MOBEHEAD PATTERSON, OF NEW YORK, N. Y., ASSIONOB TO AMERICAN IACHINE &

FOUNDBY COMPANY, A CORPORATION 0F NEW JERSEY INCLINED FEED' FOR CIGARETTE MACHINES Application led Hay 28,

v,This kinvention relates to al1-improvement 1n' feeds for continuous rod cigarette machmes, its main object being to provide forwarding means traveling in a direction at an acute angle to the direction of movement in which the tobacco falls. In this manner, the change in direction of the tobacco when it falls on and follows the forwarding means is made less with thc result that the natural `tendency of the tobacco to resist a sudden thereof instead of causing uncontrolled re- .bounding of the tobacco, particularly of the heavier tobacco shreds, such as is likely to occur when the tobacco sheds strike the forwarding means at right angles.

In the `present invention the cigarette paper strip or an endless belt is threaded through the feedtrough and can be inclined at the l proper angle to intercept the shower of tobacco by inclining the feed trough at the desired angle when the machine is started for production and returning it to its horizontal position upon stopping the machine. Thus, when the machine is cranked by Vhand for threading the cigarette paper strip and for adjustment of the partsl previous to starting, the tobacco falls on the stationary or slow moving cigarette paper strip'or endless belt at right angles and therefore has no forward inertia., while at production speed, when the trough has. been raised to a predetermined' angle corresponding with the velocity of the paper strip or endless belt, the forward inertia of the tobacco compensates for the inertia of the tobacco relative to the moving paper stripor endless belt. The trough may also be .inclined at a predetermined fixed angle in accordance with the velocity of the paper strip running therethrough.

In carrying the invention into ei'ect there is provided a cigarette machine feed chute having an open bottom inclined from the horizontal and adapted to confine tobacco falling therethrough ina shower, means traveling under the bottom of the chute and angularly intercepting the falling tobacco and forwarding it out of the range of action of the chute. In the best forms of construction contem- -plated the traveling means may include the cigarette paper strip or an endless belt. In the best forms of construction, also, there is provided a pivoted trough which may be automatically or manually adjusted to intion, therefore, is not to be restricted to the speclic construction shown and described.

Referrin now to Figs. 1, 2 and 3 of the drawings, t e tobacco T in the feed chute 10 4which has an open bottom inclined from the horizontal is adapted to confine the tobacco in a shower which falls on the cigarette paper strip P fed from a reel, not shown, throu h the feed trough 11 under the bottom of t e chute. The trou h 11 carries a projecting roller 12 for guiring the paper strip and is pivoted on screw studs 13 in a pedestal 14 attached to the frame 15 of the cigarette ma chine, and has side guards 16 attached to its cover strips 17 which guide the edges of the paper strip P. At the free end of the trough the side guards 16 are connected by a cross wall 18 which comes to lie against the end wall 19 of the feed chute 10 when the trough is raised into inclined position.

On a shaft 20, supported in vertical alignment with the studs 13 in pedestal 14,'is mounted a concave roller 21 on which turns a tape belt 22 guided thereto by a roller 23, this tape belt encircling the lower part of the paper strip P and propelling the same through the rod former 24 and subsequent parts of the cigarette machine in the direction of the arrow shown. To facilitate the turning of the paper from the inclined'to the horizontal position, a concave compression wheel 25 is mounted vertically above the studs 13 on a shaft 26 supported in pedestal 14. Spacers 27 on shaft 26 hold wheel 25 in alignment with roller 21 so that the tobacco on strip P must pass through the oval space between roller 21 and wheel 25 in all positions of trough 11, the paper being pressed down into tape 22 by the tobacco under the compression wheel at the delivery end of trough 11 while its edges are guided by the projecting points of the cover strips 17 as shown in Fig. 3.

Near its free end the trough 1l carries a gear segment 28 adapted to engage with a pinion 29 on shaft 30 supported in bearings 31 attached to frame 15. The shaft 30 is driven in one direction or the other by a worm wheel 32 'according to the turning direction of its worm 33 which is mounted on the shaft 34 of a reversible electric motor 35. The convex surface of segment 28, near its end, is provided with a groove 36 adapted to be engaged by the core 37 of a solenoid 38 When in its uppermost position, and with the core 39 of a solenoid 40 when in its lowermost position to lock it in these positions respectively. When approaching its lowermost position, the segment 28 compresses a spring 41 which serves as a buffer to the downward motion of the trough 11 and also has the purpose of raising the segment 28 into engagement with pinion 29 upon being released by the core 39 of solenoid 40 in the down position of the trough.

The motor 35, Fig. 1, is connected to the cutout 42 of an electric line circuit 43 through a two-point switch 44 formed by the lever 45 of the clutch shifting sleeve 46 on main shaft 47, the current flowin by way of wires 48, 49 and 50 through the orward winding of the motor when the clutch lever 45 is in the full vline in position von contact 44, and by the segment 28, and pulling core 37 away from stop 53 against which it is held by spring 54. T he core 37 then bears against the convex surface of segment 28 and, when trough 11 is in its uppermost position with segment and pinion just out of engagement, snaps into groove 36, thereby rlocking the trough in this position.

When the machine is stopped, the turning of lever 45 deenergizes the forward motor winding and solenoid 38, and energizcs the reverse winding and lower solenoid 40. The solenoid core '37 is thereby pulled back against stop 53 by spring 54 and the solenoid core 39 is pulled away from stop 55 by the action of solenoid 40 against the tension of spring 56. The weight of trough 11 will then bring the first tooth of segment 28 back into engagement with pinion 29 so that the reverse motion of motor 35, causing the clockwise rotation of pinion 29, will lower the trough until, after the passing of the last tooth of seg ment 28, the oint of core 39, guided by the tapered end of) the segment, snaps into groove 36 and locks the segment. In this position of the trough, shown in dotted lines, the buffer spring 41 is compressed, so that, upon the release of core 39 in restarting the machine, it will lift the last tooth of segment 28 back into engagement with pinion 29.

In the modification shown in Figs. 4, 5 and 6, the feed trough l1 carries an endless belt 57 made of linen or other suitable material which travels through the trough at the 1'equired speed and receives the tobacco charge from the feed chute. The belt 57 runs over guide roller 12 in bracket 58 and over concave driving pulley or roller 59 on shaft 60 which is supported in the lugs 61 by which the trough is pivoted on studs 62 and 63 in pedestal 64. On an extension of stud 62 is loosely mounted a gear 65 meshing with a gear 66 on shaft 60 and driven by a sprocket 67 connected by a chain 68 with sprocket 69 on a drive shaft 70; Directly below pivot studs 62, 63, in pedestal 64 is supported a shaft 7l on which is mounted the concave guide roller 21 for the tape belt 22, and the paper strip P is fed onto tape belt 22 over guide roller 72 from a reel, not shown. From Between the convex rollers 21 and 59 is' suspended the concave bridge piece 75 attached by brackets 76 to trough 11 so that the bridge 7 5 is in alignment with belt 57 and with the paper strip on tape 22 in all positions In Fig. 7 another modification of the ar-` 1 angement of the inclined paper feed trough is shown. Here, the feed trough 11 is stationarily mounted in its inclined position by a frame or pedestal 8() supported on the machine frame 15. The paper strip P is fed into the trough by. guide roller 12 and is propelled by the tape belt 22 running over rollers 21 and 23 and driven by tape wheel 81 on shaft l shower, of means traveling under the bottom of said chute and an ularly intercepting the falling tobacco and igorwarding it out of the range of action of said chute.
