LORENZO D. WEBBER, OE DEEPRIVER, CONNECTICUT, ASSIGNOR TO HIMSELF AND S. W. SHAILER, OF SAME PLACE.

Leners Patent No. 105,281, camz my 12, 1870.

The Schedule referred to in these Letter Patent and making part of th same- To all whom it 'may concern:

Be it known that I, LORENZO D. WEBBE'R, of Deep River, in the town of Saybrook, in the county of Middlesex, in the State of Connecticut, have invented an Improvement on the Machine for Separating the Keys of Pianos and Organs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making part of this specication, in which- AFigure 1 is a perspective view ofthe machine, with 'my improvement attached, and

Figure 2, a representation of a key-board with keys, as laid ont for separation. y

The machine is constructed to separate the keys by the belt-saw S, which runs in the direction indicated by the dart, through the table T, upon which, heretofore, the key-board was placed, and the keys laid out thereon presented to the saw for separation by sliding the key-boardl on the table.

My improvement consists in providing the machine f ivith'a slide to carry and guide the keyboardand furnishing the slide with a straight-edge, or guides equivalent thereto, under which each traced key lmay be passed, and each aligned with the straight-edge so as to be separated by the saw when the slide is pushed forward. l

The slide maybe substituted for that part of the table upon which the key-board was formerly placedor, applied thereon, as illustrated in the drawings, in which- `A represents the slide, and

B the straight-edge.

The slide is made to move parallel with the blade lof the saw by means of a groove, E, cut across the table, into which a corresponding tongue, E', is itted and attached to the bottom of the slide.

I adjust the straight-edge close to the saw, give it an elevation suiicient forthe key-board to pass under it, and fasten both ends to the slide.

C represents a platform attached to the table, to prevent the keysfrom falling. A

The slide is to be drawn back to receive the keyboard, and the key to be separated passed under the straight-edge, and aligned by it for the saw. Then', by pushing forward the slide withone hand, and holding the key-board firmly onto the slide with the other, the key will be separated and rest upon the platform U.

The process of separating piano and organ-'keys has necessarily been a slow one, for the want of some reliable guide which'would meet all of thevexigencies arising from divergent lilies, caused by breaks, and from the dilerent widths of the keys, which want my .improvement so far supplies as to enable a given" amount of work to be done in one-half of the time it was formerly, and by its use the keys are sawed very staight and even, by which the labor of finishing them is reduced, and the spaces, which have heretofore been so large as to give much trouble in attaching the action, are made as narrow as it is desirable they should be, and the key-board is much better when iinished.

I disclaim all parts and combinations of the machine abovedescribednot hereinafter'claimed as my invention. l y What Iclaim as my invention, and desire to secure by Letters Patent, is-

The combination of the slide A, provided with a straight-edge, B, with the beltsaw S.
