UNITED STATES PATENT OFFICE.
CHARLESN'. SCHNEIDER, 0F NEW YORK, N. Y.
Application. filed November 23, 1923.l
To all whom it 77mg/ Concern:
Be it known that I, CHAR-Lies N. SCHNEL- Dnn, a. citizen of` the UnitedStates, and a resident ofthe city of New York, borough of Manhattan-7 in the county and State of New York, have invented a new and iinproved Bridle-Strap-Attaching Tip, of
which the following is a full, clear, and enact description.
This invention relates to improv ementsA in pianoactions and has'partionlar refer-l obviates. the necessity of removing the back stop shank when the original bridle-Strap is replaced byL anew one.
Another object. in view is to provide an attaching tip which is engageable in the usual opening formed in the back stop, which tip operates to securely anchor the bridle-strap and which tip further functions pas. a.. buffer element incase of' the loss of the. usual felt buffer which is carried by the. backy stop..
As` a still further object the inventionI contemplates an improved form of. attach` ing tip which is comparatively simple in its construction and mode of attachment, which is inexpensive to manufacture and which is thoroughly reliable and highly efficient in its purpose.
`With. the above recited and other objects in view7 the invention resides in the novel construction set forth in the following speciiication, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are eX- pressed.
In the drawings Figure 1 is an elevation of a portion of the piano action illustrating ithe improved Serial No. 676,603.
form of bridle-strap attaching tip in applied position.
Fig. 2 is a face view of the back stop with the improved bridle-strap att-aching means iii-position.
Fig. 3 is a fragmentary enlarged sectional view of the tip in position in the back stop opening.
Fig. i` is a detail perspective view ofv theV yieldable sleeve of the attaching tip removed'.
Fig. is a perspective view of a repair bridle-strap with the attaching tip conneeted thereto and illustratingthe shape of the tip prior to its association with the back stop.
Referring to the drawings by characters of'reference, 10 designates the hammer butt of a piano action, 11 the back stop and 12 the back stop shank, the said back stop being provided with the usual opening 13. therethrough for theV passage of the bridlestrap 14. It is the usual'practice to insert the extremity of the bridle-strap 14 in the opening 15 of the hammer butt whichreceives the back stop shank 12. However, when the bridle-strap wears and breaks it necessitates the removal of the back stop shank in ordel` to insert the extremity of' a new bridle-strapv therein.` This necessitates the removal of a number of parts of the action which not only consumes time and necessitates additional labor, but puts the piano out of action until the glue which normally retains the back stop shank in the opening 15, has dried. The attaching tip constituting the present invention consists of aheaded element` 1G having a shank 1T which is preferably threaded and a yieldable sleeve 18 which is preferably of rubber adapted to snugly embrace and cover the shank 17. The terminal 19 of the bridlestrap 141 is inserted between the shank and the sleeve to constitute a repair bridle-strap for replacing a worn or broken one. In assembled form, as illustrated in Fig. 5, 4the` shank 17 is only partially inserted into the yieldable sleeve 18 with the terminal 19 of the bridle-strap interposed between the shank and sleeve. The shank 17 is of a larger diameter than the normal internal bore of the sleeve, while the external diameter of the sleeve is slightly less than the diameter of the opening 13 in the back stop. It is thus obvious that the shank in partially inserted position in the sleeve facilitates the initial insertion of the unexpanded end of the sleeve into the opening 13 of the back stop v11. When the sleeve is inserted, the shank 17 is forced further into the bore of the sleeve and the sleeve is forced through the opening 13 by an oscillatory movement preferably by inserting a screw driver in the kerf 21 of the headed element 16. After the sleeve is forced through the opening till the outer end of the same protrudes into the flared inner end of the opening 18, the Vtip will assume the; position illustrated in Fig. 3. The length of the sleeve and shank is such that the said sleeve will protrude beyond the inner end of the opening 13 to form a bulge 22 at this point, thereby securely anchoring the tip in place against accidental or casual Withdrawal. The bulged portion 22 further serves as a yieldable bui'ting element in vcase the usual buffing element of felt has been lost. It is obvious that the attachment of the bridle-strap at this point in no way interferes with theV usual functioning of the same and it will be further apparent that the time required for attaching the bridlestrap is reduced to an absolute minimum.
I claim: Y
1. A tip for attaching av bridle-strap to the back stop of a piano action comprising a pair of telescopically associated elements between which the terminal of the bridlestrap is clamped, said elements being insertable in the opening in the back stop.
2. A tip for attaching a bridle-strap to the back stop of a piano action comprising a pair of telescopically associated elements between which the terminal of the bridlestrap is clamped7 said elements being insertable inV the opening in the back stop, the outermost element being of a yieldable material and of slightly greater diameter than the diameter vof the opening in the back sto 3l.) VAn attaching tip for the bridle-strap of a piano action, comprising a member including a shank having a head at one end.
a yieldable sleeve telescopically arranged thereover with the terminal of the bridlestrap received therebetween, said tip in assembled relation being forcibly inserted in the opening in the back stop. ll. An attaching tip for the bridle-strap of a piano action, comprising a member including a shank having a head at one end. a yieldable sleeve. telescopically arranged thereover with the terminal of the bridlestrap received therebetween, said tip in assembled relation being forcibly inserted in the opening in the back stop, the said sleeve at'the end remote from the head adapted to protrude through the back stopV opening whereby to expandand forman anchoring bulge.
5. The combination with the back stop of a piano action provided Ywith an opening ltherethrough for the passage of the usual bridle-strap, of means for anchoring Y the terminal of the bridle-strap in the opening in the back stop comprising a member having a threaded shank provided with a head at one terminal, a yieldable sleeve embracing said shank, the outer Vdiameter of which is greater than the diameter of the opening in the back stop shank, the terminal of the bridle-strap being clamped between the sleeve and shank, and sleeve, shank and bridle-strap terminal being forcibly inserted in the back stopopening.
6. A tip for attaching a bridle-strap to the back stop of a piano action, comprising a pair of telescopically associated elements between which the terminals of the bridlestrap is clamped, said elements being insertable in the opening in the back stop, the outermost element being of a yieldable contractible Ymaterial which is adapted to be expanded by the innermost element to a diameter slightly greater than the diameter of the opening in the backstop atthe point of protrusion of the free end ofthe cuter element beyond said opening in the back stop.
