IMPROVEMENT IN MECHANICAL MOVEMENTS.

' Specification forming part of Letters Patent No. 118,016, dated August 15,1871.

To all 'whomV it may concern:

Be it known that I, CHARLES W. HURD, of Gomstocks Landing. in the county of lashington and State of New York, have invented a new and useful Improvement in Mechanical Movement; and l do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a topview of my improved movement. Fig. 2 is a side View of the same. Fig.

3 is a detail view of a modified form ofthe handlever.

Similar letters ofreference indicate corresponding parts.

My invention has for its object to furnish an improved mechanical movement for workin g churns, clothes-washers, wool-washers, iulling-machines, clipping-machines, reapers, straw-cutters, sawing-machines, Src., and which shall be simple in construction and eifective in operation; and it consists in the construction and combination of the various parts of the movement, as hereinafter more fully described.

A represents the longitudinal bars ofthe frame, which are connected by cross-bars B, and supported by legs C of suitable length. D are levers, four, more or less, in number, which are pivoted to a bar or shaft, E, attached to the frame A B, and which are kept in proper relative posi- 1 tion by washers placed upon the rod E,between the said levers D. F is a hand-lever, which is pivoted at its central point to the end of the central bar A, or to some other suitable support. To the lever F, at equal distances from its central or pivoting point, are attached two crossbars, G. To the upper ends of the cross-bars G are pivoted the outer ends of the upper connecting-rods H, the inner ends of which are pivoted to the upper ends of the first and third levers D. To the lower ends of the cross-bars G are pivoted the outer ends of the lower connecting-rods H, the inner ends of which are pivoted to the second and fourth levers D, as far below the shaft E as the other rods H are above it. A By this construction, by working the lever F, which may be done by hand-power or by any other convenient power, the levers D will be oscillated. If desired, the lever F may be pivoted to a standard between the two inner levers D, and may be connectedwith the ends of said levers D by staples j", or other equivalent means. This arrangement can be employed when only one or two levers D are to be used. To the upper ends ofthe levers D may be attached, or upon them may be formed, weights I, to increase the working effect of said levers D. J are rubber or metallic springs, secured to the frame-work of the movement in such a position that the upper ends of the levers D may strike against them and receive an impulse from the elasticity of the.

said springs. With the lower ends of the pivoted levers D may be connected the dashers of a churn, the rubbers of a washer, a saw or saws, cutters, or any other tool, which does its work by a reciprocating movement.

By this movement one or more of the levers D may be used, as the work to be done or the power to be applied may render necessary. By this arrangement, also, should any one of the levers or rods fail, it will not affect the operation of the other parts, each of the levers D working independently of the others.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An improved mechanical movenfent, formed by the combination of the horizontally-vibratin g driving-lever F and vertically-vibrating levers D, four, more or less, with each other, substantially as herein vshown and described, and for the purposes set forth.

2. The combination ofthe weightsl and springs J either or both, with the levers D and F, substantially as herein shown and described, and for the purpose set forth.
