PROCESS AND APPARATUS FOR THE MANUFACTURE OF CIGARETTES WITH A SHORT MOUTHPIECE OF WADDING, CREPE PAPER 08 THE LIKE Filed Feb 16, 1933 mve NT}! 'W, MuZZer Patented June 18, 1935 UNITED" STATES PATENT OFFICE Carl Wilhelm Miiller, Dresden-Wetsui- Hirsch, Germany Application February 16, 1933, Serial No. 657,140 In Germany March 8, 1932 12 Claims.

This invention relates to a process and apparatus for the manufacture of cigarettes with a short mouthpiece of wadding, crepe paper or the like. In order to economize tobacco in the manu- 5 facture of cigarettes it is suitable to provide the cigarettes at the mouthpiece end with a short filling of wadding, crepe paper or the like. Such cigarettes, like the known mouthpiece cigarettes with a long cardboard mouthpiece, are manufactured by filling. In this connection, there is the disadvantage that the shells with the short mouthpiece of wadding or paper can only be removed with difiiculty from the filling revolver in order to be pushed on the filling spoon, for the reason that the mouthpiece is extremely short relative to the portion of tobacco.

The present invention remedies this disadvantage by the fact that the manufacture of the shells with the mouthpiece, and also the filling, are eachocarried out in the known manner by means of so-called shell spoons or filling spoons, but the two spoons are so disposed relative to each other that the shells provided with the mouthpiece are transferred from the shell spoon directly to the filling spoon, that is to say, it is no longer necessary to remove the shells provided with a mouthpiece from the shell machine and to transfer them into a separate filling machine. The shell spoon and filling spoon execute feed movements in opposite directions such that in one position they are situated opposite the continuous length of shell and the tobacco rod respectively, and in the other position they are situated opposite each other in the same direction.

An embodiment of the invention is shown diagrammatically by way of example in the accompanying drawing wherein:-

Figure 1 is a plan view of one embodiment,

Figure 1a is a side view of a part of Figure 1,

Figure 1b is a side view of a spoon,

Figure 1c is a plan view of Figure 1!),

Figure 1d is a side view of Figure 1b,

Figure 16 is a side view of another spoon arranged within the disc carrying it,

Figure 1 is a plan view of Figure 1e,

Figure 2 is a side view of the discs holding the spoons.

In the drawing, a is the paper strip supplied to the machine which is formed in the usual manner into a paper shell which moves towards the shell spoon. In the example shown, a number, for example four, of such shell spoons b are provided, being mounted in common on one disc 0. The disc is mounted on a spindle d and is rotated stepwise. For this purpose th spindle d is provided with a bevel gear d engaging a second bevel gear at on a spindle d. This spindle is'connected by means of a pair of bevel gears 11* with a spindle d at one end of which 5 there is arranged a disc d having pins or projections d projecting into the path of a rotating cam d". The cam is carried by a spindle d intermittently driven by any means not shown in the drawing. Figure 1 shows the instant at which the forwardly moved paper shell has been pushed on to the lowermost spoon. The necessary length of shell is now cut oil by the pair of knives 6. At the same time, a strip, for example a strip of wadding I, for making the mouthpiece is fed from the opposite side. This may be done by means of a conveying device a. The strip of wadding is inserted into the spoon itself and the necessary piece is cut of! by a pair of knives h. Thus, a severedlength of the paper shell is placed upon or around the spoon, while a corresponding piece of wadding is situated inside the spoon. As soon as this has taken place, the disc. 0 is fed further by one quarter of a revolution. A fresh length of the paper shell is pushed on to'the next spoon to and a fresh piece of the strip of wadding is inserted into it. Oppositely directed to the shell spoons, there are provided a number of filling spoons i mounted on a disk It. The latter in its .80 turn is mounted in the machine frame on a spindle k and the disc k makes stepwise revolutions in the same time sequence as the disc 0. For this purpose the spindle k is connected with the spindle k by means of bevel gears 16 and the spindle k is driven by the spindle d by means of a pair of bevel gears 7:. During each pause of the two discs, a shell spoon b and a filling spoon i are situated opposite each other. Figure 2 shows the position of the two discs rela- 40 tively to each other. The inwardly directed spoons lie in the same line. As soon as the spoon b with the shell lying upon it has arrived in front of the filling spoon, a plunger m moves towards it. The said plunger m engages the shell spoon internally, and has a lug m which passes through a slot b provided in the spoon and the disc 0. Consequently, the front face of the plunger m bears against the wadding mouthpiece, while the lug m bears against the shell, so that on the plunger m being moved forward by the crank n and the lever 11 actuated by the said crank, the shell together with the mouthpiece is pushed off the shell spoon and on to the filling spoon. The shell thus pushed on to the fillingspooniisshowninl'ig. 1 ofthedrawing at a The crank n isprovided on a spindle n driven by the spindle d by means of a belt 1: running over thepulleys n and d" respectively. The introduction of the tobacco rod is now ef fectedon th'e fillin'g "The tobacco rod is. made in the rod forming device indicated in thedrawingat 0, and is fed to the disc I: from the rear thereof. It is inserted into a short tube 9 and as soon as the necessary length-of tobacco rod has been inserted through the spoon into the short tube, the rod is severed by the knife q.

During the insertion of the rod into the spoon and hence into the shell, the latter must be held on the spoon by a known device because otherwise it would be pushed off the spoon, due to the friction of the tobacco against the shell during insertion. This may be efi'ected for example by means of the head r of a slide rod 1' bearing against the rear end-of the cigarette during insertion of the tobacco. The slide rod r is guided in a suitable manner in the machine frame and its free rear end is hinged to a lever s which is pivoted about a point s in the machine frame, and which has its other end engaging a groove t of a grooved drum 1! by means of a roller or a pin. The groove t is such that the lever s and hence also the slide rod 1 are given a reciprocating movement. The drum t is mounted on a spindle t iournalled in the machine frame and driven by the spindle n by means of an intermediate spindle t and the bevel gears t and t respectively. A lever v is rotatably mounted in a small support it on the slide rod r. The lever rocks about the pin u mounted in the support u, and its front end carries a hook-like member to, while the rear end is under the control of a cam a: mounted on a shaft This shaft is connected, with the spindle t by means of a pair of screw gears 2 As soon-as the rod made in the rod forming device 0 has been pushed forward by the guiding and pressing rolls 1! and g and the necessary length has been cut oil, the lever 12 is rocked by the cam a: so that the hook to is brought in front of the tobacco filling which it inserts into the shell through the action of the cam 1:. During its further movement, the hook w then passes through the slit i provided in the spoon i and disc It draws the shell, ready filled and provided 'with the mouthpiece, of! the spoon while the rod 1' is restricted. The cigarette is then finished, and it falls on the spoon and may be conveyed away in the usual manner.

Of course, the arrangement may be otherwise constructionally designed. For instance, the devices for actuating the individual mechanisms,

the device for forming the rod, for forming the shell, the cut-ofl devices and so forth, may be constructed in any other way, and in particular any known kind of such devices may be employed 'for the purpose of the present invention. Of

- course, the apparatus may also be constructed with only one single shell spoon, and a single filling spoon, or spoons, reciprocating in one plane may be employed instead of the spoons rotating stepwise.
