SUPPORT FOR MOVING BODIES.

SPECIFICATION forming part of Letters Patent'No. 501,949, dated July 25, 1893.

Application filed July 25, 1892. Serial No. 441,134. (No model.)

To all whom it may concern:

Be it known that I, VILLIAM J. LANE, a citizen of the United States, of America, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Supports for Moving Bodies, of which the following'is a specification.

In Letters Patent of the United States dated June 2l, 1892, No. 477,558, I have shown and broadly claimed an apparatus, in which a bar pivoted on a base, is connected to an arm in such a manner that when the bar is inclined, the arm is inclined equally but in an opposite direction, so that the free end of the arm, Vmoves in substantially a straight line, and may support a body so moving.

My invention hereinafter set forth, is an improvement in which the same principle of construction is embodied, but with substan# tially different connections, by means of which the bar is maintained in its changing relation to the base, and the arm and bar in their changing relations to each other.

I have illustrated my invention in the accompanying drawings, in which- Figure l represents the invention in perspective. Fig. 2, shows an edge View thereof. Fig. 8, shows a rear elevation.

In the figures, a base of convenient form and representative of any suitable base, is shown at A. It consists of a metal plate, the ends of which are bent inwardly, to form an oset at b, the ends being provided with holes 2, for securing it in place. The recess between the offset and behind the plate, as shown in Fig. l, allows space for the pivoted bar D. This bar is pivoted upon a sleeve held on a bolt d set in the plate, so as to move in either direction in plane parallel with that of the plate, its range of movement being limited only bythe oifsets.

To the upper part or free end of the bar, is pivoted awheel E, bya sleeve held bya bolt e. The wheel carries an arm F, which is firmly secured and bolted to the wheel, the arm and wheel moving together on the bar. The periphery of the wheel is grooved preferably with a double groove, 3, 3. The arm has a hole in its lower or free end, as indicated at 4, by means of which the moving supported or suspended body may be attached.

For convenience of illustration, I represent the device, as supporting a sliding door H, which requires to be moved in a substantially horizontal line, although the movement may be in a slight curve highest in the center, or the reverse. It may be desirable to have the line of movement of the end of the arm,trace a curve slightly higher at the ends, to compensate for the spring of the parts when the bar and the arm are inclined, or extended, when it is desired to carry door or other load in a straight line. It will be understood that for such a door, the apparatus would ybe used in duplicate.

The door or other object is suspended by pivotal connections, with the lower end of the arm or arms, and the distance between this pivot in the lower end of the arm and the pivot of the wheel or segment E (when movement of the suspended body in a right line is required) is the same as the distance between the pivot e and the pivot d: Variations from this equality will give curved lines of movement, in a vertical plane, when bar and arm are moved as above indicated. In order to maintain the bar and arm in these relations and to support them upon the base, I have in this invention providedv direct connections between the bar and the base on which the bar is pivoted; and these direct connections, also maintain the relations between the bar and the arm.

It will be observed that the Wheel E, is a fixed part of the arm F. On the base, as a fixed part thereof, is a circular or nearly circular rim, which for convenience, I call a segment, and have marked it G. Its center is the pivot el. It might bea complete wheel, but the part cut off is not necessary. As shown, it consists of a simple rim of metal, having a flange g, which with the base plate, to which it is fixed, forms a channel orV groove for the rope. These two parts, the arm with its wheel and the base having a circular rim, may be connected in other ways; but as shown, they are connected by a rope (preferably a wire rope). I might use a chain or a thin elastic strip of metal, but the wire rope is better. This rope is connected to both parts as shown. For convenience I use a single piece of wire rope, one
