in most finishing works.The simplest beetle consists of a strong frame,supporting a large roller upon which the goodsto be treated are rolled, above are placed twentyeight fallers, see fig. 96, p. 247, these are eachfurnished in the middle with »noses« or projectionsand lifted, by the cams of the revolving shaft:this shaft is driven by side-gearing and connectedwith the motive power of the machine, as will beunderstood by fig. 97. These cams are so disposed that each fallergives four blows for each turn of the shaft onwhich the cams are fixed. When the beetle was introduced, the beamor large bowl, on which the fabric is rolled wasworked by hand. It is now driven by a specialarrangement, the details of which are given infig. 97. The speed of this beam is so calculatedthat for each revolution the goods are beetled byall the fallers. Subsequently two beams were used: the beetlesworked on one whilst the next lot of goods werebeing rolled on the other. MACHINES EMPLOYED IN FINISHING. 247

248 FINISHING IX GENERAL. In the new beetles which work much morerapidly, this arrangement has been modified, onthe lower part of the machine a sort of moveabledisc with notches has been placed; this disc orrather these discs (for there is one at each endto support the cloth beam) are moveable and arenotched so as to place the three rollers at thesame time; the middle roller on which the beetleacts; the roller on the outside or behind themachine is then the one which has already beenin work and which can be unrolled ; and the frontone on which the goods are prepared during theworking of the machine. The operation on the middle roller beingfinished, the discs are turned — the first rollerbecomes the second, the second the third andanother is placed in front, to be prepared. Thisarrangement allows a continuous action of themachine so that the pieces can be taken awayand replaced without stoppages or interruption ofthe work. In the ordinary beetle the fallers being ofvery thick, hard c
