%I?EtZhTI-"ECAIItON forming part of Letters Patent No. 332,578, dated December 15, 1885.
Application filed March 5, 1885. Serial No. 157,822. (No model.)
To all whom it may concern:
Be it known that I, THOMAS H. Woman, of Meredith Village, in the county of Belknap and State of New Hampshire, have invented a new and Improved Taper and Pulley Turning Attachment for Engine-Lathes, of which the following is a full, clear, and exact deseription.
The object of my invention is to provide a new and improved attachment for enginelathes, whereby the tool-holder is automatically shifted to turn a convex face on the rim of a pulley or to turn a bevel, as may be desired.
The invention consists in the arrangement and combination of parts and details, as will be fully described and set forth hereinafter.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of referenceindicate corresponding parts in all the figures.
Figurel isa longitudinal sectional elevation of my improved pulley-turning attachment for engine-lathes. Fig. 2 is a plan view of the same, parts being broken out. Fig. 3 is an end view of the tool-holder. Fig. 4 is a plan view of a modification. Fig. 5 is a side view of the same. Fig. 6 is side view of the attachment for tapering. Fig. 7 is a plan View of the same.
The tool A is bolted on the part B,which is arranged to slide on the plate 0, which is bolted to the tool-post holder D on the lathecarriage E. A lever, F, has one end pivoted by a pivot, G, to the top of the plate 0, a recess, H, being formed in the under side of the pieceB for receiving the end of the arm or lever F. A block, J, is arranged to slide in a groove, K, in the under side of the block B, and a pin, L, is passed through the block J into the lever F. 011 the lever F a slide, K, is mounted,whieh is held in place by a binding-screw,K,and on the said slide K a swivelstud, L, is arranged, in which one end of a bar or red, M, is held, the other end of the rod being held in a swivel-stud, N, on a slide, 0, held in place by'a screw, 0, on a bar or rod, P, projecting from the lathe-bed Q to which it is fixed. The tool A acts on the outer face of the rim of the pulley R. The carriage reeiprocates in the direction of the arrow a and in the reverse of this direction.
The operation is it follows: Supposing the carriage to be moving in the direction of the arrow a, Fig. 2, and the tool has arrived at the middle of the rim of the pulley,as shown in said figure, as the carriage continues its movement in this direction the lever F will by its connection to the fixed bar P on the lathebed and to the tool-holder, cause the latter to be moved in the direction of the arrow a until the tool arrives at the edge of the pulley being turned, when the parts will assume the position shown in dotted lines. The carriage is then moved in the reverse direction of the arrow a, when the tool-holder will be moved in the reverse direction of the arrow a until the tool arrives at the middle of the pulley, when the tool-holder will again begin and continue to move in the direction of the said arrow a until the toolarrives at the other edge of pulley.
By repeating the above operation a convex curve will be formed on the rim of the pulley.
The block J may be removed from the pin L, and an ogee or other shaped groove made instead of the plain groove K, that would give other movements to the tool.
If the arm or lever F is pivoted to the piece 0 by means of the pin L, and the bolt G eonnects the arm F with the piece B, the toolholder, instead of being moved from the pulley as the tool approaches the middle thereof, will be moved toward the same, thereby forming a concave curve in the outer surface of the rim of the pulley in place of the convex curve in the manner described. The curve on the rim of the pulley can easily be changed by adjusting the slides K and 0 different distances from the pivoted or fixed ends of the arm I and lever F.
If desired, the lever or arm F may be pivoted on the back of the tool-carriage E, as shown in Figs. 4 and 5, the connection with the arm P remaining the same. Communication between the arm or lever Fand the toolpost hold D is established by means of the link or lever S, which is pivoted to the tool-post holder D and to the inner end of the lever or arm F. The lever S has a longitudinal slot,
S, in which the block S is held, which is fastened on the lever F, and the slot is provided, to allow the tool to move up to the pulley when the block S is not held fast by a set-screw, 8. Between the handle U on the feed-screw and the carriage E a short space is left to permit the screw to move with the tool-post, in order that the lever or arm F may control the tool. The connecting-lever S may be connected with the nut that holds the feed screw, which obviates the necessity of the space between the handle and the carriage. The connectinglever S, omitting slot S, may be used instead of block J and groove K shown in Figs. 1 and 2. The operation is the same as with the construction shown in Figs. 1, 2, and 3, andthe parts are adjusted for turning convex or concave pulleys by connecting the lever S te the lever F on opposite sides of the pivot ofthe said lever F.
For turning bevels, an angle-lever, a, is substituted for the lever F, which anglelever is dovetailed and works in a dovetailed: groove, b, in the piece 0. A slide, d, is secured at an angle on the lever a, and passes into a groove, 9, in the bottom of a. block, h, pivoted on the under side of the plate B by the bolt 70. Vhen the carriage moves in the direction of the straight shank of the angle-lever a, the said lever slides through the. groove 12, and the slide d slides through the groove in the block h, and as it is held at an inclination to the shank of the lever-aitmoves the piece B and the tool-holder on it in-the direction of the arrow m during the stroke in one direction and in the inverse direction ofthe arrow m during the return-stroke. A bevel can thus be made on the rim of the pulley or other work,which bevelcanbechanged= f by changing the positionof the slide d, which has a slot, n, through which a screw, 0, is passedfor holding the said slide d in the desired position on the short shank of-the lever'a. Only one half of the rim of the pulley'is turned at a time, and then the pulley is reversed so that the other half can be turned.
The above-described machine can also be usedfor any other taper work.
