CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 461,739, dated October 20, 1891.

Application filed April 2, 1891. Serial No. 387,454. (No model.)

To all whom it may concern.-

Be it known that we, JOHN W. CRUMBAUGH and LEANDER G. PRATER, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Car-Doors, of which the followingis a specification.

Our invention is in the nature of animprovement upon the car-doors for cattle-cars patented by usDeccmber 30, 1890, No. 443,956; and it consists in the peculiar means for adjusting and operating the doors in connection with the bridge, as hereinafter shown and described.

Figure 1 is a side view of the door closed. Fig. 2 is a perspective View of the same open and with the bridge in place, and Fig.3 is a vertical section with the door closed and the bridge in place as a cross-bar.

X represents the car-body, having upon its side an opening for a door of about five feet wide. At the sides of this opening are hung the double door-sections A B, two upon each side. The outer ones A of the door-sections are hinged to the car in a peculiar way and have a parallel swinging movement, swinging integrally from a position in front of the opening to a position alongside the car-body and away from the front of the opening and moving from the plane of the side of the car away from the car and then back to the side of the car again. This is effected bya set of crankshafts a b a, each having the same radius or throw, so as to work in unison. The first one of these crank-shafts a extends the whole length of the door and is double-i. a, it has a crank-arm at each end, which are pivoted in bearings a on the car, while the body of the shaft turnsin bearings a on the door-section A. The second crank-shaft 1) turns in a bearing 11 on the car, and also in bearings a on the door, and the third crank-shafts turns in a bearing a on the car, and also in bearings c on the door. These crank-shafts are each placed out of alignment, so as to give the door an integral or parallel swing, and the shaft 0 is made to extend nearly the full length of the door and forms, also, the pintlerod or axial shaft, about which the radiallyswinging door-section B turns by means of its hinge-bearings d, which are so arranged on the pintle-rod as to permit this door-section B to be raised, if necessary.

In the edge of each door B there is arranged a long bolt 0, adapted to fit into eyes or keepers e e on the door-sill when the doors are closed, or into the eyes 6 e when the doorsections are open and parallel to the car. I) is a hasp on one of the doors B, which is adaptedto fit over a staple D on the other door B and be locked by a pin D This latter has on its rear side an eye f, that slides over a vertical guide-rod f, which keeps it always in place. This pin has a crooked upper end for lifting it and a perforated lower end for securing it in the staple. Upon the car, at the middle of the dooropening, is a flanged plate g, which prevents the door-sections B B from being lifted after they are closed.

E is the combined bridge and cross-bar, which has the same function as in our previous patent-i. 6., it forms a bridge between the car-floor and the platform, over which the cattle may walk without danger of falling between and breaking their legs, and at other times it is hung up across the doorway, as in Fig. 3, and forms a crossbar, which prevents the cattle from pressing against and straining or bursting open the doors. This bridge has at one edge the slotted ears h, by means of which it is. hung up in the notches h in the door-jambs, and the slots in these cars serve as keepers or receptacles for the bolts 0 of the doors when the latter are adjusted, as in Fig.2. At the other edge of the bridge is a long rod is, having eyes Z at its ends, which encircle vertical rods m, set in the door-jambs, and which serve to make a loose sliding connection between the bridge and the door-jambs, that allows. the bridge to be laid down upon the floor, as in Fig. 2, or be raised to form a cross-bar, as in Fig. 3, without ever losing its connection with the car. In constructing the notches h and the rods m in the door-jambs we form or adjust these in false jambs J, which are securely bolted, screwed, or nailed inside the ordinary jambs. This prevents the cutting away of the jambs and gives increased strength to these parts. This construction'al'so permits our door to be applied to cars already in use without material alteration of or injury to the same.

G are metal clips or lugs placed on the inside of the swinging doors l3 and adapted to bear when the doors are closed upon the top of the red hot the cross-bar and hold it down in its supporting-notch, so that it cannot be raised out of place by the cattle.

The advantages of this form of door are as follows:

First. The doors when opened only swing one-fourth the width of the door-opening, or onehalf the width of each double door, and it there is not room enough between the car and the platform to permit this the swinging sections D may be raised up over the platform.

Second. There are no sliding connections for the doors either at top or bottom and no danger of their action being obstructed by mud or straw from the car-door.

Third. The action of the bridge is rendered free in its adjustment, so that it cannot be obstructed by rubbish or freezing of the semifluid matters.

Instead of using two double door-sections, we may use only one double section and one single section. Our invention may also be applied to other constructions or compartments besides cars.

Having thus described our invention, What we claim as new is 1. The combination, with a car or other compartment, of a door made in two sections hinged together, and a set of crank-shafts connecting one of said sections to the car for a radially-swinging parallel motion, substantially as shown and described.

2. The combination, with the door-sections A and B, of a single crank-shaft c, forming the axial shaft or hinge connection between the door-sections and arranged also in a bearing on the stationary frame-work, substantially as shown and described.

The combination of the two-part hinged door A 13, having its section B vertically adj ustable, and the ear-body having a stop lug or plate g to hold said adjustable section down when fastened, substantially as shown and described.

4. The combinatiomwith the bridge or crossbar E, arranged to be held in notches in the jainbs of the car-door, of the doors H, having lugs G adapted to lock against the cross-bar and hold itdown in its notches, substantially as shown and described.

5. The combination, with the car, of the extra or false jambs J, having notches h and rods m and secured to the car, and the combined bridge and cross-bar E, hung upon rods m, substantially as shown and described.
