Patented June 23, 1942 UNITED STATES "PA' I ENT OFFICE rnouoc iz DEVICE I I I Ladle H. Ottofy, Chicago, 11!. I 7 Application December 30, 1939, Serial No. 311,711- 1 4 Claims. ((1274-41) the card or sounding diaphragm in such relation This invention relates in general to a manually operated sound producing device for reproducing various sounds such as words, music, phrases, and

the like, and has more particular reference to the provision of an inexpensive, simplified structure which is economical to manufacture, easyto assemble and operate, and not likely to get out of order.

An important object of the invention is in the provision of improved means for guiding a sound record strip to insure the proper contact of the sound producing portion of .the strip with an amplifier ordiaphragm to whichit is applied.

' to be held in the hand. This card may be printed- 'A further object of the invention is in the provision of a sound producing device consisting of a card or cardboard adapted to be held in one hand by engaging the edges of the card and a sound producing stripv adapted to be inserted through the card and in contact therewith to be grasped by the other hand so that the maximum vibratory or sound producing effect will be ob tained.

Other andfurther objects of the invention will appear hereinafter, the accompanying drawing illustrating the preferred structure and modifications thereof, in which Fig. 1 is a face view of a phonographic device in accordance with this invention;

Fig. 2 is a side elevation partly in section showing a phonographic strip as applied to a car;

Fig. '3 is an enlarged view showing the engagement'of the sound producing strip; and

Figs. 4, 5 and 6 illustrate modifications in which the sound producing strip is inserted through a diaphragm in contact with a sounding member and under a staple or through the diaphragm to insure contact with the sounding member.

In the operation of sound producingdevices of the talking card type in which an advertisement, greeting or other subject matter is applied to a display card or cardboard in which the phonographic strip is movable, the contact of, the sound producing side of the strip with theedge of the or decorated in any suitable manner, preferably as a birthday, Christmas, or a greeting card, or it may be for any other use such as an advertisement, and a message, word, or other sound relating to the printed matter on the cardor independent thereof, may be provided on the phonographic strip 9 which preferably has one smooth side l0 and a phonographic side I I, although both sides of the strip may be provided with a phonographic message if desired.

In the card shown by Figs. 1 and 2, perforations l2 and iii are spaced apart on the card and are of sufficient size so that the strip 9 may be inserted freely therethrough, preferably from the back through the upper opening, forming a loop on the face by inserting it through'the lower ,opening. In order to distinguish the starting and finishing ends of the strip, the starting end It is sharpened and the finishing end I5 is rounded.

Ordinary cardboard will soon become worn by the engagement of the roughened side of the phonographic strip which usually is of harder material than that of the card and if thus rounded and worn it does not transmit the vibrations or sound from the strip with sufficient cleamess.

A staple I6 is applied to the card at the edge of the opening 12, the ends 'of the staple being card causes it to wear away and unless the card is made of material substantially as stiff or rigid as the material of the strip itself, the sound produced will not be clear and distinct. It is furthermore desirable in order to produce a clear and distinct sound that the phonographic side of the strip shall be maintained in close contact and engagement with a sounding device of harder material at all times in producing the sound.

The present in'vention obtains the desirable results by producing a sound producing member in the form of a staple which is firmly ailixedto fastened through the card upon the rear or reverse side thereof in such a location that when the phonographic strip is inserted through the perforations of the card to form a loop at one side thereof the sound producing side of the strip will bear against the edge of the staple l6, thereby causing it to act as a bearing or sound producing member and communicating the vibrations imparted to it by the movement of the sound producing tape to the card itself. The card being held at its edges will vibrate at its central portion where the sound producing mem her is located and thus will produce the sound in accordance with the vibration produced by pull ing the sound-producing strip through the card. It is understood that the sound producing strip may be of considerable length compared with the-card so that when the pointed end It is in-v serted through the perforations l2 and i3 sumciently to provide a hand grasping portion, the remainder of the strip which has not been pulled through the opening I! will contain the message so that by pulling the strip in one direction-the predetermined sound is produced by the diaphragm. To repeat the sound the tape may be 'pulled reversely through the card, giving of! a jumbled or undistinguishable noise, and the strip under a staple 22 which projects from the face of the card, the result being that thestrip when pulled through the opening is held downwardly on its sound-producing side against the staple 20 byjreason 01' its engagement under the other staple 22.

. As shown in Fig. 5 the tape passes between two sounding staples 25 and 28 extending across an opening 21 or having an opening in the card ting member extending across the openingand secured to the diaphragm, a sound record strip to extend through the opening having a record sound track at one side thereof engaging the member, and the diaphragm being formed with means at a distance from the opening for confining the intermediate portion of the strip in contact with the diaphragm and insuring that the sound track side 0! the strip is held in contact with the vibration transmitting member when the strip and diaphragm are relatively moved.

2. In a phonographic device, a sound record strip having a recorded sound track at one side thereof, a sheet sounding diaphragm provided and formed with an opening through which the strip is inserted, and with means spaced from the opening for coni'lning an intermediate portion of the strip therebetween with the sound track facing the diaphragm centrally thereof, and a vibration transmitting member at the edge '01 the opening engaged'by the sound track side of the strip when moved through. the opening to- I ward said means, and the opposite side of the strip being drawn againstsaid-means when the strip is moved in the intended so'und producing direction.

between'the staples through which the strip is inserted and the forward or advance end of the strip may be inserted through another opening 28 or under a staple 22 as shown in Fig. 4.

3. In a phonographic device, a sound record strip having agrecorded sound track at one side thereof, a sheetsounding diaphragm having an opening through which the strip is inserted and a vibration transmitting member at the edge of the opening, a'staple extending from the diaphragm at a distance from the opening for con- It is also contemplated 'that'a fastening clip 30 having spring extremities 3! inside 01' a teetangular portion 32 havi an end bar 33 may be applied over the edge of a card so that the end bar 33 is located over an opening II through which a sound-producing strip may be'inscrt'ed to engage the bar-and then extending in a loop fi blmh an opening 38 or under a staple as shown Fig 4.

v In all of these ram. it will be apparent that a loop isproduced at one side oi the card which insures that the, sound-producing side of the tape. will be held in close contact or engasement with the sound-producing member or staple, thus causing the sound-producing vibrations to be imparted to the card so that the card will give oi! the maximum and most distinct reproduction or sound caused by the strip. I claim:

1. In a phonographic device, a sheet sounding diaphragm having an opening therethrough at a distance from the edges, a vibration transmitdining an intermediate portion of the strip-between the staple and-the opening with the sound track engaging the vibration transmitting member at the edge of the opening when the strip is' moved through the opening and under the staple, and the opposite side of the strip being drawn against the inner side or the staple when the strip is moved in the intended sound produc- I in: direction.

4. In a phonographic device, a sound record strip having a recorded sound track at one side thereof, a sheet sounding diaphragm formed with ber toinsure that the sound track side of the an opening through which the strip is inserted, a vibration transmitting member at the edge of the opening, another opening spaced from the first opening through which thestrip is also inserted for confining an intermediate portion of the strip between the openings with the sound track engaging the vibration transmitting memstrip will-engage the vibration transmitting member when it is drawn through the openings in the intended sound producing direction.
