2 Claims.

` practice or skill to produce very superior cigarettes comparable with 'regular manufactured articles.

To this end it is proposed to provide a very simple device by means of which the proper quantity of tobacco for each cigarette is allocated regardless ofthe moisture in the tobacco.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more particularly described and claimed.

Two sheets of drawings accompany this speciiication as part thereof, in which like reference characters indicate like parts throughout.

Figure 1 is a perspective view of the assembled cigarette making apparatus.

Figure 2 is a vertical cross section through the tobacco allocating and transfer means.

Figure 3 is a vertical cross section taken on line 3 3 of Figure 2.

Figure 4 is a side elevation of the cigarette rolling device.

Figure 5 is a vertical cross section taken on Vune s-s of Figure 4.

Figure 6 is a fragmentary plan view of the transfer device in discharge relation to the rolling device.

In Figure 1 of the drawings is shown a convenient assembly of the improved cigarettemaking apparatus on the base I to which is secured the tobacco allocating device indicated generally by 2, a transfer device indicated generally by 3, and a rolling device indicated generally .by 4.

The allocating device 2 consists of a frame work formed from a sheet'of metal 5 bent to provide a table-like member having depending leg parts 6 5, the lower ends of which are out-turned to form feet I by means of which it can be secured to the base I. Portions of the legs 6 on either side of the feet 'I are turned inwardly to form bearings I i and the corners of the table 5 adjacent each leg are notched,v as at I5. A portion of one of the legs 6 adjacent the top is cut out in the form of a tongue and bent upwardly, as at l, andY this tongue 8 is cut out as at 9 to provide arpivot seat for a balancing tray I0, which is formed with a medial transverse compound ridge Ii by means of which one side of the balancing tray is elevated above the level of the other side,

23--23 joined by a rear wall 22.

side of the tray is provided with a slot I2 in which is slidably positioned a counterweight shown in the form of a small bolt I3, which can be adjusted with respect to the balancing ridge II, depending'upon the weight cigarette to be made. The size of cigarette is determined by the length of the apron 40, in conjunction with the width of space between the roller 38 and roller table 50. The sides of the lower half of the balancing tray are uptumed to form side anges I4. Two wires I'I are similarly bent into general U-form having their lower free ends in turned, as at I8, to seat in the sockets I5 formed on the legs 6 and the sides of these members i1 then engage the notches I5 at the corners of the top 5 thus positioning these members in rigid vertical position with respect to the table 5. The frame being hinged inthis manner it can be folded to put in container for shipment. The horizontal portions I8 of these U-members are depressed by means of return bends which provide oppositely disposed stays for the receiving pan 2 I which is formed preferably of sheet metal having its side edges upturned to form walls The forward endl of tray 2| is provided with an oriiice 24 from which depends a guiding lip having side walls 25". On the outer side of walls 23 are positioned spaced ridges 2l defining grooves adapted to receive the side stays 20 of one of the supporting Wires I'I by means of which the tray 2| can be adjustably secured with respect to the axis of the balancing tray I0 depending upon the condition of the tobacco at any particular time. Thus when the tobacco is quite moist and, therefore, heavier than ordinary, the tray 2I will be moved backward as far as necessary for proper tightness of cigarette. On the other hand, when the tobacco is unusually dry, tray 2l will be moved forward and intermediate slots may be provided for intermediate conditions if desired, the object being to provide a simple means for adjusting the point of deposit of tobacco which will be advanced on tray 2l and deposited on balancing tray I0 by lip 25 so that where the tobacco is very moist the pile deposited on balancing tray I0 will be closer the axis of the balancing pan while when the tobacco is quite dry it will be deposited farther out on the pan. In operation, the tobacco which is to be made into cigarettes will be initially deposited on tray 2| and then advanced by the nger of the operator, or any suitable small fork, to the opening 24. The tobacco thus deposited through opening 24 will in as shown in Figure 2. The elevated falling be deflected uniformly by lip 25 so that if- 3l beyond which the bottom 25 extends in the form of a tongue 28 extending the full width of the bottom 26. 'Ihe tongue 28 serves as a gauge so that when the tray 3 is positioned with the front edge of tongue 28 abutting the forward foot l of table 5, tobacco deposited by the tilting balance I will fall between the walls 29-29 of the scoop.

The cigarette roller 4 is of a type already generally known and comprises a bottom 32 formed with side flanges 33to which are pivoted, as at 36, the legs 35 of a U-shaped roller device, which legs are formed with enlargements 34 between which is pivoted a roller 38, as at 39. A generally U-shaped table 50 is secured to the bottom intermediate the side iianges 33-33 and a exible apron-40 is positioned over -the table 50, having its opposite ends removably secured by means of wires 42 passed through suitable hems and provided with hooked ends adapted to engage the side anges. Apron 4l) is of suiicient length to pass over the table D and the roller 38 with suiiicient slack to form a transverse pocket between the table and roller when the roller is in its left-hand position. The enlarged portions 34 of the roller support serve as side walls for the pocket which constitutes what may be considered as a receiving station of this roller device and is indicated generally by S. Tobacco is placed in this pocket and the roller then swung to the right, up and over table 5G, rolling the tobacco during the initial portion of the movement and wrapping same in a paper wrap positioned on top of the apron at the top of the table as the roller is still further advanced to the right. To properly position the cigarette Wrap with respect to apron 4U, a holder gauge 48 is provided, formed of a sheet of metal having an up-turned fiange 49 and its opposed edge wrapped about a `U- shaped wire 45, the ends of which are inturned as at 46 and pivoted in suitable orices in a bottom plate 55. This holder 48 is held normally in its vertical position by a spring 47, as indicated in Figure 5.

A portion of tobacco having been deposited in the transfer tray 3, the tray is positioned with the gauge flange 28 engaging by its ends the side walls 34-34 of the receiving station S of the cigarette roller and the tobacco is then deposited in this receiving station by emptying tobacco from tray into station Sand advancing same from the side walls where the longer iibers are predominant, the small particles falling to the bottom of station S centrally thereof and still retaining their position generally intermediate and under the long bers retarded by the converging walls 29-29. This arrangement can here be further emphasized by again spreading the tobacco in station S, movingVY the long fibers from the top out towards the sides 34 and pushing all the tobacco to a uniform depth in this pocket. The

cigarette wrap having been positioned, asindicated at W (Figure 4) where it is held by member 48, the roller carrier 31 is advanced to the right or clockwise, thus preliminarily rolling the tobacco in the receiving pocket until this roll of tobacco reaches the forward end of the wrap W whereupon the wrap is gradually rolled about the cigarette at which point the sides 34 of the roller carrier engage the arms of the U-member of the wrap holder and as the .roller carriage is further advanced to the right the wrap holder is advanced ahead of it.

By referring to'Figure 4, it will be noted that the table is eccentric with respect to the path of roller 38, the roller carriage being pivoted at 3S, so that as the roller is passed over table 5U, the clearance between the roller and the lefthand side of the table 50, as at 52, is relatively greater than the clearance between the table and the roller after the roller has passed over the cigarette wrap as indicated at 5 I.

With an apparatus such as illustrated and the successive operations carried out as suggested, very superior uniform cigarettes can be made by an amateur with entire satisfaction.

Various modifications in the precise structure and arrangement will readily suggest themselves to those skilled in the art but within the scope of the present invention as claimed.

Having thus fully described my invention, I claim:

1. In a cigarette making apparatus means for separating tobacco into portions of equal volume comprising a balancing pan formed with a medial transverse crimp to provide a pivoting surface f and a feeding platform positioned above and adjustable transversely with respect to the pivoting surface of the balancing pan, said platform having a discharge lip for feeding tobacco to a predetermined position on the balancing pan for each adjustment of said platform.

2. In cigarette making apparatus means for separating tobacco into portions of equal volume, comprising a balancing pan formed with a medial transverse, compound crimp to provide a pivoting surface and position the portions of the pan on opposite sides of said crimp above and below a horizontal plane intersecting said crimp, said portion above said plane having weight means adjustable toward and away from the pivoting surface, and a feeding platform positioned above and adjustable transversely with respect to the pivoting surface of the balancing pan, said platform having a discharge lip positioned above that portion of the balancing pan below the said horizontal plane.
