PAPER-CARTON OPENER.

Application filed November 13, 1914. Serial No. 871,903.

To all whom it may concern:

Be it known that I, ARTHUR I. PLATT, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Paper-Carton Openers, of which the following is a specification.

This invention has for its object to provide a simple and inexpensive implement especially adapted to open corrugated paper cartons and fiber cases without injury'to the container, so that it can be used again, and without danger of injuring boxes or articles within the container.

It is of course well understood that in shipping generally. and especially in shipping articles contained in paper boxes, corrugated paper and pastebcard or fiber cases have largely taken the place of wooden boxes. These corrugated paper or paste board cases are commonly designated as cartons and conslst of a container, so called,

which is usually a lidless box of the knockdown type, and an independent lid which ordinarily tucks into the container. The function of the present invention is to cut the lid out entirely or to cut it on three sides, leaving one side to serve as a hinge, but

without injury to the container, so that it.

may be used again, and with perfect safety to the contents of the container.

"With these and other objects in View I have devised the novel paper carton-opener which I will now describe, referring to the.

accompanving drawing forming a part of this specification and using reference charactors to indicate the several parts.

Figure 1 is a side elevation of my novel implement; Fig. 2 an elevation as seen from the right in Fig. 1; Fig. 3 a longitudinal section corresponding with Fig. 1; Fig. 4 a section on the line 4-4 in Fig. 1, looking in the direction of the arrows, and Fig. 5 is a View illustrating the operation of the implement in opening a carton, which, however, is not necessarily placed in the position shown.

My novel implement comprises a cutter 10, a shoe l1 and a handle 12. The handle is shown as provided with a recess 13 in which to carry extra cutters, the recess beingwclosed by a screw cap 14. The handle is provided at its other end with a slot 15 to party receive the cutter and with a ferrule 16 having a slot through which the cutter passes. The rear end of the cutter is shown as provided with a slot 17 and its front side with a notch 18. A pin 19 passing through the ferrule, the handle and slot 17 retains the ferrule securely in place on the handle and also centers and steadies the cutter in use. The notch is visible through an opening 20 in the ferrule and permits the operator to engage the cutter and move it upward or downward for convenience in making an adjustment.

The special construction of the shoe is immaterial so far as the principle of the invention is concerned. I have illustrated a shoe consisting of two plates of sheet metal blanked out and formed to shape. The front ends of the central portion of these plates have formed therein half sockets which together form a socket 21 which is threaded to receive a set screw 22, the plates lying in contact above and below the socket and being secured together by rivets 23. Back of the contacting portion of the plates is a vertical guideway 24C for the cutter which passes into the apex of the channel in a plane m dway between the sides of the channel. The rear end of the guideway is closed by a filling plate 25, rivets 23 passing through the plates of the shoe and the filling plate. Above the guideway the plates are bent at a right angle and form cars 26 which are riveted to the ferrule. Below the guideway the plates of the shoe are bent outward at a right angle to each other to form an angular channel 27 adapted to receive the corner of a carton. as clearly shown in Fig. 5. I preferably shape and form the plates so that the channel will lie obliquely instead of at a right angle to the axis of the handle, so that in use with the channel lying parallel with the edge of a carton to be opened, the

handle will lie at an obtuse angle to the channel and to the edge of the carton and will incline backward away from the operator, which adds greatly to the convenience of the operator in using the implement. The front ends of the sides of the channel are curved outward, as at 28, so. as to permit the channel to ride smoothly over the cornor-of a carton. The edge of the cutter is inclined forward and upward from its rear end, leaving a sharp angle at the rear end to penetrate the carton. The front end of Patented Feb. 23, 12115;

TOO

Illlli the cutter above the edge is shown as cut away, leaving a shoulder 29. The cutter is operation of this implement is concerned, it being equally operative upon the various makes and styles of cartons in general use. The operator places the implement at the rear of the edge to be cut, forces the rear end of the cutter through the lid, the edge ofthe carton fitting closely in the channel,

and then draws the implement forward, as .indicated 1n Fig. 5, until one side of the lid is entirely cutout. This operation may be I repeated on all four edges of the carton to I handle and the shoe and passing into the remove the lid, or upon three sides only if preferred, leaving one edge of the lid to serve as a hinge therefor. In changing from heavy to light cartons, or vice versa, the cutter may be adjusted by loosening the set screw and raising or lowering the cutter as may be required, and then looking it in the guideway again by tightening up the set screw.

Having thus described my invention I claim:

1. An implement of the character described comprising a shoe having an angular channel adapted to receive the edge of a carton, a cutter passing into the apex of the channel in a planemidway between the planes of'thesides of the channel, and a handle lying at an obtuse angle to the channel. I v I 2. An implement of the character described comprising a shoe having an angular channel adapted to receive the edge of I a carton, a handle lying-at an obtuse angle to the channel and a cutter socketed in the apex of the channel in a plane midway between the planes of the sides of the channel.

3. An implement of the character described comprising a shoe having an angular channel adapted to receive the edge of a carton, a. handle, a cutter socketed in the handle and the shoe and passing into the apex of the channel in a plane midway between the planes of the sides of the channel, and means for locking the cutter at any required adjustment.

4.. An implement of the character described comprising a shoe having an angular channel adapted to receive the edge of a carton and a cutter passing into the apex of the channel in a plane midway between the planes of the sides of the channel.

5. An implement of the character described comprising a handle, a shoe having an angular channel adapted to receive the edge of the carton and lying in a plane oblique to the handle and a cutter socketed in the handle and the shoe'and passing into the apex of the channel.

6. An implement of, the character described comprising a shoe formed from plates of sheet metal shaped to form a. guide-way, a channel adapted to receive the edge of a carton and a threaded socket, a cutter in the guideway and passing into the apex of the channel and a set screw in the socket by which the cutter is locked at any required adjustment. r

7. An implement of the character described comprising ashoe formed from plates of sheet metal shaped to form aguide-way, a channel adapted to receive the edge of a carton and a threaded socket, a cutter in the guideway and passing into the apex of the channel, a set screw 7 in the socket by which the .cutter is locked at any required adjustment, and a handle lying obliquely to the channel in the shoe.

In testimony whereof I aflix my signature in presence of two witnesses.
