The present invention relates to an apparatus for filling tobacco pipes in which levers and feed screws are used for filling the pipe. Till now, other appliances of this kind have failed, because, on account of the unsuitable arrangement of their levers and spirals, preventing filling the pipes as firmly as absolutely necessary, they were unable to work properly.

According to the present invention, these drawbacks are entirely done away with in a simple manner by the arrangement, inside the tobacco reservoir, of a cylindrically wound feed screw into which, along its whole length, tobacco is fed by means of a spring-pressed partition-plate arranged laterally and serving as a tobacco press. By turning a handle provided outside the tobacco reservoir and standing in connection with the said spiral feed screw, the latter is rotated. This feed screw having a roughened surface, catches the tobacco and draws it into its cavity. From there, when the spiral feed screw turns, the tobacco is pressed towards the opening in the reservoir to which adj oins the opening .of the pipe-bowl. Thus the tobacco is forced firmly into pipe as required by smokers.

The accompanying drawings show, as an example, one form in which the apparatus can be carried out, i. e. Fig. 1 is a plan of the pipe filling apparatus, Fig. 2 shows the aplparatus seen from above, Fig. 3 is the parti-v tion plate for conducting the tobacco within the reservoir, and Fig. 4 is the same plate seen from above.

The tobacco reservoir 1 is provided with a lid 10, 10 consisting of two parts. Part 1Q is firmly attached, while part 10 of the lid 1s loosely joined to the firm part 10 by means of a hinge 12.

Inside the reservoir 1 the feed screw 2 is arranged carried by a tube 3 and, below, supported in a guide-box 17. A stop-ring 4: fixed at the tobacco reservoir 1 prevents the feed screw member with tube 3 from moving up and down. At its upper end tube 3 is provided with a suitable handle by means of which it can be turned with the feed screw member. The handle consists of two parts 5 and 7 connected with each other by a hinge 6.,.Spthat a am be folded up.LV Parma-fries v a pin 8 over which tube-i9 issli'd serving as 9 engages into the handlef `VVhex'ifolding the handle, handle cavity of tube 3.

The manipulati on of the new pipe filling apparatus is as follows:

When reservoir 1 is filled with tobacco and the projecting end 18 of boX 17 is placed on the pipe-bowl, handle 9 is turned to the right, in consequence of which the member 2, which is somewhat roughened on its surface, grips into the tobacco and draws it into the cavity of the spiral member, whereupon the latter presses the tobacco firmly into the pipe-bowl. Plate 16 always keeps on pressing the tobacco, so that the member 2 can always grip tobacco along its whole length. When the pipebowl is filled up turned to the left.

Claims 1. A device of the class described comprising a container, a cylindrically wound feed screw in the container, the sides thereof being parallel to the longitudinal axis thereof,

a spring-pressedplate in the container for forcing tobacco around the feed screw, said plate having its face disposed .parallel withV respect to the lon screw.

gitudinal axis of the feedv 2. A device as claimed in claim 1, wherein the outer faces of the spirals forming the feed screw are roughened.

3. A device of the class described comprisin a container, a tube extending into the contalner, a cylindrically Wound feed screw hav-k ing its upper end connected Withthe'tube, a guide box fixed to the bottom of the container and in which' the lower end of the feed screw engages, a plate movable transversely Within the container, springs in thecontainer for forcing the plate toward the feed screw, said plate being disposed in parallel relation with respect to the`V longitudinal axis of the tube and feed screw.
