This invention relates to "pressing machines, particularly laundry pressing machines in which one-ofthe pressing elements as the lower pressing element consists of a plurality of sections or-members for ironing at the same time, different portions of a. garhas for its object, a particularly simple and 'efiicient construction and mechanism by which the pressure on said members or sec-' tions of the pressing element is distributed or equalized and hence, the pressing or ironing operation made uniform on the parts of a garment, that is, on the neck yoke and the cuffs of a shirt.

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 drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary front elevation of a pressing machine embodying my invention. a

Figure 2 is an enlarged fragmentary view of parts seen in Figure 1.

This pressing machine comprises general-.

ly, coacting pressing elements, one of which is movable toward and from the other, one of said elements, usually the lower element, consisting of a plurality of members mounted to move relatively to each other when unequal pressure is applied thereto by'the other or upper pressing element and means for supporting said members comprising ualizing mechanism for transferrlng the di erential movement of either or any one of said members to the other.

The pressing machine may be of any suitable form, size and construction and as pressing machines of this type are well known, further description is thought to be unnecessary for a complete understanding of this invention.

The machine here illustrated is designed to press the cuffs and the neck yoke of a shirt at the same time, and includes a head 1 and a lower element or buck 2 which is mounted lever 4 is actuated to raise and lower the head 1 by any well known mechanism. The head 1 1s provided with three members or sections 5, ti'and 7 arrangedin a row and being concave 5 111 general form, and the buck2 is formed wit complementary members 8,9 and -10, the latter supported on the buck 2'by the equalizmg mechanism to be presently de scribed. The coacting members 5, 8 and 7, 10 are shaped to iron the cuffs of a shirt while the coacting members 6; 9 are shaped to pressthe neck yoke of a shirt. T

Spring means arehere' shown 'to hold the members 8, 9 and 10 against or, to follow the equalizing mechanism or levers; As here illustrated the springs are of the compression type and encircle studs 11 depending from said members 8, 9 and 10 and extending through'lugs .12 on the body of buck 2, the

springs being interposed between said lugs and nuts or shoulders 13 on the studs.

The equalizing mechanism comprises levers 14, 15 between the members 8, 9 and the members 9, 10 respectively. Each of the levers are fulcrumed between its ends at 16 and has its ends extended upward and pressed against the lower sides of the mem ers 8, 9 and 10. The outer end of the lever 14 presses against the member 8 and the outer end of the lever 15 against the member 10, and

the inner ends of both levers press against the lower side of the intermediate member 9 near the center thereof. The fulcrums 16 are here'shown as screw bolts adjustable to on the lower pressing element when the head 1 is up, the neck yoke being placed on the member 9 and the cuffs on the members 8 and 10, the head is then brought down onto the buck under pressure. If the machine isnicely adjusted, the pressure will be uniform even if the neck yoke is not as thick as the cufis, without action on the part of the equal izing levers. If however, for any reason, the pressure is unequal or forinstance, if the pressure is greater on the cuff supporting members 8, 9 than on the intermediate member 10, the differential movement will be transferred through the levers 14,15 to the intermediate member 10 and press the same upward. Also, if the heaviest pressure is on the intermediate member, the intermediate member will be depressed and force upward the cuff supporting members 8, 9 and thus equalize the pressure. It is generally the case that the cuff supporting membersare more liable to normally receive more pressure than the intermediate neck yoke supporting member 9, and the equalizing mechanism is primarily intended to boost the pressure on the intermediate member.

In machines'of this type heretofore used, the neck yoke is oftentimes not satisfactorily pressed or ironed because of the pressure being greater on thecuff lromng members than V on the intermediate yoke pressing member.

. pressure owing to the equalizing mechanism.

By my invention, all the parts receive equal between the members 8, 9 and 10.

What I claim is z" 1. pressin machine comprising coacting pressing e ements, one movable toward and from the other, one of said elements comprising a plurality of membersmovable relatively to each other when unequal pressure is applied thereto by the other pressing element and equalizing mechanism to support said members'and transfer the differential movement'of either member to the other.

2. A pressin machine comprising -coactin pressing e ements, one movable toward an from the other, one of said elements comprisinga plurality of members movable rela-' tivel to each other when unequal pressure is applied thereto by the other pressing element, means for supporting said members including equalizing mechanism for transferring the differential movement of either memberto the other.

3. A pressing machine comprising coacting pressing elements, one movable toward and from the other, one of said elements com-' prising a plurality of members movable relatively to each other when unequal pressure is applied thereto by the other pressing element, means for supporting said members comprising an equalizing lever fulcrumed between its ends and bearing at its opposite ends against said members.

4. A pressing machine comprising coacting pressing elements, one movable toward and from the other, one of said elements comprisinga plurality of members movable relatively to each other when unequal pressure is applied thereto by the other pressing element, mechanism for transferring the differential movement of either member to the other, and

.in ressin elements one movable toward and frointh'e other, one of said elements comprising a plurality .of members movable relatively to each other when unequal pres-' sure is applied thereto by the-other pressin element, an equal'izin lever between. sai members for transferring the relative movement of either support to the other, and spring means for holding the said members against the levers.

6. A: pressing machine comprising coact' ing pressing elements, one movable toward and from the other, one of said elements comprisin three members movable relatively to each other when unequal pressure is applied thereto by the other pressing element, means for supporting said members and transferring the differential movement of any one of said members to the others.

7. A pressing machi'necomprising coacting presing elements, one movable toward and from the other, one of said elements comprising three members arranged in a row and movable relatively to each other when unequal pressure is applied thereto by the other pressing element and mechanism for transferring the differential movement of the two end members to the intermediate member and of the 'intermediate'member to the end members.

A pressing machine comprising coacting pressing elements, one movable toward and from the other,.one of said elements comprising three members arranged in a row and movable relatively to each other when unequal pressure is applied thereto by the other pressing element and mechanism for transferring the differential movement of the two end members to'the intermediate member and of the intermediate member to either or both of the end members, said mechanism comprising equalizing levers, each fulcrumed between its ends and at its opposite ends bearing on one of the end members and the intermediate member.
