TALKING MACHINE.

Application filed April 16, 1920, Serial. No. 374,271.

To all 10 [tom it may con cern Be it known that I, JOHN A. FERN, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in T alking Machines, of which the following is a specification.

The object of my invention is to produce a simple, unique, and highly efiicient talking machine, which shall possess a marked degree of utility.

In carrying out my invention, I place the the parts of a talking machine into a more desirable combination and arrangements, so that the tone will be improved; that its volume and strength can be modulated conveniently, readily and perfectly, and the appearance of the machine enhanced, and its shape and contour is of such a nature that all the parts are positioned to produce a superior talking machine.

In the accompanying drawing, forming part oi this specification.

Fig. 1, is a perspective view of my new talking machine,

Fig. 2, is a front view, parts broken away to show construction,

Fig. 3, is a longitudinal section, showing shutters closed, parts broken away, to show construction,

Fig. 4, is a similar view showing shutters open and parts broken away to show construction,

Fig. 5, is a similar view showing lower shutter only partly open, parts of the machine being broken away,

Fig. 6, is a plan view, the lid and inner cover removed showing shape of horn,

Fig. 7, is a section on line 7, 7, of Fig. 6,

Fig. 8, is a section on line 8-S of Fig. 3, parts broken away to show construction, and

Fig.9, is a view same as shown in Fig. 6, of a modified form.

The body of the machine is composed of side walls 1 and 2 and bottom 3, the walls merging and assuming a rounded form at the rear of the machine as shown at 4, the wall 2 also curving inwardly to form the rounded shape 4, at point 5, thus the frame is narrow at the back part and wide at the front. as shown.

This frame is supported on legs'G. A

cover or top 7 is placed on the frame of the machine, preferably hinged at 8 to side 1 and is held up'by a supporting rod 9.

At the front of the body part or frame, I place cross strips or bars 10 and 12 and midway bet-ween them I place a division board 13; this division board or strip being present preferably where the sides are stepped as shown at M; by this construction one halt (the lower) of the front, sets or extends forward or beyond the upper half of the front as shown.

In the rear end of the machine is a chamber 15, and this chamber is covered by a removable cover or lid 16; on the bottom of this cover 16 are placed the motor and other working parts which are not shown, as they are or the usual construction and are accommodated in the chamber 15.

On the top of this cover 16, I place the record holding disc 17 and the tone arm is marked 18; the tone arm extends down through the cover 16 and is connected at this point to the inner end of the horn 19, see particularly Figs. 6 and 7. The horn then extends forward in a curved form hugging the contour of the side 2 until it reaches the point 21, where it extends outward and flares and widens to form the amplifier or chamber 22, the inclined board 23 forming the .top of the amplifying chamber.

At the front of the machine and at the front of the amplifying chamber 22, I place two shutters or fall boards 2 1 and 25; the shutter 24 being pivoted at the point 26 and the lower shutter 25 being pivoted at the point 27.

From the bottom 3, I extend a lyre composed of the two element or members 28 and 29 held together at bottom by a foot piece 30.

In the lyre, I provide two long levers or push rods, 31 and 32, connected at the bottom to back of pedals 33 and 34c, pivotally connected at 35. These levers 31 and 32 extend upwardly and at their top pass through guides 36, their upper-ends striking against a plate 37 on a rocker arm or rod 38 to which it is rigidly attached. The rocker arm is guided in brackets 39 and is L shape in the present instance, (see Fig. 8). At the end of the rocker arm 38, is provided a link 40 through which the rocker arm passes. At its other end, the link 1-0 is pivotally connected to the lower shutter 25 as shown at 41.

On the side of the machine, I place a bracket 42, onto which I pivot or fulcrum alever 43, at its top end provided with a short arm or link ad, which is also connected to the upper shutter M, at point 4:5.

If it'is desired to operate the shutters or fall boards 2% and 25 the operator passes on the pedal 34, this forces up the rod 32, and its top end strikes the plate 37, this tilts the rocker arm 38, which operates link a0, which in turn pulls down the lower shutter 25, (if the treadle is only slightly pressed upon), forcing the shutter and parts to assume the position shown in Fig. 5, where, it will be observed the shutter is only approximately half open, thus the sound emitted from. the amplifying chamber will be softand mild and not loud; if it is desired to force the shutter entirely open, the pressure on pedal 3a is increased, this pressure, through rod 32, rocker arm 38 and link 40, forces the shutter entirely open, as shown in Fig. 4;. This last operation also forces open the upper shutter 24 as follows; when the shutter 25, as shown in Fig. 5, only half open, on account of the slight pressure used, as above set forth, to open it only partly, it lies against the lever 4L3; then, when greater pressure is exerted, the shutter 25 presses against and pushes the said lever 43, this operates link 44-, which being pivot-ally connected to the upper shutter 2d, at to, forces the shutter open, (see particularly Fig. 4:).

If it is desired to close the shutters the pedal 33 is stepped upon and pressed, and this operates rod 31 upwardly and forces it to engage the plate 37 on the opposite side, tilting the rod 38 back into normal position, thus forcing link a0 to push the shutter 25 up into closed position; by reason of the shutter assuming normal closed position, pressure on the lever 4:3 is released and the upper shutter 24: falls back into normal closed position.

In Fig. 9, the horn 19 is very short and the time arm 18, connects with it at the point where the amplifying chamber 22 he gins; when this construction is used the tone or sound waves do not need to travel far before reaching the amplifying chamber 2'2.

In Figs. 1 and 3, the shutters are all shown opened, in Figs. 2, 3 and 8 they are shown closed and in Fig. 5, the lower shutter is shown partially open.

When the shutters are entirely open the full volume of sound is emitted from the amplifyingchamber.

It will be readily observed that my system and mechanism for operating the shutters, is simple and convenient and efiicient in operation.

It will also be observed that the arrangement of the parts is unique, compact and desirable, for the formation of a talking niachine.

I wish to be understood as claiming any modifications which will fall within the scope of this specification.

hat I claim as new and my invgition and desire to secure by Letters Patent is? 1. The combination with a talking machine having an amplifier, of a. plurality of movably mounted shutters for controlling the emission of sound from the mouth of the amplifier, means for actuating one of said shutters, and means connected to the other shutter and engage-able with and disengageable from the first mentioned shutter for causing operation of the second mentioned shutter only after the first mentioned shutter has completed a portion of its movement.

2. A. combination of the kind defined by claim 1 in which the means for operating the second mentioned shutter includes a pivotally mounted lever positioned to been gaged by the first mentioned shutter, and a link pivotally connected to the second mentioned shutter and to said lever.

3. A talking machine including a. shallow casing having sides provided with front edges of step formation, an amplifier within said casing and having its mouth arranged at the front of said casing, aplate extending across the mouth of said amplifier and dividing said mouth into upper and lower openings, a shutter for closing the upper opening, a second shutter arranged forwardly of the first mentioned shutter and adapted to close the lower opening,

means for actuating the second shutter, and means connected to the first mentioned shut ter and engageable with and disengageab-le from the second mentioned shutter for causing operation of the first mentioned shut ter only after the second mentioned shutter has completed a portion of its move ment.

In testimony whereof, I affix my signature at Cincinnati, Ohio, this 13th day of April, 1920.

JOHN A. FERN.
