IBONING MACHINE.

Application med Haren e, 1926. serial No. 92,926.f

My invention relates to improvements in ironing machines, otherwise known as mangles, and relates more particularly to improvements in machines of thel class set forth in which the shoe or buck is xed, and wherein unobstructed access is had between one end of the roll, and the shoe or buck,

and the objects of my invention are: 1, ytoequalize or diierentiate the pressure of the roll against the shoe or buck.

2, to permit of the roll while still in gear, being moved through means under the control of the foot, away from the shoe or buck in order to facilitate the manipulation of the work. y f

3, to throw the roll completely out of gear to provide for ease of replacement of the covering.

4, to movably mount the feed board to permit the same to be moved out of the way when it is desired to iron such articles as skirts.

5, to simplify the construction of machines of thisclass by providing only one set of spring-controlled locking means which function to maintain the roll under pressure against the shoe or buck, and in the following specification `and the drawings forming partthereof, I shall describe and illustrate a disclosure within my invention, and what I claim as new will be set forth in the claims forming part of this specilication.

Fi 1 is an elevation of one end of the machlne, showing the roll spring-held against the shoe or buck, and Fig. 2 is an elevation of the other end of the machine, with the roll in the same position. Fig. 3 is. an elevation of the rear side of the machine. Fig. 4 is an elevation of the same fend of the 40. machine as shown in Fig. 1, but showingy the roll away from the shoe or buck and out of gear.

machine. Fig. 6 is a vertical longitudinal lsection on the line 6-,-6, Fig. 2. Fig. 7 is a horizontal section on the line 7-7, Fig'. 2.

, Fig. 8 is a horizontal, section on the line 8-8, Fig. 1, and Fig. 9 is 'a plan view of portion of the end of the machine shown in forfthe feed Fig. 5 is an elevation of one endy of the major portion of the front side of the' board out of normal position to permit free access between the end of the roll and the shoe or buck when ironing skirts, for example: this view shows the roll away from the shoe or buck.

In the drawings, like characters of reference refer to the same parts.

In using machines of this class, it is very important that both hands of the operator be available to manipulate the goods, while the roll is yieldingly held against the shoe or buck, and as will hereinafter appear, the spring-controlled means used to maintain the roll against the shoe or buck is bi-functional in character so that while the roll is still in 05 gear, it may be moved under the control of the foot suHiciently away from the shoe o1' buck to permit of the manipulation of the work, and without the necessity of having tostop the motive power for the machine.

The frame of the machine may be of any desired construction, and is conveniently illustrated in the form of standards 2 with which are preferably integrally formed cross pieces 3 and 4 which tie the upper ends of 75 the standards 2 together at different ends of the machine. 5 is the electric motor used preferably to drive this machine, though of course any suitable motive power may be used. This motor through the means of the belt 6 drives the shaft 7 through the medium of the pulley 8 thereof. The driving means just described may be enclosed in any suitable housing 9. The shaft 7 is housed within any suitable tubular member 10, and is providedy with a worm 11 mounted Within the boxing a, which worm meshes with the worm heel 12 mounted. on the stud 13, through the medium of the hub b of the pinion 14, also mounted on the stud 13. This pinion, in turn drives 'a gear wheel 15 which is keyed to the shaft 16. The stud 13 is held in the vertical plate c of the frame of the machine.

17 is an arm with which is integrally 95 formed the head 18, and it is through this head the shaft 16 passes. 'lhe head 18 extends well into the roll' 19, and for convenience of manufacture, this head is extended well towards the outer end ofthe roll 10 1is interposed between the tubular extension 20 and a housing 23, which housing is suitably fixed to the roll 19. 24 is a cap mounted on the outer end of the shaft 16, and suit-l ably secured thereto as by means of a set screw 25. The cap 24 is suitably coupled to the housing 23 by any suitable mea-ns such as a screw 26. By the means just described, movement is transmitted from the shaft 16 to the roll 19.

To provide bearing for the roll 19 adjacent the head 18 a housing and cap and antifriction means similar to those just described are ,provided and are collectively indicated at 2 "f The vertical 4plate c is slotted as shown at 28, and through this slot extends the outer end of the head 18. The located at the outer side o the plate o.

The vertical plate c' at one end of the machine, and a vertically-disposed plate d at the other end of the machine (see Figs. 2

' and 4) support the shoe or buck 29 which is conventionally shown. rThis shoe or buck is heated in any suitable manner, and since the means for this purpose forms no part of my invention, I have not illustrated the same.

Integrally formed with the lower end of the arm 17 and extending in the same direction as the roll 19 is a tubular extension 30,

and passing through this tubular extension is a rock-shaft 31 which is suitably coupled to said tubular extension as by means of a set screw 32.` This rock-shaft extends beyond each end of said tubular extension, and at one end of the machine it is journalled in a block 33, which block is mounted in aslot 34 formed in the cross iece .3: this construction supports this en of the rock-shaft 31. 35 is a pin which asses ear wheel 15 is.

a housing the inner side of which is slotted as shown at 39 and through which extends the outer end of the rock-shaft 31. This housing is substantially U-shaped in horizontal section, and the inner ends of the U are bolted to the cross piece 4 as shown at 40. The cross piece 4 is provided with an inwardly extending flange 41, and against this ange rests a coiled spring 42. The other end of this spring receives a boss 43 carried by the block 36, and isso kept in position. 44 is an adjusting screw threaded through the front wall of the housing 38, and adapted to be held in contact with the block 36. This screw may be, if desired, provided with a handle or lever 45 to manipulate the same. 46 is a nut mounted on the adjusting screw 44 and adapted to lock it in adjusted position, i desired.

l Vllntegrally formed with the tubular ex-` tension 30 are arms 47, and in the outer end oit each of these arms is pivoted a link rod 48. 49 is a treadle conveniently mounted in the lower portion of the standards 2. For exam le, the treadle may be mounted on a rock ar 50 which is conveniently held in the standards 2. This treadle is slotted as shown at 51 (see Fig. r1 where each link rod 48 passes therethrough, and these slots are of suflicient size, and the desir d sha e, to 'permit of the movement'of said trea le without binding against theflink rods 48,

the lower end of each of which is provided with a nut 52, or other` stop which' permits the treadle to be brought into engagement therewith to actuate the same.

' Carried by, or integrally formed with the arm 17, is an arm 53, the location of which may `be varied, though for convenience in construction this arm is located at that end of the machine supporting the driving gear. Extending through this arm is a rod` 54, the lower end of which is threaded and is provided with a nut 55 which normally rests in contact with the underside of the arm 53. The upper end of this rod 54 is threaded or other- `wlse fixedly associated with a jaw 56. In

this jaw is pivoted an arm 57 by means of the pin 58. The arm 57 is carried by a hub 59, which hub is secured by any suitable means such as a set screw 60 to the shaft 61 through ahole formed in the block 33 and Which has bearing in the arm 62 Carried by is tapped into the cross piece 3 at its upper end: the lower end of this pin is held in the cross piece 3. `The construction just -described, or its equivalent, rovides for horizontal movement of the tu ular extension 30 and the rock-shaft 31, for the pur se hereinafter more particularly explaine It will be seen upon reference particularly to Figs. 1 and 4, that the block 33 has clearance'with each end of the slot 34.

The outer end of the rock-shaft 31 is j ournalled in a block 36; which is mounted in the slot 37 formed in the cro piece 4. 38 is the vertical plate c (see Figs. 1 and 2). 63 is a lever mounted on the shaft 61 and suitably coupled thereto as by mea-ns of a set screw 64.-

lll() Mounted on thevrodj`l54' is a coiled spring l 65, and tension of this spring is regulated by the nut 66 threaded on the upper end of the rod 54.

While the parts, per se, just described are old in the art, still, as far as I know, the

prior art does not disclose this pressurecontrolling means in its simplicity, that is to say, two pressure-controlling means of the character described have heretofore been considered necessary in this type of machine, whereas I find I need-only use one unit.

Having now described the principal parts of my machine, I shall describe its operation.

As before-noted, any suitable type of mo-l tive power may be used to drive the roll, and in order to get the best results from a machine of this class, the operators both hands must be free to manipulate the work.

Before the work is to be operated on, the

` lever 63 is moved from the position shown in Fig. 4 into the position shown very clearly in Figs. 1 and 2 with the stop e in contact with the arm 62. 'Now since the arm 57 is coupled to the shaft 61, the movement of the lever 63 moves this arm in the direction indicated by the arrow in Fig. 4, and since the rod 54 is pivoted to the arm 57, this movement causes the rod 54 to slide through the arm 53. with result that the spring 65 is compressed, and motion is conveyed through the arm 17 to the head 18 (see Fig. 6) with the result that the roll 19 is brought into contact with the shoe or buck 29 (see'Fig. 2).

The roll 19 is locked in the position described from the fact that when the parts are in the position shown particularly in Figs. 1 and 2, a vertical line passing through the axis of the sha-ft- 61 will be nearer the machine than a vertical line passing through the pin 58, and the result is thatthe spring' 65 will, through the leverage provided for the arm 57 under the conditions noted. lock the lever 63 in the position shown in Figs. 1 and 2. The position of the parts just described will also yieldingly hold the roll 19.

through the medium of the arms 53 and 17 in contact with the shoe or buck 29.

The workis fed over the feed board 67 be- -tween the shoe or buck 29 and the roll, and

and the means to hold the roll yieldingly in position aga-inst the shoe or buck 29, is of course known in the art, but the means I employ to transmit motion from the lever 63 and spring 65 to the roll, is new.

Should the operator be required to adjust the work, this can be done without moving the lever 63. by pressing down upon the treadle 49. The treadle coming in contact with the nuts 52 will through the medium 0f the link rods 48 and arms 47 turn the tubular extension 30 on the rock-shaft 31: this movement will be transmitted through the arm 17 to the head 18, and result in the moving of the. roll 19 into the position shown by dotted lines in Fig. 2. While the parts described are in the dotted positions shown, the spring 65 of course is under greater compression than when it occupies the positions treadle 49, the spring 65 will expand and:

move the parts from dotted position shown in Fig. 2 into the position shown in full lines in this ligure. y 4

In moving the roll 19 away from theshoe or buck 29 under the conditions previously described, it is not necessary to stop the motive power, nor is it necessary that the pinion 14 be out of mesh with the gear wheel l5. The feed board 67 is of any convenient construction, and it is conveniently hinged as shown at 68 to the upper portion of the vertical plate c. The outer end is supported by a leg or support 69 which is hinged as shown at 70 to the table 71, which table is supported by the standards.

When the feed board 67 is moved into the dotted position shown in Fig. 3. the leg or support 69 drops down into the dotted position shown in this figure, and consequently unobstructed access is had to the outer end of the roll 19 and the Shoe or buck 29 (See vert-ical dotted position shown in Fig. 3, it is provided with any suitable counter-weight I When the lever 63 is in the position shown in Fig. 4, through the co-operation therewith of thearm 57. rod 54. arm tubular eX- tension 30, arm 17. and head 18. the roll 19,

is moved into the position shown in this ligure so that its gear wheel 15 will be out ot mesh with the pinion 14: the result is that although the motive power may be in action. the said roll may be rotated as desired in order to replace the cover, or for any other desired purpose.

The means shown to throw the roll 19 out of gear is very simple, yet positive in action. and is the same used to move the spring-held roll out of contact with the shoe or buck 29 when adiusting'the work. as shown in Fig. 2.

Obviously when the lever 63 is moved into the position shown in Fig'. 1` the gear wheel 15 isl brought into mesh with the pinionI 14.l The parts controlling the movements of the roll 19 throughout its length. substantial-l lv eoual distances towards and away from the shoe or buck 29. essentially move the axis ot this roll through a vertical plane. and I-f tically of the same length as the axis of the roll 1'9, thereby ensuring the proper lev-y erage. Since the block 36 may be moved inwardly in the slot 37 through the medium of the adjusting screw 44, such movement of this block/will move the rock-shaft 31, and cause the block 33 to move around the pin 35; this movement will be transmitted to the tubular extension 30, and through this extension and the arm 17 to the head 18, and through the tubular extension 20 to the outer end ofthe roll 19. When the desired pressure is provided at the outer end of said roll, the adjusting screw 44 may be locked in position.

During the described movement of. the block 36, the spring 42 is of course additionally compressed, and should it be desired to reduce the pressure of the outer end of said roll against the shoe or buck, when the adjusting screw 44 is retracted, the spring 42 will exertv pressure to move the block 36 outwardly" and, through the parts already clearly described` the outer end of the roll 19 will be moved away from said shoe or buck.

Anti-friction means will wear in time, and

if it were only because of this fact alone, the.

means l disclose, or the equivalent thereof, operating in the manner set forth, would be necessary in association with the roll 19 to produce a machineiof the class set forth of the highest eliciency: therefore it is selfevident that said adjusting means will be used to take up wear in the bearings, and also to increase or decrease the pressure of the outer end of the roll 19 against the shoe or buck, accordingly as the operator may desire. Y

But it must be understood that if this machine be used upon work of a uniform thickness, for all practical purposes, there would be no necessity of providing means to move the roll 19 through a horizontal plane, therefore l do not necessarily confine myself fto using such means.

While the movements described to be given to the outer end of the roll 19 areKappreciable, the movements of the inner ends of the shaft 16 and rock-shaft 31 are not suiiicient to interfere with the efficient co-operation of the gear Wheel 15 and pinion 14.

Furthermore since the treadle 49 is slotted Where the link rods pass therethrough, these link rods will not bind with the said treadle and interfere with the horizontal movement just described.

lf desired, l may provide the lever 63 with a shield 'f5/Which, when the parts are in the position shown in Fig. 1, would prevent access to the switch mechanism 76; this switch mechanism will only be uncovered fully -when the lever 63 is moved into the position shown in Fig. 4; this makes for safety in operation.

While I may use any source of heat forv the buck or shoe, in localities where electric current is available this is used to heat t-he buck. Some switch mechanism must be employed to control the current for this purpose. and in Figs. 1 and 3 I yshow a suitable switch, which embraces the casing ,80 suitably supported. This casing is provided with an outlet 81, and a switch 82. It is further provided with an opening covered with a piece of red glass 83 through which scribed and illustrated a specific embodiment f of my invention, I do not coniineemyself thereto and desire not to be limited/ in my scope of protection beyond the requirements sof the prlor art and the terms of my claims.
