Specification of Letters Patent. Patented Sept. 24,1912.

Application filed Kay 27, 1911. Serial 110. 629,793.

To all whom it may concern:

Be it known thatI, JOHN" BonRUsoH, a citizen of the United States, residing at Maryville, in the county of Nodaway and and useful Improvements in Silos, of which the following is a specification. i

This invention relates to improvements in silos and has for its object to provide a door lock for silos which are placed with the doors, one above the other, from the bottom to the top of the silo.

A further object of the invention is to so construct the door and its frame that the door may expand or contract without binding, allowing the door to be easily opened at all times without the necessity of pounding it loose, the door being absolutely water tight.

In the accompanying drawings :-Figure 1 is an elevation illustrating the application of the invention to a silo.

silo, which are arranged in the frames 3, one above the other, as, shown in Fig. 1, 4 the door locks and 5 the hoops for reinforcing thdsilo, said hoops passing around the latter with their opposite ends threaded, as at 6, and extending through the castings 7. Nuts 8 are screwed on the projectin ends of the hoops and serve as a means or se- 4'0 uring the latter in place and for tightening *he hoops as occasion may necessitate. The doors 2 are provided at theirtop and at opposite side edges with'the one-

quarter moldlngs

9 and 10 which snugly fit in correspondi ing recesses in the cross pieces 11 and side pieces 12 of the frames. The bottom edges of the doors are beveled, as at 13,.and fit on the beveled or inclined upper edges 14 of the cross pieces, insuring a water tight joint. The doors are further provided at their top and-bottom edges'and also at opposite slde edges with the projecting flanges 1'5, which form a lap joint with the frames,

State of Missouri, have invented certain new Fig. 2 is a front, .elevation of one of the doors of the silo,

, cates the. silo, 2 the respective doors of the .fitting against the inner faces of the cross and side pieces thereof. By constructing the doors and the frames in this manner, it is evident that the doors are given a chance to expand or contract without binding, and may be opened without the necessity pounding the doors loose.

The flocks for the doors comprise the bolts 16 mounted to slide laterally in the keeper plates 17 attached by the screws'18 or other equivalent means to the cross pieces 19. The oute'r ends of the bolts are beveled, as at 20, to engage the outer inner edges of the side pieces of the frames. The lock for each door further comprises the U-shaped bail or foot piece, the legs 20 of which are pivoted, as at 21, between off-sets or ears 22 cast with the keeper plates 17; The pivoted ends'of the legs are provided with the reduced extensions 23 which work in the inclined slots 24 formed in the bolts 16. The central portion '25 ofeaoh bail forms a foot piece for the operator and constitutes one rung of a ladder.

In practice, the operator climbsto the point desired and opens a door by raising the hail from the dotted line position indicat'ed in Fig. 3 to the full line position which retracts the bolts 16 to the position shown in Fig. 2, when the door may be readily open d. To close the door the ball is swung down to the position shown in Fig. 1 which projects the bolts 16 into locking position- Particular attention-is invited to the fact that the bail is made in one piece, which makes it very strong and durable, whereas, it

would otherwise become weakened after a little use.

Fromtlie foregoing. description taken in connection with the drawings, it is thought that the construction and advantages of this invention will be readily understood without requiring a more extended explanation.

Having described my'invention, what I claim as new and desire to secure by Letters Patent, is 1 In a silo, the combination with the door frames, of a series of doors arranged one above the other in said frames, and door.
