IMPROVEMENT IN SMOKING-TUBES.

Specification forming part of Letters Patent No. 185,284, dated December l2, 1876; application tiled t July 15, 1ste.

To all whom t may concern:

Be it known that I, MARTIN BOURKE, of Mineral Ridge, in the county of Trumbull and State of Ohio, have invented a new and ImA proved Tobacco-Pipe 5 and I do hereby declare the following to be a full, clear, and exact description ot' the same.

In the drawing accompanying and forming part of this specification, Figure l represents a side view of my invention. Fig. 2 is a longitudinal section of the same in the line 00 w of Fig. l. Fig. 3 is a cross-section on line y g/ of' Fig. l.

This device is an improvement-in the class of cigar-pipes, or pipes having the form and general appearance of a cigar, and designed for smoking line-cut tobacco. y

The improvement relatesparticularly to the provision ot' a detachable inner` tube or cylinder for holding the tobacco, and to the form oithe in'ner end of the mouthpiece, against which the tube abuts; also, to a spring attached to a detachable end piece or plug, and whose 'function is to hold the tobacco-tube against the mouth-piece, all as hereinafter more fully described.

In the accompanying drawing, the body 0f the cigar-pipe is shown composed of a tube or cylinder, A, havinga mouth-piece, B, and perforated plug O' attached to its respective ends by means ot bayonet-fastenings, so that they may be readily detached, as occasion requires. The tube D is made ot such size as adapts it to t the interior ot' tube A, and is made about halt' the length ot' the latter. It is uted or grcoved exteriorly to lessen the area of the surface of contact between it and the inclosing-tube A, so that it will not readily A spiral spring, E, is attached to the inner end of plug O, which acts against the contiguous end of the tobacco-tube D, and thus causes the opposite end of the same to press tightly against the inner end of the mouth-piece B. This is necessary to prevent air forcing its way to the latter between the tubes A and D, in place of passing entirely through the tobacco-tube, as required, to support combustion. The inner end ofthe mouth-piece is bored out to form a concavity, a, so that the draft or suction may not be restricted to the center of the body of the tobacco contained in the tube D, but applied to or over the entire end of the saine.

When it is desired to prepare the pipe for smoking, the mouth-piece B is first detached and the tube D removed, filled, lighted, and replaced, and the mouthpiece again attached. It is, however, practicable to till and light the pipe by detaching plug C.

I do not restrict myself to the materials of which the several parts of my improved pipe may be composed, but I prefer to make the tobacco-tube of clay or mcersehaum-chips, in

order that it may have the requisite lightness and lire-resisting quality.

The tubes'A and D may be conveniently and quickly cleaned with a swab, andthe pipe thus kept in proper condition.

As shown in the drawing, the tube or cylinder A is inserted in a wooden tube or case, having a swell at the middle to give it the form and appearance of a cigar.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a tobacco-pipe, the combination, with the cylinder A, of the detachable tube D, the mouth-piece B, spring E, and plug O, having concavity a., substantially as shown and described, t'orthe purpose specified.

2. In a tobacco-pipe, the detachable tube D, tluted or grooved exteriorly, in combination with the cylinder A, as shown and described.
