19 and 20 is an oscillatory horizontal shaft to which is attached a depending L-shaped hammer wire 41 which carries on its lower free end a gong-engaging hammer head 42, preferably having'a felt pad 43 at its lower end. A U-shaped gong rod 44 is located beneath said hammer head and is mounted in any suitable.

manner within the clock casing 10. The striking of the gong hammer 42 against the gong wire 44 is controlled by the count wheel 26 through the strike train 23 in the usual manner.

In order to disengage the count wheel 26 from the strike gear train 23 to permit the strike mecha nism and the hour and minute hands to be immediately reset without the necessity for striking the clock'around", provision is made of a shiftable pinion gear 45 which normally meshes with the teeth of the count wheel 26 and is slidably fitted upon the squared end 46 of a shaft 47. The pinion gear 45 is adapted to be pressed for wardly at all times on the shaft 4'? into mesh with the count wheel 26 by means of a forwardly plate 19 by a screw 53 driven into a bushing 54.

The spring lever 52 is provided with a central elongated slot 55 through which the squared shaft 46 is adapted to protrude, and thus permitting said lever 52 to lie flat against the front face of the shiftable pinion gear 45. A yoke member 56 is attached to the rear of the spring lever 52 and 'is provided with a slot 5'7 for receiving and'supporting the count hook 33.

The free end of the spring lever 52 has a horizontal push rod 58 extending forwardly through an aperture 59 in the dial plate 13 and having a knob 60 upon its extremity. The push rod 58 is provided intermediate its ends with an upwardly extending arm 61 having a forwardly extending button 62 preferably of a red color on its forward end. The button 62registers with an aperture 63 through which it is visible, and when the button 62 is flush with the dial plate 13, it indicates that the pinion gear 45' is in mesh with the count wheel 26. The dial plate 13 is provided with a small auxiliary dial 64 having marked thereon the figures 1 to 12 arranged at progressively increasing distances apart, as shown in Fig. 1.

The center of the auxiliary dial 64 is provided with an aperture through which extends the forward end of the hollow count wheel hub 30, the latter having a pointer member 67 detachably mounted thereon for visibly indicating in front of the dial the exact position of the count wheel The pointer member 67 is provided with a central aperture 68 having a radial slot 69 cut therein, said slot 69'being adapted to register with a corresponding longitudinal slot 70 in the hollow hub 30, I Y

The end of the key 310 opposite from the winding socket 312) has a shank '71 provided with a round socket, the interior diameter of said socket being sufficiently large to clear the squared end 310, of the key post shaft 31. The shank 71 is provided with a protruding lug 75 adapted to be inserted through the slots 69 and 70, and by means of which the count wheel 26 may be rotated to any desired position when the knob 60 of the springlever 52 is held inwardly by the operator.

Operation 1 In operation, assuming that the clock has stopped and that it is desired to set the time indicating hands and striking mechanism to correspond with the correct time, it will only be necessaryfor the operator to push the thumb knob 60 inwardly for simultaneously disengaging the count hook 33 and the pinion gear 45 from the count wheel 26. The hour and minute hands will then be set to the correct time. The operator will then insert the shank '71 of the key 31c into the hollow .hub 30 and turn the key in either direction until the pointer member 67 indicates the correct striking period for the next succeeding hour or half-hour. The key 310 may then be withdrawn and the thumb knob 60 of the spring lever 33 released.

It will beunderstood that if the count hook 33 does not then engage in one of the deep notches 28, the colored warning button 62 will not be permitted to move forward into the dial aperture 63, but will remain behind it, thus warning the operator that the key 71 must be turned one way or the other until the count wheel 26 and count hook 33 come into proper alinement.

When it is desired'to wind the main spring 24, it will only be necessary for the operator to reverse the key and insert the socket 31b thereof through the pointer aperture 68 and to turn the key in a clockwise direction.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and

all. the modifications and embodiments coming within the scope of the following claims.
