TOBACCO PIPE.

Application filed May 25, 1928, Serial No. 280,474., and in Great Britain June 25, 1327.

This invention, which may be regarded as a development of that described in specification 271,273, relates to tobacco pipes of the type in which there is interposed in the smoke passage a battle devised to clean, cool and lighten the smoke by causing the deposit of nicotine.

Broadly the invention consists in the provision of a two-part battle comprising an outer element fitted into the mouthpiece and an inner element adjustable in the outer element, the outer element having lateral ports and the inner element having at one end a head devised to break up the smoke and at its opposite end termed as a valve.

In practice, the outer element is screwthreaded externally and internally. The external screw-threads engage ten'iale threads in the mouth piece. Preferably a radial flange, constituting a stop is formed on the outer element to limit the distance which the outer element screws into the mouth piece, so that the portion of the outer element from the flange to the distal extremity of said out-er element which is not screw-threaded externally projects from the mouth-piece and is housed within the pipe-stem when the mouth-piece is fitted to the latter in the usual spigot-joint manner. The lateral ports are :l'ormed in this projecting portion of the outer element. The inner element consists ot' a screw pin or red having a conical. head at its distal end, that is the end turthest from the mouth, and a tapered point at the proximal end. This inner element screws into the projecting end of the outer element, When the inner element is screwed home, the conical head projects from the extremity of the said. projecting end of the outer (lc-llltllt while the tapered end of the inner element finds a seating on the end of the unscrewed portion of the bore of the outer element so that the passage through the outer element is closed, the said tapered end acting as a valve.

hen the pipe is in use, the inner element is not screwed home, but is screwed into the outer element to such a distance that the valve is open to the desired extent, and the draught through the mouth piece controlled as required.

In order that my said invention may be properly understood I have hereunto appended one sheet of explanatory drawings in which Fig. 1 is a vertical section of a pipe fitted with a batlie in accordance with the invention. Fig. 2 comprises an elevation, a plan view and a transverse section of the outer element. F1 3 an elevation of the inner element and Fig. 4: is a plan to a larger scale of the assembled inner and outer elements.

Referring to the drawings The two-part battle referred to consists of an outer element 1 and an inner element 2. The outer element 1 is formed with external screw threads 2, 8 adapted to screw into the mouth piece 4, with lateral ports 5, with a flange 6 constituting a stop, and with in ternal screw threads 7.

The inner element consists of a screw pin or red 2 having a conical head 8 and a tapered end 9. The inner element 2 is screwed into the end of the outer element F 1 with the vertex of the conical. head towards the pipe bowl. When the inner elcment 2 is screwed home, the tapered end 9 finds a seating on the bore 01" the outer element 1.

ll lien the pipe is in use, the inner element is not screwed home, so that the smoke can pass through the ports 5 into the bore of the outer element. The smoker draws smoke through the pipe stem, through the ports 5, through the open valve-controlled port, through thebore of the outer OlQI'IlBIlhZLIld through the mouth piece. The conical head h breaks up the smoke, thereby assisting in the deposit of the nicotine; the broken i-imolre is drawn through the ports 5 and the valve-contrailled port, the e1tcnt of opening oi the latter being adjusted to control the draught.

Having now particularly described and ashaving at one end a head devised to break up the smoke and at its opposite end formed as a valve.

2. A tobacco pipe in the smoke passage of which is interposed an inner bafi'ie element consisting of a screwed pin having a conical head and a tapered end and located in the bore of the pipe stem with the vertex of the cone towards the pipe-bowl, and an outer 2 I I I 1,707,033

tubular baide element into which said inner element is screwed, said outer clement bein; formed with lateral ports, with a radial flange constituting a stop, and with external screw threads,

In testimony whereof I have herennto set my hand.
