CONTROLLING DEVICE FOR LOCOMOTIVE 0R ENGINE BE LLS Filed Nov. 5, 1930 Maui/V702, Gay/1.45 8. Pras1 Patented May 19, 1931 ORVILLE ."BOYER PETERS, OF WINNIPEG, MANITOBA, CANADA CONTROLLING DEVICE FOR LOCOMOTIVE R ENGINE BELLS Application filed November 5, 1930, Serial No. 493,595, and in Canada September 16, 1930.

This invention relates to controlling device for locomotive or engine bells and an object of the invention is to provide a device whereby a bell of this character maybe prevented from revolving? ,and caused to swing 111 any given are.

A further object of the invention is to provide a device of this character which will correctly arrest the motion of the bell at a fixed point to prevent it from overturning, without interference with the bell ringer, bell rope or the bell.

A further object of the invention is to provide a device of this character which will allow of a wide range of adjustment of the valve opening in the bell ringer and which will ensure the safe and successful operation of the bell ringer in starting and at all times.

A further object of the invention is to provide a device of this character which will tend to lengthen the life of the bell and bell mechanism and which will reduce the cost of maintenance thereof.

A still further. object is to provide a mechanism of this characterlwhich will increase the value of the bell as a warning signal in eifecting more prompt, more effective andbetter regulated operation of the bell.

With these and other objects in view the invention consists essentially of a controlling member mounted upon one of the bell trunnions, part of the controlling member being relatively movable to another part thereof and adapted to contact with a suitable stop or the supporting structure of the bell when it-has turned to a predetermined position thereby arresting the movement of the bell, as more fully described in thepresent specification and illustrated in the accompanying drawings which form part of the same.

In the drawings, 7

Figure 1 is a side elevation of a locomotive bell on its mounting and fitted with the controlling device also shown in elevation.

Figure 2 is an end elevation of the bell on its mounting structure, showing the j mounting attachment also in end elevation.

Figure 3 is a perspective view of one part of the control member in the or yoke.

Figure 4 is an end elevation of another part of the control member, preferably in the form of an oval collar.

Referring more particularly to the drawings, A indicates the bell support and B indicates the bell oscillatably mounted on the support by means of a cross-arm G provided with trunnions 10 and 11. The trunnion 11. is of greater length than the trunion 10 so that it projects beyond the support in the extension 12.

Upon the extension 12 a centre piece or collar 13 is mounted which is oval or substantially oval shape to obtain most effective results. This collar is rigidly secured to the trunnion extension by means of a taper pin 14 so that upon oscillatory movement of the trunnion arm and extension 12 the collar or centre piece 13 will correspondingly move. This collar is made subform of a clip stantially in the form of a drum being provided with peripheral flanges 15 so as to provide a channel 16 therebetween which is based by the drum surface 17 of the collar.

(lo-operating with the drum surface of the collar are the inner surfaces of the control member, namely the clips or yokes 18 and 1 19. The clip or yoke 18 is designed to bear upon the lower drum surface 17 between the flanges 15 and to this end the centre portion of the yoke is bent to form the semi-circular depressed portion 20. The outer ends of this yoke are bent to form the semi-circular downwardly turned projections 21 which extend beyond the ends 22 of the corresponding clip or yoke 19, as will be clearly illustrated in Figure 1.

The co-operating clip or yoke 19 is formed similarly to the yoke 18 with the bent semicircular portion 23 which is adapted to bear upon the upper drum surface 17 between the flanges 15 in the channel 16 so that the yokes 18 and 19 practically embrace the whole of the drum surface 17 when mounted in normal operating position.

Orifices 24 are provided in the intermediate portions of the yoke 18 which register with corresponding orifices formed in the preferably of ends 22 of the yoke or clip 19 when they are mounted on the collar 13 and through these tween the ends 22 of the yoke 19 a-nd the cross-head 2 6i which' ipresses' clip! or yoke 19 againstthe 'dru'm' surface 17 of the collar- 13 and similarly through the upward pressure" of the springs on the cross-headdraws the yoke 18 in bearing engagement with the drum surface 17 through them'eclium of the retaining nuts 28. i

The springs '27 'may' beof any suitable character and may be simple :orcompound dependingup'on the relativeweight of the bell and the power ofthe bell ringenforin- V stancea combination of light and heavy springs of unequallength may be'advantageously used, Anyalteration in the form of the sorings,'howe rer. vmay be made to meet- V k 1 support through trunnlons comprislng a conj with" required conditions. 1

lnoper'at onjwhen the bell is" oscillated a will swing untilone end 21 ofth'e clip or yoke 18comes iii-contact with the bell-sup? v injure parts but in amanner-as totake up porting'structure (see Figure 1 as at 29), or any other suitable stop may be provided for this purpose. When-contact otthis, charac tertakes place the swinging movement of the yokefl8'ceases and'anyffurther movement of the bell is automatically retarded by the action of the drum surface17 of the collar, 13

inturning andexp'anding 'the clips or y'okes 18 'an'd19 aga1nst thespr1ngtens1on set up by thecoil springs 27 in conjunction with the cross-'head'26 and "bolts 25. The swing- 1n'g movement of the bell is-therefore arrestedin a manner which will'not cause a sharp stop ofthe 'belland'therebytend to any sh'ock upon checking the'bell motion;

Due-t0 the fact'that'the collar 13 and consequently the drum surface 17 thereof is oval in shape, the action of this member upon the yokes18fand 19 is such as to tend to spread them apart to an increased eXtentthe farther the bell swings] This correspondingly increases the tension of the coil "springs 27 and increases the inaterialfriction' between the yokes and the drum surface of the collar 13' so that an'atural increased braking, ac-

tionor resistance to motion is the result.
