GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent N 0. 768,346, dated August 23, 1904.

' Application filed February 20, 1904. Serial No. 194,574. (No model.)

To (ZZZ whom, it may concern:

Be it known that LWEBSTER L. SHIEss, a citizen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Grain-Car Doors, of which the following is a specification. I

The object bf my invention 'is a slidable door adapted for use on grain-ears which can be readily opened and the operation of which can be easily understood.

A further object is to provide a door of this kind of few parts, not likely to hang or get out of order, and which shall also be provided with an opening adjacent the bottom covered by a slide through which a portion of the grain can readily escape,whereby room is provided within the car, so that the door can be swung inward. I With many of the forms of doors now in use on grain-cars it is found impossible to get the door open when the car is filled to the roof with grain, as many of the cars are, and

, the grain-door is consequently broken at the showing the keeper secured to the door.

bottom to permit a portion of the grain to flow out.

My invention consists of the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in which Figure 1 is a perspective view of my door in position. Fig. 2 is a sectional view of the upper portion of acar, the doors being shown open. Fig. 3 is a detail sectional View showing the means for locking the door in an open position. Fig. 4: is a detail perspective view Fig. 5 is a horizontal section through one of my doors, taken immediately above the slide carried by the said door. spective View of a portion of my door, showing a portion of the slide and the means for securing the end of same. Fig. 7 is a vertical section on the line 7 7 of Fig. 5, a brace bar being shown in elevation. Fig. 8 is a detail sectional View on the line 8 8 of Fig. 6.

' Fig. 9 is a horizontal transverse section through the door-jamb immediately above the door. I

In Figs. 1 and 2 the usual outer freight-car- Fig. 6 is a detail pershown in Figs/2 and 3.

two hooks D are door is removed, as the same is not a part of this invention.

In the drawings, A represents a grain-car of any desired construction. sides of the doorways in the said car an iron plate B is secured to the door-jam'b, the plates secured in the same doorway facing each other.

This plate is slotted, as shown at B, and the door-jam'b is vertically slotted at A to aline.

bears on and overlaps theinner sides of the door-jamb, and the door is of such a height as to extend from the bottom of the car to a point adjacent the lower end of the slot B. From the drawings it will be noted that the door 0' overlaps the lower portion of the plates B.

Arranged on the outer face of the door C, adjacent the upper edge of the door C and adjacent the door-jambs, are plates C, which plates have an outwardly-angled portion 0 and this portion or arm is bent inwardly and extends into the slot B, which is of less width than the recess A, and the inner end of this arm C is bent inwardly, forming a hook member G which engages the slotted portion of the plate B. To the outer face of the door, adjacent its lower edge, is secured a keeper D, consisting of an angled plate bent upon itself, as at D, and flanged along the side edges on one side of the bent portion D. This plate is secured to the door, so that the angled portion fits the door edge and overlaps the lower edge of the door, the bent portion forming a shoulder adjacent the door edge. A book D is secured to a beam in the roof of the car and is adapted to engage the shoulder D when the door is raised and swung inward, as Where; two. of my doors are used on a car, as is usually the case, provided, one for each door.

The door G is strengthened by suitable brace-bars O, and adjacentthe lower edge of the door is formed a horizontal slot E, intersected intermediate its ends by the vertical On the opposite brace 0, whereby two openings for the outflow of the grain are formed, and intermediate the ends of the slot and adjacent each end are arranged vertically guide-strips E some distance above the slots, and the central strip is depressed, as at E, at a point intermediate its ends. Running along the lower edge of the slots E is an outwardly-extending flange E*, and resting on this flange and sliding between the door C and the guidestrips .E' is a slide E, which when resting on the flange E* covers each of the slots E. Handles E are secured to the outer face of the slide E, by which it may be raised, and its vertical movement is' limited by the guidestrips E. The depressed portion E of the central strip causes that strip to engage the upper portion of the slide when the slide is in its lowest position and to engage the strip adjacent its lower edge when in its highest position and by binding on the said slide serves to hold it in an elevated position when raised and to prevent vertical movement of the slide when lowered by reason of jolting of the car, a positive movement being required to shift the slide E from one position to another.

On the inner side of the door-jarnbs are arranged hook members F, between which the lower portion of the side edges of the door work when the door is lowered, the door fitting between the hooks and the door-jambs, and the door is thus prevented from swinging inward away from the door-jambs when in its lowered or closed position.

The operation of the device above described is as follows: When the car is filled with grain, the slide E is raised and some of the grain permitted to escape through the slots E until a suflicient amount has been removed to allow the door to swing inward. The door shoulder D, formed on the keeper-plate D,

carried by the said door, The door is now held in an elevated position practically parallel to the floor of the car, as shown in Fig. 2.

The fact that the door overlaps the doorjambs on each side serves to make a graintight joint, and it will also be noted that the door C itself does not work in slides or guideways, and so cannot jamb, and that no rollers are employed with corresponding grooves or tracks. The construction of the door is therefore very simple and should any part be broken can be readily replaced or repaired, and the door can be operated by any one able to lift the door vertically, no prior study of complicated fastenings and parts being required.

In order that the slide E may be prevented from longitudinal movement along the flange E on the end strips E, I have shown a flange E, bent inward, as shown most clearly in Fig. 6.

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

1. A grain-ear door of greater width and less height than the doorway adapted to be moved vertically in said doorway and then swung inwardly, means for movabl y connecting the door to the door-jambs, a horizontal slot formed in the door adjacent its lower edge, vertical guide-strips arranged on the door and extending from below to a point above the said slot, a flange along the lower edge of the slots and a slide adapted to rest on the flange and to close the slot, and adapted to be moved vertically between the door and the guide-strips to uncover the slot, as and for the purpose set forth.

2. The combination with a grain-ear having a doorway, of a door of greater width than the doorway and of less height, the said door being horizontally slotted adjacent its lower edge, means for slidably and pivotally connecting the upper portion of the door to the door-jambs, an outwardly extending flange along the lower edge of the slot, vertically arranged guide-strips extending from said flange to points above the slot one of said strips being depressed intermediate its ends, a slidable plate resting on the said. flange and adapted to move vertically beneath the strips and in contact with the said depressed portion of one of the strips, and means for locking the door in an elevated position when swung inward and upward.
