ATTACHMENT FOR TALKING-MACHINES.

Application filed April 12, 1913.

To all whom it may concern Be it known that I, Eown: S. ANTISDALE,

a citizen ofthe United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Attachments for Talking-lVIachines, of. which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The invention relates to attachments for talking machines and seeks to provide simple and effective means for automatically lifting the sound box and stopping the turn table when the reproduction of the record on the turn-table is completed.

Another object of the invention is to provide such an attachment which can be readily applied to talking machines now in use.

The invention consists in the features of improvement hereinafter set forth, illustrated in the preferred form in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of the upper parts of a talking machine with the improved attachment applied thereto. Fig. 1 is a detail section on lines (La of Fig. 1. Figs. 2, 3 and 1 are front, side and rear elevations, respectively, of the improved attachment, In Fig. 3 the actuating weights are shownin section. Fig. 5 is a side elevation of a modified form. Figs. 6 and? are vertical sections on the lines 6-6 and 7-7 of Fig. 5. I

The turn-table 1 of the talking machine is arranged above a horizontal top board or plate 2 and is rotatably sustained by a center shaft 3 which is operated in the usual manner by a suitable motor. A sound box a having a stylus 5 is arranged to move over a record 6 on the turn-table. The sound boX is carried upon a shittable sound box arm 7 which is swiveled at its rear end in a suit able bearing 8 to swing in a horizontal plane. The sound box is movable vertically to and from therecord 6 and, for this purpose, in the' form shown, it is mounted upon a Lf-sha'ped tube 7 which'is horizontally "swiveled to the outer end of the sound-box arm 7.

A brake is provided for arresting the Specification of Letters Eatent.

movement of the sound box. Inthe form shown, the brake comprises a plunger 9 which is slidably mounted within a bracket 10 fastened to the top plate 2. A spring 11 is arranged Within the cavity of the bracket 10 and is coiled above the lunger 9. Th1s' spr1ng is adapted to PIOJQClI the plunger into engagement with the edge of the turn-table A brake controlling device or lever 12 pivoted on the casing 10, s provided with a cam shoulder 13 which is arranged to engage a pin 14 connected to the brake plunger to thereby hold the brake in released position against the tension of.

the spring. The parts thus far described are of any usual or suitable construction.

The improved attachment for automatically lifting the sound box and setting the brake when the reproductionof the record is completed, comprises a support movable over the face of the top 2 to and from the sound box arm, so that it can be adjustably positioned upon the top in accordance with the length of the record to be reproduced. A latch mounted on the support is arranged to be engaged and tripped by the sound box arm 7, and means on the support and con trolled by the latch are arranged to lift the sound boX and operate the brake controlled device or lever.

The support for the automatic attachment preferably comprises a haseweight 15 which is preferably formed of lead. An upright frame or casing is mounted upon the base weight 15 and, in the forms shown in Figs. 1 to 4-, inclusive, comprises front and side walls 16 and 17 and a top wall 18. These walls, in the form shown, are made of sheet metal and are suitably secured together and to the base'lfi. A vertical guide rod 19is fixed atits lower end to the base15 and at its upper end to the top wall 18.

A pair of actuating members or weights :20 and 21 are slidably mounted upon a rod 19; The lower weight 20 is preferably heavier than the upper weight 21 and is connected to the end of acord 22. This cord 2:? extends upwardly through an open- .55 sidewall 17 and the end of the latch is arrangedto be engaged b the sound box arm extends to the sound box 1 and isfastened to a scr w26 threaded in an opening in the jfixed tothe base 15. The end of th e cord2'7 is connected tothe brake controlling device-or lever 12,- 1

21 are controlledby a common latch 36. In

the form shown, the latch is made of sheet metal-and is of inverted U-shape inoutline and is provided with two depending legs or members 31 and 32. This latch is disposed against the inner face of the side wall 16 of .th'eupright frame and is connected thereto terline of the-latch 30, so that-the latter is held in normal position by gravity with the edge of the leg or member 32 abutting against the .side wall 17 of the upright frameQThe.lowermbst weight is provided with a laterally projecting .pin -34 which projects outwardly through a vertical slot' 35 formed ,inthe front wall 16. The leg or member 31 of the latch is provided at its upper end with a shoulder 36 which. is arranged to engage the pin 3% and hold the actuating member-or weight 20 in the elevated position shown in Figs. 2, 3 and 4. Inasmuchas the actuating weight or member 21 is arranged above the weight 20, it

is also held in raised position by the common latch. The lower portion of the leg or member 31 of the latch is provided with a curved edge which is arranged to be engaged y the pin 34 to swing the latch to one sid as the weights 20 and 21 are raised. In setting the device, the weights are raised bv hand and at the end of the upward movenient of the weights, the latch swings by' gravity to the position shown in the drawings, and the shoulder 36 thereon engages thei'pin '34: to hold the actuating members or.weights raised or'iin set position.

The other leg or member 32 of the latchis provided at its lower end with a laterally projectinglug :37 which extends outwardly through an opening. 38v (see Fig. 3) 1n the The upright' franle of the support is preferably provided with a projecting guide lug 39 which is adapted to be engaged by the 7 sound box arm 7 is positioning the attach ment. The lug 37 is arranged adjacent and projects slightly beyond the g'ilide lug 39.

The pivot pin is'arranged at one side-of the cenarm 'until the stylus 5 of the sound box is at the end of the sound groove of the record.

The sound box arm is then swung Laway from the support, the weights or actuating.

members 20 and 21 are raised and are held in raised position by the latch 30, the brake plunger 9 is released by means of the con-- trolling lever 12 and the sound box is placed 7 in position with its stylus 5 at the beginning of thesound grpoye'of the record. At the s end of the reproduction of the record, the

sound box arni7, as-indicated in dotted lines in Fig. 1, engages the project-inglug 37 of the latch'and shifts it so that-the shoulder i 0 36 thereof is disengaged from the pin 34.

The weights or actuating- members 20 and 21 then fall. medium of the cord 22, aptomatically raises thesound box from the record, and the weight 21, through the medium of the cord 27, shifts the brake controlling device or eration to stop the turn-table by means of its spring 11.

v lever 12 so thatthe, brake is thrown into op-v in position to arrest the movement of the weight 20.

It should be noted that separate actuating members are provided forilifting the sound box and actuating the brake controllingdevice or lever 12." This is of importance,

since in this way the throw of the weight g 20, which raises and lowers the sound box, can' be uniform. The attachment, however,

must be adjusted to and from the sound box in accordance with the length of the record and, therefore, the distancebetu-ecn it and the brake, in the construction shown, necessarily varies. I 21is separate from and above the weight-20, its downward movement, necessary to shift the lever 12, can also vary.

But'inasmuch as the weight of the reproduction of the record.

icence The device 18 simple in construction, can

be readily applied to talking machines now in use, can be readily adjusted and operates effectively and automatically to lift the sound box and stop the turn-table at the end It is obvious that numerous changes may be made in the details set forth- For; example, spring shifted, actuating members may be employed instead of weights. In

theform shown in Figs. 5, l3 and 7, the base 42 carries two tubular uprights 43. These uprights are connected at their lower ends by a cross bar 4% and at their upper ends by a cross piece A side wall or plate i6 is fixed at its upper and lower ends to the cross pieces 45 and ll, respectively. A pair of actuating members or plungers L7 and 48 are. arranged Within the tubes 5% and springs 49 Within the tubes extend between the plungers and plugs 50 fixed in theupper ends of the tubes. Y

The plungers 47 and 18 are provided with laterally projecting pins 51 which extend through slots 52 in the tubes l3 and are connected, respectively, to the ends of the cords '53. and' 54. The cord 58 extends upwardly over a guide roller 55 at the upper end of the supporting frame and, like the cord 22 in the form shown in Figs. 1 to s, inclusive, is connected to the sound box. The cord 54 extends upwardl overa guide roller 56 at the upper end of the frame or casing and thence downwhrdly over a guide roller 57 and, like the cord 27, is connected.

to the brake controlling device or lever of the machine. 1h the construction shown, the guide roller 57 is mounted in a bracket 58 which is swiveled or pivotally connected by a screw 59 to the upper face of the base 42. A cross head 60 is slidably mounted upon the upright tubes l3 and is rigidly connected to the plunger a? by the pinfol projecting from this plunger. The pin5l connected to the plunger 48 extends above the upper edge of the cross head 60 and,

when the cross head is raised, the plunger 48 is necessarily raised W1 th it. The parts,

. however, can move downwardly independentlyof each other and to different extents.

On its rear face the cross head 60 is provided with a hook or dog 61 which is arranged to engage the hooked lower end of a latch 62. This latch is in the form at a leaf spring and'i-s riveted at uper end to the upper portion of the plate 46. The latch is provided With'a depending portion 63 Which extends outwardly through a slot in the plate 46. The lower end of the projection is arranged to be engaged by the sound box arm to shift the latch and release the cross head and actuating members or -plungers l7 and 4.8. The plate is-provided .Wltll a rearivardly pro ecting guide lug which, like the guide lug 39 Oi'bud form previously described, is arranged to be engaged b the sound loox arm in positioning or setting the automatic attachment upon the top plate, of the talking machine. In this form, a rod 65 projects rearwardly from the base 42 and has an eye 66 at its rear end which engages a pivot pin 67. The pin 3? is mounted on a plate 68 that iS fastened to the top 2 of the machine and a nut 65) on the pin engages the eye 66. The plate GGmay be arranged adjacent the bearing of the sound box arm so that the attachment, as l1, is usted to and from the sound box, will always be maintained in such position that the arm will properly engage the lug 63. The operation of. this form is similar to that previously described. Doubtless other changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims,
