PHONQGRAPH.

SPECIFICATION forming part of Letters Patent No. 470,477, dated March 8, 1892.

Application filed June 16, 1891. Serial No. 396,517- (No model.)

To all whom it may concern."

Be it known that we, FRANCIS M. CRISWELL, a citizen of the United States, residing at Washington, in the District of Columbia, an d JAMES A. E. CRISVVELL, a citizen of the United States, residing at Brooklymin the county of Kings and State of New York, have invented a certain .new and useful Improvement in Phonographs, of which the following is a full, clear, and exact description.

The object of our invention is to produce a continuously and automatically repeating phonograph. Incarrying out ourinvention we have constructed the record-cylinderwith mechanism whereby when it has made its full lateral travel it is returned automatically to the starting-point and its revolution and progressive lateral motion continued indefinitely in accordance with the length of run or motion of the motor.

We will describe the principle of our invention first and the best mode in which We have contemplated applying that principle and will then particularly point out and distinctly claim the part or improvement which we claim as our invention.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure l is a sectional elevation illustrating the application of our invention to the image of a crow. Fig. 2 is a front elevation, partly in section, of the phonograph; and Fig. 3 shows in perspective portions of the repeating mechanism. Fig. 4 is a sectional elevation similar to Fig. 2, showing our phonograph arranged to be worked by hand. Fig. 5 is a similar section showing our repeating mechanism applied to the Edison and kindred phonographs. Fig. 6 is a sectional elevation showing a modified form of our repeating mechanism; and Fig. 7 is a vertical cross-section taken, essentially, in the plane of line 00 w of Fig. 6, but showing the foot 121 to be in engagement with the latch 5.

One of the inventors of this invention has adopted for use in advertising his manufacpapier-rnach, or other material, and b is a perch or pedestal therefor. I11 the interior of the image of the crow is arranged the phonograph and a motor therefor, the latter in the illustration given being a clock-movement, although, obviously, other sources of power may be employed and located elsewhere than within the image.

In the phonograph c is the resonator, d the vibrating diaphragm chamber, and c the stylus.

ff are standards for supporting the diaphragm-chamber and other working parts of the phonograph.

g is the record cylinder or drum, and h the record-surface thereon. The record-cylinder is provided with a hub 'i, projecting laterally from one side, and this cylinder is fixed to a shaftj,which is adapted to slide in the direction of its length in bearings 76 and arranged in the standards f and f The bearing is is provided with a circular flange 10 which is fitted into a corresponding opening in the standard f and removably held therein on one side by screws 1: and on the other by the cylinderspring Z, which bears against it. The other bearing'k' may be fixed. The removable hearing admits of the ready removal of the cylinder, its shaft, and the spring. The hub iis provided with a screw-thread on its outer surface, and this screw-thread is engaged bya correspondingly screw-threaded foot m, which is I fixed in relation to the frame, so that as the cylinder is revolved the engagement of the screwthread of the foot with the screw-thread of thehub will cause such cylinder and its shaft to move laterally from the foot. This foot n, and the other end of this lever is engaged by a latch 19 atcertain periods, and this latch is held up to the lever by a spring q. Normally the latch and lever are disengaged.

The latch 13 is pivoted at its lower end to a post p on the standard f, and said latch terminates in a too or tappet 19 which extends therefrom in the direction of the length of the shaft j and toward the record-cylinder. A cam r is fixed to the shaftj next to the hub z and is adapted to engage and lift the foot m and the toe or tappet 19 as will be described. The lever 0 is provided with an arm 0 to lift the stylus e in the return movement of the record-cylinder.

In the accompanying illustration of our invention the phonograph-cylinderis arranged to be rotated by a clock-movement A, and for this purpose the shaft j is provided with a crank s on one end, and this crank engages a slotted pinion t, which is in train with the 3 main shaft to of the clock-movement. The

crank s is as long as the length of movement 1 of the shaft 7, so as always to be in engagement 3 A 1 ner, the record-cylinderis rotated, and as it rotates the foot m gives to it and its shaft a pro- The spring Z is gressively lateral movement. compressed during this movement until the cam 1" comes into contact with the foot m, at

which time the said foot is lifted by the cam out of-engagement with the screw-thread of the hub, when the spring is free to return the cylinder to its starting-point. By the lifting of the foot the arm 0 is also lifted, and it raises the stylus from the record-surface.

When the foot is lifted, of course the opposite end of its lever 0 is depressed, and when so depressed the spring 1 forces the latch into engagement with the lever and holds the foot up. The cylinder continues to rotate during this movement, and when the cam again comes Q uppermost it is in the plane of the toe or tappct 19 and, lifting such toe, rocks the latch and disengages the latch from the lever 0,

thereby permitting the spring m to throw threaded hub and removing the arm 0 from These operations are repeated so long as the power holds out, and hence a record on the cylinder may be repeated continuously without, as heretofore, renewing the power after each complete movement of the cylinder. is this automatic and continual repetition of the record which distinguishes our invention and which also renders our invention peculiarly adaptable for advertising purposes, although, it need scarcely be said, the same characteristic of our invent-ion fits it for more extended use.

The spring-foot and its lifting, latching, and releasing mechanism may be designated generally and for the purposes of this specification as an automatic clutch. Any clutching mechanism having the functions and mode of operation of these parts may be substituted for them, and hence we mean not to limit our broad invention to any mere details of construction.

The image of the crow will have a suitable opening-for example, a partilole billfor the emission of sound, and such image is constructed also withapartible or separable body for gaining access to the phonograph. The body of the image is made sufficientlystrong to receive the frames of the phonograph and its motor.

Instead of operating the phonograph by power we may mount the slotted disk tupon a shaft or arbor t in a bracket t and apply thereto a crank or clock-key or other turning.

device 15 as illustrated in Fig. 4.

Obviously our invention of repeating mechanism is applicable to the Edison and kindred phonographs, wherein the record cylinder slips on theshaft and the shaft has no sliding movement. (See Fig. v5.) In this case the cam r may be made upon the hub of the record-cylinder or upon a collar and fixed to the shaft, and the ordinary handle 8 may be substituted for crank s for operation by hand, or the shaft j may be geared for driving by power.

In Figs. 6 and 7 we have shown a modification of our repeating mechanism. The foot m is made as a lever pivoted at 2 to the standard f and normally borne into contact with the screw-threaded hub i by a spring 3, which is fastened to the standard f. The heel of the foot is made with a jog 4, which is engaged by the cam r to lift the said foot out of engagement with the threaded hub to permit the spring Z to return the record-cylinder. A latch 5, pivoted to the standard f, swings laterally of the foot m to engage a notch 6 in its rear end to hold up said foot until the record-cylinder returns. A spring 7, acting upon the latch 5, normally forces said latch toward the foot m. As the cam 7 comes uppermost when the latch is in engagement with the notch 6, it strikes the nose of said down the foot into engagement with the screwlatch and forces it out of said. notch, and

f thus the footis released to re-engage the engagement with the stylus, and thus permitting the phonograph to go 011 with its work. 1

The foot m in this IIO other forms'of phonographs, We do not limit our invention to the use of the peculiar form of shaft-bearings here shown, but may use other forms.

What we claim is 1. In a phonograph, a record-cylinder having a screw-threaded hub and usual means for receiving and transmitting a record, combined with means for rotating said cylinder continuously, a spring normally tending to return said cylinder, and a spring-foot screwthreaded to engage such hub, a lever to which the foot is jointed, a latch for periodically engaging such lever, and a cam for alternately lifting the foot and vibrating the latch for effecting the progressive movement of the cylinder to transmit its record and to return it automatically to the starting-point and repeat these operations, substantially as described. v

V 2. In a phonograph, a rotary record-cylinder and usual means for receiving and transmitting a record, said cylinder having a screwthreaded hub, combined with a complementally screw-threaded foot, a cam connected to move with the hub, and intermediate mechanism acted upon by the cam for effecting the engagement of the foot with said hub and to disengage and re-engage the two automatically during the rotation of the cylinder to effect repetition of the record continuously, substantially as described.

" 3. In a phonograph, a rotary record-cylinder, a shaft to which it is fixed, hearings in which said shaft has longitudinal motion, and

usual means for receiving and transmitting a 7 record, said cylinder having a screw-threaded hub, combined with a complementally screwthreaded foot, a spring to hold it in engagement with the hub, a lever from one end of which the foot is suspended, a latch to engage the other end of such lever, a spring normally tending to return the cylinder, and a cam to disengage the footand hub and cause the engagement of the latch and lever and thereafter when the cylinder is returned to release the latch and lever and permit the foot to engage the hub, substantially asdescribed.
