Letters Patent No. '110,0i6,dated December13,1870.A

IMPROVEMENT IN 'eonK-MAcHnnae.

The Schedule referred to in these Letters Iatent and makmg part of the same.

To all whom it may conce-rn Be it known that I, EILERT O. ScHAn'rAU, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cork-Cutting Machinesgtand I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to the .accompanying drawings and to the letters of refer- .ence markedthereonwvhich form a part of lthis specification. They nature of my invention consists in the construction and arrangement of a machine for ciitting corks from strips already out of the desired thickness. Y

AIn order to enable others skilled in the art to which my'invention appertains to make and use the same, I will now proceed to describe its construction` and operation, referring to the annexed drawings, in`

cated with a view of cutting many-corks at once.

` The object of my improvement has thereforcbeen of constructing a cork-machine that combines the :precision and quickness of work derived from the use of machinery with the saving of materials, the avoiding of defects in the cork-wood, and also the facility oi' improving 'on thequality of the work `by an immediate inclining of the circular knife.

For cuttingcylindrical coi-ks I have invented a steeled iron or brass tube.

y This construction of the knife presents some marked advantages over the cylindrical knives now in use for cuttingA corks.

The cost of my steeled knives is reduced to onethird; the steel attached tothe brass tube admits, in

.consideration of its shortness, of a perfect working` and tempering; the steel may be used for cutting to the very last, while itis evident that the'brass stock cannot undergo any colisiderable wear, even by a con stant use of it for many years. 'v

A represents the lathe-head, supporting a hollow mandrel, B. y I To this latter is thezstocked cylindrical knife O attached, the adjusting-screws@ a serving both to hold and center up the knife.

E represents the -poppet-head, supporting a centershaft, F, headed by a slide-rest, G, the whole moved backward and forward by the lever H.

A set-screw, I, regulates the motion of said lever.

The end of the strip of cork-Wood is lightly pressed against a knob, b, upon the face of the slide-rest G,

and by-a forward motion of the lever H the cork is .cut and passes through the mandrel B, one cork push'- ing the other.

The knife C is, as above described, composed of an iron or brass tube with steel end, and may be ex-V changed for another o f different size when it is desired to cut corks of larger or smaller diameter.

The slide-rest G has to be adjusted, up or down, to correspond with the knife used, so as to bring the knob b to the proper place. Y v

The device supporting the poppet-head E -is also adjustable, so as to bring it closer to or furtherv from the knife, for different thicknesses of corks, and fastened by a set-screw at the desired point.

The corks having been cut cylindrical, if it is dc.- sired to make them conical, the tapering is'done by a plain circular knife, N, which is lattached to a pulley, l), said pulley and knife being mounted upon a slide-rest, Q, placed or attached to a knucklejoint, It. l

The combined motions of the slide-rest Q and knuckle-joint R permit the operator, while running the machine, to incline at will the knife N, either to the right or left, or toward the center, as the defects of the cork-w ood may require.

The cylindrical cork is pressed between two centers S S, one attached to the mandrel T, carrying thc cork, and the other simply turning round on its ccnter in the connecting-mandrel U, which,fhy the ac-v tion of the `lever V, spiral spring Y, and-a trcadle, has

a backward and forward motion, required for the holding of the cork, and its letting loose-after having been cnt.

Then .it is required tha-t the knuckle-joint ItA shall havesa permanent position,.the set-screw W' secures it firmly in place, and in order to limit and regulate the motion of said joint it is trausversed by au axle, D. l

The circular knife N may be raised and lowered at will, and adjusted by means of the screw/I.

Having thus fully described my invention,

NVhat I claim as new, and desire to secure4 by Letters Patent, is-

1. The circular knife N, provided with pulley I?,

and journaled upon slide Q, substantially in the Inany Witnesses:
