Application filed m 9, 1924; Serial No. 712,04 6.

This invention relates to pressing machines having coacting, pressing'elements, and a work conveyor for carrying the work between said elements when the press is 5 open, and out of between'said elements when the press is open or while the press is opening, after each closing operation, and has for its object a particularlysimple and efficient actuating and controlling means for 1 the movable pressing eleinent or head andthe work conveyor, whereby they movedn proper sequence, and more particularly whereby the conveyor shifts during the opening and closing of thepress, but "does 1 not start until after the pressing elements are first initially separated and stops before the pressing elements are brought in complete pressing relation. 7 T

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

I have here illustrated my invention as adaptable to garment andlaundry pressing machines, such as are used in laundries,

clothing factories, knitting mills, etc;

Figure 10 is a diagrammatic view of the lever arm 15 to w manual or operator operated means for controlling the actuation of the movable press-- ing element or head and the conveyor from a constantly movable prime mover.

This pressing machine comprises, generally coacting pressing elements, one of which 1s movable toward and from the other, a

fwork conveyor arranged to carry the work "to and from between the pressing elements,

actuating means for the movable pressing element and for the conveyor when said elements are separated or are separating and when said elements are closing but not entirely closed, a driver common to both of the actuating means, and a single manual or operator operated means for controlling the actuation of the movable pressing element and the conveyor, that is, for. controllin the intermittent ---movement of the driver y a constantly rotating prime mover or actuator.

I have here illustrated my invention as embodied in a garment and laundry pressing machine, in which the pressing elements comprise .a lower back '1, a press head 2 movable toward and from the buck 1, the buck being mounted upon a bracket or a bolstar-Y3 which in turn is mounted upon a main frame 4. All of these parts may be of any suitable size and construction. The

,main. frame 4 as here shown, comprises a table "carried by pedestals or legs 5, the

bracket or bolster 3 beingmounted on the The press head may be actuated by various kinds of mechanisms, thathere shown including toggle links 10, 1 1, pivoted together at 12', the link 10 being pivoted at 13 to, the rear end of the yoke or lever 6,"and the link 11--being pivoted at 14 to-the base of the frame, and'havin a forwardly extending hich the power isapplie for closing and opening the press. I

The press head 2 is balanced or. partly balanced by a counter weight 16. When power is applied to the lever 15 to depress it the toggle links 10, 11 will be straightened and the press closedin'the position shown in Fig. 1, and when power is applied to the lever 15 to lift it the press-will be opened, all as will be understood by those skilled in the art.

The link 10 of the toggleis adjustable endwisely, that is, it is constructed to be lengthened andshortened in any well known manner, to adjust the pressure to the thickness of the work on the conveyor between the buck land the head 2. i

17 designates the conveyor which is usually a belt, arranged so that preferably one run only passes between the buck 1 and the head 2, the belt extending to opposite sides of the machine, the right hand portion or the discharge end of the frame being illustrated in Fig. 3.

The belt at its and runs over suitable rollers carried by the frame, A. The lower end of the belt 17 extends through a transverse passage 18 formed below the bracket or bolster 3, and the top portion of the frame Usually the top or table of the machine is formed with this transverse passage.

The primary actuator or prime mover is a constantly running shaft, and is usually the.

armature shaft or an extension of the armature shaft of an electric motor 19 supported by the frame 5 beneath the table thereof.

The motor shaft 20, as here illustrated has a worm 21 thereon, which meshes with the worm gear 22 rotatably mounted on a shaft 2?)- thi: shaft 23when connected to the shaft 23.

The shaft 23 is the intermittently actuated driver for the toggle links of the pressing machineand also for the connections, to be presently described, between this shaft 23, and the conveyor belt 17. The shaft 23 is journalled in suitable bearings in a'casing 24, carried by the main frame, this shaft extending in a direction at a right angle of the motor shaft, and having an eccentric pin 25 at one end which is connected by a connecting rod 26 to the lever armlfi of the toggle link 11. One-half revolution of the shaft 23 causes the lever 15 to be depressed as shownv in Fig. 1, and close .the press. second halfrevolution as shown in Fig. 1, causes the toggle links to fold from straightened position and open the press. In the operation of the machine the shaft 23 makes a complete revolution starting with the press closed, that is, with the head 2 down (Fig. 1) hence on each intermittent rotation of the shaft 23, the head 2 opens and closes. During the opening; and closing of the head 2 the conveyor is shifted a predetermined distance.

The shaft 23 is connected at will to the shaft 20 or the driving gear 22 by, suitable means here shown as a clutch, manually shiftable or controlled in its shifting to in position and automatically shifted to out position. This clutch may be of any suitable form, size and construction and I have here illustrated it as a clutch of a modified form ofv the clutch disclosed in her.

the worm-gear 22 being the driver for Patent 1,569,420 granted. to Albert B. Glisson, Jan. 12, 1926. This clutch consists of a shifter or disk 28, slidable axiallyof the shaft 23 within the case 2 1, a guide disk 29 mounted on a shaft 23, clutch pins 3O movable in holes 31 in the guide disk 29,

the drive gear 22, and a main spring 36- tending to thrust the shifter disk to out position. The driver gear 22 is provided with a circular series of holes for receiving the pins 30, which are usually three in num- The shifter disk 28 is shifted in one direction. that is, to its inl position by an arm 37 mounted on a rock shaft 38 sup ported in the case 24, and thrusting against the hub of the disk 28'.

The rock shaft 38 is operated by a lever 4(), Fig, 1. Obviously, by moving the lever 40 tothe left, Fig. 1, the shifter disk 28 will be shifted to the left and cause the pins 30 to enter the holes in the driving gear 22. If the pins and holes in. the gear 22 are not in alinement the shif ting movement of the disk 28 will compress the springs 35, and I these springs thrust the pins into the holes 'in the gear 22, when they come into alinement, the ring 33 thrusting against the shoulders 3 on the pins.

The disk 28 is shifted into its in position by themanual or operator operated means.

As here shown, the movement of the clutch is so controlled by a cam ring 41, Fig. 4, 6 and 7 mounted concentric with the shaft 23 and having a high portion or track 43 and a notch 4-4, and the shifter ring 28 has a follower 451 movable along the ring 41, and into the notch. This ring is supported by the case 24': and is secured thereto as by screws 46. When the clutch disk 28 is shifted to the left Fig. i, by the lever 40, the follower 45 is in the notch 44 and is shiftedoutof the notch onto the track 43 and the clutch is held in during the complete opening and closing movement of the press head. tVhen,however, the press comes to closed position the follower 45 reaches the notch 4-4:. To open the press the operator merely momentarily presses the buttons or momentarilyoperates the controlling means and causes the clutch to be shifted in.

The means for operating the lever 4-0 may be of any suitable form, size and construction, that here shown is a' standard article of manufacture, as used on various types of operated or other operator operated means or parts.

The solenoid or the case thereof is supported by the frame 5, and includes windings 51, and a core 52 which is connected by a rod 53 to the lever 40 by a pin and slot connection 54. The lever 40 is angular as shown in Fig. 1. Obviousl when the coil 51 is energized the solenoi will be pulled down thus actuating the lever 40 and holdingit in actuated position as long as the solenoid is energized.

' The main clutch spring 36 acting on the lever 40 returns the solenoid to its operative position when the current is cut off through the windings 51, but an additional spring ma be used if desired.

Prefera ly the circuit through the windings of the solenoid is controlled by the switches or push buttons 55, 56. both of which must be depressed in order to close the press. These buttons are so located that both hands of the operator must be employed in closing the circuit through the solenoid.

This solenoid control for commercial presses is a standard article of manufacture, and its construction per se forms no part of this invention.

The connections between the intermittently actuated driver 23 and the conveyor comprises a timing or controlling mechanism whereby, assuming that the press is closed,

upon the operation of the lever 40 to open the press, the shaft 23 first acts to separate the pressing elements 1 and 2, and then actuates the conveyor to move it during the remaining of the opening movement of the press, and during the initial part of the closing movement of the press, and stops the conveyor during the final closing of the press, that is, the movement of the head 2, after. it has been brought down close to but not touching the belt or the articles thereon. Such connections, as here shown, include a shaft 55 journalled in suitable bearings 56 carried by the frame.

sup orting the conveyor, one end of the sha 55, being connected to one end of an intermediate shaft 57 by a universal joint 58, the other end of which intermediate shaft 57 is connected to the shaft 23 by a universal joint 59, and gears or motion transmitting means including timing or intermittent gearing, between the shaft 55 and the belt 17. This gearing includes a beveled gear 60 mounted onthe shaft 55*, and meshing with the beveled gear 61 mounted on a shaft 62 on which is also a mutilated gear 63 coactshaft 65 and the axle 68 of the roller.

ing with, a mutilated gear 64 mounted on a I shaft 65, whichfin turn is connected to the roller at one end of the belt by intermeshing gears 66, 67, mounted respectively on e multilated gear 63 is of a larger diameter than the mutilated gear 64and has a larger blank 63 than the blank 70 of the small gear 64, i

The mutilated gears are normally arranged as shown in Fig. 9, with the blank space of the small gear 64 normally extending centrally of the blank 'space v69 of the larger gear. These blankspaces are provided with indentations or center marks 71, 72, for facilitating the lining up of the gears.

The ratio of the gearing between the mutilated gear is such that" of a revolution of the mutilated gear 63 will produce an en tire revolution of the gear 64. pressing of the buttons 55, 56, assuming that the press head 2 is down in pressing position, the gear 63 is actuated to the right, Fig. v9, relatively to the gear 64.- until of the blank of the gear63 has been traversed when the teeth of the gears 63 and64 mesh. The movement over oneshalf of the blank of "the gear 63 permits the head 2 to travel far enough to free itself of the conveyor belt and the garments thereon. The head 2 then completes its upward movement and starts down on itsclosing movement and the belt is actuated a redetermined distancefas six feet, during the opening and closing movement of the press, but before the press head comes into engagement with the belt or thearticles thereon, the second or right hand half of the blank space of the gear 63 comes opposite the blank of the gear 64 which has made a complete revolution, so that, the gear Upon the j 63 makes a partial turnwithout actuating the gear 64 and the belt while the head 2 is being moved toifinal pressing position, and

the gear again comes to rest with the center indentation marks 71, 72, in alinement.

.To prevent overthrow of the belt, locking means are 'used, this locking means being actuated or controlled byf'the gear 63. This locking means comprises a latch or look 73, Fig. 8, here shown as pivoted at v74 to a frame member 75 and as pressed into enlltl gagement with the spaced apart shoulders 76, that is, into a notch on the rear face of the gear 64 by a spring thrustingfagainst a lock 73; and this. lock is pressed out of engagement withthe shoulders 76 just prior to the time the teeth of the gear 63-mesh with. the teeth of thegear 64; by means of an areshaped cam 79 mounted on the rear face of the gear 63 concentric with the axis thereof, and having an inclined end 80 which enters under the lock 73 just prior to the time that "the gear 63 startsto mesh with the gear 64,

slide 78 which inturn thrusts against the and this cam 79 holds the lock out of mesh While the belt is being actuated and permits the lock to again engage or drop off the rear end 81 of the cam as the indentation marks 71- and 72 come into alineinent.

This mechanism for controlling the actuation of the beltin a certain sequence or synchronisrn Withthe movement of the press head is particularly advantageous in that it is simple in constrnction,consists oi but few parts and is controlled by the operating .meens tor the presser machine mechanism.

neeeovi means for the conveyor connected to the driven shaft which is actuated by the driving shaft through the clutch, the actuating means :for the conveyor including timing mechanism to actuate the conveyor during the opening and closing only of the press head.

2. The pressing machine of claim 1 in which the mechanism between the driven shaft and the toggle is connected to one end of the driven shaft and the actuating means for the conveyor is connected to the other end of the driven shaft.

3. The pressing machine of claim 1 in which the actuating means -for the conveyor comprises a shaft connected to one end of the driven shaft and the timing mechanism of the actuating means includes intermittent gearing between the letter shaft and the convevor.

In testimony whereof, I have hereunto signed my name, atSyracnse, in the county of Onondaga, and in the State of "New York, this 28th day of Aprih 192 i.
