corresponding points around the periphery of the casing,\the ange I4 is cut to form slots 28 which receive screws 30, the latter being threaded into flange 20 and tabs 26. The screws 30 thus hold the parts I8 and 22 in fixed relation, and also hold these parts in adjustable relation to the outermost member I4.

The diaphragm D is preferably made of paper or light parchment, and given a conical shape such as has been highly developed for use in radio loud speakers. The edge portion 32 of the diaphragm is secured to the casing within the face portion I2. The diaphragm is preferably corrugated, as shown at 34, to increase the nexibility of the same. The -center 36 of the diaphragm is connected to a light stylus arm 38. 'I'he stylus arm is pivotally mounted near the casing wall. In the present case a thin leaf spring 40 is clamped at one end between the parts 38 and 42 of the complete stylus arm, and is clamped at its other end between blocks 44 and 46 iixedly mounted on the casing wall. The stylus S is carried directly in the collar 42 of the stylus arm, and extends toward and directly engages the record R. The stylus is, of course, located directly in the single sound groove 48 (see Fig. 8) of the, record. The contact pressure between the stylus and the record is xed when the phonograph is initially assembled, this being made possible by reason of the screw and slot construction 30, 28 heretofore referred to. The blocks 44, 46 supporting the stylus arm are preferably themselves mounted'on a block 50 of rubber which is independently secured to the casing wall. Such an intermediate cushion relieves the stylus of excessive pressure, should the initial adjustment be faulty or the record be out of true. I have, however, obtained satisfactory results even with a rigid mounting directly upon the casing wall devoid of any form of intermediate cushion. I

'I'he record R is here illustrated as a disc record having a lateral sound groove. The record is substantial in diameter, it having a diameter nearly equal to that of the casing, which, of course, is desirable in order to obtain substantial sound reproduction while using only a single sound groove. 'Ihe record is backed up by a recordV support plate or table 52, and the record and table are clamped to a record shaft 54 by means of a washer 56 and nut 58 which clamp the record and record support against a collar 60 formed on the record shaft 54. Record shaft 54 is rotatably supported in bearings formed at the center of the plates I8 and 22 of the casing.

The governor G comprises relatively large iiat weight arms 62 and 64, best shown in Fig. 3, which are respectively pivotally mounted at 66 and 68 on the record support 52. Weight arm 64 carries a brake shoe I2 adapted to ride directly on the inner cylindrical wall of ange 24 of the casing. The weight arms 62 and 64 are interconnected by a link `'I4 freely pivoted on the collar 60 of the record shaft. Link 14 insures simultaneous opposite movement of the weight arms, so that the eect of both weight arms is applied to the brake shoe 12. It is preferred to use two or more Weight arms in symmetrical arrangement in order to balance the governor mechanism. I nd it better to use a single brake shoe on one of two interconnected arms, than to use separate brake shoes on two independently movable arms.

Much of the simplification of this governor arises from its being mounted directly on the record support. and this in turn is made possible because of the large dimension of the governor tviileights and the large radius at which they func- The mechanism so far described is common to the phonographs of Figs. 6 and 7 as well as Fig. l, for these species diifer only in the drive mechanism of the phonograph. Referring first to Figs. 1 through 5, I illustrate drive mechanism actuated by a pull cord 80. This pull cord is -connected at 82 to a drum 84 about which it is wound. Drum 84 is mounted and freely rotatable on record shaft 54. A spiral take-up spring 86 is connected to the casing at 88 and to the drum at 90. The drum carries a stop arm 92, while the casing is provided with a stop 04 cooperating therewith, this stop being struck outwardly from partition plate 22. It Will be evident that by pulling cord 80, the drum 84 may be rotated for a single revolution in one direction, and that upon release o1' cord 80, the drum is rotated in opposite direction by spring 86. In the present case it is preferred to drive the phonograph while pulling the cord, so that the spring 86 may be light and inexpensive. It is possible, however, to reverse this arrangement and to use a heavy spring which itself drives the phonograph, the cord then serving merely to rewind the spring.

Rotation of the drum 84 is imparted to record shaft 54 through clutch means operating to drive the record in only one direction. For this purpose the record shaft 54 is provided with an arm 96 forcibly driven on the record shaft, and drum 84 is provided with a triangular projection or driving pawl 98. Upon rotation of the drum in one direction, the arm 96 is driven therewith by projection 98, but upon reverse rotation of the drum the arm 96 remains stationary. To prevent the possibility of reverse movement of arm 96, particularly at the end of the return movement of the drum when the sloping side of projection 98 reaches and bears against the arm 96, the phonograph is preferably provided with stop mechanism here exemplified by the triangularlyshaped stop I 00 struck outwardly from partition 22 and best shown in Fig. 5. Arm 96 is readily moved past stop I00 in the forward direction but not in the reverse direction.

For successful operation of the mechanism thus far described, it is highly desirable that drum 84 go through a complete revolution which must not'be diminished by even the amount of the Width of a stop arm such as the stop arm 92. In fact, for safety the drum 84 may be allowed to rotate a slight amount more than a revolution. Forthis purpose the stop 94 heretofore referred to is stepped to form a part 94 spaced from the part 94 by an amount equal to or greater than the width of the stop 92, this being best shown in Fig. 4. The part interconnecting the stops 94 and 94' is located in alignment with the stop arm 92 and provides a sloping or rounded approach for the stop arm. Consequently, when stop arm 92 moves in one direction, it is brushed slightly sidewardly until itreaches the stop 94, whereas when it moves in opposite direction it is brushed slightly sidewardly on the other side of the connecting portion 95 until it reaches the stop 94. In this way thedrurnl may be given one complete or even slightly more than one complete revolution.

A modified form of drive mechanism is shown in Fig. 6. In this case the phonograph is actuated by a push rod |02 extending out of the casing and carrying a push knob |04. The rod |02 is a rack meshing with a pinion |06 which is freely rotatable on record shaft 54 and which replaces the drum 84 heretofore described. The pinion |06 carries a disc |08 having a triangular driving pawl ||0 cooperating with the arm 96 of the record shaft. The rack |02 is guided by an extension ||2 passing through the opposite side of the casing. A compression spring ||4 around rod ||2 acts to restore the rack to initial position. 'I'he rotation of pinion |06 depends upon the gear ratio between the rack and pinion, and may be adjusted to permit only a single revolution. However, if desired the pinion may be made smaller and the parts arranged for a multiple of one revolution, say two revolutions, in which case the record is played twice for each operation of the push rod.

In Fig. '7 I show an even simpler form in which the record shaft 54 h-as a crank |20 mounted directly thereon. The record may be played'repeatedly by simply turning the crank. To prevent reverse rotation of the record, the shaft 54 is provided with a slip spring |22 having one end anchored on the casing at |24 and being wound about the shaft in such direction that it is loosened when the record is turned in proper direction, but is tightened and locked if attempt is made to turn the record in reverse direction.'

It will be appreciated that if desired the crank |20 may be free from the record shaft and coupled thereto by an appropriate clutch transmitting rotation in only a single direction. In such case the crank may be turned backwardly but without causing rotation of the record.

In Figs. 9 and 10, I illustrate a modified form of phonograph which differs most importantly in the mounting or suspension of the stylus. It is desirable to make possible the manufacture of these articles at very low cost and manufacturing tolerances must therefore be large. Furthermore, the record may not run true on the shaft. It is therefore desirable that the stylus S be so supported as to be yieldable both radially and axially of the record without however interfering with successful sound reproduction.

In the arrangement of Figs. 9 and l0, these'results are obtained by attaching the stylus supporting spring |40 (corresponding to spring 40 in Fig. 1) to a support ring |42 which extends around the speaker diaphragm D. Ring |42 is provided with a plurality of hooks |44 in which are caught loops |46 of a continuous rubber band |48. Band |46 extends around the exterior of the cas'ing C and the loops |46 are drawn into the casing through holes |50. To prevent creeping of the band and consequent change in adiustment or location of the stylus, the band may be locked in place by a strip of paper |52 cemented around the band and the exterior of the casing.

The casing is, in this instance, provided with a separate end cap |54 on which the elastic band is mounted. To facilitate assembly of the casing, the cylindrical part |56 thereof is slotted at |56 in registration with the perforations |50 and the loops |46.

In order to increase the compactness of the entire phonograph unit, diaphragm D is reversely dished at the central portion |60, thereby making possible the interposition of an elastic strut or pin |62 between diaphragm D and the stylus arm |38. 'I'his construction accommodates the rather free oating of the stylus mounting in operation.

The drive mechanism of the phonograph here illustrated corresponds to that shown in Figs. 1 through 5 of the drawing, but the speed control mechanism has been simplified by elimination of the governor. Instead, a disk of felt or equivalent material |64 is placed between the record R (or the record support if the record is separate from the record support) and the intermediate or partition platew |66 in the casing. 'I'he record shaft is so dimensioned and mounted as to create frictional resistance to rotation by the felt, and inasmuch as the record only rotates a single revolution, I nd it possible to obtain adequate speed regulation by this simple means. 'I'he felt disk construction is, of course, much more inexpensive than a true governor mechanism.

It is believed that the mode of constructing and using, as well as the many advantages of my improved miniature phonograph, willbe apparent from the foregoing detailed description thereof.

The mechanism is simple, inexpensive, light in weight, and compact. The sound reproduction obtained is loud and clear although of short duration. The mechanism is devoid of means to lift and reset the stylus, and instead the stylus is permanently fixed in engagement with the sound groove of the record. The record may be played in any position. 'Ihe sound box mechanism is simplified and lightened by the use of a large diaphragm mounted across the open end of the casing. No horn or equivalent amplifying chamber is employed. The device may be used as an advertising novelty to repeat the name of a product I or an advertising slogan. It may also be used as a voice for a doll.

It will be apparent that while I have shown and described my invention in preferred forms, many changes and modifications may be made in the structures disclosed, without departing from the spirit of the invention, defined in the following claims.
