D003, AND OPERATING EEEAIIS THEREFOR.
Application filed August 27, 1924.
This invention relates to doors capable of use in connection with gram cars, wagons and the like.
Briefly stated, an important object of this invention is to provide a door having simple means whereby the same may be inovet to and held in a desires position against the pressure of the grain or the like within the car or other carrier in. connection with which the door is employed.
A further object is to provide a door and operating means therefor which. may be applied to a grain car or the like either during the course of manufacture of the car. or at any time thereafter without the exercise of unusual skill.
Other objects and advantages will be apparent during the course 01. the following description.
In the accompanying drawings forming; a part of this application, and in which like numerals are employed to designate like parts tl'iroughout the same,
Fig. 1 is a perspective of the improved door and operating means applied.
Fig. 2 isa horizontal sectional View taken on, line 2-2 of Fig. 1.
Fig. 3 is a vertical transverse sectional view through the door and operating means.
Fig. 4t is a group perspective of the invention.
In the drawing, the numeral 5 designates a wall of any type, and which for the purpose of this specification, may be assumed to be one side wall of a grain car. It is, however, understood that the invention is capable of use in connection with wagons, coal bins and the like.
Fig. 1 illustrates that a frame 6 may be securely connected to the wall 5 by means of attaching arms 7. the outer portions of which are extended angularly to provide lugs 8 which engage the outer surface of the frame 6, and which are securely connected thereto by fastening devices 9 in the nature of screws or the like. The inner portions of the arms 7 may be secured in or extended entirely through the wall 5 so that the same are firmly anchored to the wall. This secures the frame 6 at one side of the opening 10 so that the door 11, which is sli'dably carried by the frame may be moved to closed Serial No. 73,4-9'?.
position to control the movement of grain or the like through the opening.
"he frame 6 is provided at its lo "er portion with depending guide strips 12 and 14;. which define channels to slidahly receive the edge portions of the door to guide the door in its vertical movement, and to secure ly hold the door in position when it is closed. It will be seen that the upper portion of the frame 6 is closed so as to form a compartment to receive the maj or portion of the door when. the latter is open.
The door 11 has its lower portion, pr vided with an outwardly projecting; bri cket to which a vertically arranged rack 21 is permanently and rigidly com'iec'ed. Fig. 4 plainly illustrates that the iclret 20 spaces the rack 21 outwardly from the door so that the door is positioned within the casing, while the rack is positioned exteriorly of the casing and may move through the guide 22.
The guide 22 is carried by the intermediate portion of the casing and receives a gear 23 having an outwardly extendingshaft 2% to which a crank 25 is connected. A suitable f'astening device in the nature of a nut 27 is employed to securely connect the crank 25 to the shaft 2 1. As the gear 23 is constantly in mesh with the rack 21, the turning of the crank 25 will result in the vertical movement of the rack for adjusting the door to the desired position.
The outer portion of the crank 25 is provided with a pin 30 upon which a handle til is slidably mounted, and the inner end of the handle engages the looped portion 32 of a lever 33, the lever being engaged with a fnlcrunied member so that it may be rooted thereon. The inner end of the lever 33 is formed with a bend which defines a locking dog adapted to be received in one end by a series of radial notches 36 in a boss 37 formed on the outer side of the guide 22. The dog is urged into one of the notches 36 by a leaf spring 39 carried by the crank 25 and urged into contact with the looped outer portion 32 of the lever. If it is desired to turn the handle, it is merely necessary. to push inwardly on the handle against the tension of the leaf spring 39, and then turn the crank. Of course when an inward pressure is exerted on the handle 39, the lever 99 is swung on its fulcrum to release the locking dog 35. The shaft 24: which carries the gear 23 may be carried by a base plate a0 arranged inwardly of the guide 22 and secured to the casing by fastening devices 42 of any nature.
lVith reference to the foregoing description, it will be seen that this invention is es 'sential in the nature of an attachment which 'n'iav be applied to 'a grain car door, a wagon,
a silo, a coal bin, or in fact any place where a vertically slidable door is useful. The door may be provided with a locking means e5 of any type.
Fig. 4 illustrates that the lower end of the door is bevelled on opposite sides to provide an edge 46 which may cut through the grain or the like to render the closing of the door easy.
Fig. 5 illustrates that the guide 60 may be provided with a train of gears 61, one of which is in mesh with the rack 63.
While I have described and illustrated a preferred embodiment of my invention in accordance with the patent statutes, yet it will be understood that various changes and modifications may be made therein, as will readily occur to those skilled in the art, without, however, departing from the spirit of the invention, the scope of which is delined by the following claims.
Having thus described the invention, what is claimed is:
- 1. In combination with a door and door frame, lifting means comprising a shaftjournaled upon the frame, means connecting the shaft with the door, a notched boss mounted upon the frame and surrounding the shaft, an arm mounted upon the shaft,
a pin carried by the arm, a handle grip slidably mounted upon the pin, a fulcrum member carried by the arm, a lever pivoted to the fulcrum member and provided at one end with an angularly disposed dog adapted to engage the notches of said boss, the opposite end of said lever contacting with the inner end of the handle grip, and yieldable means interposed between said arm and said lever for normally holding the dog of said lever in engagement with one of the notches of said boss.
In combination with a door movably mounted in a frame, a lifting means comprising a guide mounted upon the frame, a rack bar attached to the door and passing through the guide, a train of gear wheels journaled in the guide, the teeth of one of the gear wheels meshing with the teeth of the rack bar, a shaft carrying one of the gear wheels and journaled in the guide, an arm mounted upon the shaft, a pin carried by the arm, a handle grip slidably mounted upon the pin, a fulcrum member carried by the arm, a lever pivoted upon the fulcrum member and having an eye which receives the pin a d which bears against the end of the handle grip, a spring engaging the fulcrum member and the arm and having an opening whiih receives the pin, said spring bearing against the eye of the lever, the guide being provided at its side with a boss having notches, said lever being provided with an angularly disposed dog which passes through the arm and engages in the notches of the boss.
In testimony whereof I afiix my signature.
RICHARD W. iEEVES.
