This invention relates to garment pressing and laundry ironing machines.

An object of the invention is to produce a garment press or ironing machine having new and improved operating mechanism and designed especially to take up little space and at the ame time afford awide opening jaw motion to produce extended visibility of the work and pressing jaws.

A further object of the invention is to produce an operating mechanism for laundry ironing and garment pressing machines especially adapted to cufl and neck band or other work in laundries and the like. \Vhile I have chosen a V-type cuff and neck band shirt jaw machine. such as ordinarily used for ironing cuffs and neck bands, the mechanism of this invention is also adapted to machines having large size flat press jaws both for ordinary tailors pressing work, for seam flattening and pressingoperations, and large fiat piece laundry work. The inventionalso embodies improvements in operator-actuated opening and closing means to move the jaws into and out of pressing alignment and power or motor means operating automatically to produce great pressure on the work.

The accompanying drawings illustrate one' practical form of the invention but it is apparent that certain changes may be made in construction and operation without departing from the scope of the invention.

Figure 1 shows a side view of the garment press in closed position just prior to inception of jaw movement to compress tightly on the work; and Figure 2 shows a front view with the jaws in the same position.

Figure 3 illustrates a side elevation of the machine with the pressing jaws or members in open position; and Figure 4 is a partial front elevation and section as developed along the section line 41 of Figure 1.

Referring further to the drawing for a more detailed description of the invention, there is shown a press frame pedestal supporting the operating mechanism; and the frame may carry a table 11 provided with a central slot 12 in which a buck jaw standard or push rod 13 may oscillate or swing back and forth. Cooperating pressing members or jaws such as a buck 14 and head 15' spectively anchored 011 the upper extremity of standards 13 and 14. The spaced outer head standards 14 are placed outside the table 11 while the single inside buck standard pro ects through the table.

The buck and head jaws 14 and 15' means such as by are repressing members or are heated by any suitable steam or electricity, but the heating means is omitted for clearness in illustration and description. The adjacent working faces of the two jaws may be given any suitable form or shape.

The lower ends of the swinging head standards 14 are anchored at their lower ends .to a shaft 15 which is journaled in the pedestal frame 10. Both lower ends of the outer standards 14 are pinned or otherwise secured to the shaft 15 so that a pedal 16, which is likewise plnned and anchored to the shaft 15, may be depressed by an operator to rotate the shaft 15 thereby swinging the head 15 forwardly to a vertical position such as shown in Figure 1. An extension arm 17 is cast integrally with the closing pedal 16 and projects rearwardly from the shaft 15. The rear end of the arm 17 is provided with an adjustment screw and nut 23 the purpose of which is to auto matically open and close a steam throttle valve employed to stop and start the high pressure motor means hereinafter described. The pedal 16 or any suitable prime-mover means is used to swing the uprights 13 and 14 for opening and closing the press jaws.

An opemng pedal or kick-off pedal 18 is anchored to a shaft 19 which is journaled in the frame and a collar 20 may be anchored to the end of the shaft 19 to hold the kicksofi' pedal or more particularly a lug 21 in proper position directly underneath the aforesaid closing pedal 16. The upwardly projecting lug 21 rests in contact with the underneath edge of the pedal 16. The weight of the pedal 18 causes the shaft 19, to which the lug 21 is attached. to hold said lug against the pedal 16. Therefore, when the standards 14 are-standing vertically with the closing pedal 16 in downwardly limited position. it follows that the kick-off pedal 18 is standing up in position ready to be thrust down by the foot of the operator in order that the standards 14 and head 15 be tilted rearwardly thereby opening the press. The shaft 19 carries a hub 24 fixed thereon, the purpose of which will be hereinafter described, and an arm 22 is integral with the hub.

The centrally disposed standard or pressure producing upright 13 is adapted to reciprocate through a short distance to produce high pressure jaw clamping action whereas the head standards 14 do not reciprocate since they are pivotally connected directly to the shaft 15. Furthermore, the buck standard 13, in addition to this reciprocating motion, likewise oscillates back and forth in a manner quite similar to the back and forth movement of the standards 14. The two press jaws 14 and 15' therefore move along a horizontal line to and from each other, said motion occurring simultaneously. Since both jaws move laterally towards each other and apart, it follows that each jaw moves through a very short angular distance.

A swinging yoke or U-shaped member 25 is pivotally mounted on hearing pins 26 which are being anchored in the pedestal frame 10. The upper end of the yoke or lever 25 is provided with an integral guide sleeve 27 in which the buck standard 13 is slidably confined. The lower ends of the yoke 25 are movably carried outside the pedestal frame 10 and a pin 28 is rigidly anchored to each lower yoke end. Each pin is confined for free movement in a slot 29 made in each standard 14. The slots 29 permit free oscillating motion to be executed as between the standards 14 and the downwardly extending yoke ends 25, and so it follows that the yoke 25 pivots on the bearings 26 while the long standards 14 pivot on a point near the bottom of the frame and the two members 14 and 25 swing freely in connected relation. It is now observed that, by depressing the closing pedal 16, the rotary motion of the shaft 15 is transmitted to the central standard 13 and the two outer spaced standards 14; and the operation is such that one downward short stroke of the pedal 16 swings the head and buck together into pressing alignment since slightclearance is always present between the jaws when the head and buck standards are in motion.

A motor housing 32 is anchored between the upright frame pieces 10. A fixed lower cap 33 closes one end of the motor housing, and the lower extremity of an extensible and contractible bellows 34 is set and anchored pressure-tight to the inner wall of said cap. The cap 33 connects with a steam or air pressure passage 35 by which fluid pressure is c nveyed to the motor means. The upper end of the bellows 34 is closed pressure-tight with a diaphragm head 36 which head carries an integral push rod 37 slidably projecting through the upper end of the housing 32.

The upper end of'the motor push rod 37 supports the weight of the buck standard 13 and jaw 14 mounted thereon; and it is observed that, when the diaphragm 34 expands due to fluid pressure admitted thereto, the push rod 37 moves upwardly with great force carrying the standard 13 with it and jamming the buck 14 tightly against the pressing surface of the head 15'.

An important feature of this high power motor construction is that the movement of the diaphragm is extremely limited. Usually the movement of about one-sixteenth to one-fourth of an inch at most is of the greatest sufficiency as far as reciprocating or expanding the diaphragm 3 1 is concerned.

This extremely short' reciprocatory motion imparted by the motor to the press jaw buck 14' is an improved feature in the operation of the press obtained thru the agency of the improved motor means for the. reason that, since the diaphragm expands and contracts through a limited movement, the life thereof is practically unlimited because of the fact that the expansion and contraction takes place well within the flexible limits of the diaphragm. Such efficiency and long life operation is quite impossible in motors of the piston and cylinder type for the reason that relatively movable parts are there employed wherein wear occurs permitting steam and water leaks. No steam and water leaks may occur in the diaphragm motor device because relatively movable parts are not present; and furthermore the water of condensation which results from steam entering and leaving the diaphragm drains back through the passage 35 and is discharged out through an exhaust and thus no leakage occurs in this machine.

Control means are necessarily employed to stop and start the operation of the motor means which is to say a throttle valve 38 is included in a steam feed supply pipe 39 which leads to the passage 35. The throttle valve 38 may be of any approved type and in this instance it is provided with a valve stem 40 which is engaged by the adjustable screw 23 carried on the rear end of the throttle operating arm 17. \Vhen the operator depresses the pedal 16, it follows that the press jaws 14 and 15' move into vertical pressing alignment; and at the same time. the arm 17 rises to thrustv its screw head 23 against the valve stem 40 which opens the throttle valve 38 and admits steam or air pressure from the feed pipe 39 into the motor which causes it to expand and thrust upwardly against the buck jaw 14' in a manner already described.

The machine stands under pressure as long loo as the throttle valve 38 is held open by the control arm 17. When the pressing operation is completed and the work between the jaws is finished. the operator depresses the a pedal 16 which tilts kick-off pedal 18 which tilts the arm 22 up wardly. Through the agency of a link 41, an exhaust valve arm 42 is pivoted upwardly to open an exhaust valve 43 included in the passage 35 and in an exhaust pipe line 44; and so it follows that the fluid pressure expanding the bellows 34 discharges outwardly through the exhaust pipe 44. S multaneously therewith, the downward pressure imposed by the operator on the pedal 18 causes the lug 21 to push upwardly on the apart the pressing jaws of pressing alignment other to open the press visibility of the press 14' and 15' and out and away from each and afford extended and completed work.

A feature of this machine is the double motion or acting jaws and the double rectilinear opening and closing movement which is accomplished without wide angular pivoted jaw movement so common and so dangerous in operation as characterizes presses now in use. It is noted that the parting acu tion of the jaws is accomplished with slight clearance, so much so that ones fingers or hands cannot accidently get in between the jaw pressing surfaces.

Furthermore, no counterbalance weight or springs are employed in this press construction. The weight of one of the jaws, in this instance the buck 14, is suflicient to produce jaw separation to remove compression, and theweight of the jaws are placed high above the fulcrum centers which produces an inverted pendulum action causing the machine to be sensitive in opening and closing mo tion, which is to say the standards 13 and 14 oscillate at-the expense of very slight eflort.

An advantage of the diaphragm motor means over piston and cylinder type motor means is distinctively marked in that no inside moving parts are present to cause leakages, no stufiing box is employed and the water of condensation which accumulates in side the motor means drains off through the exhaust valve and pipe lines and therefore the press is a cleaner working machine than power presses now in general use.
