MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 248,775, dated October 25, 1881.

Application filed September 1, 1881.

To all whom it may concern Be it known that I, LEWIS NEWTON MER- RIMAN, a citizen of the United States of America, residing at Dixon, in the county of Lee and State ofIllinois, 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 willenable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters or figures ofrel'- erence marked thereon, which form a part of this specification.

My invention relates to devices for transmitting the motion of windmill-shafts to attached machinery and for application to other machinery for which it may be adapted; and it consists in the construction and arrangement of its parts, as will be hereinafter set forth.

In the accompanying drawings, which fully illustrate my invention, Figure 1 is a side elevation, and Figs. 2, 3, 4, and 5 are detail views, of the operating portions of the device.

A A are the supporting-stanchions, having braces a a,as shown. To their tops is secured the flat disk a upon which rests the fan-shaft and transmitting device, hereinafter to be described. Operating in an annular groove in thedisk is theringa to opposite sides of which are secured the bearings (F, in which is journaled the shaft to, as shown. The ring a is held in position by the keeper a which is bolted to the disk a Placed around the shaft a are the circular shouldersbb,betwcen which is the intermediate shoulder b. Pivoted between the shoulders at points at right angles to each other from the center of the shaft are the boxes 12 They are constructed in separate parts secured together around the pivotpins b by the bolts I), placed within suitable recesses in the ends of the boxes, as shown in Fig. 2. Y

B B are the connecting-rods. Their upper ends are enlarged, and have formed upon their tops plane surfaces, upon which traverse the boxes N, as shown. These surfaces are wedge shaped, and fit corresponding grooves in theboxes 11 To the upper sides of the rotlsB B are bolted (No model.)

the slotted connecting-links D to the tops of which are bolted the straps I). The lower ends of the straps correspond with and'are placed parallel to the upper ends of the rods B, and also act as ways upon which move the boxes b Secured to the braces a are the sills e 0, upon whichisjournaled the shaftf, which has keyed to its outer end the pulley 9. Upon the shaftj are placed shoulders, and sliding boxes, as hereiubefore described, upon the shaft a. The connecting-rods B B, which connect the shafts, are divided into upper sections. ef, and lower sections, 0 as shown. Formed in the section 6 is the piston g, which operates through the hollow ball upon theend of the section f, and through a guidehole in the brace to. Its lower end forms a ball-aud-socket connection, 0 with the section 0 Upon thelower end of the sectionf isformed the hollow ballg ,which is embraced by a socket, 9 upon the upper end of the section P. This section also has a piston formed in it, which operates through a guide in the brace a.

Upon either end of the shaft a is the windwheel, and upon the pulley g is placed a belt to connect it with the machinery to be driven.

A crank may be used instead of the pulley, if desired.

Bythis construction and arrangementof the connecting-rods B B, shoulders I) b and b, and sliding boxes b upon the shafts a andf, I secure a device for transmitting and changing the direction of motion, in the operation of which there can be no dead-center upon either shaft, and by the operation of the rod-sections in their respective ball-and-socket connections the shaft a can turn upon the disk a to any angle with the shaftf without interfering with its action. As will be seen, the rods B B have no lateral motion, as is the casein connectingrods of ordinary construction and operation.

I do not confine myself to the use of this transmitting device upon windmills, but protransmitting device composed of the sliding I 3.
