Specification of Letters Patent.

Patented Feb. '12, 1918.

Application filed September 14, 1915. Serial No. 50,596.

To'all whom. it may) concern:

limited to the precise arrangement and or- Be it known that I, ISAAC F. WILLEY, a ganization of these instrumentalities as citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Ironing-Machine, of which ing is aspecification. I My invention consists of a novel ironing machine which is especially adapted forthe ironing of collars. In the machines ordinarily employed for this purpose, it is customary to feed the collars to the ironing rolls in the direction of their length and owing to-the distance between the axes of the rolls and the manner in which the collars are pulled by the operator as they are fed into the machine the original length of a collar is materially increased and the ends and buttonholes are lengthened and distorted in such a manner that the ironed collar herein shown and described.

Figure 1 represents a top plan view of a N collar ironing machine embodying my inthe followdoes not set properly on the shirtof the the collars are fed into the machine in such a manner that they are presented laterally to the ironing rolls with,their entire sur- I face uncovered. The collars are fed laterally or in parallelism with the axes of the ironing cylinder and roll and the direction of movement of the collar is in a continuous forward direction.

My invention further consists of a novell manner of yieldingly mounting the rolls, which cooperate with the main ironing drum so that a uniform tension is placed on such rolls.

It further consists of a novel construction and arrangement of an ironing roll and its adjuncts whereby the. amount, of effective surface of the ironing roll is largely increased during the ironing operation.

Other novel featuresof construction and advantage will more clearly hereinafter apvention. Fig. 2 represents a side elevation thereof having certain portions broken away for the sake of clearness of illustration.

Fig. 3 represents a sectional elevation of the machine, the section being taken on line 33 of Fig. 2.

Fig. 4 represents a front elevation of an alining roll for the feed apron.

Fig. 5 represents a sectional elevation of a portion of the machine showing more clearly certain details of construction, the section being taken on line 55'Fig. 1.

Fi 6 represents a sectional elevation showing more clearly details of construction of the feed apron and certain of its adjuncts. I

Fig. 7 represents a sectional elevation of a portion of the machine, the section being taken on line 77 Fig. 2.

Similar numerals of reference indicate corresponding parts in the figures. Referring to the drawings: 1 designates the housing or an ironing machine, embodying tion, and adapted to be actuate by any desired type ofdriving mechanism. For convenience of illustration, I have shown a motor 2, such as for example an electric or other motor, carried by the housing and having its shaft provided, with a pinion 3, which meshes with a gear 4, mounted on a shaft 5, journaled in the machine framework. The shaft 5 has mounted thereon a pear in the detailed description of my invention.

For the purpose of illustrating my invention, I have shown the accompanying drawings one form thereof which is atpresent preferred" by me, since the same will give in practice satisfactory and reliable results, although it is to be'unde-rstood that .the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not wheel 11, carried by the first ironing roll 12,

which latter is mounted in journal boxes 13 adjustably carried by the housing. The! I ironing roll 12 is in frictional engagement with a feed apron 14, which passes around av front roll 15, the ends of which have loosely mounted thereon the sleeves 16, Fig. 1, the inner ends of which are provided with the inwardly tapered or cone-shaped spools framework of my mvenwhich are in threaded engagement with said journal boxes and rotatably carried by the housing in such a manner as to prevent their longitudinal movements 20 designates cables wound around the sleeves 16 and connected therewith, and

their opposite ends are connected with a support 21, in which is rotatably mounted a roll 22. The support 21 is provided with a stem 23, which is freely rotatable in a bearing 24, which may be vertically adjusted by means of a screw 25. A set-screw 26 maintains the parts in their adjusted positions.

27 designates a belt tightening roll which i is'journaled in brackets carried by the hous- ;ing. The feed apron 14 also passes over a blade'28 adjustably carried by the housing of the machine. r

29 designates a roll, which is located out 0f axial alinement withthe first or upper ironing roll12, and said roll 29 is mounted in journal boxes 30, havingdepending rods 31 guided in apertures in the housing, Figs. 7 and 8; The rods 31 are provided with apertures 32 into which extends rods 33,

which carry at their lower ends rollers 34. Interposed between shoulders on the rods 33 and the lower ends of the rods 31 are springs '35 which maintain said rollers in 35 engagement with cams 36, which are mounted on a cam shaft 37 and may be manually I adjusted by means of the handle'38 to vary the distance between the lower roll 29 and.

the upper ironing roll- 12. \These rolls 12 40 and 29 are intergeared by means of a gear 39 on the shaft of the roll 12 anda' gear 40 on the shaft of theroll 29. The forward portion of the housing is provided with a table 41 which serves as a support for the collars which are to be placedby the operator on the feed a'pron 14.

' The shaft 8 also has mounted thereon a gear 42, which meshes with a gear 43 carried by the main ironing drum or cylinder 44, which is mounted on a: shaft 45, journaled in the bearing boxes. 46. The latter are carried by posts 47 which carry at their lower ends the rollers 48, Figs. 2 and 3, seated on cams 49, on a shaft 50. The shaft 50 has fixed thereto a worm wheel 51, which meshes with a worm 52 carried bya shaft 53 journaled in the housing and provided with a lever 54 which is adapted to be manually operated in order to efi'ect the raising or lowering of the main ironing drum '44.

The posts 47 are guided I in the machine framework.

Coiiperating with the ironing cylinder or drum 44 are a plurality of sets of ironing rolls, any desired number of which may be employed, and for convenience of illustrationT have shown three sets 55, 56, and 57, respectively, and since each set is constructfed and operated in a similar manner, I have deemed it unnecessary to describe in detail but one of such sets. See Fig. 5.

58 designates sleeves carried by the housing in any desired manner and provided ,7

with apertured partitions 59 through which extend the rods 60. The outer ends of such rods are provided with nuts 61 in threaded engagement therewith and contacting with washers 62, between which and the partitions 59 are interposed the springs 63, and since the washers 62 'are adapted to move into the lower chambers of the sleeves -58,

a tension'is placed on the rods 60, which tends to move them inwardly with respect to the sleeves. Thev rods 60 are in threaded or other engagement with the stems or posts 64, which are guided in the upper portions of "the sleeves 58 and each post 64 has journaled therein the ends of a central ironing roll 65. The posts 64 are recessed at their upper ends at 66 and 67 to. receive the springs 68 and 69 respectively. 70 designates journal brackets pivotally connected at 71 with the upper portions of the posts 64.

72 designates an outer ironing roll journaled in the brackets 70 which are recessed as at 7 3 in order to receive the springs 68 j which abut against plates 74 located in the recesses 73 and carried by rods 75 in threaded engagement with the bearing, whereby the tension of said; springs 68 maybe varied,

as desired.

76 designates bolts passing freely through apertures 7 7 in the bearing brackets 70 and in threaded engagementwith fixed portions of the posts 64, and the inner ends of such bolts are, provided with lock nuts 78. 79 designates a bearing bracket located on the side of each post 64 opposite to the bearing bracket 70 and pivotally connected at 80 with the upper end or head of the post 64. The bearing brackets 79 have journaled therein an outer ironing roll 81 and are recessed as at 82 to receive one end of the springs 69, which abut against the plates 83 located within such recesses and carried by rods 84 in threaded engagement with the bearing brackets 7 9, whereby the tension of the springs-69 may be varied, as desired.

85 designates bolts assing freely through the bearing brackets 9 and in threaded engagement with the upper ends of the posts 64 and provided with lock nuts 86.

In order to prevent the curling of the collars as they are fed to the first roll 72, 1 provide a gravity roll 87, Figs. 1 and 2, the ends of which are free to move vertically in the slotted brackets 88 carried by thehousing of the machine. 89 designates a recelving table carried by the housing in any desired manner and having one edge terminating in close proximity to the cylinder 44 and its opposite end is normally closed by a pivoted door 90.

91 designates steam conduits by means of I the drum 44. The rolls 72, 65 and 81 are,

in practice, preferably covered with pad ding and fabric. The stems 95 of the ]011I- nal boxes 13, which carry the ironing roll 12, are slidably mounted in the housing at yan angle to the rods or stems 31. of the journal boxes 30 and preferably at substantially right angles to each other, as shown.

The amountof axial displacement of the f shafts of the rolls 12 and 29 may be varied by actuatingzthe adjusting screws 96 and the set screws 9 4 The operation of my novel ironing machine will now be readily apparent to those skilled in this art and'is as follows Assuming that the variousparts of the machine are in their properly adjusted positions, the motor 2 is started. This causes the gear 3 to revolve and thereby the gears 4, 6 and 7, which efiect the revolution of the sprocket wheel 9 and thereby actuates the sprocket chain 10, which latter imparts rotation to the ironing roll 12. Since the ironin roll 12 is intergeared with the roll 29 an is in frictional engagement with the belt 14, which passes between said ironing rolland the roll 29, a forward feeding move-' 40 ment is imparted to the feed apron 14. The gear 42 which is mounted on the same shaft 8 on which the sprocket wheel 9 is mounted, meshes with the gear 43 and thereb revolves the drum 44. The collars, after eing 45 washed, are treated with starchin any desired manner and are in condition to be ironed.

The operator arranges the collars to 'be ironed transversely with their bottom or inner face uppermost'on the apron 14. The

collars are fed by the feed apron beneath the first ironing roll 12 in parallelism with its axis and since this roll is out of axial -aline-. ment with the roll '29, substantially the entire under surface ofthe collar is brought into engagement with the ironing surface of the roll 12 and the entire inner surface of the collar is ironed, since it engages with a sufiicient portion of the. periphery of the ironing .roll 12.to effect this result. If the roll 29 and the ironing roll 12 were in-axial alinement, substantially only a line contact would be'made with the collars to be ironed. After the collar passes beyond the ironing 65. roll 12, it travels beneath the gravity roll 87 and-is delivered to the ironing cylinder 44 in parallelism with the axis thereof, and then gasses first beneath the ironing roll 72, then eneath the ironing roll 65, and then. beneath the ironing roll 81 of the first set of rolls 55 in parallelism to their axes. The

collar then passes beneath the subsequent sets of rolls in parallelism to their axes and is stripped from the drum 44 by the juxtaposed edge of the receiving table 89 and is discharged on to said table. The collars are .then passed through a seam dampening machine and then through amachine which turns the collar down and dries the edge. The collars are then ready to be sorted and wrapped up for delivery to the owners.

1 provide means to maintain the feed apron 14 in alined position. If the apron 14 rides up on a spool 17 at one side of the machine, the adjacent cable 20 is wound up on the sleeve 16, thereby moving the journaled support 21 with which-it is connected, rear wardly, and thus moving the roller 22 on its fulcrum. This causes the feed apron to be returned to its proper position, and as soon as the feed apron disengages' from a cone 17, the tension roll 22 assumes its normal position, seen in Fig. 1.

Special attention is directed to some of the novel features of my invention.

The journal of the first ironing roll 12 is I adjustable at right angles to the direction tire surface of the collar is simultaneously ironed.

Each set of ironing rolls which-cooperate with the cylinder 44 is yieldingly mounted, it being seen that any desired tenslon may be placed on the post 64 which carries the outer ironing rolls .72, 65 and 81 of a set.

The ironing rolls 72 and 81 are each provided with an adjustable tension dev ce whereby any desired tension may be mamtained on said rolls with respect to the cylinder 44. A tension of anydesired degree is also maintained on the ironing rolls 6 5. By such construction, a uniform tens1on is maintained on all the ironing rolls whlchcooperate with the main cylinder or ironing drum, so that during the ironing opere atlon, a uniform pressure. is placed on the collars and the rolls-are automatically adjusted so that a two ply collar and a collar of a greater number of plies are lroned with an equal degree of success without necessitating any adjustment of the parts.

The collar is fed in a flat condition later-' ally or in parallelism with the axes of the ironing drum and wholly exposed and uncovered: llhe direction of the feeding movement is continuously forward and not reciprocating and both surfaces of the collars are ironed in a sin le passage through the machine, thereby ena ling one to obtain a greater economy in both time and labofand a greatlyimproved result. a .i

In the machines of this general character as hereto-fore constructed, the natural spring inherent to'a collar hasbeen destroyed, since if sufiicient pressure was placed on the small rolls to produce the proper actionon the portion of the collar of uniform thickness, too

quent ironing is necessary great a pressurewas placed on the collars at the seams where the collar is of increased thickness and the surface of the collar was not uniformly polished. In prior machines due to the facts that the axes of the small rolls were at too great a distance apart and the variation in the thickness of padding on the rolls, it was impossible to feed the collars through the machine in parallelism with theaxis of the'ironing rolls. In accordance with my present invention, the axes of .the small rolls are brought close enough together to cause theirtperipheral portions to engage the collars when fed transversely and cause them to travel through the machine;

In so far as I am aware, I am the first in theart to feed a collar transversely instead of longitudinally in this mannerfwitho-ut clamping it to the feed apron and covering so that a subsefor such covered portions after the collar is removed from the machine, and it is to be understood that up portions of the collar,

' my claims to such features are to be inter preted with corresponding scope. I

If the axes of the rolls of each set are not sufliciently close to each other, a collar will" not feed up the high side of the drum and as the collar passed beneath the rolls of the last set of rolls, itwould slide downwardly "on the drum and stick to the collar in ad- Vance ofit, so that the collars would notbe properly ironed It will be evident that v in the broad and -gener1c scope of my invention, the collars pass through the machine with their longitudinal axes s\1bstantially in parallelism with the ironing rolls, and means are provided to effect thecyc'lical operation of the ironing mechanism and the parts .cotSpera-ting' therewith.

It,will now be apparent that I have devised a novel and useful ironing "machine,

which embodies the features of advantage enumerated as desirable in the statement'of the invention and the above description, and awhile I have, in the present instance, shown and described a preferred embodiment theresmaller rolls and is nasaaso of which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
