UNITED STATES JAMES W. IVORY, OF PHILADELPHIA, '.PFl\Tl\TSLVJXLTIA..`
Application filed December 4, 1919.
To all 'LU/tom t may concern: l
Be it known that I, JAMES W. IvonY, a subject of the King ot Great Britain, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Tobacco Pipe, of which the following is a specification. I
My invention relates to an improvement in ordinary tobacco pipes whereby tobacco may be smoked dry and comfortable while avoiding clogging of the base of the bowl and stem of the pipe, preventing Agurglng in the pipe and overcoming an excess of nicotine ljuice formingl in the base ot the bowl and stem of the pipe, and steaming otl the to,- bacco and smoke are avoided. rI`hese and other advantages are achieved by means of an inner bowl placement consisting of a vessel or tray, and an eXtra fresh air passage, or eXtra air passages by means of a perforated stem on the bowl, `or through a perforation in the wall of the bowl at the base thereof through or around said placement, whereby said air mingles with the smoke after the latter is created and leaves the burning tobacco, as will be hereinafter more fully set forth.
The invention is satisfactorily illustrated in the accompanying drawings, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to ythe specicpdetails shown and described, as long as they are within the spirit or scope of the claims.
Figure 1 represents a longitudinal vertical section oi' a tobacco pipe embody-ing my invention.
Figure 2 represents aside elevation of a placement member detached from Figure 1.
Figure 3 represents a vertical section of another embodiment of the invention.
Figure 4 represents a transverse section on line 4-4 Figure 3.
Figures 5, 6, and 8 represent longitudinal sections of other embodiments of the invention.
Figure 7 represents a bottom plan of the placement existing in Figure 6 as removed therefrom.
Similar numerals oi reference indicate corresponding parts in the figures.
Referring to the drawings,
1 designates the bowl of a tobacco pipe, and 2 designates the stem proper thereof. 3 designates a placement in the bottom por- Serial No. 342,568.
tion of the Ibowl on which the tobacco is supported, .the same consisting of a vessel or tra-y having in the circumference thereof the channel 4, the vertical aorts 5 leading to said channel and the threatv ed vertical opening 6 in which may be screwed the end ot the. stem 7, whereby said placement may be located in position and removed therefrom .as desired.
In the portion ot' the wall of the bowl opposite to the stem 2 is an enlarged oriiice 8 which receives the adjacent end of the supplemental stem 9 which extends outwardly from* said wall and has its bore 10 in communication with the circumferentialv channel 4 of the placement.
In said placement 3 is the horizontal passage 11 which is in communication with the ports i5 and the bore of the stem 9., it being seen that the placement supports the tobacco `and prevents clogging oi the base of .the bowl while an eXtra volume of fresh air is drawn into the bowl by the supplemental stem' 9 and commi-ngles with the smoke after the latter leaves the burning tobacco in connection with the air being drawn through the open top of the ybowl as usual and pass ing through. the tobacco an eXtra volume of air then being drawn into the stem proper and from thence into the mouth thus providing a ,dry and comfortable smoke.
Various other'iorms of accomplishing the above results are shown in the other figures as follows:
.In Figures 3 and 4 `,the supplemental stem 9 is extended through the base portion ot the bowl under the perforated placement 3, and joins the neck 12 of the bowl. A chamber 13 exists in the base of the. bowl below the interior portion ot the supple mental stem 9, and a channel 14 exists around said portion of the stem 9 the same being in communication with said chamber 13. In the wall of said supplemental stem 9 is the port 15 which forms a communica tion for the bore of the supplemental stein with said chamber 13 so that smoke is drawn in said bore and commingles with the air entering said bore. In the base portion ot the bowl is the additional port 16 which communicates with the atmosphere and the chamber 13 and admits additional air to the latter.
In Figure 5, the supplemental stem 9 is continuous of the stem* 2 and the bores ot said stems are also continuous. The placement has its perforations 17 in communication with the channel 18 around the supplemental stemi 9 whereby Smoke is directed to the chamber 19 in the bottom of the bowl, the smoke then entering the bore 10 in the supplemental stem 9 through the port 21 in the latter.
In Figures 6 and 7 the placement consists of a block with a recess 22 in the underside of its wall forming the flanges 21 which rest on the bottom of the bowl, the sides of said tube being cut away as at 22 whereby the smoke may pass around saidsides and enter the said recess.
An auxiliary stem 23 is provided, the
, same entering the placement serving to hold the latter in position and communicating With the recess 22 whereby air may be admitted into the latter' and commingle with the smo-ke in its passage to the stern proper.
In Figure 8 a portion of the auxiliary stem enters the base of the bowl the por tion within said base being adapted to sup port the placement thereon and has the pas* sage 28 around the same to receive the smoke from the bowl which is directed by the end of said passage as at 29 into the bore of the neck of the bowl. Air is directed through the bore 10 of said auxiliary stem to the bore in said neck and so commingled smoke and air are directed into the stem proper.
It will be seen that in Figures 3, 4, and 5, the placements are supported on the inner end of the supplemental stems 9. In Figures 6 and 7, the placement is tubular and fitted on and so supported by the inner end of the supplemental stem, said placement having therein the recess 22 whereby the placement is in communication with said supplemental stem and the stem proper.
It will be seen also that whilev the placements lare supported on the supplemental stem the tobacco `will be placed on said placements and so prevent the clogging of the bottom of the bowls.
Furthermoreas a volume of fresh air is drawn into the bowl throuffh sup lementul stems and it mingles with tic smo (e drawn from the bowl the smoking will be easy, dry, comfortable and enjoyable, obviating steaming of the smoke an tobacco in the bottom of the Ibowl and clogging in said bottom, and the bore of the stem proper of the pipe and preventing an excess of nicotine entering said stem nroper, and there will be no gurgling of solutions in the base of the bowl and in the stem,
The placement may be readily removed from the bowl by the handle 7, Figure 2, to the same in the opening 6, Figure 1, so as to cleanse the placement or supply a 'fresh placement to the one that has been in use.
In some cases I provide an additional air supply by means of an extra port or aperture 16 as in Figure 3.
In some cases when it is desirable to hohl the placement in position other than by the inner wall oi the bowl, I employ the screw 39 which is passed upwardly through the bottom of the bowl into the placement, the head of the screw being on the underside of said bottom where it is convenient of access, as shown in Figure 1.
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is
1. In a smoking pipe, a bowl, a stem, an auxiliary air supplying means, the latter in communication with said bowl and said stem, and a perforated lacement in the bowl in communication with said bowl and in contact with said auxiliary air supplying means.
2. In a smoking pipe, a bowl, a stem, and an auxiliary air supplying means, the lat ter having on its exterior in the portion within the bowl a chamber which is in coinmunicaton with said bowl and with said stem.
