TOY SIREN WHISTLE I Filed Aug. 1, 1933 INVENTOR ATTORNEYS 7, as of Fig. 1.
atented Apr. 24, 1934 TOY SIREN WHISTLE John Lauterbach, Utica, N. Y. Application August 1, 1933, Serial No. 683,111
6 Claims.
My present invention relates to a toy siren whistle or a siren whistle adapted to be operated by the person blowing into it as distinct from a power or steam-operated factory whistle or signal whistle.
lhe purpose of this invention is to provide a siren whistle oi the class described which is of new, improved and efficient form and which is economical in manufacture, readily assembled, 10'
reliable and durable in use and not apt to get out of order nor to become silent in use.
A further purpose is to provide a siren whistle of the class described which is formed of a minimum of parts, but having those parts so shaped and so combined with each other as to be rotated and put into operation with a minimum of lung power from the person and further where the rotor is so formed and combined with the other 7 M parts that the force of the air blown into the 20 mouthpiece of the whistle does not operate to retard the movement of the motor nor change its position lengthwise of the whistle so as to prevent the device from being operative.
A still further purpose is to provide the parts of the whistle of such construction that the air blown into the whistle is diverted outwardly against slanting slots provided in the sides of the rotor so that the force of this current of air produces the necessary rotation of the rotor, but without the rotor being subjected to any appreciable longitudinal pressure and so that any friction or wear from longitudinal pressure of the rotor in its bearings is reducedto'a minimum.
Further purposes and advantages of this invention will appear from the specification and claims herein.
Fig. 1 is a side elevation of a toy siren whistle embodying this invention, the whistle being shown in somewhat larger size than the preferred size of the whistle.
Figs. 2, 3 and 4 are respectively side views of the casing, the rotor and the block which block constitutes the combined mouthpiece clos- U ing diaphragm andslotted cage. 45'
Fig. 5 is a central longitudinal sectional view on line 55 of Fig. 1.
Fig. 6 is a perspective view of the rotor on a somewhat enlarged scale.
Fig. '7 is an elevation of the left hand end of the rotor as seen in Fig. 3.
Fig. 8 is a right hand end view of the block shown in Fig. 4.
Fig. 9 is a transverse sectional view on line Referring to the drawing in a more particular description, it will be seen that as already mentioned the toy whistle shown in the drawing consists of the three main parts, namely a casing 10, a rotor 11 and a block 12 which latter part 7 consists of a closing diaphragm 13, a cage 14 005 and a mouthpiece 15. For convenience in manufacture, usually the diaphragm 13 and the cage 14 are formed in one integral piece and the mouthpiece 15 is iormed originally as another piece, but is permanently assembled into a proper aperture of the diaphragm as it does not need to be removed from the block for assembling or taking apart the Working parts of the whistle.
Preferably, but not necessarily, the several parts of the whistle will be formed of a synthetic rezinoid material which substance lends itself to the commercial forming of said parts by a molding process with sufiicient accuracy to allow the parts to be thereafter assembled with a minimum of any finishing or fitting labor.
The casing 10 is conveniently and preferably formed as a circular tube-like member preferably slanting from its left hand or open end to be smaller towards its bridged or partly closedright hand end. This closure at the right hand end is preferably formed as a bridge-like member on account of this end closure being provided with a plurality of air escape holes 16 spaced about the closure, but with the remaining part of the closure forming a bridge from which there projects from its central part inwardly a post 17 on the left hand end of which as the parts are seen in the drawing there is provided an axially arranged socket 18 forming the bearing for the end of the spindle of the rotor hereinafter mentioned. For convenience in carrying and handling the whistle this bridge-like end of the casing is provided with an outwardly extending boss 19 in which is formed a transverse hole 20 in which may be mounted the ring 21.
The larger or left hand end of the casing 10 as the parts are seen in the drawing is provided with an internal screw-threading to receive the exterior threads of the closing diaphragm 13 of the block 12. This block 12 is of circular form Mill and preferably to the left of the screw-threaded portion the diaphragm is provided with an outwardly projecting flange 22 which serves to stop the threading in of this block into the casing at the proper point in the assembling of the parts so as to hold the rotor 11 securely in position, but loosely enough so as to allow it to rotate very easily. p I
The outer part of this block is provided with a central aperture adapted to receive the inner end 1 tion of the rotor.
of the mouthpiece 15 assuming as already stated that the mouthpiece will be formed as a separate piece. Projecting into the main cavity of the casing IOfrom the diaphragm 13 there is provided the cage 14 having a plurality of the slots 23 in its side for directing the air to the slots 24 of the rotor 11. Preferably as best shown in Fig. 9 these slots 23 will all slant in one direction instead of extending radially from the center of the cage. The inner end 25 of this cage is formed as a cone with the smaller part of the cone extending outwardly; that is to the left as the parts are illustrated for instance in Fig. 5. The left or outer face of this cone-like end forms a means for diverting outwardly equally in all directions the current of air coming from the mouthpiece and which is to be directed through the slots 23 of the cage. The inner or right hand face of the conical shaped end 25 forms a bearing for the inside spindle 26 of the rotor 9.
The rotor 9 is in the main a cup-shaped member from the bottom or disk 27 of which there extends to the right or towards and into the bearing 18 the spindle 28 and from the inner or left hand side of the bottom of said rotor there extends the relatively shorter spindle 26 to engage the socket or hearing provided in the recessed side of the cone-shaped end of the cage 14. Through the side of this cup-shaped rotor there are provided a plurality of outlet slots 24. These slots slant all in one direction instead of being radial so that the current or air directed through the various outlet slots 23 of the cage 14 tend to and actually do start a rapid rotation of the rotor 11. Assuming as will preferably be the case that the slots 23 of the cage also slant, then the slots 24 will slant in the opposite direction as appears from Fig. 9 in orderto obtain as much power as possible from the air currents to cause said rotation of Figs. 3, 5, 6 and '7, the slots 24 of the rotor do not extend all the way through the side wall of the rotor at the extreme left hand end of the rotor, but a slight amount of material as at 29 is left connecting the adjacent sections of the side wall of the rotor. This detail results in strengthening the rotor against accidental breakage in assembling or use and does not interfere with the separate currents of air passing through the slots 23 toward the slots 24. From an inspection of Figs. 5 and 6 it will be seen that the two spindles 26 and 28 of the rotor are mounted in the axially aligned bearings provided therefor, the first in the recessed cone end 25 and the longer spindle 28 in the bearing 18 of post 17. These bearings carry the rotor with the minimum of friction at the engaging parts thereof and also eliminate any friction between the inner face of the cup of the rotor and the closely opposing but slightly removed. outer surface of the cage. Due to the outlet slots 24 in the rotor being on the sides thereof instead of at the bottom of the rotor, the currents of air directed against the sides of the slots 24 produce a rotating movement of the rotor without any substantial part of this power being operative to push the rotor endwise against either of its bearings. This feature is of great importance because a very slight friction between the rotor and any adjacent parts of the device would be sufficient to retard the prompt motion or the required speeding up of the rotor which would As will be seen from an inspecallow for the assembling of the rotor between the said block and the post 17 of the casing. This also allows a boy using the whistle to have access to the inside for the purpose of cleaning or examination.
