PIANO-ACTION FLANG-E.

Specification of Letters Patent.

Patented (Det. 19, 1%515.

Application led August 3, 1914. Serial No. 854,762.

To all whom t may concern.'

Be it known that I, VILLIAM J. LUTH- MnRs, a citizen of the United States, residing at` Olney, in the county of Richland and State of Illinois, have invented certain new and useful Improvements in PianoQAction Flanges; and I do declare the following to bel a full, clear, and exaet`description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' My invention relates to piano actions, but more especially to flanges used in conjunction with the latter to pivotally support the hammer and damper in their proper position.

One object of this invention is to provide a device of this character having means for partially enveloping the `transverse rails of a piano which will prevent horizontal movement onethe part of said flange.

A further object is toprovide means for the removal of the hammer without neces sitating the withdrawal of the flange. Y

A still further object is to provide a unique means for retaining the hammer and damper springs in proper position which will at the same time permit of their ready removal.

A still further object is to simplify the construction of the parts whereby they may be made more -accessible when repairing. is necessary.

With these and other objects in view my invention consists of certain details of construction and combination and arrangement of parts which will be more particularly pointed outand claimed.

In the accompanying drawing 'in which corresponding parts are designated by similar reference numerals Figure 1 is a vertical section taken across the rails 0f the piano actionand illustrating the damper and hammer butt connected by my improved flange. Fig. 2 is an enlarged transverse vertical section of the hammer butt, damper and rail, illustrating my improved flange applied to the latter, .and positioned to pivotally retain said hammer and damper. Fig. 3 is a similar view showing the flange members separated and in position to receive the pintle of the hammer butt. Fig. 4 is a plan View partly in section. Fig. 5 is a detailed vertical section taken on the line 5-5 of Fig. 2.

In its present exemplification my improved flange comprises a substantially U- shaped lower plate 1, formed of any suitable resilient metal, and adapted to be seated upon and partially embrace the longitudi nally extendingtongue 2 on the main rail 2 whereby any horizontal movement on the part of said body 1 is prevented as clearly shown in Figs. 3 and 4. Extending laterally from the body 1 are the two arms 3 and 4 which are ireduced at their outer portion as at Overlying the U-shaped plate 1, in fact the latter may be said to telescope therein, is a similarjshap'ed upper plate 6 formed of the same material, and carrying laterallyprojecting arms 7 and 8 which overlie the arms 3 and 4 and have their outer portion so reduced.v as to make the configuration thereof identical to that of the underlying arms 3 and 4. The meeting edges of two of these arms 3 and 7 are united, and immediately adjacent their united edges they are formed with the transverse opening 9, which receives the pivotal pin 10 in the damper 11, whereby the latter may be pivotally supported in its proper position as will be readily understood.

As it is frequently desirable to detach the hammer 12 for repairing or other purposes without disturbing the damper 11, the inner `faces of the arms 4.and 8 which by reason of the resiliency of the plates are normally separated, have formed in their adjacent faces contiguous to the extremities thereof transversely extending channels 13. These channels coact when the arms 4 and 8 are brought together, so as to completely house and pivotally retain the pin 13 carried by the hammer butt 14.

To permanently maintain the flange in its adjusted position upon the rail 2, the telescoping U-shaped plates 1 and 6 are formed with a centrally arranged registering opening 15, through which and into said rail 2 there passes a screw 16. With the plates arranged in this manner and the screw 16 passing therethrough as aforesaid, adjusting the latter will cause said plates as well as the arms carried thereby to be pressed into contact, so that if the pin 13 of hammer butt 14 is disposed between the arms 4 and 8, in alinement with the channels therein, when said arms have been fully brought together the pin 13 will be entirely vinclosed by the Walls of channels 12, and thereby suitably pivot the hammer butt 14. In view of the above it will be apparent that adjusting the screw 16 Will cause the arms 8 and l1 to be brought in to or out of engagement as the case might be thus permitting the hammer to be removed or brought into proper position Whenever desired.

ln order that the damper and hammer' springs may be easily removed and replaced when broken as Well as to avoid the necessityl of a bridle ribbon and Wire as Well as an additional hammer spring supporting rail, l' provide the sides of the U-shaped plates 1 and 6 with registering openings 17 and l7i. The former 17 beipgin one side thereof, and the other 17 being formed in 'the opposite side, and in diagonal relation to the opening 17 as clearly shown in Fig. li.

into these openings are fitted/the lower extremities of the springs 18, the upper eX- tremities thereof contacting with the damper and hammer in the usual manner. rl`he' simplicity of this construction alloWsa spring to be easily replaced When desirable, and at the same time prevents the separation of the upper and lower plates should the screw 16 be accidentally loosened through vibration or other causes.

lt vvill thus be apparent that l have effeeted a flange which is simple, inexpensive to construct, elhcient in operation and one which will greatly reduce the cost of repairing.

From the foregoing description, taken in connection with the accompanying drawings, the constructionk and operation of the invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resortedto/ Without departing from' the principle or sacrificing any of the advantages of the claimed invention.
