DRIVING MECHANISM EOE IRONING MACHINES.

Application filed August 25, 1924. Serial No. 733,989.

' This invention relates to a novel driving mechanism for machines including, in com-,

bination an element having plural movements of translation, such, for instance as, a rotary and an oscillatory movement, together wit plural power means operable from a continuously driven rotor to operate the same, and including also a single manual manually operable control means to connect said rotor to the element to operate said element by power derived from said rotor in both its said plural movements, and the invention relates additionally to such mechanism hav ing means to control the power drive to said element in a manner to arrest one of said movements during continuance of its other movement.

My improvements are shown as adapted to operate the roll of an ironing machine of that type in which the work to be ironed, is pressed between a rotatable padded roll and the concave face of a heating shoe, the work being drawn therebetween by the tractive eiiort of said roll whose upper feed face moves towards the receiving side of said shoe. Said roll'is carried by swinging arms and is pressure held towards the shoe by power applied through said. arms. The roll driving mechanism is so constructed and controlled as to readily connect power to and disconnect it from the roll, and to also apply roll pressure to and relieve it from the work, so that the roll is under constant control to be rotated to perform its ironing functions,

" and to be released from and pressed towards the shoe by oscillating motion of its swinging support to facilitate adjustment on the work between the roll and shoe.

Among the objects of the invention, as applied to such an ironing machine, is to produce a roll driving and roll pressure mechanism which can be operated from a continuously rotatable shaft or rotor, and to be at all times under the ready and perfect control ofthe operator for adjustingthe work.

3 in the machine for connecting power to drive the rolland for quickly releasing and apply- 1 iug ironing .pressure, all separately and sequentially operative through power derived from the prime rotor;

, A further obj ectof the invention is to produce in a mechanism of this general character for imparting independent movements to an element (suchfor instance as a rotary and a lateral movement),'a controlwhich is arranged to be manually set in operation,

and is constructed to complete. its operation to sequentially give independent movements to said element and to disconnect said mechanism from power derived from a continuously driven rotor.

A further object of the invention is to produce, in a driving gear mechanism, including a normally continuously driven element or rotor and an intermittently driven element, novel power means, under initial manual control, to automatically connect by power means driving power to and to likewise disconnect driving power "from the intermittently driven element.

Another object of the invention is to produce a driving mechanism for an' ironing machine of the general'character shown, so constructed and adapted that the rotating and laterally movable element (theironing roll) is so connected and disconnected to power that said roll is connected to power and is rotating just before the roll pressure is applied to the shoe and, as a separate improvement, to cut off driving power from the roll just after the roll pressure is released so that thereby after such pressure release, the roll is free to rotate.

A further object of the invention is to provide a quick release mechanism, operable by hand or foot power to quickly release the rotatable element from a stationary element in the event power energy is cut ofl from the machine, as for instance if the feed circuit of an operating motor be opened.

A further. object of the invention is to produce a novel, manually tripped, power operated toggle connection for the pressing roll or analogus pressing element, constructed to maintain the roll or element yieldingly pressed against an abutment and to automatically and quickly apply'and release said pressure.

Other objects of the invention'are to otherwise improve, simplify and render positive driving and controlling mechanism of this general character, and the invention consists I in the elements and combination of elements with parts in sections, illustrating two posiing machine equipped with my improvements.

Figures 14 and 15 are detail elevations,

tions of a dog and its control which connects and disconnects power to and from the intermittently operative shaft of the driving mechanism.

Figure 16 is a perspective view of the parts illustrated in Figures 14- and 15.

The end frames 17 of the base of the ironing machine are connected by a back plate and also by tie elements 18,.'and the upper frame part of the machine comprises two end members 19 having rear upstanding standards 20 to support the. ironin shoe 21 to the upper ends of said arms by set screws which extends from end to end 0 the machine and has a forwardly facing concave ironing face.

The hollow ironing roll 22 is rotatably supported, through a central sleeve 23, on a fixed horizontal shaft 24 that is carried by the upper ends of swinging arms 25 which are pivoted at their lower ends to swing in vertical planes. Said shaft is fixed 26 extending obli uely through inward extensions or hubs 2 of said arms to impinge against said shaft 24 so as to cause the roll to be moved toward and away from the concave face of the shoe when the arms are swung on their pivots, in the manner hereinafter described. The roll is hollow at its Figure 9 is a detail front elevation at the end and formed as an internal gean 28 that meshes with a pinion 29 fast on a short shaft 30 that is rotatively'mounted in said inward extension or hub 27 of the roll supporting and pressure arm 25 and at its outer end carrying a gear 31 constituting the upper terminal gear of a driving train, hereinafter to be described, enclosed in the hollow or chambered arm 25.

34 designates a feed board over which thework is fed onto the roll and into the space between it and the ironing shoe, and the frame of said board is supported by'pivots 35 and upholding springs 36, which latter are sustained on said arms. Normally the feed board is disposed in a plane substantially tangent to that of the upper face of the roll. Said board affords means to support the work preparatory to introducing it between the roll and shoe, and its pivotal function about its pivots 35, against the action of the restoring springs 36, enables it to actuate the control for the roll driving and roll oscillating mechanisms in the manner hereinafter described.

The roll is driven through a train of transmission or driving gears 38, the shafts of which are mounted in the walls of one of the hollow arms, in accordance with the .arms 25 terminate in

hubs

40, 40, both of which are circumferentially faced to rockingly enga e internally cylindric bearings in the end ame pieces 19. The supporting and pressure arm hub 40, at the lower end of the right hand arm is internally mounted on a bushing 43 that is supported on arotatable countershaft 45 which rotates in said bushing 43 and a bushing 46 which is supported in a casing 47 that encloses the principal parts of the driving gear mechanism, as best shown in Figures 4 and'6, and is rigid with the frame.

Said countershaft 45 is driven through a driving shaft 50 that ,is belted to a motor 51 that is wall mounted'on the frame, the driving connections including a worm 52 on the countershaft and a worm gear 53 that is keyed to said countershaft. On the outer end of the countershaft 45 is a sleeve 54 that is threaded at its outer end to the reduced outer end of said shaft, the hand of the screw relatively to the direction of rotation of the shaft 45 being such as to normally hold the reduced, screwthreaded portion. Slidable on said sleeve 54 and splined thereto is aclutch collar 56, having on its inner end an annular series of clutch teeth 57 adapted to mesh with an annular series of clutch teeth 58 formed on the outer face of the gear 59 that meshes with the lower terminal gear 38 of the driving gear train hereinbefore referred to. When the clutch, thus produced is mated, the driving gear train and the roll is rotated by the motor 51; and driving power is disconnected at said clutch by endwise outward movement of the sleeve 56. The clutch collar is shifted on the sleeve 54 through the axial movement of a rotative shaft 60 having rotative and axial bearing in the end frame plate 19 and casing 47, said shaft having at one end beyond said frame plate a forked shifter finger 61 which engages in an annular ggoove of said clutch collar. Said shifter ger61 is loose on the shaft 60, permitting the latter to rotate therein, and it is confined between a shoulder on .said shaft and spring 64 that is interposedbet-ween one side of the finger and an opposing face in a knob 65 that is threaded to said shaft in the manner shown in Figure 6. Said spring 64 affords a loose or yielding connection between the

clutch teeth

57, 58 to permit them to go into mesh without clashing, both when the clutch collar 56 is operated by handthrough the knob 65 and when the clutch is operated by power.

The said shaft 60 is axially shiftable by power to control the clutch collar 56, and thereby connect the roll to and disconnect it from driving power, by means of a cam, designated as a whole by (Figure 13). Its beveled edge engages a grooved collar 80 fast on the shaft 60, and the lateral offset of the rotating cam, when rotating with the shaft '45, gives axial shifting movement to the clutch actuating shaft.

Said cam is herein shown as made, integral with an eccentric body 66 which is norm-ally loose on the shaft, but can be locked thereto by a dog and ratchet mechanism, under the control of a rocking cam 91, shown and hereinafter to, be described. The eccentric body is held from movement along the shaft 45 between the hub of the worm gear and a collar 67 keyed to the shaft 45'. i

The construction described provides means for transmitting driving power at a suitable speed from the motor 51 to the roll 22 throu h the trainv of gears in the hollow right land supportin and pressure arm 25. The roll 22 can thus e rotated through the shaft 45, the sleeve 54 and the clutch element on the clutch collar 56 and gear 59 throughout any desired duration, and during such rotation of the roll it is pressure-held towards the shoe. When the roll is thus being I turned the shaft 45 rotates freely in the eccentric body 66 and the rocking cam 91 and transmits'no movement to the latter, Said eccentric body is adapted, however, to be locked to the shaft 45 by a dog and ratchet mechanism, under the control of the rocking cam 91, in a manner hereinafter to be' 'is actuated to connect driving power to the roll.

The detail of the present embodiment of 'the structure for connecting power to and disconnecting power from the roll, and for operating the roll pressure and release means is made as follows:

68 designates an eccentric strap which encircles said ec'centric body, .66. It is connected to the front end of a rearwardly extending link 69 (Figures 4 and 5) that is pivoted at its rear end by a pin 69' to a crank arm 70 bf a rock shaft 67 which extends from end to end of the machine frame and is mounted to rock in bearings 19' in the upright members 20 of the frame members 19. At the ends of the machine, just inside of the end frame members 19 are rearwardly extending vertically swinging crank arms 71, the forward ends of WhlCh are apertured to fit over the hubs 40 of the roll supporting and pressure arms and are fixed thereto by keys backed by locking screws 71. The rear ends of said crank arms 71 are connected by yielding toggle connections tosaid rock shaft 67, the construction being such that when said shaft is rocked-on its axis the crank arms 71 are actuated to swing the roll supporting and pressure arms towards and from the ironing shoe once durin each rotation of the eccentric body 66. T e yielding function of the connection serves to resiliently press the roll toward the shoe.

Said yielding toggle connections comprise, in combination with crank arms 72 fixed to the shaft 67, pairs. of telescopic members 73, 74, respectively, pivoted at 75, 7 6'to said rock shaft crank arms 72 and to the rear ends of the crank arms 71, respectively, said element 73 being hollow to receive the element 74; and between a shoulder on the element 73. and a shoulder on the element 74, and surrounding the latter elements, is interposed a. spiral compression spring 77, the compression function of which is to yieldingly press the roll against or towards the connection to the hubs 40 of said arms made as follows:

through the keys and screws 71, the roll supporting and pressure arms are swung outwardly. The dash straight and curved lines on Figure 5 indicate the .positions of the arm 71, link 69 and the crank

arms

70 and 72 and the resilient toggle connection between the crank arm 71 and the rock shaft 67, which said parts occupy when the roll is being held up against the shoe.

Referring now to the means for connecting and disconnecting the continuously rotative shaft or rotor from the roll driving means and for connecting and disconnecting said shaft or rotor'to and from the roll pressure and pressure release means, the same is 82 designates a rock shaft which extends loosely through and has rocking motion in an opening in the eccentric body 66; said shaft and opening being parallel, and out of line, with the center of said eccentric body and on the side of the longer radius of said body from the shaft 45. 83 designates a dog which is carried'by one end of said rock shaft 82. Said dog is disposed between said cam 80 and the ratchet wheel 84 which is fast on the worm gear 53, surrounding the hub of said worm gear (Figure 4).

The shank of said dog is parallel to the face.

of said ratchet wheel and its tooth' 85 is laterally offset to engage the peripheral teeth of said ratchet wheel, as indicated in Figures 7, 13 and 16. This arrangement affords compact disposition of the parts along the axis of the shaft and enables the dog to be made rugged relatively to the space occupied thereby. The said dog 83 4 has a small angular lost motion connection to the shaft 82, as by means of a stud 86 threaded through the hub of the dog and engaging at its inner end a peripheral notch or recess 87 in the shaft (Figures 14 and 15). 85? designates a leaf spring which is supported by a clamp 80 carried by the cam 80, the free end of said spring bearing against the toothed ends of the dog in a manner tending to press the free end of the metrically disposed concentric walls 89, 90 of the before-mentioned rocking cam 91 mounted for limited rocking movement on the shaft 45. It is held from movement endwise alongsaid shaft between the collar 67, before mentioned, and the hub 40 of the right hand roll supporting and pressure arm (Figures 4 and 6). The track of said cam is disposed as two diametrically opposite

concentric portions

88, 88 and as two shorter diametrically opposite,

eccentric portions

88, 88.

The outer wall of said track 88 is not continuous, but is interrupted or open at points disposed diametrically across the axis of the cam. Said openings in the outer cam walls are bridged by the leaf springs 92 that are fastened to the free ends of the concentric parts of said outer wall. Each spring is directed obliquely inwardly across its associated wall opening and slightly overlaps the associated eccentric lip 93 of the outer wall and the corresponding eccentric inner wall 94 formed on the perimeter of the inner solid cam part or body.

96, 96 designate pins or abutments fixed to the cam 91. They are disposed transversely of said springs to bear on the outer faces thereof in such a way that the free ends of said springs may be sprung outwardly by the cam lug or roll 82 when the latter is moved along and inside said springs, and to thus tend to rock said cam on its axis in one direction against the action of a cam restoring spring, to be hereinafter described.

Said rocking cam 91 is provided with diametrically disposed

radial arms

98, 99. The

rear arm 98 extends backwardly through a slot 100 in the casing 47 and vibrates between limiting shoulders at the ends of said slot. .Said arm 98 is normally pulled downwardly by a tensile spring 101 fixed to said arm and anchored to a pin fast on said casing 47 as shown in Figures 5, 8 and 10. The front arm 99 likewise extends forwardly through aslot 102 in the casing wall to vibrate between limiting shoulders at the ends thereof.

103 designatesa latch arm that is located in front of casing 47 and is fast on a rock shaft 104 which is rockingly supported in hearings in the machine frame. The upper end of the latch has a down-turned hook 105 which lies in the path of a laterally directed lug or pin 106 fixed to the end of said arm 99 and is adapted in certain parts of the operating cycle to engage over said pin to hold the rocking cam 91 stationary against the action of the spring 101. When the cam '91 is thus held, it is normally stationary to permit the cam lug or roll 82 to travel through the cam slot thereof. A spring 108 unitarily assembled with the latch 103, in rear thereof, bearsagainst the casing 47 to normally hold the upper hook end 105 of the latch swung forwardly to the position indicated in full lines iii Figure 8 and in dotted lines in Figure 10, to be in the path of the pin 106, when the cam 91 is rocked to the position shown in dotted lines in Figure 11, and to be thereby in position to engage said pin 106 and to limit the restoring movement of said rocking cam under the action of the spring-101. The forward swin of the upper end of said latch is limited by an adjustable screw or abutment 110 which bears against said casing 47 below the shaft 104.

The latch is tripped from the pin 106 through the medium of a plunger 112 that is loosely connected at its upper end to the swinging feed board frame and is adapted to engage at its lower end the rear end of a crank arm 113 that is fast to and extends rearwardly from the rock shaft 104. When said latch is so tripped, the spring 101 rocks the cam 91 in a clockwise direction, as shown in Figure 12, the rocking movement of said cam being limited by engagement of the arm 98 with a shoulder 114 at the lower end of the slot 100, as shown in said Figure 12.

Operation.

When the parts are, in the positions indicated in Figure 2, the roll 22 is closed on the shoe and at this time the gear train clutch is closed and driving power is transmitted through the shaft 45 to the roll driving gear train. Said shaft 45 is also rotating freely through the eccentricbody 66 and the dog 83 is free from the ratchet 84. In the principal V/figures of the drawings, the mechanism is in its open position, or in the position in which the roll 22 is released from the ironing shoe and the shoe is disconnected from power to rotate it.

It may be stated here that when the cam roll 82 is occupying an eccentric portion of the track. at either side of the axis of rotation of the eccentric body 66, the dog 83 is disengaged from the ratchet wheel 84 because the said roll is shifted away from said axis and the tooth of said dog is shifted or raised away from said ratchet, so that no power will be transmitted from said ratchet to said eccentric body. So also when the cam roll 82 is occupying a concentric position at either side of the axis of rotation of said eccentric body, the tooth of said dog 83 lies against and engages the ratchet totransmit power from the ratchet to said eccentric body. In either the open or closed positions of the parts, the rocking cam is locked stationary by its latch 103, as shown in Figure 8, against the actionof the spring 101.

Assuming the machine to be open, tilting depression of the feed board 34 acts through the plunger 112 and rock arm 113 to release the latch from the cam arm 99, whereupon the spring 101 rocks the cam 91 in a clock wise direction and forces the adjacent concentric part 88 of the cam track over the cam roll 82 The rocking movement of the cam is limited by engagement of the arm 98 with the shoulder 114. This movement of the roll towards the axis of the cam 91 acts through the arm 82 to turn the'rock shaft 82 in a clockwise direction and to force the tooth of the dog 83 towards and against the ratchet wheel 84. 'Therefore, the eccentric body is temporarily locked to rotate with the shaft 45 and power is transmitted from the shaft 45 through the eccentric strap 68' and link 69 to rock the shaft 67' and thereby lower the rear ends of the crank arms 71 to swing the arms 25 rearwardly and thereby force the pressing roll 22 towards the shoe. Such rotation of the eccentric body also carries the cam roll through the concentric part 88 of the cam or from the posi-- tion shown in full lines to that shown in dotted lines in Figure 12. The yielding toggle between the shaft 67 and the arm 71 serves to firmly hold the roll 22 pressed towards the shoe until the eccentric body is again connected to the shaft or rotor, which occurs after a next succeeding tripping of the rocking cam 91.

The clutch shifting cam at the same time is actin'g on the shaft 60 to shift it endwise to close the gear train clutch (57 58) and the movement of the parts are so timed that the pressing roll, theretofore disconnected from the driving shaft or rotor 45, will be in rotation just before it is brought to pressure position against the work. This is a desirable feature because the work is at once, upon applied pressure, caused to pass between the roll and shoe.

The cam roll 82 after its travel through the concentric part of the cam track, is brought into engagement with the rising side ofthe inner wall of the next onward eccentric cam track portion 88' (see Figure 12), and forces the free end of the adjacent spring 92 outwardly, curving it about the pin 92, as shown in Figure 11. The fric-.

tion generated between said roll and the inner face of the cam track on one side and the spring on the other side, overcomes the tension of the rocking cam restoring spring 101 and rocks said cam 91 in a counter clockwise direction and swings the pin 106 of arm 99 past the hook of the latch 103. During this rocking movement of.the cam 91 and before it has reached the limit of its throw, the cam roll 82 passes the end of the spring 92, but has not passed fully into the next eccentric portion 88' of the cam track. Itiis at this time that the rock shaft 82 is rocked sufliciently to release the tooth of the dog 83 from the ratchet 84 to thereby disconnect the shaft or rotor from the ressure releasing means for the roll 22. fter the release of the c.am roll 82 from the spring 92, the spring 101 acts to rotate the cam 91 in a clockwise direction to permit said cam roll to pass fully into the eccentric portion 88 of the cam track, which will furtherswing the tooth of thedog 83 from the ratchet 84. The cam restoring movement will be arrested by engagement of the pin 106 with the latch hook 105. Thereafter, and until the latch 103 is again tripped, the cam roll will remain in the eccentric part of the track of the rocking cam 91 and the shaft or rotor 45 will rotate freely in the eccentric body and will continue to drive the pressing roll against the work (see dotted line of cam 91 in Figure 11).

When it isdesired to release the pressing roll from the shoe and to disconnect power from the gearqtrain, manual pressure is applied to tilt the feed board 34 and thereby release the latch 103 from the arm 99 of the rocking cam 91, in the manner shown in Figure 11, and at a timewhen said cam roll 82 is occupying a position in the eccentric part 88 of the cam track diametrically opposite to that shown in Figure 8. The spring 101, actin on the arm 98, will thereupon swing said arm downwardly and cause the cam 91 to rock in a clockwise directionuntil the parts are arrested by the limiting shoulder 114, or a correlative shoulder in the slot 102, as desired. This movement of the rocking cam shifts the next forward concentric part of the cam track over said cam roll,

'or a position just in advance of the "dotted line position of the rocking cam shown in Figure 11., Thereby said camroll 82 is swung inwardly to rock the shaft 82 in a clockwise direction to. cause the dog to engage the ratchet wheel 84 and thus rotate the eccentric body in a direction to release the pressing roll from the ironing shoe; The cam 80 also rotates with the eccentric body and its operation is in a direction to demesh the gear train clutch. The operation of said clutch occurs just after the pressing roll pressure is released, thus permitting the said roll to be turned freely by hand. During this time, the rocking cam remains in the position shown in Figure 12,

and the cam roll is passing through a con- 7 centric portion of the cam track to maintain driving connection between the ratchet 84 and the cam body 66. This drivin connection continues until engagement 0 the cam roll .82 with the next succeeding pin-backed s ring 92 rocks the cam 91 in a counter c ockwise direction against the action of the spring 101. The dog is then disconnected froin the ratchet wheel 84 at a time when the cam roll is climbing the rising side of the eccentric cam track part and just as the. roll passes away from said spring 92. The spring 101 thereupon restores the rockmg cam and shifts its eccentric part over can be yieldingly pressed towards and'released from the shoe once during each complete rotation of the countershaft 45 and that the roll may be held pressed against the shoe and rotated an indefinite number of turns, depending upon the length of work being ironed. The roll is rotated comparatively slowly, relatively to the speed of the shaft 45 which drives the same, due to the gear ratio between the pinion 29 and internal gear 28. It will also be observedthat the control for the roll driving and pressure and release mechanism can be manipulated by the same swinging movement of a single element and without change of the operator from a central operating position. It will also be observed, so far as is concerned the operation as thus far described, that said control mechanism is wholly power operated, after the initial manual operation of a single trip.

plied, and therefore power to the countershaft 45 be cut 011', manual means are provided for quickly releasing the roll pressure and thus prevent scorching the work. This can be effected, by providing the shaft with an elongated toothed pinion 116 to mesh with a late tric bo y 66 on the side thereon remote from the cam 80. This shaft can be rotated by hand power applied to the knob to turn the shaft 45 in the same direction as it is designed to be turned by power, whereby said eccentric body acts on the link 69 to break down the yielding toggle connection to the roll, and to permit the roll pressure to be released; and the cam also acts on the shaft v60 to break the clutch connection to the roll driving gear train. It is only necesgear 117 made fast to the eccen-- In the event the motor circuit should be I opened at a time when roll pressure is apt sary to withdraw the pressure roll slightly from the shoe in order to release the work and if full cycle of movement be not effected, it will be continued by power when the motor circuit is again closed. The lost motion between the do 83 and the shaft 82 permits the dog to yie d against the spring 85 and click over the ratchet wheel 84, which at this time isnot turning.
