UNITED STATES PATENT OEEICE.
JOHN PEARSON, OF PULLMAN, ILLINOIS.
GRAIN-CAR DOOR.`
SPECIFICATION forming part of Letters Patent No.468,894, dated February 16, 1892.
Application filed J une 22, 1891.`
and there temporarily secured, so as to be out ofthe way.
The objects of my invention are to provide reliable, simple, efficient, and otherwise improved means for preventing the escape of small grain between the door and car, to provide novel and improved means f or locking the door, to utilize means employed for locking'the door as a guard for preventing the escape of grain, to permit the door to be opened either inwardly or outwardly, as may be desired, and to provide certain novel and improved details, as hereinafter more fully set forth.
In the accompanying drawings, Figure l represents in elevation a portion of the inner side of a grain-car and door with the roof broken away and a portion of the roof-supports in section. Fig. 2 is a cross-section on line 2 2 in Fig. l. Fig. 3 represents in elevation a portion of the outer side of the car with its door closed and locked. Fig. 4 is a section on line 4 4 in Fig. 3 on a somewhat larger scale. Fig. 5 represents in perspective a portion of the door and means for locking it at one of its vertical ends, it being understood that like means for locking the door are also employed at its opposite end. Fig. G is a section on line 6 6 in Fig. 50u asomewhatlarger scale. Fig. 7 represents in perspective the combined guard and catch plate and shows its rear or inner side.
In said drawings, A indicates the car, and B the door, adapted for closing the lower portion of the doorway a. The door is provided at each of its two upper end corners with a horizontal pivot or pintle O, which is secured to the door and arranged to project from the end thereof. The side posts D of the doorway are provided with open bearings E, in which the pintles C rest when the door is down, as shown. In order to raise the door,
Serial No. 397,157. (No model.)
however, its pintles can be removed from said open bearings. l
To prevent loss or removal of the door from the car, the door-frame or similar portion of the car is provided with guide-rods F for eyes g on the ends of chains G, which are attached to the ends c of the pintles O. When, therefore, the door is raised, itsl pintles will free themselves from their respectively-allotted bearings, and the eyes g on the chains will slide up along the bars g, which are bent at their ends, so as to permit the main length of each bar to stand out from the timber to which it is secured. The open bearings E are secured to the inner vertical sides of the timbers D-that is to say, to the sides of the timb ers which are parallel with and in effect form portions of the inner longitudinal walls of the car-while the guide-rods F are secured to what may be termed the rear sides d of said timbers, of which their front sides el face the doorway.
At the upper portion of the door-frame I provide open bearings H, in which the door-pintles C can be placed after the door has been raised, and in addition to such upper open bearings I provide at the upper middle of the doorway catch I for engaging the lower edge of the door when the latter is brought into the position indicated in dotted lines in Fig. 2. Vhen, therefore, the door has been raised and its pintles have been caught by the open or hook-shaped upper bearings h, the door can be swung on said bearings so as to bring it into the position indicated in dotted lines and permit the swinging catch I to engage and hold the lower edge of the door.
As a means for locking the door in its down and closed position, I provide on each end of the door a pivoted catch K, and provide for each catch a catch-plate L, having a catchopening Z, in which the hook-shaped catch can engage. The plates L are also adapted to form guards for preventing the escape of grain between the vertical ends of the door and the vertical sides of the doorway, as best shown in Figs. 4 and 6, wherein one of these combined catch and guard plates is shown opposite a crack b between the door and side of the doorway. Each combined catch and guard plate is arranged so that when it is engaged by its allotted catch it must be in posi- IOO tion to close a crack between the door and side of the doorway. While the combined catch i catch and guard plate is arranged to have a certain extent of lateral play parallel with the plane of the side of the car, and hence,
after the catches have been freed from the combined catch and guard plates, the latter l 6, and provided o'n its rear or inner side with bearings l for bolts M, which extendthrough openings l2 in said bearings and fasten in the 'sides' of the doorway. The openings Z2 are sufficiently large to permit the bearings to slide upon them, andthe sides of the doorwa'y' are provided with mo'rt'ises d', in which thevl bearings Z can be received when the combined catch and guard plates are moved in directions to clear the doorway. The sides of the doorway are also recessed, asv at cli-,to .receive portions of the' combined catcharid guard plates' When the latter are in position to be engaged b'y their allotted catches, and also to' receive said plates when they are moved iii directions toA clear the doorway. By such arrangement these combined catch and guard plates also serve to lock and brace the door against the pressure of grain against its inner side, it being seen that When, for example, the combined catch and guard plate is in the position shown in Fig. 6, any disposition on'the part of the door to press outwardly will be taken up by said plate and resisted by the side wall d3 of the recess against which the plate Will abut. These side walls or abutments d3 serve, therefore, tol brace the door from top to bottom against internal pressure.
What I claim as my invention is-' l.V The combination, in a car, for the purpose set forth, of a swinging door, an adjustable combined guard, catch, and abutment plate movable into and out of position for opposing the outward swing of the door and checking' the escapeA of grain between the closeddoor and side of the doorway, and a catch carried bythe door and arranged for engaging and holding said plate in position to serve as a guard andabutnen-t and at the same time lockand hold the door against inward swing, substantially as described.
2. The combination, with a carhav'ing a doorway a and provided witlr pintlebear ings E, of the door provided with pintles C, the movable guard-plates L, eachadapted to form a combined catch and guard plate, and catches on the door `arra'n'ged to engagev and lock said plates in position to prevent theescape of grain between the door and sides d of thedoorway, snbstantially as set forth.l
