PIANOFORTE ACTION.
No. 585,740. Patented'July 6, 1897 UNITED STATES PATENT OFFICE.
BENJAMIN F. CARR, OF CHICAGO, ILLINOIS.
PlANOFORTE-ACTION.
SPECIFICATION forming part of Letters Patent N 0. 585,740, dated July 6, 1897.
Application filed December 31, 1895. Serial No. 578,947. (No model.)
To all whmn it may concern:
Be it known that I, BENJAMIN FRANKLIN CARR, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvementin Pianoforte-Actions, of which the following is a full, clear, and exact speciiication, reference being had to the accompanying drawings.
My invention relates to piano-actions; and it consists in a construction which will permit of the use of a metal main rail and connections, as will hereinafter be fully described in the drawings.
Figure l is a side View of a part of a pianoaction embodying my invention. Fig. 2 is a rear view of the same; Fig. 3, an exaggerated detail section showing the connection between the damper-levers and the main rail and the hammer pivot-block. Figs. 4: and 5 are modifications. Fig. 6 illustrates the connections between the extension-rail and guide.
A is one of the keys; B, a key-rocker; C, an extension which connects the rocker with the wippen D.
E is the extension-rail, which extends from one end of the piano to the other, and F is a guide, one of which connects each extension C with the rail E. The rail E is of metal and is formed with lugs on its upper edge, as shown in Fig. 6, each lug to receive the furcated'end of an extension-guide F, the other end of which is pivoted to one of the extensions C. A pivotal connection is made be tween the rail and guide by means of a bolt a, which connects the ends of the furcations of each guide, and after the furcation is placed over the lug on the rail a cap Z), having a groove in the face of the lug c, that projects from its upper edge, is screwed onto the rail, so that its groove embraces or clamps the pin up against a lug of the rail, and as the lug of this cap projects between the furcations of the extension-guide a slight twist of the cap will tend to deflect the guide laterally to adjust th e extension beneath the wippen or upon the key-rocker.
The wippen and hammer are connected in the usual way by ajack G.
H is the main rail of the instrument. This I make of metal, either in two parts, as shown in Figs. 1 and 2, or in one piece, as in Fig. 4.
The wippen is suspended from its lower end by a clamp cl. The upper edge of the main rail is flanged, as at h 2', and to these flanges are pivotally clamped the hammer-block J and damper-lever K by means of a single plate f, having grooves on its under side to embrace the pivots g and 6, respectively, or by two plates in and 19, each of which clamps a pivot, as shown in Fig. 4.
The pivot 9 passes through a concavity in the damper-lever and serves as an anchor for the damper-spring, which is twisted about it.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, i.s
The combination in a piano-action of clamps for the pivots each comprising a fixed and a movable part having the groove in the movable parts as and for the purpose set forth.
BENJ. F. CARR.
