Application filed August 2, 1822. Serial No. 518.296.

. To all whom it may concern:

Be it known that T, How um :M. VAN AIBTYNE, a citizen of the United States, and niesident of Renssrlner, in the county, of Rensselaer and Shite of New York, have inrented a new and Improved sliding Door easy of access, and combining ease and siinplicity of operation with mggedness and. strength of construction.

A further object residesin the provision of means whereby the door when moved to closed osition can be very easily locked in ever irection and will also be elllciently rein orced. i a

A still further object resides in the perticulnr construction and arrangement of'pefrts which are hereinufterxlescribed and claimed and-shown in the accompnnying drawings.

The invention is illustrated in 'thedrawlog, of which v 'gure l is aside elevationof the doors of, a. freight car shalt}; the door which carries the post in its cl position. v

Fig. 2 is a section taken on'theline2-2 of fiigfl is a. longitudinal vertical section taken through the lower end of the post construction. V

Fig. & is a section taken on the line 4-4 of Fig. 3.

The form of the invention shown in the drawings is a preferred form, although it is understood thatmodifications in the con-. struction and arrangement of the parts and in the character of the naterials used may be adopted without departing from the spirit of the invention. V

A referred form of the invention, as shown in the drawings, is applied toa sliding freight our door, and it involves themes of :1. steel channel member 1, preferably U- shnpe as shown in Fig. 4, one of'tho legs of which is bolted to the inside of the end of the car door 2. This channel beam or member 1 extends along the inner face of the door from the floor of the car to the top of the door and acts as a reinforcement or stiffening means for the floor, Over the lower and upper ends of this channel plrite or stillening member 1 I pass a U'shaped strap 3 providml with an aperture 4. 'lhs igs of this strep. 3 my be suitably. fastened, as by rivets 5, to the lower endof the reenforoing member 1.

, Associated with both the upper and lower ends of the stitfening'member 1 are a eir of post locking plunger-s such es 6. These .p l ngers ere actuated by links 7 connected to copper: sting arm pivoted at 9 to the 'stificning memher 1 or to the door 2. These .plnngers-or bolts 6 are so disposed that when the arm 8 is in the approximately horizontal osition shown in F1 1, the bolt $3 will be wi drawn from suite e openings formed between hhannel plates 10 and 11 whiehare disposed r ends of the stillemng member 1'. Eac "ofv these channel within the lower and up plates 10 and 11 are formed of U-sha ed plates the bases of which abut eaohot er and are provided with semi-circular curved grooves 12 which whenplnced in registration with each other form. a. circular passageway for the bolts 6. The ends of theseguide plates adjacent the ends of the stiffening member 1 are-disposedenssnitnble distance therefrom and from the strap 3 to provide a space into which a, tongue 13 mounted on a stop plate 14 can pro'ect; This to e 13 is disposed (bore the p ate 14 and is a opted to project ilbove and parallel thereto into the space formed between thochanneliplntes 10 and 11 and the strap 8 as shown in Fig. 3.

This tongue is provide with an aperture or here 15 through which the bolts 6 extend; The stop plate and tongue are fastened to the bottom of the car by any suitable means, such as bolts 16. The sto lets beneath the tongue 13 and the strap is provided with a recess 17 into which the'end of the bolt or plunger 6 extends. It is understood,

:of course, that this-lock construction, shown and described i l-Figs. 2, 3 and 4, 1n connection with the lower end of the stitlenin niember 1, is identical at the n par and o the stiffening member and that t o operafiinfi arm 8, when properly moved, will lock ends of the stiffening members simulta neously.

It 'will be noticed that when the door is pushed shut the reinforced ends of the post,

namely, thsstrap 3, surrounds the tongue 13 on the stop lates 14, and b this onngement lock t 0 door post in V9 directions, namely, up, down, away from the interior of the cair, toward the interior of the car, and in-the direction of the door morenot be overlooked and not moved to theloc-ked position.

What I claim is 1. A door construction which includes a slidable door, a, U-shaped channelmcmber disposed on the end'thereof and extending from the top to the bottom of the door, a

strap disposed across the ends ofthe U- shaped channel member, a stop member dis-' posed on the car adjacent each'end in the channel member, a tongue on said stop member projecting into the channel member between the end thereof and the strap, said tongue and the strap having apertures aligning when the door is engaged by the stop, and

means on the channel member adapted when ooerated'to project through said apertures to lock the door to the stop member.

, 2. A door construction which includes u slidable door, a U-shaped channel member fastened to the end thereof and extending from top to bottom of the door, one leg of the U-shaped member being fastened against the inner face of the door, the open end of the U extending fbrwardly in the direction of movement of the door when closing, a strap disposed across each end of the U- ,sbaped member and having an aperture therein, a stop plate disposed on the car at the bottom and top of the door a-ndha-ving a socket therein, a tongue onsaid stop platc projecting parallel thereto and spaced thereabove, said tongue hun ingan aperture therein and adapted to project-into the channel member between the end thereof and the strap to align the aperture in the tongue with that in the strap and the socket in the stop plate, slidable bolts disposed at the ends of the channel members, means for guiding the movement of said bolts, and

.means on the channel member operated at will to project said bolts outwardly-through V said apertures and into said socket to lock the door from movement inva plurality of,

directions.

3. A door const'ruction'which includes a slidnble door hnving an end portion, a reenforcin member fastened to said and 'portion and extending along its length, door stopping means fastened to the body of the l car adjacent the ends of the door, ands strap on the end of the r'eenforcing member to engage with the stop member, the engagement of the strap and stop members locking the; door in allbut onepossiblc direction of movement.

,4. A door construction which includes a slidable door havingan end portion, areenforcing member fastened to said end portion and extending along its length, stngmeans fastened to the body portion of lilo, car adjacent the ends of the door, a strap on the reenforcing member engaging with the stop member to lock the door in ."allbut one possible direction of movement, and manually operated means on the end of the door to be moved intoengagem'e'nt with the stop member to lock the door from move ment in this final direction.
