WELLS HERBERT PORTER, OF ALBION, NEW YORK, ASSIGNOR OF ONE- HALF TO FRANK SHERWOOD, OF ALBION, NEW, YORK.

TUNING-HAMMER.

SPECIFICATION forming part of Letters Patent N 0. 77 5,383, dated November 22, 1904.

Application filed February 20, 1904. Serial No. 1%,558. (No model.)

To all whom it may concern:

Be it known that I, WELLs HERBERT POR- TER, a citizen of the United States, residing at Albion, in the county of Orleans and State of New York, have invented a new and useful Tuning-Hammer, of which the following is a specification.

This invention relates to devices for turning the posts or pins holding the strings of musical instruments.

The particular object of the present invention is to provide a novel combination of elements for effecting an accurate movement of the key various distances in order that the post operated upon may be similarly turned and the string held by said post properly tensioned without difiiculty, so as to produce the sound desired.

The preferred embodiment of the invention is illustrated in the accompanying drawings; but an inspection of the claims hereto appended will clearly indicate that various changes may be made and equivalent elements employed without departing from the spirit or scope of the invention.

In the drawings, Figure 1 is a perspective View of the improved tuning-hammer. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a sectional view on the line 3 3 of Fig. 2.

Similar reference-numerals indicate corre sponding parts in all the figures of the drawings.

In the embodiment illustrated a pin-engaging element 4 and a hammer element 5 are employed, which elements are relatively movable. The pin-engaging element comprises a head 6, carrying a spindle 7, provided with an, angular pin-receiving socket 8. The head has also attached thereto 'an offset-arm 9.

' The arm 9 in thepresent structure is detachable from the head, being provided with a nipple 10, screwed thereinto and ordinarily held against accidental disassociation and turning by a jam-nut 11. The arm 9 is provided on one side with longitudinally-disposed spaced guide-flanges 12. The hammer element 5 comprises a handle 13, carrying at one end a longitudinally-disposed stem 14, arl ranged longitudinally of the arm 9 and fitting between the flanges 1 2, the free end of the stem 14 being pivoted, as shown at 15, to the ends of the flanges which are contiguous to the head 6. It will therefore be observed that the hammer element 5 is relatively movable with respect to the pin-engaging element and that a portion of said pin-engaging element, or, in other words, the offset arm 9, is disposed in the path of movement of the stem 14 of the hammer element, which is adapted, therefore, to strike against the same between the flanges 12. 1

In order to accomplish the relative movement of the two elements 4. and 5, an actuating-lever 16 is employed, pivoted to and between a pair of ears 17, carried by the stem 14 of the handle and located adjacent to the free end of the offset arm 9. This lever 16 extends longitudinally of the handle 13 and is also provided with a handle portion 18, coacting with said handle 13. The portion of the lever through which the pivot 19 passes is offset, as shown, and is furthermore provided with a rounded head or knob 20, that is engaged in a recess or seat .21, formed in the free end of the offset arm 9.

The operation of this device may be briefly described as follows: The pin-engaging element is properly positioned upon the pin or .post to be turned by placing said pin or post in the socket 8, and if the post is to be turned some distance direct pressure can be applied to the handle 13 by the operator. If, however, the adjustment is to be very accurate and the movement slight, the handle portion 18 of the lever is moved toward the handle 13, while the operator at the same time exerts considerable pressure against said handle 13, but not suflicient to move the post. The position of the parts after this movement has been made is substantially as indicated in dotted lines in' Fig. 2. The stem 14: of the hammer element will be spaced from the offset arm 9 of the pin-engaging element. As soon as the lever is released the hammer element, acting under pressure from the operator, will swing around and strike the arm 9, giving a sudden jar or tap, which will effect a partial movement of the arm and a corresponding partial revolution of the shank 7. The force of the blow thus imparted can be regulated as desired, and great accuracy of movement on the part of the post thereby obtained, so that the device has proven very advantageous over the well-known devices of this character, not only on account of the accuracy obtained, but also because of the ease and rapidity of manipulation. If a post or stem is to be turned in an opposite direction, it will be apparent that by loosening thejam-nut 11 the offset arm, with the handle, can be reversed, so as to act in an opposite direction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a tuning-hammer, the combination with a pin-engaging element, of a hammer element freely movable for a limited distance in one direction with respect to the pinen gaging element, said pin-engaging element havinga portion disposed in the path of movement of and arranged to be struck by the hammer element duringits movementin the opposite direction, the impact of such blows effecting the movementof the pin-engaging element.

2. In a tuning-hammer, the combination with a pin-engaging element, of a hammer element attached to the pin-engaging element and having a free movement for a limited distance with respect thereto in one direction, said pin-engaging element having a portion disposed in the path of movement of and arranged to be struck by the hammer element when moving in an opposite direction, the impact of such blows effecting the movement of the pin-engaging element.

3. In a tuning-hammer, the combination with a pin-engaging element, of a hammer element pivoted to the pin-engaging element and having a free swinging movement thereupon for a limited distance in one direction, said pin-engaging element having a portion disposed in the path of movement of and arranged to be struck by the hammer element when moved in an opposite direction, the impact of such blows etfeeting the movement of the pin-engaging element.

4:. In a tuning-hammer, the combination with a pin-engaging element comprising a head and an offset arm, of a hammer element pivoted to the pin-engaging element, said hammer element having a free movement for a limited distance in one direction and arranged to strike the offset arm thereof when moved in an opposite direction, the impact of such blows effecting the movement of the pinengaging element.
