SPECIFICATION forming part of Letters Patent N0. 788,580, dated May 2, 1905.
Application filed October 8, 1904. Serial No. 227,702.
To all/ w/tom it may concern:
Be it known that], TVILLIAIWI J. CooKLIN, a citizen of the United States, and a resident of Rising City, in the county of Butler, in the State of Nebraska, have invented certain new and useful Improvements in Grain-Doors for Freight-Cars, of which the following is a description.
The object of my invention is to provide a door adapted to form agrain-tightunion with the door-frame, to be constructed to be securely locked, readily operated, and be arranged to be swung out of position when not in use as a grain-door.
In the accompanying drawings I have shown in Figure 1 afront view, with portions broken away, a grain-door embodying my invention. Fig. 2 shows an edge view disclosing the manner in which the angle-flanges are bent. Fig. 3 discloses a horizontal sectional view of one of the keepers as used in my invention, while Fig. 1 discloses the method of securing one of the angle-flanges to its keeper.
It is well known that grain when loaded in bulk in grain-cars has a tendency to force the grain-dooroutward, the pressure of the grain causing the door to bind upon the frame. This results in forcing the door into frictional contact with the door-post, and it is exceedingly difiicult to open the grain-door with the weight of the mass of grain binding upon the same.
In my construction the door is arranged to receive the pressure its full length upon the sliding-plates, which plates work upon the door-post. The door, further, upon the outside is provided with a central and two side shoulders, below which the end of a crowbar or other instrument may be placed in raising the gate or door in unloading the car.
In carrying out the aim of my invention I provide a grain-door composed of a plurality of members, as shown at a. These members are in the form of planks horizontally disposed and securely fastened and reinforced upon the outside by the two vertical members 1 and 1, which terminate a suitable distance above the lower edge of the lower door member a, as is shown in Fig. 1, to provide the terminal shoulders 02. Centrally I provide the stop-block 2, which is notched to receive the V-shaped ends of the reinforcingstrips 3 3, which above are secured to the vertical members 1, which members 1 project above beyond the upper edge of the uppermost door member (5.
The stop-block 2 is bound by means of the iron reinforcing-strip 4:, which forms a shoe and also secures the stop-block 2 to the reinforcing-strips 3, as shown in the drawings.
It should be remembered that the door members a rest against the inner faces of the doorposts 5 5, so that the pressure upon the door is directly upon the d0or-frame.
My grain-door is reinforced along the vertical edges, as is shown in Fig. 2, by means of the angle-flanges A. The bottom of the gate is reinforced by a U-shaped metallic reinforcement 7 to forma metallic binding. These flanges A have a tendency to wear smooth, so that they readily slide upon the wooden surface of the door-posts. By means of the vertical flanges A and the bottom reinforcement 7 a very strong construction is provided. These vertical flanges A are slotted at suitable points to permit the heads 9 extending through the same, which members form part of the locking-levers 10, each being held upon a pivotpin o, two such locking-levers being used, as shown in-Fig. 1, and these pins o pass through and are supported by means of the vertica members 1 l.
Each door-post 5 at a suitable point is slotted and provided with a metallic reinforcement 12, forming a pocket into which the head 9 extends, as is shown in cross-sectionin Fig. 1. By virtue of the long levers 10 these lockingheads 9 are normally forced beyond the graindoor when said grain-door is in a vertical position, as shown in Fig. 1.
Secured within the top door-frame member 6 are the guide-rods A, which below curve inward into the door-frame posts 5, as shown, and slidably held upon these guide-rods A are the U-shaped keepers 13, as shown in Fig. 3, and to these keepers are pivotally secured, by means of the pins 0, the ends 14, forming securing members of the flanges 15, forming the outwardly-extending portions of the flanges A, as shown in Figs. 1, 2, and 4:. As shown in Fig. 3, these keepers are U-shaped and encompass the guide-rods A, so that they freely slide upon the same, the door-posts 5 being slightly grooved, as is shown at 12 in Fig. 3, so that these keepers may slide as near as possible to the door-posts and which also prevents the guide-rods A from projecting very far from the door-posts. As shown in Fig. 4:, the ends 14 are secured to the portions 15 of the flange A by means of rivets p.
Now in opening this grain-door it was simply necessary to place some prying instrument below the lower ends of the stop-block 2 and the members 1 to raise the door, which when not in use is carried upward and supported upon the bar B, held by the pin 0,.
secured to the upper member 6 of the doorframe. The bar B is pivotally held and in Fig. 1 is shown as extending inward. In order to support the grain-door, this bar B would be turned upon the pin 0 to bring the bar in vertical alinement and between the door-posts, so that the grain-door could be shoved forward as far as possible and then held in a horizontal position, when the bar B would be swung under the same to form a simple bracket. Any suitable support, however, may beused to hold this grain-door upward and out of position when the same is not in use. From this it will be seen that the peculiarly-shaped flanges A are used to reinforce the grain-door, providing the same with a metal edge, the extending webs 15 providing stops to prevent the lateral displacement of the grain-door, while at the same time forming guides for the locking-lever heads 9.
This gate is simple of construction and is readily operated and forms both a cheap and lasting door. 7
The stop-blockQ has its lower end metal-reinforced to prolong its life, as this is a point zlvhere the greatest straincomes in opening the oor.
It is of course understood that this door is adapted to be used in connection with any style of a car-door.
Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-
In a device of the character described, the combination with a grain-door, of two vertical door-reinforcing members of a length less than the width of the door to provide shoulders below, a stop-block secured centrally to the grain-door, two angle-flanges one secured to each vertical edge of the grain-door one edge of each angle-flange extending outward in the form of a webeach of said webs being slotted, two headed locking-levers secured to the grain-door, said heads extending through the slots within said webs and being adapted to work within a pocket, of a suitable doorpost, securing members fastened to each of said flanges, a U-shaped keeper pivotally fastened to each securing member, and a guiderod adapted to be engaged by each keeper said guide-rod being suitably secured as set forth. In testimony whereof I afiix my signature in presence of two witnesses.
