SOUND-BOX.

Specification of Letters Patent.

Patented April-1'7, 1906.

Application filed September 2. 1905. Serial No. 276,894.

To all whom it may concern;

I Be it known that'l, CHARLES A. G. PRI'rcn- ARD, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Sound-Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

M invention relates to sound-boxes, and has or its object to provide in a simple and inexpensive construction means for storing and feeding styluses to the stylus tube or retainer, also means for securely retainin the stylus in place during the operation 0% the machine, also an improved form of resilient support for the stylus tube or retainer.

Generally speaking the invention may be arts illustrated in the drawings, described 1n the specification, and embodied in the claims hereto annexed.

In the drawings, Figure 1 represents a front elevation of a sound-box constructed in accordance with my invention. Fig. 2 represents a side elevation, partially in section, of the device shown in Fig. '1. Fig. 3' represents an enlarged sectional detail showing the construction, of the stylus tube or retainer and of the support therefor. Fig. 4 represents an enlarged sectional view on the line 4 4 of Fig. 1, and Fig. 5 represents an enlarged sectional view on the line 5 5 of Fig. 1.

Describing the parts by reference-numerals, 1 represents the body of the box, said body being circular in outline and havinga c lindrical side wall 2 and a head 3, carrying tl ie usual connection 4 for the horn or mega As will appear more particularly from Fig. 2, the lower portion of the box projects forwardly andis provided in the lower portion thereof with a slot or opening 5 forthe reception of the stylus tube or retainer. Adjacent the head 3 the side wall is provided with a groove 6 for the reception of the mica disk 7 and theretaining rings or washers 8, which may be of rubber or any suitable ma.- terial.

- The upper forward end of the body is cut away for the reception of a plate or member 9, which plate or member may be removably secured to the box-body by means of screws 10. A pair of ledges or shoulders 11 are provided'at the junction of the lower incl ned portion with the upper portion, said ledges or shoulders receiving the lower end of. said or completed plate or memberQ. This plate or member 9 is scored to provide a' vertically-arranged groove orchannel 12 for the reception of a plunger 13 and a groove or channel 14, said latter groove or channel being inclined with respect to the former and branching therefrom at a point belowthe lower end thereof. The metal between said channels is cut away at 15 to. permit the stylus 16 to be delivered into the channel12 when the plunger 13 is elevated sufiicientl 17 denotes a fee or supply tube for styluses, said tube being of any desired length and having at its up er end a funnel-sha ed inlet 18 and being etachably connecte to the upper end of the plate or member 9 in aline'ment with the groove or channel 14 therein. The chambers 12 and 14 are closed by means of the transparent plate 19, said plate being secured to the member 9, as screws 10 and 21. i 22 designates the stylus-retainer. This retainer consists of atubular member 23 in alinem'ent with the channel 12. The lower end of the member 23 is contracted to embrace the lowered tapered portion of the stylus 16' and is provided with oppositely-105 cated slots 24, extending through the lower end thereof. The metal being resilient, a friction-clamp is thus provided, which portion prevents the stylus from dropping out of the lower end of the tube 23. As the frie tion necessary to retain the stylus against upward dis lacement would necessarily be great and Won (1 interfere with the easy removability of the stylus from the tube when desired, 1 rovide a chuck for the upper end or head 0 the'stylus, as follows: At the proper distance from the lower end of thetube a perforation 25 is provided, the upper Wal of said perforation being beveled at 26 to receive the inwardly-bent lower end 27 of a flat spring 28. tained in place by means of a sliding collar 29, surrounding the tube'23. The surface of the tube is'cut away or flattened to receive said spring and to allow the outer surface thereof to be substantially flush with the surface of said tube, thereby permitting the sleeve to be adjusted to permit removal'of the spring and to vary'the resistance thereof to the passage of the stylus and above the one inthe clamp. The lower end of the spring projects within'the bore of the tube a sufliby pins or rivets 20 and the 7 by metallic washers 33,

cient distance to engage the upper end of the head of the stylus 16 and prevent upward dis lacernent thereof.

n order to provide a resilient support for the stylus tube or retainer, I employ a flat spring 30, the end ortions of which are suitably secured to a ridge 31, carried b the lower end of the box-body, said bridge iieing secured to the box-body, as 1) screws 32. This spring is spaced from the bridge 31, as through which and the bridge and spin extend the rivets 34. The. central portion 0 said'spring is provided with anopening 35 for the reception of the tube 23, the portion 36, which extends through said opening, being provided with a screw-thread. By means of nuts 37 and a washer 38 said tube is readily and adjustably secured to said spring. ,The bridge provides a firmsupport for the spring at the time when the plunger 13 is beingoperated to eject a stylus therefrom, while the slight spacing of said spring from the bridge enables it to vibrate with the stylus-tube and transmit such vibrations through the connection 39 to the disk 7.

It will be observed that the tube 17 and a portion of the channel 14 therebelow provide a magazine for the storage of styluses end to end. In order to retain such styluses in'the magazine until such time as it may be desirable to su ply them to the tube or retainer 22, I emp oy a detent consisting of a flat spring 40. This spring is conveniently secured in placeby inserting an end thereof beneathvthe part of the transparent plate 19, which covers the arm or bracket 41, projecting. from the plate 9. This end of the spring is convenient y secured by the screw 21. slot 42 is provided in the plate 19, extending from a point" near the screw 21 across the channels 12 and 14. The spring 40 lies with-' in this slot and fits more or less closely against the plate 9, said plate being recessed, as shown in Fig. 4, to retain the sprin against lateral movement. The free en of the spring is bent inwardly at 43 toengage the lowermost stylus in. the magazine and hold it and the stylus thereabove from being supplied to the portion of the channel '14 below said spring.

The plunger 13, to which reference has been made hereinbefore, is flattened throughi I out the major portion of its length, as will apw to he slid freely beneath the sprmg 40. Thetion to pear from Figs. 1 and 4, thereby enabling it lower end 45 of the plunger is circular in sec- 1permit it to engage the inner wall of the sty us tube or retainer 22. distance above theportion 45 it is provided with a cam or projection 46 to engage with the lowermost stylus of the magazine. The

lower end of this projection or cam 46 is beveled, as appears 1n Fig. 1, and the upper end is downwardly inclined to correspon nearly A suitable to the contour of the screw 44, which serves as a stop to prevent the withdrawal of the plun er, the ortion of the plunger in such case eing indicated by dotted lines in Fig. 1. The screw 44 has a wide head flattened on its under surface to engage the flattened surface of the plunger and prevent it from being .turned out of operative relation to the spring 40', the plate 9 being countersunk to permit adjustment of said screw.

With the parts in the position shown in full lines in Fig. 1 it will be apparent that by elevating the plunger to the position shown in dotted lines the stylus 16 in the lower part of the chamber 14 will be free to fall into the lower part of the channel 12. Before the end 45 of the plunger clears the lower end of the said stylus the projection 46 will have passed above the spring 40 and said spring will have returned to place in engagement with its stylus, thereby permitting only the stylus 16 to pass into the lower portion of the channel 12 and thence into the tube 23. On its return movement the end of the plunger 45 sufliciently covers the lower end of the channel 14 before the engagement of the spring 40 by the projection46 to prevent the stylus re leased by elevating the sprin from passing into the channel 12. It wil thus be seen that in normal operation the styluses willbe fed one at a time into the stylus-tube 23 by the movement of the plunger. As the lower end of the tube 23 may offer considerable resistance to the discharge of styluses therethrough, the provision of the bridge 3 is an important feature as limiting the bending of the spring30 and preventing injury to thedisk'7 or the connection between the same and the tube.

' Aside froinits adaptability to eject styluses from the stylus tube or retainer the insertion of the plunger into said tube serves to lessen the amplitudeof vibration of the said tube and to correspondingly muffle or diminish the volume of sound emitted from the box, the amount of such reduction being proportionate to the distance the plunger is inserted within said tube. As it, is diflicult' to assemble the parts so that the stylus tube and plunger-groove channels are in exact alinement, it is not necessary to make the lower: end'of the plunger of exactly the same size as the bore of the tube, since with the parts slidablyout of alinement a ortion of the lower end of such plun er wil engage a portion of the inner wall of the tube to de crease the vibration thereof.

v While I have described the invention in detail, it will be obvious that such details may be modified ordeparted from more or less without avoiding the spirit of my invention, and I do not propose to be limited to such details except as they may bepositively included in the claims hereto annexed or rendered necessary by the prior state of the art.
