SIDE-DOOR-CAR CONSTRUCTION.

Application filed August 2,

To all whom it may concern:

Be it known that we, OTIS TIFFANY GREGG and VILLIAM BURR GREGG, citizens-of the United States, residing at Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Side-Door-Car Construction; and wedo declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of thisv specification.

Our invention relates to side door cars more particularly of the type of cars for transporting cane'but applicable for'other uses. The object of the invention is to-provide a construction. characterized by simplicity and strength'in its various parts and by which the cost of production is materially decreased. To the accomplishment of V the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, references being had to the accompanying drawings forming a part hereof, and in which- Figure 1 is a side elevation of a portion of a car formed according to the. present invention, and showing the side unfastened and swung partially open; I

Fig. 2 is a perspective of'a portion of the car on a larger scale, andshowing the side fastened in its closed position;

Fig. 3 is a section on theline 3 -3 of Fig.

1 showin the manner of hinging the upper ends of the bars constituting the side door; Fig. 4: is a section on the line 4-4 of Fig. 1 showing the manner of securing the lower ends of the bars constituting the side door to the bottom rail of the door.

In Fig. 1 is illustrated a type of car which has a central partition dividing the car into two compartments, each compartdoor s, but. the invention is the same whether applied to'that or other type of construction. I Y

In the drawings thenumeral 1 designates the floor frame of the car of any approved type, and 2 designates the sides of the car Specification of Letters Patent.

and 3 the ends and 4 the central partition of the'car body frame are preferably of commercial Z shaped metal bolted or riveted at suitable points to theupper ends of upright posts or members 6 which preferably are of commercial L shaped metal, although they may be other formation, the lower ends of the uprights being suitably bolted or riveted to the metal side sills 1 of the car bot- T he side doors are each formedof a desired number of upright bars 7 preferably formed of commercial L shaped metal, the upper ends of which are pivotally connected or swung by bolts ,8 passed through metal brackets 9 attached by rivets 10 to the under faceof the horizontal member or'web of the Z shaped top belt-rail 5 as shown in Figs. 1

and 8, while the lower ends of the bars are secured by bolts 11 or otherwise to'L shaped brackets 12 secured preferably'by rivets 13 to the bottom rail 14 of the door which is preferably formed of channel iron as shown. The top belt-rail 5 is disposed or positioned so that while the two flanges thereof will-be vertical, for the purposes of the present invention, the outer flange is made to extend downwardly and the inner flange upwardly. This is done so that with the stakes, forming part of the door, swung. from the belt-rail as hereinafter specified the maximum strength of the Z belt-rail will be availed-of to resist the strains which occur,

and the downward and outward pressures which are developed will be so distributed that the downward pressure will'be approximately along the vertical centerline of the Z belt-bar and the outward pressure approxibar and thusavoiding the strain of twisting or torsion exerted on the belt-bar as the result of the downward and outward pressures developed under other constructions.

Under the improved construction the upper portions of the stakes constituting a portion of the door bear against the'inner edges of the hinging brackets at a point quite close I mately along-the horizontal line of the same ficiently below the lowest part of the downwardly extending outer flange of the beltbar to permit the doors to open to the necessary extent before the stakes strike the lower edge of the outer downwardly extending flange of the belt-bar. These features of construction cause the downward pressure to be substantially through the center-line of the belt-bar as indicated by the line ct-a of Fig. 3, and the outward pressure to be substantially along the horizontal line of the bar as indicated by the line bb, thus avoiding the twisting or torsional action on the. bar as previously mentioned; and the positioning of the Z belt-bar with its outer flange extending downwardly and its inner flange upwardly making possible the utilizing of the maximum strength of the bar to resist the strains imposed'where the construction comprises generally a Z belt-rail from which is swung a h nged side-door and the belt-rail disposed with its flanges ex-- tending oppositely to what is provided for in this improved construction. With the parts arranged as herein described the upper ends of the stake bars'are cut away or formed on an incline as indicated at 0 so that the stakes may swing without interference with the rivets 10 by which the hinging brackets 9 are supported from the belt-bar. In the manner described a specially strong and comparatively inexpensive construction of door is provided and onewhich is easily 'manipulated in opening and closin The door is locked or fastened in its closed position by a link lever 15 preferably formed of looped parallel arms passed through an eye 16 of a bracket 17 bolted to the sill of the car and having its upper ends welded together so as to provide a lever simple and strong and capable of securely holding the door closed against pressure exerted from within the car or otherwise.

Any'suitable lock or holder for effecting locking engagement between the lock lever and door may be employed but the preferred construction on account of strength and security consists of an open faced metal pocket I 18 provided with a swinging latch 19 adapted to be tilted on its pintle 20 so that its free end may engage or interlock with'the nose or catchr21 of the holder and securely hold the lever in thepocket when the door is in its closed position. This metal pocket or holder is bolted or otherwise secured to a base-plate 22 preferably formed offchannel iron and which is secured by bolts 23 or otherwise to two of the upright bars constituting a part of the door as shown. When the door is to be opened the latch 19 is lifted from out of engagement with the nose 21 of the pocket and swung on its pivot pin or pintle 20'so as to'open the face of the pocket and permit the lever to be lowered or dropped and then the door is free to swing obtained with a saving of'cost in construcoutward as indicated in Fig. l and by dotted line in Fig. 3 so that .the cane orother contents of the car may be. discharged or dumped. 7 a I J:

It will be observed that the'locking lever 15 is connected to the side sill of the car by an eye-bolt so that the lever is free to swing laterally as well as vertically and thus danger of accidental bending of the lever is avoided; 'also'that by attaching the locking lever at one end by a substantially universal joint to the car side sillso that it may pass over the lower rail ofthe door and have its upper end fastened to the door'above the bottom rail and about substantially centrally contributes to greater ease in releasing the locking lever when the car is loaded. It also dispenses with the necessity of employing a numberof lock fastenings for the door and thus the secure locking and release is expe 'dited and otherwise facilitated and it is made possible to construct the several parts heavier than otherwise so that simplicity and increased strength and durabilityxare tion. h V I y We have illustrated 'a'nd described with particularity the preferred details of the several parts but changes may be ma do without departing from the essential features of the invention. y
