HARTZELL FISHER, OF KANSAS CITY, MISSOURI, ASSIGNOR OF ONE-THIRD TO E. R. MARTIN,'OF KANSAS CITY, MISSOURI.

GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented July 25, 1905.

Application filed April 20, 1905. Serial No. 256,647.

To all whom, it may concern:

Be it known that I, HARTZELL FISHER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Grain-Car Door, of which the following is a specification.

My invention relates to grain-doors for railroad grain-cars.

Some of the advantages of my grain-door over others are it cannot be nailed to the door-jambs. It can be attached to a car at small expense. It can be attached to a car without cutting or disfiguring either of the door-j-ambs. With the present makeshift grain-doors the jambs are filled with nailholes or split and sometimes have to be replaced with new jambs.

The latch-levers with which my door is provided are superior, because they are absolutely secure. After they are disengaged the door can be raised by one man without the use of a bar. My latch-levers hold the door down as well as against the door opening or jambs.

Referring now to the accompanying drawings, Figure 1 is an outside elevation of my grain-door, a portion of oneof the jambs being broken away. Fig. 2 is an enlarged sectional detail taken on line a Z) of Fig. 1. Fig. 3 is a face View ofone of the concave guides. Fig. 41 is a face view of one of the convex bars which are secured to the door. Fig. 5 is an enlarged sectional detail taken on line 0d of Fig. 1.

My grain-door may be constructed of either wood or iron; but it is shown as constructed of wood. In its preferred form it consists of a large lower portion 1 and a smaller upper portion 2, connected thereto by hinges 3. Iron battens 1 and 5 are secured vertically to the two sections of the door, as shown. Secured to the inner side of each jamb 6 is a concave metalguide 7. A shim 8 is fitted between one side of the guide 7 and the jamb, as shown in Fig. 2.

Secured to the grain-door in position to engage the guides 7 are two convex metal slidebars 9. \Vhen the door is raised or lowered with grain in the car, these bars 9 slide in the grooves of the guides 7 with very little friction.

The upper section 2 of the door is provided with two latch-levers 10, pivoted at 12 and 12.

The lower section 1 of the door is provided with two similar latch-levers 13,.piv0ted at 1 1 and 14.. Each latch- lever 10 or 13 is made by doubling a fiat iron bar upon itself, forming a loop, handle, and sealing-opening 15. Near the other end the latch-lever is' bifurcated by the separation of the end portions of the bar, thus forming an arm 16, which lies close to the door, and an outstanding arm 17. To receive the ends of the inner arms 16, slots 18 are cut in the convex slide-bars 9. Thus when the end 16 of a latch-bar is thrown into one of said slots the part 16 is thereby strongly attached to the door. Slots 19 are cut in each guide 7 to receivethe ends 17 of the latch-levers when they are turned to the position shown in Fig. 1. As shown in Fig. 5, the slots 19 in the guide-bars? are made wider at one end, (in this case the lower end.) Thereby when the part17 of the latch-lever is forced up by pulling down on its opposite end the grain door will be drawn more and more tightly against the guide-bars 7.

To provide for locking the grain-door in position, two staples 20 are provided adjacent the handles 15 of the lower pair of latchlevers. The usual wires are passed throughsaid loops and through the staples and sealed in the usual manner. Thus the latch-levers cannot be turned without cutting the wires. (Not shown.)

It the grain-door be made of iron, the battens 4: and 5 may be dispensed with and the slide-bars 9 may be integral with the door.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An inside grain-car door comprising the door proper, convex metal slide-bars secured vertically to the sides thereof, said slide-bars having slots, a plurality of latch-levers mounted on the door, the outer ends of said levers being bifurcated, the bifurcated members nearest the door being adapted to enter the slots in the slide-bars, in combination with concave guide-bars secured to the door-jambs, said guidebars having tapered slots, the outer bifurcated members of the latch-levers being adapted to enter the slots in said guide-bars; substantially as described.

2. An inside grain-car door comprising the door proper, slide-bars having slots adapted to be engaged by latch-levers, concave guidebars secured to the door-jambs, said guidebars having slots adapted to be engaged by latch-levers; substantially as described.

3. An inside grain-car door comprising the door proper, slide-bars secured vertically to the sides thereof, said slide-bars having slots; a plurality of latch-levers mounted on the door, the outer ends of said levers being bifurcated, the bifurcated members next the door being adapted to enter the slots in the slidebars; in combination With guide-bars secured to the door-jambs, said guide-bars having" tapered slots, the outer bifurcated members of the latch-levers being adapted to engage the tapered slots in the guide-bars; substantially as described.

In testimony whereof I afitix my signature in the presence of two Witnesses.
