UNITED s NOTIFYING ora CALL nnvrcn roa rnturrroivns. 5
Application filed. July 2 1,
T 0 all 10 ha m it may concern:
Be it known that I, GEoRen FoRs'rnR, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Notifying or Call Devices for Telephones, of which the following is a specification.
In various business houses where the telephones are kept in a central office or part of the building set aside for that purpose if acall comes in over thetelephone for a person who is not near the telephone, it is necessary for a person to leave the oifice and inform the party that he or she is desired at the telephone. Very often, due to the rush of business, the party either fails to answer the telephone or does not "answer immediately and the receiver remains off the hook of the telephone; thereby interfering with other incoming calls and causing delay of the party at the other end of the wire. a
One object of my invention is to provide a device for use in connection with telephones which will be instrumental in causing an alarm when the telephone receiver is taken off its hook in answer to a ringand continue to effect the operation of the alarm until the call has been answered by the proper person. The arrangement of the parts of my invention is such that the alarm can be silenced during the conversation.
Another object is tomake the device of my invention of a comparatively simple construction which can be easily and quickly manufactured and which can be attached to a telephone without in any way changing the structure or interferingwith the operation of the telephone.
Another object is to make the device of my invention of a durable construction and easy of manipulation.
These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which 7 Figure 1 is an elevation showing my invention applied to a telephone under normal conditions when the telephone is not in operation; the receiver hook due to the weight of the receiver thereon serving to out out the alarm,
vFigure 2 is a fragmentary section showing the device in operative position for causing an alarm, and
1920.. Serial is. 398,769.
Figure 3 shows the positionof the device" during a conversation in which the alarm can be cut out or s'ilenced even though'the receiver isofi' the supportlng hook.
Referr-ing to the drawing, 4 represents a 7 standard of a telephone of a type in general use, said telephone having a supporting hook 5 for the receiver 6; said receiver due to its weight serving to hold the receiversupporting hook 5 in the position shown in Figure 1. However, 'it will-be noted that upon removal of the receiver 6 the hook 5 will automatically move upward into the po- 'sition shown in Figures 2 and 3. -My improved device includes ahousin'g 7 wvhich may be made of wood or other insulating material and is secured to the standard 4: by any suitable securing means such for example as the clamping band 8;
The housing 7 "at its top isprovided with or includes a cavity 9 having a push button 10 mounted therein; said push button being movable upward by means of a spring 11. In other words the spring 11 servesto move the push button into 'the position shownin Figure 2. The bottom of the push button" has a contact member 12 secured thereto adapted when the push button is moved upwardly by the spring to engage two contacts 13and 14:; said contacts having posts 15 and 16 secured thereto to which the ends of electric wires 17 are respectively attached; said wires leading to an electric'generator or battery 17 and an alarm device such for example as a bell 18; it being noted that when the contact member 12' engages the contacts 13" leg portions 21 of the yokedmember extend downwardlyat the sides of thehousing and have slots22 through which pass pivot and limiting pins 23; said pins being adapted to be fixed tothe housing and serve as a swinging support for the yoked member and also as means for limiting the rising movementof the yoked member. The yoked member has a portion 24; on its head which is bent downwardly to form a cam or finger which when the yoked member is swung into the position shown in Figure 3 will engage the push button and push the latter downward so as to break the circuit. By permitting the finger 24: to remain on the top of the push button and the pins 28 to engage in the lower ends of the slots 22, the contact member 12 will be held down out of engagement with the contacts 13 and 14; thereby breaking thecircuit through the alarm device 18. Stop pins 25 may be fixed in the housings at the sides thereof and adapted to be abutted by shoulders 26 on the leg portions otthe yoked member 19 to limit the forward swinging movement of the head 20 to a position in which the finger 24 remains on the top of the push button as shown in Figure 3.
Considering that the telephone and my improveddevice are in the positions shown in Figure 1, if there is a call on the tele-' phone the receiver 6 is lifted from the hook 5 and the hook 5 will then be raised into the position shown in. Figure 2. The spring 11 will then raise the push button 10 and the contact member 12 will be moved into engagement with the contacts 13 and 1 1. This will complete a circuit through the alarm device 18 and as soon as the person who first answers the telephone finds out who is wanted, that person can be notified and the bell will continue ringing until that person answers the telephone. has reached the telephone and starts to answer, the yoked member can be swung from the position shown in Figure 2 to the position shown in Figure 3; thereby cause ing the push button to be lowered by engagement with the finger 24 and the alarm device will be silenced during the conversation. After the conversation has been completed the receiver is placed upon the hook 5. This operation swings the yoke 19 back due to the engagement of the receiver 6 with the yoke head 20 until the yoke is in its normal upright position as shown in Figure 2 and the weight of the receiver when released will cause the yoked member to be depressed to move the push button downwardly as shown in Figure 1 and thereby break the circuit through the alarm device.
While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit mvsjelf to the preciseconstruetion set forth, but consider that I am at liberty to .make such changes and alterations as fairly come with'in the scope of the appended claims.
Having thus described my invention,
