ABNER lV. BARTON, OF EAST HAMPTON, CONNECTICUT.

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 617,220, dated January 3, 1899.

Application filed December 23, 1897. Serial No. 663,111. (ModelJ To all whom it may concern.-

Be it known that I, ABNER W. BARTON, of East Hampton, in the county of Middlesex and State of Connecticut, have invented a new Improvement in Bicycle-Bells; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a top View of a double bell embodying my invention, with the outer bell re,- moved; Fig. 2, a sectional view on the line a l) of Fig. 1; Fig. 3, broken views of the inner end of the central post and the center of the inner bell. Figs. 4, 5, and 6 illustrate the operation of the bell; Fig. 7, a plan view of a modified form of hammer-carrier and hammer-lever; Fig. 8, a side view of this modified construction.

This invention relates to an improvement in bicycle-bells, and particularly to that class in which two gongs are employed, the object of the invention being to constructa bicyclebell in which either a single stroke may be given, a double stroke, or a qu-adruple stroke; and it consists in connecting the end of the operating-lever with a hammer-lever and adjusting the throw of the operating-lever, whereby the number of strokes is regulated, and in certain details of construction and combinations of parts, as will be hereinafter described, and particularly recited in the claims.

While the mechanism is particularly intended for double bells, it is equally applicable for single bells. With two bells the inner bell A will preferably be secured to the upper clamp member B by the inner end of the central post 0, which post will be flattened at its inner end a to set into a groove (1. in the center of the bell, whereby the rotation of the bell on the post will be prevented. Upon the post within the inner bell is fixed a plate D, formed with an upright arm E, the purpose of which will hereinafter appear. Proj ecting upward from this plate is a lever-post F, on which is mounted the operating-lever G, which projects through a notch b in the edge of the bell A in the usual manner. This lever is actuated in one direction by a spring H, which engages with one side of the lever and with the plate D. On one side of this lever is a lug g, through which extends a screw I, arranged so as to strike the arm E as the lever is turned and so that the movement of the lever will be regulated by the projection of the screw beyond the said lug. The inner end of the lever G is connected with a hammer-lever J by a segmental link K, the said hammer-lever J being hung upon a pivot d, projecting upward from the said plate D. This hammer-lever extends across the bell and between arms 6 f of a hammer-carrier L, which is mounted upon a stud h, extending upward from the said plate I). Secured to the hammer-carrier by an arm M is the hammer N, which is segmental in shape and reversely beveled at its opposite ends, so that one end at will strike the lower bell and the opposite end n the upper bell A, which is mounted upon the upper end of the post 0. A spring 0 is connected with the under side of the hammer-carrier L at m, a point centrally between the arms 6 f, and with the central post 0, the tendency of said spring being to move the said carrier against the movement of the hammer-lever, but as the carrier turns and brings the spring to bear in the opposite direction the spring will operate to force the hammer to strike the bell, thus giving a sharp decisive stroke. The movement of the lever G by the thumb-piece G causes the link K to move the hammer-lever J so as to throw its end J to one side, as shown in broken lines,-Fig. 1, and as this end J extends between the ends 6 f of the hammer-carrier that carrier is turned against the action of. the spring 0 and so as to swing the hammer N.

. The position of equilibrium of spring 0 is found when 00 (its point of connection with the hammer-carrier L) lies in the straight line between the posts 0 and h. In this position the spring 0 is under compression, but cannot exert its energy, as it is resisted by the posts 0 and h. When 0: is forced on either side of the straight line, the spring then relaxes and carries its hammer-carrier L to one side or the other.

If a single stroke is desired, the screw I will be turned outward, so as to strike the arm E just as 00 reaches the straight line. As a: is not permitted to pass this line the ham mercarrier L is not swung on its pivot sufficiently to permit the spring o to relax and carry the hammer N on the other side of the line, and the end it consequently does not contact the bell A.

If a double stroke is desired, the screw I will be turned slightly inward, so as not to contact with the projection E until the actuation of the lever G has caused a; to approach and pass the point of equilibrium and the end it of the hammer, under the energy ot the spring 0, to contact the bell A. The lever G is then returned to its initial position under the energy of the spring II, and the end To contacts the bell A, which respective positions are shown in full and dotted lines in Fig. 4.

If a quadruple stroke is required, the screw will be withdrawn, so that the lever may be turned to such an extent as to cause the lever-arm to be first thrown outward to the position shown in broken lines in Fig. 4, so that the end at of the hammer will strike the bell A. Then the continued movement of the lever to the position shown in Fig. 5 returns the lever-arm to its former position, whereby the end at is allowed to strike the bell A. Then as the lever is released and returns to its normal position the end at of the hammer again strikes the bell A and then returns, so that the end it again strikes the bell A, a double stroke being given in each direction of the operating-lever.

The object of forming the hammer-carrier with the arms e f is that these arms may be bent toward or from the hammer-lever, so as to adjust the throw of the hammer; but instead of constructing the hammer-carrier in this Way it may consist of a coiled spring P, mounted on the post it, one end of the spring, Q, supporting the hammer N and the other end, B, ext-ending inward and turned up through a washer S and a rectangular opening T in the end of the hammer-lever J, as shown in Figs. 7 and 8. With this construction a spring 0, corresponding to the spring 0, before described, will connect the arm R of the spring with the central post 0. Otherwise the mechanism will be as before constructed, and the operation is substantially the same. By limiting the movement of the operating-lever either a single, double, or quadruple stroke may be produced.

In addition to adjusting the throw of the hammer by bending the ends of the hammercarrier the movement of the bell mechanism may be adjusted by bending the link K so as to lengthen or shorten it, and thereby increase or diminish the throw of the hammerlever.

It is apparent that the adjusting-screw I might be mounted in the arm E, so as to stand in the path of the lug g and so as to limit the movement of the operating-lever in the same manner as above described.

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