To all whom it may concern:

Be it known that I, OLUFTYBERG, a citizen of the-United States, residing in New-York, county ofKings, and State of New York, have invented certain new and useful Improvements in Wrapping-Machines, fully described and represented in the following specification and the accompanying drawings, forming a.

part of the same.

:o This invention relates to certain improvements in wrapping-machines, and has for one of its objects to produce an improved form of wrapping mechanism for'wrapping cigars or similar articles which will be simple inconstruction and efficient in its operation. A further object of the invention is to produce an improved wrapping-machine in which the wrapper shall be taken by the wrapperpresenting devices as it is out, said presenting devices cooperating with and forming a part of the cutting devices and thereafter operating to present the wrapper to the wrapping mechanism.

A further object of the invention is 'to produce an improved wrapper-cutting mechanism.

With these and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combi-v a plan view of the construction shown in Fig.

1. Fig. 4isadetail sectional elevation of the cutting-die and its bed, and Figs. 5, 6, and 7 are diagram matic views.

Referring to the drawings'which illustrate a concrete embodiment of the invention, 1

indicates the frame, which may be of any suitable configuration. In the construction shown the wrapper which is to be presented to the wrapping mechanism hereinafter described is cut in the machine by a die and a cooperating member, and in the preferred.

form of the construction the leaf orsheet material from which the wrapper is cut will be retained in positiorrwith respect to the die by suction, though-other retaining devices might be'employed. As sh'own, the frame of the machine is provided with a chamber 2, with which communicates a pipe 3, leading to a blower or any other convenient suctionproducing means. The top'of' the chamber is formed by a perforated plate 4, u pon which rests a box or table 5, said box or table forminga chamber which is in communication with the suction-chamber 2 through the perforations in plate at. This box or'table has an opening in its top in which the cutting-diet being shown as a closed die and of a configuration suitableto form a wrapper for a cigar. The die is arranged to fit loosely in the open- ,ing in the table 5, so as to leave a space 7, through which the suction acts to hold'a leaf on the table.

' In cutting thin sheets of material by means of dies which have two opposite sides difficulty is frequently experienced in obtaining a clean cut, for the reason that the two sides of the die may not be ground to lie exactly in the same plane or forthe reason thatthe face'of the cooperating cutting member may not always lie in a single plane. In the preferred form of the construction, therefore, the die will be arranged so that while it is positively supported it will be capacitated to tilt in order to compensate for any inequalities. The construction of the die to efiect the function or purpose referred to may be varied within wide limits. As shown, the base 8, which carries the die and with which the die is shown as integral, is cut away, as indicated at 9, so as to form a knife-edge bearing, upon which the base and die are pivoted. While 0 this knife-edge bearing constitutes a preferred form of"construction, it is possible to employ other forms of pivotalsupports for the die which will permit the desired tilting movement. When the term pivotal, therefore, is herein used, it is to be construed as covering any form of positive support upon which the die is permitted to roc In order to keep the die from shifting its mental bearing, (indicated in dotted lines at ]Q in Fig. 4,) said bearing engaging with a is located, said die in' the present machine 65 I position, it is or may be provided with a seg- Ioo small box 11, also shown in dotted lines in this figure.

The cutting member which cooperates with the die may be of any suitable description. Preferably, however, it will be a roller, and in the machine shown this roller is also the wrapper carrier and presenting device.

Broadly considered and as independent of the cutting mechanism which has just been described, the wrapper-presenting means may be widely varied in character, although it will be'mounted in a suit-able carrier with respect to which it rotates. As shown, the carrier for the wrapper-presenting means consists of a pair of arms 12 13, mounted on a shaft 14, journaled in suitable bearings 15, secured to the frame. These arms serve to support a sleeve 16, whichis journaled in the arms, and upon this sleeve is mounted the wrapperpresenting means proper, which comprise in the present construction a perforated cylinder 17. The perforations in this cylinder are so arranged that as the roller rotates it will pick the leaf up from the perforated plate which lies-inside the die, the perforations preferably taking the leaf close to the inner edge of the die, the suction created in the cylinder causing the-leaf to adhere thereto.

The means for establishing the suction in the cylinder may be of any suitable character. As shown, the sleeve 16 is slotted at 18 and the arm 12 is formed with an air-passage therethrough, said passage being in communication with a pipe 19, which leads to a fan or other suitable suction-producing means.

' It is apparent that by giving the carrier a suitable movement the cylinder 17 will be caused to roll over the cutting-die and that a wrapper will be cut from a leaf of tobacco or other sheet of material which has been previously laid upon the die, said wrapper being picked up and carried onward by the cylinder 17, it being of course understood that the suction in the cylinder will be strong enough to take the wrapper away from the perforated bed of the die in case the suction is not cut otffrom the chamber beneath it, which may, however, be done.

The means for producing the movement of the carrier maybe varied Widely. As shown, the shaft 15 is provided with a segment 20, which is engaged by a segment rack 21, formed on'the arm 22 of a bell-crank lever 22 23, said lever being pivoted to the frame at 24. The arm 23 of the lever is or may be provided with a cam-roll 25, which engages with a cam-groove 26, formed in one of the faces of a cylinder 27, mounted on a cam-shaft 28. The shaft 28 may be driven in any suitable manner. As shown, it is provided with a worm-gear 30, which is in engagement with a worm 31, mounted on the main driving-shaft 32, said shaft being shown as provided with a driving-pulley. 33.

In order to prevent any slip between the cylinder 17 and the die as the cylinder rolls over the die, the cylinder will preferably be positively driven, the driving being efiected by any suitable mechanism. As shown, the sleeve 16,which carries the cylinder 17, is provided with a sprocket-wheel 34, over which passes a sprocket-chain 35, said chain also passing over a sprocket- Wheel 36, loosely mounted on the shaft 15. Secured to this sprocket-wheel 36 is a gear 37, said gear being driven by a segment-rack 38, formed on the arm 39 of a bell-crank lever 39 40, pivoted at 41 to the frame of the machine. The arm 40 of the bell-crank lever is or may be provided with a cam-roll 42, which engages with a cam 43, formed on the end of the cylinder 27, the bell-crank being held up to its duty by means of a spring 44.

After the cylinder 17 has passed over the cutting-bed and cut and picked up a wrapper the movement of the carrier is continued to bring the cylinder into position to deliver the wrapper to a wrapping mechanism. The wrapping mechanism employed may be of any suitable character, that illustrated being of the well-known Reuse type, the wrappingjaws 45 being mounted on and driven bysnitable shafts and gearing and the whole being mounted in a suitable frame 46. The main driving-shaft for this wrapping mechanism is marked 47, said shaft being provided with a bevel-gear 48, which meshes with a similar gear 49, mounted on a vertical shaft, the other end of said shaft being provided with a beveled gear 50, which meshes with a similar beveled gear 51, mounted on a'counter-shaft 52. This counter-shaft is provided with agear 53, which is in mesh with a gear 54, mounted on the main (l riving-shaft 32. The wrapping mechanism illustrated is substantially the same as that illustrated and described in Patent No. 654,178, granted July 24, 1900, to R. L. Patterson and George Arents, Jr., as my assignees, and a fuller description herein is unnecessary, as reference may be had to said patent for a full disclosure of the construction.

In cigar-wrapping machines it is desirable that a relative movement be produced between the wrapper-presenting means and the wrapping mechanism, which movement is the resultant of an approaching and traversing movement or an approaching, traversing, and angular movement for reasons fully set forth in Patent No. 654,178, granted July 24, 1900, to R. L. Patterson and George Arents, Jr. In the present machine provision is made for producing a relative movement between the wrapping mechanism and the wrapper-presenting means which is the resultant of the three movements referred to, although the relative movement will vary, according to the shape of the article to be wrapped. In the present machine the wrapping mechanism is given the angular movement, the frame 46 having secured to its under side a segment 55, which is engaged by a segment 56, formed on the arm 57, which is mounted on a vertical shaft 58. The other end of this shaft carries an arm 59, which is or may be provided with a cam-roll 60, which engages with a camgroove 61 in the cylinder 27. The approaching movement or the movement which deliv-' ers the wrapper is produced by rotating the,

ashape that it' not only rotates the cylinder as it runs over the bed during the wrappercntting operation, but also rotates it during the wrapper delivering operation. In the present machine the traversing movement is given to the wrapper-presenting means by mechanism which will now be described.

Referring to Fig. 2, it will be seen that there is located in the sleeve 16 a block 62, to

which the cylinder 17 is connected by means .of a pin 63, said pin passing through slots'in the sleeve 16. Projecting from this block 62 is a stem 6 1, having on its outer end a grooved collar'65, which is engaged by a lever 66, pivoted at 67 to the carrier-arm 13, so as tomove with said arm. The lowerend of this lever 66 is provided with a pin which engages with a grooved collar 68, loosely supported on the shaft 14. This collar 68 is also engaged by a pin 69 on an arm 70, projecting from a short shaft 71, supported in a suitable bearing 72,, secured to the frame of the machine.- The other end of this shaft 71 carries an arm 73,

.which has on its inner end'a cam-roll 74,

which engages with a suitable cam-groove formed in the end of the cylinder 27. This groove is so shaped as to produce through the connections described a sliding movement of the cylinder 17 with respect to-the sleeve upon which it is supported in the carrier-arms, this traversing movementbeing sufficient to cause the wrapper to be fed along the bunch in the wrapping mechanism.

It may be here remarked that under certain circumstances either the traversing or the angularmovement, or both, might be omitted. It will also be understood that both travcrsing and angular movements might be given to the wrapping mechanism, if desired.

In delivering the wrapper it is desirable that that part of the circumference of the cylinder17 which is delivering the wrapper stand directly opposite the opening in the wrapping mechanism in order that the lead .of the Wrapper between the cylinder and the wrapping mechanism may be as short as pos- When, however, the wrapping mechanism is given an'angular movement, the

swing of this mechanism would tend, were the wrapper-presenting cylinder stationary with respect to the wrapping mechanism, to

move the mechanism away from that partof the cylinder which is delivering to the wrapper, thus increasing the length of the lead of the wrapper. To avoid this, meansare preferably provided to produce a relative compensating movement between the wrapping mechanism and the wrapper-presenting means. In the machine shown this is effected by moving the wrapper-presentingmeans.

Referring to the diagram, Fig. 5, in which the wrapper-presenting cylinder is shown as delivering the forward or tuck end of the wrapper to the bunch, and comparing the relative position of the wrapper-presenting cylinder in this figure with the positions illustrated in Figs. 6 and 7, which show the cylinder as delivering the wrapper to the center and tip ends of the bunch, respectively, it will be noted that the cylinder has moved back somewhat from the extreme forward position illustrated in Fig. 5. This backward movement is effected through the carrier-operating means, the cam 26 being properly shaped and timed to produce this backward or compensating movement during the wrapper-delivering operation.

Means are preferably provided to insure the positive presentationof theleading or tuck end of the wrapper to the bunch. While these means may be varied in character, a blast mechanism will be preferably employed for this purpose. In the construction shown the sleeve 16 is provided with a recessed block 75, which'is shown as integral with the sleeve, the recess in said block communicating with those perforations which underlie the forward or tuck end of the wrapper when it is positioned on the cylinder 17. Communicating with the recess in .the block 75 is a blast-pipe 76, said pipe being led through the mechanismsuch, for instance, as a fan.

The parts are so arranged that the angular bend on the pipe 76 and the nozzle come into register at the precise time-when the tuck end of the wrapper is positioned over and is to be delivered to the tuck end of the bunch.

It will be understood that changes and variations may be made in theconstruction by which the invention is carried into effect. It will further be understood that certain parts of the construction in which the invention is embodied may be used independently of other parts. The invention is not, therefore, to be limited to the precise constructions and combinations hereinbefore described.
