a showing the pressure developing mechanism .in

a position in which the shoe is moved into contact with the buck. Referring to the drawing, the pressing memberscompriseaheatedshoe I andapaddedbuck portion 3 of a hollow base 4. The buck is rec tangula'r in shape. and the upper surface of the buck is inclined upwardly from the front so that the clothes to be ironed may be more conveniently arranged on the buck. At the rear of the buck, the top wall of the base israised to provide an 2. The buck is suitably supported on a raised apron I which prevents the surplus of the matei'ial being ironed from falling over the rear edge of the base. The numeral indicates a U-shaped carriage for supportingthe shoe and for moving the shoe into and out of register with the buck. The cross section of the arms of the carriage is channel shaped, as shown in Pig. 3, and comprises flanges I which are connected by a web I The lower-arm 4 of thecarrlage is pivotally supported on the base on a rod llrcarried between the 'side wallsll of the base. The ll fits within inclined elongated slots l2 which are formed in the flanges "I. Hie front end 'of arm 2 is provided with a notch i2 which-is adapted to engage a rod l4, likewise carried between the sidewalls of the base. The upperside of the notch II is extended toprovideastop llwhidrpreventstof is in the position shown in Fig. 1, it is locked in the position shown and cannot be displaced by forces perpendicular to the face of the shoe. The carriage may be pivoted rearwardly to move the 5 shoe out of register with the buck by sliding the carriage rearward until the notch I2 is clear of the bar l4, and then pivoting the carriage on rod II. The elongated slots l2 permit this rearward sliding movement. The base is' provided with spaced guides II which engage both sides of the arm 9 and guide the pivotal and sliding movement of the carriage. I

The shoe'is supportedon the upper arm H of the carriage, as shown in Fig. 3, by brackets I8 which are fixed to the "inner side of flanges I.

Each. of the brackets carries a bushing l9 within which slides a stud 20. The lower end of each stud is'threaded into the upper side of the shoe, and at the upper end of each stud is a washer 2|. which is held in place by a pin 22. Coil springs 22, surrounding the studs 20 and arranged between the brackets l8 and the washers 2|, bias the shoe toward the lower side of the arm I l. Cylindrical sleeves 24 which are fixed to the brack- 25 ets ll enclose the springs. This arrangement permits the shoe to be moved relativeto the carriage and also permits tilting of the shoe to accommodate unequalthickness oi the material being ironed.

The pmsure'developing mechanism for moving the shoe away fromthe carriage into pressing engagement with the buck comprises a link 25 which is pivoted on a rod 2i carried by a bracket ,21 at the front end of arm ll. The link 25 comprises a pivoted member 25a to each edge of which is fixed a side plate 28. Between the side lower end of the operating lever projects beyond pin 20, and the projecting end 34 is provided with I a pin 25 on which a roll 28 is rotatably carried by an anti-friction bearing. The roll 28 contacts with the upper surface of a plate 21 which is fixed to-the shoe. At the right-hand end of link 25 is a pawl 38 which is pivoted on a pin 29 fixed between flanges 28. The pawl is urged in a clock- 7 wise direction by a spring 40 arrangedfbetween a pin 4| on one of the plates 28 and a pin 42 proiecting from the pawl. The pawl is held against movement by the spring 49 by a pull link 43 connected at one end to pin 42 and having the other end 44 bent to extend behind the operating lever 29. As long as the pins 3| hold the operating lever 29 in fixed relation to the link 25, the pawl "is held in the position shown in Fig. 2. While the lever 29 and the link are held in fixed relation, movement of the lever 29 in a clockwise direcin Fig. 5. As soon as the pressure between the buck and the shoe reaches a predetermined value, the resistance offered to movement of link 25 issuch that the pins 3| move from the notches 33,

and the lever 29 pivots in a clockwise directionabout the pin 30. As shown in Fig. 5, this movement permits the pawl 38 to be moved in a clockwise direction by spring 40 and thereby to engage one of the notches 45 in a plate 46. The plate 46 is supported by-an inclined bracket 41 which is fixed to the flanges 1 of the upper arm ofthe ing ironed are inherently compensated for.

the start of this movement.

carriage and to ears 48 which are struck up from the webof the upper arm of the carriage. As soon as the pawl has been moved by the spring 40 to the position shown in Fig. 5, the link 25 is locked to the carriage in the position shown. Further clockwise movement of the lever 29 causes the lever to pivot about the pin 30, and the roll 36 to move the shoe into final pressing engagement with the buck. The dotted lines in Fig. 5 show Roll 36 acts as a cam during this latter movement of the lever. By this arrangement the leverage exerted by the lever 29 is increased so that the final pressing engagement requires less efiort. In other words,

during the time when the lever 29 and link 25 move together, the pressure developing mechanism may be considered as a relatively low pressure mechanism which will quickly move the shoe into contact with the buck. When the lever 29 pivots on the link 25, the pressure developing mechanism is relatively a heavy pressure mechanism by which the operator can easily develop the required ironing pressure between the buck and the shoe. The position to which the link 25 is moved during the initial movement of the op erating lever 29 depends upon the pressure developed between the buck and the shoe so that variations in the thickness of the material be- At the end of the clockwise movement of lever 29, the roll 36 is moved to the left of pin 30 so that the reaction of the pressing forces holds the roll in this position. The end of member 25a provides a stop which limits the movement of the lever 29.

To relieve the pressure between the buck and the shoe, the operating lever 29 is rotated in a counter-clockwise direction returning the lever to the position shown in Fig. 5. In this position, the pins 3| are slightly to the right of the notches 33 in the plates 28, and the pressure between the buck and the shoe is substantially decreased. A

slight additional counter-clockwise movement of the operating lever will cause the link 43 to dis'-' engage the pawl 38 from the plate 46 and cause,

The pressure developing mechanism is enclosed by a cover 49 fixed to the upper arm of the carriage, and a handle 59 secured to the cover is provided for moving the shoe into and out of register with the buck.

In the use of the ironing press, thematerial to be ironed is arranged on the upper surface of the padded buck 2, and the shoe is moved to theposition shown in Fig. lby means of the handle 50,

In this position, the shoe is in register. with and in spaced relation to the buck, and the carriage is locked in'position so that itcannot be displaced by forces perpendicular to'the'face of the 7 shoe. While holding the handle 59, in .order to preventrearward sliding of the carriage, the operating lever 29 is moved in a clockwise direction,

as viewed in Fig. 2. During the initial part of this movement, the lever 29 and the-link 25, which.

are held in fixed relationlby the pins 3'|,'rotate about the rod 26 and quickly move the shoe into contact with the buck. As soon as the pressure between-the buck and the shoe reaches a high enough value, the pins 3| can no longer maintain the lever 29 and the link 25 in fixed relation. At

this time the pins 3| move out of the notches 33, and the lever 29 then pivots, about the pin 30. During the initial pivoting movement of the lever 29 about the pin 30, the pawl 38 is moved in ,a clockwise direction by spring 49 from" the position in Fig. 2 to the position in Fig. 5. In this position,'the pawl engages one of the notches 45 in plate 46 and locks the link 25 in position. Further clockwise movement of the lever 29 now causes-the roller 36 to move the shoe into final pressing engagement with the buck. At the end ofthe clockwise movement of the lever 29, the roll 36 is moved to the left of the pin 39 so that the reaction of the pressing forces holds the parts turned to thenotches 33, and the link 43 rotatesthe pawl 38 in a counter-clockwise direction disengaging the-pawl from the plate 46. The upper surface of the buck may now be uncovered bypushing rearwardly on the handle 50 so that the notch l3 of the carriage moves clear of the rod M in the base and then pivoting the carriage rearwardly on the rod I0.
