To al! 'whom 'it may concern:

Be it known that I, Emilien ZEBLEY Tinon, u. citizen of the United States, residing lut 40, 4l, and Percival street, Goswell Rond, in the city of London, England, engineer, have invented certain new and useful Improvements in Machines for Makin Conicfil Paper Tubes, of which the following is a specification.

This invent-ion relates to machinery for ille manufacture of conical tubes of p a, er, or the like, the object being lo provi c ii machine by means of-w'hic:h the operations of pasting u blank which. has been pre-q viously cut to ilie necessary form, and of' subsequently rolling such blank up into shape muy be expeditiouslynnd economically effected.

The machine luis been specially designed for use in the iiiuiiuifacture of paper vessels of that class which :ire used for the delivery ci' mill: cr cream to customers, and' which ure neen-illy of `conical form, ts'pering slightly 'from the top inward, und coinprise n paper body into which :i bottom piece, also of paper, is fitted.

l will proceed to describe-inydniproved machine in connection with the accompanying.,lr drawings', in'which:-

' AFigure 1 is u plan View of the machine, with parts in sect-ion, and other part-s removed to enable the operation to bemore clearly seen.' Fig. 2 a longitudinal section through such machine, Figli a detail View" of the stripper operating' mechanism, and platen und means for operating saine.

In carrying out my invent-ion I employ I u inuin driving shufifl, on whichfast and which by mea'iis of 3 are mounted, and

loose pulleys .2 and bevel pinion 4 and bevel wheel '5 communicates motion to a vertical shaft 6, on the lower'end o'kvvfhich is ai lpinion 7 engaging with a `large geez' wheel 8. l rotary n'ioveinent imparted to it, 'which movement is utilized to effect the operation of the various setsof described.

In the arrangement illiistrated three sets of pasting apparatus and 'three setsof rolling apparatus are combined and operated vin such l1 manner as to secure the eatest possible output of the machine. Igtrwill, how

radial slots 20 formed in such spokes. side guides-17 muy also-pass through redini The hitter 'thus-Lilus u continuous.

a'piimtifs' hereinafter com le'ted' vessels are -thic ss lof the paper used in 'their meow that. the bla-nhs he of ever, be understood that by disconnecting one or more sets of each class of appui-eins the output muy be modified to suit the quirements,' and further, that. histo-.id oi? there being only three sets of euch elf-iss there may be four, or more.

The blanks to be operated on :re placed on tables or p laten's 9 to .which rotary movement is imparted by ineens of the gear wheel 8, which is mounted nea-r the lower end of c. central sleeve or column l0, surroundiico :i screw spindle 11, on which works a nut 1Q., which is prevented from turning relatively lo column 10 by 'forming it with Wings 13, Working in slots 14, formed in column l0. The boss 15 of platens 9 is secured to u-: outer ends of wings 13 by means of bolts lo, and such platens y:ire therefore supported by nut I2, while in addition to the rotary move ment imported to the pletens'by such column such lowered by the means and hereinafter described.-

The blanks :ire reta-ined in' their proper positions on the platens by means of side guides 17 and hack supports or fences The side guides 17 ina-y conveniently be carried by the spokes of gear Wheel 8, and fo." the purpose of enabling same to' be adjusted to= suit different sized blanks are prefer ably secured by bolts 19 lpassing; through The for the purpose slots21. in the platens 9, and as sliown clearly in F ig. 2 will hold the (blanks 22 securely in .position against sidewise movement.

As there will'beno tendency for the blanks to move end'wise, except in the. direction oprotary, movemenl; of the Intens, itis only necessary to rovide the ack suppmjtsA or.; fences i8, Whig: avre'preferably bolted to side extensions of the spokesv of gear wheel 8,-end extend upward to o proximately lthe sume height us the up, .inostblank V oftheseries .on platen 9, t ieir upper-edges'being inclined at :in inclination .corresponding to that of the platen surface,

plotens are capable of being raised und It should'bestated that' as tliesidesof the l usually f double thrsuoli lengfh'as to twice encircle the! :ii-Emir; i

In the operation o'l'K the machine the blanks first arrive at thc pasting.; mechanism, which is dis )used above them and :.xrranged to be out ofI contact with the upper one during,r thc first part of the travel, and is then lowered so ato, apply the paste to the second half of the upper blank as the latter passes thereunder.

. The pasting aplnrratus comprises a pair 1.0;01. conical rollers 23, 24, the former of which ils 4mounted at a slightly lower level than the latter andconsitulcs the pastor proper, the

roller 2li merely comet-ing with it to insure the supply of pasto. A reservoir 253 of paste.,

thelower open end of' which is so formed as to be closed by the rollers, is mounted fabove the latter. Such, rollers 23,124 are continuously rotated. through the gear wheel 8, by means of a pinion 26 on the lower end @of a vertical spindle 27 passing through a' standard At. the upper end of such 'iwindard the spindle 27 is enlarged and orn'ied wit-li a tongue .29 normally engaging .groove in the enlarged lower end oi a shaftV 0, in line with and` practically 'forming a continuation of shaft 2T, the motion of the platter being always cmninunicated to shaft 30 when the tongue 29 is in engagement with thegroove. 0n shaft 30 is a bevel gear 31.

0f rolier 23. wliich is thus rotated, and by its Contact with roller 24. also rotates the latter, so that the two by their conjoint action will feed the paste.

The outer extremity of the pasting mechanism is sivlpported by a. horizontal shaft carried in bearings 3i. at. the upper end of the standard 28 abode referred to, while atv its inner'extremity 4it is provided with a foot piece carrying a roller 36, working .1in conjunction with a cam 37, mounted on fthe central screw 1l. The upper edge of this cam, on which` roller 36 runs, is so "formed that as the central screw 11 rotates lfthe pasting mechanism willv be alternately raised and lowered, these movements taking 'place atsuch times thatuthc pilcsof blanks .22 will have passed approximately half way 50, tinderthe. pasting roller 23 before the latter s llowered into Contact therewith, and such '.roller 23 will be again raised before the next pile of blanks Q2 arrives beneath same. 4The' footiiece 351s also formed with a surfa'ce 38 a apted to normally reshwlien such' .'rfppt piece isili its lowered position in rela- Mion to cam ,37, on the roughened upper surface 4of a friction 'disk '39 mounted rigidlypn-tlie central screw 1l, this contact be- 'nig tilincd to control the upward lfeed of hV lo'fiblauks, 'so as toV always retain p pter one. at. approximately the. same whooperetionof this arrangement is en bvfoobpiece 35 presses heavily on disk' es forinstance when a engaging with a bevel gear 32 on'thc spindlethefblenks have been removed from the piles so that the grealer part of the weight of the pasting mechanism is supported by such dish' 39, this pressure will have a retarding,Y action on thc rotation of the screw, causing it to worlc slightly through its nut 12. and as (he lat-ter cannot turn owing to its wings 18 engaging the slots 14 in central column l0, Such nut will be correspondingly raised, carrying with it the platens 9, on which the piles ot' blanks are mounted, so bringing the upper blanks to their proper height in relation tothe pasting mechanism.

The foot piece carries the bearings for the inner ends of the pasting and .feed rollers 23 and 24, and is supported from the horizontal shaft 33 by means of rods 40, the outer ends of which are carried by posts 41 provided with bearings 42, mounted on shaft- 33. The bearings for the outer ends of the rollers 23 sind 24 are supported from these rods by means of a cross bar 43. Such rods 40 also serve to support the paste reservoirv 25, which may be secured thereto by means of thnn'ibscrcws 43 as shown in Fig. l.

A. belt. or cord pulley 44 (Figs. 2 and 4) may be mounted. on the upper end ot' shaft 30 and be connected by a bell or cord 45 with a corresponding pulley lo' on thc upper end of the central screw 1l, such bell or cord being arranged to run loosely so that it does not transmit motion during thc ordinaryT running of the machine. When, however, the platen 9 has reached its highest position and itis desired to lower it, this may be effected by slightly lifting the inner rnd of the pasting mechanism, sufficiently to tighten the belt or cord 45 without disengaging the tongue 29 on shaft 27 from the groove in the lower end of shaft 30. when the motion of the la. .ter will be transmitted to the central screw ll, and as this motion will be in the opposite direction to that im parted to it in the general operation of thc machine the nut l2 will with the platone 9 carried thereby be returned io their lowermost position ready for a resh charge of blanks.,

It will be seen tht with the arrangement above described, as all the parts of the past ing mechanism are mounted pivotally in .relation to shaft 83, such entire mechanism cainif desired, bc turned right over on such shaft as a. pivot, enabling easy access to be had to partsA not otherwise readily accessible, and also permitting of the pasting mechanism being thoroughly cleaned when necessary by pouring hot water over saine, or otherwise. A .bracket 4?, shown broken oil in 2) may conveniently be secured to the outer side'ofstandard 28 and be provided .at its outer 'end with a part with which the foot piece 35niay come in contactwhen' the pasting mechanism is thus turned over. the past-ing of theblan'ks has been ill of the blank being taken up by 'iti top blank from each pile undroll it .u a to the. desired form, For this purpose-it is preferred to employ en arrangement such es that illustrated, in which each set of roll ing mechanism comprises: u. lurality (three as chown for instance) of t e ectual appliances for effecting the rolling operation, these seperate appliances operating one'et a time and 'boing their brought to an inoperative position in which the attendant may? remove fthe .rolled blank.

Erichrolling tippe-rat us comprises :eeroller or inelidrel/S .of conical form correspond-y ing to "that, desired in the finished article, end' to which ,al continuous rotary motion is impxrtedjby means of bevel gear wheels 49 und' 50 .mounted 'respectively on the shafts A6, 66, 56 and on horizontally arranged spindles'bl carried in a head 52. To cause the conicul rollers 48 to grip the blunlts when they come in contact therewith suction may be employed, the rollers 48 in this cese being hnelly perforated along the whole length of that-portion of thelr circumference which The spindles 51 contactswitli 'the forward edge of the blank.,

on'which the rollers are mounted are preferably hollow, and the bore is, when lthe roller is in its operative posi.- tion., connected up to that of a hollow vertic-,1l spindle 5'3, the upper end of which communicates through ppeM with a. fitting 55 through which the suction is produced by any suitable means. The forw'ard edge the means described, the continued movement. of the platen and the rotary movement'. of, the conicul roller' 48 on its to oli up the Whole length of such blank ont-he roller, bringing the pasted portion the outer surface of the portion vfind causing it to vadhere into' contact wit-h unpested thereto.

Whenv the blank has been completely rolled up it is-'ready for delivery from the machine, und for the purpose vof assisting its removal,- Which may a strip er 56 is employed. sume beingr mount on the hollow spindle 5l, ot' each of thefrollingfappliances. The meunst'or operating such vstripper is chou-'n more particularly in Fig. 3 and comprise :rbent lever 57 pivoted et 58 to the standard in which the shafts 6,66, operate. At its outenfree end lever 57 carries u roller 59, which works against n cam 60 on the under side of gear wheel 8., while its other end engages between collars on e vertical shaft 61 the up Aperend of which is caused, when cam 60 actuates lever l5'2", to come into contact with the tuilendof the .lever 62 for operating the stripper b, turning the lever 62 on its ,spindle 5l will cooperate be effected by hand',

'which as shown projects slightly beyond the Edge of' roller 48, such' rolled up blanlt will be forced slightly outward, just sulliciently to free ity from the roller, and it can then bc removed by hand. Such action ot' the stripper :md removal of the rolled blank are preferably, as in the arrangement shown, dieferrcrluntil the roller 48, which has been in use, has been turned to :1n inolwruti-Ve position, and which may be ell'ccted in the following manncr:-The head 52 carrying thc spindle 5l on which the rollers 48 are mounted is arranged so as to be capable of turning in relation to the central spindles 6, 66 by which the rotary motion is communicated to the rollers, such head being carried by a, sleeve- 63 surrounding shafts 6, 66 und having keyed thereto at its lower end n stur Wheel to which an intermittentmotion may be imparted by any suitable means, as for instance by causing such stur Wheel to engage rolle-rs 67 mounted on gear wheel S. lt will bo seen that the lutter is revolved the roller,I (i7 will enlerthe slot of one arm of the stu-r wheel, and the continued rota-tion of the geur wheel 8 will turn such ster wheel on its pivot for (in the arrangement shown) exactly one third. ot' o revolution, and as sleeve G3 connects the stur wheel with head 52 carrying rollers 4S, such head will also be turned 'for n third of a revolution, bringing another roller 4S into operative position, und the one that has just operated into n convenient position for the l removal of the rolled blank. y y

In order to insure that'the star wheel und parts connected therewith shall be brought to rest in their correct positions the arrangement shown ut the lett of Fig. l may be employed, comprising a. pivuted catch or dog 68 the nose of Which is caused to enter the slot of one of the arms of the stur .wheel 65 immediately the latter :t1-rires :1t its stopping position, and which remains enga-ged with such slot until the star wheel is justy about to movengcin. The catch 68 is acted upon by cams 69 formed on gear wheel S. against the action of :1 Spring 70 which tends to normally hold itin engagement. with the star wheel. r

As hereinbefore stated tliestripper 56 is 'preferably arranged to be operated lifter the x'oller'48 carrying u. rolled blank has been turned to a position out of the path of trarel'of the 'pile of blanks,4 thus kfncilitnting the subsequent removal of such rolled blank by hand by the attendant.
