CAR-DOOR.

Application filed June 14, '1909. Serial No. 502.01.

To all whom 'it may concern:

lle it known that l. Jost-:rn liianor., a

citizen of. the United States, residing at llouston. in the county ot' Harris and State of Texas, have invented a new and useful improvement in (lar-Doots7 of which the following is a speeitication.

M v invention relates to new and useful i improveinent'n inear doors and more particularly to means for supporting and fasletting' the door in place.

'Vl'he object of the invention to provide means whereby the door may be. fastened ttush with the outer surface of the ear or moved to various positions and fastened in plat' for the purpose of either closing the doorwaj,- or leavintc; tho Same partiall)1 open whereby ventilation is obtained.

Another object is the arrangement and construction whereby one vertical side of the door may he swung outward,.while the other is projected into the doorway; the door thus standing' atA an angle to the Side of the car and act ing as a delleetor to divert the air into the ea as the same moves.

Among other fiatures, are a guard strip i Speccation of Letters aent.

on the line f under which the edge of the door is engaged and prevented from being forced outward bj.' the load; fastening means associated with the lower ends` of the crank rods; and a gravity latch for fastening the crank arms when the door is closed.

Finally the object of the invention is to provide meansl of the character described that will he stroug.'durable, ellicient, and easy of operation, simple and eomparativel)r inexpensive to construct, and also in which the several parts will not be likel)v to get out of working order.

the invention has relation to certain novel of a freight car showing my invention applied thereto, th'c door being `shown closed iu full lines and open in dotted lines. Fig. is a transverse vertical section ol' the same. Fig. 2l is an elc\ation showing the door in position for ventilating the car. Fig. t is a horizontal ."ction of the same. Vig. I ia horizontal .section of the same with the position of the door reversed. l'ig. t3 is a near its upper and lower edges. 71th the above and other objects in view.

door swung parallel to the side of the car in front of the d \r-.vay, Fig. T is a detail in section of one of the tracks and the sliding hanger, Fig. fw' is a vertical section :a of Fig. l, and showing the gravity latch in position. and Fig. il a plan view ot the. crank arms.

In the drawings, the numeral l, desigi natcs the side of an ordinary weight. car and the usual door-way. Above and below the door-way, tracks 3 preferably of lian metal hats, extend longitudinally to one side. of the. doorway. v referring to Figs, 2

and T i'. will he noted that these tracks` are supported from the side of the car by sills lprcerahlv of wood, and suitably fastened to the car. The sills extend substantiallyY the. entire length of the metal bars, which project. ahove and below each sill. so that| the tracks each present a T-shape. in cross section. This consti-tuition is more desirable than T-irons or angle irons` as, it is less expensive, lighter and more durable.

lhe door-wav is rabbetcd so as to receive the door and hold the, outer face of the saine ,aiilzstanliallv tiusb with the side of theJ ear. Along one vertical side ot' the door way, lwhich we will call and refer to throughout this specification` as the lelt side. a vert ical guard .st rip tt is suitabl)v fastened So :Sto project' a .short distance over the door-nav or door opt-ning'. rl`ht`f left tnd of the door is adapted to engage nnder this ctrip and the door is thus braced against outward displacement.

i'he means for supporting and operating the door comprises Vertical ttanh rodS 'tpassing through boxes b' .secured to the door ()ne ot the crank rods` is placed near the right hand end of the door. while the other is positioned near the center. This' dispositit-tn of the crank rods in connection with the guard strip so thoroughlv braces the door. that outward displacement al'tcr the door hasl been hastened is practicall)l impossible.

il'hc upper and lower ends' of the rods A are ntl-,set or bent to form cranks which extend inward in line with the rods when the door i\ in its closed position. 'l`hese cranks project through hangers J provided with recesso ttl .n their inner fact-s of such shape as. tn receive the tracks Il and to be held against tran-weine displacement thereon, al

though permitang a free longitudinal slidhorizontal .se-tion of the san-.e with thel i ing :nm-ement there along. .\t their upper by pins 11; while the lower ends of the rods project below the lower hangers, at which point each is provided with a hole 12 adapted to receive a, key 13 suitably supported from the car, for the purpose hereinafter described.

Nearer the bottom of the door crank arms are secured to the crank rods 7. Each arm consists of a, collar 14C rigidly attached to its respective rod and having pivotal connection with a link 15, the links adapted to engage attheir outer ends a staple 16 projecting from the door and on which they are fastened, when the door is closed, by an eye-pin 1T suitably supported from the door. One of the links is oddset as indicated at 18 in Fig. 9, so as to lap over the end of the other .i k and permit the inner sides or" the links to rest substantially flat against the door.

Immediately above the collars 14, a. box 19 for each rod 7 is secured to the door. It is to be understood that the crank rods may be freely rotated in the

boxes

8 and 19, and by positioning the boxes 19 over the rigidly attached collars, the door is substantially supported thereon, thus relieving the lower crank rod boxes 8, from the friction which would result if the door was supported thereby.

It is to be understood that in order to open the door or move the latter out of the doorway, it is necessary to rotate the crank rods 7 which is accomplished by swinging the crank arms outward after the eyepin 1T has been withdrawn from the staple 16. It is necessary to swing the arms outward` a short distance, swinging the right hand crank a little farther than the left so as to draw the right hand end ot' the door out of the door way and also move the door a suilicient distance to the right to disengage its left hand end from under the uard stri 6, before the door can be fully opene After the door has been swung to its ontward position, it may be slid along the track to the right as indicated in dotted lines in Fig. 1.

One of the features of this invention is the arrangement whereby the door may be swung for Ventilating purposes, to ositions intermediate of the full closed an opened positions thereof. By referring to Figs. 3 and it, it will he seen that by giving the right hand crank rod substantially a half rotation and the left crank rod Substantially a quarter rotation, the righthand end of the door will be projected beyond the side of the car, while the left hand end remains in the door way a short distance from the guard strip; the door thus standing at an angle and acting as a detlector to catch the air and divert it into the car through the door way, provided the car is traveling to the right. If

, l l i the car should be traveling to the left the position of the door is reversed and is aocomplished by swinging both cranks a half revolution and then swinging the right hand crank back until the right hand end of the door is carried into the door way, as shown in F ig. 5. lVhere the cranks are each given a halt' revolution the door is caused to stand in front of the door way and parallel with the side of the car as shown in Fig. 6, thus admitting air to the car either way the same travels. It will be noted that in any of these positions the door way of the ear is not exposed and the door is substantially closed so far as entrance by persons is concerned. It is apparent that very little good would be sustained in moving the door into any one of the three positions just referred to if some' means for holding the door in these positions were not provided and one of the essential features of this invention resides in the means for fastening the door in position. In carrying out this part of my invention, I provide hasps Q0 of the half twist style, each stapled to the side of the car at one end and apertured and adapted to tit over the lower projecting end ofthe adjacent crank rod at its free end, lyinOp tlat against the under side of the lower hanger and being held in `engagement by the insertion of the key 13 in the hole 1'2. The hasps are so positioned, especially the right hand one, as to be swung either to the right or left and engage the crank rod. When the door is closed both hasps are engaged with the crank rods as shown iu Fig. 1. It is obvious that while the door is inthe door way, the crank rods cannot be rotated unless the boxes are permitted to slide, which they cannotdo while the hasps are in engagement with the lower ends of the said rods. When the door is swung to its full o pen position,` as shown in dotted lines in Fig. l, the right hand hasp is swung to the right and engaged with the lower end of the left hand crank rod, as is also shown in dotted lines in Fig. 1, which holds the door in its open position and fastens it against sliding on the tracks.

lhen the door is in the osition shown in Figs. 3 and al. the left ham hasp is engaged with the `let't hand crank rod, the right ha ad hasp hanging free as it is necessary toslide the door a little to the right to effect the flistening thus sliding the right hand crank out of register with its hasp. "hen the door is moved to the position shown in Eig. 5, the right hand hasp is engaged with the lower end of the right hand crank rod, and when the door is in the position shown in Fig. 6 both hasps may he engaged with the crank rods. Although sonic movement of the parts is possible when the hasps :ire in engagement willi the crank rods, the door is substantially fastened or held in position.

As an additional means for fastening the crank arms when the door is locked, in case l its closed the staple and eye-pin should become inoperative, I provide a gravity latch as shown m detail 1n Fig. S. This latch consists of a short. vertical track 21 similar to the track 3 and placed above the horizontal position of the crank arms. A latch memher ismouuted to slideon this track and is slotted so as to i engage ahout a holt 'lf3 driven into the track and which holt acts as a stop to limit the latch mem. r. 'hen released the latch member will slide down the track and deupward and downward movement of theil pend therefrom in front of the right hand link l5 which .laps over the left. hand link,

thus preventing the links from being swung i outward. upward and out of the path ot' the crank arms `when it is desired to open the door.

hy pivoting the links l5 to the collars lt. the former will swing down against the crank rods when released, thus obviatincr an obstructive projection when the door is opened. I also desire to he noted thatthe hangers 9' engage around the tracks 3 at their upper and lower edges and therefore should the car sag, Ithe hangers cannot become disengaged with the tracks as is oftenv the case with hangers which only engage one edge of the track.

What I claim, is:
