GRAIN-DOOR FOR CARS.

:SPECIFIUATION forming part of Letters Patent No. 688,822, dated December 17, 1901.

Applieationfiled June 14,1901. $eria1 No. 64,565- (No model.)

To aZZ whom, it may concern.-

Be it known that I, LOUIS BEESE, a citizen of the United States, residing at West Supetures and combinations, as hereinafter shown and described, and specifically pointed out in the claims.

In the drawings illustrative of the invention, Figure 1 is a side elevation, foreshortened, of a portion of the side of a car, including the doorway-opening, with one of my improved grain-doors arranged therein. Fig. 2 is a vertical section on the line 2 2 of Fig.

1. Fig. 3 is a longitudinal sectional elevation of the car, illustrating the construction of theinner side of the grain-door. Fig. 4 is a transverse section on the line 4 4 of Fig. 3. Fig. 5 is a sectional plan View of the device on the line 5 5 of Fig. 1, and Fig. 6 is a similar view on the line 6 6 of Fig. 1.

Thisim proved grain-door may be arranged I in connection with any form of ear, and in the drawings 5 represents a section of the side .of a car; 6, the sill; 7, the floor; 8, the cap or lintel timber, and 9 and 10 the jambs or side posts of the doorway of the ordinary con struction.

11 is the grain-door, which fits between the jambs or side posts 9 and 10 and rests when in use by its lower edge upon the sill 6 and ttloor 7.

12 12 are two suspension-bars connected by hinged joints 14: 15 to the head timber 8 and with their lower ends attached to the rear or inner side of the door 11 by keepers 1.6, 17, 18, and 19, fast to the door, so that the door is vertically slidable upon the bars.

The lower extremities of the bars 12 and 13' are turned outward, as at and 21, to prevent the door from slipping off from the bars,

vated position on the bars and enable it to.

be folded up into the top of the car and be fastened in that position by any suitable means in the ordinary manner of doors of this class.

24 25 are small clips attached to the inner lower sides of the side posts 9 10 to assist in supporting the door 11 and to form guides to prevent the lower side from moving inward when being placed in position.

Attached centrally to the outer side of the door 11 are two disks or plates 26 27, both centrally pivoted upon the door by a bolt 28.

29 is an arm passing in a substantially vertical line across the outer disk 27 and attached rigidly thereto by bolts or rivets 30 31,

the central bolt 28 also passing through this arm.

point far enough downward to be within reach of a person from the ground, so that the arm,

hinged hasp 32, adapted to engage a staple 33 on the door, so that a lock 34 maybe applied thereto.

35 36 are two vertical plates, one on each side of the outer face of the door near the vertical edges and seen red to the doorby bolts 37, fitting through slots 38 in the plates, so that the plates will have considerable horizontal movement. This horizontal movement of the plates 35 36 will be sufficient to permit the outer edges of the plates to project some distance beyond the edges of the door and enter vertical recesses 39 in the posts 9 10 when the plates are distended, as shown more clearly in Figs. 4 and 5. These plates thus close the gap which would otherwise occur I03 between the door and the posts 910 and form grain-tight joints bet-ween the door and its jambs or side timbers.

Reinforcing or guard strips 40 will be ar- By this sim- 55 The lower end of the arm 29 extends to a ranged in the recesses 39 and upon the inner face of the side posts, as shown in Fig. 5, to form wear-plates for the plates 35 3G to prevent wear upon the wooden side timbers.

41 42 are U -shaped bars connected by their ends at 43 44 to the plates 36 and also pivotally secured at 45 46 between the plates 26 27, as shown, the bars beingheld in place by keepers 47 48.

The ends'43 44 of they bars 41 42 project beyond the edges of the plates 35 36, as shown, and are wedge-shaped orinclined on the outer faces, so that when the arm 29, together with 'its attached disks 26 27, are moved to throw portant purposesviz.,they receive and bear the strain exerted upon the door and largely I relieve the plates 36 from strains, leaving them free to perform their legitimate function' of keeping the gap between the vertical edges of the door and the jambs closed and also servingas reinforcing-st rips to the plates to support them from the outside and relieving the bolts from end-th rust strains. These are important advantages and add materially to the efficiency of the door. This construction also ettectually prevents any tendency of the plates 35 36 to bind in the recess.

47 is a bar pivoted at its upper end at 48 in the plates and passing downward through akeeper 49 on the door 11 and adapted when depressed to enter a seat 50 in the sill 7, and thus serve as a support to the lower edge of the door.

It will be readily understood that when the disks 26 27 are turned by the arm 29 the lower end of the bar 47 will be thrown downward into its seat 50 at the same time thatthe arms 41 42, with the plates 35 36, are thrown outward, as before stated. The whole action will thus be accomplished byone movement of the one arm 29.

This for-ms a very sim ple and efficient graindoor perfectly adapted to the work required and capable of being applied to any of the different makes of cars now in use.

What I claim as new is- 1. In a device of the class described, adoorway-opening having vertically slotted and recessed j ambs, a grain-door fitting within said opening, vertical plates arranged on the outside of the door and near the vertical edges of the same, guiding-bolts 37 carried by the door and adapted to slotted openings in said plate, a pair of spaced disks 26, 27, centrally pivoted on the outside of the door, U-shap'ed locking-bars pivoted between said disks and having their outer ends rigidly secured to the plates and projecting beyond the outer edges thereof, an operating-lever 29 secured to said disk and provided at its lower end with a handle, a locking-hasp hinged to the upper end of said lever and adapted for engagement with a locking-staple on the door, a vertical bar 47 pivoted between the disks and adapted to a recess in the door-sill, and a keeper for guiding said bar, substantially as specified.

2. In a device of the class described, adoorway-opening,suspension-bars hinged by their upper ends to the lintel of said doorway and with lateral projections on their lower ends, a grain-door, keepers upon said door and engaging said suspension-bars, whereby said door is slidably disposed upon said bars, and catches upon said door adapted to engage said projections when said door is elevated, substantially as described.

3. In adevice of the class described, adoorway-opening, suspension-bars hinged at their upper ends to a support above the doorway and provided at their lower ends with lateral extensions or projections 21, a grain-door, keepers secured to said grain-door and formingguides for the suspension-bars,and hinged catches 22 and 23 carried by the door and having lower foot portions adapted to engage said projections, and operating-handle portions provided at the upper ends of said catches, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in
