JACOB DAVID, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN MECHANICAL MOVEMENTS.
Specification forming part of Letters Patent No. 222,872, dated December 23, 1879 application filed November 7, 1879.
To all whom it may concern:
Be it known that I, J AGOB DAVID, of Brooklin, in the county of Kings and State of New York, have invented a new and useful linprovement in Mechanical Movements, which iinprovementis fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 shows my movement in side view. Fig. 2 is a plan or top view of the same.
Similar letters indicate corresponding parts.
My invention relates to mechanism for converting a rotary motion into a reciprocating motion; and it consists in the combination of toggle-levers pivoted together--one pivoted to a fixed support, and the other pivoted to a movable objectwith a crank mounted on a revolving shaft, and a connecting-rod between the crank and the toggle-levers engaging the cranlcpin and the pivot at thejnnction of the levers, so that while a reciprocating motion may be given to the movable object by a revolution of the shaft, the union and efliciency of the parts is preserved in any position of the toggle-levers, as hereinafter more fully set forth.
In the drawings, the letterAdesignates the toggle-levers; B, the crank, and O the driving-shaft. The toggle-levers A are connected together at one end by apivot, cl, and one is connected to a fixed support, E, by a pivot,f, While the other is connected to a movable object, G, by a pivot, 71. The movable object G consists, in this example, ofajaw in an ore-crusher, of which the fixed support E is a portion of the The crank B is fixed on the shaft 0,
and a rod, I, engaging the crank-pin and the pivot d at the junction of the toggle-levers,
serves to connect the crank with the levers.
When a revolving motion is imparted to the two distinct motions to each revolution of the shaft. By the pivots (if h the parts are kept united in any position of the toggle-levers, and
their efficiency or utility is preserved.
When the toggle-levers are allowedto iest in notches at the pointsdfh, as in the orecrushers now generally used, they are capable of but a very small motion, inasmuch as they are liable to become disunited at those points if moved to any greatextent above and below the center-line.
What I claim as new, and desire to secure by Letters Patent, is-
A mechanical movement for converting a rotary motion into a reciprocating motion, embodying the combination of toggle-levers pivoted together at one end, and at their opposite ends pivoted,respectively, to a fixed support and a movable object, a revolving shaft provided with a crank, and a rod pivoted to the cranks and to the toggle-levers at their pivotal junction, forming a connection between the crank on the revolving shaft and the toggle-levers, whereby the revolving motion of the shaft transmits a continuous reciprocating motion to the movable object connected with the toggle-lever, substantially as described.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 4th day of November, 1879.
