MACHINE FOR SHAYING SOUND-RECORDS.

speciaeation of Letters Patent.

Patented Mar. 7, i916.

Application led June 21, 1913. Serial No'. 775,028.v

T0 all t0/0m it may concern Be it known that I, CHARLES SoiiiFFL,a citizen of the United States, and a resident of Montclair, Essex county, New Jersey, have vinvented certain new and useful Improvements in Machines for Shaving Sound- Records, of whichthe following is a description.

My invention relates to machines for shaving sound records when itis desired to remove the outer portion of a sound record tablet in which the record is impressed' in .order that a fresh surfacemay be presentedy to be recorded upon, and more particularly in a patent to John Ott, No.- 796.857, dated' August 8, 1905. and in an application of Frank E. Traphagen, Serial No; 592,976, filed November 18,1910, and entitled Shaving knife for sound records.

difficulty has been experienced in readily effecting an adiustment of the shaving knife to secure the proper cut, that is, a cut that is neither too deep nor too shallow.

' The principal object of mv invention is to obviate this objection, and in accordance with this object I provide -in a machine of this type, an improved construction wherebv, regardless of ythe amount of materialv whieh'has previously been shaved from a record for which the machine is adapted. a

In machines lof this character heretofore employed. much l carrying the shaving mechanism My invention also contemplates the provision of a device in the form of an attachnient adapted to be readily applied to shaving machines in use for accomplishing the above results.

4 *Further objects and features of my invention will appear more fully in the following description and appended claims'. In order that my'invention may be more clearly understood, attention is hereby dir4 iected to the accompanying drawings, foi'ming part of --thisspecification, vand in which:

I1 igure 1 is a side elevation, partly in section, 0f a record shaving machine in accord-I ance with my invention with the shaving knife in inoperative position. Fig. 2 is a fragmentary view similar to Fig. 1 with the vshaving knife locked in operative position. Fig. 3 is an enlarged sectional view on line 3-3 of Fig. 1, parts being shown in elevation. Fig. 1 is an enlarged'sectional view on line 4 4 of Fig. 3, a part being omitted; and Fig. 5 A section, showing the connection between the actuating hell crank lever and the mounting therefor.

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

Referring to the drawing, 1 represents the frame of the shaving machine having a mandrel 2 for supporting the record 3 to be shaved, and also having an arm or carriage Carriage L is slidahly mounted on the usual back rod 6 and the straight edge 7 and is adapted to' be moved longitudinallv of the record by the feed screw l8 cooperating with the usual feed nut 9 carried by spring support 10, which support is secured to the arm or carriage 4 in thelmanner common to machines of this type.

Referring especiall)v to Figs. 8 to th'e shaving device comprises a supporting member 11 which carries the shaving knife and thev mechanism for effecting movement of the latter info andout of operative po sition and for locking thc same in operative position. The Suppen-ting member 11 is preferably rectangular in shape and is suitably secured to a projection v1Q formed on .carri-.age 1, as by screw bolts 13, with one of its flat sides in engagement with a flat surface formed on projection 12. The

is a fragmentary view, partly iir' iiat side of support 11 adjacent" projectionv shaving knife. Bar 15 is preferably rectangular in cross section and ii'ts closely in its A guideway. A member 16 provided with va 1eY sapphire, 1s mounted 1n the lowerv end of bar in an-y suitable manner. l1`he upper suitable cutting tool 17, preferably `of end portion of bar 15 is provided with a longitudinally extending recess 18 in the lower portion of which is seated a. spring 19, and in the upper portion of which is slidably mounted a rod 20, the lower end of the rod 2O engaging spring 19, whereby a resilient connection is provided between bar 15 and rod 20. ln order to limit the movement of rod 20 with respect to bar l5 I provide rod 20'A with .a longitudinally extending slot 21 through which passes a pin 21 secured to bar 15. The upper endof rod 20 is screw threaded and passes loosely. through an aperture provided in a right-angled extension 22 of a pla-te 23, being adjustably secured to this extension by means of the lock nuts 24. `A strong coiled spring 25, seated at one end in a recess 26, provided in support 11, and bearing at its other end against the under side of extension 22, serves to constantly exert a force tending to so move member 23 and rod 20 as tohold the shaving knife in. retracted or inoperative position, as shown in `lfig. 3. A stud 27 secured to extension 22 and aboutwhich the upper end of spring 25 engages, prevents lateral movement of the latter with respect to the extension. Member 23 is providedl with a pair of aligned slots 28 and 29, and is slidably mounted on that side of member 11 opposite the side in which .groove 14 is formed, by means of a screw 30, screwed into support 11 and formed between its head' and screw threaded end portion with a Smooth cylindrical portion 31 which ts in slot 28, and a cylindrical hollow bearing piece' or collar 32 suitably secured to support 11 and provided with a portion extending beyond support `11 and fitting in slot 29. The end of member 23 opposite the .right angled extension 22 is provided wvith an enlargement 33 in which is formed an irregular slot 34, the lower and upper portions of which are formed on different curves. In order to control the movements of member 23 and thereby those of the shavingknife, I provide suitable actuating means, preferably a pivotally .mounted bell crank lever one arm of which is provided with a'handle 3G and the other arm of which is provided with a pin 37 fitting in slot 34 of plate 23. Bell crank lever 35 is provided at the anglethereof with an irregular aperture in which is received a similarly shaped portion 38 formed ona bearing member 39, as shown in Figs. 4 and 5, whereby relative rotary movement of bell crank 35 and member 39 is prevented. Bearing member 39 has a preferably left handed screw threaded connection with the-interior of the hollow bearing piece or collar 32 secured to support 11 and serves as a pivotal mounting for bell crank 35. Member 39 is provided with an opening therethrough, the major portion of which is screw` threaded and the inner portion of which is formed with an enlargement 40 having a smooth bore. Reference character 41 represents a screw engaging the threaded portion of the opening enlarged portion 40. Screw 41' is provided with a reduced portion 42 at its inner end, on'which is-loosely mounted a cylindrical cap 43 which fits closely in the enlarged portion 40 of the opening through member 39. Bell crank lever35 is suitably secured on member 39 against a flange 44 formed on the latter, as by meansof washer 45 and nut 46 on screw 41. Support 11 is provided with a recessr'47 of sufficient size to permit members 32 and 43 to be positioned as shown in Fig. 3 in assembling the shaving device.

Obviously the turning of bell crank lever 35 will, by reason of the screw threaded connection between the fixed hollow bearing piece 32 and member 39, resultin a movement of translation of lparts 35, 39, 41 and 43 toward or from the shaving knife, according to whether lever-35 is turned to the left or the right. Portion 34 of slot 34 is Aso shaped that any movement of .pin 37 therein will'exert a cam action on plate 23 to cause sliding movement thereof on support 11, while portion 34 of slot 34 is formed on an arc which, when the pin 37 is in engagement therewith. is concentric with the pivotall laxis of bell crank 35, whereby movement of as follows: iVith the parts shown inthe position of F ig. 1, on turning bell crank 35 to the left, pin 37 will exert, by means of its .engagement with portion 34 of slot 34, a

cam action on member, 23 to slide the latter on support 11v against the action of spring 25. This movementof member 23 causes rod 20, by reason of its connection with the shaving knife, to move the latter to a position in Vwhich the cutting tool 17 thereof engages the record As soon as the cutting tool engages the record,f.1rther movement of the bell crank 35 to the left and thereby of member 23 and rod 20 toward the record will tend to project the cutting tool linto the record material.l The resistance offeredby y the record materiall to the projection of the cutting tool thereinto, however, will cause relative movement of rod 20-and the shaving knife and thereby the compression of spring 19, with the result that by the time pin 37.

has reached the end of portion 34 of slot 34 the cutting tool will be projected into the record in aterial only a short distance and a distance proper for securing thevdesired cut.v Spring 19 is made comparatively lon-g and quite weak, and the distance the cutting tool will be projected into 'any record for which the machine .is adapted will, therefore, be substantially uniform vregardless of the thickness of the record. When the pin 37 is at the end of portion 34v of slot 34, the upper ends of slots 28 and 29 of member 23 will be in engagement with screw 30 and collar 32 respectively, and further' sliding movement of member 23 toward lthe record will be prevented. As lever 35 is turned still farther to the left, pin 37 will enter portion 3f of slot 34, and as this portion 34 will then be concentric with .the

pivotal axis of the bell crank, the continued movement of the bell crank to the left will merely act to effect the locking of the shaving knife in operative position. The locking of the knife results from the movement of translation imparted to members 39, 11

and 43 on pivotal movement of the bell crank lever 35 by reason of the screw threaded connection between member 39, secured to the bell crank. and the fixed collar 32, screw 41 being so adjusted in member 39 that capA 43 will be forced linto locking enga-gement `with bar 15 of the shaving knife only duringthe latter part of the movement of the bell crank in portion 34 of slot 34. When pin 37 has reached the lower en-d of slot 34:, cap 43 will have been moved to such a p osition as to lock the bar 15 firmly against projection'lQ of the carriage 4. Itwill also be apparent` from an inspection of Fig. 2, that when pin 3T is at the lower end of slotr 34 it will also be below the dead center position determined by a line through 'the end of the cutting tool 17 and the pivotal axis' ofthe bell crank lever whereby the.. parts will be locked against displacement in the posit-ions shown in. this figure. The turn-l ing of bell crank to the right, from the position shown in Fig. 2, will first'effect the movement of member 39 away from bar 15 of the 'shaving knife andI thereby the release of the latter, whereupon spring 25, as soon as pin 3T is'moved above dead-center position and has entered portion 34e of slot 34,will quickly act to automatically effect the return of the parts to the positions shown in Fig. l and thereby the withdrawal of the shaving knife from operative position.

It will be obvious that support 11 together with the shaving knife and the mechanism carried. by support 11 for effectingl an'd controlling the movements of the shaving knife and the locking of the same in operative position, may be made as an -at- Vtachnrient, which may be readily applied to shaving machines now in use 0r to phonographs to adapt the same for shaving 4 from the spirit of my invention and the p scope of the appended claims.
