instrument equipped with a needle-sh. rpeni'ng device constructed in accordance with the invention. a
Fig. --6 is a top plan view of the same. My said device comprises a base plate A equipped with an inclined standard '13 prefcrably cast integral therewith and providcd at its upper end with a flange G extending at right angles to the standard B and at an incline to the base plate A. Mounted on the latter is a cup bearing D which receives the ball E at ihe lower end a shaft l which carries a sleeve G preferably ofrubber or similar yielding materiel projecting at one end beyond the upper end of said slmit. The said sleeve G is irovidcd in its lower end with an annular groove H receiving the upper end portion of a helical spring I which is secured to the upper end portion of the cup bearing D. The connection between the latter and the ball E is such as to "orovide a universal joint between the shaft and said cup Re iho'rably mounted upon the upper end of he shaft 35 and within the upper end porion f the sleeve G is the stein'J of a hollow cone K which is provided interiorly with a grinding surface L containing carborundurn, emery or other well-lmown grinding material. The spring I normally supports the shaft'F in axial. a-Iinement with the inclined axis of the cup-bearing D and substantially.
urallel with the standard B.
We flange is provided with a slot M teii'riallyt in axial alinement axis Oi the cup'bearing D ch the needle to be sharp- 1 into the hollow manually held --3-, or the ready means of liol iug ihe needle in proper position in the ling in it e flange C and arojecting into i i sound box of the uEllCi hollow cone K. .Prefe1'sbly a,
the portion of the needle projecting through the slot M, a nd which, when said. lever O is turned on its pivot in one direction, is forced 0'5 lowicono equipped with an interior tapered by the walls of the arcuate slot-Q, into firm engagement with the inner end wall of the slot M. A spring R engaged with said lever 0 serves to hold the same normally in the position shown in Fig. l to engage the needle and press it against the inner end wall of the slot M.
In operation a needle is positioned substantially as shown in Fig. -3-, and the hollow cone K is then manually rotated witha gyratory motion while maintaining the inner surface of the lining L in contact with the needle point; this gyratory rotation being readily accom lished against the slight resistance odere by the spring I and serving obviously to cause the needle point to die-ground equally on all sides so as to give the same a true, or substantially true, new conical point. A single revolution of the hollow cone K is usually all that is re quired to again place a needle in condition for use in the instrument.
As shown in Figs. -5- and -6 the said plate A is secured upon the top plate of the casing or housing of the sound-reproducing mechanism of a phonograph, and contiguous to the rotatable disk adapted to contain the record and within the are through which the needle carried by the sound box is adapted to be swung upon turning the horn carrying the soundbox pivotallyyth'e slot M being accurately positioned to lie in the path of the needleso as .Eto receive the same and the angle of inclination'of the standard B and ange G being-such as to accord with the inclination of the needle when disposed in operative position relatively to the record. The normal axis of the grindin element is similarly positioned to accord with the. inclination/of the needle so that, when it is desired to grind the'needle it is only necessary to swing the horn of the instrument until the needle enters the slot 'M 'of the flange G, and by swinging the lever-O against the action of the spring R, allowin the needle to engage the inner end wallof saidslot M. The lever 0 is then released and the'hollow cone Ksprungoverthe needle point so that the latter projects into the same. The cone K is nowv rotated with -a.,.gyratory motion about the needle point as an axis while maintaining'the surface L in contact therewith.
Wh le I have shown the -preferred em bodiment of my invention in the accompanying drawing, it will be obvious, of. course, that the same may be otherwise embodied without departing from the invention as de fined in the appended claims.
Iclaim as my invention:
1. A needle point grinder including a holequipped with a pivoted carrier and'a.
' operable means for holding the needle engaged in sa d recess, and a grinding element-i grinding surface, and a flexible support for ilXls of'said hollow cone and coincident with that of a needle point projecting into the same and maintained in contact with the interior surface of said cup as the latter is gyrated, in combination with means for. rigidly supporting a needle normally posi= tioned in axial alinement with said hollow cone.
3. In a sound-reproducing machine sound box equipped with needle-engaging means mounted on said carrier, needlepoint grinding means mounted on a rigid art of the instrument and including a rigid ele ment having a recess disposed in the path of and adapted to receive a' needle held in said needleengaging means of said soundbox for accurately positioning'said needle with respect to a grinding element, ands. grinding element associated with said recessed element adapted to be manually gyrated about the axis of said needle while maintained in surface contact therewith.
4.
