EXHAUST-WHISTLE FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Application filed February 3, 1921. Serial No. 442,141.

To all whom it may concern:

Be it known that I, EDGAR L. CRUISE, a citizen of the United States, residing at Keystone, in the county of McDowell and State of West Virginia, have invented certain new, and useful Improvements in Exhaust-VVhistles for Motor-Vehicles, of which the following is a specification.

This invention relates to whistles of the chime type, and the primary object of the invention is to provide an improved whistle particularly adapted for use on motor ve hicles and arranged to be operated by the exhaust gases of the internal combustion engines thereof, the whistle being so constructed that the collecting of dirt on the same will be prevented-and the depositing of carbon therein eliminated to a great extent.

While an exhaust operated whistle is particularly desirable by motorists, the prac tical commercializing of this type of whistle has been prevented owing to the fact that the whistle soon becomes clogged by means of dirt collecting thereon owing to its position underneath the car and the collecting of carbon from the engine and the fact that the whistle could not be readily and easily cleaned.

It is therefore another object of the invention to provide a guard member for preventing the settling of dust, road grit and the like on the whistle, which also act'sas a horn for amplifying the sound. A further object of the invention is to provide a whistle which embodies a' few readily detachable parts, which can be conveniently and easily cleaned.

A still furtherobject of the invention. is to provide an improved. whistle of the above character, which is durable and eflicient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

1th theseand other obyects in view, the invention consists in the novel construction,

arrangement and formation of parts, as

will be hereinafter more specifically described, claimed and illustrated in the. accompanying drawlngs, forming a part of this specification, in which drawings:

Figure 1 is a side elevation of the improved whistle.

Fig. 2 is a similar view with the horn or guard member removed therefrom.

Fig. 3 is an end elevation of the improved whistle.

Fig. 4 is an opposite end view of the improved whlstle with the horn or guard member removed.

Fig". 5 is a longitudinal section through the improved whistle.

Fig. 6 is a diametric section through the whistle taken on the line 66 of Fig. 5.

Fig. 7 is a detail perspective view of the reed or tongue of the whistle.

Fig. 8 is a detail elevation of the cap plate for the end of the bowl or whistle tube. I

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the body or tube of the whistle; B, the end cap plate therefor G, the reed or tongues for the tube; D, the'whistle connection and E, the improved horn or guard member.

The body or tube A of the whistle includes a tubular casing 10, which has been shown circular in cross section, and the outer end of this casing is arranged in stepped relation as at 11, 12, 13and' l4, and each one of the stepped portions constitute substantially a quarter of a circle. The tubular casing 10 is divided longitudinally by bisecting partition plates 15 and lewhich form compartments 17, 18, 19 and 20 and these partition plates. go to the various stepped portions of the outer end of the casing so as to form the chambers of diiferent lengths, so as to form different pitches or tones for the whistle. The cylindrical casing 10 adjacent to its inner end and at each one of the compartments, 17 18, 19 and 20 is provided with a cut-out portion 21 which forms the bowls for the whistle.

In order to close the outer ends of the chambers 17, 18,19 and 20, the cap plate B is provided, and as shown this plate includes a longitudinally extending flat plate 22 which is provided with the laterally extending portion 23. This laterally extending portion has its upper and lower ends bent inwardly to provide respectively the cover plates 24 and 25, which are adapted to close the ends of the compartments 18 and 19'. The upper and lower ends of the plate 22 have their terminals bent in opposite directions to provide , cover plates 26 and 27 for the chambers 20 and 17 respectively. If

so desired, the inner edges of the cover plate 2? and 25 and the cover plates 24 and 26 may be connected by side rings or plates ments may be provided with integral cover plates if so desired. As shown the cap plate B is held in position by means of nuts 30. which engage the flexible washers 31. The nuts 30 and washers 31 are carried by the inner surface of the cover plates 24, 25, 26 and 27 and are adapted to be engaged by headed screws 32, the heads of which extend exteriorly of the whistle body. It can be seen that by adjusting the screws 32, the nuts 30 will be forced into engagement with the'compressible gaskets 31, which will force the same into intimate engagement with the side walls of the I'QSP- BCtli chambers 17, 18, 19 and 20 of the whistle body, and thus elfectively prevent the displacement of the cap plate B therefrom.

The reed C for the whistle body includes a flat plate 33 substantially square shaped in plan, which has integrally formed therewith the upstanding flexible tongues 34:. As shown, the tongues are four in number and have their longitudinal edges separated from each other, and these tongues are adapted to be inserted into their respective compartments and extend diagonally across the same, and terminate adjacent to the lower edge of the bowls 21 of the compart ments. The reed C is held in position by means of a bolt 35 which is rigidly carried by the partition plates at the inner ends thereof and this bolt has its Outer end threaded and is adapted to be extended through an axial opening 36 formed in the square plate 33 of the reed C. After the bolt 35 is inserted through the opening 36, a suitable retaining nut or the like 37 is provided for the bolt, so as to firmly hold the reed in position. The inner end of the whistle body A may have secured thereto in any preferred manner, the exteriorly threaded collar 38. The outer edge of this collar is provided with an outstanding annular flange 39 which forms a seat for the horn E as will be hereinafter more fully described. The exteriorly threaded collar 38 is adapted to receive the connection D of the whistle, and as shown this connection D consists of an annular body 40 having the internal threads ll'formed therein, for engagement with the external threads of the collar 38. The outer end of the bore of the body is reduced in diameter and provided with internal threads 42 for the reception of the branch of the exhaust pipe of the internal combustion engine (not shown). The outer surface of this portion. of the body is preferably formed polygonal in cross section as at 43, so as to form a nut face, whereby the same can be readily engaged by a wrench or the like.

The horn E forms an important part of the invention, as the same performs the dual function of forming a guard for the body 10 to prevent the passageways or bowls 21 from becoming stopped up from road grit, oil and the like, and also for augmenting the volume or tone of the whistle. As shown the horn E includes the frustoconical body 50, the inner tapered end of which is provided with the inwardly extending annular attaching flange 51. The inwardly extending annular flange 51 is adapted to seat upon the flange 39 and the outer surface thereof is engaged by the inner edge of the connection D, which firmly holds the horn E in position. If so desired, the outer flared end of the horn E maybe provided with a peripheral outstanding flange 52, which serves as a reinforcing rib for the body of the born.

The body 50 of the horn E may be provided adjacent to its inner end with a plurality of openings 53, through which the sound wave may escape.

The improved whistle maybe made up in any preferred manner and of any preferred material, but it is preferred that the whistle be wholly constructed of aluminum or some other similar light material.

In operation of the improved whistle, the connection D is arranged on the exhaust pipe or branch thereof, in any preferred manner, and it can be seen that the exhaust gases will flow through the connection D and be spread outwardly by the flat plate 33 of the reed G into the various compartments, where the same will engage the tongues 34 and then flow out through the bowls or cutout portions 21. As stated the compartments 17, 18, 19v and 20 are of different lengths which form different pitches or different tones. The horn suitably augments the volume of the sound and completely houses that portion of the whistle which is provided with the bowls or outlet openings 21.

Changes in details may be made without departing from the spirit or scope of this invention; but,

I claim:

1. A whistle comprising a hollow body having a plurality of different length chambers formed therein, fluid escape ports formed in the, body communicating with each one of the chambers, and a reed including a plurality of flexible tongues arranged in the body with one tongue in each chamber, the terminals of the tongues ending adjacent to the inner wall of said ports.
