GRAIN-DOOR FOR RAILWAY-CARS- SPECIFIGATION forming part of Letters'latent No. 790,521, dated May 23, 1905.

' Application filedihfly 18,1904. Serial No. 216,926.

To all whom it may concern:

Be it known that I, KIsTEL OSEL, a citizen I of the United States, residing at St. Paul, in

the county of Ramsey and State of Minnesota,

. have invented certain new and useful Imsupports for the door and the means for locking the door in raised and in lowered positions.

To this end my invention consists in the features of construction and combination hereinafter particularly described and claimed."

In the accompanying drawings, forming part of this specification, Figure 1 represents a view of the door asseen from the outside of the car. Fig. 2 is a view as seen from the inside of the car. Fig. 3 is a vertical section on line :11 w of Fig. 2 with the door in lowered position. Fig. 4 is a similar view with the door in raised position. Fig.5 is a section on line y 3 of Fig.8. Fig. 6 is a section on line a z of Fig. 3. Figs. 7 to 9, inclusive, are detail views of a portion of the supports for the door; and Fig. 10 is a detailed view of a catch for holding the door in lowered position.

In the drawings, A represents a grain-door of known construction, provided at the top with a hinged flap 2. The flap 2 is preferably wider than the door, so that when in closed position it will extend across the posts, against which it is held by means of the U- shaped catches 4, loosely and pivotally secured to the sides of the posts by staples 5. As indicated bythe dotted lines in Fig. 4, the catches may be turned laterally, as it is evident will be necessary, in order to bring the ,forming a continuation of the rib 11. At the top the guide is turned upon the arc of a circle to the inner face of the post, where it is suitably secured. Upon the door. are secured the brackets B by means of bolts 14, each bracket being turned at a right angle with the door, as shown in Fig. 5. Loosely pivoted through the outturned end of each bracket 13 by a spindle 16 is a slide 15, having inturned flanges 17, which embrace the edges of the cesses 10. The slide 15 thus turns freely upon the spindle 14. Each-guide 8 is formed 1 at its top with a notch 18, long enough to receive within it one of the slides 15. The flanges 17 are of greater length than the body of the slide, so that when the door is in raised position the ends 19 of one flange will bear against the guide upon opposite sides of the notch 18 and the ends of the other flange will bear against the lower sides of the curved portion ofthe guide to prevent disconnection. In order to allow the slides to pass freely around the curved upper ends of the guides, I preferably cut away the corners of the slides, as shown in Fig. 7

In order to hold the door in raised position, I provide suitable depending hooks 20, having pivotal support from the upper beams of the car.

In operation the flap 2 is first turned back upon its hinges and the door then raised, the slides traveling upward upon the guides 8. The slides being freely pivoted will follow the guides around the curve at the top until the notches are reached, when they will drop by gravity into the notches, thus holding the door in raised position. The doormay then be swung back upon the pivots 16, as shown in Fig. 4, and secured in raised position by the the hinged end of the door so close to the plate 21 of the car that the door cannot be moved to carry the slides out of the notches until it has first been swung downward. Accidental sliding downward of the door upon the guides is thus prevented.

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

1. The combination with a car formed with corresponding guide 8 and fit within the rehooks 20. As shown in Fig. 4, this brings the door-posts, of a grain-door, a pair of vertical guides secured on the opposing faces of the door-posts and having inwardly-turned upper ends, the inwardly-turned upper end of each guide being formed with a notch in its upper side, and slides hinged to said door and formed with flanges embracing said guides, said slides being proportioned to drop into said notches when the door is raised.

2. The combination with a car formed with the door-posts, of a car-door therefor, a pair of Vertical guides secured on the opposing faces of the door-posts and having inwardlyturned upper ends, right-angled brackets secured to the outer face of the door, slides loosely pivoted to the outwardly-projecting ends of said brackets, said slides being formed with flanges embracing the edges of said guides, and means for interlocking said slides and the inwardly-turned ends of said guides when the door is raised.

3. The combination with a car formed with a door-frame, of a grain-door, a pair of verticalguides secured in the sides of the doorof greater length than the body of the slide,

for the purpose set forth.

4. The combination with a car formed with a door-frame, of a grain-door, a pair of vertical guides secured in the sides of the doorframe and having their upper ends turned inwardly upon the are of a circle, said inwardlyturned ends being each provided in its upper edge with a notch, slides hinged to said door and formed with flanges embracing said guides, said slides fitting in said notches when the door is in raised position, and said flanges being of greater length than the body of the slide, and downwardly-extending hooks for holding said door in raised position.

5. The combination with a car formed with a door-frame, of a grain-door, a pair of vertical guides secured in the sides of the doorframe and having their upper ends turned inward] y upon the arc of a circle, said inwardlyturned ends being each provided in its upper edge with a notch, right-angled brackets secured to the outer face of said door, slides loosely pivoted in the outwardly-tnrned ends of said bracket, inwardly-turned flanges carried by said slides for embracing said guides, said flanges being of greater length than the body of said slide, and said slides being proportioned to fit into said notches when the door is raised.

In testimony whereof I aflix my signature in presence of two witnesses.

KISTEL OSEL.
