IMPROVEMENT IN GAGE-LATHES.

Specification forming part of Letters Patent No. 53,003, dated March 6, 1866; reissue No. 7,262, dated August 15, 1876; application tiled December l, 1875.

To all whom 'it may concern:

Be it known that I, LIVERAS HULL, of Charlestown, county of Middlesex and State of Massachusetts, have invented a new and useful Mach-ine for Dressing Whip Handles or Stocks, or other articles of like nature; and I do hereby declare the following to be a correct description thereof', when taken in connection with the accompanying drawings, in Which- Figure l is a plan or top view of the machine; Fig. 2, a front elevation, Fig. 3 a rear elevation, Fig. 4 a longitudinal section, and Fig. 5 a transverse section, of it.

The object of this invention is to properly round and shape the'handles or stocks of Whips and other articles of a like nature. To accomplish such an object correctly it is necessary that the stock shall travel longitudinally toward the cutting-edges, or vice versa, so that the material removed from the stock may be stripped or cut lengthwise of the stock instead of around it or transversely, and so that the surface Will be thereby left smooth. It is also essential that the proper taper or shape should be given to the stock at the same time that its surface is being iinished; consequently it is necessary that the cutting devices be controlled by a guide corresponding to the taper or form of the stock; and, therefore, this invention consists, chiefly, in the combination ofa holding and feeding mechanism, and revolving cutters, having their axis of rotation at right angles, or nearly so, to the axis of the stock, and guides for controlling the action of the cutters, as will hereinafter appear.

As shown in the drawings, the frame is represented at A, and is of any suitable form to support the other parts of the machine. Upon said frame is mounted a carriage, B, which is arranged to travel on guides or rails a c, for the purpose ot' giving longitudinal motion to the stock. Upon said carriage are mounted the standards b c, for supporting the mandrels cI or d, which hold the stock in proper position to be guided to the cutters. Said mandrels are rotated by suitable gearingfg, in such manner as to keep the stock constantly revolving while it is under the action of the cutters.

The means of attaching the stock to the mandrels is by clasping each end between a pair of levers, it, which are pivoted on opposite sides of a head, h, which is mounted on the inner ends of the said mandrels, and thereby serves as a fulcrum to the levers, as also a means of revolving them.

Between the outer ends of each pair of said levers there is arranged a cone, K, which can be longitudinally adjusted by a screw formed on the mandrels, so as to spread or release the outer ends of the levers, and thereby close or open their inner ends, between which the opposite ends of the stock may be held in proper position to the cutters. The revolving-gear of said mandrels is shown at M M, engaging with the gears f g, arranged between the posts n n on the carriage. A shaft, o, iinparts action to the said gears by a feather connection, which' allows of their sliding on the shaft, and said shaft may be rotated either by a crank, g2, or a belt and pulley. The standards b and c are capable of adjustment relatively to each other to Iadapt the machine to various lengthsofstocks. Thecarriageorsupportthat holds and moves the stock longitudinally is set in motion by a belt, S, on the wheels t t, which are xed on the shafts u o, or it may be moved to and fro on one of said shafts by a crank,

of, upon the shaft u. The cutters or burrs are represen ted at C C, and, as shown, are mounted upon shafts W W, placed at right angles to the axis ofthe stock, or a line extending between the centers of the opposite clampinglevers z' t'. Said cutters or burrs are cylindrical heads, whose surfaces may be roughened as a iile or resp for cutting away the surface ofthe stock, as it passes between them or in close proximity to them, or one of them, for it is evident a single cutter may be used, working only on one side vat a time, provided the vstock be held in a sufficiently iirln position.

Said cutters, mounted on their shafts W WV, are supported by adjustable frames D D, which are carried by two auxiliary frames, E E, that rest on cross-bars :v m x x, as shown at Fig. 4. Each of the shafts W W is provided with a driving-pulley, a2, and they are driven by a band, b2, receiving motion from the pulleys c2 c2, whichare on a shaft, d2. Each of said auxiliary frames is provided with suitable mechanism for opening and closing the space between the cutters to vary the d-imensions and form of the whip-stock, and the devices are niider the control of a patternguide, which is shown at k1, and which is conuected with the cutters as follows: (but it is evident that the intermediate devices may be greatly varied without departing from .the nature of myinvention, as it is evident that the guide may be niade to move instead of being fixed, as shown in the drawings.) Each of the auxiliary frames E E is provided with a setscrew, y, and adjusting-nuts Z Z, for adjusting the cutters relatively withthe axis of the whip-stock.

Connected with said frames E E are connecting-links al al, which are pivoted at one end to the frames D E, and at the other to a lever, b1, havingaT-shapcd end, and supported on an axis which is supported in bearings d1 d1, as shown in Figs. l, 2, and 5, and each of said connectinglinhs is made capable of adjustment by the nuts g1. A 'bent lever, hl, having -an axis, G1, as its fulcru'm, is provided -with a pin, t", by which it may be engaged with the T-ended lever b1, and by which it may operate said lever b1. The other end ot' the leverh1 is provided with two pins, that clasp the pattern-guide k1, which extends up like a ange between the pins, and is adjusted and held iii a iirm position by the set-screws in] m1, which extend from the patternfsupport l', and which, in this case. is attached to the carriage or feeding mechanism, and travels with the stock, so that it is moved past the cutters, and its form determined by the form ot' the said pattern. The cutters are also arranged so as to be constantly changing their cuttingedges upon the stock, andthereby prevent their becoming worn into grooves, and from becoming clogged by such substances as whaleboue, &c., of which the tips of stocks are often made. rlhis change is e'ected by resting the shafts of the cutters upon levers which are operated by cani-wheels rlr on the shaft S1, which is provided with a pinion, tl, which gears into the pinion o', firmly xed on the lower end ofthe vertical shaft o.

A worin-gear, w', on the shaft o, engages with the worm x on the shaft O, and thereby motion is imparted to the cams to operate'the levers, that gradually raise and lower the cutter-heads to change their position ou the stock.

The whip-stock is supported near the cutters by passing it through notches or openings as in two plates, y z', as shown in Figs. 1, 6, and 7, which are arranged to slide one upon the other, so as to bring the openings ai* into such relationship as' to close upon the stock and steady it under the cutting action. Said plates workin the standards b3 c3, and are drawn endwise by a spring, d, attached to the plates and the standards.

The plates are also under the control of a lever, e3, which is held by a catch,f3, to hold the plates in such a position that the stock may be easily inserted or taken out, as desired.

The carriage maybe moved automatically by gearing connected with it, similar to a planer, instead `of by a crank, as already inentioned.

This mechanism is shown as consisting of a shaft, g3, supported in bearings h3 h3, Fig. 3. Connected therewith is the bevel-gear i3, on the lower end of the shaft, engaging with the pinion t1. On the other end of shaft g3 is another bevel-gear, 7a3, which engages with a wheel, t3, carried by the tubular shaft, m3, (see Fig. 8, which is a vertical section of said shaft) and the shaft u and clutch a3; and said clutch is-operated by a lever, o3, which serves to connect the two shafts u andm, and when so connected will cause the carriage to move forward. A haudle,p3, provided with a springlatch, q, is attached to the clutch-lever 03, to operate it to force the two parts of the clutch together, and a spring, r3, attached to the frame A, and to the handle p3, tends to force i them apart whenever the spring-latch is released; aiid this is accomplished by a projection, r4, upon the side of the carriage, striking the latch g3 as the stock is completed, and it thereby stops the operation.

It is evident that the stock, in being rounded, will be carried endwise toward the cutters, and also Arotated at the same time, and that the operation will he performed automatically.

I therefore claiml. In a machine for shaping whip-stocks, the combination of two rotating and adjustable clamps for holding the whip-stock with revolving cutters, whose axis of rotation isat right angles to the axis of the stock, substantially as described, for the object set forth.

2. In a machine for shaping whip-stock, the combination of revolving cutters, the adjustable and rotating clamps for holding and revolving the whip stocks, and the guides though which the stock is passed for firmly holding the stock while being dressed by the cutters, as described.

3. In a machine for dressing whip-stocks, the combination with revolving cutters, whose axis of rotation is at right angles to the axis ot the stock, of mechanism, such substantially as described, for moving the cutter or cutters in the direction ot' the aXis of the same, as and for the object specified.

4. The adjustable rods or connecting'liiilis a1 a1 with the cutter-frames or carriages D E, with levers bl and h1, arranged to operate with the pattern-guide k1, substantially as specilied.

5. The combination of the straining or tensioii mechanism, with the rotating mandrels c1 d, and their jaws for holding' the whipstock strained or taut, substantially as described.
