GRAIN-CAR DOOR.

SPIEGIFICATIGNforming part of Letters Patent No. '745.259, dated November 24, 1903. Application filed May 25| 1903 Serial No. 158.710 (No model.)

To all whom it 'may concern:

Be it known that I, ANDREW G. STEiNBREN- NER, a citizen of the United States, residing in'the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Grain-Oar Doors, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, forming part of this speci- Iication.

My invention relates to that character of grain-car doors in which openings are provided for the exit of grain from the interior of the car previous to opening the door completely and also an limprovement in the guideway face-stri ps against which the guide-studs of the door operate.

My invention consists in features of nov elty hereinafter fully described, and pointed out in the claims.

Figure ,I is a front elevation of a grain-car door constructed in accordance with my improvement. Fig. II is a vertical section taken on line II II, I. Fig. III is an inside elevation of one of the door-posts of a graincar with the guideway face-strips applied thereto and a fragment of the4 grain-door. Fig. IV is a horizontal section taken on line IV IV, Fig. II. Fig. V is ahorizontal section taken on line V V, Fig. II, through the door and one of the gate guide members. Fig. VI is a perspective view of one of the gate guide members.

1 designates the posts of a grain-car doorway. These posts are rabbeted, as seen in Figs. II and IV, the rabbets therein extending to the inside faces of the posts within the car. The production of the rabbets referred to provides for guideways 2 between a forward guide strip 3 having flanges et and inner guideway face-strips 5 having flanges 6, disposed opposite to the flanges 4 of the strips but separated therefrom, as seen in Figs. II and IV. The guideway face-strips 5 are provided with series of ears 7, that project beyond the rabbeted portions of the doorposts and through means of which said facestrips are secured to the posts by screws S passing through said parts. At the upper end of each guideway face-strip is a socket 9. These guideway face-strips are subjected to considerable strain by the guide-studs of a grain-car door, and unless additional means for their retention to the doorway-posts other than bolts or screws is provided they frequently become loosened as a'result of the strain to which they are subjected. For the purpose of strengthening their connection to the posts I provide studs l0, projecting from their rear faces into recesses in the posts, as seen in Figs. III and IV. These studs affoi d resistance to the lateral movement cfs-aid face-plates and relieve the fastenings coni nectin g them to lhe posts of strain, so that the attachment of the strips remains secure.

il designates a dool` positioned at the inside of the car against the posts l and slidably connected to said posts by studs l2, provided with heads 18, (see Fig. IV,) which operatein the guidfeways 2 between the guideway-strips 3 and 5. These studs l2 are designed to travel upwardly in said guideways in the raising of the door 1l, so that the studs may be passed into the sockets 9 of the guideway face-strips 5 when the door is suspended beneath the roof of the carin the usual manner. It is during this 'movement of the door and the travel of the guide-studs that said guideway face-strips are subjected to the strain hereinbefore referred to.

In the door l1 are gateways LL through which the grain within the car equipped with my door is first discharged in emptying the car. These gateways are controlled by gates 15, held in the manner to be presently described. The gates 15 are pliable and resilif ent, being of sheet metal, and each gate is provided with a handle 16, by which the gate may be engaged to move'it to and from said gateway.

17 designates gate guide members secured to the door l1 at the sides of the gateways therein by bolts or screws 18, that pass therethrough. (See Fig. I.) Each of the gate guide members is composed of a side wall 19, bearing a curved outer llange 20, extending ap- IOC the side wall 19 of each gate guide member is a lug 22, that occupies a position between the upper end of' the flange 2l and the upper extremity of the curved flange 20, as seen most clearly in Fig. VI. l

23 designates ears projecting inwardly from the iiange 2l to receive bolts 24. (See Figs. II and VI.) These ears project through the gateways 14 and aresecured to the uprights ll of the door ll to hold the lower ends of the gate-guide members firmly to the door.

By the use of a gate of the form described and guide members having flanges shaped and positioned as set forth I provide a construction by which the gates are securely maintained in either closed or open positions by reason of the frictional contact between the gate and guide members. This is due to the gates being pliable and resilient and the outer flanges of the guide-boxes being curved, as described, so that the gate will be iiexed at all times to produce fricticnal contact between it and the flanges 2O and 2l and lugs 22 of said guide members, as seen in Fig. II.

I claim as my inventionl. The combination with a graincar door having a gateway, of guide members having curved flanges and secured to said door, and

a pliable resilient sheet-metal gate slidably positioned in said guide members for frictional contact against said curved fianges when the gate is shifted in said members, substantially as set forth. l

2. The combination with a grain-car door having a gateway, guide members secured to said door and each having a straight flange and a curved flange, and a pliable resilient sheet-metal gate slidably positioned between said flanges for frictional contact therewith7 substantially as set forth.

3. The combination with a grain-car door having a gateway, of guide members xed to said door and each having a curved flange and a straight ange extending a portion of the length of said curved flange, and a lug positioned between the termination of said straight flange and the far end of said curved iiange, and a pliable resilient gate slidably positioned between said flanges, and between said curved flange and said lug to bind bctween said parts when the gate is shifted in said member, substantially as set forth.
