TALKING-MAORI E.

Specification of Letters iatent. Application filed April s, 1908, seriaincesaeee Patented Sept. 2 1909.

To all whom it may concern:

Be it known that I, HENRr F. Coorg a citizen of the United States, residing at Sag Harbor, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Talking-Machines, of which the followin is a full and clear specification, illustrate ing drawings.

-My invention relates to a means by which the movement of the stylus in spiral grooved records is stopped immediately aiter the stylus has left the record groove in order to avoid disagreeable sounds produced by the 5 stylus scratching on the record carrying body beyond the record groove.

In particular it relates to means which are controlled in their sto ping operation by the member or arm which carries the sound box.

I have also illustrated and described means by which the sound box with its arm may be quickly moved farther in the direction in which it has been moved over the record to o erate the stopping means.

' I have il ustrated my invention in the accompanying drawings of which-- Figure 1 is a plan view of a part'of a fiat record talking machine. Fig. 2 is a side ele '30 vation thereof seen in the direction of the arrow m Fig. 1.. Fig. 3 is a modification of the means for yieldingly moving ,the sound boxover the record. Fig. 4 is a side view of v the stopping device actlng upon the record tableafter the stylus has passed over the record, shown in enlarged scale. Fig. 5 is a horizontal larger scale. Fig. 6 is a. yertical section thereof on line X X in Fig. et.- Fig. 7 is a modification of spring 10 showni'n Fig. 2.

'- InFigs. 1 and 2, 1 is the iiop plate of the box containin the record ta well known in this art, 3 represents'the rec- 4 =5 0rd plate containing the spiral grooved rec- .ord it, 5 is the sound box liding, by means of the stylus 6, over the disk 3 in thespiral grooved record 4 in the Well known manner. The sound box 5 may be connected any to usual method to the horn 7, only art of which-is shown in Fig. through arm 8 Whichis ings as forming a part of the horn, which however,-may beeused only as a su porting member for the'sound box, as is w known in this type of machine, the horn being con- 2, as 'for, example I shall, therefore,

by the accompanylimits of t sectional view thereof, in still the mechanism for operating le 2 1n any suitablemanner shown in the draw-- independently of the sup I hereinafter refer to the member supporting the) sound box withdhe nected to the sound boxvby suitable tubing porting member 8.-

horn as arm or supporting arm. As shown" in Figs. 1 and 2 arm 8 isivoted in a bracket 9 fastened to the side 0? sound box and stylus in their travel over the record will travel in a circle around the pivot of bracket 9. The direction of travel box 1 so that the from the periphery of record disk 3 toward the center is indicated by the arrowin Fig. 1'. I have shown as an example means 0 1 moving the sound box over the record in the ently of the motion which the spiral groove in the same direction while the record disk 0 above mepltioned direction and beyond the e record which operate indepenobis revolving. To bracket 9, Fi 2, isfas'g.

teneda spring 10 in the form 0 a rod, one end of which is fixed to bracket 9, while the other end bears against the side of arr'n8 as shown in Figs. 1 and 2. The osition of this rod is adjusted so that it is cut out of its normal position by arm 8 when the sound f box is at or near the periphery of the record as shown in Fig. 1. Rod 10 will thus tend to move the sound box in the directiontoward the center of-thebisk as shown in this figure.

This tension maybe so adjusted that it will. 7

be just strong enough to keep the stylus in the middle of the record groove without imparting an undue thrust a ainst-either side. of the groove, and

.90 its yle ding may be in- "creased by offsetting it as shown in Flg. 7.

Instead of using a straight rod as shown in Fig. 2 a spiral spring may be used in the manner as shown for instance in Fig. 3. In the modification shown in this fi"u,re the is held at its end 12 by this bracket, while its other end 13 bears against arm -8 thereby.

tending to move the'latter in the same man'- ner as rod 10 described before.

In order to stop the machine as soon as the plug the record; plate or drum which devices,

however, are more .or less-complicated. The

novel stopping device I have shown in the;

spiral spring. 11 disposed on pivot l racket 9 I ammpanymg drawmgs in g s c has the 15 advantage of being siinple and easily attach- 'ableto any talkin machinewithout changing or otherwise isturbing' its mechanism.

The stopping device comprises a barrel 16 I end of 1c fastened rod 23 which prot 25' of lever 19 has an extension i 3 head 2 1, spring'29 will lever 19 into 35 arm 31 of lever 19 to 50 of record 5 provided at its protruding end with a head of suitable frictional'material 22, as for instance soft rubber or the like. Into the other plunger 18, which is disposed within barrel 16 is screwed or otherwise suitably through the closed rear end of barrel 16, and

' carries a head 24 at this protruding en Between-the rear endor bottom of barrel 16 and the plunger 18 is disposed a spring 1a 25 tending to force plunger 18 out of the barrel. On top of barrel 16 are provided two brackets 26 (Fig. 4), between which is oscillatingly' pivoted a lever 19 by means of pivot 20. The lower end 27 of lever 19 ro 20 trudesthrough an opening 28 provide in barrel. 16 and furthermore is adapted to be engaged, when forced through said opening by means of spring 29, by a notch or a groove 30 provided in plunger 18. The upper end arm 31, the end of which is formed into a nut in which stop screw 21 is disposed. If plunger 18 is retracted into barrel. 16, as shown in Fig. 5, by

pulling it back into the barrel by means of force the end 27 of oove :80 and thus lock plunger 18 in this position. Thus it will be seen that if lever end 27 is released from groove 30,

for instance by throwing" the upper extension the left (see arrow in {F 7 ,pf barrel .16 so far as the length of pin 23 .will allow. This whole stopping device is placed on and fastened to box 1 so that exytension arm 31 will protrude into the path of sound box carrying arm -8 which moves in the manner described above over the record. 1 The stopping device is further disposed so on box 1 that arm 8 will strike screw 21 of the stopping device soon after the sound box hasl'eft the record.

- It will now be seen that there being 'no 1 guide groove and very little resistance on the smooth, generally polished, surface 15 plate 3, the spiral formed by the stylus on this surface under the tension of spring 10 acting upon arm 8 will be of much greater pitch than that of the record groove;

n other words the arm willtend to move quicker towardthe center at the same revolution speed of the disk than it was moving when the stylus was guided by the recor groove. Upon engagement of screw 21 b arm 8 lever 31 Wlll be carried along wit the arm by the action of spring 10 and thereby release-plunger. 18 which was heretofore held in retracted position by the end 2( of lever 19. S ring 25 will throw the plunger- 18 out of barrel 16 and, the whole stopping device being disposed close enough rudes loosely spring 25 will force plunger 18 out to record table 2, head 22 of plunger 18 will bear against table 2 and thus stop the operation of the machine.

It frequentl occurs that it is desirable to use record dis (s on the talking machine of larger diameter than' the record table. In order that an unusually large record may not interfere with the structure of my stopping device, I have shaped bracket 17, by whic the stopping device is carried, ofi'set so that the maln body of the stopping device may be far enough ter of the record disk so as to clear the largest recorddisk which 'may be possibly used on this kind of machine. Plunger 18 is, therefore, of sufficient length so as to success; lly cooperate with record plate 2 ter of the 'dlsk as possible, I have ofiset arm 31 somewhat so as to counteract the offsetting of bracket 17.

In case it is not desired to have the table stop automatically by the inward movement of arm 8, I have pivoted extension arm 31 of lever 19 at 32, so that it may be thrown out of the ath of arm 8 by hand at'any time, and t e stopping device can then be thisfiind of ma chlne. ile I have shown in the referred in the specification an example of a stoppin member, I do not wish to limit myself to this particular kind, since the spirit of my invention involves a sto ping member independentpf the record table operating mechanism, sultably coiiperating with the table, which member is released to operate by a trip finger, coiiperating with any suitable element, following the movement of the sound box over the record, such as for example the arm 10 referred to in the specification. Moreover,'while I have shown my invention applied to a flat record talkin machine it is evident that the idea of yie dingly moving the stylus and its supl portingmeans in a record roove indepen ent of the motion imparte the record groove itself during the o eration of the machine but coiiperatingt erewith, ma be also applied to a cylindrical record ta king machine with ords without departing from my invention.
