IlwllRGVl-D MACHINE FR CUTTING THREADS 0N BOLTS.
'tlge Satanic wenn tu hi ilgra @tritata zttint mit uniting un nt tigt simu.
TO ALL WHOM IT MAY CONCERN: if 4 Be it known that I, FRANZIS SCHWEIZER, ofthe city, county, and State of NewYork, have invented a new and improved Machine for Cutting Threads on Bolts, Ste.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to a new machine, whereby screw-threads can be cut on two bolts, at the saine time7 without using more power` than would be requisite tovcut a thread on one bolt. The machine may be so constructed that two or morebars can vbe transformed into screws at the same time. The invention consists in doubling the apparatus generally used for the purpose of-cutting-a thread on one bolt; that is to say, I provide two dies and die stocks, which are secured to two horizontal shafts. The latter are connected by gcaring'in such a manner that they revolve in an opposite direction. The bolts or bars are held in two visos, and are fed to the dies as 'the dies are revolving in an oppositedirection; a thread` will be cut on one bolt while the other bolt is being released from its die, and vice versa. Thus l cut in this machine threads on two 'oi-more bolts, without using more power than is necessary to cut one bolt. Inthe accompanying drawings my invention is illustrated-M Figure Ilv being a side elevation of my improved machine, partly in section.
Figure 2 is a vertical cross-section of the same, taken on the line a: es, fig. 1.
Figure 3 is a plan. or top view of the same.
Figures 4 and 5 are detail sectional views, to be hereinafter referred to.
Similar .letters of reference indicate like parts. v
The table A, which is made of wood or any other suitable material, is supported by four or more legs, B On this table are arranged two upright frames C C, which are provided with suitable boxes for the support of the horizontal shafts D,E', and F. On each of the shafts D'and E is mounted a gearfwheel, D E. These mesh respectively into the pinions F and G. The pinion F is mounted on the driving-shaft F, to which motion is imparted by the pulleys H. The pinion Gr is driven by the pinion l5", and meshes into the gear-wheel E', as seen in fig. 2. By this gearing arrangement the shafts D and E are revolved in oppositedirections; that is to say, when the shaft D. moves in the direction -of the arrow 1, the shaft E moves in the direction of the arrow 2, :in d, 'alice versa, when D moves with arrow 3, then E moves with'arrow 4, (see iig. To the end of each shaft, D E, is arranged a die stock, I K, eachof them holding die or cutter, t These dies-will revolve in the same directions us the shaft to which they are secured.. Two sets of tracks, L M, are arranged on/the table on which the stocks N and O slide respectively. Each ofthese stocks is provided with a vise, in 'which the head of the bolt which is to be operated upon is held'. Or'if these bolts are provided with square heads, a correspending holder, e, is secured iu each sliding stock. The bolt is secured in the vise or holder c and fed to the revolving cutter by a lever, P, which is pivoted to the table A, between the stocks N and'O. The lever is provided with two arms, d and c, and by proving a handle,f, on the lever, either forwards or backwards, either the arin l or e is pressed against the corresponding sliding stock, and feeds the bolt which is held in the same to the revolving cutter. The lever P can be longitudinally adjusted on the table A, so as to feed longer or shorter belts to the cutters. An elastic rest, g, is arranged on each stock for the purpose of supporting the central portion of the bolt. It is made elastic by means of rubber or ether'suitable springs, L, which Support two concave metal plates, i, the latter forming a semicircular concave rest, as shown more particularly in lig. 5, which is a vertical cross-section through the rcstg, the plane on section being indicated by the line y y, fig.
l. The elastic rest is preferable, as it will adapt itself to inequalities-in the bolts. lf these bolts should,
however, he very accurately made, a rest, Z, which is represented in lfigs. 3 and 4, will be suicient. The rest .f/ (or Z) is attached to a bar, on, which slides loosely in the stock N or O, to which it may be secured.
The operation of the machine is as follows: A bolt is secured on the sliding stock N, andthe machine is put in mot-ion, so that the cutter a revolves in the direction of the arrow 3. The extremity of the bolt is brought in contact with the cutter by pressing the arm l on the level' P, 'against the stock N. The cutter, after it has begun to cut the thread on the bolt, will pull the bolt forward, without any more action on the lever P being required. As soon as thc thread is out completely onthis holt, another bolt is placed intot-he stock Q and fed by the firm e on the lever P to the cutter b. The' Vmotion of the machine is now 1-eve1'sed/so\tha.t the cutter b turns in the direction ofthe arrow 2,'-nnd the cutter a turns in thedirection with arrow 1,. Athread will then be out on the second bolt while the-first bolt will beturned out of the'eutter a; and then atnother bolt is placed into the stock N, the machine reversed again, and' so forth. Thus the machine is Valways operating on and Th/e/ number of the sliding stocks inishin'g two bolts while it actually only cuts n. tllreadon one bolt at a. time. V and cutters may be doubled, trebled, or multiplied-in such a. mannerthztt a. pair of bolts salwnys operated upon in the manner herein described.
What I claim as new, and desire to secure by LettersPntent, is l. The sliding stocks N and O, i-n combination'with the lever P, arranged relatively I, operatingas described for the purpose specified.
Z. I claim vthe adjustable lever P, which is provided with arms'dnnd e,
with the cutters a and substantially as and for the purpose herein shown und described.
3. I claim the elastic slidingrest g, and described made and operating substantially as and for the purpose herein shown FRANZIS SCHWEIZER.
