Specification of Letters Patent. Patented Jan. 4, 1916,

Application filed .Tune 4, 1915. Serial No. 32,073.

To all whom it may concern: I

Be it known that I, CHARLES W. SADLER, a citizen of the United States of America, residing in \Vindsor Locks, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Ironing-Machines, of which the following is a specification.

' This invention relates to improvements in ironing machines and has for an object to provide improved means for ironing goods alternately on opposite sides several times, whereby the ironing is caused more nearly to approach the, work of a hand iron.

Another object is to provide yieldable means to force the goods against the ironing members, whereby goods with buttons may be ironed without breakage of the latter and part of the operator.

A further object is to provide a plurality of traveling tapes, axially spaced one from the other and means to force the tapes against the ironing chest with the goods therebetween, whereby goods of varying thickness placed side by side may be prop-. erly ironed, as one tape may yieldinde-.

pendently of another.

Another ob ect is to provlde in an ironing machine improved steam traps in the heat.-

ing system for the ironing members, which are arranged to insure equal heating 'of each member.

Another object is to provide in an ironing.

occupied and to generally improve and slmplify the structure.

WVith these objects in vlew, a slngle preferred embodiment of my invention is shown, for the purposes of illustration, in.

the accompanying drawings, in which:

Figure 1 is a front elevational View of the machine with certain parts broken away to reveal the driving mechanism; Fig. 2 is a sectional elevation taken longitudinally through the machine; Fig. 3 isa partial rear elevational View of the machine with certain parts broken away; Flg. 4 1s a d1agram matical view of the heating connections for the ironing chests; Fig. 5 is a partial sectional elevation on an enlarged scale showing clearly the arrangement of a single ironing chest and the pressure rolls therefor; Fig. 6 is a plan view of Fig. 5; Fig. 7'is a front elevational view of the apron guiding device; Fig. 8 is a side elevational viewof Fig. 7 Fig. 9 is a sectional plan view taken on the line 99 of Fig 7 and'looking in the direction of the arrows; Fig. 10 is an e'leva-. tional view of a device for raisingv and lowering the tension rolls; Fig. 11 is a sec= tional elevation taken on the line 11l1 of Fig. 10 and looking in the direction of the arrows; Fig. 12 is asectional View taken on the line 1212 of Fig. 11 and looking in the direction of the arrows; Fig. 13 is a front elevational view illustratina the. driving mechanism; and Fig. 14:18 a detailview to be later described. A

Referring to these drawings: A represents the frame of the machine, which is provided with bearings and supports for the various rolls and ironing-chests hereinafter to be described. Fixed in the frame A are a. plurality of hollow ironing chests 1, 2, 3, and 4- i which are substantially crescent shaped in cross section. All of the chests are alike. in structure and are preferably arranged in two vertical rows, the'chests in one row being staggered with relation to the chests in the other row, all as clearly shown in Fig. 2. While I have illustrated four of these ironing chests, it is to be understood that any desired number may be used, as sin or eight,

the additional chests being placed over chests 3 and 4: and arranged in a similar manner.

Adjacent each ironing chest is an apron driving roll as indicated at 5, 6, 7, and 8 and each of these rolls is rotatably mounted in the frames A and positively driven in a manner to be described. On the lower side of chest 1 is a roll 9 which is rotatably mounted in the frame A and driven in a. manner to be described. On the Other side of chest 1 is a similarroll 10 which is movably mounted and arranged to be subjected to pressure by mechanism to befdescribed'. The rolls 9 and 10, hereinafter called pres sure rolls, carry a plurality of narrow tapesv 15 '(see Fig. 6) and these tapes are arranged to contactwith a large part of the peripheral surface of the chest 1.

11 and 12 represent other pressure rolls which carry tapes 16 bearing against chest 2 in manner similar to that already described.

13 and 14 represent endless aprons upon and between which goods to be ironed travel through the machine. These aprons are suitably supported and guided. around the ironing chests and pressure rolls by idler rolls 17 to inclusive and are driven by the rolls 5, 6, T,-'and 8.

All of the rolls described are preferably made hollow as shown with the exception of rolls 26 and 31 which are solid rolls. The latter act as tension rolls for the aprons 13 and 14 respectively.

The connections for operating the apron driving rolls 5, G, 7, and 8 will now be described and particular reference is made to Figs. 1 and 13. Each of these rolls bears at one end thereof a spur gear as shown in Fig. 1 and these four gears intermesh one with another forming a train. One of the train, the gear on roll 7, is driven by a pinion 34 and fixed to the latter is a bevel gear 35 which meshes with a bevel pinion 36. This pinion 36 is slidably keyed to a shaft 37 and fixed to the latter is a. disk 38.

39 is a friction driving wheel bearing upon disk 36 and being movable radially thereon by the lever 40 in an obvious manner. The wheel 39 is slidably mounted on shaft 41 to turn therewith and the latter may be driven in any suitable manner for example by the motor 6 shown in Fig. 1.

The shaft 37 is mounted in a frame 0 re-' movably secured to frame A as shown in Fig. 1. Near the lower end of shaft 37 is a shoulder 42 resting against a bearing 43 which is slidable in a fixed casing (Z. Also slidable in the latter is a part 44 and between parts 44 and bearing is a coiled spring. The lower end of part 44 is rounded and is supported by a roll mounted in an arm 46 pivoted at 46. Thus, with the parts in the relative positions shown in Fig. 13 the shaft 37 and disk 38 are forced upwardly against friction wheel by spring pressure. lVhen, however, the roll 45 is moved to one side, the part 44, bearing 43 and shaft 37 drop allowing disk 38 to engage with a surface on the upper part of frame 0. This surface 7 acts as a brake and quickly stops the rotation of all the driving rolls.

The arm 46 is forked as indicated in Fig. 13 to receive a rod 47 and the latter is ex tended on either side of arm 46 to levers 48 one at the feed and one at the delivery end of the machine. These levers 48 are operable by hand, when desired, and are also operable automatically to prevent injury to the operator, when feeding goods to the machine.

49 represents a board which extends downwardly adjacent the rolls l8 and 33 and is p votally mounted at 50. This board 49 has a bell crank extension which is connect ed by a link 51 to the lever 48. A slot in link 51 permits slight movements of the board 4.) without operation to the lever 48. VVhen, however, board 49 is moved to any great extent, as in the case of an operators hand passing within dangerous proximity to the rolls 18 and 33, the lever 48 is moved and roll is carried to one side. Thus the disk 38 is disconnected from the wneel 39 and is quickly braked by the surface 7" to stop the machine.

The manner of driving the pressure rolls 9 and 11 and the manner of subjecting the tapes 15 and 16 to pressure will now be de scribed and particular reference is made to Fig. 3. The roll 5 has been described as driven by the gear shown in Fig. 1 by suitable connections and upon the opposite end of roll 5 is a sprocket 52 which drives by a chain 53 a sprocket on the pressure roll 11. The latter also has mounted thereon a gear which meshes with a similar gear on the end of roll 9 as clearly shown in Fig. 3. The rolls 10 and 12 are loosely mounted in the ends of hell crank levers 54and which are pivotally connected at 56 and 57 to the frame A. The other extremities of levers 54 and 55 are connected to piston rods 58 and 59 which are movable in cylinders 60 and 61. The latter are pivotally mounted at 62 and 63 and may be actuated by any suitable means to more levers 54 and 55 for example by steam pressure.

Each of the ironing chests 1, r2, 3, and 4 hereinbefore described are heated preferably by live steam and Fig. 4 shows in diagrammatical form the layout of the heating system. Steam enters from the upper end of the machine by a pipe 64 and is distributed by the smaller branch pipes to each of. the chests l, 2, 3, and 4. Each of these chests is also connected near the lower portions with independent drip pipes 65 which each lead to a common manifold 66 and thence to a return pipe 67. Each pipe 65 has formed therein a V-shaped trap 68 and all these traps are arranged at the same level. These traps 68 are arranged to drain all of thechests equally and prevent the possibility of live steam in one chest while the others are filled with water of condensation. Thus, this arrangement insures the heating of each ironing chest to an equal degree.

Each ironing chest is covered with av thin sheet of non-rustable material. such as indicated at 69 in Fi g. 5 in connection with chest 1, which forms a smooth working surface. T his sheet 69 is suitably secured to the chest and at the upper and delivery end thereof is extended beyond the chest forming a spring finger 70. The latter acts to hold the goods being ironed to one apron, such as 13, until they have traveled a suflicient distance to be safely transferred to the other'apron, such pawl 97 is forced from engagement with the ratchet teeth and the roll 26 drops by gravity upon the apron 14. The weight of the roll and the speed with which it falls quickly puts the necessary tension upon the apron. However, in falling the gear train is turning at a very high speed and it is desirable to prevent the ratchet 92 and hand wheel 93 from so doing. This is accomplished by the peculiar shape of the tooth connection 91 and the yieldable engagement between'the members 91 and 92 due to the spring '94: which permits the member 91 to snap past the member 92 in one direction without turn-' limited axial movement between the hand wheel 93 and the ratchet 92.

The ironing operation will now be described with particular reference to Figs. and Goods to be ironed'are laid upon the apron 13 over a'feed board 64, carried over roll 18 and thereafter between aprons 13 and 11 which travel outside the tapes 16 and partially around rolls 12 and 11. The aprons 13 and 1stv separate between the pres sure rolls 9 and 11 and the goods to be ironed are carried by apron 13 against the chest 1. The tapes 15travel with the apron 16 and yieldingly force the latter and the goods against the chest. In passing around chest 1 the goods are ironed on one side while still moist and, as they leave the chest, are transferred from apron 13 to apron 14, the fingers assisting in the transfer as already described. The apron 1% passes around the drive roll 5 in under idler roll 19 and carries the goods, with the unironed face up, against the chest 2. The tapes 16 act in a similar manner to force the goods against the chest with a yielding pressure. As the apron 1 1 and. goods leave chest 2 the goods are transferred to apron 13, the latter.

being carried upwardly and over roll 6 and under roll 20. The apron 13 carries the goods around chest 3 while the apron 14L passes over roll 7 to meet apron 13 as it leaves the chest. Similarly the goods are again transferred to apron 14 to be carried around chest 1 and this operation may be carried on indefinitely, the goods having alternate faces presented to each chest. By

the time the goods leave chest 1 they are practically dry and have been ironed twice on each side. They are then carried by apron 13 over rolls 23 and 24B and allowed to drop on a delivery table Z). The apron 13 returns by rolls tension roll 26 roll 27.

pressure rolls 10 and 9 and roll 17 to the' starting point. The apron 14: returns over rolls 28, 29 and 30, tension roll 31 and rolls 32 and 33 to the feeding table a.

Thus I have provided an improved ironing machine in which the goods are ironed alternately. on opposite sides and in which the goods are forced against the ironing members n a yieldable manner.

It is well known that many modifications may be made in the structure here n de--' scribed without departing from the scope of ironing members, feeding and guiding,

aprons passing around said members, said aprons arranged to feed articles to said members and from one member to another, means to cause a relative movement between the aprons and said members together with a device comprising a plurality of belts arranged yieldingly to independently force said aprons against said members, pressure 7 rollers over which the belts pass, and means comprising, cylinders, pistons therein, and

connecting means between the rollers and pistons. I V

2. An ironing machine comprising "in combination, a plurality of parallel rows of stationary ironing members, an independent apron for each of said rows, means to drive said aprons, together with means for causing the article being ironed to be transferred from the first member of one row to the first member of the second row and thence to the-second member of the first row to the secondmember of the second row and so on through the entire machine, all constructed and arranged so that the article is engaged alternately on opposite sides by said members.

3. An ironing machine, comprising, a plurality of rows of stationary ironing members, means to heat said members, an apron constructed and arranged so that goods of varying thickness may be lroned simultanefl ouslyand goods wlth buttons may be ironed without breaking the buttons. v

4;. An ironing machine, comprising a plurality of ironing members, feeding aprons arranged to convey articles to be ironed to and around each of said members, means todrive saidaprons to cause a relative movement between the articles and said members, yieldable means comprising a plurality of independent belts traveling with said aprons to force the latter and the goods against some of said members,'and means toplace tension on said aprons, said aprons arranged alternately to present opposite sides of the articles to beironed to said members.

as 14:. The aprons 13 and 14 are liable in their course of travel through the machine to run to one side or the other of the rolls and require frequent straightening. Figs. 7 and 8 show a device for automatically straightening the apron whenever it runs to one side. In the machine this device is applied to the rolls 28 and 29 for automatically guiding the aprons 13 and 14L respectively. A description of one of these devices will suffice since both are exactly alike.

The roll 29 (see Fig. 7) is mounted at one end in a swivel bracket it (see Fig. 1) and at the other in a bearing 9 which is slidably mounted in a bracket secured to frame A. The stub shaft for the roll 29 is indicated at 71 and formed on the end thereof is an eccentrically located pin 72. This pin rides in a vertical slot 73 formed in a block 7 4 which is slidable relative to the bearing 9. roll 29 is turning continuously, the block 74 is given a reciprocatory movement of small amplitude. Pivotally connected to the block, as shown in Fig. 9, is an arm 75 which extends vertically upward and has a slot 76 therein. On either side of its pivotal connection arm 75 is formed with integral pawl extensions 77. Below the latter and fixed to the bracket 6 is a plate 78 which has, on each side of its central portion, oppositely disposed ratchet teeth. Pivotally supported by an integral arm g of the bearing 9 is a sleeve 79 and rotatably mounted within the latter is a sleeve 80 and a shaft 81. Loosely mounted on shaft 81 is an idler roll 82 which bears upon one edge of the apron 14. On either side of the roll 82 are segments 83 and 84 which are fixed to sleeve 80 and shaft 81 respectively. Fixed to sleeve 80 and shaft 81 at their other ends are cranks 85 and 86 respectively which each have crank pins riding in the slot 76 in arm 75.

The roll 82, when in engagement with the apron 141- will hold the segment 84: away from the apron and the segment 83 away from the roll 29. In operation, if the apron 14 travels to the right, the roll 82 will drop upon the roll 29 allowing the segment 84 to contact with the apron 1 1 which traveling continuously, turns the segment 84: and thus the crank 85. The latter will turn arm 75 to the left, as viewed in Fig. 7, and allow the left hand pawl 7 to engage the ratchet teeth on plate 78. Thereafter, the block 74: will, due to its reciprocatory movement, slide the bearing r to the right by small increments. As the apron 14 straightens upon the roll 29, the roll 82 will ride back upon the apron and withdraw the pawl 77 from the ratchet teeth. If the apron moves to the left, as seen in Fig. 8, the segment 84 will be engaged to turn crank 86 which operates in a like manner in cooperation with the reciprooatory block 74 to shift bearing 9 to As the the left, as viewed in Fig. 7. Thus the apron may be automatically guided upon the roll.

The means for raising and lowering the tension rolls 26 and 31 will now be de scribed. These rolls are solid and are arranged by their weight to place the aprons 13 and 1 1, respectively under tension. It is necessary at times to diminish this tension and, when the machine is not in use, to en tirely relieve the tension. This is accomplished by raising the rolls 26 and 31 by mechanism disclosed in Figs. 10, 11 and 12. The roll 26 is rotatably mounted at each end and in a bearing 7' and above the roll and mounted in the member j is a rod 99 which has fixed therein a pin extension 99. ll iounted on the pin 99 is a pinion 87 which meshes with a rack m suitably secured to the frame A as shown in Figs. 11 and 12. Also fixed to frame A and in parallel relation with rack m is a bar Z which bears against one side of the bearing 7'. The rack m and bar Z thus form vertical guideways for the roll 26. The mechanism just described is also provided on the other side of the machine so that, when the pinion 87 is turned to move shaft 99, a pinion on the other side of the machine is turned thereby so that both ends of the roll 26 may be lifted equally.

Fixed to the pinion 87 is a, gear 88 which meshes with av pinion 89. The latter is loosely mounted on a pin 96 fixed to the bearing j and has fixed thereto a gear 90 which engages a pinion 91 loose on the pin 99'. The pinion 91 is movable by a ratchet 92 through the saw tooth connection 91 and the ratchet has formed in its hub portion slots 101 (see Fig. 1st) which are engaged by projections 102 formed on the hub of a hand wheel 93. Thus by turning the latter the pinion 91. may be operated to lift roll 26 through the back gear train described. A spring 94 tends to force the members 91 and 92 together and, when these parts are so positioned, it is to' be noted that the projections 102 enter only part way into the slots 101 (see Fig. 14). Pivotally mounted on the pin 96 is an arm which extends upwardly and lies idly against the tips of several ratchet teeth 92. Integral with the arm 95 is a pawl arm 97 and a depending weighted a rm 98. The latter operates to hold the pawl away from the ratchet teeth 92 and when the roll 26 is raised, the pawl 97 must be manually held against the ratchet 92. When. however. the roll has been raised, the pawl 97 will be held frictionally in position by the weight of the roll 26 so that the latter can not drop until the pawl 97 is released. In starting the machine, it is desirable to place the aprons 13 and 14 under tension as quickly as possible and this is accomplished as follows: Assuming that the roll 26 has been lifted to its uppermost position, the
