CAR-DOOR.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed October 13, 1906- Serial No. 338.803-

To all whom it may concern:

Be it known that we, JOHN L. SEVERNS and ILLIAM P. MoDERMoTT, citizens of the United States, residing at East St. Louis, in the county of St. Clair and State of Illinois, have invented new and useful Im rovements in Oar-Doors, of which the fol owing is a specification.

This invention relates to car doors more particularly designed for use on freight cars, but capable for use in other relations.

One of the objects of our invention is to provide a horizontally sliding door having an opening therein, and a vertically sliding closure for said opening.

Still another object is to providea laterally sliding door with an opening to be closed by a vertical slide and to provide means for attaching a spout or chute in front of said opening to discharge grain from the car.

Still another object of the invention is to rovide a simple, strong and durable door for grain cars in which provision is made for quickly attaching a spout to an opening in the door for discharging the contents of the car.

These and other objects are attained by means of the construction illustrated in the drawings, in which Figure 1 is a longitudinal sectional view, showing the door in elevation. Fig. 2 is a longitudinal sectional view on the line 22, Fig. 1. Fig. 3 is a vertical sectional view on the line 33, Fig. 1. Fig. 4 is a front elevation of the door detached from the car. Fig. 5 is a detail perspective view of the discharge spout secured at each side of the opening in the door. Fig 6 is a detail section through the discharge spout and showing the manner in which the spout is detachably secured to the door. Fig. 7 is a detail section through the door, showing the manner of mounting the cogged rollers for sliding the door laterally. Fig. 8 is a detail section showing the manner of securing the up er end of the stay rod in front of the door. Fi 9 is a detail section, showing the pin for ho ding the door closed.

Referring to the drawings for a more par-.

ticular description of my invention, the numeral 1 designates the frame portion of a freight car of ordinary construction provided with door posts2, 3. The post 2 is slotted as at 4, and u on each side of said post is a metal wear-p ate or brace 5 bolted at its upper end to the upper portion of the car frame, as at 6, while the lower end is secured to a sill of the car. The post 3 is provided with similar wear-plates 7. The door consists of a body portion 8 provided with vertical braces 9, said braces extending be low the lower edge of the door, and journaled between the braces 9 are cogged rollers 10, said rollers adapted to engage a rack-bar 11 secured to the sill of the car. The door 8 is provided with a central vertical opening 12 and at the sides of said opening, metal guide strips 13 are provided between which a closure 14 is adapted to slide, said closure having a ring '15 secured to a metal strap 16 extending upward from the closure. A stay bar 17, Fig. 3, is seated at its lower end with in the sill as at 18, and the upper end of said stay bar is fitted to slide in a keeper-plate 19 secured underneath the longitudinal framepiece 20 of the car, said keeper 19, provided with a slot in which the upper end of said stay-bar is seated. A winged nut 21 fits the threaded portion of the upper end of the stay-rod and is adapted to be turned into contact with the keeper 19 to hold said rod in position, said rod passing through the ring 15 to'hold the door closed. A handle 22 is secured to one end of the door and a locking pin 23, shown in detail in Fig. 9, passes through the door and through the post 3 to hold the door closed, said locking pin being suspended from a chain 24 secured to the outer portion of the car. Secured to one edge of the door is a guard-strip 25, said guard strip extending longitudinally of the cap and sliding between keepers 26 on the s1 prevent the grain from clogging the rack-bar 11 when the door is moved laterally to its open position. Adiagonally disposed post 27 is provided with wear-plates 28 and is slotted at 29 to brace the door in its open position when moved laterally on the rackbar 11. A removable discharge spout 30 is provided with hook bars 31 having backwardly extending hooks 32 which engage slots 33 in the guide strips 13, said spout having an inclined bottom 34 to discharge the grain when the closure 14 is open and said spout being detachably secured in front of said opening.

From the foregoing, the construction and operation of our car door will be readily understood and may be briefly described as follows. When it is desired. to discharge the The purpose of the guard-strip is to.

contents of the grain car, the spout 30 is secured in place and the closure 14. is raised, thus permitting the grain to pass out by gravity through the opening and over the spout. When the grain has been discharged to a level below the closure 14, the door 8 may be moved laterally upon the rack-bar 11 and the remaining contents of the car re moved through the door opening.

From the foregoing, it will be obvious that that a car door made in accordance with our invention will be strong and durable, will permit the attachment and detachment of a discharge spout and can be shifted laterally to provide a large opening for the discharge of the contents of the car.

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

1. A car door provided with an opening at the central lower portion thereof, guide strips secured to the door at opposite sides of said opening, a vertically sliding closure fitted to slide in the guide strips, a metal strap secured to said closure, a ring connected to said strap, a stay bar on which said ring slides, said stay bar being seated at its lower end. in the car sill and. its upper end being detachably fitted into a slotted keeper plate and provided with a winged nut, said guide strips provided with oppositely disposed slots, and a detachable spout provided with bars secured to the sides thereof, said bars having downwardly extending hooks upon their inner ends to engage said slots, substantially as described.

2. A sliding car door provided with an opening in the lower side and centrally of said door, guide strips secured at opposite sides of said opening, a vertically sliding closure for said opening, said closure being fitted into the guide strips, a metal strap extended upward from said closure, said strap carrying a ring, a stay bar upon which said ring slides, said stay bar being seated at its lower end in the car sill and its upper end being detachably fitted into a slotted keeper plate and provided with a winged nut, said guide strips being provided with slots, one at each side of each opening, and a removable spout provided with bars secured to the sides thereof, said bars having downwardly extending hooks at their inner ends to engage said slots, and means for holding the sliding door from movement, substantially as described.

In testimony whereof, we afIiX our signaturesin presence of two witnesses.
