WILLIAM D. SNYDER, OF OHIbAGO, ILLINOIS.

FOLDING BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 474,868, datedMay 17, 1892.

Application filed January 22, 1891. Serial No. 378,640. (No model.)

, tion of such link connection.

Another objectis to provide in conjunction with such link connection an automatic-locking device for preventing the accidental closing of the bed-frame after being opened.

These objects I have attained by the construction illustrated in the accompanying drawings, in which-- Figure 1 is a vertical section of a closed bedstead of the class mentioned, taken on the line 1 1 of Fig. 3, looking toward the left. Fig. 2 is a like view to that shown in Fig. 1, except that it shows the bedstead open. Fig. 3 is a fragment of a transverse vertical section, taken on the line 3 3 of Fig. 2, looking toward the right.

In the drawings, A designates the stand ard, and B the bed-frame, which are of ordinary construction. On each side of the standard near its base is attached a cleat or rest a for the lowerend of a link a, provided with a rockerbase, which is adapted to rock back and forth upon said cleat, said rocker-base and cleat being preferably provided with teeth, as shown. The top of the link ct is provided with a socket, in which the pivot-pin I), seen red to the plate I) of the bed-frame, can rest and work in opening and closing the bed.

For the purpose of steadying the bed-frame upon the rocking links a I provide on each side a cross-1ink 0, one end of which is pivoted to the standard at c and the other to the bed-frame at c, a washer being interposed to hold said cross-link out of the plane of the rocker-link, so that the two can work without interfering.

The rocker-links carry the weight of the bedframe, and the relation of the parts is such as to produce a slight pull on the cross-links. This means of connecting the standard and bed-frame gives great advantage to the counterpoise D, thus reducing the amount required to counterbalance the bed. It also affords an ease and smoothness in the working of the bed-frame not heretofore attained.

To the side boards of the standard on the inside is attached projecting pieces E, which are provided with anotch e in their rear edges. Below said notch said pieces are beveled, as

jecting outwardly on each side and adapted to strike the pieces E and engage the notches therein. slot 0 in the end of the crosslinks allows the pivots at c enough play to permit the pins e to passover the incline at e and engage the notches When the bed-frame is let down and to be disengaged from said notches by a slight lift at the foot when starting to close it up.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with the standard provided with rests a and bed-frame, of links (1, provided with a rocker-base adapted to Work upon said rests a on the standard and pivoted at their upper ends to the bed-frame, and links 0, pivoted at one end near the front edge of the standard at a point in front of links a, and at the other end to the bed-frame at a point behind the links-a, so as to play across and alongside of the same, as specitied.

2. The combination, with the standard and bed-frame, of links a, supported at the base of the standard and connected with the bedframe, as shown, cross-links O, pivoted to the standard and bed-frame, as shown, a slot 0 being provided at one end to allow slight play of the pivot-pin therein, and projecting notched pieces and pins on the standard and bed-frame adapted to, interlock when the bedframe is let down, as specified.
