15 Claims.

Ourinvention relates to an ironing machine and, particularly, to an ironing machine embodying a plurality of forms extending radially from a single rotating member that is generally termed 5 a turreting table and 'means for automatically moving the respective forms into and out of iron,- ing position.

, Heretofore, ironing machines of the above have embodied a centrallylocatedrotatingmember and a plurality of forms extending radially or, diametrically outwardly therefrom but these devices have embodiedno means for automatically moving the individual forinsinto and out.

of ironing position, such movement or 'rackin of the forms being done by hand.

One object of our, invention is ironing machine of the above type embodying operatomoperated means for; controlling the movement, of the forms into ironing i;relation with an, ironing member after they have been moved intoalignment therewith and automati cally operating means controlled, by the actuating mechanism'for moving the forms into and out of ironing engagement with the ironing member for intermittently. moving the respective forms disposed about the central rotating means into alignment with the ironing member.

Various other objects and advantageous features of our, invention will be seen in the following description and one embodiment thereof may be seen in the accompanying drawings wherein similar charactersof reference designate corresponding parts, and wherein;

Figure 1' is a plan view of an ironing machine embodying our invention; Figure, 2 is a fragmentary view, partly in-elevation and partly in section, showing the latching means for the tur-' reting table and the main valve operating mech-- anism forming a part of our device; Figure 3,

Fig. 9 is an elevational viewof an ironing machine embodying our invention. e e

Referring to the drawings, wehave shown one embodiment of our invention as comprising ironing machine having a base I and a heated ironing member 2 mounted" upon a support 3, the heated ironing member having the customary steam inlet 4, The ironing machine also consists of a plurality of forms or bedsji, there being two forms or beds in this instance each provided with a yoke pressing member 5'. One of these pressing,

members is shown disposed beneath'the ironing member 2 :and the other in a position to receive thegoods tob'e ironed and thepre'ssing members -being mounted upon orjoined to a rotating means or turreting tablet by means of radially extending arms -'I.' as shown by the dotted lines in Figure l, one'of the beds 5 is being moved out of alignment with the ironing member 2and the other form which is diametrically "disposed relative to the first form isbeing moved into alignment with the 'ironin'g member due to rotation of the turreting table 6 on which the beds aresupported. The turreting tableis disposed on a vertically extending pedestal 8,

Practically the entire mechanism for moving the beds 5 into alignment with the ironing'mem ber 2 is supported on the base I, and the ironingmember 2 is supportedby uprights 9 at 0p- 7 positejsides of the base andin such position that the beds 5 will clear both i 01 theuprights when moving into-or out of alignment with the "heated'ironing" member. In thisln'stance, the turreting table 6 is not on a' straight line between the uprights "9 butiis disposed laterally thereof.. h I a As shown in Figure 3, the means for rotating the turreting table 8 and thereby moving the respective forms 5 into or out of-alignment with the ironing member 2 consists of a cylinder III having a piston ll therein, the cylinder being supported on the base' lby.-a bracket l2; An-

exhaust conduit ll leads from the inside of the cylinder below the under surface of the piston II toa conduit I through which air between theunder surface of the piston and the cone- 7 sponding surface of the cylinder will exhaust to the atmosphere when the piston l is being moved inwardly; A conduit l5 leads to'the inside of the cylinder Ill above the piston ll whereby fluid pressuremay be delivered to and exhausted from the space between the upper surface of the piston and the corresponding surface of the cylinder to move the piston intached to the extreme outer end thereof which all! Fisguided upon guiderods l3 and normally held in its outermost position, as shown in Figure 5, wherein the piston II is at the outermost end of the' cylinder [0, by means of compression springs l3 also disposed on the guide rods l8 and adjustable as to .tension by means of adjusting nuts 29 and by means of which the speed of outward travel of the head andpiston may be regulated or controlled. With this construction, the piston II is normally moved inwardly by fluid pressure entering the cylinder through the conduit l5 whereby the springs 20 are compressedand is moved outwardly by theaction of the compressed springs when the pressure above the 'piston'is released. r

The member or head I! has 'a link'2l attached thereto, the opposite endof the link being pivotally secured to one end of an arm 22 that is pivoted as at 23 and forms an operating arm for rotating the turreting table 6. Trigger mechanism consisting of a trigger 24 that is normally held inits outermost position wherein it engages a pin 25-on each ofthe form supports by means of a spring v25 and is limited in its outward movement by' a flat surface 21 which engages a flat surface on they arm 22 is carried by the opposite end of the arm from'that end to which the link 2| is attached. "Movement of the end of the. arm 22 to which the link. 2| is attached is controlledby an adjustable stop. 28 whereby rotation of the arm 22 about its pivot mayberegulated. I,

In the operation of this part of theapparatus, when the bed 5 whichis inalignment' with'the ironing member 2 is out of ironing engagement with the member, the turret operating mechanisni just described 'is'in the dot dash line position shown in Figure 3, wherein'the trigger 24 is out of engagement with the pin 25. However, when the aligned form and ironing member are in ironing eng'agement, fluid pressure flows into the cylinder In above the piston .l I by. way of the conduit l5 as will be hereinafter described to move the piston inwardly compressing or winding up the springsv l9 and moving the arm 22 to the full lineposition shown in Figure 3 wherein the'trigger engages the pin 25, such trigger passing the pin 25 as the arm is rotated about its pivot in this direction due to its resiliency through its pivotal mounting and the spring 26. 3

Then, upon release of pressure from the outer surface of the piston II which takes place when the aligned form 5 is moved out of engagement with theironing member 2, the springs l9 will move the head I! and piston H outwardly with a quick action and rotate the arm 22 about its pivot, the trigger 24 through its engagement with the pin 25 of the form that is in alignment with the ironing member moving theform 5 out of alignment with the ironing. member and the other form 5 into alignment therewith by retating the turreting table 6, on the pedestal 8. As shown in Figure 2, a latching means consisting of alatch member 29 that is held inits uppermost position by means of springs 39 and a latch pin 3| is provided for stopping the rotation of the turreting table 6 when one form 5 is in alignment with the ironing member 2 and holding that form in such aligned position, as well as holding the other form in loading position.

As shown in Figure 8, a cylinder and piston construction is provided immediately beneath the heated ironing member 2 in such position that the uppermost end 32 of a piston rod 33 that forms a part of a piston 34 in a cylinder 35 will contact with the under part of the shaft or rod 18 which is mounted immediately beneath the ironing forms 5, and'move the form upward into engagement with the heated ironing member for the ironing action. The extending arms 1 of turreting table 6 are provided with a cylindrical sleeve 19 which provides a bearing for shaft or rod 18* of the ironing form, during its upward and downward movement. A guide rod rigidly attached to ironing form 5 is provided and is disposed to move upward and downward through a sleeve provided in arm 8 I thus always maintaining the ironing form in correct alignment with the ironing member.

As shown in Figure 5 fluid pressure for raising the piston 34 to move the'aligned form 5 upwardly flows through a supply pipe 36, through a conduit 31, past a'needle valve 38 for controlling'the rate of flow of the fluid pressure, past 'a valve '39 which is operable by a foot treadle 40,

and through'a j conduit 4| between'the under surface of the piston 34 and the corresponding surface of the cylinder 35, the air or pressure between the uppersurface of the, piston 34 and the corresponding surface ofthe cylinder 35 exhausting through a conduit 42 and exhaust conduit I4. r I

Reversely, the piston 34 ismoved downwardly by the weight of the form 5 resting thereon, the fluid pressure between the under surface of the piston 34 and the corresponding surface of the piston 35 exhausting through the conduit 4i and ment thereof, the arrangement is such that when the inlet valve 39 is opened the exhaust valve 45 will be simultaneously closed byaction of a spring 43' the operation of the single'foot treadle 40. Likewise, the arrangement is such that when it is desired tolower the form outof ironing engagement with the heated ironing member 2, operation of the'foot treadle v44 to cause opening of the D0rt 43 by movement of the valve 45 will permit the valve39 to be closed by action lever arm 41, the other end of the lever arm carrying a roller 48 adapted to bear against the face of a cam element 49 thatis disposed on one end of a lever arm 50 rigidly mounted on 'a shaft 5|. The cam 49 is of such shape that the lever arm 41 is turned so that the valve 39 is normally in closed position and the valve is moved to open position by means of the foot treadle 40 which has an extending portion thereof connected to one free end of the leverarm by means of a link 52. After once being moved to open position, the valve 39 will be maintained therein by the roller 48 engaging a raised portion 53 on the cam. 7

In alike manner, the exhaust valve 45 disposed in ahousing 45' andwhich is normally in closed position also, has its stem connected to one end of a lever arm 54 whose other free end carries'a roller engaging a cam 55 that is oppositely disposed as regards the cam 49 and is rigidly. mounted on the same shaft 5|. -Such valve is movedto open position against the resistance of the spring 43' bydepressing a foot'treadle 44 which has a portion thereof connected to a crank arm 51 by means of a link58. Another part of the crank arm 51 is, in turn, connected -,to the free end of the lever arm 59 which carries the cam 55 by means of a link 50. With this construction, depression of the foot treadle 44. will move the cam 55 upwardly,- the cam being so shaped as to move'the lever arm 54 about its pivot in a direction to open the valve 45.- With. the cams" and 55 oppositely disposed and rigidly mounted on the same shaft, it will be apparent that movement of one cam to open one valve will operate the other cam to close thevalve controlled thereby or vice versa.

the turreting table and forms will be released and the turreting table maybe rotated inthe manner hereinafter described on downward movement of the piston 34 and ,downwardmovement of the forms under their own weight.

Means have been provided for causing rotation of the turreting table 5 immediately on the form 5 which has been in ironing'engagement with the ironing member 2 reaching its lowermost position; As shown in Figures} and 4, an auxiliary valve 5 I. controlling the flow of fluid pressure to the outer surface of the piston l whereby the piston is moved inwardly and thetrigger mechanism-set as hereinbefore. described,.is operablelby the upward and downward movement .of the form 5 which is in alignment with the ironing member 2 through a system of levers which each form engages as 'it moves into aligned position with the pressing member. V

The means for operating the auxiliary valve 5| consists of a lever 52 pivoted to'the frame as at 53 and having a slot'and pin connection with another lever 54 which is pivotally mounted as at 55 to an upright 55 on another part of the frame whereby the yoke may move out of engagement with the stud 10 as the form completes its cycle of movement from aligi'iment with thehead to the loading and unloading station. Also, the lever 54 is connected to the upper end of the sliding portion 12 of the auxiliary "valve 5| by means of a link 13. r f

In the operation ofthispart of the apparatus, which is a means for automatically causing rota tion of the turreting table 5 as each form 5 reaches -its lowermost position after ironing engagement with the ironing member 2, as each form .5 moves into alignment with the ironing member 2 due to rotation of the turreting table 5, the stud or before described, the yoke member will move upwardly with the form and in doing so will engage the stud or pin." on the lever 52' and the levers '52 and 54 will be moved ,to the dash and dotline position. shown in Figure 4 during which movement the sliding portion 12 of the auxiliary; I I

valve 5| will be raised. In. a reverse manner;

when the aligned form 5 is permitted to lower un-:

der 'itsown weight due to the operation of the foot treadle, 44- and release of pressure from be neath the piston 34 as hereinbefore described;

the levers 52-and 54:.will be-moved tothe full line a position shown in Figui'e*-=.yvherein the sliding portion 12 of the auxiliary valve.. 5| will be moved downwardly'to the position shownin' Figure 5, the weight 59 at theifree end of. the lever 52 being provided to assure the return of the ley'ers52 and 54 to their original starting position and the downward movement or closure ofthe sliding portion. 12 of the auxiliary valve 5|.

. Upward movement of the sliding portion 12 of the valve 5| will permit fluid under pressure to: I flow from the supply pipe 35 past the cut away portion-"l1 of the sliding; member and through the conduit l5 into the cylinder [5 between the side of the piston exhausting'through the conduit l3 and exhaust conduit '|4. Thus, the setting of the trigger mechanism and compression of the springs I9 is automatically brought about by the upward movement of the aligned form 5 into ironing engagement :with the ironing member 2.

/ After the ironing operation is completed, the form 5 is lowered ashereinbefore described, and the auxiliary valvev operating levers returned to their normal position wherein the sliding member 12 is moved. downwardly to the position shown in Figure 5 or tocloscd position, the fluid pressure that holds the piston H in such position that the .springs I! are compressed will exhaust thioughthe conduit I 5, through a port [4 inthe stem of the sliding member 12 and into thehollow, interior thereof, through a conduit 15, andinto the exhaust conduit ,|4 whereby the com-L- 65" pressed springs |9 may act to rotate theturreting table 5 and reverse the position of the diametrically disposed forms 5 as hereinbefore de-v scribed. The cycle Justdescribed isfrepeatedat the movement Ofeach individual form into erated means which includes the foot treadles for operating the main valve for controlling the movement of the bed that is aligned with'the ironing head into and out of ironing relation with. the head and haveprovided means operating automatically .which includes the slidevalve SI for moving the'beds alternately into and out of ironing alignment-with the ironing head as well as a latching means operable by the operator operated means which releases an ironing bed from engagement with the ironing head for holding the beds in their aligned position.
