United States Patent Patented Jan. 8, 1963 3,072,006 COVERS FOR SMALL ORGANS R PIANGS Fred S. Jurkowski, 51 Ewing Road, McKees Rocks, Pa. Filed Aug. 8, 1961, Ser. No. 130,172 1 Claim. (Cl. 84183) This invention relates to new and useful improvements in covers for small organs or pianos that do not have built-in covers to protect the case and operating mechanism from dust and dirt, and it is among the objects of the invention to provide a replaceable cover which shall be applied between the end walls of a keyboard, the cover having a mounting bracket with yielding engaging faces that will not mar the finish of the sides of the keyboard.

It is a further object of the invention to provide such -a cover of a design that it may be fabricated from fiberglass cloth or other materials and adapted to be rolled up and stored away when not in use.

The invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts, and in which:

FIGURE 1 is a view in perspective of a piano or organ keyboard cover embodying the principles of this invention;

FIGURE 2 is a cross-sectional view, partially in elevation, taken on the line 2-2 of FIGURE 1; and

FIGURE 3 is a transverse section taken along the lines 33 of FIGURE 1.

' In the drawings, the numeral l designates a tube of aluminum, plastic or other lightweight material provided.

at one end with a rubber tip 2 and with a telescoping tubular portion 3 at the other end that is also equipped with a rubber tip 4. The tube 1 is provided with a stop pin 5 against which a coil spring 6 rests, the coil spring at its other end abutting the end of the telescoping tube 3. A stop pin 7 extends into a slotted portion 8 of the telescoping piece 3 and the latter is movable into and out of the tube 1 a distance corresponding to the length of the slot 8. A tube 9 of similar material as the tube 1 and of the same dimensions lengthwise, is disposed in the casing of a flexible cover, the casing being made by overlapping the end 10 of the cover which is provided with a similar casing at its other end to receive the tube'l. The casings may be glued or cemented to the tubes to permanently fix their position against' axial displacement. As shown in FIGURE 2, the cover material may be split in the center and the tubes 1 and9 may be terminated in the center and telescopically mounted over a central tube 11 with which they have sliding engagement. The cloth material may likewise be provided with a splicing piece of cloth designated by the numeral 12 in FIGURE 2 which overlaps the ends of the cloth sections, as shown,

so that the cover may be contracted and expanded to vary its width to different sized organs or piano keyboards.

In operation, the extensible end member 3 is'collapsed against the tension of the coil spring 6 and the rubber tip 2 is held against the end wall of a keyboard. The cover is then laid on the keyboard and the member 3 is released so that the rubber tip 4 engages the other end wall of the keyboard. The tension of coil spring 6 will firmly hold the rubber tips 2 and 4 in gripping engagement with the end walls of the keyboard. The end of the cover is then pulled over the keyboard and allowed to lap over the front end of the organ or piano to prevent dust entering into the keyboard. The cover cloth, which is generally desinated by the numeral 10a, is then adjusted to the width of the keyboard by adjustment of the telescoping tubing and the overlapping cloth portion 12. Once this adjustment is made, it is of course set for all time.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the'art that various modifications may be made in the details of construction without departing from the principles herein set forth. j

I claim: I p A snap-on cover for the keyboards of organs, pianos and the like, comprising a flexible cover having casings provided at the ends thereof, a tubular member inserted in the casing at one end of said cover having a slidable tubular member at one end mounted for telescopic movement within said first-named tubular member and having a spring for biasing the same to its extended position,

' said slidable member having a slot engaging a pin secured to said first-named tubular member to limit its movement and said first-named tubular member and telescopic tubular member having rubber tips for frictionally engaging the sides of a'keyboard, a tubular structure disposed in the casing at the other end of said cover member consisting of a central tube having a pair of tubular members in sliding engagement with the outside of said central tube to be adjustable to the Width of the keyboard, said cover member having an overlapping portion of a width to correspond to the distance of movement of said last-named slidable tubular members to adjust the width of the cover to correspond tothe adjusted position of said tubular members.
