UNITED STATES PATENT QFFICE.

ERNEST F. WIEDERHOLDT, 0F ST. LOUIS, MISSOURI.

To all whom t may concern:

Be it known that I, ERNEST F. WIEDER- HOLDT, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Silos, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertain's to make and use thersame, reference being had to the accompanying drawings, forming part ofthis specification.

. My invention relates to silos, the principal objects of my invention 'being to construct a comparatively simple and inexpensive silo wall of interlocking brick or tile,the saine being formed so as to resist to a maximum degree the'stresses produced by the weight of the contents of the silos; to form in the silo wall constructed as just described an elongatedvertically disposed opening or a vertical row of openings which permits the delivery of the ensilage to and from the silo; 1go-provide suitable ties across the openiiiig or openings in the silo wall which ties, in e ect, serve the same purpose as the interlocking brick or tile in maintaining the entire wall in tension and transmitting stresses from the wall at one side of the opening to the other; to provide simple means for reinforcing the edges of the opening or openings; to provide simple means for` tying each course of brick or tile in the wall to the reinforcements at the sides of the opening; to provide simple and easily operated doors for the opening or openings inthe wall, and further to generally improve upon and simplify the present types of silos and like structures and materially decrease the cost of constructionI thereof.

It will be understood that the walls of silos and like structures as ordinarily built are provided with an elongated vertically disposed openingfor a vertical row ofopenings, the same being necessary to permit the ensilage to be readily removed'as itis used.

The weight of the contents of a silo exerts outward pressure upon the vsilo wallY and consequently the latter is, when lled or partially lled, constantly in tension, and the strength of the wall to resist the stresses thus produced is to a considerable extent Specification of Letters Patent.

weakened by reason of the openings whichV are necessary to discharge the contents.

Interlocking brick or tile produce an ideal silo wall by reason of the fact that said wall can be easily and cheaply erected and the interlocked members forming said wall afford a high degree of resistance to stresses produced by the weight of the ensilage, but in so fares I am aware interlocking members have never been utilized for producing silos for the reason that no practical way has been found to provide the necessary openings in the wall without greatly weakemng the structure.

By my improved construction of reinforcing the sides of the openings in the wall, tying.- the edges of the wall forming members to said reinforcing means, and arranging ties across said opening, I amV able to produce' a silo or like structure which'has great strength and stability, which will readily withstand the stresses produced by the weight of its contents, and which can be erected at comparatively small cost.

yVVith'tlie'foregoing and Aother objects in viewV my invention consists in certain novel features of construction' and arrangement of parts, hereinafter more fully described,

claimed and illustrated in the accompanying drawings, in vwhich-- Figure l is an elevationalview of a silo constructed inaccordance with my. invention. Y

Fig. 2 is an elevational view of a portion of a silo and showing the doors which normally'close the opening in the silo wall.

Fig. 4 is a horizontal section taken approximately on the line 1 -4L of Fig. 2.

Fig. 5 is a fragmentary view in perspectiveof a 'portion yof one of the reinforcing members at the side of the opening in the silo wall land showing the means employed for tying the edge of the wall to said reinforcing member. i Y Fig. .6 is an enlarged vertical section taken approximately on the line 6 6 of Fig. 4.

Fig. 7 isa detail elevational view of a portion of one of the reinforcing members at the side of theopening in the silo wall lockingy brick or' tile.

and showing the loops which receive the Wall ties.

In thedrawings I have illustratedthe silo Wall constructed "of e=interlocling ihr-ick, 4`the same being laid in courses and each brick comprising a substantially Vrectangular body portion 10 provided on one s'ideanid'at each end With a vertically disposed rib such as 11. The inner faces of these ribs are slightly inclined or underv-clut and When the v.bricks arelroperly*assenfibll'edv or'laid With a double row in each course the rib's vllxfat v'tlreadjacent ends of a pair of bricks in the outer ro`v'vl occupy 'tle sp ace between the ribs fof 1 a brick-inthe inner fro'W. Y

' -It Will be understood, f of 'fcou`rse, 'that f` the bricks are-laid vwithr'rie1"ta1,' cement, brother sel'flhardening "bonding-material.

'The ysilo Wall thus VYcoristructed :is provided vwith fa 'vertically disposed opening and arranged on the edges,1 ofthe'vvall fat'f the sides of this opening are-posts,preferably in the lform of vertically'dispsedfclfannela 12, the flanges 'of which ov'erlie 'the inner and outer facesof theed'ges of saidivall. i(See Fig. 4.) Y l Secured to the face ofthe iweb-offeach channel betxveen the 'llalrgles thereof l"are horizontally disposed `loops 1'3, there being one of these loops for' each course fof the inter- The means employed lfor tying the edges ofthe wan to tile'feiffaneels 12 elemprisessebstantiauyivereedU-shapea anchoring mem bers lfl, preferably "formed offmetal and "as tli'e courses of brick ortile are laid-one upon the other, v"thes/e "anchoring "members fare placed in position With "one "leg inserted through the corresijaondinfg loop v13 "and fthe other' leg` positioned between? the overlapping ribs or llangesl L11 'f the adjacent lpair of brickrior"tilev (See Figsffandb) Thus, the ends of each course :of interlcled'brick or'4 tile forming! the Wallare `edectively A'tied to 'tlie reinforcing channels-12 'Landl the latter are tied lto each other by transverselyblisposed rods 15, the 'end portionsof ltvhich pass throughthe nebsof 'said'channels12- Eachlf these tie rods;isfp'rovidedlvith"nuts on its ends or vvith'lahead on* 'oneendand a nut on the other, and7 positioned' on' each? rod between tile channelsA 13 1s afspacingfmember 16, preferably 'formed' of' tubing. These tie rods act as tensioningmembersito transmit stresses from Lone t side' 'off the openingT to the other and ineffect 'serve the saine'purpose'as thev interlocking brickforf tile :which 'Wo'lild occupy' the opening in case' the'si'loivvere built with a solid imperforate Wall.

FiXedf in'iany suitable manner" to the-Webs of the channels l2 and lproj ecting into lthe opening 4 bet'vve'e'nv sai'dfchaiinels are door stops 17, preferably in'the fornifofrordinary metal 'angles arid-*bearing ta`,gi;air'1'stthe 'edges Vversely disposed` doorfastening bar 20, pref- 'erablyinthe form of la channel, the ends of `which 'bear upon the outer flanges of the channels 12.

The proiecting` end of the bolt 19is threaded and receives a Winged nut 21 Which,"when Vtighter'u-l `on'said bolt, draws the door against stops 17 with the side edges ofpsaid door fitting snugly-against' the innerl portions o'ffchfannels 12; Y

In zFig. f1 y]"ha've shown the usualshe'et metal chute 22 ipositioned over 1 thel opening inthe silo Wall, "which chute yis utilized' When the `'contents of the silo are being 1removed. This chute is f of ordinary lconstruction and forms" no p'art of my invention.

While lI have illu strated and describedf the Wall'of the silo'fasfbein'g constructed of interlocking brick, t'it Will be V"underfstood that practically "the :same kstru f ture "ean' be produced -I"With interlocking tile. Y

"silo foffmy improved construction `is comparatively simple, canfb'eere'oted with comparatively v-little'rcost :and While the-Wall fithe silo is provided With'the "necessary Openingl to'pe'rinitVY the contents of the silo to be readily 1 discharged, the; 'strength of the Wall is 'in nowise impaired, o'iving to the edecti've lmanner in Which vthe edges of' the Wall are tiedtothe reinforcing members at the' sidesE o'f the opening and! the v"manner of tyingsaidreinforcing members te each other.

:This construction v maintains the entire wall in tension 1' and effectively `resists `the stresses' produced by the weight of thevv contents of the silo.

MyA improved structure While particularly adapted "for silos can be advantageously employed l'in any container `or"structure, :the Wall of'ivhich' is provided With anio'p'enin'g or openings, and it Y' is V"desired 'to reinforce and' tie 'said'vvall' across such opening.
