including drivin and driven elements one of whizh is shittableI into and out ol en-f ga'gement with the other land means for shifting sa-idshiftable element at will. lt also includes a holding means or latch for holding the movable .pressing member in a down or closed position and arranged to be loperated by the power actuated means, and

means for releasing the holding means.

The actuating means further comprises mechanism by whichthe movable member may be caused to vibrate to partly open and close the press and thus alternately and momentarily close the press to apply' pressure and momentarily partly open the press to slightly separate the pressing members so that the vibrating movement causes the movable pressing member to pound on the gar- 4 -ment and also cause a slight alternate sucking and blowing eliect, all to remove steam and moisture Afrom the garment, or other article being ressed.

The invention is here shown as embodied in a pressing machine of the type shown -in patents to A. C. Austin, 'No 1,252,988, J an. 8, 1918, and No. 1,335,151, patented March 30, 1920, inwhich an upper pressing/head is movable toward and from the lower bed or buck mounted on a. suitable frame.

1 designates the frame which may be of 'any suitable form, size and construction. The one here shown, includes a suitable table 2 mounted upon front and rear legs 3,-

4, there being two front legs 3 and a single rear leg 4,.the'se legs are connected by suit? able braces 5. 6 designates the lower pressing element or bu k which is mounted upon a standard or w at is ordinarily called a A goose-neck 6a which in turn' is mounted upon the table .2. 7 is the upper .pressingfmemberor pressing head, which is carried by a frame lever Spivoted between its ends at 9 to the upward extension or bracket 10 of the rear leg 4, the rear' arm of the lever carrying a counterbalance weight 10 and being pivoted'at 11 to -one end of the toggle link` 12,y the other end of which is pivoted at 13 to the upper end of a second toggle link la. 'lhis toggle link 11i in the embodiment of the machine here illustrated is pivoted at 15 iat its lower end to the frame and is provided with aforwardly extending arm or lever 16 rigid therewith and which when operated, tends to,a straighten the toggle links 12 and 14, and bring the upper gagement with a shoulder 19 on the framex and the latch is released by tripping means as a lever 19a pivoted to the frame and when depressedl operating to disengage the latch 17 from the shoulder 19 and permit the weight 10 and also an additional counterbalancing spring 20to open the pressor elevate the pressing head 7. The pressing head 7 and lower buck 6 are usually hollowand heated by steam in any suitable manner, lunnecessary to describe herein, as steam systems for this purpose are well understood by-those skilled in the art.

In addition, the machine is provided with the means for permitting steam to .pass from one of the pressing members 5i or 7 usually the lower buck 5, through the garment or` article being pressed. This means comprises a valve located within a suitable casing 21,

which casing is in communication with the steam system, and means for opening the valve, as a rod 22 connected at its upper end to the valve and at its lowerend to any well known operating mechanism.

The frame lever 8 whichcarries the. press head- 7 is also provided with a suitable handle 25 by which it may if desired be moved by hand toward pressing position preliminary to the application of final or heavy .pressure by the operator'or by power on the pedal 16. l

`The power operated means for operating.' -the movable pressing member, that is, the

upper pressing head 7 is preferably arranged to apply the final or heavy pressure by moving the toggle links into or about the dead i center line of the toggle after the pressing member 7 has been moved preliminarily toward the lower buck 5 and the toggle composed of/the links 12, 14 are not quite in aA v straight or dead center line. However, the

v'power operated means may effect both ythe.

reliminary and final pressure movement,

ut for what might lbe ,called safety first reasons, it is preferableto effect the preliminary movement of the pressing head 7 by operated actuated means that is, hand or foot operated means rather than wholly by member, a driving element mounted on and rotatable with the shaft and a. driven ele- The drive shaft 26 is here illustrated as a shaft driven by an electric motor 27 mounted on the frame, this shaft being journalled 1n suitable bearings formed on the brace 28- extending between one ofthe front and rear legs of the frame, the shaft 26 extending transversely of the frame at an angle to'the.

lever 16, and having a worm wheel 29 thereon meshing with the worm 30 on the armature shaft 31 on the motor, which motor is. also mountedy upon the brace 28 and secured theretol in any suitable manner. .The motor, of course, is connected in a feed circult which is controlled by any suitable switch.

As illustrated in Figure 2, the 'driving element is a cam '.32l mounted on the shaft 26 adjacent the lever 16 and theV driven element is a follower 33 carried by the motion transmitting member, as Athe lever 16, and preferably the follower is shiftable laterally into and out of the path of the constantly rotating cam 32. y

In the illustrated embodiment of our invention, as shown in Figures l, 2 and 3, the' follower is mounted `on a rock shaft 34 eX- tending lengthwise of the motion transmitting member or lever 16 and journalledin suitable bearings thereon and comprises anv thereon. A spring 38 is interposedbetween the arm and the lever 16 and tends to nor` mally rock the shaft to carry the follower pin out of the path of the'cam 32. A pedal 39 is provided on the front end of the shaft to rock the sarnecand also to depress the motion transmitting member `or lever 16 to preliminarily actuate the toggle links 14 and 12 toward a straight linecand efl'ect the preliminary movement of the pressing head 7 toward the lower buck 5:.

In the operation, as thus far described, the operator brings the pressing'-head 7 down toward the lower buck 5 either by pulling downwardly on the handle 25 or depressing the pedal 3.9 and hence rocking the lever 16 on its ivot 15 and also rocking the shaft and fo lower 33 against theffaction of the spring 38.

During such preliminary'movement the end of the follower pin 36 abuts the end face of. the cam 32 and by so doing, limits the roc u" of the shaft so that the pressure apnavarra pressing position and straighteningthe toggle links and also causing the latch 17 to engage the shoulder 19 and hence hold the press inits closed position, that is, its position occupied when applying heavy pressure. When the latch 17 engages the shoulder 19 as soon as the low point of the cam comes opposite the follower pin, the springv 38 rocks the shaft in the reverse direction and moves the follower pin 36 out of the path of the constantly rotating cam 32. Hence upon the operation of the trip lever 19a to disengage latch 17 from the shoulder 19, the press will be opened by the counter-balancing weight 10. and spring 20. However, it upon rocking of ithe shaft 34 and the depressionof the lever 16 by the 'pedal 39, the trip lever 19a is also depres3ed i or held tripped, the roller 37 of the follower 36 will be held engaged with the cam 32 by the friction between the cam and the follower and hence the follower will not have opportunity to return to its starting position by the spring 38 forthe reason that the latch 17 is held from latching with the hook 19 by the trip pedal which is being held depressed. Henee, the friction between the cam and the follower is not relieved and as the follower remains in engagement with the cam, successive vibrating movements are transmitted to the lever 17, toggle links 14, 12, frame lever 8 and upper press head 7 causing the press head 7 to momentarily separate slightly from the lower buck and article thereon and vagain momentarily come intopressing relation. Hence, the press is alternately opened and closed, such action continuing until the operator removes his foot from the pedal 19EIL and permits the latch to e the shoulder 19. "After the latch has momentarily engaged the shoulder '19 long enough to permit the spring 38 to.

shift the follower 13 out of the` path of the cam 32, the trip-lever 1.9a is again operated to release the latch permitting the press to open fully. llt will be borne in mind that jt-his releasing operation of the follower is due to the fact that the follower'and cam are 'a slapping or pounding on the garment and also a slight suction and blowing effect which e'ectively removes the moisture and steam from the garment. rlhe moisture and steam inthe garment is that injected into the garment by depressing the lever which opensV the steam valve 21 heretofore described. rlhe slapping flattens lor smooths out the article better than continuous pressure.

For the purpo ;:e of adjusting the follower .pin relatively to the cam 32 the follower arm is formed with a transverse bearing 40 and the follower pin-36 is mountedeccentrically in an enlargement 43 mounted in the bearing 40 and held from turning by a set screw 44. By loosening the set screw 44 and turning the part 43, thefollower pin 36 and rollers thereon can be adjustedtoward and from the working face of the cam.

follower being shiftable, the cam 45`on the constantly movable driving shaft may be shifted by the operator in the movement of the pressing head 7 toward pressing position.. ln Figures 5 and 6, the cam 45 is slidably mountedon the driving shaft and Ais actuated by means of the shifter or fork 46 engaging the hub of the cam and actuated through suitable connections 47, 48, and spring 49, between the shifter and the lever 16 or some other motion transmitting part.

This connection includes a lever 47 arranged in the path of the lever 16 and motion transmitting part 48, between the lever 47 and the shifter 46. rllhe lever 47 is here shown as having a head 50 arranged in the path of the pedalplate 51 on the front end of the lever 16, the plate having a hole 52 in alinement with the head 50 and through which the headextends as the lever approaches its down position. ln operation, the operator places hisfoot on the plate'5-1 and deprefses the lever 16 to effect the preliminary clos-' ,ing movement of the ypressing member 7.

Toward the end of the preliminary depressing movement the head 50 of the cam shifting lever 47 enters the hole 52, and the foot of the operatorowhich covers the hole encounters the head 50 and depresses the' lever 470to shift the cam against lthe returning spring 49 during the latter part of the movement of the lever 47;

Owing to the constantly moving shaft., the operation of the machine is smooth, fast and without jolts and the motor uses a minimum of current. A

rlhe degree of pressure is controlled for each class of work by adjusting the k,toggle in any well known manner.

In the present embodiment'y of our invention, the link 12 comprises a threaded rod, a thrust bearing or end member 54 at the upper end of the rod and pivoted at 11 to the frame lever 8 and a lower end member or clevis 55 in which therod is slidable end- As seen in Figures 5 and 6, instead of the l.

wisely, the end member 55 being pivoted at 13 to the lower toggle link 14. The rod of the link 12 is endwisely movable in the end member or clevis 55 relatively to the link 14 and is yieldingly held `from such endwise movement by a spring 56 encircling the rod of the link 12, and thrusting at one endy against the upper end of the lower end member 5o and at its upper end against an adjusting nut or wheel 57 threaded on the rod of the link 12 against the upper end of the spring 56. This nut or wheel 57 is locked in its adjusted position by lock nut 58 provided with a suitable handle 59.

These machines are primarily intended to be used in clothing factories'and Vlaundries, where the operator works for one period upon a certain class ofwork, all pieces of which require the same amount of pressure, and therefore, the machine can be readily adjusted to the desired pressure by adjusting the toggle by turning the wheel 57; and when another class of work requiring a dierent pressure is to be operated on, the pressure can be adjusted for that class of work by turning the wheel 57. I

This power mechanism is particularly advantageous in that it isA readily and economically applied to standard machines, and further in that owing to the constantly running lmotor, its operation is fast and smooth and is without violent starting and stopping jolts.

Owing to the latch and to the toggle adjustment, the pressure is readily regulated to a predetermined maximum; and further owing to such power mechanism the garment can be readily dried without additional mechanism, or attachments as blowers, or

vacuum producing attachments.
