CIGAR-BUNCI-I MACHINE.

Application filed VFebruary 7, 1925. Serial No. 7,482.

Our invention relates to an improvement in cigar bunch machines and more particularly to improvements in the mechanism for effecting the transfer of binders from the cutting mechanism to the rolling table.

Cigar bunch machines, and especially those of the automatic type, have heretofore been provided with mechanism adapted to effect the trimming or cutting of a leaf of tobacco to form a binder adaptable for rolling about a filler to form a bunch, and -in cooperation with such mechanism a device for transferring the binder yfrom the cutting mechanism to suitable rolling mechanism, as a rolling belt, for its application to a filler supplied to the rolling mechanism.

Such mechanism as has heretofore been utilized for this purpose, while of a substantial degree of leliiciency, has been found to be not entirely satisfactory in operation and of undue complication in structure and adj ust-ment.

'More particularly, such mechanisms have been found to be unsatisfactory in that the transferring devicein delivering the binder to the rolling belt has a tendency -to overreach the predetermined point of -delivery due principally to the effect at the end of the transferring` arm ofthe sum ofthe lost motions in its opera-ting mechanism. Further, such mechanisms are so constructed and operated as to require an undue amount of space and so as to be a source of possible accidental injury to an operator.

Now it is the object of ouil invention to provide mechanism of lthe above indicated characteristics which will be of a high degree-of eicienc'y in operation, simple in construction and of adjustment, economical of space and proof against accidental injury to an operator.

Having now indicated in a general way the nature and purpose of our invention, we will proceed to a detailed description thereof, with reference to the accompanying drawings, in which there is illustrated a preferred embodiment, and in which- Fig. l is a plan view .of a portion of a cigar bunch machine embodying our Vinvention.

Fig. 2 is a. side elevation, partly in section, of the subject of Fig. l.

Fig. '3 is a sectional `view on line S-f-, Fig. 2.

Fig. t is an enlarged cross-section on line M, Fig. l.

a indicates the frame of a cigar bunch m-achine on which is mounted a rolling table b; The rolling table is provided with longitudinal grooves c in the bottom of which are perforations affording communication with a box d, which is continuously connected to a source of suction through a pipe e. Adjacent one endb of the table is a take-up roller f for a rolling apron (not shown) adapted to be supported by the table: g indicates a rolling bar supported on a sliding carriage and adapted to actuate the apron to effect the application of the binder to the ller and roll the bunch. Adjacent. to the rolling table is a paster Iz, provided with a pasteapply-ing wheel z' adapted to be actuated lfor the application of paste to a binder positioned on the rolling table.

The mechanism for cutting or forming the binder is carried by a bracket projecting from an air box lc secured to the frame a and within which are two air chambers c, lc, .connected with a. source of suction through valves to be` hereinafter described. On the bracket is secured an outer hollow shell Z provided with a row of perforations mA and extending about a vertically positioned knife blade n. lVithin the knife blade is a hollow inner shell o the upper surface of which is perforated and attached by means of a screw to the upper end of a stem p, as shown in Fig. l. rIhe lower end of stem p rests upon the end of an adjustable pin u threaded in one arm of a pivoted lever c. The upper surface of the inner shell, While normally lying vflush with the edge of knife n', is adapted to be raised above and lowered beneath the cutting edge thereof and lfor this purpose the other arm of lever o is provided with a cam follower' adapted to follow .a cam surface w formed on the side of a cam disc t and normally arranged to maintain the lever at rest with the upper surface of the inner shell lying flush with the cutting edge of the knife, but having a low section and a high section which causes the lever o to be oscillated, resulting in raising or lowering the surface ofthe shell with respect to the knife edge.

Communication is afforded between the inner shell c and the Vouter shell Z through an aperture vin the knife blade and `they are in lOO . communication with air chamber 7c, comu munication between which and a source of toY ' cam groove formed in a cam disc 9.

knowntype, adapted to cooperate with theV knife blade n to eiect the cutting of a binder out Vof aleaf supported by shells o and fm. To the lower end of the shaft is secured a pinion 6,V adapted to mesh with a segmental gear 7, formed on one arm of a pivoted lever 8, the other arm of which is provided with a cam follower engaged in a the cam disc is revolved, the lever 8 is oscillated, causing the roller mechanism toV be oscillated back and forth over the knife blade, the inner Ashell being then below the edge ofthe knife. Y

The mechanism for transferring the binder from the cutting or forming mechanism, above described, to the rolling mechanism comprises a hollow vertical shaft 10 mounted in a stand 11 mounted on the frame a: and having secured to its upper end a horizontally extending arm 12, there being communication between the interiors of the shaft and arin. A hollow transfer shell 13.

the bottom of which is perforated, is rotatably secured at the free end of the arm and is in communication with the interior of the arm through a neck 14. Adjacent its upper end the shaft 10 is provided with a grooved collar 15 in which engage keys 16 formed on a bracket 17. A rod 18, which is slidably mounted on stand 11, is pivotally connected at its ends to thetransfer shell 13 and the bracket 17,'thereby providing a parallel motion for transfer shell 13. p

The lower end ofthe shaft is reduced and threaded foi-,the reception of a nut which serves to support an abutment 19 for one end of a spiral spring 20 through which the shaft passes and the other end of which bears on the frame. The lower end of the shaft rests on adjustable pin 21 in one arm of a, pivoted lever 22, the other arm of which is provided with a cam follower engaging a cam 23, by the action of which the shaft 10isy moved up vertically againstthe action of spring 20 which, when permitted by the cam, returns the shaft. A'segmental gear 2li is mounted on the shaft 10 adjacent its lower end and meshes with a segmental gear 25 on the end of a pivoted lever 26. The lever 26 is adapted to be oscillated by a link 27, one end of which is connected to lever 26 by means vWhen of a slot and pin connection and which is adapted to be koscillated by means of a cam disc 28, through a cam follower 29. Oscillation of lever 26 is transmitted to shaft 10, which results in' the swinging of arm 12- being turned on a vertical axis by means of the parallel motion including rod 18.

The interior of shaft 10 is connected to air box Ze through a passage 30, communication being controlled by a valve 31 adapted to be actuated by a pivoted lever 32, one arm of which engages ythe stem of the valve and the other arm of which is provided with a cam follower adapted to follow a cam surface 33, which oscillates the .lever to open the valve against the action of its spring, which closes it when the cam permits.

The operation of the device will, it is believed, be readily understood if it be premised that the rolling tablel is constantly under suction, the transfer shell 13 is placed under suction and the suction relieved by the'opening and closing of valve 31, and the inner shell o and outer shells Z yare placed under suction and suction relieved on both simultaneously by the opening and closing of valve y. The arm 12 and shell 13 are swung about the axis of the shaft l10 by the oscillation of lever 26 and they are raised and lowered vertically bythe oscillation of lever 22. The jaw 5 for the support of roller mechanism is swung' on the axis of its supporting shaft by the oscillation of lever 8.

The several cams adapted for the actuation of the several elements of the device are arranged so that the several elements are actuated in timed relationship as follows:

Vith suction on the shells Z and 0` and the two shells lying in the saine plane, an operator places a tobacco leaf over the knife blade, the roller mechanism is advanced and the inner shell depressed, resulting in the cutting out of a binder from the leaf. .fis the roller mechanism is retracted, the arm 12 has been swung to position'the transfer 13 over the inner shell, the transfer having been turned to align with the inner shell by the action of rod 18. Shaft `10 is then lowered resulting in lowering the shell 13. At the same time the inner shell 0 is raised above the knife and the binder presented to the underside of the transfer shell. Suction now goes off the inner and outer shells and on the transfer shell resulting in transference ofthe binder from the inner shell to the transfer shell.

The shaft 10 is then lifted, lifting the shell 13, and the inner shell returned to normal in plane with the outer shell Z. The arm is then swung in a horizontal plane to position the shell 13 over the rolling table, the shell being` turned to proper position by the action of rod 18. The shaft l0 is then lowered and the binder presented to the rolling table by the shell. Suction then goes off the shell and the suction on the rolling table causes a transference of the binder.

Having now fully described our invention, what we claim and desire to protect by Letters Patent is:

In a cigar bunch machine, the combination with a binder cutting device and a rolling table, of an arm mounted on a vertical pivot, means for the support-.of a binder pivotally mounted on said arnn means t-o swing` said arm in a horizontal plane, a link paralleling said arm and pivot-ally secured at one end to said support for a. binder and Xed means pivotally engaged with the other end ot said link whereby when said arm is swung said support will be turned through the medium of said link.

In testimony of which invention, We have hereunto set. our hands, at Philadelphia, Pennsylvania, on this 21st day ot' January, 1925.
