SPECIFICATION forming' part of Letters Patent No. D`r'89,1'7'3, dated May 9, 1905. Application filed June 30, 1903. Serial No. 163,699.

To all wle/0711, t may concern.'

Be it known that I, AARON RUDNITZKY, a citizen of the United States, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented a certain new and useful Improvement in EXtension-Bedsteads, of which the followcot-bedsteads, wherein I have combined the several parts in a way to permit of an expansion and contraction adjustment to enable the structure to be used as a single bed or as a double bed.

One of the features of my invention resides in a toggle connection between the members or sections of an extension-bedstead, said toggle connection affording a means for limiting the expansion movement of the members. With this toggle connection is associated means for supporting the links thereof and the inner side of the slidable member of the cot, said toggle connection being adjustable with said slidable cot member.

Another feature of the invention consists in the arrangement of the toggle devices in a way which permits the slidable cot member to be withdrawn or separated from the main cot member. Thisy removable member is equipped with foldable legs, which are connected pivotally thereto in order that the legs may be unfolded on the withdrawal of the member. The member is also furnished with foldable latches, which are adjustable into locking relation to the foldable legs for holding them firmly in their unfolded positions, thus enabling the removable member to be used as a separate cot, whereby the bedstead may be adjusted to serve as a double bed, or it can be separatedl for the members to be used individually as independent cots.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the novelty will be pointed out in the annexed claims. Y

In the drawings, Figure 1 is a plan view of an extension-bedstead constructed in accordance with mji invention and showing the members folded. Fig. 2 is a similar view with the members drawn out for use as a double bed. Fig. 3 is a cross-section of the bedstead adjusted as in Fig. 2. Fig. f1 is a plan view of another form of the bedstead, and Fig. 5 is a cross-section of the bedstead of Fig. 4. Fig. 6 is an end view of the removable member of the bedstead, showing a leg and a latch adjusted for service. Fig. 7 is a view of the member shown by Fig. 6 with the leg and latch adjusted to their folded positions.

Like characters of reference denote corresponding parts in all the figures of the drawings.

The extension-bedstead of my invention consists of the members A B, of which the member A is somewhat larger than the member B, and the latter is fitted slidably to said member A. Said member A is intended to remain stationary during the adjustment of the parts, and it consists of end frames forming the legs a and the longitudinal side bars a, said parts being made, preferably, of angleiron and united together in a substantial way. The slidable member B consists of top rails two legs L', and a single longitudinal rail Z2", the parts being also made of angle-iron and united substantially to produce a structure which is open at its inner side. The slidable member B is provided at said open inner side with a longitudinal brace-bar C, having its end portions bent upward and fastened to the top rails I) of the member in an approved way, said brace-bar lying in a plane below the top rails, as shown by Fig. 3.

It will be understood that the main member A is provided with four legs, one at each corner, whereas the member B has only two legs, at the outer side thereof. member B is fitted on the member A for its brace-bar C to lie within the limits of said member A, and this brace-bar C is arranged to rest and to slide upon one or more crossbars I), which are arranged transversely across the main member at suitable points and are fastened to the side bars a thereof.

One of the important features of this in vention consists in the employment of toggle connections between the main and slidable members. Said toggle connections consist of the links E E and the links F F, the links E F of each pair being pivoted at e to the outer Said slidable side rails aof the member A, while the other links, E F, of the pairs are pivoted atf to the outer singlevrail Z2" of the member B. The links of each pair are pivoted together' at g, and the two pairs'of links are adapted to eX- tend inwardly toward each other, as shown by Figs. l, 2, and 4:. The lin-ks lie below the brace-bar C ofthe member B, and this bracebar is adapted to travel or slide on the links, as well as on the rail D, when the member B is adjusted. The links serve, primarily, to hold the members A B in proper relation, and they also act to limit the outward sliding adjustment of the member B. Another feature of my invention consists in the employment of movable legs G, which are connected at their upper ends to the two pairs of links, said legs being each attached to the links of one pair at the point where the links are pivoted together. The legs of the members A B and the legs G are provided with rollers or casters, and the legs G serve as the means for supporting the pivoted ends of the togglelinks, as will be seen by reference to Fig. 3.

In some cases I may dispense with the legs Gr as a means for supporting the pivoted ends of the toggles, and in this event the toggles are arranged to rest on the cross braces or rails C, which are fastened to the memberA in positions below the toggles and in a way for the toggles to rest thereon when the members A B are extended or folded. The links forming the toggles may also be connected detachably to the members A B by the cmployinent of suitable pivotal bolts. Such construction allows the member B to be withdrawn or separated from the member A in order that the two members may be used independently as separate cotbeds. Under these conditions I provide the separable member B with foldable legs I, which are provided with casters and are connected pivotally, as at 71 to the top rails b at points close to and within the brace-bar C. (See Figs. 6 and 7.) These legs I are adapted to fold upwardly alongside the rails b of the member B, as in Fig.`7; but when the legs are unfolded downwardly for usc they are held in their operative positions by the latch-bars J. The latchbars are pivoted at j' to the rails b of the member B, and at'their free ends the latch-bars are provided with notches j', adapted to be fitted over studs or pins f2, which are fastened to the legs I. These legs and the latches of the memberB may be fitted compactly Within the angle-iron top rails thereof in order that this member may have the slidable relation to the member A for service in connection therewith as a double or extension bed, and in this event the member B is provided with the brace-bar C, and it may have the toggles connected therewith in the manner heretofore described. At the same time the member B is capable of adjustment in a way to separate or withdraw it from the member A, and when so separated the legs I of said member B may be unfolded, and they are fastened securely in their active positions by the latch-bars. This member B can now be used to form a cot-bed separate from or independently of the member A, thus providing a single structure which may be used or employed as a single bed when the member B is closed relatively to the member A, as a double extension-bed when the member B is drawn out, and as two separate beds on the separation of the members A B and the legs I are unfolded and latched. Y

It is thought that the operation and advantages of my-iniproved structure will be readily i understood from the foregoing description,

taken in connection with the drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. An extension-bedstead comprising two nested sections, one having four legs and the other having two legs, a drop-bar secured to the legless side of one section, and pairs of toggle-links, each pair being pivoted together and pivoted to the respective sections, said links being arranged to rest on a part of one of the sections, and the drop-bar being adapted to rest on said links.

2. An extension-bedstead comprising two nested sections which are slidable one upon the other, a track-rail on one of the sections, a drop-bar on the other section, and pairs of toggle-links, each pair being pivoted togetherand also pivoted to the respective sections, said drop being arranged to rest on said links and on the track-rail when the sections and links are extended.

3. A bedstead consisting of a main member having four legs, a slidable member having two legs and a longitudinal drop-bar at its inner side, and toggle connections between the respective members, said toggle connections lying in a horizontal plane between the drop-bar and the side bars of the main member.

4'. A bedstead consisting of main and eX- tension members fitted slidably together, a cross-bar on the main member, a drop-bar on the inner side of the extension member and arranged to travel on the cross-bar of the mainmember, and toggle connections between the two members and resting on theside bar of the main member when the extension member is drawn outwardly.

5. An extension-bedstead comprising two` vfitted slidably to the main section, pairs of links pivoted to the respective sides of the main and slidable sections for limiting the outward movement of said slidable section, and legs connected to the respective pairs of links adjacent to the pivotal connection be- IOO IIO

tween the links; said legs supporting the links when unfolded on the lateral movement of the sliding section and adapted to lie below the overlapping portions of the main and sliding sections.

6. An eXtension-bedstead comprising two nested sections adapted to carry fabrics or bed-bottom sections arranged in different horizontal planes-one bedstead-section having four legs and the other two legs, a pair of links connected to the respective sides of the bedstead-sections for limiting the sliding movement thereof, and a shiftable supportingleg pivotally connected to said links at the point of connection between them; said leg being adapted to lie below the lapping sides of the two sections when said sections and the links are unfolded.

7 An eXtension-bedstead comprising two nested sections, one being slidable on and removable from the other section, foldable legs pivoted to the removable section near one side thereof, braces each having a permanent pivotal connection with the removable section and arranged for interlocking engagement with one of said folding legs, a projection on the removable section for receiving the end portion of each brace when folded, and a stud carried by each brace in position to fit below and to hold the companion leg in its folded position; each leg and brace being foldable on separate pivotal connections with the section, and each brace holding, by its stud, the companion leg in the folded position thereof.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing' witnesses.
