' EMPROVEMENT IN PAPER-BOX MACHINES.

Specifioation forming part of Letters Patent No. 1113,65 3, dated March 17, 1874 application filed February 7, 1874.

To all whom it may conccrn:

of YVestville, in the county of N ew Haven and State of Oonnecticut, have invented anew and useful Improvement in Paper-Box Machines; and I do hereby declare that the following is a full and exact description of the same, reference-being had to the accompanying drawings and to the letters of reference marked thereon.

This invention is especially designed for making blanks for match-boxes, the same being formed from a continuous strip of paper, which, in passing through the machine, is suitably scored and cut into proper form; and its novelty consists mainly in the employment of certain auXiJiary rollers of peculiar construction, for the purpose of forcibly separating from the uncut end of the strip held by the scoring and cutting rollers the cut portions which have been imperfectly severed by the knives, thus insuring the perfect and complete separation of the parts, as will be fully described hereinafter.

In the drawings, Figure 1 represents a perspective view of the entire machine; Fig. V2, a central sectional elevation; Fig. 3, the manner of cutting the strip; Fig. 4, a perspective view of the blank, and Fig. 5 an elevation of of the cutting and scoring roller.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its construction and manner of operation.

A represents any suitable frame work adapted to support properly the moving parts of the mechanism. b represents the shaft, to which the main power is applied in any suitable manner. It is supported in proper boxes in the frame-work, and is provided at one end with the gear-Wheels bl 112, the first of which,

bl, engages with the similar gear-wheel 01 upon the corresponding end of shaft c, and the second with the gear-wheel dl upon the end of shaft (Z. The shaft Z) is provided with a cylindrical roller, B, and the) shaft c with central segmental projections 02 and the end projections 03 03, as shown. This shaft rests in proper boxes vertically adjustable in the guideways of the frame-work, and held in place by the coiled springs c4 04, which are themselves held I in position by studs 05 05, projecting from the Be it known that I, EBENEZER B. BEECHER,

securing-bar cs, as shown. By means of these springs the upper roller is permitted to yield vertically if a substance of unusual thickness passes between the rollers. D represents the pressure-roller, against which the knives act in outting. It receives motion through its gear-wheel dl from the gear-wheel 122, and itself communieates motion by means of its gearwheel dz, Fig. 2, to the corresponding wheel 82 upon the shaft e. E represents the roller, provided with the scoring and cuttin g knives. These are suitably arranged, as indicated in Fig. 5, to make proper indentations upon the folding lines, and to separate the parts upon the lines to be out. The roller D rests upon the roller E, and presses the pasteboard against the knives, this pressure being regulated by means of adj usting-screws in thebar, as shown.

It will be observed that the cireumference of the gear-wheel D2 is one-third of that of the gear-wheel dl, With which it engages, and consequeutly it will be understood the shaft b,'

and also the shaft c, which move with it, have a speed three times more rapid than the shafts d and e, which move together.

The operation is as follows: The machine having been put Ain motion, one end of a strip of pasteboard of proper width is introduced into the machine between the cutting and the pressing roller. The action of these rollers draws in the pasteboard, soores and cuts it, and delivers the blanks thus made, and the waste portions upon the other side. The knives upon the Cutting-roller are themselves adapted in form to cut the completeblank but in practioe it is found impossible for any length of time to make them cut out perfectly the corners, so that the waste portions will not adhere thereto. To remedy this difficulty I employ the auxiliary rollers described, which operate in the following manner: The end of the strip having passed between the outting and pressing rollers, then passes through between the auxiliary rollers b c before the blank is severed from the strip. It is not, however,

acted upon by these rollers, as the two are not in contact until the blank is completely severed from the strip, as far as the knives can accomplish this result, at which time the central segmental projection of the roller o z masaz reaches the pasteboard in its revolution, and, in connection with the lower roller, clamps the still adhering` blank, and by means of the increased velocity of the rollers, the same is forcibl y separated from that part still held by the more siowly-moving cutting' rollers. When the blank has been thus separated from the end of the strip, the waste portions w will be left projecting', as shown in Fig. 8, their rear sides still uncut and attached to the strip. As soon, however, as these parts are sevcred from the strip by the continued revolution of the cutting-rollers, they are seized in a similar manner by the end projections of the roller c, and forcibly separated from the other part.

The central segmental projection, it will be observed, has that edge which, in its revolution, strikes the pasteboard, beveled or inclined, so that no injury is done by its rapid inovement.

The parts of the machine are, of course, adapted to work in harmony with each other.

The clamping-rollers take the blank and waste portions only after they have been cut from the strip, and the cutting rollers are adapted to cut a blank at each of the revolutions of the clamping'-rollers.

By means of the adjustment described, the pressure of the upper roller, relative to the knives, can be regulated at will, and the clampiug-rollers are adapted to act with an clastic pressure.

The machine as a whole is quite simple in its construction, and yet very effective for the purpose for which it is designed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the cutting-rollers D E with the auxiliary rollers b c, adapted by segmental projections and a more rapid revolution to clamp at intervals the blank and waste portions and separate them from the strip, substantially as described.

2. The -roller c, provided with central segmental proj ection 02 and the end segmental projections 03, relatively arranged as described, to clamp at properintervals the blank and waste portions, as set forth.

3. In a machine for cutting box-blanks, the combination of the following elements: First, the cutting-rollers, adapted to draw in, cut, and deliver the strip; second, auxiliary rollers, adapted to receive the end of the strip and forcbly separate the same from the main part third, the gearing connecting the two rollers, adapted to give a more rapid revolution to the auxiliary rollers than to the cutting-ro11ers,bnt having a certain fixed relation thereto, as described.

This specification signed and witnessed this 27th day of January, A. D. 1874.
