ROM CIGARETTE-MAKING Application led March 31, 1924. Serial No. 703,303.

To all 'willem t may concern.:

Be it known that I, LOUIS PAUL GRAUP- NER, a subject of the Republic of Germany, residing at Pennricherstrasse 23, Dresden- A, Germany, have invented certain new and useful Improvements in Means for De? livering and Sorting Cigarettes from Cigarette-Making Machines, of which the following is a specification.

In the more recent exceedingly high speed rod or rope-forming cigarette machines the cigarettes leaving their groove and already separated from the rod are not released with suihcient reliability from the rod if left to themselves to fall freely and be led away by inclined faces, feed drums or the like to the delivery outlet. This drawback is not overcome by allowing the cigarettes to drop into receiving pockets or the like arranged on an endless band or the like moving in the direction of the rod with a speed which is greater than the speed of the rod. As a result the cigarettes are entrained by friction but this friction according to experience is not sufficient to ensure the release of the cigarettes from the rod at high speeds of the rod. The cigarettes therefore must be positively seized and led away by clamping jaws or the like. Y

The present invention consists in the arrangement at regular intervals apart on the periphery of a disclike continuously rotating carrier (the peripheral speed of which exceeds the speed of the rod) of pairs of positively actuated clamping jaws in such manner that each cigarette leaving the groove is gripped by a pair of clamping jaws as they are closing, which is entrained therewith and led to a sliding surface over which thepair of clamping jaws open and release the cigarette, two successive sliding surfaces being provided and the control of the clamping jaws being such that the cigarettes carried thereby are alternately deposited on the first, and then on the second sliding surface.

The new device is illustrated in the accompanying drawing in Fig. 1 in side elevation and in Fig. 2 in vertical section on the line 2-2 of F Referring to fitted with 1s secured a disc with the shaft 2.

On the perip intervals apart of opposed bell crank levers pivot about th disc. projecting over carry opposed clampingjaws 8 resilient material such as rubpreferably of ber or the like.

a driving mounted 1n bearings 3 The ends the drawing, on a shaft 2 bevel pinion which is4 on the machine frame 4 which rotates continuously Oneach bearing 3 concentrically of the shaft 2 is mounte d a cam disc 9 i. e., on both sides of the carrier disc l is located a cam disc. and 11 axially another.

Each cam disc has two cam faces 10- disposed withrespect to one The pairs of clampingjaws are divided into two groups.

The one group consisting of the first, third and fifth pa1r of clamping jaws is actuated by the cam l() and the second ond, fourth, and sixtl group consisting of the seci pairs 0f clamping jaws is actuated by the cam 11.

On the free ends 5 are fitted rollers springs 13 are the cam faces 1 of the bell crank levers 12 which by means of pressed on the periphery of 0 or 1l. The cam faces are so arranged that on rotation of the carrier disc 4 each at the moment jected suiiicicnt and rests on the the disc rotates ceeding the speed cigarette gripped released from the is entrained by pair of clamping jaws is closed by the movement of the bell crank lever 12 when the cigarette Z is proly far from the groove A periphery of the disc 4. As with a peripheral speed exof the cigarette rod the by the clamping jaws is rod with certainty. It

the jaws and released when over an inclined surface 14, if the pair of jaws is actuated by the outer cam faces 11 the drop in the cam groove at 15 causing the separation of the clamping jaws 8. The inclined surface 1 4 is disposed tangentially of the disc 4 in such manner that the cigarette entrained bythe clamping jaws may pass straight through the slit between the outer end andthe edsge ofthe disc 4. When now the clamping jaws are separated the cigarette is dropped on the inclined surface disposed directly beneath the pair of clamping jaws the acceleration ensuring the downward movement over the inclined surface. This inclined surface inclines also slightly to one side so that the cigarette will roll down transversely of the plane of the disc on to the endless band 16.

When the cigarette, however, is gripped by a pair of clamping jaws actuated by the inner cam faces 10 the clamping jaws are opened when the depression 17 in the cam 10 is reached so that this cigarette drops on the new device gripping means the second inclined surface 18 located behind the first inclined surface and also disposed tangentially of the periphery of the disc 4. This second inclined face is also inclined slightly to one side so that the cigarette will roll down thereon transversely of the disc on to the endless band 16.

As the pair of clamping jaws are alternately opened at 15 and 17 tlie cigarettes are deposited on the band 16 in two positions in such manner that only those cigarettes having similarly directed mouth piece ends arrive at each delivery outlet.

As the high speed rod-forming cigarette machines deliver so many cigarettes at the two outlets that the workers at each delivery outlet are unable to remove the cigarettes as they arrive there may be provided with four delivery outlets.

Having now particularly described and ascertained the nature of my said invention and in what manner the saine is to be performed, I declare that what I claim is 1. A device for delivering cigarettes from a rod forming cigarette machine, comprising a continuously revolving body, means on and revolving with said body 'capable of periodically gripping a cigarette when brought into the path of the cigarette rod, a sliding surface in close proximity to the periphery of said body and means for causing the release of the cigarette from said the instant it arrives close to said sliding surface.

2. A device for delivering cigarettes from a rod forming cigarette machine, comprising a continuously revolving body having a peripheral speed exceeding that of the cigarette rod, means on said body capable ofY periodically gripping a cigarette when brought into the path of the cigarette rod,

an inclined surface in close proximity and tangential to the periphery of said body and means for causing the release of the cigarette from said grippin means the instant it arrives close to said inclined surface.

3. A device for delivering cigarettes from 05 a rod forming cigarette machine, comprising a continuously revolving body, pairs of gripping jaws carried by said body, means for closing said jaws to grip a cigarette when brought into the path of the cigarette rod, a sliding surface in close roximit and tangential to the periphery of) said bo y and means for opening said jaws to release the cigarette the instant it arrives close to said sliding surface. f.

4. A device for delivering cigarettes from a rod forming cigarette machine, comprising a continuously revolving body, cam controlled pairs of gripping jaws carried by said body and adapted to close and grip a cigarette when brought into the path of the cigarette rod, and an inclined surface in close proximity tosaid body, said jaws being adapted to open and release the cigarette the instant it arrives close to said surface.

5. A device for delivering and sorting cigarettes from a rod forming cigarette machine, comprising a revolving body, two sets of pairs of gripping jaws carried by said body, cams adapted to alternately control the operation of said two sets of jaws and two inclined surfaces arranged in close proximity to the periphery of said body, said sets of jaws being adapted to alternately close and grip cigarettes when brought into the path of the cigarette rod and to open and release the cigarettes, when arliving close to said inclined surfaces.
