UNITED STATES PATENT OFFICE SMOKING PIPE Cal v. Brown, Richmond, Calif.

Application August 23, 1944, Serial No; 551,500 2Cla-ims. (on. 131492) This invention relates to improvements in tobacco pipes and has particular reference to the construction of the stem portion thereof.

The principal object of the invention is the provision of a tobacco pipe stem so devised that the stern may be readily folded or nested over the top of the pipe bowl, thus providing a com pact pipe arrangement that can be readily carried by the user, with the pipe occupying but a minimum amount of space in the users pocket.

A further object of the invention is to provide a jointed pipe stem that can be easily cleaned, thus rendering the same highly sanitary.

Another object of the invention is to produce a smoking pipe of the character described that is simple in construction, strong and durable, yet light in weight, and unusually compact and high-- ly efficient in use.

All of the aforementioned and still other objects and advantages of my invention will become apparent from a study of the following specifications, taken with the accompanying drawing where like characters of reference designate corresponding parts throughout the sev eral views.

Fig. 1 is a longitudinal side elevational View of one type of smoking pipe embodying the invention;

Fig. 2 is a central, vertical, longitudinal, sectional view of the smoking pipe;

Fig. 3 is an exploded, sectional, horizontal view of a pair of members that form one of the jointed portions of the pipe;

Fig. 4 is an especially constructed bolt and nut employed for hingedly securing the jointed portions together;

Fig. 5 is a top plan view of a pair of members that form one of the jointed portions of the pipe;

Fig. 6 is a side elevational view of the pipe, showing the stem in folded position;

Fig. '7 is a detail view in elevation of one of the halves that forms a jointed portion;

Fig. 8 is a view in perspective of the pair of members of Figs 3 and 5, as assembled.

Referring in detail to the drawings the numeral 9 designates the bowl of an ordinary pipe and the numerals lil designate a bolt having a slotted head I i, said bolt serving to retain the hinged sections of the pipe stem together. The numeral l2 designates a female spacer coupling member that is interposed between the jointed members l4, said jointed members, spacer and mouth piece l3 having a smoke passageway I5 that leads from the bowl. The jointed members l4 are constructed of mating halves I4 and 14" as illustrated in Figs. 3 and 5, each half being formed with a hole It that is provided to accommodate the bolt ll) which functions to hingedly secure the halves together. Each of the halves l4 and 14 forming the jointed member I4 is formed at one side with an extension l9, which is substantially semi-circular in cross section and is provided with a flat inner face 22. The other side of the extension i9 is cut away to provide a concave face 23 which merges at its lower end into a relatively thin stop wall 2|. The concave faces 23 of each of the halves interfit with and act as bearing surfaces for the respective extensions I9, during the pivotal folding movement of the parts. The numerals l1 designate male portions that are formed on each end of the jointed members l4 and which are capable of extending into female portions formed into the bowl piece 9, coupling member I2 and mouth piece l3 whereby the various parts forming the pipe and stem are removably secured together. The numeral 18 designates the inner portion of the bowl 9, the smoke passageway I5 leading therefrom through the jointed members and around the bolts I0, each bolt having a threaded nut 24 for holding it in position. The number 20 designates a bevel surface on the member M and the number 2! an extension thereon. When it is desired to fold the pipe, it is apparent that the stem I3 and coupling member 12 will be turned upwardly so that the stem will closely overlie and be substantially parallel to the top face of the bowl 9. During this pivotal movement of the stem and coupling members, the extensions IQ of the halves I4 and M will slide over the respective concave bearing surfaces 23, and, at the completion of the folding, the bevelled faces 20 on the upper ends of the halves I4 and M" will abut one another, as best shown in Figure 6.

From the foregoing description taken in conjunction with the accompanying drawings it will be apparent that the invention possesses certain unique features of construction, whereby the various parts forming the stem are removably and without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A smoking pipe embodying in its construction a bowl portion and a stem portion, the stem portion comprising a pair of jointed members adaptable for pivotal movement, an intermediate spacing member, and a mouth piece, the jointed members being formed with opposed male end portions and the intermediate spacing member with oppositely opposed female end portions whereby the jointed members are removably secured together, the spacer member being of such length relative to the height of the pipe bowl as will enable the stem to be folded atright angles and a portion thereof extend in parallelism over and in proximity to the top face of the bowl.

2. A smoking pipe embodying in its construction a bowl portion and a stem portion removably secured thereto, the stem portion comprising a pair of jointed members, an intermediate spacing member and a mouth piece removably secured to one of the jointed members, each jointed member being in two parts, said parts comprising mat- 0 Number REFERENCES CITED I The following referenlces are of record in the file of this patent:
