Abstract: 7328. Du Brul, N. March 28, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883], Cigars.-Relates to cigar-bunching machines of the type shown in Fig. 1, and comprising a tobacco hopper 1, a matrix slide 5 by which the filler is taken from the hopper in measured quantities and presented above the rolling table or apron 17, a plunger 18 and co-operating follower by which the filler is discharged from the matrix 9 into a pocket 16 formed by the rolling-apron, levers 61 to operate the rolling-apron to form the bunch, a bunch carrier 23 into which the apron discharges, a mould-carrier 29 supporting a mould over which the bunch is presented by the bunch carrier 23 and moving the mould intermittently to bring its several matrices successively into position to receive a bunch from the bunch carrier, and a plunger 21 for discharging the bunches from the bunch-carrier into the mould. The invention consists, firstly. as shown in Fig. 5, in providing means whereby each charge of tobacco as it is measured in the matrix 9 of the sliding plate 5 is subjected to a current of air through it, to remove the dust and finer particles therefrom. It is preferred to continue the air suction during the period in which the matrix 9 advances to discharge its tobacco, in order to clean the parts beneath the hopper 1 of the dust and particles accumulating there. A chamber 41 is formed in the base, and is connected by a passage 48 to an outlet 49 leading to any source of air suction. The upper part of this chamber is formed by a plate 42, which is perforated at the part 43, which lies beneath the matrix 9, when the latter is at or near its inner limit, and through these perforations a current of air is drawn so long as the matrix is in this position. In order to induce an air current beneath the other parts during the advance of the matrix slide 5, the plate 42 has an opening 44 through which a current of air is drawn from the hollowed-out part 45 of the slide 5, the air entering at 46 at the rear end of the slide. The invention consists, secondly, in giving to the rolling- apron 17 a greater range of rolling than is usual. This is effected by employing a long rolling-lever 61, fulcrumed near the bottom of the machine, and operated by a secondary lever 67, which is actuated by the usual cam 66. The invention consists, thirdly, in arranging the bunch-carrier 23 so that the bunch may be deposited at different relative positions in the carrier, and consequently reach different relative positions in the mould. The bunch-carrier 23, which is preferably provided with a spring jaw, is mounted on a sliding track 50, extending beneath the discharge end of the apron 17, and is reciprocated by a lever 51 fulcrumed at 52 and having a stud 53 engaging in the groove of the cam 54. The lever 51 is connected to the carrier 23 by a crank 55, and by adjusting the connecting-pin 57 between these two parts the desired object is effected. Direct means for slackening and tightening the apron 17 are provided. This is effected by the lever 22, which is fulcrumed at 22<a> and supports the rear end of the apron. It is moved backwards and forwards by the double cam 22<b>, which is so timed as to coordinate the movements of the apron with those of the plunger 18 and the rolling-lever 61.
