PHONOGRAPH.

To'aZZ whom it may concern:

Be it known that I, HARRY L. .CAssaRn, a

citizen of -'the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Phonographs, of which the, following is a specification.

My invention is designed to provide a talking machine or sound producing device of the kind known as phonographs, graphophones and gramophones.

' It relates more particularly to the gramophone type in which a disk record is .employed. My idea, is to provide a cheap toy of this kind for reproducing articulate spe'ech, muslc, songs, &c., in WlllCh, instead of a definitely driven motor" mechanism, the device is to be held inthe hand and the necessary movement for causing-the traverse of the needle in the groove of the record is secured by a whirling action in the hand, one of the 'parts being eccentrically weighted to cause, by centrifugal action, a' movement between the needle and the record. U. S.

Patent No. 836,470 was granted to E. C. Smith for a device of this generalcharac ter. My invention is designed to be an improvement upon this device, which permits of the use of cheap ten cent records and secures a muchclearer and louder tone and at a less expense, as will be more fully de scribed hereafter with reference to the drawing, in which:

Figure 1 is a perspective view of the complete device. Fig. 1 is a sectional end view of the open end of the sound box. Fig. 2 is an enlarged under side view of the sliding bottom of the sound box and itsattachments. Fig. 3 is a view of the blank from which the needle holder frame is fashioned. Fig. 4 is a view of the needle'holder, and Figs. 5 to 8 are views showing modifications.

In theidrawing, Fig. 1, A is a resonant box preferably square in cross section and of elongated form and open at one end. The

bottom B of the box slides longitudinally,

in guideways at the lower longitudinal edges of the box. 1

D is an ordinary disk record of gramophone type which is clamped rigidly to a basic table T on handle C in right angular position.

position and having a small enlargement or flange Z) which clampsthe disk to the end of the handle when the screw stemis turned in and which permitsthe quick and easy substitution of new disk records. A wooden block or hub (it embraces the axial stem E within the, box and is rigidly connected to' the stem by a setscrevv just beneath the top of the box so as to hold the box a predetermined distance above the disk record. On the lower side of the sliding bottom B of the box is rigidly mounted a light diaphragm F of the. same general form and structure as the lldof a pill box made of any vibrating material, paper or cardboard serving the purpose for cheap construction.

to hold the shank of the needle and which needle holder is clamped to the frame by a set-screw and is made to pinch and hold rigidly the needle. The horizontal mem ber of the needle holding frame has at its outer end a spur s which rests against the diaphragm through the intermediary of a For the cheap and convenient formation of this needle frame it is stamped in one'piece of thin metal in the form of the blank shown in'Fig. 8, the lug Z of the blank in Fig. 3 forming, when bent around, theneedle. holder H of Figs.

2 and 4.

Referringnow to Fig. 1, it will be seen that the sound box A turns freely on the stem E as an axis and the needle rests in the spiral groove of the record D, the center of gravity of the box being on one side of the axial stem, so that When the handle C isgrasped in thehand'and a whirling or gyratory motion is given to the box the latter swings around the axial stemE and the needle traverses the groove in the non rotating disk and thus the record of the disk is reproducedby the vibrant quality of the diaphragm and sound box, Which latter acts like a violin body to greatly amplify and clarify the sound, Whether it be articulate speech or music.

I In carrying out my invention Itmake various modificatlon of the same. Thus. for m- 25 also givesa diverging horn-like outlet for stance instead of making the whole bottom of the box slidable, the box may be made in two telescopic or collapsible sections as in Fig.

5, one section being hung on the axial stem and the other being arranged to carry the needle and. capable of progressive motionin radial direction to the central axis as theneedle traverses the groove of the record. Furthermore, the sound box may be constructed as n F 1g. 6, in which the box is I closed on all sides .and has slotted holes like. the f-holes of. a violin, to let the sound out. In this case the needle w is attached 2 to a button 1 and this, see Fig. 6f, is connected by two rubber covered pins 2 to a slide 6 inside the box. The rubber covered .pins aslide in a slot u' in the box toward or away from the axial center "v.' In Fig. 5 one side of the movable-box section forms the diaphragm and in Figs. 6 and 6 the button 3 and attached slide t form the diaphragm.

Anbthen modification, seen in' Fig. 7, shows the sound box in triangular or Wedge shape. This not only makes the outer end heavier for-better centrifugal effect, but

the sound, the box'being open at its'larger both supported -uponand carried by the relation thereto.

an eccentric -w'i ht. r and fswivelin it on the axial stem, and clamping the sound box.

in such case rigidly to the handle by nuts nn.

In all of these formsthe resonant sound box, of Violin action, is, employed and the sound box is provided wlthjtwoparts capable of relativeprogresslve movement toward or away from the center in radial direction to permit the proper traverse or progression of the needle in the groove of the disk record, the needle I and diaphragm being sound box but being sli dably adjustable in WhatIclaim is: Y 1.

5. In a sound producing device of ,the kind described, the combination with a disk record member and a manually operable.
