FRANK S. INGOLDSBY AND JOSEPH R. BOWLING, OF ST. LOUIS, MISSOURI, ASSIGNORS TO THE INGOLDSBY AUTOMATIC CAR COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF WEST VIRGINIA.

DOOR FOR RAI LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 789,094, dated May 2, L905.

Original application filed August 25, 1902, Serial No. 120,923. Divided and this application filed December 5, 1903. Serial No. 183,856.

To (Li/l whmn it may concern.-

Be it known that we, FRANK S. INGOLDSBY and JOSEPH R. BOWLING, citizens of the United States, residing at St. Louis, in the State'of Missouri, have invented a certain new and useful Improvement in Doors for Railway-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The invention relates to certain improvements in doors for railway-cars, particularly such as are constructed of metal, the features which are peculiar to the invention being clearly disclosed in the specification and drawings of this application and being definitely set out in their essential combination in the claims, to which reference is hereby made for the summary of the invention.

Referring to the drawings, Figure 1 represents a side elevation of a portion of the car, showing the mannerin which our doors are applied thereto. Fig. 2 is an enlarged elevation of the door and adjacent portions of the car side. Fig. 3 is an enlarged transverse section of the car side, showing both doors in the position which they occupy when closed. Fig. 4 is a detail in horizontal section showing the lock for the upper door. Fig. 5 is an end elevation of the car, a portion of which is broken away, the parts therebehind being shown in section. Fig. 6 is a detail View of the means for taking the weight of the upper door off the rollersrwhen said door is closed.

Referring to the parts by letters. A designates the side of the car. The side is composed of two portions, a lower plate portion (0 and an upper slatted portion a". The plate portion has at the bottom thereof a girder, said girder consisting of a plate a, an upper angle-beam a, a lower angle-beam a, and reinforcing-strips a. At the upper portion of the plate a is an angle-beam a". At the top of the slatted portion is an upper chord a, and extending between said chord and anglebeam a are the slats a. Vertical posts a and obliques a extend between the upper chord a and lower portion of the plate-girder.

-to one side thereof to clear the same.

The details of construction of the side structure require no further description, the same being described and claimed in our application, Serial No. 120,923, filed August 25, 1902, of which this application is a division.

D designates a central longitudinal beam, and Facentral cross-beam. These beams may be of any approved construction, the construction shown being that embodied in our application Serial N 0. 120,923, hereinbefore referred to.

At the central portion of the car there is provided a doorway, which is closed by the doors P and Q. Extending across the top of the doorway is a plate a, to the opposite ends of which are connected the upper ends of the obliques or diagonals a adjacent to said doors. This plate bridges the space between the upper ends of said obliques or diagonals and strengthens the doorway at this point, such strengthening being made necessary by the omission of the plate 6/. Secured to the side of the car is a trackway a, said trackway extending sufliciently to one side of the doorway to permit the upper door Q to be slid entirely The vertical posts a nearest the center of the car side form the door-posts.

On the inner side of the car adjacent to the doorway is pivoted the lower door P, formed, preferably, of sheet metal with angle-strips p and riveted to it. This door when in vertical position abuts against the inner side of the corresponding posts a and makes a tight joint therewith, being held in place by the gravitylatches When the door is turned down in a horizontal position, as it may be, its inner edges rest upon the upper edge of the central beam and its upper surface is preferably flush with the upper surface of the angle-bar a. When the door is in its lowered or horizontal position, it will be observed that the horizontal member of the angle-strip p reinforces the inner edge of the door and extends its bearing-surface on the inclined beam and that the downwardly-extended member of said strip forms a second bearing for the door on said beam. In this position this door P makes a very convenient platform for rolling wheel-barrows for loading all around the floor. After the lower part of the car is sufficiently loaded in this manner the door is turned up into vertical position and held by the latches p, and the filling is continued through the doorway above this door or through the top of the car.

Above the door P is the door Q, made of vertical slats secured at their upper and lower ends to suitable bars 9 and q. At the upper edge of this door are provided straps (1 which bend over in a U shape, as shown, and carry on their inner sides rollers Q3. The roller and the inner edge of the strap occupy a trackway (0 which, as shown, is provided by a suitable Z-bar secured to the side of the car.

When the door Q, is in closed position, its lower end is swung into the doorway, and it is there held by bolts qf, which take behind the posts a The two bolts q are connected together by links g thus making a toggle, to the knuckle of which is connected the ring through which may pass a sealing-pin (17. This sealing-pin being in place prevents the withdrawal of the bolts, and hence holds the door within the doorway where it cannot move longitudinally. In this position the door inclines inward downwardly, so that the load may conveniently slide off of it in dumping the car, and the weight is borne, not by the rollers (13, but by the lower ends of the straps When, however, it is desired to open the door, the sealing-pin Q7 is withdrawn and the ring q drawn outward, thus withdrawing the bolts Q4 and allowing the door to swing outwardly. This brings its weight onto the rollers (1 so that it may be easily shifted lengthwise past the door-opening.

As will be observed from an inspection of Figs. 2, 3, and 5, the latches p are pivoted to the inwardly-projected flanges of the anglebar posts (0 there being only suflicient clearance between such flanges and the hook portions of the latches to enable the upper edge of the door P to pass therebetween, thereby making a tight joint between such door and the posts. As will further appear from an inspection of the above figures, when the door P is in its vertical position and the latches p are in engagement therewith said latches are locked in place by means of the bolts q, carried by the upper door, said bolts extending over the latches p and back of the inwardlyprojected flanges of the door-posts (0 By this construction the latches p are locked and the door P is retained in its vertical position. When the door P is in its lowered position, the hooks are held in a horizontal position by the pins 12 There are many advantages in closing the doorway in the manner above set out: First,

there are no unnecessary parts, and the lightest weight is obtained; second, by tilting the l upper door Q inward there can be no lodgment of material when the car is being unloaded; third, it is not necessary to use a false door in the inside of the car, as is the case when ordinary box-cars with outside doors are used for coke; fourth, the operation of opening the door is extremely easy and simple, while when locked it is securely held in place, the upper door being held between the posts a by its bolts and the lower door being held against these posts by the force of the load itself and by the latches p, and, finally, as heretofore stated, the lower portion of the door forms a very convenient platform for loading the car.

Having described our invention, we claim 1. A car having a doorway therein, a door adapted to close a portion of said doorway, a latch for holding said door in its closed position, a second door adapted to close another portion of said doorway, a bolt for locking said second door closed, said bolt being adapted to engage and lock the latch of the firstmentioned door.
