PIPE BOWL Filed Oct. 23, 1931 Patented Nov. 55, 1932 erase i we e ewe 1 Fed t R a f fl. Li m. i ii f. li vriit HENRI GAUVIN, QF OTTAWA, GNTABIO, CANADA PIPE BOWL Application filed October 23, 1931. Serial No. 570,582.
thorities, however, have shown that this substance is really tar oil which, of course, is very offensive and injurious to some extent.
Virtually, when smoking, the smoker is in eiiect operating a small distillery plant and, through the condensation set up in the pipe bowl, tar oil is formed, all from the combi nation of tobacco, water, heat, combustion, smoke, condensation, saliva, soot, etc.
It is, therefore, 'an object of the present invention entirely to avoid this primary disadvantage by providing a pipe bowl which will entirely eliminate condensation within the pipe and thereby avoid the formation of tar oil, which is a usual result in smoking the ordinary pipe.
A further object of the invention is to provide a very simple form of pipe bowl which may be adapted to any form of pipe and which may be readily manufactured very economically.
A further object of the invention is to provide a pipe bowl which may be made from metal, refractory material or the like, and which will not overheat.
With these and other objects in View, the invention consists essentially in a pipe bowl preferably of the removable type which is of double walled structure, the outside surface of the inner wall constituting the pipe bowl proper and the outer surface of the exterior wall constituting that part of the bowl which contacts with the parts of the pipe in which it is mounted.
A salient feature of the bowl consists in the fact that the walls referred to are spaced apart to form an air-tight chamber within the bowl and entirely surrounding the bowl proper, said chamber being sealed to form a dead air space or a vacuum or filled with an insulating material which will accomplish similar results to a dead air space or vacuum.
This construction will prevent to a large ex tent the transmission of heat from the smoking chamber to other parts of the pipe; and, will eliminate condensation walls of the bowl.
The bowl is provided with to the bottom thereof to permit the passage of air during smoking in the usual manner on the inner M and the bowl may be formed from suitable material, such as a light metal, refractorywj material, or the like, as more fully described in the following specification and illustrated in the accompanying drawing which forms part of the same.
In the drawing Figure 1 illustrates a perspective view of one form of removable bowl.
Figure 2 is a side elevation of the pipe, the bowl structure of which is shown in cross section illustrating, also in cross section, the removable bowl with spaced walls and chamber therebetween.
Figure 3 is a'section taken on the line 33 of Figure 2, and,
Figure 4 is a sectional elevation of a further form in whichthe removable bowl may be constructed.
Referring more particularly to the drawing, .A indicates the improved pipe bowl made according to the present invention and B, for the purposes of illustration, indicates any suitable pipe. The pipe bowl is constructed of the exterior wall 10 and interior wall 11, the interior wall constituting the bowl proper. These walls are spaced apart from each other to form the chamber 12 there between, this chamber entirely surrounding the bowl proper 11 and adapted to house an insulating medium. The base of the pipe 7 bowl is provided with an air passagewaylS which communicates with the interior of the bowl proper and is sealed from the chamber 12 by means of the walls 14.
his"
According to the invention, the chamber 12 I constitutes a dead air space, this being possible due to the fact that'the walls 10, 11 and 14 are entirely sealed and a true dead air space may, therefore, be formed in the chamber 12. Alternatively and preferably, the air is Withdrawn from the chamber 12 to form a vacuum chamber but, on the other hand, it is within the scope of the present invention to pack the chamber 12 with insulating material which will yield practicalvly the same results that are obtained through the dead air space or vacuum.
By constructing the bowl in this manner, the transmission of heat from the bowl proper or smoking chamber 11 to other parts of m the pipe is avoided and also condensaed, apart from the fact that the structure is fire-proof and also odur-proof in view of;
the fact that the formation of tar oil is avoided, which is the main cause of odour.
The bowl A may be applied to a pipe structure in any suitable manner and in Figure 2 one practical form is illustrated. The bowl shell of the pipe is formed in two separable parts 15 and 16, each being screw threaded as at 17 to unite illustrated in Figure 2. T he inturned flanges 18 of the bowl shell will abut the upper edge of the removable pipe bowl A. to lirmly hold it in position when section 15 is screwed tightly upon section 16 and the lower part of the bowl will contact with a suitable washer l9 placed in the section 16 in order to provide a certain resiliency in the seating of the bowl A. The section 17 may be bored to form the well 20 which communicates with the smoking passageway 21 ot' the pipe stem. In this way saliva will remain in the well 20 and will not contact with the to bacco in the bowl proper or smoking chamber 8Q 11 and, since the transmission of heat is large- 7 ly avoided and condensation eliminated, the
formation of tar oil is entirely obviated.
The bowl A, according to the present invention, may be formed in various ways and the formation of the bowl entirely depends on the type of pipe with which it is desired to be used. In Figure 4 one other form of bowl is illustrated which is of practically straight walled structure throughout provided with the insulating chamber and form-ed on the base with a seat 22. This seat may readily extend within a washer or the like, such as 19 illustrated in Figure 2, and provide a very snug-fitting bowl. 59 It is conceivable that in forming an allmetal pipe the integral bowl might be constructed with a chamber such as illustrated in the removable bowl illustrated in the present application and it should be understood that the present invention is applicable to a bowl of this type also but the removable bowl is preferred.
Various modifications may be made in the invention without departing from the spirit thereof or the scope of the claims and, therefore, the exact forms shown are to be taken as illustrative only and not in a limiting sense, and I desire that only such limitationsshall be placed thereon as are imposed by the prior tion on the inner walls of the bowl is avoidart or are specifically set forth in the appended claims.
I claim 1. A removable insert for a pipe bowl comprising a bowl shaped shell formed with double walls in spaced relation, the air from within the space between said walls being exhausted and said space being sealed to provide a vacuum insulation for said bowl.
2. In a pipe, a bowl, a removable insert seated within said bowl and spaced from the walls thereof, said insert comprising a double walled metallic shell having the space between the walls thereof sealed to provide a vacuum chamber.
3. A removable pipe bowl comprising, a double walled shell with the walls thereof in spaced relation providing an intermediate sealed vacuum chamber, said walls being shaped to substantially the contour of a con-' ventional pipe bowl, said shell having a tobacco receiving chamber open at one end and provided with a restricted air passage in the base extending through said walls and sealed from said chamber.
l. In a pipe, a bowl, a removable insert seated within said bowl and spaced from the walls thereof, said insert comprising a double walled shell having the space between-the walls thereof sealed to provide an insulating chamber.
In witness whereof I have hereunto set my hand.
HENRI GAUVIN.
