Specification of Letter: Patent. Patented flgv, 28, 1911,

Application filed June 29, 1911 Serial No. 638,085.

particularly to that type of machine illustrated in my prior application Serial No. 612,566, filed March 6,.1911.

The main features of the machine, as far as the slitting and rewinding operations are concerned, are substantially the same .as in the machine illustrated in the application above referred to.

The main object of my present invention is to facilitate the subdivision of a tube u on which the material is rewound, the sections into which the tube is subdivided corresponding in length to the width of the separate strips of rewound material, so that a long tube-may be placed in the machine, cut

to the proper lengths, and thematerial rewound, each strip of rewound material being upon a separate section of the tube.

A further object of my invention is to utilize the pressure roller of the machine which normally engages with the material during the rewinding, as a means for forcing the tube cutters into the tube.

A still. further object of my invention is to facilitate the raising and lowering of the pressure roller during the placing of the tube cutters or the removal of the completed rolls and to permit the locking of the pressure roller in raised position.

The invention consists in the arrangement and combination or parts hereinafter particularly described and pointed out in the claims- Reference is to be had to the accompanying drawings, which form a part of this specification'and in which similar reference characters indicate corresponding parts in the different views. I

Figure 1 is an endview of a machine constructed in accordance with my invention; Fig. 2 is a vertical section through the upper central portion of the machine showing the tube cutters in operative position; Fig. 3

is a top plan view of a portion of the machine, showin the arm raising mechanism; Fig. 4 is a sectlonal detail of a portion of the armraising mechanism; Fig. 5' is a top plan View of a portion of the tube cutters; and Fig. 6 is a face view of a portion of the machine showing the tube cutters.

In this machine illustrated, there is employed a main frame 10, serving to support a roll A of .paper or other similar material to be unwound, slitted and rewound and also serving to support guide rollers 11,

rotary cutters

12 and 13, a reel 14 and friction rollers 15. The paper passes from the roll over certain of the guide rollers, thence between the cutters and eventually on to the reel. The reel is supported by two friction rollers 15, which are rotatedin the same di rection, and the roll of rewound material on the reel is held down by a pressure roller 16 which is also positively driven. The pressure roller is movable vertically and is carried by the arms 18 pivoted to two pivoted arms 19.

.I do not claim in this ap lication any patentable features in the details of the ma chine so far described. The machine serves to cut the paper into strips of any desired width, and a special feature of my presentimprovements relates to a se aration of the tube upon which the material is rewound, into sections. In carrying out this part of my invention, I place a tube 13 on to the reel 14, the tube being preferably of paper and constructed in the same manner as an ordinary mailing tube. In the rear portion of the machine I provide a transversely extending rod, and pivoted to this rod, are a plurality of arms 21 adjustable lengthwise of the rod and each adaptedto be locked to the rod by a set screw or other similar device. Each arm has journaled upon the under side thereof a rotary cutter 22, which, when the arms are swung forward, will engage with the upper side of the tube upon the reel. The arms 21 are adjusted to such positions along the rod 20 that the cutters 22 will be at the same distance apart as the main pairs of cutters for the paper. The cutters 22 come directly upon the upper side of the tube and beneath the-pressure roller 16, and each arm has a seat 23 for the roller.

In using my improved machine, a tube tent for which the cutters may enter the tube and to prevent them from being dulled on the reel 14, the two end arms 21 may each be provided with small rollers 24, as' shown in Fig. 6, so as to engage with the tube upon opposite sides of the cutter and limit the cut of the latter. When the cutting operation is finished, the pressure roller is ralsed and the arms 21' thrown back to the position shown in doi ted lines in Fig. 1. Here they may rest against a small cross bar 25.

- To facilitate the raising and lowering of the pressure roller, I provide the arm- 19 with a segment 26 and mount a pinion 27 in mesh with this segment. The pinion is mounted on a stub shaft 28, which shaft also carries a wheel 29. The wheel is rotated by means of a handle 30, which extends forwardly to the front part of the machine, so as to be within easy grasp ofthe operator. The handle may be secured to the wheel at any one of the plurality points by means of sockets 31 in the wheel and it may be locked in any socket by means of suitable screws 32. By pulling down on the front end of the handle, the pressure roller and arm 19 may be readily raised the required distance, inasmuch as the pinion has a smaller radius than the segment, and the handle 30 is of greater length and greater leverage than the arm 19. The handle 30 is, of course, used for raising the pressure roller'to permit the removal of the rolls of rewound material. For locking the pressure roller in raised position, I provide a catch 33 mounted in a socket 34 carried by the main frame. The handle may be sprung out and slipped beneath the catch, or the 'catch may be longitudinally movable within thesocket. I

Various changes may be made in the details of construction of my improved machine without departing from the spirit of my invention.

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