Letters Patent No. 109,615, dated November 29,1870; antedated November 26, 1870.,

IMPROVEMENT IN eHo'roeR Pmc PRlNT-CUTTERS.

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

I, JOHN HAWORTH, of the city of Philadelphia and State of Pennsylvania, have invented certain Im-.

provements in Photograph Print-Cutters, of which the following is a specification.

The nature of my invention consists in the combination of a guide-strip of oval or other form, and revolving table, which holds the print to be cut, the eutterguide being connected with a clamping-plate, and the cutter being on a revolvingshaft,-held.by a carrier con-- nected with a swivel-plate, attached to a. horizontal sliding bar. The said bar is helddown hyta spring, whereby the cutter is brought to bear upon the print with suiiicient force to cut through it as the table, above mentioned revolves, as" hereinafter described.

To enable others skilled in the art to which my ilnprovelnent appertains to makeand use myinvention,

I will now give a detailed description thereof.

In the accompanying drawing, which makes a; part of this spe'citication Figure 1 is a. plan of the improved cutter. Figure 2 is a vertical longitudinal section of the same, at the line X X of fig. 1. Figure 3 is an isometrical view of the slotted "outter-carrier H.

Figure 4 is a like view of the swivel-plate J. Figure 5 is a like view of the cap-piece N. Figures 6 and 7 are top and edge views of the guide-strip Ejin a. modified form.

Figures 8 and 9 are modified forms ot' the swivel J. Like letters in all the figures indicate the same parts.

A is the stand, to. which the several parts of the cutter are connected.

B is a revolving table, which turns on the center'- means of its connection with the swivel-plate J hav-' ing downwardprojecting jaws, l) l), slotted at their lower ends, as seen in figs. 2 and 4, so as to have an easy tit over the guide-strip E, to admit of the free turning of the table 13, for cutting the prints The carrier II is shown in detail in fig. 3.

K is a center-bolt, which connects the carrier H and swivel-plate J with the horizontal sliding bar L, the bar having a projecting-plate, M, attached to its front end, against the lower side of which the said swivel-plate is held by the bolt K, passing through the same, and a cap-piece, N, and the nut O, on the upper end of the bolt, being screwed, down upon the said cap-piece, as seen in fig. 2. The eapepicce N is shown in detail in fig. 5.

The sliding bar L rests at its rear end on the bottom of the groove (1 of the permanent bar I, in which it slides, .the front end ofthe bar being pressed downward by means of the spring Q acting through the connecting rods It S, so as to press the revolving cuttcr Fdown'upon the print or paper with sufficient force to cut the same asthe table is revolved by the operator.

' As thetable is revolved the cutter 1 has its dis I tance from the center of the tablevaried, according to the form and the connection of the carrier H, with said strip and with the sliding barL'as before described, whereby the print or paper is out of the exact form of the said 5 1 The size of the printis varied by the adjustment of the carrier H,'-the slot 6 admitting of itsbeing moved inward towardthe center of the table B, or outward'fro n the same, the not 0 being unscrewedfor the adjustment, and afterward screwed tight to .hold the parts together.

If desired, the guide-strip E may have a groove, f, I l

on its top side, as seen in fig. 6, toreceive the ends of pins, g g, projecting from the lower ends' of the modification shown in fig. 8.

,The-gnide-stri-p E instead ot'jbeing "of; elliptical jaws b b offthe'swivel-plate J as represented in fform, a s' represented in the drawing, may be ot'an'y" otherform'desired, by having a single pin, g, tot-he swivel J as represented in fig. 9.

What I claim as myinvcntion, and desirejto secnre byLettcrsBatent, is-5' 1. The combination and arrangement ot the guidestrip E on the clamping-plate D, with the tabldB, for regulating the form of the print, 'substantiahyin the manner above described.

2. The combination of the revolving cutterF, shaft G, swivel-plate J the sliding bar L, and center-pin: K, having a nut, O, the said parts being constructed, arranged, and operating in relation to each other .an'd

to the guide E, substantially in the .manner and for the purpose set-forth.

3. The combination and arrangement of the spring I Q and rods RS,- with the stand A and sliding bar L,

substantially as and for the purpose above described. 1n testimony that the above is myinvention, I have hereunto set in y'hand and afiixed my seal this 16th:

day of May, 1870.-
