OTTO KRAUS, OF NEW YORK, N. Y.

HORN-SUPPORT FOR TALKING-=WIACHINES.

Specification of Letters Patent.

Patented March 12, 1907.

iApplication filed July 18, 1906. $erial No. 326,703.

To all whorm it may concern:

Be it known that I, OTTO KRAUS, a citizen of the United States, and a resident of New York city, in the county of New York and d which can be easily and quickly attached to various sizes and styles of talkingmachines, is rigid, simple in construction, and will not mar or injure the usual highlyfinished surfaces of the talking-machines. The general practice in the construction of this class of talking-machines provides for a cover for the machine when not in use. This cover has on the lower edge of its sides two lugs, which fit into respective slots in the top of the box of the machine. These lugs after insertion in the slots fasten with a latch. Since the slots alone come into consideration with my horn-support, I will not further describe or show the cover and its fastening arrangement.

1n the accompanying drawings, in which like letters of reference indicate like parts in all the figures, Figure 1 is a side elevation of my new support attached to the box or" a talking-machine, showing diagrammaticallythe record-cylinder and the sound-box. Fig.

2 is a perspective view of the clamping parts of the device detached from the box or the Fig. 3 is a detailed side elevation of portions of the device in a folded position. Fig. 4 is a partial sectional side View of the height-adjusting device, showing the respec- Fig. 5 is a plan view of the above-mentioned parts with the adjusting-nut removed. Fig. 6 shows a modification of the clamping device with the supporting-bracket in section. Fig. 7 is a modification of the devices adapted to be attached to a box without protruding top Fig. 8 is a perspective view showing one of the slots through which the cover of thetalking-machine may be attached in the usual manner.

A represents the top portion of atalkingmachine to which the support is clamped.

L Bis one of the slots for fastening the cover and serves in this case to hold the angular pin O, fastened to rod E, Figs. 1 and 2.

D is a bracket made, preferably, of sheet metal and bent to form jaw-like portions d and 02, adapted to engage the protruding edge of the top portion A. The bends of bracket D are also disposed to form guides d for the rod E and to provide space for the knurled nut F. The guides d are located somewhat apart from each other, thus assuring proper alinement between the rod E and bracket D, yet allowing longitudinal adjustment of the rod E with the aid of the threaded portion e and the nut F. As clearly shown, one end of the piece of metal used in bending up the bracket D is provided with spurs d which are inserted in the upper part (i Fig. 2. The lower portion d somewhat apart from d is fastened to horizontal portion cl, with prongs (Z stamped out in close proximity to jaws cl and d. The space between parts (i and d is such as to allow turning of knurled nut F with ease. At the outer end of bracket D openings d are provided.

The pin O is made of round wire tightly driven into rod E and then flattened to correspond with the width of slot B. Since the size of the wire for pin O is larger than the width of the slot B, a shoulder is formed by the flattening process, which prevents the pin C from entering the slot beyond a predetermined depth. The pin O projects somewhat beyond the thickness of the top portion fl, so that its extreme lower end is entirely ree.

Loosely fitting .into opening d of the bracket D is the vertical rod G, held tightly by set-screw H. The lower end of the rod G is recessed and provided with a leather washer I to prevent any injury to table a. The upper portion of rod G is curved and is at its end provided with a pin g, with which a hinge-like ccnneclicn is formed with sleeve K, Figs. 3, 4, and 5. A portion of sleeve K, as clearly shown, is tightly secured to tube L, while the remaining pcrti n is open at the bottom to permit the swinging and folding of rod G, Fig. 3. The short slot is on top of sleeve K is adapted to cooperate with the screw M, which is securely fastened in red G. The screw ii is suflicientl lt ngto permit the folding of the rod without necessitating the entire removal of the knurled nut m. Se-

cured to the extreme end of tube L is the smazl collar R, with screw r to permit the adj ustment of the telescoping rod O.

The short chain'P, ending in a hook p, is adapted to engage a ring on horn Q, thus supporting same.

In attaching this novel support to a talking-machine the knurled nut F is turned until the distance between pin O and jaw d is sufficient to permit the insertion of the pin C into slot B, while aw (i is brought into engagement with the protruding edge of top portion A. When nut F is tightened, it is clearly seen that pin C on account of its angular position and its free lower end will be tightly anchored in the surrounding material of slot B, while jaw d is being held securely under edge of top portion A, Fig. 1. Through this action a firm contact is also being established between jaw d and top portion 62, thus holding bracket D securely in all directions.

In modification Fig. 6 the pin C is dis pensed with and instead the rod E made to extend over the entire width of top portion A with a hook-shaped end E engaging the opposite protruding edge.

In modification Big. 7 for boxes without protruding edge jaw d is made vertical and the lifting of the bracket D prevented by the extension of rod E with a collar E at its extreme left bearing on top portion A, cooperating with angular pin C.

After attaching bracket D in described manner the rod G is inserted in openings d and clamped in proper position by screw H. The rod G should alwa s rest with its lower end on the table upon which the talking-machine is seated when in service in order to avoid the danger of ti ting the machine when large and heavy horns are employed. The tube L is then swung into position to permit the entering of screw M into slot 7c and, as

clearly shown, may be held at any desired height by nut m.

I do not wish to be understood as limiting myself to the precise arrangement and construction of parts shown and described, but

reserve the right to all modifications within the scope of m invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
