UNITED STATES PATENT OFFICE.
FRANCIS M. KENNEDY AND EDWARD K. GAYLORD, OF OKLAHOMA, OKLAHOMA.
CORE-STRIPPER.
Specification of Letters Patent.
Application filed November 14, 1910.
Patented Mar. 1 1, 1911. Serial No. 592,192.
To all whom it may concern:
Be it known that we, FRANCIS M. KEN- NEDY and EDWARD K. GAYLORD, citizens of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented a new and useful Core-Stripper, of which the following is a full, clear, and exact description, reference being had to the annexed drawings.
The rolls of paper used on a perfecting printing-press are wound into a tubular metal core, usually common gas-pipe, and in using the paper the core is mounted revolubly to allow the paper to be drawn therefrom by the press. Before the paper is all unwound from the core it is severed, leaving a remnant of paper which is not suitable for use, but which must be removed from the core before a new supply of paper is wound on.
The object, therefore, of the invention is to provide a machine for removing the remnant of paper from the core.
Other objects and advantages of the invention will be set forth in the ensuing description.
Referring to the drawings :Figure 1 is a plan View of the complete machine. Fig. 2 is an end elevation. Fig. 3 is a rear elevation. Fig. 4 is a front elevation. Fig. 5 is an enlarged fragmental plan view of certain parts.
Referring to the several figures, in all of which like characters of reference designate like parts, the improved machine has a main supporting frame-work composed, in part, of the foot-sills 6, and a main wooden body or bed 7 which rests with its edge on said foot-sills. In addition to being secured to the bed 7, the foot-sills 6 have a wooden stringer 8 extending through them, and the two central foot-sills have a wooden base 9 mounted on them to support parts later referred to. A cast metal plate 10 is bolted to the rear face of the bed 7, and is provided with upwardly-extending integral arms 11 and 12 to support other parts. The arm 11 is bifurcated at its upper end, one arm 13 branching forward and the other arm 14 rearward, and the ends of said arms 13 and 14: are formed into bearings for a horizontal shaft 15 journaled at right angles to the bed 7. This shaft 15 forms an arbor for a circular cutting tool 16, which is mounted thereon in front of its supporting arm 13, and also with a belt-pulley 17 well back toward the rear arm 14:.
A cast metal frame 18, best shown in Fig. 5, is pivoted to the arms 13 and 14: on an axis line concentric to the shaft 15, said frame being pivoted to tubular sleeves 19 extending from said arms and embracing said shaft. The free edge of this frame 18- has a similar shaft 20 journaled within it, parallel to the shaft 15, this shaft 20 forming an arbor for a milling tool 21 which is mounted on its front end and exactly in line with the cutting tool 16 aforesaid. This shaft 20 is also provided with a beltpulley 22 similar to that of the shaft 15. A similar belt-pulley 23 is supported by the arm 12 and in line with the belt-pulleys l7 and 22. An electric motor 21 is secured to and supported by the wooden base 9, and the shaft 25 of said motor is provided with a belt-pulley 26. A belt 27 travels over the belt- pulleys 26, 23, 22, and 17 so that the motor 24: drives the shafts 15 and 20 and the cutting and milling tools 16 and 21 carried thereby. The free edge of the frame 18 is supported by a small vertical shaft 28, whose upper end is screwthreaded through a block 29 pivoted in said frame, and whose lower end is shouldered to extend loosely through and rest upon a lug 30 formed integrally on the plate 10. The upper end of the shaft 28 is provided with a hand-wheel 31 for revolving it, and thus the free edge of the frame 18 may be adjusted in height to have the milling tool 21 act properly upon the core 32 of the roll of paper 33. A tension spring 34: has its upper end attached to the free edge of the frame 18, and its lower end to a pin 35 on the plate 10, this spring acting yieldably in opposition to the shaft 28 to hold the free end of the frame 18 and the milling tool 21 downward.
The bed 7 is provided with a traveling carriage 36 which, in cross section, is in the form of an inverted L, the vertical portion 37 of this carriage extending down along the front face of the bed 7, while the horizontal portion 38 extends across the upper face of said bed. The rear edge of the horizontal portion 38 of the carriage 36 is provided with a depending sheet metal flange 39, which is secured to it by screws 40, and this flange holds the carriage from dropping I forwardly off of the bed 7. The lower face of the horizontal portion 38 of thecarriage 36 is provided with small rollers 41 which rollupon the upper face of the-bed 7 and the inner or rear face of the vertical portion 37 with rollers 42 which roll upon the front surface of said bed. The advance end of the carriage 36 is provided with an upwardly-projecting stationary arm 4:3, and the upper end of this arm has an integral cone 4L4 adapted'to have centering engagement with the core 32 of the roll of paper 33. The rear end of the carriage 36 is provided'with an upwardly-projecting arm 45 whose lower end is pivoted near the lower edge of the vertical portion 37 of said carriage, the upper end of this arm being provided with a cone 46 adapted to be swung into centering engagement with the core 32. A lever 47 is pivoted near the upper edge of the carriage 36, and adapted to force the cone 46 against the core 32.
In using the machine, the carriage is moved in the direction of the arrow 48 in Fig. 4, bringing the core 32 and roll of paper 33 first under the cutting tool 16 and thenunder the milling tool 21. The cutting tool 16, which may be a suitable circular saw, cuts the windings of paper down nearly to the core 32, but is kept out of contact with said core to avoid being dulled or injured. The milling tool 21 isof a character to withstand actual contact with the core 32, and is yieldably held down against said core by the spring.31,'said tool com-i pletely severing the few windings-of paper left by the tool 16.
By the use of the shaft 28 the milling tool 21 should be adjusted to such height that it will work through the paper 33 entirely to the surface of the core 32 in obedience to the spring 34:, and then drop downward a short distance, say one quarter of an inch, after said core has passed out from under it.
The foregoing being a full, clear, and exact description of the invention, what we claim and desire to secure by Letters Patent is 1. In a device of the class described, a carriage adapted to provide longitudinal movement of the core, a revolving tool adapted to cut through part of the windings of paper on the core, said tool being revoluble around a stationary axis, a second revoluble tool adapted to cut through the remaining windings of paper, said second tool revolving around an axis which is movable to and from said core, and means acting yieldably to force said second tool toward said core,
2. In a device of the class described, a carriage adapted to provide longitudinal movement of the core, an arbor mounted above the core, a cutting tool carried by said arbor and adapted to cut through part of the windings of paper on the core, a second arbor mounted above the core and carrying a tool adapted to act upon the remaining windings of paper, and means acting yieldably to force said second arbor toward said core.
3. In a device of the class described, a carriage adapted to provide longitudinal movement of the core, an arbor mounted in'stat-ionary bearings in position to extend above the core, a cutting tool carried by the arbor and adapted to cut through part of the windings of paper on the core, a second arbor mounted in vertically movable bearings in position to extend above the core, a tool carried by said second arbor and adapted to act upon the remaining windings of paper, and means acting yieldably to force the bearings of said second arbor toward said core.
