R. HIRSCH SMOKER 8 ARTICLE Filed April 1, 1936 Patented Mar. 22, 1938 UNITED STATES PATIENT-"OFFICE Application April 1,

1 Claim. This invention relates tothat class of objects known as smokers articles and in particular to smokers pipes.

Pipes of various types are known which have been lined with, various compositions such as licorice and a solid, syrup and a solid or honey and a solid. It will be noted that these linings all have as a base, a liquid substance which is likely to be dried out over a period of time if the interior of the pipes is subjected to the varying con ditions of the air known to exist in warehouses,v

stores or other places of storage or display. The linings may thus be subject to. chemical or physical changes. 7

3 It is an object of this invention to protect these linings from variations of the atmosphere.

It is another object of this invention to protect thelining fromthe chemical or physical change or injury by providing simple packing and closure means all within the bowl of the pipe.

It is well known also that tobacco has been used as the solid referred to above to form the lining, while the licorice was used to bind the tobacco and sweeten the pipe. This has been found unsatisfactory since the tobacco burns out of the pipe lining and'leaves a gummy mass of licorice upon the walls. of the pipe. The pores.

of the pipe become clogged, and the pipe becomes strong. According to this invention a porous, preferably non-combustible material may be used and mixed with a. honey binder. It is an object. tov provide a pipe with such a porous binder, and it is a further object to cure this lining with tobacco while the pipeis on display. It is yet another object of this invention to. provide economical and easily removed closure means for retaining the tobacco within the pipe.

Another object is to provide a pipe which may beoffered for saleready tobe smoked. And it i is. 'a further object to provide for the smoking public a pipe lined 0r unlined and partially cured with the proper tobacco.

It is not generally known amongsmokers that the first pipeful of tobacco smoked in a new pipe should be a pure tobacco uncontaminated with prune juice, licorice or other gummy substances. Tobacco of the preferred type is not readily obtainable in quantities small enough for the single pipeful needed. It is an object to provide a pipe packed with tobacco of the type correct for breaking in a pipe.

I am aware that filled pipes of various kinds have been made and offered for sale. These pipes have been, so far as I am aware, of a very temporary material. Also the tobacco was re- 1936, Serial No. 72.169 (01. 131-42) tained in the bowl by a suitable lid or cover glued or otherwise held upon the outside of the bowl.

. Thesepipes were unsatisfactory because the glue gummedthe pipe and smelled when it, became hot. Also this and other closure retaining means 5 marred the outer surface of the pipe.

It is an object of this invention to provide a pipe of a permanent type containing tobacco. It is a further object to retain the tobacco within the pipe by closure, means within the pipe such that the beauty of the bowl is not impaired.

These and other objects and advantages will appeanfrom the following description of my invention in, which I refer to the appended drawing throughout the various figures of whichlike numerals refer to like parts and in which:

Fig. l is a perspective View of one style of pipe showing the closure means;

Fig. 2 is a side elevation ofathe pipe bowl partly in section;

Fig. 4 is, atop View partly in: perspective of a second embodiment of the closure member, and

Fig. 5 is. a section through the closure member along line5=5 of Fig. 4. i

As clearly shown in the preferred embodiment of my invention depicted in Figs. 1 and 2, I have provideda well known shape of briar pipe 2 with a lining 4. I prefer to make'this lining of. a plastic mass of pure honey and a porous, noncombustible, solid material which has'been comminuted to. the desired degree of fineness. When this plastic mass has been mixed in such proportionsfastosform a plastic mass which has a very.

slight fiow coeificient it is applied to the inner surface of the pipe in any manner such as by moulding about .a collapsible core. The pipe may be treated in any way to cause the lining to set, such as by baking. The baking process, if this be used, must, however, bestopped before the honey becomes dried out to such an extent as to crumble. The invention contemplates the continuedmaintenance of the'lining in that degree of moisture which is best suited to carry out the purpose of the lining.'

While I have hereto-fore referred to a briar pipe with a lining, it will be manifest that it is Within the spirit of my intention to embody my invention in pipes having varous shapes of bowls and various combinations of materials, whether moulded or milled. It will be obvious that I may use a lining or not because the structure alone, as well as the discovery of the need for and the beneficial result of the structure, is an important part of my invention.

Referring to Figs. 1 and 2, the lining material is finished in a convex curve 6 fora space from the top of the lining. The inner surface of the lining, or the inner surface of the pipe bowl, if no lining be used, is then curved concavely as at 8 to form an annular groove. While it is not essential that this groove be of any particular width, that is, from top toward the bottom of the pipe, it is preferable slightly wider than the thickness of well known three-ply paperboard commonly known as cardboard.

The pipe bowl is next packed with an unsweetened tobacco l possessing a degree of moisture which may be found from experiment to be most suitable for breaking in pipes. A clear Havana type tobacco which is slightly crimp out has been found by me to be most suitable, since this leaves the pipe in a sweet ungummed condition. I have found also that this type of tobacco has beneficial results as a curing tobacco since it permeates the porous material of the lining or the pipe bowl and impregnates these materials with a sweet tobacco taste.

The degree of moisture which I have found most suited for retaining the pipe bowl or lining in condition may be determined by touch rather than by the use of complicated testing apparatus. The tobacco should be such that it will feel slightly dry but will not powder when it is rolled between the hands.

I use a slightly crimp cut tobacco which is packed in the bowl up to the lower limit of the annular groove 8. A closure member 12 is then pressed into the pipe bowl until it springs into place in the groove 8.

Preferably this closure member consists of a 3- ply paper disc having a diameter slightly less than the distance from the bottom surface to the opposite bottom surface of the groove 8. Perfect fit is not essential since the above mentioned crimp cut tobacco has the tendency to expand by uncurling. This expansion of the tobacco urges the disc tightly against the upper side of the groove and insures a seal. It will be obvious, of course, that I may use oval shaped closure members for pipes with oval bowls since the invention is not limited to a particular shape of bowl. Also I may, if I find it desirable, treat the closure member with a moisture-proofing compound before the closure members are diecut from the sheet. Paraffin might, for instance, be spread upon the surfaces of the paper sheet or a coating of shellac applied. Also a cellophane or other moisture-impervious material could well be used in combination with these closure members. It would be economical to apply a sheet of cellophane to the sheet of paper which is to be die-cut to form the closure members. The laminated fabric would then be out out in a single operation.

As shown in a second embodiment of my invention depicted inFigs. 4 and 5, I may provide the disc l2 with an integral tab for ease of removal. The tab I4 may be formed by making a U-shaped line of cut I6 part way through the body of the disc.

It will be obvious that I have discovered a simple form of closure member which is preferably for use in retaining a quantity of tobacco in unused pipes. It will be equally manifest that the closure member is not limited to use with new pipes. For instance. I may supply a quantity of suitable discs to be later used to retain the ashes and unused portion of the tobacco from spilling into a smokers pocket or on a desk or table. I am aware that others have disclosed various means for the accomplishment of this same end. However, no other person has provided a closure member of such convenience and simplicity. Nor has anyone produced a closure member which may be so economically producedthat it may be thrown away after one use and at a slight cost. Metallic devices which are retained by spring arms have been used but these have many disadvantages, such, for instance, as the necessity of folding and unfolding the arms. Others have disclosed a sack-like device of rubber and asbestos which may be rolled upon the pipe. Yet other pipes have been provided with a flat base so that they may be kept in an upright position.

I have found that I may use the disc described. above to retain tobacco and ashes in a partly smoked pipe. The ashes which remain above the burning tobacco act as an excellent insulator, which is effective to prevent burning of the paper disc for the short time that the tobacco continues to burn. The lack of oxygen in the closed pipe bowl assures prompt extinguishment of the smoldering. While I have declared that cardboard of a well known type and cut into the proper shape may be used for closure members in burning pipes, it is Within the contemplation of my invention that I may use a non-combustible or a poorly combustible material such as asbestos paper of a desired thickness or combinations of asbestos paper and a combustible paper. I may also use a wood or linen pulp paper which has been so highly compressed that it has a high resistance to heat.

While I have described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the exact examples declared, but I may make modifications or improvements thereof without departing from the spirit of the invention.

I claim:

A pipe comprising a bowl, a lining covering the inner surfaces of said bowl, an annular groove in said lining spaced from the top edge of said lining, a substantially fiat imperforate disc of less peripheral extent than said groove adapted to have a seal in said groove, and a tobacco filling in said pipe exerting an upward pressure upon said disc to effect said seal.
