Description
E. MOARD May 22, 1951 ROTARY BELL dii@ :v2/ley Patented May 22, 1951 ROTARY BELL Eric Moard, East Hampton, Conn., assignor to Bevin Bros. Mfg. Co., East Hampton, Conn., a corporation of Connecticut Application May 24, 1947, Serial No. '750,287
Claims.
This invention relates to rotary bells and more particularly to bicycle bells which are adapted to be rung by manual 'rotation of the bell member.
An object of this invention is to provide an improved rotary bell which may be readily operated with the hand and which is economical to produce and highly eicient in its operation.
A further object of the invention is to provide a bell which is adapted to operate with a two-tone sound upon the rotation of a single bell member.
Further objects and advantages of this invention will be more clearly understood from the following description and from the accompanying drawings in which:
Fig. 1 is an end view of a bell embodying my invention on line I-I of Fig. 2.
Fig. 2 is a side view, partly in central vertical section, illustrating my invention as embodied in a two-tone bell.
Fig. 3 is an end view in vertical section on line 3-3 of Fig. 2.
Fig. 4 is a side view, partly in central veti'al y section, of a bell showing a modified form of my invention.
Fig. 5 is a sectional end view thereof on line 5-5 of Fig. 4.
As illustrated in the drawings, my improved bell comprises a supporting plate 5 having rigidly mounted thereon a supporting shaft 6 which extends through said supporting plate and has an enlarged portion 1 which abuts the supporting plate. A squared section 8 fits through a square opening in the supporting plate and prevents rotation of the shaft.
An auxiliary supporting plate 9 is secured to the supporting plate 5 and spaced therefrom to provide a bearing of substantial width which receives the square portion 8 and rigidly supports the shaft 6 perpendicularly to the supporting plate 5. The said shaft may be fastened in position by swaging the edges of the squared section 8 against the outer surface of the auxiliary supporting plate 9 to thereby secure the plates 5 and 9 between the swaged portions and the shoulder provided by the enlargement 1.
As clearly illustrated in Fig. 2, a bell member I0 is threaded to the extension 6-a of the shaft 6 by means of an internal tubular hub II which rigidly secures the bell member I0 to the shaft.
A second bell member I2 is rotatably mounted upon the shaft 6 by means of an internal tubular hub I3 and is retained thereon by a snap ring I4. A cam I5, preferably having three projections I6, is rigidly secured to the hub member I3 to rotate therewith.
A hammer Il is carried on a spring arm I8 which extends from a lever I9 and rests against the stop member I8-a. The said lever I9 is pivotally mounted on a stud 20, which extends from the plate 5 into the bell member Ill, and is provided with a stud 2| which projects through a slot 22 in the supporting plate 5 to the opposite side of said plate to engage the cam I5; the said lever I9 being urged in one direction by a spring 23 to move the stud 2l into engagement with the cam.
A separate hammer 24 is carried on a spring arm 25 which extends from a lever 26 and rests against the stop member 25--a. The said lever 26 is pivctally mounted on a stud 2I which eX- tends from the supporting plate 5 into the bell member E2. rlhe said lever 25 carries a stud 28 which also engages the cam I5 and a spring '29 urges said lever in one direction to move the stud 23 into engagement with the cam.
In the embodiment of the invention illustrated, a suitable bracket 30 may be secured to the supporting plate 5 for fastening the bell to such as the handle bars of a bicycle.
In the form above described the bell member il] is preferably of a different tone than the bell member l2, and the operation of the bell is as follows:
When it is desired to ring the bell, the bell member I2 is rotated upon the shaft 6 by simply giving it a spin with the fingers. This will cause the bell to spin cn said shaft 6 and rotate the cam I5 therewith. The projections I6 of said cam will then engage with the studs 2l and 28 and cause the levers IB and 26 to oscillate on their respective studs 26 and 22, under the influence of the springs 23 and 29. This will cause the hammers I1 and 24 to vibrate and repeatedly strike their respective bell members I0 and I2 and thereby produce a double tone. It will be clearly understood that the spinning action of the bell member I2 is caused by either imparting a succession of tangential blows to the bell member with the fingers, if a continuous sound is desired, or by grasping the said bell member with the fingers and giving it a sudden twirl if a short ringing is desired. Due to the fact that the bell member I2 is of a relatively large mass, and is required to turn a cam of a small radius against the light spring tension of the springs 23 and 29, the inertia of the member I2 will cause it to rotate several revolutions between the times that the fingers have been removed therefrom and the friction of the associated parts causes the bell member to stop rotating.
As shown, the studs 2| and 28 are also disposed in such relation to the cam I6 that the levers I9 and 26 will be rocked successively to thereby permit the two bells to be struck at different times so that the two-toned effect may thereby be sounded more clearly.
In the` modiedform illustrated in. Figs. 4 and 5, my invention is embodied in a bell having a single bell member 3l which is rotatable on a shaft 32 which extends from the supporting plate S-a. In this form, a lever 33 is pivotally carried on a stud 34 which also extends from the supportingl plate -\a, and the said lever is urged in one direction by a spring 35 to retain an extension member 36 in contact with a suitable cam 3l.'
When said cam is caused to rotate by a twisting of the bell member 3i, the hammer 38 which is carried on a spring arm 39 oscillates and its motion is restricted by a stop stud il.
