Lette/rs .Patent No. 85,629, (lated January 5, 1869.
IMPROVEMENT' IN HUB-TURNING- MACHINE.
The Schedule referred to in these Letters Patent and making part of the same. l
To all whom it Imay concern:
Be it known that we, J. J. ZUFELT and R. CRAIG, of Sheboygan Falls, in the county of`Sheb`oygan, and tate ofisconsin, have invented a new and useful Improvement in Hub-Turning Machines; and we do hereby declarethe following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective -view of our machine.
Figure 2 is a plan of the same.
Figure 3 is a front elevation.
Our invention consists in a combined roughin g, turning, and cupping-machine,by the continuous operation of which a suitable block of wood is converted into a finished hub, without rehandling, and while upon the and unimportant. A
For the purposes of this' application, it will not be necessary to enter into an extended description of the construction of the machine, further than concerns those parts which We have invented.
The mandrel A and ytail-stock B are mounted, in the usual way, upon suitable heads or blocks, and the hub C, after being bored, is placed upon a suitable mandrel, and is hung upon the centre in the lathe.
Heretofore it has been customary to rough-shape the blocks with an axe, though machines have sometimes becn employednto perform this operation, separate and distinct from the operation of shaping and smoothing; and when the axe is employed for this purpose, it has rendered it necessary to impose so -much labor upon the shaping and smoothing-knives, that they have become dullcd and inefficient very quickly.
At the back of the main frame we erect a strong wrought-iron frame, l), and from the upper portion of this frame we extend the brace-bar guides E forward, and connect them to the head and tail-blocks, so as to render not only the frame D rigid, but the guide-bars also very rln.
These guide-bars are dressed smooth and true, and upon each is mounted a sliding head, F, which travels upon-said guides, to bring the roughing-cutters to or from the work. l
The sliding heads F are cach provided with a setscrew, G, by means of which they may be clamped to the guide-bars at any point, as they only require shifting to adapt the machine to .the turning of large or 1 small hubs.
The cylindrical shaft H connects the sliding heads,
, and is rigidly secured to each.
This shaft is the guide upon which the roughingthe hub-block.
The cutters I I l (heilig in number greater or less than three, as desired) are secured directly to the traveller J, by screw-bolts which permit the cutters to be adjusted forward or backward, to regulate their depth of cut, or to compensate for wear.
The traveller J is mounted upon the shaft H, and secured in proper position theroonzby a strap, which passes over said shaft, and is secured to the traveller on either side thereof.
The front end of the traveller lies upon the rest K, the ends of which are connected with the ends of the sha-it H by means of the arms L L, and they are also so notched as to fit over the edges ofthe guide-bars E E, and be thereby prevented from sliding or moving endwise during the operation of the machine.
lhe handles M N, also secured to the traveller J, enable the attendant to control the operation of the roughers from either the front or end of the machine.
A strap, (),'is secured to the lower side of the traveller J, and passes beneath the rest K, so as to hold said traveller and rest in contact, and yet permit the traveller to move freely upon said l'est, from end to end thereof. l l
lhe operation of this part of our invention will be easily understood. v
The traveller J, being drawn to one end ofthe shaft H, the rough block is placed in the lathe, and the machine started.
Each succeeding cutter I cuts deeper than its predecessor, and, inpassing once across the block, it is reduced from its roughffbrm to a true but rough-surfaced cylinder, and is ready for the shaping and smoothing-knives, which, carried upon suitable carriages, are brought up to the work by arrangements of mechanism which are well known.
Then the roughing-cutters have performed their office, they are placed out of the Way by turning the traveller J and rest K bodily back upon the shaft H, until the upper sides ofthe cutters rest upon the edge of the frame D.
This reversal of position, as well as the direct movement during operation, is shown in red lines in iig. 2. In this position they remain until required for use upon a fresh block.
The roughing, shaping, and smoothing having been finished, the next operation is to form the cup in the outer end of the hub.
My apfmratus to perform this operation is attached to the tail-stock of the lathe, and is operated by a handlevcr, l, attachcdat one end by a link to the foot of thc brace-bar E, as shown in iig. 2.
The yoke Q, to which this lover I is attached, is pifoted at the ends oi' its branches to a sliding head, it, which slides upon the tail-stock ofthe lathe.
At the front end of the yoke, it is formed te lit over I "is v the convex cylindrical surface of the mandrel which holds the hub, and to this part of said yoke is secured, by a set-screw, a cutter, S, of proper form to shape the interior face of the cup.
During the preceding operations of roughing and shaping, the clipping-tool and its yoke are raised upand turned back upon the tail-stock, as shown by red lines in fig. 3, so that it is entirely out of the way.
When the shaping and smoothing-tools have finished their task, they are pushed back out of the way, and the yoke Q is brought over to its working-position, its front end rest-ing upon and sliding on the mandrel which holds the hub. i
By means ofthe lever P, the cupping-cutter S is then pressed against the end of the block, and the cup is quickly formed.
When completed, the cupping-tool is run back, and the yoke raised to the position indicated by red lines in iig. 3.
The cutter 3 isorged in the form shown in the draw- I ings, i. e., with its edge turned up, and with solid corners, so that a continuous cutting-edge is secured from end to end.
The setscrew G passes through a slot in the cutter, and into the yoke, so that the cutter may be adjusted forward or backward, as desired or fonndvto be necessary.
Having described our invention,
That we claim as new, and desire to secure by Letters Patent, is-
l 1. In combination with the shaping and smoothingcutters of a hub-turning machine, the rougliing-cutters I I I and traveller J, mounted upon a guide-frame, D E, or its equivalent, which will permit the free movement of said cutters in a line parallel with the axis of the hub to be turned, and with an adjustment to or from said axis, substantially as set forth.
2. The combination and use, in a single machine, of the roughing-cutters I I, shaping and finishing-tools U U, 4and the clipping-tool S, substantially as set forth, so-that, by a continuous operation, without changing the velocity of the revolution of the hub being shaped, the same may be roughed, shaped, smoothed, and cupped, substantially as set forth.
