To all whom it may concern.'

Be it known that we, BmAN F. Primror, a citizen of the United States, and a resident of Orange. in the county of Essex and State ofNew Jersey, and HERBERT A. COOK, a citizen of the United States, and a resident of East Orange, inthe'county of Essex and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Manufacturing Phonograph-Records, of which the following is a description.

Our invention relates to apparatus for manufacturing phonograph records, and more particularly to apparatus whereby a record shell may be provided with a backing suitable for supporting the record on a phonograph mandrel or other record sup- I Extending vertlcally upward from the rear.

ort. p The principal object of the invention is to provide improved means for facilitating the formation of the shell. Y

A further object of the invention is to provide means forprotecting the outer surface of the record shell from the deposit thereon of the backing material during the forma-l tion of the backing.

Other objects of the invention will appear more fully in the following specification and appended claims. T

In order that our invention may be 4more clearly understood, attention is herebyA directed to the accompanying drawings forming a part of this specification and in'which;

Figure 1 is a view partly in side elevation and partly in section of apparatus embodying the preferred form of the invention and arranged with the parts in position for the introduction of the backing material within the record shell; Figs. 2 and 3 are views in section taken respectively on the lines 2-2 and 3-3 of Fig. 1. Figs. 4 and 5 are fragmentary views similar to 4that 'of Fig. 1 showing the apparatus with the parts in different Irelative positions to be hereinafter more fully described; Fig. 6 is a view simi'- lar to -that of Fig. 1 showing the apparatus with the parts in still another' position Fig. 7 is a view -in section taken on the line 7 7 of Fig. 6; and Fig. l8 is adetail view in verbacking within the record' tical section showing a portion of the record 1n position on its support.

In all of the views like parts are designated by the same reference numerals.

Referring to the drawings, the numeral 1 rests upon the top of the .memberl and is `provided with a portion secured within the upper portion of the opening2. `The cen- .l tral opening4 through the member 3 'is in vertical alinementrwith the opening 2. A

portion of the base 1 is the standard 6. This standard, as sho'wn,l is in the form of a pipe being secured to the latter, as byl a pin 7..

' With this construction, the basel is adapted `as by a pin 10, projects-forwardly from the 80l said standard at a suitable distance above the base 1. .The forward portion ofthe arm "8 is also formed with a tubular portion, as

shown at 11, which tubular portion is adapted to` form` a guide for a vertical rod 12 on the lower portion of which is secured a core 13 of circular cross section tapering linwardly from the upper to the lower end thereof. -The sleeve 11, rod 12, mandrel /r core 13, as well as the openings 2 and 4 are in axial alinement with each other and the diameter of the opening 4 is 'such that when the core 13 is in operative position for theintroduction of the backing material within the record shell 14, as shown in Fig. 1, the lower portion of the core 13 will' completely close the opening 4 and together with the ange 5 prevent the escape ofthe backing I material from the lower end of the record.

designates a'base which is provided with a f vertical opening 2. An annular member 3f and extends through and below the base 1,

disclosed and claimed in an application of Thomas A. Edison, Serial N o. 672,397, filed January 20, 1912 and is not a part of the presentinvention. The outerecelluloid shell 14 is shown at 15 as provided with a thin coating of rubber or other suitable yielding resilient material within whichis formed a plaster backing 16. Thecelluloid shell is formed at its ends with inwardly directed flanges 17 and 18, the lower flange 17 being formed with a longitudinally extending portion 17 which is adapted to fit closely about the fiange 5, as clearly shown in Fig. 8, whereby the record shell may bel supported at its lower end in axial alinement with the core 13. The upper flange 18 is of such inner diameter as to extend into proximity to the core 13 but not to contact ,-the

, formed of plaster of Paris or the like. The

provision of a slight space between the Harige 18 and ycore permits the escape of air from within the record shell when the' backing material is being introduced into 'l Y the latter.

To protect the outer surface of the record shell against the deposit thereon of the backing material, we preferably provide a guard 21,v which may be in the form of an apron resting upon the upper portion of the record shell and extendingloutwardly and downwardly from the latter. rIhe guard 21 is formed with an inclined conical surface 21 lwhich is adapted to engage the edge of the record shell between the outer cylindrical surface thereof and the flange 18, to center the upper portion-of the said shell. By means of the flange 5 on the base 1 and the guard 21 the record shell is accordingly firmly held in aXial alinement with the core 13 and the inner surface of the backing is thus formed true or coaxial with the outer surface lof the record. The apron 21 may be supported by vertical rods y 22 secured to'and projecting .from the lower surface of a flange 23 formed on a collar 23 which is slidably mounted on the rod 12. The said apron is provided with a cen-l 4'tral opening 21 whereby` the core 13 may be moved through the same, the guard 21 being adapted to be supported when the cor'e is in a raised position or when there 1n Figa is no record shell in position on the apparatus, by the engagement of the collar 23 with the upper `surface of the core.

To permit an leasy manual reciprocation of the rod 12, We preferably pivot to the upperend of the rod 12, as at 24, an operating lever 25, this lever beingpivoted 'at its rear end, as at 26, to the upper end of a link 27, which latter is pivoted at its lower end, as at 28, between ears projecting rearwardly from the arin 8. rIhe forward portion of the lever 25 is preferably forked, as shown at 29, a handle 30 extending across the forked portion to facilitate the convenient operation thereof. fn order to permit the rod 12 and the core 13 supported thereby to be conveniently held or supported at a proper elevation, we provide a catch 31 pivoted between outstanding ears 32 at the front of sleeve 11. The catch 31, as shown, is provided with a locking nose. 33 which is yieldingly pressed into engagement with the rod 12, as by a spring 34, and also with a flat thumb piece 35 for operating the atch to disengage the nose 33 from the rod 12. rlhe elevation at which the rod 12 and the core 13 are held by the latch 31 isdetermined by notches 36, 37 and 38 at different elevations in the rod 12. A. projection 39 extends laterally from the rod 12 and is adapted to rest upon the upper portion of the sleeve 11 to support the rod 12 and core 13 in their lowermost positions, as shown in Fig 1.

To lock the guard in engagement with the upper surface of the record, I provide an arm 40 pivoted on the standard 6 and held against longitudinal movement on the latter by collars 41 engaging the upper and lower surfaces of the said arm, these collars beingheld in position as by set screws 42. The arm 40 is provided at its outer end with a hook shaped portion 43 adapted to surround the rod 12 land to engage the upper surface o'f the part 23, as shown in Fig. l.1, when it is desired to lock the guard in engagement with the top of the record shell. A projection 44 extends from the upper part of the arm 40 and is adapted to engage the under surface of the flange 23, as shown in Figs. 6 and 7, to support the guard in elevated the core 13. i

In operating the apparatus hereinbefore described, the catch 31 is released and the lever 25 operated until the notch 37 in the rod 12 is brought in position to be engaged by the locking nose 33 (see.Fig. 6). When the parts are in this position, the pressure position independently of 3o stated, the lower portion of under the iiange cylinder 14 before shown in Fig. 5, so readily detached from 'suitable means so as v36, the object of -25 operated to bring the catch vupper portion of the 23 to support the guard 21 in an elevated position entirely vabove the core`13, as shown in Fig. 6. 7With the parts in this position unobstructed access may be had to the core 13; and the latter may begreased with crude oil or any other to prevent the plaster of Paris'or other backing material from adhering thereto .during the subsequentop'- erations. The parts are next adjusted to the position in whichv the vcatch 31 engages the notch 38 and the collar 23 rests upon the upper portion of the core 13, both of these parts being thereby sufficiently elevated to permit the placing of a record shell in position on the supportingrmg 3. For

a record such as herein disclosed, the rubber film 15 is formed upon the celluloid the same is placed in positlonon the said ring. With the record shellin place', the` parts are arranged in the position shown in Fig. 1, in which the pro- Jection 39 engages the upper portion of. the sleeve 11, lthe guard apron 21 being in' engagement with the upper portion of the record and being. held in position on the latter by .the engagement of the part 43 of the arm 40 with the uppersurface Vof the part 23. In this position, as hereinbefore the record shell 1s completely closed by the core v13 and flange 5 "so that the'record material may be mtroduced as shown in Fig. 1 into the space Within the record shell 14 and around the core 13. After a. suflicient amount of backing material has been introduced within the record shell, vthe rod 12 and core 13 are elevated until the catch 31 enga ges the notch this operation being to raise -the notch 19 in the core above the record so as to prevent the formation of a rib on `the backing when the latter hardens, the core, however, still extending throughout the length of the record shell. With the parts in the position last described, the

support on a record mandrel. after whichy the core is lifted out of the backed up record shell.. During the initial portion of this lifting operation the guard 21 is held firmly in engagement with the top of the record and holds the latter firmly in position, as that the co're -i's verv the backing. To lift the core completely out of the record. the arm 4.()y is swungto one side and .the lever 31 into engagement with the notch 38. During this operation the collar 23 is engaged by the core and the guard the record. the

21 is lifted The latter may now above the top of be removed from vaxially within said body portion ,of the core last named means backing apparatus herein disclosed, and completely dried in an oven, reamed, an inishedup in any suitable manner.

lVhile we have described the preferred form of our invention, numerous changes may be made therein without departing from the spirit thereof; and we wish, therefore, not to be limited to the exact details herein disclosed.
