NUT-LOCK.
SPECIFICATION forming part of Letters Patent No. 594,153, dated November 23, 1897.
Appiaaaon inea :rune 28,1897. saturo. 642,640. cromada.)
To @ZZ whom it may concern:
Be it known that I, JOHN A. GscHwENDER, of Martins Ferry, inthe county of Belmont and State of Ohio, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare the following to be afull, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to nut-locks.
The object of my invention is to produce a device of the character above mentioned that will be simple in construction, cheap, and efficient in operation.
I am enabled to accomplish the object of my invention by the simple means illustrated in the accompanying drawings, in which- Figure l is a perspective view of the bolt with a key and nutremoved therefrom. Fig. 2 is a perspective of the key adapted to enter the inclined recess in the threaded end of the bolt. Fig. 3 is a central longitudinal section of the bolt-nut and means for locking the same. Fig. 4 is a perspective view of a portion of the locking means.
Referring to the drawings, the numeral 1 indicates the bolt, which is provided with an ordinary head 2.
The numeral 3 indicates a recess made in the end of the bolt for the reception of a wedge-shaped key 3', which has its upper edge screw-threaded to form continuations of the screw-threads et on the end of the bolt. The recess in the end of the bolt is inclined downwardly from the end of said bolt to a v point preferably about a half-inch from the point where the threads upon the bolt terminate, so that when the nut is screwed onto said bolt it will have a bearing upon the solid portion of the bolt, lessening the liability of the bolt to become broken.
The key has an inclined bottom edge which is adapted to fit in the inclined recess in the bolt, and said key is also provided with a small head 5, which is adapted to engage with notches 6 on a lock 7 which, when the wedgeshaped key is in the recess in the bolt, is positioned on the end of the bolt after the nut and key have been put in place and the nut moved to the desired point upon the bolt.
The lock 7 is, as shown in Fig. 4, provided with a spirally-inclined face which is notched to form short shoulders parallel to the face of the nut, so that there will be no tendency to loosen on the bolt. After the nut has been placed upon the bolt and the key put in position in the recess the lock is then put on over the recess and turned until the spirally-inclined face on the lock comes in contact with the head of said key,` when the lock is turned and tightened to the desired extent, meanwhile drawing the key' in close contact with the bore of the nut, thus preventing the same from being turned.
Having thus described the invention, what is claimed as new is l. In a device of the character described,
the combination with a bolt having an inclined recess in the screw-threaded portion thereof, and an inclined wedge or key provided with a head on its outer end and adapted to enter said recess, a lock formed with the spirally-inclined face with notches thereon and adapted to be turned upon the bolt, the spirally-inclined face of said lock being adapted to be brought in contact with the head on the wedge or lock, thereby drawing said wedge in close contact with the nut when said lock is turned to prevent the nut from turning on the bolt, substantially as and for the purpose set forth.
2. In a device of the character described,
the combination with a bolt having an inclined recess in the screw-threaded portion thereof, an inclined wedge or key provided with a head on its outer end and threads on its upperside and adapted to enterthe recess, a lock formed with a spirally-inclined face with notches thereon and adapted to be turned upon the bolt and upon the wedge, thereby drawing said wedge in closer contact with the nut and preventing the same from turning, substantially as and for the purpose set forth. In testimony whereof I have signed this specification in the presence of two subscrib# ing witnesses.

WM. H. FISHER, GEO. A. MILLER.
