Thisinvention: relates to pressing machines, particularly shirt pressing machines and has for its; object a particularly simpleand ci-V cient means for moving one of. the pressing elements laterally slightly duringythe closing of they press head in order to pressfthe shirt close toftheneck band. y 1

The invention consists in the novel features and in the combinationsand` constructions hereinafter setforth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views... y Y Y Figure 1 isI aside elevation of a pressing machine embodying my invention, the neck band.E holder being omitted. Y l

Figure' is a diagrammatic view illustrating the laterall movement of the head1 rela.- tively tothe neck band holder as the head closes'.

Figure 7 is an enlarged fragmentary detail Y view of the connection betweenk the yoke and the head.

In pressing shirts, the neck band is fastened around or clamped against a neck band holder and in ordinary pressing machines, the Vhead does not press close up to the neck band andl the operations, if done at all, up close to the neck bandi, must be doneby al handiron.

ThemachineI constituting the subject matter of thisrinvention comprises, generally, upper and lower cooperating pressing elements, the lower element being provided with the usual neck band` clamp.` at one end'and the upper element with the usual cut-out compleinentalK i 1928'. Serial No.=315,705.

The carrier for thelhead is'here shown` asa yokeor` lever pivoted between itsiends at' I to an upright 7 rising from-the frames lever'carries the head2 at its frontend.

The actuating mechanism in addition t0 the carrier or lever 5 may be of any suitable form, size and construction, and -is here shown aspower actuated mechanism including an oscillating cylinder 8 having a piston movablev therein,;the `rod 9 of lwhich is pivoted to onearm of a bell crank lever" l0 which is pivotedl` at. 11 at its angle tothe base of thev frame. ,The other arm 12 .of the bell crank lever extends upwardly and. is` pivoted atl?) y to the lower end of a link 14 toform a toggle, l Vthe upper end of the link 14 being pivoted at 15 to the rear arm of the yokelever. The piston is singleV acting and the pressis opened, when theV motive fluid is released from the cylinder 8, by countersprings 16and17 In this embodiment of my invention, a check spring 18 is shown which comes into action just prior to the time the press moves under final pressure to prevent violent closing of a push button 2O and a release lever 21.V

Operation of the push button 20 permits air to enter the cylinder and actuate the piston. The valves are held in their operated position as long as desired to hold the press closed by mechanism not pertinent to this invention. To open the press, the lever 21 is operated to release the valve holding means so that the press will open up under the influenceof the countersprings 16 and 17.

The construction thus far described forms no part of this invention.

22 designates the neck band holder or clamp and 23 a cut-out in the head complemental to the clamp. There are various typesof neck band holders. `In some types of neck bands, a movable clamp member or loop 24 is yused to press the neck band against the base or block of the neck band holder.v In another type, the neck band is merely buttoned around the block. This block may also .have the usual expanding clamp. As the operation of the various types of neck band holders is well known and as the construction of a neck band holder is not pertinent to this invention, further description'is thought to be unnecessary. v

In the illustrated embodiment of my invention, the yoke lever 5 is bifurcated or double and the head 2 has ears 25 and 26 at its ends in which is xed,.as by keys 27, a shaft 28, this shaft extending lengthwise of the head along the median line thereof, and the yoke is provided with brackets 29 and 30 at the ends of the bifurcations, these brackets being loosely mounted on the shaft 28 to permit the shaft and the headto move endwise and also to have a slight compensating rocking movement. Such rocking movement of the head is desirable to permit the head to move relatively to the yoke and compensate for different thicknesses of the work overlying dierent portions of the buck so that the head presses uniformly throughout the pressing face of the buck.

The rocking or compensating movements of the head are resisted by spring connections between the brackets 29 and 30 and the head.

[There are two spring` connections 31 at `one between the nut 34 and the bracket 29 or 30,l

the spring encircling the stud above the bracket. The stud 33 is connected at its lower end by apivoted joint as a ball and socket joint 33a and is likewise connected to the bracket 29 or 30hy a similar joint 29a, the latter being provided by aspherical boss 296, Figure 7, on the seat 31a for the spring 31 or 32. The boss 295 seats in the slot 290. These pivotal or universal joints at 33a and 296 vpermit the head to shiftV laterallyv rela'- tively to the yoke lever 5. Yj

The means formoving the head laterally is here illustrated as cam members 36 and 37, the cam member`36 ybeing fixed to the shaft 28 as by a key 38 and the cam member "37 being mounted to rock about the shaft 28 and being heid from endwise movement by a spacing sleeve 39 surrounding the shaft 28 and interposed between the cam member v37 and the bracket 29. The cam members have coacting cam faces or lifts on their opposing sides. The cam member 37 is provided with a rock arm 40 and when vthis arm 40 isl rocked, the Y. cam face of the member 37 will thrust against and ride up the cam face of the member 36 thus shifting the head laterally. rThis lateral movement is against the returning action of a spring 41 interposed between the cam member 36 and the bracket 30.

The rock arm 40 is actuated during the closing ofthe press by a link 42eXtending lengthwise of the lever 5 or between vthe bi` furcations thereof, and pivoted at its'frontV end at 43 to thel arm 40 and near its rear end at 44 to a bracket 45 rising from the bearing 5a in which the pivot pin 6 of the yoke lever is mounted. The length of the linkV 42 is different, preferably less than thel length of the front arm of the yoke 5 so thatfduring the movement of the press head, the arm 40 will be rocked dueto the differential movement of the link 42 and the yoke lever 5. Preferably, the link 42 is not pivoted directly to the bracket 45 but slides endwise in a sleeve 46 which is pivoted between the bifurcations of the bracket 45, and the endwise movement of the link 442 during the elosin0r of the press is resisted by a spring 47 interposed between the rear end of the sleeve 46 and adjustable abutment or nut 48 on the rear end of the link 42. Also the linkl42 is acted on by a. spring 49 weaker than the spring 47 and acting in opposition thereto, the spring' 49 being interposed between a cross bar 50 which lconnects the bifurcations of the yoke lever 5, and shoulder 51 on the rod 42 in front of this cross bar 50. c

In order to facilitate the ironing or pressing of the shirt close up to the neck band, especially when the-neck band clamp is used embodying aloop which overhangs thekportion of the shirt adj oiningy the neck band,the head is provided with a lip 52 along the lower` side of the wall of the cut-out 23, this lip tucking under the loop 24 Vor pressingthe Leonesa vthe link 42 ini its forwardlposition so` that the arm 404 is in such position that the high points of the cam 37 rest ont-he low points of the cam 36. As the press head close'sthe pivotal connection 431d'escrilbes; a -d-itierent arc Y than does the shaft 28. y 4This difference in the arcsx described' is d-ue to the fact thatthe lever 5-and link42are different lengths and are pivoted to rotate about diierent-centers. The movement ofV the lever 5,`as the pressl closes, Will cause the link 42' to rotate the arm 40 Vandcam 37 so that'the cam 361Wil1 be thrust tothe right, in Figure, to slide the head laterally toward the neck *band-t holder.V The force With-'Which the l-ink 42 rotates the arm 401 and earn-'37 will depend on the amount of compression of the spring 47Av during the endwise movementl of' the link 42.- The nut 48 provides means for adjusting the tenslonfof the spring 47, and this spring 47 renders the means which thrust thehead laterally yieldable so that no damage willv result if the lip 52 contacts with the neck bandv holder before thev pressing jaws are together under final heavy pressure. As thehead approaches vthe buck, it moves successively into positionsA, B, CgD and E Where it is closel` to the Work on the buck and under littleor `no pressure. Dur-ing the iinal movement of. th'e'rhead from position- DI toposition-E,the 11p 5v2-moves close up to the neck bandi.
