ENVELOP-MAKING MACHINE.

To all whom it may concern:

Be it known thatI, PHILIP H. FARRELL, a citizen of the United States, and a resident of Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in Envelo )-Making Machines, of which the following is a specification.

This invention relates to the cutting mechanism for a machine for making envelops, bags and the like. Its organization comprises a rotating drum which carries one or more cutters, for cutting a sheet of paper or other material bearing on the drum, the said cutters being actuated by a stationary cam.

To exemplify the invention it is shown with a complete envelop making machine.

In the accompanying drawings which exemplify the invention Figure l is a partial vertical section of the invention, as on a line at, 00 of Fig. 2, Fig. 2 represents a plan View of Fig. 1, and partial section on the line 00, m. Fig. 2 shows a plan view of a blanking out drum. Fig. 3 shows an enlarged portion of Fig. 1 containing the knife, Fig. A is a plan view of Fig. 3 with a portion of the frame of the machine, Fig. 5 shows a partial end view and section of Fig. A on the line 00 00 Fig. 6 is a side View of Fig. 4. Fig. 7 shows an enlarged plan view of the machine with the envelops in their different stages of manufacture.

A frame is represented at A with the sides A, A It supports a spool B, in the bear ings a, for a sheet of material, paper and the like C. A roller D is journaled in the sides A, A of the said frame.

A rod E is held in the frame which supports a pair of loose sleeves E, that each have a groove 6. A rod E extends between the sides of the said frame and carries the supports E for the creasing rollers E A pair of hangers E extend from end of the supports E and encircle the rod E the bolts 6 clamping the hangers E in position.

A blanking out drum F is secured to a rotating shaft f, the ends of which are car ried in bushings F, which with the ring cams F are clamped to the sides of the frame A, by means of the bolts P. On the extension of the shaft f is secured the spur gear F Extending from the sides of the drum F are the journal bearings f which by means of the pins f carry the cutter supports F, from which latter extend the cut- Specifieation of Letters Patent.

ters f. Guide lugs f extend from the cutter supports 7 and straddle the cams F Above the rotating blanking out drum F is journaled a creasing roller G on the shaft g, which has extending from its circumferential surface the dies 9, that crease the sheet of paper or other material over the notches f in the surface of the drum F, the said notches being arranged to engage with the dies 9. The shaft 9 carries the spur gear G which meshes with the spur gear F A roller H is journaled in the sides of the frame A, and below the same is journaled a gumming wheel H, which rotates in a gum box H 011 the spindle it supported in bearings it extending from the sides of said box. The box is supported on a bracket H fastened to the lower plate A of the frame A. The spindle it carries a sprocket chain wheel k which is connected by the chain 71. with a sprocket chain wheel h on the shaft Z.

Across the width of the machine and se cured on shelves A" extending therefrom, is the shelf 1, that supports the aprons I and I A cover plate J is held over the said aprons, by means of the rod K. A pair of feeding rollers L and M are supported on the shafts Z, and m, the roller M having the flanges 022-, so as not to bear on the portion of the paper which has been gummed, or on its longitudinal axial line. The shaft Z is journaled in the bearings a and carries the spur gear 0, that meshes with the pinion O, on the spindle O The pinion O meshes with the spur gear 0 carried on the shaft which latter is journaled in the bearings a On the shaft 0 is fastened the supporting roller 0 and over the latter is journaled the gumming roller P on the spindle p, and has the slight projection 79 extending longitudinally across its circumferential surface. Over the roller P is the gumming roller P, which is driven by the projection 72 of the roller P. The roller 1? bears on the roller P, and the roller P bears on the roller P The roller P rotates in the gum box P The spur gear 0 meshes with the pinion 0 carried on the spindle O and the pinion O meshes with the spur gear 0 which is fastened on the shaft 0". The shaft 0 carries the cutting off drum Q, which has the slots Qlongitudinally across its circumferential surface. At the ends of the drum Q project the bearings Q for the spindles Q on which latter are carried the knife frames R with the knives R. The

knife frames R have the lugs R which straddle the ring cam S, that has the arms S, and by means of which latter is fastened to the sides A of the frame A. On the shaft is also fastened the disk T, from which are journaled on the spindles t the spur gears T, that mesh with the spur sectors T the latter being journaled from the disk T on the spindles t. A pin It extends from the side A of the frame and is located in the path of the sectors T On the spindles t of the spur gears T are fastened. the folding blades T that are arranged to bear on the paper or other material on the cutting off drum.

'A sector V is journaled on the pin V extending from the side A of the frame, and it has the teeth V that mesh with the teeth of the spur gear V The latter is fastened to the shaft V of the crank From the latter extends the arm V, that supports the holding blade V The sector V is arranged to engage with the cam WV on the shaft 0.

On the shaft Z is mounted the pulley L, and the sprocket chain wheel L which latter is connected by the chain L to the chain wheel F on the shaft To operate the invention the machine is driven by means of the pulley L. The paper or other material on the spool B is led under the roller D, and from thence passes between the creasing rollers E and loose sleeves E, by virtue of which it receives two creases that determine the width of the envelop to be produced. The paper, &c., then passes over the blanking out drum F, against which it is tightly held by means of the creasing roller G, the dies 9 of which form creases 21 therein to mark the length of the envelops. WVhile the paper is on the drum F the cutters f blank out the paper to the proper form for the envelop, as shown at 22 the drum rotating and the cutters actuated by reason of the lugs f engagingwith the ring cams F The paper is next led under the roller H, when the gumming wheel H gums one edge thereof. The paper then passes between the aprons I I and the cover plate J. The folders I and I of the said aprons bend the paper at the longitudinal creases, and the folders I and I fold the paper down to form the envelop of the proper width. The folder I being a little in advance of the folder I, the folded edge made by the folder I is under the edge of the paper folded by the folder I. The folded paper now passes between the feeding rollers L and M, gripping the paper between its longitudinal axial line and the longitudinal edges, so as not to pass over a three thicknesses of paper, and not to spread the gum. The paper then passes between the supporting roller 0 and the gmnming roller P, which are so proportioned that the projection 72 gums the paper across its surface, so as to be enabled to gum and close one end of the finished envelop. The proj ection p is gummed by means of the rollers P, P, P and gum pot P". Now the paper passes on to the cutting off drum Q where it is first cut by the knives R, the latter being actuated while the drum is rotating, by reason of the engagement of the lugs R with the ring cam S, which move the knives through the material and slots on the said cutting off drum and out again. The cut end of the material is then held in position by means of the holding blade V, which has a movement to and from the surface of the drum Q. Before the blade V leaves the material on the drum Q the folding blade T starts to turn over and fold the end. of the material to form the closed end of the envelop, securing the portion that has been gummed across its face in place. After the envelop is formed and folded as just described, the holder V moves away from the drum, and folder T turns to its original position shown in the drawings and the envelop is fed forward and cut off by one of the knives.

Having described my invention, I claim:

1. In an envelop making machine the combination of a blanking-out drum, means to feed a sheet of material to the drum, means to rotate the drum, a cutter journaled with 'the drum and arranged to operate through an opening in the surface of the drum, a ring cam adjacent to the drum, and lugs extending from the cutter straddling the ring cam.

2. In an envelop making machine the combination of a blanking out drum, having openings in its circumferential surface, means to feed a sheet of material to the drum, means to rotate the drum, lugs extending from the drum adjacent to said openings, cutter supports pivoted in the lugs, cutters extending from said supports, lugs on the supports, a ring cam in the machine straddled by the latter lugs so that they will follow the path of said ring cam during the rotation of the drum.
