LOUIS H. ERSI-ILER AND MAX HENDLER, OF HUDSON, NEW YORK.

BED-SPRING.

To all whom it may concern:

Be it known that we, LOUIS H. EnsirLEn and MAX HnNnLnn, citizens of the United States, residing at Hudson, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Bed-Springs, of which the following is a specification.

The present invention relates to improvements in bed springs, and has for its objects the provision of yielding means to hold the wire mattress or support suitably taut, such yielding means being adapted to be adjusted from either end of the bed spring, to provide means for preventing the sagging or displacement of theadjustable bar or ele ment secured to one end of the wire mattress without affecting its adjustability, to pro vide means wherebythe several parts of the bed spring may be quickly and conveniently assembled or separated, such parts being adapted when disconnected to be arranged in a compact manner for shipment or the like, to provide means whereby the device is constructed in few and simple parts which may be manufactured cheaply, and to provide a bed spring of the above-mentioned character which is adapted for use in connection with the standard bedstead.

Other objects and advantages of the in vention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a perspective view of a bed spring embodying our invention;

Fig. 2 is a fragmentary longitudinal section, taken on line 22 of Fig. 1;

Fig. 3 is a transverse sectional view, taken on line 3-3 of Fig. 2;

Fig. 4 is a longitudinal sectional view, taken on line H of Fig. 1;

Fig. 5 is a similar view, taken on line 5-5 of Fig. 1; and,

Fig. 6 is a perspective view of the adjustable foot bar or rail.

Tn the drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 10 designates longitudinal tubes included in a frame. These longitudinal tubes have brackets 11 rigidly secured to their ends, such brackets carrying outwardly projecting flanges 12, adapted to engage over the longitudinal Specification of Letters Patent.

sides of the bedstead, or elements secured to the same, as is well known. These brackets 11 are rigidly connected by stationary transverse L-beams 13, or supporting elements. The above described frame is of the usual construction, and adapted to receive and support our improved bed spring.

The numeral 1 designates the spring or wire nurttress or support, one end of which is secured to a transverse rod 15. The opposite end of this mattress is attached to retractile coil springs 16, carried by an adjustable transverse foot bar or L-bar 17, as shown.

The numeral 18 designates upstanding brackets, each of which as shown in Fig. el, is provided with a base 19, and depending eX- teusion 20, carrying an upturned lip 21. The base 19 is adapted for arrangement upon the L-beam 13 while the lip 21 engages beneath this L-beam,the longitudinal movement of the bracket upon the lL-beam 123 being prevented by a bolt 22 or the like. At its u )per end, the bracket 18 carries a horizonta tubular head 21', rotatably receiving the outer smooth portion of a tension element or post 22, carrying a head 23 and extension 24:, which is preferably square in cross section. This extension is adapted for insertion within a socket 25, carried by a crank 26, by means of which the tension element 22 may be r0- tatecl.

The inner ends of the bolts 22 are screw threaded, as shown at 25, and these screw threaded portions operate within screw threaded openings 26 formed in the adjustable bar 17, such openings preferably extending through enlargements 27.

To prevent the adjustable bar 17 from being forced downwardly, which might result in the bending or injury of the bolts 22 and associated elements, we provide a brace 28, which is rigidly secured to each end of the bar 17, as shown at 29. This brace is preferably inclined and is provided at its lower end with a head 30, curved in cross section, for receiving the upper portion of the tube 10, and shdably contacting therewith. It is thus seen that the bar 17 is equipped with two of these braces 28, which do not interfere with the adjustment of the bar 17.

The rod 15 is passed through eyes 31, formed upon the ends of torsional coil springs 82, which are vertically arranged, as shown. The inner ends of these torsional coil springs are provided with eyes 33, square in cross section, for receiving pins 34:, also vioed near their upper ends with openings 41, Which are square in cross section, to receive the pins 3%, which are held against longitudinal displacement therein, by pins 42 passed through transverse openings in its ends. it is obvious that the tension of the torsional, coil spring 32 may be regulated by adjusting the pin 34. The torsional coil springs 82 serve to support one end of the mattress 14:, in a yielding manner, and also serve to hold it suitably taut.

In view of the foregoing description, it is obvious thatthe tension of the mattress 14 may be regulated byturning the bolts 22, which may be accomplished while the device is in use. The several parts of the device are readily separable so that they may be separated for the purpose of shipment, or so that a new part or element may be substituted foran old part, in case the same becomes broken or worn.

It is tobe understood that the form of our invention herein shown and described is to be taken as a preferred example of the same and that Various changes in the shape, size, and arrangement of parts may be resorted to Without departing from the spirit of our invention or the scope of the subjoined claim.

Having thus described our invention, we claim In a bed spring of the type described, a frame comprising longitudinal tubes and transverse L-iron bars secured to said tubes at the ends thereof forming sup1: orts,brackets mounted upon one of said supports having a fiat face adapted to rest upon one flange of said L-bar and a depending portion adapted to engage the other portion of said L-bar, said depending portion being provided with a. lip adapted to engage the edge of the flange, an adjustable L -ba1-, enlargements formed on the vertical flange of said adjustable L-bar having screw threaded openings formed therein, horizontal tubular heads formed on said brackets, rotatable members mounted in said tubular heads and provided with screw threaded portions engaging the threaded openings in said adustable bar and braces secured to the horizontal flange of said adjustable L-bar having curved lower faces slidably engaging said longitudinal tubes said adjustable L- bar being provided with spaced openings in one flange thereof for the reception of a securing means for a spring.

In testimony whereof we afiix our,signatures in presence of two witnesses.
