GEORGE M. LORTZ, OF UTIOA, NEW YORK.

M ETALLIC COT-BEDSTEAD.

SPECIFICATION formngpart of Letters Patent No. 431,602, dated July 8, 1890.

To all whom it may concern.-

Be it known that I, GEORGE M. LORTZ, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Metallic Got-Bedsteads; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference `being had to the accompanying drawings, and

to the letters of reference marked thereon, which form a part of this specification.

The special object of my invention is to make a metallic cot-bedstead whose head and foot pieces shall automatically lock to the body or frame and when unlocked fold beneath it, as hereinafter described.

Figure l of the drawings is a bottom perspective view of my bedstead; Fig. 2, a longitudinal vertical section, and Fig. 3 a vertical cross-section.

In the drawings, A represents the body or frame of my bedstcad, consisting of the four angle-irons a a a. d', the former being the sides and the latter the cross-pieces at the head and foot. The side pieces a a have the concave angle underneath the frame A, and the cross-pieces c a have the concave angle on the top of said frame. The horizontal sides of the angle-plates a d are riveted together, while the other sides of plates a project down perpendicularly and those of plates ct extend upwardly in a vertical plane.

The head and foot pieces B B are formed of narrow flat plates b, bent at b b', so as to form perpendicular leg-posts b2, and braced by the spacing-rods b3 I# b5. To the rod b3 and the inside of the sides da are pivoted the connecting-bars C C, while to the braces a2 and the inside of the end pieces B B are pivoted the springs Dl D, which are provided with the projection d, bent at d CZ', so as to be pressed out as they pass up through holes a3 in the sides a and then spring over the top of said sides, thus automatically locking the end pieces B B to the frame A, as clearly shown in Fig. 3 of the drawings.

In order to close the bedstead, I take hold of each side and press inwardly ,against the springs D D with my thumb, while at the same timeI slightly raise the sides a a. Then the end pieces Will readily disconnect from the sides and fold under the frame A.

By means of an angle-plate E at one end of the bedstead and two straight plates F F, the latter riveted to plate E andto one of the angle-plates a a', I hold securely the ends of a steel-wire mattress G. One plate F is made fast to the angle-plate a and the other to the angle-plate E.

The plates E F are provided with female threads to receive the adjusting and straining screws I-I H, which are swiveled in the angle-plate a', so as to stretch the mattress G as much as may be desired at any time.

Having thus described all that is necessary to a full understanding of my invention, what I claim as new, andvdesire to protect by Letters Patent, is-

A cot-bedstead having the angle-iron sides a a, with holes a3 co3 near their ends and connected by the rods a2 a2, in combination with head and foot pieces B B, having cross-rods b3 b4 b5, the said sides a a and pieces B B being connected by the pivoted bars O C and pivoted springs D D, and said springs being provided with projections d d, adapted to pass up through holes d3 in the sides d and by means of the" inclines d to spring on and oit' the sides a, as described.

In testimony whereof I afiix my signature in presence of two witnesses.
