Sept. 6, 1938. J. E. GROULX SCREEN FOR TOBACCO PIPES Filed Oct. 21, 1937 INVENTOR. 0 n.6 01/ )0. BY M% Wm ATTORNEY.

Patented Sept. 6, 1938 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to screens, and more particularly to a screen adapted to be inserted in the bowl of a tobacco pipe for holding the tobacco clear of the stem opening and prevent fine particles of tobacco being drawn into the mouth of the smoker, and/or prevent the stem from clogging.

One of the prime objects of the invention is to provide a very simple, practical, and inexpensive screen for tobacco pipes which is efficient in operation, which holds the tobacco clear from the bottom of the pipe bowl, preventing saliva saturated tobacco particles being drawn into the mouth, and also from plugging or clogging the passage through the stem and through which the smoke is drawn.

A further object is to provide a screen for tobacco pipes which prevents the saliva from saturating the tobacco in the bowl, thus avoiding the strong taste and odor usually experienced near the end of a smoke.

Another object is to provide a screen for tobacco pipes which can be very easily and economically manufactured and assembled, and which is resilient and expandable so that it is adaptable for pipe bowls of varying inside diameters.

The above and other objects will appear as the specification progresses, reference being had to the accompanying drawing in which I have 30 shown the preferred embodiment of my invention, and in which like reference numerals indicate like parts throughout the several views thereof.

In the drawing:

Fig. 1 is a side elevational, part sectional view of a conventional pipe showing my pipe screen in position.

Fig. 2 is an enlarged detail edge view of the device.

Fig. 3 is a top plan view.

Fig. 4 is an inverted plan View.

Referring now more particularly to the drawing in which I have shown the preferred embodiment of my invention, the numeral 8 indicates a pipe of conventional design, including a stem 9 in which a smoke duct or passage I0 is provided as usual, this smoke duct opening into the bowl of the pipe, at the bottom in the usual manner.

The device is adapted to be inserted in the 50 pipe bowl and is formed of a length of coiled wire II, the ends being secured together to form an endless ring, with the coils so spaced that they may be forced together to reduce the diameter of the ring to suit pipe bowls of difierent sizes.

A fiat screen disc I2 is mounted on and forms a closure for the opening in the center of the coil ring, and can be secured thereto in any approved manner, but I prefer to provide a couple of strands of fine wire l3, bent U-shaped with the legs l4 threaded through the screen, ends being looped around and secured to the coil II at diametrically spaced-apart points, this fiat screen serving to hold the tobacco above the bottom of the bowl of the pipe, therefore no fine particles can become soggy and adhere to the bowl or be drawn into the stem, so that the pipe will draw well and clean easily, as there will be no damp particles to adhere to the bottom and side walls of the bowl.

The flat screen can be made up in any desired manner, it can be cut or stamped from a large sheet, or it can be woven to disc shape, if desired, this however, is a matter of choice, and I do not wish to be limited to any particular construction or design.

The manufacture is very simple and economical; the ends of a length of coil spring are first secured together to form a ring, the disc I2 is next mounted on the ring by means of the fastening wire l3, the ends of the wire are then secured to the coils, and the device is assembled and ready for use,

In practise the device is inserted in the bowl of the pipe and is pressed down to the bottom of the bowl, the pipe is then filled with tobacco in the usual manner, and is then ready to smoke. The spacing of the tobacco from the bowl provides for a clean, sweet smoke, and the pipe will draw very easily. It will also be apparent that the screen is readily removable for cleaning or any other purpose, it is merely necessary to tip it in the pipe bowl and it can then be easily removed.

From the foregoing description it will be clearly obvious that I have perfected a very simple, practical, and inexpensive screen for tobacco pipes, which can be very economically manufactured and assembled.

What I claim is:

1. A screen for a tobacco pipe comprising an endless coil spring forming a ring of predetermined diameter, and a flatscreen mounted thereon and forming a cover for said ring.

2. A tobacco pipe screen of the class described comprising an endless coil spring forming an expansible and contractible coil ring, a fiat screen mounted thereon and covering the opening in said ring, and means for securing said fiat screen in position without interfering with the expansion or contraction of said structure.

3. A device of the character described comprising an endless strip of coiled spring forming an expansible and contractible ring adapted to be inserted in the bowl of a tobacco pipe, and a flat screen mounted on said ring and forming a closure for the opening in the ring.

4. In a device of the character described com prising'a strip of coil spring secured together at its ends to form an endless expansible and contractible coil ring, a perforated disc mounted on said coil and forming a cover for the opening in said coil ring, and strands for securing said cover 5 to said coil at spaced-apart points.
