SPECIFICATION forming part of Letters Patent No. 547,886, dated October 15, 1895.

Application filed August 8, 1895. Sen'al No. 558,604. (No model-l Patented in England November 15, 1894, No. 22,049.

T at whom it may concern:

Be it known that I, ALFRED NICHOLAS, manufacturer, a subject of the Queen of Great Britain, residing on Water Street, in the city of Birmingham, England, have invented new and useful Improvements in Bells, of which the following is a specification, and for which said invention I have obtained Letters Patent of Great Britain, dated November 15, 1894, No. 22,049.

My invention has relation to repeater-action bell mechanism comprehending a repeatingstriker and means for communicating motion thereto;

Figure 1 of the accompanying drawings represents, partly in vertical section and partly in elevation, a cycle-bell provided With'a repeating-striker and striker-operating mechanism constructed according to my invention. Flg. 2 represents a horizontal section of the bell upon the dotted lines 0c 00, Fig. 1, thus showing the inter-gearing driven and driving elements of the mechanism and the revoluble striker, whose ends are alternately made to strike and re'cede inward on each rotation of the casing, within which it is carried and wherein it stiffly slides. complete vertical section of the bell. Fig. 4 represents a similar view as Fig. 3, but with the section taken at right angles upon the dotted line A of the said Fig. 3. Fig. 5 represents an elevation and top, side, and underneath plans of the striker-casing and its driving pinion. Fig. 6 is a part section and a plan of the bolt-like striker separately. Fig. 7 represents the arbor or upright spindle upon which the carrying-casing of the strikerrotates; Fig. 8 is a section of a different arrangement of the striker. Fig. 9 is a top plan view of the same. Fig. 10 is a plan view of another different arrangement of striker.

The same letters of reference indicate corresponding parts in the several figures of the drawings.

Located within the interior of the hell on is a reciprocating plunger-like striker I), carried by and working to and fro within a revoluble carrier or casing 0, having made fast to its under side a pinion (1, through which pinion and the center ofthe casing and through a stop- Fig. 3 represents a hole I) in the striker an arbor or spindle e, carried by the base-plate j, upwardly passes and upon which the pinion and casing revolve when the said pinion is driven by its teeth engaging with those of a double-toothed sectorf or a toothed sector having upon the opposite part of the central stem or pillar g is a coiled spring h, with one end 72. made fast to the pillar and the other end h taking around a stud f on the toothed sectorf, so that as the said combined sector and half-pinion is partly rotated through the teeth 2" of a toothed leversector turning about the pivot-pin i secured to the said base-platej as a center, the coils of the spring are wound up or compressed, and its reaction automatically takes the strikeroperating mechanism back to its normal position. The toothed sector there a thumb lever or arm 4' extending through a gap 7" in the base-plate. Thus by pressing the said thumblever in'the direction of the arrow, Fig. 2, the toothed sector 11 turns the toothed sector f through the medium of the half-pinion f, whereby the pinion d is rapidly rotated and with it the revoluble striker casing or carrier 0, which in itsturn carries with it the plungerlike striker b, and, beinglonger than the casing, one or other of its ends is always projecting to a distance beyond one or other of the casing ends, thereby coming within the range of the inside of the bell, so that as the projecting end is rapidly brought round and against the inside of the bell it strikes and rings the same, and is by the impact impelled driven or shot back through the casing, causing the other end in its turn to extend alike unto the first-named end or to be ready to again strike the bell when the said last named end is brought round to its acting position. This is repeated continuously and two rings of the bell are made by every single rotation of the striker.

The hollow pillar or stem 9, which is car ried by the bell base-platej, has fitted within its upper part a rotating screw-box it with a milled head 10 on its upper end and with the inside stem part receiving a like screwed stalk m, having at its lower end a hook m over which the pierced and loose end a of a band-clip at, having its after end a made fast to the base-platej, passes. The band-clip is drawn tightly around the member to which the bell is attached by turning the milled head which draws the screwed stalk m and with it the free end of the clip up to the stem 9; hence the connection.

Fig. 8 represents a section of a modification of the striker part of my improvements, and Fig. 9 is a top side plan of the same. In this form the striker 1) works within an opentopped casing 0 instead of a closed one and is made to move stiltly by a spring 13, located round the central stem 6, carried by the baseplatej and between the head e and awasher 6 coming upon the top side of the striker. a is the bell, d the pinion, andfthe driving-sector of it.

Fig. 10 represents a further modification of the striker part of my improvements. In this arrangement the striker, which is now flat, is the same in principle as the one already described, but the plungers are in duplicate, so that to each rotation of the carrier four rings are given instead of two. a is the bell. Z) Zfiare the reciprocating strikers. c is the easing or carrier; cl, the pinion; e,the stem, passingthrough an axial hole in carrier and pinion, and through slots or stop'holes in the strikers. The stem has a coiled spring located around it and coming between the head thereof and a washer located upon the top side of the upper striker Z), which has a sinking about its middle for the lower striker to Work and be guided within. fis the sector driving the pinion d, and j is the base-plate carrying the stem 6. \Vhen the double striker is rotated, the ends are continuously driven in, as they impinge against the inside of the bell; hence four strikes and rings to each single rotation.

Having fully described myinvention, what I desire to claim and secure by Letters Patent is- 1. In the strikers of repeater-action bell mechanism, the combination with arevoluble carrier driven by a pinion made fast with it and turning upon a central axis, of a reciprocatin g double-ended striker, whose ends are alternately brought into and taken out of a striking position by being impelled rearward by impact on striking and ringing, substantially as described and set forth.

2. In the strikers of repeater-action bell mechanism, the combination with a revoluble carrier driven by a pinion made fast with it and turning upon a central axis, of a pair of reciprocating double ended strikers whose ends are alternately brought into and taken out of a striking position by being impelled rearward by impact on striking and ringing, and a spring for stiffening the movement of said striker, substantially as described.

3. In the motion-transmitting mechanism for bells, the combination with a toothed leversector pivoted to the base plate, of a plate having two toothed sectors revoluble about a central stem and with the teeth of thelarger sector meshing with the teeth of the striker pinion and with the teeth of the smaller sector meshing with the teeth of the said lever and driving sector, substantially as described and set forth.

4. In the motion-transmitting mechanism for bells, the combination with a lever sector turning about a pivot carried by the base plate, and meshing with the teeth of one part of a double sector plate, the teeth of whose other part engage with a striker pinion, of a coiled spring, whose ends engage with afixed part of the bell and the double sector plate, respectively, substantially as and for the purpose described and set forth.

5. In the repeater-action mechanism of bells, the combination with a lever sector turning about a pivot carried by the base plate and meshing with theteeth of one part of a double sector plate, the teeth of whose other part engage with the striker pinion, and a coiled spring having one end secured to a fixed part of the bell and the other secured to the double sector plate, of a reciprocating double-ended striker bolt carried by a revoluble carrier and whose ends are alternately brought into and out of astriking position by striking the bell, substantially as described and set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALFRED NICHOLAS.
