GRAIN-DOOR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 737,018, dated August 25, 1903. Application filed December 23, 19Q2. Serial No. 136,376. (No model.)

To all whom it II'I/(I/Z/ con/corn: 4

Be it known that we, HERMAN PRIES and JOHNWVJ/IEYERmitizens of the United States, and residents of Michigan City, county of La Porto and State of Indiana, have invented certain new anduseful Improvements in Grain- Doors for Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

rangement and combination of parts herein-' after particularly described, specifically designated in the claims, and illustrated in the accompanying drawings, in which- Figure 1 is a view of the door from the in- Fig. 2 is a View of the outer side of the door removed from the car. Fig. 3 is a section on the line now of Fig. 1. Fig. 4 is a section on the line y y of Fig. 1, and Fig. 5 is a section on the line of Fig. 2.

In the drawings, Figs. 1 and *l,there is shown a portion of the side of a car, 10 indicating the roof, 11 the floor, and 12 the vertical side posts of the discharging opening or doorway thereof. The usual sliding door adapted to close the door-opening from the outside is not shown. Located adjacent the inner face of each of the posts 12 is a metal guide-strip 13, which is secured to a vertical rib let,provided in the construction illustrated, as shown in Fig. 3, by cutting on the inner face of the post parallel recesses or grooves 15, the edges of the plate 13 projecting laterally beyond the rib and over the said grooves. It will be obvious that the strip 13 and the rib 1e may be integral, although this is immaterial. The grain-door 16, normally closing the lower end of the discharge-opening of the car, is somewhat wider than the said opening, its ends extending, as shown in Figs. land 3, somewhat past the adjacent inner edges of the hinge members 17 are secured by clips 20,

bolted to the door and embracing lateral extensions 21of'the hinge-plates and secured by bolts 22. When the door is mounted in position, the fingers 18 of the hinge members are located at opposite sides of the strips 13, and the lugs 19 extend and slide, as shown in Fig. 3, in the grooves 15 of the door-posts be hind the guide-strip and engage the projecting lateral edges or flanges of the latter, the said lugs being slightly offset outwardly from the outer faces of the plates 17 in order that they may extend behind the strips 13. In'the hinges shown the plate 17 of each has on its outer face at the opposite edges flanges 18, and the fingers 18 are a continuation of these flanges.

the hinges to slide easily on the strips 13. By this arrangement tilting and consequent binding of the hinges on the guide-strips are avoided.

The grooves 15 in-the posts 12 need be only as long as the range of the sliding movement of the door, as shown in Fig. 1; but the strips 13 are preferably extended the length of the door-posts, the purpose being to prevent the driving of nailsinto the posts adjacent to the ends or upper corners of the door, which is sometimes done, though quite-unnecessarily, in order to hold the door against vibration and rattling to prevent shaking out and spilling the grainand results in injury to the car.

Such flanges and the fingers' are spaced apart just sufficiently to permit The strips 13 at the upper end are provided the same when it is swung inwardly and secured to the top of the car by a latch or catch in the usual manner. The lower faces of the hooks 26 are inclined parallel with the lower inclined ends of the loops 23, and the upper ends of the grooves 15 terminate in the space between the hook and the bottom of the loop. In consequence of this arrangement the lower outer faces of the hooks deflect the pivot-lugs or pintles 19 of the hinges inwardly, which are then directed outwardly and into engagement with the hooks 26 by the curved portions 24 of the guide-strips l3.

Secured near the bottom of the outer face of the door 16 and adjacent the edges of the same are guide plates or blocks 27, and these are secured apart a distance slightly less than the width between the door-posts to permit of some lateral play of the door in order to compensate for irregularities in the said posts due to warping or other causes, and for the same reason the extensions 21 of the hinges are provided with horizontal slots 28, (shown in dotted lines, Fig. 2,) through which the securing-bolts 22 pass, permitting lateral play of the door on the hinges, the extensions 21 being loosely held by the clips 20.

In order to relieve the pressure of the grain against the main door 16, so as to permit of the elevation of the latter, an opening is provided near the bottom of same and closed by a panel-door hinged, as at 30, at its upper edge to the door 16.. Owing to the excessive pressure upon this door, difficulty has heretofore been encountered in releasing the same. To overcome this difliculty, there is provided a pair of latches 31, pivoted to the door 16 below the door 29, and which latches are adapted to engage the lower edge of the panel-door or, preferably, beveled plates 32, which plates may, as shown in Fig. 2, be extensions of the hinges 30. The latches 31 have extensions or arms 33, which in order to provide for simultaneous movement of the same are pivotally connected by a rod or bar 34, which may have a hook or eye 35 for the engagement of an operating-tool. The latches 31 are held against movement by dogs 36, pivoted adjacent opposite sides of the same and engaging the extensions 33 thereof, and when it is designed to release the panel-door these dogs are thrown or tilted outwardly. In order to effectually lock the latches 31 and also to prevent the dogs from slipping past them, the engaging faces of the dogs 36 are straight, as are also the faces of the extensions 33, engaged thereby; but these dogs may be readily thrown out of action, the lower ends of the engaging faces thereof being curved inwardly toward the pivots of the same, as seen in Fig. 2, so as to clear the extensions when the dogs are raised.

The panel-door is provided with strips 37 at the edges of the same to close all interstices and prevent leakage of the grain when the panel-door is closed.

The usual auxiliary door 38 may be provided and loosely hinged, as at 39, to the upper edge of the door 16 and designed to swing upwardly to close the opening above-the latter. When the door 16 is to be elevated and swung open, the auxiliary door may be folded against the same, as shown in Fig. 4, so as not to interfere with the movement of the door 16 when it is hung up to the roof of the car.

We claim as our invention- 1. In combination, a pair of guide-strips, a door, sliding members secured to the door and having prolonged flanges embracing both edges of each strip, and. extensions projecting inwardly from such flanges back of the strips.
