'Refiled for abandoned application Serial No. $1,07 July 17, I936. This application April '25, 1938,, Seria'lNo. 204,1 5fl 1 Claim.

"The present invention has as its principal .aim the provision of a spring structure for use with beds, although :certain "features of the invention may -be found'to be desirable in other cases Where mattresses or cushions or padding are to *be used upon the spring, ,so that while .ior the sake of brevity the title of the invention is .given as Bed structure it is intended that such Ttitle "be 'all 'comprehensive .as it were .so as to include "the adaptabifity of the invention to other Ebases than is furnished byla bedstead, cot or the .like.

In connection with beds'teads which ordinarily includes side rails and .ends attached to the side rails, preferably detachably, theinvention from I a broad point of view provides a mattress for cushioning receiving topsupported'by airamehf suitable construction, and movable elements .supported from opposite sides of the .frame, each :of which elements is adjustable independently of the other such e1ements,.and whioh may beaigidly fixed in'their adjusted position relatively to such frame, therebyprovidingmovableelements which may be brought into contact or hearing relation at preferably four points with the lateral sunfaces of the base or bedstead which is adapted .to support the frame, whereby :sueh .irame may be centralized or oriented symmetrically respect to the base .or bedstead to prevent :lateral shifting of the frame relatively to the lease.

"Such a .centralizable .spring \or the :like is new in the art, .as the make-shift devices-of the prior art, while adapted to support such a spring aor thelike-from a'base, do not in association there- -with serve to centralize the spring i! the like with respect to the base, that is, do not-so :support the spring-or the like that the latter stays put, inasmuch as Jay the use of the present inmention any .lateral shifting -.of the .frame :relatively to the :base is prevented; that is, :it maybe prevented whenever desired .it the spring is tin the first instance adjusted to the desired definite ,position.

The improvements of the present invention adapt the spring structure for a more or less universal adjustment and zcentralizin'g thereof, that :is a given size of spring structure, with tiespect to "bases and more particularly bed-stea'ds which are of different types -=of construction, no achange :in such construction being necessitated when the universally adjustable spring of "the present invention is used. In connection with beds it is stated that :the United states .Depart- :ment of Commerce has issued isdhedules ireo'ommending-standard sizes for oneta'lzandwood beds,

indicating *the different dimensions -*of such beds to accommodate :coil springs and link springs of given "dimensions of such springs, showing "that inoonnectio'n with link springs, tor example, diverse dimensions thereof are recommended ior meted beds and wood beds "of relatively diiierent and this practice when followed would mean that each link spring of given di- 'mensionswouldhave to be diffieren'tly constructed and proportioned to go onto metal and wood "beds of diii erent dimensions adapted to receive such iink isprings of given dimensions.

[tinder the present invention "the principal *aim *is to so construct a link spring that it may 'be "fitted to meta-1 beds and wood beds of diii'erent dimensions -without having to change the construction of the link spring whereby the latter is so a dented.

"These being among the objects (if the present invent-ion, the same consists of certain "features of construction and combinations of parts to be hereinafter described and then *claimedwith referenee "to theaccompanying drawings illustrating V apre'ferred embodiment of the'invention ap- :p'lied, but not necessarily, to metal and wood beds, and wherein Fig. "l is a plan .s'howing a link sprin Provided "with the :present improvements, and which "is shown as broken transversely through the bedstead and fbrdkenlongitudinalhr through the bedstead, parts being omitted .for the .sake of clear- ,ness; Fig.2 is a longitudinal section on the :line 2-4, .Fig. .1, showing one of the side rails of ;a bedstead broken away, and parts being in elevation;

'3 is a -vertiea1 section :on the line 3-3, .l lig. 12, showing two side rails, :the wiew being woken away :mfits middle portion;

Fig. :4 .is :a elevation showing the same parts as shown to the lleft of Eig. B, but il-lustra'ting the improvements :as applied to "metal Ebedsteads :haning side -ra'ils of angle metal with ,45 the horizontal flange of reach Iecatedat the bot- '55 ef the adjustable elements 'or members "slidably connect the parts together in well known man-.

ner. In these figures of the drawings the angle metal rails l9, H are shown with their horizontal flanges extending inwardlyfrom the up-,

per edges of the vertical flanges, so that the corner of the angle metal is at the top of the rail. 7 The illustrated bed bottom or spring provided with the present improvements includes cross pieces IS, IS at the opposite ends and which are preferably formed of angle metal, each with a horizontal flange and a vertical flange 3, these cross pieces I5, 16 being parallel with each other and the horizontal flanges I1 being directed inwardly towards each other. A pair of preferably cast metal brackets I9 is fixed one at each end of the cross piece l and a similar pair of brackets 29 is fixed, one to each end, of the crosspiece I6, although the drawings illustrate but one of the brackets 20. It will be readilyunderstood that the bracket which is omitted from the upper right hand corner of Fig. l-will correspond to that one of the brackets l9 which is located longitudinally away from it on the spring frame, such omitted bracket 20 in other words corresponding to that meet the pair of brackets 2 19 shown in Fig. 3which is located to the left of Fig.3. v A

The brackets I9, 29 preferably extend downwardly from the cross-pieces l5, l6 and their lower ends are disposed inwardly with respect to the vertical planes of the flanges l8 which is preferably accomplished by curving the brackets I9, 20 -in opposite directions outwardly. away from their lower ends. In order to secure each bracket to its proper cross piece, the upper end 'of each is provided with a mounting plate 2| which is placed against the inner surface of the appropriate flange l8, and then each plate is preferably rivetedtosuch flange, preferably two rivets being employed so as to rigidly retain each bracket 19,20 ina plane'to extend at right angles to the plane of the upper flanges of the cross pieces l5, I6. At the lower end of each bracket !9 and: 20- there is formed a socket 22, and the socketsofthe respective brackets'l9, 20 receive the ends of metal side bars 23, which are rigidly securedtherein as by a friction fit or otherwise, as desired. Theparallel side bars 23 may each be formed witha metal tube of cylindrical shape, for the sake of lightness, although the cross-sections of the side bars and of the sockets 22 need not be cylindrical These side bars 23, the brackets I9,,2EI and the cross-pieces I5, I6 .thuspreferablyconstitute a rigid frame.

- As the illustrated, frame I 5, l6, etc., is con- Y structed to adapt: it for supporting link springs, there is illustrated aywire-link fabric top 24 (Fig. 1) which may be of any suitable construction and connected at opposite ends thereof, by means of helical tension springs 23, with the horizontal flanges I! of the cross-pieces, such flanges being perforated in the usual manner to receivehooks at the'ends of the tension springs 25;;Th'us'th top24is made flexible and resilient so as to constitute a supporting spring for a mattress or the like.

At the outer ends of the sockets 22 they are closed by abutments or seats 26, preferably formed integrally with the brackets and which are arranged in parallel vertical planes. Parallel shoulders 21, 28 are formed on each bracket to extend beyond the abutment or seat 26, these shoulders extending horizontally in the direction of the width of the frame l5, l6, etc. Each pair of shoulders 21, 28 provides a guide-way between them, and if desired the shoulders and the guideway may be differently constructed for accomplishing the ultimate end in view. There will hence be four pairs of shoulders corresponding with the four brackets in the preferable construction, and between the shoulders of each pair their is mounted a movable elongated metallic member 29, as shown in perspective in Fig. '7.

. Each movable member 29 is preferably of plate 'form'or type and the plate portion 30 is preferably setonedge to stand vertically between the shouldersZ'l, 28 of each pair of shoulders, and

there will hence preferably be four of the metallic members 29. Preferably the thickness of each plate portion 30 corresponds to the depth of the groove formed between the shoulders 21, 28 so that its outer surface is flush with the corresponding surfaces of the shoulders. These metallic members 29 should be strong and durable as they are adapted to constitute the supports for the frame l5, l6, etc., upon a supporting base or bedstead. Also to this and preferably each of the plates 39 is provided .with a reinforcing edge portion 3| which gradually tapers'from the lower edge of the plate portion 30 in a curve was to merge with the upper edge of the plate portion. That is, the upper edge of the plate portion and its outer end are reinforced and strengthened by an edge portion. 3| which gradually enlarges in width from the. top of the plate portion, and where it passes the lower edgeof' the plate portion it forms a downwardly-projectingtoe 32, that is, a toe which" is located at the outer end of each movable member 29 and'which preferably projects at right angles thereto.

Each of the preferably four movable members 29 is-provided with a longitudinal slot 33 of ,suitablelengthpreferably atleast one and three 'quarters inches, so that a set-screw with a head 34 and a screw stem 35 may be engaged with the movable member, the screw stem 35 being screwed into a screw threaded hole at the center of the abutment or seat 26. It will therefore be seen that each movable member 29 may be moved outwardly or inwardly to adjust its toe 32 to' a desired position, and when the setscrews are tightened up, the head 34 of each will be brought to bear firmly upon the outer surface of the corresponding movable member 29, thereby releasably securing the 'movable member 29 positively in a predetermined position.'. 1

Accordingto the present disclosure there will therefore beat least four movable members 29,

one of each being located at a corresponding corher of the frame l5, [6, etc., or more specifically there will be-apair of the movable members 29 at each end of; theframe l5, it, etc., which extend outwardly, sothat there is a pair adjacent to and parallel with the cross-piece l5 and another pair jofthe members 29 adjacent to and parallel; with the cross-piece l6;"as shown more clearly in Fig. .1. clear therefore the :movable members. 29 as adjusted in zone 'horizcntal :plane which is parallel with and :be-

-or bedstead are required for a removable f-rame .for'the differentlycons'tructed hases 'or' beds'teads.

The drawings tilluslmate the bottom frame or .iSpJfiTlg :as :applied bedsteads :of four different constructions, .and it :is to the understood that if the invention is :to be adapted .to Eba'ses or ibed- .steads :of dimensions from the .ones to which a given :size of removable frame or spring may be applied, it will still be applicable Tunive'rsally tootherrdilfeiient sizes to receive a given size of removable frame or spring. In Figs. 1, 2 and 3 the removable frame or spring has been shown as applied to and centered with respect to a base or bedstead having side rails whereof the horizontal flanges extend inwardly from the upper edges of the vertical flanges. In such case the movable members 29 are adjusted outwardly a slight distance from the brackets supporting them so that the outer ends of the slots 33 will be located somewhat in advance of the set- screws 34, 35, and the toes 32 of the movable members 29 will be engaged over the outer surfaces of the rails II], II, at points opposite to the horizontal flanges of said rails. When the parts have been so adjusted and the screws or fastenings 34, 35 set to lock or secure the movable members 29 in their adjusted position, the engagement of the inner surfaces of the toes 32 with the outer surfaces of the rails II], II will positively act to prevent any lateral shifting of the removable frame or spring with respect to the base on which it is supported, inasmuch as preferably there are four points of contact with said rails, two points of contact at each side of the bed or other base, and thereby the removable frame or spring is held centralized with respect to the supporting base, as it cannot be shifted laterally thereof at either end, without first loosening the fastenings or setscrews 34, 35. Therefore, by utilizing the present invention each side of the removable spring structure is prevented from moving inwardly away from a side rail as it is not supported in such manner as to allow the spring to fall at that side, and furthermore the spring structure is prevented from being twisted laterally of itself in such way as to demount one of the movable members 29 from the side rail or the like on which it is supported.

In Fig. 4 of the drawings the sameremovable frame or spring construction as described with respect to Figs. 1, 2 and 3 is shown as supported by the horizontal flanges of side rails, such as rail 36, wherein the horizontal flange extends inwardly of the rail beyond the lower edge of its vertical flange. In such an installation, the removable frame or springstructure is set at a lower level than in Figs. 1, 2 and 3, because the toes 32 or the ends of the movable elements 29 are in contact with the inner surfaces of vertical flanges of rails such as 36, and the lower ends of the toes would be resting upon the horizontal flanges of such rails, thereby supporting the frame or spring structure, while at the same time the latter is centralized with respect to the side rails. Inasmuch as the thickness of the metal side rails of bedsteads is usually :a quarter of an inch, the adlustment of each 201' the movable members in Fig. 3 is approximately a quarter of an inch further erentls of the slots 33 would be --direct abutment with the set-screws or fastenings, .as the removable elements are here shown adjusted inwardly to innermost :limit.

In Fig. 5 the improved removable frame or spring structure is ras installed on :a "bedistead whereof each ofithe sider'ails fill wood.

Asimade by different rmannfaetucws the thickness of each wooden side rail may vary, rout as the dimension -between "the outer surface of the side rails even in such :cases usually remains the same, with each wood side mail at least alnfinch in thickness, the movable elements 9 are shown as adjusted outwardly te their utmost limits. this case the .springgstructure would be supported by the movable members 2i9 while the inner surfaces of the toes 32 will be in bearing contact with the outer surfaces of such rails as 31, at the up- .per portions of the rails. In this instance the removable spring structure would be centralized with respect to the wood bed structure in the same manner as in Figs. 1, 2 and 3, except that the toes engage wood side rails instead of metal side rails.

In Fig. 6 the removable frame or spring structure is shown as installed on a bedstead with wood side rails, such as rail 38, between which rail and the corresponding rail, not shown, transverse slats 39 of old fashion are employed. In this instance the removable frame or spring structure is supported upon the slats, such as 39, which are behind the slat 39 which is shown, by resting the side bars 23 of the frame upon the outer ends of such slats, while the toes 32 would be located between adjacent slats, but the outer surfaces of the toes or the outer ends of the movable members 29 would be in contact with the inner surfaces of the wood side rails, such as rail 38. In this way the removable frame or spring structure is vertically supported upon the slats without using the movable members 29 as supports, the outer ends of the latter contacting with the innor surface of the side rails so as to centralize and orient the removable frame properly with respect to the bedstead. Hence the movable members 29 may either constitute supports for the removable frame or spring structure or they may merely, constitute movable elements or members which contact with lateral surfaces of the bedstead or other base. In Fig. 6 the movable elements 29 are adjusted to intermediate positions, that is to say, each set-screw passes through the slot 33 near the midlength thereof.

From the description and drawings herein it is apparent that in Figs. 3 and 5 the laterally contacting parts such as the depending toes 32 engage with the outer lateral surfaces of the supporting base, thus illustrating two ways in which the invention may be utilized, and if it was not for the fact that it is preferable to use the movable members for obtaining a centralizing of the spring structure in at least two more ways such as shown in Figs. 4 and 6, the depending toes 32 might be omitted, inasmuch as in the two figures last mentioned it is really the outer ends of the movable members of elements which provide the lateral contact.

It will be readily understood by those skilled in this art that the invention as illustrated and described is susceptible of more or less modification without departing from the scope of the appended claim, and it is to be clearly'understood that used in other connections, and such introductory clause is intended to be all comprehensive as it were, and is not used as a limitation, except where required by the substance or essential features of a claim.

The present application is a refile for application Serial No; 91,071, filed July 17, 1936, which application became abandoned March 3, 1937.

What I claim as new is:

In a rectangular spring construction, an adjustable support connection to support said rectangular spring construction upon the side rails of metal and wood bed frames, said side rails being of rectangular and right angular cross sections, said rectangular spring construction including a rectangular frame, and also including downwardly extending brackets, said connection comprising a seat formed in the side of the lower end of one of said brackets, a slotted sliding bar fitting in said seat, the axis of said bar being hori zontally disposed and being transverse to the axes of the side rails and the plane of said bar being vertical, and a bolt extending through said slot and fixed in said seat to fix said bar in an adjusted position, said seat having upper and lower guiding projections closely fitting the upper and lower edges of said bar and said bar having a downwardly projecting lip extending transversely across the outer end of said bar, said lip fitting on the corner or over the corner of said rails of right angular cross section and fitting over the corner of side rails of rectangular cross section, the upper edge of said bar being widened and turned downwardly adjacent its outer end to form said lip.
