MOUTH-PIECES OR PAPER TUBES SPECIFICATION forming part of Letters Patent No. 400,7 65, dated April 2, 1889.
Application filed August 4, 1887- To all whom it may concern.-
Be it known that we, GEORGE M. GRlswoLn, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, and ROBERT WV. THURMAN and RICHARD H. WRIGHT, citizens of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented new and useful Improvements in Machines for Making Cigarette Mouth- Pieces or Paper Tubes, of which the following is a specification.
The object of this invention is to provide an automatic machine for making cigarette mouth-pieces or holders from a continuous pa per strip cut into blanks of proper shape,which are to be consecutively supplied on one edge with an adhesive substance, as required, then wound into the desired form, partially coated with paraffine or like substance, and ejected from the machine in a finished condition.
To this end the invention consists in a machine comprising the various devices and combinations of parts, as hereinafter more particularly described, and fully set forth in the claims.

The frame of the machine comprises a table, 1, supported on legs or standards 2 in any suitable and convenient manner. At the rear end of the machine-frame, beneath the table 1, are bearings or journal-boxes for a power-shaft, 3, carrying a fiy-wheel, 4, at one end and provided at the other end with a driving-pulley, 5, which is preferably furnished with any suitable clutch mechanism, 6, actuated by a hand-lever, 7, so as to permit the driving-pulley to be made fast or loose on said shaft, as required. The power-shaft 3 also carries a small spur-gear, 8, which mesheswith and drives a large spur-gear, 9, secured Fig. 16 shows one to a cam-shaft, 10, supported in suit-able bear-'1' ings beneath the table or bed 1 in advance'of' the powensha-ft.
Above the rear end of the table 1, near one set of straightening-rollers, 14, supported by a bracket, 15, secured to the top of the table. The first of these straightening-rollers 14. is provided with adjustable guide-collars 16, as shown in Figs. 2, 3, and 5, to hold the moving roll of paper in proper alignment, and the third roller in the set is vertically adjustable by means of a slot and thumb-screw, 17, as shown in Fig. 1, to vary the friction on the roll of paper as may be required to remove creases and make the paper smooth. From the straightening-rollers 14 the paper strip 13 passes to a pair of feed-rollers, 18, Fig. 5, journaled in bearings 19 above the table. These feed-rollers are provided with small drivinggears 20, Fig. 1, driven by a large gear, 21, actuated by a pawl-and-ratchet mechanism, 22, carried by pivotally-conneeted levers 23 24., which are put in motion by a crank, faceplate, or eccentric-disk, 25, on the cam-shaft 10. The shaft 26 of the gear 21 may be supported in halved bearings 27, movable on a base-plate, 28, secured to the table, as shown in Figs. 2, 3, and 5, to facilitate adjustment of the gear. V
I11 front of the feed rollers 1.8 is an anvil or die-block, 29, the top of which is slightly below the level of the space between the feedrollers.
To the front of the roller-bearings 19 is secured a clearing-plate, 30, Fig. 6, which projects above the dic-block 29 in approximately a horizontal plane. This clearing-plate 30 comprises an attaching portion or bar, 31, from one end of which extends a downwardlyprojecting neck, 32, carrying a broad plate, 33, the outline of which is approximately that of the paper blank to be out. At the other end of the attaching-bar 31 is a downwardly and forwardly proj ccting neck, 34, formed with a forwardly-projecting wing, 35, having a downwardly and rearwardly inclined lip, 36.
Between the bar 31, necks 32 34., and wing is an opening, 37, for passage of the paper strip 13 over the wing 35, and between the front edge of the wing 35 and rear diagonal edge of the plate is an opening, 38, to permit the passage of the paper strip 13 beneath the plate 33 to the space between the clearing-plate and die-block.
Above the die-block 29 and patterngage 30 is suspended avertically-reciprocating punch or cutter-head, 39, Figs. 13 and 14, carried by a plunger, 40, moving in a vertical guideway,
41, formed in a bracket, #12, Figs. 1, 3, and 5,
supported on the machine-table. This plunger and attached cutter-head 39 are actuated through a lever, 43, fulcrumed to the rear upper portion of the bracket 12 and pivoted at its rear end to the upper end of a connecting bar or lever, 41, the lower end of which is pivoted to a lever, 4:5,fulcrun1ed at one end on a fixed transverse rod, 46, supported by brackets 47,projecting from the supporting framework of the machine. The lever carries a small frictionn'ollel', 48,Fig. 5, engaged in the cam-groove or race 49 of a cam-disk, 50, secured to the cam-shaft 10, and by which the levers 4:5 11 13 and connected cutter-head 39 are actuated. I
, The form of the reciprocating cutter-head 3S) and its attached knives 5], 52, 53, 54., and is shown in 1, 5, 13, and let. It will be seen that the several knives correspond in inclination and curvature with the form of the blank to be out, as shown in Figs. 16 and 17. The first descent of the cutter-head upon and around the clearing-plate cuts the end of the paper strip 13 beneath said plate into the shape shown in Fig. 16, thereby nearly forming a blank, but leaving it integral with the paper strip at the point 56, so that the incomplete blank will be fed forward with said paper strip as the cutter-head ascends. On the next downward stroke of the cutter-head this incomplete blank will be severed on the line 56 by the forward knife, 51, thus completing the blank 57, as shown in Fig. 17, and partly forming another blank on the end of the paper strip. In this operation the clear= ing plate 30 above the blank serves to pro; vent said blank from rising with the receding knives. The upper surface of the die-block 29 may be faced with a steel wearing-plate, 58, Fig. 1, secured by screws passed into openings 59, Fig. 15, in the top of the die-block. As shown in Fig. 15, which represents a plan or top view of the die-block with the wearingplate removed, it will be seen that the upper surface of said block corresponds with the outline of the blank to be formed and that it is provided at the bottom with a baseflange, 60, through which it is secured to the machine-table.
At the front end of the machine is located the mechanism for making from the blank 57 a papertube adapted for use as a cigarette holder or mouthpiece. This mechanism comprises various devices which will now be described in connection with the means for operating the same.
In order to eiiiect the manufacture of the paper tubes or cigarette-holders in large quantities with ease and rapidity, a number of rotary mandrels are mounted in a rotary support or carrier, 61, of circular form, keyed centrally to a vertical shaft, 62, having a bearing in a journal-box, 63, bolted to the under side of the machine-table. The shaft-62 and attached mandrel-carrier 61 are rotated intermittently by a pawl-and-ratchet mechanism, 64, of any suitable construction, actuated through the bent. levers 65 66, connected by a slotted link, 67, one end of the bent lever 66 being pivoted to the upper arm of a bellcrank, 68, fulcrumed on the fixed shaft or rod 46, and having its lower arm provided with a friction-roller, 69, Fig. 1, engaging a cam-race, '70, in a cam-disk, 71, carried by the cam-shaft 10, from which the mandrel-carrier 61 is thus actuated. In order to prevent backlash an ordinary spring-pawl, 72, Figs. 2 and 4, is provided.
The periphery of the rotary carrier 61 is pierced at regular intervals for receiving the steel wearing-collars 73, that afford bearings for the body portions of the rotary mandrels 74, employed in making cigarette holders. These mandrels '74 project radially from the circular carrier 61, and have a tapering form, small at their outer ends and enlarged at their rear portions, where they are supported in the periphery of the carrier.
One dozen mandrels are shown in the draw ings; but it is obvious that a machine can be made with a greater or less number. Each mandrel 71 is provided with a stem or shank,
7 5, the rear or inner end of which has a bearing in a steel Wearing-collar, 76, a number of which are supported in an annular projection, 77, depending from the top of the carrier 61, near its hub 78, Figs. 7 and 8. The carrier-hub 78 is perforated radially to receive adjustable thrust-bearings 79, that are arranged in line with the several mandrels.
. On each mandrel-stem is secured a bevelpinion, 80, which meshes with a circular rack or bevel-gear, 81., placed loosely around the carrier-shaft 62 beneath the mandrels. This rack or gear 81 is actuated by a suitable pawl or ratchet mechanism, 82, provided with means for preventing backlash, as usual. The driving-pawls 83 of this ratchet mechanism 82 are mounted on horizontally-arranged bell-cranks 84. (Shown by dotted lines in Fig. 7.) These bell-cranks 84 are connected to a lever, 85, which is pivoted to the upper arm of a bellcrank, 86, f ulcrumed on the transverse rod 46, and having its lower arm provided with a friction-roller, 87, Fig. 2, engaged in the camrace 88 of a cam-disk, 89, on the shaft 10, whereby the tube-forming mandrels 74 are rotated.
As clearly shown in Fig. 8, each rotary mandrel 74 is hollow and provided on its top with a longitudinal slot, 90, extending to the outer mandrel end. In this hollow mandrel is pivoted a latch or dog, 91, for gripping one corner of the blank to be formed into a tube or cigarette-holder. In the enlarged body portion of the mandrel, beneath the rear end of the dog 91, is a spiral spring, 92, which expands against the under side of the dog at its rear end and thereby depresses the forward end of the dog, so as to cause it to enter and remain 'within the mandrel. The rear end of the dog 91 is curved upward and projects through the rear end of the slot 90 above the mandrel.
Then the rotation of the mandrel-carrier 61 has brought a mandrel, 74, into proper position diagonally in front of the die-block 29, the rear end of the dog 91 will have been depressed against the spring 92 by a curved lever, 93, pivoted in the bracket 42 and operated through a link, 94, that connects with the lever 43 for actuating the cutter-head. The forward end of the dog 91 is thus raised out of the slot 90 and above the mandrel. The movements of the machine are so timed that at this moment, while the dog 91 remains elevated, the forward edge of the incomplete paper blank, Fig. 16, at the corner nearest the outer end of the mandrel, is passed by the action of the feed-rollers 18 beneath the raised dog 91, and at the next downward stroke of the cutter-headthe knife 51 severs the blank 57 from the paper'strip, as before explained. Simultaneously with the descent of the cutterhead the lever 93 releases the dog 91, which is immediately acted upon by the spring 92, so as to cause it to press the forward edge of the blank 57 into the slotted mandrel and hold it securely. The descent of the cutter-head carries with it a presser-foot, 95, attached to the knife 51, and this presser-foot forces the rear edge of the paper blank 57 into contact with a paste-roller, 96, which is supplied with a suitable adhesive substance, as hereinafter explained. The bevel-gear 81 now makes onethird of a turn-to the right and through the pinions 80 gives four revolutions to the mandrels, thereby winding the paper blanks thereon. At the same time the revolving mandrelcarrier 61 makes one-twelfth of a turn to the left, thereby bringing another mandrel diagonally in front of the die-block 29 to receive a blank, as before described. The movement of the carrier 61 and gear 81 in opposite directions continues in this manner, and the rotating mandrels, with attached blanks, are carried over and in contact with an adjustable spring-guide or lower presserarm, 97, provided with a hook-shaped end, 97", having a convex surface, against which the paper blanks are pressed in succession by the movements of the mandrels as they pass over said convex surface and beneath an upper presser-bar, 98, 7 whereby the paper blanks are kept closely wound on the mandrels until the paste or adhesive substance on their outer edges has dried. The upper presser-bar, 98, is approximately circular in form, as shown in Fig. 3, and extends nearly around the mandrel carrier. This presser-bar 98 is provided with radial arms 99, connected to a hub, 100, that rests loosely on the hub of the mandrel-carrier, so as to be capable of yielding slightly; but in order to prevent the bar 98 from turning with the carrier a stop, 101, Fig. 2, is attached to the bracket 42, in line with one of the radial arms. As the revolution of the mandrel-carriercontinues, the mandrels and blanks wound thereon are made to pass over a sponge or a other absorbent substance, 102, saturated with melted wax or parafline, with which the tips of the mouth-pieces are thus coated to prevent them from sticking to the lips of the cigarette-smoker. The sponge 102 is placed in a receptacle, 103, having a perforatedpartition, 104, that separates the sponge from the wax or parafline, which can be kept in a melted condition by means of a gas-jet, 105, connected with a supply-pipe, 106; or a lamp may be used, if preferred. When one revolution of the mandrel 61 is about two-thirds completed, the mandrel that was first supplied with a paper blank arrives opposite a receiver or pull-off that comprises two telescopic tubular parts, 108 and 109,- Fig. 12, one of which (indicated by 109) is firmly secured to a horizontal slide, 110, movable on a dovetailed or ribbed guideway, 111, which is formed on or supported by an angle-block, 112, adjustable on the machine-table 1 by means of slots 113 and set-screws 114, Fig. 11, so as to enable the pull-off to be adjusted to or from the mandrel-carrier. Tothe slidel 10 is attached a horizontal arm, 115, which passes through aslot, 116, in the guideway'lll and IIO connects with a lever, 117, as shown in Fig. 11. The lever 117 is attached at one end to the rigid arm 115 and at the other end to a lever, 118, mounted securely on the upper end of a vertical spindle, 119, Figs. 2 and 4, which is provided at its lower end with a rigid arm, 120, that connects with the upper arm of a bell-crank, 121, fulcrumed on the fixed rod 40 and having 011 its lower arm a friction-pulley, 122, Fig. 5, that engages a cam-race, 123, in a cam-disk, 124, Fig. 4, on the cam-shaft 10, thus providing means for actuating the pulloff from said cam-shaft.
The tube 108, composing the inner end of the pull-oil or receiver, is of large diameter and less length than the tube 109, which constitutes the outer end of said device. In each side of the tube 108, at its inner end, is a rectangular opening, 125, to afford a clearance for the mandrels, as will be presently explained. This tube 108 also has an openended slot, 126, in its top, a spring, 127, that covers said slot and projects beyond the inner end of the tube, and an internal annular shoulder,128, cut away centrally on each side at 129, as shown in Fig. 12, to permit the passage of spring-hooks 130 on each side of the other tube. To the outer end of the tube 108 is attached a forwardly-projecting guide-rod, 131, for a spiral spring, 132, that is supported thereon. The tube 109 is formed at its inner end with a flange or collar, 133, to engage the annular shoulder 128 in the tube 108. On its top it is provided with a stop or hearing, 134, for the outer end of the spiral spring 132,and at its bottom it has a longitudinal slot, 135, which corresponds with a similar slot, 135, in the bottom of the tube 108 for passage of an ejector rod or wire, 136, that is arranged to remove the finished tubes from the pull-off or receiver.
It will be seen that the tube 108 is supported loosely on the tube 109, and that the rod 131, spiral spring 132, and step 134 together form a yielding connection between these two tubes comprising the pull-off and receiver for the finished mouthpieces. This pull-off or receiver is reciprocated along the guideway 111 by means of the operating devices connecting with the cam-shaft 10, as already explained.
The various parts of the machine are so arranged and timed that the pull-off, which has moved outward along the guideway 111 in removing a finished mouth piece or tube from a mandrel, will return in season to inclose the next mandrel and its attached mouthpiece,
which have meanwhile been brought into proper position by the revolving mandrel-carrier. As the tubular portion 108 of the pulloff moves inward around the mandrel 74 and into contact with the collar 73, the spring 127 will bear 011 the rear upwardly-turned end of the dog or latch 91, depressing the same against the action of the spring 92 and causing the forward end of the dog to rise slightly in the mandrel-slot 90, thereby disengaging the dog from the inwardly-turned lip or cornor of the paper blank at the tip of the mouth-piece. lVhen the inner end of the tube 108 comes in contact with the collar 73, its movement is of course arrested; but the tube 109, carried by the slide 110, continues to move inward within the tube 108 until the spring hooks or catches 130 pass behind and engage the enlarged end of the mouth-piece. In this inward movement of the tube 109 the spiral spring 132 is compressed, and as the said tube 109 recedes, carrying with it the mouthpiece or cigarette-holder, the tension of this spring 132 exerts a pressure on the tube 108 to hold it in place with its spring 127 bearing 011 the rear end of the dog 91 until the cigarette-holder has been nearly withdrawn from the mandrel. By this time the collar 133 will be in contact with the shoulder 128, and both tubes 108 and 109 thus connected will move off together and Withdraw the cigarette-holder completely from the mandrel. The dog 91, relieved from the pressure of the spring 127, returns to its normal position under the action of the spring 92, and the mandrel-carrier 61 makes a partial revolution to bring another mandrel into position for the action of the pull-oil. The openings 125 in the sides of the tube 108 afford a clearance for the mandrel, so as to prevent any liability of interference between the pull-oil": and rotary mandrel-carrier in their respective movement-s. The slot 120 in the top of the tube 108 enables the rear upwardly-proj ectin g end of the dog 91 to come under the action of the spring 127, and the notches or recesses 129 in the sides of the annular shoulder 128 permit the hooks 130 to carry the removed mouthpiece well into the pull-off or receiver.
Each successive cigarette holder or mouthpiece removed by the pull-otf is telescoped in said pull-off or receiver with the holder or mouth-pieces previously removed, as shown in Figs. 10 and 11, until the tube 109 contains, say, five telescoped or nested mouth-pieces After the pull-off has thus received, say, five mouth-pieces or holders, and as it moves inward to take off another, the ejector-rod 130 is moved upward into the slot 135 at the rear end of the line of telescoped mouth-pieces, thereby obstructing their return with the tube 109 and causing them to drop from the outer end of said tube into any suitable receptacle.
The ejector 130 is carried by a lever, 137, that is pivoted to the table 1 and depressed by a spring, 138, attached to the table, as shown in Figs. 2 and On the under side of the ejector-lever 137 is a projection, 139, that rests on a cam, 140, carried by a shaft, 141, mounted in bearings 142 beneath the ma chine-table. The shaft 141 is rotated through a sprocket-gear, 143, driven by a chain belt, 144, from a sprocket-gear, 145, mounted 011 a short shaft, 146, beneath the machine-frame. This short shaft 140 is driven through a spurgear, 147, from a pinion, 148, on the main camshaft 10, and thereby actuates the cam 140 through the intermediate mechanism to cause it to elevate the ejector-rod 136 at proper intervals. To tighten the belt 144 and hold it in position, a flanged idler, 149, is provided, as usual.
The paste-roller 96 is journaled in a hinged bearing, 150, Fig. 9, so as to enable it to have a yielding contact with the supply-roller 151,
which is mounted onone end of the shaft 141 at the side of the machine-table and beneath the paste-roller. This supply-roller 151 revolves in a suitable receptacle, 152, containing paste or other adhesive material, and a ily understood and need not be further eX-- plained.
The machine is automatic in all its operations, and is capable of rapidly producing large quantities of tapering tubes or holders, such as shown in Fig. 18, completely finished and ready for the trade.
We do not herein claim the combination, with a rotary mandrel having a longitudinal groove, of a swinging spring gripping-finger pivoted intermediate its ends in said groove, a swinging lever for acting on the tail end of the finger to swing the latter, and a rotary cam for actuating the lever, as such is claimed in an application filed by Robert \V. Thurman March 28, 1887, Serial No. 232,624.
