No. 440,091. Patented Nov. 4, 1890.

UNITED STATES ATENT OFFICE.

TORONTO, CANADA, ASSIGNORS BEN IRWIN, OF SAME PLACE.

OF ONE-FIFTH TO CHARLES WAR- HOLDER FOR TELEPHONE-RECEIVERS.

SPECIFICATION forming part of Letters Patent No. 440,091, dated November 4, 1890.

Application filed April 21, 1890.

To all whom, it may concern:

Be it known that we, FRANK TIFFIN TIN- NING, commercial traveler, and WILLIAM KERR SUMNER TINNING, customs-house officer, both of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have jointly invented a new and useful Holder for the Receiver of a Telephone, of which the following is a specification.

The object of the invention is to design a holder for the receiver of a telephone which may be adjusted to support the receiver level with the ear of the user of the telephone; and it consists, essentially, of securing to the wall at a convenient distance from the telephone a bracket, through the end of which is fitted an extension-arm provided with fingers designed to hold the receiver, the said extension-arm being so held in the bracket as to allow of its being vertically and longitudinally adjusted, as hereinafter more particularly explained.

Figure 1 is a perspective View, partially in section, of our holder with the receiver in p0- sit-ion for use. Fig. 2 is a similar view showing the telephone-hook weighted when it is intended to have the receiver held permanently in the holder. Fig. 3 is a sectional detail.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the bracket secured to the wall.

B is a friction-disk secured to the end of the bracket A, and O is a corresponding friction-disk, which is held in or relieved from contact with the friction-disk B on the bracket A by the thumb-screw D. The shank of the thumb-screw D extends through a hole (1 in the bracket A into the friction-disk O, and the thumb-screw D is so arranged that when the end of the shank is screwed home into the threaded hole 6 the surfaces of the disks are brought into perfect frictional contact, and the disks are thus prevented from turning in the slightest degree.

E is a sleeve forming part of the frictiondisk 0, and F is an extension-arm, which may be longitudinally adjusted in the sleeve and held in any desired position by the set-screw f. On the outer end of the extension-arm F we form a cross-bar G, on which is secured Serial No. 348,772. (No model.)

the spring-fingers g, by which the receiver of the telephone is held in position.

When it is desired to vertically adjust the extension-arm F, it is merely necessary to loosen the thumb-screw D. The arm F may then be moved into position required and the thumb-screw tightened again to hold it in that position.

In Fig. 1 we show the extension-arm F down out of the way, as indicated by the dotted lines. In this case the receiver is intended to be suspended on its hook on the telephone. In Fig. 2, however, We show a weight H, suspended on the hook to take the place of the receiver, which is intended to be held permanently between the spring-fingers 9. We attach the weight H to the telephonebox by a chain 77., so that when it is desired to use the telephone it is merely necessary to remove the weight H oif of the hook and to place the users ear to the receiver, which is already in position for use. From this description it will be seen that a great deal of annoyance and tediousness to the arm occasioned by the user of the telephone having to hold the receiver up to his car while waiting to receive a message will be avoided. It will also be seen that as both hands of the person receiving the message will be free he will be able to make a memorandum of any message transmitted with much greater case than at present.

What We claim as our invention is-- 1. The bracket A, having a friction-disk B formed on its end, in combination with the friction-disk O, the thumb-screw D, and the extension-arm F, secured in any desired position in the sleeve E by the set-screw f, substantially as and for the purpose specified.

2. The bracket A, having a friction-disk B formed on its end, in combination with the friction-disk C, thumb-screw D, and extension-arm F, which has formed on its outer end the cross-bar G, on which are secured the spring-fingers g, substantially as and for the purpose specified.
