SPRING-PAD CONSTRUCTION.

Application filed February 20, 1928. serial'li'o. 89,785.

This invention relates to spring padoonstruction, particularly spring pads used in garment and laundry pressing machines and has for its object a spring pad which 1s 5 particularly simple and economical in construction, yielding in its action to conform ,to any inequalities as buttons and the l1ke in the article being pressed and highly eili-' cient and durable in use.

The invention consists in the novel tea- ,tures and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference 1s had to theaccompanying drawing in which .|5' like characters designate correspond ng parts in all the views.

Figure 1 is a plan-view, partly broken away, of a spring pad embodylng my 1nvention.

Figure 2 is an edge view, partly in section, of parts seen in Figure Figure 3 is 'an end vlew left in Figure 1.

I This spring pad comprises, generally, up- 25 per and lower plates, coiled springs between the plates, a resilient abutment for receiving the pressure and relievin the springs of the compression after they h vebeen compressed 'a predetermined amount, the s r1ngs being 3 unattached to either the top or ttom plate and the abutment serving to holdthem 1n upright position and means enclosing the foregoing parts for holding them in assembled relation. Some ofthe foregomg features may obviously be omitted.

1 and- 2,..are respectively the top and bot- "'tom plates j 3 are Springs inserted between the .plates and thrusting at their ends agalnst 4 the plates.

4 is the yielding abutment for relieving the springs 3 of compression when they have been compressed a' predetermined amount, this abutment 4 being a base formed with holes 5 therein in which the springs 3 are seated, the lower ends of the springs thrusting against the bottom plate The abutment 4 thus holds the springs in uprlght position as the springs are'not attached to either the top or the bottom plate. Thls abutment 4 is preferably formed of matting or a sheet of felt with the holes 5 punched therein. The top plate is also of felt or other porous materlal as well as the bottom plate 2. If desired, the base 4 and bottom looking to the 'lower plates, a base member resting on the lower plate and formed 'withlholes therein plate 2 may be integral with each other. These parts as the top plates 1, 2. springs 3 and base 4 are held from lateral displacement or in assembled position by a wrapper or casing 6 shaped to fit them. This wrapper or casing 6 is in the form of a sack having upper and lower fiat sides 7 8 and an edge wall 9 in theform of a band of a width substantially equal to the height of the spring pad. .In other ,words, the sack is made to fit the pad snugly.

The spring pad is here shown as tapered, andas having rounding ends and also as open at its larger end for permitting the insides of the pad, that is, the top and bottom plates 1, 2,'springs 3 and base 4 to be inserted therein. The pad is held closed at its open end by a suitable cord 10.

The top and bottom plates 1, 2 as well as the sack or the top and bottom sides 7, 8thereof are of material of such porosity as to permit steam to be passed therethrough.

In operation, when t e pad is placed on the lower buck of the pressing machine and the head of the machine brought down on the garment thereon, the springs are compressed until their upper ends become even with the upper surface of the base 4 or until the top plate 1 comes down on the base 4, the latter forming a spring pad to which the final heavy pressure is applied. Also any portions of the top plate can yield and embed into the base 4. For instance,

buttons on a garment can be depressed into the to plate 1 and the base 4 will yield or have ormed therein a corresponding depresslon.

L Owing to the construction, no means as rivets and the like are necessary to hold the arts of the pad together but the parts of t e pad can be laid together and inserted in the sack.

What]: claim is: g t 1. "A- spring pad comprising upper and which holes constitute sockets and coiled springs seated in the sockets and resting at their lower ends on the base plate, the springs projecting above the base member, the top plate resting on the upper ends of. the springs. i 2.'.A spring pad comprising upper and lower plates, a basemember resting on. the lower plate and formed with holes therein which} "holes constitute sockets, coiled springs seated in the sockets and resting at t eir lower ends on the base plate, the top plate resting on the up r ends of the s rin and a wra er enc osin the lates, the wfi apper being il i the form (if aflaii; sack open at one edge, base member and springs and holding, them in assembled relation.

3. A spring pad construction comprisin upper and lower plates, springs interposed between the plates and a yielding abutment .with socket holes throughout 1ts area, and

coiled springs seated in said holes, and ex tending beyond a face of the abutment plate, these holes being deep enough to enclose a plurality of the coils of each spring and :hold the spring in upright position without interfering with .the compressing of such springs, the lower coils of the springs being located 'within the holes walls of the holes. I

5. A spring ad comprising a base abutwhereby the springs are held upright by the ment member 1n the form of a thick plate formed with holes throughout its area, and coiled springs seated in said holes and extending beyond a face of the abutment plate, the lower coils of the springs being located within the holes whereby the springs are held upright by the walls of the holes,

the abutment plate being of yielding material.

6. A spring pad comprising a matting of yielding material having socket'holes therein throughout its area, coiled springs seated 'in said socket holes and projectin out of the holes, and a wrapper for hol ingthe parts assembled, the wrapper being in the form of a flat sack entirely enclosing the top, bottom and edges of the matting with the springs therein.

. In testimony whereof I have hereunto signed my name at Idavenport, in, the county of Scott, and State of Iowa, this 5th day of February, 1926.
