Application filed July 6. 1903. Serial No. 164.276.

To all whom it may concern:

Be it known that 1, JOHN C. ENGLISH, a

of the city of Camden, State of New Jersey, have invented certain new and useful Improvements in Sound-Boxes for Talkin achines, of which the followingis a fuil, complete disclosure.

The object of my invention is to provide cooperating interlocking means for fastening sound boxes, which are used in connection with talking machines, to the sound tube or swinging arm thereof, in such a manner that the same may be quickly and securely locked together in position, and as readily unlocked, said means, in addition to performing the above functions, also forming a guide or stop for positioning the stylus bar with respect to the record so that the stylus, which is carried .thereby, may form the correetworking angle with the record.

Broadly, my invention consists in providing a joint connecting the sound box and the sound conveying tube with parts which easily interlock to prevent longitudinal separation of said members and at the same time form a stop .for limiting the rotary movement of the sound box'upon said tube and to determinethe angle of the stylus bar in relation to the record.

For a full, clear and exact descri tion of my invention reference may be ha to the f0 lowing specification and to the accompanying drawing forming a part thereof, in which Figure 1 is a plan view of the end of the sound conducting tube with the sound box in position thereon and showing a part of the sound box broken away; Fig. 2, a side elevation ofthesound box removed from the tube and showing the part thereof which engages said. tube; Fig. 3, a sectional view taken substantially on the line 33 of Fig. 1; and Fig. 4, an elevation of the sound box showing the outside thereof, or that opposite to the sound tube.

Referring to the drawing, the numeral 1 indicates a portion of the sound tube which 1s ointed at 2 to a semicircular curved porfrom said end. The sound box pro er 3 is made in theusual form but is provi ed with a short tube or collar 6 which has a pin or stud 7 projecting therefrom inwardly. Said collar is adapted to telesco e externally with the curved ortion 3 and t e pin 7 is adapted to engage t e L-shaped slot 4.

In plaein the sound box in osition upon the end of t 1e curved portion of the tubethe pin is made to pass into the slot longitudinally of the sound box or tube and then is turned transversely so as to enter the other portion of-the slot and so that said in will abut a ainstthe end of saidf'slot. 4 is so located upon the-end of the tube that when the pin is in the osition just described the stylus bar 8 will he (1 the stylus or needle in the correct position to produce the best results from the sound record.

It will thus be seen that my improved means for connecting the sound box with the sound tube not only provides a simple and position in relation to the sound record. his is particularly desirable in a talking are liable tobe assembled by persons who are not skilled in handling ap aratus and who are thereforecareless in ma 'ng correct adjustments.

Various changes may be made in the form and arrangement of parts herein set forth,

any preferred shape and may be located in either member of the joint and either part of said joint may be made to telesco e within the other and other changes may e made without departing from the spirit and scope of my inverition.

Having thus described my invention what I claim to be new and desire to protect by Letters Patent of the United States is 1. In a talking machine, the combination with a sound box, a support for said sound box and a stylus, of means for attaching said sound box to its support and for adjusting the stylus in operative position, comprising a bayonet joint, the members thereof being brought into 0 erative engagement by a movement of t at part of the sound box carrying the stylus relative to the support in thedirection in which pressure is brought upon the stylus when in operative position.

2. In a talking machine, the combination he slotfor instance, the transverse recess may be of efficient jointbut also provides means for holding the sound box in exactly the correct machine because of the fact that the parts with a sound box, .a support-[for said sound box and if stylus, of means for attaching said sound box to its support andfor'adjusting and holding the stylus in operative position,

and a =tue upon said support ada ted to entertlie'tube, on saidsbund box, t e tube on {said support bein'ggprovided with a slot to reo'eive saidlpin, 'sai pin being brought into engagement with 'the end ofsaid slot by a upon the stylus when in 'o erativ'e movement of thatpart ofthe sound box .carvryingthestylus,relative to the sup ort, in t e-;direc,tion in which pressure is rought osition.
