EDWARD H. JONES, OF FAIRBURY, NEBRASKA.

CONCRETE DOOR-FRAME FOR SILOS.

To all whom it may concern Be it known that I, EDWARD H. Jones, citizen of the United States, residing at Fairbury, in the county of Jefferson and State of Nebraska, have invented certain new and useful Improvements in Concrete Door-Frames for Silos, of which the following is a specification.

My invention relates to building constructions and particularly to silos.

The primary object of my invention is the provision in a silo constructed of wood staves, of a concrete door frame, preferably extending from top to bottom of the silo and preferably molded in situ and having a plurality of openings at various levels for the usual doors.

A further object is to so form the concrete door frame that it may be easily molded in lace.

A still further object is to so construct the frame that the hoops which surround and hold the staves of the silo in proper position shall act to reinforce the door frame and hold it in place and hold the staves in snug engagement with the frame.

A still further object is to construct the concrete door frame with vertical reinforcing members extending from top to bottom of the door frame, and a still further object is to construct the door frame in sections, the sections being held in engagement with each other by the vertical reinforcing members which exert a clamping action upon the sections and each section being held in place by the said hoops.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein-- Figure 1 is a sectional perspective view of a silo with my improved door frame in place; Fig. 2 is a sectional perspective view of one of the blocks or sections of the concrete door frame; Fig. 3 is a horizontal section throughthe middle of one of the door sections and the false work forming the mold whereby the section is molded; Fig. 1 is a perspective view of one of the separating plates; Fig. 5 is a perspective detail view of the door which forms the mold whereby the door openings are molded in the door frame.

Referring to Fig. 1, A designates a silo of any usual or ordinary form and consist-- ing of vertical staves 2. These staves extend, as usual, nearly entirely around the Specification of Letters Patent.

silo and form the main portion of the wall thereof, but a space is left at-one point of the circumference of the silo which extends vertically from top to bottom to provide for the door frame. The jamb staves which are disposed on each side of this opening are designated 2. Preferably each stave is formed with a tongue 3 and a groove 4: to receive the tongue of the next adjacent stave. The door frame may be molded solidly in concrete or like artificial stone or be molded in sections. The shape of the door frame whether molded in sections or monolithic is the same. Preferably, however, it is made in blocks, designated generally 5, one of these blocks being illustrated in Fig. 2. Each block is approximately rectangular in face view and surrounds a centrally disposed door opening 6 which extends through from the front face 7 of the block to a vertical plane, cutting the middle of the block, and then extends laterally as at 8 and then laterally and outwardly to form a beveled outer face 9 adapted for the reception of a door having a beveled inside face which will be later described. It will be seen that the inner face 10 of each block, forming the door frame, is flush with the inside faces of the staves 2. Each block 5 is also formed with a vertically extending rib or tongue 11 and a vertically extending groove 12 adapted to receive the corresponding tongue or groove upon the staves 2, so as to interlock the door frame with the staves. Each block 5 is formed below the door opening 6 with a transversely extending passage 13 lined with pipe 18 through which the hoops 1 1 of the silo are adapted to pass. Each block is also preferably formed with parallel vertically extending passages 15 disposed one on each side of the door open ing and adj accnt the front face of the block. Each of these passages is preferably lined by a pipe 15 which has a length equal to the height of the block, for the passage of vertically extending clamping rods forming elongated bolts, and designated 16. Immediately below each door opening and on each side of the door openings are located outwardly projecting bolts 17, these bolts being embedded in the concrete of the block and forming means for supporting the rungs of a ladder. The rods 16 extend downward the full length of the silo and the lower ends of the rods are formed with heads 18 which are embedded in the concrete foundation of the silo. The upper ends of the rods are screw threaded and are provided with nuts 20 or other clamping means, whereby the vertical reinforcing rods 16 may be put under tension to clamp the sections of the door frame, or place the monolithic door frame (if the door frame is constructed in one piece) under tension.

Preferably, as before remarked, the door frame is molded in sections, each section forming a block 5, as previously described, and each section being separated from an adjacent section by plates 21 preferably of sheet metal, these plates being perforated at 22 for the passage of the vertical reinforcing members 16. These plates have the same cross sectional area and form as the blocks 5 or sections. Preferably the blocks or complete monolithic door frame are molded in situ and not put in place after being molded, and I have designed my door frame with particular reference to its being easily moldedin place, the means to this end being illustrated in Fig. 3.

After the jamb staves 2 of the silo have been erected, blocks 23 are disposed on each side of the door opening and against the inner faces of the staves 2 and blocks 24, of like character to the blocks 23, are disposed on each side of the door opening and against the outer faces of the staves 2 Bolts 25 pass through each block 24, the adjacent stave 2 and corresponding block 23. Vertical strips 26 are nailed or otherwise attached to the inner faces of the blocks 23, these strips being spaced outward a suitable distance from the adjacent face of the stave 2 so as to leave preferably about one inch between the strip 28 and the plane of the outer face of the stave 2 two inch planks 27 forming a backing for the concrete, are then disposed behind the strips 26. Strips 28 are attached to the inner faces of the blocks 24 so as to project over the door opening, and one inch plank backing, designated 29, is placed behind these cleats or strips 28. The space defined by the planks 27' and 29, and the inner faces of the staves 2 is intended to be filled with concrete.

The door opening proper, referred to and designated 6, in the concrete block 5 is formed by a door mold, illustrated in Fig.

5, and designated 30. This mold is rectangular in elevation and is formed with beveled edges 81. The face of the mold is temporarily provided with outwardly projecting vertically disposed parallel strips 32, and the space between these strips is filled in, in any suitable m2l-I1I181,,21S by wooden transverse pieces, designated 83.

It will be understood that this door mold is to be attached to the planking 27 orv to the backing 29 in any suitable manner. In order to hold the blocks 23 in proper spaced relation while the concrete sets, I provide.

transverse cleats 34 nailed or otherwise attached to the blocks 28. For the same purpose, I provide transverse cleats 35 which are attached in any suitable manner to the blocks 24. The mold formed by blocks or

timbers

23 and 24, the

strips

26 and 28, and the

backing planks

27 and 29 extend the full height of the silo. The

backing planks

27 and 29 are put in position as needed, and the entire door-frame is molded in one day or more, as is most convenient. The

strips

26 and 28 are not removed, nor is the plank backing removed until entire door-frame has set.

The vertical rods 16 will, of course, be put in place in the door opening. The mold boards or members just described will then be put in position, and the first. or lowermost block forming the door frame will be molded. WVhen this is set the members of the mold will be removed and one, of the sheet metal plates 21 will be put in place. The elements of the mold will again be assembled in the manner shown in Fig. 3, and

.a second section ofthe door frame will be molded. A second metal plate 21 will be placed upon the top of this section when the concrete is set. This operation will be repeated until the entire door frame is molded, after which the false-worker mold boards will be removed entirely and the silo will be ready for use. Doors, of course, will be pro vided for closing the opening 6. Preferably these doors are constructed as in Fig. 5, and each door is preferably used for the purpose of molding its proper dooropening. The door 30 preferably consists of twolayers of planks extending at right angles to each other.

The outer face of each door willbe temporarily provided with outwardly projecting strips 32 which will extend into and rest against the vertical sides of the outer portion of the door opening 6. Before each section is molded the hoop which passes around the silo at the level of the, section may be passed through the pipe 13*? of the section, and after all the sections are inplace the nuts 20 or like tensioningdevices are placed upon the upper, ends of the rods 16 and turned down until the rods are under tension. It will, ofcourse, be understood that the j amb staves 2 are pierced; or notched or grooved transversely on theirinner faces to accommodate the hoops 14.

It will be seen that by constructing the door frame in sections separated from. each other by plates of sheet metal it ispossible ciently to allow a hack saw to be used upon the bolts 16.

It will be seen that my improved concrete silo door frame is capable of being used with a wood stave silo, and is adapted to be put in place using a removable form. It is also capable of being built in sections in place and it is reinforced both vertically and horizontally. The hoops which run around the silo also hold the concrete door frame in position. As the sectional frame is provided with vertical reinforcing rods or tie-rods, the sections of the frame are securely held to the foundation, therefore preventing leakage of air at the sections of the door frame.

Having described my invention what is claimed as new is:

1. A silo comprising a body having a Vertically extending opening, and a concrete door frame extending from top to bottom of the silo and filling said opening, said door frame being formed with a plurality of door openings, tie-rods embedded at their lower ends in the foundation of the silo and extending vertically upward through the door frame, clamping means on the upper ends of said rods, and hoops surrounding the silo and passing through the door frame.

2. A silo comprising a foundation, a silo body erected on the foundation and having a vertically extending opening, a concrete door frame filling said opening and having a plurality of door openings vertically extending tubular members embedded in said frame, and tie-rods embedded at their lower ends in said foundation and extending up through said tubular members.

3. A silo comprising a body formed with a vertical opening, a door frame filling said opening and composed of a series of superposed concrete blocks, each block being formed with a door opening, a transversely extending hoop passage and a vertically extending tie-rod passage, separating plates disposed between the blocks and havlng perforations registering with the tie-rod passage, vertically extending tie-rods disposed in said passages, and hoops surrounding the body of the silo and extending through the hoop passage.

4. A silo comprising a body portion formed of vertically disposed staves and having a vertically extending door opening, jamb staves disposed on either side of the door opening and a door frame interposed between said jamb staves and formed of superposed concrete blocks each block having a door opening, each of said blocks projecting outward beyond the outer face of the body of the silo, and each block being formed in this projecting portion with a transversely extending hoop passage extending entirely across the block each block being also formed with vertically disposed passages, the passages of one block alining with the passages of the next adjacent block, hoops surrounding the body of the silo on the exterior thereof and passing through the jamb staves and the horizontal hoop passages in the several blocks, and vertically extending tie rods disposed in the vertical passages of the several blocks and holding the several blocks in engagement with each other.

In testimony whereof I aflix my signature in presence of two witnesses.
