GEAR-dlJfT-ER' SPECIFICATION forming part of Letters Patent No. 276,346, dated April 24, 1883.
Application filed December 2, 1882. (No model.)
To all whom 'it may concern:
Be it known that we, JoHN BRooKs and WILLIAM ScULLY, of Detroit, in the county of Wayneand State of Michigan, have invented a new and Improved Gear-Gutter, of which the following is a full, clear, and exact description.
Our improvements relate to machines for cutting beveled and straight spur-gearin g and worm-gearing.
The object of our invention is to provide a gear-cutter that can be used upon any lathe, or upon any machine provided with a pair of centers and a driving-pulley. i
To these ends the invention consists in certain novel features of construction and arrangement, as hereinafter described and claimed.
Reference is to be had to the accompanying drawings,forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of our improved gear-cutten, Fig. 2 is a vertical section, and Fig. 3 is a plan view of the same. Fig. 4 is a vertical transverse section at right angles to Fig. 2.
A is the base-plate.
Bis the standard, fitted to slide upon the base-plate A.
D is the index-wheel, and O is a tubular'socket-piece fitted within the standard B, and formed at its upper end with arms or flanges a a, that are provided with pins E, entering the index-wheel D. y
F is a ring-shaped locking-nut screwed upon the upper end of the standard B, and projecting over the inner edge of the index-wheel D, so as to lock the index'wheel and prevent it from rising. y
G is a screw passing through the bottom of the socket O and entering a recess in the inner side of the standard B, when the screw is fitted with a beveled pinion, K, engaging a similar pinion on a horizontal spindle, I, that is provided at its outer end with a hand-wheel, H, for operation of the spindle and the screw to raise and lower the socket G.
In the upper end of the socket G is to be placed amandrel, b, as shown in Fig. 4, clamped by aset-screw, c, and this mandrel carries the work, which is held in place upon the mandrel by a set-nut, d.
The base-plate A is provided with a screw shaft, e, having a hand-wheel at its outer end for adjustment of the standard 13 lengthwise ot' the base-plate. The standard B is beveled atfto support the index-wheel D,,the object of this being to allow of the index-wheel being locked securely without jamming; and it also allows of ready adjustment for wear.
The socket O and the index-wheel are firmly connected together by the pins E, which act as drivers for theindex-wheel,causing its perfect rotation with the gear being cut, and at the same time allowing of the socket being fed up and down while cutting each tooth.
At one side of the index wheel, and fixed to the standard B, is a slotted post, h, carrying the pin 13, that enters the holes in the wheel.
is k are sector-plates connected by a slotted segmental plate, I, by means of screws that enter a groove, m, in the top of the index-wheel, so that the sector-plates are held firmlyin position, and may be adjusted the properdistance apart for dividing any of the circles of holes into any required number, their action being the same as the sector-arms used on ordinary index-plates.
In using the machine or tool the base A will be supported by the ways of the lathe, and the baseis provided with an apertured lug, 1), for receiving the devices by which itis held in place. The cutter represented at q is upon an arbor, 1, which is fitted to the lathe-center;
For cutting beveled gearing the base A may be attached to the lathe upon the ways by means of a bolt passing through the lug 1), so as to allow of the base-plate being tipped at the angle required; and in cuttingeither beveled or worm gearing the blank may be fed either against or under the cutter with a crossscrew, or at an angle with a vertical screw, whichever may be most convenient. This construction renders the machine complete, so that it may be used upon any ordinary lathe; but if the lathe is provided with a saddle of ordinary character' the base-plate A may be dis pensed with and the attachment applied directly to the saddle.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In gear-cutters, the combination of the too . socket O, the pins E, and index-wheel D to gether and with the supporting-standard 13', substantially as described, for operation as set forth.
2. In gear-cutters, the locking-ringF, com- 5 bined with the index-wheel D and standard B, substantially as and for the purposes set forth. 3. In gear-cutters, the combination of the socket O, fitted for carrying the work, the adjusting-screw G, and beveled gearing K, subro stantially as described.
4. The combination of the standard B, ad-
justing-screw G, socket 0, pins E,'and indexwheel D, substantially as shown and described.
5. The combination of the standard B,f0rmed with a conical or beveled surface,f, and the 15 index-wheel D, beveled at its under side, as and forthe purposes specified.
