COMBINED FAN AND ALARM SIGNAL.

Specification of Letters Patent.

Patented Jan. 15, 1918..

Application filed September 9, 1913. Serial No. 788,927.

To all whom it may concern: l V

Be it known that I, HERBERT HASTINGS, a citizen of the United States, residing at Brighton, in the county of Monroe and State of New York, have invented a new and useful Combined Fan and Alarm-Signal, of which the following is a specification.

My invention relates more particularly to fans and alarm signals as may be used on automobiles, the former for directly or indirectly cooling the engine and the latter as an alarm signal to indicate, at the will of the operator, the approach of the automobile, and the objects of my invention are first, to combine these two mechanisms into one unit; second, to utilize the rotation of the fan for vibrating the diaphragm of the signal; third, to obtain greater power than is practical to obtain in the present electric horns and thereby a louder signal or one of more volume of sound; fourth, to provide means for varying the volume of sound at the will of the operator. The objects in the spirit of the invention may be attained in many different arrangements and combina tion of parts. I show however the construc tions and combinations illustrated in the drawing in which Figure l is a partial sectional view through the axis of a device embodying my invention, by which I show a construction in which the vibrating diaphragm and sound amplifying horn revolve with the fan element. c

Fig. 2 is a partial sectional view through the axis of a device embodying my invention by which I show a construction in which the vibrating. diaphragm and sound amplifying horn are stationary with respect to the fan element.

Fig. 3 is a view in elevation looking at the front or right hand head of the fan drum of Fig. 2 showing apertures to. facilitate the issue of sound from the alarm.

Fig. 4 is a partial view in perspective showing the slotted end of the hollow axle of Fig. 1. c

Fig. 5 is a partial View in perspective showing the flattened head end, with teeth thereon, of the vibration-producing element of Fig. 1.

Like numbers refer to like parts in the different views.

In Fig. 1, 1 is the bracket or arm which supports the assemblage, usually between the front of the engine and the rear of the radiator. This arm is pierced at its upper end to receive the stationary hollow axle '2 which has an enlarged end 2 slotted transversely at 2 to receive the flattened head 6 of the vibrator stem 3 to prevent the latter from turning. The axle is threaded at 2 and 2 to receive the nuts 4: and 5 respectively and the lever (i is also fitted to the threaded end 2. The nut 4; serves to draw the bearings of the revolving element into proper adjustment against the head 2 of the axle and also serves when so adjusted, as a shoulder on the axle which the tightening of the nut 5 draws against the face of the arm 1 thus clamping the axle 2 securely in position on the arm. The lever 6 has an elongated hub portion 6 which is threaded internally to receive the adjusting screw 7 and the latter is provided with a check nut 8 to secure it in adjusted position in the lever. The screw 7 is also threaded internally to receive the threaded end 3 of the vibrator stem The threads 2 and 3 are right and left hand, and as the lever (3 caused to turn on'the threads 2 of the axlethese threads give it axial motion, and since the vibrating stem 3 is held from rotation the threads within the screw 7 engaging with the threads 3 of the vibrating stem 3 also give this stem axial motion which is the sum of the axial movements caused by the threads within the lever and the threads upon the stem. This axial movement ,of thevibrator stem is for the purpose of bringing the projecting teeth 3 provided 'on the head end thereof into and out of engagement with the projections on the shoe or vibrating block 9 which in turn is secured to the vibratingdiaphragm 9. Supported by suitable bearings on the hollow axle 2 is the fan body 10 which is provided with a belt pulley portion 10, a flange 10 to guide the belt on one side, an offset flange l0 with the three-fold purpose of guiding the belt on the oppositeside, of forming one side of the sound box of the signal and of providing a flange against which the vibratory diaphragm 9 is held by being clamped between it and the flange 11 of the horn 11 by the screws 12 which also pass through the flange 13 of the fan blades 13. It will thus be seen that while the fan is rotating the dia phragm of the signal rotates with it but normally out of contact with the vibration producing element except as the latter is brought into contact by operating the lever (i and operating this lever more or less will vary the volume of sound by causing the diaph 'agm to have greater or less vibratory motion.

In Fig. 2 the stationary axle 2 is secured in the supporting arm 1 by the nut 5 which is threaded to the end'thereof, the tightening of this nut drawing the axle collar 2* back toward the support, drawing the sound 'box 14: against the spacing collar 15 which in turn bears against the inner member of the bearing 16 and binds these parts securely against the arm 1'. The outer member of bearing 16 is mounted in the rotating head 17, to which is secured the vibration producing ring 18 which is provided with projecting teeth 18 which contact with the pin 19 which is supported in a suitable bearing in box It and is normally held out of contact therewith by the expansive pressure of a coil spring which surrounds the small diameter and presses against the shoulder oi the head portion 19 thereof; this pin is projected -into contact with the teeth 18" by pulling the lower end of the lever 20 which is pivoted in suitable bearings on the arm 1, to

tion 23 transmits the vibration to the vibrating diaphragm 24 to which the shoe 23 is secured; the diaphragm 24: is held at its :outer diameter between the flange 14: of the stationary sound box let and the flange 25 of the amplifying horn 25 by the screws .26.

' Secured to 'tlielrflange 17*"- of the head 17 is the tan body 27 which is provided with belt flangesQT and 27", the flange 27 to which the fan blades 28 are secured and the perforated head portion 27 with openings E, and the hub27 in which is held the outer member of the anti-friction bearing 2-9 the inner member of which is mounted on the small end of the axle 2 and on this small end are threaded the check nuts 30 which provide adjustment for proper running condition of the .bearings 16 and 29. It will thus be seen in said support.

means for moving that the sound producing element is normally inoperative and stationary with respect to the revolving tan and vibration producing ring revolving therewith but that contact may be made between the latter and the sound producing element at. thewill ot' the operator. =1

I am awarethat prior to my invention alarm signals have been made with vibrating diaphragm and that fans have beenmade journaled on a stationary axlesecured to a supporting arm] I do not therefor'e claim either of these broadly but Iclaim l.'In a signal the combination of a re -volving tan, a diaphragm mounted on the fan and rotatingtherewith, means to vibrate said diaphragm consisting of a projection on said diaphragm and a striking device "for striking said projection, a spindleon which said fan is mounted to rotate, a stem movable endwise through said spindle, said striking device being carried on the end of said stem and-being movable thereby into and out of engagement with the projection on said diaphragm.

2. In a'signal, the combination of'a tubular support, a horn mounted to rotate about said support, a diaphragm circumferentially supported in saidhorn, projections on said diaphragm, a stem mounted to move longitudinally through s'aidsupport to engage with the projections on said diaphragm, and means for moving said stem longitudinally In a signal, the combination of a tubular support, a tan mounted to rotate about said support, a diaphragm circumferentially supported in said fan, projections on said diaphragm, a stem mounted to move longitudina'lly' through said support to engage with the projections on said diaphragm, and said stem longitudinally in said support. I

4. In a signal, the combination of a'tubular support, a hornmounted to rotate about said support,a diaphragm circumferentially supported in said horn, a projection on said diaphragm and a stem mounted to move longitudinally through said support to engage with the projection on said diaphragm.
