Application February 21, 1948, Serial No. 10,080

This invention relates to new and useful improvements in smoking pipes,

According to the invention, a smoking pipe is provided which comprises a main hollow structure cross-shaped or cruciform in side elevation and channelled horizontally and vertically, with these channels crossing each other intermediate the ends of both, thus forming horizontal and vertical channeled extensions, in such manner that one of the horizontally channelled extensions acts as a stummel or bit-mounting member, the upper vertically channelled extension provides a mount for a detachable bowl,-the other horizontally channelled extension provides a normal mount for a detachable device for serving, while thus mounted, one of a plurality of special purposes, and the other vertically channelled extension provides at the bottom of said main structure a normal mount for another detachable device having a special purpose while thus mounted.

The first named detachable device, which includes a closure for the main structure opposite the bit carrying end thereof, also includes a rod so fixed to said closure that with the latter normally mounted as above, that is, during smoking of the pipe, the rod extends through substantially the entirety of the horizontal channel through said main structure; whereby there will be condensed or otherwise collected or trapped on the rod the tobacco-oil and the tar-like viscous sub-- stances which during pipe smoking gradually accumulate in an ordinary pipe below the bowl. As is well-known by pipe smokers, these accumulations, if left to themselves, sooner or later interfere with easy and free draw on the smoke, badly clog the pipe, result in the delivery of bitter juices to the mouth of thesmoker, and generally make the pipe malodorous. I

As is also well-known in the smoking pipe art, a fairly small port is employed to afford communication between the bottom of the bowl and the ordinary stummel, and this port is apt frequently to become choked by a piece or particle of tobacco. According to the invention, thistrouble is able to be easily and instantaneously overcome, by use of the rod aforesaid, and, very importantly, by driving the tobacco-choke at the bottom of the bowl, not down into the ordinary stummel as heretofore, ,but upward from the said port and so upward into the bowl.

To perform this operation, it is merely necessary temporarily to detach the second-named detachable device from its normal mounting at the bottom of said main structure, for which bottom,

1 Claim. (Cl. 131-184) ,2 i said device is normally a closure, and then, through thebottom opening thereby provided,- to extend the rod vertically upward into the vertical channel. Since said vertical channel is in line with the smoke-passing port in the bottom of'the' bowl, said rod may be inserted not only through the entirety of said vertical channel, but beyond the top thereof and into the bowl through the bottom port of the latter.

Incidental to each such bowl-clearin operation, naturally the smoker will be reminded to wipe the rod clean from its obnoxious accumulations; and incidental to each removal of the rod for the purpose just noted, naturally the smoker will be reminded to use the rod for bowl-clearing.

The second-named device, removable as above to allow use of the rod for bowl-clearing pursuant to the invention, may be cup-like in nature, thereby, when in place on the main structure, serving as a saliva trap, in and of itself, or through the medium of a contained and discardable cartridge or plucked-wad of compressed or matted raw cotton or the like.

A further feature of the invention, as the same is preferably carried out, is to make said main structure of metal, for quick radiation of excessive heat, thereby to'provide a cool as well as a clean and sweet smoke. said structure, due to its cruciform shape, is quite large, and the consequent loss of heat by radia-- tion is notably advantageous. Another feature of the invention is the use 0 a connector means of the bayonet-joint type, for detachably coupling the bowl to said main structure, and at otherplaces, as for detachably coupling the rod-carrying device to the main structure, and fOr detachably coupling a bowl-liner to and within the bowl.

In the connection last noted, anotherv feature of the invention isthe provision of a liner-bowl, of porcelain, pottery or the like, in combination with a bayonet-joint type of means for detachably connecting such a bowl-liner to and within a main bowl of another material, as one of wood. V t

For further comprehension of the invention, and, of the objects andadvantages thereof, refer'-' ence will be had to the followingfdescriptionand accompanying drawing, and to the appended claim in which the various novel features of the invention are more particularly set forth;

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 shows an embodiment of the invention; as now favored, in side elevation.

The radiation areaof Fig. 2 is a longitudinal vertical section through the same; with, however, a, chain elsewhere shown omitted.

Fig. 3 is a view similar to Fig. 1, but showing 2 rearrangement of the parts for bowl-clearing.

Fig. 4 is a transverse vertical section, taken on the line 4-4 of Fig. 3.

Fig. 5 is a fragmentary side elevation, partially broken away and partially in section, showing a coupling means between the bowl and the main structure which is of screw-thread type rather than of bayonet-joint type.

Fig. 6 is a view similar to Fig. 2, showing another now favored embodiment.

Fig. '7 shows in perspective one of the parts the pipe shown in Fig. 6.

Referring to the drawing more in detail, It

designates the aforesaid main structure, cruciform in side elevation, having an upward extension II, a depending extension I2, a forward extension I4 and a rearward extension I5. A horizontal channel. I6 open at both ends passes longitudinally through the structure I0. Intermediate the ends of the channel I6 the same is intersected by a vertical channel, thereby to have the lastmentioned channel provide an upper chamber I1 and a' lower chamber I8. These chambers are centered below the bowl I9.

The main structure In is desirably of metal, and may be in the form of a single casting, suitably machined. V

The forward extension I4 has the function of the stummel of an ordinary pipe, for detachably carrying a bit 20. The bit 20 is shown in Fig. 2 as frictionally gripped at its reduced end 20- in the extension I4, but as will be understood there may be here a screw-threaded or any other suitable connection.

The rod aforesaid is marked 2 I, and the same is rigidly carried by a cap 22 having a cylindrical skirt 22 for detachably sleeving the extension I5. These parts are also desirably of metal. Normally, the rod 2I extends through the channel IB as in Fig. 2, with the cap 22 closing, the extension I5 in an airtight'manner.

The bottom of the extension I2 is normally closed by a removable cup 23 having a cylindrical skirt 23 for entering the lower portion of the chamber I8 within the extension I2 and then abutting a shoulder 24 in said chamber. The cup 23 is also desirably of metal. The cup 23, even when temporarily disconnected from the structure III as in Figs. 3 and 4, is held captive by a flexible element, as a chain 25; said chain attached at one end to an apertured lug 23 projected from the cup 23 and attached at its other end to an apertured ear 26 on the structure ID.

The securement of the cup 23 to the extension I2 for normally closing the bottom of the latter may be by frictional grip, or by way of a screwthread type of connection, or otherwise, as, for instance, by way of a bayonet-type of connection (not shown) butsuch as illustrated and below described in connection with the cup 22, the bowl I9, and a bowl-liner 2I--which'bowl-liner, desirably made of porcelain, pottery or the like, is desirably present. For assistance in manually applying a turning force to the cup 23, in attaching or detaching the same, said cup is illustrated as having a plurality of short outwardly and downwardly inclined fingers 29, spaced around the cup'120 apart.

The cup 23 provided with the skirt 23 may be employed as a saliva trap, and in that connection a cartridge or plucked-wad 28 of compressed 4 or matted raw cotton or the like may be deposited in such cup, for replacement when fouled.

Referring to the illustrated connecting means between the cap 22 and the extension I5, which cap is shown as circumferentially knurled beyond the skirt 22, said connecting means is shown as comprising a pair of oppositely located bayonet joints each including an L-shaped slot 36 through the skirt 22 of the cap 22 and a coacting pin 3| offset from the extension I5; one of such slots and its pin being shown in Fig. l.

A similar connecting means is illustrated as provided for the bowl I9 and the extension II; the bowl having a depending neck for entering the upper end of the chamber I1 and for resting at its bottom on a shoulder 32 in said chamber. This connecting means is shown as comprising a pair of oppositely located bayonet joints each ineluding an L-shaped slot 33 through said neck of the bowl and a pair of coacting pins 34 carried at the upper end of the extension I I and inwardly offset therefrom above the shoulder 32.

Inregard to the bowl-liner 21, which is shown only in connection with the embodiment of Figs. 1-4, but which may also be present in the form of the invention shown in Fig. 5, this is readilyv detachable, as for cleaning, close inspection or replacement; and the same is shown as secured within the bowl I9 also by a bayonet-joint connection, such connection comprising a pair of L-shaped slots 35 through the bowl-liner at its upper end and a pair of coacting pins 36 carried by the bowl I9 and inwardly projected therefrom. The bowl-liner has a central bottom smoke passage port 31.

While the pipe is being smoked, the parts are arranged as in Fig. 2. Then the tobacco-on and viscous matters aforesaid are accumulated on the rod 2 I, and deposits of saliva drop into the lower portion of the chamber I8 in the extension I2 for reception in the cupped portion presented by the skirt 23 of the cup 23. For cleaning the rod, the same is withdrawn from the channel I6 following detachment of the cap 22. For cleaning out the saliva, and for renewing the element 28 when advisable, the cap 22 is detached.

In order to eject from the port 3'! of the bowlliner '2'! a choking or clogging tobacco piece or particle therein, it is merely necessary to employ the rod 2| as shown in Figs. 3 and 4; that is, first to disconnect the cup 23 and allow the same to dangle from the chain 25, and then, using the cap 22 as a. handle, to insert the rod 2I upwardly through the chambers I8 and I! and then through the port 31 and into the bowl-liner 21. As will be noted from Fig. 4, the external diameter of the skirt 22 of the cap 22 matches the internal diameter of the lower part of the chamber I8; whereas, as appears in Fig. 2, the internal diameter of the skirt 22 matches the external diameter of the extension I5.

Referring to the form of the invention shown in Fig. 5, the parts here shown and to which reference characters with primes are applied correspond to the parts of Figs. 1-4 to which reference characters without primes are applied. In the arrangement of Fig. 5, the upper portion of the chamber I'l is internally threaded, and the neck'at the lower end of the bowl I9 is suitably constricted so as properly to carry an external thread matching such internal thread, as shown at 38. The neck of the bowl IS has extended through the same a port or passage 39 also of a diameter to have passed upwardly therethrough the rod 2! as and for the purpose explained in connection with Figs. 1 to 4.

Referring to Figs. 6 and 7, the modification here shown is like that of Figs. 1-4, except that the bowl 40 is of metal and integral with the main structure corresponding to the structure It. The same bit is shown as present, as well as the same cap 22 and cup 23 and the same chain 25. The rod 2! carried by the cap 22 is for use as already described.

The bowl-liner 4!, of porcelain, pottery or the like, has a bottom outwardly flaring skirt portion 42 for assisting to position the bowl-liner in the bowl as illustrated. The bowl-liner ii is held thus positioned by a removable metal ring 43 having three depending resilient tongues 44 snapped into interlock with an external peripheral bead 45 near the top of the bowl 40.

The bowl-liner 4| has a central bottom smokepassing port 66 in alignment with the axis of a vertical channel 48 corresponding to the vertical channel of the main structure l0 and hence intersecting a horizontal channel corresponding to the channel iii.

A filter 47 of a suitable and preferably of a fibrous material, and desirably shaped as shown, that is, of slenderized frusto-conical form, is positioned in the vertical channel 48. The filter M, as here illustrated, is of a height such that its top is at the bottom of the bowl-liner 4 i, with the bottom of the filter near the bottom of said vertical channel and abutting the cup 23. The top Of the filter 47 is in intimate contact with the bowl-liner 4i and is concentric with the port 4%.

As a result of this arrangement, a pipe is provided with an absolutely dry bowl.

Furthermore, the filter 41 is shaped to have a longitudinal bore 49, and a transverse bore 59 through which, with the filter properly angularly adjusted, the rod 2! normally extends. Should the port 45 become tobacco-clogged, the cap 22 may be removed, withdrawing the rod 2| from the filter and the main structure, and then, as in the case of the combination of Figs. 1-3, after detachment of the cup 23, the rod 2! may be passed upward through the main structure (in the present case, by way of the bore 49 through the filter), for passage through the port 45, as indicated in dot and dash lines in Fig. 6, to clear said port.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I 6 claim as new, and desire to secure by United States Letters Patent is:

A smoking pipe comprising a main structure cruciform in side elevation, said structure having a horizontal channel from end to end providing a hollow forward extension and a hollow rearward extension and a vertical channel intersecting said horizontal channel intermediate of its ends providing a hollow upward extension and a hollow depending extension, a bowl extending up wardly from said upward extension, a bit detachably connected to said forward extension, a bowlliner mounted in said bowl and having a bottom port aligned with said vertical channel, a detachable closure for the rear end of said rearward extension, a detachable closure for the bottom of said depending extension, a rod-like member projected from the first-named closure into said horizontal channel, so constructed and arranged that when the pipe is smoked with both closures in place said rod-like member functions for the accumulation of viscous matters and the like and the second-named closure functions for saliva trapping; and when said port of said bowl-liner is tobacco-choked, said rod-like member following removal of said closures, may be inserted upward through said vertical channel and then upward through said port to clear said port, and an elongated removable filter in said vertical chan nel with its length extended vertically for placement of the top of said filter against the bottom of said bowl-liner in concentric alignment with said port with the bottom of said filter in the bottom of said vertical channel, abutting said second closure, said filter being of a nature to allow passage therethrough of said rod either lengthwisely or laterally thereof.
