REVOLVING BELL.

SPECIFICATION forming part of Letters Patent Ne. 759,003, dated May 3, 1904.

Application filed December 11, 1903. Serial No. 184,837. (No model.)

To all whom it may concern:

Be it known that I, Jonx P. hIcGA NN, a citi zen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Revolving Bells, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in revolving bells, the object of the invention being to provide a device in which a tapper is caused to rapidly and successively strike a bell to emit sounds as the bell is whirled around in the hand of the operator.

The invention relates to that class of devices employed for campaign or other jollification purposes; and one of its further objects is to construct a simple and effective device by which a sound of more musical quality than is gene ally derived from devices of this nature may be obtained.

Briefly described, the invention embraces a bell of any desirable shape, and which is provided with a pair of cars or lugs in which a handle is mounted, and on this handle is a ratchet or other form of toothed wheel adapted to engage with a springqiawl, which latter also serves as the tapper to strike the bell and cause the sound.

A practical embodiment of my invention will be hereinafter specifically described and then more particularly claimed without confining myself to the specific structure shown, and in this description reference will be had to the accompanying drawings, forming a part of this application, and wherein like numerals of reference will be employed for designating like parts throughout the different views, in which Figure 1 is a detail perspective view of a device constructed in accordance with my invention. Fig. 2 is a central vertical sectional view thereof. Fig. 3 is a transverse vertical sectional view, partly broken away. Fig. 4

is a transverse vertical sectional view of a modified form of construction.

To put my invention into practice, I provide a sounding member 1, which may be a bell of the form shown or other design of bell and which I have found in practice to be best suited for the purpose when open at both ends. It will be evident that a substantially hemispherical hell or other shape of sounding device would answer the same purpose as the particular shape shown. \Vith the form of bell shown I provide the same at its smaller end with two ears or lugs 2, between which on the stem 3 of a handle 4 is mounted a ratchet or other toothed wheel 5. This stem 3may be mounted in the lugs or ears 2 in any desirable manner, though a practi 'al construction is that herein shown, which consists in threading the stem and providing the toothed wheel with a threaded bore to receive the threaded stem, the stem having journal portions 6 7 to revolve in the apertures provided therefor in the lugs or cars 2. This is a very practical and cheap construction, and as the bell is always revolved in one direction the wheel 5 will consequently always beheld tight on the stem, and the latter will require no fastening other than the wheel to hold. the same in the lugs or ears. Securely fastened at its one end to the inner wall of the bell is a strip of spring metal bent to form a pawl 8 to be engaged by the toothed wheel 5 and then bent downwardly to form the tapper 9. By holding the handle in the hand and whirling the bell around on the stern of the handle the tapper will be caused to intermittently strike the bell and sound the same.

In Fig. 4 I show a slight modification of construction in which I aim to obtain two distinct sounds, the one by the tapper striking the bell and the other by the spring-pawl striking the wheel. The spring tapper-arm 10 may be made integral with the spring-pawl 11, as in the form of construction aforedescribed, and the spring'pawl maybe fastened to the bell direct or to a lug 12, carried by the bell, which latter may be preferred to prevent destroying the sound of the bell.

By leaving the bell open at both ends it has been found. that a clearer and less muflied sound is emitted by the device, and with either of the constructions shown it will be evident that the manner of using the device is identical.

While I have shown and described the device in detail as it has been practiced by me,

yet it will be evident that various slight changes may be made in the details of construction without departing from the general spirit of the invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A device of the type set forth comprising a sounding member having a spring-strip secured at one of its ends thereto and bent intermediate its ends to form a pawl, and means carried by the member for engaging said pawl to actuate the otherend of said metal strip into engagement with said member.

2. A device of the type set forth, comprising a hollow sounding member with a springstrip secured at one of its ends on the interior thereof, the other end of said strip being for sounding said member, said strip intermediate its ends being bent to form a pawl, and a toothed wheel carried by said member for engagement with the pawl.

3. A device of the type set forth, comprising a hollow sounding member incased on all sides and open at each end, a spring-strip secured to one side of the member interiorly, and having its other end free and adapted to engage with the opposite side of the member, and means carried by said member for actuating said strip.

at. A hollow sounding member having a spring-strip extending across its interior with one end thereof free to engage said member, and means carried by the member 'to engage said strip intermediate the ends thereof to actuate said free end of the strip.

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