1 Claim.

The present invention relates to new and useful improvements in radio clocks and has for its primary object to provide, in a manner as hereinafter set forth, novel means whereby a radio receiving set may be automatically turned on at any desired predetermined time.

Another very important object of the invention is to provide a radio clock of the aforementioned character which is adapted to be expeditiously installed for operation on receiving sets which are already in use.

Other objects of the invention are to provide a radio clock of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation of an embodiment of the invention.

Figure 2 is a rear elevational view with a portion of the insulating cover of the clock broken away in section.

Figure 3 is a view in side elevation, showing the upper portion of the insulating clock cover broken away in section.

Figure 4 is a fragmentary view in vertical section, taken substantially on the line 4-4 of Fig. 2.

Figure 5 is a fragmentary view in front elevation, showing another form of the invention.

Referring now to the drawings in detail, it will be seen that the reference numeral I designates a radio cabinet. Mounted in the cabinet I is a conventional receiving set which is designated generally by the reference numeral 2 (see Fig. 2). The reference numeral 3 designates a combined electric switch and volume control shaft for the receiving set 2 which projects from the front of the cabinet I. Fixed on the shaft 3 is a pulley 4.

Mounted on top of the cabinet I is an alarm clock which is designated generally by the reference numeral 6. The clock 6 is provided with a suitable base I. Resilient clips or clamps 8 are mounted on the rear of the clock 6 and are engageable beneath the top 9 of the radio cabinet I (see Fig. 4) for firmly securing the clock in position. The clock 6 is provided with a removable cover W of insulating material which is open at the front for permitting said clock to be observed.

On the front of the clock 6 is a dial H which is spaced inwardly from the periphery of said clock, thus leaving a marginal portion [2. Above the dial H in the marginal portion I2 is an alarm dial I 3. The reference numeral I4 designates a winding stem or key on the front of the clock which projects from the portion l2 thereof. It may be well to here state that all of the winding elements, controls, etc., of the clock are located on the front thereof.

The alarm shaft on the front of the clock 6 is indicated at l5. Fixed on the alarm shaft I5 is a pulley l6. Trained around the pulleys 4 and I6 is a belt I"! of suitable material. A suitable buckle connection I 8 is provided for tightening or loosening the belt I! as desired.

A portion of the belt I7 is graduated, as at I9, and adjustably mounted thereon is an angular arm or hook 20. The arm 20 is engageable with a stop 2i on the clock 6 for stopping the mechanism after the receiving set has been turned on to the desired volume.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, when the alarm of the clock 6 is released the pulley IS on the alarm shaft l5 thereof actuates the shaft 3 of the radio receiving set through the medium of the belt I! and the pulley 4. The initial movement of the belt 11 rotating the shaft 3 closes the usual switch controlling the electric circuit to the receiving set and continued movement of the belt adjusts the receiving set to the desired volume. The volume is regulated through the medium of the adjustable arm 20 which engages the stop 2| for arresting the belt I! after said belt has traveled the desired distance. If desired, the belt I! may be removed and the clock used as an alarm clock in the usual manner or the insulating cover Il] may be removed and the clock 6 used as a mantle clock.

In Fig. 5 of the drawings, the reference numeral 23 designates a toggle switch which controls only the electric circuit to the receiving set. In this embodiment of the invention an arm 24 is provided on the belt I! for closing the switch 23 when the alarm of the clock 6 is released. An idle pulley 25 for the belt I! is provided on the front of the radio cabinet I.

It is believed that the many advantages of a radio clock constructed in accordance with the present invention will be readily understood and although preferred embodiments are as illustrated and described, it is to be understood that further medications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is: In combination with a radio receiving set of 5 the type including a switch and volume control shaft, a pulley fixed on said shaft, a time c1ock comprising an alarm including a shaft, a izvullei fixed on the second named shaft, an endless belt trained over the pulleys for operatively con necting the first named shaft to the alarm for actuation thereby, and a stop adjustably mounted on the belt for regulating the travel thereof.

SILAS STURGEL.
