TOBACCO PIPE.

Application filed February 6, 1922.

To ZZ whom t may conccfmi:

Be it known that I, F REDERIGK EDWARD VEsEr BEANES, a subject of the King of Great Britain, and resident of Falcon lVorks, lVallis Road, Hackney lVick, London, E. 9, England, have invented certain new and useful Improvements in Tobacco Pipes, for which I have liled an application in England, dated December 22nd, 1921, ot' which the following is a specification.

This invention relates to tobacco pipes, and it has Jfor its object to provide a pipe with an improved bore of bowl and stem, enabling the smoke from the tobacco to be drawn through the pipe with less source of obstruction at the orifice from the bowl into the stem, thus giving a free draught at all times, more complete combustion of the tobacco and dispersal of condensed moisture.

The invention will be described with ret erence to the accompanying drawing where- Figure l shows a pipe in longitudinal vertical section.

Figure 2 shows the same in plan view.

Figure 3 shows the bowl of 'the pipe in transverse vertical section on the line 3 3 of Figure l. 1

Figure 4L is a sectional view corresponding to Figure l, showing a form of pipe as used to a large extent hitherto.

Figure 5 is a similar sectional view to Figure l showing the invention as applied to a pipe of another shape.

Referring first to Figures l to 3, it will be seen that the bowl a of the pipe is first bored out to form a rounded conical or paraboloid bore Z as is usual, and then a recess is formed at the lower end of the bore as at Z) by the use of a milling cutter for example, this recess forming an extension of the bore Z adjacent the place where bore m of the stem c of the pipe communicates with the bore Z. The side face of this recess Z) is approximately parallel with the axis of the pipe bowl a, i. e. approximately at right angles to the axis of the stem c of the pipe in the case of a straight pipe as in Figures l to 3. The stem c of the pipe is bored out so as to provide a comparatively wide bore m extending nearly to the bore Z, but terminating in a conical or taper` ing portion (Z so as to provide an aperture or draught hole at e where the bore m opens Serial No. 534,603.

into the recess b; This draught hole e is small enough to retain the tobacco iu position in the bowl while permitting the smoke to be drawn freely through it into the bore of the stem 0,' and the rapidly enlarging bore at Z back of the hole e insures that no particles which may pass into the hole e will remain therein and cause an obstruction, because any particle small enough to pass through hole c can be drawn through it at once into the wider bore m in the stem, and can remain there without obstructing the draught passa-ge through c. The stem has a mouthpiece fitted to the same in any usual or convenient manner, a mouthpiece being indicated in dotted lines at f in Figures l and 2.

When the tobacco is pressed down in the bowl of the pipe, the pressure at the side near the orice c is relieved by the recess which does not become choked with tightly packed tobacco, because the tapering bore Z of the bowl takes the pressure, and the recess at b is not large enough in relation to the bore of the bowl to permit the tobacco to be pressed into it to any considerable extent. This insures a free draught at the hole e, resulting in better combustion of the tobacco and dispersal of moisture which would otherwise tend to condense at the bottom of the bowl.

VAs the recess b is provided with a vertical side ;tace n, the draught hole c will be -out of the range of a pipe scraper or a knife used for clearing out the bore Z, so that there is no substantial risk of the hole c being enlarged by this operation. The hole e is further protected by the fact that it opens into the recess Z), while a scraping tool litting into the normal bore of the bowl will be prevented by the general shape of the bowl cavity from engaging with the side face n of the recess adjacent the'hole e.

It will be obvious that the tapering of the bore m as at CZ will facilitate the cleaning out of the said bore, in that there is no sharp corner or shoulder la (see Fig. 4) in the bore m against which a cleaning mem ber or wire can catch.

I have found in practice that pipes made in the manner described and illustrated in Figures l to 3 are in fact much more satis factory in use than pipes made in the man ner hitherto usual, as indicated for example in Figure Ll, which shows a pipe having a relatively long and small bore g opening at l1, into, the, bottom of a bowl, which latter is bored out'to a perebolod curvature, The tobacco tends to be packed tightly at the opening It Lof the draught hole, and condensed moisture tends toA pass directly into the draught hole. The shoulder at 7c also. tends to obstruct the easy cleaning out of the bore hole in this Case. On the other hand, in the pipe shown in Figures 1 to 3, I .nd that the tobaooo burns. cleanly and freely down to the bottom of the bore. Z, while the1tendenoyV to obstructionl of. the draught holeAv or to the drawing in oft-moisture .through it is greatly reduced, and the satisfaction obtained from the, smoking of SuchL @Pipe is therefore greatly increased.

Tfherinventioncanbe applied asindica-ted in Figurer 5 to a pipe in which the stemc is .et en, ecute. engleto the. axis. of the bowls, and from what. hasebeen stated above, this figure in which eachpart islettered tocorrespond with corresponding. parts. in Eigures. l toE l 3, will requireY nov further .explanation.

It will be apparent that pipes according to this invention may bepmatle of any suit? able materials, and although they invention has been described asappliedto pipes having'.- the. bowlv and stelen` of wood. orother natural material, tllezpipemay: be moulded in clayor other materials, provided that lthe boreinthe bowl is shapedin` the moulding of the bowl, whilethe bore, or passagein the,v stem ,is` shaped as. above described.

Haring thus described .my invention what I. claim ,asnew and desire ytosecure by Let, ters Patent/.is 1. In @tobacco pipe. a-bowl having a. bore therein, said bore ,contracting-v towards the bottom of the bowl, thesaidboreghaving a recess; abone side ofthe bottom thereof, lthe said recess extendino' downwardly beyond the bottom ozthe bovevwhilst the outer Well thereof is substantially parallel with the axis of the pipe bowl, and a pipe stem formed integralwith the bowl, said pipe stem having n. bore of large diameter therein, the bore in the stem communicating with the said recess above the bottom thereof and adjacent said recess being reduced in area so ytherein said bore contract-ing towards the bottom of the bowl, and apipe stem formed integral with said bowl, said pipe stem. having. a bore of large diameter thev end of which adjacent the bowl terminates in a conical portion so as to form a small draught` hole, the bore of,v the bowl having an eecentrically arranged circular recess with the outer Wall of which thedraigght hole communicates, said recess being extended downwardly in the bowl below the level of the draught hole and below the bottom of thebore in the bowl, one wall of the recess being substantially parallel with the, axis. ofV theA pipe` bowl, they arrangement beingsuc-h that when tobacco, is presaedinto the bore,A ofithebowl the pressure near the draught hole is relieved by the reoes which doesnot become-choked with tobacco.
