(o1. sa es) 1 Claim.

This invention relates to pads'as employed in pressing machines used in cloth working, laundering or tailoring establishments, andparticularly to pads made from resilient material.

A particular object of the invention is to so construct a pad of the character referred to that it will stand up under the constant pressures applied thereto during pressing operations, this being accomplished by the method'of constructing the pad as herein set forth.

The pressures used in pressing machines are such that they have a tendency to break down the material of the pad after constant use and in order to prolong the life of the pad, I have constructed one with transverse windings and encased ina wrapper which prevents the undue spread of the pad and also provides a pad which is compact, is resilient and retains it resilience under prolonged applications of pressure and which will be built up in its central section so that it can be initially compressed in manufacture to prevent subsequent pressures from breaking down the strands of the material thereof. V

In constructing my improved pad,-I construct a filler pad and then encase the same in a wrapper, the open edges of which 'are pinched closed so that the pad is symmetrical in shape and size; the filler pad being wrapped longitudinally and transversely with a coarser material than that from which the body of the filler is made; The filler pad is subjected to an initial material compressing pressure of about twice the pressure that the pad would be subjected to inworking operation. After this initial pressure is applied the filler pad is inserted or encased within an envelope made from the same resilient metallic material, such for instance as steel wool, as the filler is made from. V

Encasing the filler pad in the outer covering pad section or part is accomplished by providing a larger flat mass of the material which can be folded over the filler pad and subjected to a binding pressure which pinches the edges of the enveloping mass to securely hold the filler in in the accompanying drawing, in which:

Figure 1 is a plan view of a filler pad constructed in accordance with my invention and showing the die shaped mass of resilient metalhe material wound longitudinally as Well as latorally with a heavier strand of material for the purpose of keeping the "pad from spreading, Figure 2Qis across section taken on the line 2- 2ofFigurel, 1 Figure 3 is a planview of 'a modified form of the filler pad in which spaced longitudinal windings are employed' Figure 4 is a section on the line 4-4 of Figure 3, Y I r Figure 5 is a plan view of the outer pad cover or closure showing in outline, the fold lines along which the edges'of the cover or outer pad are turned in, v V

Figure 6 is an enlarged section taken on the line 6--6 of Figure 5 showing how one edge of the'cover pad is turned and pinched to close in the inner pad, --.Figure '7 is a plan view of another. form of cover pad made with flaps to envelope the inner pad at the ends thereof, oneside being folded,

Figure 8 is a plan view of the pad shown'in' Figure 7, but illustrated in complete foldedposition, and

Figure 9 is an enlarged cross section on the transversely with narrow and wide wrappings II and I2 of heavier strands of steel wool than that employed in making the mass N] of thepad. The side wrapping 12 not only effectively holds the pad in shape, but gives body thereto which prevents distortion of the pad in use. The pad is wrapped longitudinally as at I3 with the same wide wrapping of heavier strand steel wool material as that employed in the body of the pad. This wrapping I3 is made along the longitudinal centerof the pad 'so that it reinforces the same and prevents breakdown of the inner pad, which is designated in its entirety as at I4. The pad being thus wrapped is thicker through its center and will stand up under applied pressing pressures longer than the mass would by itself. When this inner pad is finished to the wrapping, it is subjected to a pressure in pounds per square inch,

which is about twice the normal working pressure used in pressing machines.

The inner pad is arranged to be placed within an outer pad or cover pad l5 which consists of a large mass l6 of steel wool or the like which is initially subjected to the same pressure as applied to the outer pad in a suitable shaping dieand onto which the pad first made is placed.

Then the edges of pad l are folded as indicated by the fold lines l6 along the edges and folded centrally as at H overthe inner pad to form an envelope thereover. The pad so combined is then placed in a machine die and the edges are pinched together as at l8 to mat the material to form a closure along the edges at 19; so that no enlarged edge of the pad on one side is evident, the pad having a neat symmetrical appearance so that it can be readily may be of ribbon like structure or like cords covered with the fabric as is usual. The use of thereinforced inner pad 14 within the-outer pad 15 provides asolid construction that will withstand pressing pressures without breaking" down and the pad so constructed will have long life and retain its smooth contour. V 7

If desired, I may'usean inner pad of some what difierent construction consisting ofthe mass of wool die-shaped and. then i wound longitudinallypwitlr heavy strand of ;steel'wool in three well defined sections spacedilaterally of the pad,v said windings. 2! giving the pad the necessary, body and confining; the endsthereof under pressure. This pad so assembled :is then subjected to the same initial pressure as above set forth and if desired may be substituted for the pad shown in Figure 1, within the'iouterl pad or cover l5. -1 e In Figure '7; a modified form of outer pad is shown which consists of the mass of wool cut toforma body portion 22 upon which is placed either of the inner pads as shown, the body 22 having en'd flaps 23' andside flap 24, the latter of which is folded over the end flaps afterlfthey have been folded about the pad that'is to be enclosed. This outer pad or cover is in"the'- natureof an envelope and its open edges are pearance desired. The inner pad' gives the necessary body and the entire mass is their subject to the pressureset forthto bind the entire mass into a unitary pad construction. v

.The steps are first the shaping of a mass for the inner pad,- then wrapping the same, then subjecting-the same to compression, then enclosing thesame in the outer pad or wrapper and then. subjecting the whole to the pressure desired to pinch the edges closed and unite the pad bodies. 0

It. is to be understood that the masses of wool employed may be, of any desired coarseness or density depending upon the use to which the pad is to be put and the winding. strands andithe wrapping may be done laterally the entire lengthof the pad and longitudinally the entire width of the pad if desired.

My invention is not to be restricted to the precise details of construction and order of steps set forth as it is understood changes may be made therein without departing from the invention or sacrificing the advantages derived of longitudinally spaced transverse wrappings of than employed in said inner pad mass, said mass pinched closed to give the pad the finished ap- V and wrappings'being shaped under pressure, a cover pad comprising amass of steel wool shaped under pressure and presenting abody portion, flaps at the oppositeen'ds of the body portion and a side flap at one side of said body portion substantially equal:- in area 'to saidbody portion, said side and end flapsbeing folclable over and onto the: inner pad when: the latter is placed on the body portion and both the inner and cover pa'd being united under pressure; 1
