SALMON W. PUTNAM, OF FITCHBURG, MASSACHUSETTS.
IMPROVEMENT iN METAL-WORKiNG LATHES.
Specification forming part of Letters Patent No. 192,129, dated .lune 19, 1877; application filed September 12, 1876.
To all Awhom it may concer/u:
Be it known that I, SALMON W. PUTNAM, of Fitchburg, Massachusetts, have invented certain 'new and useful .Improvements in Metal-Working Lathes, of which the following is a full,clear, and exact description, reference being had to the accompanying drawings, making a part ofthis specification, in which- Figure-1 is a perspective view of a lathe with my improvements attached. Fig. 2 is a longitudinal vertical view ofthe same through the line a: of Fig. 1. Fig. i is a plan view. Fig. 4 is a horizontal section through yy of Fig. 1. Fig. 5 is a cross-section through z z of Fig. 1. Fig. 6 is a front end' view ofV the front box. i
lMy invention relates more particularly to t lathes for metal-working, although susceptible of heilig applied more or less to all tnrir ingl or boring lathes; and it consists, first, in a device to prevent the pendulum-like swing ofthe tie-holts and tie-piece when the bolts are loosened to move the tail-stock backward andv forward on the lathe-bed; secondly, in a novel mode of securing the tailstock to the bed-- piece; thirdly, in a novel arrangement of the` settingovcr bolts to secure the spindle in any relative position to the central line, for the purpose of turning tapers; and, fourthly, in the construction and arrangement of the' spindle bearings and boxes, as hereinafter described and claimed.
To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried ont the several parts referred to.
In the drawings, A represents the lathe-bed, and a a the base-pieces or legs, all of which )rovided with the extension or foot rom which rises the socket b for the receptionof This socket is braced to the leg` c' by the connecting-web b". The legs are provided with the openings l) l), and the lathe-bed with the openings d d,`all extending f, re preferably cast in one piece. y The legr a is /v /7 1 entirely through the machine, for the reception, of tools.
In"the tail-stocks of lathes of this description the vert-ical tightening-bolts have had nothing to prevent lateral swing or play when the bolts are loosened to move forward or backward the tail-stock on the lathe-bed. The result isY that, on the gripe of the bolts being released and the tail-stock moved or suddenly stopped, the bolts and tie-piece are caused to swing,` like 'a pendulum and catchV on the under side of the lathe-bed, to the great annoyance and inconvenience of the workman. To overcome this difficulty I place on the lower inside ofthe tail-stock E the guard holes or slots e e, as shown in Fig. 5. These guard-holes eitectually prevent the swinging of the tic-bolts e e', and yet allow the deadspindle77 to be set over the central line when desired.
To secure the tail-stock E to the bedpiece A, I combine the use of the tie-piece F, the tightening-bolts c e', the eccentric or crank shaft f, the gear G, and the worm-screw g. The upper part of the tail-stock is provided with thearms 4, which furnish bearings for the eccentric shaft f, on which is rigidly sel cured the gear Gr, which is operated by the worm-screw g. Un either end of the eccentric shaft is suspended the tie-bolts e c' by means of an eye on the end of each bolt, which lits loosely over the ends of the eccentric shaft. To the lower ends of these bolts is secured the tie-piece F by means of nuts, as shown in Fig. 5.
It is evident from this description that, as the worm-screw g is turned, the gear Ur will be revolved, and with it the eccentric shaft f, by which means the tie-bolts e c' will be raised and the tie-piece F be drawn tightly against the lathe-bed, thus securing the tail-stock in position, the eccentric shaft being eectually held at any point by the gea'r'and the worin1 screw, and thus avoiding any possibility of the tail stock working loose during the operaion of turning or boring. To release the tailstock from the bed-piece it is only necessary to reverse the. direction ot' the worm-screw.
I am aware that tightenilig-boltsland eccentrics have been used for the purpose of securing the tailstock to the lathe-bed; but, as heretofore constructed, they do not fully meet all the requirements, for thc reason that it is essential to adjust the bolts so that the eccentric centers should be nearly on a line with the belts when the gripe is complete; otherwise the eccentric has a tendency to Work
