ALARM 0R SIGNAL APPARATUS.

Specification of Letters Patent.

Patented Apr. 10, 1917.

Application filed May 19, 1914. Serial No. 839,510.

To all whom it may concern."

Be it known that I, IRA E. STUMP, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Alarm or Signaling Apparatus, of which the following is a specification.

My invention relates to improvements in alarm or signaling apparatus, and is particularly designed and adapted for use in connection with self-propelled vehicle, such as automobiles, motor trucks, and the like, where an air cooling fan is employed at the rear of the radiator and in front of the engine or motor cylinders for directing currents of air over the latter for cooling the same.

The improved alarm or signaling apparatus is particularly designed for use in connection with or as a part of such air cooling fan in givingthe requisite alarm or signal.

The primary object of the invention is to provide a generally improved alarm or signaling apparatus of exceedingly simple, cheap, and eflicient construction, the improved apparatus including a centrally located diaphragm suitably mounted within the hub portion of the fan and adapted to be carried by the latter while being rotated.

With the above mentioned, and other ends in view, the invention consists in the novel construction arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure 1, is a front elevation of an air cooling fan embodying my improved signaling apparatus, a portion of the walls of the fan blades and hub being broken away for the purpose of clearer illustration of the parts.

Fig. 2 is a central sectional View taken on line 22 of Fig. 1.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved alarm or signaling appara tus comprises a fan consisting, in the present instance, of a hollow drum or hub portion 1, and a'plurality of radially extending tubular fan blades or arms 2, said tubular fan blades being flattened and suitably inclined as shown most clearly in Fig. 2 of the drawings.

The improved fan is adapted to be mounted at the rear of the automobile radiator and in front of the engine cylinders in the usual manner by means of an attaching bracket 3, provided with suitable bearing members 4, the latter supporting a stub or hub driving shaft 5, said driving shaft being adapted to receive its motion through the medium of a suitable pulley 6, which may receive its motion through a suitable belting or sprocket chain (not shown) communicating with a suitable source of power.

As a suitable source of sound, a sound dia phragm 7, is provided, said diaphragm 7,

in the present instance, being of circular ordisk shape and preferably being provided on the one side with a circular series of corrugations or projections 7 which latter may be pressed out or formed integral with the diaphragm 7.

As a suitable means of mounting the diaphragm truss rods 8, are provided said rods being preferably provided with hooked heads 8*, passing through suitable openings near the outer periphery of the disk shaped diaphragm and being threaded at their outer ends for connection to and adjustment by threaded sleeve screws 9, which latter may be mounted in and supported by suitable cross bars or members 10, extending across the open ends of the flattened tubular shaped fan blades 2.

It will be observed that the tubular fan blades are adapted to act as sound conducting elements for the transmission of the sound waves from the diaphragm when the latter is thrown into motion or vibration by the mechanism hereinafter described.

As a means of vibrating the diaphragm 7 as revolved and carried by the rotating fan a pin or shaft 11, is mounted in the hub driving shaft 5, said pin being adapted to be moved longitudinally within the shaft 5, and against the resistance of a spring 12 through the medium of a suitable cord or actuating device (not shown) connected to the loop head 11, and as a means for preventing the circumferential movement of the pin or bar 11, the latter is provided with a groove 11*, adapted to receive and contain the end of a bracket 3 extending upwardly from the stationary attaching bracket 3.

r The outer end of the slidably mounted pin or shaft 11, is provided with an arm 13, extending upwardly and carrying a roller head 14, which latter is adapted to be drawn toward and to strike against the corrugations or projections 7 of the diaphragm to vibrate the latter when the pin or shaft 11, is drawn rearwardly against the resistance of the spring 12, in an obvious manner by the attached operating mechanism .hereinbefore referred to. 7

From the foregoing description, taken 1n connectlon with the accompanymg drawings,

the operation and advantages of my invention will be readily understood.
