, To all whom it myconcem:

"Be it known that L JonAs W; AYLSWORTH, a citizen of the United States, residing at 223 Midlandaenue, East Orange, county of Emery-and State of New Jersey, have in- I vented ace'rtain new and useful Improve; U mentiin Apparatus for Making Duplicate Phonograph-Records of which the following is a description, 10 .gTli'isapplication is a division of Patent No.-85,5,553,.-grantedJune 4:, 1907. j 'I'In .Letters Patent, ,No.. 855,603, granted :June 4 1-1907,-I- describe an improved process andiapparatus for making duplicate phonog-raph records; in which a heated mold. is 1 srapldly:rotated-and a charge of molten material is supplied to. the mold, so as to be dis tributed:nni forinly over the bore, thereof vwhile inittfltiid eonditio nthereby driving 2?) any air orgas-bubbles. inwardly, after which 1 ;the'-mold. is rapidly cooled while being still irotated-so' as-Qto cause the material to set and rharden '-,,.My 'present ihvention relates to an improved apparatus of -the general type dis- 7 gelosed' in' saidapplication, but wherein provision is made whereby the material V of -whiehEtherecord-isto; be made may be in- ,a-trodixcedwithinthe. mold in a solid scondi- 4 tiongpreferablynin the form of a powder or smallgranules.

1 owing to the-ease .with #which-a definite compan'ying drawing, forming part of this specification, and in which Specification of Letters Patent. PatentQd NOV. 16., 1909- I Figure 1 is a longtiudinalsectional view of an apparatus constructed in accordance with my invention; Fig. 2, a sectional View on the line 2-2 of Fig. 1.; Fig. 3, a plan view, showingthe heating and cooling mechanism, and Fig. 4, an elevation of the coin plete mold.

In all of these views corresponding arts are represented by the same numeral; of reference. The base 1 is provided with frames 2-2,

in which are mounted theidler rollers 3-3,

for supporting themold 4. 5v is a driving roller for rotating the mold, said roller being carried in a swiveled bracket 6, operated by a handle 7, so that by skewing the roller 5 the mold will be moved longitudinally from itsengagement with the idler rollers 3-3, as I describe in said Patent No. 855,553. The driving roller .5 is rotated by a belt 8, engaging a pulley 9 and driven from a pulley 10.

The mold 4 is'of any suitable type, carrying as heretofore the representation in relief of a record on its bore, and is provided with the usual. flange 11, and with a remov .able flange 12, the latter, being held in place b a a e 1' birth ha i s" 4.-, I ,illustrate a gas burner. 13, for heating the mold, andfwater noizleislet forj' cooliiiglithe .s-ame Theigas burnenand' water nozzles e-s m rset? r r t e lb y' iqpera by a handle "16', so that either the burner or nozzles may be brought in pofsi I ca row the mold gto heat or cool the same; Flexible pipes fl,7.-. .l 8 withiva-lves 19- 20 convey gas or water-to the burner'l3 'or'noizles l tre speetively.

shaft 22, preferably square in cross-section,-

and having a trough 23 formed therein and arranged to reciprocate with respect to the receptacle. This shaft is mounted in independently rotatable bushings 2i, which permit the shaft to be turned" with respect to the receptacle when it is "desired to empty the charge of material intfo the mold. It will be obvious that by moving the shaft 22 to the right (Fig. 1) so as to withdraw the trough 23 within the receptacle 21, the trough will be filled with the powdered or granular material, so that when-the shaft is returned to the position shown in Fig. 1, a fixed. and definite charge of the material will be introduced within the mold. By now giving the shaft a half rotation, the charge of material will be deposited within the rapidly turning mold, so as to be uniformly. distributeqlover the bore of the same. By reason of the heated condition of the mold, the material will be quickly brought to a fluid state, in which condition it intimately engages the entire record surface, forcing any air or gas bubbles radially inward and taking a very perfect impression. During this operation, the gas burner 13, if used, is maintained beneatlr the mold, so as to keep the latter in a heated condition. After the impression has been takenand while the mold is still being rapidly rotated,

the handle 16 is operated sons to swing the water nozzles 14: beneath the mold, and the valve 20 is operated so as to cause jets of water to impinge against the mold and rapidly cool the same with its charge of mate rial. When the material has been thus set and hardened, the handle 7 is moved to skew the driving roller 5, and force the mold longitudinally from its engagement with the idler rollers, whereupon the operations described are repeated.

A suitable material for use in the opera tion of the apparatus described is that disclosed in my said Patent No. 7 82,37 5, dated February 14:, 1905, which material will be crushed or 'ground to a powdered or granular condition, after having been formed. Any other fusible material may, however, be employed, such forexainple, as asphalt, shellac compositions, and compounds of a similar nature. 7

It is possible'by the method disclosed to make very perfect duplicate records of materials that are so stringy and viscid when in a molten condition that they cannot be efi'ectively molded by existing processes, or whose melting point is so high asto make such processes undesirable.

Having now described my invention, what I claim as new and desire to secure by'lietters Patent is as follows:

1. Apparatus for making duplicate phonograph records, comprising in combination a hot tubular niold, means for rapidly rotating the same, means for introducing within the molda' charge of solid fusible material of definite quantity, and means for maintaining the heat of the mold until the record is formed, substantially as set forth.

5. Apparatus for making duplicate phonograph records, comprising in combination a hot tubular mold, means for supporting and rapidly rotating the same, a receptacle adjacent to the mold containing unfused fusilot his material, and means for transferring a measured charge of such material from said receptacle and depositing the same in the mold, substantially as set forth.
