Specification or LettersPatent.
Patented March 23, 1909.
Application filed. July 21, 1908. Serial No. 444,609.
T 0 all whom it may concern:
Be it known that I, JosEPH E. OHANTLER, a citizen of the United- .States, residing at Lamar, in the county of Prowers and State of Colorado, have invented a new and useful Folding Grain-Door, of which the following is a specification.
This invention relates to grain doors and has for its object to provide a door primarily for grain transporting cars but which may be used for other purposes where found convenient. To this end the door or closure-is made of a series of superposed horizontal strips or boards, one half of which are hinged to a vertical rod, pivoted at its upper end, on one side of the door frame, and the other half of said boards being hinged to a similarly disposed rod on the other side of said door frame. Theseveral stripsor boards swing inwardly and when closed overlap the opposite vertical rod to prevent the door being forced outwardly or permitting the esca e of grain from the car. When loading the ower board is first closed and the others in succession until the caris filled, but when unloading they are openedin reverse order. After a carhas been finally emptied the vertical rods are swung laterally or in the direction of the ends of the car and there sustained each by a hook near the top of the car. The boards or strips are also swung upwardly toward the center of the car and held close against the roof by a pivoted bar upheld by a hook. The pivots of the vertical swinging bars are connected by a cross brace to hold them permanently in position.
With the above and other objects in view the invention consists of thenovel construction, combination and arrangement of parts hereinafter described more in detail and illustrated in the accom anying drawing forming a part of this specification in which Figure 1 is a,vlew of the improved door as seen from the inside of a car, a portion of which is shown. Fig. 2 is a vertical section on the line 2-2 of Fig. 1, and Fig. 3 a horizontal section on the line 33 of the same figure. Fig. 4 is a detail view of one of the latches utilized for holding the door in closed position.
Like reference characters are used for the same parts in all the figures.
In the drawing, A indicates a car, the enis both strong and simple.
trance to which is closed by a door B the subject of this inveption.
Pivoted on each side of the car near the roof are two rods 1 and 2 which normally hang downward therefrom within the car and behind the door frame 3 as shown. The upper ends of said rods are slotted to move a short distance endwise on pivots 4 connected by a brace bar 5. The rods 1 are held in place on their pivots by nuts and washers as shown or by other convenient means. The lower ends of the rods 1. and 2 are bent sharply near the bottom of the car in a direction away from the ends of the lowest section 6 to prevent said sections from falling off or being unlawfully removed from the rods.
The door B in the present instance is composed of four boards or sections 6 two of which are hinged to the rod 1 and two to the rod 2 so that when swung open the hinged sections on rod 1 will be moved to the right and those on rod 2 to the left. The hinges 7 here shown are made of metal plates doubled upon themselves to embrace the rods 1 and 2 and be riveted or'bolted each to a section 6, their lengths being equal to the width of said sections. Other types of hinges may be used if desired, but the one shown and described The ends of the sections 6 on which the hinges are fastened are curved to fit the rods 1 and 2 and at their opposite ends the outer part 8 is cut away to overlap the rods against which they abut when closed. The top of each section 6 is curved or has a tongue 9 thereon to fit into a groove 10 in the under edge of the section immediately above, a construction which ties the several sections together as a solid door when the car is filled with grain and prevents the latter escaping in transit. The construction of thehinge joints and the overlapping of the vertical rods 1 and 2 by the outer ends 8 of the sections 6 also close any openings through which grain could pass.
Each door section 6 is provided with a fastening 11 for holding said section in closed position; hand holds 12 are also cut in the inner side of each section by means of which it may be raised sufficiently high to disengage the groove 10 in its lower edge from the tongue 9 on the upper edge of the section below, so that the raised section may be swung against the inside of the car, giving free access thereto. After the car has been em tied and it is desired to dispense with t e grain door, the rods 1 and 2 are swung toward the ends of the car, away from the door opening, until their lower ends 13 are near the roof of the car in which position they are held by a hook 14 projecting from the side of the car.
Depending from the roof beams of the car A on each side of the door opening and near the center of the car is a hinge member 15 to which. a supporting rod 16 is hinged and held out of the way by a hook 17. After the rods 1 and 2 have been raised and placed on the hooks 14 the door sections on each rod are swung upward with their respective rods as pivots and are supported in horizontal position by the rod 16 the latter being first disengaged from the hook 17 in order to permit this operation.
The lower door section 6 is provided at its center with a small openin 18 closed preferably by a slide 19 having a linger piece for moving it. This small opening will be used at mills, elevators etc., for starting the grain from the bottom of the car when it is full, and. thus takes the strain oil the high door of the car. When the car is not filled so high as to cover or partly cover the uppermost door section, the opening 18 and the slide 19 can be dispensed with.
As shown in Fig. 1, the rods 1 and 2 may be provided with an. extension. at 13, provided With a notch 13. This extension is designed to fit within and to engage a keeper, but can be released from the keeper by raising the extension or sliding the rods 1 and 2 longitudinally. This keeper and extension are particularly useful, in that they will prevent the door from becoming displaced if the same be left loose. A hanger 20, can be connected to one of the roof beams of the car for the purpose of holding the door-panels against upward movement when the door is open.
