GRAIN-DOOR.

Patented Dec. 24, 1907.

- Application filed February 6, 1907. Serial No. 356.088.

To all whom it may concern:

Be it known that I, EDGAR BERESFORD GILLELAND, citizen of the United States, residing at Nevada, in the county ofVernon and State of Missouri, have invented certain new and useful Improvements in Grain- Doors, of which the following-is a specification.

The present invention appertains to doors for freight cars such as intended chiefly for hauling grain or other commodity in bulk, the primary object being to devise a closure which will at all times maintain a close joint tov prevent waste of the material and which will admit of the door being opened without necessitating mutilation, defacing, or otherwise injuring either the door or its facing, or parts-bordering upon the door opening.

The invention further provides novel mountings for the door which when the door is lowered or closed will retain the same securely in place and when the door is elevated a short distance, will permit of the said door clearing the guide-ways and swinging inward and upward so as to be held against the roof of the car out of the way.

The invention further contemplates peculiar lock means for securing the door at any elevation within the range of its vertical movements.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a front view of a car door embodying the invention showing the same in lowered position. Fig. 2 is a view similar to Fig. 1 of the inner side of the door, a side of the car provided with the door opening closed by means of the said door, the full lines showing the door closed and the dotted lines illustrating the position of the door when elevated sufliciently to clear the guideways. Fig. 3 is a sectional view illustrating the position of the door when swung forward beneath the roof of the car, held thereto out of the way, the dotted lines illustrating the position of the door when closed. Fig. 4 is a detail view of the door. Fig. 5 is a detail perspective view of one of the guide-ways. Fig. 6 is a detail view showing the manner of suspending the guide rods from the lower edge of the plate. Fig. 7 is a horizontal section on the line 05-00 of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same bent to overlap the upper and lower edges of the door to which they are attached. The ends of the door are inclined to give a wedgeshaped outline to the door, the incline being upwardly and outwardly, whereby the upper edge of the door is wider than the lower edge. Metal bars 2 are secured to the outer side of the door a short distance from the inclined ends and are adapted to make engagement with the inner side of the guide-ways in which the door is slidably mounted. The bars 2 may be of any'cross sectional outline and are preferably of T-form, the base affording firm connection of the bars with the door, whereas the rib projects outward to engage frictionally with a portion of the guideways. A lug 3 is bolted, or otherwise fastened to the" lower edge of the door and is adapted to receive the wear incident to starting or opening the door by means of a crowbar or other instrument, should it be necessary to pry the door open. The door is adapted to close upon the floor of the car he hind a metal strip 4 secured to the sill in any substantial way and arranged to sustain the outward pressure when the car is loaded. Handles 5 are applied to the door for convenience of manipulation.

The guide-ways 6 are located at each side of the door opening 7 and are inclined in conformity to the inclination of the ends of the door. The guide-ways 6 flare upwardly and are so arranged that when the door is closed, they snugly embrace opposite ends thereof. Upon opening the door which is effected by means of an upward sliding movement, the inclined ends of the door leave, or move away from the inclined guide-way 6 and when the door reaches acertain elevation in its upward movement, it clears the guideways and is adapted to be swung inward and upward beneath the roof of the car so as to be out of the way, any suitable securing means being employed to hold the door elevated as by means of one or more hooks 7 applied to the carlines. The guide-ways 6 are arranged upon the inner face of a side of the car at opposite sides of the door opening and may be of any construction so as to embrace opposite end portions of the door and prevent lateral movement thereof. As shown each guide-way consists of a plate 8 having a flange '9 at one edge and having its opposite edge portion rebent so as to embrace the end of the door. The plate 8 rests against the inner face of a side of the car, whereas the flange 9 extends along the side of the door jamb bordering upon the door opening so as to protect and reinforcethe same. The guide-ways 6 correspond in length to approximately the height of the door and if preferred each guide-way may be formed with an extension 10, either constituting a part thereof, or made separate therefrom and attached to the upper portion of the door jamb so as to reinforce the same upon the sides facing the door opening and the inner side of the car. The upwardly flared arrangement of the guide-ways 6 admits of the door clearing the same when elevated with the result that the door may be swung upward and secured to the roof of the car so as to be entirely out of the way.

The guide rods 11 are pendent in the door opening from the plate and are loose at their lower ends so as to swing inward. These guide rods may be of any form in cross section and may be connected at their upper ends to the plate of the car in any substantial manner to admit of their swinging inward. The guide rods may be attached directly to either the inner side of the plate as indicated most clearly in Figs. 2 and 3, or to the lower side of said plate as shown in Fig. 6. Vhen the guide rods are attached to the inner side of the plate, it is necessary to have their upper ends bent at an angle so that the rods 11 may enter the door opening. The door is rovided near each end with guides 12 which are in the form of eyes, or loops to embrace the guide rods 11 and retain the door in proper position thereon in its sliding movements. The guides 12 are provided in pairs and are located near the upper edge of the door. Suitable stops 13 are provided at the lower ends of the guide rods 11 to engage with the lowermost guides 12 and prevent displacement of the door from said guide rods when swung inwardfrom the door opening. The stops 13 may consist of a ring, key or the like, fitted into a transverse opening formed in the lower end of each guide rod, thereby admitting of the stop being removed when it is required to disengage the door from the guide rods for any purpose.

In order that the door may be secured when elevated to any required position the following lock means have been devised, the same comprising a rod, or bar 14, a handle 15 projected outward from the said rod or bar, eyes 16 at the ends of the rod or bar to receive the guide rods 11 and bearings 17 in which the said rod or bar 14 is mounted. The eyes 16 at the ends of the rod or bar 14 constitute clutch members which are adapted. to grip the guide rods 11 and secure the door in an adjusted position with reference thereto. The guide rods 11 are either gripped or released by turning the rod or bar 14, the same being accomplished through the instrumentality of the handle 15. The rod or bar 14 is adapted to be subjected to a certain de gree of torsional strain, whereby the clutch members are enabled to firmly grip the guide rods and yet admit of the handle 15 being moved so as to come in contact with the outer side of the door and to be secured there to. WVhen the handle 15 is moved outward at its free end, the clutch members 16 release the guide rods, thereby permitting the door to be raised or lowered and when properly adjusted, the door is secured by moving the free end of the handle 15 towards the door, thereby causing the eyes or clutch members 16 to assume an angling position with reference to the guide rods, with the result that they grip said guide rods at opposite sides and hold the door in the desired adjusted position. The handle 15 has a slot 18 through which a staple 19 applied to the door passes, a pin 20 being slipped through the staple so as to confine the handle. The in 20 may be connected to the door by a s ort chain to prevent its misplacement. Obviously the pin 20 may be replaced by a hasp lock or other form of fastener so as to secure the parts should it be required to prevent surreptitious opening thereof.

When the door is closed, it rests upon the floor of the car just inside of the horizontal strip or bar 4, thereby obtaining a close fit at its lower edge. The vertical battens near the ends of the door extend into the door opening and touch the door jambs without binding, thereby preventing end play of the door and securing a comparatively close joint at this point. The bars 2 touch the inner faces of the plates 8 of the guide-way 6, thereby adding to the closeness of the joint. The inclined ends of the door are embraced by the guide-way 6, the fit being such as to preclude the waste of grain or other commoditywith which the car may be loaded. When the door is closed, it is secured by the lock means hereinbefore disclosed. To open the door to effect unloading of the car, the handle 15 is released and moved outward to effect release of the guide rods 11 from the gri ping action of the clutch member 16. T e door may now be moved upward either by upward pressure applied to the handles 5 or by prying u ward upon the lug 3. The door may be held at the required elevationby swinging the handle 15 towards the door and securing the same by means of the pin or fastening 20, thereby causing the clutch member 16 to grip the guide rods 11. After the car has been emptied and the door has been moved upward a distance to clear the guideways, it may be swung inward and upward beneath the roof of the car and secured by means of the hooks 7 a in the manner stated.

Having thus described the invention, what is claimed as new is: i

1. In combination with a sliding door a guide rod therefor, and lock means for securing the door at any adjusted osition, said lock means consisting of a locliing rod mounted to receive a movement around its axis and provided with a clutch member to grip the said guide rod and meansfor turning said rod and securing the same in an adjusted position.
