ARM-REST FOR TELEPHONE USES.

SPECIFICATION forming part of Letters Patent No. 327,692, dated October 6, 1885.

Serial No. 154,511. (No model.)

To all whom, it may concern:

Be it known that I, FRANK G. JOHNSON, of the city, county, and State of New York, have invented new and useful Improvements in Arm-Rests for Telephone Uses; and I hereby declare that the following is a full, clear, and exact description. of the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to a new and useful device for an arm-rest to be employed in connection with telephones for the purpose of re lieving the telephone-operators of the usual fatigue, which is caused byholding to the ear for a considerable time the telephone-receiver, and at the same time so constructed and employed as not to limit in the least the free 1110- tion,in all lateral directions,ofthe elbow,hand. arm, or body of the telephone-operator, and so arrranged, too, that it can be employed on either side of the telephone-transmitter and by persons of different heights.

My improvement whereby I attain these results consists of a hanging or pendent support for the elbow or hand, which is held or supported at the upper end by being suitably attached to the side wall, by means of a hook or staple, or, preferably, by means of a projecting and adjustable-bracket attached to the wall near to and on either side of the telephone-transmitter, as illustrated by the accompanying drawings, in which- Figure 1 is a perspective view showing the device in use. Fig. 2 is a view of the suspension-rod that supports the arm-piece 13, shown as attached directly to the wall of the room; Fig. 3, a View of the projecting adjustable bracket, from which is suspended the hanging-rest; Fig. 4, a view of the arm-piece, seen from the liner min Fig. 2; Fig.6,a view showing the method of supporting the arm by means of grasping the arm-piece and the telephonereceiver with the hand instead of placing the elbow upon it; Fig. 7 shows a modification of the suspensionrod and arm-piece, and Fig. 5 shows how the suspension-rod can be modified so as to employ the telephone-receiver itself as the arm-piece by grasping it with the hand.

Similar letters refer to similar parts throughout the several views.

The supporting-bracket O,which is fastened one of these brackets may be placed on either side of the transmitter to accommodate left as well as right handed persons in the use of the rest.

To suit persons of different heights the sup porting'bracket is provided with a long vertical edge or bar, having upon its outer edge a series of suitable hooked projections, c c. This bracket 0 is also extended so as to project out from the wall upon which it is fastened, so as to bring the hooked projections 0 o in nearly a vertical line with the natural position of the elbow and hand of the operator when standing in a convenient position beforethe transmitter, to prevent the necessity and effort of drawing the SLISPGDSlOD-I'Od A A much out of the vertical line of its sup port on the bracket.

A A are the suspension-rod or support of the arm-piece B, which consists, preferably, of a metallic rod, bentin the form of asmall semicircle at the top, to furnish a convenient means of hooking or attaching it to and detaching it from the supporting-bracket O. or other support, in order to adjust the rest to persons of different heights. The arm-piece B is made, preferably, fiat and partially semicircular to better fit the arm, and is attached to the suspensionrod, at b b; or it (the arm-piece) may be a straight round bar, or of any other suitable shape if only it is long enough between the points I) b to freely admit the elbow or hand to pass between the two branches of the suspension-rod A A.

Instead of placing the elbow upon the armpiece B, the telephone-receiver and the armpiece B can be grasped together in the hand, as shown in Fig. 6, which rests the arm as effectually as if the elbow rested on the armpiece, only, in this mode of using the rest,the suspension-rod A A needs to be raised higher on the adjustable supporting-bracket or wall.

Instead of making the suspensionrod A A in two parts, as shown in Figs. 1 and 2, it may be made single, as shown by A, and be provided with a straight cross-bar, as b, Fig. 7, in which case the cross-bar b and the telephone-receiver are grasped together in the hand, as shown in Fig. 7.

Figure 5 shows the method of using the rest by attaching the suspension-rod A directly to the telephone-receiver T. as shown by b, and thus utilizing it (the receiver) as the armpiece.

Ofcourse,in the use of the word arm-piece in this specification I do not limit myself as signifying that the elbow only is to be placed upon the rest to relieve the arm, as the arm is afforded rest when its weight is supported by placing the arm upon the rest-,orby grasping the rest with the hand.

The rest is adjustable to persons of different heights by simply hooking the suspensionrod A A onto any desired projections c c of the bracket, as shown at a, Fig; 1, or at such different elevations on the wall as will suit the height of the person desiring to employ the telephone.

By the employment of the suspension-rod A A as the support of the arm-piece B it (the arm-piece) is rendered freely mobile in all lateral directions, which, therefore, prevents any restraint upon the free motion of the hand, arm, or body in a horizontal plane while employing the rest, which result is indispensable to the convenient use of the telephone.

I do not limit myself to any particular form or style of supporting-bracket, as I am aware that a great variety of these may be madeas, for instance, a series of pins or separate hooks may be placed one above another instead of a bracket made in a single piece for the securing the suspension-rest to the wall, or even a single support attached to the wall may be employed, as shown by Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with a transmitter of a telephone, the hanging arm-rest, consisting of the suspension-rod A A and arm-piece B, attached to the side wall, D, above and at the side of the telephone-transmitter, substantially as and for the purposes set forth.

2. The combination, with a transmitter of a telephone, of the supporting-bracket G, having any desired projections c c, and hanging armrest, consisting of the suspension-rod A A and arm-piece B, substantially as and for the purposes described.

FRANK G. JOHNSON.
