halfljtone by a. single operation; Each' of these sharping fingersf16 is carried by a v I disk 17 mounted upon aspindle 18, as shown inliig. This spindle is provided with a cone-shaped bearing :19 fitting within a bearing opening in -the front action plate I '13, while the opposite end of'the spindlewis I p I vprovidedwith a reduced portion adapted rangement, however, necessitatedlta iconito fit within av hollow cap 20, which is in threaded engagement with an opening v in a the back action plate 14. 'The interiorof this f'hollow cap is provided with a small spiral :spring; which is adapted tobearma'gainst the end-of the spindle 18 thereby holding the cone bearing 1,9 firmly within the, coneshaped opening in the front action plate,
thuspreventing the sharping finger from f 1 rattling orzworkinggloose. The construc-" tion of this "cap and spring is; clearly shown-' in'the upper Dart o ga in connection links 22and arms '23; as clearlv. shownzin Fig. 1. Mounted upon one of the spindles 18 there is a pivotedaarm 24:to the opposite end of which is connected the link 25 which isconnected .toithe' arm 26 mounted upon I the spindle-21;, Thisspi-ndle is mounted in the front andfback actio'nplates in a man is clamped uponjthe spindle '21, and is provided with a pair-of lugs 29 and which engage with the ,pin 31 mounted upon the ner similarto the spindle 18; and carries theoperating handle 27. A splitcol'lar28 I the string 15, forcing the same Slightly out front action plate to limit the movementofi 'of the corresponding-spindles 18,.thereby operating the associated in each octave. v a As stated above, the movement of theopcrating lever is limited by meansof the stop sharping finger, one
fi-lugs'29 and 30. The lug 29 is so positioned that when it strikes the pin 81 the sharping' finger has been revolved from the position shown in dotted lines to the position shown in full lines in Fig. 5, so as to bear against ofalinement, and has reached a position bei low the center line or" the disk 17 In this positionthe sharping finger 16 is securely locked in place, as movement in one direction isprevented by means of the lug 29, while movement in the opposite direction is prevented by means ofthe tension of the string 15. This tension upon the string exerts i "mg 19 firmly n place and preventingthe force on the pin 16 acting toward the right (looking at Fig. 5), and in order for the finger 16 .to rotate back to its normal posi-' tion it would be necessary for it to [move slightly to theleft, owing to. the fact that it has revolved below the center .linezof the disk .17. It will thus be seen that I have devised a very simple "and efiicient means whereby the tension upon the string serves to The corresponding operating handles 27 are;
preferably grouped together upon the neck of the instrument within easy reach of the harpist. These operating handles are marked to designate the strings which they j control, and are grouped in a series corresponding to the usual sequence of the pedals of a pedal harp. That is, the operating handles referringto the strings they control would'be arranged in the order ofD, C, B, E, F, G, A. This is purely forconvenience, so that when one has learned the pedal series he can more readily learn to operate the.
levers. y In Figs. 6 to 9, I have shown a slightly.
modified form of my invention which .--is
adapted for use with a' single plate harp; that is, a harpof smaller size having but a single action plate. In this modification I omit all connecting links, it being necessary to operate each sharpingfinger individually. This makes the arrangement very simple, so thatthe sharping fingers can be applied to the small'inex'pensive harps.
sharping fingers areemployed.
' Th shaming finger 16 in h'ltl lOd of i 'mounted ona second'disk l7 on the spindle 18 This spindle is provided with a cone bearing'19 which fits within a cone shaped recess in the action plate; It will be notic'ed that thiscone bearing is beveledin the opposite direction from that shown in Figs. 1 .to
' 5, on account of'the fact that itis mounted 'on' the outside of the action plate instead ot the inside. The spindle18 passes through the neck 12 on the cylindrical opening in the neck, which opening is enlarged at 32. A
set-screw 37 engageswiththe inside of the spindle 18 thus locking the cap and spindle together, and thespring 3 5, presses outward" upon thecap 36, thus holding the cone bearspindle from rattling or working loose. -The disk 17 is provided with a lug 38 which ens gages with the arc-shaped slot 39in theac- The 'sharping fingers 16* bear against the stringsand in order to operate them it is merely necessary to press against the finger and rotate the same until the lug 38 reaohesthe end of the slot 39, in
which position the "sharping finger hasv reached a position below the center line" of the disk 17 wherebyitis automatically held 7 the manner described.
It'will thus beseen that I have devised a very simple and effective sharping finger,
which is automatically heldin operated position,
suggest themselves to anyone skilledin the art.
. Furthermore, while I have illustrated my.
inventionin connection with a harp, it will be readily understood that the sharping fin gers may be employed in connectionwith any form of stringed instrument in which What I claim as my invention is:
