The upper surface of the casing II forms an annular cavity I1 where ashes or other materials may be deposited.

Cutting means are arranged under the opening I and are operated by pressing the cover 9 down. These cutting means may comprise two knives I8 and I9 of which one may be stationary and theother movable. The stationary knife I8 may, `be ua`1xed to the ceiling 'I by rivets 20. The movable knife is connected to the ceiling 'l by a hinge 2I. In the position of rest, the

sharp Y edges

22 and 23 of these knives surround anV opening which is substantially co-axial with the opening I0. When the knife I9 is turned about the hinge 2l, its sharp edge 22 slides closely under the sharp edge 23 of the knife IB.

This movement is enforced by a guide member 24 affixed to the cover 9. The member 24 has a slot 25 running up-down in an oblique direction. A pin or projection 26v forming an vextension of the movable knife I9 passes through the slot 25 and moves horizontally when the member 24 moves vertically whereby movement of this member swings the knife I9 around its hinge 2| and causes cutting operation of the

edges

22 and 23. Y

A sleeve 21 is slidable in the opening I0 and has a lower rim 28 resting on the upper knife I8.V YThe rim 28 forms a stop for the downwardly directed movement of the cover 9. When the cover is released, the 'spring I4 drives the cover andthe member 24 backto the upper position, the slot 25 guiding the projection 26 and the knife I9 back to the original position shown in the drawings.

A projection or nger 29 extends down from the member 24 and contacts the upper surface of a member 3Il. The member 30 is hinged to an eye 3l which has a horizontal bore and may be affixed to the wall 6 by suitable means, for example, by solder. A spring 32 urges the member 30 against the finger 29. The free end of the member 30 is cut out along lines 33 bordering va 'free space positioned under the opening I0. Thereby the free end of the member 3e forms two lateral arms 34. The free ends of the ,arms `34 carry o o-axial eyes or bearings 35. 'A rectangularplate member 36 is provided with littleV pins turnable in thel eyes 35. In the shown position, the plate 36 covers the space between the arms 34 and forms a stop for a cigarette end which may be dropped through the opening I0. The vertical distance between the plate 36 and the cutting edges22, 23 is equal to or slightly larger than the average length of a burning vcigarette tip. The member 36 forms a lever having a short arm 3'I projecting beyond vthe free ends of the member 39.

When the cover 9 is pressed down, the finger -29 pushes the member 30 whereby the latter, to-

gether with the overlying plate 36, is turned down against Ythe pressure of the spring 32 to the position shown in Fig. 1 in dotted lines.

A hook 38 projectsinto the path of the short `arm l3l of the plate36 at a short distance from the lowermost position of this arm. The hook 38 is hinged to a stationary post 39 which may be affixed to the bottom 5. The post 39 is pro-- vided with a stop 40 preventing the hook 38 from turning incounter-clockwise direction from the tion shown in the drawing whereby the arm 31 is caught under the hook 38.

When the member 39 turns up again, the arm 3l and the plate 36 are rotated about the axis of the eyes 35 by the resistance of the hook 38 as far as necessary in order to let the arm pass the tip of this hook. This turning movement of the plate 36 uncovers temporarily the free space between the arms 34. After having passed the :hook 38 in upward direction the plate 36 falls back on the member 36.

. The lower part of the inner space of the housing is divided into compartments 4I and 42 by a. wall 43 crossing this space parallel to the axis of the eyes 35 and positioned substantially vertically below the lowermost position of this axis.

The described device operates as follows:

When a smoker has finished smoking a cigarette, he drops the remaining end, with its burning tip rst, into the opening I9. The discarded end is stopped by the plate 36 on which it is supported in erect position. In this position the plane dividing the burning tip from the remaining part of the cigarette end is at the same level as the

cutting edges

22 and 23.

Then the smoker presses the cover 9 down. Thereby the knife I9 is moved in the manner described before. Immediately after this knife has started moving, the cigarette end is gripped by the

cutting edges

22 and 23. During the continuation of this movement, the burning tip is cut from the upper part of the cigarette end.

During this cutting operation, the member 39 and the plate 36 have turned down to the position shown in Fig. l in dotted lines. The burning tip drops on the plate 3B and may slide or roll along the upper surface of the plate to the left side in Fig. 1. The upper part of the cigarette end is supported in erect position by the knives I8 and I9 as long as the latter stay closed.

Then the cover 9 is released whereupon it returns to its upper position. At the beginning of this returning movement, the plate 33 is turned in the direction of the arrow 44'in the manner 45 described before whereby the burning tip is thrown into the compartment 4I if this tip should not have dropped into this compartment before that time. This turning Vmovement of the plate 36 uncovers an area or passage between the arms 34. Simultaneously, the knives re-open the passage between the

cutting edges

22 and 23. The cut upper part of the cigarette drops through these passages between the cutting edges and between the arms 34 into the compartment 42. Thereafter all movable parts of the device return to their original positions in which they rest until the device is operated again. lIhe severed parts of the cigarette end are separated by the wall-.43. Theburning part will soon nnish burning. 'Ihe other part will not burn whereby vthe discardedcigarette end will not develop appreciable smoke.

In order toempty Vthe compartments @I and '42, the bottom 5 of the housing is detached from the casing II in the manner described before. Then the cover 9 is taken off and the housing is turned upside down whereby the contents of the housingdrop through the opening 3. The wall 6 of the housing 45 may have openings or interruptions, or a body t5 (see Figs. 5 and 6) may be, used instead of the housing 45. The body 46 differs from the housing 45 in that 'two vertical posts or wall parts 4'! replace the Acylindrical wall 6, in' that two

smaller platforms

48 and 49 forming the tops of the posts 4l replace the annular ceiling 'I and in that a somewhat longer wall 50 having free end sides replaces the wall 43. In every other respect, the body 46 is identical to the previously described housing 45, and this body carries the same parts as the housing 45 in the same manner.

The casing I I is connected to the bottom of the body 46 in the manner described before with respect to the identical bottom 5 whereby this casing closes the sides of the body 45 and, together with this body, forms a housing. The lower space of this housing is divided by the wall 5@ into two compartments which are connected only by narrow gaps 5l. These gaps are far from the central zone where burning tips fall as has been described before. The inner space of the casing I I forms an enlargement of the space of the body 46 whereby the deposition of a large quantity of cigarette ends and ashes is possible. Another advantage is that the body 45 can be emptied k without being turned upside down after the casing I I has been detached.

I desire it understo-od that my invention is not conned to the particular embodiments shown and described, the same being merely illustrative, and that my invention may be carried out in other ways without departing from the spirit of my invention as it is obvious that the particular embodiments shown and described are only two of the many that may be employed to attain the objects of my invention.

Having described the nature of my invention, what I claim and desire to protect by Letters Patent is:

1.
