BELL v Filed April 7, 1945 Patented Mar. 11, 1947 ,i
UNITED- STATES f PAT-'ENT OFFICE BELL- l Alfran; ElergNew. York, N; y., Application Aprila', 1945, s'rialzNassnrm-y This -invention relates to improvements in bells and, more Vspeciiically, to' La newand irri-g proved rotary bell which'gis well adapted 4for Various purposes-such` as-,burglar alarms, bicycle bells, store bells andthe" like.
The term rotary bell usually definesa bel which isactuated by rotation of a handle' or a wheel,V or the like, asdistinguished from bells that. are actuated by a reciprocating motion vof a handle, of a push button, or the'like. Thefuse ofr rotary bells has; been limited due-to the fact that the. hitherto kn'ownbells. of thistype' pro,- duceasound only when their rotating parts are turned at a comparativelyhighspee'd, and due to the factthatthe hitherto. known rotary bells are. complicatedfexpensive and. more-'subjected to wear and tear thannother.v typesv of bells, Therefore; the primary' object of` the present invention is theprovision of a device'of the-:character described."which=reliably= will produce a clear sound irrespective of the.` speed by which it is actuated, and which particularly willlproduce'the soundf even-if itisiactuated at aslcwmotion speed. y A
Another object of' the presentr invention is the provision of a device. of the character described which canbe installedv easily on.- windows, doors,` drawers. of cash registers,v and, the like, and which will. produce the desired. sound if it is turned.v ina clockwise aswell as in. an anti-clockwise direction.
Still another object ofthe present invention is the provision of .-a device ofthe-'character described which is closed all aroundinsueh a mannerv that it will permit practically no. access of dust, humidity and the# like toits mechanism.
Yet still another object of the present invention is the provision: of a device' of the character described: which .is 'simpleA in construction and inexpensive to manufacture, but reliable inoperation and well vadapted to withstand the rough usage to which ,suchj devices are-ordinarily sub-1 jected. 'q
Furtherrobjectsl of theinstant invention reside in.' anypnovel combination` of parts present in the embodiment of. the1 invention described and shown in .the accompanying: drawing Whether within or .without the .scope of'. .the appended claims and..irrespectivev of other specific statementsvas to the scope ofthe invention` contained herein.
In. the drawing:

it -is-used'asa burglar alarmin connection with al slidingwndgw; i v K f Figure 2 is` a top.-.plan View ofthe device asit appears -aiter the` removal vof the bell cup;v
Figure 3 is a sectionalv view on the..line.3-3 of Fig; 2; and
Figure4 isa top plan view ofv thedeviceasit appears after the=rernovallof the bell c1.lp,1sl1ow,` ing a slight modification of adetaih f Similar.` numerals refer to.V similar parts throughout the several views.
In Figs; 1 to V3` the numeral-I vdenotesmy. im. proved rotating bell, which Vmay be held inplace by any'suitable means,=andf.which inthe instance shown in Fig. l is attached'to thestationary part ofaiwindowframe 4 by means oi angular'mem-jl silient member, preferably byY a vflat-stprinfg'a-fr, 'which' isa-ttached to'l part 2V by means' of `rivets or the like that are .extended-'throughholes 6 in spring 5. The -spring -5= pressesthe device I against the movablewindowpart-'I in. suclr'a mannerthat the rotatable disk ywhose-rim rests against the part l, will be rotated if the Window isslid-up` or down; I prefer 'to providethe. outer side of the rim of disk 8 with a roughagef; so that even a slightpressure of `spring 5 Will. be suicient for rotating the.Y disk 8 when the window isopened or'closed. The parts 4 and 'IlV of the window are shownl as :being: partially broken away in Figrl.
The disk .81 is rotatably carried by a shaft I2 and is located betweeny thevertical` portion II of a bearing bracket and a cross-barr I3 which is non-rotatably secured to shaft I2; The horizon.- tal portion I0 of, thebearing bracket is secured to the spring 5, and the shaft I2 is stationary and is securedto the. vertical `portion vI I. A circular row of pins I4 extends Aperpendicularly from one.v side of disk 8,. and;v the. pins;I4v are in spaced: relation vtoene another,as may beA seen in Figs; 2A and 3; -W-hilethe pins` Ilican beattached to the disk 8 -in any suitable manner, 'I prefer to` form theml asaunit with disk- 8.- or to stamp them out of disk 8 and bend them rectangularly to the surface ofthe disk'8so thatthere will be slots I5' in disk B .as shown in Figs, 2 and 4. The pins I4 are arranged in such; a 4manner that they engage-tiltable'members which are-pointed tongues I'i'and ITin'the:instanceshown in Figs. 2 and 3. The-tongue I5 is pivotally attached to theportion I9 of af curvedarm, andthe'tongue I'I'ispivotally attachedto portion 20 of another curved arm; i One of these arms isfpivoted A.to each v.extremity o fthestationary cross-bar I3 at 23, andrpins I8 are arranged near the tongues I6 and I1 respectively for the purpose of limiting the tilting movement of the tongues I6 and I1. Springs 2l and 22 are provided on the arm portions I9 and 20 respectively and engage the crossbar I3 in such a manner that they bias the portions I 9 and 20 toward the pins I 4. From the arrangement'of the parts I4 to 23 just described it will be obvious that, upon rotation of the disk 8 in either direction, the tongues I6 and I1 in cooperation with the pins I4 and I8 and the springs 2I and 22 will cause an oscillating tiltingt movement of the arms, so that the hammers 26, which are on the arm portions 25, will strikeY against a bell cup 21 each time when the springs 2I and 22 swing the arms around the pivots 23 in a clockwise direction. In Fig. 2 the arm portion 20 is shown in a position in which the hammer 26 strikes or just has struck, while the arm portion I9 is in a position just before the striking of the hammer. The bell cup 21 is carried pref-` erably by the outer extremity of the stationary shaft I2 (Fig. 3), and its lower periphery is surrounded Vby the rim of disk 8,so that there will be but a small open space between the edge of the cup 21 and the disk 8. This will, to a considerable extent, protect the clock mechanism against dust, humidity and the like,` because the parts I3 to 26 inclusive are substantially enclosed and protected by the cup 21 and the disk 8. That portion of the stationary cross-bar'I3 which is adjacent the disks is provided with recesses 28 (Fig. 3) through which the pins I4 travel when the disk 8 is rotated. T The arm portions 25 are recessed at 24 (Fig, 2) in such a manner that the recessed portions 24 will rest against the cross-bar I3 when the springs' 2I or 22 swing the arm portions 25 outwardly and when the cup 21 is removed, so that the tilting movement of the arms is limited and that a hitting of the portions I9 and 20 upon the pins I4 will be prevented.
The purpose of the tiltable tongues I6 and I1 is to assurerarproper hitting movement of the hammers and a sounding of the bell irrespective Vof the speed by and the direction in, which the disk 8 is rotated. Y
According to the modification of Fig. 4, onl the tiltable two prongs fork 30 is substituted for the pointed tongues I6 and I1. The fork-30 is pivoted to the arm at 3|, and its movement relative to the arm is limited at one` side by a pin 33 and at the other side by a pin 32. The pins 32 and 33 aresecured to the arm, and pin 32 can be utilized as support for the'spring 22. The arm portion 35 and the hammer 36 are identical to the portion 25 and to hammer 26 respectively of Figs. 2 land 3. Although I have illustrated my invention in the particular form shown in the drawing, it is to be understood that I contemplate constructing it in various ways and therefore I do not desire to be limited't'o the exact structure as shown but aim to cover all that which comes within the spirit and scope of the 'appendedv claims. Y y
