SPRING-PAID CONSTRUCTION.

Application filed September 1, 1826. Serial No. 132,965.

This invention relates to spring pads such as are used in garment and laundry pressing machinery and in other situations and has for its object a spring pad construction bywhich any inequalities in the thickness of the article being pressed are compensated for and further on account of the arrangement and character of the springs a spring pad can be built at a relatively small price and is particularly eflicientand durable in use.

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.

Figure 1 is a'longitudinal sectional View of a, spring pad embodying my invention, the

same being shown as applied to the lowerpressing element or buck of a conventional garment or laundry platen pressing machine.

Figure 2 is a fragmentary plan view of the spring pad, the distance or spacing between the springs being magnified.

Figure 3 is a fragmentary detail view ill ustrating the endwise movement of the supporting element or plate during compression of the springs.

Figure 4 is a fragmentary longitudinal sectional view showing the action of the spring coils when compensating for the inequalities in the article being pressed.

Figure 5 is a detail View, partly broken away, illustrating the way in which the ends of each spring are connected to the supporting element or plate.

Figure 6 is an end view looking to the right or left in Figure 2.

Figure 7 is a fragmentary elevation showing this spring pad applied to the roll of a flat work ironer.

Figure 8 is a vertical sectional, view of parts seen in Figure 7 Figure 9 is afragmentary sectional View of the form of spring shown in Figure 1 applied to the roll of a flat work ironer, the endwise movement of the intermediate supporting element being shown in dotted lines.

Figure 10 is an edge view of this spring pad applied to a cufi ironer, the spring being shown in its operated position.

Figure 11 is a detail view illustrating the connection of the spring shown in Figurescline to their supporting surface so that the individual coils swing toward said supportmg surface when the compressing force is .applied sidewise to the coils of the springs tending to distort the coils into aflattened or elliptical form.

The springs may be applied to a flat surface or a cylindrical or rounding surface. In

the construction in Figure 1, springs 1 and 2 lie on their sides on opposite sides of a supporting element or plate 3 interposed between the springs, the springs being secured at their ends to the plate so that they are under tension and their coils are inclined relatively to the plate as'shown in Figures 3 and 5. Preferably, as seen in Figure 5, the upper portion of one end coil which upper portion is farthest removed from the plate is pulled down to the plate as at t and secured at 5 thereto while the coil 6 at the other end of the spring is secured to the plate at the portion thereof normally contiguous to the plate. Owing to the fastening of the springs to the plate, the coils'are caused to take an incline.

'In Figure 1, the spring pad is shown as applied to a fiat face or to the buck of a pressing machine. The lower layer of springs lies on the face of the buck and the upper layerof springs is covered by a suitable padding as a sheet 7 which is overlaid by a cloth or fabric 8. The springs are arranged nelatively close together and usually the springs on one side extend in the same direction as the springs on the other side instead of crosswise, that 1s, in the construction shown in Figure 1, the springs on the upper and lower side of the plate 3 extend lengthwise of the plate. One layer may however extend crosswise of the plate. During compression of the springs or the coils thereof, the coils swing from their normal incline into an incline nearer a horizontal plane and in so doing the portions of the coils engaging the plate push the plate endwise as seen in dotted lines at 9 in Figure incline in opposite directions. Such movement of the plate avoids undue slip and friction between the springs and the plate when the head com'pressesthe work on the buck.

As seen in Figure 4 when an article is being pressed, the thicker portions as the seams 10 or buttons or other projections as 11 compress only the underlying coils as at 12 of the upper springs 1 while the springs 2 below the plate resist the total compression,

that is, the coils ofthe uppermost springs equalize for. inequalities in thickness of the "articles being pressed as well as coact with the lower layer of springs to resist the total compression. During the compression of only part'of the coils of the springs no endwise 'm'ovement'of the plate takes place.-

v In Figures 7 and 8, the spring pad is-shown as applied to a roll of a flat Work ironer.

13 designates t-heroll supported at its ends by heads as 1 1 having axles 15. 16 designates the springs overlying a cylindrical plate 17 and secured at 17 at their ends thereof with their coils inclined as clearly seen in Figure 8 relatively to the cylindrical plate. The springs'are enclosed by the usual padding 18 and cloth 19.

In Figure 9, upper and lower layers of springs are shown which thrust against a cylindrically movable cylindrical plate 20, the movement of the plate during compression of the springs being shown in dotted lines inFigure 9. The action of the springs to compensate for inequalities in the thickness of the work is shown at 21, Figure 8.

22 is the usual heated so called shoe of a fiat work ironer.

In Figures 10 and 11, the spring pad is shown as applied to the buck of a cutf ironer, that is, a buck having inclined sides.

23 designates the springs overlaid by a padding 24 and a fabric or cloth 25;

In Figure 10, the buck is formed A shape and preferably the springs extend from the lower ends of the A formation over the apexv cheaply compared with the cost of other spring padding.

What I.claim is: A spring pad comprising a supportingelement, coiled springs lying on their vsides on said element, the springs being secured at their ends to said element and arranged with theifcoils inclined relatively to said element, the intermediate coils of the springs thrusting against and being unsecured to and slidably engaged with the supporting element. v/

In testimony whereof, I have/hereunto signed my name, at Syracuse, in the'county of Onondaga, and State of New day of August, 1926.
