Patented March 12, 1907- Application filed November 12. 1906. Serial No. 343,122.

T0 all whom, t may concern/.-

, Be it known that I, ELMER R. CONNELL, a citizen of the United States, residing at Keyser, in the county of Mineral and State of West Virginia, have invented a new and useful Clock, of which the following is a speciication.

This invention relates to striking clocks, and has for its principal object to provide a means in the nature of an attachment which may be applied to existing clocks for the purpose of more fully designating the time at the half-hours.

A further object ofthe invention is to provide an attachment for ordinary ,clocks which strike both the hour and half-hour, by which after the single stroke denoting the half-hour a separate gong will sound the full hour.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly` pointed out in the appended claim, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacri'licing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a front elevation of a striking clock provided with an auxiliary striking means arranged and constructed in accordance with the invention. Fig. 2 is a detail view illustrating merely the arrangement ofthe striking-levers and their connections. Fig. 3 is a detail view of a portion of the attachment looking from the rear.

Similar numerals of reference are employed to indicate corresponding parts throughout the several iigures of the drawin s.

In Fig.. l is illustrated an ordinary eightday clock A, having a gong B, which is struck by a hammer C at each hour and once at each half-hour. The hour periods are under the control of a striking-wheel D, which is engaged by a lever E, the latter being moved to release position by a small crank F, carried by the main arbor G. At the end of the half-hour periods the crank F engages a lever Hwhich is connected to and operates the hammer C in the usual manner. In addition to this mechanism an auxiliary striking-train I is employed, this mechanism including a striker-wheel J, a lever K, a hammer L, and gong M, the latter being diiferent in tone from the gong B. The main arbor G is preferably extended some little distance beyond the back of the mainframe, and to its outer end is adjustably secured a crank-arm 10, the latter being locked in place by a setscrew 11, so that it may be revolubly adjusted and made to correspond accurately to the main crank F. This crank 10 is arranged to engage a lever 12, that is mounted on a pivotpin 13, carried by a disk 14 at the rear of the frame, and said lever is connected by an arm 15 to a crank-arm 16, that is carried by a loose arbor 17, said arbor 17 being provided with an adjustable rocker-arm 18, that is enranged to engage the controlling or locking lever K of the striker-wheel J. l

In operation the main clock mechanism will operate in the usual manner at the end of each hour to allow the hammer C to strike the gong D, and at the end of each half-hour the crank F will engage the arm Hand after wiping past the latter the hammer C will be moved against the gong D, the hammer making but a single stroke to denote the halfhour, as usual. At the same time the crank F leaves the arm H the auxiliary crank 10 will have engaged the lever 12, and forcing the latter down against the stress of the spring 20, and its movement will be transmitted, through the rod 15, to the arm 16, rocking the arbor 17, and the rocker-arm 18 will then lift the lever K of the auxiliary striking-train, so that the latter will operate on the hammer L and the gong M will be sounded a number of times corresponding to the previous hour, or, in other words, if the time be half-past three the hammer C will make one stroke,

and then the hammer L will make three strokes, so that the time will be clearly noticed, and as the gangs difler in tone there can be no confusion in the reading of the time.

The disk 14, which carries the pivot-pin 13, is revolubly adjustable, so that the secondary striking-train'may be placed in any position with reference to the main clock in accordance with the size of the clock-casing or the construction and arrangement of the parts, this being especially valuablewhere the device is used in connection with tower-clocks and the like.

I clairn- An attachment for striking clocks of that IOO IIO

Glass in which both the liour and half-hour are sounded, comprising an auxiliary gong, an auxiliary hammer, an auxiliary strikingtrain, a Controlling-lever for the latter, a rocker-arm 'for operating said lever, an arbor carrying said rocker-arm, a crank-pin on the arbor, a Crank-pin adjnstably secured to the main arbor of the clock, a disk adjustably mounted at a point adj aeent to the arbor, a pivot-pin Carried by the disk, a lever mounted on the pvot-pin and arranged to be engaged by the adjustable crank, and a connecting-rod extending between the disk-earried lever and the arbor Crank-pin.

In testimony that I Claim the foregoing as my own I have liereto allixed my signature in the presence of two Witnesses.
