' HARRY ALBERT STEELE, OF SYRACUSE, NEW YORK, ASSI GNOR TO 'L HE PROSPERITY v UNITED STATES PATENT OFFICE,

COMPANY INC., 01 SYRACUSE, NEW YORK, A-COBPOBATION F YORK 'srnmc ms consrnoc'rronr Application filed. August 3, 1928, Serial No. 297,192. Renewed December 12, 1930.

This invention relates to spring pads such as are used in pressing machines, as garment and laundry platen pressing machines, and drum presses as mangles, flat work ironers and the like, and has for its object a particularly simple, economical and efficient means for securing together a large number of coil springs.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth-and claimed.

In describing this invention, reference is had-to the accompanying drawings in which like characters designate corresponding parts in all the views.

' A particular object of this invention is I to devisean improved-spring pad construction over that shown in my copending application Sr. No. 274,790, filed May 23, 1928. Figure 1" is a plan view of a spring pad embodying my invention, the usual wrapper.

and layers of cloth padding and screen being omitted.

Figure 2 is an edge view of parts seenin Figure 1.

'The sprlng' pad comprises a plurality of rowsof coiled springs, the springs of each tween the springs of the rows by endwise' row being connectedtogetherso that each row is a unit in itself and means extending transversely of therows and insertable bemovement to secure the rows together having means as deflections for interlocking" withthe springs of the different rows during the insertion thereof into assembled position transversely of the rows;

1 and 2 designate alternate rows of springs. 3 designates the coiled springs of each row.

As here illustrated, the upper end coil of ,each intermediate springis connected by a continuation 4 of such end coil to the upper end coil of the next.adjacent spring on one side thereof in the same row and the lower coil of each spring is connected by a similar continuation 5 of the lower coil-of the adjacent spring in the same-row on the otherside thereof. i By intermediate springs is meant the spring between the two end springs of the row.

The means for securing the rows together comprises strips 7 and preferablysheet metal strips, insertable transversely of the rows between the springs thereof, each strip having coils on opposing sides of the springs of the difl'rent rows.

In the illustrated-embodiment of my invention, the strips 7 are formed with rounded corrugations so that the projections are in the form of arc-shaped deflections 8. These strips are also formed with deflections. or corrugations 9 extending oppositely to the deflections 8 and alternating therewith and conforming to the-c rvature of one of the two 7 adjacent springs o the same row.

, In' assembling the springs into a pad structo contain'the required number of springs and a number of rows laid side by side, the

ture, the-rows are cut off at the desired length length and the number of the rows depending upon the size or area of the pad.

The corrugated strips 7 are cut off at the right length ,and then are inserted transversely between the rows and when fully inserted", the; deflections 8 hold the-rows from displacement relatively to each other. After the strips are inserted, the ends 10 thereof may be bent to extend farther around the springs thereto than the intermediate corrugations; Owing to the transverse strips which are applied by being inserted endwise between ,the springs of the different rows, a spring pad of any size is assembled readily with minimum labor.

-' In'use, in apressing machine, the-body of' springs is usually overlaid with a perforated or wire mesh screen, a layer of fabric 'padding, and a wrapper or cover.

What I claim is: v v 1. A spring pad comprising rows ofcoiled springs, the springs of each row being connected together whereby each row is a unit in itself and means extending transverselyof the rows between the spr'ngs of the rows for holding the rows from'di lacement relatively to each other, said means comprising strips 7 having deflections extending into the spaces between springs of the different rows. I

loci

2. A spring pad comprising rows of coiled springs, the springs of each row being connected together whereby each row is a unit in itself and meansextending transversely of the rows between the springs of the rows for holding the rows from displacement relatively to each other, said means comprising strips having deflections extending into 'the spaces between springs of the different rows, said deflections partly conforming to the contour of the springs of adjacent rows.

3. A spring pad comprising rows of coiledsprings,' the springs of each row being connected together whereby each row is a unit in itself and means extending transversely of the rows between the springs of the rows for holding the rows from displacement relatively to each other, said means comprising strips having deflections extending between and partly conforming to springs of adjacent rows and other deflections extending between springsof the rows conforming to the contour of oneof two contiguous springs of each of the rows.

4. A spring pad comprising parallel rows of coiled springs, each intermediate spring of each row being connected at its lower end to the lower coil of the spring on one side thereof in thesamerow and the upper end coil of said spring being connected to the upper coil of the spring in the same row on the other side thereof whereby each rowisa unit in itself and means insertable transversely of the rows between the springs thereof and having deflections extending partly into the spaces between the springs of the different rows and partly conforming to the curvatures of the coils of the opposing springs of adjacent rows.

5. A spring pad comprising rows of coiled springs, means connecting the coils of the springs of each row together whereby each- I row is a unit in itself, and means extending transversely of the rows and between the springs of the rows and engaging the coils of the springs for holding the rows from displacement relatively to each other. 6. A spring pad comprising rows of coiled springs, means connecting the coils-of the springs of each row whereby each rowis a unit in itself and comparatively stifl' strips extending transversely of the rows between the springs of the rows having means for interlocking with the coils of the springs of different rows.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New York, this 27th day of June, 1928.
