ADJUSTABLE EXTENSION FOR PlANO-PEDALS.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed February 3,1906. Serial No: 299.255.

T0 at whom it may concern:

Be it known that I, JOHN R. DREW, a citi zen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Adjustable Extensions for Piano-Pedals, and I hereby declare the following to be a full, 'clear, and exact descrip tion of the same.

My invention relates to that class of attachments to piano-pedals by which an adjustable extension is provided to suit particular cases, especially for children, who having to sit high enough to enable them to reach the keyboard are not able to reach the pedals with their feet.

The object of my invention is to provide a simple and effective adjustable extension for piano-pedals adapted by its construction to be readily and firmly fitted to any pedal and to be easily carried about, the latter advantage making it very serviceable to music teachers.

My invention consists in the novel construction of the adjustable extension, which I shall hereinafter fully describe by reference to the accompanying drawings, in which Figure 1 is a side elevation of my adjustable extension. Fig. 2 is a front view of the same. Fig. 3 is a cross-section on the line a: a: of Fig. 2 looking upwardly. Fig. 4 is a plan view of the foot-rest. Fig. 5 is a detail sectional view showing the connection of the jaws with the stock and a portion of the stem.

Referring to Figs. 1 and 2, A is a tubular stock having a foot-block B. C and D are the opposing jaws of a clamp, the lower portions of said jaws, as shown at c and d, being shaped to embrace the piano-pedal from each side and to clasp said pedal between them. These jaws are of a springy nature and are adapted to be compressed or set up to clamp upon the pedal or to be separated in order to relieve them from the pedal by any suitable meansas, for example, by the cross-bolt E, passing through the jaws, and the thumbnut F, seated on the threaded end of said bolt. The jaws C and D of the clamp may be carried by the stock A or by its foot-block B in any suitable manner but in order to adapt the clamp to the necessities of particular cases and to insure a firm and reliable grip the best construction is that here shown namely, one in which one of the jawssay the jaw C-is rigidly carried by the lower end of the stock, while the other jaw D is pivotally connected therewith, so that it may be moved to an angle with the plane of the grippingface of the jaw C.

Any suitable pivotal connection maybe employed, though a practical construction is that here shown, wherein the upper end (1 of the jaw D is curved inwardly and is fitted to turn upon and about the lower projecting end of the stock A, so that it is pivotally mounted thereon, the end of the stock being flanged, as shown at G, against a washer g, which lies under and supports the jaw end. This movement of the jaw enables the clamp to fit those piano-pedals which have sloping or tapering shanks on necks. If the jaws should present only parallel faces, it is obvious that they will not grip a tapering pedal-neck firmly; but by having one of the jaws movable, so as to turn to an angle to the plane of the face of the other, they will grip such sloping necks with along bearing and be firmly attached thereto.

H is a foot-rest which is secured upon the upper end of a stem I, which is telescoped in the tubular stock A, whereby it may be raised or lowered therein. A set-screw J is adapted to hold the stem in any position to which it is adjusted. The foot-rest II is best set upon the top of the stem I at an inclination, whereby the proper and easy slope is provided for the pressure of the foot.

In the collapsed condition of the device, in which the foot-rest is pushed down to its limit, it may be carried conveniently in a satchel and brought out for use when required. It is readily clamped to the pedal, and then by loosening the screw J the footrest H may be raised to the proper point to suit the individual and there fixed. It is readily disconnected from the pedal, if required, or it may be permitted to remain on the pedal without interfering with the nor mal use of said pedal, as it clamps it far enough back to allow the pressure of the foot on the front end without inconvenience.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an adjustable extension for pianopedals, a foot-rest, an elongated bar carried thereby and a clamping device mounted on said bar comprising opposing jaws, with means for setting and relieving them, one of paid jaws being movable about the axis of the 2. An adjustable extension for piano-pedals, comprising a stoek, a olamp carried by the lower end of the stock; and consisting of a jaw fixed thereto, an opposing jaw movable means for setting the jaws together and relieving them, a foot-rest having a stem adjustable in said tubular stock, and means for about the axis of the stock, and means for fixing said stem where adjusted.

setting the jaws together and relieving them, and a foot-rest carried by said stock'.

3. A11 adjustable extension for piano-pedals, comprising a tubular stock, a clamp carried by the lower end of the stock and consisting of a jaw fixed thereto, an opposing jaw movable about the axis of the stock, and

In witness whereof I have hereunto set my hand.
