WARNING-SIGNAL FOR-AUTOMOBILES AND THE LIKE.

Specification of Itetters Patent.

Patented Feb. 22, 1916.

Application filed September 5, 1913. Serial No. 788,334.

York and Stateof New York, have inventednew and useful Improvements inWarmng- Signals for Automobiles and the like, of which the following is a specification.

This invention relates to a horn, or signaling apparatus adaptedfor use on automobiles, boats and oth'erdevices of that type which is manually operated, in contradistinction to motor operated devices of this class; and the primary object of the invention is to provide simple and effective means whereby a rotary motion imparted to a prime actuating device by a direct manual pull or actuation will be transmitted to a diaphragm with increased operating efliciency and advantage from a standpoint of momentum and set up a strong and practical vibration of the diaphragm to produce a warning tone or signal.

A further object of the invention is to provide hand-actuated means for setting up a Vibration of a diaphragm through the medium of a toothed wheel or analogous device cooperating with the diaphragm at an increased rate of speed relatively to the primary impulse imparted to the device through manual operation and also to cause said toothed wheel to have a bodily whirling movement while rotating to effectively engage a portion of the diaphragm with an advantageous vibrating impact.

With'these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed. a

In the drawing: Figure 1 is a longitudinal vertical section of a greater portion of a warning or signaling device embodying thev features of the invention. Fig. 2 is a transverse vertical section taken in the plane of the line 2 2, Fig. 1, and looking in the direction of the arrow. Fig.3 is a transverse vertical section taken in the plane of the line 33, Fig. 1, also looking in the direc-- tion of the arrow. Fig. 4 is a transverse ver tical section taken in the plane of the line 4-4:, Fig. 1, looking in the direction of the arrow.

The numeral 5 designates a suitable inclosing casing having an interior supporting frame or brace device 6 and a rear center bearing 7. A resonator 8 is suitably attached to the front extremity of the casing 5 against a. diaphragm 9 having the usual center projection 10 extending rearwardly therefrom. The diaphragm 9 is held at its periphery between a securing flange 11 of the resonator and a flange 12 of an annular gear13. .The'interior frame or brace 6 has a center bearing enlargement ll with sockets ment 14 a shaft 17 is rotatably mounted and provided with antifrictional ball and cone devices 18 and 19 fitting in the sockets 15 and 16 ,to provide a free operation or antifrictional movement of the shaft 17. The front counter-balancing disk 20 from which two arms 21 and 22 forwardly project, the arm 21 having an upright sleeve 23 at its 'forward extremity and the arm 22 having a bearing socket 24 at its forward extremity below and in line with the said sleeve; and 111 the sleeve 23 and socket 24 a counter-shaft 25 is rotatably mounted. The counter-shaft 25 has a pinion 26 secured on its upper end and held in continual mesh with the teeth of the gear 13, and also'fixed on the said shaft between the sleeve 23. and socket 2 is a toothed wheel or diaphragm vibrating means 27 which is held in continual engagement with the projection 10 of the diaphragm; The rear extremity of the shaft has a ratchet wheel 28 mounted thereon and is engaged by a part of the prime operating mechanism manually actuated as will now be described. 7

In the bearing 7 one end of a stub shaft 29 is screwed or otherwise secured in alinement with the rear end of the shaft 17, and thereonv is fixed a barrel or arbor 30, see

.Fig. 4, to which the inner end of a spring pull-strap or band 31 is made fast and coiled therearound. The barrel or arbor is a part of adrum 32 and both are loose on the shaft, The free extremity of the band or strap 31 1s passed through a slot 33 in the casing 5 and is provided with a terminal grippin dewith the hand and drawn outwardly, preferably by a quick motion, and by this means the drum 32 is rotated. and through the pawl or dog 35 engaging the ratchet wheel 28 the shaft 17 and all the parts carried thereby are likewise rotated. Theshaftl? is given considerable momentum by the fiy-wheel or counter-balance disk '20, the latter having weight that may be varied as desired. The rotation of the shaft 17 and fiy-Wheel 20 with the arms 21 and 22 carrying the shaft 25, pinion 26 and toothed wheel or diaphragm vibrating, means 27, causes the said shaft 25 to bodily rotate around the outer extremity of the shaft 17 and gives a rapid rotation to the wheel or diaphragm vibrating means 27 through the engagement of the pinion 26 with the annular fixed gear 13 on its axis. Hence, the toothed wheel or diaphragm vibrating means 27 is both bodily rotated and axially rotated, and as a consequence the teeth thereof strike the projection 10 in varying angular positions and set up a strong vibration. of the diaphragm and produce a loud and prolonged warning tone or signal. A single pull or operation of the strap or band 31 will cause the mechanism to effectually operate, but repeated pulls thereof in succession, after release to allow the strap or band to return to normal position, will give a stronger and longer warning signal or sound. After the strap or band 31 is released it automatically coils itself in the drum 32 on the barrel or arbor 30 and is thereby always in position for operation. Though the spring strap or band 31 and the drum 32 are preferred as the prime operating or motive means, the remaining mechanism is not limited in its operation to said mechanism, and it is pro-- posed to use an T other prime motor mech anism adapted or the purpose. The improved Warning signal is economical in its operation, and the several parts are of a strong and durable character. The association of the parts is such that they will not become displaced and the device as a whole is consequently rendered sure in its operation.

In'my copending application Serial No. 832,313, allowed December 22, 1914, I have incorporated the broader claims covering corresponding subject-matter in the present application and as hereinbefore described and shown in the accompanying drawings.
