301mm M00. JOHNSTONE, or ROSELLE PARK, NEW, JERSEY, As'srcivon; 'r'o' cAMn oN MACHINE COMPANY, or BROOKLYN, NEW YORK, A donroan'rron or NEW YORK COMBINED SLITTING AND WINDING MACHINE Application filed August 29, 192 1. Serial No. 734,845.

This invention relates to surface winding machines, and 1s more part1cularly an improvement on the drlvlngmechanlsm shown in Patent No. 1,465,967 of August 28, 1923.

In that patent one of the surface winding drums carries an extension which forms the power shaft and from which other elements of the machine are driven. The main object and feature of this invention is to simplify this construction and to render the power unit entirely independent of the winding machine proper to the end that the power unit and the winding machine can be independently assembled and thereafter readily lined up and interconnected.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which: i

Fig. 1 is a general view in side elevation of a Winding and slitting machine embodying the invention, with parts broken away and in section for the sake of' clearness of illustration. 7

Fig. 2 is a plan view of one form of an intermediate means for transmitting motion from the power unit to the riding -roll.

Fig. 3 is a vertical longitudinal sectional view on the plane of line 3-,3 of Fig. 4.

Fig. 4: is a vertical transverse sectional view on the plane of line 4-4: of Fig. 1.

In the embodiment of the invention here disclosed 1 indicates a main frame of any suitable construction in which are mounted two winding drums 2 and 3 spaced apart and rotating in the same direction. These drums act against the wound material 1 on winding shaft 5. 6 is a top pressure or riding roll in a plane above the winding drums and intermediate the same. The winding shaft and riding roll are so mounted in the main frame as to rise as the diameter of the wound material increases in a manner well understood. Suitable slitting means are employed consisting of 'complementary cutting means of the score cut type. In the present instance a backing roll 7 is mounted in the main frame and associated with this backing roll is one or more score cutters 8.

The material 9, to be acted upon, is led into' 'the machine, in any suitable way and may pass over guide 10', thence between the slitting elements and thence over'one of the drums to the windingshaft; v

f On the end of each winding drum. is a spur gear lljand on the end ofthe "backing roll is likewise'aspur gear 12. These gears project beyond the main frame. Located adjacent the main frame at the side where the gears of the drums and slitting element project' is a'sub'sidiary frame' 13 which may be bolted to the main frame as at'14. This subsidiary frame carries the power unit.

Injthe'present instance this power unit con- 'sists' of a; power shaft 15 mountedin'bearing's'16 of the subsidiary frame". Motion is imparted to'th'e power shaft by any suitable means but preferably a'pulley 17 or' other power element and a clutch18 are used. .A brake pulley'19 is also associated with the shaft. The construction andmdd'e of'oper ation 'of'these parts. need not be described as they are fully" set .forth in Patent No."

1,465,967. Power shaft 15 islocatedin a plane'betweenthe two winding drums so that spur: gear 20 on'5saidshaft'15 will en,

gage and drive spur'gearsll, 11 011 the 'winding drums and will also engage and drivesnur'gear 12 on backing roll ,7-

' "It will now be understood thatthe parts of the" power unit may be assembled independently' oflthos'e comprising the winding machines, after which the power unit is lined up with the winding mechanism. This feature is ofgre'atadvantage in erecting the machine in the field, and also-when it is de-' sired to changefrom a'lefthand to a right hand machine or vice versa- It is customary to meansof'avertical shaft 21, mounted in the main fra-me, and sliding bevel gears' 2 2.

This}shaftfherefextendsin a plane. between the winding '--drums intermediate the ends of the drums. or main frame and the gears carried by said drums. On the lower end of shaft 21 is a bevel gear 23 which may be driven in any suitable way'such as by a bevel gear carried by spur gear 20. In this case it is preferred to mount a stud 24 in the main frame substantially in line with drive" the riding rollby' gear 20 and to mount thereon a bevel gear 25 that meshes with bevel gear 23. Bevel gear 25 is provided with a slot 26 and gear 20 carries a dog 27 engaging said slot. This intermediate mechanism or dog and slot connection is somewhat flexible so that slight inaccuracies in lining up the parts are compensated for. The bevel gear may be mount-v ed on the stud in any suitable way, but preferably a'retaining collar 28 and a thrust washer 29 areused so that end thrust in either direction may be taken up.

I claim:

1. A combined slitting and surface winding machine including: two surface winding r rums spaced apart and rotating in the same direction, slitting means including a rotating element and score-cut slitters, a gear on the end of each drum, a gear on the rotating element, a power shaft located below and intermediate the gears on the winding drums, a gear on the power shaft meshing with the gears on the winding drums'and on the rotating element and transmitting power to all of said gears, a riding roll above the winding drums and intermediate the same, a vertical shaft for driving the riding roll extending downwardly in a plane between the two winding drums and intermediate the ends of the drums and their gears, a bevel I gear at the lower end of said vertical shaft, and a bevel gear moving with the gear on the power shaft and engaging the bevel gear on the vertical shaft. y

2. A combined slitting and surface Winding machine including: a main frame, two surface winding drums spaced apart and rotating in the same direction carried by said main frame, slitting means including a rotating element and score-cut slitters also carried by saidmain frame, a gear on the end of each drum and projecting beyond said main frame, a gear on the rotating element also projecting beyond said main frame, a subsidiary frame adjacent the main frame at the point where the gears on the drums and rotating element project from the latter, and a power unit, carried by said subsidiary frame, including a power shaft located in a plane below and intermediate the two drums, and a gear on said power shaft meshing with the gears on the winding drums and on the rotating element and transmitting power toall of said gears.

Signed at New York city, in the borough of Brooklyn, county of Kings and State of New York, this 11 day of August, 1924.
