Patented Jan. 18, 1938 'E'ES 11 Claims.
This invention relates to tobacco-pipes, and
particularly to improvements for readily main- I therein.
An object of this invention is to provide atobacco-pipe which neither transmits nor collects tobacco-tar within the smoking-stem, and eliminates the undesirable necessity of cleaning tobacco-tar from any narrow ducts or from a multiplicity of collecting surfaces; also to provide a pipe having a free draft, in which all tobaccotar is collected and concentrated in a single absorbing member which is quickly removable by a cleanly operation, not requiring the handling of several separate tar-coated parts, nor subject to binding caused by cold viscous tobacco-tar adhering to separate parts and preventing the easy separation of such parts.
Another object of this invention is to provide a tobacco-pipe in which tobacco-tar and saliva are readily absorbed without obstructing the free passage of smoke from the tobacco through the smoking-stem for an extended period, and in which periodic renewal of the absorbent member is accomplished by a clean, simple and expeditious operation, eliminating the necessity of any additional cleaning, either of a soggy mass of tobacco and tar from the tobacco-bowl or of a residue of tar from any smoke-transmission conduits.
These objects, and others, will be better understood by reference to certain well known facts concerning structures previously disclosed, and to utility of any filter member farther down-stream in the path of transmission from the tobacco to the smokers mouth. Also, absorbent or fibrous meshes such as cotton, for example, which do not have a definitely provided group of passages from the tobacco to the down-stream extremity of the mesh, external to the structure of the mesh, are intrinsically poor for maintaining a satisfactory draft through the pipe, and further, such passages as exist between the fibres of the material itself are subject to large variation by the varying degrees of packing. For these reasons, such meshes disposed either under one or more orifices or ducts of non-absorbent material, or in direct contact with the tobacco, are unsatisfactory for the objects desired. An important feature of this invention is the provision of an absorbent member in direct contact with the tobacco, and having a multiplicity of predetermined indirect passages through the absorbent material, external to the structure of the absorbent material.
With reference to other locations for a filter, hitherto disclosed, it is well known that filters of fibrous meshes or other forms placed for example, in the smoke-transmission conduit between the mouth-piece and the tobacco-bowl, do not eliminate the collection of tar at the junction of the smoke-transmission conduit and the tobacco-bowl, and the duct at this junction must nevertheless be separately cleaned, in addition to renewal of the filter. Both the renewal of such filters and the additional cleaning required, usually necessitate the handling of several separate parts not permanently attached to the pipe, and these separate parts must first be detached, frequently with much difiiculty because of the binding action between parts of cold viscous tar which has accumulated.
An important feature of this invention is the simple and effective means for eliminating the necessity of directly handling detached tar-coated parts, and for attaining a bind-proof seal.
Having pointed out certain facts with reference to tobacco-pipes heretofore described, and some features of my invention, these features and others are better understood by reference to the drawing, in which Fig. 1 shows a side-view of an assembly of the tobacco-pipe, with a centralsection of the tobacco-bowl member, and filter member within the base; Fig. 2 shows a plan view of the bottom of the tobacco-pipe, with further details of the pivoted member and means for securely fastening the pivoted member in its normal position; Fig. 3 shows another plan view of the bottom of the tobacco-pipe, with the pivoted member displaced, and the spiral convolutions of the filter member; Fig. 4 shows a perforated strip of absorbent material, and Fig. 5 shows the same strip when rolled up into a group of spiral convolutions, as seen in a side View; Fig. 6 shows a gasket member for sealing the bottom of the hole through the bottom of the tobacco-bowl membar, and for fastening to the perforated strip to space the spiral convolutions; Fig. 7 shows the filter member as a unit, in side view, and Fig. 8 illustrates in diagram form some of the transmission paths through the filter member, and the principle of the filter member.
Referring to Figs. 1, 2, and 3, at is shown a tobacco-bowl member, and at 2 a hole through the bottom of said member. Opening into the side wall of the hole 2 is the smoke-transmission conduit to within the extension of the tobaccobowl member. The smoking-stern l fits into the extension 6 at la, in a manner well understood, and terminates in the mouth-piece 1d, the conduit lb being continuous through I, from the smoke-transmission conduit to to and through the mouth-piece 701.. At 8 is shown the side-walls of the tobacco-bowl, formed by a layer of carbon deposited within the bore 801, of the tobacco-bowl member. her it fits into the bottom of the hole 2, and the upper part of the member 9 is in direct contact with the tobacco 3 within the bore 8a, and forms a bottom for said bore. Pivotally attached at 5 is the pivoted member 4a, having an enlargement l, anda projection 42) which has a small curvature away from the plane of do for the purpose of engaging the indentation lilb. The under-wall of the extension 6 of the tobaccobowl member has a plane surface Hm with an enlargement ii! in the same planesurface, and symmetrically mounted thereon approximately coplanar with the surfaces l0 and Illa is the pivoted member 4a. This member is preferably of metal, but it will be obvious that other materials can be used. At ii and lo are other plane surfaces in the same plane with each other, and so disposed with reference to the pivoted mem: ber Lia that when the pivoted member is in its normal position symmetrically covering the hole 2, the underside of id is approximately in. the same'plane with H and lo, so as to form an adequate surface upon which the tobaccoepipe can be rested with sufiicient stability to prevent upsetting.
Referring further to the drawing, particularly example blotting-paper, of suficiently larger di-' ameter than the hole 2 so that when tightly pressed against the surface ill, over the bottom of thehole 2, by the enlargement 4, the hole will be sealed sufficiently tight to permit a satisfactory draft to be attained through the tobacco 3. The absorbent material is formed into a group of spiral convolutions, with spaces between the walls oi the convolutions, as shown at 901. A preferred form of filtermember is shown in Fig. 7, in which the gasket member 90 is securely fastened to the spiral convolutions by water-proof cement, as illustrated at 9e. In this form, the convolutions are maintained at a fixed spacing at the gasket member, and the gasket member and strip ii form a complete filter-unit for insertion at the bottom of the tobacco-bowl member.
The principle of operation of the filter is illustrated in further detail, in diagram form, in Fig.
,8. One of the holes 9a, is so located in the strip smoke and'suspended liquid'from the tobacco, TO
through the filter, are illustrated by the arrows l3, emerging from the filter and entering the smoke-transmission conduit, as illustrated at 14.
In numerous paths, the fluid must traverse .a
course having many curvatures before emerging, and the freedom of flow permitted'between the Y ,co-pipe.
filter.
The filter member or absorbent mem walls of the filter is suificient to deposit the heavier tar against the walls of the filter and toward the bottom of the filter. The upper part of the filter, as illustrated at 9:1, is in direct contact with the tobacco, and capable of absorbing relatively large quantities of tar before substantially reducing the draft through the tobac- When there are indications of a reduced draft through the filter, the filter is renewed by using the lever-end of the pivoted member 4a, which is readily disengaged from the indentation I02), and displaced to uncover the In ejecting the used filter, the pipe can be held by the smoking-stem I over an ashreceiver, and the used filter readily pushed out through the bottom of the tobacco-bowl member by means of a match-stick. By inserting a new filter, as described, and returning the pivoted member 4a to its normal position, the
tobacco-pipe is again in condition for a smooth,
clean smoking operation. Because of the fiatsurface form of contact between the member-4 and surface It], and intervening gasket member, binding does not occur between these parts from tar. This form of filter has been found to maintain a clean smoking-stem and smoke-transmission conduit even when used to the extent of a substantial reduction of draft, beyond the indi- 7 changes can be made in the construction and. ar-
rangement of parts without departing from the spirit of myinvention, as further set forth in the appended claims, and I do not therefcrelimit myself'to the form or arrangement shown.
