Description
@initrd 536mm NELSON READ. OF WINCHENDON, MASSACHUSETTS'.
Letters Patent No. 93,004, elated July 27, 1869.
IMPROVED MECHANICAL' MOVEMENT.
The Schedule referred' to in these Letters Patent and making part ol the same'.
To all whom it may concern A -Be it known that I, NELSON READ; of Vinchendon, in the county of Worcester, and State or Massachusctts, have inmented a new and useful Improvement in Mechanical Motion and I-do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part ofthis specification, which represents a side View of my invention.
This invention relates to a new and useful improvemeut in means for transmitting motion from a rotary driving-shaft to two or more rotary counter-shafts.
The object of the invention is to prevent irregularity of motion, hitherto caused in crank-connections by the difiiculty of the crankfinpassing the centres of the shafts.
A B C represent three4 shafts, which are parallel with each other, C being a driving-shaft, from which motion is communicated to A B.
These shafts have crank-pulleys A B C', on one end, and to the wrist-pins E F Gr of these crank-pulleys a curved or bent connecting-rod, D, is affixed.
This connecting-rod is curved .or bent, so that its two arms, a a', which are at opposite sides of the wrist-pin G, willl forni an oblique angle with each other, as shown in the drawing, and the wrist-pins E F G of the crank-pulleys A C', when the rod D is attached to thcm,`have such a position that the two arms of the connecting-rod cannot, both at the same time, be in line with the shafts AB C. This will be fullyunderstood by referring to the drawing, in which the arm a 1s shown in une with the 'sh'afts'A C, while the other arm a is out of line with the shafts B C; hence it will be seen that one 'arm' will assist the other in passing centres, a in the present position of the parts assisting a and a, when, the position of the parts is reversed, assisting at. Y
This invention is'not confined' in its application t0 the three shafts A B C, for two or morel shafts may be connected with either arm of the connecting-rod D.
The invention is applicable to various purposes,` such, for instance, as Singers' sewing-machine, in which the needle and shuttlefshafts are driven from a central shaft, corresponding to C, in the drawing, the needle and shuttle-shafts (corresponding to A B) being driven by gears from C.
Having thus described my invention,
l claim as new, and desire `to secure by Letters Patent- The transmitting of motion from a driving-shaft, C to two counter-shafts, A Br through the medium oi the bent or curved connecting-rod D, made in one piece, and cranks or c'rankpulleys A BC, arranged to operate in the manner substantially as shown and described.
