Letters Patent No. 104,234, dated fune 1d, 1870.
IMPROVED :DIE I'QIRV CUTTING- SCREW THREADS ON BOLTS.
l'To all l'u'fhomt may concern:
'peranccville, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Dies for Gut-ting Screws; and I do hereby declare that the followin -is -a full and exact description thereof; reference beinghad -to the accompanying drawings and to the letters of reference marked thereon.
The nature of my invention consists in the combination and arrangement of a stock, dies, regulatingnut, clamping-'ring and nut,l constructed, arranged, combined, and operatingl in the manner hereinafter described.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construc- 'tion and Operation.
In the accompanying drawings, which form part of' my specilcat-ion- Figure l is an end view of my improvement for cutting screw-threads On bolts.
Figure 2,-is a longitudinal section of the same, cut through atline :c Oi' tig. l.
In the drawings- A represents the stock, which is provided with three openings, marked t', for the receptionof the diesf, and an opening, h, for receiving the bolt on which the screw-threads are to be formed. The sides ofthe dies f should lit'close to the sides of the openings i, so as to -p1'eve1it..any side motion of the dies. The form of the cutting-dies are 'clearly shown in iig. 2, and provided with Ordinary cutters, as shown at n.
' The stock A is provided with screw-threads o, nut D, ring e, regulating-nut g, ilange B, and shank C.
The form andarraugemcnt of thevs'everal parts, and the relation that said parts bear to each other, will readily be seen audunderstood by theskillful mechnnic from the foregoing description and by reference to the accompanying drawings.
I will, therefore, proceed to describe the operation g5' y improvementfor cutting screw-threads on bolts,
c.. i The shank -G is placed in/the hollow mandrel ofthe lathe-head, and the flange B is bolted to the face-plate of the lathe by bolts placed in the openings o. I then adj ust the dies f to the diameter of the bolt by means of the regulating-nut g, which will, by screwing it forward On the stock A, open up the dies j; and, by turnin g it back, allow the dies to close together; Having adjusted the dies through the lating-nut g, I then secure them firmly b'y forcing the ring e against the back of the dies, vby turning the nut D, and thereby clamp them between the ringr e and regulating-nut g, as represented in lig. 2.
The manner Of cutting the screw-thread on the bolt will be readily suggested to the skillful mechanic, without further description.
From the foregoing description, and by reference tothe accompanying drawings, it will be observed that the dies are arranged for cutting only one size of bolt, but that, by giving to the front and back ends of the dies the same inclined angle, with corresponding inclinesiu the stock A, the mechanism used for oper- .atiug them will so move. them as to adapt them to cutting screw-threads on bolts of dilerent diameters. As I propose making this arrangement Of dies the subject Of another application for Letters Patent, I will not further describe them in this specification.
It will also be observed that, bythe arrangement of the dies and their working-mechanism, 'as herein described and represented in the accompanying drawings, my device is well adapted for holding, boring, and turning tools concentric to 'work to be done in turning or boring-lathes.
I wish it clearly understood that I do not claim, broadly, the use? Of graduating-dies in a screw-cutting machine.
Having thus described the nature, construction, and Operation of my improvement,
Y What I claim as of my invention is- The combination and arrangement of the stock A, dies f, nutsy 'and l), 'and ring e, constructed, a1- ranged, Vand operating.substantially as herein described and for the purpose'set' forth.
JAMES E. WEAVER.
