This invention relates to laundry presses and more particularly to multiple unit presses.

Among the objects of the invention are:-

lTo provide a multiple unit press which will occupy a iloor space approximately equal to that of a single press.

To provide a multiple unit press in which the units are successively brought into operative position relative to the operator to minimize movement on the part of the operator.

To provide for the operation of any of the units continuously should breakdown occur to other units or should the nature of the work so require.

To provide for maintaining more than one of the umts with their buck and head separated or compressed as desired.

These and other objects are attained in a cgnstruction described in this specification and illustrated in the drawings forming a part thereof, in which Fig. 1 is a side elevation of the machine having a pair of presses, with the upper unit in operative relation to the operator.

Fig. 2 is a sectional elevation showing the lower unit in operative position relative to the operator.

In the preferred construction illustrated in the drawings, a frame II) has vertical guideways II and I2 on each of two sides thereof. In the guideways II are slide frames I3 adapted to move vertically therein and to which are attached the presses I4 and I5 in vertical spaced relation to each other. 'I'he respective buck members I 6 and I'l are preferably slidably mounted on the frames I3 to permit horizontal displacement against the action of springs I9. The respective head frame members 20 and 2| are plvotally mounted on the iixed shafts 22 supported by the slide frames I3. At each end of each shaft 22 is keyed a member 23, and a pair of links 24 plvotally connects the free extremity of each member 20 and 23 to a roller 25 and of each member 2| and 23 to roller 25'.

(c1. ca -9) The slide frames I3 with the presses supported thereby are counterweighted by means of the slightly lighter counterweight 26 suspended by cable 2l over pulleys 28. Each head member 20 and 2l has projections 20 and 2I respectively 5 which are adapted to force the buck members I6 and I'I respectively forwardly, i. e., to the left as shown in Figs. 1 and 2 when the head is separated from the buck. A compressed air operated piston in cylinder 29 is connected to each 10 of the slide frames I3 so that upon admission of air into the cylinders 29, the presses I4 and I5 are caused to move up and upon outlet of said air out of the cylinders 29, the frames I3 with their presses are caused to move downward by gravity.

In each of the guideways I2 is slidably mounted the cam member 30 having a runway 3I of pref-V erably vertically disposed straight contour a portion of which forms the indentation 32. Rollers and 25 are adapted to move in the runway 3|. The cam members 30 are adapted to be moved vertically by air motors 33 adapted to operate similarly to motors 29 for the presses. An auxiliary 'adjustable cam portion 34 com- 25 prises preferably a circular member rotatably mounted on cam member and having a straight runway portion 35 and an indented portion 36. Each is adapted to form a continuation of runway 3I and is retained in that position by 30 a pin 31.

The control levers 38 and 39 are disposed preferably at the front of the machine so as to be readily accessible to the operator for manual operation. Lever 38 is adapted to operate the 35 compressed air intake valve 40 from tank 41 to cylinders 33 only while the operator depresses same against the action of a spring 4I, a latch 42 being also provided to engage projection on lip 42 to hold lever 33 after the operators hand 40 had been removed from the lever. When lever 38 is in the released position, the intake valve 40 is adapted to be closed and the outlet valve 43 to be opened. Lever 39 actuates the intake valve 44 for cylinders 29 when it is depressed to open 45 valve 44 and simultaneously closes the outlet valve 45 for said cylinders 29. When lever 39 is raised in accordance with Fig. 8, valve 44 is closed and valve 45 is opened.

The operation of the machine is accordingly as follows:

With the presses disposed as shown in Fig. 1, the operator lays the garment on buck I6 which is in its forward position at a convenient elevation for the operator. The operator then depresses lever 39 which causes valve 4U to open and valve 43 to close, so that the compressed air stored in tank 4l is admitted into cylinders 33 and forces their pistons and consequently the cam members 30 connected thereto upward. Roller 25 which at the time is in the indented portion 32 is thereby forced leftward. The motion is transmitted through links 24 against the head frame to cause its movement toward itsbuck I6 until the two are in compressed relation. It is noted that the buck I6 had been forced to recede by the action of spring I9 held under tension by the stud 54 fastened to support I3 as the head starts its downward movement in r view of the release of pressure by the projection 20 against lug 50 on buck arm 52, allowing a small movement of the buck I9 equal to the length of slot 5I in buck arm 52. The arm is supported by and slides on bracket 53.

The operator continues to hold the lever 38 depressed and with the other hand depresses lever 39, which causes valve 44 to open and 4valve 45 to close and thereby forcing the pistons in cylinders 29 up. The slide frames I3 are thus moved up and press I4 is moved out of the way and press I5 into the operative elevation previously occupied by press I4.

As soon as the presses have started moving, the operator releases the levers 38 and 39. Lever 39 remains in the position set while lever 38 is caused to move up by the action of spring 4I, so that the valve 40 is closed and valve 43 is opened. Aided by gravity, springs 45 force the cam members back into their former position, so that when roller of press I5 reaches the operative elevation, it is forced into the indentation 32. The head frame 2| is thus raised to separate head from buck and projection 2| forces buck I1 outwardly so that the operator may conveniently remove the pressed article and lay another article thereon.

When the operation on press I5 is completed, the operator depresses lever 38 to close the press before any vertical movement of the closed press members is started and then raises lever 39 to move the presses down again. Upward movement of lever 39 causes valve 44 to close and valve 45 to open and the slide members with the presses I4 and I5 move down gradually as the air in cylinders 29 is gradually emitted. Whereupon the cycle is completed and the operation continued. The inclusion of motors 33 is for the purpose of closing the press while in the stationary position in order to clamp the work before the vertical movement commences. If attempt be made to move the buck with the article laid upon it with the head raised, the article might be moved out of position. The danger of disturbance, however, is no longer present after the article has been clamped between the head and the buck and 'if this clamping be maintained during the movement. In certain types of work it may prove desirable momentarily to separate the press members to permit the release of steam and inspect the work after the first contact with the garment, but this feature will not be required in all machines or in all uses of the machine. Moreover, if one of the two bucks only is to be used, the corresponding head may be operated by the motors 33 without using the motors 29. The provision of the motors 33 also provides additional functions, as for example, the adjustments of the cam positions to permit the varied operations of the machines -as herein described.

Should the operation of only one press be desired, lever 39 need not be actuated. but latch 42 is released instead and when .lever 33 is depressed the latch becomes engaged sothat the press is retained in compressed position until the operatar releases the latch 42. 5

Occasions often warrant that both presses remain open. as would be advisable when shut oif for the night. Each auxiliary member cam portion 34 may then be rotated so that its indentation 35 aligns with runway 3i. 'This can be done only after the retaining pin 31 had been removed, being replaced after the adjustment.

In case one press is to be used at a time and in order to prevent the padding from being damaged by continuous contact of the heated headv 15 each upper auxiliary cam member 34 may be preferably adiusted so that press I4 stays open while press I5 is operable.

It will thus be seen that a structure has been fully disclosed that meets the requirements of practical use and whereby the various objects of the invention are attained. 0f course, many changes in construction and arrangement of parts can be made without departing lfrom the spirit of the invention. It is therefore intended 25 that all matter contained in the description and drawings shall be interpreted as illustrative and not in a limiting sense except as hereinafter claimed.
