TALKING-MACHINE.

Specification of Letters Patent. Patented Jan, 23, 1917.

Application filed September 25, 1913i Serial No. 791,821.

To all whom it may concern: H I

Be it known that I, CLINTON E. Woons, of Bridgeport, Connecticut, have invented a new and useful Improvement in Talking- Machines, which invention is fully set forth in the following specification.

This invention relates to talking machines, and more particularly to that class of talking machines in which a cylindrical record-tablet or record is mounted upon a suitable mandrel, and the sound-box and the tablet are driven by a suitable motor in the act of recording or reproducing.

The object of the invention is to produce a talkil'lg machine of this type, which shall be so constructedas to be highly convenient for desk use, or dictation purposes, which shall be compact, composed of a minimum nmnber of parts, and shall be noiseless in operation, free--from vibrations which would interfere with the recording or reproduction of the sound-vibrations, and which shall be capable of being started or stopped with ease by convenient manual manipulation. By manual, as herein used, is meant, not onlyoperation by the hand alone, but by the foot or other part of the body of the operator.

' Further specific objects are to provide for the lubrication of the machine, to the end that it may run fora long time without attention in this regard, and to connect the motor withv the operative parts by means of gearing, which shall be free from relative play which would produce vibration of the parts and inaccuracy in timing of the parts,

and generally, to improve the appearance and construction, as well as the convenience, of the machine.

With these objects in view, the invention, generally stated, consists of a basepiece,

preferably, circular in form, from which a column projects centrally upward and suptor is inclosed in the motor casing, having a shaft whose end projects into the gear Gas ing, and is provided with a worm meshing with a worm gear on one part of a two-part shaft, the other .part of said shaft being provided with a worm meshing with two worm gears, one of which is attached; to the mandrel shaft and the other to the feed-screw. A suitable clutch device is employed to connect the continuously driven member of this shaft at the will of the operator to the other member of the shaft, or to disconnect it therefrom. Said shaft and the gears cooperating therewith and the clutch device are all inclosed in the gear casing, while a clutch-operatin lever projects therefrom, and is provide with a suitable finger-piece in position to be grasped bythe operator when drawing the machine toward him, thereby closing the clutch and starting the machine, this action taking place against the tension of a spring, which automatically opens the clutch when the, finger of the operator is removed from said finger-piece. Or, one terminal of a Bowden wire may be placed in operative position in relation to,

said protruding clutch lever, the other terminal of the Bowden wire being in operative relation, yvith suitable lever mechanism, to

be actuated by the foot of the operator, or otherwise, to shift the clutch and start the mandrel, the reverse action being due to the tension of a spring, as in the case of a finger-piece; preferably, however, the machine is provided with. both the finger-piece andthe Bowden wire construction for actuating the clutch lever, to the end that either -may be used at will.

In the present invention, thebase of the may be employed for transmitting motion, and thereby greatly reducing the number of parts, and eliminating the play of parts and vibrations due to loosencss of parts, which heretofore existed in machines of this char-- acter. In the present invention, two worms are employed, one on the motor shaft and one on the shaft connecting said motor shaft with the mandrel shaft and the feed-screw, and in each instance provision is made for supporting the projecting end of the shaft bearing the worm, so that the latter cannot yield under the stress of operation but will always run perfectly true and accurate. Such support for the worm on the motor shaft is preferably secured by inclosing the worm in a hollow teat or huh projecting from the wall of the motor casing, which hub or teat has a slot cut in the side thereof to permit engagement of the worm gear with the Worm. The other worm referred to is affordedthe proper support by placing the worm gearing on the mandrel shaft immediately opposite the WQI'III gearing on the feed-screw shaft, to the end that the thrust due to the one shall. be offset or supported by the corresponding thrust due to the other I In addition, to the features above set forth, the invention contemplates the pref erable employment of a suitable speed-indicator, a correction device for indicating corrections or other data in connection with the dictated subject-matter, and a suitable speed governor for the motor, all of which last mentioned parts are likewise supported by the central upwardly-projecting column,

- and preferably directly by the motor cas- Other specific features and details of the invention will be pointed out in connection, with the description hereinafter cb'ntained.

The inventive idea involved is capable of recelving a variety of mechanical exp res sions, one of which, for the purpose of illustrating-the invention, is shown in theaccompanying drawings, but it is to'be expressly understood that such drawings are or the purpose of illustration only, and are not de signed to define the limits of the invention, reference being had to the appended claims for this purpose.

- In said drawingsFigure 1 is a top plan view; Fig. 2 is an end elevation of the lefthand end of Fig, 1; Fig. 3 is an end clevation of the right-hand end of Fig. 1; Fig. 4 is a front elevation of the machine; Figs. 5, 6 and 7 are details showing the manner of mounting and operating the Bowdcn wire .and its terminals for controlling the clutchshifting device; Fig. S-is a detail. showing the mandrel bearing supported by the gear casing; and Fig. 9 is a detail of the lubricating device employed in connection with certain of the bearings.

Referring to Figs. 1 to 4, 1 is a base or base-piece, preferably circular in form, and 2 is a suitable sup )orting column projecting upwardly, preferably from the center of said base-piece. The base 1 is preferably small and flat so as to occupy the minimum space. 3 is a shell or casing within which any suitable motor, preferably an electrical motor, is mounted, said shell or casing being secured to, and preferably formed integral with, the column A gear casing 4 is supported by the motor casing 3, and preferably is formed integral therewith. Said gear casing i has formed therein, and supported thereby, bew'ings for the mandrel shaft 5. Projecting from" the motor casing 3 opposite from the gear casing, is a casing 6, inclosing any suitable speed-governor" (not shown) for the motor, and any suitable speed-indicator 7, only the scale 8 and the needle 9 of which are shown.

The outer end of the casing 6 inclosing the speed-governor is provided with a closure-piece 10, from which projects, toward the front of the'lnachine, two curved arms 11' and 12 (see Fig. 3), the arm 11 supporting, one end of the feedscrew 13, and

the arm 12 supporting one end of the correction device 15, shown in Fig. 1. Preferably the two arms 11 and 12 are integrally connected forming a single bracket. Since the specific construction of the correction device forms no part of the present invention, it need not be further described herein.

Fhe motor shaft 16 has one bearing 17 in the left-hand end of the motor casing, as shown in Fig. 1, and said end wall of the motor casing has formed thereon, and preferably integral therewith, a portion, preferably in the form of a hollow teat or hub 18, within which the worm 19 on the motor shaft revolves, and by which it is supported on all sides, except for a slot 20 (Fig. 2) formed preferably in the under side thereof, through which slot a worm gear 21 enters to mesh with the worm 19. Said worm gear 21 is keyed to a shaft 22, to which is secured one member 23 of a clutch, the other member 24 of which clutch is secured to a sleeve 25 sliding on the other part 26 of the shaft, the two shaft parts 22 and 26 forming in effect a continuous shaft when the clutch mechanism is closed'and revol ing, together, said part 26, however, being stationar when the clutch is open, even though the motor be a continuously driven motor. On the end of the shaft part 26 is a worm-27, which meshes with a worm gear '2.) on the end of the mandrel shaft 5 on its upper side, and with a. worm gear 29 on its lower side, said worm gear 29 being fast on one end 30 of the foed screw 13, the other end of which has bearing in the arm 11, as before described.

' The base 1, the column 2, the motor casing 3,

and the gear casing 4L are preferably formed integral, and also preferably formed of cast metal, as cast aluminum, to the end that there can be no variation in the relation of the parts, and to the further end that the bearings for the respective shafts may be bored with great accuracy. It will be observed that the worm 19 on the end of the motor shaft 16 is supported by the hollow teat or hub 18 against the thrust of the worm gear 21, and that the two worm gears 28 and 29 on the opposite sides of the worm 27 act, the one to support the worm on one side, and the other to support it on the opposite side, so that the respective worms will perform their functions unyieldingly and with great accuracy and precision. This is a matter of much importance, since heretofore it has been deemed imprartical'ile to drive talking machine mechanism by worm gearing, though such. gearing is well known to be the most accurate and free from noise of operation and vibration. But by the means herein shown, it has been found possible to employ worm gearing, thereby securing the desirable results incident to its use, and avoiding the ob'jections heretofore existing in connection therewith.

The arm 12 not only supports one end of the correction device 15, as heretofore described, but also supports the outer end of the guiderod 31 for the sound-box carriage 32, which carriage is also provided with the usual or any suitahle'nut 33 (see Fig. 3) for on gaging-the feed-screw 13 to propel the carriage, in a manner well understood in this art.

Any suitable sound box, either for record ing or for reproducing, or both, may be mounted on the carriage, and as here shown, a combined recorder and reproducer 34 is mounted thereon, but since the specific construction of said recorder-reprodueer does not form any part of the present invention, the details of its construction are not specifically shown or described.

The several parts already described, that is, the motor, the mandrel, the sound-box and sound-box carriage, etc, are so related to each other and to the vertical column 2 that their combined. center of gravitylies substantially in line with the column and at an elevation which is low and is shown as being considerably less than the diameter of the base. Inasmuch as this machine is intended for desk use, the several parts are arranged compactly and at as low elevation as possible.

The clutch sleeve 25is engaged by the forked end 35 (see Figs. 2 and 5) of a clutchshifting lever fulcrumed in the gear casing at 36, and provided with a depending arm 37 projecting-out of the ear casing, upon which arm is pivoted a aposition to be grasped by the finger of nger-piece 38, in

movement of the mandrel and the feedscrew. Preferably, the pivot of the clutchshifting lever is in the form of a rock shaft. l0, one end of which projects outward through the side of the gear casing (see Fig. 5), and has keyed thereto a lever arm 4.1, and it will be observed that when said lever arm 41 is rocked in the direction of the arrow, it has the same effect on the clutch as when the lever arm 37 is rocked in the direction indirarted by its arrow; that is, it closes the clutch. to start the mandrel and the feedscrew.

Any suitable means may be employed for acting on the lever arm l1 to close the clutch, but by the present invention, it is preferred to employ a Bowden wire, one terminal of which is in operative relation with the lever 41, and the other in a suitable position to be actuated by the operator, as for example, 2n the floor, where it may be actuated by the cot.

Referring to Fig. 5, 42 is the Bowden wire, 43 the terminal in operative relation with the lever arm 41, and 44 is the Bowden wire terminal. in operative relation with the bellcrank lever pivoted at 46, preferably on the interior of an oval casing 4&7, one arm 45 of the bell-crank lever being in operative relation with the terminal 44, and the other arm 45 being in the path of a thrustpin ]8, preferably provided with a head 49 upon which the foot is placed to depress the same against the action of a spring 50, one end of which is connected to the arm 45* of the bell-crank lever 45, and the other to any part of the casing 47, as a depending lug 51. In Fig. 5, the parts are shown in the position which they would occupy when the. clutch is open and the mandrel and feed screw standing. still. In Fig. 6 the foot member is shown with the parts in the position which they occu y when the pin' 48 has been depressed by the foot of the operator, thereby thrusting inward (from rlght to left in Fig. 6) the Bowden wire terminal 4:4, which thrust is transmitted to the Bowden wire terminal 43, moving the same 'from right to left, as shown in Fig. 5, and thus shifting'the clutch to close the same and start the mandrel and feed-screw.

Preferably the base-piece 1 is provided With means for starting and stopping the motor, th1s means being mounted on the base.

For the purpose of lubricating the bearings of the machine, holes are drilled in the walls of the casing, and a suitable lubricatmg device is inclosed therein. One of these devices is illustrated in Fig. 1, in which. all is the opening in the end of the wall of the motor casing, extending down to and through the bearing forthc shaftlb, and

55 is a wick in the lower end of said opening, one end of the wick bearing against the shaft 16. To the upper end of the wick is connected a spring 56, and 57 is a screw plug closing'the opening 5%, which opening between thescrew-plug 57 and the wick is filled with a suitable lubricating oil. By means of the screw-plug 57, the tension on the spring 56 may be regulated,thereby rcgulating the force-with which the wick 5.3 bears against shaft 16, an'dthe spring automatically compensates for any wear on the end of the wick, due to its contact with the shaft. This lubrication of the shaft at this point not only performs the usual function of lubricatinga shaft hearing, but in addition there-" to, performs the very important function of simultaneously lubricating the worm 19 thus insuring smooth cooperation of said worm with the worm gear 21; in other words, lubricating the worm and worm gear by; reason of the small amount of oil which is fed from the shaft bearing 17 out onto and along the worm 1S), and from it'to the worm gear 21.

Preferably, the parts are all soproportioned, and the location-of the supporting column 2S0 arranged that said column is approximately at the center of gravity of the machine, or in a vertical line passing through the center ofgravity, to the end that the equilibrium of the'machine may be readily maintained. The machine of the -p'rcsent invention is designed, primarily, for desk use, much as a telephone is employed upon a desk, to be 'drawn toward and pushed back from the operator, and it will be perceived that, by reason of its small size, due to its compactness, itseqmlibrium,

its freedom from vibrations that would. interfere with its accuracy of operatlon, and

the facility with which the mandrel may be stopped and started,-as well asthe conven- 'ient arrangement of the correctlon device, and the location of the speed-1nd1cator,'1t
