Vfollowing a i'ull7 clear, concise, and exact description. rellznane being; had 'io the nc coinpanyme; drawing'. 'toi-innig a, part ol: this specihcation.

My intention relates to iniprovcinents in folding beds and has l'or .its object the prol duction of n. device in which the parts may be locked together under tension in closed position and unlocked and partly opened automatically from the frontor rear.

A further object is the production of iniproved locking and unlocking;r means.

A further object is theproifluction el? ihr proved ineens for holding the parts under tension either in .locked or unlocked position.

A further object is the production o'I` inn proved Ineens .for .Comici-ting the foot scction.

A further object is the production of` a device ofsiinplc yet efficient character, one that can be cheaply nninufactured and not liable to get ont of order.

These and such other objects as may hereinafter appear are attained by my device, an embodiment of which is shown in the accompanying drawing,- in which- Figure l shows my device partly in elevaA tion and partly in section with the parts unfolded and in the positionto be used as a. bed; Fig. 2 is a detail View of the locking mechanism; Fig. 3 representsa View on the line 3-3 of Fig. 2 looking in the direction indicated by the arrows; Fig. Ll represents topplan view of Fig. l partly` in section. Fig. 5 represents a View partl 1n elevation and partly in section showing my device in folded position. Fig. (5 represents a detail View in elevation showing a supportingr leg. view on the line 7-7 of Fig. 5 looking,r 1n the direction indicated by thearrovs; Fig.

Likenurnerals indicate like parts in the several figures of the drawings.

10 represents a side of the frame having Fig, 7 represents a detail sectional` nprights lil arranged at the rear thereof and arranged between thcsides l() and nprigrhs l1 is a frame constructed preferably ot' metal l'iaving' the sides l2 and front and rear conniaztinef bars 12S-1l These bars arc preferably o1" angle iron construction. i'iecured to the nprin'hts ll are brackets 15 lowing; slotted seats lli that receive headed pins or lugs if? on the cross-har l-l?. .le pivotcd latch is connected with the bar lll: and is ol sucl a length that when the pin 17 rests in the scat 1G of the bracket l5 the extremity of the latch 18 will engage the face of the upright 11,so thatby forcingthe latch i'lownwardly from the position shown in Fig'. 7 the extremity of the latch will bite into the t'acc of the upright 1l forming n wedge securing;r the parts firmly together.

Bracebars 19 extend across the frame formed by

thc'bars

12, 13, 1.4 and diagonally tlm-col? to reinforce the frame and supported by the frame thus formed are uprights 2O positioned, adjacent. the 'front of'the casing and adjacent opposite sides thereof. The scat or mattress supporting structure is formed of a series of

sections

21, 22, 23, 24. The sections and the sections Q3 are arranged end to end and the adjacent ends are pivotally connected as at 25 to the up rights 20. The section 21 is pivotally connected by one end as at QGwith the free end of the section Z2 and the sections 21 and E22 always remain within the casing.` The section 23 is adapted to be folded in and out of the casina and when unfolded projects beyond the front of the casing while the secm tion' 24 is pirotally connected adjacent one end 'with the free extremity of the section 255. A cross-bar 28 connects the free ends of the section 2i while the cross bar 29,con-` nects the free end of the section 21. Any nun'iber of cross bars may be provided in the :frame thus lformed and the elastic fabric 30 forming the support for thel mattress is secured to and foldable with this frame. A bracket 31 is connected with the section 22, see Fig. 1, and a guide link 32 is pivotally connected by one extremity with the bracket 31 and by its other extremity with the bar 12 and forms a support for the free end of the seection 21.

When the frame is olded, the section 24 turns about the pivot 217 and tlle-section 23 turns about the pivot 25 while the' section 21 is lcw'cred turning about the pivot 26, the section Q2 will turn about the pivot 25 and will drop' into the casing, the

sections

23 and 24 folding into the casing as shown in Fig. 5. The seat 322 is connected bv links 3d with the section to be suspended therefrom when the parts areuntolded, see Fig. 1, and stop pins vare provided i n the seat frame and with which fthe links 3 engage, thus limiting the backward movement of the seat.

The pillow rests 36 are pivoted at one end as at 37 to the'section 2l oi' the folding frame while theA other end of 'the pillow rests are pivoted as at 38 to a bracket 39 secured to the upright 20. An elastic member l0 is connected to an upright Lll secured to the bar 12 and also to a link #l2 which'is pivoted as at 43 to the pillow rest and a stoppin 44 is provided for the link to rest against. l'i/'hen the sections are unfolded as in Fig. l the spring l0 is under tension and assists'in folding the sections and when the sections are folded into the position shown in Fig. 5 the'spring 10 is also under tension i so that when the seat is unlocked the tension of the spring operates to raise the inner end of the seat suiliciently to permit the operator to grasp and unfold the sections.

The legs l5 are pivoted to the end. of the seat 33 and are ladapted to engage a bracket or stop 47 whilev a spring 48 is provided which tends to more the leg into the position shown in Fig. 6 and to cause it to as-l sume a position to support the seat when the sections 'are open. During the folding movement of the sections chains 49 which are secured to the cross bar 28 and also to the legs operate to pull-the legs in the folded position and when the sections are folded the cross bar 29 assumes a position to rest upon the cross braces 19 and thereby forms a support for the end of the seat which is adjacent the back.'

The seat and sections are locked in their folded position by a catch 50 pivoted as at 51 to a bracket 52 secured to the back 53 and the catch has a lip 54 which engages over a projection 55 on'the seat when the seat is folded. A. spring 56 tends to ,move the catch in a position to engage the shoul der 55 and tocause the lip 54 to stand in the path of the folding movement of the projec tion ,but will yield tolet the projection pass and then spring into lockingl position, This catch 50 is ltripped to unlock the seat either from the front or .from behind the back. lt is operated .from the front by means of a rod 57 having a pedal and a crank portion 59. The crank portion is located in line with the catch 50 and is con nected with the catch by means of chain so that when the pedal 58 is moved by thc foot in the direction of the arrow in Fig. 9 the chain 60 will pull the catch 50 aga-inst the tension of the spring 56 to move the lip 54 olf` of the catch of the projection 55 to unlock the seat, at which time the tension lalanne of the spring 40 willslightly raise the end ofthe seat. The catch is also operated from behind the back by means oi a rod 6l which is connected to one end of a lever 62, the

latter being-pivoted intermediate its ends as at 63, and a chain 64 is' connected to the other end of the lever and to a spring 65 at the top and behind the back. By pressn ing on the spring 65 the lever 62 willv be rocked and the bar 61 Will move the catch and release the seat.

lt will thus be seen that l have produced I a very e'licient locking means for holding the members in closed position, in combina.n x

Une of the great, disadvantages in (levices of this character heretofore has been that while it is absolutely necessary to grasp the seat in order to lift it, it is also essenp tial that the seat and back. fit closely nte gether, these two lrequirements conflicting one with the other it becomes a rather Chilicult matter to take care of these matters in a single structure. As an alternative, a piece of folded tape is often fastened to the end of the seat and it is permitted to project up between the seat and the back 'in such a. position that it may operator and used in opening the bed. This is all done away. with by my device, which insures both a ready opening and tight clo.

sure between the seat and the back. lit the be grasped by the' operator happens to be behind the structure y at the time he desires to open it, it is simply necessary to put his hand on the top of the member 11 reaching the ingers back under and around the spring member 65 when a slight pressure of the fingers will release lthe springand cause the seat to iy upward.

ln the improved leg` or support for the Toot oiE the bed section, l have provided a very eliicient mechanism that will drop into place for" supporting the bed when the tension on the chain ali) is removed, thus makin it always ready foruse, and will at the same time, when closed, be pulled into hori.

zontal position parallel with the seat andl held in' that position when' the bed is' ini i rlosed position as shown in Fig. 5. V/

.f'inothcr important' feature vin this construction is the' supporting plate 31 'by means of which the head support 32 /may be connected with the member 21 at a con- :anemie sid/arable distance above the plane of the member, thus making it possible, when the parte are folded into closed posltlon as shown `in 5 to permit thc mern'ber 21 to fall nearly horizontally and occupy a position close to the bottom of the structure, while the supporting member 32 remains at an angle to the member 2l, thus making i1t easy to lrlt the parts Without undue strain, and at the saine time leave a large open space 'under the sent for the storage of the mattress and clothes. The construction illustrated in Fig. l showing the extension member 24 is also a valuable feature in that it permits the 'forming' of a full Iwidth bed Without in any way distiiirbing the back. ,i

Heretofore in the opening of full width beds it has been necessary to turn up the back to get it out of the way in order to bring out the parts into unt'olded position. lin this coustructioii, however, by havingl the shorter supplemental member 2li pivoted on the section 22S at 27 and to the pillow rest at 3i' it is seen that a structure is provided that will autonilatically be forced downwardly as shown in Fig. 5 when the bed is oldcchthus bringing it entirely out of the way, concealing it within the frame and still leaving snl'licient mattress and clothes space underneath the scat. Vhen the seat is kicked up it. arises to an angle ot something' in the neighborhood ot' 30 to 45" from the .horizontal before the position of the member letis materially changed., Then as the bed is :further opened, the movement et the member 2li on the two pivots 27, Il?, riwings it about clear ot the bottom ot the back; so also in closing the bed, the reverse operationswings the member 2li about so that it clears the bottom of the back section which is rigidly secured in place.

(lli course, it clearly evident that many oit' the details et construction shown in cmbodiincn ts ot' my device illustrated may be changed or others substituted therefor, without departing 'from the spirit ol my i n volition.
