Abstract: 14,126. Fell, J. C., [Fackler, G. W.]. Aug. 7. Parcelling cigarettes.-A machine shown in vertical section in Fig. 2 takes cigarettes from a stationary hopper, and places a definite number in a hollow mandrel 1 of thin metal, round which a sheet of paper is folded with a pasted edge ; the paper is closed over one end of the mandrel by folding and pasting, and the cigarettes pushed from the mandrel, with the paper, which is then folded and pasted at the other end of the parcel, forming a package. Many parts of the machine are driven directly by links and levers engaging cam-grooves on the sides of discs on shafts g, j, geared to a driving-shaft q ; rack gearing is interposed in some cases. The cigarette hopper (not shown) is flat and slightly wider than the length of the cigarettes, but the lower part of one side is hinged and pressed inward by a spring, to bear on the ends of the cigarettes, and retain them except when this part is moved outward, periodically. Below the hinged part an enlargement of the hopper receives some loose cigarettes. Below the hopper is a horizontally-reciprocating set of compartments 3, with horizontal extensions 77 to support the loose cigarettes. These compartments are formed by partitions carried by separate horizontal slides, which are connected by pivoted blocks to a transverse grooved lever, and the partitions are intermittently slightly separated to allow the cigarettes to drop, by unequal reciprocation of the sliders. The partitions may be inclined, to hold the cigarettes in position to pack closely together in a hexagonal package, as shown in Fig. 29. While the partitions are closed together, the proper number of cigarettes is pressed endways from between them by a gang of drivers into a forming-receptacle. This has a movable side and top, which are closed to definite positions while the receptacle slides from behind the partitions 3 before the fixed hollow mandrel 1. Another driver pushes the cigarettes from the receptacle into the mandrel, and afterwards from the mandrel into a stationary holder, which has a rising and falling clamping top. The sheets of paper are fed separately by continuouslyrotating rollers 24 and a horizontally-reciprocating pusher, each sheet being thus delivered on a mould 12, below the mandrel. The mould then rises, and the sheet is clamped by a spring-supported part of it, against the mandrel. While the sheet is so held, one edge of it, resting on a spring-supported lip, is coated with paste by a roller 36, which is carried by a lever 37 on a horizontal slider 38 and is also controlled by a stationary cam 40. The roller 36 normally stands in the position shown, and gears with wheels by which its surface is moved oppositely to that of a feeding-roller 31, below a paste reservoir 30. The mould 12 rises further, fitting the sheet to the underside of the mandrel 1. Two 'plates then move horizontally against one side of and over the mould, laying the unpasted edge of the paper thereon, after which a roller 61, carried by links 62 on a lever 63, passes over the mould, laying the pasted edge, while the two plates withdraw. Narrow projections on the upper plate temporarily support the pasted edge, without removing much paste from it. End folders operate on the end of a package on the mandrel, and simultaneously on the open end of a preceding package held in the stationary holder. Two of the end folders are centrally fixed on vertical sliders 123, 133, the upper one descending and rising before the lower one acts. The upper central folder 50 also has a horizontal surface, previously coated with paste by the roller 36, which in moving across it is caused to rotate oppositely by gearing with a stationary rack 49 ; this surface descends on the lower inner surfaces of the ends of the two papers, and coats them. Each vertical slider 123, 133 is linked to levers 120, 135, carrying pairs of corner folders 117, the arrangement being such that these act before the central folders. Plates between the upper corner folders 117 direct the paper property before them. When the lower central folder rises, it closes the pasted parts on the previously-folded parts. When this folder afterwards descends, it leaves spring-pressed fingers holding up the pasted folds until a rear presser moves the preceding package forward against that in the mandrel. Both packets are then moved rearward, the finished one passing over a vertical delivery way, into which it is pushed by a descending presser ; in rising, this presser leaves the rear end of the stationary holder closed for a time by a shutter.
