EXTENSIBLE BOX-COUCH.

SPECIFICATION forming part of Letters Patent No. 777,965, dated December 20, 1904.

Application led January 19, 1904. Serial No. 189,690;

To @LZ- wwm t may aoncern:

neapolis, in the county of Hennepin and State of Minnesota, have invented Certain new and useful Improvements in Extensible Box- Oouches; and I do hereby 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.

My invention relates to folding box-couches, and has for its object to improve the same in the several particulars hereinafter noted.

The invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims, and is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a plan view of the improved .P02 of Fig. 1; and Fig. 3 is a view correspond-l ing to Fig. 2, but showing the couch as folded.

The numeral 1 indicates the rectangular body or box of the couch, the same being supported at its four corners by caster-wheels 2. This box 1 is open at its top and at one side; but the top thereof is normally closed by a hinged rectangular frame or box-section 3, to the top of which is secured the main cushion 4 of the couch.

The numeral 5 indicates a rectangular supplemental frame having secured to its upper portion and supporting a supplemental cushion 6. This supplemental section of the couch is supported and operated bynovel means, which will now be described.

An extensible supporting-frame, made up of end bars 7 and a tie-bar 8, works telescopically into the box 1 through the open side thereof. At their inner ends the end bars 7 are provided with wheels 9 and 10, the former of which run over the bottom of the box 1 and the latter of which engage the ends The bottom of the box 1 at its open thereof.

side is also preferably provided with antifriction-wheels 11, over which the bars 7 run under but slight friction. At their ends the bars 7 are provided with caster-wheels 12, that run upon the floor and support the outer portion of the extensible vsupporting-frame. The supplemental box-frame 5 is supported from the extensible frame by two pairs of folding parallel links 13 14, which links are pivoted to the ends of said box 5 and to the side bars 7 of the said extensible frame. The innermost links 14 have free end extensions 14a and are subject to springs 15, attached to the innermost portions thereof and to fixed projections 16 on the inner ends of the side bars .of the extensible frame. These springs 15 tend to throw the links 14 into vertical positions, as shown in Fig. 2, in which positions their upper end extensions 14 strike stops 17 on the ends of the supplemental box 5.

It is evident that the links 13 and 14 move always parallel to each other and that the supplemental box 5 will be raised and lowered to and from the positions shown in Figs. 2 and 8, being held always in a horizontal position. When the supplemental box-section 5 is dropped outward and downward onto the extensible frame, the said extensible frame, together with the said supplemental box, may

be easily run in under the top 3 4 of the couch proper and entirely into the main box 1; but it should be here noted that even when this is done there is quite a large space for the reception of the bedclothes and other articles left within the box 1 back of the supplemental box 5.

When it is desired to convert the couch into a bed by extending the width thereof, the extensible frame or track 7 8 is of course first drawn out to the position shown in Fig. 2, and then the supplemental box 5 is raised into the position shown in Fig. 2. The springs 15 have not in themselves sufficient tension to raise the supplemental box-section 5, or at least would not ordinarily be so arranged, but are preferably set under such tension as to make it very easy to raise or to lower the supplemental box-section.

To lock the supplemental box 5 in its raised operative position, I provide a pair of latchdogs 18, 'that are pivoted at 19 to the ends of thel supplemental box-frame 5 and are provided with projecting noses 20, which, as shown, work through perforations in the end plates of said box and engage the outer edges ofthe link extensions 14 and cooperate with the stops 17 to hold the links 14 in vertical positions. The latch-dogs 18 are subject to springs 21, that yieldingly press them into operative positions, and they are provided with lateral extensions, to which are attached the ends of a trip-cord 22, which cord, as shown, runs over the guide-sheaves 23 on the outer side plate of the frame 5 and at its intermediate portion passes outward therethrough at 23 to alford an exposed portion 25, that may be taken hold of and pulled to simultaneously release the latch-dogs 18.

A stifening-board 26 extends substantially from end to end of the box 5 and is hinged thereto at 27 and to the side bars 7 of the extensible frame 7 8 at 28. The hinges 27 and 28 are located parallel to the pivot-joints of the links 13 and 14, so that the board 26 is mounted to fold from the position shown in Fig. 2 into the position shown in Fig. 3, and vice versa, by movements always parallel to the said two pairs of links. When the parts are adjusted as shown in Fig. 3, the board 26 stands in a vertical position and closes the outer open side of the box 1, and when the parts are adjusted as shown in Fig. 3 the said board lies in a horizontal position and serves as a sheltl or support for articles placed within the box 1. At all times the said hinged board 26 stitfens and braces the supports for the su pplemental box 5.

From what has been said it will be understood that the device described is capable of considerable modiiication within the scope of my invention as herein set forth and claimed. For instance, instead of arranging the links 13 and 14 to lower thel supplemental box 5 by outward-swinging' movements they might be arranged to lower the same by inwardswinging movements; but this latter indicated construction would require the lifting of the cover or lid of the main box in order to permit the supplemental box to be lowered and moved inward. Hence the construction described and illustrated is preferred.

Other modifications will sugg'est themselves to those skilled in the art, all within the scope of my invention. j

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. The combination with a couch proper and a supplemental couch-section, of an extensible supporting-frame movable into and from the `body of said couch proper, parallel moving links supporting' said supplemental couch-section from,said extensible supporting-frame, certain of said links having free end extensions, and means for locking said links in vertical positions with said supplemental couch-section extended in a horizontal position, comprising fixed stops and cooperating latches operating on said free end extensions of said links, substantially as described.

2. rIhe combination with a couch proper and a supplemental couch-section, of an extensible supporting-frame movable into and out of the body oi' said couch, parallel links supporting said supplemental couch-section from said extensible supporting-frame, and one or more springs applied to said extensible supporting-frame and to certain of said links and, in part, balancing the weight of said supplemental couch-section, substantially as described.

3. The combination with a box-couch having a hinged top, of a supplemental couchsection, an extensible su pporting-frame movable into and out of the body7 of said box-couch through one side thereof, parallel links supporting the said supplemental couch-section from said supplemental frame, and a board 26 hinged to said supplemental couch-section and to said supporting-frame and arranged for parallel movements with said supportinglinks, substantially as described.

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

FERDINAND LINSMAYER.
