SIREN AND ATTACHING MEANS THEREFOR.

Application filed larch 16, 1925. Serial No. 15,788.

To all whom it'may' concern: I

Be it known that we, Lns'rnn H. MILES and JAMES W. BAYLESS, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a certain new and useful Improvement in Sirens and Attaching Means Therefor, of which the following is a full,

had to the accompanying drawings. I

This invention relates to sirens and attaching means therefor.

The general object of the invention is to provide an improved siren and operating means wherein the artsare simply constructed and are hig ly eflicient.

A further object of the invention is to provide a fixed stator having a rotor movable therein, wherein the parts are of improved construction.

Another object of the invention is to provide a siren together with attaching means wherein the attaching means includes a shaft offset with respect to the axisof the rotor.

Another object of the invention is to pro vide a siren including a rotor and a stator together with a drivingpulley, all arranged in a novel manner.

Another object of the invention is to pro-- vide an improved attaching means for a siren together with a novel operating means therefor.

Another object of the invention is to provide an improved bearing support for the rotor of a siren.

Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings wherein Fig. 1 is a central sectional view through a siren embodying the features of our invention; Fig. 2 is an elevation showing a siren with the cover plate removed;

Fig. 3 is a fragmentary top plan view show ing the offset supportin member; 'Figs. 4 and 5 are fragmentary etails showing the openings communicationg with the cavities in the rotor; Fig. 6 is a plan view of the erefor; Fig. 7 is a side elevation showing the siren. and the operating members; Fi 8- is an enlarged detail showing the portion of the operating member and Fig. 9 1s a sectional view showin a detail of the fastening member.

ferring to the drawing by reference characters, we have shown a siren embodying the features of our invention at 10. This The cover is shown as provided with a horn 16 thereon and across the mouth of this horn we secure awire gauze disc 17 The base member includes a boss'18 which is integral therewith and adjacent the boss 18 but offset with respect thereto, is a holding lug or boss 19. The boss 18 is drilled out to provide an aperture 21 which receives a drive shaft 22. This drive shaft is provided with a shoulder 23 upon which one member of a ball race 24 is fitted while the other member of the ball race 24' is fitted in a rab bet 25 in the boss 18. In a similar manner a ball race 26 is arranged in a rabbet 27 and a dust cap 28 is secured over the ball race 26.

The rotor which is an important feature of our invention, is shown, at 30; This rotor comprises a disc 31 having a peripheral flange 32 thereon and having a hub 33'arranged to fit over the shaft 22. The hub 33 is recessed to save weight and the end there-- of engages the member of theball race 24, which is in engagement with the shoulder 23. A nut 35 serves to hold the parts in theposition described. The other end of the .41 Whlch serves to hold flexible discs 42 adjacent another bearing plate 43 which plate is held against movement by locking nuts 44. The arrangement is such that the bearing assembly is looked upon the shaft 22 thus pre venting vibration and at the same time, the

flexible discs 42 will engage a driving member and are mounted for adjustment'longi. tudinally along the shaft.

' The rotor 30 as reviously stated is ro vided with a peripheral flange 32 whic is connected by means of ribs 45 with the hub 23. The ribs 45 in conjunction with the disc 31 provide a plurality of pockets for receiving air and adjacent the outer end of each pocket a part of the flange 32 is removedto provide passageways 50 for air. The surface of .the flange defines the passageways '50.

which are preferably tapered as at 51. The onter flange 12 of the base member 11 is also provided with slots .54 which correspond in peripheral spacing with the slots 50 previously described. The portions of the flanges orclam'pingmember extends. This clamp- 54 are beveled as at'55v in a manner similar to'the bevel 51 but in a direction reverse The ribs 45, as will be noted by referring to Fig. 1, are cut away at 60to produce a' pocket 61 in front of the horn 161 This. producesfa superior siren and this pocket feature we deem of considerable importance.

The boss 19'is provided with an aperture 62 through which a supporting shaftv 63 mg member is provided with a base 64 which, may have threaded bosses 65 thereon for securing it in place. s

The shaft '63 is provided with upper and lower sliding supporting means shown as collars 66 and 67 whichare held in position by set screws 60. The lower supporting collar has; a ortion thereon engaging the body to maintain the body in proper position. A spring 7 O is interposed between the collar 67 and the upper portion of the boss 19 and the ends of this spring are bent as at 71 to fit within recesses in the boss 19 and the collar 67 respectively.

From the foregoing description it will be apparent that when the base 64 has been .secured in position that. the set-screws 68 may be released and the boss 19 adjusted to proper position on the shaft 63. After this adjustment has been shifted, the supporting means 66 and 67 will be secured in place by the-set screws 68 to hold the siren in operative position.-

' The under surfac'of the. boss 19 is provided with a set screw 75 which is adapted to engage the lower set screw 68 to limit the swinging movement of the base member with respect to the holding lug 19. The spring 70 is so arranged on the shaft that its engagement with the collar 67 and the boss 19 tends to turn the siren with the lower set screw 68 in engagement with the set screw as shown in Fig. 3.

In order to drive thesiren it is preferably mounted with the flexible discs against the fly wheel of a gasoline engine.

The base member 11 is shown as provided with a bracket 81 which has a universal connection 82 thereon. This'connection 82 has a link *83-secured thereto, which passes through a" pin 84, mounted for movement on a ell crank 85 shown in Figs. 8 and 9. The bell crank is adapted to be supported on a shaft 86 and may be rocked by means "of a rod 87 which has a push button 88 thereon. The rod 87 preferably passes through the bottom of the body of the vehicle 89. I

The link .83 extends beyond the pin 84 for some distance and has a spring 90 surrounding it. This spring is retained by a washer 91 which engages a cotter. pin 92.

A cotter pin 93 on the link '83 engages the pin'8'4.

A spring 94 is preferably connected through a bar 95 with the bracket 81 so that it will aid in returning the disc 42 toxinoperative position.

.In Fig. 6 the device is shown in operative position. When'the operator'wishes to sound. the siren he will push upon the*button ,88flthus rocking the bell crank 95'and oansin a compression of the spring 90. This wi l exert'a pull upon the universal joint 82 and will turn the siren about the shaft 63 bringing the disc 42 in engagement with the fly wheel-'80 to rotate the rotor.

Thearrangement including the spring 90 is of extreme importance as regardless of the quickness or amount of forceexerted on thebutton 88 only a predetermined pull can beexerted on the rod, 8j3.thus preventing breakage of parts. I

Referring again to Fig. 1 it will be noted I that the flange 32 of the rotor is in close proximity to the flange of the base member or stator and also that the cover is arranged very close to the outer edge of the ribs 30.

These parts are carefully machined to accurate dimensions and on account of this accuracy, we are able tomake a device which is more simplethan others with which we are familiar.
