TUNING PEG FOR STRINGED MUSICAL INSTRUMENTS.
Application filed October 7, 1924.
My invention relates to improvements in tuning pegs for stringed musical instruments.
The invent-ion relates more particularly to that type of peg which includes a shank re ceived in a suitable opening in the peg head, a button or knob by which the shank is turned, and a cup member embracing a part of the shank with one end of the cup engaging the peg head and the other end of the cup engaging the button. The principal object of the invention is to provide for etlective engagement of the cup and button and I accomplish this object byserrating that edge of the cup which engages the button whereby the serrations will penetrate the relatively soft material of which the button is usually made and produce an effective interlocking of the parts.
The invention is illustratively exemplilied in the accompanying drawing, in which Figure 1 is a sectional view of a part of a peg head showing my improved tuning peg in elevation and in operative position. Figure 2 is a substantially longitudinal sectional view of the peg taken on lines 2-2 of Figure 1; Figure 3 is a substantially transverse sectional view taken on line 33 of Figure 1; Figure 1 is a transverse sectional view through the button and shank and taken on line H of Figure 2; and Figure 5 is a view of a slightly modi lied form of my invention.
teferring to the drawings and particular- .ly to Figures 1 to 4: inclusive, the tuning peg comprises a shank which operates in an opening 11 in the peg head 12 of an instrument. The shank 10 is constructed of one piece of material and has a shoulder or enlargen'ient 13 which is greater in diameter than the opening 11 in the peg-head 12, and which is tapered off on its under side to frictionally engage the walls of the opening 11. Above the shoulder 13 the shank is provided with an extension 1 1 having the usual hole 15 for receiving the end of a string. Below the tapered portion of the shoulder 13 the shank is of uniform diameter to loosely lit the opening 11, and at a point substantially below the under face of the peg head 12 the shank is reduced in cross section and squared all the way to the end, the squared section designated 10, being provided with a threaded axial bore 13 projecting substantially throughout its length.
A button 17 having the usual broached square hole 18 is mounted on the square section 10 and a screw 19 having its head seated. against the crown of the button is adjustable Serial No. 742,102.
at its opposite end in the threaded bore 16 of the shank.
Mounted on the round section of the shank projecting below the peg head 12 and between the latter and the butt end of the button 17 is a sleeve 20 which comprises a metal cylindrical member having a cone-shaped end 21 adapted to seat in and frictionallv engage the wall of a counter-sunk section 22bit the opening 11 at the under face of the peg head The opposite or lower end of the sleeve :20 projects over the square section 10 and is provided with a serrated surface 20 adapted to bite in the adjacent butt end of the button 17 when the screw 19 is tightened to telescope the sleeve over the shank and into frictional engagement with the intermediate section of the peg head 12.
It will be clear that the present construction permits the serrated surface 20 of the sleeve 20 to bite in the soft celluloid, rubber or bone material from which the button is gen.- erally made and that after proper setting of the screw 19 the tuning peg virtually becomes an integral member provided with oppositely projecting tapered surfaces, which maintain a constant relation to each other and to the walls of the tapered portions of the opening 11 in the peg head. This coi'istruction altords a great saving in manufacture due to avoiding the step which consists of broa chin g a square hole in the sleeve and then squaring the shank to fit the same, a process which is general in tuning peg manufacture. The invention also does away with all lost motion when the peg is being adjusted to turn a string, because of the fact as already stated, that it becomes an integral unit all the elements of which move together.
In Figure 5, I have shown a slightly modified embodiment of my invention which con sists in providing a washer 23, having one surface thereof serrated, and the other provided with lugs 24 which are adapted to lock in slots 25 disposed radially in the under surface of the sleeve 20, the slots being substituted for the serrations of the preferred form. The washer 23 is placed betwen the sleeve 20 and button 17 so that as the screw 19 is tightened the button washer, sleeve, and shank become as one unit in the manner already described.
lVhat I claim is l. A tuning peg for stringed musical. instruments, comprising a shank, and cooperating members therefor, comprising a sleeve provided with serrations, and a button of softer material than the sleeve the serrations thereof biting into the button to present a nonslip relation between the sleeve and button.
2. A tuning peg for stringed musical instruments, comprising a shank, friction means carried by the shank and having a serrated surface, a button of softer material than the friction means, and means for adjusting the button over the shank to cause'the serrations to bite into the softer material of the button to present a nonslip relation between the friction means and button.
3. A tuning peg for stringed musical instruments, comprising a shank having a tapered surface adjacent one end and a bored square section at the opposite end, a button of relatively soft material having a square hole to receive said square section, a screw projecting through said button and adjustable in the bore of the square section to move the button towards the tapered surface of the shank, and an intermediate member mounted on said shank and provided with a tapered friction surface opposed to the tapered surface of the shank and having a serrated surface to engage and penetrate the softer surface of the button under tightened adjustment of the screw to present a non-slip relation between the friction means and button.
4. A tuning peg for stringed musical instruments, comprising a shank a portion of which is shaped to enter a peg hole in a peg head, a button of relatively soft material disposed on said shank, and a sleeve member interposed between the peg head and button, one end of the sleeve member engaging the peg head and the other end of the sleeve memher having a serrated surface to bite into the softer adjacent surface of the button to establish a non-slip relation of the cup member and button.
In testimony whereof I afiix my signature.
