This invention relates to garment and laundry pressing machines and particularly to those employing motive power to actuate the press mechanism.

The pressing operation after the pressing elements are pressed together on the ordinary pressing machine requires a certain amount of time and for this reason in many operations, the operator places the article to be pressed between the pressing elements of the press, closes the press and then stands idle or goes to a second press and repeats this operation.

After the second press has been closed then the operator returns to the first press which has now had time to complete the pressing operation and is ready to be openedand another pressing cycle started, after which the second press is ready to be opened, and so on.

In this manner the operator is able to turn out almost double the amount of work possible with one press but it is obvious that a great deal of time and. effort is wasted in having to move continuously back and forth from one press to the other.

Another object is to provide means which will enable the operator to sit down while at work and thus avoid fatigue consequent to continuously standing and also moving from one machine to the other. i

A further object is to provide means for producing a pressing machine which, although able to accomplish as much as a multiplicity of regular machines, yet will occupy only as much floor space as one machine.

Another object is to provide a press in which the angle of the pressing surface can be varied to suit the operator to facilitate loading and unloading.

Another object is to provide means for applying the force or pressure for pressing purposes directly on top of the pressing element without passing this force through a plurality of levers in order to reach this final point of application.

50 Another object is a machine in which the press .55 the following description.

One of the objects of this invention is to provide close with a pivotal movement during the orbital In the drawings;

This pressing machine comprises, generally, cooperative pressing elements having an opening and closing movement, one of said elements, as the buck on which the work is laid, being movable about an axis andthe other or others in an arcuate or orbital path about said axis in syn'chronism with the movement of the buck about its axis, suitable means for actuating the elements, and means for-opening and closing said elements during the movement ofone about its axis, and the other during its orbital movement.

In the illustrated embodiment, of my invention, the element movable about an axis is a buck movable about a horizontal axis and preferably having a plurality of pressing faces on different portions thereof, here shown, as two pressing faces on opposite portions thereof, and the other elements are a plurality of press heads, in the illustrated embodiment two, one for each pressing face of the buck,'the heads having radial movements to open and close the press during the orbital movement of the heads, as the buck is rotated, and suitable means for rotating- 40 the buck and actuating the heads in their orbital paths synchronously with the rotation of the buck. Preferably, the heads are carried by the usual yoke levers, so that the heads open and movement of the heads about the axis of the buck during the rotational movement of the buck, and the means for effecting the opening and closing movement is a cam track having an arcuate portion about the axis of the head, and a radial portion, and a follower on the. head or some part thereof rigid therewith, coacting with the cam track. The. follower tor followers are preferably located relatively to the head or heads to apply the pressure to the head and buck in a plane extending through or located near the median line of both the head and the buck. Also, in the illustrated embodiment of my invention in which a plurality of heads coact with a plurality of pressing faces on the buck, the buck rotates through a complete circle in a complete cycle of movement, and the heads also move through an arc of 360 through a complete cycle, and the radial or opening and closing movements take place successively at the same point in their orbital cycles. Owing to this rotational and orbital movements, the work, after being placed on the pressing face of the buck, that is uppermost, moves away practically out of reach of the operator before the head closes down on the buck, and hence out of position dangerous to the operator, so that safety devices and two hand controls, etc. are not necessary.

In order to simplify the description, since both sides of the press are alike, only one side is described.

Referring to the. drawings, 1 is the main frame of themachine, upon which is adjustably and pivotally mounted a member 2 (Figures 1 and 2) which constitutes means for opening and closing the press and holding it closed.

The buck or pressing element 3 is also rotatably mounted on the same axis as the member 2 by means of the hollow shaft 1, saidshaft passing through the horizontally projecting sleeve or hub 5 of the member 2 (Figures 1 and 2) Any conventional power means is connected to the shaft l or the hub'or sleeve 5 on the member or members 2 and is so arranged as to rotate the buck 3 in a clockwise direction, or the mem ber 2 in a counter-clockwise direction.

The buck 3 has two pressing faces 3 31 one.

.These are here shown as carried by levers 6 1 carried by and pivoted to the buck 3, so that the levers and heads move orbitally during the rotation of the buck 3 and the levers can also move about their own pivots to open and close the heads relative to the buck.

The member 2 has outer and inner arcuate surfaces or tracks 8 and 9 extending around and nearly concentric with the axis of the buck 3 and radial tracks at like ends of: the arcuate tracks, and followers or rollers IB and H rotatably mounted on the heads 6 and l are adapted to engage the radially extending surfaces or tracks 12 and I3 and also the arouate surfaces or tracks 8 and 9 of the members 2 (Figures 1 and 2) Portions [2 I? of the surfaces or tracks l2, 13 are on shiftable parts, each of which is pivotally mounted at 13' on the member 2, and can be swung to the left, as shown by the dotted lines in Figure 1. Each part as pivoted at 13 is virtually a switch member shiftable into a position so that the rollers II), II follow the outer track 8 instead of the inner track 9.

Retracting springs M and [5 connected to the levers 8*, l act 'to hold the rollers Iii and H against the track 8 or 9 of themember 2 (Figures 1 and 2). i

It will now be apparent that with the press in the open position, as shown by the full lines in Figure 1, if the members 2 are held stationary and the buck 3 is revolved in a clockwise direction, such rotation will cause the rollers of the head 6 to roll downwardly along the surfaces l2 and it until the rollers I0 reach the position as shown by the dotted lines in Figure 1 with the rollers ll resting on the beginning of the curved surfaces or tracks 9, and this movement will bring the head 6 down upon the buck (Figure 1) Continuing of the rotation, the rollers I0 will continue to roll in a clockwise direction along the tracks ll until the buck 3 has made a half rotation.

During said clockwise rotation, the rollers ll of the head 1 will also have rolled along the surface c until the rollers H reach the end of said track and the retracting springs then swing the head i to open position with the rollers H resting against the surface I2 in the position formerly occupied by the rollers Iii, Figure 1.

It will now be apparent that the other surface of the buck 3 is now presented to the operator for unloading and loading while the face of the buck formerly presented, is under pressure from the head 6, Figure l.

In other words, during each pressing cycle, the buck 3 rotates one half revolution in a clockwise direction presenting a different pressing face each time it stops and the operator can unload and load the pressing face presented to him while the other pressing face is engaged in the pressing operation.

If it is desired to operate the press mechanism and yet not have the head come in contact with the buck,then the hinged parts or switch members w are swung into a position, asshown by the dotted lines in Figure 1, and then the rollers ill or ii are free to roll from the surface l2 onto the surface 8, and thus the head 6 will not come in contact with the buck 3 (Figure 1). The press may be operated in this way preliminarily. to leaving it idle for long periods.

A threaded stud IS with a hand adjustment wheel ill at one end is rotatably mounted on the member 2 and the other end of said stud engages with the pressure block 18 slidably mounted in the surface 9, and it will be apparent that by rotating the hand wheel I! in either direction, so as to move the pressure block l8 toward or away from the center of the shaft 4, the pressure between the head and buck can be increased or decreased, when the pressure rollers Iii and II engage with the pressure block I8 (Figure 1). The block 18 is in effect a radially adjustable cam on which the rollers H) or I I ride when the head 6 has made a half revolution from open or closed position.

Further pressure adjustment of the rollers l0 and ii is provided by pillow blocks l9 slidably mounted between the guides 28 and 21 on the head 6 (Figure 3) and means, as screws, for adjusting or setting the blocks. As shown a hand adjustment wheel 22 and a collar 23 are mounted on the end of the threaded adjustment rod 24, said rod being rotatably mounted in a cross bar 25 between the guides 20, 21, and engaging with the threads in the pillow block l9, and a shaft 28 mounted in the pillow blocks, on which shaft the rollers it and H are mounted. It will be apparent that raising or lowering of the blocks l9 by means of the hand wheels 22 will move the shaft 26 radially and consequently the rollers in or H toward or away from the pressing surface of the head 6 or 1, and thus decrease or increase the pressure between the'head -6 or I and the buck 3, when said head is brought down upon the buck 3, as previously described, by means of the rollers 10 or moving along the tracks l2, l3 and 9 (Figures 1 and. 3).

to roll along the surface i2 and I3 and down on the surface 9 and finally the pressure block [8 will. be brought in contact with the rollers l0, thus causing any desired preset pressure to be applied between the pressing surfaces of the head i 6 and. the buck 3 (Figure l) A locking latch 2'! is provided to prevent the head i from moving while operating the press in the manner described above (Figure 1).

After the head 6 has been brought down upon the buck 3 by the counter-clockwise rotation of the member 2, then rotating the member 2 in either direction back. to its original position, as shown by the full lines in Figure 1, willallow the head ii to swing to an open position with the rollers Hi resting against the surface 12, Figure 1.

When. the press is used as first described, by the rotation of the buck in a clockwise direction, using first one surface of the buck and then the other, it will be obvious that the operator can stand or sit in front of the press, loading and unloading continuously, and thus. accomplishing the work formerly produced by two machines without the necessity of constantly moving from one press to the other, and also that by adjusting the member 2 about its axis, the loading and unloading position or incline of the buckwhen at the loading and unloading position, can be varied to suit the operator. 1

A locking pin 28 is slidably mounted in a vertical projection of the frame and is adapted to engage in any of a series of holes in the member 2, so that it is possible to lock said member 2 in i any position, and thus control the loading angle of the buck 3. 1

Referring to the wiring diagram, Figure l, closing the switch 29 allows current to flow through the motor M and the subsequent rotation of said motor also revolves the commutator til to which the motor is mechanically connected in a clockwise direction, Rotation of the commutator brings the segment 3! in contact with the brush 32 is for the purpose of illustration. The motion or power of the motor is transferred to the shaft 4 of the buck It when the machine operated by rotating the buck and moving the heads orbitally through a pulley 35 or other motion transmitting means on the shaft.

When the machine is operated as a single press by locking the buck from rotation and moving the members i, the motion of the motor is transferred to the hub of one of the members througha pulley iiii or other motion transmitting part on the hub 5.

The heads and buck may be heated by steam circulating through the heads and which are chambered, the buck being connected in series with each of the heads through flexible piping, not shown, or in any well known manner, and the steam being supplied to the buck through the hollow shaft A. The heating system may be of anysuitable arrangement and forms no part of this invention.
