REPAIR LINK FOR CHAINS.
Specification of Letters Patent.
Patented Jan. 17, 1922.
Application filedApril 5, 1920, Serial No. 371,408. Renewed June 25, 1921. Serial No. 480,463.
T 0 (tZZ' whom it may concern:
Be it known that I, ADoLPH T. JoHNsoN, a citizen of the United States, residing at Turtle Lake, in the county of McLean and State of North Dakota, have invented cer tain new and useful Improvements in Repair Links for Chains, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to chains, and particularly to repair links therefor, that is, links which may be used to connect two detached sections of chain, either forthe purpose of joining two lengths of chain together, or connecting a chain which has become broken.
The general object of the invention is to provide a repair link of this character which is very simple in construction, maybe readily made and which may be readily engaged with the two ends of the chain, but when locked will not become disengaged therefrom. v
A further object of the invention is to provide a repair link formed of two elements, each element being formed of bent wire, one of the elements constituting a double hook, as it may be termed, and the other element constituting a keeper, which may be opened or closed and when, when closed, has locking engagement with the main element so as to provide a thoroughly strong link, which will connect the two ends of the chain together.
Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my improved repair link;
Fig. 2 is a top plan view thereof;
Fig. 3 is a side elevation showing the link opened;
Fig. 1 is a perspective view of the link.
Referring to these figures, it will be seen that my improved chain repair link consists of a main element best illustrated in Fig. 4;, consisting of a length of wire 10 bent at one end to form an eye 11. The length of wire is deflected at 12 and then longitudinally extended, then bent to form a hook-shaped loop 13, then again longitudinally extended and laterally deflected across the portion 12 as at 1 1, then longitudinally extended as at 15 and then inwardly deflected again as at 16, this portion 16 at its extremity being angular-1y bent to form a nose 17. The other element of the link consists of a lengthof wire 18 bent at one end to form an eye 19, which is loosely engaged with the eye 11, the wire being then bent to form an open loop 20, then longitudinally extended and laterally bent as at 21, the extremity of this portion 21 being formed with a perforation 22. It will be noted that the hook- shaped portions 13 and 13 are formed by bending the material of the element 10 to form a loop, the bight of which constitutes the eye'12.
The eye 19 is loosely engaged for swingmg movement with the body 10 and when the keeper 18 is in its operative engagement with the body 10, the angular extremity 21 is passed through the eye 12 of the looped hook 13 and through the space between the portions 12 and 14 of the body as illustrated in Fig. 1, while the nose 17 of the portion 16 of the body is engaged over the looped portion 20 of the keeper. A pin, as for instance a cotter pin 23, is passed through the perforation 22, this pin having a head at one end and being split at the other so that it may be opened out to prevent the accidental detachment of the pin from its position. This pin, of course,.locks the keeper in its applied position and prevents the accidental withdrawal of the keeper from its engagement with the eye 12. It will be noted that the portions 12 and 14 are so formed as to provide an eye corresponding to the eye 12 and through which the keeper passes.
In the practical use of this device, when it is desired to connect two lengths of chain, one of the links A for instance of one length of chain is engaged by the hook-shaped loop 13. The link B of the opposite length of chain is engaged with the angular portion 16 of the body and then the keeper is swung over the portion 16 of the body until the extremity 21 of the keeper passes through the eye 12 and between the portions 12 and 14. The pin 23 is then passed through the perforation 22 and the link is locked in place. It will be seen that the pull of the connected chains acts upon the relatively strong hook formed by the parts 13. 13 and the loop 12 and that the pull of the other section of chain comes upon the angular bend 16 and that the link formed by the member 16 cannot bend open because of the fact that the nose 17 is engaged with the cheaply made by machinery, is very simple,
requires a relatively small amount of wire to term 1t, and it is thoroughly effective in practice and is as strong as the original chain. The device may be used iorrepairing all kinds ofchains and it is particularly useful in connecting the broken links of tire chains or chains of likc character.
llaving described my invention, what I claim is: I i
l. A repair link comprising two elements, I
one element bent to form a hook and a hookshaped open link disposed in planes at right angles to each other, the other element forming a keeper swingingly engaged with the first-named element, bent to engage over the extremity'ol the-hook-shaped open link and having its extremity formed to extend transversely across said first-na1ned hooked portion and to interlock therewith.-
2. A repair link comprising two elements, one or said elements being formed of wire bent at one end to form an eye, then longitudinally extending and deflected in the planeof said eye, then longitudinally extended and laterally bent to form an open loop in aplane at right angles to the plane of the eye, then bent in aplane parallel to the plane of the eye and then curved approximately parallel to said loop to thereby form a loop shaped hook, then extending across the firstnamed deflected portion of the wire and longitudinally. extended and then angularly bent in a plane parallel to the plane of said eye and having an angular nose formed on its extremity, a second element forming a keeper,said second ele ment being formed'of wire bent at one-end to form an eye engaging with the first-named eye, then bent to form an open loop engageable behind said nose, then longitudinally extended, then laterallybent to pass through the hook-shaped eye and between the portion parallel to and opposite said eye, the extremity of said angular portion of the keeper being perforated, and a locking pin passing through said perforation but detachable therefrom. l
3. Arepair link comprising two elements, one of the elements bein bent to form parallel registering hook-shaped portions, an eye and an open hook-shaped link extending away from the hook-shaped portions, a keeper swingingly engaged with said eye and bent to engage over one end of the open link and extend across the opening thereof and across the opening of the hook-shaped portions when the link is in one position, and means for locking the keeper in said position closing said link andthe hookshaped portions.
4. A repair link comprising two elements, one element bent to form a hook-shaped loop, an open link extending away from said hook-shaped loop, an eye adjacent the juncture between the hook-shaped loop and the link, the other element forming a keeper swingingly engaged with said eye and bent' upon itself to engage over the extremity of the link remotefrom the hook-shaped loop, said keeperat its end being angularly bent to extend through the bight of theloop and across the opening of the hook formed by the loop, and means for locking the keeper in the last named position.
In testimony whereof l hereunto afiix my signature.
