W. H. HARDIMAN GRAIN DOO R Filed April 4, 1922 2 Sheets-Sheet 2 INVENTOR ATTO R N EY Patented Dec. 16, 1924.
UNITED STATES PATENT OFFICE.
WINTON H. HARDIMAN, OF ST. LOUIS, MISSOURI, ASSIGNOR TO H. P. MURMANN, OF
ST. LOUIS,
MISSOURI.
Application filed April 4,
Z '0 all to 710m it may concern:
Be it known that I, IVINTON H. HARDI- irAN, a citizen of the United States, residing at St. Louis, in the county of St. Louis and State of Missouri, have invented new and useful Improvements in Grain Doors, of which the following is a specification.
This invention relates to a grain door construction and has for its primary object a construction whereby the pressure of grain within a car door may be properly taken care of.
A feature of the invention is the novel substantial manner of constructing the door so that same will not bulge thereby enabling the door to coact with other elements in a manner to prevent grain from being subject to climatic conditions.
Besides the above my invention is distinguished in the novel construction of lock.
With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein:
Fig. 1 is a front elevation of a door constructed in accordance with my invention.
Fig. 2 is a vertical sectional view.
Fig. 3 is a sectional view on the line 3-3 of Fig. 1.
Fig. 1 is a sectional view on the line 14 of Fig. 2.
Fig. 5 is a sectional view on the line 55 of Fig. 2.
Fig. 6 is a sectional view on the line 66 of Fig. 1.
Fig. 7 is a sectional view 011 the line 77 of Fig. 1.
Fig. 8 is a sectional view on the line 8-8 of Fig. 2.
Fig. 9 is a detailed view of a portion of the lock. n
Again referring to the drawing illustrating one of the many constructions of my invention the numeral 1 designates a door constructed of sections 2 and 3 each having tongue and groove connection with each other as indicated at 4:. These sections are rigidly bound together by the straps 5 bolted together and to the door by the bolts 6. The handle 7 enables the door to be slid along the track 8 upon which ride the wheels 9 of the door. The upright 10 is provided with a through passage 1922. Serial No. 549,553.
11 for allowing the door to move there through and the upright 12 is formed with a depression 13 for receiving the vertical edge portion 14; of the door.
The edge portion 14; is provided with a recess 15. A plate 16 is bolted to the door and has an L-shaped extension 17 arranged in the recess and having pivotal connection 18 with the hasp 19. It will be noted that the recess is of a size to allow the hasp to be readily folded therein for the purpose of protecting the hasp and besides accommodate better movement of the door into open position and also allow better access through the door opening. The hasp 19 is provided adjacent one end with a notch 20 for the reception of the short limb 21 of an L-shaped keeper 22. This L-shaped keeper 22 is bolted to the interior of a casing 23 that is closed by a door 24. A seal such as now used in sealing freight cars 29 is provided for sealing the door by passing it through the hole in the hasp and around the keeper.
For the purpose of preventing accidental disengagement between the hasp and keeper I provide a retainer 26 which is in the form of a pivoted hook having a cam shaped extremity 27 for allowing the hasp toreadily pass thereunder. A finger piece 28 is formed on the retainer 26 to permit manual releasing movement of the retainer.
For the purpose of making the door waterproof I provide weather strips 31. The weather strip at the lower end of the door is hinged for downward and outward movement and is held in place by the clip 33 that is pivotally connected to the door as indicated at 34.
From the foregoing description taken in connection with the accompanying drawing it will be apparent that I provide a grain door construction of a very rigid design and which will stand all the rough usage to which a door of this character is subject.
The novel construction of locking means enables the door to be rigidly locked against movement and makes it necessary for unauthorized persons to break two seals.
It will also be noted that the various parts are fully protected from the weather which will greatly prolong the life thereof.
It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in different relations and therefore, I do not desireto be limitedin anymannerexcept as set forth in the claims hereunto appended.
Having thus described my invention what Iclaim is:
1. In a grain door, a pair of uprightszone of which is provided with a vertical slot, a door mounted for sliding movement through the slot in said upright, the other upright opposite to the slotted upright being provided with a recess for receiving one edge of the s'lidable door, a bar rigidly connected to the door, a hasp 'pivotally connectedto said bar, saiddoor being recessed to permit/the hasp to be folded intothe recess and flush with the edge of the door, akeeper remote from said uprights and adapted to engage saidhasp, and a gravity operated pawl engaging-the hasptoiorce it into locking engagement with said keeper.
2. In a'grain-door, a'pair of uprights one of which is provided with a vertical slot, a doorimounted ifor-sliding movement through the slot in said upright, the other uprightopposite -to the slotted upright being provided with a recess for receiving one edge of the slidable door, a bar rigidly connected .tto rthe door, a hasp pivotally connected to said bar, said door being recessed to permit the' hasp to be "folded into the recess and flush with the edge of the door, a keeper remote from said uprights'and adapted to engage said hasp, a gravity operated pawl engaging'the hasp-to force it into locking engagement with said keeper, and weather strips mounted about the edges of the door, the weather strip at the bottom of the door beinghingedly supported.
In testimony whereofI affix my signature.
WVINTON H. HARDIMAN.
