Be it known that LIVE. M. MAYO, of Cincinnati, in thecounty of Hamilton, and State of Ohio,'havo invented l certain new and useful vImprovements in. Machines for Cutting Screws on Bolts; and I do hereby declareithat` thefollowing is a full, clear, and exact description thereof, referenco being had to theaccompanying drawings, making part of this specification, and to the letters of referencemarked thereon, like lettersindicating like parts wherever they occur.` A i v To enable others skilled in the art to construct and use my invention, I will proceed to describe it.
My invention consists ina novel arrangement of devices for holding and operating the dies in machines for cutting screws on bolts, usually denominated bolt-cutters, and relates more especially to that class of boltcutters in which the blank is heldin a longitudinally Vmovable stock, while the cutting-dies are attached to and revolve with a.' hollow arbor or mandrel. f
Figure 1 is a side elevation of a machine with my improvements applied thereto. Figure 2 is a sido view, and i v'Figure 3 a top plan view -of my improved devices detached from the machine. V In the drawings, A represents the mandrel of a bolt-cutting machine, provided-with the pulleys, and mounted in suitablebearings in the usual manner. B 'represents a head, secured to the `front end ot' the mandrel A.- On opposite edges of this head B, I form recesses, in which arepivoted the arms C, by means of pins e. To the rear ends of' these arms C are pivoted two'arms or links D, having their opposite -onds jointed together, asshownia figs. 1 and 2, and united by means of the joint-pin r to a sleeve, E, which slides loosely to and `fro on the mandrel A, a-pin passing from the sleeve E into a slot in the mandrel on each side, which prevents the sleeve E from turning. independent of the mandrel. A circumferential groovel is formed in the exterior of the sleeve Efasshown'in figs.. 2 and 3, to receive the forkedends of a lever, G, pivoted to the top of a post, F, secured'to the -bed of the machina-as represented in iig. 1, this lever- Gr serving to slide the sleeve E baek'and forth on the mandrel A. In the outer-end of the arms C are secured the cutting or screw-dies s, the.' end of the arms C being enlarged, to form a seat for them, and beinglprovided `with set-screws o and @for adjusting the dies as maybe required. `The other parts of the machine are constructed in the usual manner, and need not therefore be described.
The operation is as follows: The bolt being secured in the support P, and the leverG moved so :1s-to open' the dies c, ns represented in iig. 2, the support P, with the bolt, is moved forward, so as to bring the bolt between the dies c, when the lever G is moved so as to slide the sleeve E forward, which brings the links D into a straight line, or nearly so, as represented in tig. 1. This moves the rear ends ofthe arms C apart, and of course causes their front ends to approach each other, and thereby causes vthe dies c to close upon thebolt which has been thrust between them. Thcn,`by rotating the mandrel A, tl1e dies are caused to rotate also, and, of course, 'ont a thread upon the bolt. The links D, operatingou the plane of the knuckle-joint, exert great power, and, when brought to a straight line, will hold the dies securely in place until the lever G is reversed. By these means I construct a machine that can be operated with ease and rapidity, and that performs its operations in va most satisfactory manner.
Y Having thus described my invention, what Iv claimis The die-holding levers C, pivoted to the head B, secured tothe end of'tho hollow mandrel A,.connected by the links D to the sliding collar E and the lever'G, all arranged to operate as shown and described.
E. M.` MAYO.
