GEORGE WV. NEILL, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN UPRlGHT-PIANO ACTIONS.
Specification forming part of Letters Patent No. 197,526, dated November 27, 1877; application filed October 10, 1877.
To all whom it may concern:
Be it known that I, GEORGE WV. NEILL, of Boston, of the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Actions for Upright Piano-Fortes; and do hereby declare the same to be described in the following specification and represented in the accompanying drawing, which exhibits a side elevation of my improved action.
My improvementconsists in the combination of a stationary bar and a pivoted supportingarm with the back-catehand the fly-supporting arm or bed, all being arranged essentially as set forth.
The advantages of the improvement over most, if not all, ordinary modes heretofore in practice for supporting the back-catch are, that it enables it to better sustain the hammer,
1 and the latter to repeat with more certainty and useful effect.
In the drawings, A denotes the key; 13, the hammer; O, the jack or fly, and D the bed or supporting-arm of such fly. This bed is pivoted to a stationary rest or bar, a, the fly being hinged to the bed at its front. The said bed rests on the top of a push-rod, b, which, at
its lower end, is pivoted to a rocker or adjust able lever, c, fixed to the key.
From the hinge-block of the hammer an arm, (1, projects backward, and is provided with a head, 0, for the back-catch f to bear against. The wire g of the back-catch extends upward from a sustaining-arm, 71 which, hinged to a stationary bar, 1', rests on the bed D. The back-stop E of the fly is arranged over the bar '1 as shown. A strap, F, extends down from the hinge-block of the hammer to, and is fixed to, a wire, G, projecting from the bed I).
The key being struck, the fly-bed will force upward the supporting-arm of the back-catch, which arm will fallwith the said bed while the key may be in the act of rising.
I cl.aim
In an upright-piano action, the combination of the straining-bar i and the pivoted supporting-arm h with the back-catch and the flysupporting arm or bed, all being arranged substantially as set forth.
GEO. WV. NEILL.
