SPECIFICATION forming part of Letters Patent No. 767,059, dated August 9, 1904.

Application iled December if, 190].. Serial No. 84,638. (No model.)

To n/ZZ 'll/71,0771, 'it 777mm/ con/cern.'

Be it known that I, Ti-i'nononn Hausen, a citizen of the United States, residing' at Chicago, in the county of Cook and State of llli nois, have invented a new and useful Improvement in Sofa-Beds, of which the following :is a specification.

My invention relates particularly to a locking device for the swinging' leafl of a sofa-bed;

and my primary object is to provide a simple automatic lock of this character capable of ready manual release.

The accompanying drawings illustrate my present improvement in connection with a sofa-bed having' other features of novelty, which are fully described and claimed in my application of even date, Serial No. 84,639.

In the drawings, Figure 1 represents an end View of asofa-bed equipped with myimj'irove ments; Fig. 2, a broken plan view of the saine in the extended or bed form; Figa and 1-, detail views of a caster connection employed, Fig'. if being taken as indicated at line 4f of Fig. l; Fig. 5, a broken section taken as indicated at line 5 of Fig. 8 and looking toward the inner side of an end of the sofa-bed, showing the rear leaf of the sofa-bed in a vertical position; Fig. 6, a similar view showing the rear leaf in the horizontal position; Fig. 7, a similar view showing the rear leaf in a depending vertical position; Fig'. 8, an enlarged broken section taken as indicated at line 8 of Fig. l and looking' toward the rear; Fig. 9, a plan sectional view, diagrammatic in its nature, taken as indicated at line 9 of Figs. l and 8; and Fig. 10, a section taken as indicated at line 10 of Fig'. 9 and showing the manner of supporting the lever employed in the locking mechanism.

'lhe invention is here illustrated as applied to a sofa-bed of steel construction.

A represents a seat-frame, supported. on end standards A, B a rear swinging' leaf connected with said seat-frame, and C a front swing'ing leaf connected with said seat-frame. The leaf C may be swung' from a vertical de pending' position to a horizontal position, as indicated by the dotted lines in Fig. l, and secured in said position by means of a lock D,

forming the subject-matter of my above-mentioned application.

My present invention is confined. to a lock lli] for the leaf B and to an improved caster connection F with which the sofa -bed is equipped. The seat-frame A comprises, preferably, an angle-iron rt at each endof the sofabed, (one only being showin) while cach standard A is preferably formed with uprights a' ai and a transverse base angle-iron ai. rlhe angle-iron a has a downturned wing or flange afl and an intnrned wing or flange at. ends the flange e is cut away, and the projecting ends of' the flange a." are curved inwardly to afford spring-metal retaining-sockets a for the Shanks of the casters. These sockets are of somewhat less diameter than the caster-shank and serve to hold the latter firmly in position after insertion. The end standzn'ds A' are joined by angle-irons 7), con

necting corres pond ing upright members a' and ai, suitable braces f /Xi being provided.

The locking device E comprises links c, joined by pivots c to the end members of' the leaf B and passing' at their lower portions through slots c2 of the inturned flanges of the upright angle-irons a, and spring-held locking-bolts d, joined by connections d' with a lever (Z2 on a pivot d, said lever being' actuated by a cord or wire (Z, projecting through a perforation in one of the uprights a and terminating in a ring or handle d". As shown in Fig'. l0, the pivot d is supported from the rear angle-imm /J by means of a small angle d, con nected with the depending wing or flange of the angle-iron The pivotal point d is preferably at or near the longitudinal'center of the soi"abed, as may be judged it'romFig. 9. The bolts Z pass through guides afforded by the downturned ends of Lil-shaped ironsj', Figs. 8 and. 9, secured to the horizontal flange of the rear angle-iron Sprinig'coilsyLal tend nor n'ially to thrust said bolts outwardly. rFhc lower ends of the links c, assuming' them to be in the position indicated in Fig. 5, are curved forwardly, upwardly, and Inicluvardly and terminate in shoulders l(y. Said links are provided at their free ends with bolt-receiving perforations y y, corresponding, respectively,

with the locking positions of Figs. 5 and 6. Then the leaf B is'depressed, as shown in Fig'. 7, the outer ends of the bolts (Z press against the inner' sides of the links, but do not lock the links. As shown in Fig'. 9 particularly, the flanges of the upright ang'le-irons af, which are parallel with the ends of the sofa-bed are provided with perforations which receive the eX- tremities of the bolts Z when the latter are eX- tended. It is usual in sofa-beds of this general type to cover the whole frame, including' back, seat, and front leaf, with a spring-held wirenetting adapted to receive a suitable mattress.

' A portion of such a netting is shown in Fig. 2,

where the width of the device when in the form of a bed is shown.

The manner of operation of my improved locking' device will readily be understood from the foregoing' description. The leaf B may occupy the position of the full lines in Fig. l, the horizontal position indicated by dotted lines, or the vertical position indicated by dotted lines. In the vertical depending' position of the leaf B, as illustrated in Fig'. 7, the outer extremities of the bolts Z simply bear against the inner surfaces of the links c. IV hen the leaf B is raised to a horizontal position, the bolts enter the perforations g2 of the links c, thereby locking the leaf in the horizontal position. Yhen it is desired to move the leaf from a horizontal position to either the upright standing' position of the full lines of Fig. l or the vertical depending position of the dotted lines in Fig'. l, this can be done by pulling' upon the wire CZ4 by means of the ring' (Zand thereupon moving the leaf in the desired direction. When brought to the position of Fig. l, the bolts enter the perforations g of the links c, while the shoulders g abut against the front surfaces of the inturned flanges of the upright angle-irons d, firmly locking the back-frame against rearward movement. Tith this construction it is possible to avoid lost motion when the back-frame B is in the standing position. Thile the lever Z2 is here shown pivoted to swing' in a horizontal plane, it will readily be understood that it may be adapted to swing in a vertical plane instead.

Changes in details of construction within the spirit of my invention may be made. Hence no undue limitation is to be understood from the foregoing detailed description.

I/Vhat I claim as new, and desire to secure by Letters Patent, isv

l. In a sofa-bed, the combination with a suitably-supported seat-frame, an upwardlyextending swinging leaf pivotally connected therewith, a link pivotally connected with said leaf above the pivotal point thereof and having a forwardly, upwardly and rearwardly curved lower end located beneath said seatframe, a stationary guide, a manually retracted, yieldingly-held bolt for lockingly engag'ing said link at a given point, and a stationary shoulder engaging the lower extremity of said link above said bolt.

2. In a sofa-bed, the combination with a suitably-supported seat-frame, and an upwardly-extending swinging leaf pivotally connected therewith and constructed to swing to a vertical depending position, of a link pivoted to said leaf above the pivotal point thereof and having a substantially straight upper portionand forwardly-curved lower end located beneath said seat-frame, said link being provided with two locking-shoulders corresponding, respectively, to the vertical and horizontal positions of said leaf, a stationary guide, and a manually -retractech yieldingly -held locking-bolt serving to engage the appropriate one of said locking-shoulders, according to the position of said leaf.

3. In a sofa-bed of the character described, the combination of end standards having rear upright angle-irons with inturned flanges provided with slots, an upwardly-extending pivoted leaf, links pivotally connected with the ends of said leaf and having forwardly-curved lower ends extending through said slots and provided with locking-shoulders, and manually-retracted spring-held locking-bolts engaging' said links.

4. In an article of the character described, the combination with the supports thereof, of horizontally-disposed base members comprising ang'le-irons each having an inturned Iiange and a downturned flange, the inturned Bange being' cut away at its ends and the projecting extremities of the downtui'ned {iange curved inwardly to afford a caster-socket. l
