Application led April 8, 1897. Serial No. 631,268. (No model.)

To cti/Z whom it may concern.-

Be it known that I, GEORGE W. GoMBER, a citizen of the United States, residing ai' Oonyngham, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Talking- Machines; and I do hereby declare the following 1.o be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to talking-machines, and the advantages and details of construction thereof will be pointed out in the following specification and claims and illus trated in the accompanying drawings.

My object is to provide a machine of simple and inexpensive construction which while reliably performing the work required of a machine of the most elaborate and expensive workmanship may yet be placed upon the market at a low price.

To attain the foregoing end, it will therefore be apparent that the prime object will be to so construct and combine the various elements necessary to constitute a completelyoperative talking-machine that each of said elements may be readily formed without the necessity of employing` expensive machinery for such purpose, all of which will be readily apparent from the accompanying drawings, in which- Figure 1 is a ltop plan View of my invention, the tablet and mandrel being shown in section. Fig. 2 is a side elevation of the carriage and parts moving therewith. Fig. 3 is a section of the tubular holder on the carriage. Fig. 4 is a top plan View of the sound-box and neck therefor. Fig. 5 is a central section of lthe saine with its lid or cap removed. Fig. 6 is a central section of said soundbox cap. Fig. 7 is a front elevation of Fig. 1, showing a counter-balance for the soundbox body. Fig. 8 is a top plan View of, the sound-box and carriage shown in Fig. S. Fig. 9 shows a side elevation of carriage, showing sound-box removed and paring-knife in position. Fig. 10 is a detail of the paring-knife holder. Fig. 11 is a slightly-enlarged detail of stylus-holder. tail of the nut-section and carrying-spring therefor. Fig. 13 is a side view, on an enlarged scale, of the stylus mechanism shown in Fig. 2.

The numeral 1 designates the casing, designed to reliably house the spring-actuated or other form of motor, from which motion is communicated by suitable means to the wheel 2, which is iixedly secured to one end of the mandrel-shaft 3, while to the other end of said shaft is xedly secured the tablet-mandrel 4, carrying the tablet 5. Said shaft is adapted to rotate in a tubular bearing 6,Which is securely mount-ed in post 7, said post being erected on the housing l. Upon said housing are also erected standards S and 9,'

designed to form a suitable support and mounting for guide- shafts 10 and 11 and the threaded shaft 12, all of which are substantially parallel to the axis of the tablet-spindle. Guide-rod l0 forms the main guideway for the carriage 13, determining the direction of its lateral movement, While guiderod 11 passes through cam-slot 26 of cam 2 5 and forms a continuous bearing (parallel to the main guide-rod 10) for the outer or longer wall of said cam-slot, and said cam having pivotal connection with the carriage 13 by means of the arm 24, fixed thereto, it follows that the position of said slot with relation to said shaft determines the plane in which the lateral movement of the carriage shall take place, so that by a proper manipulation of the cam the sound-box is lowered into or lifted out of its operative position. Fixedly secured to the shaft 3 is the gear 14, which meshes with the gear 15, which carries gear 16. Said gears l5 and 16 rotate upon an axle iixedly secured to the arm 30, which arm projects from post 7. Gear 16 meshes-with gear 17 said gear 17 being fixedly secured to threaded guide-rod 12, so that motion from axle 3 is imparted thereto; but owing to the size and arrangement of said gears guide-rod 12 rotates much more slowly than the mandrel, the object of which will be pointed out hereinafter.

If found desirable, guide-rod 12 may be Fig. l2 is a perspective deheld in position by center points secured in posts 8 and 9 and taking into center bores in the ends of said guide-rod adapted to form suitable bearings for said center points.

The carriage 13 is provided with the tubular projection 18;, consi ituting the sound-box. Said box is provided with the lateral slot 19 and the nozzle 20. Said sound-box, with its slot 19, is adapted'to receive the head and neck 21 and 22, respectively, of the soundbox 23.` The width of said slot is somewhat greatei' than the thickness of said neck7 thus permitting a slight upward and downward play of the sound-box, which is necessary in the performance of its work. The tubular holder 18, by means of its nozzle 20, is designed to receive and support. the usual Flexible tube,

and owing lo the support the carriage receives from guide-rod 11 through the mediation of arm 2l and cam 25 the delicate operations of the sound-box are in no way affected by the weight of the carriage or by any other weight that maybe imposed thereon, (as by the mounting of flexible tubes or the like.) If found desirable, the outer end of' the sound-box 1S may be provided with a cap orot-her ret-:lining device, (not sho wn,) though it is thought that the sound-box head will reliably retain its position by gravity, as the outer end of the holder is inclined upward. Fixcdly secured to the carriage 13 is the arm 24, to which is pivotally secured the cam 25, having the cam-slot 26, and, as already pointed out, the position of said slot with re. lation to shaft 11 determines the depending position of the carriage and sound-box and the plane in which they travel hack and forth. It will also be observed that the carriage 13 is further provided with the slotted strapspring27, bent upon itself, forming the loop 2S. This construction permits the use of a longer piece of spring metal, and thereby secures geater resiliency. Said spring is designed to carry the threaded block 29, secured thereto at its free end. I prefer to provide the slot 27 nearly the ent-ire length of said spring to give greater resiliency and also permit the threaded block to be attached in position by screws entered from the rear side thereof, as shown in Fig. 10. It will be observed that when the carriage is in such position as to bring the pivoted arm of the sound-box into contact with the tablet the nutsection is also brought into engagement with the threaded shaft 12, and vice versa. When by a proper movement of cam 25 the stylus-point is brought into contact with the tablet and the nut-section 29 into engagement with the threaded shaft 12, lateral motion will be imparted to the carriage through said nut-section 29 and spring 27 as the tablet-spindle rotates. Since threaded shaft 12, as already shown, rotates slowly, a coarser thread can be employed in producing a standard or any given record than could otherwise be used. y

\ In the neck of thesound-box is the recessed cavity 31, which ext-ends outwardly through the sound-box head and terminates in the ared mouth 32, while its inner end opens into the inner space inclosed by the soundbox. When the sound-box `is in its operative position in its receiver or holder 18, the

'mouth 32 of cavity 31 will "egister with the 'sounds back and forth, since said llange is provided with a series of apertures disposed around its entire periphery a short distance apart. If preferred, that portion of the cap contiguous to the openingtin the neck may he entirely cut away. Lidy 36 may be held in its proper position on the soundbox by frictional contact or by a screw threaded union, as preferred.

I will now refer to the details involved in producing other parts of a completely-operative talking-machine, the constructionthereof being of the simplest character. In Figs. 7 and 8 I have shown a modified construction to be employed where it is deemed necessary to more reliably poise the sound-box in its operative position, and with this end in view I attach preferably to the outer end of the head 23 the laterally-extending arm 46, having connection with the counterpoise 47, the latter being formed of suitable material and size andpreferahly disposed in a plane parallel with the holder 18. By a nice adjust ment of the parts forming the counterpoise it will be apparent that the slound-box will be held in very sensitive or light contact with the tablet, and it will be further apparent that these parts may be very cheaply constructed and assembled.

As it is essential to a completely-operative talking-machine that a paring device shall be provided, I have produced adevice of this character of very simple and ready const-ruction, which I have illustratedfin Figs. 9 and 10. This paring device consists of the support or body 48, one end of which may be attached to any convenient point of the carriage, preferably at the base ofthe support or standard 24, after the soundbox haslbeen removed from the holder 18. Said support 43 maybe attached in any preferred manner and is provided upon its under side with the depending spring or knife-holder, which is of special construction and is more clearly illustrated in Fig. 10. Said spring-support consists of the main section 50, the upwardlyj-inclined section 51, and the anchoring-section 52, which is attached to the body 4:8 by screws or otherwise. The free end of the malin section 50 is provided with the downwardly-extendingintegrally-formed socket 53, in `which the knife 5L1is seated and reliably held to its work. The socket 53, it will be observed, is readily formed IOC IIO

by properly cutting away and bending the free end of the section 50. In orderthat the position of the knife may be readily adjusted, I seat in or near the outer end of the holder or body 48 the adjusting-screw 54a, which passes entirely th rough said support, the free end bearing against the upper side of the free end of the main section 50.

In Figs. l0 and ll I have illustrated a cheap but eifective means of mounting the styluspoint. By reference to Fig. 1l it will be observed that the said holder is formed from a strip of suitable material, thus providingthe anchoring-section 55 for connection with the sound-box body or base and with the inwardly-reaching section 56, designed to lie substantially parallel with the lower surface of the sound-bok body or support, while the free end is so bent that the edges thereof will rest alongside of each other, and it will be seen that if the point of a suitable tool or other object is placed between said edges before they are brought entirely together the socket 57 will be formed, in which the styluspoint 5S may be reliably seated and efficiently held by further closure of the edges, thus making it possible to strike the entire holding device from a single piece of material at one operation.

It is thought that the several parts constituting my improved simplified talking-machine will be found as thoroughly efficient as those of more elaborate design and construction, thus enabling me to accomplish the object specified.

The operation of the paring device, it is thought, will be clearly apparent, though it may be stated that after the device is secured in its operative position the knife may be brought into engagement with the surface of the tablet by a proper manipulation of the regulating-screw 54, the tension of the spring' being so disposed that it will extend normally upward that is to say, if the set-screw should force the knife too deeply into the tablet the recession of the knife will follow the withdrawal of said screw, thus producing a device of positive character.

In Fig. I3 I have illustrated in side elevation a stylus-holding device especially designed for use upon a sound-box whereon no weight is used. Itwill be seen that the standard 59 is erected directly upon the lower face of the body of the sound-box and is preferably bifurcated, thus providing a seat for the outer end of the pivoted lever 60 and the guides for controlling the lateral swing of the stylus-arm, the inner end of said lever reaching over the central part of the sound-box, with which it is cooperatively united by means of the usual link 6I. The outer or pivoted end of the lever 60 extendsslightly past the standard and is provided with a verticallydisposed aperture, in which is seated the lug or journal 62, formed upon the stylus-arm 63. It will be observed that the construction just described is of great simplicity, rendering the device especially applicable to a sound-box vpivoted in the manner specified inthis application. I admit that this method of mounting the stylus-arm would be found more or less impractical upon a sound-box not. provided with a weightand mounted in the manner common for mounting sound-boxes. I clai m, however, Atreat advantages for the construction, owing to the simplicity thereof, when it is used in connection with the means I have set forth for sensitively holding the sound-box body in its operative position, as the stylus-point will yieldingly follow the line of record or inscribe the same upon the tablet, as will be readily apparent.

Having thus fully described inyinvention, what I claim as new, and desire to secure by Letters Patent, is-
