v Referring now to the embodiment .of the invention illustrated by way of example in the accompanying drawings, a vertically disposed frame I is shown, having a base 2, the frame being preferably of integral she et material, as for instance welded sheet steel. The vertically disposed part of the frame constitutes the back of the machine, and is preferably box-like and internally hollow, thereby affording support and housing for the actuating and controlling means. The. upper portion 4 of the frame is curved forwardly to constitute an overhang from which'is supported the upper part of the pressing mechanism, and a 1'5 sitting with full freedom to-change position as i straight-line mounting is provided for the pressing mechanism between the head 4 and the base 2 of the frame. The front of the machine is entirely open and the pressing mechanism is mounted at the front of the machine.

In accordance with one feature of the invention, one member of the pressing couple is movable laterally to and fro between a Work pressing position and a work receiving and delivering position, which latter position is directly in front of the operator and at a substantial distance from the pressing station. After the operator has positioned the work, it is carried from the operators station to the pressing station, and after pressing it is returned to the operators station by the movement of this part of the machine.

As embodied, one of the pressing members, such as the pressing head I! is mounted or suspended from the head portion 4 of the frame in a forwardly and outwardly inclined position, and

the other member of the pressing couple, such as the buck I2, is mounted to swing on a pivotal support, inwardly into pressing position in alinement with the pressing head (solid lines, Fig. 2) and outwardly away from the pressing position, past its vertical center, into an outwardly and downwardly inclined work delivering and receiving position (shown in dotted lines in Fig. 2). As shown, the pressing buck I2 is mounted upon a support l3, which at its bottom end has downwardly-projecting, apertured lugs I4, which are pivotally supported upon a shaft 5, which is mounted in brackets l6 and H, fixed to and extending upwardly from the base 2 of the frame. The work support thus has an ample pivotal bearing directly on the machine frame and directly in the line of thrust of the press, and the cooperating presser head is stationary except for the free, straight-line movement to effect the work pressure between the head and the buck. The members I! and I2 of the pressing couple are disposed in inclined position for the pressing action, the entire structure being inclined inwardly and upwardly between the base 2 and the head 4- of the frame, and the ironing pressure is exerted only in the direct longitudinal line of the parts, and also is exerted directly on the presser members, without the use of levers or like mechanisms.

The buck I2 and its pivotally mounted support I3, after the pressing is completed, are caused to swing outwardly from the full line position to the dotted line position of Fig. 2. In this dotted line position, the buck is inclined forwardly and downwardly directly in front of the operator in the most favorable position for rapid and efficient removal of the finished work and for like loading of new work on to the buck. The work is thuspresented directly to the operator at a fixed station, who may be sitting or standing, and the forwardly inclined position of the buck is most favorable to rapid and efficient handling of the work. The upwardly and outwardly inclined support permits space for the operators feet beneath the support in the open position, so that the work is brought within easy and eflicient reach of the operator, in a seated position. The inclined positions of the presser members also give very effective drainage of condensed steam from the heating system. A table l8 may be provided on the support l3 if desired.

Referring now to the embodied form of means for actuating the traveling buck and its support (Figs. 2, 3 and 5), it is designed to be operated by pressure fluid, such as compressed air, and in said form a cylinder 2! is pivotally supported at 22 upon the frame of the machine. The cylinder has a double-acting piston, and its piston rod 23 is pivoted at 24. to the supporting pedestal l3 of the work carrier. The fluid pressure is applied alternately at the two ends of the cylinder 2| to swing the carrier to and fro between the pressing position and the work-receiving and delivering position at the will of the operator. The mechanism for operating and controlling a single press is shown especially in Figs. 2 and 3, and will be first described, and as embodied the compressed air is brought from a suitable source by a pipe 21, which communicates by a short pipe 28 with a valve 29. Valve 29 is connected to the right-hand end of cylinder 2| to apply the air pressure to swing the pedestal it from the workreceiving position, shown in dotted lines in Fig. 2, to the work pressing position, shown in solid lines in Fig. 2.

A pipe 32 connects with the valve 29 and by a flexible pipe 33, which opens into the right-hand end of the pivoted cylinder 2|. The valve 29 is constructed to normally connect its end of cylinder 2| to the atmosphere while cutting off the pressure from pipe 21, and is then in the position of the valve 29 in Fig. 5. Pedal-operated means are preferably provided whereby the o erator actuates valve 29 to swing the work pedestal from the dotted line to the full line posi tion of Fig. 2, and as embodied a spring-pressed foot pedal 31 is pivoted at 38 upon the machine frame, and has a downwardly-extending arm 39 adapted to contact with the end of the valve stem 40 of valve 29, which projects from the valve casing. The stem 4B of valve 29 (Fig. 5) has fixed thereon two valve discs 3-5 and 46, which are located in valve chambers 3 and 4 5, respectively. There is an air port ll communicating between the two chambers, and a spring 48 urges the valve 45 onto its seat to normally shut off the pressure from the pipe 2'5, and the spring holds valve disc 46 open, and pipe 32 and chamber 44, and the right-hand end of cylinder 2|, are normally in communication with the atmosphere.

When the pedal 31 is depressed, valve stem 40 is moved against its spring 68, valve disc 46 is closed, and disc 45 is opened against the spring, and the air pressure from pipe 27 passes through pipe 32 into cylinder 2| and moves the piston to the left, and swings the pedestal it from the dotted-dine work-receiving position to the fullline pressing position in Fig. 2. Fne pedestal comes to rest against a suitable stop, with the pressing buck l2 in alinement with the pressing head II and is held in that position by gravity, and the air pressure is cut off from cylinder 2| by the operator releasing the pedal 3'1, which cuts off the air pipe 21 from the cylinder, and relieves the cylinder and pipe 32 into the atmosphere.

There is provided by one feature of the invention a presser head mounted directly upon the machine frame, and having no other necessary movement except the relatively short, straightline movement required for exerting the pressure upon the work, and this movement is of variable extent, automatically accommodating itself to variations in thickness of the work or of the padding, and thus the full predetermined pressure is exerted on the work under these varying conditions. As embodied, the fluid pressure operates directly upon the presser head at a plurality of longitudinally spaced-apart points with floating pressure, which insures uniform pressure throughout the work, applied directly, and without the intervention of levers or other connections. As embodied, the elongatedpresser head II has projecting from the upper face thereof transverselyedisposed pairs 'of-upwardly projecting rods 54, 55 and 56, 51, the respective pairs being spaced apart along the head. These rods are resiliently supported thereby to hold-the presser head I I yieldingly away from the pressing position, while allowing the air pressure to act directly upon the head ll at these spaced-apart points to press the head against the work; As embodied, two diaphragm chambers 58 and 59 arefixed at 60 and 6| to the head A of the machine frame and extend downwardly therefrom. The diaphragm casings 58 and 59 have, respectively, downwardly-extending cylindrical portions 62 and 63, which terminate in transversely disposed plates 64 and 65.

The pairs of rods 54, 55 and 56, 51, which extend upwardly from the back of the presser head II project through openings in these plates 64 and 65, respectively, and coil springs 69 and I reston the upper faces on the plates 64 and 65 and are in compression between the plates and nuts II and I2, screwthreaded onto the upper ends'of the rods, the presser head II thereby being supported resiliently away from the work position. 7

In the embodied means whereby the fluid pressure moves the presser head I I against the action of the springs 69 and I0 and presses it against the work on the buck I2, there is mounted in each of the cylinders 58 and 59a diaphragm I6, and within said cylinders and on the under side of diaphragm I6 is a loose piston 11, having a central boss I8 to which is fixed a rod I9. The rods I9 project downwardly, respectively, through the hollow cylindrical extension 52 or 63, and these rods I9 have rounded outer ends that fit into cup-like sockets in the back of the presser head i I. The fluid pressure is admitted to each of the cylinders 58 and 59, and the pressure is thus applied independently at two spaced-apart points along the resiliently-supported presser head I I, thereby causing the pressureto be applied conformably and with equal force to all parts of the work, I

Means are provided whereby the ironing pressure against the work is initiated and maintained automatically when the work support reaches the pressing position, and is then maintained automatically, either for a predetermined timeor at the will of the operator. In said embodied form, a valve mechanism is provided which is actuated by the pedestal I3 coming to rest in the pressing position, the valve mechanism turning the air pressure into both diaphragm cylinders 58 and 59, the pressure thereafter being maintained on the work, either until the operator is ready to move the pedestal to delivery position, or after a predetermined time period, as hereinafter described. In the embodied form of valve mechanism, which is shown of somewhat diagram matic form for the sake of clearness (Fig. a

contact lug 99 on the pedestal I3 engages with the stem 99 of a double-disc valve mechanism 9I when in the pressing position, as shown in Fig. 3, and at the left in Fig. 5.

Valve 9| receives the compressed air from a pipe 92, which branches off from pipe 32. The valve is normally held with its disc 94 seated and itsdisc 95 open by a compression spring 96. The valve has a central port 91 communicating by a pipe 98 with a cylinder 99 in which works a piston I00. The piston 100 has a short piston rod which bears onone end of a lever IOI', which is pivotallysupported at I02. On the opposite side of its same end lever IOI bears on the valve stem I04 of a double-disc valve I05 similar to the valves already described. Valve I05 is normally held by a spring I06 with its lowermost disc seated, thereby to shut off the fluid pressure from the cylinders 58 and 59. The valve mechanism comprises also, as a holding. device for valve I05, a cylinder I09 in which works a piston IIO, having a short piston rod which bears against the under side of lever IOI at its opposite end. 'A pressure supply pipe III communicates from the pipe 2'1 to the chamber of valve I05. A pipe II2 leads from valve I05 and supplies the fluid pressureconcurrently to both of the actuating cylinders .58 and 59 of the header II. A pipe H3 communicates from the cylinder I59 to release the pressure in cylinders 58 and 59 and to permit the springs 69 and Illto lift the pressing head I I from the work after the pressing is done.

Themanner of operation of this valve mechanism is as follows: When lug 89 moves valve stem 90 against spring 95, the fluid pressure from pipe 92 is admitted into cylinder 99, and piston I00 is moved downwardly, and thereby opens valve I05 against the pressure of its spring I06, and the fluid pressure passes from pipe III through pipe I I2 into each of the cylinders 58 and 59, onto the diaphragms I5 and their pistons 11,

forcing the presser head I I upon the work carried on the buck I2, and at the same time compressing the springs 59. and "I0. Concurrently the pressure fluid enters cylinder I09 forcing piston H0 upwardly, and lever WI is thus held in open-valve position by the air pressure under piston H0, and with the'fluid pressure maintained on the presserhead I I. This pressure will be maintained until relief of the cylinder I99, either by a relief mechanism operated by the operator in actuating the mechanism for swinging the support I3 back to the work-delivery position, or by the operation of a time mechanism. Any known or suitable means may be employed, if necessary or desirable, for effecting the timing of the parts so that the: pressing action will not begin until the work support is in position. Also, any suitable means may be employed ior heating the pressing members II and I2.

Referring now to the embodied means for moving the work support back to delivery position in front of the operator, a valve mechanism H6, which may be the same or similar to the valve mechanism 29, is connected by a pressure supply pipe II? with the pipe TI. This valve, as stated, is of the same double disc type and is springheld-to shut off the fluid pressure from cylinder 2I. A spring-pressed pedal I29 is pivotally mounted at IZI upon the machine, and has an arm I22 engaging with a longitudinally-slidable rod I23, which when the pedal I20 is actuated against'its spring engages the stem 524 of the valve M5 to open it against its spring. A pipe I25 communicates between the valve H5 and the opposite end of cylinder 2! by means of the flexible hose I25. When pedal I29 opens valve H5, the fluid pressure is admitted to the lefthand end of cylinder 2i (Fig. 3), and the work support I3 isswung from the pressing position to the work delivery position, which latter is shownin dotted lines in Fig. 2. The work support I3 need be moved only over its vertical center by the cylinder 2 I, and then will move by gravity and come to rest inthe work-delivery position 76 against a suitable stop, not shown, and the pressure in the cylinder 2| can be immediately relieved.

The embodied means for moving the presser head I I away from the work, preparatory to this return movement of the work support, comprises a device for relieving the pressure on the piston I III, which is operated by the pedal I29, the parts being so timed that the head II is free from the work before the return movement begins. As embodied, a relief valve I2? is provided for the pipe H3, and this valve is actuated by a lever I28, which straddles the rod I23, and in engagement with a collar I29 fixed on the rod, and when lever I29 is depressed lever I28 is moved to open valve I21 to release the pressure. Thereupon piston IIIl drops, and spring I05 closes the valve I95, and the pressure in pipe H2 is relieved through pipe II3 and valve I21, and springs 59 and I act to lift the presser head II,

In accordance with one feature of the invention, two pressing mechanisms are interconnected to be served by one operator from a single work position or station, means being provided Whereby the operator serves and controls both pressing mechanisms and operates them concurrently in reverse directions. Thus after the work is put on one pressing mechanism, the work support moves to the pressing position and concurrently therewith the work support of the other pressing mechanism moves in the opposite direction, and brings the pressed work in position before the operator to be taken off and for new work to be placed on the support. Thereupon the mechanism is again operated to carry the new placed work to the pressing position, and to move the pressed work on the other pressing mechanism into position before the operator ready to be taken off. This machine is shown in plan in Fig. 4 with the two mechanisms arranged at rightangles to each other, the operators position being indicated by I33. It will be noted that the work supports in the open position occupy in part the same space, due to both machines delivering the work in front of the operator, but there is no mechanical interference for the reason that one support is moving toward pressing position while the other support is moving toward delivery position.

The interconnections whereby the two machines are operated in synchronism are shown diagrammatically in Fig. 5, and in many respects they are the same as the actuating and controlling mechanism for the single machine already described, and only the differences in arrangement need be further explained. The main differences are that the mechanism on one machine for lifting presser head II away from the pressed work, and for moving the work support back to delivery position before the operator, is here controlled automatically by the mechanism on the other machine which the operator actuates to carry the work to the pressing position. Thus when the operator has completed the work on one mechanism, and starts the work toward pressing position, this automatically carries the pressed work on the other machine away from the pressing position and places it before the operator, ready to be taken off.

In this double machine, therefore, the valve 29 on either machine, which moves the work support to pressing position, is also connected through pipe 32 to pipe I25 which supplies fluid pressure to the opposite end of cylinder III of the other machine. The valve 29, when actuated, thereby moves its own work support to pressing position, and at the same time supplies fluid pressure through pipe I25 into cylinder 2| of the other machine, and moves the work support of that machine from the pressing position to the delivery position in front of the operator. In like manner the preliminary retraction of the presser head II from the work is effected by connecting the relief pipe I I3 and valve I2I to be actuated concurrently with the opening of valve 29. For this purpose the relief valve I2'I' is connected to be operated by a longitudinally slidable rod I35, which in this instance is interposed between the actuating lug 39 of the foot lever 31 and the stem 40 of valve 29, and thereby the one pedal is employed to operate in unison the mechanism for moving the work support of one machine to pressing position and the work support of the other machine to the workdelivering position.

In accordance with one feature of the invention, means are provided whereby the pressure upon the work may be terminated after a settable or predetermined time, so as to guard against overheating of the work or of the presser pads. This mechanism is arranged to release the pressure off the work independently of the operation of the lifting mechanism, previously described, which operates automatically when the operator moves the work support back to delivery position. This mechanism has one of its main uses in guarding against overheating in one of the presser mechanisms of the double machine in case the operator is delayed in arranging the work on one machine and starting the return movement, although it will operate equally well on a single machine. As embodied (Fig. 7), a rod I49 is pivoted at I4I to the swingable work-supporting pedestal I3, the rod being pivoted at its other end I42 to a bell crank lever I43 pivotally supported at I44 upon the frame I. The other arm of bell crank lever I42 straddles a longitudinally movable rod I45, and bears against a collar I45. Rod I45 is reciprocable in a guide I41 and is pivoted at its other end I48 to the piston of a dash pot timer I49 having a small port 10 near its lower end and beneath the piston. A relief valve I56 which is part of time mechanism I59 (Fig. is connected by a pipe I5I to the relief pipe H3 and has an actuating lever I52 in the path of a collar I53 fixed on rod I45. When the press is opened, lever I43 is swung to the dotted line positionv and lifts rod I45 by means of collar I46. When the press is closed, and the pressure is automatically applied to head II, lever I43 swings back to the full line position of Fig. 7.

However, the dash pot maintains rod I45 in the elevated position, and it moves down only very slowly under control of dash pot I49, the dash pot emitting the air beneath its piston sufficiently slowly to effect the desired time delay in easing the ironing pressure. After the predetermined time, rod I45 has moved downwardly sufliciently for collar I53 to engage the valve tripping lever I52, and valve I56 relieves the pressure in pipe H2 and springs 59 and I9 lift the presser head II, which thus occurs after the predetermined lapse of time allowed for the pressing.

A different form of valve mechanism for holding the presser head pressure on the work and for releasing it is shown in Fig. 6. In this form a double-disc, spring-pressed valve I53, of the type previously described, is interposed between the constant pressure pipe III and the pipe I I2 which supplies the fluid pressure to the cylinders '58-" andt and from-"them tic presser head I'I. position in'front er the-operator, and means The pipe 92 to which pressure is admitted by the valve 2 9,- communicates with acylmder I I54, having a piston I55 which'is, impelled toward the top of the cylinder bya spring I56.-' The piston rod of piston- I55 carries at its end an interponent I51. A bell-crank lever I59 is pivoted at" I60, and one end of the lever is adaptedto coast the valve stem of valve I53, the other end of bell-crank lever I59 coacts with the piston rod I62 of a piston I63, which works acylinder I64, whicnacts as a holding device for valve I53. A pipe I65 communicates between valve I53 and the lower end of cylinder I54, and

the relief pipe II3 opens out of the bottom end of the cylinder. When-thevalve 29 is opened by the operator, to bring the Work Support to pressing position, the pressure inf-pipe 92 moves piston'l55 against its spring and moves-interponent I51 into position to be engaged by lug 89 when the work support comes to pressing position. This rocks bell-crank l'ever I59 and adhits the fluid pressure from pipe II'I into pipe H2 and puts the pressure on the head I I. When the operator releases valve 29 after thework support has swung over its center, spring I56 retracts interponent I57, so' that lug 89 no longer holds valve I53 open. However, when valve I53 is opened, the fluid pressure entered the bottom of cylinder ltd, forcing piston I63 upwardly, and piston rod i62 continues to hold valve I53 open through bell-crank lever- I59. Valve I53 will be held open, and thus maintain the pressure on head H, until the pressure is relievedpin pipe H3, at which time the spring in valve I53 will move the valve to cut off the pressure from head I- l- I and relieve pipe IIZ into pipe II 3, thereby permitting the springs 69 and 10 to lift the presser head II.
