9 Claims.

Our invention relates to a garment pressing machine of the type including head and bed members that are moved into and out of pressing engagement.

One object of our invention is to provide a pressing machine wherein the pressing head is pivotally mounted to swing into and out of pressing engagement with a pressing bed and wherein the pressing bed simultaneously and synchronously moves horizontally with swinging of the head toward pressing engagement into pressing position` relative to the head from a point well forwardly of such pressing position, and moves horizontally simultaneously and synchronously with the swinging of the head out of pressing engagement back to its position well forwardly of such pressing position, there being means provided whereby the head first moves out of contact with the pressing bed, after a pressing operation, before the last mentioned horizontal movement of the pressing bed takes place to thereby prevent distortion of the work on the pressing bed.

Another object of our invention is to provide a pressing machine of the above type wherein the bed member is moved horizontally into pressing position with the swinging of the head downwardly towards pressing position and horizontally out of such pressing position with the swinging of the head away from pressing engagement in timed relation with movement of the head and without the provision of additional power unit means over that normally supplied for swinging the head member into and out of pressing engagement with an immovable bed.

Various other objects and advantageous features of our invention will be seen in the following description and one embodiment thereof may be Vseen in the accompanying drawing wherein similar characters of reference designate corresponding parts, and wherein.;

Fig. 1 is an end elevation showing a pressing machine constructed inaccordance with our invention, the View likewise showing the position of the head and bed members and operating parts at various points in the operation of the machine; Fig. 2 is a fragmentary front. elevation of the pressing machine shown in Fig. 1; and Fig. 3 is a View taken on the line 3-3of Fig. 1.

In the drawing, we have shown apressing machine consisting of a supporting frame I carrying a pedestal 2v thereon which supports a pressing bed 3. An arm II extending outwardly and up- Wardly from the rearward side of the frame I has a head arm` 5 pivotally mounted'thereon as at 6 (Cl. (iS-9) and carrying on one of its ends a head 'I adapted to be' swung upwardly and downwardly into and out of pressing engagement with the bed 3.

The means for swinging the head 'I into and out of pressing engagement with the bed 3 consists of a cylinder and piston motor means 8, the piston rod 9 of which is connected to one of the two inter-connected links IB of a toggle mechanism as at I'I. The ends of the links I0 opposite their point of inter-connection I2 areconnected to the frame' I and one end of the head arm 5 at I3 and I4, respectively. Outward movement of the piston in the cylinder of the motor means 8 to straighten the toggle and thereby swing the head i downwardly about the pivot 6 and into pressing engagement with the bed 3 is accomplished by fluid pressure through a line I5 controlled by hand operated control valves I6 connected in series or in sequence in the fluid line to provide two hand control means. Movement of the head I out of Vpressing engagement with the bed 3 and breaking ofthe toggle when fluid pressure is allowed to exhaust from the cylinder of thefmotor means 8 is accomplished by means of a spring or springs I1 connected to the frame I and the headarm 5 at theY opposing ends thereof as shown in Fig'. 1.

In accordance with our invention, the pedestal 2` carrying the bed 3 is mounted to slide horizontally from the front to the rear of the frame I` in a pair of guides IB (see Fig. 3), the pedestal 2 carrying a work table I9 thereon by means of a pair of brackets 2B. Mounting of the work table I9 on the pedestal 2 to slide therewith prevents possible disarrangement of work on the bed 3 as might occur if the bed moved relative to the work table I9. As shown in Fig. 2, the guides I8 take the form of oppositely disposed U-shaped members in which anges 2| on the bottom of the pedestal 2 are adapted to slide, whereby the pedestal 2 and bed 3 are permitted to move horizontally but prevented from moving vertically relative to the frame.

MeansV have been provided for moving the bed 3 forwardly to a position well in front of its normal pressing position and out fromunderthehead 'I simultaneously and synchronously with swinging of the head I upwardly, and reversely moving the' bed 3 horizontally back into pressing position under the head 3 simultaneously and synchronously with swinging of the head 'I downwardly towards pressing position. This means consists of an arm 22 integrally formed with the head arm 5 and moving therewith. The free end of this arm 22 is connected to the ped- Aso `indicated by the numeral 33.

a housing 24 and having an enlarged head portion 25 thereon between which head and the inner end surface 26 of the housing 24 a spring 21 is disposed, the spring surrounding the link 23. The opposite end of the housing 24 is pivotally connected to the pedestal 2 as at 29 by a link 28 having its opposite end rigidly connected to the housing 24 as by means of the enlarged head portion 3B within the housing and the locking nut 3l on the link and on the outside of the housing.

In Fig. 1, the operating parts in full line position show the press open with the pressing head 1 raised and the pressing bed 3 advanced to a position well forward from the pressing position shown by the dot-dash lines wherein the bed is in aligned position to be engaged by the pressing head 1 when it is swung downwardly. In this position of the bed and head, the operator isfree to make a lay without hindrance and mental hazard produced by the presence of a heated head immediately over his or her hands or arms. Also, the operator has a clear vision of the entire pressing bed surface which permits of a faster laying of the work, the operator being substantially away from the direct rays of heat radiating from the'head. In addition, such relative positions of the head and bed members reduce the chance of accident to the operator by the press closing.

After the proper lay is made on the bed 3, the control handles 32 of the valves I6 are operated which produce movement of the piston in the motor means 8 and a straightening of the toggle made up of the links lil, such straightening resulting in downward movement of the head 1 towards pressing engagement with the bed 3. Movement of the head 1 downwardly causes movement of the bed 3 horizontally rearwardly to the position shown by the dot-dash lines and Such horizontal rearward movement of the bed 3 will continue with the downward movement of the head 1 until the pedestal 2 strikes stop pins 34 provided at the rear of the guide members I3. Such stop pins are adjustable to vary the point of stopping of rearward movement of the pedestal 2 and bed 3 by being threaded through bearings 35 and locked in proper position with lock nuts, and the pins support spring members 36 which contact with and serve to reduce the shock incident to the engagement of the pedestal with the stop pins. At this time, the pressing bed is in position to receive the pressing head in pressing engagement, the pressing head being in the dotdash line position indicated by the numeral 31.

The spring connection between the links 23 and 28 in the means for connecting the arm 22 with the pedestal 2 provides a lost motion wherey by the arm 22 may swing further about the pivot 6 in the moving of the press head 1 into engagement with the pressing bed as indicated at 38 by the dash line. At the same time, the pivotal connection between the link 28 and the pedestal 2 allows for the arcuate movement of the lower end of the arm 22.- as shown. The strength of the spring 21 in the housing 24is such that it is not compressed in moving the pressing bed 3 horizontally rearwardly until the pedestal strikes the stop pins 34 wherein the bed 3 is in ironing position relative to the head 1. Then, compression of the spring and a consequent lengthening of the connection between the arm 22 and the pedestal 2 is effective to allow the head 1 to move further I estal 2 by means of a link 23 extending within downwardly into pressing engagement with the bed. Thus, it is definitely assured that the bed is in proper ironing position prior to the engagement of the head and bed for the ironing operation and it is further assured that the placement 5 of the article on the bed is not disturbed or deranged by premature or sliding engagement between the head and bed as they move toward 'pressing engagement.

After the pressing operation is completed, 10 means may be operated to release the uid pressure in the cylinder of the motor means 8 whereby the head arm 5 will be swung clockwise about its pivot by the action of the spring or springs i1. This swinging of the head arm serves to 15 break the toggle made up of the links IB and likewise to raise the head 1 out of pressing engagement with the bed 3 and movement of the bed 3 horizontally forwardly to the position shown by the full lines in Fig. 3 wherein it is out of a 20 position to be engaged by the head 1 as hereinbefore described.

To provide for movement of the head 1 completely out of engagement with the bed 3 before the bed 3 is moved horizontally forwardly and 25 thereby prevent derangement of pressed work on the bed, the lost motion in the connection between the arm 22 and the pedestal 2 is so arranged that it will be entirely reduced before the bed 3 begins its movement forwardly. That 30 is, there will be no forward urging of the bed 3 by the arm 22 until the enlarged head 25 on the link 23 engages the inner surface of the enlarged head 3G on the link 28 and during movement of the link 23 to bring about this engage- 35 ment compression on the spring 21 is released (see Fig. 3). Then, continued swinging of the arm 3 and movement of the head 1 into the position shown by the full lines in Fig. 1 will result in a forward movement of the bed 3 to a 40 position out from under the head 1 as hereinbefore described.

Referring to the drawing and the preceding description, it will be seenthat we have provided a pressing machine wherein the bed member is '45 simultaneously and synchronously moved with movement of the head member toward and into pressing engagement therewith from a position forwardly and entirely clear of the head member wherein a lay can be made on the bed member without interference from the head member, to a position such that swinging of the head member downwardly will bring it into pressing engagement with such bed member. That is, both the head and bed members move, the one into and out of pressing engagement and the other into and out of a position wherein it will cooperate with such other member for pressing engagement and pressing operation.
