for applying gum or adhesive to one end of Patented June 30, 1931 UNITED STATES PATENT OFFICE FRANCIS X. MALOCSAY, OF UPPER SADDLE RIVER, NEW JERSEY, ASSIGNOR TO INTER- NATIONAL BANDING MACHINE COMPANY, A CORPORATION OF NEW YORK CIGAR BANDING MACHINE Application filed J une 16', 1925, Serial No. 37,464. Renewed November 29, 1930.

This invention relates generally to a cigar banding machine, and more particularly to a machine for applying bands to cigars, and has for its object to provide means whereby ungummed bands may be used in the magazine of the banding machine; to rapidly remove the bands from the band magazine, and arrange to apply gum thereon; to rapidly and accurately apply said bands to cigars and secure their overlapping ends together without damage or injury to the cigar or to the bands; and so to co-ordinate the mechanism that the gumming or adhesive mechanism will not function unless a band is in position to be moistened or have adhesive applied thereto. r

A further object of my invention is so to co-ordinate the mechanism as to reduce the number of operations necessary to apply the band and thereby increase the production and reduce the cost of applying the bands to the cigar.

A cigar is a very brittle and fragile article which can be easily crushed, and its wrapper injured and destroyed. I The band which is Wrapped around the cigar and not pasted thereon, is a fragile, flimsy paper article generally embossed, being small, of irregular shape and varying in length and Width. These cigar bands have to be handled in a very special way so that they will be Withdrawn one at a time from a pile of bands with accuracy, and with a mechanism that will not injure the band. The apparatus for applying the band must be of such a character as to permit bands of various sizes and shapes to be used. The band mechanism must be so organized as to accommodate bands the hand must work accurately and rapidly and must be so constructed that it will not apply gum except to a portion of the band and in no manner apply gum to the machine or mechanism, and mechanism must be devised so that the gumming or adhesive. mecha- Y nism will not function and be rendered ineffectual if no band is 1n position to receive gum or adhesive, and the mechanism for ap- The mechanism plying the band must be such as will not crush or injure the cigar.

The -foregoing are generally some of the objects of my invention which are accomplished by the machine which is the subject of this application.

A further object of my invention is the provision of means for gumming the band after it is removed from the pile of bands.

A further object of my invention is to provide means so that the gumming mechanism will be rendered ineffectual unless a band is in position to receive gum or adhesive.

A further object of my invention is the provision of means for utilizing ungummed bands and applying gum or adhesive there.- to. I have found that when gummed bands are used for banding cigars, that the bands have a tendency to adhere or stick or cake together, with the result that the operator must break the adhesion. This is usually accomplished by the operator taking a pile of bands and fanning the gummed end, and in this manner, break the adhesion. In many instances the bands, nevertheless, adhere together and two or more bands will consequently be removed from the pile of bands. I have found that by using ungummed bands this difficulty is overcome, and it is not necessary for the operator to fan the bands and that they will not adhere. Ungummed bands efiect a great saving in the manufacture in that the gumming operation is very difficult and complicated, requiring a great deal of labor. It has also been found that great difiiculty is eliminated in handling ungummed bands and that a greater'number of bands can be placed in the band magazine as both sides of the band are of the same thickness and hence the pile of bands on both ends is of the same level, which is not so when using gummed bands.

A further object of my invention is to provide improved means for separating the bands.

Another object of my invention is to provide a single means for separating and removing a band from the stack or pile of bands.

A further object of my invention is to construct a cigar banding machine having a single means, for separating and moving in a single cycle of operation, a band from a band magazine to a position where an adhesive or moisture is applied and thence to a banding position where the band is applied to a cigar.

Other objects and advantages will appear as the-nature of the improvements is better understood, the invention consisting substan tially in the novel arrangement and correlation of instrumentalities herein fully described, and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

Referring to the drawings, the machine comprises a frame A, a table B on which is located a row feed hopper D at the right, and a box supporting shelf M at the left (Fig. 1).

The operator seated in front of the machine removes the cigars from a box. Said cigars, when removed, are not disturbed from the position which they occupied in the box. As a result of the packing, the cigars assume various irregular shapes in cross-section. The removal of these cigars is accomplished by means of a tape or band and are taken by the operator and lowered into the row feed hopper D, which feeds the rows or layers starting from the bottom row, out upon the table B.

I will now give a more detailed description of the operating mechanism:

Dm'm'ng mechanism A motor 1 is mounted on a motor supporting base 2, pivoted at 3 on the rear of frame A, carries two pulleys, 1 and 5 respectively, on each end of its armature shaft. The pulley 4: by means of belt 6 drives the pulley 7, secured to a pump shaft 8, mounted in suitable bearing 9, 9 in frame A. Mounted on pump shaft 8, within frame A is an exhaust pump 10.

The pulley 5 by means of belt 11, drives pulley 12 secured to worm drive shaft 13, mounted in suitable bearings 14:, 14 in frame A. Secured to the free end of shaft 13 is a worm 15, meshing with a worm gear 16 mounted to rotate on a main cam shaft 17. (Figs. 2, 3 and 6).

Integral with one side of the worm gear 16 are the cams 18 and 19, on the opposite side of which is securely fastened the female law clutch plate 20, all of which run continuously. The cams 18and 19 operate the gum applying mechanism J, while the female clutch plate 20, when engaged'by the clutch dog 21 carried in the clutch 22 securely fastened upon the main cam shaft 17, drives said shaft, causing the entire mechanism to operate.

The worm gear 16, cams 18 and 19, and fe- 'male clutch plate 20, will hereinafter be referred to as the worm-gear-clutch-unit C.

Secured to main cam shaft 17 is a mitre gear 25, meshing with mitre gear 26, secured on a cross cam shaft 27, mounted in suitable bearings 2828 in frame Also secured to the cross cam shaft 27 is a spur gear 29, meshing with*a spur gear 30, secured on a cross cam shaft 31, mounted in suitable bearings 3232 in frame A.

When the clutchkdog 21 of clutch 22 is released it engages the clutch plate 20, of the operation, when the rest of the machine is not in operation.

Exhaust cal 0e Mounted within the frame A. on motor driven shaft 8 is a rotary exhaust pump 10 of the ordinary type, having intake and discharge ports. A pipe 33 connects the intake port and a cap 34 fastened to the valve body 35, secured on the side of frame A. Slidably mounted within the valve 35 is a vertically moving valve stem 36, to the lower end'of which is attached a spring 37. The other end of spring 37 is attached to a spring post 38, secured in the frame A, said spring 37 holding valve stem 36 in its lowermost position. The upper end of said valve stem 36 is pivotally connected by a link 39 to a bell crank 40, pivotally mounted on the stud 41. -The free end 42 of bell crank carries acam roller 43, actuated by cam 44, secured on main cam shaft 17. The extreme free end 45 of hell crank '40 extends around the side of frame A, the purpose of which is more fully described hereinafter.

The valve cap 34 attached to pipe connection 33 forms an 11., and has an elongated opening at its flanged end corresponding to a vertical slot 46, in the valve body 35.

A hole 47 drilled into one side of valve stem 36 travels within the limits of the vertical slot 46, (see Figs. 31 and 32) while a hole 48 drilled at a right angle to hole 47, and connecting therewith registers alternately with two holes 49 and 50, in valve body 35, said holes 49 and 50 having screwed therein the to the banding mechanism K, while the flexible tube 54, attached to hose nozzle 52, leads to a formed connection 55, to which is attached two flexible tubes 56 and 57. The flexible tube 56 leads to the band separator and conveyor F, while the flexible tube 57 leads to the emergency gum control H, hereinafter explained.

In order that the hand held by the exhaust to either the band applying mechanism K or on the band separator and conveyor F, may be instantly released when the exhaust is cut off by the action of valve stem 36, there are two small holes 58 and 59, drilled in and through valve stem 36. When valve stem 36 is raised cutting off the exhaust at hose nozzle 52, or on the band separator and conveyor F, and the emergency gum control H, the small hole 58 in valve stem registers with a small hole 60 drilled in valve body 35, allowing air to enter, thereby breaking the vacuum between the valve stem and the hand held on the combined band separator F. With the valve stem in this position the exhaust is on the banding mechanism K. When the valve stem 36 is lowered, cutting off exhaust on banding mechanism K, the small hole 59 in valve stem 36 registers with a small hole 61 as illustrated in Fig. 31, allowing air to enter, thus breaking the vacuum between the valve stem 36 and the banding mechanism K.

Emergency-gum-control The object of this device is to cause the adhesive mechanism not to function unless a band is in position ready to receive the adhesive, preventing gum from being applied to the band cushion or support.

The emergency gum control comprises a bracket 62 (Fig. 5) having a vertically disposed cylinder 63, enclosing a vertically moving piston 64. A spring keeps the piston 64 in its upward position. The flexible tube 57, connects the cylinder 63 with valve nozzfe 52 by means of the forked member 55. The upper end of piston 64 is pivotally connected to hell crank 66, pivotaly mounted on stud 67, secured in bracket 62. The free or upright end 68 of hell crank 66 is so positioned that in its normal or effective position it will check the downward movement of the swinging band cushion 69, of the gum applying mechanism J, preventing the said band cushion 69 from reaching its extreme downward or effective position, unless there is a band covering or closing the suction holes 7 Oof the band separator and conveyor F, in the following manner:

"With the machine in its normal or stop position the band separator and conveyor F is in its lowered or horizontal position, as shown in Fig. 24, the suction holes 70 below the stack of bands 71 with the exhaust cut off, the free or upright end 68 of the bell crank 66, in its normal or effective position, checking the
