WILLIAMHANSON AND`ANTON PALMQUIST, OF IBA-BRON; WISCONSIN.. .Y
Specication'cf Letters Patent.
Application filed March 23, 1911.
To (LLL whom it may concern' Be it known that we, lViLLr-AM Hanson and ANTON PALMQUIST, citizens Aof the United States7 residing at Barron, in the county of Barron and State of lVisconsin, have invented certain new and useful lm- Yprovements in Silos, of which the following is a specilication, reference being had to the. accompanying drawings...
This invention relates to improvements in roofed cylindrical structures and particularly to improvements in such structures the cylindrical wall of which is made up of staves; a silo is a common example of such a structure.
An object of this invention is to provide a structure of the character just mentioned with a roof which will not interfere with the inward and outward movement of the staves which make up the cylindrical wall and which are commonly held together or bound by hoops.
ln thedrawings illustrating the principle of this invention and the bestmode now known to us of applying that principle. Figure 1 is a perspective view of a silo embodying this invention, the roof being shown removed; Fig. 2 is a fragmentary elevation showing the roof timbers in place; Fig. 3 is a section on the line AA, of Fig. 2; Fig. i is a perspective view of the roof timbers assembled; and Fig. 5 shows the roof boards in place upon the roof timbers of Fig. 4. 1
. The cylindrical wall of the silo a is made up of the staves b which are bound together by the hoops c. The ends of the latter are formed with ears (Z which are held together bv bolts e; and by loosening and tightening these bolts the hoops be adjusted toallow for the contraction and expansion of the staves. The cylindrical wall of the silo is providedin the usual manner with the doors f. The roof frame f7 consists cfa pair of stringers or principals h which, are bolted together at their ends and centrally disposed between which is fastened a base block 2l set in a mortise in which is the foot? or Patented July 18, 1911.
Serial No. 616,293.
ten'on, of the crown-post j. Fastened to the stringere or principals L of the roof frame are the inner ends of the purlins 7c, which extend outwardly in a radial direction. 1 iT he vouter ends lof the purlins /c and the principals la. rest loosely in kerfs or gains c, h formed in the upper end of`the cylindrical wall -of the silo. The lower endsl of the .rafters m'a/re fastened to the outer ends of the purlins 7c, while the upper ends of the rafters m are fastened to the top of the crown-post the roofboards n in the usual manner. The roof boards n maly be covered with shingles o or any felt or composition roofing. No
fastening devices are used to bind the horizontal members of th roof frame to the cy. lindrical wall of the'ilo; but the roof fra-me is held in place thereon merely by its weight. .ills the hoops are tightened or loosened and the cylindrical wall' is thereby contracted or allowed to expand, there is a slight rela' tive movement of the outer ends of the horizontal frame membersof the ro'of in the kerfs or gains t, c.
lt is obvious that the roof hereinbefore described will protect the contents of the silo from the elements and at the Sametime will not interfere with thetightening or the loosening of the hoops or bands, as the stavef formed cylindrical wall contracts or eX- pands.
To claim:
l. A roofed structure of the character de-` scribed having a body portion of staves formed at its upper end with notches; and a roof frame the members of which are slidably mounted in said notches and thereby permit the free inward and outward move- 'ment of theupper ends of said staves as the body portion contracts and expands.
2. A roofed structure of the character described having al body portion of staves formed at its upper end with notches; roofframe members which are slidably mounted in said notches and thereby permit the free inward and outward movement of the upper ends of said st-aVes as the body portion conrlo the rafters m are nailed tracts and expands; and means which eon trol the degree of said inward and outward movement of the upper ends of said staves.
3. A roofed silo the stave-formed body of which is formed with notches in which rest siidahly the hori'Lont-al frame members of the roof; the upper end of the body being free to contract and expand and to move relatively to said frame members in doing so.
day of March, A. I). 1911, in the presence of the tivo undersigned witnesses.
