^ Specification of Letters Patent.
Pat'nted March 19,-;1907.
"Appamatiuradium,28,1906. sgrmtrtaosaas. l
ol' Lynn, eounty of Essexg'State ol Massaehusett s, have invented an Improvement in Iae 'per-l1 eeding Devices for W rapping-)l aclnnes,
'ol which the following description, 1n connection with the aeeompanving drawings, is a speeilioation, like characters on the drawings representing like parts.
In certain forms or types of wrapping-machines-suoli, lor instance, as shown in Letters Patent .No 472,202, dated April 5, 1592 the weh of" paper is drawn Irom a roll hy means ot devices which. act to leed it forward to a severing device which severs the wel).
and therehv produce wrappers of' suitahle size to he used lor-wra1k ping oranges and other things. The 'feeding device acts intermittingly and also rapidly to leed forward a predetermined length ot papcr'lor the wraper and when starting from a position oll rest will violently pull upon the weh ol paper and draw -it from the roll. ln practice l lind much dillieulty is experienced in controlling the weh of paper when drawn from the roll hv the feeding device, particularly when-operat ing the machine at. high speed.
This invention has` lor its ohjec-t to provide means independent ol the feeding device for drawing a pretletermined length of paper. l'rom the roll, corresponding to tlie length ol paper required for a wrapper] so that the feeding device may operate to perform.onl)` its regular .function of feeding forward the papery and also in connection with `said means to provide a hrake l'or the roll hy which the drawing otl' ol" the paper from the roll isvcontrolled in such manner as to enahle said means to suhsequcntly control the weh ol' paper which is drawn from the roll.
l `igure l shows a sullicient portion of a wrapping-ntachine to illustrate the paperleeding device emhod'uving this invention, the means l'or drawing the paper from the roll heing shown in l'ull lines in the position it will occupyl when a predetermined length of paper corresprmding to the` length of paper required l'or a wrapper has heen drawnv from th" roll and in dotted lines the position it will occupy when the predetermined length of paper which has heen `drawn from the roll has heen taken up by the feeding device.

'l`he imermiitinglv-operat-ed vfeeding device hv which predetermined lengths of paper are fed forward is herein shown as a pair ol' feeding-rolls -tl 42, journaled in suitahle hearings,the upper roll -ll hearing a loot hed gear 5.1 and the lower roll 42v hearing a. 'toothed gear .'32, lwhich engages said toothed gear 5l, wherehv one ofthe rollsis driven h v the other roll. A pinion 53, is loosely mounted on the shaft ol" thelower roll hearing one or more pawls 5S, which engages` ,the teeth of a ratchet-wheel 59,y which is secured tolsaid roll, and said pinion is engaged hv a rack-har 54, which is` supported in suitahle hearings and'which is loosely connected atv -one end to` an upright har 55', pivoted at its lower end to the main trame. 'At the lower end ot* the har a. lateral extension is provided, having a curved slot, and a har 57 is adjustahly connected at one end to said slotted extension 56, its opposite end heing connected to an eccentric on the main shat't lff. As the shaft revolves the. bar 5T is reciprocated and the rack-bar 54 correspondinglv moved longitudinally and the feeding-rolls operated to feed forwarda predetern'tined length of paper.
l desire it to he understood that my invention eomprehends the employment of anv other l'orm of feeding device in lieu of tlie lorm hereirrshown, which is adapted to be intermittinglv operated to feed forward preiletermined lengths oipaper.
f represents the paper-Carrying roll, the shaft of which isjournaled in suitable hearings in the frame. Asa means of drawing from the roll o?. predetermined lengths of lOO los.
paper a pull-'off device is provided which is y adapted toy operate and draw the paper from the lroll while the feeding device is at rest, and said pull-Gif device' is also adapted to 5, hold the web of paper thusdrawn off under constant tension while 'the feeding device 'operates lto feed forward a corresponding Q length of pa er, and the pull-oif device here" in shown il ustrates one practical embodi- Io ment of my invention. V The pull-off device herein shown consists of ya pair of arms 30, pivoted at 31 to the frame near the roll t?, 'and to the outer ends of said arms a paper engaging-roll, or it may bea cross-bar 32, is
supported, which is designed to extend transversely with respect to the web of paper. The pull-oif device is so larranged 4that :the roll borne by it engages the web of paper near the paper-carrying roll and thereby caused zo to rise and fall on its pivot. The pu1l-off device is made quite heavy and falls by gravity and is raised by the action of the eedingdevice drawing up the paper. The
web of paper from the roll i2 passes over the pull-oil' device and thence over an .idle A roll and thence -to the feeding device, and
the en'd thereof is engaged by said. feeding device.
While the feeding device is at rest and the v3o end of the web of paper is held by it, the ullofi' device falls by gravity into the ful -line position (shown in Fig. 1) and draws from the roll i2 a predetermined length of paper,.
and thereafter while the paper thus drawn 3 5 from the roll is held taut or undei` slight tension by the pull-off device the feeding device operates to feed forward a corresponding length of paper for a wrapper, the pull-ofil device being lifted meanwhi einto the dotted- 4o 'ine position shown in'Figpl. In order that the pull-off device may be lifted easily and quickly without material effort on the part of the feeding device, a counterbalancingweight 6() is provided for the pull-off device,
1. 5 said weight bein herein shown as arranged on an arm 6], W ich is pivoted at 62 to the frame near the pivot of the pull-off device,
.Y and gear-teeth 63 are formed on -or attached to the pivoted end of the arm which engage 5o. similargear-teeth 64, formed on or attached to the 'pivoted end. of the pull-olf device. The counterbalarming-weight y is thus connected with the pull-oil' device in such manner that as the pull-off device falls by gravity v5 5 the weight will. be lifted, and vice versa.
Hence by roviding the weight the pull-olf device will equite easily lifted.
It will be seen that the pull-olf device and the feeding device operate alternately, the 6o former acting to draw a predetermined length ol" paper from the roll while the latter 'is at rest andl then the latter operating to feed forward a corresponding length of paper while the former rises and holds the web of the brake-band. j the pressure device on the brake-band is up the paper to the feeding-device'as rei quired.
At one end of the paper-carrying roll i2 a brake wheel or drum 28 is secured, and a block 27, which is pivoted to one of the arms 30, bein I#placed in a hole dpassing trans'- versely t rough said arm, 'an
said bar 29 is as at 36,l and the other end is free to slide longitudinally in said pivoted block, land a spring 37 encircles said. bar, which bears at one end against the arm 30 `and at th@J other end against a collar 26, which is fixed to the arm, the action of said spring being`to thrust the sliding bar in a .direction away from the arm, and the free or outer endvof the brake-band 35 is attached tothe extremity of said sliding bar.
As 4the pull-off device is raised and lowered the brake-band is graduallyl unwound from i' and wound upon the brake wheel or drum, 'and by thusdecreasingandincreasing its area of contact with said drum saidbrake becomes accumulative, and, furthermore, when the pull-9H device lin falling has wound the brake-band upon the drum it continues to fall 'and to compress the spring on the .Slidingban `and thereby apply a graduallyf A increaslng pressure upon the free end of the ,brake-band. To prevent rotation of` the paper-carrying roll when the pull-off' device is raised to its most elevated position and while it is still held up by the web of paper, and also while the paper is being 'drawn up by the feeding device, a pressure device 1s provided which is applied tot the brake-band, which holds a portion thereof in continuous engagement with the brake wheel or drum.
The pressure device herein shown consists of awide flat spring 25, attached at' one end to' the frame, its opposite end being free, and said spring is 'so held as to exert a con'- stant pressure upon the portion of the brakeband which it engages. An adjusting screw 24 is provided which operates upon said spring to increase or diminish the pressure which it is desired it shall exert upon The pressure exerted byy suflicient to hold the roll 'i2 from rotating ex-l cept when thepull-oll' device falls by gravity.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, ism- 1. In a wrapping-machine, the combination of a 'feeding device, means for operating 65 paper taut or under sliglu tension, giving l it to feed forward a predetermined length of IOO erases ted by gravity to mined length of is at rest and off device which is opera i draw from the roll a predeter paper while the feeding device which is lifted by the actie devicewhile the latter operates to feed the paper, Ymeans for restraining the gravitating. movement of the pull-off v"d'evice,and a ift-A vice, anda yielding pressure device bearing ingeweight connected with saidpuli-o ydeupon said brake-band to hold la ortion there vice which assists the feeding device in rais` of `incorretant engagement wit said brake-l ing said pull-off device-,' substantially as de-` wheel, substantially as I scribed.
