GRAlN-CAR DOOR.

Application filed. .Tune 30, 1922, Serial No. 571,899. Renewed .Tune 18, 1923.

To all whom t may concern: n

Be it known that l, ANTON Poironnr, a citizen of the United States ot America, residing at VVyndmere, in the county oi Ftichland and State of North Dakota, have invented certain new and useful improvements in Grain-Car Doors, ot which the Yfollowing is a specification.

rlhis invention relates to certain new and useful improvements in grain car doors, and has particular reference to a door t the sliding type that is adapted to be moved upwardly to occupy a position beneath the roof of the car when the doorway is opened.

The invention embodies in a sliding grain car door of the above type, a door including a plurality of hingedly connected panel or slat members slidable in perpendicular guide ways adjacent the side door openings of the car, with the panels movable relative to each other and slidable into a curved guideway adjacent the root of the car when in an open position. j

A further obj ect of the invention is to provide a sliding grain car door formed of hinged panel sections with a drum and cable mechanism associated therewith for operating the same.

With these general objects in view and others that will appear as the nature of the invention is better understood, the saine consists in the novel construction, combination and arrangement ot parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

ln the accompanying drawings forming a part of the application and in which like designating characters reifer to corresponding parts throughout the several views:

Figure 1 is a vertical sectional view of a freight car equipped with the present form of improved sliding door,

Figure 2 is a vertical sectional view taken on line ll-ll oit Figure 1 showing the sliding door formed of hinged panel sections and the shaft supported drums with the cable connections between the sliding door and the drums, j

Figure 3 is a sectional view taken on line IiP-lll of Figure 1 showing one of the sliding doors in its lower closed position with the trap door in the top of the car permitting access to the drum operating mechanism,

Figure s is a fragmentary perspective view of one of the guides for the sliding door,

Figure 5 is a fragmentary front elevational view of a modified form ot door construction showing overlapped panel sections and the link connections between adjacent panel sections,

rFigure 6 is an edge elevational view of the door shown in Figure 5, and

Figure 7 is a fragmentary iront elevational view of another modified 'form of door showing flexible rope sections between adjacent panel sections.

Referring more in detail to the accompanying drawing, and particularly to Figures 1 to li, there is illustrated a grain car embodying a floor 1, side and end walls 2 and 3 respectively, and the usual slanting root sections 1. The opposite side walls 2 are provided with door openings 5 closed by outwardly positioned sliding doors 6 oit ordinary construction. is shown in Figure 3, the sides ot the door opening 5 receive perpendicular posts 7 cooperating with the grain door to be described.

The grain door is :termed of panel sections 8 held together at their adjacent edges as at 9 and are vertically slidable at a point adjacent the inner sides of the door opening 5. A guide trame is associated with each side of the door opening and embodies an angle strip having a side section 10 secured tothe side wall 2 adjacent the post 7 and being curved inwardly at its upper end lor attachment to the adjacent root' section 4 as shown in Figures 1 and 2, rThe other side section 11 of the angle strip overlies and is spaced from the post 7 as shown in Figure 3 and is coextensive with the side section 10 and terminates at the longitudinal center or the car roof as shown in Figure 1. As shown in Figure t, the guide strip is preferably formed of a single piece, being of inverted substantially U-shaped torination. The sectional door is slidably mounted with the side edges overlapped by the side sections 11 of the guide strip and has means associated therewith for raising and lowering the same.

independently operating door mechanism is associated with each door, and includes a shaft 12 having brackets 13 depending from the roof sections 4 adjacent the door opening 5, and has fixed to each end thereof a winding drum 14, a cable 15 has one end thereof secured to the drum 1li while the other end lli) is secured as at 16 to the upper panel section 8 of the door as shown in Figures 1 and 2. One end of the shaft 12 carries a cranl handle 17 by which the shaft and drums 14 supported thereby may be rotated. To permit access to the crank handle 17, the roof section 4 is provided with a trap door opening 18 closed by a cover 19 as shown in F igure 3, the crank handle 17 being disposed directly beneath the trap door opening 18 and readily accessible for operation.

F rom the above detailed description of the device. it is believed that the construction and operation thereof will at once be apf aarent it bein@` noted that when either of l 5 D the covers 19 is removed from the trap doors 18, eitherl of the shafts 12 associated with the opposite sliding doors may be operated by the crank handle 17 for raising the sectional door upwardly from the door opening 5 to cause the same to occupy a position adjacent uthe roof section l-'as shown in Fig# ures 1 and 3, the sliding doors 6 being of the ordinary construction and operated in the usual manner eXteriorly of the car. The weight of the sectional door will cause the same to be lowered to its closed position, and the reverse rotation of the shaft 12 and unwinding of the cable 15 from the drum 14; will also permit the lowering movement of the door.

Figures 1 and 2 show the panel sections of the door having the adjacent edges in abutting relation, while Figures 5 and 6 show a modified form of door wherein the adjacent edges of the panel sections 8a are arranged in overlapping relation. The connecting means between the panel sections, as shown in Figures 5 and 'embody link members secured to clips 21 carried by the ends of the panel sections 8@l with the adjacent ends of the link members loosely connected together,

permitting` relative movement of the panel sections S1 when the saine are received in the upper curved sections of the guide strips. The operating cable 15 is secured to the upper panel section 8 as is shown inr connection with the preferred form of the invention.

In Figure 7, the panel sections 8a are arranged in overlapping relation, while the ends of the panel sections 8a are provided with clips 21 that confine arope section 22 having spaced balls secured thereto, one at each end of the clip having the intermediate cord portion between the panel sections 8a permitting relative movement of' the panel sections.

While the form of they invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus fully described the invention, what i claim as new 1s In a door for grain cars, a car providedwith side door openings, guide strips Vfor, each side door opening extending inwardly vat their upper ends and engaging the roof of the car, a panel door slidable in the guide strips,y a shaft journaled adjacent the car roof, a drum secured to each end of the shaft,a crank handle secured to one end of the shaft, cable connections between thedrums and the upper panel of the door, and said car roof having a trap door opening therein overlying the crank handle carried by said shaft. j

ln testimony whereof I affix my signature.
