.and perfectly. I attain this object by the mechanism illustrated in the accompanying drawing in which- 7 Figure l 1s an elevat onof the-complete structure showing parts in section; F 1g. 21s
an elevation of the same structure "at right angles to Fig. 1, also showing a partial section along the line A B of F ig.'1; Fig. 3 isan elevation of a modified and simplified form of the headband; Fig. 4 is an elevation of the same structure at right angles tol lg.
. 3; Fig. 5 is an'elevation' ofzthe mechanism as applied to a single receiver; and Fig. 6 is an elevation of a part of the same mechanism at right angles'to F1g. 5.
In Figs. 1 and 2 numerals l and 2 designate two strap-springs which go over the head and-produce the necessary pressure on the receivers. The extremities of these straps are perforatedand receii'e the adjust able holders 3. v Washers l which are riveted onto the holders 3, coiiperate withthe integrally formed flanges on the latter to clamp the straps l and 2 together with sufiicient' friction to hold the straps in adjustment with respect to each other after beingset.
" Apertures in the holders 3 receive slidable rods 5 which are split at oneend and formed into two arms which partly encircle the reccivcrs 8, and pivots 6, fiXed into the extremities of the arms, fit into sockets in the receivers 8 and hold them in place. Screws 7, tapped into the rdds 5, prevent them from coming entirely out of the holders 3.
In use, the straps 1 and 2 are first spread apart to the desired angle as indicated in Fig. 2, and placed upon the head. The rods '5 are'then turned in the right direction,
which adjustment is permitted by the holders 3 turning Within the perforations in the straps 1 and 2. The rods 5 are then adjusted lengthwise by sliding inthe holders 3'. Said rods'5, rotatable in the holders -3, and pivots 6 form a sort of universal joints which permit the receivers 8 to fitperfectl against the ears. After the rods 5 are holders due to the pressure of the operators head, will prevent slipping. It will be seen that no screws have tobe tightened to hold the parts 1n adjustment.

7' justed lengthwise, the binding effect in the In F igs. 3 and 4 the mechanism is sinpli fied. The springs 1 and 2, as here illustrated are made of awire. which is bent around the holders 3 and clamped firmly in position by the washers which are riveted onto the holders 3. The springs 1 and 2 and holders 3 are fixed in their relative positions, at? rwise the adjustment is the same as th the mechanism shown in Figs. 1 andet.
In Fig. .5 the mechanism is the same as that shown in Fig. 3 except that only one holder'isused and the springs l and Zen the side where the other holder is omitted,
take the form shown in F ig. 6. r i
As here illustrated, two spring straps or two spring wires are used to produce the pressure on the receivers, but if desirable, one strap orone wire may be used in place of two.
