MAX H. JAHN, OF MAYFIELD, NEW YORK.

SILO.

To all whom it may concern:

Be it known that 1, MAX H. J AHN, a citizen of the United States, residing at Mayfield, in the county of Fulton and State of New York, have invented certain new and useful Improvements in Silos, of which the following is a specification.

The object of this invention is to provide means whereby a farmer may build a silo of any desired height without the use of an extensive set of tools. A further object of the invention is to provide a silo which may resist the action of frost upon the feed placed therein, and a still further object of the invention is to provide means whereby the capacity of the silo may be increased as the need therefor arises.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a s1lo embodying my improvements;

Fig. 2 is an enlarged vertical section on the line 22 of Fig. 1;

Fig. 3 is an enlarged horizontal section on the line 33 of Fig. 1;

Fig. 1 is a perspectlve view of two of the sections of which the silo is composed;

Fig. 5 i a vertical sectional View illustrating the manner of anchoring the S110 so that it will resist the action of high Winds.

In carrying out my invention, I employ sections which are superposed to form the wall of the silo and these sections each consists of inner and outer rails or plates 1 and 2 which will preferably be boards or strips of lumber. The said plates or strips are secured to opposite sides of studs 3 which are disposed near the ends of the strips and are so arranged that their upper ends will project above the upper edges of the strips, while their lower ends .will be above the lower edges of the strips. The ends of the strips 1 and 2 are beveled, as shown at 4, and said ends are staggered with reference to the studs, that is to say, as shown most clearly in Fig. 3, the strips or boards are arranged so that one end of the outer strip will be nearer the stud than the corresponding end of the inner strip while the opposite end of the outer strip will be more remote from'the adjacent stud than the corresponding end of the inner strip. This arrangement permits the meeting ends of the sections in the same tier or course of the silo to overlap so that the inner strip of one section will bear against the inner surface of Specification of Letters Patent. Patented Feb, 10 1920, Application filed July 15, 1916. Serial No. 245,095.

' the outer strip of the meeting sectionand will, in turn, have its inner surface bearing against the adjacent end of the inner strip of the meeting section so that the sections will be mutually braced and interlocked at their meeting ends. The beveling of the ends of the strips, moreover, permits the strips to fit togetherin angular relation so that a silo of polygonal horizontal outline may be formed. It will be apparent, upon reference to Fig. 3, that the meeting ends of the outer plates will form seams or joints.

These seams or joints I cover by metallic strips 5 which are nailed or otherwise -secured to the outer surfaces of the sections and extend over the meeting ends so that the joints will be thoroughly covered and the access of frost or moisture to the interior of the silo will be prevented.

It will, of course, be understood that the sections are superposed so as to build the silo up to any desired height and the sections are brought automatically into vertical alinement by causing the lower'ends of the studs in an upper section to rest upon the upper ends of the studs in'the immediately subjacent section. The sections will thus be made to register without requiring an extraordinary amount of care upon the part of the builder and shifting of an upper section inwardly or outwardly will be prevented by the engagement of the studs between the strips or boards of the upper section, collapse of the silo v being thereby avoided. I

In one wall of the silo, I employ at intervals short sections 6 which have their inner endsclosed by posts 7 whereby a door frame is produced. The faces of the door frame converge inwardly, as shown clearly in Fig. 3 and withinthe door opening I fit a door 8 which is composed of inner and outer walls whereby an air space 9 is provided in the door. To retain the doors in position, I employ a locking bar across the outer face of each door and this locking bar consists of sections 10 which are hinged together at their centers, as indicated at 11, so that the bars may be folded upwardly but will be prevented from folding downwardly and the intermediate portion of each bar is off- 7 as shown at 13, to the adjacent door frame and the opposite end engages a loop or keeper 14 so that the bars will'be held in contact with the outer surfaces of the doors and will thereby retain the doors in position.

In order to insure stability in the structure, I place the lower sect-ionsupon a foundation 15 of concrete or similar material in which is anchored the lower end of a' stay 16 which extends upwardlythrough the silo between the inner and outer walls thereof and has its upper extremity threaded,

as shown at 17, and inserted through a cap plate 18 fitting on and bridging the upper edges of the inner and outer walls. A nut 19 is mounted on the threaded extremity of the stay and is turned home against the cap plate so as to clamp the superposed sections in their superposed relation as will be readily understood. The stay 16 may consist of a metallic rod or bar or a series of rods or links having their ends connected in any convenient manner, the number of the rods or links depending upon the height of the silo. A roof of any desired construction may tions may be furnished in various sizes so that a silo of any desired diameter may be formed therefrom and, as the sections are merely placed one upon another and the forms of their ends prevent'them being placed end to end except in the prescribed manner, the silo may be rapidly build by unskilled labor. The stays by which the silo is anchored in place pass up through 'thewaflls so that they do not detract from the appearance of 'thesilo nor interfere with the placing of fodder therein and the construction of the-independent sections is such the t the completed silo will have inner and outer walls with a dead airspace between them and, therefore, the contents of the silo will be protected against the actlon of frost or excessive changes 1n temperature. I The cost of the several sections is obviously very slight and a silo of considerable capacity maybe built without incurring a burden some expense. Moreover, a comparatively smallsilo may be. originally built and the height of the same extended from season to season so that the cost of a silo of great capacity may be very easily met.

Having thus described my invention, what is claimed as new is:

-A hollow-wall silo composed of superposed and abutting panels, each panel conslstmg of vertical studs and inner and outer horizontal strips secured to the opposite sides of the studs, the studs being spaced from the ends of the strips and the upper and lower-ends of the studs being respecti ely above the upper and lower edges of the-strips whereby the studs of each panel will enter a superposed panel with the studs of all superposed panels in, vertical alinement and the studsof eachsuperposed panel resting on the studs of asubjacent panel, and the ends of the strips projecting beyond the studs in staggered relation with the opposite ends of the strips beveled in opposite directions whereby the inner stri p of a panel Wlll bear at one end against the lnner side of the inner strip of one abutting 'panel at a point spaced from the end-of the latter and at itsop'posite end will extend across another abutting panel and bear against the inner side of the outer strip thereof between the end of the same and the adjacent stud, and the-outer strip of each section will bear at oneend against the inner face of the outer strip of an abutting section and at its opposite end; will have its beveled edge flush with the outer face of the outer strip of another abutting section, covering'strips secured upon the outer faces of abutting panels at the vertical joints be- ,tween' the same, and means for anchoring the super-posed panels.

In testimony whereof I afiix my signature.
