Description
10396~3 The present invention relates to a machine to be used by people to make their own cigarettes using tobacco and pre-formed hollow cigarette paper tubes.
Many individuals, for purposes principally of economy, and taste, wish to make their own cigarettes and by possessing a small hand-operated cigarette machine, one can by purchasing tobacco and a supply of hollow cigarette paper tubes which are readily available on the market make a supply of cigarettes at a cost less than the cost of an equivalent number of tailor-made cigarettes.
The present machine injects a compacted elongated cylin-drical wad of tobacco into a hollow cigarette paper tube which is held on a nipple provided on the machine, and while there are a number of machines of this general type presently available on the market, all known machines of this type have a substantial ; number of interfitting and moving parts and are fairly costly in manufacture and sale and require fairly constant maintenance.
The present invention overcomes the disadvantages pos-sessed by known machines by providing a machine which is simple and economical in construction and which has a minimum of moving parts and which produces cigarettes of high and constant quality with minimum upkeep.
~- Known machines usually have a single operating lever which acts both to compact a wad of tobacco against a spoon . member with further rotation of the single handle causing the spoon and wad of tobacco to be injected into a cigarette paper tube held on a nipple of the machine. Although a single lever may result in simpler operation, it does require a greater number of interworking and interfitting parts and malfunction of any of the component parts can result in the machine being inoper-ative. Additionally, such single lever machines are reasonably expensive in manufacture and production costs must, of course, be passed on to the user at the time of sale.
~103~6~3 The present invention provides a machine having a two lever operation, the first lever causing compaction of a wad of tobacco into an elongate cylindrical form, with movement of the second lever causing injection of the wad into a cigarette paper tube. The actions of the two levers are extremely simple and as indicated a minimum of working parts is required so that the machine is highly durable and requires a minimum of upkeep and maintenance.
Also machines presently available on the market cause compaction of the tobacco by movement of a tobacco compacting member which is moved by a toggle arm which works through a pair of parallel links and with known constructions this parallel linkage is necessary in order to maintain the tobacco compacting member in precise alignment in the tobacco compacting chamber so : that the wad of tobacco is correctly and exactly positioned in injection alignment with the positioned tube.
It has now been found that it is possible to move the tobacco compacting member by utilizing only one single link in a manner which herebefore was not considered possible if a satisfactory cigarette was to be obtained.
One embodiment of the invention contemplates molding - the combined tobacco compacting member from a NYLON (Registered trade mark for a synthetic polyamide composition) material which smoothly moves in a compartment which may be formed of acryonitrite-butadiene - styrene (ABS) or similar plastics material. Alter-natively, precise alignment may be accomplished according to a further embodiment by providing spaced and parallel grooves in the compacting member and guide projections on the casing which extend into the grooves whereby the compacting member is maintained in precise alignment during both its movement into and out of tobacco compacting position.

The present machine injects a compacted elongated cylin-drical wad of tobacco into a hollow cigarette paper tube which is held on a nipple provided on the machine, and while there are a number of machines of this general type presently available on the market, all known machines of this type have a substantial ; number of interfitting and moving parts and are fairly costly in manufacture and sale and require fairly constant maintenance.
The present invention overcomes the disadvantages pos-sessed by known machines by providing a machine which is simple and economical in construction and which has a minimum of moving parts and which produces cigarettes of high and constant quality with minimum upkeep.
~- Known machines usually have a single operating lever which acts both to compact a wad of tobacco against a spoon . member with further rotation of the single handle causing the spoon and wad of tobacco to be injected into a cigarette paper tube held on a nipple of the machine. Although a single lever may result in simpler operation, it does require a greater number of interworking and interfitting parts and malfunction of any of the component parts can result in the machine being inoper-ative. Additionally, such single lever machines are reasonably expensive in manufacture and production costs must, of course, be passed on to the user at the time of sale.
~103~6~3 The present invention provides a machine having a two lever operation, the first lever causing compaction of a wad of tobacco into an elongate cylindrical form, with movement of the second lever causing injection of the wad into a cigarette paper tube. The actions of the two levers are extremely simple and as indicated a minimum of working parts is required so that the machine is highly durable and requires a minimum of upkeep and maintenance.
Also machines presently available on the market cause compaction of the tobacco by movement of a tobacco compacting member which is moved by a toggle arm which works through a pair of parallel links and with known constructions this parallel linkage is necessary in order to maintain the tobacco compacting member in precise alignment in the tobacco compacting chamber so : that the wad of tobacco is correctly and exactly positioned in injection alignment with the positioned tube.
It has now been found that it is possible to move the tobacco compacting member by utilizing only one single link in a manner which herebefore was not considered possible if a satisfactory cigarette was to be obtained.
One embodiment of the invention contemplates molding - the combined tobacco compacting member from a NYLON (Registered trade mark for a synthetic polyamide composition) material which smoothly moves in a compartment which may be formed of acryonitrite-butadiene - styrene (ABS) or similar plastics material. Alter-natively, precise alignment may be accomplished according to a further embodiment by providing spaced and parallel grooves in the compacting member and guide projections on the casing which extend into the grooves whereby the compacting member is maintained in precise alignment during both its movement into and out of tobacco compacting position.
-2-' lU39603 It will be appreciated, however, that the guide projec-tions could be provided on the compacting member and the spaced and parallel grooves in the casing without departing from the scope of the concept.
Of course, when the grooves and guides are employed, any material such as metal can be used.
In the present arrangement, the main operating handle which is of bell-crank configuration is pivotally secured to the casing, and one end of the single link member is pivotally secured to the inner end of the main operating handle, with the other end of the link being pivotally secured to the compacting member.
When the three pivots are in alignment maximum tobacco compaction ; is achieved, and it has now been found that injection of a wad of compact~d tobacco is facilitated and a superior cigarette product obtained if the compaction member is withdrawn slightly from its maximum compaction position. The present invention provides this advantage by having the main operating handle move past the position of alignment of the three pivots and so after maximum , compaction there is some release of the compaction pressure which facilitates injection of the wad of tobacco. ;~

Figure 4 is a sectional view taken along line 4-4 of ; Figure 2;
- Figure 5 is a perspective view of a new injection spoon . and handle arrangement, and Figure 6 is a sectional view taken along line 6-6 of Figure 3.
Reference will now be specifically had to the accompanying drawings wherein like reference numerals refer to like parts.
~)396~3 The machine consists of a body or casing unit 2 of stylized configuration which has on its upper surface adjacent the front edge 4 of the machine an elongate aperture 6 for receiving a supply of tobacco as will be described in more detail below. The opening 6 opens into a chamber 8 defined by a bottom 10 (see particularly Figure 4), the leading concave edge 12 of a tobacco compacting member 14 and the concave surface portion 16 of a spoon member 18. (See also Figure 5). The spoon member 18 is secured to a spoon handle 20and the spoon handle 20 and spoon member 18 are movable from their positions as shown in Figures 1 and 2, to a tobacco injecting position as shown in Figure 3 to inject a wad of tobacco into a cigarette tube (which is shown at 22 in broken lines in Figure 3) and which is positioned on nipple 24 which is rigidly secured to the casing 2. The nipple 24 may be positioned within a corner cut-out portion 26 of the casing as shown in Figure 1.
The bottom 10 providing chamber 8 is secured to the casing 2 and as shown in Figures 2, 3 and 4, a tobacco compacting member 14 having a concave leading edge 12 is positioned for reciprocal movement in accordance with the arrows 30 and 32 in Figures 2 and 3, respectively, with this reciprocal movement being dependent upon the actual positioning and movement of the main operating lever 34.
The operating lever 34 is pivotally carried by the casing 2 by means of screw or stud 36. The lever 34 is of bell- :-crank lever configuration and the inner angled arm 38 of the lever 34 is pivotally secured to a link member 40 by means of pivot 42. The other end of the link 40 is pivotally secured to the tobacco compacting member 14 by means of pivot 44, and it will be appreciated that movement of lever 34 from the position :
shown in Figure 2 to the lateral position shown in Figure 3 will cause movement of the tobacco compacting member from the "open"
.
1(~3~6~3 : position shown in Figure 2 to the "closed" position shown in Figure 3 whereby tobacco positioned in the chamber 8 through opening 4 will be compacted against the concave spoon 16 to ; form a cylindrical rod of tobacco (not shown) ready for injection into a tube 22 positioned on nipple 24.
It will be noted from Figure 3 that the lateral move-ment of the lever 34 causes pivot 42 to move past dead centre between pivots 36 and 44. This is an important feature. During :: movement of the lever 34 from the position in Figure 2 to the .. 10 position in Figure 3 the tobacco compacting member will compact the tobacco to a maximum degree when all three pivots 36, 42 and 44 (pivots A, B and C) are in direct alignment, but it has been found that by withdrawing the tobacco compacting member a small amount after maximum compaction of the tobacco a more superior :
operation of the machine results, and enables the user to inject the wad of tobacco into a cigarette tube with less effort and with superior results. Thus, in operation, when the lever is moved in its tobacco compacting direction the tobacco compacting . member first squeezes the supply of tobacco and when the pivots 20 36, 42 and 44 are in alignment, exerts a maximum compression on the tobacco in the chamber, and then continued rotation results ; in some relaxation of the compaction to facilitate insertion of the wad of tobacco into the tube by movement of the handle 20 :
and spoon 16 from the position shown in Figure 2 to the position shown in broken lines in Figure 3.
Some cigarette making machines employ a tobacco compacting member which compacts a wad of tobacco into generally cylindrical rod configuration but all of these known machines utilize parallel links and an interconnecting toggle arm to ensure that the tobacco compacting member is maintained in precise alignment during its movement into the tobacco compacting position but it has now been found that the more complicated parallel link and toggle arrangement is not absolutely necessary and that a sinlge link pivotally mounted between the operating lever and the tobacco compacting member results in a highly satisfactory product with a minimum of moving parts. This arrangement removes the necessity of parallel linkages, toggle arms and camming surfaces of prior art constructions.
The inventive concept also contemplates in a further embodiment providing parallel slots 48 (see Figure 6) in the cutter 14 and by providing guides in the form of downwardly projecting studs 50 on the lower surface of the casing 2, and it will be appreciated that the slots move along the guides during movement of the lever to maintain the tobacco compacting member 14 in precise alignment with the concave spoon member 16 and between which the wad of tobacco is compacted. ~;
In operation the user pivots the operating lever 34 to ~, the position shown in Figure 2 which withdraws the tobacco . .;~ .
`~; compacting member 14 to the "open" position shown in this view.
The handle 20 and spoon 16 will also be moved to the position shown in Figures 1 and 3 so that the chamber is ready for the reception of a supply of tobacco. After the tobacco is positioned in the chamber, the lever 34 is then pivoted to the position -~ shown in Figure 2, whereby the tobacco (not shown) is compacted --~ in cylindrical rod form between the concave leading edge 12 of the compacting member 14 and the concave spoon 16. Handle 20 is then moved to the position shown in Figure 3 whereby the compacted wad of tobacco is injected into a tube 22 previously positioned on the nipple 24.
To retain the tube 22 on the nipple during injection a tube retaining lever 52 is provided. The lever 52 is also of bell-crank configuration and is secured for pivotal movement to the bottom surface of the bottom 10 by means of pivot 54. A spring _7_ ~ , .
` 10396(~3 56 e~tends between the side 58 of the casing and the lever 52 and the action of the spring is to normally hold the tip 60 on . the outermost end of the lever 52 against the nipple 24. The innermost end of the lever 52 is provided with a stud 62 which is positioned to be contacted by the link 40. When the handle ; 34 is in the position shown in Figure 2, the stud 62 is - contacted by the link 40 and the lever 52 is pivoted against the action of spring 56 to the position shown in Figure 2 wherein the tip 60 is removed from the nipple 24. It is in ~ 10 this position that a tube 22 will be positioned on the nipple 24. When the handle 34 is moved to the tobacco compacting position as shown in Figure 3, however, spring 56 is then able to move the lever 52 to the tube retaining position shown in . Figure 3.
It has been found that coating the leading edge 12 of ; the tobacco compacting member with TEFLON may be advantageous if the tobacco compacting member is made of metal. However, such a coating is not required if the tobacco compacting member is made of NYLON. TEFLON is a registered trade mark of E.I.

The nipple 24 may be positioned within a corner cut-out portion 26 of the casing as shown in Figure 1.
The bottom 10 providing chamber 8 is secured to the casing 2 and as shown in Figures 2, 3 and 4, a tobacco compacting member 14 having a concave leading edge 12 is positioned for reciprocal movement in accordance with the arrows 30 and 32 in Figures 2 and 3, respectively, with this reciprocal movement being dependent upon the actual positioning and movement of the main operating lever 34.
The operating lever 34 is pivotally carried by the casing 2 by means of screw or stud 36. The lever 34 is of bell- :-crank lever configuration and the inner angled arm 38 of the lever 34 is pivotally secured to a link member 40 by means of pivot 42. The other end of the link 40 is pivotally secured to the tobacco compacting member 14 by means of pivot 44, and it will be appreciated that movement of lever 34 from the position :
