Application filed November 16, 1925.. Serial 1T0."69,235.

This invention relates to presses and more particularly to improvements in press operatingmechanism useful for example in garment presses, ironing and laundry presses and the like.

An object of the invention is to produce an improved pressin machine which is comparatively small an compact in structural 1 arrangement to the end that a weight balanc- 10 ing mechanism may be mounted on the mside of the press frame thus improving the appearance of the pressing machine and requiring less floor space therefor. p

A further object of the invention is to I produce a' pressing machine having improved press operating mechanism comprising relatively few parts so as to reduce the cost of manufacture and simplify assembly operations. The accompanying drawing illustrates an embodiment of the invention with the press jaws closed. The press is shown open in dotted lined position, partially diagrammatic '2 tration.

, Referring now more particularly tothe diagram or drawing f this to simplify the illusforming ,a part 0 disclosure, there is shown a press frame carrying the usual work table 11 which holds 30. the work on the table to prevent it from accidentally getting into the operating mechanism. The press frame supports a stationary buck 12 a ainst which a movable head 13 raises an lowers. The pressing members or jaws 12 and 13 open up, as by lifting the head jaw 13 to receive the work which is spread uponthe buck 12 and the mechanism for raising and lowering the head 13 is improvedin many respects over 0 pressing machines now in use.

A press lever comprises a long curved lever 15 pivoted at 16 on the frame 10 and the lever 15 moreparticularly consists of a lower vertical arm 17 and a forward horizontal arm 18 attached by a suitable spring compensating means 19, to the head 13. The press lever 15 is preferably shaped to extend it vertically downwardly within the press frame 10 when the press is closed and when the press is open the. lower arm 17 of the table 11 as indicated in dotte head-operatin handleismade on the for-j the illustration being the press lever moves forwardl towards lines. A

ward end of t e lever arm 18 for the purpose of facilitating .closure of the ress in case the operator wishes to draw t e head down by hand.

A vertically mounted swing arm 20 stands' in the press frame with its lower. end pivotally connected to the frame by a pin 21 -and with its upper end connected to the lower arm 17 of the presslever 15., The connection between the upper moving end of the swing arm 20 and the lower end of the press lever 15 consists of relatively movable means as for example a pin 22 which is V fixed in the upper end of the swing arm 20 and this pin floats in a slot 23 made in the 1 lower end of the press lever 14. The fact that the swing arm 20has its lower end pivotally connected to the arm and'the fact that the press lever 15 is pivotally mounted on the shaft 16 requires that some suitable mov- I able connection be employed to operatively hook up the two arms 17 and 20. The swing arm20 is employed for transmitting motion and power from a pedal to be described to v the press lever 15 and is employed as well I for aiding incounterbalancing the press head.

A weight arm 25 is carried on the upper end of the swing arm 20 and projects up wardly at an angle toward the front of the press. A weight 26 is fixed on the weight arm. This weight arm tends to gravitate downwardly thereby urging the swing arm 20 to moveclockwise thus tending to lift the press jaw 13' and open the press. The function of the weight 26 is to'balance the heavy 1 head 13 and this weight is placed under the press within the frame out of the way to permit the machine to be made small and compact in size.

A press pedal with a foot piece 29 located down close to 28 has its front end equipped the floor while its rear end is pivoted near the upper endof the-"link 20 on the pin 30.

In this way the pedal 28 sets at an angle:

its lower pedal end 29 is close to the floor. The pedal end 29 undergoes a relatively short movement in opening and closing the press and therefore an operator is not requiged 'to lift his foot high off the floor to reach the pedal.

A kick-oil pedal embodies a link or arm 32 having one end pivoted at 33 in the press frame and the other end pivoted at 34 to the main pedal 28. The link 32 is made in the form of a kick-off pedal and to this end a pedal arm 35 is made integrally with the link 32 and extends forwardly and to one side of the pedal 29. The kick-oil pedal 35 is made with a foot piece 36 which is depressed to produce an upward lift on the pedal 28 to break the toggle structure 283 2 to initiate the press opening motion. The pedal 28 to ether with the link 32 constitutes a toggle w ich breaks upwardly as shown in dotted line diagram to allow the press head 13 to open under the influence of the weight 26.

In the operation of this pressing machine, work is placed on the buck 12 when the press stands in open dotted line position. The operator now closes thehead by hand or by foot power or by both. Light pressure on the pedal 29 causes the link 32 to move downwardly from dotted line position to full line position shown in the drawing thereby causing the pivot point 34 to travel downwardly past a straight line defined between the two pivot points 33 and 30 which is to? say that the toggle 2832 locks by action of the pivot pin 34 having moved past the center line of the toggle. In other words the toggle comprising the ed'al 28 and link 32 reaches overstraightene position to lock-the press closed under compression.

In this way the press jaws remain closed tight under compressionand a e held in that position by the locked toggle 2832 until such time as the operatorste s upon the foot p ece 36 ofthe kick-off peditl to break the plvot point 34 upwardly past the aforesaid center line drawn between the two points 30 and.33 whereupon the press ispermitted to open.

A press is therefore produced which has operating means, i. e. press opening and closinginstrumentalities which includes a pedal, 7

the link portion 28 of which, extends rear-- wardly and upwardly at an angle to connect with the swing arm 20 above its frame pivot 21, while the front end of the pedal is disosedin a low position convenient to ones oot. The upper and rear end of. the pedal pivotally connects with the swing link 20 at a point between its two pivot points 21 and 22. Any suitable means, such as the link'or arm portion 32, swingablymounts the front end of the main pedal link 28 in the frame, and'this means also includes a kick-off or press openingpedal.

bination The two arms or links 17 and 20 form a toggle pivoted in the frame at 16 and 21 and the pedal 28 is connected therewith at some point intermediate the said toggle pivots l6 and 21. Any suitable counterbalance weight means, such as 2526, cooperates with the toggle 17-20 to balance the opening and.

closing movement of the press.

. A sliding pivot means, such asa pin and slot connection 2223', is included in the press operating mechanism by which relative movement is attained between moving parts in order that one end of the press lever, say the arm 17, may perform the function of a toggle. This sliding pivot means maybe placed at any suitable point.
