MACHINE FOR SHAVING SOUND RECORDS 0R Specification of Letters Patent. Pgrtgmtzgfl Riga, 231$.- 51
Application filed June 22, 1911. Serial No. 834,808.
of Llewellyn Park, West Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful lmprovement in Machines for Shaving Sound Records or Blanks, of which the following is a description.
' My invention relates to machines-for sha ing sound records or blanks, particularly, but not exclusively, those of cylindrical form.
In shaving machines now in common use,
it is customary to provide a narrow knife for turning off the surface of the record or blank. This construction is ob ectionabl owing to the time consumed in turning off the surface and to the necessity for providing more or less complicated mechanism for feeding the knife along the record. Both of these objections are obviated by the employment of a knife extending throughout the length of the record or blank to be shaved,
as disclosed in United States Patent No. 57,314, granted to me on August 11, 1891.
One of the objects of my present invenion is to provide an improved device of this character which is simple, compact and ca pable of rapid and eliicient operation.
Other objects are to provide-a new and efficient shaving knife and improved means for feedingthe knife into the record or blank. p e
Further objects will appear more fully in the following specification and appended claims.
In order that my invention maybe better understood, attention is directed to the accompanying drawings forming part of this specification and in which Figure 1 represents a front elevation of a shaving machine embodying one form of my invention; Fig. 2 represents a cross section thereof taken on'the line 22 of Fig. 1; Fig. 3 represents a central longitudinal section of the record or blank support and its mounting; Fig. 4 represents'a plan view of a modified form of my lIlYQIltlOlltFlg.
represents an end view thereof partly in section on line 5--5 of Fig. 4; Fig. 6 represents end of which projects a standard 3, in thev upper end of which is rotatably mounted one end of the hollow core 4 of the mandrel 5 for supporting the record or blank 5'. Through the center of the core 4: extends ashaft or rod 6 tonne-end of which a crank 2" is secured by a set screw 8 or other suit able means. The opposite end of the shaft 6 is threaded as shown at 9 into the outer end of the mandrel 5, the core i being firmly held between the crank 7 and the conical portion 10 of tee mandrel. A check nut 11 locks the parts of the mandrel and shaft 6 in position. The core 4; preferably engages the shaft 6 only at one end thereof, the remainder of the central aperture therein being preferably formed of slightly greater diameter than the said shaft asshown at 12 in Fig. 3. In order to prevent slipping of the record or blank on the mandrel 5', the
- latter is formed with ribs 13 or is otherwise suitably roughened on the outer or record engaging surface thereof. By securing the crank 7 directly to the mandrel shaft, it is possible to rotate the mandrel withoutany lost motion such as is commonlyprodgced by reason of the employment of intercomnecting mechanism, such as belts,'between the driving means and the mandrel.
Rotatably mounted in the bearing 14- and in the bearing 15 projectin from the standard 3 is a. shaft or rod 16 adjacent the ends of which are secured the collars or bosses 1.7 and 18 on thelever 19.' It is, of course, understood that the lever 19 m ght be rotatably rjnounted on the rod 16. The lever has an arm 20 extending rearwardly under the mandrel and a downwardly directed arm 21.,
ion
a web adjacent the outer end of the arm .20. The web 25 is provided with a flange 25 extending substantiallyradially of the lnFig. 9, I ha ve shown a modified form of knife having theforward portion thereof mandrel 5, a knife 26 being clamped in po-' sitionon the said flange by the bar 27, which is held in position by means vof screws 28, or other suitable securing means, passing through apertures 9.9 in the knife 26 and threaded into the flange 25'. The openings-29 in the knife are preferably elongated transversely of the knife, as shown in Fig. 7, so as to permit adjustment of the knife relatively to the record surface.
prefer to form the knife with a large angleypreferably a right angle, between the surfaces forming the cutting edge thereof (see Fig. 8). rigidity than the sharp edged knives commonly employed and permits a cut to be taken the whole length of the record cylindo! without any chattering such as would occur if a knife with a small angle at the shaving edge were employed. This form also permits the employment of all four longitudinal edges of the knife for shaving.
ground on a curve 30. \Vhile this form of knife has given satisfactory results, I prefer to employ the form shown in Fig. 8.
One of the principal features of my invention isthe provision of means for automatically feeding the shaving knife into the record material. In the form of my invention shown in Figs. 1, 2 and 3, this means comprisesa spring 31 secured at one end to the reardownwardly extending wall of the frame 2 and connected at its other end to a pin 32 mounted at its ends in the sections 23 and 23 v of the arm 21 of the knife supporting lever. This spring is given such a tension as to feed the knife into the record material at a rate most suitable for elficient operation of the device. 7 In order to permit control of the movement of the le er 19 by pin or bearing 34 between the sections and 23' of thedownwardlv extending arm 21 of the lever. A rod 35 secured to the cam 33 serves as means to rotate the same. The cam being placed in engagement with the front downward extending wall 36 of the frame 2, the arm 33 may be rotated to cause the knife to be moved at will toward or away from the record or blank. The. extent of movement of the arm 35 regulates the amount of movement of the knife.
The numeral 37 represents a suitable receptacle adapted to be placed on the base 1 to receive the chips of shavings from the This form of knife has more record blank. One side of the said receptacle is of less height than the remaining sides and is formed at the upper edge with a bead 38, which is adapted to be placed under the inclined rib 3S) projecting from the adjacent end of the frame In the modified form of my invention shown in Figs. 4, 5 and 6, the base or support it) is provided with standards or legs t1, the topof the base being formed with an opening 1P2 through which the shavings from the record or blank are adapted to pass into the receptacle or drawer l3 placed under the base and movable between the legs thereof. Mounted in a bearing H: on the base or support is a shaft 45 which carries the mandrel 46 on which the record or blank to. be shaved is held. As in the modification hereinbefore described, the outer surface of the mandrel is ribbed so as to hold the redord or blank against slippin The free end of the mandrel is supported by an end; bearing 47 carried by a pivoted gate 48 in' the usual manner. A latch 49 adapted td engage the projection 50 on the gate 48 is pivotally mounted on the upright'5l formed at one end of the base or support. .Iiotatably mounted in the upright 51 and in the corresponding upright at the opposite end of the frame is a rod 53 to which the bosses 54 and 55 on the bell crank lever 56 are secured in any suitable manner, asby screws 57 and 58 respectively. The lever 56 is provided with an arm 59 extending under the mandrel, a knife 60 being adjustablysecured to said arm in the manner hereinbefore described. The other arm of the said lever extends forwardly and downwardly and is provided at-its lower end with a forked portion 61 within which the sector 62 is secured to the base or support by means of screws or other suitable fastening means 66, a washer 67 being inserted between the said spring and the base or support. In order to permit a regulation or adjustment of the pull or motive force of the spring (33 on the lever 56, I provide an adjusting device 68 bearing on the forward side of the spring and threaded into the base or support 40. this device being provided with an enlarged disk shape portion 69 for rotating the same. A cam 70 is mounted on the pivot 71 secured to the sector 62 and bears on the forward end of the base or support.40. By rotating the arm 72 secured to, the cam 70. the sector 62 and le- 1 ver 56 mav be moved either by or against the pull of the spring 63 to adjust the shaving knife relatively to the surface of the record or blank to be shaved. The spring is designed to feed the knife into the record 1 me as tact with the lower end of the leveras shown in Fig. 5 to the lower position. in contact with the support for the base 40. The curvature of the cam may be so regulated that by throwing the lever from one extreme position to another, a. cut of desired depth will be taken.
Itwill'be seen from the foregoing description that a shaving machine constructed in accordance therewith will be simple in construction. and rapid and efiicient in operation.
It is furthermore evident, that many modifications may be made in the specific structures shown and described Without departing from the spirit of my invention.
