Specification of Letters I Patent.

Patented May 18, 1909.

.T all 'tU/LOTIt it may concern:

Be it known that we, H- RRY HiNKs-MAR- m,- ALEXANDER WILLIAM CA RON, and' PERCIVAL canes PA'QKMAN, subjects of the King of England, residing at andyvhose postoffice address is 23 Denmark Place, Charing Cross Roads, London, in the county of London, England, have invented certain new and useful Improvements in Talking-Machines and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same. This invention relates to improvements in sound conveyers for talking machines, and its object is to rovide an attachment for use with the U-tu e or goose neck of a gramophone, whereby the position of. the sound ox, with relation to the record may be changed so that the same sound box may be used, in the most effective playing position, with the hill and dale track of a raphophone record as well as with the zig-zag track of a gramophone record.

In order that the best results may be produced with the zig-zag record, it is desirable that the sound box be disposed parallel to the tone arm or tangential to the spiral track of the record, so that the needle moving in the zig-zag course will properly 0 erate the diaphragm of the sound box. 0 also with a hill and dale record, out in a disk,- the best results are produced when the needle bar. and needle are disposed inradial relation to the pivotal axis of the tone arm, with the sound box disposed laterally of the vertical plane cutting said needlesand tone arms pivotal axis and hence disposed laterally.of the spiralhill and dale track. It will be understood that, with the disk record of this type, the distancefrom the pivotal axis of the tone arm to the needle is substantially the same as the distance from said axis to the center of the rotating support carrying the disk record, so that the needle will swing sub-' stantially in an are passing through the center of the record.

\Ve are aware that it is not broadly new to provide an adapter tube or connection to enable the same sound box to be interchange ably usedwitha "hill and daleor a zig-' zagrecord. The present-invention is, therefore, not only designed to accomplish this end, but also to accomplish it in such a manand dale record 1 Her that the sound box will be properly disposed with relation to the record to produce thebest results.

To more fully describe the invention reference is had to the accompanying drawings illustrating practical, embodiments of the same, in which drawings like letters designate the same parts in the several views, and in which V Figure 1 is a view in side elevation, showing the invention associated with the goose neck of a gramophone, with the sound box in the most efic'i-tive position for playing a disk record of the hill and dale type. Fig. 2 is a plan view of same. Fig. 3 is a perspective view of the improved attachment, and Fig. 4 is ,a similar view of a modified ,form of adapter.

a shows the ordinary U-piece or goose neck ords,'the goose neck a being pivotally connected to the tone arm n to permit the goose neck a, toswing vertically.

The improved attachment or adapter consists of a tubular connection represented in Figs. 1, 2 and 3 by the curved elon ated portion I) terminating at its u per end with the lateral extension c provi ed with a pin (1 operating in the bayonet slot of the goose neck, the end 0 being adapted to be detachably connected with the open end of the goose neck member. The other, or lower, end of the elongated portion 1) of the connecting tube extends upwardly and is adapted to directly receive the sound box, the upwardly directed end 6 being providedwith a .bayonet slot f forming a locking means with the usual pin of the sound box. It is obvious, however, that any other suitable attaching means may be employed at either 01' both ends of the connecting tube. Similarly in the modified form shown in Fig. 4 the arts curved portion 1), we provide a straight tube the depending portion 6 having coin risin the ateral upper extenslon c and-the lower upwardly directed extension c.

It will be observed that when it is-desired to play a record of the fzig-zag type the improved attachment is omitted and the sound'box is directly connected with the openend of the oose neck, -butwhena -hill is to be played the attaclh ment is aflixed to the open end of the goose neck by means of the extension 0, or c, and the sound box 'is directly mounted on the upwardly directed lower portion e, or e, with the sound box in the most effective playing position relative to the record and with the needle in proper alinelnent with the axis of the tone arm.-

Having thus described the invention'what we claim is A talking machine sound conveyer comprising a sound box, a tone arm, a goose neck swln mg on said tone arm and communicating t erewith, and a tubular connection betweenthe sound box and the goose neck,

.said connection consisting of a horizontal portion, fitting said goose neck, thence extending downwardly, and thence extending upwardly and terminatin axially in alinement with the axis of said tone arm, with 20' HARRY HINKS-MAR'JIN'. ALEXANDER WILLIAM CAMERON. PEROIVAL JAMES PAOKMAN.
