KNIFE-SHIFTIN G ATTACHMENT FOR CIGARETTE AND CIGARETTE-SLEEV E MACHINES.
Application filed June 27, 1913.
To all 'LU/LOWL it may] concern Be it known that I, ERNST CURT Miinn BAUER, a citizen of the German Empire, residing in Dresden-Liibtau, in the Kingdom of Saxony, in said Empire, have invented certain new and useful Improvements in Knife-Shifting Attachments for Cigarette and Cigarette-Sleeve Machines, of which the following is a specification.
This invention relates to an improved knife-shifting attachment for cigarette and cigarette-sleeve machines.
In cigarette-machines, respectively cigarettes1eeve machines, in which the cigarettes and cigarette-sleeves are formed into a continuous strand or tube, it is necessary to shift the cutter-carriage constantly for the speed of the same during the cutting off of the cigarette or sleeve.
If it should be required to produce a change in the length of the cigarettes or sleeves to be cut off, it can only be obtained, when an equal number per unit of time is required, by changing the speed of move: ment of the cigarette-tube or sleeve. In connection with this requirement it is necessary to change the speed of the cutter-carriage in proportion therewith.
Different means have been proposed heretofore for regulating the speed of shifting the cutter-carriage, which, however, were so arranged that the uniform motion which is transmitted from the driving shaft is transmitted by means of interposed gearing, so as to produce thereby the shifting motion of the cutter-carriage.
The object of this invention'is to produce the same result, namely, the shifting motion of the cuttercarriage proportionately with the speed of the cigarette-strand or sleeve without the use of expensive variable mechanical means; and for this purpose the invention consists of a knife-shifting attachment which comprises two double levers which control the motion of the cutter-carriage from the driving shaft by means of an inclined cam in such a manner that the double levers, which move in side-contact with the steering cam, act sidewise on the cuttercarriage by means of rollers at the forward-end of the double motion-transmitting levers, which rollers are capable of adjustment for controlling different speeds of the cutter-carriage.
Specification of Letters Patent.
Patented July 27; 1915. Serial No. 776,035.
In the accompanying drawing means are shown for this purpose, in which F gure 1 represents a diagram for illustrating the shifting motion of the cutter- CELI'IIHQQ, Fig. 2 is a side elevation. of the mechanism for controlling the speed of the cutter-carriage, partly in section, Fig. 3 is a planv1ew of Fig. 2, with the cutter-carriage removed therefrom for greater clearne ss, Fig. .l is a vertical transverse section online 4PL, Fig. 3, and Fig. 5 is a detail section of one of the contact-rollers at the rear-end of the double shifting levers by which oscillatmg motionis imparted tothe double levers and laterally-shifting motion to the cutter carriage.
Similar letters of reference indicate corresponding parts throughout the different figures of the drawing.
Referring to the drawing, and more espe cially to Fig. 1, which is intended to show the principle of the cutter-carriage motion, (t represents the driving shaft and b a curved cam applied on the same from which, by means of antifriction rollers c, the two double-armed levers (Z are operated. Each lever (Z turns on a fixed fulcrum and presses against an antifriction-rolle'r 7 which is applied to'the cutter carriage and which is laterally movable in the direction of the double arrow shown in Fig. 1. By the curved cam in the double-armed levers d are placed into the position shown lIi dotted lines. During the shifting motion the aiitifriction-rollers fon the cutter-carriagemove through an angle al The antifrictioii-rollers f are applied to the cutter-carriage, but adjustable on the same, so that they ca nbe placed nearer to or farther away from the fulcra c. When the rollers f are shifted, for instance, into the position y, then they move during the uniform unchanged oscillation of the double-armed lever 03 through an angle d which is much smaller than the angle (Z For both movements the cuttercarriage requires the same time, from which it follows that the cutter-carriage has to be moved quicker when it is shifted through the angle d than when it is shifted through the angle 0Z For obtaining any desired shifting speed of the cutter-carriage, it is only necessary to adjust the rollers f on the cutter-carriage in proportion therewith.
The rollers c of the double-armed levers d move over the sides of the curved cam b on the driving shaft a. The shafts m of the rollers are supported in slotted eyes or sleeves of the double-armed levers d and are adjustable freely therein, The rollers 0 are held in contact with the side-walls of the curved :cam and adjusted thereto by means of set-screws Z, shown in Fig. 5, by which a side-pressure is exerted on the shafts m of the rollers c. The clamping of the roller-- shafts in their proper position is then accomplished by sorew-nuts 0. Through these adjustments, rollers 0 can be laterally shifted with respect to the faces of the cam b, so as to always contact with said faces, the distance of these rollersc from the pivot of the levers cl always remainingconstant.
The free forward-ends of the doublearmed levers cl act on the rollers f, which are supported on a slide-plate 9 that is guided in ways at the underside of the cutter-carriage, and which is shiftable in the supporting plate hof the same, as shown in Fig. 4. The shifting motion is accomplished by means of a spindle i, the threaded portion of which is engaged by a screwnut 70 that is supported in the frame of the cutter-carriage. By turning the spindle 2', the antifricti0n-rollers f are either moved toward or away from the fulcra e of the double-armed levers d, since these rollers f are moved along with the slide-plateg from the fulcra 6, so that these rollers f contact with and are moved by port-ions of the levers d at any desired distance from the fulcra e.
On the cutter-carriage h is supported a standard 77, to which the angular knife-lever is fulcrumed, which is constructed in the usual manner, and whose rear-arm engages aneccentric cam-portion]; on the steering cam 6, while the opposite forward-end carries the disk-shaped knife 29 that serves to cut oil" the required individual cigarettes fromthe strands or tubes. The oscillating motion of the cutter-carrying lever is accomplished in the well-known manner and forms no part of this invention.
I claim:
1. A paper-cutting attachment for cigarette or cigarette-sleeve machines, which comprises a laterally-shiftable cutter-carriage, antifriction-r0llers on the same, means for shifting the rollers in longitudinal direction on the cutter-carriage, fulcrumed double-armed levers contacting with said rollers, a driving shaft, and a curved cam on said shaft for engagement with the rearends of the double-armed levers.

8. A paper-cutting attachment for cigarette or cigarette-sleeve machines, comprising a laterally-shiftable cutter-carriage, antifriction-rollers on the same, a slide-plate guided on said carriage, a screw-nut in said slide-plate, a spindle for engaging said screw-nut and shifting said slide-plate, fulcrumed and laterally-oscillating doublearmed levers engaging said antifrictionrollers, antifriction-rollers at the opposite ends of the double-armed levers, a driving shaft, a curved cam on said shaft the sides of which engage said rear antifriction-rollers, and an eccentric cam-portion on said curved cam actuating the cutter-lever.
