LAUNDRY PRESSING-MACHINE.

1,010,696, I Specification of Letters Patent. i

T o 'all whom t coment;

i l- Be it known-that I, .CARLOS A. SMITH, a

citizen of .the United States of America., and resident of Bellaire., county o-f Belmont, and State :of Ohio, V@have invented certain new andkuseful Improvements in Laundry Pressing-Machines, Lof which .the following; .is a specification. 7 s

rflhis invention rela-testo improvements in Iironing machines, and more particularly --to -an automatic machine of that' class wherein the article -to lbe acted `upon is'subjected to the pressure olf a heated plate. x f

'The primary .object of 'fthe invention is to provide a machine which is particularly adapted for ironing shirts and which shall mechanically and automatically subject a shirt mounted thereon .to an ironing pressure. v

A.' further object is to provide in a machine of the character mentioned a construction wherein a pair vor ironing plates are employed and wherein the movement of one plate to operative ,position-.actuales the other` plate to move from such position. And a still Nfurther Objectis to simplify and structurally improve `that class of laundrying machines known as fla-t ironing machines.v

With these and lother objects in View, .the invention finally consists in the particular construction, arrangement and combination of parts which will hereinafter be fully ldescribed, reference being hadto the accomL lpanying drawings, 'forming a ypart -ofthis specification, in -which- Figure 1 is atop plan view ofthe invenf tion; Fig. 2 is a vfront elevation of the same;

. Fig. 3 is an end elevation ofthe same; Fig.

4C is a horizontal section on the line F4, Fig. 2; Fig.- 5 is a partial longitudinal section, -showing the elevating fmeans; Fig. 6 is, 'a partial central .cross sectionalview,"parts J of the inechanism -being shown ,in-lelevation; Fig. 7 is an .elevation of :the :plate locking ,mechanism illustrated i-n Figs. 3 and 6,

showing the .same partl in broken section and vparts thereof -in di ere'nt Epositions assumed in the operation thereof; F ig. 8 is a View similar :to Fig. 7, showing parts of the/ plate-locking mechanism ina still different position; Fig. 9 is a=detail lview of a part of the belt-shifting mechanism; Fig. --10 is an enlarged vcross section Aofthe slide-.block .and the arm inwhich said' slide-block is mounted.

Referring :to-said drawings, .in which like of each slot .9 adjacent to the lower end of easing 8 is a slotted tubular member .14

designating .characters distinguish likeparts y throughout v.the several views--l and 2 indi- `cate two supporting pillars formed on 'a 4common base 3 and having respectively xed .upright istandardsd and 5 upon. the upper ends of which are mounted the opposite endsof a crosshead 6. Supported by saidcrosshead on its under side in a central position is .anironing plate 7 which is maintained at a' substantially constant high temperature inv anya-ppropriate manner, 'asf by passing therethrough steaan lor heated air.. v

Formed' on the .base ,3 midway between and in alinement with the pillars 1 and 2 is an upright hollow casing 8 providedat opposite sides 'for .a portion of .its length with slotsk 9, also Viii alinement with said pillars. Having its ends Xed in bosses 10 formed on said casing and extending' transversely thelatter is a shaft 11 upon which is mounted an anti-friction roller 12.v A wedge 13 I having a straight lower face andan inclined upper'faceis .projected horizontally through the slots 9 and rests upon vsaid rollers 12. Said wedge isQarranged to,I be movable longitudinally through the slots of the casing for a purpose which will presently .be eX-- plained. Vertically movable within Vsaid which has a' reduced eXteriorly-threadedaupper end 15 .upon whichis carried an /adjustf able collar 16. With its -ends fixed in opposite sides of said tubular member Maso as to lie transversely and centrally ofthe to .rest upon the upper face o f said wedge 113 and to thus support said tubular member and the superposed par-ts.

Extended .longltudlnally` through .the wedge 13 is.a.bore ,19 through which extends a revoluble shaft 20 whose opposite ends ,are journaled inappropriate bearings lfand 2 infthe pillars' 1 and 2 :and which carries upon l100 one end two loose .pulleys 2l and 2 2 with an interposed vfixed pulley 23. The bore 19 is threaded a portion of the way an has inl operative .engagement with the threads thereof the .threaded 1portion -24- of .the shaft 105` 20 whereby, 'when said shaft is rotated, said wed e is-moved forward or backward, acv

cording to -the direction .of movement 0f said shaft. As is obvious, when-thawedge is moved forward, the tubular member 14, 110

toY

9 0 same isa .shaft- 17 .upon which .is rotatably mounted an anti-friction .roller 18 adapted supported on the inclined face thereof by means of the roller 18, is elevated, and vice versa. l

Rotatably mounted on each of the standards 4 and 5 is a pair of separated collars 25 and 26 which are connected by an archbrace 27, as shown in Fig. 3. Carried upon or formed integral with the ends of the parallel outstanding arms 28'and 29 which are carried by or formed integral with said collars 25 and 26 are collars 30 and 3l which are connected at the-side opposite to. said arms by a web 32. Said collars 30 and 31 loosely embrace a tubular plunger 33 upon the top of which is carried an ironing table 34 which is adapted lto be reciprocated with said plunger into and out of pressure-applying relationwith ironing plate 7, in a manner whichwill herein be explained. Said plunger 33 has an annular iange 35 which,

when said plunger is at rest, in its lowered positon, rests upon a bearing ring 36 encircling said plunger and mounted upon ball-bearings 37 interposed between it and the top of collar 30. Said collar 25 carries thereon and preferably integral therewith a horizontal crank-arm 38 which stands at substantially an angle of 135 to `said Aarm 28. Connecting the free ends of the opposite crank-arms 38 1s a pitman 39, as shown.

Rigidlyk mounted on each of the stand-,-

ards 4 and '5 intermediate the collars 25 and 26 is a collar 40 having an integral crankarm 41 to the free end of which is pivotally connected one end of a rodi or pitman 42 Whose opposite end is pivotally connected to a crank-arm 43 carried by said plunger 33 at a point intermediate the embracing collars-30 and 31.

As is obvious, when one of the plungers 33 bearing an ironing table 34 is moved or swung from an outwardly extended position into superposed relation to the' adjustable collary 16 with the table beneath the ironing plate 7, the other plunger is moved or swung outward, through the intermediate mechanism just described, into the position indicated in Figs. 1, 2, 3, 4 and 5. In other words, the movement of one plunger for bringing one ironing table into operative position beneath the ironing plate moves the other table from the last mentioned position to an outwardly extended position.

The mechanism employed for shifting the belts for operating rthe plungers and for locking the ironing tables in pressure applying relation to the ironing plate Will now be described.

Fixed upon the rear side of the casing 8 is a bracket 44 upon4 one side of which is rigidly mounted a 'plate 45 having outwardly extended parallel arms 45vvhich` are in supporting engagement with, or have formed integral therewith, a sleeve-bearing 46 in which is rotatably held a shaft 47.

Fixed upon one end of said shaft is a crankarm 48 to which is pivotally connected a rocker 49 in whichv is adjustably `held one Fixed upon the end of the shaft 47 opposite that which bears the crank-arm 48 is an oppositely-disposed crank-arm 57 the free end of which is pivotally connected to a collar 58 which is rigidly borne by the movable sleeve 59 of an upright plunger rod 60 which operates in a pair of vertically alined bores 61 and 62, said rod 60 having an enlarged lower end 63 which is pivotally f mounted upon one end of a lever or treadle 64. Said lever or treadle is pivotally mounted intermediate its ends, as at 65, and has a foot-plate 66 on its opposite end. j

Fixed upon each plunger 33 intermediate the collars 30 and 31 is an outstanding arm 67 the outer end of which is provided With an upwardly-inclined bevel 68 which, when the plunger is moved to a position underlying the ironing plate, rests upon an inclined seat 69 providedvu'pon the bracket 44, as shown at the right of Fig. 3. A dove-tail channel or mortise is provided in the aipper face of said arm 67, and slidably mounted insaid channel is a slide-block70 having an integral vertically-bored hub 71 formed,

upon its outer end. Seated in the bore of 'said hub and normaly held depressed with its lower end -projected therefrom is a vertically movable locking spindle 72 whose said lower end is adapted to seat in the upper end of the bore 61 in the bracket 44 for locking the plunger 33 in position beneath the ironing plate 7. Springs 73 connected to the projecting ends of a cross-pin 74 carried `by the upper end of said spindle 72 serve to normally hold the latter depressed in locking position. The slide-block 70 has an outwardly directed pin 75 movably held in slots 76 provided in the sides of the arm 67 for limiting its range of sliding movement. A coil spring 77 interposed between the inner end of said block and the foot 78 of said arm normally holds said block forced outward to the limit of its outward movement. Slidably mounted in supporting posts 79 and 80 carried by said bracket 44 in the rear of said slide-block 70 and in alineinent therewith is a rod-81. Mounted upon said rod 81 between a transversely directed pin 8,2 carried thereby and a slidable collar 83, also carried thereby, is a rcoil spring 84. A yoke 85 fixed upon a transversb shaft 86 journaled in the lupper-ends of posts 87 carried by the bracket A44 on opposite sides of the path of movement of the rod -8-1, has fits arms pivotally connected to v'oppositely disposed tru'nnions-carried by said collar .83, so that movement of the shaft `86 will result in the collar beingmoved with frelation to the spring84. Fixed upon the opposite ends of, V,said-shaft 861are crank-arms 88 to which are pivotally connected the upper ends of rods 89 whose lower ends are pivoted to the .end of the treadle 64'.

Now, assuming that all parts] of the mechanism hereinbetore described have just been .moved to the'position shown in Figs. 2 Iand 3, in which one of the ironing tables 34 isv shown inlunderlying relation to the ironing v plate 7, but not elevated in pressing engage- .i

ment therewith, and the other Vvtable is shown in extended position, this movement has caused the .locking-spindle 7 2' to seat in -tlie .bore 61 and :to depress 'the-sleeve 59 bearing position, as shown in Fig. 3, andthe crankarrh 48 4to move rearwardly, gthus producing the shifting of the belts 9.0 and 91 outward to bring straight belt 90 into'operative relation 'to xed pulley 23.

20 just begining to rotateforward for forcing wedge 13 inward to elevate vthe ironing' table 34 :into pressure applying relation tol The elevating .movei y ment continuesy until the wedge 13 hasreached -a point 'where the bracket farm .56?

the ironing plate 7.

carried -by Athe latter engages .a fixed collar lower the said "ironing table lfor changing the relative working positions of the tables, the operator depresses the front end of the treadle 64, thus elevating the rear end thereof;

of thet-wo ironing tables. As the tables are reversed, one of the arms 67, with slide-block 70 and locking-spindle 72, `is carried away from the bracket 44, andthe other .-arm, with agolo'eee collar 58; Aand lto consequently lower the. crank-arm 57 below its normal horizon-tal Consequently, Figs. 2 and 3 illustrate the revoluble .shaft v As is obvious, this movement `of the' treadle will elevate the plunger-rod so? l that the locking-spindle will be raised against A the tension of the springs -73 out-of its in- I j terlocking position, substantially as shown in Fig. @whereupon the parts are in position to admit of a reversal of the positionsA slide-block and locking-spindle,moves toward said bracket.' In approaching said bracketA the lower end of the ylocking-spindle 72 may engage :the inclined face 69 of said bracket, in which .case it is .gradually raised' against the tension-of, spring 7 3as it moves or rides forward along said incline. Reach- :ing a yposition .in register with bore '61 the spindle is -actuated by spring 73 to drop 'into said'bore, as shown in Fig. 3. At the time .that the treadle is first v`depressed, the rods 89 are elevated, reducing, 'through the intermediate mechanism 'hereinbefore described, a forward movement of the rod v8l which brings the :front end of the latter into engagement with vthe lhub 7-1, .as shown in Fig. v6. Further elevation olf said rod 89 results :in the coil spring 84 being compressed,

as shown in Fig. 7, and, upon the locking spi-ndle 7 2 being withdrawn :from its locking posit-ion, said spring 84 kicks the slide-block v70 inward :against the tension of lthe spring 77, to substantially' the position shown `1n Fig; 8, allowing 'the sleeve 59,fbearing the cellar 558 to which :the crank-arm 57 is pivoted, to'mo've upward, as is also shown in Fig. 8, which 'ilast 4movement eiects the shifting of the belts and 91. inward from the position shown` v in Fig. 5 :t-opositions wherein :the former rides upon the inner edge of loose .pulley @Land the latter upon .the vizred pull-ey '23. The belt 91 being a crossed belt, a reverse movement is imparted 'to the revoluble shaft :20 which eiects the `withdrawal Aof fthe wedge 13, and conse- `quently ithe lowering of the plunger 33. When the wedge 13 has been sufficiently withdrawn, the operator lremoves-the toot pressure from the Itreadle, whereupon the weight of the parts automatically eiects the return moiv ement of the rod 50 and a conse- .ich

.quent return shiftingofthe-belts so that the :fixed pulley is =again released.

.Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, -is-' f i 1. The combi-nation with an ironing plate,
