' UNITED STATES PATENT OFFICE 1 Claim.
This invention appertains to new and useful improvements in radio receivers and more particularly to a time controlled receiver.
The principal object of the present invention 5 is to provide a control for radio receivers which can be set conveniently and which will operate automatically to cut on future programs.
Another important object of the invention is to provide a time controlled radio receiver control 10 means wherein the construction is simple and far from being as complicated as the structures represented in prior patents.
These and various otherimportant objects and advantages of the invention will become appar- 15 ent to the reader of the following specification.
In the drawings:
Figure 1 represents a front elevational view of a receiver equipped with the novel control.
Figure 2 represents a fragmentary vertical sectional view taken substantially on line 2--2 of Figure 1. 1
Figure 3 represents a fragmentary detailed enlarged sectional view taken substantially on line 3-3 of Figure 1.
Figure 4 represents a fragmentary rear elevational view of the switch board shown in Figure 2.
Figure 5 represents a fragmentary front elevational view of the switch board.
Figure 6 represents an elevational view of the 30 motor control switch disk.
Figure '7 represents a fragmentary sectional view through the motor control switch.
Figure 8 represents a sectional view taken substantially on line 88 of Figure 7.
35 Figure 9 represents an elevational view on line 99 of Figure 7.
Figure 10 represents a diagrammatic View disclosing the electrical connection between the electrical devices involved.
40 Figure 11 represents a modified form of hour and minute hand contacting structure.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the cabinet construction including the front wall 5. This receiver may include the usual tuning dial 6 in the manual controls l. Numeral 8 generally refers to the automatic control. As is clearly shown in Figure 2,.the front wall of the cabinet is provided with an opening '9 therein and behind this wall 5 and extending behind this opening 9 is the switch board l0 having suitable brackets II on the back thereof for supporting the clock l2. From the clock l2 extends the tube IS on which the hour hand It is located and through this tube l3 extends the shaft on which the minute hand I5 is secured.
On the switch board It] and concentrically arranged with respect to the axis of the hand 5 |4l5 is the row of contacts I6 against which the spring projected brush I! on the hour hand wipes. 4
Numeral I'l represents an annular conductor ring with which the spring projected brush I8 on the minute hand l5 wipes.
It will be observed in Figure 10, that numerals I9, 2|], and 2| represent the station line and of course there can be as many more of these station lines as desired. Obviously, if the station 15 lines I9, 20, and 2| are increased, the number of contacts l9a, a, and 2la must be proportionately increased. For each quarter hour duration of the program there is a switch which if the apparatus is only constructed for reception of 20 three stations, naturally employs the three contacts 19a, 20a, and 2 la along with the contactor 22. Two annular partitions, one inner and one outer denoted by numerals 23-24 respectively are provided between the cabinet front 5 and the switch 25 board I0 and are provided with openings through which the guide rods 25 extend, along which the contactors 26 are located. One contactor 26 for each group of safety contacts 19a, 20a, and 2Ia and more if desired.
The contactor 26 consists of a collar 21 slidable on the rods 25 and provided with a knob 28 which extends'through a corresponding slot 29 in the front wall 5 of the cabinet. The slots 29 are radially disposed with respect to the opening 9. The contacts [9a, 20a, and 2Ia are of the spring clip type, while on the collar 26 is the knife blade 30 for engagement with the clip like contact. Obviously whichever station is desired is determined by moving the blade 30 to engage its contact, whether it be l9a, 200. or 21a.
For actuating the tuning shaft or tuning dial of a radio receiver (not shown) a pair of motors 3|- 32 are employed and provided with a common" shaft 33 on which is located a pulley 34 (or a sprocket wheel if desired) which drives the shaft 35 through the medium of a belt 36' (or sprocket chain if desired). On this shaft 35 is the dielectric disk 36 which on one side is provided with the outside annular conductor strip 31 having a break therein, the inside conductor strip 38 having a break therein and the intermediate contact strip 39 having a break therein, these breaks being located at offset positions with respect to each other as defined in Figure 6. v
On the other side of the disk 36 are the annular unbroken conductor rings 40-.
20 Thus it can be seen when the clock hand reaches the closed switch set for a given program, one of the motors 3l32 will be energized through the medium of the switch generally referred to by numeral 58 in Figure 7 to the end that the circuit will be maintained open for a period of fifteen,
minutes at the end of which the motor will be shut ofl unless the adjacent switch of the control shown in Figure 1 is set to work in continuation of the program.
Figure 11 shows a slightly modified form of contacts for the hour and minute hand. In the opening 9 of the cabinet front an annulus 59 of dielectric material is provided with the stepped K shoulders 606|. On the shoulder Si is located 35 the annular conductor strip l'la. for the spring projected brush i8a of the minute hand while on the shoulder 60 is the annular arrangement of contacts i6 with which the spring projected brush 62 of the hour hand I 4 is engageable.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.
Having described the invention, what I claim as new is:
In a time controlled receiver, a cabinet structure including a clock mechanism having an hour and a minute hand, a collector ring for one of the hands, a plurality of contacts annularly arranged for the other hand, said collector ring and contacts being mounted on the face of the clock against which the hands wipe, said cabinet having a front wall provided with an opening therein, said clock face being located inside of the cabinet and forming a backing for the opening, said face extending on its periphery beyond the'limits of said opening, and in spaced relation to the back of the front wall, the front of the cabinet being provided with a plurality of slots radiating from the said 'opening therein, a conductor rod mounted in the cabinet between the outer portion of the clock face and the rear part of the front wall and adjacent each of the slots, a slider on each of the rods provided with a handle protruding through the corresponding slot, the outer portion of the clock face being provided with a plurality of annular rows of time contacts arranged concentrically thereon, and blades on the slider for engagement selectively with the said last mentioned contacts.
