SMOKING-PIPE.

Specification of Letters Batent: 1 Patghted A g. 31 1915 Application filed August 6, 1914. Serial No. 855,456.

This invention relates to smoking pipes and to a cleaner therefor, the cleaner being adapted to be removably carried in the pipe and the pipe being arranged so as to be capable of receiving the cleaner for this purpose.

The invention consists of the particular construction of the parts as hereinafter described and claimed and as illustrated in the accompanying drawing in which:

Figure 1, shows in longitudinal section a pipe of conventional type, embodying the features of my invention and with the cleaner in position. Fig. 2, is an enlarged end View of the mouth piece of this pipe. Fig. 3, is a top view and Fig. 4-, is a side view of the mouth piece as it appears in Fig. 1. Fig. 5, shows the cleaner removed. Fig. 6, is an enlarged cross section of the shank of this cleaner. Fig. 7 shows manipulation of the cleaner for the purpose of inserting the same into the pipe. Fig. 8, shows a modified construction of the cleaner.

In the drawing numeral 8 indicates the bowl of the pipe.

9 indicates the shank or stummel thereof and 10 is the mouth-piece.

The cleaner consists of a number of spines 11 of steel wire closely bunched at one end and held together by a tubular socket 12, the latter being compressed after the spines are inserted to hold them firmly in place as indicated in dotted lines in Fig. 6. In the construction shown in Fig. 8 they are bound together between their ends. This socket forms the shank of the cleaner whereby it is heldwhile manipulated for cleaning the pipe. In their normal condition the free ends of the spines have a tendency to spread as shown in Figs. 5 and 8. For in sertion of the cleaner, the free ends of the spines are held together as shown in Fig. 7 to facilitate their entrance into the mouthpiece. One of the spines is extended beyond the outer end of socket 12 and bent away at right angles to form a short catch 13 to facilitate withdrawal of the cleaner from the pipe in the manner indicated in Fig. 3. In.

the normal condition and when the cleaner occupies its position within the pipe, this catch rests in a groove 14 in the end of the mouth-piece; In thisposition this catch is not noticeable and does not become 0bjectionable. i

The cleaner is of a length, that when so inserted, the free ends of the spines extend into the bottom of the bowl of the pipe.

-The bore which forms the draft duct for the passage of smoke through the stummel and through the mouth-piece is of a diameter which prevents interference by the inserted cleaner with the drawing of smoke through the smoke duct when the pipe is used. The elastic tendency of the spines which causes them to spread holds them in close contact with the sides of the smoke passage so that the cleaner readily retains its position. Occupying a position as they do, and where obstruction mostly occurs in the draft duct, namely where it joins the bowl, these spines reduce this possibility and when obstruction occurs their withdrawal causes also removal of the obstruction at once- Furthermore being of metal the spines become hot reduce thereby accumulation of moisture and tend to keep this part of the duct and the lower part of the bowl comparatively dry. Farther up in the duct, these spines act as a trap by intercepting nicotin-carrying moisture which condenses and accumulates on them so that when the cleaner is withdrawn for cleaning, the larger part of accumulated matter passes out with it.

The cleaning effect may be increased by turning and twisting the cleaner during the act of withdrawing it. After withdrawal, it is readily cleaned by wiping or by holding it under running water. The cleaner being flexible accommodates itself to any shape of the mouth-piece or stummel and readily follows this shape if these parts are curved. v v

The cleaner may obviously be used independently and on any other pipe not necessarily the one in which it is carried and with any possible mode of manipulation, as for instance, the mouth-piece havingbeen detached from the stummel, each of them may be cleaned separately. In this mode of manipulation the cleaner, if carried in the pipe, becomes readily accessible after the mouthpiece is detached, so that the use of catch 13 is not necessarily required for In combination with a pipe which com-' prises amouth-piece provided with a groove extending from the duct-opening therein across its end, a cleaner consisting of a plural y of pin f-Qli S rebu h and hel d'together at one endand adapted to co cupy the smoke duct ofsaid' pipe in which the cleaner-is removablyheld by the spreads ingtendency of its spines and by theinconsequential contact with the sides of the smoke duct, one of said spines being longer and extended beyond the mouth-piece and bent to form a catch to facilitate removal of the cleaner, said catch in normal condition occupying the groove in the mouthpiece mentioned. 1 i

In testimony whereof, I hereunto afiix ,my signature in the presence of two wit- 1 Copies of this patent may be obtained for five ce nts eachp'by addressing the Commissioner of Patents,
