GEORGE 1 BRUBAKER, 0F BERLIN,'PENNSYLVANIA.

SILO-DOOR.

To aid whom it may concern Be it known that I, GEORGE P. BRUBAKER, a citizen of the United States, residing at Berlin, in the county of Somerset and State of Pennsylvania, have invented a new and useful Silo-Door, of which the following is a specification.

x This invention. has reference to silo doors, and its object is to provide a door of simple construction which may be readily set in place and as readily removed with each door section sufliciently narrow to greatly facilitate the use of the silo.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings :Figure l is a front elevation of a portion of .a silo showing the doors in place and one door jamb broken away to disclose a retaining bolt or rod. Fig. 2 is a section on the line 22 of Fig.1. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig. 4; is a section on the line 1-4 of Fig. 1.

Referring to the drawings there is shown a small portion of the walls of a silo 1 without any attempt to show the construction of the walls, and on opposite sides of a door opening provided in the silo are upright door jambs 2, 3, respectively. The janib 2 is provided with a longitudinal groove 4L and the jamb 3 is provided with a longitudinal bevel face 5 opposite the groove 4;. The groove 4 and bevel 5 are located on those faces of the jambs directed toward each other, and are adjacent to the inner walls of the jambs. At the bottom of the door opening is a sill 6 and adapted to the other end of the door opening or to intermediate points, if desired, is a lintel 7, while adjacent to the lintel 7, or to each lintel 7 where more than one is employed, the door-opening is traversed by a rod or bolt 8 extending through the jambs and held Specification of Letters Patent.

in place by nuts 9. This bolt is removed after the silo is erected and the doors are put in place.

Adapted to the door opening are doors 10 each having at one end a rabbet producing a tongue 11 adapted to the groove 4, while the other end of the door is beveled, as shown at '12, in conformity with the bevel 5 of the jamb 3. That end of the bevel 5 remote from the interior of the silo and corresponding to about half the thickness of the ja1nb 3 terminates in a shoulder 13 against which the corresponding portion of the beveled end 12 of each door section may abut. The door sections are all relatively narrow and at the top and bottom edges these doors are formed with rabbets producing tongues 14 and 15, respectively, located on respectively opposite sides of the top and bottom edges.

For the topmost portion of the door opening there is provided a door section 10 corresponding to the door sections 10, eX- cept that it is provided with top and bottom tongues 14? and 15 on the same side of the respective top and bottom edges of the door section. For the tongue 15 of the lowermost door section the sill 6 has on its lnner face a rabbet 16 of a size to receive the tongue 15 and for the tongue 14 of the door section 1O the lintel 7 is provided with size to receive said tongue 14 Adjacent to the bevel edge 12 of each door section said section is traversed by a bolt 18 having its threaded end extending beyond the face of the door which in use constitutes the outer face. Applied to the threaded end of the bolts is a wing nut 19. Each bolt 18 also traverses an elongated slot 20 arranged longitudinally of a latch plate 21 having one end 22 bent at an angle to the length of the latch plate and terminating in a nose 23 bent at an angle to the end 22- and in oil"- set substantially parallel relation to the body of the plate 21. The angle end is of sufficient length to offset the nose 23 from the body of the plate a distance suflicient to perinit the nose 23 to engage the outer face of the jamb 3 with the plate 21 close to the door 10 or 10, as the case mav be. Then on tightening the nut 19 the plate 21 and door 10 or 10 are forced one toward the other with the nose 23 engaging the outer face of the ..jamb 2 as a pivot. 19 may be loosened and then the door may the slot 20 permits the plate to be moved' lengthwise of the bolt 18 a suflicient distance tocause the nose 23 to be out of engaging relation to the jamb 3, whereupon the door section may be swung into the silo about the Instead of thisthe nut be lifted provided there be space enough above the door for the purpose.

The tongues 14 and 15 of the meeting edges of two doors interengage in a'manner to produce a tight joint because of the tortuous path produced by the overlapping of i the two tongues.

Each door sect1on is quite narrow with respect to its length, whereby the removal of the contents of the silo is greatly facilitated.

By making the door sections narrow the liability of warping or loosening due to air conditlons or chmatic changes is reduced to ,a minimum. The llntel 7 1s or may be as wlde as the jambs 2, 3, and has at one end a tongue 7 adapted to the groove 4. The other end of the lintel is formed with reverse bevels 7 and 7 entering said end of the lintel and displaced to produce a shoulder 7 The bevels 7 and 7 and the shoulder 7 d conform to the bevel 5, another bevel-5 and the shoulder 13 of the jamb 3. The lintel, therefore, is slidable lengthwise of the dooropening and compensates for any expansion or contraction of the doors due to the effect of climatic or other changes or conditions.

The simplicity of construction of the doors greatly reduces the cost of silos to the users.

eled faces of the jambs, and a door consisting of a plurality of sections between the sill and lintel, but of less thickness, each section having its end edges shaped to en- I gage the grooved and beveled inner faces of the jambs and having a top and a bottom rabbet providing a top and. bottom tongue, the tongues of the door sections entering corresponding rabbets of the door sections and of the sill and lintel, and a fastening device for each door section located at the beveled end of the door, the fastening devices and the tongues and rabbets coacting to cause each higher door section to prevent the removal of any lower door sect1on.

In testimony, thatI claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
