' Claims. (01. 131-182) holder which can be simply constructed in a cylindrical form without the necessity of any for thesupport or operation of the ejector.

A further object of thisin'vention is to provide an ejector which is simple in construction, entirely concealed in its assembly in the holder, and which does not interfere either with the inner'surface of the cigarette holding member or with the outer surface of the holder. I

A further object of this invention is to provide a cigarette holder and ejector assembly which is simple and effective in operation, and which does not interfere with the draught through the cigarette, or permit leakage of air around the cigarette into the holder. I I

A further object of this invention is to provide a cigarette holder and ejector assemblyin which the holder and mouthpiece are held firmly to-' gether when the holder is being 'usedtosmoke a cigarette, and are made separable from each other when the ejector is operated to eject a cigarette butt.

A further object of this invention is to provide a cigarette holder and ejector assembly having provision for readily replaceable smoke filters.

Other and further objects will be apparent fromthe following description and the claims.

Figure 10 is a side elevation, partially in section, of the mouthpiece or bit'member, and Figure 11 is an end elevation of this member. e

Describing the drawing in greater detail, the complete cigarette holder comprises aholder member A and a bit member B. The front end of the member A is adapted to receive the end of aycigarette. A tip element l is preferably provided for this purpose. This tip element comprises a cylinder'which isfitted tightly into the front end of the holder A. Itmay also be'provided with a projecting band, preferably'of the same outside diameter as the front end of the holder A, for purpose of ornamentation. The holder A also contains an ejector 4 which is a hollow cylinder fitting loosely' within the bore of the memberA. The front end of the ejector is preferably supplied with a, flat surface, having an outside diameter slightly less than'the inside diameter of the tip member I, for contacting with the butt end of the cigarette during its ejection, and with a smoke passage 5. The ejector is also provided with one or more helical slotsli and with one or more projections pin is used, the ejector is provided with two helicalslots on opposite sides, and the pin passes throughthese slots. Then'the rotation'of the ejector causes it to move longitudinally inthe bore of the holder A by the cooperation of the helical slots 6 with the pin 2. l

diameter of said ring being substantially the same as theoutside diameter of the tip I. For convenience in assembly the ring [5 may be slit so that it can be readily fittedover the ejector.

and may also be made in two separate pieces, either or both having a projection l6. Also, instead of using such a ring, the projections I6 may be mounted directly on, and indeed constructed as a part of, the inner wall of the holder A. In this case, for purpose of assembly, the slots 6 should continue to one end of the ejector 4. When using such projections l6 either on the ring or the wall of the holder, the helical slots 6 may be constructed as grooves in the wall of the ejector and need not be cut entirely through this wall. This structure has the advantage that it lessens the possibility for smoke to pass outside the ejector and for tarry matter to accumulate between the ejector and the holderwall.

The ejector is rotated by means of a tubular elebit B. This tubular element l projects through the rear end of the holder A into the rear end of the ejector 4. Its front end is provided with slots H which engage the projections l of the ejector.

Means are preferably also supplied for holding-the bit and holder members firmly together when the holder is in use. Such means, for example, comprise a projection 12 on the tubular element It for engagement with slots 9 and l9 ina lock member 8 which it fitted tightlyinto the rear end of the boreof the holderA. This lock member can be omitted and the same action obtained by providing a shoulder l1 and groove l8 formed in the inner wall of the holdor A.

There is preferably also provided suitable means for treating and filtering thesmoke. Such means are preferably provided in..a readily removable form such as a cylinder containing suitable smoke filtering materials. A particularly desirable filter for use in this invention isthe gauze roll described in my copendingapplication Serial No. 189,159, filed February '7, 1938.

This is illustrated in FigureQ. The filter .element is held in the tube Ifl by a slightly reduced portion thereof having an inside diameter approximately the same as the outside diameter of the filter. This provides a friction fit between tube and filter sufficiently tight tohoid the filter in place and to prevent air from by-passing the filter in passing through the holder, and sufficiently loose to permit the filter to be readily removed. At the rear of the section 20.is provided means 2| for stopping the filter and for spacing it from the end of the smoke passage. Means 2! may be a projection int .the reduced section 26, and is preferably a further reduction in the diameterthereof, thereby providing a sharp edged, flat shoulder, in a plane perpendicular to the axis of. the tube l0. The thickness of this shoulder, or in other words, the difference in radius of the section 2.0 .and the section 21, is preferably less than thethickness of the coating layers of thegauze .roll'of the filter, and is suitably about one-half this thickness. Sections 2t and2l may each have a length about equal to the diameter of the filter.

The position of the lock member 8 relative to the ejector. is preferably such that the projection I2 is in the longitudinal portion of the slot 9 when the ejector-is in the advanced position for ejecting a cigarette. The parts A and B may then be disconnected simply by pulling them' apart. The shoulder I! or the slot 19 is preferably of helical form so that when the holder is assembled and the bit member is roposefully left larger for clarity in illustration. Itils to be understood, however, that the space between all moving parts should be as narrow as possible in order to prevent flow of air, and

still permitmovement of the parts as indicated herein.

This invention is not to be limited to any specific examples, all of which are presented herein solely for purpose of illustration, as modifications thereof within the scope of the appended claims will. occur to a person skilled in the art. a
