4Patenteiad ept. 8, 1931l UNITED STATES PATENT OFFICE CLARENCE M. CLARKE, OF SYRACUSE, NEW YORK, ASSIGNOR TO UNITED. STATES HOFF- i MAN MACHINERY CORPORATION, .0F NEW YORK, N. Y., A COR-POIRATION 0E DELA- WARE GARMENT PRESS Application led March 26, 19291 'Serial No. 350,089.`

This invention relates to garment presses and particularly to toggle mechanisms for actuating the same.

The prime purpose of the invention is to provide a commercially practicable linkage, capable of exerting great force and. offering a wide opening movement of the press and compact arrangement. j

The linkage comprises two thrust links combined with a floating member to which the links are pivoted at spaced points, so that the ioating member may be brought into thrust alignment with the .links by a .com-

pound swinging and rotating movement ofranging the parts may be made to form a.

secondary toggle with the'movable member, and thus enhance the force multiplying func tion of the irst toggle;

Various structures for supporting the buck, and guiding the movable head rela-v tively thereto are known, and the linkage her in disclosed is generally applicable, but will be described as applied to a conven tional t pe of press in'which `ythe head is carried y a vertically swinginglever.`

In the drawings, E Figure lisa side elevatlon of a press with parts broken away to show the construction. Figure 2 is a section on the line 2-.2 of Figure 1.

Figure 3 'leverror'yoke 12, carrying the usual press head 13with hand grip 14. The yoke 12 is a section on the. line l.off

is a section on the linea-1 ofgenerally by thenuf` 17. The upper main toggle link is longitu.

dinally compressible and is adjustable-as to length, this being a known construction. 'It includes a head 18 j ournaled in the trunnions 19,1i`xed in yoke 12 by the set'screws 21;

a thrust. rod 22 swiveled in the head 18 and rotatable by a hand wheel 23; a thrust collar 24 pinnedto rod 22; a spring seat 25' into which rod 22 is threaded; a guide stem 26 fixedr in spring seat 25; a combined spring seat-and forked fulcrum block 27 yguided on said stem and a compression spring 28 s1.; rrounding' said stem` and reaching between .said spring seats.

The lower end ofgthe-upper main toggle link (part 27) vis hingedby journal pin 29 andthe upper end of the lower main toggle link 17 is hinged by journal pin 31, to a.

floating-thrust member 32 having an .arm 33. The pins 29 and 31 are spaced-apart in this`^ member a substantial distance and the arm 33 extends in a direction generally transverse to the line connecting the centersl of the journalpins. Near itsf end the arm 33 carries a journal pin 34;

A lever 35 is pivoted between its ends at 36 to the frame \6. One end is pivoted to the pin. 34, the other end is connected by a ten- `sion linkl37 (shown as adjustable in length) to a foot lever 38 which is journaled on pin 16- at the rear of the machine 'and terminates 'at the front of the machine in a foot pedal 39.

- f The fulcrum points on the-frame fare so located and the moving parts are so formed d dimensioned, that at the -limit of downard motion of lever 38, the journalpins- 16, 3-1 and 29 and the'trunnions 19 lie-in a straight. line or substantially so (full Vline position,"Figure l) and lever 35 aligns with arm 33. Thuswthe press locks closed in a familiar manner.

The foot lever 38 may .be raised sufficiently to break the' toggle strut action by. means of a kick-off pedal 41 pivoted'in the frame 6 at 42 and having a rearward extension 43 which underlies lever 38. The press opening movement of the linkage is arrested by collision of narm 33 with buffer 44 on lever 38 (see y, dotted line position, Figure l).

Various changes may be made in the specitic details of the linkage, and as stated it is generally applicable to garment and like presses of various known types.

What is claimed is:

l. In a press, the combination of a fixed frame; a fixed pressing element supported thereby; a second pressing elementl cooperative therewith; a pivoted supporting memher for said second pressing element; a link pivotally connected at one end to the pivoted supporting member; a link pivotally supported on the fixed frame; a thrust member having spaced pivotal connections with the links and having a third pivot displaced from 5the line connecting its pivot connections with the two links, the four pivotal connections of the two links being substantially aligned when the press is closed; and

means for moving the third pivot of the thrust member in a definite path to cause said four pivotal connections lof the links to move toward and away from alignment.

2. In a press, the combination of a fixed frame; alfixed pressing element mounted thereon; a second pressing element cooperative therewith; a pivoted support for said second pressing element; a link pivotally supported on the fixed frame; a link pivotally connected tothe pivotal support for the second pressing element; a thrust member having spaced pivotal connections` with the links, and having a third pivot displaced `from the line connecting its pivot connecmember guided on said frame to move in a definite path; a head carried by said member into and out of pressing relation with said buck; a pair of links, one pivoted at one end to said fixed frame and the other pivoted at one end to said movable member; a thrust member pivot-ed at spaced points to the other ends of said links and having an arm extending laterally relatively to a line connecting said spaced points, and having a third pivot; a lever pivoted to the fixed frameand to said pivot; and means forv swinging said lever, the parts being so dimensioned and the pivot connections being so located that the lever and said arm swing into substantial alignment as the four pivot points of the first two links approach substantial alignment.

In testimony whereof l have signed my name to this specification.

CLARENCE M. CLARKE.
