device is held by means of a mechanical device in a position of apparent rest in relation-Y-to' an observation post incorporated "with the control ofa' turning device so that the operation of the'turning device can'be effected with certainty, notwithstanding the continuous movement of'the cigarettes.

In the preferred form the mechanical device comprises a" frame having anaperture therein through which the cigarettes are observed andan' operating appliance in'the frame'forenabling the turning of any desired cigarette seen through the aperture, said frame b eingladaptedQto move forward simultaneously with'thecigarettes and to return after a certain movement to "its original position. Y j

The appended drawings show by way' of examplea constructional form of the invention and Fig. 1 isafdiagrammatic sideview ofthe device.

Fig: 2zis a plan of the righthand part of F ig; his a section through 1 on the line A B. v I

Fig.4 is a. side, view of one part taken to be packed are conveyed the examples shown, consists of-a chain moving at a uniform speed. The links 10 of this chain are held together. by pins 11. 4

The links10 are provided with grooves 12, in" which the cigarettes 13' lie in an oblique position. The-grooves 12 have raised edges indicated by 14,-Fig;i1, against which the cigarettes rest. At suitableplacesfalong the line of travel one. or 'morenstops 15 are placed, these being vertically movable .up

and" down in guides 16, and so placedthat tent ofeight cigarettes.

when'in' the upward position they engage the cigarette as it movesalong, straightening. it and giving it a turn of 180.

Above the conveying'device 10, 11 for; the

cigarettes 13 a frame26 is provided, this frame being movable to and fro in thesame direction as the conveyor "device. Insthe middle of the frame is an aperture 26 through which a certain number of .cigarettesin the actual example eight, are visible. .The' frame moves forward at "the same speedasthe cigarettes themselves. "For this purposethe chain is. best provided atjsu'itable intervals, that is tofsay at each eighth link, with vertically movable pins (27.

These pins are controlled by f guides 28, 28 'insuch mannerthat when the frame 26 is required .to'start moving with the cigarettes,

as shown at the right -hand stop. 27 1,. they are raised upward. Theyth'en come up against the frame 26', and as they are held in the upward position, and move forward rettes' "through :its; aperture, whilst those lying further"; forward or, backs-on 'the conorig'inal application filed July 1', 1929, Serial No.;37 5 264, and in Germany May 23, 19278.. ,Divided. and

with the chain, they carry thefframealong at the same speed. The frame consequently shows always the same number of cigaveyor remain concealed. As soon as the stop 27 leaves the track28, and passes on to -the guide track28 it drops .into'tlie position. shown to the'left of Fig.'- 1 thereby releasing. the fframe'26, which by .means of springs, or, as shown in the example illustrated, weights 29 attached to cords 3 1--run 'ning on pulleys '30, can be. brought back into its. original position, where it comes up I against the next stop. 27 that has 'meanwliile been raised into the workingposition. and is cigarettes 13, visible through the aperture in the frame'26, therefore remain withoutmomechanism has moved'forward tothe ex- On the frame 26' eight keys 83 are I placed and each ofthese keys is adapted torelease the turning device. FQIitlllS purpose the ready to carry it forward again. .The eight the positions shown in Fi they pass by the free end of keys 33 are connected to electric circuits 35 35 etc. which are closed by pressure on the keys. The wires 35 35 and so on are jointly connected to one pole of a battery 36, the other pole of the battery being connected to a return wire. Each of the wires 35 35 etc.'leads to a roller or rubbing con- .tact 37 made of conductor material which is placed at the periphery of a revolving disc 36 driven by any form of power.

'There' are eight of these contacts working on the same axis and each one of them contacts with a slip ring 38 on the periphery of the disc 36.

lVithin the disc 36 are a number of electromagnets39, Fig. 3, in the present instance 24 altogether, that is to say three times as many as the number of push keys. The number of electromagnets being three times as large as the number of wires 35 35 and so on, the slip rings 38 are subdivided into three parts disposed around: the periphery V of the disc 36. Each one of the electromagnets 39 is connected by a conductor 40 to one of the eight slip rings 38. Two other discs, 41 and 42 are permanently connected to disc 36. Disc 41, which is of smaller diameter than 36 and'42, the latter preferably being equal, has on its periphery a coating of conductor material 43, connected by wires 44 with the adjacent ends of the magnet wind- .ings of all the electromagnets 39. In contactwith the coating 43 is a roller or rubbing contact 45, connected to the return Wire 35 of the electric circuit. v

In the disc 42 are longitudinally 'slidable magnet armatures 46 placed opposite to the electromagnets on disc 36, so that these armatures 46 are likewise 24 in number. The armatures 46 are generally arranged in 3, so that as an elbow lever 48 connected to the stop 15 of the turning device they hold the lever in such a position that the stop 15 of the turning device does not project into the path of travel of the cigarettes. When, however, the circuit of one of the electromagnets 39 is closed by pressing down the appropriate key 33, the respective armature 46 is attracted, so that on the subsequent passage of the armature 46 the lever 48 is released and is moved by the action of a spring 50 into such aposition that the stop 15 is in the raised position causing it to comeup against the cigarettes 13 as 1t moves forward and to give it a turn .of 180. The speed of rotation of discs 36 and 42 is so calculated that the passage of the attracted armature 46, and consequently the release of lever 48 shall occur at the moment inwhichtheparticular cigarettes 13,v the incorrect position of which gave cause for pressing down the key 33 and thereby closing the circuit, has arrived in front of the stop 15 of the turning device,

so that in every case it is the right cigarette that is turned.

.For the purpose of effecting the return movement of the attracted armature 40,

there is placed by the side of disc 42 an inclined surface 51 (Fig. 4) which has effect, as disc 42 continues to rotate, of pushing the armatures 42 back into the position shown in Fig. 3.

The scope of the inventionis not limited ing an aperture therein through which the cigarettes are observed; and on operating appliance in the frame for enabling the turning of any desired cigarette seen through the aperture, said frame being adapted to move with the cigarettes.
