MACHINE FOR TRIMMING THE ENDS OF PAPER VESSELS.

SPECIFICATION forming part of Letters Patent No. 335,078, dated January 26, 1886.

Application filed July 21, 1884.

To all whom it may concern:

Be it known that we, HENRY W. LEONARD and JOHN STEvENs, residing, respectively, at Syracuse, in the county of Onondaga, in the State of New York, and Port Byron, in the county of Cayuga and State of New York, have invented new and useful Improvements in Machines for Trimming the Ends of Paper Vessels, of which the following is a specification.

This invention relates to an improvement in machines for trimming the ends of paper pails and similar hollow vessels made of paper-pulp or similar material, and has for its object to produce a machine by which the operation of trimming the paper pail or vessel can be rapidly and uniformly effected.

Our invention consists, to that end, of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal section of our improved cuttingmachine. Fig. 2 is a top plan view thereof, and Fig. 3 an end elevation of the same.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the machine.

B represents the base-plate, supported on the frame A and provided with two standards, I) b, having bearings 12' b at their upper ends, in which is journaled a horizontal shaft, 0.

G rep resents a driving-pulley mounted on the shaft 0, between the bearings b b.

D represents a mandrel secured to the projecting end of the shaft 0, and adapted to receive and hold the paper pail or other vessel which is to be cut.

at represents a number of annular bands, rings, or hoops of soft metal, preferably Babbitt metal, applied to the periphery of the mandrel D at the points where the cutters operate against the same.

E E represent-two circular-cutters mounted, respectively, on arbors e e, which are secured to the upper ends of standards F F. The latter rest with their lower ends on a guide-bar, G, which is arranged parallel with the shaft 0, on one side of the mandrel D. The guide-bar supporting Serial No. 138,383. (No model.)

G is provided with a longitudinal dovetail groove, 9, and the lower ends of the standards F F are provided with dovetail tenonsf,which slide in the grooveg, so that the standards F F and cutters can be adjusted parallel with the shaft 0, in order to bring the cutters in contact with theinandrel D at varying distances from the end thereof. The standards]? Fare secured in the dovetail groove of the guide-bar G by setscrews f or other suitable means.

H represents a dovetail guide arranged at right angles to the guide-bar G and below the same, and secured to the upper side of the supporting-frame A.

h represents dovetail lugs formed on the under side of the guide-bar G and engaging with the dovetail guide H, so that the guidebar G, standards F F, and cutters secured thereto can be adjusted toward or from the mandrel D by moving the guide-bar G in one or the other direction on the dovetail H.

I represents a feed-screw journaled in bearings i on the dovetail guide H, and arranged centrally on the same at right angles to the guide-bar G.

J represents a screw-threaded lug formed on the guide-bar G and engaging with the feedscrew I, so that by turning the latter the guideba-r G is moved on the dovetail guide H in one .or the other direction, as may be desired.

The feed-screw I is provided with a handcrank, K, or hand-wheel,for turning it.

When the machine is used for cutting or trimming the ends of paper pails, the mandrel D is made tapering, as shown, to correspond with the taper of the pails to be cut, and the hoops d are arranged in the proper places on the mandrel to receive the thrust of the cutters E E in cutting or trimming both ends of the pail. The cutter E is made larger in diameter than the cutter E, so that both cutters are brought simultaneously in contact with the pail on the mandrel.

The pail to be cut is placed on the mandrel, and the cutters are moved against the mandrel by the feed-screw I. The mandrel is rotated by means of a belt running around the pulley G, and the rotary movement of the pail is imparted to the cutters as soon as they are brought in contact with the paper pail on the mandrel. The cutters readily penetrate the pail, and two circular cuts extending around the pail are produced in this manner expeditiously. As the cutters are secured to the guide-bar G, the pails are all cut to the same length.

If it is desired to cut paper pails, or vessels in two in order to produce shallow vessels for instance, cuspidors-one of the cutters is arranged centrally on the guide-bar G, so as to out against the central ring, (2. The rings d d being made of soft metal receive the thrust of the cutters without injury to the latter, and the rapid movement of the cutters tends to keep their cutting-edges sharp.

We claim as our invention 1. The combination, Witha revolving tapering mandrel, of two circular cutters of different diameters adapted to bear simultaneously 20 against the mandrel, substantially as set forth.

2. The combination, with a revolving mandrel, D, of a circular cutter attached to a standard, F, a guide-bar, G, arranged lengthwise of the mandrel and supporting the stand- .2 5 ard F, a guide-bar, H, arranged transversely to the guide-bar G and supporting the latter, and a feedscrew, I, substantially as set forth.

Witness our hands this 7th day of May, 1884.
