SPECIFICATION forming part of Letters Patent No. 551,130, dated December 10, 1895.

Application filed. July 31, 1893. Serial No. 481,962. (No model.)

T0 at whom it may concern.-

Be it known that I, GEORGE IV. MILES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cut-Offs for Paper-Box Machines and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of the invention is to construct a paper-box machine with a cut-off which shall be automatic in its operation and which may also be operated by devices independent of the principal cut-off mechanism.

In the accompanying drawings, Figure 1 represents a perspective View of a paper-box machine having my improvements as in use when applying a paper strip to the sides and ends of a box. Fig. 2 is a side view of the machine as it appears when used for cutting the paper strip applied to the top of a box. Fig. 3 is a sectional view illustrating the worm-gearing through which the shaft which carries the box-form is driven and other details. Fig. 4 represents two parts of a cam and a slotted plate which are employed in connection with the shaft which carries the box-form. Fig. 5 is a plan view illustrating an adjustable platform. Fig. 6 shows a crosssection of a hollow bar or housing in which a worm-shaft is mounted. Fig. 7 is an end view showing the end of the machine on which the cutters are mounted, with a platform in position for applying the paper to the top of the box. Fig. 8 shows a section of a cam on a shaft on which a box-form is mounted. Fig. 9 illustrates a swivel connection of a rod with an arm of the cutter-shaft.

A designates the supporting-frame, which is provided with two parallel rods or bars B, to which are suspended the hanger-bearings C for the journals cl of a ribbon-spool D. E indicates the ribbon or strip of paper which passes from said spool through the guides F over the roll G, which rotates in a paste-box G", then over a guide-roll H and over a stationary cutter R to the box on which the paper is to be pasted. The said box is placed on a box-form I, which is removably mounted on a rotative shaft J, which has bearings 7s on-a horizontal hollow bar or housing K, secured to the supporting-frame by bolts L, passed through a slot Z in an arm or lug it. (See Figs. 6 and 7.) The guide-roll H has two heads connected by transverse wires, so that as little of the paste-surface of the paper ribbon as possible shall come in contact with said roll, the latter being mounted in bearings carried by the frame A. The operator manipulates the paper ribbon so as to paste it on the box as the shaft J revolves.

Mounted at one end of the frame A is a cutter-frame, which has two side parts 1, which are adj ustably connected with'two inclined rods 2, which are made fast at their lower ends to a cross-bar of the frame A, and the cutterframe may be adjusted upward or downward on said rods 2 by means of the set-screws 3, to adapt it for boxes of different sizes.

To a cross-bar of the cutter-frame is adj ustably secured a stationary cutter-blade R, and in the upper part of said frame is mounted a cutter-shaft Q, from which extend the curved arms g, which are adjustablysecured to the shaft Q by set-screws. To the free ends of the arms q is secured a cutter-blade R, which is inwardly inclined to correspond with the bevel of the cutting-edge of the stationary blade R, and also to make a shearing cut.

011 one end of the shaft J is secured a cam, which is made in two parts, the central part being formed of a circular disk J, which has a rabbeted or flanged edge and is fast on said shaft J. The other part of said cam is formed of a ring-disk M, into which the disk J is fitted, as shown in Fig. 8. A thumb-screw M, in a threaded hole in the disk J, is used to tighten the ring-disk M thereto, and a screw M passed through the disk J so that the head of the screw will bind the ring-disk, serves to hold the two parts of the cam together when the thumb-screw is turned to loosen the ring-disk to adjust it in position on the circular disk.

The ring-disk M is formed with a notch or cavity m and a cam-form m, and the ringdisk is adjusted on the circular disk with the N indicates a slotted plate having at oneend a stud n, on which is placed a frictionroller n At the opposite end of said plate is a socket 01 through which is passed one end of a rod 0, which is connected with a cylindrical bearing 1f, which moves in the slot a of the plate, and a spring n is placed on the rod 0, between the socket n and the cylindrical bearing. The upper end of the rod 0 is held in a sleeve P, which is adjustable on the rod and is swiveled to or loosely connected with a crank-arm q of the cutter-shaft Q. The plate N is movable connected with the shaft J, the latter extending through a slot 72 in said plate to allow a longitudinal movement of the rod 0, and the cam M J is secured to the outer extremity of said shaft after the shaft has been passed through said plate.

Rotary motion is imparted to the shaft J, which carries the box-form and the cam M J, through a worm-shaft O, which is in gear with shaft J and is mounted in the hollow bar K, as shown in Fig. 3, a wheel on shafts O and belting being indicated by 0 At the box-form, with the box thereon, is rotated, the cam, moving against the roller 71 on plate N, draws the rod 0, which is connected with an arm on the shaft of the cutter R, and the cutter is thus raised the required height, and when the roller slips from the cam, as the cavity m is reached, the cutter R descends automatically by gravity and severs the paper ribbon.

S indicates a platform which is used to hold the box in position for pasting paper on the top. (See Figs. 2 and 5.) The said platform is supported by a bracket U, which is adj ustably secured to a vertical shaft V, mounted in bearings carried by the frame A. The said platform is secured to the bracket by means of a thumb-screw T, passed through ahole in the bracket and through a lug on the lower side of the platform. to the shaft V by means of a screw t and a clamp 15. \V indicates a right-angular plate having a slot 10, said plate being adjustably secured in position on the platform to hold the box, placed thereon, in the right relative position for applying the paper strip. The plate V is secured by a thumb-screw w, which is passed through a cleat s of the platform and a slot w of said plate. A set-screw t is carried by an arm a of the bracket, said screw forming an adjustable stop for contact with the main frame when the platform is swung to the front of the machine for use. hen not in use, it is in a depressed position at one side of the machine.

lVhen the paper is to be pasted to the top of the box, the box-form with the box thereon is removed from the shaft J, the clamp 25 on the shaftV is loosened, and the platform is raised, the clamp is again tightened and the platform is swung around to its proper p0- The bracket is secured sition in front of the machine. The box-form with the box is then placed on the platform, its position being regulated by the plate W and cleat s and the paper is applied to the top of the box by the operator. Cut-off mechanism, independent of the shaft J and its driving mechanism, is provided and is employed for cutting the paper when applied to the top of the box. A foot-treadle X is pivoted to a plate m, secured to the floor or to the base of the machine, and a cord Y is connected with the treadle, passed over a pulley 3 mounted on the bar K, and connected at with the rod 0. I

The cutter B being held in its raised position by the spring n on the rod 0, the operator presses the treadle X with his foot when the paper is to be cut, thus moving the said rod upward and partly rotating the cuttershaft, so that the cutter-R descends and severs the paper strip.

The cutter-frame being adjustable on the fixed oblique rods 2, and the cam with the adjustable ring-disk, formed wit-h the cavity m, are considered important features of the machine.
