TELEPHONE APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 673, 21 1, dated April 30, 1901.

Application filed October 31,1900. Serial No. 35,029. (No model.)

To all whom. it may concern:

' Be it known that I, MYER LONDON, a subj ect of the Czar of Russia, residing at McKeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements "in Telephone Appliances; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in a telephone appliance; and the object thereof is to provide a simple and effective device for securing the receiver in position during conversation.

I accomplish my object by means of the appliance illustrated in the accompanying drawings, in which Figure 1 is a front elevation of atelephone having my device attached-thereto. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged front elevation of the device detached from the telephone. Fig. 4 is a side elevation of the same. Fig. 5 is a sectional side elevation of the upper portion of the device shown upon a larger scale.

In all views similar parts are designated by numerals of like denomination.

Referring to the drawings, the numeral 1.

designates a telephone of ordinary construction. Attached to the telephone or to the wall at the side of the same is a plate2, having thereon the lugs 3 and eyebolt 4. Pivotally secured between the plate-lugs is the vertical shaft 5, having outwardly-extended lugs 6 formedthereon. Pivotallysecuredatoneend between these lugs is the arm 7. This arm is provided with a hook 8 at its rear and at its front portion with an eye 9. A hollow pulley-wheel 10 is rotatably mounted upon the upper end of the arm by means of the screw 11. Arranged within this pulley is the spiral spring 12, which is connected at one end to the pulley and at its opposite end to the arm. Attached by one end to the periphery of this pulley-wheel is the cord 12', which extends downward and connects at its opposite end to the eyebolt 4: of the plate. Rigidly secured to the said pulley-Wheel is the sheet-metal casing 14, which is intended to engage about the body of the receiver and hold the same in position.

. The device when not in use assumes the position shown in fulllinesin all views. When a call is received on the telephone, the party receiving the same grasps the arm 7 and pulls it downward, as indicated by dotted lines on Fig.2. When the arm is pulled downward, the hook 8 disengages with the telephone switch-hook and atthe same time the action of the cordup'on the pulley-wheel 10 causes said wheel to rotate one-quarter revolution, thereby bringing the receiverinto alinement with the ear of the person receiving the message. When the conversation over the telephone has been completed, the arm is returned to its normal position. In returning the arm to its normal position the hook 8 again engages with the switch-hook: and at the same time the spiral spring acts upon the pulley-wheel and causes the receiver to resume its normal or.vertical position.

The arm being pivoted vertically as well as laterally permits both lateral and vertical adjustment to suit all necessary conditions.

It can be readily seen that by the use of this device in connection with a telephone a person may have the free use of both hands while receiving a message.

The detail parts of the invention may be modified in various ways without departing from the principles employed.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A telephone attachment comprising an arm pivotally secured at its base to permit vertical adjustment thereof, a hook extend- .ing from said arm to engage the switch-hook adjusted from its vertical or normal position to a horizontal position when said arm is lowered.

3. A telephone attachment, comprising an arm pivotally secured at its base to permit vertical and horizontal adjustment thereof, a projection extending from said arm to engage the switch-hook of the telephone, a receiver rotatably mounted upon the upper end of said arm, and a means whereby said receiver is caused to be adjusted from its vertical or normal position to a horizontal position when said arm is lowered. I

4. A telephone attachment, comprising an arm pivotally secured at its base to permit vertical adjustment thereof, a projection extending from said arm to engage the switchhook of the telephone, a receiver rotatably mounted upon the upper end of said arm, a means whereby said receiver is caused to be adjusted from its vertical or normal position to an approximately horizontal position when said arm is lowered, and a spring adapted to aid in restoring the receiver to a vertical position when the arm is in its normal position.

5. A telephone attachment, comprising an arm pivotally secured at its base to permit Vertical and horizontal adjustment thereof, a projection extending from said arm to engage the switch-hook of the telephone, a receiver rotatably mounted upon the upper end of said arm, a means whereby said receiver is caused to be adjusted from its vertical or normal position to an approximately horizontal position when said arm is lowered, and a spring adapted to aid in restoring the receiver to its vertical position when the arm is being raised to its normal position,

In testimony whereof I have hereunto affixed my signature in the presenceof two subscribing Witnesses.

MYER LONDON.
