The general object of my present invention is to provide an improved combination of a sn'ioking utensil, such as .a pipe, or cigarette or cigar holder with simple and eliectivc means, for eliminating or rendering innocuous injurious and objectionable constituents of the smoke from tobacco or tobacco-like materials, as the smoke passes to I obtain an effective filter action. Without creating an objectionable resistance to the flow of the smoke, and whereby more time than usual is given for chemical action of the filter on the smoke, and whereby I prolong the useful life of each filter which terminates when the filter becomesso fouled by retained impurities as to impair its filtering properties, or to unduly obstruct the flow of smoke through it. The filter is especiallycharacterized by its flat pad-like form, whereby its construction is rendered easy and its assembly in the holder simple. ,Vith this form of filter, the smoke flow. path in the holder is relatively large, and filter renewal may be quickly and easily effected, when fouling of the filter makes renewal deeirable.

In the combustion of tobacco, the gaseous and vapor constituents such as nicotine and others which are most deleterious to the smoker, are alkaline and basic in chemical character, and preferably, though not necessarily, I incorporate in the filter, a suitable chemical for eliminating such deleterious substances or for rendering the latter innocuous. The material used musthave acid properties and must be practically suitable, in that it should be cheap and easy to procure and one which does not itself 'give'a harmful or objectionable odor or taste to the smoke. Filter materials having acidfproperties which I have tried with satisfactory results, include such acids as boric, salicylic and benzoic acids, and the filter material rial no. 60,477)

which I now prefer is powdered boric acid. I have found that boric acid used in the manner described in addition to eliminating objectionable smoke constituents, is advantageous because of its beneficial action on the throat of the user. the manner described not only does not irrita c the throat ofthe user, butexerts aheal ing effect when the throat has been irritated or inflamed from some other cause.

In the preferred mode of construction of my improved filter I may incorporate the chemical material with acid properties in a porous filter body of fabric or paper, by coating or impregnatingthe body With a solution containingsaichmaterial and then drying the filter in which case the acid crystalsformed when the filter dries arcinterspersed through the latterl When the Boric acid used in a filter is formed in the manner described, I

advantageously line or cover it at one or both sides by a protective layer of thin porous cloth. At present, I prefer in practicelthat the chemical material with acid properties employed in the filter be in the form of a powder or mass of fine granules, and be held between-layers of fabric. The fabric which I prefer to employ is a rather thick and loosely woven web of Wool, wool beingsomee what preferable to silk and much superior tocotton for the purpose although cotton, silkor linen can be used. y a y 7 The various features ofpnovelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a partof this specification. For a better understanding of the invention,

however its advantages] and specific [objects attained with its use, reference should 'be had to the accompanying drawings and descriptive matter. in whichI have illustrated and described preferred embodiments of the invention. I

Of the drawings Fig. l is a longitudinal section through a cigarette holder: and

,Fip'. 2 1s a transverse sect on onfthe line e-eoi' Fig. 1. a

In the preferred form of my invention as shown in the -drawings, A represents a p cigarette holder of tubulardorm terminatin? at one end in a mouth-piece A and having an internally threaded socket secured to its opposite end; to. receive a cigarette. lfhe barrel or body i if the holderis half cut away at its upper side for the major portion of its length, the opening being closed by a part E semi-cylindrical in cross section. The part E is secured to-the body part A at the end remote from the mouth piece A by the end piece B which is provided with an internally threaded socket B receiving end portions of the body part A and the end member E which unite to form an externally threaded cylinder. 'At its other end the part E extends under a cylindrical flangeA carried by the member A", and which advantageously is in the form of a metal band surrounding the holder. A filter C inthe form of a fiat pad-like structure is clamped atits edges between portions of the parts A and E. To minimize the possibility of leaky joints, the longitudinal edges of the part E are provided with oppositely inclined surfaces E which unlte With corresponding side edge surfaces A of the member A to provide diametrically opposed V-shaped channels opening into the bore of the cigarette holder and in which the edges of the filter G are received. To assist in bringing the side edges of the parts E and A into proper register and in sealing the joints. against air. leakage, the part A is advantageously provided with longitudinal rib portions A! at the outer edges of the surfaces A which enter rabbets formed for the purpose inthe member E at the outer edges of the surfaces E The filter O 's advantageously formed by two rectangular strips of woolen cloth or other-suitable porous fabricwith a layer D of powdered boric acid or the like, between the fabric layers. There may be more than two layers of cloth and more than one layer of the chemical, but ordinarily I consider a single layer of chemical between two layers of cloth sufiicient. The filter C divides the chamber space in the cigarette holder into two compartments a and a? A mouth piece channel A inclined to the end. of the mouth piece A opens into the compartment a, while the smoke drawn through a cigarette heldin the end piece 13 enters the compartment a through a suitable port E formed in the endportion of the member E.

It willbe understood, of course, that the cloth portions of the filter C are of themselves effective to arrest dust and condensible tar oil and like vapors in the smoke, and also to arrestsome of the nicotine and other positively deleterious constituents of the smoke. Along With a suitable material having acid properties, I may incorporate in the filter other materials to perfume or flavor the smoke. e

In the assemblyfof the smoking utensil shown, the filter padC is placed in position in the barrelA and tile part E inserted under the flange A withthe surfaces E uniting with the surfaces A of the member A to hold the edge portions of the filter C in semi-cylindrical member.

Certain novel and patentable features dis closed but not claimed herein are claimed in my prior application Serial No. 60,477,

filed October 5, 1925, of which this applica tion is a division.

lVhile in accordance with the provisions of the statutes I have illustrated and described the best forms of my invent-ion now known to me, it will be apparent to those skilled in the art that the general principles of my invention may be embodied in other forms of construction, and I do not wish the claimshereinafter made. to be limited to particular details of construction and arrangement disclosed herein more than is made necessary by the terms of the claims and by the prior state of the art.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. A smoking utensil comprising a tubular barrel, a flat pad-like filter extending axially of said barrel and dividing the interior of said barrel into two compartments. 1 2. A smoking utensil comprising a barrel having a chamber therein, a flat Jud-like filter extending axially of and dividlngsaid chamber into two compartments, an inlet passage at one end of one compartment and an outlet passage at the opposite end ofthe other compartment.

3. A smoking utensil comprising a tubular barrel member having a mouth piece at one end thereof and a cut away portion. at one side thereof, a semi-cylindrical member secured to. said barrel member along its cut away. portion, and a filter pad extending axially of said barrel member and secured in position between said barrel member and 4. A smoking utensil comprisinga barrel portion consisting of two semi-cylindrical parts, and a filter having its side edge portions gripped between said semi-cylimlrical parts. i a i 5.
