Beit known that Ldosnrn H. ULLMAN', a citizen of the United States, residing at New Haven, in the. county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Ironing. Machines, of which the following is a speciication. f

My present invention Apertains .to ironing machines, the construction and advanta es4 of' which will be hereinafter set forth, re erence 'being' had to the `'annexed Ydrawings,-

wherein:

Figure 1 is a. sectional elevation .of the mafchine, the` ports being in a positionof .rest and the iron fully elevated at what may be termed the' rear `of the inward stroke;.F1g., 2v a vertical sectional view, taken on the line 2-2 of Fig. 6, the parts being in operativev position and the. iron making its. outward or forward stroke; Fig. 3 a sectional elevation oft-he upper portion of the machine, the full-line position showing the iron as having nished its 'outward stroke and raised from the board or support, and the dotted-line position the same relation or position at the end of -the inward stroke; Fig. 4 a detail sectionalV view of the clutch mechanism, taken on the line 4-4 ot Fig. 1., tbe parts being. slightly enlarged; Fig. 5 a, detail per spective view of the rocker which elevates the iron-carrying bar or rod; Fi l. |65v a transverse vertical sectional View on t eline 6--6 of Fig. 1; and Figs. 7 and 8 side and plan views. respectively, of the' clutchaeleasing and stop arm` The mainobject of the present invention is to produce an ironing machine, adapted more especially for the ironing of corsets and the like, in which the iron will be elevated from the goods at the end of each forward and rearward stroke whereby the o erator may readily shift the goods upon vt e table or support while the iron is so elevated.

A further object; of the'inventionis-to provide a mechanism which, when the operation of the machine is to be stopped, will bring the iron to restin its fully elevated position and, preferably, when it is at the end of its inward or rearward stroke.

In the drawings,'l denotes a suitable stand or bench upon which is mounted an ironing-board ortable. 2,l with which theiron 3 adapted to coact. The. iron is prefery ably Yelectrlcally heated and is connected to an actuating bar Aor rod 4 through a yoke 5, pivotally connected to tbe-outer end of the. bar, the yoke in turn being likewise connectv ed tothe iron, through the agency of a pivot-.4 I pin 6. Said bar, as. will be best.. seen upon reference to Fig. 6, passes between and is I ,s g'uided4 by the upright members 7 and 8` of a :standard or frame 9, extending upwardly I from a base plate or casting 10, secured to f the stand or bench 1. The rear end of bar/1 is pivotally connected to the upper end of av lever- 1l which latter is fulcrumed upon a shaft 12. which finds its support in gear-supi porting frame or housing 13, secured upon the floor beneath. the bench 1.. Extending :through said housing is La drive shaft 11.1., havin secured thereto axed Aclutch member .'15, a apted to coact with a sliding clutch .member 16, formed integrally with or at- .tached to ax. inion 17.. The sliding clutch member may e thrown into and out of locking engagementwith member 15 through the agency of shifter- 18 which is actuated through the agency of n lever 19. Normally this 'clutch will remain in" locked position, as g I employ a se arate clutch to bring the iron i to rest'. in its e evated position. Pinion 1,7 is in constant mesh with a ear 2O secured to l shaft 21, which likewise as ke ed to it `a pinion 22, Fig.`1, said pinion mes ing with a gear 23 secured u n a'shaft 24. Said shaft projects outwar y beyond the housing or frame 13, see Figs. @and 6, .and carries a clutch member 25, said member in the form shown being formed integrally with the said member, said openings being adapted to coact with a locking pin or bolt 27, mounted in a recess formed in a cranlo'disk 28. A spring 29, mounted inte'riorly of the pin and bearing at its outer end against a screw plug 30, secured' in the crank-disk,- urges the boltI into locking lengagement. with the clutch member. or-perforate disk 25. Bolt 27' is formed with a laterally-extending lug or linger 31 which is cut away and beveled as at 32, Fig. 7, to permit the retract-ing' member,

shaft. A series of openings 26y is formed in 1Q to the inner end of the treadle vand at its up er end is likewise connected to the. outer.

en of a clutch-releasing'andI stop arm or lever 38. Said lever is fulcrumed on a rod 38a Fig. 2, and the free end thereof stands in line with lug 31 of the boa 27, said end bein curved, see Fig. 7, and'formed with a beve Aed oninclined face 39, which terminates adjacent a stop lug 40.

' When the machine is at rest, lug 31 contacts with lug 40, the beveled end 32 having passedl into contact with'the inclinedface 39 and withdrawn the bolt 27 ,the parts then bein in the position shown in Fig. 4, the cran disk being at rest and held against any movement owing to friction of the shaft 24 and disk 25, which still continue to rotate. `This disengagement takes place when the operator removes his foot from the treadle.

l Pivotally connected to lever 38 and eX- tending upwardly therefrom is a link 41, said link havin a slot 42 formed in the upper end thereo and into which extends a pin or screw projecting outwardly from an end of a shaft 44 journaled in' theuprights 7 and 8. A V-shaped rocker, having a relatively short arm and a long arm 46 is secured to said shaft, and a sprln 47 tends to 40 .move the shaft clockwise an to thereby bring the short arm to a substantially vertical position Fig. 2.

Extending downwardly from bar 4, adjacent its inner end, is a lug or bracket 48 a second bracket having a short arm 49 and. a klonger arm 50, being likewise secured to the bar adjacent. its outer end and the iron carried thereby. 'These brackets coacting ,with the rocker serve to elevate the bar 4, 50 and consequently .the iron, in the following manner: When the operator depresses the treadle, as in Fig. 2, the clutch lever 38 is withdrawn from engagement with bolt 27,'

the parts moving from the position shown in Figs. 1 and 6 l(where they are'at rest) to the position illustrated inFig. 2. When the bolt passes into one of the openings 26,

A crank disk 28 is locked to shaft 24 and rotated therewith; consequently, lever 11 will be drawn forward and bar 4 pushed outwardly. As bar 4 moves forwardly, the rocker also swings forwardly, arm 46 moving downwardly with the bar, and the iron comin to rest uponthe goods or article 65 upon t 1e table 2. The parts are then in the armor lever'43 secured to the protrudingv positions shown in Fig. 2, the short arm 45 of the rocker Swingin upto substantially a vertical position and '1n the path of bracket 48. As b ar 4 nears the limit of its outward movement, said bracket contacts with the .70 arm 45, said arm then acting as 'a fulcrum,

see full line position, Fig. 3, and' causingthe outer end of the bar to be. elevated and the iron to be raised or lifted clear of the board.L Upon the return movement of the( bar, the rocker is drawn or swun lrearwardl by contact with the bar, an ceases to ho d the same elevated, the iron being lowered and resting on the board during its return or inward movement. The parts are so proportioned that during the movements thereof and while the iron is uponthe board thepin upon--lever or crank 43 does not contact with the upper end wall of slot 42, spring 47 at such time serving to turn the rocker forwardly and bring arm 45 into-contact with the under faceof the bar 4,I see Fig. 2. When the parts arein this position', and the ironcarrying bar 4 is' movin inwardly the forward end of arm 46 of t e rocker will lie in a plane below arm 49 land clear thesame, finally coming into contact with the longer arm 50 and being rocked rearwardly thereby. This causes the'arm 50 to lift the ironcarrying bar as said bar' reaches its limit of inward motion. Upon a reversal .of the directionV` of movement of bar 4, the rocker will swin forwardly, thereby lowering the bar and t e iron, the latter travelingI over 100' the board until it reaches its limit of outwardv movement, when it will be again elevated. This cycle of o erations continues until the operator 4relldases the .treadl. When' this is done, the clutch-releasing le- 105 ver moves up into the path of thebolt 27, and withdrawing it releases crank disk 28 from the driving shaft 24. Atl the same time, link 41 is drawn down and the end thereof engaging the pin on lever ,43, holds 1,10

the rocker against forward movement'in opposition t0 sprin 47,v thereby holding arm 46 in the path o the short arm or projection 49 of the forward bracket. Shortly after these arms contact, which they do just -before the clutch connection is broken, bar

4 will be elevated to lits Vfull extent, as shown 1n 1, the machine then coming to rest. B li ting the iron to a considerable extent w en it'reaches its limit of inward move- 120 ment and comes to rest, the table is left substantially unobstructed, and a new cover or felt may be placed `on the board vwithout fear on the part of the operator of being: burned by the iron.

It is, of course, conceivable that the connection betweenthe rocker and the clutcliwithdrawing lever ma be omitted, in which event the rocker wou d act only upon'the brackets or projections 48 and 50, the for- 13C ward long arm ofthe rocker under. such conditions being held by lthe-rocker spring out of the path 'of member 49 at all times.

Having thus described my invention, what Iclaim-is: j.'

1. In lan ironing machine, the combination of la table or supportk for the material tol be ironed; an iron; a bar carrying said iron; means for moving said bar endwise; a pivoted rocker located beneath said bar; and means carried by the bar and coacting with the rocker to cause the bar, and consequently the iron, to be elevated at the end of each Iinward and outward stroke.

2. In an ironing machine, the combination of a table or support for the mate'rial to be ironed; an iron; a bar carrying said iron; means, including a releasableclut-ch, for imparting endwi'se movement to said bar; a pivoted vrocker located beneath the bar; a projection extending downwardly from the bar adjacent that end remote from the iron and adapted to coact with one arm of the rocker to raise the bar; a pair of projections dalso extending downwardly from the bar adjacent the iron, the forward projection being longer than the other, said projections being adapted to coact with the forward arm of the rocker; a spring acting Iupon therockerv and tending to hold the rear arm thereof up toward the bar; a lever adapted to throw the clutch out of locking engagement; land connections between said lever and the rocker to hold the rocker against. the action of the spring, and to thereby bring the forward arm thereof into the path of .the short projection of the forwardv pair.

3.
