COUCH-BED.

Application filed December 5, 1911.

To all whom it may concern:

Be it known that I, CLAnuNoa H. YOUNG, a citizen of the United States, and a resident of Boston, in the county of Suifolk and Commonwealth-of Massachusetts, have invented certain new and useful Improve ments in Couch-Beds, of which the following is a full and exact description.

This invention relates to that type of couch beds wherein one bed-section is mov able away from and back upon a second section in order to convert a single bed or couch into a double-width bed, and vice versa; and my improvements pertain to the means for enabling the movable section to be controlled by foot-pressure.

In the drawings forn'iing part of the specification, Figure 1 is a perspective view of one terminal portion. of a couch bed provided with my improvements. Fig. 2 is a plan view of the treadle. Fig. 3 is a sectional elevation on the line X-X in Fig. Fig. 4 is a plan view of the pivotal portion of the treadle, Figs. 3 and 4 being on a larger scale than the others. Fig. 5 is a detail view of the spring .counterbalancing the movable section. Fig. 6 is a perspective View of the abutment for said spring.

Referring first to Fig. 1, the reference numerals 1,'2 and 3 designate the members composing the end. frame of the stationary 4; and 5, the members of the Specification of Letters Patent.

end frame of the movable section of the.

couch bed; the mattress sections (3, 7 being attached to the frame-members 3 and #1 respectivel Each end of the movable section is, in the form of couch bed illustrated, conthe stationary section by means of parallel arms 9, 10; the arm 9 being pivoted at the points 11 and of the arm 10 is pivoted at 18 to the endframe member 4-. The lower end of said shaft 1st which has bearings in theframe-mcmbers 2, Said arms 9 and 10 are duplicated at the other end of the bed-sections, and between the two arms 10 is located a bar 15 by means of which said arms are held against'the tension of. the mattress section 7. mounted onthe rock shaft 14. close beside the arm 1O at one end of the couch bed, is the double trcadle 16 having at each extremity a foot piece 17. At the side of the arm opposite to said treadle, is a plate 20 rigidly connected to the treadle by studs 21 and also loosely mounted on the extended 12, while the upper end i l l Patented July 2, 1912..

end of said rock shaft. These studs are so positioned that when the arm 10 is in either extreme of its angular position, as in that holding the movable section drawn forward illustrated in Fig. 1, said arm will be resting against the stud at that side, and that end of the pedal or lever 16 at such side will be on the level with the frame-member 2 and resting in a socket or hook 22. When one end of the lever 16 is thus in one socket or hook,

22, the other end will be elevated, as shown in Fig. 1, and by pressing the foot forcibly upon the foot-piece or treadlc 17 thus elevated, the stud 21 in contact with the arm 10 will cause the latter to be raised up to and then past a vertical position, carrying the movable bed-section with it, until the latter descends by its own gravity onto the stationary section. During this latter action, the arm will move into contact with the other stud 21 and so swing down with it the formerly elevated treadle 17 into its socket or hook Q2.

For counterbalancing the movable bed section, the spring shown in Fig. 5 is provided, the central coil 23 of which encircles the rock shaft 14-, while its ends 24 press to. ward the abutment 25 having opposite notches 26, as illustrated in Figs. 3 and \Vhen the arms 10 swing past the vertical, the brace bar 15 comes against one of the terminal sections of said spring and carries the same along resistance thereof, thereby effecting two very important results, one bcing to cushion the descent of the arms 9, 10 and the movable bed section, and the other being to render their elevation easier. As the bar 15 swings over, it permits the depressed spring-terminal to return to its abutment-notch 2G, and then the bar takes the other springterminal from its abutment-notch and carries it along.

Another important function which is performed by this construction is that of locking the movable bed-section down in each of its lowermost positions. To accomplish this, I provide the strip of spring metal 27 having holes at its ends through which pass the said studs 21, and located between the arm 10 and the lever 16. Near each stud, is a corrugation 29 the crest of which is adapted to permit the arm 10 to forcibly pass it and then to lock the latter in its position against such stud, as indicated in Figs. 3.and at. baid spring strip 27 is preferably slightly with it against the springmovable bed section into its lowermost positions, said spring strips being adapted to .absorb a considerable proportion of the shock of such descent, by the resistance to the arm 10 given by the corrugation which it meets. Without such shock-absorber, the inovablebed-sectfion would land upon the floor with a heavy pound, for after the lever arm 16 has moved the arms 9, 10 well past of the grip their vertical positions, gravitation or momentum or both carries the bed-sectionthe rest of theway over and down to the floor. .After a quick pressure upon a treadle 17 has impelled the movable bed section Well past its intermediate position, its own gravity and momentum drive it onward and out I of the corrugation 29 confining its arm 10. I n Although I have shown and described this device as applied to a couch bed Whereinthe movable bed section is made to maintain a parallel motion, yet it will. work substantially as well with a couch bed in which the arms 9 are omitted, and the said section issupported at its outer side by its legs 5, and the casters 30 roll back and forth upon the floor; the inner side of the movable section being supported upon the arms 10.

Without the sockets or hooks 22, the depressed end of'the treadle arm 16 would be carried'to the floor, and so interfere with the rolling of the couch bed about the-room.

What I claim as myinvention and'for which I desire Letters Patent is as follows, to wit; Q 1. A couch bed comprising a stationary section, a'movable' section, a rocking frame carried by the stationary section and supporting the movable section, a treadle lever pivotallysupported at its mid-length torock concentric with and relative, to said frame, fixed stops for limiting thedegree of movement of said lever, means for limiting the extent to an angle materially less than that subtended by the rocking frame of said le- "vers movement relative to said frame, and a yielding buffer carried 'by said lever for absorbing the shock of the movable sections termination of movement whereby the swing of said lever is considerably less than that of said frame whereby the operative length of each section of the treadle lever is made long enough to give ample purchase for 2. A couch bed comprisinga stationary 1 section, a movable section, a rock-shaft supported by the stationary section, arm's fixed to said shaft and pivoted at their free ends to a side of the movable section, a treadle lever loosely mounted at its-mid-length upon said shaft close beside one of said arms, a, I

plate loosely mountedon said shaft close beside the said arm, and studs rigidly connect ing said plate and lever, said studs being far enough apart to permit a limited play of said arm between them.

3. A couch bed comprising a stationary section, a movable section, a rock shaft supported by the stationary section, arms fixed on said shaft and connected with the movable section, a treadle leverloosely mounted at its mid-lengthupon, said shaft close beside one of said arms, a plate loosely mounted on said shaft close beside the last-mentioned arm and opposite to said lever, studs rigidly connecting said plate and lever at'a distance each side said arm, stops for limiting the movements of said lever, and a shock ported by the stationary sect-ion, arms'fixed I on said shaft and connected with said movable section, a treadle lever loosely mounted at its mid-length on said shaft close beside I one of said arms, a plate loosely mounted on said shaft close beside the. last-mentioned 9' 5.

arm and opposite to said lever, studs rigidly connecting said plate and lever at a distance 'each side said arm, stops for limiting the movements of said lever, and a resilient plate having openingsv loosely fitting :said studs and corrugations adapted to act as shock absorbers for the last mentioned arm.

including a shaft supported by the station-10 5 ary section and connected" with the movable section, anda spring for partially supporting the movable section, said spring consisting of a length of resilient wire-rod bent at its mid-length into a coil encircling said shaft the stationary section being provided with a stop above said shaft adapted to be engaged by the terminal sections of said spring, said swinging frame having a member adapted "to engage said terminal sections one at a time. a

In testimony that I claim the foregoing invention, I have hereunto set my-hand this 4th day of December,'1911.
