TALKING-MACHINE.

Specication of Letters Patent.

Patented Apr. 30, 1918.

Application led September 8, 1917. Serial No. 190,287.

Y o all ywhom it 'may concern:

Be it known that I, FRANCESCO CIRELLI, n subject of the King of Italy, residing at Philadelphia, in the countyof Philadelphia and Stute of Pennsylvania, have invented certain new und useful Improvements in Tnlkin rMachines, of which the following is a s ecihcation. i

ne object of my invention is to provide improved sound transmitting apparatus for t-.ilking machines which renders it unnecessery to employe horn or cabinet construction such as hes been the custom to employ prior to my invention.

Another object is to so construct my imroved sound transmitting apparatus that 1t can be used in various positions and places such for example as on an ordinary table or board and can be moved bodily `independently of the record support. A further object is to so constructmy invention that it will be of simple construction, durable and can be manufactured and sold at o. reasonably low cost.

These objects, end other advantageous ends which will be described hereinafter, I attain in the following manner, reference bein had to the accompanying drawings in" whic Figure 1 is a side elevation of my invention shown in operative engagement with but mounted independently of uy motor driven record.

Fig. 2' is a. view of similar nature to Fig. 1 but showing my invention out of engagement with the record.

Fig. 3 is an enlarged section on the line 3 3 of Fig. 1 showing the upper portion v of the horn in outside view.

Fig. 4 is en enlarged sectional plan taken on the line 4 4 0f Fig. 1.

Fig. 5 is an enlarged fragmentary section taken on the line 5-5 of Fig. 4 showing a. portion of the tone arm in outside view.

Referring to the drawings, 1 represents a. table or support which ma. be of any construction upon which is p aced a motor 2 for rotating a disk record 3. A cylindrical tray 4 of metal, hard rubber, or other sultable material, is adapted to rest upon e supporting structure such for example es the table 1.

A cylindrical ou 5, preferably of metal, rotatablyts within the trey 4 and hes a closed bottom 6. The tray 4 can be secured to the table or other support 1 by a. screw 7 or if it is desired, this tray may be free to be moved on the table at the will of the operator by omitting the screw.

The cup 5 hns standards 8 which project upwardly at different points throughout its circumference and thereby provides o enings 10 as clearly illustrated. A ring or end 11 is supported on the tops of the standards 8, and this ring. serves to strengthen the standards by connecting them together.

Two of the standards 8 which are diametricully opposite euch other have extensions 12. These extensions have holes 13 in which ere placed rubber or other non-metallic bushings 14 which have intel-nul Henges 15. Adjusting screws 16 pass `through the bushings 14 and have heads 17 whereby they may be manually actuated. These screws 16 form e swinging support for up-turned iianges 18|a on the bottom of a. tone arm 18, the opposite end of which supports the sound box 19 having a. needle 20 for engagement with the record 3.

The bottom -edge 21 of the tone arm 18 is positioned et n higher level than the ed e 9 of the cup 5, so that the openings 10 w1 1 form outlets for the sound reproduced from the record through the medium of the needle 20, sound box 19 and tone erm 18, alfter the sound has been transmitted. into the cup 5 it being noted that the closed bottom 6 ii the cup 5 serves as a stop for the sound as it passes out of the tone arm in the directions of the arrows es illustrated and causes the sound be deiiected u Wardly und out of seid openings 10 w ere it is distinctly audible.

i The journal screws 16 permit the tone arm l to rock 1n e vertical plane as illustrated, and the cu 5 is freely rotatable within the tray 4 so tiiat the tone arm 18 is free to move in any direction required during the reproduction 4of the record.

A journal sleeve 22 projects upwardly from the ring 11 and forms a bearing for e rotatable post 23 which has e turn-stile 24 et its upper end. This turn-stile when in its norme] position es shown in Figs. 1 and 4, permits the tone erm to freely swing on the journal screws 16. However, if 1t is desired to remove the needle 2O from the record, the tone arm can be swung into the position shown in Fig. 2, and the turn-stile turned so that it engages under the edge 21 and thereby holds the tone arm in a. raised position to permit the ready chandging of the needle or for any other purpose` @sii-ed.

Eyelets 25 and 26 are respectively formed on the tone arm 18 and cup 5, and a coiled spring 27 connects these eyelets. This spring serves as a resilient counterbalance for the arm to relieve some of the pressure which would otherwise occur on the record when the needle is in engagement therewith and also serves to permit the tone arm to be easily swungr into its raised position.

The cup 5 serves as a receptacle for the sound after it has passed out of the tone arm, and the bottom and side of the cup causes the sound to rebound out of the openings 10.

The reproduced tone of a record through the aid. of my invention as above. described is extremely rich and quite distlnct, giving practically a true representation of the record being played.

My invention is extremely desirable as a portable device which can be readily carried and which can be quickly and easily placed in active position relative to any rotatable record and support.

While I have described my `invention :is taking a particular form, it will be understood that the various parts of my invention may be clnfuged Without departing from the spirit ti reef, and hence I do not limit Vmyself to the precise construction set forth, but consider hat I am at liberty to make such changes id alterations as fairly come within the scope` of the appended claims.

Having thus, -lescribed my invention, what I claim as nen` and desire to secure by Letters Patent is:

1. In a device ofthe character described, the combination of a cylindrical cup, a tone arm having its delivery end connected to said cup and adapted to transmit sound into said cup, and means formin a cylindrieal socket in which said cup ts and is free to rotate, said cup having an opening above its bottom to provide an outlet for said sound, substantially as described.

2. In a device of the character described, the combination of a comparatively shallow cylindrical cup open at its top, a tone arm movably connected to said cup and having its delivery end in alinement with the open to of said cup, and means providing a cy indrical socket in which said cup fits and is free to rotate, said cup having a lateral opening above its bottom to provide an outlet for`said sound, substantially as described.

stile mounted on the supporting structure andadaptcd to be swung under a portion of said tone arm to hold the latter in au inclined position, substantially as described.

4. In a device of the character described, the combinatie;l of a shallow cup, a tone arm having its, delivery end connected to said cup and adapted to transmit sound intJ said cup, and means forming a socket in which said cup fits and is free to rotate, said cup having an opening above its bottom to provide an outlet for said sound, substantially as described.

5. The combination of a tone arm, a cylindrical cup, standards projecting up- Wardly from the cup, means forming a pivotal connection between the standards and the tone arm, said tone arm having its delivery end positionedabove the top of the cup to permit the escape of the sound after it has been delivered into the cup through the medium'of the tone arm, substantially' as described.

6. The combination of a tone arm, a cylindrical cup, standards projecting upwardly from the cup, means forming a pivotal connection between the standards and the tone arm, said tone arm having its delivery end positioned above the top of the cup to permit the escape of the sound after it has been delivered into the cup through the medium of the tone arm, and a tray into which said cup rotatably fits, substantially as described.

7. The combination of a cup having an open top, a tone arm movably connected to the cup and having its delivery end in aline* ment ,with said openin and adapted to transmit sound into sai cup, and a tray havin a flat bottom and forming a socket in Winch said cup lits and is free to rotate, said cup having a lateral opening above its bottom to `rov1de an outlet forsaid sound, substantially as described.

In `testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.

FRANCESCO CIRELLI.
