BED-SPRING.

Specication of Letters Patent. i

Patented Dec. 8, 1914.

Application filed June 21, 1911. Serial No. 634,414.

To all whom t may conce-m Be it known that I, CHARLES IIULPIAN, a citizen of the United States, residing at BuHalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Bed-Springs, of which the following is a specification.

This invention relates to improvements in bed springs which are intended for use in iron and wooden beds and are adapted to be supported from the side or end rails thereof.

The object of this invention is to provide a bed spring of this kind with simple and inexpensive supporting means which aie adapted to engage the side or end rails of the bed and which can be easily adjusted to increase or diminish the width or length of the bed spring, so that the latter can be readily fitted to beds of different sizes and secured in place therein.

In the accompanying drawings: Figure l is a fragmentary plan view of a bed spring embodying the invention. Fig. 2 is a frag mentary perspective view thereof with the springs removed. Fig. 3 is a fragmentary end elevation thereof on an enlarged scale.

Like reference characters referto the like parts in the several figures.

The bed spring shown, in its general construction, is of usual type and comprises a supporting frame A composed of a plurality of transverse slats a which are connected together by cross bars a to form the frame, and a plurality of upright coiled springs B which rest upon and are secured at their lower ends to the transverse slats and are connected together at their upper ends by longitudinal and transversely eX- tending wires which retain them in their upright position. These parts may all be of any suitable constructionand arrangement.

The present invention relates only to the means which are employed for supporting the bed spring in position in the frame of the bed and which are constructed as follows: The supporting frame A is provided at its opposite side edges with supporting arms C which are pivoted thereto, so as to turn or swing in a plane substantially parallel with the plane of the frame. In frames where transverse slats are employed, as shown in the drawings, the arms C are preferably pivoted to the opposite ends of these slats. In these frames the slats are formed of angle iron and are arranged with their upper flanges extending in the plane of the frame A and the supporting which is pivotally secured thereto and eXf i tends parallel with the side of the frame.

The bar D is provided at intervals through-` i out its length with hooks Z which project outwardly therefrom and are adapted to engage the side rails of the bed for supporting the springs thereon.

In the drawings the supporting means at one side only of the frame A are shown, but.

it will be understood that similarly constructed supporting means are employed for the other or opposite side of the frame.

The connectingbar D causes the arms C at each side of the frame to turn in unison about their respective pivotal connections with the frame A and the construction is such that the arms can be swung inwardly toward the frame to a point where the hooks Z carried by these arms lie within the vertical plane of the outer edges of the coiled springs, so that the hooks will not project beyond the same and increase the width of the bed spring when not in use. Further, in this retracted position the hooks are out of the way where they do not interfere with the handling of the spring and are not liable to become broken or bent out of shape in crating and shipping the same. As the arms are swung outwardly the connecting bar D and its hooks are moved uniformly away from the side edge of the frame and the width of the frame may thus be increased as desired, until the arms reach the limit of their outward movement when they extend parallel with the slats of the frame.

length with the side rail of the bed when the 'with the rails of the bed and this can be done Without trouble at the same time that they bed spring is being placed in positon in the bed. When the hooks are once in engagement with the rails of the bed, they yvill securely hold the bed springs in their proper position therein,`and there are no partsY Which require to be fastened or tightened. for this4 purpose.

i' The construction of the adjustable supporting means is a very simple and ineX pensive one and can be applied to various types of bed springs in common use. The extent of adjustment depends upon the length of the radius upon Which the pivoted supporting arms turn and these arms can therefore be constructed so as to give a greater or lessadjustment to the bed spring, as may be desired.

I claim as my invention:

1. In a bed spring, the combination With a rigid spring frame, of bars arranged 'substantially parallel With the opposite sides of said frame and adapted to extend length- Wise over and be supported by the rails of a bed, andV a plurality of arms connected to said frame and to vsaid bars by vertical pivots for supporting said spring frame from the bed rails, whereby said bars can be movedfhorizontally toward' and from said iframe to suit beds of different widths and are maintained parallel With the sides of' saidk frame andl said bed rails.

"2. In a bed spring, the combination with a rigid noncollapsible supporting frame and a plurality of upright coiled springs which overhang a side or' said frame, of a plurality of supporting arms pivotally secured to the side of said frame, and a rail-engaging member pivoted to said supporting arms, said arms being freeto turn on said frame about aXes substantially perpendicular thereto to permit the rail-engaging member to be swung to positions in which it lies Vsubstantially Within the planeof the outer edges of said upright springs and to positions in which it projects beyond the same, said members being at all times parallel to the side of the frame, substantially as set forth. y

3. In a bed spring, the combination With a rigid supporting frame, of ai plurality of parallel supporting arms pivotally secured at their inner endsto the frame at one side thereof to turn about axesy substantially perpendicular to the frame, a connecting bar pivoted to the outer ends of said arms, said arms being free to turn in unison on said frame to permit said bar to be moved toward and away from said frame, said arms v.being parallel to each -other and said bar being parallel to said frame in all positions, and rail-engaging hooks carried by said bar, substantially as set forth.

t. In a bed spring, the combination of a rigid frame comprising transverse slats and longitudinal connecting members, of a plurality of parallel supporting arms pivotally secured to the ends of said slats to turn about axes substantially perpendicular to said slats, said arms having intermediater portions bentupwvardly rfrom said slats and outwardly. projecting ends substantially parallel to said slats, and a rail-engaging bar 'pivoted to the outwardly projecting ends of said arms, said arms being free to turn in unison on said slats to permit said rail-engaging bar to ybe moved 'towardl and away from said frame, said arms being parallel to each other and said rail-engaging bar being substantially perpendicular to said slats for all positions of said arms and bar, substantially as set forth.

l/Vitness my hand this 16th day of June,

CHARLES HULPIAN.
