Application ma December .28, 1923. Serial No. 683,151.

This invention relates to pressing machines as garment and laundry ressing machines, such as are used in c othing factories, tailor shops, knitting mills, laundries, etc., and it especially has for its object a particularly simple and efficient and durable and also pedalless mechanism by which the power, if applied when the press is open, is ineffective on the movable pressingelement or head, and by which the closing of the :press or the movement of the movable presslng element or head toward closed position a predetermined distance by hand isi'nefi'ective on the power mechanism, in other words the invention has for its object an arrangement of parts of a motion transmission mechanism whereby if the power mechanism is actuated when the press is'open, the motion thereof cannot be effectively applied or transmitted to the pressing element or head or whereby no motion can be elfectively' transmitted unless such head has been preliminarily brought .down toward the work by the operator or close to the work to a whic press being safety first position, before the power is connected.to' the former mechanism. By safet first position is meant a position in the operator cannot have his hands between the pressing elements.

The invention consists in the novel features and in the combinations and construc-' tions hereinafter set forth'and claimed.

In describing this invention, reference is had to the accompanying drawlngs in which like characters designate corresponding parts in "all the views.

Figure 6 is a detail seEtional view of the clutch for connecting and-disconnect ng the intermittently actuated cam to the motor driven shaft. p

"means tending Figures 7 and 8 are fragmentary views of modified forms of the toggle mechanism.

This pressing machine comprises, generally, coacting pressing elements, one movable toward and from the other, a carrier supporting the movable element, a power member, motiontransmitting connections between said member and the carrier, said connections including parts normally out of position to effectively transmit the motion of the power member to the carrier when the press is open and movable into position to effectively transmit the motion of the ual means as a handle on the carrier or the movable element to so move the movable. element into preliminary closed position and means including a-second handle for controlling the actuation of the power member. The power member is intermittently actuated'by means as an electric motor and the second handle controls the intermittent actuation of the power member.

1 and 2des-1gnate the pressing elements which are here shown as a so-called lower buck and an upper press head movable toward and from the buck, the buck 1 being usually stationary and carried by the bracket or so'-called goose neck 3 which in turn is mounted upon a table 4 suitably supported by a frame 5. i

The upper press head 2 is here shown as supported by a movable carrier as a lever or yoke 6 pivoted bet een its ends at 7 to a 1standard'8i extendin upwardly from the a suitable counterweight 1 0 and also usually has connected thereto a spring 11 acting in conjunction with the counterweight. The counterweight 10 and spring 11 constitute to open the press when no force is apphed or active. tending to close the press or hold'it closed. The handle 9 is a manual means for preliminarily closin the press against the counterweight 10 an spring 11 or other means tending to open the press, and for holding it closed until the power memberis actuated.

12 designates the power member which is here shown as a lever pivoted at 13 between its ends to the lower part of 'the frame near the floor, this power lever extending forwardly and rearwardly of the machine. The

power. lever-is actuated by an intermittently.

movable motor driven actuator as will be hereinafter described.

The connections between the power lever 12 and the carrier lever 6, are constructed to be inefi'ective to transmit the motion of the power lever 12; if actuated when the press head is up and 'also ineffective to transmit the motion of the carrier 6 to the lever. 12 when the press is being closed or the press head 2 is being moved a predetermined distance toward closed position by the operator.

These connections comprise links 14 and15' of the power lever 12 is efliective 0n the carrier 6. These connections further comprise means for preventing the toggle links from unfolding when the lever 12 is actuated and after the links 14 and 15 have been moved into or nearly into or toward the'dead center line of the toggle links 14 and 15 by such closing movement of the head 2.

The link 14 as here shown, is pivoted at 16 to the rear arm of the carrier lever 6 and the link 15 is pivoted at 17 to the rear arm of the power lever 12. The link 15 extends rearwardly from the power lever 12 when the press 1s open, and is movable into a position at or nearly at a right angle to the lever 12 when the head 2 has been pulled down by hand toward closed position a predetermined distance. The lost motion connection between the links 14 and 15 is of such a nature as to merely move the link 15 from its normal nearly horizontal position, Fig. 1, into a position approaching a right angle to the lever 12 when the head 2 is ulled down by the operator, so that the inks 14 and 15 idle during the closing of the press head 2 by the operator, or when the power lever 12 is actuated before the head is pulled down.

This lost motion connection is preferably a pin 18 provided on the lowerend of the link 14 and a lengthwise slot 19, in which the pin works in the link 15, the pin moving downwardly in the slot. and liftin the link into vertical position durin ownward mo ement of the press head by and, so that,

when the press head has been. closed a predetermined distance byhand the pin is at the lower end of the slot and hence, when the power is appliedto the lever 12, the link 15 or bottom of the slot 19 thrusts upwardly against the pin 18 and thrusts the link 14 endwise upwardly and forwardly and rocks the carrier lever 6 on its pivot to apply com paratively heavy pressure to the head 2. The bottom end wall of the slot 19 and the pin 18 constitute shoulders normally out of abutting relation and movable into abutting relation by the preliminary closing of the press head 2 by hand.

As the lever 15 is pivoted loosely at both of its ends and also as the lever 14 is pivoted loosely at both of its ends, means is pro- .vided for preventingthe unfolding of the links 14 and 15 at the pin and slot joint 18, 19 when the power is applied to the lever 12 after the press head 2 is closed or brought down by hand a predetermined distance. This means, as here shown, consists of a third link 20 pivoted idly or loosely at the lever 14 and to the frame and being arranged out of parallelism with both links 14 and 15 when they are in any position and particularly when they are in straight position or nearly straight position. The link 20, as here shown, is pivoted at 21 to the link 14 above the pin 18 and at its other end to the frame preferably coaxially with the power lever 12 or on the same pivot or shaft 13that the power lever is mounted on, although such link 20 may be differently arranged tojguide the links 14, 15 during the application of power to the power lever 12. The link' 20 being mounted on a different center from the link 15 which. causes its pivotal point 21 to move in an arc having a different curvature from the arc of movement of the pin 18L Obviously during the movement of the press head 2 downwardly by hand from the position shownin Fig. 1, toward that shown in Fig. 2, the links 14, 15 and 20 will move nearly into their position occupied in Fig. 2, and during such movement the pivot points 18 and 21 y will move in the arc mm and y-y respectivelyn As the links approach their posi- 11 tion shown in Fig. 2, the arc g having a greater forward and upward curvature than the are 00-60, obviously the pressure is applied through the act of the toggle consistmg of the links 14 and 20 and the link 15 tends to move the links- 14 and 20 toward the dead center line passing through the centers 13. As seen in Fig. 5, the link 20 is double and embraces the links 14, 15.

It is the movement of the links 14, 20 toward their dead center line or the movement of the pivot 21 in the arc y-y that applies the pressure to the head 2.0r carrier 6, and the toggle consisting of the links 14, 20 is actuated by the power lever 12 through "the 139 additional or second link 15 which is a thrust link pivotally or foldably connected to the power lever 12, and to one of the toggle links 14, 20, it being connectedto one of the partsto which it is connected by a lost motion, or pin and slot connection arranged to be taken up by the manual movement of the head 2 and the carrier 6 a predetermined distance toward closed position and the consequent movement of the links 14, 20.

If the power is applied to the lever 12 before the head 2 is brought down to a predetermined position, these connections consisting of the parts 14, 15 and 20, will at the most again move the head upwardly or open the press instead of closing it. r If the ower is applied to the lever 12, 'while the iiead is open practically no motion will be transferred to the head or at the most a slight oscillating movement. If desired", in

order to prevent the head from being ac- -gaged with the lever.

tuatedrat all from the power lever 12 until the head has been brought down to a predetermined position, the'rear side of the slot 19 may be omitted or the slot widened, as shown, in Fig. 7 or the lever 15 may normally stand in starting position, nearthe effective position thereof or inclined slightly out of vertical, as shown 1n Fig. 8, and be picked up ,by the link 14 when the head 2 has been pulled b hand a predetermined distance and move by the link 14.

The link 14 is adjustable endwise' to per 'head 14, and the'wheel turned in one direction or the other, the wheel is then again shifted downwardly so that the socket receives the head, and hence holds the wheel and the rod from turning.

The power lever 12 is preferably actuated in one directionby motor power, the appli-, cation of which is controlled by an'additional handle, which must be operated while the operator has hold of the handle 9, and as here shown, it is actuated from a con stantly running electric motor by an inter mittently movable cam, which is always en- The power lever is actuated in the other direction by a spring 12* which-carries the lever 12 to follow the cam. Y Y i 22 designates the cam which is carried 1 by a shaft 23, the cam being here shown as an eccentrically mounted pin having a roller 24 thereon, which en ages a wearing face 25 on the front end o the lever 12. The lever pressed is held against the roller to follow the same by the spring 142 This shaft 23 is journalled in suitable bearings 26 carried by a suitable casing .27 supported by'a bracket 28 carried by a frame member29, and is actuated intermittently one-half revolution by a; motor supported on the frame and having its shaft '31 or extension thereof provided with a -wor;n 32 meshing with a worm gear 33 mounted to rotate about the shaft 23- and to be connectedthereto and disconnected therefrom periodically by a half revolution or periodic clutch designated generally 34. This clutch is operated by a suitable hand lever 34 which is operated by the operator when the head 2 is brought down. If this leveris operated to throw the clutch before the head is brought down.

the cam makes a half revolution and actuates the leverf12 but the movement of the lever 12 is inefiective on the carrierlever 6 on account of the operation of the toggle links 14, 15-and 20, as before explained. However, the machine is now out of synchronism or seqlyice, as the power. lever ,12 is deand the. press is open while in V the pr per sequence the power depressed when the press is closed- In order to restore thesynchronism' or sequence it is necessary to again operate thelever- 34" to connect the clutch 34 tothe worm gear 33, so that the clutch in'making a half revolution will againrotate the cam 22 a half revolution. v

The clutch 34 maybe of any suitable form, size and construction and the construction thereof per-se forms no part of this invention. It is sufficient to bear in' mind that the clutch is operated by the operator to connect the ccnstantly running motor to the cam shaft 23 andis automatically disconnected when. the cam has made arhalf revolution.

The clutch here illustrated comprises an axially shiftable disk or carrier 35 having a hub 36 mounted to rotate about the shaft 23, a floating thrust ring 37 opposed to the disk 35, a guide 38 between the thrustring 3? and the worm gear 33, a plurality of plns 4O slidablein alined openings in the guide disk 38, thrust ring 37, and carrier disk 35, these pins having shoulders 41 against which the thrust ring 37 thrusts, one or more springs, as 42, tending to separate the thrust ring 37and the carrier disk 35, a main spring 43 tending to shift the ring 35 in one direction, as to the right, to dis connect the clutch, manual means for shifting the ring 35 to the left against the spring 43, and means for holding the carrier rlng 35 in itsimanually shifted position during the half revolution of the clutch. The gear wheel 33 is provided'with a circular series of holes 45 for receiving the pins 40 and thus locking the gear wheel 33 to the when the pins are registered with the holesguide ring 38 which guide ring is keyed to the shaft 23. As here illustrated, the gear wheel 33 is mounted on a hub 46 on one side of the guide ring 38 and the guide ring has another hub 47 on the other side thereof which is keyed to the shaft 23 as by a transverserkey 48. I

The means for shifting the clutch, as here shown, comprises a shifter or rock arm 49 mounted on a rock shaft 50 journalled in the casing 51 of the clutch, this rock shaft being operated to the left by the lever 34 and connections controlled by said lever. The arm 49 thrusts against one end of the hub 36 of the carrier ring 35 and when rocked in one direction serves to shift the carrier. to the left;'and. the carrier serves to shift the thrust ring 37 through the springs 42 to the left and thus move the pins in the openings into the gear wheel 33. In the event the pins 40 do not register with the holes 45, the springs 42 compress or yield and then,

45, react and thrust the pins 40 into the holes 45. Thus the lever 34 can be thrown to its full extent by the operator regardlessof whether or not the pins 40 are alined with the holes 45. I

The means for holding the ring in its shifted position until the clutch has made a half revolution comprises a' circular track 52 supported by the cover or the case 51 concentric with the shaft, 23 and having notches 56 preferably diametrically opposite each other for receiving the followers or rollers 57 on the carrier 35. Upon operating the shaft 50, the carrier 35 is thrust to the left carrying the rollers 57 out of the notches 56, so that the clutch now being engaged will start on its half revolution and the rollers will ride on the face of the ring 52 until the rollers again come into alinement with the notches 56 after the clutch has made a half revolution. When the clutch has completed its half revolution, that is, when the rollers have a ain come into alinement with the notches 56, the spring 43 thrusts the carrier 35 to the right to carry the rollers 57 into the notches 56.

The connections between the lever 34 and the rock shaft' for shifting the clutch 34, comprises an upwardly ez'rtending arm 58 on the rock shaft 50, a rock shaft 59 supported in a suitable bearing in the upper end of the frame 5 near the table 4, a rock arm 60 on such shaft 59, a pawl 61 pivoted at 62 to the rock arm 60 and having one end arranged to enga e the lever 58, the lever 34 being mounte upon the rock shaft 59, and a spring 63 tending to rock the shaft 59 in the direct on opposite to that by which it is rocked by the lever 34. Upon depression of the lever 34 the rock shaft 59 is rocked in one direction as to the right moving the rock arm 60 thereon to the right, causing the end of the pawl 61 to engage the upper end of the arm 58 and move such arm to the right and thus rock the shaft 50 to shift the shifter arm 49 to the left and hence shift the carrier ring 35 of the clutch 34 to the left to engage the clutch or shiftit to 'in position. The clutch is held in in position by the track 52 as heretofore described and when the lever 34 is released the spring 63 returns it and the shaft 59 to its-normal position. As the arm 60 swings in an arc upwardly away from the arm 58, the pawl in passing upwardlypasses out of engagement with the arm 58, this occurring after the clutch 34 has been thrown in. Duringretrograde movement of the shaft 59 and the lever 34', the pawl 61 slides over the upper end of the arm 58. Pivotal movement of the pawl 61 is'prevented whilethe pawl is operatingor thrusting against the arm 58, by a shoulder 64 on the arm 60 which shoulder engages the tail of the pawl 61. The arm 58 is inclined to the left and the weight thereof moves it to its normal position as soon as it is free of the pawl 61. However, the thrust of the hub 36 of the carrier ring 35 of the clutch 34 to the right by the main clutch spring 43 would also return this lever 58 to its normal position.

At an intermediate point between the positions occupied by the head 2 when it is open and the'position occupied when pulled down by hand to a predetermined position, the toggle mechanism, is at such a point for convenience called a neutral point, that if the power were applied from the lever 12 the head 2 and the lever 6 would be thrown upwardly with a more or less violent jar due to the toggle links 14, 15 and 20 unfolding backwardly, or the head might be thrown down by power.

In-other words there is an intermediate or neutral point which the head 2 and the lever 6 may occupy between open position and a predetermined closed position, where if the power were applied from the lever 12 the links 14, 15 and 20 would hesitate on account of the small leverage whether to unfold and open the press or to continue towar l straight position and close the press.

In order to prevent the application of the power at such intermediate or neutral point, means is provided for preventing the operating of the lever 34 until the press head has been pulled down by hand beyond such intermediate or neutral point. Such means would be unnecessary after the operator learned to pull down the head to such predetermined point. Such means comprises a lock operable to lock the handle 34 from operation when the press head and parts moved thereby are in such intermediate or neutral point. The lock comprises a rack 65 on a sector or arm- 66 mounted on the shaft 59 to rock therewith, and an endwise mov- 13,

ment of the lever 6 or some part movable with such lever as the toggle link 14, the rod 67 having a tooth 68 arranged to be moved into engagement with the rack 65 when the links 14 and 15 are at or near such intermediate or neut-ral'point. As here shown, the rod 67 is carried in suitable guides 69, carried by the frame and is pressed rearwardly so that its tooth 68 will engage the rack 65 by a spring 70 and is pressed out of engagement by a cam 71 on the link 14. This cam has high points 72 and 73, and intermediate low point 74 between the high points. The high points 72 and 73 press the rod forward to hold the tooth 68 out of engagement with the rack 65 when the press head is open and during its movement toward such intermediate point, and after the press head has passed such intermediate point; and the low point 74 of the cam permits the spring 70 to move the rod 67 endwise rear-wardly and hence engage the tooth 6.8 with the rack 65 when the head is in the neighborhood of intermediate point. Thus when the head is open, thelever 34 can be operated, and the cam 22 actuated to depress the lever 12, but the link 15 idles and very little or no move- Iiient will be transmitted to the press head. And when the press head is pulled way .down to a predetermined point and the lever. 34 is actuated, the motion of'the lever 12 will be effectively transferred to the press head '2 But if the operator neglects to pull the head down a predetermined distance, the operating lever 34" is locked so that the clutch 34 can not be thrown to cause the cam 22 to actuate the lever 12, the lever 34" locking when the head is pulled down to an interme: diate position, and not to .a predetermined or fully closed position, by the fact that the lock rod 67 is opposite the .low point 74 of the cam 71 and is-moved by the spring 70 to the right, Fig. 4, carrying the shoulder or tooth 68 into mesh with the rack or sector 66 .on the shaft 59 which is actuated by the lever 34*, and thus locks the shaft 59 from being rocked.

A. suitable buffer is provided for limiting the opening movement of the head. This buffer may be provided between the frame'lever 6 and-the main frame 5 near the pivot 7, of the lever 6, or to coactiwith any part movable with the lever 6. As here shown a buffer is provided on the interme diate part of the lever 20 and engages a stop surface on the rear arm of the power lever 12. i

75 designates thebufier on the lever 20 .and 76 a stop surface on the rear'end of the lever 12, the buffer 75 coming in contact with the stop surface 76 when the press is.

open, as shown in Fig. 1. However in the illustration of the toggle mechanism, shown in Figs. 7, and 8, t e buffer preferably located as at 77, between the forwardly extending arms 78' of the counterweight and the opposite surface of the standard 8.

In the operation of the machine, assuming that it-is in the position shown in Fig. 1, the operator places the garment 'or other article on the lower buck, takes hold of the handle and pulls downwardly thereon movthe head 2 toward the buck, so that, there is very little spacebetween thehead-and' the work on the lower back. Such movement carries the links 14, 15 and 20 from their, inactive position shown in Fig. 1 to near but not quite their effective positions shown in Fig. 2. The operator then -depresses the 80 lever 34 throwing in the clutch 34 and thereby connecting the motor to the cam shaft 23, whereby the cam 22 makes a half revolution to the position shown in Fig.2, thus depressing the lever 12 which in turn 'moves' the links 14, 15 and 20 into the posi 12 and holds the pressure as long as desired.

When the lever 34 is again operated to throw in the clutch 34, the clutch 34 makes another half revolution from the position in Fig. 2, to that shown in Fig. 1, permitting the spring 12? to pull the lever 12 upwardly and causing the,lever to follow the cam 22, and also permitting the counter weight 10 and spring 11, to open the press.

As the lever '12 follows the cam 22 during the opening of the press, the opening of'the press is controlled by the cam so that the press opens evenly and without jar or shock,

The pressis particularly advantageous in that it is pedalless and must be closed by one hand, to a safety first position before the power controlled by the other hand, can be effectively applied thereto, and in that it operates evenly as the actuating cam is constantly engaged with the power lever and no lock and latch, mechanisms are necessary to hold it preliminarily in safety first position or in final pressing position.
