OFFICE 1 ELBERON DOUGLAS SMITH, OF BROOKLYN, NEW YORK, ASSIGNOR TO AMERICAN MACHINE & FOUNDRY COMPANY, A CORPORATION OF NEW JERSEY CIGARETTE FEED TOBACCO COMPRESSOR Application filed 'Aagustfll), 1931. .Serial No. 558,370.

for compressing thetobacco showeredgfrom the feed chute of the tobacco. feed to appnp'ximately the size or cross-sectionof the tobaej core in the finished cigaretterodfthereby fa tobacco to the travelling cigarette paper strip in the forward direction at a speed equal to that of the latter, thereby preventing skidding between tobacco and paper. With this and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto appended.

Heretofo're, the tobacco stream was fed from a feed chutedirectly upon the surface of the-running paper strip, thereby striking the surface at right angles which, due to the inertia of the tobacco mass, caused a delay in its partaking of the motion of the paper with the result that, relative to the moving surface, the deposited tobacco moves backward for a short. distance, thereby disturbing thee-venness of the layer.

To overcome this inertia effect, the tobacco from the feed chute, by means of intermediate belts, is fed onto the paper strip with aforward speed equal to that of the strip so that there can be no relative motion between them.

The tobacco from the feed chute is fed upon an inclined forwarding belt the rough surface of which prevents any skidding of tobacco. The latter is carried on this belt beneath a compressor belt moving at the same speed and ip the same direction of the first belt and forming with the same a tapered space leading to the moving paper strip.-

The narrowing of the space so formed causes gradual compression of the tobacco stream to approximately its final size. thereby producing a uniform and homogeneous tobacco core and takinga corresponding amount of compreasion work off the rod former which folds the passing strip around the tobacco layer to form the cigarette rod, this relieving of the rod former being of great importance in high speed machines. The thus compressed stream of tobacco is fed onto the running paper strip at the same speed and in the direction of the latter and thus motion immediately.

In the accompanying drawing in which like characters of reference indicate the same or 'ke parts: Fig. :1 is a front elevation of the tobacco feed compressor with the front cover removed Fig. 2 is a sectional end elevation same, taken on line 22 of Fig. l;

Fig. 3 is a sectional end elevation taken on line 3-3 of Fig. 1; and

Fig. 4 is a sectional top View taken on line of the 44 of Fig. 8, showing the compressed tobacco massleaving the compressor and entering into the receiving tongue of the rod former.

In carrying the invention into elfect'there is provided a cigarette machine feed chute, means for continuously forwarding a cigarette paper strip, and mechanism under the bottom of said chute for angularly intercepting the tobacco showered therefrom and compressing'it to the approximate cross-section of the core of a cigarette rod and forwarding and delivering the compressed tobacco to the cigarette paper strip at an angle thereto. In the best forms of construction contemplated said mechanism includes atravelling tobacco forwarding belt having its upper-run arranged to angularly intercept the tobacco falling through the feed chute, and a compressor beltoperating to compress the tobacco on the upper run of said forwarding belt and travelling therewith to deliver the compressed. tobacco tothe cigarette paper strip at an angle thereto. These various means and parts my be widely varied within the restricted to the-specific construction shown and described.

partakes of its p Referring to Fig. 1, the cigarette feed tobacco compressor is mounted on a frame forming part of the main frame of the cigarette machine and carrying the pulleys 6 and 7 mounted on shafts 8 and 9, respectively, which are driven in opposite directions, shown by arrows, from the main drive of the machine. Pulley 6 drives. a comparatively short con'iprcssor belt 10 over idler rollers 11, 12 and 13 and belt tightener 14 which are supported from theframe 5. Pulley 7 drives a long forwarding belt 15, extending along substantially the entire length of the feed chute, over idler rollers 16, 17 and belt tightener 18 which are also supported from the frame 5. Between the idler rollers 11 and 1:2, and 1G and 17, respectively, the travelling belts 10 and run in the same direction forming between them a tapered pathway or space for compressing the tobacco stream T delivered upon the upper runs of belts 10 and 15 from a feed chute 19 which confines the tobacco falling therethrough in a shower. The tobacco is guided on its way to the belts 10 and 15 by a rear wall 20 fixed on the frame 5 and a ren'lovable front cover '21 pivoted on said frame, Fig. 2, while the lower part of the. conu ressor is equipped with tobacco side guides 22 and 23, Fig. 3. Since the guide 22 is secured to theframe 5 and connected to guide 23 by the shaft of the roller 13, the guide 23 is also supported from the guide Q2. 'The tobacco is gradually compressed between the lower run of the belt 10 and the upper run of the belt 15 to approximately the crosssection of the core of the finished cigarette, thus leaving the rod former of the machine free to perform only the final shaping of the cigarette rod.

The cigarette paper strip P is continuously fed. from a reel R over a guide roller 24, supporting plate 25, and a laterally adjustpaper guide 26 onto an endless traction tape 2'?" driven from the main drive of the machine and running over a small roller 28 placed on level with supporting plate 25. To provide for adjustment of the paper guide 526 it is mounted on a screw threaded into a bracket fixed on the frame 5 and underlying the lower run of the belt 15 behind the roller 28., whereby the cigarette paper strip may be laterally adjusted without stopping the machine, as shown in Figs. 2 and 3. The belts 1t} and 1.5 and the tape 27 are driven at a prcdetermined velocity so that the compressed tobacco stream T and the paper strip P have the same speed when coming together and when entering the tongue 28a of the rod former. in order to press the tobacco on the cigarette paper strip to prevent any tobacco from following the belt 10 when it leaves the tobacco stream T at roller 13. a thin guide plate 29 extending into tongue a is fastened to guide 22. Plate 29 is cut an angle 30 to prevent any tobacco which may project upwardly from being arrested thereby, the tobacco following the angle 30 and passing between plate and guide 23 into the rod former. Furthermore, the tongue extends sufficiently to engage the portion of belt 10 running over roller 13 to scrape ofl any tobacco which may adhere to the belt. The compressor is equipped with supporting plates 31, 32 and 33 for belt- 10, and with supporting plates 34 and for belt 15. These supporting plates are fixed to the frame 5 in position to properly support the respective runs of belts 10 and 15. To prevent auy tobacco or dust from accumulating upon the surfaces of pulleys (3 and 7 or of rollers 11, 12, 13, 14, 16, 17 and 18, each of the same is equipped with a scraper plate 36. In view of the foregoing a detailed descrip tion of the operation of thedevice is deemed unnecessary and omitted in the interest of brevity.
