Specification of Letters Patent.

To all whom t may concern:

Be it known that l, JULIUs H. SCHLAFLY,

, My invention relates to improvements in sheet metal structures and more particularly to a chute for a silo, being especially adapted for a sheet metal silo such as shown and described in my application for United j States patent on silos, Serial No. 768,239,

iled May 17, 1913.

The objects of the invention are, to generally improve constructions of the character indicated, to provide an inclosure suHiciently large to permit a man to climb a ladder inside thereof, said inclosure being connected to the silo and extending upwardly over the vertical series of doors therein, so that access to anyone of said doors may be gained by climbing through said inclosure, said inclosure also acting as a chute to direct ensilage thrownV out 'of any of said doors downwardly and prevent the same being blown about or becoming scattered.

Further objects yare the construction of said chute from sections, which may be shipped in knocked-down condition and conveniently erected in connection with the erection of the silo itself `or after said silo has been completed, as may be desired, the mode of connection ofthe various sections con` stituting the chute, also the connection of said sections to the silo proper being important features.

rThe objects thus indicated, together with other objects which will be readily apparent to those skilled in the art, may be attained by the construction illustrated inthe accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In thedrawings Figure 1 is a fragmentary perspective view,.illustrating a portion of a sheet metal silo and a portion of the silo chute connected therto, and embodying my--invention. Fig. 2 is a side elevation of a completed silo, including the chute. Fig. 3 is a fragmentary `perspective view illustrating a part of the silo sections, also a silo door frame, and the chute attaching bars connected to saidsections and portions of Patented May 23, 1916..

the flanges broken away. Fig. 4 is a perspective view of two of the sections of the chute,` portions of the joint supporting strips, being broken away. Fig. 5 is a perspective View of one of the chute braces. Fig. 6 is a perspective view of one of the chute attaching bars. Fig. 7 is a horizontal section view on the line 7-7 of Fig. 1. Fig. 8 is a fragmentary perspective View illustrating portions of the silo sections, a portion of the chute section, and its connection to the silo section, parts being broken away. Fig.

9 is a vertical sectional view on the line p 9 9 of Fig. 4.

Throughout the several views similar reference numerals indicate similar parts.

More specifically describing the construction disclosed in said drawings, the numeral 1y indicates the roof and the numerals 2 the sheet metal sections formin the sidey wall of the silo. rlhe said sections 2 are provided with the horizontal, outstanding, plain ianges 3 at their upper edges and the horizontal, outstanding ianges 4 at their lower edges, the depending flanges 5 being formed integrallywith said Hanges 4.' ln the construction of the silo the sections 2 are arranged one upon another and the flanges 3 and 4 connected, as by means of bolts 6, as clearly described in my said application Serial No. 768,239. rllhe sections 2 are thus arrangedin a vertical series of tiers or courses, and preferably in alternate' tiers are larranged appropriate doors, one of the frames, 7, of which is shown in Fig. 3. No claim, however, is herein made for the construction of said doors or frames. rlhe alternate sections between the doors are preferably provided with ladder rungs 8 and the doors are provided with similar ladder rungs, as disclosed in my said specification, Serial No.`768,239`, thus producing a continuous ladder extending up the side of the silo.

1t is of importance that in connecting the chute to the silo the walls of saidl silo shall not be interrupted by apertures or fastening means of any kind and for the purpose of forming 'a frame or anchor to which said chute mayl be connected, the chute attaching bars 9 are provided. These bars are preferably formed of sheet metal fand constitute an angled body portion having one iange l0 4adapted to extend outwardly from the body'of the silo, and the i Section5 2. At both ends of each bar the vflange 10 is bent overv at right-angles to 4flanges 25, also preferably provided with apertures 26. The flanges are adapted to form the attaching flanges 12, and said attaching flanges are provided with bolt apertures 13 preferably somewhat transversely elongated for convenience of adjustment of jthe parts in erecting the sections. The bars 9 are of such a length that the flanges 12 en'- gage the under-sides of the'flanges 3 and the upper sides of the flanges 4 of the various wall sections and bolts 14 extending through

thefianges

3, 12 and 4 serve to connect the bars to the silo wall. In arrangingthe bars 9, they are preferably disposed end to end in vertical series at the two sides of the doors,

so that one bolt 12 will extend through the.

lower flange of the bar 9, the flange 4 of the section'on which the bar is arranged, the flange 3 of the subjacent section and the upper flange 12 of; the subjacent bar 9, as

clearly illustratedin Fig. 3. The outstandsufficient distance thereabove to give easy ing flanges 10 of the bars 9 are provided with bolt apertures 15 for the chute section attaching bolts, `as hereinafter described.

The chute preferably does not extend enaccess to the interior and to permit arranging an ordinary wagon beneath the lower end to receive the ensilage in cases where it desired to haul the same away from the s o. j A vEach chute section is preferably formed of .sheet metal, having a body portion 16, which extends outwardly from the silo wall at one side of the doors, is Aprovided with a curved, outer portion and returns tothe silo wall in a substantially straight portion at the oppo;

4 site side. At the two ends of each section are provided the inturned flanges 17 and in the Walls of the body portion 16 are provided a plurality ofbolt apertures 18 corresponding to the apertures 15 in the chute attaching bars 9. The flanges 17 adapted to bearranged between the flanges 11` of thebars 9 and the silo sections 2 with the bars 9 ar- 'ranged within the "interior of the angle produced by the flange 17. Bolts 19 are em- `ployed, extendingthrough the apertures 15` and 18l to secure the -chute sections to the` ably of light 'channel iron conforming to the contour of the' chute'sectionsfbolts 21, with their nuts'arranged withn'thechannel of the strip 20, belng provided for 'connecting the chute sections'together and to said strip.

For the purposeof preventin any lateral movement of the chute with re ation to the silo, and to strengthen' and support the structure, the chute-braces 22 are provided,

6 used in fastening the silo sections together extend through the apertures 24 completing the' fastening lof the brace.

v ne of said braces is preferably employed at each joint between chute sections and at each side of.

the chute. r

- The uppermost chute section differs from per edge is not parallel to its lower edge,

portion of the body 16. For the purpose of inclosing the top of the chute the sheet metal roof section 27 is provided, the inner end of which engages the outer side of the sections 2 and the other edges of which are formed with a flangeat28 bent down over `the outer side of lthe uppermost section,

bolts 29 extending through said flange and the body of the uppermost chute section to hold the roof in place.

In that part ofthe roof section 27 adjacent the silo lis arranged a trap door 30,

` preferably provided with hinges at `31 so as ,but is declined Afrom the ends where the flanges 17 are arranged to the ou'ter curved to open outwardly and downwardly, away from' the .main roof 7of the silo. This trap door is suiiciently lar e to permit a man to pass therethrough in order to emerge from the top of the chute inorder toireach the manholes -in the roof 1, one of the same being illustrated at 32. l

In addition to the trapl door 30 thereof section 27 is also provided withv a small skylight 33, which will permit suliicient light `to enter the chute to make the, doors and ladder rungs visible. .While thedrawings and above specification disclose the best'mode in whichv Iv have contemplated embodying my' invention, I 'l desire to be not limited to the ldetails of such disclosure, formany changes in form vand construction may be made, as circum-A stances require or experience suggests, with; out departing from thesprit of the inven tion', within the scope of the appended e claims. V
