LI MI Cutting Slate. No. 88,037. Patented March '23, 1869.

IMPROVED SLATE-PUNCHING Ann CUTTING MACHINE.
The Schedule referred to in these Letters Patent and making part of the same.
I ings, and to the letters of reference marked thereon.
The nature of my invention consists in combining, with a revolving table, upon which the slate to be punchedand cut is laid, a punch-carrying lever, the operation of whichis to punch the slate, and hold it rigidly in position while being cut.
My invention further consists in combining, with said revolving table, a cutter-wheel, which serves to out the slate as desired; and also in combining, with said table, a series of semicircular bars, of different sizes, so arranged that any one or more may be detached fromthe. table, and thus allow the cutter-wheel to be so adjusted that the endof the. slate may be out into a curve of any desired radius.
To enable others skilled in the art to make and use my invention, I will proceed todescribe its construction and use.
In the drawings- Figure 1 represents a perspective view of my invention.
Figure 2, a plan of the table, with one of the adj usting semicircles removed.
Figure 3 represents one of the adjusting semicircles.
I construct my machine as follows:
A is the base, which is attached to standards B and D.
To the standard B, the table K is attached by any suitable swivel-arrangement which will admit of free revolution, and will at the same .time securely hold the table in position.
L is a lever, pivoted at n n, figs. 1 and 2, and having secured in slots S S, two punches M M, the heads of which only are shown. These punches may be adjusted in slots by means of set-nuts.
The rounded end of the table K has a semicircular recess, into which a number of semicircular pieces 0 O is set.
F is a mandrel, secured to the head-block E by the set screw G, and carrying upon its end the cutter-wheel H.
To use my machine, I proceed as follows:
The table K being turned so far around that the cutter-wheel H will be at one side, and the lever L-being raised, the slate to 'be operated upon may be laid upon the table K. Now, by bringing down the handle L rapidly, the points M M pass through the slate, punching two holes, and holding the slate securely in position.
If, now, the table be revolved, so as to bring the slate in contact with the cutter-wheel H, it will be cut with a rounded end.
To release the slate, after being punched and out, I have simply to raise the lever L.
The adjustments of my machine are as follows:
The pivots upon which L plays may be moved from n to 'n n", 8tc., as it may be necessary, in case we wish to punch holes nearer to or more remote from theend of the slate.-
To round ofi" the ends of narrow slates, or to change the radius of theedge of the slate, we have simply to -remove one of the semicircular bars, 0', for instance,
and to move up the wheel H, so as to touch the edge of 0.
What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In a slate-cutting machine, the revolving table K, in combination with the cutter-wheel H, arranged and working s.-.bstantially as described and for the purpose set forth.
2. The punch-carrying lever L, arranged and working in combination with the table K, substantially as described and for the purpose set forth.
3., Combining, with the table K, the semicircular adjusting-pieces O O, 860., substantially as described and for the pu pose set forth.
L. M. HAM.
