in the cheek of the vertical upright of the door-entrance, as seen in Fig. 4 of the drawings. To the end of the bolt is pivotally connected the one end of an actuating-lever 27, fulcrumed to a support 28, secured to the face of the car-door, as shown in the drawings. To the outer` end of the lever 27 is pivotally connect-ed one end of a link 29, the other end being provided with a stud 30, which slidingly engages in the slot 23 of the operating-lever 20. lt will now be readily perceived that when the bolt is shoved home into the socket in the frame of the door-opening' the bolt will remain locked as long' as the lever remains in the position seen in Fig. 4 of the drawings. ll'yhen the purpose is to open the door, the lever is released from its holding appliances and is turned outward and away from the door on a horizontal plane and the bolt is withdrawn by the movement an d at the same time the rotation of the crankshaft will lift the door from its seat in the opening', so as to escape the car-facing, and then by applying force the door may be run out on the rail 11 until the desired position is reached. A buffer or stop-block 31 is secured to the face of the car, which limits the movement of the car-door in that direction. W'hen the bolt is in locked position, a pin may be utilized to fasten it in position and the usual seal be secured in addition as a protective element. After the door has been opened and it is desired or required to return it to the closed position the lever is permitted to remain in the position assumed when in the unlocked condition and the door is pushed back until the door reaches the opening and substantially alines therewith, when the lever 2() is reversed from the unlocked position to the locked position, which movement turns the crank-shaft and pushes the door into the entrance and at the same time results in moving the bolt into locked position. It will be seen that the operating-lever lies in the locked position as well as in the unlocked position close against the door, so as to be out of the way of passing' cars.

' Having thus described my invention\ what 1 claim is 1. In combination with a car provided with an entrance, a door adapted to tit within the entrance, means for supporting the door, a crank-shaft to withdraw the door from the entrance, said crank-sh aft being' provided with a slotted lever, a bolt adapted to retain the door within the entrance, a lever fulcrumed upon the door and having one end connected to said bolt, and a link connected to the free end of said lever and provided with a stud arranged in said slot.
