JAMES H. YOUNG, OF PA'IERSON, NEW JERSEY.

MECHANICAL MOVEMENT.

Application filed September 8, 1913.

To all whom it may concern Be it known that I, JAMES H. YOUNG, a citizen of the United States, residing at Pat? erson, county of Passaic, and State ofcNew Jersey, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

The invention relates to such improvements and consists in the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification.

The single figure of the drawings is a view in side elevation of my improved mechanical movement, the position of the parts before operation being shown by solid lines and the position after operation being shown by dotted lines.

The principal object of the invention is to accomplish a movement whereby one member is advanced relatively to, another member and is at the same time moved laterally away from, or successively away from and toward, the plane of said other member.

Referring to the drawing wherein the invention is shown in preferred form, 1 is a suitable support upon which a screw-shaft, 2, is rotatively mounted in bearings, 3, longitudinal movement of the screw-shaft being prevented by collars, 4, thereon. The screw-shaft is adapted to be rotated by means of a wrench or handle applied to the angular end, 5, of the shaft.

A pair of diagonal levers, 6 and 7, are pivoted together at 8, intermediately of their ends, the lever, 6, having its lower end pivotally connected at 9 through one of the bearings, 3, with the support, 1, and screwshaft, 2. The lever, 7, is somewhat longer than the lever, 6, and the pivotal connection, 8, is at substantially the middle of the respective levers, each arm of the lever, 7 being longer than the respective arm of the lever, 6. The upper end of the lever, 6, is pivotally connected at 10, with one end of a slide-shaft, 11, which is adapted to reciprocate through a guideway-sleeve, 12, pivotally connected at 13, with the upper end of the lever, 7. The lower end of the lever, 7, is pivotally connected at 14 with a sleeve,

15, which is interiorly screw-threaded to fit the screw-shaft, 2. One end of the longer lever, 7, is shown offset adjacent to the pivotal connection, 14, whereby said pivotal connection, 14, is located at one side of a line extended through the pivotal connectlons, 13 and 8.

By rotating the screw-shaft, 2, in opposite directions, the sleeve, 15, can be moved back and forth along the screw-shaft, 2, and when moved to the left along said shaft, the sleeve, 15, serves to swing upward both levers, 6 and7, and the slide-shaft, 11, while maintaining the slide-shaft, 11, substantially parallel with the shaft, 2. As the parts are raised or depressed in operation, the shaft, 11, slides within the guide-sleeve, 12, the movement of the several parts being lndicated by dotted lines in the drawing. The movement thus accomplished causes the shaft, 11, to be advanced relatively to the shaft, 2, and at the same time to be elevated relatively to the shaft, 2, until the lever, 6, reaches vertical position. If the amplitude of the movement be such as to carry the lever, 6, past its vertical position, the shaft, 11, will be continuously advanced relatively to the shaft, 2, and will at the same time be first elevated and then depressed relatively to the plane of the shaft, 2. By offsetting the end of the longer lever, 7 adjacent to the pivotal connection, 14, substantial parallelism is maintained between the two shafts, 11 and 12, while the parts of the device are permitted to be folded compactly together, as shown by solid lines in the drawing.

For certain purposes of the invention, the sleeve, 15, may be moved in any known manner along a suitable guide to accomplish the movement indicated.

The movement described has numerous applications in the mechanical arts, such as, for example, in elevating guns or launching life-boats.

What I claim as new and desire to secure by Letters Patent is 1. A mechanical movement comprising in combination a pair of shafts; a pair of diagonally arranged levers of different lengths pivoted together intermediately of their ends, one of said levers having its opposite ends pivotally connected with said shafts respectively; and members pivotally connected with the opposite ends of the other of said levers and movable longitudinally of the respective shafts.

2. A mechanical movement comprising in combination a support; a pair of shafts, one mounted upon said support; a pair of diagonally arranged levers of different lengths pivoted together intermediately of their ends, the shorter of said levers having one of its ends pivotally connected with said support and its other end pivotally connected with the other of said shafts; sleeves embracing and movable longitudinally of the respective shafts; and pivotal connections between said sleeves and the respective ends of the longer of said levers.

3. A mechanical movement comprising in combination a pair of shafts; a pair of diagonally arranged levers of different lengths pivoted together intermediately of their ends, one of said levers having its opposite ends pivotally connected with said shafts respectively; and members pivotally connected with the opposite ends of the other of said levers and movable longitudinally of the respective shafts, one of the pivotally connected ends of one of said levers being offset to one side of a line extended through the pivotal connections at its other end and middle.

at. A mechanical movement comprising in combination a support; a pair of shafts, one mounted upon said support; a pair of diagonally arranged levers of different lengths pivoted together at substantially their middle, the shorter of said levers having one of,

its ends pivotally connected with said support and its other end pivotally connected with the other of said shafts; sleeves embracing and movable longitudinally of the respective shafts; and pivotal connections between said sleeves and the respective ends of the longer of said levers, one end of said longer lever being offset and having its pivotal connection at one side of a line extended through the pivotal connections at its other end and middle.

In testimony whereof, I have hereunto set my hand this 28th day of August, 1913.v
