J. HBRRBURGBR. PIANO ACTION.
Patented Mar. 29, 1892.
ATTORNEYS.
UNITED STATES PATENT OFFICE.
JOSEPH HERRBURGER, OF PARIS, FRANCE.
PIANO-ACTION..
SPECIFICATION forming part of Letters Patent No. 471,717, dated March 29, 1892.
Application led June 5, 1891. Serial No, 395,181. (No model.)
To all whom t may concern:
Be it known that I, JOSEPH HERRBURGEE, of Paris, France, have invented an Improved Piano-Action, ot which the following is a specification.
This invention relates to a repeating-action for upright pianos of the kind in which the 'fixed back-check is dispensed with and supplanted by a back-check secured to and moving with the hammer-butt.
The invention consists in the various features of improvement more fully pointed out in the claim.
1n the accompanying drawings, Figure l is an elevation ot" my improved action with the key raised; Fig. 2, a similar elevation with `the key depressed, and Fig. 3 a detail of the hook e.
'The letter a represents the key of an upright-piano-forte action. b is the lever, c the jack, and dthe hammer-'butt'. The butt CZ is provided with a padded notch d', that is engaged by a rearwardly-projeeting nose c of the jack. Opposite said nose the jack c is provided with an upwardly and forwardly eX- tending head c2, having a straight padded front edge c3. The upper edge cLl ot` head c2 is slanting, extending downward from the edge c3 to the nose c', so that thus the edge c3 projects a considerable distance farther up than the nose c', as shown.
To the hammer-butt d there is secured the shank of a hook e, the head e of which is straight from top to bottom and is in line with the edge c3 when the key is depressed, Fig. 2. This head e of the hook is flattened laterally, as shown, so as to afford a firm and wide bearing for the jack. Then the key is depressed, the nose c will throw the hammer against the string, and will then partly slip out of the notch d to permit the hammer to fall away from the string. continued until the edge c3 comes into contact with the head e of the hook e, when the jack will serve as a back-check. A slight release of the key a will now cause the jack to come lclear of the hook, so that the nose c is reintroduced into the notch d', ready for the next depression of the key. In this way a very sensitive repeatingaction is produced.
'What 1 claim is- The combination of a jack having a rearwardly-projecting nose c and a forwardlyproject-ing head c2, that extends above the nose, with a mortised hammer-butt, and a hook secured thereto, substantially as specified.
JOSEPH HERRBURGER.
