o Be a known um I, McoLrNTooi; Yonne,

of Frederick-,in theI county of, Frederick andj State of Maryland, have inventedeertain new and useful: Improvements in Al V, [a I 1ufacturin g Paper Tubes, of which the following is a speciioationz-v i y The object of my invention, mainly,4 is to :manufacture tubes from a strip or strips ofpavper by one continuous connected operation 5 I and, further, to sever the tube into blanks of k lengths vsuitable ,for` boxes by automatically-A -operating mechanism.A

' My invention .consists in ay novel organiza-` tion of mechanism, and in certain constructions .ofparts and 'combinations of devices, v which will hereinafter specifically be designated.

In the accompanying drawings I have shown all my improvements as embodied in the best Way now known to me. Obviously, however, some ofthe parts may be used without the t others, and inmachinesjdiifering somewhat from the one .therein shown and herein described.

` The 'details of construction 'of portions of vthe mechanism for carryingout my, invention may be varied inv some .respects` without de-l parting from the spirit of my vinvention,"which variation'swould be readily suggested to skillful mechanics, or thoseskilled in the artto ,which my invention pertains, simply by 11e-ending*this specification and examining g vthe drawinin which- Figure 1 is a plan ervtop view with the .camdrum in the position assumed just previousto n the time of retractingthe mandrelfs'ectionrst withdrawn; Fig. 2, a side elevation withythe cam-drum inthe same position.;l Fig 3, an elevation of the delivery end of the machine,or

At theirlower ends these springs arehori -zontallylbent or forked 4fand coiled, as' clearly shown in the drawings.

series oi' cams On the forward movement ofi fthe mandrel, a Jpartialrotat'ion is imparted. to

it (all the sections caused to turn together reason of their abutting edges) by means of la pin orroller-stud, rn, secured to the-end lof ltheg I core Il., and vengaging with La spiral slot, n, ini

a liollowshaft or sleeve, N, rigidly connected with `or forming part lof theshaft l, before-mentioned. This tubular -shaftN is heldstationary ,1

during the advance lof the mandrel, and pref vented from rotating in the Wrong direction,

Aby a ratchet-wheel, N, and pawl N?, piv-.

oted at nz-to the frame or base-plate in suitable manner. This pawl is kept in contact with the ratchet by its weight alone; but rai V-spring may be employed, if desired. To .pre-f;

vent accidental rotation of. the mandrel in;I

vthewrong direction, and guard against .its re- I volving on the backward movement, a ratchetengaged by a broad-faced'pawl, O, which. admits ofthe reciprocation of the mandrel without clearing the wheel from the pawl,'fas well asallows the mandrel freely to be revolved in the proper direction. The same pivot, n2. as that-by which the pawl Nzis hinged to the frame serves also to fsupportvthis pawl 10'.'

It will be seen that on 'the advance of the mandrel thesleeve Nisheld fromrotating by its pawl, and thek mandrel forced to revolve,

while on the return stroke the Asleeve revolves, -and the mandrel is-k prevented from turning. By increasing or lessening the length of' the Aslot nl, and giving a lon-ger or :shorter stroke 'to the mandrel, or by givinga greater or lessij pitch to this slot, the :amount of turn -:given to the mandrel may be increased or diminished at will, as is well understood. :The pivoted. iframes L Ll L2 -carry rollers p p1 pyrespectively, which project into `the tracks or kgrooves I P P1 P2 ofthe cam-drum .on the driving-shaft '0.' f

A corresponding portion,Q Q1 Q2., l.of each'-l groove is formed aliketo 4operate on the roll- I ers of the respective liframes, toV advance the When thus Aad-v vanced, the straight parts R Rl R2Y of the grooves come in contact with the rollers simultaneously, and hold the mandrelxstation#l ary in its advanced position for Aa `short while. At this moment a cutter severs from the tube that portion of its length projecting beyond the mandrel, as will presently be explained. Next, the inclined portion S2 of the track P2 acts on the roller p, vibrates the frame L1 backward, and retraots the section h1,- next, the corresponding portion S1 of the track P1 comes in contact with the roller of the frame like portion, S, of the cam l? runs on the roller p, and moves'back the section li, thus completing the. backward reei-procation of the man- Fdrel, vand' leaving vit ready to beV again Iadvan'oed,gas described, to repeatitsreciprocation.

Thesblanks .fare severed from the tube by a cutter, T, (shown as v'composed of a `circular saw or toothed disk,) which is thrown intoop- 4'eration at the proper time-thatis, when the mandrel is advanced Lso asV to out closeito vits end, land prevent injuryto the tube. When the cut-away or recessed Apart u of a cam,.U,.on the `shaftfG ycomes in contact .with raroller, T, .on the saw-frame T2, .the weightk ofthe frame causes -it` to :descend vand. bring the .saw to the tube advanced from the mandrel.. The. frame is held felevated while .the roller moves `in contact with they regulary lsurface of the cam.

-Thejcutter is rapidly rotated by a belt passing -around a pulley, V, onl the sawarborfand around `a corresponding pulley, V', on the shaftW, 'on whichthe cutter-frame rocks. A pulley, W, on this shaft is driven by a k'belt 'passing from the driving-shaft, or driven in any Yother suitable way. v

- The operation of my machine .will readily be seen .from the foregoing description, itbeing understood .that the main `shaft is revolved .by power applied in` any -of the usual-Ways. As described, by my improvements a tube is automatically formed and severed into lengths suitable for box-blanks from two strips of paper passing tothe mandrel Vat an .acute .angle therewith, and drawn forward (and woundv thereon in such manner that the ledges of each .strip abut but do not overlap, the top .strip being caused to `adhere throughout its entire -un der `surface to the inner stri-p,and thus form Y tubes of a `double thickness of paper, with smooth, yclose joints. It is obvious, however,

that by changing the .location of the paperfcarrying, .frame relatively to that. of the many'drel the strips might be caused to lap kat their edges, and this lapbe increased .to `anydesiredl extent, simply by adjusting. the Jpaper-carrying-frame or roller to :a .positionfwhioh will cause the -paper to be presentedto the man- -rdrel more nearly :at al right angle therewith. It is valso v.manifest thatra tube may be made up fof-a single strip of paper by applying the paste .to-the under. side of the overlapping frontedge of the strip. Obviously'the pastetrough may be lessened in length to'so apply thepa'ste. y e l' l'alvhree lor even` more stripsmay be wound upon the mandrel together, `and. pastefapp'lied tothe. under .siu'face of all exceptl the yinner one, to make verystron g tubes; or `a seriesof strips, each pasted. upon itself at its overlap. vping edges, with or without uniting layers of paste between the different tubes, may be made. f

The angle formed by the paper-carrying or roller frameand the mandrel may readily be Vchanged by means of a slot and set-screw, as shown in dotted lines in Fig. 1, the pin or .screw w (shown` inl full `lines in" is'aidfigure)v serving as `a center frame.
