3 Claims. (Cl. 131-70) The present invention relates to a cigarette making machine and more particularly to a manually operated cigarette making machine of the portable type.
The cigarette making machine, according to the invention, is of the type using cigarette tubes and in which the tobacco is compacted and pushed within the paper cigarette tube by a single rotary motion.
The general object of the present inventionis the provision of a cigarette making machine of the type above mentioned which is of improved and simplified construction.
Yet another important object of the present invention is the provision of a machine of the character described in which the tobacco lis compacted and then slightly released in order to allow its easy ejection into the cigarette tube.
Yet another important object of the present invention is the provision of a machine of the character described in which the tobacco receiving and compacting chamber is made integral with the top plate of the machine thereby effecting a great simplification in the construction thereof.
Still another important object of the present invention is the provision in a machine of the above mentioned type of a cigarette tube retaining leverwhich maintains said tube on the machine during the tobacco ejecting operation and then automatically releases the tube at the end of said operation.
The foregoing and other important objects of the invention will become more apparent during the following disclosure and by referring to the drawings in which Figure l is a perspective view of the cigarette making machine according to the invention.
Figure 2 is a cross-section of the same. n
Figure 3 is a plan section along line 3 3 of Figure 2.
Figures 4, and 6 are similar plan sections showing different stages of operation of the machine; and
Figure 7 is a fractional cross-section along line 7 7 of Figure 3.
Referring now more particularly to the drawings in which like reference characters indicate like elements throughout, the letter A indicates a base made of wood,`
plastic or other suitable material enclosing and'supporting a casing generally indicated by B and preferably made of sheet metal. Said casing B comprises a top 1, side walls 2 and a back wall 3. The front edge portion of the top 1 is bent back in a semi-circular bend 4 to form an extension lying underneath the top 1 and forming the bottom Sand sides 5 of a tobacco receiving chamber 6.
The base A has an upwardly extending panel 7 to close the front of the casing B and Amerging at its upper edge with the bend 4.
The top 1 is provided with an aperture 8, in register with the tobacco receiving chamber 6, through which aperture the tobacco is fed.
A tobacco compacting member 9, in the form of a plate having a concave front edge 10 is movable within the chamber 6 from a back retracted position clearing the aperture S, to a forward tobacco compacting position closf ing through the top 1 of the casing B. A handle 23 se 'ice ing the aperture 8 and leaving at the front of the chamber 6 a cylindrical space defined by the semi-circular bend 4 of the top 1 and the concave front edge 10 of said compacting member 9. A plunger 11 is movable through said cylindrical space across said chamber 6 from a retracted position, as shown in Figure 4 or 5, to a fully engaging position as shown in Figure 6. In the latter position, the plunger 11 engages the tobacco ejecting nipple 12 which is in communication with the tobacco receiving chamber 6 and is secured to a side wall 2 of the casing B.
The plunger 11 is guided in its movements and supported by a semi-circular trough 13 in alignment with the tobacco ejecting nipple 12 and withrthe cylindrical space of chamber 6 which is defined when the tobacco compacting member 9 is in forward position. This trough 13 is made in a manner similar to the bottom 5 of the chamber 6 by bending and extending the front edge of the top 1 of the casing B.
The tobacco compacting member 9 is maintained parallel with itself during its forward and backward movements and is actuated by means of two toggle joints, the link 14 of each toggle joint being pivoted at 15 to said tobacco compacting member 9 and the other link 14 of each toggle joint being pivoted to the top l-by means of bolts 17. The links 14, 14 of one toggle joint are kept parallel to the links 14, 14 of the other joint respectively at all times byV means of a transverse link 18 connecting the knee pivot 16 of each toggle joint and having an extension 19 provided with a downwardly extending stud 20.
The stud 20 on the link 18 abuts the outer edge' of a cam 21 secured to an Vaxle 22 rotatably mounted and passcured to the upper end of the axle 22 serves to Vrotate the same in a reciprocal movement.
An arm 24 is freely pivoted on the axle 22 and is` connected at its outer .end to the plunger 11 by meansof a link 25pivotally secured to the arm 24 at 26 and to an extension 27 of the plunger 11 at 28. A coil spring 29 is attached to the arm 24 at one end and to the casing B at the other end to urge the arm 24 towards the right and consequently the plunger 11 into retracted position. The'v arm 24 isv actuated through the axle 22 and cam 21 by abutting. downwardly extending pins 30 and`31 securedr 'The cam 21 has an outer cam edge deinedby a recess 32 extending inwardly towards the axle 22 and insubstantial alignment withV a radius of said axle 22, said recess 32 having a curved side 47 merging at the point 48 with a circular portion 33 coaxial with the axle 22. The other side of the recess 32 is defined by the curved edge 50 of the finger 49, said edge 50 extending to a point 51 spaced from and substantially opposite the point 48 where the edge 47 and the portion 33 are merging'. Rotation of the cam 21 `will impart to the stud 20 and consequently to the transverse link V18 the required movements that will be described presently.
Figure 4 shows the machine in inoperated position,` ready to receive tobacco through the opening 8,`the tobacco compacting member 9 and the plunger 11 being in fully retracted'position. In the position shown in Figure 4, it is seen that the stud 20 engages the recess'32 `of Vthe V camv 21 and that the arm 24 abuts the pin 31 of said cam 21. Clockwise rotation of the axis 22 through the handle" 23 will cause displacement of the link 1S 'towardsthe left and therefore `forward movement of the tobacco compactf ing member 9 to its front limit position as shown in FigureA1 further clockwise rotation of the axle 22, the link 18 is further displaced to the right thereby causing a slight backward movement of the tobacco compacting member 9 in order to decrease the pressure exerted on the tobacco and to allow entrance of the plunger 11 into the chamber 6 as shown inv Figure 3. 1n the position shown in Figure 3, the stud 20v rides on the circular edge portion 33 of the cam 21 andthe end 52 of the link 18 abuts against the wall 2 of the casing B whereby axial displacement of the link 18 is completely prevented during the movement of the plunger 11.
This plunger 11 is actuated when the arm 24 comes in contact with the pin 30 on the cam 21.
The tobacco within the chamber 6 is ejected through the nipple 12 intov the cigarette tube held on said nipple 12 until the plunger 11 has reached its left limit position as shown in Figure 6. l
Upon return or anticlockwise rotation of the axle 22, the above described movements of the various elements are repeated in reverse order, according to the consecutive positions shown in Figures 6, 3, and 4.
It will be noted that the spring 29 is necessary for urging the plunger 11 into fully retracted position in order to permit the tobacco compacting member 9 to take its front limit position, as shown in Figure 5, during anticlockwise rotation of the cam 21, because the pin 31 abuts the arm 24 only after said front limit position of the tobacco compacting member 9 is reached.
As shown in Figures 4 and 5, the tobacco compacting member 9 is caused to move backward to its rear limit position when the stud 20 engages the recess 32 in cam 21 in order to displace the link 18 towards the right.
The cigarette tube is heldon the nipple 12 by means of a cigarette tube retaining lever 34 pivoted on the bottom 5 of the tobacco receiving chamber 6 by means of a shoulder pin 35. The lever 34 projects from the side wall 2 adjacent the nipple 12 and mounts a gripping pin 36 adapted to contact the cigarette tube on the nipple 12. Said lever 34 is urged in contact with the nipple 12 by means of a coil spring 37 attached thereto and to the front portion of the casing 1.
The tube retaining lever 34 is provided with an extension38-bent upwardly at its free end to form an abutment 39 adapted to come in contact with a link 14 as shown in Figure 4 in order to cause the tube retaining lever 34 to assume a releasing position at the starting position of the machine whereby the cigarette tube may be inserted on the nipple 12. As soon as the machine is started said link 14 disengages the abutment 39 whereby the lever 34 assumes its cigarette tube retaining position as shown in Figure 5.
Near the end ofA the operation when the tobacco has been nearly completely ejected within the cigarette tube, that is in the positionA shown inA Figure 6, the arm 24 comes in contact with a second extension 40 of the retaining lever 34 to pivot the latter into its cigarette tube releasing position, whereby the completed cigarette is allowed to disengage the nipple 12.
The necessary clearance for the movements of the various parts of the machine according to the invention is obtained by disposing said parts at different levels as shown in Figure 7. For that purpose, the axle 22 is provided with spacer collars 41, 42 and 43, the bolts 17 with a collar 44 and the'pivot 28 with a spacing sleeve 4S.
The camv 21 and thearm 24- may be easily disrnounted by unscrewing the nut 46 at the lower end of the axle 22.
While a preferred embodiment according to the present inventionhas been illustrated and described it is understoodthat'various modifications may be resorted to without departing from the spirit and scope of the appended claims'.
