JONAS W. AYLSWORTH, OF EAST'ORANGE, NEW JERSEY, ASSIGNOB, BY MESNE ASSIGNMENTS, T0 THOMAS A. EDISON, INCORPORATED, 0F WEST ORANGE, NEW
JERSEY, A CORPORATION 0F NEW JERSEY.
TALKING-MACHIN E.
To all whom t may concern.'
Be it known that I, JONAS W. AYLswoR'rH, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Talking-Machines, of which the following is a description.
e My invention relates to talking machines or phonographs, and my object is to produce a talking .machineof the type Whicr operates upon disks or flat sound records, which will permit the use of exceedingly thin records and record blanks, which, because of their thinness` are flexible, light, and inexpensive in comparison with the common type of comparatively ,thick disk records `known to the art.l Exceedingly thin -records of the character specified are more particularly described and lclaimedin application Serial No. 541,764, filed by me on even date herewith. Reproduction can be made from such records`on disk talking machines as known to the art with but most imperfect results, if at all, because such records have not suiicient backing in themselves for-the stylus to react against, and because also, when supported upon the usual turntable or record support, they will not lie sutliciently flat and even upon the support to permit the stylus to properly track the same and be fed thereby.
In my present invention, these difliculties are overcome in a simple and effect-ive manner, whereby it is made possible to form records on exceedingly thin disks or other fiat surfaces and reproduce the records formed thereon. Accordingly, my invention comprises a table or support for an exceedingly thin flat record together with means for maintaining the record firmly in uniform contact with the supporting surface. The record is so held. in contact with the supporting surface by means creating a uniform difference in pressure between the upper and lower sides of the record, the pressure upon the lowerl or under side of the record being the less. y 1
More specifically, I provide a record support of porous material and exhaust the air from the pores of this material and beneath the under surface of the record to hold the same upon the table by suction.
Attention is hereby -directed to thel accompanying drawings, forming part of' this specification and illustrating a number 0f watys in which my invention may be carried ou vertical cross section t rough a t-able and disk sound record supported thereby, together with means for creating suction to hold the rcord upon the surface of the table and embodying one form of my invention. F ig. 2 represents a partial plan view of the same. Fig. 3 represents a view similar to Fig. 1 of a modified' form of my invention. Figs. 4, 5 and 6 represent similar views of other modifications.
Referring to the drawings, the suction table is provided in all of the modifications with an outer annular solid or non-porous rim 1 designed to form a more or less air tight joint with the record disk 2 beyond the portion of the disk 2 bearing the sound record 3. A solid or non-porous center 4 is likewise provided, which is designed to form a relatively air tight joint with the disk inside the record-bearing portion 3 and between the same and the central hole 5 of the disk. The table between the outer rim porous material 6. This porous portion of the table is designed to form the bearing surface for that portion of the under side of the disk opposite the record bearing sur- Pface thereof. ,It may be formed of any porous material from which the air may be exhausted, and'is preferably formed of a compact material as for example, plaster of Paris, porous cement or biscuit porcelain or unglazed earthenware. The upper surfaces of rings 1 and 4 and the porous portion 6 should besmooth and hard in order thatl the exceedingly thin record 2 placed thereupon may be reproduced properly. Whenv the record is placed upon the table, the air beneath the disk andl in the pores of the table is attenuated by suction, so that atmospheric pressure above the disk will hold the same firmly against the table, which will support the disk at so many points as to produce practically a solid portion for the same.
The desired suction maybe obtained in 1 and the inner portion luis formed of aQ face of the table comprising the upper sur` Specification o/f Letters Patent. i PatentedfMay 27, 19.13. l
In the drawings; Fi re 1 represents a a number of ways. For example, as shown in Fig. 1, the outer non-porous ring 1 formed of any suitable material, has a horizontal disk 7 secured to or integral therewith extending below the reco'rd 2 and the porous lportion 6. This lower disk-shaped member 7 is secured to or integral with the central portion 4 and also has secured to or integral with it a cylinder 8 closed at the bottom/'and coaxial with the central spindle 9 of the talking machine through which the rotary movement of the supporting table is transmitted. A plunger 10 is mounted to reciprocate vertically'within the cylinder 8, this plunger having a stem o-r reduced portion 11 y-extendinor upwardly therefrom through the centnaperture of the disk 2, the stem being guided' by sleeve 12., A number of passages 13 extend through the p0rous portion 6 of the table and connect the same with the interior of cylinder 8. Passages 13 are also connected to an annular space 14 which is preferably provided between the periphery of the porous portion .6.- of the record support andithe non-porous vrlm 1.- A passage 15 is provided between the interior of cylinder 8 and the atmosphere below t-he under surface of plunger 10. l When it is desired to support a record as 2 upon the table for reproduction from the record, the llatter is placed upon the table and plunger 10. is drawn upwardly by means of the knurled head 16 of stem 11 protrud- -ing above the record surface, this upward movement forcing most of the air out from under record 2. Plunger 10 is then pushed downwardly creating a vacuum within chamber 8 above the plunger within the pores of porous material 6 and within all the air passages below reco-rd 2 and between the same and the non-porous disk 7 and cylinder 8. The record will now be held upon the table firmly by suction. Suitable means may be provided for holding the plunger'lO in its lower position. A suitable means is shown in the drawings in which a small pawl 17 pivoted at 18 to the central portion 12 of ring 4 is adapted to be pressed into an annular notch 19 formed around the periphery of stem 11 of plunger 10. Pawl 17 maybe provided with a vertical upstanding lug 20 which may serve as a finger piece for pushing the pawl into its holding position. Stem 11 of plunger 10 may also be provided with a circular notch 21 with which pawl 17 may co-act to hold the plunger in its raised position. When the record lis to be removed, the plunger is raised to its integrall therewith to. the table and record ,A bellows-like member 22 is mounted below disk 7 and surroundingthe central spindle 9 of the talking machine. This bellowslike member comprises a fiat rigid bottom plate 23 which is closely mounted' upon spindle 9 to slide upon the same and/the expandible bellows member 24 of any suitablefiexible and air tigl1t.1naterial which takes the form of an annulus, the outer pe' riphery of which is attached tothe outer solid rim 1 of the record support, and the inner periphery of which is attached to the bottom of plate 7 adjacent to the central po-rtionli of the table. Plate 7 is perforated as shown. In place of plunger 10 and stem 11, a stem 11 having a knurled head 20 is provided, stem 11 being adapted to slide vertically within an axial hole formed in spindle 9 and' through the center opening of the disk 2. Spindle 11 is provided with arms 25 `bearing upon the upper surface of plate 23 of .bellows 22 for forcing the same downwardly when stem 11 is depressed. Spindle 9 is provided with slotted guideways 26 in which arms 25move as stem 11 is reciprocated. Stem 11" may be provided with circular notches coact-ing with a pawl,v as was described in connection with Fig. 1, for holding the stem in its upper and lower positions. When it is desired to reproduce a record, vthe member 22 may be telescoped, the record placed upon the turntable, and stem 11 then depressed to attenuate the air within theibellows member' 22 and create a suction through the pores of table 6. l
In the modification shown in Fig. 4,- an
-elastic member 23 is provided and is attached to the" under side of the table, its outer periphery being secured to the under surface of rim 1 and its inner periphery to the central portion Ltof the table adjacent to the spindle 9 of the talking machine. This member 23 may be formed of rubber or other suitable elastic material. It is maintained in its lower position by means of springs 27 which are connected at one end'to the under side of plate 7 and at their lower ends to the plate 28 placed within flexible member 23. ,Member 23 may be pressed upwardly by the fingers against the lower surface of plate 7 when the record is placed upon the table and the finger pressure upon member 23 released,I whereupon or secured to rim 1. Plunger 10 has connected therewith rod 112 which is ada ted to be connected to the motor of the tal 'ng machine in any desired way, plunger 10 thus constituting a continuously acting pump for exhausting the air continuously from beneath the record 2 during the reroduction of the same. Plunger 10 may be provided with an suitable valve means as 29 therethrough, t is valve opening when the plunger moves toward the record or toward the central spindle of the machine, and closing when it moves away from the record or the spindle to exhaust the air. The device shown in Fig. 6 is similar to that shown inFig. 3, different merely in the means provided for reciprocating member 23, this means comprising a U-shaped member 30 which is attached at its ends to plate 23 and extends upwardly through the central portion 4 of the record support above which it may be grasped to compress and expand the bellows member 22. Any desirable means may be used for holding the same in either upper or lower position. Also, the ring 31 is shown as placed upon the edge of sound record 2 to hold the latter firmly upon its support while the suction is being created.
