TO ALL WIIOM 1'1 MAY CONCERN:'
Be it known that I, J. S. BIRCH, of the city., county, and State of New York, have invented a' new and improved Adjustable Watch-Key and- I do hereby declare that the following isa full, clear, and exact description of the saine, which will enable others skilled in the art to make and use my invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part'of this spcciication, in which- Figure 1 is a side view of my improved watch-key, partly in section to show the construction.
Figure 2 is a top or end view of the same.
My invention has for its object to furnish an improved key for watches, which may be so adjusted as to lit any watch, whether large or small; and it consists in slitting the barrel of the key diagonally, making the lower part of the barrel cone or pyramid-shaped; and in the combination of a thumb-nut and sleeve with the i barrel of the lcey, the whole being constructed and arranged as hereinafter more fully described.A
A is the barrel of the key, the base of which is made'square in the ordinary manner. The barrel A is slit or divided longitudinally, said slit crossing the said bore diagonally, or from corner to corner, as shown in g. 2. The lower partlof the barrel A is made in the shape of an inverted cone or square pyramid, that is to say, it gradually decreases in size towards the shank or stem a', so that, as the sleeve or slide B is moved up, the parts ef the barrel A may be forced together, or towards each other, so that the barrel may be adjusted to wind the watch, whatever may be the size of its axle. v Upon the shank or stem a of the-barrel'A is formed a screws thread, into which tits the screw-thread cut in the inner surface of the nut O.' The slideor sleeve B, when the inclined part of the barrel A is made cone-shaped, may be rigidly attached to or formed solid with the nut C.;
but when the inclined part of said barrel is made square, or pyramid-shaped, the sleeve or slide B must be made separate, so as to slide or' be pushed up the said part as the said nut is turned upon the stem or shank a. llhe forward end of the barrel A must be made so small that, when the parts are drawn together by the sleeve or slide B, the said barrel will grasp the axle of the smallest watch. It will be observed that by slitting the barrel A diagonally, the said barrel grasps theaxle at its corners, thatisto say, inthe most favorable position vfor the application of power. D is the handle of the key, which is attached to the shank or stem a, and which may he made of any desired size, form, or rnaterial. v
Having thus described my invention, I claim as new, and desire to secure`by Letters Patent A 1. Slitting the barrel A of a watch-key diagonally, substantially as herein shown and described, and for the purpose set forth.
2. Forming the lower part of the barrel A cone or pyramid-shaped, that is to say, decreasing in size towardsI the shank or stein a', substantially asvherein shown and described, and for the purpose set forth.
8. The combination ofthe sleeve or slide B and nut C, one or both, and whether made in one or two pieces, with the slit barrel A of the watch-key, substantially as herein shown and described, andfor the purpose set forth.'
The above specification of my invention signed by me this 15th day of August, 18,67.
' J. S. BIRCH.
