FRED E. H. GOODENOW, OF SPRINGFIELD, MISSOURI.
PIANO TUNING-PIN.
SPECIFICATION forming partof Letters Patent No. 375,150, dated December 20, 1887.
Application filed May 11, 1887. Serial No.237,850. (No model.)
To all whom it may concern.-
Be it known that I, FRED E. H. GooDENow, of Springfield, in the county of Greene and State of Missouri, have invented a new and Improved Tuning-Pin for Musical Instruments, of which the following is a full, clear, and exact description.
Theobject of my invention is to provide a new and improved tuning-pin for pianos and other musical instruments, which pin is securely held in place and is not materially influenced by a changeof temperature.
The invention consists of certain parts and details and combinations of the same, as will befullydescribed hereinafter,and then pointed out in theclaims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional elevation of my improvement. Fig. 2 is a side elevation of the bushing in which the tuning-pin turns. Fig. 3 is a plan view of the same. Fig. 4 is a side elevation of the clamping-collar. Fig. 5 is a plan view of the same. Fig. 6 is a side elevation of the nut for screwing the clamping-collar against the bushing, and Fig. 7 is a plan view of the same.
My improved tuningpin A is provided on its upper part with the shank B, having the usual aperture, B, in which is fastened one end of a string, S, adapted to be wound on said shank B. The upper end, B", of the latter is square in cross-section, and is adapted to fit into the similarly-shaped tuning-hammer, by which the tuning-pin A is turned to adjust the string S.
On the shank B is formed the collar 0, and from the under side of the collar 0 projects the round part D of the pin A, which partD continues into the square part E, and the latterterminates in the threaded portion F. The round part D of the pin A fits into a round aperture in the square bushing G,in which the pin A turns, said bushing G being preferably of brassand held vertically in a square aperture formed in the cross-beam H, of iron or other suitablematerial, and secured to the piano or other musical instrument on which 1 my improvement is used. On the top and bottom of the bushing G are held the washers I and I, respectively, which are preferably of the same material as the bushing G and fitted loosely on the round part D of the pin A.
A clamping-collar, J, is provided with acentral square aperture,which fits upon the square part E of the pin A and turns with the latter.
The square a erture of the clamping-collar J- extends only half the height of said collar,and is continued into a round aperture, J, of sufficient size to fit, when necessary,over the round portionD of the to ning-pin A. On the threaded portion F of the tuning-pin A screws the nut K, which is provided near-its upper end with an enlarged aperture, K, adapted to slide over the square portion E of the tuning-pin A whenever necessary. The washers I and 1 extend slightly beyond the edges of the fixed bushing G, so as to rest with their clampingfaces against the top and bottom, respectively, of the cross-beam H, as shown in Fig. 1.
My improved tuning-pin A is put in position in the following manner: The fixed bushing G is placed in the respective aperture in the cross-beam H, and then the pin A is inserted into the central aperture of the bushing G, with the washer I held between the bushing and the fixed collar G on the round part D of the pin A, so that the under side of the fixed collar O rests on the top of said washer I, the bottom of which rests partly on the top of the bushing G and partly on the top of the crossbeam H. The washer I is then slipped on the lower end of the round part of the pin Auntil it rests against the'lower end of the bushing G and against the bottom of the cross-beam H, as shown in Fig. l. The clamping-collar J is then slipped over the threaded portion F upon the square part E, and then the nut K is screwed on the threaded portion F until the clamping-collar J is pressed by said nut K against the under side'of, the washer I. It will be seen that the pin A is now held firmly in place in the bushing G and on the washers I and I, and is prevented from moving in the direction of the pull exerted against the pin A by the string S.
Then the piano-tuner desires to turn the tuning-pin A, he fits his tuning-hammer on the square part B of the shank B and turns the hammer in the usual manner and with such force as to overcome the pressure with which the pin A is clamped by the nut J against the washers I and I, so that the tuning-pin A turns in the bushing Gto the amount required for tuning the string S.
It will further be seen that as the tuning-pin A and its connecting parts are preferably made of metal the pin A is not liable to be affected by change of temperature,as the ordinary pins are, on account of being screwed into wood, which is liable to be shrunken by change of temperature. The bushing G and the washers I and I, on account of being brass, prevent the transmission of metallic sounds from the crossbeam H to the tuning-pin A and itsstring S.
The clamping-collar J is provided with the round aperture J, so as to permit of using the same pin, A, in case the bushing G is of less height, whereby said round aperture J fits over the round portion D of the pin A. Ina similar manner the nutK is provided with the round aperture K, which is sufficiently large to fit over the square part E of the tuningpin A.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a tuning-pin having a fixed collar, of a fixed bushing in which said pin turns, washers held on said pin and against the top and bottom of said bushing, a clamping-collar held on said pin and turning with the same, and a nut for pressing said clamping-collar against thelower washer, substantially as shown and described.
2. The combination, with a tuning-pin having a fixed collar, of a fixed bushing in which said pin turns, washers held on said pin and against the top and bottom of said bushing, a clamping-collar having a square aperture and held on the square part of the said tuning-pin, and a nut screwing on the threaded lower end of said tuning-pin and against said clampingcollar, so as to press the latter against the bottom of said lower washer, substantial] yasshown and described.
3. The cross-beam H, provided with a series of square apertures, a square bushing, G, held in each of said square apertures, and washers I and I,held, respectively,on the top and bottom of said bushing and said cross-beam, in combination with the tuning-pin A, having a fixed collar, 0, resting on the upper washer, the clamping-collar J, having a square aperture and fitted on the square part Eof said pin A,the
nut K, screwing on the threaded portion F of the pin A and adapted to press said clampingcollar J against the lower washer, I, substantially as shown and described.
