To all whom it may concern:

' Be it known? that I, DE WITT C. EDMOND States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented new and useful Improvements in Freight-Car Doors and Hangers; and I do declare the'following .to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figu-re's of reference marked thereon, which form a part of this specification.

This invention relates to railway freight cars, of the type fhatis known as box cars, the invention having reference particularly to the doors and the hangers thereof.

Objects of the invention are to provide improved car doors and hangers that may be relied upon to operate freely; to provide hangers which shall prevent loss of doors in transit and which willnot be liable to fracture in the severe service incident to the movement of cars, and to provide hangers that will beadapted to be made mainly of Y. larly described wrought or rolled iron, to the end that economy lIlCOl'lSbI'llClJlOIl and maintenance of car ,doors may be attained inthe highest degree.

- With the above-mentioned and minor objects in view, the invention consists in a car provided with doors of improved construction with reference to the supporting and guiding parts thereof,- a door having improved locking and latching devices, and improved and novel supports and guides for the doors; the invention consisting further in the novel parts and in the combinations and ar rangements-of parts, as hereinafter particuandreferred to in the appended clainis- Referring to. the drawings, Figure 1 is a fragmentary side elevationof a box-car body hav1n a t1"l1t,(l()01 and a ventllatin door '5 l h --mounted thereon in'open positions, all constructed-substantially in conformity to the invention;-Fig. 2, a fragmentary sideelevation of the car body equipped with the hang ers and attachments modified for a single door, the latter being omitted from the view; Fig; 3, an inside elevation of the tight door detached frOmthe car Fig. 4, a side elevation of one of the improved'do'or stops; Fig. 5, atraiisverse sectional view of the door stop taken approximately-at the middle portion thereof; F' ofthe fastening eyes of the doors; Fig. 7, a fragmentary verticalsectional View on the 1g! 6,8. perspectivcvicw of one line A-A in Fig' 1; horizontal sectional view on the line B-B in Fig. 1; Fig. 9, a fragmentary vertical sectional view on the line C- C in F ig. 1; Fig.

10, a fragmentary vvertical sectional view showing the lower part of the door and shoe the car body; b, the siding; c, the car floor;

(1, the roof; and e and f, the door-posts at opposite sides of a door way of the car, all, of ordinary construction.

In the practical embodiment, the invention includes a lower door rail F which is composed of rolled metal and suitably se cured against the siding b opposite to the side silla, the rail being so formed as to have an inclined guide side g adjacent to the siding, a narrow top h, and an outer inclined guide side 0'. extending downwardly from the top h, so that in the cross-section of the rail it resembles'that of the frustum of a cone.

The top ft of the rail has a suitable number ofv aperturesj therein in which rollers G are arranged and mounted on axles It that are supported'by the inclined guide sides g and i, the rollers being nearly incased in the hollow rail with the tops of the rollers slightly above the tops 71 of the rail. The side '2 of the rail has a suitable number of apertures Z therein to receive lock-bolts of the doors.

An upper guide rail H of novel form is provided and composed of rolled metal, and it is suitably secured somewhat below the edge of the roof (Z to the side of the car body, the rail being so formed as to have an inclined guide lip m extending downwardly, and in some cases a guide-platen having a guide rib p is interposech'as shown, between the siding b and the rail.

Fig. 8, a fragmentary The lip m of thefrail H has suitable loclebolt' keepers g secured thereto to receive lock bolts ofthe'doorsfl Therails F. and H are usuallyof suitable I length to extend'across the doorway'an'd beyond in both directions, so as to accoinnio date two doors as shown in Fig.1, a tight and t that are formed door I and a ventilating door J, one at either side of the open doorway, so that either door may be moved for closing the doorway. The framing of the doors may be variously constructed, and each doorhas a grooved botti'uninwhichis a metal shoe Kformed of rolled metal and bent over so as to form an outer guide lip K of the metal doubled adapted to extend over the side i of thelower rail while the shoe bears on the rollers ,G.' The shoe has also an inner guide lip 1* formed of. the 'metal doubled upon itself and adapted to extend over the guide side 9 of the rail F. Also the shoe is provided with a pair of flanges s of the bent up metal and embrace the lower inner and outer sides of the door to which they are secured for attaching the shoe to the .door. A suitable number of lock-bolt guides at are attached to the flange t, and there are apertures Z in the lip K serving as keepers for the bolts.

The top of each door is beveled and is provided with a face-plate L that fits and is secured to the beveled ed e of the door and has a flange v extending alon the rear sideof the door, so as to engage t e rib 1) while the beveled faced front of the door engages the lip m of the rail'H. A suitable number of lock-bolt guides w are attachedto the face plate L. I s

In order to efl'ectually retain the car doors on the lower rail and to prevent movement of the doors beyond the ends of the rails to cause them' to become lost in transit, a pair of substantial sto s M and N are provided and secured in a irm manner to the side of the car body at the ends of the door rails, the

stops being alike but applied to the car in reverse order, each stop being composed of a wrought bar and having a suitable numberof guide fingers O and also av guide finger P secured thereto, the finger 1? having an eye :1; attached thereto, for assisting in holding the door open when the car may be in motion.

At the middle of each door I and J a base plate Q is secured to the outer side thereof, a disk R is pivoted to the plate, andtwo loekbolts S and S are pivoted to the disk and extendthrough the guides to and w respectively, the lock-bolt S being projectable through the aperturesl and' Z, and the lockbolt S being projectable through the keepers g, for locking the door in different positions, either closed, partially closed, or open. lever T is secured rigidly to thedisk R and has a-handle U pivoted thereto that has an opening 2 in its end, there being an eye y attached to the car body below the plate Q to which the handle may be locked or sealed, the eye having a holdin plate 15, as in Fig. 6.

The door J is provided with a hook V at an end thereof to engage the eyes; of the linger P that is part of the stop M, and the opposite end of the door has an eye y attached thereto that may be c'ngaged by a hook W A comprising a concavo-convex which is connected to the door I, so that the two doors may be cou led together. The door I has. also a hook connected thereto for engagment with the eye a; of the finger I that is part of the stop N.

When a side of a car is to door, the stop M is placed adjacent to the door post a, as in Fig. 2. Itwillbe observed that the door stops. extend from the 'rail F to the rail H so that a considerable number of bolts or screws maybe used to firmly attach the stops to the car body in order that the stops may not become loose, the rails and the stops forming together a frame in which-the door or doors are securely confined. The doors are provided with handles Y.

' In practical use, the doors will inov,e easily on the rollers and should be hooked'to the stops when open, and con led together when either door is closed, an

also be locked by means of the lock-bolts in any position.

The advantageous results attained by the above-described. construction will be fully understood as being obvious from the deto say that cost charges for lost doors may be avoided by the use of the invention.-

Having thus described the invention, is claimed as new is.
