8 Claims. (Cl. 68-9) My invention relates to garment pressing mathe above purposes which may be readily rechines for use in tailoring, dry cleaning, laundermoved from the press for repair or replacement; ing, clothing manufacturing and other establishand the provision of a check in which the wear ments for steaming, shaping and pressing garmay be readily taken up and which is easily admerits, and the invention relates mare particularly justable for controlling the checking action; and 5 to means for actuating and controlling movein which the friction or breaking means are selfments of the movable pressing element or member. centering.

the pivots 26 and 28 are alined in a plane intersecting the lever 22 approximately at an angle of 45 degrees. It will be apparent that the relative positions and movements of the pedal lever 22 and link 25 are such that their action during closing of the press affords an easy start to move-'- ment of the parts about to be described.

The primary link 27 is pivoted at 30 to the self-alining thrust bearing 29, which will be hereinafter described in details of construction and purpose, and to one end of the secondary link 31 of the first toggle at 32. It will be noted that in the open position of the press, the pivot 32 is in the same plane with the pivots 26 and 28 to the left of pivot 28, but that in closed position it is at the right of pivots 26 and 28 having swung through an arc thereacross during closing of the press. The secondary link 31 of the first toggle is provided with a counterweight 33 at its other end and is pivoted at 34 to the primary link 35 of the second toggle, which is pivoted at 36 to the frame 10 and which is provided at one end with a counterweight 37. The secondary link 38 of the second toggle is pivotally connected to the primary link 35 at 39 and to the main lever 20 at 40.

The parts 15, 18, 20, 38 and 35 in both open and closed position of the machine are disposed in the same relative positions in which the corresponding parts are disposed in the patent to H. G. Beede, No. 1,661,153, but in that patent the link corresponding to the link 35 is connected to the pedal lever by a single link which only exerts a direct pull on the part corresponding to lever 35. Under the present arrangement, much greater pressure is obtained on the upper pressing element by the system of triple toggles arranged as described above and as will be obvious the operation is accomplished with much less effort on the foot pedal 24. The present invention can be applied to .machines embodying structure similar to that disclosed in the above identified patent.

In order to lock the head closed for continued pressure on the garments disposed between the head and buck, the first toggle, parts 27 and 31, may be so adjusted as shown in the drawings whereby they assume a position in which the pivot 32 moves beyond a line between the pivots 30 and 34. This is the preferred manner of looking the press closed for continued pressure, andin order to break the toggle lock and open the press, I provide an independent trip pedal 41 adjacent the foot pedal 24. This trip pedal 41 is fulcrumed to the frame 10 at 42. An extension 43 on the foot lever 22 is disposed immediately above the inner end of the trip pedal 41 when the press is locked in closed position as shown in Fig. 1 and in order to break the toggle between links 27 and 31, the operator depresses the outer end of the trip pedal 41 with sufiicient force to lift the inner end against the extension 43 to raise the foot lever 22 sufficient to carry the pivot 32 above the line between pivots 30 and 34 following which the counterweights 17, 37 and 33 will move the parts to which they are attached to carry the head 14 upwardly and return the links to the position shown in Fig. 2.

The thrust bearing 29 comprises a preferably round shaft flattened at one end around the pivot 30 where it is joined to the primary lever 27. The thrust bearing is mounted within the recess 60 and is rotatably secured therein by means of the bolt and nut 61. It will be obvious that the thrust bearing takes its thrust against the end of the recess 60 and can partially rotate in recess 60. Thus the primary lever 27 being connected to the movable thrust bearing instead of to afixed pivot on the frame, there will be no binding when the links are operated to close and open the toggles to move the head 14 to and from the buck 12 in the manner which will be obvious from the foregoing description.

In order to check the return ofthe head 14 to open position against sudden and jarring movement, I provide the friction check 50, which is shown in detail in Figs. 3, 4, and 5, and which comprises the housing 51 having a flange 52 engageable around the opening 53 in the front of the frame 10 and secured to the frame by bolts 54. The forked lever 55 is pivotally connected to the casing 51 at 56 and is operatively associated with friction check mechanism within the casing and hereinafter described in detail. The link 35 has an extension 57 provided with the roller or lug 58 which is embraced between the forks of the lever 55 so that as the extension 57 moves with the link 35 upwardly and as the press fulcrums, it turns the arm 55 on shaft 56 and operates the friction check mechanism within the casing 51. Shaft 56 is removably held in the casing by the cotter pin 56'.

As has been mentioned, the arm 57 of the link 35 is provided with a lug or roller 58 which is disposed between the arms 63 of the lever 55, the lever having spaced arms 64 which are journaled on the shaft 56 through the housing 51 for oscillating movement as shown in dotted lines in Fig. 4. A pawl 65 is pivoted to the lever 55 at 66 and bears against a spring 67 which. is mounted between the pawl and an extension 68 of the lever 55. The ratchet wheel 69 is journaled on the shaft 56 and is reduced on each face as at 70 to provide seats for the brake discs 71 outside of which are the friction plates 72, each including a circular plate mounted on the shaft 56 and an integral offset extension 73 outside of the lever arms 64. Screws 73' hold the friction plates against rotation. One plate 72 has a rib 74 formed diametrically thereacross abutting one surface of a forked lever 75 which is pivotally mounted on the housing at opposite points on rods 76, 77. The adjusting screw 78 has screw threaded engagement through an opening in a boss 79 on the housing and abuts a spring 80 seated in a recess 81 in the lever 75.

When the press is in open position, the pawl 65 is in the full line position shown in Fig. 4 and as the press head is moved to closed position, the arm 57 swings downwardly to carry the roller or lug 58 through the are shown in dotted lines in Fig. 4, during which time the pawl 65 is moved downwardly with the lever 55 across the ratchet teeth so that none of the parts within the housing except the lever arms 64 move. However, when the press is opened the arm 57 swings up carrying the lug or roller 58 through-the same are thereby carrying the lever 55 up with the pawl 65 engaged against one of the ratchet teeth on the ratchet wheel 69 whereby the ratchet wheel is rotated against the friction discs 71.

It should be apparent from the foregoing description and the disclosure of the drawings that the friction discs, the arms 64-of the lever 55 and the friction plates and ratchet wheel are all carried on the shaft 56 and are free to move endwise of the shaft so that pressure applied by the lever 75 on the rib 54 at opposite points of the shaft 56 produces equal pressure on both brake discs and on both sides of each brake disc. This pressure can be adjusted, that is, increased or diminished by adjustment of the screw '78 relative to the spring 80 so that if the machine,

is delivered in properly adjusted condition and the arm 15 returns to open position at a properly regulated speed due to proper adjustment of the friction check and then due to wear on the brake discs, the arm 15 returns to open position too fast, the screw 78 can be readily adjusted until the proper braking is had. It should also be obvious that the brake discs can be readily replaced, as the friction check housing is removable from the frame 10 simply by removing the bolts 54 and withdrawing the shaft 56 to permit removal of the old brake discs and insertion-of new ones. In fact any of the parts of the friction check can be readily replaced in the same manner.

As has been explained, when the foot pedal 24 is depressed, the lever 22 pulls on the link 25, which in turn pulls the primary lever 2'7 from the position of Fig. 2 to the position of Fig. 1, wherein the pivot 32 passes a line through the center of pivots 30 and 34 and during which movement arm 15 is moved by the toggle members 18, 20, 35 and 31 to closed position. Of course, the weights 1'7, 3'7 and 33 have been raised and are held in raised position by the locking action of the toggle links 27 and 31 due to the location of the pivot 32 beyond the line through pivots 30 and 34. When the press is to be opened, the trip pedal 41 is operated against the extension 43 "to break the toggle lock and permit the Weights 17, 3'7 and 33 to return the toggles to the position of Fig. 2 while raising the head 14. The action of the friction check takes place to absorb the sudden release of rebound force almost immediately upon or simultaneously with the breaking of the toggle joints to permit the weights to return the head to open position because as soon as the toggle joints are broken, lever 35 begins to move under the action of weight 3''! and the arm 5'7 swings upwardly with the pawl 65 engaged against one of the ratchet teeth on the ratchet wheel 69 and the ratchet wheel is constantly in adjusted frictional engagement with the brake discs '71.

In Fig. 5, I have illustrated by graphic chart in connection with a diagrammatic view of the arm 57 and friction check parts, the theoretical and actual motions showing that if the opening motion of the press was produced by true rotating motion, the friction check would have a friction increase as the press opens, whereas the opening of the press controlled by the toggle mechanism actually produces a decrease in friction as the press opens with a decided excess of friction at the start. This provides or affords a decided advantage in checking the sudden release of pressure, as the momentum is impeded at the start of the opening of the press.

While I have shown the friction check in connection with a triple toggle pressing machine system, I wish it to be understood that the same may be applied to other arrangements of toggle mechanism wherein upward motion is imparted to the head upon breaking toggle joints in accordance with the action of the levers and counterbalanced weights.
