SPECIFICATION forming part of Letters Patent No. 776,672, dated December 6, 1904:.

7 Application filed July 21, 1904. Serial No. 217,491. (No model.)

To all whom it may concern:

Be it known that I, .HARRY B. MCNULTY, a

, citizen of the United States, residing at W ashington city, in the District of Columbia, have invented certain new and useful improvements in conical double-jointed arms for talking-machines, designed to carry the soundboX at its extreme end, incidentally for the support of said arm and horn and also a double sound-box; and I do 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 ap iiertains to make and; use the same, reference being had to the ac companying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

This invention relates to new and useful improvements in the detail construction of that part of a talking-machine that is known as a conical doublejointed arm, designed to carry the sound-box at its extreme end, incidentally for the support of said arm and horn.

The object of the invention is to provide an improved sound-box connection and support of such a design and construction that it shall be free to accommodate itself to records of different thicknesses and breadths as well as to the unevennesses in the record itself.

More especially, the invention provides means whereby the sound-box-carrying arm and support will be vertically and horizontally adjustable at will to any make of machine and is, furthermore, to provide a con duit and connections for the same from the sound-box to the horn of such a construction and combination of parts that the volume of sound delivered from a given record shall be clear and distinct and at the same time obviates certain elements which have heretofore been objectionable and, moreover, ,to con struct the details of the invention in such wise as to direct the sound straight to the ear instead of over the head.

Also the invention consists in an especiallydesigned joint between the conical arm and the elbow-coupling, thereby obviating the rattle that has been noted in other devices of this character, as herewith claimed.

A still further object of the invention is to provide a device of this character which may be assembled or disassembled at will without the use of tools.

This invention comprises, further, the various modifications, details of construction, adaptation, and novel combination of features, which will be hereinafter more fully described and then specifically defined in the appended claims.

The invention is illustrated by the accompanying drawings, which, with the characters of reference marked thereon, form a part of this application, such characters of reference indicating like parts in the views.

Figs. 15

and 15 are views of the form shown in Fig.

14:, showing the manner of assembling and disassembling; Fig. 16, a view of a modified form of coupling between the sound-box and joint at the end of the conical arm; Fig. 17 a top plan view of Fig. 16; Fig. 18, a detail perspective view of a modified form of the pivotal cone-bearing for the rear portion of the conical arm; Fig. 19, a detail view showing the manner of disassembling and assembling the parts of the form shown in Fig. 18; Fig. 20, a sectional view on line 20 20 of Fig. 18.

Referring to and designating the different parts and modifications of the accompanying drawings by letters and numerals, (4 indicates an ordinary talking-machine which has secured thereto a plate 6, said plate Z) being made integral or detachable, preferably integral, with the rod 0, of cylindrical character, which is provided on its underneath side with a rectangular slotway (Z, adapted to receive the tightening-screw e and the guide-stud f, carried by the cylindrical bearing g of the armsugport h, which is slidably mounted upon the r0 0.

Made integral with the top of the arm-support it is a collar k, which has an inner hearing Z, adapted to receive the flange m, which is made integral with the elbow-coupling n.

Projecting from said flange m is a projection p, which is utilized in locking the elbow n in such a manner as to allow for free movement after attaching the elbow-coupling-that is to say, when it is necessary to register the projection p with the cut-away portion g, similar in shape, you then insert the said coupling a and give a partial turn until it is in locked position, as illustrated in the drawings.

Spanning the opening in the collar 71: is a bar 7*, having a cone-bearing .9, adapted to receive a small cone-shaped projection 25, which projects from a bar it, said bar 20 being made integral with the upper part of the right-angled turn of the conical arm a).

w designates a chamber, being closed at one end and open at the other, as at 3 y, and also provided with a cut-away portion a in slot form, said chamber being made integral with the conical arm c. Mounted to have a loose movement in the chamber w is a ring-band I), having brazed or soldered across the diameter of the same the hollow shank portion of another elbow-coupling, 0', adapted to be connected to the sound-box, said sound-box cZ being provided with an abutment-lug e to engage a similar lug f on the elbow-coupling c for the purpose of erecting the soundbox in correct position to act upon the record. For the purpose of closing the chamber to after the ring-band has been inserted I provide a cap 9', having threads to engage threads 71 upon the chamber to. To allow for adjustment and swinging movement, I provide the rear convexed portion of the conical arm with a hollow extension is, designed for the purpose of receiving the pin 6, which is provided with a spiral cam-thread m. Mounted in the wall of said extension 7c and adapted to engage with the spiral cam-thread is a thumb-screw n to limit the said adjustment. There are two cam-slots provided upon the inside of the enlarged ends of the elbow-coupling for the purpose of engagement with the lugs q, mounted upon the tapered end of the horn. To secure box up out of engagement with the record, I provide means consisting of a spring-catch r, riveted to the chamber w, said catch being provided with a lug 8, designed for engagement with a notch 6 upon the ring-band b. Thumb-screws u are used to securely attach the plate Z) to the side of the talking-machine (0. Figs. 7 and 21 illustrate a slight modification of the adjustment of the conical arm, whereby the rear convex portions of the said arm are provided with a cone-shaped stud 1, designed to have a bearing in the head of an adjusting thumbscrew 2. Figs. 18, 19, and 20 also illustrate a slight modification of the pivotal conical arm. In this case the cone-shaped stud 1 is designed to have a bearing in the top of a screw-threaded stud 3, made integral with the arm-support it, said stud 3hav'ing a V-shaped way 1. Mounted to have a vertical movement in said way 4 is a V-shaped slide 5, which has provided on its outer face a projection 6, designed to have play in the circumferential groove 7, provided in the inner threaded portion of the nut 8. It will be readily understood how the arm a; is disassembled from position by the construction shown in Figs. 18, 19, and 20.

In Figs. 14, 15, and 15 I have shown a modification of the joint 9, whereby the elbow-coupling 0 is detachable, as at 10, from the ringbearing 6. Also both ends of the chamber 20 are opened, as at 11, adapted to be closed by two caps g instead of one. In Figs. 16 and 17 the coupling 0' is shown as being straight, as at 12, and the sound-box shown at right angles to that shown in other figures of the drawmgs.

Figs. 7, 7 and 7 c show a modification of the connection between the elbow m and the collar 76, thereby obviating both the projection 19 and the cut-away portion Q and substituting in lieu thereof a bevel 13 upon the lower face of the flange mof the elbow-coupling. In connecting the coupling 01 it is necessary to make a scooping movement to bring the upper edge of the flange m under the slight extension 1 1, made integral upon the collar In.

In Fig. 11 the joint 9 is located at the rear portion of the arm 1), as at 15, the said armo having a turn at 16 and provided with a slot 17 to receive the shank portion of a screw 18, the said screw being provided for the purpose of keeping the arm a from being detached, but at the same time allow the said arm a) to have a quarter-turn when it is necessary to raise the sound-box from the record.

In Figs. 12 and 13 the coupling a has two cam-threads 19 performing the same function as the slots Of course it is understood that various changes can be made in the details of construction and combination of parts other than that illustrated in the accompanying drawings without in any way departing from the spirit and scope of the invention.
