HOWARD J. TREG-ANZA, OF NEW YORK, N. Y., ASSIGNOR TO THE ANSONIA CLOCK COMPANY, OF NEW YORK, N. Y., A CORPORATION OF CONNECTICUT.

CLOCK.

Specification of Letters Patent.

Patented July 14., 191-1.

Application filed March 14, 1913. Serial No. 754,294.

To all whom it may concern:

Be it known that I, HOWARD J. TREGANZA, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Clocks, of which the following is a specification.

My invention comprises a novel clock switch arranged to permit or prevent the striking of the bell hammer, the switch being slidably mounted on the clock case and movable in a right line toward and away from the clock face.

The object of this invention is to provide a switch of the above character which will be novel in construction and operation; which will be very simple and inexpensive to manufacture; and which will be mounted on the case entirely separate from the other members of the clock.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents an alarm clock in top plan with my invention applied thereto, a portion of the bell and handle being broken away to disclose the alarm and striking hammer, and the opening in the case through which they project, Fig. 2 is a detail back view of the clock, Fig. 3 is a detail section taken in the plane of the line AA of Fig. 1, Fig. 4c is a detail section taken in the plane of the line BB of Fig. 2, and Fig. 5 is a detail section taken in the plane of the line CG' of Fig. 2.

The clock case is denoted by 1, a portion of its works by 2, its bell by 3 and its time and alarm hammers by 4 and 5, respectively. These hammers project through an opening 6 in the case and are operated to strike the bell in the usual manner.

' The switch comprises a slide-member 7, a stop member 8, and a handle member 9. A track for the slide member 7 of the switch is provided, in the present instance by striking up a portion of the case to form an elongated recess 10, within which recess the slide member 7 of the switch is fitted to be reciprocated.

An elongated slot 11 is out through the wall of the recess, within which slot the shank 12 which connects the handle member 9 with the slide member 7 is fitted to slide. The slide member 7 of the switch is preferably bowed so as to increase the frictional engagement of the slide member and the handle member with the case to retain the switch in its adjusted positions against unintentional displacement. The stop member 8 projects from the slide member 7 a sufficient distance to permit its free end to be brought into and out of the path of the alarm hammer 4: to prevent or permit the alarm hammer to strike the bell 3 as desired.

The slide member 7 and the stop member 8 are preferably formed integral from a single piece of metal thus materially simplifying the switch.

By forming the track for the slide member by striking up a portion of the case, a very simple and inexpensive means are provided for guiding the slide member in its movements.

What I claim is 1. In a clock, a bell hammer and a switch slidably mounted on the case and movable in a straight path at right angles to the clock face and across the path of and directly engaging the hammer.

2. In a clock, a bell hammer and a switch slidably mounted on the case, comprising interior stop and slide members and an eX- terior handle movable in a straight path at right angles to the clock face to bring the stop member across the path of the hammer to directly engage it.

3. In a clock, a case having an elongated recess and a slot through the wall of the recess, a bell hammer and a switch comprising a member slidable in said recess, a stop member inside the case and a handle member outside the case, operable to move the slide member into position to bring the stop member across the path of and directly engaging the hammer.

4. In a clock, a case having an elongated recess and a slot through the wall of the recess, a bell hammer and a switch comprising a member slidable in said recess, a stop member inside the case and a handle member outside the case, operable to move the slide member into position to bring the stop member across the path of and directly engaging the hammer, the slide member being bowed to increase the frictional engagement of the slide and handle members with the case.

5. In a clock, a case having portions struck up from the inside to form an elongated recess and a slot cut through the Wall of the recess, a bell hammer and a switch c0mprising a member slidable in said recess, a stop member'inside the case and a handle member outside the case operable to move the slide member into ncsition to bring the stop member across thepath of and directl engaging the. hammer.
