ELIAS MORTIMER WILSON, 0F ANIlERSON, INDIANA, ASSIGNOR TO THE INDIANA SILO COMPANY,

OF ANDERSON, INDIANA, A CORPORATION OF INDIANA.

SILO.

To all whom it may concern:

Be it known that LELIAS MORTIMER VIL- sox, of Anderson, county of Madison, and State of Indiana, have invented acertain new and useful Silo; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

T he object of this invention is to improve the construction of silos.

One feature of the invention consists in forming the silo of vertically disposed planks, boards or pieces of timber which are in sections and the sections are jointed so that water from the material in the silo and otherwise will not enter the joint but will flow down the wall of the silo past the joint.

The purpose of this improvement is to preserve and prolong the life of the timbers at the joints, which is a matter of very great iniportance in the construction of silos. To that end said joint consists of arounded bead centrally located on the upper end of the board or plank with a surface sloping downwardly from each side thereof, and the provision on the adjacent end of the plank above of a groove to receive said head snugly and with a surface sloping downwardly from each side thereof so that the upper end of the lower plank will fit tightly within the recess formed in the lower end of the plank above it. Since all the surfaces at the upper end of the upper plank slope down- 'ardly, water will not enter the joint because to do so it will have to flow upwardly, whereas, with horizontal surfaces or the like 'on the upper end'of the lower plank the water would flow into the joint and remain there and soon cause the decay of the timber. Since there are: so many such joints in a silo and the material in a silo contains much moisture, the life of the silo will be very much prolonged by this improvement.

Another feature of this invention consists in providing means for clamping the doors of the silo in place soas to be readily removable and to serve as steps for climbing up the side of the silo. These two func tions result from pivoting to the door the ends of the loop-like rod or bar, the middle portion of which adapted to projectoutwardly some distance from the door to form a ladder and said means being provided near Specification of Letters Patent.

each end thereof with a curved cam-like surface adapted toengage stationary pins projecting from the sides of the door casing so that as said metal loops are turned from a vertical down to a horizontal position they will clamp the door partly in position and remain in a rigid horizontal. position for ladder purposes. At the same time the ends of ,said metal loop do not extend beyond the sides of the door so that by turning the metal loop to its vertical position the door can be readily removed from its opening inwardly.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims:.

In the drawings Figure 1 is a side elevation of the silo, showing the upper doors re- .moved, the lower doors being in place.

Fig. 2 is a perspective view of a section of the door frame, one door being in place and one removed. Fig. 3 is an inside view of what is shown in Fig. Fig. l is a section on the line 4-4 of Fig. 1. Fig. 5 is a sec tion on the line of Fig. l. Fig. 6 is a central vertical section through the silo. Fig. 7 is an edge view of two planks, showing the joint. Fig. 8 is a perspective of what is shown in F g. 7 with the joint drawn apart.

In detail the drawings herein show a oylindrical silo. with the. side wall thereof formed of a number of boards 10 and 11. The edges of these boards are vertically provided with tongues and grooves whereby they are tightly joined attheir edges.

Since silos are high it is necessary that the boards 10 and 11 be connected by transverse joints, as shown in Figs. (5 and 7 and to pre vent these joints from receiving and holding water whereby they will soon decay, I pro vide a bead l2 centrally on the upper end of thelower board 10, said bead being oval or curved in cross section so that water will flow off the same and'from each side of said bead 12 there extends a downwardly inclined surface 13 so that the water will flow off said surfaces. The upper board ll has a central transverse groove 14 adapted to snugly receive the bead 12 andqa. downwardly inclined surface [5 extending from each side of said groove 14 mlapted to overlap the surfaces 13, as shown in Fig. 7.

\Vith the timbers forming the silo connectone silo.

ed at their ends by the joint described, water will not flow upwardly into the joint but the joint will be maintained substantially dry andthus greatly prolong the life of the 8110 because there are many oints and planks in The silo herein shown provided with "vertically dis osed' door casing formin a number of oor openings 21 one above the other separated by stationary intervenin wall portions 22. These openings are close by doors 23 that are'p'ut 1n place from the inside and fit against the ledges 24 of the cas=' ing and are clamped against said ledges by ,the loop-like or U-sh'aped rod or bar 25,-

turned from a'vertical to a horizontal position, engages pins 29 projecting inwardly from the ledges 24 of the door casing and, therefore, draw the door outwardly and clamp it against said ledges 24. When the door'is thus clamped, the rod or bar 25 is supported by the pins in a horizontal position so that it'serves as a step for use inclimbing up the side "of the silo. to get into the silo for pitching'out a ortion of the contents when the same is. desired to be used.

It is thus observed that the bar 25 and associated parts not only succeed-in clamping the doorand holding it closed, but serves for ladder purposes. I

What I claim as my invention, and desire to secure by Letters Patent is: p

1. A silo including a wall formed of verlower board at each joint tially disposed boards joined with each other at their ends, the upper end of the iaving a central upwardly extending bead curved downwardly in cross section and a surface sloping downwardly from each side thereof, and the end of the upper board of each joint having a central groove to receive said bead, and

side. surfaces sloping downwardly from eachside thereof so as to fit snugly upon the corresponding surfaces of the board below, sub-- stantially as set forth.

2. A silo including a vertical door casing having a series of door oienings, doors for closing said openings, an means extending transversely of the door and connected at their ends to the sides of the door and the door casing for securing the doors in their closed positions and which project outwardly therefrom to form steps for climbing the silo.

3. A silo including a wall with a door casing and lodges thereon, a door fitting insaid casing and against the ledges, pins extending inwardly from the ledges, and a bar with its ends turned at thright angle to the body- 1h ereof and )ivoted to said door between the sides thereo and said end portions being bent to form a curved surface for engaging said pins and resting'upon said pins whereby the door will be clamped in place when the bar is turned to a horizontal position and the bar will serve as a ladder and when turned in an upward position said bar will disengage the door from said pins and permit the ready removal of the door. In witness whereof, I have hereunto ailixed my signature in the presence of the witnesses herein named.
