FASTENING MEANS FOR SILO-DOORS.
Qpecification of Letters Patent. Patent-ed Mar. 2 2, 191M Application filed July 12, 1909. Serial No. 507,222.
To all whom it may concern.
Be it known that we, Lnonnno MASON CLARK, a citizen of the United States, residing at Moniton, in the county of Appanooseand State of Iowa, and WERTER S. FARRAR, a citizen of the Uriited States, residing at Burlington, county of Des Moines, State of Iowa, haveinvented certain new and useful Improvements in Fastening Means for Silo-Doors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in fastening means for silo doors, and has for its object to provide a fastening means, whereby an air-tight fit may be effected between the door and its frame. i
A further object is to provide simple an efiicient manually operable fastening means for the door, and a further object is to provide an improved method of hingedly mounting the door in position.
With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts,as will be more fully described and particularly pointedout inthe appended claims.
In the accompanying drawings: Figure 1, is a front elevation of a silo door and a portion of the frame illustrating the application of our improved fastening means. Fig. 2 is a horizontal section taken through the locking plates and operating bars, and Fig. 3, is a similar view with the fastening means .in releasing position and the door swung inwardly to disclose the door opening. I
Referring to the drawings for a more particular description of the invention, 1, indicates the frame, consisting of the upright and cross pieces 2 and 3, respectively, the inner side edges of the uprig ts being reinforced and project by metallicstrips 4, and the upper and lower ends of the side pieces being connected by the horizontal bars 5. The silo door 6, has itsedge recessed the entire way around leaving the flange -7,- which fits in the recessed inner faces of the side and cross pieces of the frame. The door is hingedly mounted in position by a pair of vertically spaced horizontal approximately U-shaped han er bars 8, the outer ends of which are hingedly con nected with the forked attaching plates 9,
which are bolted to one of the side pieces of the frame, while the inner ends of said bars are hingedly connected to corresponding attaching plates 10, which are secured to tile door. By this means, the door may be swung inwardly into the position indicated in Fig. 3, to completely disclose the door opening, and to provide for the removal of the silage.
The door is secured in position by a plurality of radially disposed pins 11, the outer ends ofwhich are cylindrical in formand slid through guides 12, while the inner or opposite ends thereof are flattened and extend or fit between a pair of operating plates 13, mounted to turn upon a pivot bolt 14, which extends through said plates and through the door. provided at opposite ends with the handle portions 16, is secured to. the outer operating plate, whereby the plates may be turned in either direction to project or retract the fastening pins. The outer ends of the fastening pins are beveled, as at 17, to slide against the edges of the side and cross pieces. The hangers are made rounded at their centers, as at 18. while their ends are flattened as at 19. he hanger bars'not only provide a means for mounting the door in position but may serve as'two of a series of ladder rungs.
From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the inyention will be readily understood Without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the ap ,p'ended claims.
Having thus described our inventi'on, what we claim is: I
1. In combination, a silo door, means for hingedly mounting the door in position to swing inwardly as a whole into the interior of the silo or outwardly from the interior of the silo into the door opening, said means comprising a pair of vertically spaced hanger bars pivoted at adjacent ends to the outside of the door frame and at opposlto ends to the outside of the door, and fastening means for holding the door in closed position, said hanger bars adapted to position at the outside of the silo when the door is closed and to form two of a series of ladder rungs.
2. In combination, a silo door mounted to swing into and out of its door opening, means for locking the door in closed position, said means comprising a pair of operating plates 'revolubly mounted on the door and a series of radially projecting pins pivotally connected between said plates and having outer beveled ends to engage the edges of the door frame and Wedge the door in position and a turning bar provided at opposite ends with handle portions secured to the outer operatin plate, whereby the plates may be turned in either direction to project or retrace said locking pins, and keepers on the outside of the door casing to receive said pins. Y
In testimony whereof We have hereunto set our hands in presence of two subscribing witnesses.
