SPECIFICATION forming part of Letters Patent No. 695,607, dated March 18, 1902. Application inea November s, 1900. serial No. 35,792. v LND man.)

To all whom it may concern:

.Be it known that I,`ALii"fuiD` GUAY, a subject of Her Majesty the Queen of Great Britain, residing at 4'Maxville, in the county of l 5 Glengarry,'Province of Ontario, Canada,have

invented certain newl and useful Improvel ments in Bed-Springs; and I do hereby de- "claro that the following is `a full, clear,.and i exact description of the invention, such as to: willenable others skilled in the art to which lit appertains to makeand use'the same:

'My invention relates to improvements in jgbed-springs; `and the primary object that I havein View is to provide means for securely r5`connecting the side and cross rails to the r spring-frame in a manner to. hold the parts in Y. Operativerelation and at the same time make -provision for adjustment of the cross-rails relative to the s ide rails, so as to eect an increase ordecrease in the width of the availj ahle surface forming the bed-bottom.

yA-iiurtherobject of the invention is to imy'prove the construction of the bed-spring in a way-to reduce the elasticity and sagging of the active surface while retaining a certain 'tamount of elasticity which will secure the necessary comfort to the'occupant of the bed.

Eilrther objectsand advantages of the invention will appear in the course of the sub- 39 joined description, and theI novelty in the s combination of devices and in the construction and arrangementof parts will be defined by the claims. s 1

.1 In theA accompanying drawings, forming al .35 part of this specification, Figure 1 is a plan y, view of a bed-spring embodying my improvements and showingthe parts adj usted Within the smallest limit to )it a narrow bedstead. Fig. 2 is a plan View similar to Fig. 1 and showing the bed-spring adjusted to fit wide i .f 2.' Fig. 4. is a sectional view through the side -rail and a portion of a cross-rail to show the meansfor adjusting the latter with respect f to .the side rail, the plane'of the section being indicated by the dotted line 14 on Fig.1.- Eig. 5 is an enlarged sectional elevation in the plane of the dotted line 5 5 on Eig. 2 and "5e 'taken longitudin:.lly through a portion of the side rail andtransversely through across-rail. .6 is. a .detail perspective of one of the corner-irons employed to imite the side and cross rails adj ustably together. Fig. f7 is an enlarged fragmentary View of a portion Yof the bed-bottom. i

Thel same numerals of reference denote like parts in each of the several figures the drawings. 1

The frame of the bedspring consists of the side rails 10 11 and the crossfrails 1'2 .13.. These rails are arranged for the end portions of the cross-rails to overlap the corresponding portions of 'the side rails, as represented', more vclearly by Figs. 3 to 5,V inclusive, and ithese rails are united firmly and adj ustablytogether at their meeting ends by employing a` series of corner-irons 15. One corner-iront` is fas- -tened to a side rail at each end thereof and arranged in a position to receive an end portion of a cross-rail, all of said parts being joined together in a manner to permitthe cross-rail and the corner-iron to be adjnsted simultaneously for a limited distance in the direction of the length of the side rail, vso asto stretch the bed-bottom longitudinally, while at the same time each side railv is capable of v a limited lateral adjustment in the direction of the length of the' cross-rail, such last-'described adjustment being for the purpose of shifting the two side rails laterally and independently with respect to the bed-bottom,and

thereby enable one or twosupplemental bedbottom sections to be brought into position for use and effect an increase in the width of the bed-frame, as will hereinafter more fully appear.

Each corner-iron is cast in a single piece of metal in the form shown more clearly by Fig. 6 I

of the drawings, and said corner-iron consists of a base-plate 16, a back plate 17 ,'an overlap?4 ping flange 18, and a front' flange 19, all of which are castin asingle piece of metal. The back plaie 17 rises vertically from 'one edge of the base-plate, and from the top edge of said base-plate projects the overhanging flange 18, the latter being furthermore provided with the lugs 20, from Which-rise the studs 21. The

frontl iiange 19 extends upwardly from the .front edge of the base-plate 16, soas to lie par- 'allel with the back plate 17 ,and thereby give to the corner-iron the appearance of aboxing in.

cross-section, as represented more clearly by Fig. 5, whereby the cornerLiron is adapted tov IOO ' embrace the cross-rail on allot its sides. The

corner is furthermore provided at one end of the front flange with an opstanding bearinglug 22, the latter having in one face thereof a cavity 23, adapted to receive one end of an adjustingscrew-spindle24. Thespindle finds a threaded bearing in a bracket 25, which is secured by any approved means to one side rail at a poliptadjacent to the,cross-ral, said bracket Vbeing arranged on the side rail in a manner to support the screw-spindle 24 in such a position that its longitudinal axis will lie parallel to the corresponding axis of the side rail, whereby the screw-spindle is mo'unted seas to el'eet the adjustment of the corner-iron in the direction of the length of the side rail. (See Fig. 5.) This corner-iron is furthermore provided with a longitudinal dovetailed rib 26, and said rib and the baseplate of said iron have the longitudinal slot 27 formed therein. The base-plate of the corner-iron or the dovetailed rib 26 thereon is pierced bya bolt-hole 28,th rough which passes a bolt 29, havingat its upper end a head which is countersunk in Athe bolt-hole, so Aas to lie ush with the rib. Said bolt passes through alongitudinal slot 30, which is formed in the side rail 10 or 11 near one end portion thereof,

whereby the bolt serves to attach the corneriron 15 to the slotted portion of the side rail in' a manner for said corner-iron to be adjusted a limited distance on the rotation of the screwspindle. This adjustment of the two cornerirons connected to the opposite c nd portions of the cross-rail 12 provides means by which said corner-irons and the cross-rail may be shifted lengthwise on the side rails 10 11, and thus the bed-bottom may be stretched longitudinally, so as to take u p undesirable slack and restore the bedbottom to a taut condition.

Each cross-rail 12 or 13 is provided in the under side of each end portion thereof/with a dovetailed groove 3l, the latter arranged to receive the dovetailed rib 26 on the baseplate of one corner-iron, whereby the corneriron is adapted to have firm engagement with the cross-rail to hold the same in position against edgewise displacement under the strain of the bed-bottom. At the same time the dovetailed rib 26 is as long as the slet 27 to enable the side rail to be moved laterally with relation to the cross-rail and the bedbottom. VI will now proceed to describe one embodiment of means by which this lateral, adjustmentof the two side rails may be obtained independently with respect to the cross-rails and the bed-botto|n, reference being had more particularly to Figs. 4 and 6.

A vertical bolt32 lpasses through an opening ofthe cross-rail and through the slot 27 of the corner-iron, the lower ond ot said bolt having a nut Said bolt 32 passes through an eye 34, which is formed in the flattened and bent end 35 of an adj listing-screw 36, the latter being arranged in a horizontal position below the cross-rail and parallel therewith. The base-plate 16 ,of the corner-iron extends for a suitable distance inwardly from the side rail, and near its inner end said baseplate 16 is formed with the bearing-lug 37 and the lip 38, said lug 37 having a suitable openingr through which the adj listing-spindle 36 is loosely passed. The lip 38 is parallelwith the lug 37, so as to form an in ervening space in which is received a colla 39 of at son of the lip 38 fitting loosely in the groove 41 of the nut, and said nut has ,threaded engagement with thespindle 36 and it abuts against the lug 37,- the latter serving as a bearing for the nut when it is rotated for adjusting the spindle. It is to be understood that the bolts 32 `are fastened to each crossrail in a manner to connect the screws or spindles 36 with said cross-rail, whileL the bolts are free to movein the slots 27 of the corner-iron. By rotating the thumb-.nutof the adjusting devices associated with` one side rail the screws or spindles 36 may be actuated to move the bolts 32, and thereby shift the side rail laterally with respect to the cross-rail and the bed-bottom, each side rail being shit'table independently'of the other. This movement of the side rail at each sidel of the bed-frame operates to shift the position of `the rail relativeto the bed-bottom, and in this connection it is to be observed that the thumb nutsand screws provide ICO means by which the desired adjustments may f be easily secured. This shiftingofthe side rails independently or collectively serves to materially widen the frame of the bed-spring,

as represented by Fig. 2; but such adjust-4 ment allows vacant spacesto exist atene4 or both sides ofl thebed frame. 'Io fill up,`

IOS

said vacant space or spaces and to provide a practically-continuous spring-surface, I`

contemplate the 'employment of two auxiliary bedbottom sections arranged at oppe site side,edges of tbe spring-bed, as shown by Figs. 1, 2, and 3. The main portion or body of the bed-spring is represented in its entirety by the numeral 42, and the auxiliary .bed-bottom sections are indicated at 43 43.

Each auxiliary section consists of th'e longitudinal strands 44 44, the coiled springs 45, having the hooks46, and the weaving or filling wires 47. The coiled springs of each 'auxiliary section are attached to the ends of the longitudinal strands, so that the hooks 46 may engage with the studs 2l on two of `the corner-irons, andthe weaving or filling wires connect the strands 44 il, so as to make a complete section, the width of the latter be-- ing but a fragment of the width ot the spring betteln 42. are arranged to partially close the space be` tween'the strands, the latterbeiug bent upon themselves to form the eyes 51, and each lilling-wire crosses diagonally between two ldjacent strands, so that each iilling-wire may IIO .The filling-wires of eaclrsection 'ipass'thrdugh an eye on one strand, theny thenback' to another eye on the first strand,

across't'o'a similar eye 'on' an adjacent strand,

and s o on throughout the length of the section. When twofilling-wires are employed, they cross each other, becausethey are re- `vers'ely arranged. It is to be observed that eachauxiliarysection 43 or 43 has -its end l portions connected withthe studs on the overhanging lianges of two 'corner-irons, and thus each auxiliary section is made somewhat longer than the bed-bottomv42, and is also ar- 4 latter retain its shape when the parts are adjusted, so as to bring one or both of the anxiliary sections into positions for service as a partof the spring-bed, as shown by Fig. 2. Each auxiliary section is' intended to be applied totwo ofthe corner-irons 15 between the side rail and the two cross-rails, so

. that in thenarrow adjustment of the bedspring this auxiliary section '42 will lie over one: side edge of the bed-bottom 42. It is my practice' to make the bed-spring when adjusted as shown by Fig. 1 of such a width .ent widths.

asto fit a narrow bedstead, which is now ordinarily made three feetand eleven inches wide.

It is common at this date to make bedsteads which vary in width from three feet eleven inches up to four feet fonrinches, and we thus iind on the market diierent or various makes of bedsteads, so that there is a diffe1..

, ence of five inches between the narrowest and widest bedsteads. My construction provides for adjustment of the bed-frame to lit the widest as well as the narrowest bedsteads, and to fill up the space between one'or both side rails and the edge of the bed-bottom 42 when the bed-spring is adj ustedv to fit.the widest bedstead (four feet fourinches in width) I employ the two auxiliary sections 43 43a. :It is to be observed that these auxiliary sections remain attached to the bed-spring frame, so as to overlap the edges of the bottom 42, and they are thus alwaysin a position to occupy the unfilled spaces between the side rails and the bed-bottoms edges when the parts are adjusted more or less to iit bedsteadsof differ- I also contemplate a constructionof tle bed-bottom 42 which will overcome the undue sagging of the bottom after continued use as well as excessive elasticity in the structure of the bo'ttom. I employ a plurality of stout longitudinal wires 50, each having a series of loops or eyes/5l formed atv regular intervals therein. The coiled springs 52 53 are connected to opposite end portions of each looped strand 50, and each spring has a link 54 attached thereto, which link is se- 'cured to one of the cross-rails. The longitudinal strands are arranged parallel to each other at proper distances apart and so as to bring the loops or eyes 5l of one strand in a corresponding position to the eyes of an adjacent strand or strands. (See Fig. 7.) The spaces between the series ofl looped strands are partly occupied by av wire filling, which consists of the wires 55, lthat cross each other between two adjacent strands and are threadr ed through the loops o r eyes 51 of said strands.

i The bed-bottom of my invention has an effective surface formed by the strands, the

lilling-wires, and the springs which aords a proper support for a hair or other mattress.

The desired elasticity of the bed is attained by the provision of the springs between thel strands and the rail-'attaching links; but these springs are made quite stiff forthe purpose of overcoming undue sagging of the bot- Changes within the scope of the appended claims may be made in the form andproportionV of some of the parts, while their essential features are retained and the spirit of the invention is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.
