CIGARETTE MAKING MACHINE Filed June 30, 1933 Patented Aug. 28, 1934 CIGARETTE MAKING MACHINE Desmond Walter Molins, Deptford, London, England Application June 30, 1933, Serial No. 678,491 In Great Britain July 26, 1932 4. Claims. (01. 131-43) Copending United States application Serial No. 60%,829 describes and claims a cigarette making machine by which a continuous cigarette rod is obtained having unfilled portions at intervals in which tubes of fairly stiff paper may be placed so that a cigarette having a tubular mouthpiece is obtained when the rod is cut, or if desired, the cutting point may be so chosen that the portion of the cigarette which is placed in the mouth contains a small amount of tobacco, after which comes the hollow portion which is then followed small piles at the points where the combsare farthest apart.

According to the present invention, means are 'provided for restraining or controlling the tobacco to preserveits level, while it is being subjected to the operation of the meansfor dividing the filler into separate portions.

Preferably, the controlling means consists of a number of fixed guide members, resting on the tobacco and through which the points of the separating combs may pass. 7

The invention will be more particularly described with reference to the accompanying drawing, in which:

Figure l is a section of a portion of a cigarette making machine, showing the modification to the parent invention.

Figure 2 is a section of Figurel on the line 'AA.

Figure 3 is an enlarged View of a portion of Figure 2.

Referring to the drawing, the paper 1 is carried beneath the tobacco feeding mechanism umrso mm l A'lE N'l, Q FFI 1131'} (not shown), and receives the tobacco shower in i the usual way.

The trough 2 which guides the paper web-beneath the tobacco feeding mechanism is of curved section, for example, semi-circular, so that the web leaves the filling trough beneath the tobacco feed in the form of a trough of paper carrying a quantity of tobacco which is'uniformly distributed along the length of the same.

The loaded web then passes to the mechanism shown in Figure l in which the long filler of tobacco is divided into a number of portions of,

' 2iv in length with a gap of, for example,

between the portions.

The mechanism for forming the gaps in the filler consistsv of a number of comb devices 3 and 4 arranged in pairsand carried on .a chain conveyor 5. t

The combs are of a width approximately equal to the width of the guide trough as shown in Figj ures 2 and 3, and are so moved that a pair of combs in contact with one another are caused to enter the trough from above at the point B and pass into the tobacco nearly as far as the bottom of the trough.

As the combs move along in the same direction as the loaded web is travelling they are caused to separate from one another by any suitable device so that when the combs are approaching the point C at the end of the lower path of the conveyor, they are separated from one another by the distance of mentioned above.

Under these circumstances, a gap of is formed between each section of the filler, and. the combs then move vertically upwards out of contact with the tobacco filler so that they do not disturb the same.

The raising and lowering of the combsinto the guide troughs is efiected by causing the combs to travel along a guide 6,.the separation of the rear comb from the front comb being effected in the manner described in the parent specification.

In order to prevent the tobacco from rising above its normal level whilst it is being subjected to the action of the combs, restraining means are provided in the form of guide members 8 through which the combs may pass as shown in Figure 3; The guides 8 are fixed at their ends to pins 9 which are in turn fixed to a bracket on the machine bed.

It will be seen that by the use of these guide members the tobacco filler is kept-under control during the period in which thespaces beforementioned are being formed, thus keeping the Ill!) tion of the finished cigarette has tobacco on either side of it, a firm portion of the cigarette rod is presented to the knife of the machine.

What I claim as my invention and desire to secure by Letters Patent is:-- V v e 1. In a cigarette making machine, the combination with means for guidinga web of cigarette paper loaded with tobaccofiller in a predeter-,

mined path, of means for engagingand separating the filler at spaced points to'provide gaps in-,

terrupting the continuity of the filler, and means disposed above the tobacco filler to restrain the filler during the separation of the same.

2. In a cigarette making machine, the combination with means for guiding a web of cigarette paper loaded with tobacco filler in a predetermined path, of meansfor engaging and separating the filler at spaced points to provide gaps interrupting the continuity of the filler, said means comprising two members supported for movement into and with the filler and means for displacing said members relatively lengthwise of the filler during the movement of said members with the filler to effect separation of the latter, and means disposed above the tobacco filler to restrain the filler during the separation of the same.

3. In a cigarette making machine, the combination with means for guidinga web of cigarette paper loaded with tobacco filler in a predetermined path, of means for engaging and separating the filler at spaced points to provide gaps in' terrupting the continuity of the filler, said means comprising two members supported for movement into and with the filler, means for displacing said members relatively lengthwise of the filler during the movement of said members with the 'filler to effect separation; of the latter, a continuous conveyor for supporting. said members, and means disposed above this latter filler to restrain the filler during the separation of the same.

4. In a cigarette making machine, the combimined path, of means for engaging and separating the filler at spaced points to provide gaps interrupting the continuity of the filler, said means comprising two members supported for movement into and with the filler, means for displacing said members relatively lengthwise of the filler during the movement of said members with the filler to efiect separation of the latter, said means comprising a conveyor so supported that a run thereof lies above and extends substantially parallel to the path'of movement of the web, a pair of members supported by said conveyor and having filler-piercing portions movable into and with said filler in closely adjacent relation, and means for supporting the filler-piercing portion of said members during movement thereof with the filler to efiect separation of the latter, and means disposed above the tobacco filler to restrain the filler during the separation'of the same,

said means comprising a plurality of guides spaced apart to allow a free passage for the filler-piercing portions.
