Description

Aug. 8, 1933. J. c. ENGLAND PIPE Filed Oct. 14, 1931 wwam auocmq Patented Aug. 8, 1933 UNITED STATES PATET OFFICE Application October 14, 1931.

2 Claims.

The invention relates to stems for pipes, cigar and cigarette holders, and has for its object to provide within the stem a plurality of frusto conically shaped members, through which the smoke passes and which frusto conically shaped members collect and discharge saliva and moisture forwardly, thereby preventing the same from entering the mouth of the smoker.

A further object is to provide an insertable bushing in the stem having its longitudinal passage therethrough, one end of which discharges into the inner frusto conically shaped member for the saliva removing operation, as the smoke passes through the stem.

A further object is to provide the discharge end of the bushing port, and the discharge end of the frusto conically shaped member with flared portions whereby as the smoke passes through the same, it will be discharged outwardly, allowed to expand so that the condensation will gather on the inner peripheries of the conically shaped members before again being discharged.

A further object is to provide the bushing with a forwardly extending reduced portion extending into a forward chamber of the stem and a chamber rearwardly of the bushing in the stem, and in which chamber saliva and moisture is collected.

A further object is to provide means whereby said bushing may be easily removed from the stem when said stem is separated.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth. shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a vertical longitudinal sectional view through the stem showing the same in connection with a pipe.

Figure 2 is a vertical transverse sectional view taken on line 2-2 of Figure 1.

Figure 3 is a vertical longitudinal sectional view through a stem showing a modified form of stem.

Referring to the drawing, the numeral 1 designates the forward portion of the stem and 2 the rear portion. The stem is shown in connection with a pipe bowl 3, however it is to be understood that the stem may be used in Serial No. 568,819

connection with a cigarette or cigar holder if desired.

The stem section 1 is provided with a chamber 4, into which the tapered end 5 of the removable bushing 6 extends. The bushing is provided with a reduced portion 8 of a different size and the portion 9 which extends into the chamber 10 of the stem section 2, so that the bushing can not be placed in the stem with its ends in reversed position, as the reduced rearwardly extending portion 11 of the bushing may be of a different length than the forwardly extending portion -5, for instance as shown in figures 1 and 3. Extending longitudinally through the bushing and its portions 5 and 11 is a passage 12, through which smoke passes. Disposed within the chamber 10 of the stem section 2 are frusto conically shaped baffle members 13 and 14, one within the, other, and into which members the smoke is discharged from the port 12, and which bafiie members collect moisture, and as their small ends are rearwardly disposed, saliva is prevented from passing to the bowl of the pipe or to the cigar or cigarette if the same is used in that form. There is a certain amount of moisture from the smoke, and this collects on the inner walls of the bafile members 13 and 14, and flows into the chamber 10, therefore it will be seen that saliva or moisture is positively prevented from entering the bowl of the pipe and collected in the chamber Where it can be easily removed. Baffle member 13 is connected on the portion 11 of the bushing by spacing members 15, while baffle 14 is held in position frictionally by its cylindrical shaped portion 16 in the chamber 10.

Referring to Figure 3 wherein a modified form is shown, in this form the rear end of the smoke passage 12 in the bushing is provided with a flared discharge portion 12a, and the rear ends l of the bafile members 13 and 14 are provided withfiared portions 13a and 14a. By providing the flared discharge ends, the smoke column which has been contracted, as it passes through each member, is allowed to expand rapidly as it is discharged so that it will engage a relatively large surface of the baiile member and the chamber wall at 10a for the collection of moisture from the column of smoke before it is again contracted and allowed to expand. When it is desired to clean the pipe the bushing is removed, and as the bushing is connected to the frusto comically shaped member 13, by the post 15 and to the member 14 by means of the post 15a, it will be seen that the device may be removed from the stem as a unit, for cleaning purposes.

From the above it will be seen that a stem is provided for smoking devices, which is simple in construction and one wherein saliva, moisture and products of combustion will be positively collected in chambers of the stem so that it will not reach the tobacco or the mouth of the operator. It will also be seen that the device may be cheaply manufactured and sold.

The invention having been set forth what is claimed as new and useful is:

1. The combination with a pipe stem having a chamber therein, a bushing in said chamber and having a smoke passage therethrough, said bushing having a rearwardly extending tapered end, of a baffle member within the chamber of the stem, said bafi'le member comprising a plurality of frusto conically shaped members, one within the other and axially disposed in spaced relation to each other, chambers extending entirely through said frusto conically shaped members and a cylindrical portion carried by one of said frusto. conically shaped members and surrounding in spaced relation the rearwardly extending tapered portion of the bushing.

2. The combination with a rearwardly extending bushing having an end and a smoke passage therethrough and rearwardly tapered within a chamber of a pipe stem, inner and outer frusto conically shaped axially alined spaced baflle members within the chamber of the pipe stem, spacing posts between said baffle members and the bushing end, the outer bafiie member having a forwardly extending cylindrical portion surrounding the bushing end and tightly engaging the inner wall of the stem chamber, said baflle members having rearwardly tapered smoke passages therethrough.
