The apparatus includes an electrically operated clock |2 which has as a part the 'eof a time setting mechanism It and a spring controlled delower terminus of the driving geari25, a hub diameters to provide,a shoulder.

pressor member l4 formed of an upper pivotally supported part I5, a curved part l6 which merges at its upper end into the lower end of the part l5 and a lower part H. which merges at its upper end into the lower end of the part I6. The part I1 is formed with an angularly disposed nose I 8. The part I 5 is suspended from its pivot IS.

The mechanism I3 is of normal construction,

such as the alarm setting mechanism of an alarm 10 clock with this exception, that a cam .20 constitutes a part thereof. The mechanism |3 includes an axially apertured transparent disc 2| having its outer face in the'form of a clock dial,

a setting gear 22 spaced from and opposing the inner face of disc 2|, a rotatable shaft 23, a controlling spring 24 encompassing shaft 22, a 26, a rabbeted collar 21, a sto-p'collar 28 and a nut 29. The disc 2| is mounted in the rabbet of and extends outwardly from and is retained on collar 21 by the collar 28. The collars 21 and 28 are mounted on shaft 23. The collar 21 is anchored to the shaft 23 by a pin 30. A nut 29 threadedly engages with one 'end of shaft 23 retains collar 28 on the latter. A hub 26 is integral at one end with and extends inwardly from the gear 22. The hub 26 is mounted on shaft 23 and has the cam integral with the other end thereof. The gear 25 is carried by that end of shaft 23 opposite collar 3| is mounted on shaft 23. The spring- 24 is interposed between the cam 20 and the collar 3| and frictionally clamps gear 22 to collar 21. Under normal conditions the spring 24 provides for the bodily rotating of the gear 22 with the shaft 23. The hub 26 is of two outer That portion of reduced outer diameter of the hub 26 is mounted in a support 32. Thelijhaft 23 extends rearwardly from hub 26 and t ough a support 33. They peripheral shoulder on hub 26 abuts support 32. The cam 20 has a high edge part 34, a lower edge part 35 of less length than the edge part 34 and a shoulder 36 at-which' the lower end of edge part'35 terminates. The other end of edge part 35 merges into edge part 34. e

The edge part 35 and shoulder '36 provide a notch. The gear 25 is operated from a train of gearing 31 The gear 22 has its outer face provided with a pointer 39 w ch is visible through disc 2|. A toothed stem 40 is provided for setting gear 22 relative to disc 2|.

The frame structure supporting the clock train 55 30 the end on which is'mounted the nut 29. A

driven from the clock train 381 upstanding portion shifting element 48 is the element 48 whereby 38 is indicated at 4|. The structure 4| at its bottom includes a pair of rearwardly extending spaced arms 42, 43. The latter is arranged at higher elevation than the former. Arranged below the arms 42, 43 is a resilient member 44 and positioned on the latter is a plate 45 and a plate 48 spaced from plate 45. The resilient member 44 and plate 45 are secured to the arm 42 by the holdfast means 41. The member 44 is secured to the lower is. cc of the plate 45 and the latter is arranged in spaced relation with respect to the arm 42. Secured to the lower face of member 44 and extending from one end thereof is an angle-shaped shifting element 48 for a purpose to be referred to. The element 48 includes an 49 terminating in a right angularly disposed upper terminal portion 58. Interposed between the plate 46 and the member 43 as well as secured to the upper face of the plate 45 is a metallic strap 5| formed to provide an inclined abutment 52. The nose I8 of the depressor member M is for engagement with the abutment 52 for the purpose of depressing member 44 carrying the shifting element 48 therewith to the position shown in Figure 6 and for holding it in such position for a pre-determined period until the time setting mechanism is operated to an extent to provide for the cam 28 coacting on member l4 to shift it to the position shown in Figure 7. When member 44 is shifted to the position shown in Figure 7, the released and it will be caused to move upwardlydue to the action of the member 44. The arm 42 constitutes a stop for limiting the upward movement of the member 44 and element 48.

There is associated with the member l4 an upstanding controlling spring 53 having its lower portion anchored at 54 with the structure 4|. The member l4 has its pivoted end arranged above shaft 23 rearwardly with respect to the gear 22. The member I4 is substituted for the alarm actuating mechanism of an alarm clock. The lower end of part |5 of member I4 is pro--.

. vided with a depending offset angle-shaped holding member'55'which coacts with the high edge part 34 for maintaining the member l4 in position to depress member 44 against the action of controlling spring 53 which bears against the part |5 of member l4 during the rotating of the cam. The holding member 55 during the rotation of the cam will eventually engage the notch in the cam whereby pressure of the spring 53 will move part l5 of member l4 and the latter will assume the position shown in Figure '1 to release the element 48 whereby element 48 will be ele-' vated due to the action of member 44. The holding member 55 will be retained in notch in cam 28 for a pre-determined period that is tosay until the time setting m chanism is actuated to such an extent as to provide for the cam rotating to cause member 55 to ride on the high edge part of cam 28 thereby causing member H to depress member 44 and lower element 48.

Supported from the structure 4| is a hanger 56 for a knife switch 51 including a pair of bifurcated'posts 58, 59. The blade of switch 51 is indicated at 58 and pivoted at one end, as at 5| to the post 59. The blade 68 has an opening 82 and extending through the latter is the end 58 of blade 68 and element 48 are connected together. On the upward movement of the element 48, the blade 60 is shifted from the dotted line position shown in Figure 8 to the full line position thereby closing the cir-- to full line position automatically closed automatically, by a motor 89 of the clock are cuit which will be referred to. On the downward movement of element 48 the blade is shifted from full line position to dotted line position. The blade 60 is shifted from dotted line position by the time setting mechanism.

The blade 58 is shifted from full line position to dotted line position automatically from the time setting mechanism.

The blade 68 is shifted from full line position to dotted line position, that is to say to open the switch when the latter is not to be opened and manually operated element 63 consisting of a forked member 84 pivoted upon the structure 48 and provided on one of its tines 65 with an extension which projects outwardly from the back of theclock. The tine 55 has connected thereto a bar 61 disposed at right angles to the extension 66 and positioned above one end of the blade 50. When the extension 86 is shifted downwardly, the bar 61 is carried therewith and engages blade 50 to move the latter from circuit closing position to circuit opening position and to retain it on such position as long as desired.

The clock |2 includes a housing formed of two sections detachably connected together. The sections are indicated at 68, 59. The former is the front section and the latter the rear or back section. The section 58 carries the structure 4|. Section 89 has connected with the top thereof a manually operated circuit opening and closing switch indicated at 18. The switch 10 extends outwardly of and depends from the top of section 18. r

The apparatus when associated with a radio receiver may include an automatically closed and automatically opened controlling circuit and a manually closed and manually opened controlling circuit for the-power circuit of the said receiver and such circuits are shown. The said automatically closed and automatically openedcontrolling circuit for the power circuit of the radio receiver includes the conductors 1|, 12, 13 and 14. The said manually closed and opened controlling circuit includes the conductors 13 and 14. The conductors 1|, 12 extend from switch 51 to the switch 10. The conductors 13, 14 extend from switch 10 to a socket 15 which is attached to the section 69 of the housing. The conductors 13, 14 pass through an opening 16 and are connected to socket 15. The switches 51 and 18 are in parallel.

Extending from the posts 11, 18 of socket 15 are circuit conductors 19, 88 respectively connected to a plug 8| for engaging in a socket 82 attached to a power line not shown. The conductors 19, 88 are enclosedin a casing 83. The socket 15 includes another post 84, a pair of contacts 85, 86, a conductor 81 between post 11 and contact 85 anda conductor 88 between post 84 and contact 88. The circuit conductor 14 is connected to post 84. The conductor 13 is connected to post 18. Leading from the posts 11, 18 to the the circuit conductors 98, 9| respectively. The radio receiver 92 is shown as indicating a power circuit forming means arranged within a cable 93. The latter includes a plug 94 for extension into the socket 15 to electrically engage the contacts 85, 88. The power circuit is connected in a known manner to receiver 92.' The apparatus when used in connection with a radio receiver is to volume control which associates with the volume control of the receiver 92 and these controls are be provided with a,

indicated at 95, 95. The control 95 is arranged.

in the apparatus and the control 96 in the receiver. Circuit connections between the controls 95, 95 are indicated at 91 and extend through the cable 93. Control 96 is interposed in the circuit 91 which leads from the control 95. The arrangement is such that the volume may be controlled from the clock or the radio receiver.

When the switch 61 is automatically closed due to the action of the time setting mechanism with respect to the depressor member H, the controlling circuit consisting of the conductors ll, 12, 13, 14 will be closed thereby providing for the operation of the radio receiver. When the switch I is manually closed, the controlling circuit provided by the conductors 13, 14 will be closed and the receiver made active.

The time setting arrangement which is connected to the member I4, element 48 and switch 51 provides means, when the apparatus is inset in connection with a radio receiver whereby a selected broadcasting station will be automatically cut in at a pre-determined time for a predetermined period and automatically cut out at the end of such period.

The time setting mechanism corresponds in structure to and operates in the same manner as the well-known alarm setting and alarm actuating mechanism of clocks, with this exception that the cam 20 and holding member 55 are substituted for the alarm and alarm actuating means.
