'UNllTElDl @TAE PATENT JAMES J'. HCLMES, OF KANSAS CITY, MISSOURI.

SILO.

Application filed March 14, 1914.

To all whom t may concern.' Y

Be it known that l, JAMES J. HOLMES, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful improvements in Silos, of which the following is a specification.

This invention relates to silos and has for its object to produce a structure of the character named which can be erected at a minimum cost and possesses the desirable qualities of strength and durability.

A further object is to produce a silo in which the walls are secured in place without the use of nails or other securing devices and are adapted for expansion and contraction in a vertical direction without opening any oints or seams through which rain can enter the silo or through which seepage from the latter can take place.

With these general objects in view, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and pointed out in the appended claim, and `in order that it may be fully understood reference is to be had to the accompanying drawing, in which- Figure 1, is a fragmentary plan view of a silo embodying my invention;

Fig. 2, is an enlarged section on the line II-II of Fig. 1;

Fig. 3, is a fragmentary plan on a scale much greater than that of Figs. 1 and 2;

Fig. el, is an elevation of the interior of the silo showing the arrangement of the doors thereof.

Fig. 5, is a vertical section on the line V V of Fig 4.

In the said drawings, 1 indicates a concrete or equivalent solid and substantial bed to provide settings for a series of posts, each preferably consisting of a central member 2, and two side members 3, secured to the central member by bolts el: and nuts 5, the inner edges of the flanking members 3 being beveled to provide in conjunction with t-he adjacent sides of member 2, a pair of V-shaped grooves 6, the bevel of the inner edges of members 3, being determined by the number of posts employed in the erection of the silo, which is adapted to be of polygonal form, though it may vary as regards the number of its sides.

To impart stability and strength to the posts, particularly if composed of members Specication of Letters Patent.

as indicated as preferable, U-shaped clips 7 are fitted around the outer edges of said members and outer sides of the members i5, and the securing bolts 4 extend through said clips. The clips are provided with out wardly projecting lugs S, as supports for horizontal clamping bands 9 which encircle the silo and guard against outward springvw ing of the posts, and to cooperate with these bands a number of opposite posts may be connected at their upper extremities by tierods, each consisting of two members 1U connected by a turn-buckle 11, the ends of the rods extending through the central members of the posts and through the topmost clips 7 and being engaged by clampingnuts l2 which bear against the outer faces of said clips.

The walls of the silo are double and constructed as follows: The outer layer of boards 13 have their upper edges beveled downwardly and outwardly at 14 and their lower edges formed with an obtuse angle shaped groove 15, so that the groove of one board shall snugly receive the beveled upper l edge of the immediately underlying board,

and the ends of all the boards are beveled so as to converge inward and form an angle corresponding to the angle formed by the sides of the grooved faces of the posts, the boards being of such length as to fit snugly in said grooves and yet be capable of movement in a vertical plane.

The inner part of the silo is composed of boards 16 of exactly the same construction as those described except that they are slightly shorter to iit between the innermost portions of the central members of the posts and are arranged in reverse position, that is to say are arranged so that their beveled upper edges shall slope downwardly and in wardly. Furthermore the boards forming the inner wall are arranged in brealrnjoint relation to the boards forming the outer wall as shown clearly in Fig. 2, and to maire the walls air-tight to protect the ensilage against freezing, an insulation 17 of building paper or equivalent material is arranged between the inner and outer walls as shown.

At one side the silo will be provided with a wall composed of door and wall sections alternately arranged, see Figs. l and 5. In said figures horizontal boards 18, 19, and vertical boards 2O and 21 constitute door frames adapted to be slipped down in the grooves 6 in the same manner that the Wall sections are secured and hinged in each frame is a door 22 adapted to open inwardly and secured to each doorl are turnbuttons 23 to be turned to lap the outside ofthe respective door frames and thus secure the door against accidental opening.

The manner of charging this silo With ensilage and removing the ensilage therefrom is the same as that of any other silo, it being noted as hereinbefore suggested, that in wet weather the height of the walls of the silo may increase through expansion and sliding thereof in the grooves of the posts, and that in dry weather contraction ,of the boards will result in a reduction in the height of the walls, it being further noted that the tension of the tie rods can be varied by proper manipulation of the turn buckles 1l, and that the tension of the band 9 can also be varied in the usual and Well known manner. lt will also be noted that the obtuse angle formation of the upper and lower edges of the boards not only ina-ke provision for shedding of moisture away from the walls, but makes each board without the use of nails or the like, support the boards above it Without any tendency to act as a wedge to force the supported board outwardly midway between the posts and thereby facilitate outward bowing thereof and the production of open joints.

From the foregoing it will be apparent that I have produced a silo embodying the features of advantage enumerated as desirable and which is susceptible of modification in minor particulars Without departing from the principle of construction involved.'

I claim: Y

A silo comprising a series of upright posts, each provided at its inner corners with a pair of acuteangle shaped grooves, walls connecting adjacent posts and composed of substantially horizontal boards fitted together edgewise in superposed relation, the ends of the boards conforming to the angular shape of said grooves and fitting JAMES J.
