UNITED STATES JOHN LINDSTROM. F HENDERSON, KENTUCKY.
Application filed April 5,
To @ZZ #uf/funn it' may concern:
Be it lrnown that I, .loirN LiNns'rnoM, a citizen of 'the United States, residing at Henderson, in the county of Henderson and State of Kentucky, have invented certain new and useful Improvements in Violin Pegs, of which the following is a specification, reference 1neing had to the accompanying drawings.
This invention relates to pegs more partieularly de hned for violins but adaptable to ed instruments, such as violinother str.A celles, guitars, banjos, and the like, and one et the objects of the invention is to provide a peg of this character which will positively hold against the rotative strain applied to it by the tension of the string.
Another object in this connection is to provide means whereby the frictional resistance to the reverse rotation of the peg may be increased or decreased as desired. Still another object is to provide means whereby the string which, as usual, paes through a hole in the peg, may be positively engaged so that short strings, incapable of being wrapped around the peg, may be utilized and positively engaged with the peg.
Other objects have to do with the details of construction as will appear more fullw7 hereinafter.
lMy invention is illustrated in the aecompanying drawings, wherein Figure 1 is a face view of a violin head showing my tightening peg in section;
Figure 2 is a section on the line 2-2 of Fig. 1;
Figure 3 is a like view to Figure 1, but showing a modification of the tightening Peil? Figure 4 is a fragmentary perspective view of the construction shown in Figure 3;
liigurc is a section on the line 5 5 of Figure 1 Referring to Figure l. l() designates the head of the violin of the usual character and slotted, as at 1.1. The body of the violin is not shown, as it forms no part of this invention. The peg in Figure 1 consists of a metallic pin 12 which at one end has a. head 13 whereby the pin may be rotated. The pin is hollow, as at 15, and has a diainetrically extending opening 14 for the violin string. Entering one end of the peg 12 opposite the head 13 is ascrew 16 having a head 17 nicked for the application of 1922. serial No. 549,713.
a screw-driver or wrench. At the head end of the pin or peg 12 and between the violin head 1() and the head 13 are disposed a pair of washers 18 and 19, the washer 18 being .slightly concave-convex or dished and bearing against washer 19, which in turn bears against the edge face of head 10. The sleeve 2O is disposed over pin 12 and forms a bushA ing therefor and holds it in concentric relation to the hole through which it passes.
Between the opposite edge face of the violin head 1() and the screw head 17 is disposed a washer 21 bearing Hat against the edge face of the head 10, and bearing on this washer is a coiled volute spring 22. A small washer 21il bears against the small end of the spring 22 and the head 17 bears against this washer 21, Extending longitudinally through the head 13 and through this end of the hollow peg 12 is a screw 23 having a head 23L nieked for engagement by a. screw-driver, the extremity of this screw 23 being reduced' and intersecting the opening 14 so as to bind the string within this opening and act as a set screw for this string. This permits a short string to be used which could not be wrapped around the pin.
In the use of this device, the screw 16 is initially tightened up as tight as possible and then is turned back one-half a revolution in order to give the spring 22 a certain amount of play. Of course, where a short length string is to be used, itl is passed through the opening 14, the screw 23 being turned outward a few turns, Then the screw 23 is tightened up and the string will be held tightly. The washer 18 is annular in form for the passage of the peg and loosely surrounds the same and has a notch 18a, while the peg has a lug which extends into this notch so that this washer 18 is held for rotation with the peg, as shown in Figure Si. 'lhe washer 19 hears against thc edge face of the head and does not rot-ate with the peg.
lith this construction, the spring 22 will cause such friction between the washers 18 and 19, between the washer 19 and the side edge of the head 10, and between the washer 21 and the side edge of the head 10 that the peg will be held in any adjusted position, while at the same time it is relatively easy to rotate the peg. This friction resisting any reverse movement of the peg may be in- Cil creased by setting up the screw i6 and, of course, it may be relieved by releasing the screw 1G.
In Figures 3 and 4, I show a slightly modiiied forni of the invention which, however, embodies the same principle as the device shown in Figure l. ln this figure, the numeral l designates the head oi the violin, as before, and l1 the longitudinal slot in the head. intersecting this slot is the hollow `or tubular pin 25 formed with the opening 2G for the passage of the string. One end of the peg is formed with a worm gear wheel 27 which constitutes a head whereby the peg may be turned and the peg is interiorly screw-threaded at this end for the passage oi' a screw 28 having a head 29. This screw 28 intersects the string passage 26 so that when this screw 28 is turned home it will bind the string in the hole 26. Disposed against the edge tace of the head is a plate 30'which is approximately square in form and has a ringer 31, this plate having outwardly projecting lugs forming bear-ings 'for the support of the usual threaded key 32 whereby the peg may be rotated. The opposite end of the peg is interorly screw-threaded for the reception of a screw 33, the head o'l' this screw vbearing against a washer 34, which in turn bears against a volute spring 35, in turn bearing against a washer 37. ln other words7 the construction at this end of the peg is precisely similar to that illustrated in Figure l. The i'ngervor indicator 32, should the performer neglect to tighten the screw properly, will strike the neighboring pegv 38 and plate 30 cannot, therefore, turn around. The plate permits this ldevice to be applied yto a violin head without the necessity of passing screws through the plate 30 into the violin head, inasmuch as the finger 3l. bearing against the peg 38 will prevent any rotation oi: the plate 30. lilith this construction, the E string can be tightened l/lOO part of an inch or even less rlhe device shown in Figure 3 is best adapted for children, as by this means very little strength is required to turn the peg.
l. In a musical instrument, a tension head and a string peg therefor having a passage for a string, the string peg being hollow and intericrly screw-threaded, a head for the peg whereby the peg 'may be rotated having an opening aligning with the screw-threaded bore off the peg, and a screw extending through and engaging the screw-threads of the peg and intersecting said passage.
n n/sense i2. ,ln a musical instrument, a tension head and a string peg therefor having a passage 'for a string, the peg having a screw-threaded bore intersecting said passage and having a head at one end, whereby the peg may be rotated, and a screw extending longitudinally through the headed end oi' the pin and engaging said bore and intersecting said passage.
3. A tension head for musica-l instruments having a longitudinally extending slot, a metal peg passing through the head and intersecting' the slot, one end of the peg having a head, the opposite end being interiorly screw-threaded, a washer concentric to the peg and bearing against one face of the instrument head7 a concavo-convex washer loosely mounted on the peg to rotate therewith and concentric thereto andbearing at its edges against the iirst named washer, a screw engaging the interior screw-threads of the opposite end of the peg, a washer bearing against the side face of the instrument head adjacent said screw, and a coiled spring disposed between the screw head and said washer.
Il. A tensioning head for musical instruments having a longitudinally extending slot, a metallic pin passing transversely through the hea-d and intersecting the slot7 the pin having a diametrically extending hole disposed within the slot, one end oi the pin having a head and the pin being interiorly screw-threaded, a screw engaging the interior screw-threads and having such a length that the extremity of the screw will intersect the string opening in the peg.
5. A tensioning head for musical instruments having a longitudinally extending slot, a peg passing transversely through the head and intersecting said slot, the peg having an opening for the passage oi a string and having at one end a head, the opposite end of the peg being interiorly screwthreaded, a conczwo-conveny washer mounted upon the peg at the headed end thereof 'for rotation with the peg, a second washer surrounding the peg and against which the rst named washer bears, a bushing surrounding the peg, a screw engaging the interior screw-threads at the opposite end of the peg and having a head, a pair o'f washers mounted upon the screw and one engaging the side `l'ace oi the instrument board. and volute spring disposed between the washers.
