ALARM-OLO CK.

Speccaton of Letters Patent.

Patented July 15, 1913.

To all whom t may concern:

l Be it known that l, GEORG Brani?, a subject of the German Emperor, and residing at Schramberg, lVurttemberg, German Empire, have invented certain new and useful improvements in Alarm-Clocks, of which the following is a specification.

The present invention has reference to improvements in alarm clocks, and relates more particularly to means for arresting the alarm device proper, and the particular object of the invention is to provide means in connection with an ordinary alarm clock which, upon the clock being tilted or laid over, slide of themselves into the position where they arrest the alarm works. This, obviously, constitutes a great improvement over the ordinary arresting` means, consisting of levers, keys, knobs or the like, which are not easily located at night, and the operation of which generally requires the use of both hands, one for holding' the clock and the other for actuating the arresting member, whereas in my device only one hand is required to grasp the clock and tilt it for a moment or lay it over on its face, when the alarm works will at once be stopped, until released again by manual operation of a pull key of knob.

The nature of my invention will best be understood when described in connection with the accompanying drawings, in which- Figure l shows a side elevation of an alarm clock, part of the casing being broken away to expose the partsl constituting my invention. Fig. 2 shows a fragmentary rear view, with the rear plate removed. Fig'. 3 shows a clock in tilted position, with the arresting device in operative position.

The anchor-arbor a of the alarm works carries near one end the anchor Z) and the hammer c and near the other end the alarmworks locking-lever (Z and t-he arrestingarm e. A roller f, with troughed circumference, is fixed on the shaft it, which latter is slidingly journaled in the works-plates g, g and whose rear end projects through the rear wall of the clock casing a' and carries at its extremity a key or knob 7c. The alarm-works is ordinarily arrested in any well known manner, for instance by the stop and release spring Z cooperating with the locking lever CZ, when the anchor arbor a assumes the position, shown in full lines in Figs. l and 2, the arresting-roller j. lying sidewise of the arresting-arm c.

Upon the alarm being released at the set time the release-spring Z moves from the broken-line position in Fig. l into the fullhne position, so that the lever Z of the alarm works is now released and the alarm is sounded.

F or the purpose of arresting the alarm, a tilting' of the clock, as shown in Fig. 3, suffices to cause axial displacement of the shaft t, with the result that the oscillating arresting-arm e cooperates with the roller i and is retained in the circumferential groove thereof, thereby promptly stopping any further alarm operation. The drive of the alarm works, that is the tooth-pressure with which the toothed wheel m acts on the anchor pallets, serves to keep the arm e pressed into the roller trough, so that an inadvertent release of the arresting device is not to be feared. For intentional release of the arrester the knob or key lo is to be pulled out.

Obviously the arresting members may also be so disposed that they operate upon the clock being tilted in some other direction than that shown here by way of example.

What I claim as new and desire to secure by Letters Patent is l. In an alarm clock, in combination with the alarm works of the oscillating anchor type, an arresting arm extending from the anchor arbor of said alarm works, and means sliding into cooperation with said arresting arm, for the purpose of arresting the alarm operation, upon the clock being tilted.

2. In an alarm clock, in combination with the alarm works, means for arresting the said alarm works, comprising an arresting arm extending from the oscillating member of the alarm works, an axially slidable shaft, and al roller thereon adapted to be brought into cooperation with said arresting arm upon the clock being tilted.

3. In an alarm clock, in combination with the alarm works having an oscillating arbor, an arresting arm extending from said ostained in this position until a pull is exerted on said handle.

In testimony whereof I affix my signature in presence of two Witnesses.
