SAMUEL C. ROD ESS, OF NEW YORK, N. Y.

SIGNAL BELL.

Application filed May 12, 1922. Serial No. 560,284.

T all whom it may concern:

Be it known that I, Samoan (l. Roo'nss, a citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Signal Bells, of which the following is a specification.

i'iy invention relates to improvements in the class of signal bells adapted to be operated to sound signals by the pressure of gases from the cylinder of an internal combustion engine, and has reference to the class of signal bells set forth in my application filed November 10, 1921, Serial No. 514,286.

One 01 the objects of my present invention is to enable the clapper'when actuated.

by pressure from an engine cyiinder to strike during its operating stroke.

My invention also comprises novel details oi? improvement that will be more fully hereinafter set forth and their pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein Figures 1 and 2 are vertical sections through a signal bell embodying my improvements, showing parts in different po'-. sitions, taken substantially on line 11 in Fig. 3;

Fig. 3 is a side view looking from the left in Fig. 1; the bell being omitted;

Fig. l is an enlarged detail face view, partly in section, or" my improved pressure controlling means;

Fig. 5 is a diagrammatic view illustrating my improvements in position on a portion ofan automobile.

Fig. 6 is aside view of a valve to control 7 pressure for the signal bell;

Figure 6 is a section on line 6 6 in Figure 6. v

Fig. 7 is a vertical section through Fig. 6; Figs.- 8 and 9 are details illustrating means to connect the signal bell with a support;

Fig. 10 is a partly sectional detail View illustrating modified means to operate the clapper Fig. 11 is. a detail view illustrating another modification to operate the clapper; Fig. 12 is vertical section of Fig. 11; Fig. 13 is a side View looking from the left in Fig. 11, the bell being omitted, and Fig. 1 1 is a section on line 14-14 in Fig. 11.

Similar. numerals of reference indicate corresponding parts in the several views:

The bell 1 is shown provided with a support 2 shown in tubular or cylindrical form. The bell may be attached to the support 2 by any suitable means, such as by the threaded piece or screw 3. Reciprocative within the bore 2 of support 2 is a movable memher 4: adapted to operate a clapper-actuator 5 that is pivotally carried upon support 2. The clapper 6 is pivotally carried within the bell upon support 2 by means of pivot or pin 7, shown extending through the clapper and lug 8 on said support, which lug extends into opening 6 in the clapper, (Figs. 1, 2, 3 and 10). The clapper is shown provided with an adjustable striker (i shown in the form of a bolt, passing through the lower end of the clapper, in Figs. 1, 2, 3, and retained in set position by a nut 6 where by the striker may be set in position on the clapper to produce the best striking results against the bell. f desired, the striker may be omitted as shown in Figs. 10 to 13. A spring 9 between the upper end of the clap per and support 2 tends normally to aid in withdrawing the clapper from the bell and to retain the clapper away from the bell as in Fig. 1, although the clapper operates also under the influence of gravity. Cooperative means are provided between the movable member a and the actuator 5 for rocking the latter according to the reciprocations of said member, for which purpose I have shown the member l provided with rack-like teeth 4* and the actuator 5 provided with teeth 5 in mesh with teeth 1 which teeth 5 extend through an opening 2 in the wall of sup port 2 to engage the teeth P. In the form shown in Figs. 1, 2 and 3, the actuator 5 has a projecting portion in cam-like form,

indicated at 5 having correspondingly curved cam-like surfaces 5 on opposite sides to operate the clapper, Fig. 2. The clapper is shown provided with an abutment 10, shown in the form of an anti-friction roll on a pin 1O in the clapper, said roll being located in opening 6 of the clapper, whereby as actuator 5 is rocked it will engage said I h hen the actuator is rocked by member 4,

abutment tin'fl'both the downward and up ward Strokes of the projection 5 to cause the clapper to strike the bell. As projection 5 will quickly pass abutment the clapper will be released from the bell for quick return therefrom, to prevent resistance to the clear ringing of the bell. In Fig. 10 the projection 5 is pivotally connected with a link 11 that is hung on pin 10 on the clap er andpivoted to projection 5 by pin 12.

the'connections or linkage 5 12; Hand 10, will cause the clapper to be quickly rocked toengage andretreat from the bell.

The bore 2 of support 2 is to besupplied gwith gasor air under pressure on one stroke rand. influenced by release of thepressure or by exhaust on the nextstroke, and so on al- Wternately, to reciprocate member 4. Said bore 2 may be connected with a cylinder of ,a' gas engine, indicated at A, by any'suit able means, either by direct connection through a holein the cylinder, or by con- .nection with a priming spark plugmounted on thecylinder, or by means of a tube 14 interposed between the cylinder and support 2; Tocontrol the effective pressure'and exthaustin bore 2 -0f support 2, I provide the following .means:the reciprocative mem- 3o lien -4 has a stem 15 depending therefrom i and which may be detachably connected to 1 member 4 by screw threads Y16 and locking nut 17: (Figs. 1,2 and 4).. The stem 15 travels freely through anapertured valve member or disk 18secured within bore 2 so that gases may passthrough the bore of 'saiddisk 18 freely around stem 15 (Figs. 1

and 2).

' stopsor shoulders 15, 15 to limit the movementof valves 19, 20,011 said stem (Fig. 4). A. spring 21 on stem 15- normally pushes valve 19 toward seat 15 and a spring 22 on said stem bearing againsta stop23 on said stem normally pushes valve toward shoul der 15 By the means'described the valves *L9and'20 may alternately bear against oppositesides of disk 18 and mayfloat with stem 15 free from disk 18 for a distance of travel of member 4.

' -A fitting 25 is provided with threads 25 fiengaging corresponding threads in bore 2? "of member 2, the inner end of member 25 i being adapted to engage yalve disk 18 to retain it against a-stop shoulder 26 in bore 2%,;(Figsu 1 and 2). The member 25 is adapted to be connected with a support and is shown provided with an external threaded 1 portion at 25, adapted to receive a nut 27;

The fitting 25 may be provided with threads ,to-receive a union fitting 28. for connection with tube 14. The threads 25 may be screwed into a support, such as the engine casing A (Fig. 8*),and nut 27 may be set against said support to retain the support 2 in the desired adjusted position. The threads 25 may be screwed into a retaining plate 29 and held in an adjusted position by nut 27, which plate 29 may be attached to any desired support, indicated at B. The construction is such, also, that the threaded part 25 of fitting 25, or the threaded part of' upp'ort 2'at 46, (Figs. 10,11, 12)",fmay be clamped by a yoke-like bracket 30 and re tained bynut 27, which bracket may be clamped on the filler neck31 of anautomobile radiator 32 (Fig. 5).

Suitab'l'emeans may be pro'vided'to control pressureandexhaust in bore 2 of support 2. In Figs. 5, 6 and 7, I have illustrated valve means comprising a"'casing 32 having a 7 union 34 5) to connect tube 14 with the valve casing. 'A valve 35 controls the flow of gas through bores 32, 32 0f casing 32 to and from tube 14. The/stem 36 of valve 35 is shown normally pushed by spring 37 to seat valve 35 and alever 38 pivoted at 39 on casing 32 is adapted to push stem 36 to unseat valve 35. Lever 38 may be operated by suitable means, such as by a wire connection 40 extending to'a lever 41 attached by a bracket 42 to the steering post 43 of the automobile, or in any other position convenient to the operator. Thecasing 32 has a threaded portion 32 and a nut a, which threaded portion may be screwed into a hole in the engine cylinder to receive fluid pressure therefrom, the nut a enabling the casing 32 to be set and retained in any convenient position for the pull-connection 40.

hen the engine is operating and valve 35 is opened the pressure and exhaust produced by the engine-will be efi'e'ctive through tube 14 to bore 2 of support2. The pressure will pass stem 15 t'hrou'gh' disk 18 and operate against member 4 to cau'seitto rise (in Fig. 1),'whereby actuator5"will rock against abutment 10 to cause clap-per 6 to strike the bell, and said actuator will pass quickly from said abutment during' the con tinued stroke of member .4 to. permit the clapper to fall away from the bell; on the 1 reverse stroke of member 4 actuator 5 will be rocked reversely to' pass abutment 10 to cause the clapper to again strike, and so on alternately, whereby rapid operation of the clapper may be effected, since the projection 5 will quickly slid-e past abutment 10 on each stroke. When member 4 has risen on the pressure stroke part of its limit of travel the valve 20 will engageseat 18 to shut off flow of 'fluidagainstmeinber'4 and the momentum of said member will cause it to continue a short distance against the resistance of spring 22 interposed under presthreaded projection 33 to'receive sure between valves 20 and 23 and then stop. F or the next stroke suction or exhaust in the lower part of bore 2 as well as the efiect of gravity, will cause member 4 to descend and its valve 20 will pass from seat 18", and toward the limit of such stroke of member 4 the valve 19 will engage seat 18 to shut oi? the effect of the exhaust in bore 2* against member 4, and. the momentum of said member will be checked by spring 21 interposed between member 4 and valve 19 and the member will stop. The efiect of the operation described is that member 4 is subjected to pressure and exhaust during a portion of its strokes'only while the remainder of its strokes is cushioned by springs 21, 22, alternately, to prevent injury to the parts by rapid reciprocations to which member 4 may be subjected.

In the forms shown in Figs. ll to 14, I provide two clappers 6 hung upon pin 7, with means to operate them alternately toward and from the bell. In this form the actuator 5 has lateral extensions or shaft portions 5, journaled in bearings in lugs 2 on casin 2, which shaft portions have eccentricalIy disposed crank pins 5 shown out of register axially with each other (Fig. 14), so as to act in the nature of doublethrow cranks. The crank pins 5 connect with links 5 that are pivotally connected with the respective clappers 6 by means of pins 5 'on the clappers (Fig. 14). The arrangement is such that as actuator 5 is rotated back and forth by the reciprocations of member 4, the crank pins 5 will be correspondingly rocked whereby the links 5 will cause alternate swinging of the clappers 6 to strike the bell alternately.

In Fig. 12 the movable member 4 is shown opposed by springs 44,45, on opposite sides of said member within bore 2 of support 2,

whereby the movements of member 4 will be restrained.

Instead of connecting support 2 to a tube 14, said support may be connected directly to the engine cylinder, as in the place of valve 32, in Fig. 5, by means of threads 46 on said support. The support may be set in the desired position for convenience in operating lever 47 and retained by nut 27. The bore 2'" of support 2 leads through the lower end of the latter and has a valve seat 48 to cooperate with the valve 49 having a stem 50, that passes through bore 2 and through a bore 4 in member 4, said stem being in position to be engaged by lever 47. A spring 51 engaging a stop or pin 52 on stem 50 and engaging also a nut-like member 53 screwed into the upper end of support 2 serves normally to seat valve 49 against seat 48. The member 53 may clamp the bell against the end of support 2, as indicated in Fig. 12.

is closed the clapper will not operate.

My improvements are particularly adapted for use as signal bells for automobiles, motor boats and the like having internal combustion engines, since when such an engine is operating and its pressure and exhaust is in bore 2 of support 2 the member 4 will be reciprocated so long as valve 35 or valve 49 is retained open. When such valve My invention is particularly useful on fire engines and ambulances, where loud ringing alarms are desirable owing to the conditions under which such vehicles are usually operated.
