MACHINE FOR MAKING CIGARETTE MOUTH-PIECES.

SPECIFICATION forming part of Letters Patent N 0. 403,324, dated May 14, 1889.

Application filed October 23, 1888. Serial No. 288,894. (No model) To all whom, it may concern.-

Be it known that 1, SAMUEL BROWN, a citizen of the United States, residing at Seaford Hundred, in the county of Sussex and State of Delaware, have invented new an'd useful Improvements in Machines for MakingPaper Cones and Tubes Suitable for Mouth-Pieces for Cigarettes, of which the following is a specification.

My invention relates to machines for making paper cones or tubes, especially such as are used as mouth-pieces for cigars and cigarettes.

. The improved machine comprises a rotary drum or carrier, preferably provided at both ends with a number of intermittingly-rotating mandrels on which the tubes of paper are formed, reels for supplying the paper, mechanism for feeding the paper from the reels to the mandrels and for cutting it after it has been partly wound or coiled, means for pasting the paper coils, dies for pressing the paper coils into the shape of elongated paper cones, and ej ectors for removing the completed cones. The rotary drum or carrier supports the mandrels, reels, feeding and cutting mech anism, presser-feet for the paper coiled on the mandrels, the dies, the ejectors, and a portion of the actuating mechanism of said devices, other parts of the actuating mechanism being supported by the machine-frame, while the pasting mechanism is supported in front of the rotary drum or carrier.

My invention consists in the construction and combination of devices hereinafter described and claimed, and illustrated in the annexed drawings, in which Figure 1 is an end elevation of my improved machine for making paper cones or tubes, such as mouth-pieces for cigars and cigarettes. Fig. 2 is a plan of the same with parts broken away and parts in section to illustrate the general construction of the machine more clearly. Fig. 3 is an enlarged detail view of a portion of that end of the machine shown in Fig. 1, illustrating mechanism for feeding a paper strip from a reel to a slotted rotary mandrel which travels in a circular path, showing also in dotted lines a tappet fixed on the mandrel-shaft, which tappet is actuated by a spring-pressed cam in such a manner as to cause the mandrel to unfailingly present its slot in proper position to receive the paper strip, and showing, further, a presser-foot and a portion of the mechanism for forming a paper cone on the mandrel. Fig. .4 is an enlarged detail view of a portion of the same end of the machine, illustrating the manner of cutting the paper strip and applying paste to its outer end after it has been wound on the mandrel and before said strip is formed into a cone,which is subsequently effected by the continued rotation of the mandrel in proximity to the pressenfoot and by the action of a former or die that is automatically slipped onto and off of the paper coil. Fig. 5 is an enlarged detail view of the same end of the machine, showingthe mechanism for ejecting the paper cone from the mandrel, the cone former or die being shown as thrown out of action and the paper-feeding devices being removed. Fig. 6 is a plan of the slotted mandrel, the presser-foot, the cone-former, the ejector, and connected parts. Fig. 7 is a longitudinal section of a pair or set of rotary tubular mandrels and inclosed expander-s, with mechanism for actuating said mandrels and expanders, and showing also a portion of their rotary supports in section. Figs. 8, 9, and 10 are sectional detail views illustrating the progressive steps of coiling a strip of paper onto the reduced cylindrical portion of a tubular, split, or slotted mandrel, forcing a portion of said coil onto the conical part of the mandrel by means of a former or die, whereby the paper cone is formed, withdrawing the said former and throwing it to one side, retracting the expander to allow the mandrel to collapse, and finally ejecting the paper cone. Fig. 11 is a view of the paper cone and the paper-coil from which it is formed. Fig. 12 is an end view of a tubular and partly-conical split mandrel. Fig. 13 is a view of the tappet on the mandrel-shaft. Fig. 1a is a sectional side elevation of the paper-feeding mechanism. Fig. 15 is a front or edge elevation of the same with upper portion removed. Fig. 16 is a section on the line 16 16 of Fig. 14:. Fig. 17 is a sectional view of the paster-arm. Fig. 18 is a partly-sectional detail elevation viewed from the end of the machine opposite to that shown in Fig. 1, illustrz'ttingthe mechanism for rotating the inandrels.

The supporting frame-work. of the machine comprises end standards, 1, of any suitable form, which are firmly braced, as shown. in Fig. 1, and maybe secured to the floor. These standards are connected at the top by a fixed shaft, 2, which extends across the machine from end to end.

On the fixed shaft 2 is loosely mounted a rotary drum or hollow cylindrical carrier, 3, the heads or ends of which consist of gearwheels l, which are of larger diameter than the body of the drum. This drum or carrier is rotated through the gears -l, meshing with pinions 5 on a power-shaft, 6, having fast and loose pulleys 7, as shown in Fig. 2.

To each end of the fixed shaft 2, beyond the ends of the drum, are secured two stationary radial arms, 8 and 9, which support at their outer ends a concave hood, 10, that forms about oi'ie-quartero'f the periphery of the machine. The radial arms 8 and Qfith each end of the machine, are formed on hubs 1.1,wl1ich are secured to the fixed shaft 2, as shown. The arms 8 are vertical, and the arms 9 are inclined bacluvard, thereby supporting the hood at the upper part of the rear side of the machine. The concave hood 10 is necessarily formed on the are of a larger circle than that of the gears 11', and it is also of greater width than the drum to which said gears are attached. The hood 10 supports on its under side certain cams, which will be hereinafter referred to in describing other parts of the machine. The rotary drum 3 is adapted to carry at each end anun'tber of intermittingly rotary mandrels, 12, on which the paper cones are to be formed. These mandrels project in axial line beyond the ends of the drum, and each 1namlrel-shaft is connected with the shaft of a corresponding mandrel at the other end of the drum, the two mandrels thus connectcd constituting a set or pair in whichboth mandrels are simultaneously actuated, so as to be engaged at the same time in winding the paper strip or in sumnin'ting the coiled paper strip while it is acted on by other devices.

In the drawings I have shown at each end of the drum four intermittingly-rotary mandrels arranged at equidistant points; butIdo not wish to confine myself to any particular number, as it is obvious that they can be increased or diminished, and those at either end of the machine can be dispensed with entirely.

13y referring to Figs. 2 and 7 it will be seen that the mandrel-sha'fts 1.2" are supported or journalcd at their outer ends in suitable openings made in the gears 4;, outside the periphery of the cylindrical portion of the drum 3, their inner ends being supported in perforated lugs 13 on the drunrbody.

()n the mandrel shaft, or partly on' the shafts of each pair, is a fixed pinion, ll-,\\'hieh serves to rigidly connect the adjoining .ends of the two shafts in each pair, as shown. in Fig. 7, when both ends of the drum or carrier 3 are provided withmandrels. Each mandrelshaft is rotated. through its pinion 1-1 from an il'itermcshing gear, 15, having its shaft 16 iournaled in yielding boxes 17, supported in hangers or brackets 18, attached to the inner surface of the drum 3 at suitable intervals, said drums being provided with slots 19 to enable the several pinions 14- and 15 to be engaged.

By referring to Figs. 2 and 18 it will be seen that on the gear-shaft 10 is rigidly secured a circumferentially-grooved frictiolr wheel, 20, which is adapted to engage correspondiugly-grooved arc-cams 21 and 22 on the periphery of a mutilated friction-disk, 22;, which is fixed to the statiol'lary shaft 2, on which the drum 3 rotates. Between the areshaped cams 21 and 22 the periphery of the friction-disk 23 is cut away to form at one point a comparatively short depressed surface or recess, 2i, and at another point a similar recess, 25, of greater length. Each grooved friction-wheel is pressed into frictional contact. with the arc-cams 21 and by means of springs 26, with which the journal-boxes of the Shaft 16 are provided; but the supports of said journal-boxes are so arranged as to prevent the friction-wheels 20 from coming in contact with the depressed or recessed portions of the stationary disk 3 between said are-cams. It will therefore be seen that the mandrels 12 will be rotated through the pinions 1-1:, gears 15, and grooved :lrictioirwheels 20, while said. friction-wheels, carried by the drum 3, are moving along the arc-cams 21 and but will cease to rotate while the frictiom wheels 20 are passing the recesses 24. and 25 between the arc-cams. During the rotation of the drum .3, (in the direction of the arrows shown in Figs] and 1S,whieh are views from opposite ends of the machine,) the several friction-wheels 20 are carried in succession into contact with and along the are-cam 3], thereby successively rotating each mandrel or pair of mandrels and winding thereon the paper strip which is being fed to said man.- drel. Each mandrel is accompanied by a presser-foot, hereinafter described, whereby the paper strip is held in close contact with the mandrel while it is being wound thereon. \Vhile the mandrel or pairs of mandrels and actuating-gtziars are passing the short recess El the mandrel ceases to rotate, the paper strip is cut, and paste is applied. to its projecting cut end. In passing the arc-cam 22 the mandrel is again rotated in contact with the presser-foot to compactthe coil of paper and allow sufficient time for its pasted end to become dry and be firmly secured. The presser-foot is then automatically thrown aside, and as the mandrel-actuating mechanism passes the longer recess, 25, a hollow former or die is automatically slipped onto the coil and presses it backward and into the shape of a cone, conforming to the conical part of the mandrel, and said mandrel is made to present its slot in proper position to receive another supply of paper before the frictional contact of the grooved wheel and arc-cam 21 cause the mandrel to again rotate. These several operations require the employment of various devices, which will be described in detail.

Each mandrel 12 is formed with a tubular shaft, 12, having a bore which is continuous with that of the hollow or tubular mandrel. The inner end of this bore in the mandrelshaft is enlarged for the greater part of the length of said mandrel-shaft, as shown at 12 in Fig. 7. The hollow mandrel 12 is formed with a conical portion, 12, a reduced cylindrical portion, 12, and a longitudinal cleft or slot, 12 Figs. 6 and 12, which extends through the mandrel from side to side throughout the length of said conical and reduced cylindrical portions. This slot 12 is to receive and hold a portion of the paper strip to be wound or coiled on the cylindrical outer end of the mandrel, Fig. 8, and subsequently formed into a cone, Figs. 9, 10, and 11, 011 the conical portion of the mandrel.

In the tubular mandrel 12 and mandrelshaft 12 is a conically-pointed expander, 27, in the form of a rod or shaft, Fig. 7, having an enlarged cylindrical portion, 27, which is inclosed in the enlarged portion of the bore 12 formed in the mandrel-shaft. A spring 28, pressing against the inner enlarged end of the expander-shaft 27 normally forces the conical expander 27 outward within the tubular slotted mandrel and expands it so that the paper strip can readily enter the slot 12 and be coiled tightly and closely on the cylindrical portion 12. As shown in Fig. 7, this sprin 23 is located between the opposite mandrel-expanders.. The mandrel-shafts 12 are provided with slots 30, for the passage of pins or rivets 29, which are passed through the enlarged portions 27 of the expandershafts and connect them with friction-wheels 31, that are mounted on the mandrel-shafts. At a proper point in the circular travel of the rotating mandrels (when the paper cone is completed and before it is ejected,) the friction wheels 31 come in contact with cams 32, that are attached to the underside of the hood 10, thereby retracting the expanders and causing the tubular slotted mandrels to collapse sufficiently to loosen the cones and enable them to be readily removed without injury, as hereinafter explained. After the removal of the paper tubes or cones the disengagement of the wheels 31 and cams 3.. enables the spring 28 to again press the expander-s 27 outward within the tubular mandrels.

The paper strips 33 are supplied to the mandrels from reels 34, that are mounted on the ends of the rotary drum or carrier. Each reel 34, as shown in Figs. 1 and 3, is accompanied with a papenfeeding mechanism, Figs, 3, 14,

1 5, and 16, which comprises a lever, 35, that is pivoted between its ends to a stud, 36, projecting from the end of the drum. On the rear edge of each lever 35, or that edge which is nearest its accompanying reel, is a guideway, 37, for receiving the paper strip. This guideway is parallel with the lever 35, and is located at the Outer end of said lever, as shown in Figs. 3 and 14. That end of the guideway 37 which is nearest the reel is curved outward, as shown, so as to provide for the proper feeding of the paper strip without liability of its becoming broken 'or torn by abrasion against the entering end of said guideway, especially when the angle of feed is increased by the diminishing diameter of the roll of paper on the reel. The outer end of the lever is perforated from front to rear by a recess, 38, which extends through the guideway 37 for receiving the feed-wheels. One of these feed-wheels is an idler, 39, that is journaled in lugs 40 on the rear edge of the lever. The other or main feed-wheel, 41, is journaled in the bifurcated end of a finger, 42, which is pivoted in lugs 43 on the front edge of said lever. The finger 42 is held in position by means of a spring, 44, and it may also be provided with an adjustable screw or pin, 45, for a purpose hereinafter explained.

The shaft of the feed-wheel 41 carries on the outside of the lever 35 a friction-wheel, 46, which is so arranged as to come in contact with and travel along a curved track or cam, 47, supported by the adjacent vertical stationary arm 8, and thereby rotate the feedwheel 41, so as to draw on the paper strip 33, and gradually feed it, with the assistance of the idler 39, through the guideway 37 and along the rear face or edge of a lug, 48, that is secured to the cylinder-head or gear 4 in a suitable position adjacent to the point where a mandrel projects. A star-wheel, 49, supported by the lug 48, serves to hold the paper strip in contact with said lug and guide it unfailingly to the slot or cleft 12 in the man-.

drel.

In order to hold the. pivoted lever 35 in its normal position, with the guideway 37 in line with the rear face of the lug 48, the outer end of said lever is provided with a flange or projection, 50, to bear rearwardly against the front edge of the lug 4S, and a spring, 51, is coiled 011 the stud 36' and has one end attached to the lever 35 and its other end attached to the gear 4, on which said lever is pivotally mounted. By the action of this spring 51 the lever 35 is held with its flange or projection bearing normally against the front edge of the lug 48, so as to enable the paper strip to be fed through the guideway 37 along the rear edge of said lug to the mandrel. In order to enable the paper strip to enter the mandreh slot 12*, it is necessary that the mandrel should be caused to present its said slot in proper position in line with the path of said paper strip. This is accomplished by rigidly mounting on the mandrel-shaft a doubleended tappet, Figs, 7 and 13, and pivoting to the undcrsideof thchood 10 a yielding cam, 53, Figs. 1 and 3, to coact with said tappet at the proper time in throwing the mandrel. around with its slot in line with the path of the paper strip.

it will be seen that the tappet 52 is formed with a curved or lenticular periphery pointed at both ends, and that it is centrally-mounted on the maiulrel-shaft at right angles to the nmmlrel-slot112, which is to receive the paper strip. The yielding cam 53 is pivotally supported at its forward end beneath a slot, 54, in the hood l0, and is pressed downward by a spring, 55, which secured to the outside of the hood and projected through said slot onto the upper edge of the cam, a stop, so, being attached to the under side of the hood .in contact with the forward end of the pivoted cam to limit its downward movement under the pressure of the sprin 55, while the slot 54 enables it to rise sufficiently against the pressure of the spring55 to acconnnodate itself without unnecessary friction to the pressure of the tappets on the mandrels carried by the rotating cylinder. During the retation of the carrier or cylinder each mand rel-shaft and attached tappet 52 is brought in succession beneath the slightly-curved lower edge of the yielding cam 53, and if the slotted mandrel is not already in proper position to receive the paper strip the frictional contact of said tappet and cam will revolve the mandrel sufficiently to bring its slot 12" in line with the rear edge of the lug 48, over which the paper strip is fed. The end of the paper strip having been fed to the expanded mandrel into and through the slot 12, the continued rotation of the carrier 3 will carry the friction-wheel it along the curved stationary track +t7, thereby unrccling the paper strip and feeding it continuously to the mandrel with a positive movement, due to the direct action of the feedwheels is and 41, and by the time the friction-wheel to clears the track :7 the grooved friction-wheel 20 will engage the arc-cam 21 on the stationary frictiomdisk 23, and through the gears and 1-1- will rotate the mandrel-shaft with which the paper strip is engaged, thereby continuing the unreeliug of the paperstrip and causing it to be wound on the cylindrical portion 12 of the mandrel in contact with a presser-foot, to be presently described. By this means the paper strip is wound on the cylindrical portion of the mandrel 12 in a close coil, as shown in Fig. 8. After passing in a forward direction along the entire length of the arc-cam 21 the friction-wheel passes over the short recess 24. on the periphery of the stationary disk 23, and being now out of frictional contact with said disk the wheel 20 and connected gears come to rest, and consequently the mandrel ceases to rotate. At this point in the rotation of the carrier 3 the paper strip is severed by the action of a knife or cutter, 57, mounted on the rear edge of the pivoted lever 35, at the outer end of the guideway 37, through which. the paper strip is passed. \Vhen the lever is in its normal position, with its flange hearing against the front edge of the lug 4C8, under the action of the spring 51, the knife 57 is at a sufficient distance from the rear edge of the lug 4.8 to afford a free passage for the paper strip on its way to the mandrel; but when it becomes necessary to sever the paper strip the pivoted lever 35 is tri 'iped and forced forward against the pressure of the spring 51, so as to carry the .knife 57 forward and cut the strip of paper against the adjacent edge of the lug 4:9, as shown in Fig -t. This action of the pivoted lever 35 and its attached knife 57 is accomplished by means of a trippingroll, 58, mounted on an arm, 55.),whichis rigidly secured to the fixed shaft 2 and projects tl'lerefromin a forward direction, as shown in Fig. 2, in the path of a friction-roll, 60, that is mounted on, an inwardly-proj ecting arm,6l Fi 15 and ii (3, 0f the lever 35, which arm is passed through a slot, 62, in the end of the rotating drum or carrier. During the greater part of each revolution of the drum or carrier the rolls 5% and 00 are out of contact with each other; but when each lever isbrought into a horizontal and fm'wardly-proj ectin g position, after the paper strip has been wound on the cylindrical portion of the adjacent mandrel, the roll 60 eonies in frictional contact with the roll 58 on the stationary arm 5!), and the lever is tripped or pressed forward and downward against the tension of its spring 511, and the knife 57 is thus caused to sever the paper strip.

In front of the rotating carrier 3, as shown in Figs. 1. and 2, are placed a pair of standards, 63, each of which supports a pastefountain, ($4, in which is j ournaled a fountai nroller, 65, for taking paste from the fountain (it and supplying it to an auxiliary roller, 60, journaled in suitable bearings above the rear side of the fountain. The two fountain-rollers one for each side or end of the macl1ineare firmly mounted on a shaft, (57, having a pulley, (38, through which the rollers 65 are driven by belting 69 from a countershaft. (Not shown.) On the rear of each fountain 64 are bearings 7 O for a shaft, 71, on which are rigidly mounted a pair of flexible paster-arms, 72, the construction of which is shown in Fig. 17. By reference to this figure it will be seen that the flexible paster-arm 7 2 is made in two parts connected by a hingejoint, 73, and having in one part a springactuated bolt, 74, provided with a pointed or conical end to normally engage anotch, 75, in the jointed end of the otherpart, and thereby hold said paster-arm extended, with both parts in the same line.

011 the underside of the joint 73 both parts of the pastor-arm 7 2 are formed with beveled or rounded corners 7 0, to enable the joint to be broken, as presently explained. In the outer end of each paster-arm is journafled a paster-roller, 77, for applying paste to the severed end of the paper strip. A weight, 7 8, is connected by a cord, 79, to a grooved pulley, 80, that is securely mounted on the shaft 71, so as to rotate said shaft in a forward direction, or toward the paste-fountains, thereby elevating the paster-arms and carrying the paste-rollers 77 into contact with the rollers 66, as shown by dotted lines in Fig. 1, to receive a supply of paste. lVhen the weight 78 carries the flexible paster-arm 72 against the roller 66,the joint 7 S is broken down, so as to bring the beveled corners 76 together and flex said arm. At suitable points on the periphery of the rotary cylinder 3 are lugs or wipers 81, so arranged that after the paper strip has been cut or severed, as hereinbefore explained, one of the wipers will come in contact with a friction disk or pulley, 82, on the shaft 71, and so rotate said shaft backward, thereby raising the weight 78 and carrying each flexed pastor-arm 72 backward and downward to bring its paste-roller 77 in contact with the projecting uncoiled end of the paper strip on the lug 48, as shown in Fig. 4. The flexed position of the paster-arm 72 en ables the roller 77 to apply paste along the projecting portion of the paper strip all the way to its end, and as the roller 77 thus travels over the paper strip the flexed arm 72 is gradually extended until the spring-actuated bolt 74 again engages the notch 75, and so holds the pastelarm extended until it is again raised by the action of the weight 78 into contact with the roller 66 to receive another supply of paste. After paste has thus been applied to the paper strip the continued rotation of the carrier 3 disengages the rolls 58 and 60, thereby enabling the spring 51 to restore the lever 35 to its normal position with the flange 50 in con tact with the lug 48, and with the knife 57 retracted in position to again sever the paper strip at the proper time. The rotation of the drum or carrier 3 next brings the grooved friction-wheel 20 in contact with the grooved arc-cam 22, along which said friction-wheel travels, and thus, through the gears 15 and 14, causes the mandrel to again rotate on its axis and wind or coil the pasted portion of the paper strip.

0n the outersides of the gear 4, in advance of each mandrel, as shown in Fig. 1, is a boss, 83, Fig. 6, which supports an angle-ar1n,84, on which is pivoted a presser-foot, 85, that is normally pressed by a spring, 86, in contact with the cylindrical portion of the mandrel, as shown in Fig. 3, or with the strip of paper coiled thereon, as shown in Fig. 4. \Vhile the friction-roll 20 is traveling along the arccams 21 and 22, thus rotating the mandrel, and also during the time that the rotation of the mandrel is suspended while the paper strip is being cut and pasted, the presser-foot is held by its spring 86 in flrm contact with the periphery of the paper that is coiled on the i'nandrel, thereby compacting it closely and exerting such pressure on the pasted end of the coil as to cause it to adhere securely.

In the outer end of the presser-foot S5 is journaled a roller, 87, which in passing beneath and in contact with a cam, 88, on the under side of the hood 10, as shown in Figs. 1 and 5, throws the presser-foot to one side out of contact with the pasted paper coil on which the paste has by this time become sufficiently dry to enable the coil to be formed into a cone or tapering tube. Just before the presser-foot 85 is thrown aside the frictionwheel 20 clears the arc-cam 22, and the mandrel therefore ceases to rotate while its actuating-gears are passing the long recess 25, during which time the paper coil is formed into a conical tube and ejected from the mandrel.

On the inside of each gear 4 are a number of brackets, 89, one of which is shown in Fig. 6. Each bracket 89 has a bearing, 90, for a shaft, 91, which passes through. the gear 4 and boss 83 and carries a friction-roller, 92, in its bifurcated outer end. On the shaft 91 adjacent to the inner side of the gear 4 is a fixed collar, 93, which affords a bearing for one end of a spiral spring, 94, that is coiled around the inner portion of said shaft, the other end of the spring being supported against the bearing on the bracket. The collar 93 has an arm, 95, which projects beneath along pin or stud, 96, on the inner side of the gear 4, and a curved spring, 97, is secured at one end to the under side of the arm 95, as shown by dotted lines in Fig. 5, and is bent around the collar 93 and over onto the pin 90 on which it bears.

On the arm 95 is mounted a friction-roller, 98, and on the shaft 91, near its outer end, is a lateral arm, 99, which carries at its end a tubular die or former, 100, having a conical bore, (indicated by dotted lines in Figs. 6 and 10 and clearly shown in Figs. 8 and 9,) which bore corresponds with the taper to be given to the coil of paper on the mandrel. By the expansive force. of the spiral spring 94 the shaft 91 and connected die are forced normally outward, an d by the action of the spring 97, having the pin 96 as afulcrum, the arm 95 and attached roller 98 are raised or inclined upward and the arm 99 and attached die 100 correspondingly depressed or inclined downward with the die or former 100 normally in line with the mandrel. After the presserfoot 85 has been thrown aside by its roller 87 engaging the cam 88 the roller 92 on the outer end of the shaft 91 comes in contact with a cam, 101, on the inclined hood supporting arm 9, thereby forcing the shaft 91 and collar 93 inward against the pressure of the spiral spring 94 and carrying the tubular die or former 100 against and around the coiled and pasted paper strip on the mandrel. This movement of the die 100 in the direction of the arrow shown in Fig. 8 forces the outer coils of the paper tube 102 back onto the conical portion 12 of the mandrel, as shown in Fig. 0, and produces a conical spirally-coiled paper tube, 10-3, of the form shown in Figs. 10 and 11., in which only a small portion of the successive inner spiral coils are exposed, thus making a strong and durable spiral tube or cone suitable for various uses. \Vhen the roller 02 clears the cam 10], the spiral spring 0 forces the shaft 01 out and removes the die 100 from the mandrel, after which the roller 03 engages a cam, 101-, on the inner side of the bond 10, thereby depressing the arm 08 so as to rock the shaft 91 and elevate the die 100 out of line with the mandrel. to permit the removal of the paper tube or cone.

It will be seen that the long pin or stud 90, Fig. 6, serves as a fulcrum for the spring 07 in depressing the die 100, and also as a guide for the arm 05 and spring 07 during the iongitudinal movement of:' the shaft 01, by which said die or former is carried.

On each maiulrel-sha'ft ismounted a sliding non-rotatable cross-head, 105, which is connected by rods 100 with an annular ejector, 107, that surrounds the mandrel. To the crosshcad 105 is connected the bifurcated end of a lever, 108, that is pivoted to the inner side of the gear 4-, and provided with a frictionroller, 100, which aft'ords a bearing for a spring, 110, attached to the inner side of the gear 1-, as shown in Fig. 2. By the action of the spring 110 on the lever 108 the crosshead 105 and connected ejector are normally held in a retracted or inactive position on the mandrel. After the die 100 has been removed from the mandrel the expander 27 is retracted against the pressure of the spring 28 by the engagement of the frictiongear 31 with the cam 32, thus pcrn'iitting the split or slotted mandrel to collapse sufficiently to loosen the paper cone or tube, and the continued rotation of the drum or carrier 3 brin a frictionroller, 11], Fig. 2, on the ejector-level 108, in contact with a cam, 112, on the side of the fixed friction-disk 23, thus actuating the lever108 and connected ejector 107, so a-s to push the paper tube or cone off from the mandrel without breaking or otherwise marring said tube. The friction wheels or gears 31 now clear the cams 3i a-nd permit the spring 28 to press out the cxpanders 27 and dilate the slotted tubular mandrels. The rollers 87 next clear the cams S8, and thus permit each spring-actuated presserfoot to come into position at the side of its accompanying mandrel, and the tappet 52 in passing beneath the cam 53 causes both mandrels of that pair to present their slots 12 in position to receive the ends of the paper strips which are fed to them from the reels 31-. by the action of the feed-wheels and their actuating friction-wheels -10 in passing over the cam-tracks -17, as before explained. \Vhilc the drum or carrier 3 continues to rotate the successive operations of expanding the several. mandrels in turn and presenting them in proper position, throwing the presser-icet intoaction,

feeding the paper-strips to the mandre1s,coi.ling, cutting, and pasting the paper strips and causing their pasted ends to adhere, removing the presser-feet, throwing the cone formers or dies into action, retractin the expanders to collapse the slotted mand rels, withdrawing the dies, and, .finally, ejecting the completed paper cones or tubes, are carried on at different point-s in the machine, as hereinbefore described. The paper cones or tubes thus made may be waterproofed, enameled, or otherwise finished in any well-known manner to better fit them for the various pu1- poses to which such articles are applied.

It will be understood that the rotary drum or carrier 3 may support one or more mandrels and accompanying mechanism at either or both ends, although four mandrels with. corresponding sets of. accompaniments at each end of a rotary drum are preferable as at fording a convenient arrai'igeineiiit of mechan ism for rapidly and economically produein g the paper tubes in large quantities.

As shown in Fig. 7, the periphery of the hollow drum 3 is provided on both sides of the lugs 13 with recesses 113, to afford room. for the gears 11, 15, and 31, tappets 52, and sliding cross-heads 105, and on each. mandrelshaft 12, at one side of the lug 13, a fixed collar, 111-, to assist the pinion 1st to prevent endwise movement of the maiulrel-shat't in its bearings. The hollow drum 3 also has slots 115, for passage of the ejector-levers 108, as shown in Figs. 2 and 7.

By means of the levers and coacting devices carried by the drum 3, as described, the paper strip is properly and smoothly fed from the reel 34L, through the guideway 37, between theieed-whcels 3.) and 41, and over the lug 4:8 to the slotted mandrel 12, into which it readily becomes engaged. The proper action of the feeding mechanism carried by the lever 35 is il'nproved and facilitated by mounting the main teed-wheel 4:1 in a pivoted slightlyyielding finger, -12, that held in place by a spring, 4.4., or by an adjustable screw or stop-pin, +15, as shown in Fig. I1.-.l-. .ly this coi'lstruction a positive .t'eed is given to the paper strip until after its ongagement with the slotted mandrel, and thus as the mandrel begins to rotate the grip of? the feed-wheels on the paper strip is relaxed, so as to enable the rotating mandrel to draw the strip of paper from the reel, as required, without any strain or risk of tearing. In order to hold the yielding finger 12 in place, either the spring +l--1- or the adjustable screw may be used alone. \Vhen. the spring 4-1 is not used, or should it become broken or disabled, the screw or pin. -15 can be adjusted with sufficient nicety to insure a proper action of the finger, and by providing the lever with both of said devices the adjustable screw is at once ready to take the place of a broken spring in case of accident.

The various devices for coiling cutting, and pasting the paper strips, and for Forming and ejecting the conical paper tubes, as shown in Figs. 8, 9, and 10, are so constructed and arranged as to act in proper time and simultaneously at both ends of the machine.
