This invention relates to certain improvements'in winding machines,and more articularly to that type in which paper rom a paper making machine, a reel or othersource is slitted into'sections o'r trimmedand rewound;

i The present invention is adapted for vuse in that type of winding machine which s pro-,.

These rack bars to insure the simultaneous movement of both ends f the pressure roller and the resultant uniform application of pressure along thethese rack bars extend a material distance above the machine as the roll of material becomes larger in diameter, requiring thereby a corresponding increasein' space to accommodate for the extension of these-racks. places where the available vertical s'pace'is limited such extensions are a decided disadvantage; I

The gears which mesh withathe rack bam are positioned towardsthe top Of'the-machine andconnected together to rotate simultaneously with said rack bars. The result is that as soon as the diameterof the roll begins to increase, the end of the rack bar roll, and a driven pressure roller pressmg below the top of the machine.

The present invention accordingly provides means whereby the movable rack bars 'of a windmg machine are more efiectively confined within the body of the machine as the roll of material being wound increases in diameter. Y

In the present invention, the. bottom end of eachrack bar is disposed close to the base of the machine when the win'din shaft ism in its lowermost position. The dength of these rack; bars are made but a little longer than theextreme diameter of the paper roll so that-1n this lowermost position ,the top ends of the bar will be a substantial distance The gears {116511111 with these rack bars are positioned Just be ow the tops of the rack bars when in this lowermost position, so that these rack .bars will have traveled through nearly'their entire ran e of movement be ore they begin to extend eyond the generalcontour of the machlne. It is preferred to provide a rack with the teeth facing inwardlyvtowards the main body of the machine and the gear intermeshing therewith correspondingly posi tioned in order to effect a more compact machine. Through the instrumentality of these will be confined in a much smaller space during extreme limits of operation.

The invention also consists in certain new 7 and important features of constructibnand combinations .of-parts hereinafter setv forth and-claimed.

' Although the novel features'which are be; lieved to be characteristic of this invention will be particularly pointed out in the ap pended claims,- the invention itself, as to its objects and advantages, the mpde of its op.- eration and the manner of its organization maybe better understood by referring to the following description taken in connection claims parts will be identified by specific i with the accompanyingdrawings forming a part thereof, in which Fig. 1 is a front elevation of the machine.

Fig. 2 is a section taken on line 2--2 of Like reference characters denote like parts in the several figures of the drawings.

In the following' description and in the names for convenience, but they are intended to beas generic in their application. to similar parts 'as the art will permit.

In accordance with a specific embodiment I of the present invention exemplified inthe accompanying drawings, a pair ofend frames 10 areprovided, supported by base-members 11 and 12 and suitabl braced together by a pluralit of structura elements. The frame pieces 10 serve to support the operating-elements of the machine such as the winding shaft the pressure roller, supporting drums and the like.

The course ofizhe paper to be slitted and wound isindicated by the dot and dash line' in Fig. 2, and is shown as passing in contact with the idler rollers 13,14 and 15, into the field of action of, cutters'16 and 17, around the guide roller 18, and in contact with a front supporting or windin drum and winding drum 20-.co-operates with a similar drum 22, and both'conjointly serve to support a roll of paper 23 as well as rotate this 'roll about the windingsha'ft 21, I j

This intermediate gear 31 also serves to drive a gear 32 mounted on the-shaft 33 of the cutters 16 so that said cutters and the drums 20 and 22 are driven at, the proper relative speeds, and

Co-operating with the surface of the 11'011 of material 23 as it is being wound, is a pres- ;sure or riding roller 40 mounted on a shaft 41, the ends of which are journaled in vertically movable bearing blocks 42. This pressure roller 40 is positively driven, and for that purpose the shaft 41 thereof has mounted at one-end a bevel gear 43'which meshes with a slidable bevel gear 44 keyed onto. a

vertical shaft 45. The lower end of-this shaft 45 carries a bevel gear 46 which meshes with a bevel ear 47. carried on the shaft which carries t e intermediate gear 31. By this means, the pressure roller'40 is free to slide vertically as the diameter of the paper roll 23'increases and is continuously rotated in conjunction with this vertical movement.

The gear 47 has a friction drive, and the" friction is adjustable, thus the'pressure roll can bedrlven faster than the paper and slip on the surface of the roll, or the friction can slip and theroll willrun at the same speed as the paper but exert a pull on the paper.

All of this construction hereinbefore deshribed is oldan'dwell-known in the art andforms no part of the resent invention. The important feature 0 7 this inventio resides 'mamly' in the provision of improved means for holding the pressure roller 40 absolutely parallel'with the winding drums 20 and 22, st that the constituent elements of this means are more closely confined within the body of the machine when in extreme operating positions- In accordance with this improved means, the bearing blocks 42 ma have extending therebetween a bar 50 whic carries brackets 51 at each end thereof. These brackets 51 are fixed to a pair.of rack bars 52 having theteeth thereof turned rearwardly towards the body of the machine. These rack bars are mounted for slidable' movement along the guide bars 53, and are adaptposition.

The rack bars 52 mesh wlith large gears 54 which in turnmesh with small pinions 55 lrigislly connected together to a common shaft 56.' This shaft 5 6 is provided with a-brakearrangement 57 which can be adjusted toefl'ect selective resistanceto the rotationv of the gear '54 and consequently to the vertical pressure of the roller 40 on the paperroll 23 can be accordingly regulated. Thegears 54 are preferably ,of comparatively large diameter and are preferably positioned ap- .ed to extend in close proximityrto the baseof the machine when in the lowest extreme movement of the roller,40. In this way, the

may be more effectively, easily and accurately adjusted .to give the desired resistance to the upward movement of the pressure roll.

ment end to its associated rack bar 52. This will cause a simultaneous movement of the bars 52 endwise, and will thereby obviate the V possibility of the pressure roller being lifted to a lgigher level at oneend of the roll surface than at the other.

During the initial operation of winding the paper around the winding shaft 21, the

lower end of the rack bars 52 will be disposed near the base of the machine proximate the position A indicated in Fig. 2. It should be noted that the length of this rack bar 52 is but slightly longer than the maximum diameter of the paper roll 23. The top of the bars during the initial winding operation will be disposed proximately in the position B. The gears 54 will then be disposed in intermeshed relationship with the rack bars 52 slightly below this position B. When the roll 23 has attained its maximum diameter, the bottom ends of the rack bars 52 will be slightly below the rack meshed portions of the gears 54: while the top ends will be proximately in the indicated position C.-

It should be noted that this improved organization permits the gears 54 to be positionedat a substantial distance below the top of the machine, and that the to end of the rack bar will be at a correspon ingly lower position when the winding shaft 21 disposed in its extremel'owermost position. By this means, the top end of the rack bars 52 will have traveled a substantial distance within the body of the machine in response to the increase in diameter of the roll 23 'before this end begins to extend beyond the general contour of the machine thereby confimng the elements of the machinemore closely to the body of the machine during extreme operating positions.

For facilitatingthe raising of the pressure roller mechanism when the friction brake device 57 is released there is provided a pair of counter-balancing weights 6O vertically slidable on't-he rear of the end frame 10 and each connected to its corresponding bearing blocks 42 by a chain- 61/ extending over a pair of sprocket Wheels 62 and 63. 'For positively raising or lowering the pressure roller mechanisin there is provided a crank hand wheel or other suitable means (not shown) operatively connected to one of said sprocket wheels 62 and 63, and adapted to effect said positive movement to said mechanism.

While certain novel features of the invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitu- 7 tions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spiritof t e invention.
