To all whom it may concern:

Be it known that I,.JHN S. Moan, a citizen of the United States, residing at Dallas,

. in the county of Dallas and State of Texas, have invented certain new and useful Im-,

pfrovements in Silos, of which the following is a specification.

My invention relates to new and useful imp o ements n s l s object is to Pr vide a silo of the interlocking cement stave type hat ll be a u ely irightand water-tight and will preserve silage perfectly under a l Weather conditions.

noth bject s t p o a p oved method of fasteningthe hoops upon a-ce-' ment stave 110- A fur her bje t is t in a ri s f. d ors contmu sly extending from its QP t s bottom, mp v d fas ing devices being correlated with said doors.

F'nally, a still further object of the invention is to provide a device of the champter described that will be strong, durable, efiicient and simple, and comparatively inexpensive to produce, and also one in which the s ver P r w ll t be l ly t out of workingorder.

lVith the above and other objects in view, the invention has relation to certain novel features of construction and operation, an xample of. which is lowing specification and illustrated in the accompanying drawings, wherein:

Figure '1 is a view in front elevation of a silo, in which are embodied thenovel'features constituting my invention. Fig. 2 is a rear view ofthe same. Fig, 3 is a transverse sectional view, the sectionI being taken upon the line m-w of Fig. 6. Fig. 9 is a vertical sectional view, the section being taken upon the line y-y of Fig. 6.

Referring now more particularly to the drawings,

serve as a foundation for my silo. The .cy-

lindrical silo wall which rests upon the foundation 1- is com .rised of rectangular cement staves 2 form ng tiers, the horizontal joints of each tier, being staggered with relation to those'of the adjacent tiers, The

interlocking tongue and groove joints between each stave and the adjacent staves of the same her are indicated at 3, similar I joints4 being formed between abutting lat eral edges ofthe staves.

r The cement floor of the silo, which is designated by the numeral 5, is supported at its edges by the foundation 1. I

' 'At one side of the silo, there is provided a vertical series of doors 6, extending the full height of the silO and preferably formed of wood. In each of the staves 7 between which the doors 6 are fitted, there is embeddeda reinforcing steel rod 8, forming. an obtuse angle, the apex of which pro ects slightly from the stave intermediate of its ends.-

Between 4 each two adjacent doors 6. there is interposed a combined sill-and lintel 9, which has its extremities supported by the staves7 adjacent to the door beneath said' lintel, the staves being formed with cutaway corners to receive the lintel's. In the cement'comprising each'member 9, there are m edd d wo horiz nta r o g rods.

tially the full lengthof the sill and formed at their extremities with eyes 11 in grooves 12' vel tially extended across the sill ends.

The eyes 11' of the upper and lower rods 10 of each sill respectively receive the lower extremities of the reinforcing rods 8 just above said sill and the upper extremities of the ,rods 8 just below the sill. Each door 6- is mounted in the rear portion ofthe door aperture and has its lateral edges abutting 10, one above'the other extending substanforwardly against vertical shoulders 13 formed'in the members 7, and its lower edge abutting against a horizontal shoulder 13 in the correlated sill. Through the center of, each door there is transversely passed a 'bolt 15 carrying a sleeve 16 in front of the door and a latch arm 17 in front of said sleeve. When said latch armis displaced I to a-horizontal positionits extremities will project slightlybeyond the lateral edges of the door, 'overlappin the staves 7 and restricting the door against rearward displace ment. -The latch arms 17 may be clamped in their horizontal positions by handled 1 H, clamping nuts 18 mounted upon the front ends of the bolts 15. Upon the end portions of each door there are respectively mounted forwardly projecting arched brackets 19 which may serve both as door handles and as ladder rungs. I

The silo walls are held to their cylindrical shape by two alternating series of hoops respectively designated by the numerals 20 and 21, and preferably having the nature of steel bands. Each of the hoops 20 is contiguous with one of the members 9, the outer faces of said members being grooved as indicated at 22 to receive said hoops. The hoops 20 are each formed in two halves the joints being vertically alined at each side of the silo. These joints will preferably be formed by passing the end portions of a hoop through small brackets 23 and subse'- quently bending over the hoop ends, preventing removal of the brackets from the hoop. Through the two brackets is passed a bolt 24, permitting considerable force to be exerted in tightening the hoop upon the silo. The hoops 21 are-disposed midwaybetween-the hoops 20, and are also formed in two halves, which are joined together at the rear of the silo in, the manner already described. At the front of the silo, the other extremities of the halves of each hoop are respectfwelyv engaged with the projecting portions of two opposite members 8. Thus it is seen that the hoops are so arranged as to avoid obstructing' thedoor apertures in any way. The roof 25 is preferably made of sheet-metal and has the form of a cone of gradual inclination.

The disposition of the hoops 20 and 21 is ,such that said hoops together cover all of the horizontal joints between the staves, each stave thus being engaged by hoops at both ends and at the middle, producing a very strong structure. To have access'to the silo by any of its door apertures it is necessary only to loosen the clamping nut 18, turn the vtraversing the correlated bar. 17 through a slight angle, and displace the door into the silo from the door aperture. The reinforced construction of the 'stave s 7 andmembers 9 adequately compensa'tes for the reduction of strength in the front portion of the silo wall resulting from the presence of the door apertures.

The invention is presented as including all such modifications and changes as properly come within the scope of the following claims.

l Vha'td claim is;

1. In a device of the character described two door jambs, each of said jambs consisting of a plurality of-sections, cross braces between the two ja'mbs, rods trave'rsing said cross braces and projecting therefrom, the

projecting ends being formed into loops, a rod traversing each of "said jamb sections and projecting therefrom,flall arranged so that the projecting portions of each rod combination with" adjustable tie bands'encircling the body ofthe silo, said bands therein. C
