Be it known that I, JOHN A. Soweit., a citizen of the United States,l residing fat Sacramento, in the county of Sacramento, State of California, have invented certain new `and useful Improvements in Circle- Line-Wave Double Disk Records for Soundscription of the same, reference being had to the accompanying drawings, 'and to the ,characters of reference marked thereon,
' which f orm a part of this application.
. This in vention relates' to. improvements in double disk records for sound producing machines, the object ofthe inventionbeing 4 to produce a record which will carry a greater number of impression lines vto a given diameter than the disks now commonly used'.
tion. Also by reason of these waves the impression lines are relatively longer than they would be on flat surface and hence a greater number can be placed on a record 'of a given diameter than on the now commonly used yfiat records. The invention also embodies certain other advantageous features which will hereinafter appear.
A still further object of the invention "is to produce a simple andy inexpensive device and yet one which will be exceedingly et'- fective for the purposesfor which it is designed. l i
These objects I accomplish by means of such structure and relativel arrangement of parts as willfully appear by Va perusal of the following specification and claims.
In the drawings similar characters of reference indicate correspondingparts in the several views.
Figure l is a top plan view of my improved record..
A further aim of the invention tenso' construct the record that -it will allow oi a Spcification of Letters Ifateiit. i' Patented Nv, 20, -E Application aiea mmh 8,1916. serial No. 82,926. Y 'v I Fig. Eis a. sectional view taken onl'a line X-X of Fig.' l and twice enlarged.
Fig. 3 isanfedge view ,of the recordasi-f' shownin11`ig-1.A Referring now more; particularly jto the characters off-"reference o n the. drawings,
'the record is made up primarily of afstilljening plate 1 whi'clrmay 'be of metaljoi" o i'er if l` suitable material provided with a plurality of holes theconiposition of' the record proper beingmoldedv over ythe metal plate l and through the said holes2 to forma 'conil posite member, the said metal plate being'so lif formed as'to follow the general shape offthe composite record a hei-cina fterV set forth: 1 i 2 p ity of radial Waves 3, the valleys of wliicliyasait The record-itself is formed into a pluri 3a, have a slightinclination upward from '521.
theoutrzedge of the record inwardlyto; the inner limit of' the :sound ,impression lines, at {Il} 3b. 'l I j f d The sound` impression lines 4 are made in la spiral lineand due tothe` radialfwaves a greater length of this line can be had on a record of a given diameter than records now commonly in use. By reason of the inclination of the valleys 3'", and the sloping of the hills upwardly from the valleys, the sound producing needle in traveling over the record works gradually uphill causing it to have perfect frictional engagement at all'times with the record' thus allowing of the greatest Y eiiiciency in the sound production. The metal plate formed Within the material" of the composite record is shaped to' conform to the radial Waves described above and by reason of this metal plate heilig so centrally located` within the record, and also having these radiall Waves, this causes the same to forma stiffener and reinforcement forl the record so that it .Will not be subject to cracking or warping in hotweati'er and will be much more d urable andy less liable t0 breakage than the now commonly constructed records.
In addition to the greater efficiency in sound production which can be had with the use ofm'y improved record due to the uphill climb oi the needleas indicated above, the record will also allow of' a much stronger volume of sound production due tothe fact thatsinee l will have' space fora greater length-of linethan the ordinary record l can provide a greater strength of material between each convolution of the line and still allovv of a musical composition of more than 4the usual length beingplaced upon a record of given diameter. i
The hills of the waves on each side of the disk lie Hush with the center or hub portion of .the disk, whereby the hills will all lie Hush on the revolving plate 1orv disk of the y sound producing machine so as to'hold the record in the proper horizontal position. The record of course has acentral opening 5 to 'fit over the receiving pin on the revolving plate or disk.
From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of l the invention as set forth herein.
comprising a circular disk having its recordy While this vspecification sets forth in detail the present andpreferred construction of the device, still in practice .such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.
Having thus described my invention what I. claim as new and useful and desire to secure by Letters Patent is:
l. A record for sound producing machines surface formed into radial waves, as described. i
2. A record for sound producing machines comprising a circular disk having its. record surface formed into radial Waves, the valleys of 'the waves inclining upwardly'from their outer to their inner edges, as described.
3. A record. for sound producing machines comprising a circular disk having its record 5. Asound reproducing record having a ,I
surface provided With'portions which extend' upwardly and downwardly from other portions thereof,` and having a record groove extending over the said portions.
6. A sound-reproducing record having a surface provided with connected portions which extend upwardly and downwardly in4 alternate succession, and having a record groove extending over the said portions.
7. A sound reproducing record having an undulating surface, and having a record groove extending over said surface.
8. A sound-reproducing record having a surface provided :with a circular series of connected undulations, and having a record groove extending over the undulations of said surface.
9. A sound-reproducing record having a Surface provided with a circular series of connected undulations radiating from the axis thereoand having a record groove extending over the undulations of said surface.
In testimony whereof I aiiix my signature.
JOHN A. SOWELL.
