BALL-,TURIN l N G LATH E.
SPECIFICATION forming part of Leners' Patent 10.353,994, dated May 31, 1887.
Application tiled September 3, 1886. Serial No. 212,636. (No model.) I
To all whom it may concern.:
Be it known that I, TRoNsoN DnAPnR, of Petrolia, in the Province of Ontario and the Dominion of Canada, have invented a new and-Improved Ball-Turning Lathe, of which the following is a full, clear, and exact description.
The object of my invention is to provide a new and improved lathe for turning or rounding balls.
The invention consists of an adjustable faceplate covered with leather and back ed by ,rubber or other elastic material, of a pair of tongs having steel cups, of an adjustable steel cup placed on a holder, of a hall rest, and means for. adjusting the steel cup holder.
The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a longitudinal sectional elevation of my improvement, showing a pair of tongs applied. Fig. 2 is a side elevation ofthe same, showing the device for finishing the ball. Fig. 3 is a face view ofthe same, p'arts of the face-plate being `broken out. Fig. 4 is a ver; tical central section of the steel cup and its holder. Fig. 5-is a face view of the steel cup; and Fig. 6 is a face View of a moditied form of the steel cup.
On the base-plate A aresecured the standards B, in which is mounted to slide and to rotate the spindle C, into the rear end of which projects centrally the screw D, having the annular recess` D', into which passes the setscrew E, screwing in the spindle C, and thus attaching the screw D to the spindle C and permitting a rotary motion of bothlindependently of each other. The screw D screws 'in an arm or bracket, F, secured to the bracket B, and is provided on its outer end with a hand-wheel, G.
Betweenv the two standards B is placed a driving-pulley, H, secured to the spindle C, and on the inner end of the latter is secured the face-plate I, consisting of the disk I', covered on its face with a disk, I2, of rubber or outer end a steelcup,.K2, having the inner cutting-edge, K3.
The steel cup L is fastened on the end of the holder L', which is provided on its upper end with the screw-threaded portion L2, on which screws the cap or guide M held at any desired point on the part L"' by the jam-nut N, also screwing on the part L2. The holder L is provided with thehandle L3, and the'lower end of the holder rests, when applied, in a socket formed in the'center of the hand-wheel O, attached to the screw I?, screwing in the keeper Q, secured to the base-plate A.
The cutting-edgesof the cups K2 and L may be of various shapes,r as shown Ain Figs. 5 and 6.
The operation is as follows: The ball R, which is cast with a stem, R, is screwed into or otherwise fastened to the lathespindle C, in front of theface-plate I, and is revolved with the said spindle C. The operator then takes hold of the tongs K and presses the steel cups K2 over the ball R, as shown in Fig. l, and then moves the tongs K from side to side, at the saine time pressing the prongs K together, so that the cutting-edges K3 of the cups K2 come in contact with the surface of the ball R' and thus round the same. The stem R- ot' tool or the usual lathe-tool, soas to complete as ynearly as possible the spherical surface of and 8, so that thelower end of the holder L rests in the hand-'wheel O and the cup L partly encirclesthe'ball R, and the latter is pressed against kthe cushioned leather disk I3, so that the ball rotates, by the frictional conthe ball R is then carefully cut off by a handi k I the ball. The latter is then placed on the rest .threaded bracket F, in which screws the screw tact with the revolving face-plate I, in the cup L. The cutting-edge of the latterremoves all the inequalities of the ball.
The guide or cap M prevents the ball from falling out of the cup L, and is adjustable on the part L2 to suit the respective diameter of the ball, and is-held in place by the jam-nut N. The cap M also rests on the inclined edge J of the rest J. The ball R is pressed more or less against the leather disk J3 by turning the hand-wheel O, so as to cause the holder L to slide toward or from the face-plate I. The ball is thus completely rounded and Iinished.V
Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a'balleturning lathe, the combination of a cushioned leather-covered 'faceplate with au adjustable spindle, substantially as shown and described.
2. In a ball-turning lathe, the combination of a cushioned leathercovered face plate with the spindle G, turning and sliding in the standards B, the screw D, having the annular groove D', the set-screw E, and the screw- D, substantially' as shown and described.
3. In a ball-turning lathe, the combination of the cushioned 'leather-covered faceplate I and the spindle C, carrying the said face-plate and the ball to be turned, with a pair of tongs, K, having steel cups K2, substantially as shown and described.
4. In a ball-turning lathe, the combination of theadjustable cushioned leather-covered face-plate I and the spindle C, carrying the i said face-plate, with the ball-rest J, substan# tally as shown and described.
5. In a ball-turning lathe, the combination, with the faceplate I, having the rubber backing I'l and the leather disk I, of the cup L, supporting the ball to be turned, substantially as shown and described.
6. In a ball-turning lathe, the combination, with the face-plate I, provided with the disks I2 and I3, of the cup L, supporting the ball to be turned, the holder L', and the adjustable cap or guide M, screwing on the said holder L and held in place by a jam-nut, substantially as shown and described.
7. In a ball-turning lathe, the combination, with the faceplate l, covered with the disks l2 and Ii", ofthe rest J, having the inclined edge J', the cup L, supporting the ball to be turned, theholder L', having ascrew-threaded portion, L2, and the cap or guide M, screwing on the part L2 and held in place by the jam-nut N, substantially'as shown and described.
8. In a ball-turning lathe, the combination,
-with the face-plate I, covered with the disks l2 and I, of the rest J, having the inclined edge J', the cup L, supporting the ball to be turned, theholder L', having ascrewthreaded portion, L2, the cap or guide M, screwing on the said part L2 and held in place by the' jam-nut N, the handwheel O, supporting the lower end of the holder L', the screw P, attached to the said hand-wheel O, and the screw-threaded keeper Q, in which screws the screw P, substantially as shown and described.
