To all lll/wm, l' may concern.'

Be it known that I, ARTHUR llannnll, a subject of the Gerllnln .Empel-or, residing at .Berlin`v lernlany, have invented new and useful lInlprovelnents in Ironing-Machines, ot' which the :following is a, specilieation.

This invention relates to an ironing lnachine, especially adapted for the handling` oli' shirts` said ironing ll'lachine hcing provided with all oseillatoij7 smoothing iron .supported hy an overhanging arm, and with an ironing iahle capahlc of heilig yraised and lowered and .lllovahly positioned in a horizontal plane helow the smoothingl iron.

The machine consists essentially of. a Alralne l, a smoothing iron 2, all ironing iahle il and driving mechanism for the iron-A ing iahle and for the smoothing iron. The machine is driven lrolll a helt pulley 4 mounted on a shaft l journaled ill ille lower part of ille nlaehille 'tl-aule.

The roller 26 is not .mounted tric 25.

directly on thetable support 21 but on a slide27 ided vertically on the inner side of the ta e support (see Fig. On the upper end of this slide isrotatably mounted a screwed rod 28 .which is provided with a hand wheel 29 and screws into a threaded opening in the table support. At the height of the hand wheel 29 a hole 30 is provided in the front wall ofthe table support- 21, through which the hand wheel can be reached. By turning the hand wheel the distance of the roller 26 from t-he top of the ironing table, and thus the maximum height of the stroke of the table during its reciprocat-ion in the vertical, can be adjusted with great accuracy.

The member 23 above mentioned has on its front wall the guideway for the table support 21, and consists as is shown in Figs. 1 and 3 in a box shaped casting open at the top and front and formed at its lower part as a bearing 31 for the hub 32 of the eccen- The eccentric drive is completely inclosed by the side walls of this projecting part of the frame and the front wall and -top of the table support 21, so that any soiling of the clothes by contact with the drive ing parts is impossible. The same care is taken with the other working parts of the machine, which up to the pedals for actuat ing the couplings are completely-inolosed within the hollow machine frame: The eccentric 25 is mounted with its hub 32 loose on the shaft 5 and can be coupled to this shaft by engagement of a coupling,mounted on the same shaft', which coupling is controlled by the pedal situated farthest to the right. The pedal 33 consists of a lever pivoted at the end on a rod 34 and 'connected b a link 35 with an arm 36 mounted on a spindle 36 journaled in the right hand side wall -of the frame projection 23. ()n the free end of this` spindle is fixed a second arm 37 inclined backward which presses from below against thc horizontal arms of two bell crank levers 33. 3S, pivoted laterallyl on the projection 23. 'llie other arms of these bell crank levers are each connected to rods 39 guided in horizontal direetion traum yersely to the shaft 5. ,lhese rods are ipro-t vided at their inner ends with headsl 4Q which arc pressed against the coupling member 42 connected to the hub 32, by. means of springs 41 (Figs. 1 and 4). The inner faces of the heads 40 are as shown in- Fig. 2 formed to fit symmetricallythe cyli1-V drie coupling member- 42, while their front faces constitute graduallyrising and then descending cam surfaces, as `shown in Figs. 1 and 4.

^ In the illustrated positionfof the parts a bolt 43 is pressed by a spring 44 into a recess 45'of the toothed wheel keyed on the shaft 5, which couples the couplingl member 42 containing the bolt 43, and thereby the eccentric 25 to the shaft 5. When this-latter rotates the inclined head 46" 'of the bolt 43 comes in contact with the nearest of the two cam surfaces 40 and is thereby lifted outof the recess 45. As soon as'the connection is released the eccentric comes to rest and the bolt 43 is held by the cam in its withdrawn position. When engagement is again to Ybe effected the pedal 33 is actuated whereupon the head 40 is withdrawn from the coupling member through the agency of the transmission rods 35, 36, 37 and bell crank lever38, and the nose of the bolt 43 released. The

bolt is then pressed by means of the springV 44 against the boss of the toothed wheel 6 until it registers with the recess 45 and on a shaft 44 journaled transversely in the.

machine frame. On this shaft is mounted an arm' 45 which is connected by a link 46 with a double armed pedal lever 4( which rocks on the rod 34. Lever 47 projects like lever from the front ofthe frame structure 23 of the machine and is here provided with a pedal 48.' A third pedall 39 is mounted between pedals 48 and 33, said third pedal being also capable of swinging on the axle 34. The lever of this pedal is one armed and is provided with a transverse rod 50 (Fig. 4), said rod projecting over the arms of the pedals 33 and 48 in front of the axle 34, so that on pressing down the middle pedal the side pedals are also de pressed and both couplings simultaneously brought into engagement.

The' machine works in the following manner. Before. the beginning of the ironing all the pedals are in the position of rest, and both couplings are disengaged, while the,` driving shaft A5 is in rotation. The ironing is not. eltected directly on the table l i i n but. on an ironing board covered with `tele is so adjusted relatively to the table Sup-v port Q1 by turning the hand wheel 29, that the, exact pressure desired is obtained when the ironing table is in its highest position.

ner over the hacking and laid upon theii'oiiing table which yis pulled outalongitsguides -for this purpose. The table with the haeking is then pushed back and the ironing can begin. lFor this purpose by depressing the pedal 33 the eoupling for the eeeei-itric is first hrouglit into engagen'ient. The table immediately rises and presses the hacking` and the shirt to he iroued againstl the bot'- tom ot' the iron il. By re'ieasing the pedal 232i and disengagiug the coupling the iron ing talile ean he kept in its highest position and by depressing the pedal vIS the drive tor thel iron brought into aetion. The .iron then performs the usual reeiproeating ironing motion with the required pressure obtained by having the Vironing table in its raised position. WhenI the front otl a dress' shirt or the like is to he ironed. the ironing motion should takeI place in one diret-tion only, away from the neek hand, while in the reverse stroke o't' the iron the latter should he out. of eontaet with the shirt front in order that ereases may he avoided. 'l`o enablethis operation to he etl'eeted, atter the ironing hoard with the shirt attached thereon has been so t'ar displaeed on the table that the, neek hand reeess ot' the iron just reaehes the ueek hand ot" the shirt when the iron is in tarthest out position,

the eoupling artuated from the pedal 33 isA engaged and the eet-entries set in continual motion so that the ironing talile performs an up and down rtwiproeation s vnehronously with the motion ot' the iron. it is `to be noted that the `eurved surlare ot the eeeentrie, as shown in Fig. l is of eonstant radius on one, halt ot its periphery so thatv tilie highest position ot' the ironingl table is retained during a haltI rotation ot' the sha t't and thus during about a t`ull stroke ot the iron. ln eonneetion therewith eonsideration should he given to the t'aet that the gear wheels t3 and T are ol au equal diametei' and vhave an equal speed ot' rotation. and.that. as the arms of the t'ork li'i are sep arated the swinging movemtait thereot' whieh eauses the oseillatory movement ot. the smoothing iron, is not. iliade use ot' to its t'ullest extent.

()n ironing' ordinary artieles. the eet-ein tritl as already explained is brought out ol' aetion alter the ironing table has attained its highest'. position and is idle during the ironing proeess, when the iron only reeipro- Cates. In pressing ironing on the other hand the iron is at restwhile the ironingr table along with the article thereon is pressed against the iron by coupling up the eeeentrie. In this manner all the diti'erent kinds, ot' ironing `an he carried ont by power in the maehine. the attendant having only to eontrol the ditferent couplings.
