MECHANICAL MOVEM ENT.
SPECIFICATION forming part of Letters Patent No. 268,160, dated November 28, 1882.
Application filed March 523, 1882.
To all whom it may concern:
Be it known that I, BUEL WV. WHITNEY, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
My invention relates to mechanical movements; and it consists in the peculiar construction of the same, as will be hereinafter fully set forth and claimed.
In thedrawings, Figure 1 is a view in elevation of my device as adapted and applied to a sewing-machine. Fig. 2 is a detached view of a part of my device, showing more clearly one manner of constructing the same. Figs. 3.and 4 are detached views, illustrating the connection of the oscillating pitmau and horizontal lever.
A is an oscillating pitmau or lever, which receives its motion from a crank or eccentric imparting the same to a horizontal lever. B, which is provided with a bifurcated end. The lower end of the pitman or lever A is formed hollow and preferably split. Into this hollow end fits a spindle or end piece, 0, which is provided on its lower end with a head, 0, which is preferably made in the form of a cube with its sides a and b curved. I This spindle O is secured in the pitman A in such a manner as to allow it to slide vertically in the same and also allow it to revolve on its axis. One manner of securing it in the above-'inentioned manner is shown in the drawings, which consists in providing the upper end of the spindle O with an annular groove, 0, and providing the pitman A with a set-screw, d, which ("No model.)
engages with said slot c and prevents the spindle from falling out of the pitman, but allows it to move vertically and revolve in said pitman, as hereinbefoie mentioned. The curved sides of the head 0 are placed adjacent to the inner faces of the bifurcated end of the horizontal lever B. Thus arranged a IlllIVGY-Sill coupling is provided between the vertical and horizontal levers A and B, as will be seen. A flat surface is always presented to the bifurcated end in a horizontal direction.
I donot claim broadly the combination, with a vertical oscillating lever, of a rocking or vertically-moving bar and a horizontal lever, as such a combination isshown in patents to DArcy Porter, No. 2482M, of October 11, 1851, and No. 250,169, of November 29, 1881; but myimprovement,as hereinbefore described, affords a simple device for imparting the required motion to the lever B without revolving the lever A.
I claim- The combination, with a vertical oscillating lever formed hollow at its lower end, of a- Witnesses:
