Specification of Letters Patent.

Patented March 13, 1908.

Application filed February 12,1993. Serial he. 143,060.

To on! whom it maiy concern:

Be it known that I, Ew nnor: It. Johnson, oi'the city of Philadelphia, State of Pennsylveniii, have invented certain new and useful 5 Improvements in 'lalking-Mnchincs, of which the following is a full, clear, and complete dis closure. 1

In a talkiiw-mnchine where an amplifying horn is elnplizyed for delivering the repro dueed sounds it is desirable and advantagoousin ohtainin the highest degree of efliciency in the-qua ity and volume of the tone reproduced to employ not onlv a large horn, but also to locate the smell end of the horn as near as possible to the sound-box ,or reproducin mechanism. By locating the small end the horn in this manner so that the s0undeonducting tube or horn flares outwardly )raotioally from the sound-box l have iound that it allows the sound-waves to advanee with areguiar, steady, and natural increase in their wave fronts in a manner some-- what similar to that of the ordinary musical instruments, thus obviating the well-known disadvantages due to long passages of smell and practically constant diameter. it is also desirable to avoid abrupt turns in the soundconducting tube or passage.

It is therefore the ob'eet of m T invention to provide a talking-machine wit an amplify mg-horn meeting these requirements and at the some timeto reduce the size, length, and Wei ht of the horn, so that it can be convenientily transported.

in the specification in connection with t are ac.- companving dra'win s, forming :1 art thereof, which show a pro erred form 0 apparatus embodying my invention.

In said drawings, Figure 1 is a side elevation of in improved construction as applied to the tallr-ingnnachine; Fig. 2, a horizontal sectional View of the smal end or hollow arm portion of the amplifying-horn, showing the 5 means to allow'of the vertical movement of the sound-box; Fig.3, a vertical seetional View showin the means whereh the larger portion of t e horn is. adjustah y mounted and the hollow arm or lower portion of the a horn is pivoted so {is to communicate there- ,wjth; '4, a len view of the end of the till) ort or the erger portion of the ampli- 'jqzhorn Fig. 5,11 View of the yoke for holdillgt e same in position upon its support,'nnd

()ther objects of my invention will a peer Fig. 6 e plan view of the end oi the hollow arm or pivoted portion of the amplifying horn.

The nniuerul 1 indicates thr usual motoreusing, ulmve which revolves the usual turntable 2 and upon which is carried the soundreeord 3. At one sidrof the casing 1 a bracket or arm 4 is provided which is. similar in shapeto those :rlreudy in use excepting its upper end portion. This upper om. portion 5 corn sists 'ol" 3, ring ('3, hiring a bar 7 across one dienicter thereof. The bell portion 9 of am plil'yi'ng-horn is, provided at its end. with u flange 9, which is adapted to be seated upon the ring 6 of the support 4. The up )er end of the support 5 is provided with a flat portion 8, having a. screwholo 30 therein Upon this flat portion a yoke i0 is udu'ated to be fixed I) the tlmmlrsrrew ii. The arms of this yolic 1.0 project over the ring i and are adapted to press upon the flange 9 of the bell portion of the innpliiying-horn, and thereby retain said portion in position. It will be no ticed that this construction enables the hell portion of the horn to he directed at any angle horizontally to send the sound to any point which choice or convenience may require. The arms of the yoke 10 are slightly curved and are made of s ring material, so that the bell portion of the 1011'! may be easily placed in iosition and removed.

' Upon t e arm 4 a boss or projection 12 is presided which is recessed internally to provideiesocket for a heerin I -hloei 13, which is forced upwardly by a. eoi ed spring 14. The horizontally-pivoted hollow arm portion 29 of the amplifying-horn is curved upwardly and termintes in a. ring 15, having s ider-erm 16 across two diameters thereof. lpon the elbow or curve of the horizontally-pivoted arm of the horn is provided a. boss 17, having a hole 18 therein which corresponds with a hole 19 in the spider at the end of said curved passes through these holes or openings and is retained in position by the set-screw 21. The lower end of this pivot-bar 20 has a bearing in the sprin .-pressed block 13, and its 1.1 per end enters t e bearing 22 in the bar 7 0 the support 4. The parts are of such a size and oted arm of the horn will enter the ring 6 for a short distance; bot suflicientfiipaee is left between said narts to allow saidv arm to swing are so adjustedthat the upper end of the piv- .portion. A vertical pivot pin or bar 20 freely and yet to provide a practically soundtight joint.

The ioint for allowing a vertical movement to the sound-box is constructed as'follows: The inner or smaller end of the horizontall ivotedhollow-arrn portion 29 of the amp iying-horn is provided with a strap or ring 23, which is adapted to receive and form a bearing or socket for the end of a semicircular'piece of tubing 24. The end of this piece of tubing 24 is held in position by suitable flan e 25 and by a cap 26, which also serves to c ose the outer end thereof. To the other end of the curved tubing 24,:is attached a plate 27, which carries the usual sound-box 28. It will be seen*that by this construction the sound-box is brought ractically into alinement with the end of the horizontallyivoted hollow-arm ortion of the horn, and- 1s therefore on a re. us from the axis of the pivot-bar 20. i

From the foregoing desoriptionit is seen in the first lace that I provide, in effect, an am plify'ing orn that extends practically from,

the sound-boxaud that it consists of two sw tions, one of'which isthe tapering hollow' sound-conductin arm -pprmanentl'y mounted upon the mac 'ne, W 'le the other section is removable horn-pro er. The advantage ofthis is,tl1at I secure t e-reguisite length of {constantly flaring or tapering horn, which less, cumbersome to carry. ,The other advahtageisthat the-weight imposed upon the stylus arid the, record isfreatly reduced,- since' the thorn is supporte entirely by the bracket 4 while it retains all the advantages inthat it scapahle'of being turned in any direction independent of the sound-tube 29, and this sohnd-tube 29 is supported so that it is capable orily ofa movement parallel with the face citthe record, being free to swing horizontal ,andqrnconstr'ained and ours strained w i swinging in this direction except by the UoJiera-tive contact of the stylus in thesound- 'ioves of the record-tablet, and the horizont l movement of this sound-tube ,29 is, also substantially uninfiuenced by its own weight and that of the sound-box carried thereby, and it is'further to be noted that I have avoided to the greatest degree any ab- 1 rupt turns, while thesound-box is movable towardand awag' P i, I 'misi'mmei hfllpcally in its movement to 7 from the record indently ofi' e soun tube 29 and. is uncon ward and away from the record, resting by its own Wei ht when reproducinig andbein capable of being lifted and move and turns on its pivotal support to an inoperative posi tion, resting upon said sound-tube 29. In fact, I have produced, in efiect,a sectional horn tapering from end to end, the large section of which is movable independently of the smaller section, whichlatter isca able of inovin only in a plane parallel'v'vit the recordta let and by means ofthe operative contact I thus sc-- of the st [us in the recordroove. cure all t e advantages of t e large size remov able born with the further advantage that the horn is materiall reduced in size and weight, and I secure the 'rther advantage due to the use of a hollow arm, which moves only in a plane tactically parallel with the face of the recor ahdpporiitheE-nd of .which is carried fime greatly reduce the length of homflirol i -g om the bracket or arm 4.

In emplo I I allel' and horizontal it will be understood that such terms are used to express the enng in the claims the terms "pareral relation of the parts referred to aud t eir movement and relationin a general we and when such cparts are used in their or inary manner an although theoretical] perha s.

there might not be always 'a strict ypara el or horizontal relation or condition it-woilld be so to all intents and purposes.

of the horn also provides a rm support therefor and are placed at a point in the horn where the same is not so small as to require special means for strengthening its supporting ,ortion. v

C anges indetails may be made without departing from the spirit and scope of my mvention; but,
