1 Claim.

This invention concerns certain improvements which I effected in means to be applied to cigaror cigarette-holders for filtering the smoke of the tobacco.

At present filters consist of simple cylindrical cartridges having perforated ends and being filled with fibres, preferably cotton, said cartridges being placed within a cavity made expressly in the body of the holder.

These common filters present the inconvenience that they need a space between the end of the cartridge and that of the holder into which the cigar or cigarette is put, and furthermore that they leave a small annular space through which passes the smoke Without being filtered. At said space at the end of the holder there accumulates dirt which undoubtedly contributes to damage the aroma of the tobacco.

The same happens at the tubular part which at the other end of the cartridge remains between this and the end of the holder.

The improvements which form the subject matter of the present application have the purpose of eliminating said inconveniences, firstly by obliging the end of the cigar or cigarette to penetrate into a tubular extension of the filter cartridge, and'secondly by providing this latter at the opposed end with an extension which has the purpose of filling the conduit through which the smoke passes to the mouth, after having passed through the filtering material.

As will be seen later on, the extensions at one and the other end of the filter cartridge require a cavity specially made in the holder.

For the better comprehension of this specification a detailed drawing is added wherein:

Fig. 1 shows a central longitudinal section of a filter and a holder improved in accordance with this invention;

Fig. 2 is a projection of the assembly of the filter and separate parts of the holder.

In the drawing the numerals I and 2 indicate the sections which compose the body of the holder and these sections are united by a screw thread 3. Into the interior of the sections is inserted a filter which comprises an elongated shell 4 having filter material I located at an intermediate portion thereof. This filtering material is held in place by perforated disks 5 and 6 located adjacent opposite ends of the material.

An extension 40. forms the forward end of the shell 4 and this extension receives one end of a cigarette or cigar and this end is completely housed within the extension. Said shell is tapered adjacent its opposite end where it fits into the tapered mouth-piece section 2.

The opposite ends of the sections l and 2 are provided with passages which alinewith similarly positioned passages in the shell 4. It will be noted that the outer end or" the section I is provided with an inturned flange 8 which forms a shoulder to engage the free edge of the extension 4a of the shell 4. Thus it will be seen that when the shell 4 is fitted into the sections l and 2 and these sections are removably connected together by the threads, 3 the shell 4 will be rigidly mounted within the sections by the flange 8 and the tapered portion of the section 2. Since the shell is neatly fitted within the sections I and 2 of the body and the opposite ends thereof are in direct engagement with the opposite ends of these sections 1 and. 2 all smoke which is drawn through the cigarette or cigar and into the holder must pass only through the hollow shell, whereby no smoke will come in contact with the sections of the body and thus the body can be maintained clean at all times.

Body 4, although preferably consisting of glass in view of the cheapness of the material, its transparency and ease of manufacture, however can be of any other material which is considered convenient. Also the material and the shape of parts I and 2 is variable at will.

As concerns the filtering material, this can consist of cork or coal pellets, silica gel, fibres, either alone or in admixture, or of any other adequate material.

I claim:

A cigar or cigarette holder comprising an elongated hollow body having an opening at each of its opposite ends, the hollow body comprising readily separable sections, a filter within the hollow body consisting of a shell neatly fitting the entire inner wall surface of the hollow body, and a filtering material disposed in an intermediate portion of the shell, said shell having openings at its opposite ends alining with the openings in the hollow body, said hollow body at one end being adapted to receive an end of a cigar or cigarette, the shell terminating at one end adjacent the last-mentioned opening in the body to substantially completely house the inserted end of the cigar or cigarette and having its end edge in engagement with and retained by a shoulder portion of said hollow body, the hollow body being tapered at its opposite end to form a mouth piece, the shell likewise being tapered adjacent the mouth piece and neatly filling said tapered mouth piece.
