A SPRING- PAD.

To all wkomit may concern."

Be it known that I PHILLIP KRAKAUER,

ments in Spring-Pads, of which the following is a specification'.

This invention relates to improvements in spring pads, such as spring seats, -spr-ing cushions, spring mattresses and the like.

The object of this invention is theproviand durable spring pad f which will conform to the shape of the body pad.

in contact therewith without materially affecting the shape of the remainder of the A further object/of -this invention is the provision of a spring unit which is so con structed as to be entirely 'independent of the sprin units in the remainderv of the pad,

Where y compression of any of said units does not affect the vnormal position of the remainder of said units. f

A still further objectof this invention is vthe provision of spring units' which can 'be rapidly and`cheaply'made.

'Io attain theseobjects, I employ `the arrangementandA combination of parts shown.

in the accompanying .drawingsand hereinafter described and claimed.-

In the drawings, k. Figure 1 isa plan view of the parts comprising one f the'spring units before the spring portionl is incased.

Fig. 2 is a plan view similar to Fig. 1'

showing the spring partly incased. Fig.l 3 is an elevation of Fig. 1.

- Fig. 4 is an velevation of Fig. 2.

Fig. 5' is a perspective 'view of oneof the spring units and Fig. 6 is a vperspective view of a spring pad, part 'of-,the outside casing being removed to "show the arrangement of l -the spring units- In the practical embodiment of my .invention, I prefer to construct'thespring Munit 5 by first placing the coiled or 'helical .wireV` spring 2 near the center of af piece of ex'i'- ble material such as the square of clothvl (Fig. 1).. The opposite corners 8f of said square 1 are then' brought together over the top of the spring and tiedj into the double. knot 3, suicient Atension being put upon said corners 8 to compress spring 2 the desired amount The remaining corners of square 1 are similarly brought Specification of Letters Patent.

together and tied to forni the 'complete spring unit 5;

A. series of said spring-units 5, each com-. lprising the spring 2 and the casing 1 may be arrangedI in any 4suitable manner in spring pad 7. One method of arrangement is shown 1n Fig. 6, in which the units 5 are placed side by side to 4form a series oi' rows at right angles, the outside casing 4 of pad 7 being then drawn over all the spring units and suitably seanied.

Connecting threads. as 6 may be loosely toA passed through casings 1 to preventn de-` rangement of spring units 5, though said 'Ill threads may be omitted without detracting from the ecacy of -my invention.

It is readily seen that each of the spring units 5' is entirely independent of the remainder of s aid units and that depression of any of said units mustbe by pressure substantially in the line of the axis of said.

unit; from which it is obvious that part of vthe seat, cushion or mattress in which my construction is Iused, which is` actually pressed against, will be depressed, the remainder retaining its normal position. more perfect fit to the body is therebyobtained, insuring comfort without disturbing any other occupant ofthe same seat, cushion vor mattress.'

It is also seen that depression of the .spring unit simply ywrinkles casing 1, which again assumes its normal position upon the release of the pressure on the spring, and

that ,two thicknesses of cloth are provided.- ybetween the springs of any two units, thereby insuring long wear. l

It is obvious that, any piece of flexible material provided with corners for tying may 3.'A spring unit for a spring pad, comprising a coiled wire spring and a piece of iat ' end of said cloth, the spring resting on the piece of cloth near the center thereof and being compressed,and the opposite corners of said piece of cloth being tied together over the end of the compressed spring to form a casing for said spring.

4. A spring unit for a spring pad comprising a coil spring and a piece of flexible material having corners thereon, the opposite of said corners being knotted over one spring for compressing said spring and for forming a casing for said spring, said one end.

casing being partly open at v 5. A spring pad comprisin a series of 15 spring units,k means for loose y connecting said units for preventing derangement of said units, and an outsidecasn for said `units; said spring units comprisln coiled Y Wire springs, and iexlble casings or each 20 of said springs formed by knott'ing the 0pposite corners of a piece of 'cloth together over the endof. the spring.
