CHAIN-MAKING APPARATUS. Y

Application led October 2'9, 1921. Serial No. 511,438.

To all whom 'it' may concern.'

Be it known'that I, JosnrH JOHNSON, a citizen lof the United States, residing at Lebanon, inthe county of Lebanon and State of Pennsylvania, have invented certain vnew and useful Improvements in Chain- Making Apparatus, of which the following is a specification.

One objectl of my invention is to provide improved apparatus for inserting studs in chain links such for example as in heavg7 chains where it is desired to reinforce and strengthen the links. i

Another object is to facilitate and expedite the insertion of'said vstuds and at the same time insure that the studs are properly secured in place.

These objects, and Y other advantageous ends which will be described hereinafter, l attain in the following manner, reference being had to the accompanying drawings Figure 3 isa view of the same general character as shown in Figure 2; the partshaving beenb operated to secure the stud in place, Y l

Figure d is a section taken on the line 4,-1 ofFigure 2, and f 4Figure 5 is a section taken on the line 5 5 of Figure,y 3.

Referring tothe drawings, 6 represents .abase lor.supporting structure which is preferably made exceptionally heavy4 and can be made out of'one or more blocks of metal. rlhe base hastwo `upwardly eX- tending parallel portions 7 whirh are spaced apart to provide a slideway for a plate 8; said plate resting on the top surface 9 of the lbase 6. The plate 8 adjacent one end has a transversely extending block 10 secured thereto adapted to serve as an abutment member for a die block'll .which is mounted on the top ofthe plate with its opposite ends in slidable engagement with the portions 7. A. second die block 12 has its opposite ends preferably secured to the rear` parts of the portions 7 and the opposed upright surfaces 13 and 111 ofthe die blocks 11 and 12 are 'concaved as clearly shown in Figures 2 and 3.

A stud supporting pedestal 15 issecured to the top of the base 6 and projects upward through a hole 16 in the, plate 8.l The upper surface of the pedestal 15 is grooved as shown at `17 ;V the groove extending from the front to the rear end ofthe pedestal and Y being preferably of a curved cross section so that when a stud, such as shown at 18, is positioned thereon, the groove will serve as 'a cradle for holding the stud in ahorizontal positionwith the ends of the stud art ranged in alignment with the sides 19Yof a link which is inserted between the concave .surfaces of the die blocks 11 and 12in a manner shownin Figures 1 and 2.V The base 6 has two upwardly projecting flanges 1 20 and between these 'flanges is4 pivotallyv mounted the lowerY end portion 21 of an actuating lever 22; the pivotal connection consisting of a pin 23-whichfextends through the flanges 20 and through the lower end of the lever. rlhe extreme lower end of the lever has a linger 24 adapted to engage .be-:

tween two lugs 25 and .26 on the plate 8 so that by rocking the lever 22, the plate 8 will be moved `backward and forward-be-L tween the .portions 7, and the die block 11 and part 10V will also receive said movement of the plate y8.

y .The upper surfe/e127 of :the lever 22 is preferably made convex inthe direction of f.

the length of the. lever 'so' that the lever wheny in the position shown in Figure 1 can `be moved downward either by the engage ment of al hammer, such as an automatic hammer, or a movable die member. when the lever 22 is swung downward from the position vshown inFigure 1 to the por sition shown in Figure, the die block 11 will be moved toward the die block 12 and Thus Y considering thata heated link has been laid flat in position on the plate `between the die blocks and .that a cold stud 18 has been positioned-on thepedestal 15 such movement Vwill cause the die block 11 to compress the sides of the link toward each other so that 1 the vsides of the link will `be forced into locking engagement with the"en'ds of the stud. i v

ln order to provide space for other linksv kcompressive action of the sides of the link which is receiving its stud. I also preferably provide the base 6 with an extension having a groove 31 providing a guiding channel forthe other attached 'links so that it i an easy mattei' to manipulate the chain so as to move each of the links successively between the dieblooks l1 and l2.

It will be noted that when the link is positioned between the die blocks that the pedstood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit Vmyself to the precise` construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come Y within the scope of the appended claims.

Having thus described'my invention, what I claim as new and desire to secure by Letters Patent is f l. Link stud inserting` apparatus includ-y ing a base; a movable and a fixed die block mounted on said base, and arranged for inserting a `chain link therebetween; means slidably mounted on said base and having means for engaging said movable die block; curved means for supporting a. stud inserted in said link; and a lever pivoted onsaid base and swingable to move said slidable means and' with it. the'lmovable die block to force the sides of said link into locking engagement with the ends of said stud; substantialf ly as'described.

2. Link stud inserting apparatus inclut- Vinlgfwabase providing a guideway; a memb er movable on said guideway; die blocks positioned above said member and providing a space into which a link can be inserted with a. stud. between opposed portions oi said link; and means for moving said member on its guideway, said member having a portion adapted to move one of said die blocks toward the other die block which is fixed with respect to said base in order to compress said portions of the link against the opposite portions of said` stud; substantially as described.

3. Linkstud inserting apparatus including a baseprovidng a guideway; a,plate slidable in said guideway; die blocks positioned above Vvsaid plateand providing a space into Vwhich a link; can be inserted with a stud between Vopposed portions ofl said linkgand -means for moving said plate in its guideway, said plate having a portion adapted to move Vone ofsaid die blocks toward the other to compresssaid portions of the link against the opposite portions of said stud; substantially as described.Y n 4:. Link stud inserting apparatus including a base providing a guideway.; a plate slidable 'in said guideway; die blocks positioned above said plate and providing a space into .which a link can be inserted with a stud between opposed portions of said link; and a pivotal'ly mounted lever, said plate having lugs spaced apart between which a'portion-of the lever engages whereby when the lever is swung the plate will be moved in its guideway; substantially as described.

5. Link stud inserting apparatus includvplate and spacedapart to allow a link tov be inserted therebetween; and means for moving said plate whereby the die blocks will `be relatively Amoved toward each other to Yforce the opposed portions of said link into Contact with the stud while on the pedestal; substantially as described.

6. Link stud inserting apparatus includ# ing a base; a stud supporting pedestal on said base; a plateslidable on said' base and having a hole through which said-.pedestal extends; die blocks positioned above said plate and spaced apart to allow a link to be inserted therebetween, one of said die blocks being liXed with respect to said base and the other being movable with saidplate ;.and A means for moving said plate whereby the die blocks will be moved toward each other to torce the opposed portions of said link on to the end ot said stud, said means including` a swingable lever for engaging and i operating said plate; scribed.

ln testimony whereof I have signed my name to this specification in` the presence ot two subscribing witnesses.
