PHONOGBAPH HEARING-TUBES.

Specification oiLetters Patent.

T 0 all whom it may concern} Be itknown that .I, NELSON C. DURAND, av citizenof the United States; and a resident of Newark, in the county of Essex'and State of "New Jersey, have invented certain new and useful Improvements in 'Phonograph;

Hearing-Tubes, of which the following is a description.

My invention relates to hearing tubes for' phonographs, and the objects thereof are the provision of light, durable and rigid tubeswhich are connected to a flexibleconnectingtube in a simple and effective manner whereby the ear pieces of the tubes may readily be adjusted and retained in position in the ears of the operator.

My invention is an improvement on the construction shown in applicationof Charles L. Hibbard, Serial No. 511,443, filed August 5, 1909, for phonograph hearing tubes. In

the constrnction disclosed by the said Hibbard, rigid ear. tubes are connected to the flexible tubing by means of a rigid Y connection, the arms of which are connected to the metallic ear tubes by flexible connections, the position of the ear tubes being regulated by a-friction device mounted between the same. In my construction, I providea connection between the flexiblettubing and the .ear tubes,which is in effect a' Y connectiomthe arms of which are adjustable toward and from each. other, and are held in adjusted position by friction. The ear tubes are connected directly with the arms of the Y.- By the construction indicated, I do away with the flexible tubing between the arms of the 'Y and the metallic ear tubes, and. with the friction" device mounted across the lower ends of the ear tubes.

Other objects of my invention consist in the construction ofv partsand combinations of elements as hereinafter more particularly described and pointed out.

Reference is hereb made to the accompanying drawings orrning part of this "specification and representing a construction embodying my invention, in which- Figure 1 represents a side elevation of a pair of ear tubes and connected parts. Fig. 2 is'a cross section on line 2+2 of Fig. 1, the holding screw being shown in side elevation. Referring to the drawings, ear tubes 1, 2

- are preferably of metal or other rigid conthereinto.

struction and are provided with car tips 3, 3 of soft rubber or other suitable material which may be adjusted in the ears of the operator, and which may be renewed when necessary. The tube 1. at its lower end is secured within a short tubular portion l of the hollow body or barrel 5 having an ex tension at right angles to the portion 4. The tube 2 is connected in like manner to the'liollow barrel 6, which latter has a tube 7 integral therewith or secured thereto openin into the interior of barrel 6 substantially 1n line with the opening of tube 2 This tubular extension 7 is con nected to the flexible tubing 8, the lower end of tube 7 being inserted within the upper end of flexible tube 8 or otherwise connected thereto. Tube 8 leads to the phonograph reproducer.

The hollow members or barrels 5 and 6 are vmounted with their open ends axially in eled surface 9 by any suitable means as the screw 10 extending axially through barrels 5 and 6. A split washer or other suitable friction means 11 may be interposed between the head of the bolt 10 and the outer surface of one of the barrels, as5, to'regulate the pressure exerted upon each other by barrels 5 and 6. As shown in the drawings, the tips 3 of the ear tubes 1 and'2 are di- *Patented May'12, 1914.

rected toward each other and are so arranged that a line joining the exit openings therein invariably lics in'a plane substantially at right angles to the axis of the barrels 5 and 6 and the bolt 10. By this construction, the ear tubes 1 and 2 may be moved toward and from each other to obtain the proper adjustment of ear tips 3, into and out of the ears 'of the user, the ear tubes being held in adjusted position by the friction exerted by one barrel upon the other in the rotation of the same. It is obvious that if desired barrels 5 and 6 might telescope within each other or within a connecting intermediate tubular member, or abut -a ainst each other at their inner surfaces wit out the formation of a bevel upon the same.

Having now described my invention, what I claim and desire to .protect by Letters Patent'is as follows:

1. In hearing tubes, the combination of a pair of hollow ear tubes, anda pivotal connection between said ear tubes, the interiors of said ear tubes communicating with each other through said pivotal connection, said ear tubes having their outer or exit portions directed toward each other and so arranged that a line joining the centers of the exit openings therein invariably lies in a plane substantially at right angles to the axis of said pivotal connection, substantially as described.

2. In a device of the class described, the combination of a plurality of hollow barrelli'ke members arranged in axial alinement with each other, each member having an open end engaging and communicating with an open end in the other, means connecting said members for relative rotation about their common axis, one of said members having a hollow inlet portion, and an eartube extending from and communicating with each member, substantially as described. a

a 3. In a device of the class described, the combination of a plurality of hollow barrel-like members arranged in axial alinement with each other, each member having an open end communicating with an open end in the other, and one of said members having a hollow inlet portion, means comprising a fastening member passing axially through said barrel-like members for connecting the latter for relative rotation about their common axis, and an ear-tube extending from and communicating with each barrel-like member, substantially as described.
