SPECIFICATION forming part of Letters Patent N o. 735,485, dated August 4, 190.3.

Application filed May 6, 1902.

T all whom, it may concern:

Be it known that I, JOHN FAREELL, a citi-` maintained between the door-sections and` door-jambs or guide-posts, as well as between adjacent door-sections.

In the accompanying drawings, Figure l is 'a front elevation of a silo embodying my improvements. Fig. 2 is a horizontal section taken through the doorway of the silo. Fig. 3 is a View showing the device for clamping adjacent door-sections together. Figs. 4 and 5 are detail views of said clamping devices.

Fig. 6 is an end view of a door-section with a movable guard attached thereto, the latter being partly broken away; and Fig. 7 is a side view of the same.

` Referring to the drawings, a. indicates the silo, comprising a cylindrical wall 1, preferably made of suitably tongue-and-grooved staves or boards, retained in position against internal pressure by a suitable number of metal hoops or bands 2, and having aroof 3,

provided with a hinged door 4. Guide-posts or jambs 5 and 6 are arranged parallel with one another at either side of afdoorway 7, which extends from top to bottom of the cylindrical wall of the silo. The ends 2fL and 2b of each band are threaded and `extend through one of the guide-posts 6, said ends being adjustably secured tothe post by nuts;

provided with beveled faces 5l and 6, respectively, at the inner parts of their adjacent Serial No. 106.195. (No model.)

sides, and said beveled faces are provided with longitudinal grooves 12, substantially @semicircular in cross-section, within which .are arranged guide-ropes 13, said ropes be- ;ing suitably held within the grooves. These ropes, which are preferably braided and rendered waterproof, serve as guides for the sliding door-sections 14 and also serve the Vpurpose of packings between the door-sections and guide-posts.

The door consists of series of sections 14, `each having its lateral edges 15 beveled to ,correspond with the beveled faces: of the guide-posts or jambs and having semicircu- `lar groove 16 extendinglongitudinallyof said `beveled faces. The door-sections are placed `in position by sliding them down from the top 'of the doorway, the grooves 16 fitting around the exposed surfaces of the ropes and forming tongue-and-groove joints therewith. The door-sections are thus locked against inward movement by the ropes, which form 1guides for the sections. Grooves 17 and 18 are also formed in the top and bottom, respectively,ofeach door-section, and a rope 19 is arranged in one of said grooves. As shown in Figs. 6 and 7, the rope 19 is secured within the groove 17 at the top of a door-section and forms a tongue which is adapted to `fit within a groove 18 in the adjacent doorsection. The pressure of the materialwithin the silo forces the door-sections outward, compressing the ropes 13 within the grooves between the guide-posts and the door-sections, and thus preventing the circulation of air between the door-sections and posts. The adjacent door-sections are drawn firmly together by suitable clamping devices 20, thus compressing the rope packings 19 within the grooves at the ends of the sections.. Each door-section is provided with a stud or projection 2l and a clamping device 20, the clamping device being arranged to engage the projection upon the adjacent door-section. As shown in the drawings, the clamping devices 20 are arranged near 'the lower edge of each door-section and engage projections arranged near the upper edge of the adjacent sections. Each clamping device consists of a latch 22, having a hooked or turned-over end 23, which engages the catch or stud 2l,

and a lever 24, secured by a pivot 25 to the ICO door-section and having an eccentric projection 26, which fits within a circular opening 27 in the latch, the arrangement being such that when the handle is raised from the horizontal position the latch will be lowered out of engagement with the catch and when t'ne lever is turned into the horizontal position the latch will be brought into engagement with the catch or projection on the adjacent door-section,and the two sections will be drawn firmly together, compressing the rope packing 19 and making a practically air-tight joint.

In practice when apart of the ensilage has been removed from the silo one or more of the uppermost door-sections may be removed, and the next remaining section, such as t-he section 14d, is then slid upwardly on the guideropes and secured to the part 11 of the uppermost band by suitable means, such as the hooks 28. As fast as the material is removed -froin the silo thereafter the succeeding doorsections 14e lif, &c., may be moved upward and suspended from the section 14 by connecting said sections together with the clam ping devices 20. In the drawings the three topmost sections have been removed and the sections 14d, 14e, 143, and 14g have been moved upwardly, leaving a space for. ingress and removal of materialequal in height kto three door-sections between the section 14g and the section 14h. When the ensilage is removed to the bottom of the section 14h, said section may then be moved upward and connected tothe section 14g. A doorway is thus provided at all times just above the top of the contents of -the silo, and the door-sections, with the exception of the uppermost ones, will always remain in position ready to be replaced by simplyl unlocking and lowering them.

I In order to prevent injury to the rope packings 16 while removing material from the silo or the grooves in case the packings are arranged at the bottoms of the door-sections, a sheet-metal guard 29 is provided, as shown in Figs. 6 and 7, said guard consisting of a plate having a central longitudinal rib 30, adapted to extend over the rope 19, and flanges 31, arranged to embrace the sides of the door-section. The guard is adapted to j be placed upon each door-section in succes- 1. In a silo, the combination with a building having a vertical doorway, of posts at the sides of said doorway, said posts having beveled faces at their inner sides, compressible guides extending longitudinally of and projecting outwardly from said faces', and a series of door-sections having beveled lateral edges and grooves in said edges adapted to receive the projecting portions of the guides.

2. In a silo, the combination with a build'- ing having a vertical doorway, of posts at the sides of said doorway, said posts having beveled faces at their inner sides and grooves extendinglongitudinally of said faces, compressible guides within said grooves and projecting outwardly beyond said faces, and a series of door-sections having beveled lateral edges and grooves in said edges adapted to receive the projecting portions of the guides.

3. In a silo, the combination with a building having a vertical doorway, of posts at the sides of said doorway, said posts having beveled faces at their inner sides and grooves extending longitudinally of said faces, ropes within said grooves and projecting outwardly beyond said faces, and a series of door-sections having beveled lateral edges and grooves in said edges adapted to receive the projecting portions of the ropes.

4. In a silo, the combination with a buildn ing having a vertical doorway, of guide-posts at the sides of said doorway, said posts having beveled faces at their inner sidesand grooves extending longitudinally of said faces,compressible guides within said grooves projecting outwardly beyond said faces, and
