NORMAN T. MILLS, OF EVERETT, MASSACHUSETTS.

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent N 0. 576,137, dated February 2, 1897.

Application filed March 28, 1896.

To all whom itmay concern:

Be it known that I, NORMAN T. MILLS, of

ment in Bells, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates particularly to bicycle-bells, and has for its object the production of improved striking and actuating mechanism therefor, means being provided for holding or looking the movable parts of the bell from rattling or jumping abou t when not in use.

The various novel features embodied in my invention will be hereinafter fully described in the specification andparticularly pointed out in the claims.

Figure 1 is a top or plan view of a bell embodyin g my invention with the gong in place. Fig. 2 is a similar view, the gong being removed. Fig. 3 is a plan view of the base with the hammer-carrier and one of the gears omitted to more clearly show the locking means. Fig. 4 is a diametrical section of the bell with the gong in place, taken on the line at 00, Fig. 2. Fig. 5 is an enlarged detail view in elevation of the movable parts of the bell, one of the rier being shown in section. Fig. 6 is a side elevation of the bell, and Fig. 7 is a detached plan view of the locking device.

The base a, struck up or stamped from suitable sheet metal and having upon its unis secured in'place, has mounted thereon a post a, threaded at its upper end at a to enter a threaded hub g of a gong g of suitable construction, provided on its interior with one or more lugs g to be struck by the hammer. A bearing-plate a is secured to the base interiorly by two studs a a diametrically located at opposite sides of the post a, and upon the stud a is mounted the extended hub b of the actuator, (shown as a lever b, extended at one end through a slot 5 in the wall of the base and provided with a handle or finger-piece b The inner end of the lever is bent to form an interiorly-toothed segment 12 the teeth of which engage a pinion c, forming a part of the hub of a large gear 0, mounted to rotate on the central post Serial No. 585,200. (No model.)

a This gear a engages the teeth of a long pinion d, rotatably mounted on the stud a said pinion having secured to its upper end a gear cl, which in turn engages a pinion e,- also rotatable on the post a above and resting on the hub of the gear 0.

As best seen in Fig. 5, the hub of gear a is upwardly and inwardly beveled, as at 0 and the hub of the pinion e is inwardly and down- .wardly beveled at e for a purpose to be described.

A locking-plate Z (shown separately in Fig. '7) has holesZ Z to receive loosely the pinion d and the beveled portions c e respectively, for a purpose to be described, the lockingplate normally affording but little resistance to the rotation of the parts specified when the bell is rung, said plate resting lightly on the pinion c and the curved end of the lever 12.

The hub of pinion e is upwardly extended (see Fig. 4) and receives tightly thereon a washer to and the hammer-carrier h, to be described, the carrier being shown as an elongated plate or bar having holes therein near its ends, as at 71., one of such holes being shown at the right, Fig. 5. A stud it, having a large head It at its lower end, is extended up through each hole and loosely through a substantially triangular block of metal h forming the hammer, the base or inner side of the hammer near the stud being preferto the hub of the pinione above the hammercarrier, the end of the spring being secured to the car, as clearly shown in Fig. 5.

The wall pf the base a is struck up, Figs. 2 and 3, into a loop a to hold one end of the spring 8X, which moves the lever bin one direction, the other end of the spring being attached to a lug b on the lever, the loop a being much easier and cheaper to make than a stud or pin secured to the base. A second lug b on the lever 11 is so located thereon that when said lever is in normalinoperative position, Figs. 2 and 3, the lug will bear firmly against the edge of the locking-plate Z, crowding it against the pinion d and also against the beveled portions e e of the pinions c and e. The plate thus looks or acts as a brake upon the three pinions, holding them from vibration or partial rotation so long as the spring 8X draws the actuator or lever 11 against the plate Z, which may be of metal or of fibrousmaterial, as desired.

By making the hammer ZLX substantially triangular and pivotally mounted near its inner side or base the said hammer will turn easily as it passes the projection g on the gong, obviating the pushing in of the hammer radially to pass the projection, and thereby effecting an easier operation of the bell.

The spring 3 s acts to control the movem ent on the hammer-carrier h, and also serves to maintain the hammer yieldingly seated thereupon, and the part .9 of the spring acting upon the convexed base kg to normally position the hammer, as shown in Figs. 2 and 5., ready to strike the gong project-ion when the. hammer-carrier 7t is rotated.

The movement of the stud 7c inthe enlarged hole h of the carrier also provides for quite a range of movement of the hammer.

A detailed description of the operation of the actuating mechanism will not be necessary, as the same will be obvious from the specification and an inspection of the drawings.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a bell of the class described, a central post, a hammer-carrier rotatable thereon and having an attached pinion; a locking-plate to at times engage and hold the pinion; a vibratable actuator having a segmental gear, and gearing intermediate it and the pinion, the actuator on returning to normal position engaging and moving the locking-plate into operative position, substantially as described.

2'. Ina bell of the class described, a central post; a hammer-carrier rotatable thereon and having an attached pinion provided with a beveled hub; a locking device to at times engage and hold the beveled hub; a vibratable actuator, and gearing between it and the pinion, to rotate the latter, the actuator on its return to normal position engaging and moving the locking device into operative position, substantially as described.

The base, an upright post erected thereon, a hammer-carrier rotatable thereon and having an attached pinion; a vibratable actuator having a segmental gear; a pinion in engagement therewith and loose on the post; a locking. device. to engage and lock said pinions when the actuator is at rest, and connecting-gearing between said pinions, substantially as described.

4. The base, an upright post thereon a hammer-carrier rotatable thereon and having an attached pinion provided with a downwardlyextended hub; a vibratable actuator having a segmental gear; a pinion in mesh therewith, loose on the post and having an upwardly-extended hub; a movable lockingplate to at times engage the hubs of and restrain the pinions from rotation; and gearing intermediate the pinions, said locking-plate being moved into operative position by the actuator when in normal position, substan tially as described.

5. In a bell of the class described, a rotatable hammer-carrier, actuating mechanism to rotate it, a locking-plate to normally engage and prevent rattling of said mechanism, and means to release the plate when the bell is rung, substantially as described.

6. A rotatable hammer-carrier having an upturned lug, and a hole at one end, a headed stud extended loosely through said hole and the hammer, a substantially triangular 11ammer having a convex base, and a spring secured to the lug and interposed between it and the hammer, to bear upon the convex base of and normally press the hammer and stud outwardly and maintain the hammerapeX extended radially, substantially as described.

7. A rotatable hammer-carrier, a pinion having its hub extended therethrough, a retainin g-rin g on the hub above the carrier and provided with an upturned lug, a hammer pivotally mounted near the end of the hammer-carrier, and a hammer-spring connected at one end to said lug and interposed between it and the hammer, substantially as described.

8. A rotatable hammer-carrier, a hammer having a eonvexed base and outwardly-converging sides, mounted on said carrier and having a radial and a partially rotative movement thereon, and a controlling-spring held at its inner end on the hammer-carrier and pressing upon but unconnected with the convexed inner side of the hammer, to retain it yieldingly in normal position, substantially as described.

9. A rotatable hammer-carrier, a triangular hammer having a convex base, mounted to move radially and rotatively thereon, a headed stud extended loosely through the hammer-carrier and through the hammer near its convex base, and a controlling-spring for the hammer adapted to bear upon the convex base substantially at its center, to return it to normal position, after rotative movement upon the stud, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
