To all whom it may concern 5;.
Beit known that I, JosnrH Mnnnrr'r, a
citizen of the United/States,residing at Hartford,1 in the countyof Hartford and State of Connecticut, have invented anew and useful Improvement in Ring-Straights ening Mechanism, of which the following is a specification. l
It is common practice in the art of male, mg rings in largeuquantities to wmd'the wire or tube from which theyzaremajde into a spiral co l and then cut the coil along one side. This, l1owever,'leaves the rings twist ed spirally so that the ends of each ring are not opposite one'another. a p The present invention relates to a mecha- 'nism which is designed to receive a coil of wire or tube and hold it while it is be ng cut along one side for the purpose of sepa rating the turns of the coils and formingthe" rings. The object of manner while it is bein cut alon one side a the out has been made in such manner as to posite direction.
simultaneously straighten, all the rings, that is, twist them sons to bring the ends of the rings opposite eachother.
Iii carrying out this invention there is a holder with a recess adapted to. receive: the coil or" stock from which'the rings are to be formed. There is a fixedrack with teeth which project intoflthe recess on one side, and twomovable racks withteeth that project into the recess on the opposite side The movable racks are separate'dso as to' allow a saw to rotate betweenthem for cutting the coil. Theracks are first in such relation that when the coil is placedi-n the recess the rack teeth will extend between the turns after the manner of a screwthread, and then after the saw has made itscut, one movable rack is forced in one'direction, and the other movable rack is forced in the op- The teeth of 'the' racks moved in this way simultaneously and unithis invention is toprovide a simple and easily operated mechanlsm of this class which holds 160011 in adesired formly carry thesevered ends of the'rings so that the" endsof each ring willbe alined. Figure I of the accompanying drawings shows a* plan of mechanism which-embodies the invention with the partsin the positions occupied :when. the. spiral coil is first placed I straightenthe rings." Fig. .3 is a view 'ofa sectionof the magazine barwith a few rings. Th s :bar is employed for holding the rings while they areubein'gstraightened; and it provides means whereby all of tlierings' may be removed together in condition to be fed 111130 another machine for subsequent manipulation. Fig.4 shows a plan on larger" scale of a short piece of coil-severed 'for forming the ringse Fig. 5 shows aside view of the same with the magazine bar in place.

The holder which is illustrated is formed of two members 1, 2', which are detachably held together by dowelpins 3 Nearthe upper edges in the inside faces of these members ofthe holder are longitudinally extending curved grooves-4; 5. When these two members of the-holder are put together, these grooves form the recess in which the; coil 6'is" placed and clamped. Secured to the inner face of one member ofthe holder,
preferably'to the member 2 by screws 7 is a plate 8 which has a rack on its upper edge.
I The teeth 9 of this rack project into thebottom ofthe coil recess; 1
lvlovaloly secured'on the top of th'e holder member is a slide 10. t 7 passing through slots l2 hold this slide in place and guide it'when it is moved. Mov-' ably secured to the top of the holdenmeme her 21s aslide 13 that is held by screw studs l l that passthrough slots These slides are 'spaceddistance apart; approximately equal to the thickness ofthe cutting-sawl6 i case; on the otherside of the saw.
whichis mountedon the arbor. 17 and which when the. cut" is being made. extends down ,between the slideswfinto' therecess. On. the edge of, the slide 10 is a rack with teeth 18 that project into the 'recess'on one side of the saw, and on the 'edgegof the slide 131s a rack. with teeth 19; that. project 7 into Fastened: to the opposite ends of each of the'members of the holder is a bracket20, and turning in eachbracket is a screw 21.
' These screws may. beprovided with clamp "enter-between the turns of the coil in th c .m'anner of screw threads. When the C0ll 1s 'nuts'22 if desired. i ":The'screws, maybe .ltu rned against opposite endsof the slides, for holding-the slides in position and for moving them longitudinally with relation to eachother and to the holder.
The spirally 1 coiled wire ortube from i which the rings are to be formed is located in the recess,;the slides being adjusted so I that the teeth of :the racks which-they carry in place and isheld by therack teeth, either i the holder is moved beneath the saw, or the sawjis moved along theholderas desired for cutting thecoil along one edge between the' two..movable racks and severing the turns into independentjrings 23., After this out has been madeby'the saws or other suitable means, one of theslides may be forced 1n one direction andthe'other' slide may be vforcecllin the opposite direction. As the fixed rack holds the rings near the middle on "one side-o1": the recess and the two movabler'acks engage the rings at their ends on the other side of the recess this movement twists all of the rings and straightens them from the shapefshown in Fig. 6, to the shape shown in Fig. 7, in which the ends are in a-linement with each other. For the pur pose of retaining 'therings, a-rod 24c with a feather 25 may be thrust intothe recess, the rod passing inside of e the rings and the feather-between the ends. The rod andfeather are desirably insertedinto the rings just after the saw has made the cut and be fore the rings are'straightened so that when they'are twisted for straightening they will Stud screws 1l' the re- I slide.
not A collapse or have their ends jammed to gether. This'rod and feathermay also be conveniently employed for. removing the ringsall at one time insuchspositi'on that theycan be conveniently fed to another machine for subsequent operation. After the rings have'been straightened, the two members of the holder'are separated,allowing the rin-gs to be taken out strung on the rod.
The invention claimed is:
1. A ring straightening mechanism hav- .7 5 y i ing holder with a recess adapted to re-:
'ceivea coil "of stock, a fixed rack projecting into said recess; and adapted to, engage theturns of the coil on one side, two racks with 'a saw space between them pr'ojectingfinto saidarecessfand adapted to engage the turns of the coil' onth'e opposite side," ;and means for moving said lastmentionedracks longif tudinally with relation to each otherand to saidfixed rack forstraightening the, rings.
