others, to provide a simple, cheapneasily applied and eilicientportable' hand tool for this purpose by which the pins may be readily and quickly cleaned and polished without removing them from their place in the piano.

I provide a device applicable to the socket of any kind or make of a spiral or pneumatic screwdriver or other .well knownimplement, or as easily operated by a'screwdriver, or a handle or other implement, as. may be found most expedient.

The invention is capable of embodiment in a variety of forms, some of the most preferable ones of which *onlv I have chosento show herein.

body the salient features ofmy present 1n-' Allof them, however, em-

vention.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically pointed out in the appended claims. l

The invention is clearly illustrated in the accompanying drawings, which, 'with the numerals of reference marked thereon..form.. p

' tions ofthe tuning a partof this specification. and in which M -Figure 1 is a perspective view showing the manner of use of the implement. Fig. 2 is a substantially central longitudinal section through the implement. Fig. 3 is a detail in elevation, with a portion broken away and parts in section showing another mode of use. Fig. 4 is an elevation showing still another way in which the implement may be used. Fig. 5 is an end view of F ig. 3 with the screwdriver omitted. Fig. 6 is a substantially central longitudinal section showing a modified form of the implement. Fig. 7 is a cross section through the same. Fig. 8 is a view similar to.Fig. 6 showing still another form. Fig. 9 is a cross section through F ig/S with the resilient member in position. Fig. 10 is a substantially central longitudinal section through another form of the invention. Fig. 11 is a cross section on the line 11 of Fig. 10. looking in the direction of the arrows. Fig. 12 is a perspective view of the resilient means for holding the felt core of Fig. 6 in position.

Like numerals of reference indicate like parts throughout the se 'eral views.

.Heferrino to the drawings 1 designates a shank, which as shown in Fig. 2 is adapted for use in connection with a suitable form of chuck such as used on a spiral of pneumatic screw driver, orthe like. It isprovidecl with a body portion 2 having an axial bore 3 in which is received one end of a stem 4 which carries at its other end a disk or thelike 5, which latter is disposed within the cylinder 6 forming an extension of the body portion 2 as seen in Fig. 2. The body portion 2 is provided with an axial chamber 7 with n which is disposed a spiral spring 8 which bears at one end against the disk 1 5 and at its other end against a shoulder or wall 9 at the end of the chamber 7, all as clearly shown inFig. 2. Within the cylinder 6 is a core or. tubular body 10 of some suitable material, such as felt or composition wire brush, held in place against endwise and rotary movement therein in any suitable manner, as by screws or the like 11 as seen in Fig. 2.. The inner end of this core abuts against the disk 5 asdoes also a polishi ingpad 12 which is seated in a socket in the f inner end of the core 10 so that while it may be compressedto a certain extent it is held against displacement by the core 10.

Fig. 1 shows the mode of use of the implement above described... The exposed porpins'13 are to be cleaned andpolished. The implement is applied as shown, the end of the pin being received Within the core 10 and as pressure is exerted on the implement toward the pin the polishing pad will be forced inward against the tension of the spring to cause the pad to press tightly against the head of the pin, and the core is also caused to tightly embrace the pin so that when rotary movement is given the implement the sides and end or head of the pin will be quickly cleaned. Oil, polishing or abrasive material or any chemically treated fibrous or compo sition metal brush may be placed within the core 10 to aid in cleansing and polishing the pin. When pressure is removed from the outer end of the implement the spring 8 tends to give an outward impetus to the device to aid in its removal from the pin.

In Fig. 3 I have shown the implement with its shank 14 provided with a longitudinal socket 15 for the reception of a screw driver or the like 16 by means of which the implement may be operated. This shank is further provided with the transverse opening 17 through which may be placed a rod or other device by which the implement may be rotated.

In Fig. 4 the implement is shown as pro vided with a rounded portion 18 in which is held a cross rod 19 which serves to rotate the implement.

Other means than the screws shown in Fig. 2 may be employed for holding the core in position; for instance, as shown in Fig. 6, I may sometimes use a cage 20, composed of the rings 21 and 22 and the spring bars 23 connecting them; these bars are bowed between their ends as shown and serve to compress the core so that it will closely embrace the pin when the implement is applied thereto. They serve also to prevent endwise displacement of the core.

In Fig. 8 I have shown the interior of the cylinder 6 as spirally roughened as at 24: the serrations engaging in the core 10 as seen in Fig. 9 to hold the core in place.

In Fig. 10 I have shown provision whereby the implement may be made to operate on more than one pin at the same time. In this form there is shown, in addition to the structure above outlined, a brush or brushes for operating upon adjacent pins while the core is applied to a pin and the implement operated. The cylinder 6 is provided with a longitudinal slot 25, which may be present in any or all of the other forms so that a brush may be used in conjunction therewith,

in which is received a screw 26 holding one end of a fiat spring 27 the other end of which has an offset portion 28 to engage the end of the cylinder and hold the spring against accidental displacement. The end being applied to these pins later inv the same way as to the pin as above described. When it is desired to use the implement without the brushes 30 the sleeveis readily removed by disengaging the offset endof the spring from the end of the cylinder when the brush can be readily removed with its cylinder and set aside for future use. i

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed as new is z.-

1. A polishing implement comprising a shank, a tubular polishing member therein, means for holding the two parts in fixed relation to each, other, and a longitudinally movable spring-pressed pad coacting with the polishing member.

2. A polishing implement comprising a counterbored shank, a tubular head carried thereby, a stem disposed Within the counterbore, a disk carried by the stem and disposed within the head, a spring within the counterbore and exerting outward pressure on the disk, a tubular polishing element held within the head, and a polishing pad held in engagement with the inner end of the polishing element by the disk.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM EDWARD JONES.
