SOFA-BED.

To all lwhom, t may concern.' 4

Be it known that I, FREDERICK BENNETT, Long Island, city of New York, county of Queens, and State of New York, have invented certain new and useful Improvements in Sofa-Beds, -of which the following. is a full, clear, and exactspecification, such as will enable 'others skilled in the art to which it appertains to make andvuse the same.

This invention relates to that Atype of sofa bed in which there' are relatively movable members which, when in one position, form the seat and back of a sofa, and, when in another position, form two adjacent 'sec-l tions of a bed body.

In my improved construction, there is provided. an auxiliary member or section,

which, when the main members are in sofa position, serves to cover one of said 'main members, and when the main members are in bed position, the auxiliary section serves to cover the' other member.

yThemain object of my invention is to bring Aaboutthe automatic positioning of. this auxiliary section as the main members or sections are moved from'bed* position to sofa position, or vice versa. It ,is also an object of my invention to connect these members in such a way that a minimum number of parts shall be employed, theunemb'ers shall be positively interlocked when in normal positions, and the bed members shall be practically co-balancf ing in any and all intermediate positions, all lauxiliary retaining and positioning elements, such as springs, locks or the like, may be dispensed with. .These and other features of importance will be fully set forth hereinafter and particularly" pointed out in the claims.

Reference is now had to. the accompanyi'ng drawings, which represent as an exl' diate of the bed and-sofa ample one embodiment of my invention, in which drawings- Figure 1 is an end elevation of a portion of a sofa bed with the members shown in solid lilies in the sofa position,"and `in dotted lines in bed osition, the usual end arms being remove Fig. 2 is a similar view with the movable members inte-rmeposition, and Fig. 3 is an` end elevation of the 'sofa bed on a smaller scale, one of the arms being broken Patented Mar. 25, 1913.

soli J lines inv the sofa position.

My invention different lforms acter above referred to,fbut it is especially adaptedv to the sofa bed illustrated in my previous Patent No. 888,865, granted ,May

andthe members being shown in 26, 1908. `In 'the accompanying drawing, I

have illustrated my invention as .applied to the sofa bed shown insaidv patent and, therefore, I have not'illustrate-d in detail the construction of the body of the sofa bed. I have' merely shown the two main members, or sections 1 and 2,hinged together by butts 3 and 4 and a pin 5. The member 2 is movable so as to form either the back of a sofa or one section of a bed,`

and is connected by links 6 to the frame 7 of the bed. The member 1 is slidable within the frame, and may be mounted on suitable rol'lers'8. To this extent, the parts are substantially identical with those -illuslines in the bed position and in dotted may be applied to various of sofa beds of the chartrated in sald patent and operate in exactly the same manner.

-The main feature of my present invent-ion relates to an auxiliary cushion or mattress member-11, which covers the seat section when the 'parts are in sofa position, and

covers the back section when the latter is moved from sofa lposition to bed po-sit-ion. This auxiliary section ris so mounted that it automatically shifts from one position to the other'upon the movement of parts from sofa to bed `position o'r -vice versa. The specie mechanism for accomplishing this automtic movement involves merely a link 13 supported and controlled by suitable pivots or stops. The butt 3 has an upward extension 9 above the pivot 5, and this extension lis directly-secured to the auxiliary sectionl 11 by a pivot pin 10. .The butt 4 has an extension 16` projecting from the lower end ofthe section2 whenthe latter is in sofa position, and to this. extension is pivoted the link 13 by a-suitable pivotpin lf.- Thelink ,13 is fulcrumed on the pivot pin 5, and is pivoted to the section 11-by a. suitable pin 15. The link 13, therefore, has its ends pivoted to the main section '2 and the auxillary section 11, and is fulcrumed intermediate its ends upon the main section 1. To permit the parts to b e moved, the link 13 must move lengthwisein respect to when in use as a sofa,

one or more of theA pins 5, 15 and'17. It is' not material at which of these pins the slid- I '17 extend. This prevents the lever from extending upwardly above the section 11 when the latter is in either position.

The rotatable bedv member 2 may be of less thickness than the other member 1, so that when the device is used as a bed, the uppermost -surface of the auxiliary cushion 11 will lie in,the same plane as the upper surface of the normally non-rotatable bed member 1, thus o'ering a continuous b'ed mattress. lThis effect, however, maybe accomplished in any desired manner.

In operation any movement of one member is accomplished by a movement of the other two, and any one may be ymanually moved to move all three. For instance,

11 lies fiat on theseat member 1, 'and the back member is substantially vertical, as shown in Fig. 1. To convert` the sofa int-o a bed, the auxiliary cushion 11 is grasped `at its outer edge and raised. As the pivot 15 describes an arc, pressure is exerted on the stud 17 secured to the butt 4. of the back` the lower edge of, tlielatter.

member 2, and is brought forward until the back section is lowered to a horizontal position and rests on the rollers 8,- orl upon any other suitable support. This movement is controlled by the link 6. Simultaneously, the seat. member 1 slides forward with the lower end of the, back section. The auxiliary Acushion continues its rotation until `it lies -flat on the member 2, -as

best shown in Fig. 3. Throughout this movement the members approximately balance each other and are rei strained from unduly rapid reversals, by

reason of the continuously changing leverages of the connecting parts and the compensating effect produced: e t y I do not limit myself to the recise -link motion described, as all devicesor securing an automatic copositioning of three or more bed members are -within -the-scope of my invention.

the auxiliaryl cushion.

Having thus described my invention what I claim as new and desire to secure-byv Letters Patent, is:

1`. A sofa-bed main sections hinged together, a movable auxiliary section, ing one end pivoted to one of the main vsections, .and the other end to the auxiliary section, whereby said auxiliary section is adapted to automatically operate the main sect-ions.

2. A sofa-bed having in combination, hinged seat and back-sections, a movable auxiliary section, and slotted levers fulcrumed on the pintles connect-ing the hinged sections together, said levers having one end pivoted to the auxiliary section and the other end loo'sely connected to theback-section, whereby a movement of one ysection will impart motion to the other sections.

'3. A sofa-bed having in combination, seat and back sections hinged together, the back being movable to constitute a sofa back or bed section, an auxiliary section lpivoted adjacent to said hinged connections and movable to fold upon either the .seat-section or the back-section, and means whereby the auxiliary section may be automatically shifted upon a relative movement of s'aid seat and fulcrumed` levers hav- K or back-section and the seat 4and back section upon .a relative movement of the auxiliary section. A

4. A sofa-bed'having in combination, two sections hinged together, one of said sections being movably-mounted frames, an auxiliary section, and levers having one end pivoted to said auxiliary section andthe oppositev end loosely-connected to the movably-connected section, said levers being loosely fulcrumed on the pintles of the hinged connections, whereby the movement of either section will impart motion to the other sections.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
