Figure 15 is a schematic wiring diagram showing a control circuitfor the ironing machine.

Referring to the drawings and particularly to the general view of Figure 1 an ironer roll I0 is mounted for rotation, supported and driven from one end only, the end support being effected by means of a casting l2 and. a shaft ll supported at one end of the roll, the main body portion of the casting I2 is supported upon a table l3. A to!) portion M of the casting l2 extends forward to support the shaft I I. An electricallyheated metallic shoe 8 having heating elements 9 s positioned to contact the roll ID at the bottom thereof. as shown in Figure 2, and adjacent the shoe there is provided a table I; the heating eler ents 9. and the underside of the shoe 8 and table I being enclosed by a cover member 1 The shoe 8 is supported on a lever support mechanism embodying the principles of .a parallel linkage system. This' mechanism moves the shoe 8 toward and from the roll I8 from the ironing position shown in Figure 2 to the inoperative or normal down position shown in Figure 3 and also allows the shoe 8 to be retracted to a secondary, or safety position, shown in Figures 4 and 5, all as will be explained later.

The oscillating motion of a shaft 66 is for the purpose of actuating the heated metallic shoe 8 of the ironing machine into and out of contact with the under side of the roll I8 (see Figures 2 and 3) through a system of links and levers which will now be described. It is assumed for the purpose of this description that the shaft 66 is oscillated at the will of the operator by mechanism and controls later to be described and also that the roll I8 is rotated in a counter-clockwise direction as viewed in Figure 1.

In the ironing position with the shoe 8 in contact with the roll I8, as shown in Figure 2, the heated metallic shoe 8 is positioned directly under the roll I'8. The shoe 8 is moved into and out of ironing position by a lever 86 in combination with two support links or levers 88 and 98, the lower end of the lever 88 being broken away in Figure 2 so that the lower end of the lever 98 is visible, while all three levers can be seen in Figures 1 and 14. The links 88 and 88 are enclosed at the front thereof and above the table I3 in an ornamental shield K, which may be secured to said links in any suitable manner. The shoe 8 has a bracket 8 connected thereto at a point substantially medially of the length thereof and Ill the top floating pivot I88 of links 88 and 88 is rearward of the bottom fixed pivot 81 thereof when the parts are in the normal down or ironing position of Figures 3 and 2, respectively, thus requiring a definite forward pull of the table 1 and shoe 8 to swing the assembly to the safety position of Figure 4.

The main support for the shoe 8 is from the spaced links 88 and 98 the top pivot I83 of which is secured to the ends of the bracket extensions I82, which extend toward the operator from the medial region of the shoe 8 under the table 1. The lever 86 connects directly under the shoe 9 at the pivot pin 86 and its upper end cooperates with the upper ends of links 88 and 98 to complete a triangular support for the shoe 8, the lever 88 being actuatable (as explained later) for impartlng movement, while the relatively fixed support for normal operation is afforded by the links 88 and 98 through the bracket extensions I82.

I In order that the shoe 8 may be moved directly to the safety position shown in Figure 4 from the position in contact with the roll I8 shown in Figure 2, the lever device 9| previously mentioned, is made up of two parts, a pair of spaced links 92 connected at one end thereof to the lever 88 by the pin 91, and the rigid arm 94, the links 92 being connected by a pivot pin 93 to the arm 84, the

. links 92 having freedom of tilt at pivot 83 near the upper end of the lever 86 is pivotally com I nected to said bracket by a pin 86. Extension brackets I82 extend forwardly from the shoe 8 and carry a rod I83 which provides a floating pivot connection for the shoe 8 with the upper ends of the links 88 and 98. Each of the links 88 and 98 includes a forwardly extending offset portion which is pivotally mounted on a rod 81 carried by a bracket 88 fixed to the underside of the table I3. The actuating connection from the oscillating shaft 66 to the end of the lever 88 is a lever device generally identical as 8| and being shown in Figures 1 and 2, the lower end of the lever 88 being connected with said lever device by a pivot pin 91.

When the shoe 8 is in the inoperative normal down position of Figure 3, the entire assembly of the shoe 8 and table I floats and may be manually swung forward or toward the left, as viewed in Figure 3, by the hand of the operator to-a safety position such as shown in Figure 4, the position and form of levers 86, links 98 and 88 and their pivots 86--81 and 81-483 allowing such movement. This position places the shoe 8 approximately four inches away from the outer periphery of the ironing roll I8 and is intended primarily as a safety position complying with all requirements for such safety movement of a shoe away from an ironing roll. However, this position of the shoe 8 may alse be used to arrange articles for pressing or ironing as will be discussed more fully hereinafter.

In the normal down position of Figure 3 as well as in the raised position of Figure 2 the center of weight of the shoe and table 1 is so positioned that gravity will normally hold the shoe 8 in the normal down position of Figure 3 with lever 86 against stop I M on the end of a rigid arm 94, and it requires only a manual movement by the operator to move the shoe 8 and table 1 from the safety position of Figure 3 to the position of Figure 4. In carrying out this idea it is noted that shaft 66 and the arm 94 being rigidly connected to the shaft 66. The links 92 have a latch member 86 disposed therebetween and pivoted at its end on the pin 91, the member 96 being so positioned and formed as to provide a curved camming surface 98 which, when in the position shown in Figure 2, will effectively lock the members 92 and 94 together by contact of the camming surface 98 with a pin 99 in the free end of the rigid arm 94. Inasmuch as the members 92 are directly connected to the end of lever 86 the connected position of the latch member 86 will cause the oscillation of the shaft 66 to move the ironing shoe 8 upward and downward into and out of operative position with the roll I8. However, when the latch member 96 is pulled out of its interlocked position inter-connecting the members 92 and 94, as by the pulling of a member I88 by a hook-up later described which is connected to latch member 86, then even though the lever 86 be in a position to hold the shoe 8 in ironing position, such action of releasing the latch 96 will allow the shoe 8 to drop down into the inoperative normal down position equivalent to Figure 3 with the links 92 resting upon a limiting stop S, from which position said shoe can be manually swung to the position of Figure 5.

An arcuate spring is mounted at its lower end upon a pin 95 carried by lugs 92 depending from the links 92. The upper endof the spring 95 is received in a recess 96 formed in the latch member 96. The spring 95 normally urges the latch 96 toward an unlocked position after movement has begun and assists re-engagement of the parts 96 and 99 when brought toward engagement.

The interior of the casting I2 carries mechanism for controlling the drive to the roll I8 and shoe 8. Power for the drive is brought in from a belt I5 (Figure 1) from a motor M which is located below the casting I2 but not shown in the drawings, except diagrammatically in Figure 15. The

belt I5 drives pulley I6 and a worm I8 which is mounted to rotate with a shaft 28 (Figure '7). The worm I8 drives a worm wheel 2| which rotates on a, shaft 23 having one end thereof fixed in a boss |2 formed on the inner surface of the casting 2. Also mounted on the shaft 28 and normally free to rotate relative thereto. is a circular, shoe actuating cam 22. shown in Figure 1 as well as in Figures 6, '7, 10, 11, and 12 and as shown is eccentrically positioned on the end of the shaft 23. The previously mentioned worm wheel 2| has a hub portion 24 (Figure which extends a distance along the shaft 28 toward the cam 22 and has secured thereto a notched clutch member 26 provided in its outer periphery with a plurality of notches 26. A sprocket wheel 26 for driving the roll i8 is secured upon the hub portion 24 of the worm wheel 2| in such manner as to be free to slide axially and to rotate relatively to the hub portion 24 of the worm gear 2|. A-sprlng 38 normally urges the sprocket member 28 toward the left as viewed in Figure 10 and proje ing lug members 32 attached to a flange 34 on the hub of sprocket 28 are pushed into engagement with the notches 26 in member 26 thus normally causing the sprocket 28 to rotate with the worm wheel 2|. However, the flange 84 provided on the hub of the sprocket 26 is engageable by a shifter fork 86, which is pivotally mounted on a bracket 31 by a pin 81. The

bracket 31 is fastened to a stationary part 31 of the casting l2 by screws 81. When the shifter fork 86 is actuated it will push in opposition to the flange 84 against the action of the spring 86 and disengage and/or hold the lugs 82 out of engagement with the clutch member 26 so that the rota tion of the sprocket wheel 28 will be interrupted. This action of the shifter fork 86 is rendered. in

proper sequence relative to the rotation of the shoe actuating cam 22 by means of a cam 38 positioned on the side of the cam 22 which contacts a projection 48 on the shifter fork 86 and is so designed as to shape that it will actuate said shifter fork at the desired time in relation to the rotation of the cam 22. The shoe actuating cam 22 is connected to be rotated by a bowed clutch member 42 mounted on the inner side of the cam 22 and secured to said cam by a spring mounting (described later) allowing tilting movement of said member 42 but normally urging it to a position shown in Figure 10 with its projecting end 42A extending into one of the slots 26 of the clutch member 26, thereby connecting the cam 22 for rotation with the worm gear 2|. The clutch member 42 is mounted upon two projecting pins 4| and 43 (Figures 6 and 8) on the inner face of the cam 22 upon which pins the clutch member 42 is loosely mounted for tilting movement onits bent central portion the axis of tilt being indicated by dotted line X-X of Figure 8. The portion below dotted line X--X is normally urged against the face of cam 22 by springs A and 43A, respectively, mounted on the pins 4| and 43, tilting being allowed by a loose fit provided by oversize holes in the clutch member 42 through which the pins 4| and 43 extend. Such position normally holds clutch member 42 and its pro- The cam 22 is jecting end 42A in the connected position with clutch member 26, as shown in Figure 10, for rotating cam 22 as previously mentioned.

A projecting portion 44 of the member 42 is used to actuate said member to pull it out from rotating engagement with member 26 against its normal spring action. This movement is effected by contact with a cam lever 46 of substantially halfmoon shape (Figures '7, 8, 12 and 13). Cam lever 46 is mounted upon a pivot 48 secured to a boss 48 in the casting I2 and one of its ends 58 is adapted to be moved clockwise by a solenoid 5 2 6 through a link 58, and to be moved counter clockwise by a torsion spring 48A. Counter-clockwise movement of the cam lever 46 is limited by an adjustable stop screw 46 mounted in a lug 41 carried by the cam lever 46 and engageable with a wall of the casting l2. As the parts are shown in Figure 7, the projecting portion 44 is engaged with the cam lever 46 and the projection 42A of the clutch member 42 is held up and away from operative contact with the clutch member 26 and, therefore, will not be in a position to cause any rotation of the cam 22. However, upon energization of the solenoid 52 the end 58 of the cam lever 46 will be pulled away from the projection 44 (Figure 8) and the lever 42 will be allowed by its natural curvature and the action of springs MA and 48A to swing into the position shown in Fig-. ure 10, that is, into a position with the projection 42A engaged in one of the notches 26 in the member 26. A rotation of the member 42 in a counter-clockwise direction will result (compare position of Figure 8 to position of Figure 13) until the projection 44 contacts a stop 56 on the opposite end 54 of the member 46' (see Figure 13) which member is so shaped and inclined as to form a cam surface to catch the member 44 and by cam action tilt the clutch member 42 and pull the projection 42A out of engagement with the clutch member 26. The member 42 and cam 22 then come to rest with projection 56 engaged by the member 44 (Figure 13). It is apparent from the foregoing description that a half revolution of the cam 22 has thus been effected by the actuation of the solenoid 52 and as long as the solenoid 52 is energized the position of the parts will be that shown in Figures 11 and 13. Referring to Figures 6 and 11 a. return spring 58 is connected at one end by a pin 58 to the cam 22 and its opposite end is connected to a pin extension 68 of the pivot 48. The spring 58 is so located as to exert a counterclockwise pull on cam 22 when the pin 59 assumes a position below a line passing through the center of the pin 60 and the axis of the shaft 23; as in Figure 11, and tending to rotate said cam to the position shown in Figure 13, it being apparent that such counter-clockwise rotation is prevented by the aforesaid contact of member 44 with the stop or projection 56 which forms a latch. However, if the solenoid 52 is de-energized, the result will be that the lever 46 will tilt on the pivot 48 in a counter-clockwise direction as 'urged by spring 48A, thereby effecting movement of the stop 56 out of the path of the member 44 and allowing the cam 22 and the member 42 to continue their rotation, although such rotation is not effected by contact of the clutch parts but solely by the action of the return spring 58 (Figures 6, '7, 11, and 12). Thus, whenever the cam 22 is in the arrested position determined by the stop member 56 as shown in Figures 11 and 13 the return spring 58 will exert a pull in a direction to return the cam 22 and associated parts to their original position shown in Figures 6 and 8.

Referring to Figure 6 the cam 22 acts against a cam follower 62 and actuates a lever comprising two spaced members 64. and it will be evident on inspection of Figure 6 that the rotation of the cam 22 will oscillate the lever 64 and therefore osc llate the shaft 66 for shoe actuation as previously mentioned, the position of the parts in Figure '11 corresponding to the ironing position of the shoe 8 shown in Figure 2. The lever64 and the shaft 66 can also be seen in the general view of Figure 1. Acompression spring 65 is interposed between the oppositely extending end 02 7 lever 84 (mounted to swing on the shaft 88) and the free end of an arm 81 which extends out from shaft 58 and is secured thereto, the spring 55 being secured to the arm 61 by a pivotally mounted bolt 80. (See Figures 6, 7, 11, and 12). The

. spring 85 thus arranged provides a yieldable operating connection between the cam 22 and the shaft 58, and allows the shoe 8 to move away from the roll I slightly to accommodate different thicknesses of the clothes to be ironed or pressed.

Referring to Figure 1 the sprocket 28 drives a chain 58 and a sprocket 10 which sprocket is on a common shaft H with a pair of sprockets 12 and 14 near the top of the head casting I2, the sprocket 12 being of larger diameter than the sprocket 14 to provide two speeds for driving the roll I0, as is set forth hereinafter. The two sprockets 12 and 14 respectively drive two sprockets 15 and 18 freely mounted on a shaft 80 through chains 11 and 19, respectively, and said sprockets 15 or 18 may be selectively coupled to said shaft 00 through a conventional clutch member 80 free to slide axially but rotatably coupled to said shaft. The actuating lever 82 of such clutch member 80 is shown at the top of the head casting I2 in Figure 1. The shaft 80 has a suitable gear 80 connected to the end thereof and meshing with an internal gear 80 carried by the roll I0, said gears being shown schematically in dotand-dash lines in Figure 2. The several sprockets 1215 and 'I4--'I8 of the chain drive from the sprocket 28 to the shaft I10 are so selected as to provide two different speeds of rotation for the roll I0, depending upon the manual selection afforded by the lever 82.

As shown in Figure 1, there is a main control lever including a handle I20 having an end thereof projecting substantially over the top of the roll I0 and a vertical portion or shaft I22 extending vertically downward through the casting I2 to a position under the table top I3. The shaft I22 is suitably supported in bearings (not shown) and is adapted to be rotated by the projecting handle I20, and as viewed inFigure 14, a cam plate I24 is secured to the bottom of the shaft I22 and has a series of notches I26 marked as follows:

Release Heat Heat and Motor Motor Release A spring clip I28 is stationariiy mounted to engage the notches I26 so that upon rotation of the shaft I22 the lever will successively locate itself in the seven positions above listed when such positions are effected by manual movement of the handle I20 above the top of the roll I0. By electrical switch connections in a conventional switch IZI, not shown in detail, the positions Off, Heat and Motor are so connected by com action of plate I24 as to effect actuation of the heating elements in the shoe 8 and to complete the circuit to the motor. However, with the lever I20 in either of its maximum positions marked Release, levers I30 and I32 are brought into play to tilt the lever I34 which movement will pull the previously mentioned release member I00 to release the shoe-actuating mechanism. Such release, however, will only be necessary when the shoe 8 is in the upper or ironing position as in the other positions of said shoe, it can be pulled to its safety release position without such actuation. It is to be noted that the release of the shoe can be effected 8 by movement of the lever I20 to its maximum position in either direction.

As shown on the drawings, Figures 1 and 14, the normal actuation of the ironing shoe 8 and table assembly '1 upward and downward toward and from the roll I0 is eflected by a right kneecontrol device which comprises a lever I40 pivoted at I42 and positioned to actuate a conventional switch I44. Switch I44 is so constructed that one push of the lever I40 against it will close the electrical circuit to the solenoid 52 thereby actuating the solenoid to cause the shoe 8 to move into contact with the roll III. The circuit will remain closed until 9, subsequent movement of the knee lever I40 in the same direction again actuates the 'switch I44 to open the circuit and cause solenoid 52 to be de-energized and the shoe 8 will be moved away from the roll I0 by spring 58 and gravity as previously mentioned.

For controlling the pressing of clothes, 9. left knee lever control I50 is used, which is pivoted at I5I and operates a switch I52 connected in parallel with switch I44 but of a conventional type which closes the circuit only when held in closed position so that left knee actuation of lever I50 will energize'solenoid 52, and release of lever I50 will de-energize solenoid 52. The manner in which the switches I44 and I52 may be arranged in an electrical circuit with a motor M, the switch 2| and the solenoid 52, is shown diagrammatically in Figure 15, in which a main conductor A is con nected to one terminal of the solenoid 52 and has the switch I2I connected therein. The motor M is connected with the conductor A and a main conductor B. The other terminal of the solenoid 52 is connected with one end of a, wire C having the switch I44 connected therein, the other end of the wire C being connected with the conductor B. A wire D is arranged in parallel with the wire C and has the switch I52 connected therein. The heating elements 9 may be connected with the conductors A and B. Thus, it will be apparent that whenever the switch I2 I is actuated through the handle I20 and shaft I22 to interrupt a supply of current to the motor M, the circuit to the heating means 9 will be interrupted and also that the circuit to the solenoid 52 will be interrupted so that said solenoid will be de-energized. It will be further noted that the switch I52 is arranged in the circuit in parallel with the switch I44. The lever I50, in addition to actuating the switch I52, is also adapted to interrupt the driving of the roll I0. Thus, the lever I50 is connected to one end of a wire I54 and the other end of said wire is connected to a lever I55 pivotally mounted on a pin I51. A rod I59 (Figures '1 and 12) connects the lever I56 with the shifter fork 35.. Accordingly, when the lever I50 is actuated to exert a pull on the wire I54, the shifter fork will hold the roll sprocket clutch part 32 out of engagement with the clutch part 20, thus preventing a drive from being transmitted to the roll I0.

Starting with the shoe 8 in normal down position of Figure 3 the actuation of left knee pressing control I50 will result in energizing solenoid 52 by closing of switch I 52 and bring the shoe into contact with the roll I0 which is then stationary. However, if right knee control I has first been actuated to bring the shoe 8 up to the roll I0 while said roll is rotating, then the actuation of left knee control I will simply serve to disengage the clutch 2532 and stop the rotation of the roll l0, since the closing of switch I52 in the parallel circuit already closed will have no effect upon the completed circuit. However, when knee pressure-is released on lever I68 the clutch parts 26-42 will re-energize and the rotation of the roll l8 will continue. Such momentary stopping of the roll rotation gives added ironing and evaporating time when desired and provides means to stop the roll ill with the shoe 8 up when desired for any reason.

The thermostats for regulating the shoe heating element 9 are positioned underneath the shoe 8, one of the thermostats at the right hand end being shown at I88 in Figure 1. The control members for the thermostat I88 extend into and underthe table portion 1 and terminate in an indicator dial II8. Two of these indicator dials and thermostats are provided as shown in Figure 1, one to control the heat for each end of the shoe 8. An opening H2 in the top of the table I with suitable transparent covering II2 allows for inspection of the dial II8 while the opposite side of the dial extends downwardly into a lower opening H8 in the cover I. This projection of the dial H8 allows the dial H8 to be rotated for adjustment from the exterior of the cover 1 and the result of such adjustment maybe viewed at the top through the opening I I2. If desired, suitable illumination may be provided by a lamp bulb I I8 inside the table I for indicating the condition of the thermostat, varying colors and lettering being provided in the material of the dial III) which is preferably constructed of transparent plastic through which the illumination will be visible.

In the normal operation of the machine, the lever I28 will first be moved to the Heat position and then to the motor position and the ironing shoe 8 will be in its normal down position shown in Figure 3 in which the shoe 8 is away from the roll I8. As a result the worm wheel 2| and clutch member 26 will be continuously rotated by the motor and the shoe 8 will be heated. The material ready to be ironed is fed from the table '1 and when actual ironing operation is desired the right knee-control I48 is actuated, which will actuate switch I48 and energize the solenoid 52 shown in Figures 1, 6, and 11. Such actuation will move the end 58 of the lever 48 on its pivot 48 in an upward direction to allow release of the clutch member 42 because of removing support at 58 from under the projection 44 (Figure 8) and the projection 42A will then swing into engagement with one of the slots 26 in the clutch mem-v her 26 (Figure 10) and thus the cam 22 will be caused to rotate with the worm wheel 2| which has been continuously in rotation since the motor drive was started. The rotation of the cam 22 continues for a half revolution only, however, for

the reason that the projection 44 on the member 42 contacts the cam shaped end 88 of the lever 46 and tilts the member 42 so that the projection 42A is pulled out of engagement with clutch member 26 (Figures 12 and 13). Projection 44 also contacts stop 56 (Figure 13) and cam 22 is thus held in position by spring 58 (Figure 11) and stop 56 (Figure 13). The 180 rotation of the cam 22, that is, movement of said cam from the position indicated in Figures 1 and 6 to that of Figure 11, will, through its engagement with the roller '62, cause movement of the lever 68 and consequent movement of the shaft 66 in a direction to push the lever 86 in an upward direction thus swinging the shoe 8- from its retracted position (Figure 3) into ironing position under the roll as shown in Figure 2. As the cam 22 rotates, the cam 38 (Figures 7 and 12) attached to the inner side of cam 22 contacts a projection 48 on the shifter fork member 88 the camming action being so designed as to allow the lugs 82 to be urged into contact with the clutch member 26 by the spring 38 at the desired time and thus rotate the roll-driving sprocket 28 (Figure 10). The roll it is started in rotation, as controlled by the shape and position of cam 88, in time to have rotation begin prior to the time that the shoe 8 makes contact with the roll Ill. The necessary resilience for proper contact of the shoe 8 is assured by the yieldable or spring mounting 65 of the lever 84 relative to the shaft 66, as shown in Figure 6. When the ironing operation is completed, or if for any reason it is decided to stop the operation and contacting of the shoe 8 with the roll I8, the kneecontrol lever I48 is again actuated and such actuation will efiect opening of the switch I44 and deenergize the solenoid 52, the parts during operation just described having been in the position shown in Figure 13 with the member 44 in contact with the projection 56 with the parts held in position by the spring 58 of'Figure 11. By the aforementioned second actuation of the knee lever I48 the solenoid 52 is de-energized and the lever 46 (Figure 13) therefore swings in a counter-clockwise direction, as viewed in Figure'13, under the pressure of spring 48A and takes the holding support away from the projecting end of the member 44 which was effected by contact with the projection 56. The spring 58 when such release occurs then causes the assembly carried with the cam 22 to be rotated counter-clockwise for return to the position shown in Figure 6. The shoe 8 then drops away from the roll I8 by gravity to the position of Figure 3 with the links 82 resting upon the stop S, and the position of all parts correspond to the position of the shoe 8 away from the roll I8 from which position the mechanism originally started and the same cycle can be repeated at the will of the operator.

Variations in the above normal operation are possible including; the momentary stopping of the roll I0 after initial starting by actuation and holding of the left knee control I58; the pressing operation by actuation of the left knee control B88 from the normal down position of the shoe 8; and also the manual moving of the shoe 8 and table I to the safety position of Figure 4, from the normal down position of Figure 3, to arrange the articles to be ironed thereon, and again swinging the shoe 8 and table I into position for starting of either the pressing or normal ironing operations. Considering the roll I8 and the shoe 8 in the position shown in Figure 2, that is, in ironing position, let it be assumed that for some reason it becomes necessary to efiect emergency release of the shoe 8 away from the roll I8 either because something has caught between the shoe 8 and the roll I8 or for other reasons. The operator in such event could actuate the knee-control I48 which would immediately open the switch I44 to de-energize the solenoid 52 and thereby drop the shoe 8 to the normal down position from which a manual pull backward toward the operator would swing the shoe 8 approximately four inches away from the roll in to the secondary or safety position shown in Figure 4. However, in case it is desired to do so, the emergency release lever I28 may be used. Whatever the position of this lever may be, a movement toward its maximum position in either direction will cause the vertical shaft I22 to be rotated to pull levers I38, I32, I34 and by such pull to also pull the member i88, thus releasing the latching mechanism shown in Figures 2 and 2A at the end of the lever 86 previously described. Such release will cause the lever 86 to drop to the'position shown in Figure 3, carrying with it the shoe 8 and a pull on the table I or the shoe 8 backward toward the operator will also cause the shoe 8 to move to its safety position, as shown in Figure 5, which will be approximately four inches away from the outer periphery of roll II).

It is also important to note that lever I20,

. which actuates shaft in associated with switch III, affords a single lever control for heating elements 9, motor M'and release of shoe 8. The use of the main heat and motor control lever I20 as a release lever also makes use of natural instinct to seek the lever habitually used in case of'an emergency. The lever I20 is so arranged that movement of it in either direction will produce emergency release of the shoe 8. the movement of lever I20 to the release positions, or to any of the of]? positions also cuts oil the electrical circuit it will release the shoe 8 from its contact with the roll l and thus not only prevent leaving a hot shoe 8 in contact with the roll 10 but will also normally release both mechanically and electrically since it effects both de-energization of the solenoid 52 and the release of the latch connection 96; both of which drop the shoe 8 away from the roll "I.
