'WILLIAM E. WINE, OF TOLEDO, OHIO@ :DOOR ARRANGEMENT 'O'R RAILWAY GARS.

Application iiled November 26, 1921. Serial-No. 517,920.

the doors in closed positions. Other ob 4 jects are to provide a self contained device which may be applied to the car as a single unit of manufacture and one in which there ushall be a minimum of weight andmaximum y of efficiency. `Also t0 eliminateA in door vlocking mechanisms the complex winding arrangements that are frequently used, and to which repairs are more frequently necessary than to the present character of device. With such objects in view,

the invention consists of the formation, combination and arrangement of parts as will be herein described, and particularly as pointed out in the appended claims.

In the, accompanying drawings, which show a preferred embodiment of the invenon the line 3 3 of Figure 1.

tion, Figure l is ai fragmentary side elevational view of a railway car having a door locking mechanismv constructed in accordance with the present invention.

l Figure 2 is a fragmentary transverse vertical sectional view through the same, taken approximately on the line 2 2 of Figure 1.

Figure 3 is a similar sectional view taken Fi re 4 is ay fragmentary diagrammatical view showing, to a considerab y reduced scale, the arrangement'ofsome of the doors upon a car.

Referring now to these drawings, the side of the car is indicated by the reference numeral1.' The numeral 2 denotes the bottom side angle -of the car,'which is secured to the side 1 of the car by means 'of rivets 3. The angle 2 is disposed slightly above the lower edge of the side plate 1 and the .of lading such as coal or the like.

outstanding leg 4 of this' angle is turned towardthe inside of the car and forms a ledgeV beneath whichrthe door may seat, thereby forming'a seal to prevent the rllrils e door itself may be formed of a single plate 5 with down-turned side` flanges such as 6.V

The' arrangement of vdoor and car side is such that, as before stated, the plate portion 5 of the door seats beneath the horizontal leg 4 of angle 2, while the down-turned flange 6 of the door plate lies parallel with and just slightly insideV of that portion of the car side 1 that extends below the angle 2. The door itself thus lies wholly within the lines of the car sides such as 1, and the dooi` may lbehingedeto the car floor by co-operating hinges 7 and 8, with hinge pintles 9. 'The doors, as shown in 'the drawings, swing parallel with the sides of the car andI nottransversely of the sides.

The preferred arrangement is that two setsof doors .shallj be arranged with their remote edges hinged and With the free or swinging edges adjacent to each other, there being preferably down standing flanges 10 formed on 'the adjacent edges of the doors so as to provide some depth tothe space between the free edges of the doors when the same are closed, thereby making it more -diliculu for material to lose out of this 'opening in transit.

or supporting the doors, a single supporting bracket 11 is secured tothe outer face of the car side 1,\some of the rivets 3 being utilized for the securing of this bracket, and there being additional rivets 12 provided for this same purpose, the same being located above the line of rivets 3. The bracket is formed with outstanding lugs or ears 13 arranged in pairs. These lugs arer all provi-ded with aligned holes through which is passed in a horizontal direction a pin 14. The pin is held in position by means of cotters 15 which. are located between the two central lugs 13, the cotters passing through suitable holes in the pin 14 and being so locatedas to prevent axialv movement of the pin in either direction. tween each of the pairs of lugs 13 is a door supporting hook 16. These hooks are each pierced at their upper extremities and are pivoted upon the pin 14 which passes through the holes inthe hooks. One hook is provided for-supporting each of the doors and' 'j' the hooks are arranged to, swing transversely of the sides of the car. The hooks are duplicates of each other, with a horizontal door supporting or locking face 17 located somewhat below the pivot point ofy each hook and 'in vsuch positions as to be swung beneathand slightly inside of the lines of the car side when the hooks are in position for supporting the doors.` Each door is provided with aln extension which may be formed by riveting a short length 18 of angle iron to the down-standing flange 6 of the door by means of the rivets 19. rIhe angle iron 18`th1'1s constitutes" a door-supporting -arm which extends outwardly beyond an edge of the door and beneath the down-turned marginal stiffening flange 6.

-way o VThe horizontal le of this angle is outstanding from -the e ge of the door and extends outward beneath the car side 1 and slightly outside of the lines of the car side.` Thelooking face 17 of the hook seats beneath the horizontal leg of this angle iron when the doors are closed.- Each hook has a suitably inclined approach facev 2O for ,causin the hook to swing back out of the the-extension 18 when the door is lifted. When the door is fully closed the weight of the hook will cause it to drop into positionbeneath the angle 18, thereby sup- 'jA porting the door and` reventing its release until the hook 16 isI orced out of engagement with the door extension.

In order to prevent the accidental withdrawal of the hooks and the consequent release of the doors, each hook is provided with a lof'cking cam 21. This-cam is set at an acute angle to the line of, the car side, so as to conform to the lines of the door hook and rotates at right anglesv to the direction vof swing of the hook.. The cam is made in thecustomary manner with a contacting surface 22 arranged .eccentric tothe axis of pivoting 23 lof the cam, which axis corresponds substantially with the center of the securing' pin or rivet 26. The cams are 'pivoted' .upon the brackets independently of 'any other fasteningsfthere eing trunnions.24 formed upon the brackets, these being of suitable form and 'size to rotatably accommodate the cams 21 and to form pintles therefor. Afterl the "cams are slipped over these pintles a washer such as 25 is .b-llaid upon the. top ofthe trunnon 24, and the rivet 26 is `driven through this washer and through a suitable hole in the center of the trunnion. The rivet 26 does -not pass through ,the lcar side 1, there being a suitable cavity 27 on'. theV inner face of the bracket 11 to receive the rivet head. Suita ble cam seats 28 are formed u on the backs of the hooks 16 against whic the eccentric faces 22 of the cams operate.;l y

It will thusbe seen that the pair of dooi` locks and cams, together with 4the attaching bracket, form a self-contained unit which may be manufactured and assembled and then taken to the car plant where the entire mechanism may be applied `-to the side of the car as a unit without necessitating any co-operative fitting or matching up of parts by the car'buyilder. The rivets 3 and 12 which 'are used for attaching the bracket 11 to the car side do not have any function in holding together the various parts of the locking mechanism, so that the car may be constructed in the ordinary manner and the entire mechanism .applied after having been correctly gau ed and fitted together in a separate ant, especially arranged for this more re ned class of work. This is a feature of construction bodiments are contemplated within the scope',

of the appended claims without departing from the spirit of the invention.
