' SUPPORTING FRAME FOR TALKING-MACHINE MOTORS.

Original application filed May 15, 1918,,Seria1 No. 234,809. Renewed November 16, 1922.

I '0 all whomtt may concern 'roN, a citizen of the United States, and a resident-of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Supporting Frames for Talking- Machine Motors, of which the following is a specification.

The present invention relates to a driving mechanism and a steel supporting frame therefor adapted for use in connection with sound reproducing machines. The invention has for its object to provide an improved general combination be tween the driving mechanism for a talking machine and e a supporting frame therefor including anovel type of built up steel supporting structure so designed as to be capable of being made under efficient standardized manufacturing methods and so con structed as to permit of anovel arrange ment of the entire driving mechanism relative tothe supporting frame, thus forming a novel combination, of means having certain advantages in securing an accurate alignment and efficient association of the driving means of a talking machine as well as providing a more rigid, durable and serviceable supporting frame capable of being manufactured with a considerable saving of material and labor. 1

Other features of this invention relate to the construction of the frame per se, including the substitution of a sectional, interconnected steel frame for supporting a driving mechanism of a talkingma chine instead of the type of cast iron frame heretofore used whereby certain inherent disadvantages in the prior forms of construction are overcome and an improved type of frame is obtained. Moreover, by constructing a steel frame made of several parts, each part may be manufactured in quantities independently of the others and the several parts when thus properly made, will, so accurately interfit that no aligning, reaming of openings or machining of the assembled mechanism is neces sary.:

Further objects .of this invention are to provide a structure of this character which will more=readily withstand any possible strains imposed upon the mechanism, this being accomplished by reason of thegfact Be it known that I, ISAAC FRANCIS Bun that the several sections of the supporting frame are so interrelated and tied together that a possible strain received by one of the sections is transmitted to and absorbed by ,certain of the others rather than imposing the entire strain on one part. Moreover, there is thereby provided a frame construction which is light, strong and rigid the several elements is replaceable if one of the same should become distorted or broken, thereby avoiding the necessity of replacing the entire supporting frame in such an emer 'ency;

Further ob ects of this invention are to so construct the various elements of the type of frame mechanism referred to, that the assembling of the same is greatly facili-1 tated, each part being complete in itself, including means for securing together the several parts, thus avoiding the necessity for separate connecting means, such as bolts or nuts, with the result that the cost of assembly is relatively low and, moreover,

a particularly rigid supporting frame is.

provided which is unlikely to become loosened, and an accurate alignment of the various elements of the driving mechanism for the talking machine is also insuredQ Other objects of this invention, as will appearfrom the specification and drawings forming a part thereof, reside in the details of construction; the particular materials employed; the, particular shape given to the various elements;,the manner in which the, same are assembled; and the combination above referred to between the supporting frame and the driving mechanism aswell as the assembled relation of the elements thereof in saidframe. v

It is to be understood that many of the details of construction illustrated herein may be variedwithout departingfrom the essence of the invention in its broader aspect, and

the drawing forming apart hereof is mere 1y illustrative of one typeof construction driving mechanismand supporting frame constructed and arranged in accordance with this invention, while Fig. 2 is a side elevation thereof. Fig. 3 is a perspective view of the supporting frame with the driving elements and governor and other parts of the mechanism. removed therefrom. Fig. 4 is a plan View of one of the frame plates employed,- while Fig. 5 is a similar View of part of a tie plate used. Fig. 6 is a sectional view partly in elevation showing the method in which the bearings are assembled to the plates of the supporting frame construction.

The type of driving mechanism illustrated herein includes a motor or driving element, a transmission mechanism to the turntable of the talking machine and a speed regulating mechanism including a governor and a: regulator. The supporting frame which I have provided for the driving mechanism,

while having certain inherent novel characteristics of its own, as suggested above, is also arranged to form a combination wlth 7 the driving mechanism employed by reason of the fact that the entire driving mechanism includes, as a part thereof, a plurality of shafts located at a certain angle one with relation to another and the frame, by reason of its construction, is adapted to form a unitary supporting means for the mechanism and form bearings for said angularly arranged shafts. Thus in Fig. 1 there is illustrated a spring motor supported on a horizontal motor or power shaft 10 and including. a plurality of spring barrels or power "elements 11 and 12 adapted, when stored with energy, to drive the gear 13. The turntable spindle 14 is arranged at an angle to the shaft 10 and may be driven by the gear 13 on the shaft 10, by means of the worm 15 on the spindle 14. In the particular form illustrated there is thus a direct rectangular drive between the motor or power shaft and turntable spindle. The speed of the rotation of the spindle 14 is controlled by a governor 16, the governor being driven from the spindle 14 by gear 17 meshing with a worm 18, for example, on the governor shaft 19. In the type illustrated, the governor shaft 19 is located at right angles to the spindle 14 and parallel with the motor or power shaft 10 although it is apparent that the shaft l9 could be located in an inclined position. if desired. and moreover, the motor or power shaft 10 need not necessarily be located horizontally, but might be arranged in an inclined position. will be therefore seen that in the type of motor employed there is an angular drive between the motor shaft and the spindle and between the spindle and the governor. Moreover, the governor regulator 20, in the type employed herewith, in cludes a rotatable shaft 2lc'arrying a pad 22 to engage the governor disk 23, the shaft 21 being located for convenience of arrangement and construction at an angle to thesupport certain parts of the driving mechanism, this result being due both to the improved type of frame and to its use with the general type of driving mechanism just described.

One form of frame adapted to perform these functions, as well as having certain inherent advantages of its ow"nsuch as in its method of manufacture, construction and use in operationis illustrated in Fig. 3 and shown in Figs. 1 and 2 with thedriving mechanism supported therein. Generally speaking, the type. of built up steel frame which I have designed includes a plurality of frame plates 30, 31 and 32 and a plurality of tie plates 33, 34, 35 and 36, the frame plates being adapted to support the power elements through the shaft 10, while certain of the tie plates support the turnable spindle 14 and regulating rod 21. The governor 16 likewise may be supported by certain of the frame plates which support the motor or power shaft 10. These frame plates and tie plates are formed of steel and may be readily punched out by a suitable punching press, each plate being so shaped as to properly support the various elements of the driving mechanism for the talking machine just referred to, being provided with proper openings for bearings for this purpose, and at the same time so constructed as to be secured to the adjacent plates without the use of tie bolts or nuts. One of the frame plates 32 is illustrated in Fig. 4 where it will be seen that the same is provided with certain lugs or extensions 37 adapted to extend into corresponding openings 38 in the several tie plates. one of which is illustrated in Fig. 5, the lugs 37 being headed over to tie the frames and plates together. Each of the other frame plates andtie plates are correspondingly shaped and provided with the necessary openings to receive the bearing bushings for the shafts which they support. Thus the plate 32 is provided with two openings 39 and 40, the opening 39 adapted to receive the bearing hub '41 for supporting one end of the motor or power shaft 10 while the open- 1,460,406 r j y a 3 ing 40 receivesthe bearing bushing 4210f the winding shaft 43; As apart of. this in.- vention,the various bushings forming the bearingsfor the shafts of the driving mechanism, such as the bushings 41 and 42, are of such a type as may be turned out on automatic machines and'when inserted into their receiving openings in the frame plates and tie plates, the same may be staked or spun over to securely position the bushings therein. This method of construction isillustrated in Fig. 6 wherein itwill be seen that the bushings 41has been secured .tothe plate 32 by spinning over an edge 44 to grip the plate 32 between aishoulder45 on tlie bushings 41 and the spun over flange 44. It is apparent, however, that various other means could be readily employed for accurately positioning the bearing bushings into the frame plates. By, constructing the frame plates, tie plates and bearing bushings as set forth, each ofthese several ele: ments of the supporting frame is preformed complete in itselfand may be independent: ly made with reference to the, others and when assembled each part will accurately and properly interfit as intended, thus in suring the accurate construction of the frame and an accurate alignment of the bearings without necessitating any later ad: justment or machining of parts or other operation upon the completed frame.

The particular location and'arrangement of the several bearings, necessarily corresponds with the type of motor and driving mechanism for which thesupporting frame is designed. In the type shown, the frame plates 30 and 31 are provided with lbushings 48 and 49 which align with the bushing 41 to support the motor shaft 10, the shaft being thus supported at its ends and near its middle. Moreover, each of the frame plates 30 and '31fis provided with aligned bushings 50 and 51 for supporting the governor shaft 19.. The tie plates 34 and 36 are provided with similarly constructed and positioned bearing bushings 52V and 53 for the spindle 14, while the tie plate 35 is provided with the extendedbush- 'ing 54 for supporting the shaft 21 ofthe governor speed regulating attachment. 1 It will thus be seen that the. correlated frame plates and tie plates form agsupporting frame made of punched out, built up steel section s, tied together and interrelated in the manner illustrated,.thereby'providing a strong, relatively lightsupporting frame of maximum strength with a. minimum amount of material, with other advantages in in-.

creased efficiency in manufacture of the separate'elements andthe assembly of the same.- Itv is also apparent that by reason of the particular construction employed, certain of the frame plates perform the function of supporting the motor shaft and governor shaft, for ezrample, while the tie plates, by their particular construction and the con struction or type of motor; with which they are employed, operate to perform a double function of tying the frame, plates together and. forming an accurate support for-the talking machine spindle or governor regulati'ng arm, or in other Words, all of the essential driving elements of the mechanism are properly supported directly on certain frame parts, andin this mannerno special means is necessary for supporting the mechanism in the frame. a

To position the frame and mechanism in a talkingmachine, the supporting frame is provided with a three-point suspension in the cars 60, 61 and 62 by which the mechanism may be secured to the motor board 63, shownin Fig. 2. For this purpose there maybe employed a plurality of bolts 64 passing through the motor board: and the supporting ears and, if desired, a sound in sulatingwasher 65 may be interposed between the motor board and the supporting ears. i I a a a r In F 1 there is illustrated at70, aspeed indicator which is also. carried by thesup porting frame and operativelyv associated withthe governor 16. One type of indicator includes aipointer 71 adapted to move over a scale on the motorboard to-indicate the speed of rotation of theturntable. This indicator is carried by ,asupporting plate '72 which is secured to the tie plate 35 by setiscrews 73. The indicator 70 is provided withan arm 74 adapted to engage the governor disl23 and be moved thereby as the same moves longitudinallyon the governor shaft. The movement of the arm 7 4 is transits operation. It will be seen that the sec tional, built up steel; frame which I have provided forms 1 the unitary supporting means for the driving mechanism of the talking machine and at the same time substantiallyallthe essential elements of the driving mechanism are'directly supported by certain parts of the frame, thus avoid ing the necessity for any special support ing vmeans for any of the elementsof the driving mechanism. It will be further understood. that by reason of the construction described, the frame itself has many inherent advantages hereinbefore more fully pointed out.- The several parts maybe readily manufactured by machines and turned out in large quantities independently 7 one of the other and when, assembled are so scribed.

accurately made that the completed frame requires no. additional manipulation to form with integral tying means for joining each section one with the other,-result1ng 1n the rigid construction referred to, and the construction as a whole forms one efficient means for attaining the objects set forth in the statement of the invention, but it is apparent that certain-of the details may be altered and many modifications of the precise structure'made without departingfrom the spirit and scope of my invent-ion as set forth in the appended claims. I

Attention is called to the fact that this invention is intended to cover various other types of motors than that illustrated in the drawing, for example a single barrel 12 may be used for housing a suitable spring mechanism for driving the turntable spindle let in which case the barrel 11 would not be used and the end framepla'te 32 would also be omitted. Furthermore, it is apparent that a single springer three spring motor could be used as well as a two spring motor orfour spring motor, the four spring being the type illustrated in'the drawings. 1
