WILLIAM O. BERRY, 012" CARD, IMICHIGAILJ.
LOCKING ATTACHMENT.
Application filed September 22,1922. semi No. 590,127.
To all whom it may concern.
Be it known that I, WViLLIAM O. BERRY, a citizen of the United States of America, and a resident of Caro, in the county of Tuscola and State of Michigan, have inventedcertain new and useful Improvements in Locking Attachments, of which the following is a specification.
My invention relates to a iocking attachment for bolts and the like.
One object of the invention is to provide a novel locking attachment for securely locking a bolt in position when in place.
Another object of the invention is to pro vide a very simple and inexpensive locking attachment, which can be easily manufactured and which does not necessitate the bolt proper being made longer to provide for its attachment.
A further object is to provide a locking bolt which when inserted in position for which it is designed will prevent vertical movement of the bolt as well as looking it in position.
WVith the above and other objects in view,
the present invention consists in the oombi-,
nation and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size and proportion of the different parts, without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing.
Fig. 1 is a side View illustrating my improved locking bolt in locked position in a conventional clevis.
Fig. 3 is a side view similar to Fig. 2, but showing the end of the key proper.
Fig. i is an isometric view of the key.
Referring particularly now to the drawing in which I have shown the preferred embodiment of my invention, the numeral 1 indicates a conventional clevis having the usual bolt receiving openings formed therein in spaced relation, and through which the bolt 2 is adapted to be inserted, and while in the present instance I have shown the bolt used in connection with a clevis, it will be clearly understood that it can be used in any position where it is advantageous and desirable to lock the bolt in position.
The bolt 2' is provided with the usual squared head 3, the lower end being split as clearly shown at 4': to form a pair of forks 5. A flat key member 6 is adapted to be secured between the forks 5 by means of a rivet member 7, the rivet openings in the forks being countersunk as clearly shown, so that the body of the bolt will present a smooth surface and can be readily inserted in the openings for which it is intended.
One end of the key is formed with a rounded end 6 while the opposite end is formed with a blunt point 6 so that it can be easily guided into openings when in its unlocked position as clearly shown by dotted lines'in Fig. 2 of the drawing. I
A slotted opening 8 is formed in one end of this key member 6, the rivet 7 extending therethrough and serves to loosely secupe the key between the forked ends of the bo t.
A locking ring 9 is adapted to hold the key in locked position and is formed identically similar to the conventional key ring in general use, this is secured in the slotted opening when the key is in locked position and prevents the key moving longitudinally a distance sufficient to allow it to drop to vertical position.
In practice the key is dropped to vertic cal position and the bolt is inserted in the opening, the pointed end of the key is then swung upwardly to horizontal position and shifted horizontally until the end of the slot engages the rivet, the slot is then sufficiently exposed to permit the attaching of the locking ring, thereby locking the bolt against removal.
I wish to direct particular attention to the fact that the key when in locked position can fit snugly against the underside of the clevis, thereby preventing chucking and saving on the stock in the manufacture. This construction lends itself to quantity production and there are no springs or other small in trioate parts to'stick or wedge.
From the foregoing description it will be obvious that I have perfected a very simple and efficient locking attachment for bolts and the like.
WhatI claim is y 1. The combination with a bolt having a forked end, of a key having an elongated slot in one end thereof and a rivet passing through said slot and connecting the bifurcations of the fork, said slot permitting longitudinal movement of the key to allow it to drop to vertical position, and means ,en-
gaging the slot when the key is in locked posi-- tion for preventing movement thereof to the unlocked position. v
2. The combination with a bolt having a forked end, of a key formed with pointed and rounded ends respectively and having an elongated slot in oneend thereof and a rivet passing through said slot and connecting the bifurcations of the fork, said slot permitting longitudinal movement of the key to allow it to drop to vertical position, and a detachable ring engaging the slot when the key is in locked position for preventing movement thereof to the unlocked position.
In testimony whereof I have fixed my signature. I
WILLIAM O. BERRY.
