This invention relates to a paper winding apparatus for winding reels, of paper or for .rewinding paper into different size rolls.

In paper winding apparatus of the type to which my invention belongs one of the difficulties-lies in the removal of the reels of wound paper from the machine. In present day paper makin apparatus, the reels of paper as made on t e modern paper machines are often as wide as 20 ft. The reels, therefore, are exceedingly heavy and dificult to handle except by mechanical means. So far, these'mechanical means generally take the form of over-head tackle for engaging the 5 ends of the winding shaft and lifting the reel bodily from one position to another. Bymeason of the great weight of the wound reels of paper, .the winding shafts must necessarily be made extra heavy to provide against bend- 24 ing when the reelis lifted from its ends.

The present invention has for its object to provide mechanical means for'discharging' the wound reel of pape fi'om the winding apparatus while at the same time supporting as the reel throughout its length, whereby no undue strain 1s placed upon the winding I shaft and accordingly, a lighter shaft, or even one of aluminum, may be employed.

A further object of this invention is to proan vide simple mechanical means for facilitating the discharge of reels of paper from paper winding apparatus.

Other and further important objects of this invention will be apparent from the dieas closures of the following description and the accompanying drawings:

On the drawings: Figure 1 is a'broken side elevational view of a paper winding apparatus embodying the to principles of my invention; 1 Figure 2 is a top plan view of the same with parts removed; 1

Figure 3 is an enlarged sectional view taken substantially online III-III of Figto with parts omitted, v

The reference numeral 1 indicates as a whole a supporting frame of a paper winding apparatus comprising a base 2 and a pair of upright side members 3. Asds customary in this type of winding apparatus, a pair of 5 under drums at and 5 serve to wind the paper upon a winding shaft 6 cooperatively associated with said under drums. The present invention is directed more particularly to the arrangement and mounting of said under an drums/i and 5 to permit said drums to be tilted or rocked to thereby cause a wound roll of paper on said shaft 6 to be discharged over the surface of one of the under drums on to a receiving platform. y as The front journals 7 and 8 of the drums f and 5, respectively, are rotatably mounted in split bearing brackets 9 and 10, respectively, which in turn are bolted or otherwise secured to a cradle 11. Said cradle 11, in turn, is to mounted for rocking movement upon a cradle supporting frame 12 formed upon the front end of the base 2. At the rear, the under drums 4 and 5 are provided with extended journals 13 and 14,- respectively, (Figure 2) 76 supported in brackets 15 and 16,respectively, secured to a cradle 17, similar in construction to the front cradle 11. The front cradle 11, therefore, will be described only, it being understood that the two cradles are identical. so As best shown in Figures 3 and 5 said front cradlell'is provided with lower, arcuateshaped spaced-flanges. 18 and 19 ada ted to extend between spaced guides 20 an 21 formed on said cradle supporting frame 12. The lower arcuate shaped surfaces of said flanges 18 and 19 rest upon similar shaped bearing surfaces '22 and 23 formed on the cradle suppdrting frame 12. The centers of curvature of said arcuate surfaces all he in an imaginary axis in the plane of the axes of said drums 4 and 5.

An arcuate shaped tongue 24 positioned between said depending flanges 18 and 19 andextending therebeyond is provided at its rear end with rack teeth 25 adapted to mesh with as a pinion gear 26. Said pinion gear 26 and, a second pinion gear 27 for the rear cradle 17 are both mounted upon a shaft 28 journaled in the supporting base 2. Said driven shaft 28 is provided with a rearward extension 29 on we which is mounted a clutch member 30, cooperatively associated with a second clutch member 31 mounted upon a stub shaft 32. The stub shaft 32 is driven through a worm and gear arrangement enclosed within a housing 33, from a counter shaft 34, which in turn is driven from a reversible motor 35 through a train of gears 36 and 37, and clutch discs 38 and 39. The gear 37 is loosely mounted upon the counter shaft 34: and the clutch disc 39 secured to the hub of said gear 37. The second clutch disc 38 is rotatable with the shaft 34 but movable longitudinally thereof and adapted to be pressed into engagement with the disc 39 by means of a heavy coiled spring 40, positioned between the disc 38 and -a nut and washer 41 on the end of said counter shaft 34. This provision of the friction discs 38 and 39 allows sufiicient slippage in the drive connection between the motor and the rack gears on the cradies 11 and 17 to prevent injury to the motor when further movement of the said cradles is impossible.

The main drive for the under drums i and 5 comprises a. shaft 452 (Figure 2) adapted to be directly driven through a clutch connection 43 or to be driven by means of abelt through a conical pulley i t mounted upon said shaft. ings 45 and 46 and carries gears d'i' and 48 adapted to mesh with gears 49 and 50, respectively. upon the extended rear ends 13 and 14 of the drums 4 and 5. In order that the gears 49 and 50 may move over the gears 47 and 48 during tilting of the drums l audit it is obvious that the axis ofthe shaft 42 must be coincident with the imaginary axis of curvature referred to above.

The winding shaft 6 is adapted to be supported at-its ends in split bearing clamps 51 mounted upon the lower ends of vertically adjustable rods 52. Said rods 52 are adapted to slide in guideways 53 formed in the upright side frame members 3 and are connected in the usual standard manner by means of cords or cables 54 trained over pulleys 55 to counterweights 56. A hand wheel 5'? mounted upon a shaft 58 serves to raise and lower the windin; shaft 6. c

When the winding machine is in operation a web of paper 59 (Figure 3] is threaded under the drum 4 and its end wrapped about the winding shaft 6. The under drums 4 and 5 are then set in motion and the web of paper wound upon a shaft 6 by surface contact with the revolving drums. A reel 60 of wound paper is thus formed which gradually grows in size until a full sized reel 61 (Figure 4) has been produced.

To'remove the 'reel 61 from the winding drums, the bearing clamps 51 are disengaged from the ends of the winding shaft 6 and the motor 35 started up to eii'ect a partial rotation of the cradle members 11 and 17 in their respective supporting frames. The under The shaft 42 is mounted in bear-v drums 4 and 5 are thus tilted into the position shown, with the drum 4 in elevated position and the drum 5in depressed position.

The drums i and 5 are brought back to normal position by reversing the direction of the motor Stops 64 formed upon the ends of the cradles i1 and 17 are adapted to engage lugs 65 formed upon the supporting frames 12 to prevent movement of the cradles beyond normal position.

It will be understood that the winding apparatus of my invention is equally adaptable to winding material other than paper. The important features of my invention are the provision of means for rocking or tiltin the under drums about a common longituinal axis to facilitate the discharge of heavy reels of wound web material. Because of the fact that the heavy reelsdo not have to be lifted from their ends much lighter and cheaper winding shafts'may be employed than heretofore without danger of'their buckling.

My invention also saves a considerable amount of manual labor over the present forms of winding apparatus and eliminates the possibility of injury to the reels of paper through being dropped. r

I am aware. that manychanges may be made and numerous details of construction may be varied through awide range without departingfrom the principles of this invention, and I. therefore, do not purpose lim iting the patent granted hereon otherwise than necessitated by the prior art.
