SUPPORT FOR BEE-LOWS.

Specification of Letters Pit-tent.

Application filed December 6, 1907. Serial No. 405,310.

To all whom it may concern:

Be it known that 1, Jose sA-MPERE, subject of the King of Spain, resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Supports for Bellows, of which the following is a specification.

My invention relates to supports for bellows which are used in automatic pianos and has for its object to support the said bellows in such a manner as to make them easily removable from'the instrument. My improved support also insures the proper replacing of the bellows in position in the instrument and I furtherprovide a means for locking the bellows securely in operative position.

.Other objects of my invention will appear from the annexed description and the fea tures of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings in which Figure 1 is a front elevation of my improved device; Fig. 2 is an end view thereof; Fig. 3 is a front view of another form of my device, an]? Fig. tis an end view thereof.

A and are the bellows which are mounted on the wind chest C and are connected with the pedals and operated in the usual way.

D is the connection from the wind chest C to the action. The wind chest is provided with supporting members E which are secured to said wind chest by means of screws E. These supporting members E are provided at their lower extremities with notches or recesses F which are adapted to take over or engage a rod G. This rod Gis secured in supports H, which in turn are fastened to the base board H of the instrument. These supports H are so located that when the members E are in position on the rod G, the said! members E are located exactly between the two supports H and engage the same. In other words the distance between the outer surfaces of .the members E is slightly less than the distance between the inner surfaces of the support H. The correct replacing of the bellows is thus insured as the supports H act as positioning memhere. provide screw-threaded lugs I which may which are adapted to cooperatewi-th similar lugs J on a stationary part of the instrument. Thumb screws K are screwed into the lugs I and are arranged to screw into the lugs J andthus maintain the bellows in operative position. \Vhen it is desired to remove the bellows the connection between the pi e D and the action, which connection is pre erably a flexible one, is first removed, and the thumb screws K are unscrewed from the lugs J which leaves said bellows, with the wind chest, free to Be lifted out. of the instrument, the rod Gr serving as a bearing on which to swing the members E.

To replace the bellows and parts in operative position, one supporting member E is engaged with any part of the rod G and then moved lengthwise of said rod until it abuts against one of the supports H. This positions the bellows and parts and all that is necessary is to engage the other support H with the rod G and swing the parts back into operative position. The end portions of said rod G thus form bearings for the supporting members E while the intermediate portion of said rod serves as a guide for guiding the said supporting members to the bearing portions of said rod.

In Figs. 3 and 4 instead of the members E, I provide rods or supporting members L which are secured to the bellows and are provided with spherical ends L. These ends L are adapted to enter recesses M in a base member M which is secured to the base board H of the piano. This base member M is further provided with a projection M extending lengthwise thereof at the rear edge of said base member. The rods L and the recesses M are equally spaced so that when the'bellows are in position the spherical end of each rod L will be in position in the corresponding recess M. may be secured in operative position and ma be removed in the same way as described with regard to the structure shown in Figs. 1 and 2. After the bellows have been removed and it is desired to replace them in position, the spherical ends of the The bellows M and then moved lengthwise of the base ;member M until the said spherical ends To secure the bellows in position I 5 form part of the supporting members E and 9 drop into the recesses M. The projection M prevents the rods I from being pushed across the base member and further serves in position. In this form also as in the form of as a guide for the replacing of the bellows with the lining N and its other end with the movable member of the bellows. In other words the spring 0 is located between the movable member of the bellows and the upwardly extending portion N This spring tends to normally maintain the bellows in a collapsed condition and returns the bellows to this condition each time pressure is removed from the usual pedals. By having the spring secured in this manner, it is carried by the bellows and comes with said bellows when they are removed from the instrument together with the member N. The danger of misplacing or losing the spring is thus avoided. In replacing the bellows in position it is also unnecessary to exercise any care to see that the spring is l eaee'ro properly replaced as is necessary under existing conditions.

I claim:

1. The combination of a wind-chest, bellows secured to said wind-chest in communication therewith, supporting members for said wind-chest and bellows, and a continuous member arranged to be engaged by said supporting members to form a bearing therefor and to also serve as a guide for uiding said supporting members to their final position thereon.

2. The combination of a wind-chest, bellows secured to said wind chest in communi cation therewith, supporting members for said wind-chest and bellows, a continuous member arranged to be engaged by said supporting members to form a bearing therefor and to also serve as a guide for guiding said supporting members to their final position,

and means on said member for positioning the supporting members thereon.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

JOSE SAMPERE. Witnesses:
