HARRY BRAMMER, OF BURLEY, LEEDS, ENGLAND.

CYCLE AND LIKE BELL.

'To all whom it may concern Be it known that I, HARRY BRAMMER, of 20 Greenhow Place, Burley, Leeds, in the county of York, England, have invented new and useful Improvements in Cycle and Like Bells, of which the following is a specification.

This invention relates to improvements in cycle andlike bells. Hitherto in this class of bell the gong or dome has either been made stationary, or to rotate, and the sounding mechanism when actuated by the trigger is first moved in one direction, and when it,the trigger,-is returned to its normal posit-ion the direction of the actuating mechanism is reversed.

The object of this invention is to utilize the free wheel principle and apply it to cycle and like bells and to achieve this purpose by providing means whereby a continuous rotary motion of the disk carrying strikers is obtained, and which is not affected by the reversal of the movement of the actuating trigger.

In the drawings hereunto annexed is illustrated mechanism for achieving this object, in which- Figure 1. is, a sectional elevation of a bell provided with two gongs; Fig. 2. a plan of the same looking at the top with the upper gong removed; Fig. 3. is a part elevation of one disk striker and actuating mechanism adapted for applying the invention to bells of ordinary construction; Fig. 4. is an elevation of a pair of disks and actuating mechanism constructed in a slightly modified form; Fig. 5. is a sectional elevation of a disk and strikers with means for holding the strikers in position; Fig. 6. is a plan of same.

of internal projections which are cast therein and extend for any suitable distance. The domes a are fixed by screws 0 to the arch or bridge portion 03 of the central framework e which is in ring form and provided with the internal projections f, g, upon which a portion of the sound actuating Specification of Letters Patent.

mechanism is fixed. The arches d may be made integrally with the central frame e, or they may, as shown in the drawings, be secured thereto. Each arch is provided with a boss or bearing it into and through which the screw 0 is passed, and in the ends of the screws are formed V-shaped bearings for the central spindle i which is made to revolve freely between the arches.

On the spindle i are mounted and fixed two disks y', is at suitable distances apart. Each disk is provided with a number,say, two,strikers 1 arranged to reciprocate freely upon pins m which may either be riveted or otherwise fixed to the disks, as shown at Fig. 1, or the pins m may each be fixed to one end of a flat spring n which springs are secured at their other ends to one of the faces of the disks 7' and la, as shown at Figs. 5 and 6. The pins m pass through the strikers Z and into holes in the disks formed to receive them. The central holes in the strikers Z are made larger in size than the diameter of the pins min order that during the rotation of the disks the strikers may be thrown outward for coming in contact with the internal projections b on the gong a.

On the spindle 2' is mounted loosely between the disks a spur pinion 0 and an annular sleeve 70. On the spur pinion 0 are provided inclined projections q arranged to mesh with corresponding inclined recesses 0 formed in the upper edge of the annular sleeve 9. In the lower edge of the said annular sleeve are also formed a second set of inclined teeth 8 smaller in size than the inclined projections g and also inclined in an opposite direction. The inclined teeth 8 are arranged to mesh with the inclined teeth 1; formed on or attached to one of the surfaces of a boss 7 which may either form part of Ellie disk is or be separately fixed to the spin- The spur pinion o is made to engage with a spur wheel M which is narrower in width than the spur pinion 0. Fixed to the spur wheel 26 is a second spur pinion a with which the tooth segment to and the trigger or operating device m,-provided with the enlarged thumb piece y,is made to mesh. The spur wheel u and pinion 'v are mounted upon pin a which is fixed to the internal projection f and the operating lever :12 is pivoted to a pin 1 which is carired by the internal projection g.

In the modified form of apparatus shown at Fig. 4. two spur pinions 0 and 2 are mounted and fixed upon the central spindle 2' between the disks and the said spur wheels are made to gear with two separate spur wheels u and 3 of narrower width mounted upon a long spindle 1 which is employed in place of the one marked 2, shown at Fig. l, and in this case a spur wheel 5 takes the place of the spur pinion o, and the spur wheel is provided with the inclined teeth 9, and the spur wheel a with the inclined projections t, and the annular sleeve 77 is then mounted upon the pin 4 instead of upon the central spindle 2'. In this instance the tooth segment 10 of the trigger on is made to gear with the spur wheel 5. In all other respects the apparatus is the same as that described for Figs. 1 and 2.

At Fig. 3. is shown a method for applying this invent-ion to the existing type of bell where only one disk 7' is employed, then a tube 6 is fixed to the disk by any suitable means and the boss 7 provided with the inclined teeth t on its upper edge is then made separate from the disk is shown at Fig. 1. In this case the spur pinion 0, and the annular sleeve p are mounted loosely upon the sleeve 6, and the boss 7 is fixed upon the sleeve 6. In all other respects the apparatus is the same as that shown at Fig. 1.

' The action of the mechanism shown at Figs. 1 and 2 is as follows :The trigger m by means of its tooth segment to actuates the spur pinion o and motion is transmit-ted through wheel u to spur wheel 0, on the underside of which are the inclined teeth or projections 1'. As the wheel 0 rotates by the inclined teeth coming in contact with the inclines on the upper edge of the sleeve 79 the wheel 0 is moved up the central spindle i and jams or wedges the annular sleeve by moving it downward so that the inclined teeth 8 and 25 come in contact with the boss 7 thereby imparting a rotary motion to the central spindle 2' and disks j and mounted thereon which causes the said disks to rotate in the same direction as the central spindle 2' when the trigger a; is returned to its normal position and therefore moved in an opposite direction by pinion 0 and annular sleeve 79 being mounted loosely upon the central spindle As the act-ion of the trigger is reversed the inclines on the upper portion of the annular sleeve and the inclined projections will then be allowed to return to their normal position, and in so doing the smaller teeth 8 at the bottom of the sleeve 79 will be enabled to ride over the teeth 25 and thus permit of the disks continuing to revolve in their original direction independently of the movement of the trigger w and tooth segment to. As the disks j and 7c revolve the strikers Z are thrown outward and come in contact with the projections 6 whereby the the action is thus the same as that already described.

For Fig. 3. the same action is employed as at Fig. 1; the spur wheel 0 gearing with spur wheel and pinions marked respectively u and o and operated as described by the trigger and its tooth segment.

What I claim is 1. The combination of a pair of stationary gongs having internal projections, with framework arranged partly within and partly without the gongs to which the latter are attached, said framework comprising a central ring having arches projecting beyond opposite sides thereof and provided with internal projections at right angles to its main portion for supporting portions of the actuating mechanism.
