CHARLES E. BERTELS, OF WlLKES-BARR, PENNSYLVANIA, ASOSIGNOR OF ONE-HALF TO HEDLEY PEDLAR, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 543,32 8, dated July 23, 1895.
Application filed March 20,1895. serial No. 542,522. (No model.)
'ToaZZ whom it may concern:
Be it known that I, CHARLES E. BERTELS, a citizen of the United States, residing at Vilkes-Barr, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Telephone Attachment,of which the following is a specification. i
This invention relates to' an improvement in devices for holding and supporting a telephone receivingvinstrument.
The object of the invention is to provide a simple and durable device which will support a telephone-receiver in such position that it shall be adapted to the ear of the listener` and enable a person to place himself in such relation to `the transmitter and receiver as may be most convenient to him and which will enable him to have free use of both hands The invention consists in the featuresA and details of construction and arrangement hereinafter fully described, -illustrated in the drawings, and pointed out in the claims.
In'the accompanyingr drawings, Figure l'is a perspective view of my improved attachment attached to a Wall and with a receiving instrument shown applied thereto. Fig. 2 is a plan view of the same. Fig. 3 is aside elevation thereof with the receiving-instrument omitted. Fig. 4 is a detail perspective View of the swiveled arm, showing the manner of Fig. 5 is a perspective view of the stationary or wall bracket having a hinged and adjustable plate' or section. v
A Similar numerals of reference indicate corresponding parts in the figures of the draw;
Referring to the drawings, l indicates thel base-plate of a stationary wall-bracket provided with suitable perforated ears, by means of which the same may be secured to a wall or partition.
2 2 indicate a pair of forwardly-projecting parallel-ears or lugs formed integrally with the base-plate 1 and adaptedV to receive be` tween them one end of a pivoted arm 3. The inner end of `the arm 3 and the parallel ears 2 are provided with corresponding perforapivotal pin 4, threaded at its end to receive a milled or thumb nut 5 provided with au inwardly-extending :hub 6, which is adapted to bear against the` `outer face of the adjacent ear 2, by means of-fwhich the ears 2 may be 55 compressed upon-the inner end of the arm 3 for imparting the required stiffness to said pivotal joint, in order that said arm 3 may be held at any desiredv elevation by the frictional grasp of the ears 2f. At its outer end the arm 6o 3 is provided withan expanded en d 7 and an outer arm is pivoted thereto on a vertical axis 'by means oftwo parallel ears 9, formed integrally with the arm 8 and embracing and striding the expanded end 7 of the pivoted 65 arm 3, as shown. The ears 9, as well as the expanded end 7 of the farm 3, are-perforated to receive a headed bolt l0, similar to the bolt 4, above described, and also provided with a threaded end thumb-nut 5 and inwardly-ex- 7o tending hub 6, arranged and operating in a similar manner to the bolt or pin 4, above described.
In the outer end of the pivoted arm 8 an arm or block 1l is swiveled on a horizontal 75 axis, extending outwardly and at rightvan'gles to the horizontal pivot 4. AThe arm or blockv 1l is provided with a central horizontal perforation for the reception of a machine-screw 12, which 'passes through said arm or block 1 l 8o into a screw-threaded perforation in the end of the outer pivoted arm 8. The head Vof the machine-screw 12 is letJ into a recess or countersink of the arm or block 11, to give asmooth surface thereto. By means of the construc- S5 tion described the arm or block 11 is supported by the arm 8 and prevented from escaping therefrom, and at the same time is rendered capable of being'revolved,.partially or entirely, around the screw 12, which con- 9o stitutes an outwardly-projecting horizontal pivot, upon which the arm or block f11 may be turned for adjusting the angle of the receiving-instrument carried thereby. The adj acent contiguous faces or ends of the arms S and 11 afford friction-surfaces, by means of which, when the screw 12 is tightened, the arm or block 11 may be turned and held at any desired angle. i 1
The outer face or end of the arm or block roc 11 is provided with a concavity 13, adapted to partially embrace a telephone-receiver.
Upon opposite sides the arm or block 11 is recessed or grooved for the reception of the opposite ends of a clamping metallic band 14 and suitable clamping-plates 15 for securing the ends of the band 14 therein. The clamping-plates 15 are each perforated to receive a screw 16, which passes through the same and into a threaded perforation 17 in the arm or block 1l. of thin soft metal, such as brass, and is adapted to pass closely around the receivinginstrument and to be secured thereto, as above described. A set-screw 18, passing through a threaded perforation in the arm or block 11, is adapted to bear at its inner end against the horizontal pivot 12, for holding said arm in fixed relation to the pivoted arm 8, whenr desired.
In Fig. 5 I have shown how the wall-bracket may be made with a hinged plate or section 20, with the ears 2 projecting from the outer face thereof. The hinged plate or section 2O is hinged at one side to swing horizontally, and is adjusted at any angle and held by means of a screw-bolt 21, pivoted to the stationary section 1, and passing through ak perforation in and near one side of the hinged section 20, upon either side of which are milled nuts 22. By turning said nuts in a horizontal direction the angle of the arm 3 may be regulated as desired.
From the foregoing description it will be apparent that by means of the arms 3 on its horizontal pivot the receiving-instrument (indicated at 19,) may be elevated or lowered to suit the height of the person receiving a message; also, that by means of the hinged wallfbracket and the outer pivoted arm 9 and its vertical pivot the angle of the receiver with relation to the wall may be adjusted; also, that by means of the swivelcd arm or block l1 the inclination of the receiving-instrument may be regulated as found desir able. Thus the receiving-instrument may be adjusted to any position or tilted vat any desired ang-le, according to the wish of the`person receiving the message.
Having thus described my invention, what I claim is- The band 14 is made, preferably,-
1. In an attachment for supporting a telephone receiver, a stationary wall bracket or support, an inner pivoted arm hinged thereto on a horizontal pivot, an outer pivoted arm hinged to the inner arm on a vertical pivot, a swivelcd clamping arm having grooves or recesses in opposite sides thereof and journaled to the end of the outer arm on a horizontal axis at right angles to the horizontal pivot of the inner arm, a thin flexible metal band adapted to embrace and accommodate itself to a telephone receiver, and the clamping plates engaging and binding the terminais of said iexible band within the grooves or recesses in the clamping arm, in the manner and substantially as set forth.
2. An attachment for supporting a telephone receiver, comprising a wall bracket, a pivoted and horizontally swinging and adjustable plate secured thereto, a thumb nut for adjusting the angle of said pivoted section and holding the same at any angle, two pivoted and with a stationary wall bracket or support, a clam-ping arm swivelcd to the end of the outer pivoted arm sopas to be capable of being revolved relatively thereto and adapted to receivev and hold a telephone receiver, and a set screw carried by said clamping arm for holding it at the desired angle, substantially as specified.
I-n testimony that I claim the foregoing as my own I have hereto afxed mysignature in the presence of two witnesses.
CHARLES E. BERTELS.
