IMPROVEMENT IN CIGAR-TRIMMERS.

Specification forming part of Letters Patent No. 129,101, dated July 16, 1872.

To all whom it may concern:

Be it known that I, JOHN H. CHRISTMAN, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Cigar-Gutters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which Figure 1 is a side view of my invention. Fig. 2 is a cross-section taken on the line 3/ y, Fig. 1. Fig. 3 is a cross-section taken on the line as 00, Fig. 1; and- Figs. 4 and 5 are detail views.

Similar letters of reference indicate like parts in the several figures.

This invention relates to certain improvement in knives for cutting ofi' the ends of cigars in their manufacture, whereby the work is done in a neat and rapid manner, and a desirable cutter obtained, as hereinafter described.

In the accompanying drawing, A and B are the blades of the cutter or knife. They are pivoted together at D, and the lower blade is fastened rigidly to a suitable table by screws at c c, Fig. 1, and the upper blade is actuated by a blow with the hand on the knob E. Each blade has its cutting-edge in form of a semicircle, as shown at A and B, Fig. 1. These semicircular cutting-edges compress the cigar fairly, so that it is not broken before the cutting begins. The blades are thrown open by a coiled-wire spring, F, that is securedin place by bending its ends at right angles and inserting them into holes f f in the opposite blades. The upper end of the spring is upset in the hole so as to not be removed; but the lower end is placed in its blade so as to be withdrawn at any time, and placed in the screw-hole 0 so as to hold the blades together and facilitate packing. The blades are cut out of thin sheet-steel by dies, and the knob E is fastened to the upper one by slitting its stem so as to straddle'the back of the blade, and is-secure'd thereto by a pin, 6, that can be taken out at any time to remove the knob when the blade requires grinding. The pivot D is made as follows: The pivot-hole in blade A is round, but that in B is half round, as seen in Fig. 4. The pivot D is also made half round, as shown in Fig. 5, and it turns loosely in blade A, but

is fixed in the blade B so that when thenut d is screwed on there is no motion between the blade B and the pivot, and the nut 01 has no liability to move by the working of the machine from any position in which it is set, thus making it entirely reliable, while the parts can be readily taken "apart for sharpening or be set together to compensate for wear. The blade B has a slot, G, which is occupied by a set-screw, g, that screws into the opposite blade and acts as a guide for the blades with relation to each other. This screw passes through the slot of B and screws into the plate of A, but has a check-nut, h, Fig. 3, on the opposite side of A, to bind the screw in said plate or blade. On the blades A and B are secondary blades H H for splitting the tuck or remnant at the same time it is cut from the cigar, so that it can be used as filling thereafter. These blades H H have a shearing cut, and are fastened to the main blades by screws, as seen in Fig. 1.

In putting the blades A B together they are bent slightly, so that their outer ends tend to overlap to make a close out, and to prevent them from interfering while they are so shaped the outer end of each blade or plate is beveled, as shown in cross-section, Fig. 2, a b being the portions that are beveled. In addition to the guide 9 G, I fasten a guard, J, on the outer end of the blade A, Figs. 1 and 2, which engages with the upper blade B before the cut begins to hold the said blades firmly together to insure a clean shearing cut.

The form of the cutting-edges A B, Fig. 1,

is that of a perfectcircle, slightly larger than I the cigars, which gives the best result.

By these means I obtain a cutter of a durable and easily-regulated construction, andthat does its work in a superior manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is'

A cigar-trimmer composed of the pivoted overlapping blades A B, splitting-knives H H,

concentric guide slot and bolt G g, and spring F, constructed and arranged as described, and for the purpose set forth.

The above specification of my invention signed by me this 19th day of August, 1871. Witnesses: JOHN H. CHBISTMAN.
