it lnowu that ll, Finnen Consi APPL-noire. a citizen of the United States. residingv at lhilodelphia, in the county oif Philadelphia and State of PennsylwniiaE have invented certain new and useful linprovenients in Pbonogranis, ot' which the folletti is a speeicution. l
illy '-.u enion relates to cylindrical phonograine off inipiessible niuteriai such as eel luloid7 Xyionite or tile like material. and niy objeeito cheaply produee such phonograins troni sheet material and in which tbe united edges of the sheet run epproxiinately oircuinfei1` itially to eliminate the unpleasant kneel; ig sound caused by a stylus et iliing e. longitudinal joint during reproduction.
Hitberto phonograins have been tubular material and the s it has been found produce tubes gJive the des red iexibility. temple have' bee made to f use sheet ineierial with a. iep joint but such joint struct: the stylus squarely at right angles te the line oit inotion end caused a clicking or knocking sound it eaoli revolution of the record.
l attain iny objects end obviute the dill'.- culties in the manner illustrated in the accompenying;- drawing in Whieh igure l is a View of niy improved phonograni on a mandrel; Fig. 2 a cross sectional View of the structure of Fig. l; 3 o. View of the backing of my improved phonograni; Fig. 4E an end View of the strueture oi' Fig. 3,' llig. 5 a. View of the structure of Fig. 3 With the facing ribbon secured thereto; Fiff. 6 an end View of the structure of Fig. 5; Fig. 7 a4 View, partly in section, of a 1nodifled form of my improved phonogram; and Fig. S a view of a lapped joint tacing.
My improved phonogram comprises a ribbon of impressible material wound helieally with the edges either butting or slightly lapping. Before this ribbon is wound' into a helix the edges to be united are treated with a solvent or cement so they will be. firmly united.
In practice a baci-:ing sheet l is Wrapped about a substantially cylindrical form or core with its edges 2 and either .iuttingr or the latter torni the edges 'intent-ed Nov. 2, 19ml. Renewed iareh 29, 1908. Serial No. 486,531.
are preferably. beveled. ll he facing ribbon t is then wound iielieally around the bachingfus shown in Figs. and ti. Before this ribbon is wound onto the bucking the surfeces to be joined may be treated with a solvent or eeinentso that the backing and facing will be iimly;i1nited.
lily preferred material for both facing and .backing is Celluloid or Xylonite but any iinpressible sheet. material may be used. l find that aeeiones have the property of softening the materials named so that they bind or Weld together. As the aeetones do not dry out quickly ample time is ailorded for the various operations.
it is apparent that the edges of the facing strip d will4 touch or lap in the form of a helical line (3 running ironi end to end of the phonogram. If a. lapped joint is used the finishing process squeeze the soft material in such manner that the double thick ness caused by the lapping is completely obliterated. The bla-uli thus formed is then placed in a polished die and expanded therein under the combined influence of heat and pressure whereby the solvent or cement is driven ofi. The softened material is driven into intimate Contact with the die and When dry and hard has the high. polish of the die. As the material is compacted and Welded together along the helical line of union av substantially smooth and even outer surface is obtained. The sound record may nov.v be impressed on the blank thus produced by lany of the well liinown methods.
li: preferred Athe smooth polished die may be replaced by a sound matrix and the sound record impressed on the blank in the rst,
instance but I ind in practice that the best results 'are obtained by irst making the blanlr with a polished surface.
As shown in Fig. 7 the backing is in the forni of a ribbon Wound in a direction opposite to that of the facing. l
A. bar-.hing of Cheap, course Celluloid. may be employed and the facing strip may be, and preferably is, aA thin ribbon of iine Celluloid. To secure the best results the faeing should be of such Width that only a single joint is crossed by the stylus on each revolution. As the line. of union of the edges of the facing ribbon is helical it runs approximately circuinlerentially when it passes under the stylus and does not een@ eel E semen the knocking sound that e jbint. striking the stylus transversely does.
By the useof tnin sheet material the ph nogrems may be materially thinner than those made of seamless tubing and consequently more flexible. Records mede in accordance With my invention also run true when in use Aas they are of uniform thickness throughout.
In use the phonogram is placed on e man- Adrel sleeve 7 of any desired type which is placed on the talking machine mandrel 8. It is then played like an ordinary cylinder record..
I claim 1. A cylindrical phonogram comprising n strip or ribbon of impressible material wound into a helix and having its edges united.
2. A. cylindrical phonograni of impressie-l ble materiel comprising a backingsheejt" vand Wound helically into e tube and e facing strip Wound helicaily in the opposite'direction and secured on the backing withffthe edges unitede 5. A. cylindrical phonogram comprising a strip or ribbon of impressible material wound into a helix with its edges united and a sound record on the outer face thereof.
6. A. cylindrical phonogram comprisin a backing sheet and a facing of impressi le materiel helieally secured thereon with its edges united and a sound record on the outer face thereof.
7. ,A cylindrical phonogram comprising e backing sheetl of coarse material, a facing ribbon of fine impressibl material helically secured thereon with its edges united and ail sound record on the outer face thereof.
8. A cylindrical phonogram of impressible material comprising :iy backing strip -Wound vlielically into a tube and a facing strip Wound-"-helically in the o posite direction and secured to the backmg with the edges united and a sound record on the outer face thereof.
In testimony whereof Liliave aliixed my signature in presence of two witnesses.
