Description

i lill@ l HINGE FOR SILO-DOORS.
Specification of Letters Patent.
Application filed September 9, 1915. Serial No. 49,789.
To all whom 'it may concern:
Be it known that I, CHARLES S. MiTCHELL, a citizen of the United States, residing at Grandview, in the county of Yakima and State of Washington, have invented certain new and useful Improvements in Hinges for Silo-Doors, of which the following is a specification.
My invention relates to an improvement in hinges, more particularly adapted for silo doors, and it consists in four straps and the two members of the hinge capable of turning therein, the upper strap on the door jamb having an incline, and the lower strap on the door a similar incline so that the gravity assists in closing the heavy door, and swinging it in place.
The invention further consists in certain novel features of construction, and combination of parts which will be hereinafter fully described and pointed out in the claims.
In the accompanying drawings: Figure 'l is a view of the door jamb showing the door opened inward into the silo; Figs. 2
and 3 are horizontal sectional views through the door, jamb and hinge showing the door both open and closed; and Fig. l is aI detached view in perspective of the hinge and straps, on an enlarged scale.
A is the door jamb, l is the door and'2 is a bar pivoted to the door for holding it fast and air-tight when closed by swinging it from a vertical to a horizontal position where its ends engage the sides of the jamb andbdraw the door outward against the door )am The hinge comprises two parts 3 and 4 Y preferably of wire of suitable size, the two horizontal arms 3 of member 3 terminating in eyes 5, and the horizontal arms 4 of member 4 in pintles 6, which enter the eyes 5, and in that way form the hinge connection. Straps 7 and 8 receive the vertical centers of the hinge members and are'em'- ployed as a means for fastening them to the inner face of the door jamb, and to one of the vertical braces 9 on the outer side of the door. The strap 8, 8 each have an incline 10 at an angle of say 45o upon which the upper arm of one member and the lower arm of the other hinge, ride down as the door is closed, thus getting the assistance of gravity in the closing of the heavy silo door. 'Ihe door in that way virtually closes itself after it is started.
More or less slight changes might be resorted to in the arrangement and form of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit Inyself to the exact construction herein set forth, but
I claim:
l. A silo hinge comprising two main members, the ends of which are extended at an angle to the main or center portions and hinged together, and straps embracing the central members and within which the latter turn, forming means by which the hinge is attached to the silo and part to be hinged thereto.
V2. A silo hinge composed of two members, the arms of which terminate in eyes and pintles, by which they are pivotally joined, and straps having oppositely extending inclines at the bearings, down which thearms of the hinge ride in the operation of the hinge.
8. 'Ihe combination of a hinge and door, the hinge comprising two members, the center portions of which are vertical and the ends in the form of arms, the arms of one member terminating in eyes and the other in pintles, and straps for connecting the vertical members to the door and door j amb, the outer edges of the uppermost and lowermost straps on the jamb and door having inclines at the bearings upon which the adjacent arm of the hinge turns and rides, whereby the assistance of gravity is utilized in the closing of the door.
In testimony whereof I aiiix my signature. CHARLES S. MITCHELL.
