UNITED STATES HARRY WONG, 0F DULUTH, MINNESOTA.
ALARM CLOCK.
Application led February 2'8, 1925. Serial No. 12,193.
lTo all whom t may concern:
Be it known that I, HARRY VVONG, a citizen of China, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Alarm Clocks, of which the ollowing is a specification, reference being had therein to the accompanying'drawing.
This invention relates to improvements in alarm clocks and has special reference to electrical connections for same for controlling mechanism a art from the clock.
The principal o ject of the invention to provide simple and practical means whereby the predetermined operation of the alarm clock may be made to control electric energy imparted to another object, such for example as lighting or cooking utensils.
Another object is to provide novel and convenient means for the positive setting of the clock whereby the desired predetermined duration of time of operation of the secondary device may be accomplished.
Other Iob'ects and advantages of the invention will appear in the further description thereof. Y Y
Referring now to the accompanying drawing, forming part of this application, and in which like reference characters indicate like parts:
Figure 1 is a wiring diagram of the-electrical connections with the clock;
Figure 2 is a face view of .the clock mechanism with the clock dial removed; fFigures'I 3,14 Yand 5 arefsuccessive steps in the' circuit making and breaking device within ther clocki and p ,Figure ,67's a side elevation of the setting Yand*v electric ,circuit control cam.
1 represents the circumferential wall of a common circular alarm clock to one inner lpheripheral face of which is attached the insulate switch block 2, pivotally carrying, as
. at 3,y t e switch arm 4, by the swinging of 45#f which either one of the two electric circuits subsequently described may be opened or closed, or both allowed to remain open.
A common electric socket 5 is installed on the outer circumferential edge of the clock into which any desired electric circuit may one controlling the lamp 6. One wire 7 of the light circuit leads into the socket 5 and is connected to the terminals 8 and 9 of the switch 2, and the other wire 10V of the light circuit extends from the socket 5 to theterminal 11, thence by means of the wire 12 to one side 13 of the circuit control mechanism within the clock.
.The opposite side of the circuit control within the clock comprises the dat resilient member 14 to 'the binding post of which is attached the wire 15 leading to the terminal 16 upon the lower end of the switch 2. Intermediate of the terminals 8 and 16 is the blank terminal 17, while intermediate of the terminals 9 and 11 is the blank terminal 18 ;y these blank terminals being for engagement with .the switch arm 4 when the circuits are inactive.
19 represents the frame of the clock works, upon the side of which adjacent the switch 2 is mounted a strip of insulation indicated at 20 upon the lower end of which and spaced outwardly therefrom is securely fastened the sprin terminal 14 as at 21, the binding post o said terminal being indicated at 22. This spring terminal is preferably long and flat, carrying strips of insulation upon both sides thereof, except upon the extreme free end where it is intermittently en aged by the flat contact member 23 carrie upon the rockable arm 24 pivoted upon the insulated strip 20 as at25. This rockable arm is held normal] in the position shown in Figure 2 of the rawings by means of the spiral spring arm 26, and the contact 23 is slidably engaged at al1 times upon the plate 27 upon the insulated strip 20, and the wire 12being connected to this plate and the terminal 11 of the switch 2 forms a circuit intermediate of same.
Now, when the insulated arm 24 is swung downwardly against the action of the spring 26 by thel arm 28, the contact between the ppint 23 and the free end of the arm 14 will opened; that is to say, disengaged, so that the arm 14 may drop below the point 23, and the elevation of said arm depends upon the action of the arm 29 which is an extension of the alarm spring bar 30 controlled by the axial action of the alarm gear wheel 31 common in all such clocks.
This mechanism is adjustable and operates in every respect in the usual manner, its action simply affecting the resilient terminal member; that is to say, this member 14 remains in its depressed circuit broken position, except when lifted by the action of the functionin of the alarm mechanism, and,`when this unctioning takes place as heretofore described, resulting in the raising beneath terminal 14 by I26, thus closin e terminal 14 an the connections carried by and beneath the f tion 4of 34 drops lidia in arm 24.
The arm 28' is normally retained in a position contraryv tol that fshown in Figure 11 in` thekactofliolding the arm 24 away from the'terminal 14 with the 'contact oint/23 outof'engagement with said arm. is acthe `arm 7is ,accomplished by the spiral spring indicated 'at 32,. the arm being held as shownby the action of the setting mechanism. mounted concentric with the hand shaft'33 of the clock, which I will now proceed to describe, it being apparent that the arm 28 is formed integral withfa similar divergent arm 34 whichiscontrll'ed by the mechanism about tobe described; A/circumferential gear dial 35 is frictionally mounted ulon the hand shaft 33 of the clock. Y Upon t is dial are annularly ,j disposed equally spaced correspondin "tothe hours of the clock, and uion the hu of the hour hand 36 of the c ock and in diametrical-'alignment therewith is a small pointer 37 the terminus of which registers with the aduations of the numbers above mentionei?r and this pointer I prefer to have colored red or made attractive in some other manner. j
The rotating of the dial for setting purposes is accomplished by the spindle 38 extending radially in re to the face of the clock and laterally beyondthe circumferential edge of same where it is equipped with a suitable thumb head 39. The inner end of this spindle is equi ped with the small beveled gear 40` whic meshes with the co "circumference ofy the dial v35 when ,t `e `spindle is forced inwardly against the expansive infiuence of the helical spring ,41, the pinion 40 being normally out of enga ment with the gear as is obvious.
Thus we have i'neans whereby the predetermined setting of the dial 35 may be made toclose the circuit control mechanism at any desired time after the tripping of the.
alarm mechanism, irrespective, of course, as to the sounding of the alarm or not.
50 represents the pointer for the alarm setting mechanism and 51 the retension d of the alarm mechanism under which the notched sleeve 52 rotates, holding the spring bar 30 downwardly until the dog drops into the notch provided for same within the sleeve, this being4 common.
Now when the "alarm is vset by themanipulation ofthe shaft thereof say for live oclock ,ai 'my and the switch bar 4 is in the position shown in F igure 1 it being desired that the li ht 6 sha1 be turned on-` for a given lengt of time after the alarm off, the dial 35 is also setto such time as 'it is desired to have the light shut olf, say at 5:30 oclock a. m. Thus the dial 35 will be set unt-il the indicator 37 is at the 5 :30 oclock mark.
With the clock set in this manner, as the hour of five oclock proac'hes, the alarm mechanism will function, raisin thefree end of the spring terminal 14 w ich will scrape it past the upwardly arched end of the ilat terminal 23 so that the latter will jump back in under the end of the spring terminal 14, thus closing the li ht circuit as illustrated by the diagram in igurel 1. Then as time pro# grosses and( 5:30 oclock arrives, the camr 43 will have rotated to that point where the y carrying with itsthe arm 28, and when the latter engages the free end of the arm will be o ned as previously described by 'drawing t e free end of said arm 24 out from under the free end of the spring terminal 14.
Now should it be desirable to prevent the clock functioning in respect to the circuit just described the switch arm 4 may be turned to parallel position with the switch block 20 resting upon the points 17 and 18 when no functioning of the circuit would result; whereas should it be desired to operate the light irrespective of the functioning of the clock the switch lever is drawn to the extreme opposite position to that shown in Figure 1, when the circuit 7 and 10 will be shorted through the switch bar as is obvious, and the common alarm mechanism of the clock used separately or in conjunction as desired.
Having thus described my invention, what I claim and desire to secure by Letters Patent., is:
1. The combination with an alarm clock having an electric circuit cooperatively associated therewith and a switch therefor, of a setting dial concentric with the hand shaft of the clock and normally rotated thereby, a cam cooperatively connected with the dial, means intermediate of the cam and'the switch whereby the latter is controlled, and means at the side of the clock and externally thereof for manually setting the dial.
Q. A device of the character described comprising an alarm clock, an electric circuit cooperatively associated therewith, means operated by the alarm for closing the circuit and manually set means concentric with the hand shaft of the clock and operated thereby for opening the circuit.
In testimony whereof I hereunto affix my signature.
