MACHINE F OR CUTTING PAPER-STOCK.

SPECIFICATION forming part of Letters Patent No. 678,837, dated July 16, 1901.

Application filed July 11, 1900.

To all whom it may concern:

Be it known that I, CHARLES W. GRIFFIN, a citizen of the United States of America, residing in Riegelsville, in the county of Warren and State of New Jersey, have invented new and useful Improvements in Machines for Cutting Paper-Stock, of which the following is a specification, reference being had to the accompanying drawings and characters of reference marked thereon.

The object of myinvention is to provide a construction of machine for cutting paper-stock of all kinds other than wood, thus comprising cotton and woolen rags, bagging, jute, butts, rope, 850., which shall be strong, easily operative, effective in operation, comparatively inexpensive in cost of manufacture, adj ustable and convenient for cleaning and repairing, and a machine which will perform more than one cutting operation, reducing the product to such size that it can be most economically handled and manipulated in the following operation for converting the material into paper, doing away with the operation of recutting and rehandling, and a machine which will rapidly and with great economy of power reduce the material to the desired requirements.

I accomplish the object of my invention by the construction herein shown.

In the accompanying drawings, in which like characters of reference indicate like parts, Figure 1 is a side elevation of the machine constructed in the preferred form, the crossthe adjustable bed being shown in section.

Fig. 2 illustrates a modification in the method of adjusting the adjustable bed wherein inclined ways are used instead of a pivotal support, as shown in Fig. 1. Fig. 3' is a perspective view illustrating another modification. wherein the adjustable bed is moved vertically by the employment of wedge-shaped pieces, and Fig. 4 is a view illustrating a modification wherein the bed is moved by a series of threaded rods.

In detail, a and 6 indicate the supportingframe; 0, adjustable bed or blade-support; cl, rotating blade-carrier; e, feed-roll; f, blades mounted in the rotating cutter-head; g, blades in adjustable bed; h, first stationary stun No 23,230. (No model.)

blade-support; 1', blade mounted thereon; j, hopper or feed-table; 7c, adjustable support for the free end of the adjustable bed.

The construction and operation of my machine are as follows:

A frame 5 is suitably supported upon a frame a, and while I prefer that these two parts be made separately it will readily be seen that they may be made integral, if desired. The cutter-head cl isrnounted ona suitable shaft, which shaft has suitable bearings and is provided with any convenient driving means. The cutter-head d is provided with blade-receiving recesses, in which the blades f are adj ustably secured, preferably by the employment of bolts 1 or other suitable locking means and by the employment of adj usting-bolts 2, passing through a suitable opening in the head and through a threaded nut'or part Z and bearing against the heel of the blade, so that by turning the bolts 2 the blades f may be adjusted toward or from the stationary blades. Suitable recesses are provided at the free end of the adjusting-bolts, so the same may be engaged by a wrench when desired.

A hopper or feed-table of any suitable construction may be employed, and a spur-provided feed-wheel e is arranged to feed the material to be operated upon gradually to the cutter. 1'

The machine is provided with a stationary cutting-blade 71, mounted upon a support h, against which blade the first cutting operation is performed. This blade is adjustable in like manner to those first described.

The adjustable bed 0 is preferably constructed and arranged as shown in Fig.1, it being mounted'near one end portion upon pivots, trunnions, or a shaft on and is free to be turned on its pivotal support to carry its forward portion toward or from the rotary cutting-head. This movement 1Z. e., the raising and lowering-may be accomplished in any convenient manner, and for the purpose of adjustably maintaining the adjustable bed in the desired position I prefer to arrange a bolt is, adj ustably mounted in a rock-shaft n, which rock-shaft is adapted to be rotatedto carry the bolt is from its normal position, as indicated in full lines in Fig. 1, to the posibolt 75 out of the path of the adjustable bed' and afterward returning it to its normal position I employ a rod z, attached to an arm 2, which arm is fixed to the rock-shaft 'n, the

free end of the rod 2 being carried to a convenient position for manipulation. In this position the machine may be easily cleaned or repaired. To raise and lower the bed a, Fig. 1, a lever is mounted at s. I prefer that two stationary blades 9 be mounted in the adjustable bed 0 and that they, be secured in position by the employment of wedge-shaped pieces 0, which pieces are arranged in recesses having the wall opposite the bolt formed at an incline, the pieces 0 being inclined also, and threaded rods 19 extend from the wedge-shaped pieces 9 through the bed and are provided at their free ends with nuts. Threaded rods are also provided which bear against the heels ofthese blades, so that the blades may be adjusted toward and from the rotary cutting-blades, as desired, and after being properly adjusted in the desired position they are locked therein by tightening the nuts upon the rod p, thus drawing the wedge-shaped pieces ointo the recess and causing them to bear firmly against the blades, and thus prevent all disarrangement. Any convenient means for moving the adjustable bed toward and from the rotary cutting-head may be employed.

As a modification of the construction illustrated in Fig. 1 I show in Fig. 2 a construction wherein the adjustable bed is mounted upon inclined ways and a threaded rod 7 is suitably connected with the bed 0 and passes through a nut s, which rod is provided with a hand-wheel t, and it will readily be seen that if the hand-wheel is revolved the bed a will be moved up or down the incline, and thus adjusted toward or from the rotary cutting-head.

In Fig. 3 I illustrate another modification wherein the supporting-bolt k is mounted in a nut U1, which nut is inclined or wedgeshaped upon its lower surface and rests upon a bifurcated block 41, which latter has its upper surface inclined and is suitably connected with a threaded rod 7', passing through a suitable nut and provided at its free end with a hand-wheel or crank, so that a revolution of the rod will move the wedge -v and cause the nut to to slide up or down upon its incline face, thus carrying the bolt is upwardly or downwardly, and with it the bed 0, the whole being mounted upon a rock-shaft or body to, provided with trunnions, so the adjustable supporting mechanism may be turned out of the path of the bed 0, as described with reference to the construction shown in Fig. 1.

In Fig. 4 I illustrate another modification wherein the adjustable bed 0 is carried vertically toward or from the rotary cutter-head,

this .being accomplished by the employment of four threaded rods w, each provided with a bevel-gear, and rods y being provided with suitable gears to intermesh with the first-described gears, so that a revolution of the shaft y will cause a revolution of all the shaft and rods, and such rods having threaded connection with the bed 0 it will readily be seen that as these rods are revolved the bed will be carried upwardly or downwardly, dependent upon the direction of revolution of the operating-s'haft y.

It will now be seen that by the employment of the construction illustrated herein the ma-. terial is first operated upon by the rotary knives cutting it against the first stationary knife i and that the material is then carried downwardly and is out against the first stationary blade in the adjustable bed and then against the second stationary blade in said bed, so the material is acted upon substantially three times, or, in other words, there are three distinct cutting operations performed with only one handling of the material.

It will readily be seen that the number of both rotating and stationary knives may be increased or diminished, as may be desired.

The adjustable bed normally occupies a position substantially horizontal and by reason of its weight is held by gravity from being accidentally moved toward the rotary cutter, so that it becomes unnecessary to provide any means for forcing it away from the cutter.

Having therefore described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a machine for cutting paper-stock, the combination with a suitable supportingframe, of arotary cutter-head mounted therein, one or more blades mounted in the cutterhead, a bed pivotally mounted at one end upon the frame, cutting-blades secured in the bed, a rock-shaft journaled within the frame and below the said bed, means on the rockshaft arranged to bear against and support the said bed, and means to rock the rockshaft.

2. In a machine for cutting paper-stock, the combination with a suitable frame, of a rotary cutting-head mounted therein, one or more blades mounted on the cutter-head, a swinging bed pivotally mounted at one end upon the frame, cutting-blades secured withfrom the cutter-head, blades in the adjustable bed, a stationary support h across the frame above the adjustable bed, and a cutter or 'blade'mounted on the support, substantially as described.

4. The combination in a machine for cutting paper-stock of a suitable frame, a rotary cutting head, having one or more blades mounted therein, a stationary adjustable bed having one or more blades mounted therein, threaded rods arranged to bear against the heels of the blades and wedges arranged to lock said blades in position when adjusted, substantially as shown.

5. The combination in a machine for cutting paper-stock, of a suitableframe, a rotary cutter-head mounted in the frame, three blades mounted in the cutter-head, and three stationary blades, arranged one adjacent to the point where the material is fed to the machine and the other two near to each other and remote from and below the point of feed, substantially as shown.

6. In combination with a rotating cutterhead mounted in a frame, in a machine for cutting paper-stock, a blade-carrying bed mounted in said frame, and rocking means for adj ustably supporting said bed, said means being arranged to be moved out of the path of the bed whereby it will automatically move from its normal cutting position, substantially as shown.
