Application lled March '7, 1912. Serial No. 682,221.

l'o all whom it may cou-cern:

Be it known that EDWARD l. Person, a citizen of the United States of America, residing' at Cassopolis, iu ille omini-y of Cass andStete of lliicbigan, have invented cersilos, and its object to provide convenient means, whereby :i silo muy be constructed of concrete, and to provide 'the sume with various new and useful features hereinafter .more fully described und particularly pointed out in the claims.

My invention consists of a silo construction of numerous slabs of concrete provided with interlocking*V margins and hoops or bands, whereby the Wall ol'itl'ie silo will be substantiel and impervious to moisture, and the slabs of which it is composed adapted to form silos of various dimensions nt pleasure, :is will more ilullyvappear by re'lfcrcnce to the accompanying drawings, in which:

Figure l is an elevation of a silo embodying.; my :invention with the top or cover omitted; Fig. 2 van enlarged detail in vez-tical section on the line 1?-2 of Fig. l; Fig. 3 the same on the line SNS of Fig. il; Fie. 4l a front elevation of one of the door sections; Fig. 5 a front elevation of one of the Wall sections; and Fig. G a partial horizontal section ou the line (i1-6 of Fig. l.

Lilie numbers reifer to like parts in all ol" the iigu res.

Il represents enyconvcnient base formed ol2 concrete und having; an .inner upwardly projecting ilange i? siurouiuled by 'the lower end of the circular Wall of the silo, which wall is composed of numerous small slabs 3, 'the outline of which is e. parallelogram having tivo diagonally opposite acute engles. and two di agonelly opposite obtuse an` gies, seid slabs being arranged in vertical and circumferential series and having concave and convex engaging side edges 5. whereby the curvature of lthe circle may be varied and the edges interlock and :form a tight joint, und also having the upper end convex and the loWer end concave as at 4l, 'whereby rain or Water running down :he outside will not penetrate, but will be shed outward, and the respecerve :sect-.ions "vill be held in vertical alincment, the scams at the ends also being' inclined to the horizontal. Horizontal bands or hoops G surround these walls opposite thc inclined seams, thus crossing said seams diagonally an'l engaging both adjacent upper and lower ends of these sectirms and 'further securing,r the same in place. To provide doors at intervals, a nmnber of vertical. columns of these slabs 3 arc omitted and door casings are inserted in place thereof, as at l); These door cas ings arc preferably substantially square in outline and have concave and convex engaging margins similar to the sections 3.

.l prefer to use two casingsections to cach door and recess the adjacent sides of the same, forming a door opening 911 partially in cach section. Surrounding this opening is n rabbetl l() in which the door 1l is sup ported, which latter may consist of a number of matched strips ol wood, or a slab of concrete, and is held in place by the contenis ofthe silo. If preferred, the seams of this structure may be further secured by means of suitable cement placed therein as the structure is assembled. This I do. not consider essential however.

The top and bottom circlunfercnlial se ries of the slabs and door casings have their upper and lower cud surfaces horizontal. These concrete parts 3 and l) are readily made in any suitable molds and can be semblcd to form cylindrical silos of various diameters' without change and also can be builtI at various heights by greater or less number of circumferential series as occasion requires. The hoops or bands 6 are 'preferably of round rod and provided with the usual olitu'zirtlly turned lugs 8 and tighten- .ing bolt 7, the length of these hoops being varied to conform to various diameters as occasion requires. l`his structure when assembled is substantially water proof and forms a very durable and satisfactory structure for the purpose. Any usuel cover (not shown) may be used and forms no part of this invention.

l. A silo, comprising numerous'slabs of concrete arranged in circumferential and vertical series, the seams between the superposed slabs being .inclined to the horizontal, and horizontal bands or hoops crossing the seams and engaging both adjacent ends olf the slabs.
