MACHINE FOR MAKING CIGABILLOS AND THE LIKE.

Application filed November 5; 1921. Serial No. 513,173.

To all whom it may concern:

Be it known that I, ADoLr BAnenBonR, a subject of the Queen of the Netherlands, residing at Rotterdam, Netherlands, have invented certain new and useful Improvements in Machines for Making Cigarillos and the like, of which the following is a specification.

In the manufacture of cigaril'los machines are employed comprising a hollow casting having a curved top face formlng a rolhng table provided with a groove or depression for receiving the tobacco and ad acent to said groove with a number of perforations. A belt of leather or other suitable materlal stretched over said .curved top face is passed over a set oftwo rollers arranged the one overthe other and adapted to reciproe cate along the table, the belt being likewise provided with perforations to coact with those in the table. r

The wrapper, i. e. the tobacco-leaf in which the roll of tobacco is to be wrapped, is placed on the perforated portion of the leather belt and caused to be held thereon by atmospheric pressure owing to a vacuum being set up in ,the hollow castlng. After the tobacco has been deposited on the leather,

belt vertically above the groove in the rolling table and forced thereinto together with that portion of the belt by which it is sup-' ported, the rollers over which the belt is passed are moved along the table whereby the tobacco is lifted out of the. groove and rolled in the wrapper, which has oneof its edges .gummed, whereupon the complete cigarillo is discharged. 7

It has already been suggested to employ in combination with a machine of the above type a second hollow member or receiver,

and a third hollow member or transporter, these members having a perforated cover and a perforated bottom r spectively and each provided with means for producing a vacuum therein, the transporter be ng adapted for movement between and for alternate cooperation with the rolling table In such machines the and the receiver. y wrapper isplaced on theperforated cover of the receiver and subsequently conveyed by .the transporter to the rolling table,.it being understood that vacuum is successively set up in the receiver, .in the transporter and in the hollow casting forming the rolling table.

My present invention has for its object over the receiver the cover is certain improvements of the last mentioned type of machines and more particularly to provide improved means whereby the wrapper while supported by the receiver may be automatically gummed and cut so that from" the moment an attendant has placed a wrapper on the ;rece1ver no further manual op-v erations are required and the manufacture of the cigarillo is performed throughout automatically. I

With this object in view I provide a frame carrying the transporter, a cutting roller and a gumming brush, and I support fthis ordinarily offers serious diificulties owing,

amongst others, to the irregular form of the wrapper and to the requirement that the gumlning-brush should be prevented from contact with the knife. I therefore provide the perforatedcover of the receiver with an outwardly sloping end portion the extreme edge of which 1s normally at a certain d1s tance above the knife edge. I further hinge said cover along the side opposite the sloping portion and I provide means whereby it'is yieldingly held in its normal position,

thelarrangement being such that when the gumrning brush moves in contact with said sloping portion the, cover .will not yield and theknife edge cannot begummed, but that duringthe movement of the cutting roller depressed so as to uncover the knife.

The presence of holes in thewrapper may cause some glue to adhereto the outwardly sloping end portion of the receiver'cover. In ordernow to prevent the cutting roller from taking up. this glue I provide the frame carrying this roller with an abutment adapted for coaction with a projection of the hinged receiver cover so that the cover is sufficiently depressed when the cutting roller moves over same] I V Another nconvenience, exper enced m prior constructions is that during the transport of the wrapper the gummed edge of the same may curlwhereby the wrapper would not assume the proper position on the roller table. In order to overcome this difliculty I propose to provide the transporter with a movable member having a flat face adapted during the transport of the wrapper from the receiver to the rolling table to contact with the gummed edge through its entire length so that said edge sticks to this face. The said member, which may be termed edge protector, is adapted to be forced out of contact with the gummed edge of the wrapper after the latter has been deposited on the rolling table and held thereon by atmospheric pressure so that the gummed edge is prevented from curling. The movement of the edge protector off the wrapper may simply be brought about by a push arm secured to the stamper for forcing the tobacco into the rolling table groove, and a stationary abutment may be provided on the receiver for returning the edge protector into its original position.

The annexed drawing illustrates, by way of example only, an embodiment of my present invention, Figure 1 being a side elevational view thereof showing some parts in cross section, whereas Figs. 2 and 3 are a side elevational view, partly in section, and a cross sectional view of the transporter and of the receiver, respectively.

In viewvof the above statements a brief description will suffice for explaining the construction and the modus operandi of the illustrated machine.

The stationary frame 1 serves to support the hollow casting 2, the curved top of which forms the rolling table. Said top is provided with a cross groove 3 for receiving the tobacco, and part of the top adjacent to this groove is provided with perforations 4. Stretched over the rolling table is a leather belt 5 passed over rollers 6, 7 at the topend of an arm 8, which is pivoted to the frame 1 as at 9. The right hand end of the belt 5 is secured to the hollow casting 2 as at 10, the left hand end thereof being connected through a coiled spring 5 to the frame 1 so that the belt is always stretched. A stamper 11 secured to the end of an arm 12 serves for pressing the tobacco into the groove 3.

The stationary receiver is designated by 13, the transporter by 14, and these members and also the hollow casting 2 are provided with means whereby they may be connected to a vacuum space.

The wrapper for a cigarillo to be formed on the rollingtable is placed on the cover of the receiver 13 whence it is conveyed by the transporter 14 to the perforated portion of the rolling table. The transporter 14, which is provided with a nozzle 16 for the connection of a flexible vacuum pipe, is carried by a frame 15 through links 17, 18 of equal lengths and pivoted to the transporter 14 and to the frame 15 in such a manner as to always remain parallel the one with the other. To the link 18 is secured an arm 19 carrying an anti-friction roller 20 guided by a suitably curved slot 21 in frame 1. By these means the transporter 14 may be moved into its extreme left hand and right hand positions to coact with the rolling table 2 and with the receiver 13, respectively.

The frame 15 carries a brush 22 adapted during the movement of said frame 15 to the right to come into contact with a cylinder 23 revolving in a container 23 partly filled with glue, whereby the brush takes up some of the glue to spread it out on the right hand side edge portion of the wrapper supported by the receiver 13.

A roller 24 mounted on the frame 15 is adapted for coasting with a knife to be described in further detail hereinafter.

The frame 15 is supported at its left hand end, as at 25, by the arm 8, and at its right hand side, as at 26, by an arm 27. Arm 8 is pivoted to one endof a rod 28 having its other end hinged to a rod 29 pivotally mounted on the frame 1. Said rod 29 car: ries an antifriction roller 30 held in contact with a cam 31 by means of a spring 29?...

The arm 27 is pivoted to a bell crank lever 32, 33 pivoted to the frame 1 as at 32 and having an antifriction roller 34 cooperating with a cam 35.

The arm 12 is secured to an arm 37 pivoted to the frame 1 as at 37- and carrying an antifriction roller 38 contacting with the periphery of a cam 39.

Cams 31, 35 and 39 are keyed on a com mon shaft 40.

The transporter14, see Fig. 2, is. in the I form of a casing having a perforated bottom 41 and lugs 42, 43 for receiving the pins with which it is pivoted to links 17 18. Mounted on a stud 44 is the edge protector 45 having its under face flush with the bottom face of the transporter when assuming the position shown. Said edge protector 45 is provided with a projection 46 and loadedby a coiled spring 47 which is secured to a fixed pin 47 of the transporter and to a pin 47 of the edge protector so as to hold the latter in the position shown, or in aposition wherein it is turned away from the casing, dependent upon whether the pin 47- is at the left hand side or at the right hand. side of this line passing through pivotv 44. and pin 4 K The receiver 13, see Fig. 3, is in the form of a casing having a perforated cover 48, a knife 49 being screwed to the right hand side wall and adapted for coaction with the roller 24 (Fig. 1). The cover 48 has an enlarged right hand end portion having an outwardly sloping face 50, the outer edge of which is normally at some vertical distance, above the cutting edge of knife 49,

Along its left hand edge said cover is hinged.

spring 48 always tends to hold the cover 48 sociated therewith is again moved to the to the casing by means of a pin 51.

in contact with a fixed stop member 48 in the. position shown. However, when an abutment. 52 of frame 15 (Fig. 1) engages .a roller 53 mounted onalaterally projecting part of cover 48, the latter is depressed against the action of spring48. 1

The receiver is further provided with a finger 54 adapted to coact withthe projection 46, which further cooperates with a .finger 36 on arm 12.

The modus operandi of the described arrangement is as follows: I

A wrapper is placed on the receiver cover 48 and cut at its right hand side edge by the roller 24 moving over the cutting edge of knife 49, whereupon the brush 22 gums the 7 which periods vacuum is applied to the receiver 13, the transporter 14 and. the hollow cas1ng2 in the course of these operations.

When the roller 24 moves over receiver 13, the cover 48 is depressed by the coaction of the abutment 52,-and roller 53 so that the roller 24 cannot come-into contact. with gum that may be on the sloping face 50. When the abutment 52 releases roller 53, i. e. before the brush 22 has reached the sloping face, the cover 48 resumes its normal position under theaction of spring 48, so that said brush is adapted to spread its gum on that portion of the wrapper which is supported by the sloping face 50.

After the brush has done its duly, the transporter 14 is placed in proper position on the cover 48 whereby the projection 46 engages the finger 54 and the edge protector 45 is returned into the position shown in full lines in F ig. 2, so that the bottom face of said protector may engage the gummed edge portion of the wrapper. At this moment vacuum is applied in the transporter casing and atmospheric pressure conditions restored in the receiver casing whereby the wrapper is forced against the bottom face of the transporter.

As soon as the wrapper carrying transporter has assumed its proper position on the rolling table, the Stamper 11 moves down, thereby forcing the tobacco, which has previously been placed on the belt 5 vertically above the groove 3, into said groove together with part of the belt. At the same time the finger 36. engages the projection 46 so as to impart to the edge protector 45 an angular motion whereby the latter is'forced off the wrapper. Subsequently atmospheric I1. Ina machine for manufacturing pressure is restored in the transporter casing and vacuum applied to the casting 2, 'so that right for preparing and pickingfupa next;

wrapper, and the cigarillo is rolled on the rolling, table in theordinary manner.
