GRAIN-CARDOOR.

SPECIFICATION forming part of Letters Patent No. 289,445, dated December 4,1883.` Appiimfion filed Augst 2,1883. (No model.)

To @ZZ whom t may concern:

Be it known that I, FRANCIS POND, a citizen of the United States, residing in Hinsdale, in the county of Du Page and State of Illinois, have invented a new and useful Improvement in Grain-Car Doors, of which the following is a specication.

In grain car doors heretofore constructed great difficulty `is frequently experienced in opening the door when grain or other freight is piled against it, as such doors haveordinarily been so made that they can only be opened in one particular way.

The object of the present invention is to provide a grain-car door that may be opened in a variety of different ways, so that in any exigency it may be easily opened in some one of the different ways. In the present invention the door is hinged at one corner by a two-way hinge to an upright bent rod, which is hinged at top and bottom to the door-casing or side of the car. One of the upper corners of the door is supported by a bent quadrant-shaped rod secured at one end to the back edge of the door, near the top, and at its other end to the bottom edge of the door, near the middle therei ner of the casing, and the distance between the straightor vertical part of the rod and the casing is equal to the thickness of the door, so

that the door, when it is turned on its pivoted corner, may be turned back between the vertical rod and the casing or side of the car, and also so that the door may be opened or swung outward,` inwhich case the door rests between the vertical rod and the front edgeof the casing. By reason of the swinging of the bent rod on its pivots the door may reciprocate back longitudinally far enough to swing past the offset or grooved casing, in which it rits at its front end. By this ,means it will be seen the door may be swung vor opened either in- The bent or bitl ward or outward; or it may be raised vertitically upward and then swung either in' or out around the vertical rod; or its front corner may be raised and revolved in a vertical plane around its pivoted corner to the extent of ninety degrees, and then, if desired, swung or turned around the vertical rod as a hinge, so that the door may be opened or closed in a variety of different ways, as may be most convenient.

In the drawings which form a part of this specication, and in which similar letters of reference indicate like parts, Figures l and2 are side elevations of a device embodying :my invention, showing the door in different positions. Fig. Bis ahorizontal section, taken just above the quadrant-shaped rod. Fig. 4. is a sectional end view of the car, showing the door swung outward. Fig. 5 is a side elevation, showing the door partially turned on'its pivoted corner. Fig. 6 is a cross-section on line 6 6 of Fig. 5, showing the door in position when closed 5 and Fig. 7 is an enlarged sectional view of the universal or two-way hinge at the corner of the door. Figs. 8, 9, and l0 are horizontal sectional views, showing plans .of the door when `standing on its end and swung ,into a number of different positions,

and Fig. 11 is Va similar view of the door resting on its bottom edge.

In the drawings, A represents the door, B the casing or frame of the car, and C is the upright bent rod to which the door is swung. The rod C, at its upper end, has a bend or oii` set,`c, equal in length to the thickness of the door, and is pivoted to the frame of the car by the loop o at the interior corner of the doorcasing B.. Ihe lower end of the rod C it is preferable not to bend in this manner, but to secure it to a thin iiat horizontal metal arm, c, which is secured and pivoted to the frame or floor of the car by the pin c3 at the corner of the casing B. By employing the thin flat arm c2 the corner ofthe door does not require to be much eut out. l

The lower or pivotal corner, A', of the door is provided with a two-way hinge consisting of the metallic piece or knuckle D, secured to the door by suitable screws, which lreceives the pin d, the other end, cZ, of which is aknuckle IOG to receive the upright rod C, upon which it may slide freely, so that the door may slide up and down on the rod C. The lower corner of the knuckle or piece D is notched or cut out, as shown at d2, to the thickness of the flat arm c2, so that the lower edge of the door will rest fiat upon the door-sill or fioor of the car and permit of the rod C swinging on its hinges or pivotsc and c.

A rod, F, preferably quadrant-shaped, is secured at one end to the back edge of the door, near its top, and at its other end to the lower edge ofthe door, near its middle, so as to leave suici ent space between the rod and the side of the door for the vertical rod C. The ends of this rod are bent at right angles at e, and should be flattened out and countersunk in the edges of the door, so as to be flush therewith. They may be secured by asingle nail or screw when thus countersunk and bent around the edges of the door.

The casing B, at the front or free end of the door, is provided witha jam or shoulder, b,

for the door to t against, and a projecting facing b', thus forming a groove or guide for this end of the door, as shown in Fig. 3. It may be locked or secured by any ordinary lock or bolt-as, for example, a simple pin, F-passing through the casingand into the edge ofthe door. The slight sliding or reciprocating motion given to the doorby swinging the rod G on its pivots is sufficient to draw the door out from between the casing B and the facing or flange b', andallow it to swing open in either direction around the rod Gas a hinge. The door may also belifted directly upward, in which case the shoulder b of the casing and the facing b furnish a guide or way for one end of the door, while the rod C answers the same purpose for the other end of the door. After' the door has been thus raised it may be swung around the rod Casahingein either direction. There is sufficient space between the bent rod C and the door post or casing to permit the door to swing freely around said rod, whether the door stands on its end, as shown in dotted lines in Fig. l, 0r rests on its bottom edge, as shown in full lines in said figure. The bent rod C being also pivoted or hinged to the door-casing, the rod itself can swing around as the door is swung into different positions, and thus prevent the corner or edge of the door binding against the casing or door-post, as is illustrated in Figs. 8, 9, and 10.

G is a pivoted projection provided with a turned-up lip, g, and secured to the side of the car by a pivot or pin, for the purpose of supporting or holding the door when it has been thus opened. The support G is pivoted to the side of the car, so that it may be turned out of the way of the door when it is opened back in other positions than that shown in heavy lines in Fig. 2, and to prevent said sup port being knocked off or injured when the car is used for handling lumber or other freight than grain. The quadrantsshaped rod E serves to support or hold the door in its vertical plane when it is being lifted or turned-as, for example, as shown in Fig. 5-and when the door is being swung around the rod C as a hinge, whether it be in its horizontal position, as shown in Figs. l, 2, 4, or 6, or in its vertical position, as shown in dotted lines in Fig. 1. The bends e, at either extremity of said quadrant-shaped rod, serve as a hinge or knuckle to hinge the upper part of the door to the vertical rod C.

Then the door A is turned vertically, so as to stand or rest on its end, as shown in dotted lines in Fig. l, it maybe swung inward around the rod C, as the lower bent end of the quadrant-rod Eis secured near the bottom edge of the door in the same manner that the upper end of said rod is secured near the end of the door, and, as the combined pin and knuckle d el is secured at the lower corner of the door, the door may swing horizontally, whether it rests on its bottom edge, as shown in solid lines in Fig. l, or stands on its end, as shown in dotted lines in said ligure.

I clai1nl. The combination of the bent upright rod C, pivoted to the car, and door A, hinged to said rod by a two-way hinge, so that said door may swing open horizontally or turn around said hinge as a center in a vertical plane, subn stantially as specified.

2. The combination of bent upright rod C with door A, hinged to said rod by a two-way hinge at one corner of said door, and rod E, extending along the side of said door, from near its upper corner to its lower side, and embracing said rod Cv between the same and the door, substantially as specified.

3. The combination, with a grain-car door provided with a two-way hinge, of a rod, E, extending parallel with the side of the door, from near its upper corner to its lower side, substantially as specified.

4.. The combination of upright bent rod C, pivoted at each end to the car, with door A, provided with corner-piece or knuckle D, pin d, having knuckle d at its other end to re ceive said rod C, and adapted to slide freely up and down on the same, and casing B', provided with jamb or shoulder b and facing b, to furnish a guide for the door to slide up and down, substantially as specied.

5. The combination, with swinging door A, adapted also to turn around its hinge in a vertical plane, of bent pivoted rod C, and the two-way hinge securing said door to said rod, consisting of knuckle or corner-piece D, and combined pin and knuckle d d', substantially as specified.

6. The combination,with a grain-car door, of guides or means for sliding it upward, and hinges or means for swinging it around, of the pivoted door support or holder G, secured to the side of the car, substantially as specified.

7. The combination of the grain-car doorA with a rod, E, extending parallel to the side of the door across one of its corners, and pro- IOO vided with bent ends secured to said door, so that the bent ends of said rod may serve as a hinge on which the door may turn, Whether s"`aid door rests on its bottom edge, as shown 5 in heavy lines in Fig. 1, or stands on its end,

as shown in dotted lines in said gure, substantially as specied.
