Applieationgfiled March 8, 1920. Serial No. 363,920.

To all whom it may concern Be it known that I, HARRY BALTHAsAR a citizen of the United States, residing at the city of St. Louis, in the State of Mis souri, have invented certain new and useful Improvements in i i histles, of which the following is a specification. I 1

This invention is awhistle for motorvehicles, and belongs to what is known as the compression-type of whistle, being operated from the compression in one of the. cylinders in the engine, instead of from the exhaust.

Its especial advantages cheapness in manufacture, facility in cleaning, ease in 013 eration, and reliability.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever. they occur, i

Figure 1 is a side elevation showing the whistle attached tov a cylinder-head, in the place of an ordinary priming-cup, such priming-cup being removed for that purp Figure 2 is a front elevation;

Figure 3 is a sectional view on the'line 3-3 in Figure 2;

Figure 4 is a detail of a plate for adjusting the volume or" sound from the whistle; and

Figure 5 showsa modification, in which a pair of slidable members is used.

By the threaded nipple 1, this device, as a whole, is attached to the cylinder-head 2. For the sake of convenience, this may be by removing one of the priming cups, but, if desired, may be through a separate hole.

The operating cord 8 leads to the drivers seat, and may, if desired, be attached to the steering-post (not shown); or atany other suitable point. At its other end, the said cord is fastened in the hole 1 in thebelle crank 5, pivoted at 6 to lugs 7 projecting from the valve-casing 8.

The gas passes out of the cylinder through passage 9 into chamber 10, he wall of which 7 on one side is provided with valve-seat 11 opposite hole 12 normally closed by the hexagonal nut 13.

Valve 14 seatsupon valve-seat 11 and controls the exit of gas from chamber 10.

Valve 14; is kept normally closed by'spring 15 or any other suitable spring, and is opened by the pressure of nose 160tbell-crank' 5 reversed or other means of union of the two when the said bell-crank 5 is rocked on pi t 6 by apull upon the cord 3.

Then valvelt has thus been opened, the rushes through opening 17 into chamber 8 nd thenceithrough the restricted port 19 n a d past thethroat 2001" the whistle. Throat i v s formed ina hollow casting 21, which, I

for. the sake of easier'casting, is formed with the opening 22. Opening 22 is closed by a cap23 by upsetting the edge 2 of the said cap. .65

.Nut 13 is easily removable for the purpose otcleaning chamber 10 or passage 9.0r for the purpose of taking'out valve 1 1 for regrinding or. for the purpose of cleaning valve-seat 11. s V Member 21 is formed with a flange 25, preferably internally screw-threaded. Valve-casing 8 is provided with a collar 26, preferably externally screw-threaded, whichv screw-threads on collar 26 and within flange 25 serveto unite valve-casing 8 and hollow member 21 .together.- Theorder of the screw-threading of the said parts may be parts provided. M

The plate'27 contains the slot 28, and is attached by the'screw 29 to the member 21. It may be attached to the casting21 either onthe outside, as shown in the drawings,or upon the inside thereof, as not shown in the drawings, or, as further not shown in the drawings, it may be fastened in a groove in the wall of casting 21. Another form not shown in the drawings, but which maybe substituted'tor the slot and screw, is a groove and screw. For the slidable member 27, a pivoted member (not shown in the drawings) may, likewise, be substituted, whlchmember will swing like a trap-door.

The slot 28 allows the plate 27 to be adjusted in either direction, so as either to reduce the opening ofthe throat 20 or to make it larger, with the object of regulating the volume of tone emitted by the whistle:

either to suit the taste of individual users or to accommodate the same to the amount of compression in the individual engine or cylinderto which this whistle is a tached. s i The modified form shown in Figure 5 con sists 01" a pair of wings 30 and 31, slidably 105 pivoted by the screw 32 to the casting 21. This allows even more accurate adjustment of the size of the opening throughthroat 20.

If desired, both wings and 31 can be closed, as shown in Figure 5, or one of them may be partly or entirely open and the other one partly or entirely closed; The combination of these wings admits of innumerable permutations of arrangements for small or large apertures, and permits nice adjustment to suit any taste or requirement. It, also. prevents the possibility lot hissing through slot 28. The device shown in Figure 5 can be located either inside or outside ot the casting" 21 orin a groove in the same.

Having; thus described this invent o:v hereby reserve the benefit of all chan tts in form. arrangement. order. or use of parts, as it may he made therein without depart ng from the spirit of this invention or the scope of the following claimsv I claim:

1. A whistle of the compression type having a whistle throat and co-operat-ing plates the combination with is evident that many minor changes 3. A whistle of the compression type having awhistle throat and a pair of superimposed cooperating plates having an opening-anchelosing movement with respect to the throat opening for varying the extent of the same.

43:. In a whistle of the compression type.

a casting tachment to an engine cylinder and provided. with a whistle throat. of a pair of pivotally mounted cooperatively arranged plates having adjustment over the throat Opening and being- (a pahle of a relatively open-andshut movement 'iermitting innumerable permutation of arrangement for small or large openings.

In testimony whereof I hGIGHUlZORfiiX- my signature.
