AUDIBLE ALARM FOR MOTOR-VEHICLES.

To all whom it may concern Be it known that I, WILLIAM SUMNER, a subject of the King of Great Britain, and a resident of Liverpool, England, have invented certain new and useful Improvements in Audible Alarms for Motor Vehicles, of which the following is a specification.

This invention relates to an improved means for operating an alarm of the bell or gong type from a rotary part of the engine of a motor car, preferably the cooling fan of the radiator.

According to this invention a bell, gong, or analogous device is adapted to be moved into the path of a series of hammers or the like abutments on the blades of the radiator cooling fan, or other analogous rotary or moving part of the engine. Means such as a Bowden wire or other articulation being provided, connecting the bell or gong to a suitable operating means on the dash board of the car, whereby the gong may be moved to a greater or less extent into the path of the hammers, and the intensity of sound emitted by the alarm varied accordingly.

The invention is illustrated in the accompanying drawings, in which,

Figure 1.-is an end view of an alarm mechanism in accordance with this invention, Fig. 2. being a side View of Fig. 1., and Fig. 3. a detail in section of the operating mechanism.

In carrying out the invention a series of hammers 1, either spring controlled or preferably, as shown loosely fitted in angle brack' ets 2, are secured to the blades 3 of the usual cooling fan mounted behind the radiator 4. As the fan is rotated by the belt drive 5, the hammers 1 although loosely mounted in the brackets 2 assume, under the centrifugal ac tion of the rotating fan, a somewhat rigid outstanding position. A bell, gong, or the like 6, is bolted at 6 to an arm 7 pivoted at 8 to a bracket 9 secured to the radiator 4 by bolts 9 or other suitable part of the car. To the arm 7 and the bracket 9 is connected a tension spring 10 tending to draw the gong 10 into the path of the hammers 1 as the fan rotates. An adjustable stop 11 is provided whereby the inward movement of the bell Specification of Letters Patent.

under the action of the spring may be limlted. The gong 6 or the pivoted arm 7 is connected by, say, a Bowden wire 12 or other artlculation to a sliding plunger 13, mounted on the dashboard of therar. This plunger 13 slldes in a tubular guide 14, and is normally pressed outward in its guide by a sprlng 15 and the bell 6 consequently held, by the action of such spring tensioning the wire 12, normally clear of the path of the rotating hammers 1. By pushing the plunger 13 the spring 14 is compressed, and the hell 6 permitted to be drawn into the path of the hammers 1 by its own spring control 10. According as the plunger 13 is depressed to a greater or less extent so will the bell be moved more or less into the path of the hammers, and the intensity of the alarm may be thus graduated. The position of the bracket 9 may be above the gong or below it, as indi cated by the dotted lines Fig. 2., and a thick ened part 16 provided on the rim of the gong at the point which is struck by the hammers.

I claim 1. In a motor car alarm mechanism, in combination; a fan, a series of hammers fitted to the blades of the fan, a gong mounted in proximity to the hammers, a spring tending to move the gong into the path of the hammers, and means controlled by a push or the like for holding the gong out of the hammer path.

2. In a motor car alarm mechanism, in combination, a fan, a series of hammers fitted to the blades of the fan, a gong carried upon a pivoted support in proximity to the hammers, a spring tending to move the gong into the path of the hammers, a spring holding the gong normally out of the path of the hammers, and a push articulated to the pivoted gong support.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM SUMNER.
