Specification of Letters Patent. Application filed February 27, 1905.

Patented Aug. 10, 1909.

Serial no. 247,607.

To all whom it may concern: Be it known that I, LEONARD LINnnLor, a subject of Emperor of Russia, and resident of Helsingfors, Finland, Russia, have invented new and useful Improvements in achines for Filling hacco, of which the following is a specification, reference being had to the drawings accompanying and forming parthereof.

This invention relates to improvements in machines for automatically filling cigarette shells with tobacco. j In such machines heretofore known there is commonly used a number of stationary filling pipes on which the shells are placed to receive the string of tobacco and the mechanism feeding the shells to the said filling pipes whole process of placing the shells onto the filling pipes, filling the shells and pushing off the same from the filling pipes, much time being thereby wasted.

The object of the present invention is to reduce the time required foraccomplishi-ng the said process and thus ciency of the machines.

The invention consists, chiefly, in the provision of a rotary disk, an endless belt, chain, or the like for supporting the filling pipes and having a continuous or step-by-step motion. The shells may be delivered to the machine either directly .by, a shellmaking machine or by means of rotary drum, an endless belt, or the like, having in well known manner grooves to receive the shells and moving together with the said filling pipes. For leading the tobacco, which is fed in any suitable or well known manner to the machine in the shape of a continuous string or suitable portions thereof, to the filling pipes are used and to the latter is, in the case the filling pipes are moving continually, imparted by suitable means an intermittent motion in such manner that the said mouth-piece vor mouth-pieces will accompany the filling pipes, while the tobacco is fed into a shell and thereupon be rapidly brought back to the next filling pipe or pipes.

The devices forming he tobacco into a string or portions thereof form no part of the present invention and are, therefore, neither shown nor described.

In the accompanying drawing I have shown an apparatus embodying my invention.

Cigarette-Shells with Tomust be stopped during the to increase the eifi one or more mouth-pieces Figure 1 shows an elevation of the apparatus and Fig. 2 a top-view of the same. To the base plate '1 are secured brackets 2, 3 andl in which are journaled two shafts 5 and 6. The main shaft 5 rotates in the direction of the arrow in Fig. 1. From the said main shaft 5 the movement is transmitted by means of the bevel wheels 7 and 8 to a shaft 9 and therefrom by means of a worm 10 and worm-wheel 11 to the said shaft 6, the latter being rotated in the direction of the arrow. T o the shaft 6 is secured adrum 12 having on its circumference grooves 13 to receive the cigarette shells. The bevel wheels 7 and 8 and the worm- .wheel 11 are of such size that the drum 12 ateach revolution of the shaft 5 will be rotated through an angle corresponding to the distancebetween two adjacent grooves. ()n the shaft 6 is further provided a disk 14L supporting obliquely cut off filling pipes 15 the number of which corresponds to the number of grooves 13 of the drum 12 and each of which is placed opposite one of the said grooves. To the base plate 1 is secured a bar 16 supporting a holder 17 for the shells. The bracket 4 is provided with an upwardly projecting arm 18 to which by.

means of screws 20 or the like is secured a curved plate 19. The edge of the latter facing the filling pipes 15 is inclined as shown in Fig. 2 and the object of the same is to push the shells onto the filling pipes. In order that the plate 19 may be adjusted in accordance with the' length of the shells used the holes forthe said screws 20 may be made oblong as shown in Fig. 2. However, the said plate 19 may be made adjustable in any other convenient manner as will be easily understood; To the said arm 18 and to another arm 21 of the bracket 1 is secured a protecting screen 22 inclosing a part of the drum and adapted to prevent the cigarettes from dropping out too easily from the grooves 13 of the drum.

A characteristic part of the apparatus is a two-armed lever 23 journaled on the shaft 6 and being prevented from sliding on thethan the filling pipes 15. The said holes 26 I and 28 are placed atexactly the same radial distance from the shaft 6 as the filling pipes.

The distance between the holes 26 and 28 is twice as great as the distance between two adjacent filling tubes. On account thereof the said two holes will always simultaneously be opposite two ofthe filling tubes (see Fig. 2). s mentioned above the disk 14 rotates from the left to the right through an angle corresponding to the distance be tween two adjacent filling pipes while the shaft 5 makes one revolution. The shape of I the cam-disk 25 is such that the lever 23 will at first be rapidly turned backward to the left from the position shown in Fig. 2 and exactly as far as to bring the holes 26 and 28 opposite the next filling pipes to the left whereuponthe lever will be turned at lower speed from the left to the right exactly following the movement of the drum l2 and the disk 14 so that the holes 26 and 28 will remain opposite the said filling pipes 15.

described will be repeated.

The hole 26 may be continued outward by a. pipe 27 the outer end of which shaped. duced and fed into the apparatus by means of well known or suitable devices forming no parts of the present invention, is during the movement of the lever 28 to the right led through the said pipe 27 and the hole 26 into the filling pipe being for the moment opposite the said hole and thus into the shell on the said filling pipe. The speed at which the string of tobacco is fed through the pipe 27 should be such thatthe shell will be fully will in the same manner as now described be fed into the same and bacco is barred and the said string will thus be somewhat compressed longitudinally if the same is fed continually. Since, however, the backward movement of the lever 23 is very quick in relation to the forward movement such compression causes no disadvantage.

To the lever 23 and opposite the hole 28 is further secured a short is attached a flexible pipe 30 of India rubber or any other suitable material. Through the said flexible pipe .30 is led a current of gas, for instance air, under pressure in the same moment as the said pipe and hole 28, 1

29 in the backward movement of the lever arrives opposite a filling pipe, whereby the cigarette on the latter will be blown olf from the filling pipe and thrown into one of the grooves of the drum 12, the cigarette being retained in the same by means of a projection 33 on the arm 18 and the said protecting screen 22. The above mentioned current of gas'under pressure may be obtained by any well known or suitable device.

Instead of utilizing gas under pressure for removing the cigarette from the filling pipes obviously any mechanical means may be used for the said purpose, for instance one or more reciprocating pins, or the like.

After the cigarettes have been removed from the filling pipes they may pass any well known device for cutting their ends The apparatus described works as follows: The holder is filled with shells whereupon the drum l2 and the lever 23 are put in motion. According as the grooves of the rotary drum 12 pass the holder 17 each of them will receive one shell and the latter will thereupon be placed on the filling pipes by means of the inclined edge of the plate 19. As soon as the first shell arrives at the place where the lever 23 is oscillating, the mechanisms forming the string of tobacco and effecting the current of compressed gas are put in operation. The shells will now while passing the hole and pipe 26, 27 be filled with tobacco and thereupon while passing the hole and tube 28, 29 be removed from the filling pipes and thrown back into the grooves of the drmn 12 where they Will be retained by the protecting screen 22 until they at the lower edge of the latter drop down onto an endless belt 31 or the like, transporting them to any desired place.
