LOUIS P. VALIQUET, OF NEW YORK, N. Y.

AUTOMATIC GRAMOPHONE.

SPECIFICATION forming part of Letters Patent no. 631,912, dated August 29, 1899. Application filed April 6, 1899. Serial No. 711,899 (No model.)

To aZZ whom it may concern:

Be it known that I, LOUIS P. VALIQUET, a citizen of the United States of America, and a resident of New York city, New York county,

for automatically operating what is known asthe gramophone.

-My invention has many of the features of construction and principles of operation described in my application, Serial No. 694,824, filed October 28, 1898, but is designedto be thrown into operation by means other than coin-operated mechanism.

The preferred form of apparatus embodying my invention is illustrated in the accompanying five sheets of drawings, in which- Figure 1 is a plan view of the apparatus with the top of the case containing the same removed and a portion of the needle-carrying arm broken away. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is a section on lines 3 3 of Fig. 1, showing the needle-carrying arm in its initial position and the mechanism at rest. Fig. 4 is a similar section show ing the gramophone in operation, the parts being in the position occupied by them just before the return mechanism is tripped into operation. Fig. 5 shows a modified form of brake-lever. Fig. 6 is a diagrammatic detail showing the retaining device just after it has been tripped and the return mechanism released and starting into operation to return the needle-carrying arm to'the initial posi-- tion shown in Fig/3. Fig. 7 shows a modification in which the winding up of the motor sets and trips the mechanism.

Throughout the drawings like referencefigures refer to like parts.

I have shown the gramophone and attached mechanism in a casing 1, having a hinged cover 2, attached to the casing by the hinges 3 3 at one end. A sliding or'other form of movable cover might of course be employed.

The gramophone has the ordinary form of base 4, containing rotating mechanism, (not shown,) on which the rotating table 5 is mounted. A spring-motor of any desirable form (not shown) is located in the addition 6 of said gramophone-base. This motor is wound up by means of bevel-gears 7, a shaft 8, and winding-handle 9, the latter being outside of the casing 1. .On the rotating table is the ordinary grarnophone-record 10, clamped thereon by a thumb-screw 5 in the usual manner, so as to rotate therewith. On this record rests the reproducing-needle 12 of the sound-box 11, carried by the swinging arm 13, said arm being mounted by a universal joint 14 on the pivot-bracket 15, fastened to the gramophone-base, all in the usual and well-known manner, when the machine is in operation and reproducing sounds from the record.

16 is a piece of tubing of rubber or other flexible material extending from the soundbox 11 to the elbow-shaped tube 17,which extends through the cover of the surrounding casing and to which an ordinary horn may be connected.

The pusher 19 is normally held back by the spring 28 or equivalent elastic device. This pusher is preferably connected to the lever by means of the pin-and-slot connection 24. This lever 25 is pivotedon the bearings 27 in the bottom of the case 1 and so controlled by the spring 28 that its upper hook-shaped end 25 is against the swinging arm 13 and under the same when the said arm is in its initial position against thestop 31. The pivoted catch 29, mounted on the stop 31 by the pivotal joint and controlled by the back spring 32, overhangs and engages with the swinging arm 13 when the latter is supported in its initial position by the springcontrolled hook-shaped lever 25 in the manner above described.

The lever 25 engages with a horizontallyswinging brake-lever 37, pivoted on the end of the bracket 15 and carrying the brake-shoe 38, which engages the rotating table 5. when the spring-controlled lever 25 is in the position shown in Fig. 3 to hold up the needlecarrying arm 13. This engagement is preferably secured by passing the lever 25 through a slot 42 in the said brake-lever.

A modified construction is shown in Fig. 5, in which the brake-lever 37 is removed, and a lever 37 a is pivoted on the gramophone-base,

one end of the lever carrying the brake-shoe 38, While the other end is struck by the spring-controlled lever 25 (upon its return) to apply the brake. In this case the guide 39 is also dispensed with. The spring-controlled lever 25 operates exactly as in the other construction. Instead of carrying the lever 37, however, with it in its movementit merely strikes the end of the lever 37, when it returns the swinging needle-carrying arm to its original position, and thereby forces on the brake 38. Of course when the swinging lever 25 isforced out from under the needlecarrying arm it leaves the end of the brakelever 37, and all pressure is removed from the brake-shoe 38, so that the machine is free to operate.

34 is a retaining'device in the formof a dog pivoted at 36 and having a nose 35 arranged to slide over and grasp the brakelever 37, thereby retaining the same and the lever 25 in a position out from under the needle-carrying arm.

is an adjustable screw mounted in the tail of the dog 34 and located in the line of travel of the needle-carrying arm 13, as the same is fed along by the sound-record'during the operation of the machine.

41 is a spring tending to hold the dog 34 down in engagement with the brake-

lever

37, and 40 is a lug on the dog 34, projectingdown in the path of the brake-lever 37 and so located with reference to the pivot 36 of said dog that when the brake-lever strikes the lug it positively pulls the nose of the dog 35 down behind the brake-lever, lh us assisting the action of the spring 41.

39 is a guide for the brake-lever.

The operation of my invention is as follows: The cover 2 of the casing being closed and the parts of the mechanism being in the position shown in Figs. 1 and 3, the operator first winds upthe spring-motor by means of the handle 9 and then forces in the pusher 19, which forces the spring-controlled lever 25 to the right, Figs. 3 and 4. As the springcontrolled lever 25 goes over it carries with it the brake-lever 37, until the latter has passed under the nose 35 on the retainingdog. 34, which immediately slips down behind said brake-lever. When the operator removes pressure from the pusher 19, the spring 28 forces the lever 25 back against the nose 35 of the dog 34, which holds it in the position shown in Fig. 4. When the hook-shaped supporting end 25 is forced over to the right, as above described, the swinging arm 13 is prevented from traveling with it by the pivoted spring-catch 29. When the hook-shaped lever has passed out from under the swinging arm, the latter is free to drop down and the reproducing-needle 12 engages with the record 10. The brake-shoe 38 having been with drawn from the rotating table 5' by the first motion of the lever 25, said table and record carried thereby are already in rotation by the time the reproducing-needlo comes down on the record and the gramophone begins to 0perate, reproducing sound, which is delivered through the tube '17. As the needle and sound-box are fed across the record by the action of the same in the well-known way the swinging, arm 13 travels toward the adjustable screw 33, mounted in the tail of the dog 34. Said screw is so adjusted that the arm will strike it when the needle has reached the end of the record. A slight further movement of the swinging arm depresses the rear portion of the dog 34 against the'spring 41 and lifts thenose 35 of the dog 34 from behind the brake-lever 37, as shown in Fig. 6. The spring 28 immediately acts to force said lever 25 back into the positionshown in Fig. 3. On the way the hook-shapedend 25 picks up the needle-arm 13 and carries it back under the spring-catch 29 and holds it there in its initial position ready for a repetition of the operation. The same movement of the lever 25 has forced the brake -shoe 38 up against the rotating table 5 and stops the rotation of the same. It has also forced'out the pusher 19, ready for another operation. It is evident that if the pusher 19 be forced in rapidly, so that under ordinary circumstances the brake-lever 37 might be forced back again by the spring 28 before the retaining device could recover from the shock and the violent throwing up of the nose 35 of the dog and could respond under the action of the spring 41 to seize and retain said brakelever, the very factof the rapid movement of the parts thus described will carry the brake lever beyond its normal travel up against the lug 40 and so positively pull the dog 34 down into operative position and insure the retention of said brake-lever and connected parts in the position shown in Fig. 4, until tripped by the needle-carrying arm at the end of a complete operation of the gramophone.

-It is evident, of course, that many different agencies for setting the apparatus might be substituted for the manually-operated pusher 19. -One' such I have shown in Fig. 7. The shaft 8 is extended, and a friction-wheel 18 runs under the friction-plate 20. This plate is mounted on a vertical shaft 21, which carries the drum 22. On this drum winds the cord 23, which passes around the spring-controlled pulley 26 and the fast pulley 26 to the lever 25. When the motor in compartment 6 is wound up, the shaft 21 is revolved and cord 23 Wound up The spring-controlled pulley is in the full-lined position. The winding therefore pulls lever 25 over to the position shown in Fig. 4, and the machine is ready to operate. Further winding does not break the cord 23, because Lthe friction-wheel 18 slips under the plate 20. When the operator stops winding, the gramophone begins to opcrate. The cord 23 is unwound from drum 22, the slack being taken up by spring-pulley 26, which moves into dotted-line posi- When the lever 25 is tripped. at the tion.

with the winding necessary to run the shortest record the cord 23 will be taken up the amount needed to carry the lever 25 over to catch under the dog 34. WVhen winding for longer records, the slip in the friction connection allows for excess motion. The springcontrolling pulley 26 must of course be a weak one, just strong enough to take up the cord.

The advantages of my invention result from the certainty of operation under all conditions, from the simplicity and cheapness of the apparatus employed,and from the rapidity of the return-feed action, which is practically instantaneous. It is also extremely convenicnt of manipulation, as by throwing up the pivoted catch 29 into the position shown in dotted lines in Fig. 4 the needle-carrying arm can be lifted out of engagement with the hook 25 and swung to one side for changing the records, putting in anew needle, and making other adjustments.

It is evident that various changes could be made in the details of the apparatus described without departing from the spirit and scope of my invention so long as the general relative arrangement of parts shown in the drawings or the general principle of operation set forth in the specification is preserved. \Veights might be substituted for springs, and other forms of moving parts might be substituted for the levers. Other agencies might operate the lever 25, other frictioncouplings be used, &c. but all these variations I consider within the general scope of my invention.

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