Patent d Jan. 1, 1907.
Ahplication filed Novemhei" 16,1903. sri rntfitilsoz Chicago, Illinoisy'. have invented certain new and'use'ful' Improvements in Tools for the.
Use of Piano Tuners and Makers, whereofthe following is a specification.
" 'In the adjustment of a piano-action, both beforeand atter'itleaves the factory, it is regulate the spacing.- of the hammers and a s'of to correct twisted hammer-shanks. The hammer shanks "be-l ing made of w'ood;this has commonly been" done by'means ofyheat applied by an.alcohol or Bunsen flame, the shanks being bent into frequently necessary t shape'under the influence of the heat.'. I
hav eidiscovered'that these operations can be performed without the use of'heat, and I ave invented a tool for performing them...
This tool I make. in the form of pliers, and I havfeso constructed that "a variety of other operations can'be performed with it in addition to those named.
Inthe accompanying drawings I have shown a pliercontaining my invention in what: I
now consider its best'form.
Figure 1 is a side elevation of the tool. Fig. 2 is a to elevationof' same. Fig. 3 is a top view of t e lower nose of Fig. 1. Fig. 4 is an end 'view of magma view of the,to nose of Fig. 1. section at 6 6 0 Fig. 1. 7.7 of Figi'i'." Fig.8 is'a view from below of the end of ,thej lower. handle of Fig. 1. Fig. 9 is an end view of th'eg'same. Fig. 10 is a side elevation of the-pli'e'r witha modified nose.
Fig. 11 is" a .to elevation of thesame. Fig.-
12 shows .theiaceof tl ie lower jaw of same. Fig. 13*showsthefaceof the upper jaw of.
same. Fig. 14 is an end view oi the ,nose
of same. In thesevarious figures, 1 and 2 are registering semigrooves,and 3" and 4 are registering semigrooves, in the nose of thepliers. These registering grooves form two holes of approximately circular crosssection, and-of about the size.of or a trifle larger than a hammer-shank. The semigrooves 1 and 2 are both curved upward, as seen in' Fig. 7, ,so. that the bottom .of 1 presents a concave appearance, tom of 2 presents a convex appearance. The convexity of 2 is greater than the concavity of 1, so that the hole formed by the grooves is smaller in the middle than at the ends. In
it is applied to the s Fig. '5 is an under 1 Fig. 6is a Fig. 7 is asection at and the bot-v the fiberoi the wood is v.ery-slightly upset,
The twosemigrooves 3 and 4.ar e both convex across the nose of the pliers, as seen in Fig. 6, so that'th'e hammer-shank is upset to greater degree than in the case of grooves '1 and 2. v In case of a twisted hammer-shank,whichcannotbe bothbent and twisted to pro er osition twisted and set Withthe greater ressure of wood and cause the shank to maintain its 0- sition. function'in s acing the back-checks, as the grooves stra dle the bridle wire and permits the shankof theLback-check to'be seized by 'thenose of the pliers. The nose of the pliers may also be used fora key-plier for ing and engaging the key-mortises; For this and so sets the shank in the position assumed,
and set withgrooves 1 and 2, t e s ank is grooves 3 and 4, which upset the her of the spreada semigroove 2.01; the the I shank must be bent and pressure is exerted. This bends the shank, and at the same time These grooves also have .anot er purpose one member of thefnose js reduced in member 6 is of a flat spheroidal shape-that size to enter the mortise and flithe' opposing is, convex in all"directions, 'sdas'to give a q as firm-grasp. of the mateiial of the key whatever the obliquity of the mortise may be.
