SPECIFICATION forming part of Letters Patent No. 546,404, dated September 17, 1895.

Application filed October 26, 1894. Serial No. 527,076 (No model.) Patentedin France August 24, 1894, No. 24,951.

To all whom it may concern.-

Be it known that I, CHARLES ALFRED MAR- CHAL, a citizen of the Republic of France, and a resident of Paris, France, have invented certain new and useful Improvements in Machines for Making Paper Cigarette-Tubes, (for which I have obtained Letters Patent in France, No. 24,951, dated August 24, 1894: of which the following is a specification.

This invention relates to machines known as Decoupls -and'others for manufacturing paper cigarette-tubes without adhesive material-that is tosay, for manufacturing tubes and cigarettes which are closed by interlocking the edges of the paper or by any other means that do'not require the use of adhesive material and are twisted at an end thereof.

These improvements consist, first, in a novel arrangement of mechanism which can be easily adapted to existing machines for closing or twisting one end of the paper tube before the latter is out 01f to the required length, the object being to prevent the escape of the tobacco from the tube and especially of the picadura tobacco employed in the manufacture of what are known as Havana cigarettes. This arrangement of mechanism consists of two thin blades placed opposite to one another and perpendicularly to the longitudinal axis of the spindle, and which in turning approach one another when the tube is finished in order to twist its end, which extends six or eight millimeters beyond the end of the tube-forming spindle, and thereby to form with this projecting part a sort/of bottom, which retains the tobacco in the tube. In open-end non-pasted cigarette-tubes as at present constructed there is nothing to prevent the escape of the tobacco from the tubes, especially when this tobacco is of a granular nature like that used in Havana cigarettes, or when it is dry like that used in ordinary cigarettes, such as Oaporal, the.

In its application to known machines for manufacturing cigarettes without adhesive material on what is known as the Decoupl system this new mechanism requires to be supplemented by another piece of mechanism the object of which is to take the finished tube that is to say, the tube cut to length and twisted at one end-and to turn it around, so as to present it with its open end opposite the filling mechanism. The turning mechanism forms the second part of the improvements. This supplementary mechanism is not required, however, when the filling mechanism, instead of being placed at the other side of the driving-gear, as in the aforesaid Decoupl machines, is placed at the side of the driving-gear over the cam actuating the filling spindle. In such an arrangement the twisted end is presented in a favorable position relatively to the filling mechanism.

In the annexed drawings, Figure 1 Han elevation of part of an improved Decoupl machine for manufacturing non-pasted cigarette-tubes, showing my improvements applied thereto. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a transverse section taken on line 1 2 of Fig. 1, showing the arrangement employed for turning around end for end the non-pasted tube after one of its ends has been closed or twisted. Figs. 4 and 5 are respectively an elevation and a vertical section of the mechanism for folding or twisting the end of the paper tube. Fig. 6 is a detail view, to a larger scale, of the blades of the twisting mechanism. Fig. 6 shows part of the mechanism for actuating the twisting-blades shown in Fig. 7. Fig. 7 is an elevation of the scissors for cutting oft the tubes. Fig. 8 and 9 are respectively an elevation and a plan view of thesupport for the tube-forming spindle and of the spindle itself, upon which spindle the tubes are made and closed. Fig. 10 represents the end of a finished tube, showing an end and side view of the same.

In the improved machine a designates the ordinary table, on which is fixed an extension a, which carries four vertical supports 22 c d e. The first support his cast in one with a fork 1), between the branches of which is arranged a roller 5', which serves as a guide for the paper as, which unwinds from abobbin 5c, mounted on the wheel or core 0', fixed on a shaft 0 the ends of which rest in hearings on the two branches of the support 0. The shaft 0 can turn freely in its bearingsybutit is subjected to the action of two blade-springs c ICO the object of which is to increase the friction developed during the rotation of the shaft 0 and to act as a brake.

The tension of the paper is obtained by a guideroller c, which rests upon it, and is mounted between the ends of two parallel balance-levers 0, carried on the support 0, by screws c, on which they are free to oscillate. These levers c are also furnished with connterweights 0 which can be adjusted on them so as to balance the roller 0 more orless, and thereby to permit as exact an adjustment as possible of the tension of the paper so. I

The support I) contains the rod or stem which carries the printing-stamp and which is actuated by a leverarm b fixed on the end of a rock-shaft Z)", operated bya lever b the end of which is provided with a friction roller engaging in the groove of a cam b mounted on the intermediate shaft f, placed above the table a, as in the ordinary Decoupl machines.

The support 0 is provided with an opening at its lower part to allow of the passage through it of the long boss d of the support (1. rod d which carries the inking-pad d, which at each revolution of the machine comes in contact with the printing-stamp carried by the support I).

As in the Decoupl or other similar machine after a tube has been made, the printingstamp operated by the lever b prints the required mark under the paper to, after which the said stamp is inked by coming in contact with the pad 61 carried by the rod (1 The support d carries at its upper end an L-shaped piece (1, the vertical branch of which allows the passage through it of the tube-forming spindle provided at its heel with an upright g, (see Figs. 8 and 9,) which engages in a slot (1 of the support (1 where it is suspended by a terminal button or head 9 This slot opens into a wider opening d in the horizontal branch of the L-shaped piece (Z through which opening the head 9 of the upright 9' can pass. A screw (1 furnished with a lock-nut (Z and screwed through the horizontal part of the support d, enters-by its pendent end into a hole in the spindle g and prevents any longitudinal displacement of the latter. To take out the tube-forming spindle g, the screw (1 is unscrewed sufficiently and the spindle is slid back so as to bring the head opposite the opening (1 of the horizontal branch of the L-shaped piece (1. The head g is then passed through this opening and the spindle g is then easily removed.

The spindle 9 beyond the milled roller G for creasing or gotfering the longitudinal joint of the paper tube is prolonged two or three centimeters, as shown in Figs. 8 and 9, in order to support the manufactured tube during the operation of folding or twisting In the interiorof this long boss slides the its end. The dotted line shows the tube before it has been twisted and after the scissors have cut off the preceding tube.

The purpose of the construction represented in Figs. 8 and 9 is to regulate the pressure of the spindle g andof its crimping or goffering roller against the larger crimping or goffering roller above it, which serve, also, to transport the tube and at the same time to afford a simple and easy means of removing the spindle Q When required. The spindle g] hangs by the head 9 in the narrow slot ti", and the screw al acts upon the rear end of the spindle g to press the front end more or less firmly against the upper creasing or gotfering roller.

The construction of the scissors for cutting off the paper tubes is as follows: The branch of one of the blades, instead of being curved, has an extension h, terminating in a stud 72., standing at right angles to it, and upon which is hooked one end of a spring 7L2, the other end of which is attached to the other branch of the scissors, and which spring constantly tends to draw the two blades 7L3 together, the opening and closing of the said blades depending on a cam 7V in the usual well-known manner. This construction of the scissors allows of the employment of a long spring 71 for closing the blades together, which gives greater regularity and smoothness in the cutting off of the paper tube.

The folding or twisting mechanism is placed at the end of the prolongation of the tubespindle g. It is actuated by agrooved pulley i on the shaft f, which communicates motion by a cord or strap 1" to another pulley 2' cast with or connected to a toothed wheel 7;, which gears with the pinion 7c. The pinion 7c" is fixed on a socket m, (see Fig. 5,) on which is also secured a sleeve having a circumferential groove. This sleeve k is free to move longitudinally on the socket 7%, while the latter is rotated by the pinion 7t. For that purpose there are engaged in the groove of the sleeve 70 the ends of the branches of a fork k at one end of a lever oscillating on an axis 75, fixed to the table Ct. The end of the lever it opposite to the forked end is provided with a friction-roller k which takes into the groove of a cam 2' cast with or connected to the pulley 2", and which cam imparts to the forked lever 76 the required oscillatory movements. The sleeve 70 can slide, as before explained, on the socket m. Two grooves m are formed diametrically opposite to each other, in which are placed two pieces m the free end of each of which is connected to a metallic blade m which moves in an opcn ing m, made perpendicularly to the axis of the spindle g in the thickness of the end of the socket m. The acting parts of the blades m are cut out to a curvilinear shape, as shown clearly in Fig. 6, in such manner that as these blades approach one another they IIO seize the paper tube to be closed centrally by their projecting parts in.

The pieces m which impart alternating rectilinear radial movements to the blades m are raised out of the grooves of the socket in by the sleeve as each of these pieces is provided with a projecting heel (see Fig. 6) and is pivotal on a pin m sunk in the socket 022, so that as the sleeve 70 1s moved backward on the sprocketm it turns the pieces in on the said pin m until the upper edges of the said heel parts of such pieces come level with the periphery of the socket 721.

The tubespindle g, above referred to, enters the central opening of the socket in and stops about half a millimeter short of the blades m All this twisting or folding mechanism is mounted on an intermediate support 1i,fixed on the principal support e.

When the paper tube is formed-that is to say, when the edges are interlocked or simply placed one over the other and pressed down or creased by the well-known devices G G, Figs. 1, 2, and 8it extends about seven millimeters beyond the spindle g, Figs. 8 and 9. The cam & then acts on the forked lever I0 and the sleeve 71: slides on the socket m while it continues to turn therewith, the said socket receiving its rotatory motion from the pinion in, which gears with the toothed wheel 70, driven by the grooved pulley 2'. During the longitudinal movement of the sleeve k the pieces m bend and approach each other and move the blades m which in turning twist the paper forming the end of the tube and\ press it down when they have quite come together, so as to form a twisted bottom normal to the longitudinal axis of the tube and presenting somewhat the external appearance shown in Fig. 10.

As above stated, the folding mechanism is applicable to existing machines for manufacturing non-pasted cigarette-tubes with their longitudinal edges interlocked or not, as the case may be, the interlocking being either external orinternal; but when applied to existing machines for manufacturing non-pasted tubes on the Decouple system the twisted end is presented to any suitable filling mechanism, as represented at A, for filling the cigarcite. It is therefore necessary to add other devices which impart a half-turn to the tube, in order that the open end of the latter may be presented to the double filling-funnel A in front of the ramming-spindle of the filling device A. Various arrangements of mechanism may be employed for this purpose. 1 prefer, however, that shown in Figs. 1, 2, and 3, but without limiting myself to the employment of that particular arrangement. This arrangement comprises a cam p, mounted on the lower intermediate shaft 0 of the machine, and each side of which cam is provided with a groove. On the front of the table a is a vertical cylindrical rod 7, capable of being moved up and down and furnished with two collars r, between which take the branches of a fork s. This fork s forms one end of a lover s, free to oscillate on a fixed axis .9 and the other end of which lever is furnished with a friction-roller which engages in a groove 5 of the cam 19. In the other groove i of the cam 10 takes a friction-roller mounted at the end of a horizontally-sliding rod "6, carrying a rack t, which gears with a pinion r on the rod 0'. This pinion r is of a height suffieient to allow the rod r to move up and down vertically to a certain extent without the pinion r coming out of gear with the rack 25.

The rod r terminates at its upper end in a fork W, the two branches of which form a V- shaped notch. The rod r is placed in the center line of the tube-transporting mechanism y 1 used in the well-known Decoupl machine, that is to say, between the sides of the movable carriage.

When a paper tube arrives over the fork r upon the transporting mechanism 3/ "y, the cam 1) acts on the lever s and raises the rod 7', and the tube represented in the drawings J by dotted lines is taken by the fork r", is raised thereby, and is disengaged from the carriage on which it has been resting. Then the rack if, actuated by the cam p, turns the pinion T and thereby the rod 7 and the paper tuberesting on it, half a revolutiomwhich causes the tube to be presented with its open end toward the rammingspindle. Finally the rod r descends and returns the tube onto the transporting-carriage, whence it is conducted by the tube-pusher 1),Fig. 2, into the double funnel A between the pinchers, which hold it While being filled in the usual well-known manner from the filling device A.
