D. A. SALNAVE. DOOR FOR SILOS.
APPLICATION FILED MAR. 25, 1913.

comma FLANOGRAPH COuWASHlNOTON D c DEWEY A. SALNAVE, OE BANGOR, MICHIGAN, ASSIGNOR WOOD, OF BANGOR, MICHIGAN.
DOOR FOR SILOS.
To all whom it may concern:
Be it known that I, DEWEY A. SALNAVE, a citizen of the United States, residing at Bangor, in the county of Van Buren and State of Michigan, have invented certain new and useful Improvements in Doors for Silos; and I do hereby 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 doors arranged at the sides of silos to afford access to their interiors; and it consists in the novel construction and combination of the parts forming the door frame as hereinafter fully described and claimed.
In the drawings, Figure l is a front view of a portion of a silo provided with a door and door frame according to this invention. Fig. 2 is a plan view of the same. Fig. 3 is a sectional plan view, taken on the line :12-00 in Fig. l.
The body portion 2 of the silo is preferably circular and it is formed of staves or blocks of cement suitably jointed together and bound by encircling hoops 3. The silo may be of other form however, such as oval, in carrying out this invention, and it may be constructed of any other suitable material besides cement.
A space or opening l is provided at one side of the silo, and this space is closed by one or more doors or door sections 5. The body of the silo has grooves 6, one on each side of'the opening 4, for receiving the edges of the door 5, and packing material 7, such as india rubber, is provided for keeping the door tight at its edges.
Tubular uprights 8 of metal are arranged in grooves at the edges of the opening 4. These uprights are held in place by tubular distance-pieces 9 of metal, having junctionpieces 10 at their ends. The junction-pieces 10 have plugs 11 at one end which fit into the ends of the tubular distance-pieces, and have forked jaws 12 at the other end which straddle the uprights 8. The hoops 3 which encircle the silo are arranged to bear on the junction-pieces 10, which preferably have Specification of Letters Patent.
Application filed March 25, 1913.
Serial No. 756,770.
grooves 14 to prevent the hoops from slipping. The two j unction-pieces forming each pair of junction-pieces are arranged at an angle to each other, and are inclined outwardly from the silo, so that the distancepiece between them is supported infront of and out of line with the uprights. In this manner the distance-pieces form a convenient step-ladder for giving access to the silo.
The forked end portions of the junctionpieces 10 adjust themselves circumferentially upon the cylindrical uprights 8, and when the hoops 3 are tightened the distancepieces and the uprights are all secured in place.
The door 5 has battens 16 on its back to stiffen it, and a locking-bar 17 is pivoted to the center batten at the middle part of the door by a pin 18, and this locking-bar affords a means for holding the door in position. The end portions of the lockingbar are arranged to overlap the uprights 8, and screws 20 are provided for securing its ends to the uprights if necessary. Any other approved means can however be used, besides the screws 20 for holding the door tightly against the body of the silo.
The hoops and cross-pieces hold the uprights in position without the aid of any bolts or similar fastenings, and the framing is very simple and inexpensive to construct.
What I claim is:
1. The combination, with a silo provided with a door opening having grooves at its edges, of uprights arranged in the said grooves, distancepieces arranged out of line with the uprights and forming the steps of a ladder and having end portions which engage with the uprights, and hoops engaging with the silo and with the distancepieces and securing the uprights in the said grooves, by exerting a strut-like thrust upon the distance pieces and the deflected ends thereof.
2. The combination, with a silo provided with a door opening having grooves at its edges, of cylindrical uprights arranged in the said grooves, distance-pieces arranged out of line with the uprights and forming the steps of a ladder and having end poror one- A E ro nnrann Patented Nov. 25, 1913. j
