' This invention relates to spring pads,

such as are used on garment and laundry pressing machines, and has for its object a particularly simple and economical spring pad construction by which the-springs are secured to the .base plate at like ends and at their other ends are secured to the covering for the pad in order to prevent the springs from. displacement.

'The' invention consistsin the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference hadto the accompanying drawings in which like characters designate parts all the, views.

Figure 1 is a fragmentary sectional view .-'mentary plan view and an inverted frag m entary plan view of the connection bo tween-the springs and the base plate.

Figure 5 is a detail view of the rivet connecting the springs to the base plate. y

.This 'spring'pad construction comprises generally a base plate, coil springs mounted on 'the base plate, the springs being constructed in pairsand the end coils adjacent the base plate being formed with integral lateral extensions or arms, whichoverlie.

the baseplate and which continue into the lowermost coil of theiother spring of the pair and suchconnccting .arms or exten sions are secured between the springs of each pair to the base plate.

Preferably, the springs/ are arranged in of pa1rs, each group being here shown as consisting of two pairs arranged wlth their connecting arms or extensions crossing each other, and such arms being secured to the base plate at their crossing points.

The invention, also, includes means forming a part of the springzitself for connecting or interlocking the springs with the covering of the pad, sothat the springs are held from lateral displacement and from shifting relatively to the cover and rela tivelyto the base' plate.

Spring pads, such as are used in garment and laundry pressing machines, comprise generally a base plate, coil springs mounted on the baseplate, and a covering overlying corresponding springs.

the upper ends of the springs, the covering consisting of a layer of felt, a wrapper of duck or canvas and layers of other material,

and, also, include a top plate, which is perforated, this top plate being usually a sheet of fine wire mesh.

As the pads are usually mounted on the lower back of a pressingmachine', it ismoreconvenient to consider the springs as rojecting upwardly from the base plate,

although it will be understood that the pad may be used on the upper press head, in-

which case, the springs will project downwardly from the base plate, or in some other instances the pad may be mounted on the periphery of a drum or cylinder.

1 designates the, base plate, 2 are the springs mounted on the base plate and secured at their lower ends thereto, and 3 designates generally the covering and wrapper including the perforated or wire mesh plate 4 overlying the upper ends of the The springs 52 are arranged in pairs and the lower coils of the springs of each pair, that is, the coils resting on the base plate are formed with lateral or tangential extensions or arms 5, which arms are integral with or continue into thelower coil of the other spring of the pair. These arms or extensions 5 are secured between the springs to the base plate 1. Preferably, the springs are arranged in groups consisting oftwo pairs of springs andthe arms or extensions 5 are arranged, so that they cross and are secured to the base'plate at their crossing points.

Preferably, the arms-or extensions 5 are secured-tothe base plate by means ofa rivet .6 provided with prongs 7, here shown as four in'number, the prongs being arranged astride the arms .5 at their intersectingpoints and extending through a hole 8 in the base plate and have their ends clinched at 9 on the lower face of the base plate. Thus, a plurality of springs is attached to the base plate in one operation.

The springs are interlocked with the covering and held from lateral displacement at their upper ends by interlockingthe end coils with the covering or with the wiremesh 4. As here shown, the upper end coils are formed with upwardly extending prongs or shoulders 10, which interlock with or hook into the covering or which extend into the perforations or interstices of the Wire mesh. i s l This pad is particularly simple and economical in construction, in that a plurality of'springs can be attached at the base plate in one operation and further, in that the springs automatically interlock and" hook into the covering or the'wire mesh when the covering or wire meshis applied to the upper end of the springs.

What I claim is:

1. A spring pad construction, comprising a base plate, a group of springs, each group comprising a plurality of pairs oi springs, the end coil of one spring of each pair having a lateral extension continuing into the end coil of the other spring of the pair, such extensions of the plurality of pairs crossing each other, and means for connecting said extensions to the base plate at their crossing point,- said means comprising a rivet formed with a head and prongs projectingfrom the head, the prongs being arranged astride the extensions at their crossing point and extending through the base plate and clinched thereto and a covering over the upper ends of the springs.

2-. A spring pad construction for pressing machines comprising a base plate, coiled springs mounted on the base plate and hav ing-outward extensions of their lower coils overlying the plate, and means for securing said extensions to the plate, a covering over the upper-ends of the springs, the springs having means selfcontained therewith for hooking into the covering and thus holding the springs from lateral movement.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 10 day of J une'1924.

GEORGE E. RYAN.
