WILLIAM s. wear, or eHAnLorrEsvILLn, VIRGINIA.
'sror Eon TALKING-MACHINES.
misses.
' State of Virginia, have invented anew and.
useful Stop for Talking-Machines; and I do hereby declare the following to be a full,
clear, and exact description of the invention, such as will enable others-skilled in the art to which it appertains to make and use the same.
This invention relates to the art of talking machines, and more especially to an improved stop and starting mechanism, automatically actuated by the tone or sound arm, for automatically stopping and starting the record supporting turn table.
It is known that owing to pieces, songs and the like varying in length, records of talking machines correspondingly vary. In other words, as is termed in the commercial field, there are what are known as deep and shallow records. Therefore, it is an object of the present invention to provide a stop and starter, which may be adjusted according to the record, in order to be vautomatically actuated by the tone or sound arm, at the beginning and the termination of the record.
Another object of the invention is to pro' vide a stop and starter mechanism of this kind comprising simple, improved, eflicient and practical features of construction.
One of the features of construction is the provision of a brake lever including a brake to frictionallv engage the peripheral edge of the turn table of the talking machine for arresting the table in its movement, in combination with a pair'of levers, to which link members are connected, one linkbeing slidably connected to the other link, and adapted to be actuated by a member on the tone or sound arm to actuate the brake lever, in order to remove the brake shoe from the table, the other lever to which one of the links is connected is actuated by a springto hold the brake shoe out of engagement with the table.
Another feature of the invention is the provision of adjustable means upon one end of the other means, designed to be actuated by the member on the tone or sound arm, to
actuate the lever which is holding the brake lever, to release the brake lever and allow its shoe to again engage the table.
Another obJeet of the invention is to con- Specification of Letters Patent.
Application filed April 14, 1916. Serial No..91,081.
Patented Feb. 13, ieit.
struct means carried by one of the links to be engaged by the member on the tone arm ;as it reaches the limit of its inward movement with novel features of construction, whereby said means may be adjusted, to stop the machine, relative to the extent of movement of the tone arm, whereby the brake lever will operate with promptness and with precision.
In practical fields the details of construction may necessitate alterations, falling within the scope of What is claimedi The invention comprises further features and combination of parts,- as hereinafter set forth, shown inthe drawings and claimed.
In the drawings: a .Figure 1 is a plan View of a portion of a talkingmachine, showing the automatic stop and starting" mechanism as applied,
whereby the mechanism may be operated automatically by the tone or sound arm.
Fig. 2 is a perspective view of the stop and starting mechanism detached.
Fig. 3 is a plan view of the stop and starting mechanism, showing the casing for the brake lever in section and showing the means-to be actuated by a member on the tone arm at the beginning and ending of the movement of the tone arm broken, and
the part broken away disposed below.
Fig. 4 is a view partly in plan elevation and partly in section, and illustrating parts broken, one part above the other, so that the various elements of the mechanism may be illustrated one large scale.
Fig. 5 is a sectional view on line 5-5 of Fig. 3, looking toward the casing, in which the brake lever is arranged. 'Fig. 6is a sectional view of the member to be carried by the tone or sound arm for actuating-the stop and starting mechanism.
Referring more especially to the drawing, 1 designates a portion of the casing of a talking machine, and in which casing the motor for driving the record supporting turn table 2 is designed to be arranged.
The tone-or sound arm 3 is mounted upon the casing 1 pivotally as at 4, whereby the arm may swivel or move pivotally in a lateral direction, so that the stylus or needle of the reproducer or sound box 5 may follow the record groove from its beginning to its termination near the center of the disk. A plate 6 is secured to the casing 1 by means of suitable s'lgjews 7.. Pivoted peripheral edge of the turn table 2.
. and one end of the slot 36 ofthe enlarge-' ment, the tendency of the spring 39 being to throw the rod in the direction of the by means of a screw8 to the plate 6 is a brake lever 9, one arm 10 of which is provided with a dove-tailed recess 11, to re: ceive and hold a suitable brake shoe 12, which maybe constructed from any suitable material, rubber, felt or the like, and designed to frictionally engage the peripheral edge 13 of the record supporting turn table, to hold the table at rest. The brake lever 9, has connected. to its other ,arm 14 a suitable coil spring 15, which is in turn connected to the stud16, the spring 15 actuating and holding the brake lever, so that the brake shoe 12 frictionally engages the peripheral edge of the table. The brake lever 9 has an enlarged segmental portion 17, which is provided with the shoulders 18 and 19. livoted on a screw 20 of the plate 6 is a dog 21, the nose 22 of which is designed to engage the shoulder 19, when the dog 21 is rocked upon its pivot, so as to oscillate the brake lever-9, to throw the brake shoe 12 out of engagement with tllp detent lever 23 is pivoted upon the screw 24 of the plate 6, and the arm 25 of said detent lever is provided with an angled end 26, to engage the shoulder 18, to hold the, brake lever when thrown to the position shown in Fig. 4, with the brake shoe 12 out of engagement with the peripheral edge 13 of the turn table. One end of :1 coil spring 27 is connected to a stud pin 28, and has its other end connected to'a pin 29 of the detent lever 23, so as to hold the angled end 26 of the detent lever 23 in engagement with the shoulder 18. A link 30 has one end pivotally connected by means of a pin 31 to the arm 32 of the detent lever 23. This link is provided with a slot 33, which is constructed substantially midway the center of the link 30. The end portion 34 of the link 30 has an enlargement 35, which is provided'with an elongated slot '36, which is in a transverse plane at right angles to the slot 33. A rod 37 is adjustably mounted in she opening 38-of the ends of the enlargement 35, there being a coil spring-39 in the slot 36 and surrounding the rod 37, and interposed between the transverse pin 40 arrow a. However, pivotallymounted upon tween the offset bent end 45 and one end of the enlargement, thereby acting to hold the angled end 43 "in engagement with the circumference of the rod 37, to hold the rod .37 .in different adjusted positions against the action of the spring 39. A link 46 is pivoted by means, of a pin 47 to one end tion, there being a suitable band of felt or p the like 56 between the clamp and the arm, so as to prevent scratching or injuring the tone arm. The member or section 53 of the clamp has a downwardly protruding extension 57 provided with a threaded bore 58, into which the shank 59 of a T-shaped pin 60 is threaded, there being a suitable lock nut 61 for holding the T-sha-ped pin in adjusted position in the threaded bore. The reduced part 62 of the shank of the T-shaped pin engages theelongated-,slot 33 of the link 30, while the head of the T-shaped pin engages the under face of a the link 30 adjacent the slot 33. The plate 6 is provided with a suitable inclosureor casing, that fits downwardly uponthe same to protect the various elements carried upon said plate. When the talking machine is at rest the brake lever 9 is in the position shown in Figs. 1 and 3, so that the brake shoe'engages the peripheral edge 13 of the turn table. After a record is placed upon the turn table, the tone or sound arm.- is
moved in the direction of the arrow 6 in Fig. 1, until the reduced part 62 of the T-shaped pin 60 engages the crotch 48 of the link 46, and by further movement of the pin 60 the dog 21 is tilted upon its pivot in the direction of the arrow 0,. thereby causing the nose .22 to rock the brake lever upon its pivot against the action of the spr ng 15, so that the angled end 26 will engage the shoulder 18, thereby holding the brake lever in the position shown in Fig. .4,
the result of which permits the turii table to rotate, and the record therewith. When the stylus-of the sound "box or reproducer.
reaches the end of the sound groove, the rod 37 having been. adjusted accordingly,
the reduced part 62 of the "T-shaped pin.
60 will contact with the end 65 of the rod 37,.thereby pulling upon the link 30, which will rock the detent lever 23 in the direction of the arrow 03, thereby disengagingthe angled end 26 of the detent lever from the shoulder 18, thereby allowing the brake shoe to engage the periphery. 13 of the turn table to stop the machine.
