WRAPPING-MACHINE.

Specification of Letters Patent.

Patented Oct. 7,1913.

Application filed April 6, 1904. Serial No. 201,861.

To all whom it may concern Be it known that I, SYDNEY I. PnEsco'r'r, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in \Vrapping- Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in wrapping machines, and has for one of its objects to produce an improved form of wrapping mechanism which will be simple in construction and efficient in op eration.

A further object of the invention is to produce an improved wrapping machine in which the wrapper shall be delivered to the wrapping mechanism by means of a belt and on which the wrapper is held, the belt being rotated to deliver the wrapper and the wrapping mechanism taking the wrapper from the belt.

A further object of the invention is to produce an improved wrapping machine in which the wrapper is presented to the wrapping mechanism by a belt upon which the wrapper is held, either the belt or the wrapping mechanism, or both, during the wrapping operation, being given suitable movements to properly present the wrapper to the wrapping mechanism.

Nith these and other objects in view, the invention consists in certain constructions and in certain parts, improvements and combinations, as will be hereinafter fully described and then specifically pointed out in the claims her unto appended.

in the accompanying drawings Figure 1 is a plan view of so much of a wrapping mechanism as is necessary to an understanding of the invention, the wrapping mechanism proper being removed. Fig. 2 is a side elevation, partly in section, of the construction shown in Fig. 1, the wrapping mecha nism being shown in its proper position in said view. Fig. 3 is an end view of the construction shown in Fig. 1. Fig. i is a detail view of the mechanism for transferring the wrapper to the wrapper presenting belt. Fig. 5 is a detail sectional view illustrating more particularly the blast mechanism for transferring the wrapper from the belt. Fig. 6 is a detail view of one of the cams and its connections. Fig. 7 is a detail sectional view of the mechanism for swinging the presenting belt, and Fig. 8 is a sectional detail view illustrating a modification.

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 construction, the sheet or material from which the wrapper is cut will be retained in position with respect to the die by suction, though other suitable retaining devices might be employed. In general, the cutting mechanism, in the preferred form, will be substantially similar to that illustrated in the patent to R. L. Patterson and George Arents, Jr., as the assignees of Oluf Tyberg, No. 654,203, dated July 24, 1900. Reference is made to this patent for a detailed description of the mechanism.

For the purposes of the present application it is sufficient to say that a leaf of tobacco is placed on a perforated bed 2, said bed being provided with a knife 3 of suitable configuration. A suitable suction producing mechanism, such, for instance, as described in the patent referred to, is caused to hold the leaf on the bed, after which the wrapper is cut by a roller 4 supported on an arm 5, this arm being mounted on a carriage 6. This carriage reciprocates in suitable ways 7 on the bed, this reciprocating movement being produced by a lever 9 which is connected to the carriage by a link 10. This lever is mounted on a shaft 11 suitably sup ported in the frame, said shaft having an arm 12 extending therefrom. This arm is connected by a link 13 to one of the a ans 14 of a bell-crank lever lil5, said lever being pivoted to a stud 16 mounted in the frame of the machine. The arm 15 of the bell crank lever is provided with the usual cam roller which engages a cam groove 17 in a suitably formed cam mounted on a cam shaft 18 suitably supported in the frame.

After the wrapper has been cut, it is, by mechanism which will be hereinafter described, transferred to a wrapper presenting means. This means, in the preferred construction embodies a wrapper presenting belt which may be mounted in various ways and operated by widely varying constructions, and the wrapper may be held thereon in various ways. In the preferred form of the construction, and as shown, however, the belt, which is marked 19, will be provided with perforations 20 so that the wrapper may be held thereon by suction. While the suction mechanism may be, as has been suggested, of any suitable form, in the preferred construction and as shown, the belt will be mounted in a box 21 having a slotted top and bottom, the edges of the slots being shouldered, as indicated at 22, to form a guide for the belt. As illustrated, the belt is mounted on rollers 23 suitably supported in the box, and in the preferred construction, these rollers will be provided with grooves 2% which register with the rows of perforations in the belt.

The wrapper after being cut in the manner described hereinbefore or by any other suitable mechanism must be transferred to the belt. This may be accomplished in any suitable way and will preferably be accomplished by moving the bed on which the wrapper is cut. The mechanism by which the bed is moved to bring it into position to transfer the wrapper may be of any suitable description As shown, the bed. 2 and knife 3 are mounted on a plate 25 said plate being provided with a dove-tailed projection 25 which moves in a suitable groove 26 in a bed 26 mounted on the frame of the machine. The plate 25 has mounted on it a stud 27, said stud being engaged by a forked lever 27 on a vertical shaft 28 suitably mounted in the frame of the machine. This vertical shaft has extending therefrom an arm 29 which is provided with a bowl 30 which engages with a suitable cam groove 31 in a cam mounted on the shaft 18 before referred to. d

The suction is produced in the bed by means of a suitable suction mechanism, such, for instance, as a fan, not shown, the connections from the fan to the cutting bed including suitable pipes, such, for instance, as pipes 32. In order that the suction may not be cut off during the movement which the bed is given to bring the wrapper into suitable position to be transferred to the belt, suitable telescopic connections are provided, these connections including short tubes 33 (see Fig. 4) which are connected to the bed, said tubes telescoping into the pipes 32 when the bed is given its movement.

The movement of the cutting bed hereinbefor'e referred to positions the wrapper in the particular construction shown, beneath the under run of the belt, so that it may be readily transferred to the belt. The construction by which the transfer of the wrapper from the cutting bed to the belt is effected may be of any desired character, but it will preferably be effected by moving the 1 bed. In the construction shown, the bed is provided with a depending lug Bet (see Fig. e and dotted lines in Fig. 1) which moves in suitable guides 35 secured to the plate 25. hen the cutting bed has been shifted in the manner hereinbefore described so as to bring the cut wrapper into position beneath the under run of the belt, this depending lug 8 1 comes over and registers with a plunger 36 mounted on the bed 28 which bed is suitably secured to the main frame. This plunger 36 has on its lower end a collar 37 which is engaged by a forked lever arm 39 extending from a hub a0, said hub being supported on a stud 41 carried on a bracket attached to the main frame of the machine. This hub 10 has extending from it a second arm 12 which is provided with a suitable bowl engaging with a cam groove in a cam 43 mounted on the shaft 18 before referred to. The cam is so shaped that when the cutting bed carrying the cut wrapper comes into position beneath the under run of the belt, it will, through the mechanism described, raise the bed, thus throwing the wrapper up against the suction belt which at this time will be stationary. While the suction might be out ofi to permit the transfer of the wrapper, in the preferred form of the construction. the suction operating through the perforations 20 in the belt will. be strong enough to take the wrapper from the suction bed.

After the wrapper has been transferred by the mechanism described, or by any other suitable mechanism, to the belt, the belt will be caused to travel in order to bring the wrapper into proper position sothat it may be presented to the wrapping mechanism.

he movement of the belt may be effected by agencies which difier widely in construction. In the construction shown, one of the rollers 23 has its shaft 44- extended outward from the box and to this shaft is connected a flexible shaft 45, the connection being effected by means of a collar 40 or in any other desired manner. This flexible shaft e5 has its other end supported in a bearing 47 which is supported in a bracket 18 0X- tending outwardly from the machine frame. The end of the shaft 45 is provided with a spiral gear 19 which meshes with another spiral gear 50, this spiral gear being supported on a stud 51 mounted in the main frame of the machine. Mounted on this stud 51 is a gear 52, the said gear being fast to the spiral gear 50. This small gear 52 is at proper times actuated by a segment rack 53 secured to a disk 54 mounted on the shaft 18 before referred to. It will beseen that through the construction which has just been described, the belt will be given an intermittent traveling or rotating movement, the segment rack 53 being long enough to produce a sufficient movement of the belt to cause the wrapper to be delivered to the wrapping mechanism.

The wrapping mechanism may be of any desired construction, and may be located in any desired position with respect to the belt. In the preferred construction, however, and as shown in Figs. 2 and 3, the wrapping mechanism will be located over the belt. The construction of wrapping mechanism illustrated in Figs. 2 and 3 is in its general features of the type disclosed in the patent to Reuse No. 552,447, granted December 81, 1895. The wrapping will be efiected by means of pairs of intermeshing aws 55 operating through suitable gearing in the manner generally indicated in the said Reuse patent.

In the construction shown in Fig. 8, the wrapping mechanism indicated is of the ordinary roller form, the rolls being marked 56, and these rolls are located at one end of the belt instead of over it, as is the case in the other figures. It is obvious that the wrapping mechanism might be placed under the belt if desired, but this modification being obvious no illustration is deemed neccssary.

The wrapping mechanism may take the wrapper from the presenting belt in various ways, but there will preferably be emloyed positive agencies for transferring one end of the wrapper to the bunch or other object in the wrapping mechanism. In the construction shown, this transferring mechanism consists of a blast mechanism. In the construction shown in Figs. 1, 2, 3 and 5, there is provided a blast pipe 57, said pipe communicating with a suitable blast mechanism, not shown, and this pipe communicates with a guide 58 which is formed in one of the walls of the box 21. Connecting with this guide is a short bent pipe 59, the opening in which registers with a line of the perforations 20 in the belt. This blast may act either constantly or intermittently, as desired. In the construction referred to, when the point of the wrapper reaches the proper position beneath the jaws it also overlies the opening in the blast pipe and is blown upward by the blast into the grasp of the jaws.

The construction shown is intended for wrapping tapering cigars. In order that the wrapper may be properly presented to the cigar, means are provided for effecting a relative angular movement between the presenting belt and the wrapping mechanism during the wrapping operation. While this might be accomplished in various ways, in the best constructions, it will be effected by swinging the presenting belt. The mechanism for thus swinging the presenting belt may be varied within wide limits. In the construction shown, see more particularly Figs. 3 and 7, the frame is provided with a circular boss or collar 60 and the box 21 is provided with a downward projecting tubular extension 62 which projects through the boss, the box being provided with a shoulder so as to be seated on the boss. The lower end of this tubular extension 62 is provided with a segment gear 63 which is engaged by a segment 64 mounted on a lever 65, said lever being pivoted on a stud 66 depending from the under side of the frame. The lever carries on its other end a bowl 67 which engages with a cam groove 68 in a cam mounted on the shaft 18 before referred to.

hen the machine is to spirally wind. a wrapper about an article to be wrapped, as is the case in wrapping cigars, for instance, a relative traversing movement will be effected between the wrapper presenting belt and the wrapping mechanism. While this may be effected in various ways, in the preferred construction, it will be effected by causing the wrapping mechanism to receive a bodily traversing movement. The traversing movement may be eliected in any desired manner, as, for instance, in the manner illustrated in the patent granted to Patterson and Arents, as assignees of Oluf Tyberg, No. (354,195, dated July 24:, 1900. In the construction illustrated, the wrapper carrying jaws and the gears and shaft which operate them are mounted in a frame 69 mounted on two rods 70 which are sup ported in arms 71 extending upward from the frame of the machine. The gears which drive the jaws receive their motion primarily from a long gear 7 2 mounted on a shaft 73 ournaled in the arms 71, this shaft being driven in any suitable manner, as, for instance, by a belt pulley 7a. One of the gears which forms a part of the train which drive the jaws, as, for instance, the gear marked 75, is constantly in mesh with the long gear 7 2. The traversing movement of the wrapping mechanism is effected by means of a lever 76 pivoted at 77 in a bracket on the side of the frame, this lever being connected to the frame 69 by means of a link 78. The other end of this lever 76 is provided with a bowl which engages a suitable groove in the side of a cam drum, this drum being the one in which the cam groove 68 before referred to is formed.

Changes and variations may be made in the mechanisms by which this invention is carried into effect. The invention is not, therefore, to be limited to the specific details of construction hereinbefore described and illustrated in the accompanying drawings.
