v i Specification of Iletters Patent.

Application filed January 8, 1906. Serial No. 295.024.

To all whom, it may concern:

Be it known that I, ARTHUR O. HUBBARD, of Minneapolis, Hennepin county, Minne sota, have invented certain new and useful Improvements in Silos, of which the followv ing is a specification.

The object of my invention is to provide a silo having air tight walls and one in which there will be no danger of the formation of mold on the inside of the silo while it is in use.

The invention consists generally in a silo composed of vertical panels, of suitable length, having inner and outerwalls witn a space between them, and means for binding the panels together.

Further, the invention consists in providing interlocking tongues in the joints between the panels,.and

Further, the invention consists in various constructions and combination, all as hereinafter described and particularly pointed-out in the claims.

In the accompanying drawings formingv part of this specification. Figure 1 is aside elevation partially in section of the lower portion of. a silo embodying my invention. Fig. 2 is a partial horizontal section of the same. Fig. 3 is a detailview showing several of the panels in' elevation, and the means for locking their abutting edges together.

- door panel.

Fig. 4 is a horizontal sectional view showing. the tongue between the abutting edges of the series of matched pieces of timber 4, between i which bars 5 are vertically arranged, separating the inner and outer walls and forming an air space between them. "The ends of the boards are beveled, as shown in Fig. 5, to allow the vertical edges of the abutting panels to be fitted snugly together and conform to the circular shape of the silo. The bars 5 are of suitable thickness to form an air space of the desired area between the panels, and the nails) to t matched pieces are fastened securely (as b c barsan d form sections or pane s l i i tion for the Patented May 14, 1907.

of any suitable length, preferably about six or eight feet, as that size has been found most convenient for handling. The panels are arranged vertically onthe-base, and into the space between the .abuttingends of each pair a vertically arranged tongue Gis inserted, being slightly concave 'on one side and ,con-

vex on the other, to fit the curve of the joint.

The ends of the panels and the tongue are ill.- rangedto break joint wit-h one another, as indicated in Fig. 3. When the tongue 6 has been inserted between the joints the panels will be held in their proper relative position,

and any air entering the joint will be compelled to follow a tortuous path from the inner to the outer wall of the panel; and where the oint is well made and the tongue fitted snugly there will be so many turns and Cor- I ners that it will be practically impossible for .the air to pass through the joint into the silo. The tongue may be integral with the bars 5 if preferred.

()n the outside of the silo I arrange a vertical studding 7 having its inner face concaved slightly to conform to the joint between the panels and fit in snugly against the same to brace the panels and hold them in proper relation with one another, and at the same time form a further covering or protectherethrough.

There are as many of these pieces of studjoint to prevent the air passing ding around the outside wall of the silo as there are vertical joints between the abutting ends of the panels One or more .of the panels is provided with a series of vertically arranged doors 8 located at intervals in the panel between the pieces of studding 10 -which have tongues or ribs 11 to fit between the inner and outer walls of the adjacent panels and rabbeted inner edges 12 to re- .ceive the vertical edges of the doors. Vertical strips 13 are provided on the doors vbetween the s'tudding 10 and the outer faces of said strips flush substantially with the corresponding faces of studding 10 and provided with suitable buttons 14 which lap said studding and locking the doors in place thereon. The pressure of the material on the doors will only serve to hold them more securely in the panel.

moved. At the top and bottom of each door I prefer to provide a top rail 15 and sill 15 ihaving tongues. 16 to enter the spaces As fast as. the silo is filled, the doors will be put in place and then as the silo is gradually emptied may be rebetween the -i iiner and outer walls of the panels and ,rabbet-ed inner edges 17 to-receive the ends of the. doors. The pieces of lumber of which the doors are composed are matched, asindicated in Fig. 8, and the vertical side strips are connected. by a cross forms a handle for use in opening or closing the door. The silo is inclosed by suitable hoops 19 which pass around the outside of the studding 7 and have suitable adjusting means 20 by means of which the hoops can be tightened orloosened. at will. These hoops may be" arranged at suitable intervals according to the size of the silo and the probable o'utward .pressure' to which the walls will be'subjeeted; A silo of this kind will be l simple inconstruction and comparativelyinexpensive to manufacture and having a dead air space between itsinner and outer walls will be impervious to moistureand will l positively prevent the collection of inold on the inner surface,- T Iiclaimas ny invention? 1. A silo composedof vertical psinelshaving inner and outer walls with 'af'space be tween them, and vertical tongues providedin ,zthe joints between the abutting panels, substantially as described.

2'. A silo ihaving walls composed'o fverti-'- cally -arranged panel sjhaving beveled abutting-edges fitting snugly together and composed of inner and; outerwalls with a space between them, and removable tongues fitting in'to aid space and uniting the abutting edgesof the panels;

. 3, ,A silo composedof 3a series of vertical panels each consisting of short horizontally arranged pieces of lumber having matched contigu'ous edges, and vertical'stri s separating-an inner'and outer'wall 'and orming an an space between them, and means for uniting' the vertical vedges ot' said pan and V I bar 18 which locking them securely together,

' Witnesses forming an air tight joint between them, substantially as described;

4. A circular silo composed of panels with vertical joints between them, vertical tongues connecting said p els in said joints and and said tongues being curved in crosssection to 0011- form to the curve of the silo substantially as described. j v

5. A silo composed ,of panels havingver tical joints between'them, and tongues fitting bet'weenthe edges of said panels and forming a tortuous joint through the same from one side of the wall to the-other, and studding arranged outside of said joints and concealing the same, and hoopsar'ranged to bind said studding and joints securely together. i

1 6. A silo composed of vertical panels havinginner and .outer walls-with .a space between them, vertical tongues rovided in the joint'between saidpanels an holding them in alinement with one another and ing the direct assage plreventof air through t e joint,

vertical stud ing provided outside SitldjOllll'f and concealingthe same, and hoops-binding saids'tuddingand joints together. v
