CIGARETTE MAKrNG MACHINE Filed June 4, 1952 3 Sheets-Sheet 5 lnven kan United States Patent O CIGARETTE MAKING MACHINE Karl Kastner, Montreal, Quebec, Canada Application June 4, 1952, Serial No. 291,700 8 Claims. (Cl. ISI- 70) The present invention relates to a cigarette making machine and more particularly to a cigarette making machine of the portable or domestic type.

In a known type of manually operated cigarette making machine, the tobacco is compacted into a tobacco receiving chamber by means of a movable compacting member and the tobacco is then ejected into a cigarette paper tube by means of a plunger forcing the tobacco out of the restricted space defined by said chamber and said member, the latter being stationary during the tobacco ejection.

A disadvantage of such an arrangement lies in the fact that during ejection of the tobacco, a substantial friction is caused between the latter and the stationary walls of the chamber and the working face of the tobacco compacting member; therefore, a substantial force has to be exerted on the plunger.

Accordingly, the general object of the present invention is the provision of a cigarette making machine of the character described, in which the tobacco compacting member is movable along with the compacted tobacco in the direction of discharge of said tobacco whereby friction exerted during the tobacco ejection is substantially decreased.

Another important object of the present invention is the provision of a tobacco cigarette making machine of the character described in which the tobacco compacting member serves also as tobacco ejecting means.

Yet another important object of the present invention is the provision of a cigarette making machine of the character described in which the tobacco ejecting plunger is mounted on the tobacco compacting member and actuated thereby.

Still another important object of the present invention is the provision of a cigarette making machine of the rotary type which occupies a minimum of space, is of strong construction and will give eicient and prolonged serv1ce.

The foregoing and other important objects of the present invention will become more apparent during the following disclosure and by referring to the drawings in which:

Figure 1 is a perspective view of the cigarette making machine according to the invention;

Figure 2 is a cross-sectional elevation of the same along line 2-2 of Figure 3.

Figure 3 is a plan section taken along line 3--3 of Figure 2.

Figure 4 is a plan section along line 4-4 of Figure 2.

Figure 5 is a plan section along line 5-5 of Figure 2; and

Figures 6 and 7 are Figure 5, machine.

Referring now more particularly to the drawings in which like reference characters indicate like elements throughout, the machine, according to the invention, comprises a circular base 1 having an aperture 2 in the top wall 1' thereof and mounting a substantially circular casing 3 provided with an elongated slot 4 in the top ilat wall 5 thereof and with an elongated slot 6 in the bottom at wall 7 of said casing.

The slots 4 and 6 register with each other for receiving a vertical shaft 8 extending through the casing 3. The top wall 1 is provided with a tobacco lling aperture 9 registering with the interior chamber of the casing 3.

The interior side face of the casing 3 forms a groove plan sections similar to that of showing dlferent stages of operation of the 10 of semi-circular cross section as shown in Figure 2, and the said side face is longitudinally curved to form two opposed

semi-circular portions

11 and 12 joined by

straight portions

13 and 14 as shown in Figure 4.

A disc 15 is keyed on the shaft 8 and extends within the interior chamber of the casing 3. Said disc 15 is provided with a concave groove 16 at the periphery thereof which cooperates with the semi-circular groove 10 of the casing 3 to form a space of circular cross-section as shown at the left hand side of Figure 2 when the disc 15 is displaced to the left end of the slots 4 and 6 as shown in Figure 4.

A tobacco ejecting plunger 18 is pivotally secured at 19 to the peripheral portion of the disc 15 in order to eject the tobacco through the nipple 20 secured to a recessed side wall 3 of the casing 3 and in tangential alignment with the inside face of the circular wall portion 9 of said casing 3. The nipple 20 has a recess at its inner end for receiving bent portion 17 of the plunger 18.

A cam plate 21 is secured to the shaft 8 in sliding contact with the underface of the bottom wall 7 of the casing 3. Said cam plate 21 is provided with an elongated cam slot 22 receiving a roller 23 rotatively mounted on a pivot shaft 24 secured to the bottom wall 7 of the casing 3. The slot 22 has a portion 25 converging towards the shaft 8 at one end and merging with a substantially annular slot portion 26 at the other end.

Thus it will be understood that when the knob 27 secured to the top end of the shaft 8 is rotated in an anticlockwise direction from the starting position of the cam 21 shown in Figure 5, the roller 23, engaging the slot portion 25, will cause displacement of the: shaft 8 from the right hand side of the slots 4 and 6 to the left hand side thereof, to the position shown in Figure 3, whereby the disc 15 will close the tobacco filling aperture 9 and compact the tobacco within the

grooves

10 and 16 ahead of the plunger 18. Upon further anti-clockwise rotation of the knob 27, the shaft 8 will keep rotating in the left hand side ends of the slots 4 and 6, while the roller 23 is engaging the circular portion 26 of the slot 22, whereby the plunger 18 will eject the compacted tobacco through the nipple 20 into a cigarette tube. During the last mentioned rotational movement of the disc 15 there will be no friction between the tobacco and said disc, because said tobacco moves in unison with said disc. Friction will occur only along the stationary wall portion 11 of the casing 3.

The cigarette tube is held on the nipple 20 by means of a cigarette tube retaining arm 28 mounting a gripping pin 29 adapted to contact said nipple 20 and pivoted on the basel by means of a pivot 30 passing through the top thereof. A lever 31 extends within the base 1 and is secured to the pivot 30 and urged by means of a spring 32 to maintain the arm 28 into a cigarette tube retaining position. The coil spring 32 is attached to the lever 31 at one end and to the base 1 at the other end.

When the machine, according to the invention, is in starting position as shown in Figure 5, a pin 32 projecting downwardly from and secured to the cam member 21, abuts a side extension 33 of the lever 31 in order to maintain the arm 28 in cigarette tube releasing position.

In all the intermediate positions of the machine, such as the one shown in Figure 6, the pin 32 disengages the side extension 33 and the cigarette tube retaining arm 28 is urged into retaining position by the coil spring 32. At the end of the rotational movement of the cam plate 21, a second pin 34, projecting downwardly from and secured to the cam member 21, comes into contact with the outer end of the lever 31 to again release the cigarette tube retaining arm 28 as shown in Figure 7, whereby the completed cigarette, shown at C in Figure 1, is ejected from the nipple 20.

The machine may be dismounted by unscrewing the nut 35 at the threaded lower end of shaft 8.

While a preferred embodiment according to the present invention has been illustrated and described it is understood that various modifications may be resorted to witholut departing from the spirit and scope of the appended c aims.
