SILO-DOOR-ATTACI-IING MEANS.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed February 2, 1914. Serial No. 816,128.

To all whom it may concern:

Be it known that I, JULIUs H. SOHLAFLY, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Silo- Door-Attaching Means, of which the fol lowing is a specification.

My invention relates to improvements in the construction of door attaching means, and while applicable to doors of various kinds and for various purposes, is more particularly adapted for silo doors.

The objects of the invention are, to generally improve the attaching means for doors of the character mentioned to provide a door attaching means especially adapted for silos and the like, which will be strong and durable, easily operated, capable of producing a substantially hermetical closure and involving few and simple parts.

These objects, together with other objects which will be apparent to those skilled in the art, may be attained by the construction illustrated in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the drawings Figure 1 is an elevation of a portion of a sectional sheet metal silo provided with a door embodying my new invention. Fig. 2 is a perspective View of a portion of said silo and the door frame. Fig. 3 is a perspective view of the door its-elf. Fig. 4 is a perspective view of one of the locking wedges. Fig. 5 is a perspec tive view of one of the hinge wedges. Fig. 6 is a perspective view of one of the locking wedge housings. Fig. 7 is a vertical sectional view taken on the line 77 of Fig. 1. Fig. 8 is a horizontal sectional view taken 011 the line 8-8 of Fig. 1, showing the door in sealed position. Fig. 9 is a similar view showing the door in unsealed and partly open position.

Throughout the several views similar reference numerals indicate similar parts.

More specifically describing the construction disclosed in said drawings, the numerals 1, 2, 3 and 4 indicate several sheet metal sections connected together at their edges and forming a portion of the wall of the silo.

A door-frame formed of sheet-metal and comprising the flanges, 11, 12, 13, 14L and 15 is connected to the sections 1, 2, 3, and t by means of the bolts 8 and 18.

The sheet-metal door provided with the body 19 is adapted to close the opening 20 of the door-frame when shut against the flanges 11, 12, 13.

Connected to the body of the door by means of the bolts 25 are two, vertically spaced bars 26. Intermediate the side edges of the door said bars may be bent outwardly from the body 19 to form ladder rungs, as clearly illustrated in the drawings.

For the purpose of hinging the door to the frame the free ends of the bars 26, at one side of the door, hereinafter called the hinge side, are provided with integral knuckles 27 adapted to receive the hinge wedges 28, as presently described. Connected to the dooni'rame at the hinge side of the door by means of bolts 29 are the hinge wedge housings formed from sheet metal and providing a lower wedge loop 30 and an upper wedge loop 31, said lower loop 30 extending outwardly from the door-frame a greater distance than the loop 31, and a knuckle receiving opening 32 adapted to receive the knuckle 27 of one of the bars 26 beingdisposed between said lower and upper loops. The hinge wedges 28 extend through the loops 30, knuckles 27 and loops 31 forming hinge pins upon and about which said knuckles are adapted to rotate. The larger ends of said hinge wedges are downwardly disposed, and some means, as the rings 33, extending loosely through aportures in the upper, small ends of said wedges should be provided to prevent said wedges from falling downwardly so as to become entirely detached from the wedge housings. It will be readily understood that the wedges 28 may be driven upwardly so as to force the knuckles 27 toward the doorframe, and thus firmly seat the hinge side of the door against the flanges of the said frame. At the same time it should be noted that regardless of the fact that the hinge wedges have been driven upward until they tightly engage the loops 30 and 31 so as to produce th sealing action just described the door will usually be free to swing open upon said wedges, acting as hinge pins, even without driving said hinge wedges loose, as the initial movement of the knuckles 27 upon said hinge wedges will have a tendency to dropping entirely out only by the engagement of the rings 33with the upper loops 31. For the purpose of providing means whereby to lock and hold the door in closed position the bars 26 are provided with free.

ends extending beyond the free-edge of the door and constituting locking tongues 3% on the locking side of the door. Said tongues 3e are adapted to approach the door-frame when the body of the door is seated against the flanges of the said frame. For the purpose of locking said tongues in said position and producing a clamping action adapted to thoroughly seal the door, locking wedge housings 35, similar to the hinge wedge housings heretofore described, are provided. Said housings 35 are disposed with their larger wedge loops 30 above their smaller wedge loops 31 the tongues 34 being adapted to be received between said loops 30 and 31 and locking wedges 36 are provided and adapted to be arranged within the loops 30 and 31 in front of the tongues 34 to draw said tongues toward the frame and hold the door in locked position. It will be understood that the wedges 36 are disposed with their smaller ends downwardly and that, in order to open the door, said wedges are entirely removed from the housings 35. In order to prevent said wedges from being lost, therefore, I prefer to provide soft flexible connections, such as the chains 37 connected to the silo and to the rings 38 in the larger ends of said wedges. In closing and sealing the door the wedges 36 may be driven downwardly with a hammer or other implement, as the wedges 28 are driven upwardly and in order to unseal and open the door it is only necessary to drive said wedges by upward blows on the lower, smaller ends, as will be readily understood. Attention is here called to Figs. 8 and 9. Fig. 8 illustrates the door in the closed, locked position, the wedges 28 and 86 holding the door firmly pressed against the flanges of the door frame and Fig. 9 illustrating the wedges 36 removed and the door swung partly open, the hinge wedges 28 having fallen to their lowest position and thus not only freeing the hinge edge of the door from the flange 13, but so loosening the hinge connection of the door as to make it freely swing into the open position.

Copies of this Although the drawings and above specification disclose the best mode in which I have contemplated embodying my invention, I desire to be not limited to the details of such disclosure, for many changes in form and construction may be made, as circumstances require or experience suggests, without departing from the spirit of the invention, within the scope of the appended claims.

I claim:

1. A silo door attaching means comprising, in combination with a silo door frame and door, hinge means, including longitudinally slidable wedge shaped hinge pins, connecting one side of said door to said frame and locking means, including longitudinally slidable locking wedges, for locking the other side of said door to said frame, said hinge pins and locking wedges adapted to cooperate to draw the door into sealing contact with said frame when said door is closed and said pins and wedges are driven taut.

2. A silo door attaching means comprising, in combination with a silo door frame and door, hinge means, including wedge shaped hinge pins disposed with their smaller ends upward, connecting one side of said door to said frame, and locking means, including locking wedges disposed with their smaller ends downward, for looking the other side of said door to said frame, said hinge pins and locking wedges adapted to cooperate to draw the door into sealing contact with said frame when said door is closed and said pins and wedges are driven taut, and said hinge pins adapted to drop by gravity to ease the hinge connection when said door is opened.

3. In a construction of the character described, in combination with a door frame and door, wedge-operable hinging means connecting said door to said frame and comprising eye or knuckle members connected to said door frame and door respectively and a wedge shaped hinge pin connecting said eye or knuckle members and adapted, when driven taut, to draw said door toward said frame. V

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
