Patented Oct. 19, race..

Application filed December 2, 1908. Serial No. 465,699.

To all whom it may concern:

Be it known that I, EDWARD E. GAGE, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Clocks, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same. y

This invention relates to clocks and particularly to alarm clocks; and the object thereof is to produce an alarm clock of simple construction having the ordinary alarm attachment, and having in addition thereto a special alarm attachment which will enable the alarm to be rung very at a predetermined time.

The invention also involves a construction which enables either the ordinary' alarm, .or the special alarm to be thrown into operation whenever desired, and the invention is particularly useful in many connections where an alarm is to be given after the expiration of a short time or under certain circumstances where it is necessary for the alarm to be sounded exactly at the expiration of a predetermined time or for which the alarm is set, and they said invention also involves a construction by which periods of time necessary to perform a certain opera-' tion may be computed or determined at a glance.

The invention is fully disclosed in the following specification, of which the accompanying drawings. form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which';,

Figure 1 is a. front view of a..clock profront glassfbeing broken away, Fig. 2 a central transverse vertical sectional view of my improved clock and showing thesame on an enlarged scale, Fig. 3 a perspective .view showlng a portion of the mechanism which enables either of the alarm attachments to be thrown into operation and on anenlarged scale, and ;-Fig. 4 a section on the line 1-4: of Fig. 2 and on an enlarged scale. Referring to the drawing, 1 represents'a' clock case which is shown as circular in form,

but which may be of any suitable or desired shape and in which is mounted a frame comprising frame plates 2 and 3 connected by studs 4, any desired .number of which may .this rin i5 a dialor clock face 6 is secured,

exactly I be employed, and said frame is attached to a ring 5 secured in the case near the forward portion or front of the clock. Upon'or to and in front of the dial or clock face there is placed the usual crystal or glass front 7 through which the dial or face of the clock may be seen. i

The case of the clock is projected for wardly of the face or dial 6, and the crystal or glass 7 is rotatably' mounted in an annular keeper 6 formed bya flange 6 on the front edge of the case, and an inner annular member 5 placed within the case and between tht parts 6 and 7, and placed on the outer or front side of the dial or face plate. 6 is a flat rotatable ring 6 y The usual hour signs 6 are placed on the dial or face plate 6 within the ring 6, and

said'ring is provided with scale marks and numerals representing the minutes of an hour; the numerals beginning with five and increasing by five from left to right to sixty.

Centrally disposed within the clock and passing through the frame plates 2 and 3 is a tubular arbor 8 which carries the minute hand 9 of the clock, and this arbor projects I through the face dial or plate 6 as shown in Fig. 2.

Mounted on the front end portionof this arbor 8 is an hour sleeve 10which passes of. the clock loosely through the dial or face plate 6fand which carries the hour hand 11 of the clock, and this arbor 8 and the sleeve 10 are driven through a suitable time train, portions of which are indicated at 12 and 13, thearrangement being such that the minute hand travels at the usual speed ratio with respect to the hour hand.

At the usual point in the clock case there is mounted a main alarm setting arbor 14 such asis usually found in ordinary alarm clocks, the said arbor projecting at the back of the clock where it is provided with'a thumb and finger head 15.

The forward extremity-of the arbor 14 extends through the faceof the clock andcarries a setting hand 16, and loosely mounted on the main setting arbor 14 is the usual time wheel 17 which is driven from the time train'l3 so that the wheel 17 makes one revo- -lution in twelve hours; in other words the time wheel rotates synchronously with the hour hand of the clock. Just at the rear of the clock face or dial plate 6 the main arbor 1 1 is provided with a collar 18 having a pro; W,-

. this for releasing the alarm, a very small I back 27 of the case. That part of the'stem' 24 which passes through the crystal or glass 3 7 1s angular in form, and-'theaperture 1n 1 saidglass isv similarly formed so that the The mechanism just described is such as is "fords means for setting the alarm'to ring laterally projecting dog 29, and it should jec-ting dog 19 which runs upon the rim of I aring cam 20, which cam is provided in its edge with a notch or recess 21 which the dog 19 is adapted to enter in the usual manner. 1 The ring cam 20 is carried by the time wheel I 17 and said time wheel and ring cam are slidably mounted on the main arbor 14-.

Arranged against and transversely of the inner face of the hub of the time wheel 17 is a releasing arm 22 which is of resilient material and tends to press the time wheel and the cam 20 against the collar 18. This releasing arm may be considered as the main releasing arm for the alarm, and it may be attached to the forward frame plate 2 as shown in Fig. 3.

The arbor 14L passes through the releasing arm 22, and said arm is provided at its free extremity with alaterally projecting finger 23 which aflords means for controlling the releasing of the'alarm in a manner which will be described more fully hereinafter.

commonly found in the construction of ordinary alarm clocks. It should be understood, however, that with a construction such as degree of accuracy can be attained in setting the alarm to ring at an appointed time; this follows largely from the fact that the time wheel 17 which cooperates with the collar 18 makes only one revolution in twelve hours, and the mechanism just described will be referred to hereinafter as the hour setting mechanism for the alarm.

llhe mechanism about to be described afaccurately at the expiration of a predetermined period, say of one, five, ten, fifteen or any other number of minutes. This latter mechanism comprises a setting stem 24 which passes through the tubular arbor 8 projecting at both ends thereof, the front end thereof, in the construction shown, also extending through the crystal or glass 7, and the rear end thereof extending through the stem 24'may be rotated by turning said crystal or glass.

Near the rear extremity of the stem'24 which is rotatably mounted in the back 27 of the clock case, said stem is provided with a collar 28, which collar is provided with a be understood that this collar28 .is similar in .construction to the collar 18 hereinbefore described. 1

Mounted on the rear end extremity of the tubular arbor 8 which carries the minute hand of the clock is a ring cam 30 .whiehyis similar in construction to the cam 20, and

said ca1n30 is providedwith-a backwardly dog 29 is adapted to enter this recess when the alarm is to be released.

It will be understood that the cam 30 is fixed against rotation on the arbor 8, the reduced extremity of said arbor upon which the cam seats being preferably of the form shown in Fig.4 so as to present flat faces 32 which force the cam to rotate when the arbor rotates. At the same time it should be understood that the cam 30 may slide longitudinally upon the arbor 8 in a rearward direction from the position in which it is illustrated in Fig. 2; that is, toward the collar 28.

Lying against the inner face of the cam 30 is a releasing arm 33 which is substantially similar in construction and mode of operation to the releasing arm 22 hereinbefore described. This arm 33 is of resilient material and tends to force the cam 30 in the direction of the collar 28, and said arm may be attached in any suitable manner to the rear plate 3 of the frame. The upper extremity of the releasing arm 33 is bent inwardly to form a releasing finger 3 1, and this finger 3 1 controls the releasing of the special alarm; that is it controls the releasing of the arm when the time for the ringing is indicated by the position of the pin 50 on the ring 6 1n this connection it should be understood that as the minute arbor 8 rotates when the minute hand carried thereby lies under the point of the pin 50, the, notch 31 of the cam 30 will have reachedlthe position of the dog 29 so that the dog will drop into said notch, and the releasing arm 33 will be thrown over into substantially the position in which it is shown in dotted lines in Fig. 2, and this movement operates to release the alarm in a manner which will appear more fully hereinafter. a

I also provide as shown in Figs. 2 and 3 a verge, shaft 35, the extremities whereof arerotatably mounted in the frame plates 2 Iand.-;3, and this arbor has rigidly attached thereto a verge 36 which may be of common form, which verge cotiperates with a verge wheel 37. The verge wheel 37 is driven by asuitable spring drum device and gearing in the usual manner, said parts being not shown for the reason that they form no part of this invention. V

Passingthrough the verge shaft 35 near one endit hereof is a trigger pin 38 which .lower end of which is adapted to operate in .1 connection with the finger 34 of the releasing arm 33. and the upper end of which ;is-provi'ded with a knob or head 39, and the central' portion. which is provided with a collar or shoulder 40, and said trigger or pin is movable through the shaft 35 vand the collar 40 prevents the same from, passing downwardly through said shaft beyond a predetermined point.

The'top portion of the clock case is provided with an aperture 41 which may have a door if. desired, and through which the I trigger'pin 38 may be operated or removed.

arm 22, and said trigger pin 42 is also provided with a collar 43 and the upper end thereof with a knob or head 44, and the top portion of the clock case is provided with an aperture 45 through which said trigger pin may be operated or inserted and removed go whenever desired. The verge shaft 35 is.

'. also provided with a hammer afm 46,which is rigidly connected therewith adjacent' to the trigger pin 42, and said hammer-arm .passes out through an aperture 47 in the top portion of the case and is provided with a ammer 48, and said hammer and hammer armlare adapted, to operate; in 'connection with the usual bell or gong49.

The trigger pin 42 is designed to control the hour alarm devices, and the trigger pin .38 is designed to control the minute or supplemental alarm devices as hereinafter described.

' Mounted in and movable through the glass 7 is a pin 50 provided at its outer end with an enlarged head 51 forming a handle, and between which and the glass 7 is a spiral spring 52, and said pin is adapted to engage a stop 53 .on the rotatable ring 6 and said pin 50 is also provided with a stop pin 54 to limit the outward movement thereof.

With this description and the accompanying drawings, the operation will be readily understood in view of the following statement thereof.

In practice, in order to set the alarm for minutes, the hour alarm trigger 42 is removed, and the rotatable glass front 7 is turned to the left by the pin 50. In this operation by pressing the pin 50 inwardly it will engage the lug 53 which is over the 60 mark on the ring 6. The glass 7 and ring 6' may then be turned' tillthe 60 or zero mark is directly under the minute hand as shown in Fig. 1. By releasing the pressure on' thepin 5O -it-will move outwardly'and disengage the lug 53 on the' ring 6, and if it is desired to set the alarm for 34 minutes, the glass 7 is turned from right to left by means of the pin 50 till said pin is directly over the 34-mark on the rotatable ring 6, and the glass 7 with the pin'50 is left in this position as shown in Fig.1.

In the above described operation the colthrough lar 30 will be turned by the minute arbor '8,

and when the minute hand 9 is directly under the pin 50, the dog 29 on the collar 28 will drop into the cam recess of the collar 30 which will then be moved back longitudinally of said arbor by the spring 33, and the finger 34 will release the alarm trigger 38 and the alarm will be operated.

If it is desiredv to set the clock for hours and minutes, say for example, five hours and 34 minutes, both triggers 42 and 33 are placed in. position as shown in Fig. 2. If

the time be twelve minutes of three asshown in Fig. 1, setthe alarm hand 16 for eight oclock, then set the minutealarm as before for 34 minutes. When the time is eight oclock the finger 23 onthe spring 22 which is the hour alarm spring will be released from the hour alarm trigger 42, and when the minute hand has reached the pin 50 which is directly over the 34 minute mark on the ring 6 the finger 34 of the spring arm 33 will be released and the alarm will ring exactly five hours and 34 minutes from.

the time it was set. In this way the various alarms may be operated at any desired time,

or set to'operate at any desired time, and it will be understood that the clock is provided with the ordinary alarm switch so thatthe' alarm cannot sound at any time unless the switch is open, but this device forms no part of my invention and is therefore not shown and described.

Having fully described my invention,

what'I claim as new and'desire to secure by Letters Patent, is
