MACHINE FOR IRONING FOLD-COLLARS.

SPECIFICATION forming part of Letters Patent No. 783,433, dated February 28, 1905.

Application filed April 7, 1904. Serial No. 202,033.

To all whom, it may concern.-

Be it known that 1, LEWIS R. HEIM, of Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Ironing Fold-Collars, of which the following is a specification. v This invention relates to that class of laundry machines or apparatus wherein heated rollers are employed for ironing collars; and the object of the invention is, in part, to provide means for imparting a rubbing or ironing movement to the shoe, in part to improve the operating mechanism, in part to provide means for applying moisture to the fold-of the collar, and in part to provide other details of features which will be hereinafter described. I

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a plan view of the machine. is a sectional elevation, the bed or support being in section substantially at line 00 in Fig. 1 and the operative features or parts in front elevation. Fig. 3 is a sectional elevation of the bed or support, the section being taken substantially at line {fin Fig. 1. Fig. 4 is a sectional plan, the table of the support being omitted,-so as to show the mechanism below it. The plane of the section is indicated by line m in Fig. 3. Fig. 5 is a sectional view of the standard or collar support. Fig. 6 is a sec tional view of the support for the ironer.

Figs. 7 and 8 are detail views of the cam device' to be actuated by a treadle. Fig. 9 is a fragmentary View of means for securing the standard.

1 designates the bed or support on which the operative mechanism is mounted. The top of this support forms the table. Rotatively mounted in bearings on the support is the shaft 2, driven through a pulley 3 thereon. The pulley is normally loose, but may be connected to the shaft by a suitable clutch device 4:. On the shaft is a worm or screw The worm-wheel 6 is on the journal of the Fig. 2

roll 7. and this roll drives the other roll, 7 through gear-wheels 8? and 8, on the journals of the respective rolls, and an intermediate wheel 8 to cause the rolls 7 and 7 to turn in the same direction. A movable upright shaping-roll 7 is driven from the roll 7 by a spur-wheel 8 on said roll 7 which gears with a spur-wheel 8 on the journal of the roll 7. This driving mechanism has not in itself any special novelty and it may be varied without departing from the present invention to any material extent. The rolls 7 a and 7 are fixed in their upright position and have only a rotary movement about their axes. The movable shaping-roll 7 is carried on a swinging bar 9, which has a limited swinging movement about the point 10, Figs. 2 and 4, where it is pivoted to the table of the support. A spring 11, coupled at one end to the bar 9 and at the other end to a screw threaded rod 12, provided with a tensionregulating nut 13, serves to hold the jects upward through an aperture in the table of the support and this aperture is large enough to allow the desired lateral movement of the roll. In order to swing the bar 9, a cam device is employed, which may be operated by a treadle. ()n a stud 14, Fig. 7, projecting from the bearing 16 of the intermediate wheel 8 is rotatively mounted atubular cam 15,hav ing concavities at its ends that fit up to the said bearing 16 at one end and to the bearing 17 of the roll 7 at the other end. Secured in the cam 15 is a projecting arm 18, to which is coupled a strap,chain,wire, or other connector 19,that may extend down to a treadle or lever. (Not shown.) A pull on said connector rocks the cam, and the effect is, as seen in Fig. 8, to move the bar 9 and swingthe roll 7 outward. When the pull is relieved, the spring 11rotates the cam back to its first or normal'position. (Seen in Fig. 7.) It is not, of course, essential that the concave recesses in the ends of the cam shall [it up snugly to the bearings as shown. By a quarter-turn of the cam the bar 9 is moved a distance equal to the depths of both end recesses thereof. In order to impart the proper form to the collar at the fold and to apply the proper pressure at the proper points, the rolls have the shape or contour seen in the drawings-that is to say, the larger rolls 7 and 7 are cylindrical at their larger upper ends, as seen at ain Fig. 2 and taper-downward slightly. The lesser movable shaping-roll 7 has a reduced neck I) at about the level where the fold of the collar passes between the rolls. The contour of the roll 7 may be seen in Fig. 2.

The standard (seen in section in Fig. 5 and in plan in Fig. 1) is mounted on the table of the support 1 by a screw at 21, so as to be movable to some extent about or at said screw, as seen in the detail view, Fig. 9. This standard is so formed as to be narrow at its top or upper edge and is slightly curved at this edge when seen in plan, as in Fig. 1. It has in ita hollow 22 at the base to receive a-perforated gas-pipe 23 for heating it, and it has also a hollow or cavity 24, which receives steam from a branch steam-pipe 26, and as lot in its upper edge, from which the steam escapes to moisten the inner surface of the fold-collar passing over the standard. Steam is supplied to the outer surface of the collar to moisten it through a branch pipe 26, Fig. 1. The steam may come from any generator or source.

Mounted saddl'ewise over-the standard 20 is an ironer 27, which has a to-and-fro or reciprocating movement for ironing and. an upand-down movement for allowing the admission of a collar under it for ironing. The construction and mounting of this device will now be described.

On the end of the shaft 2 is a crank-pin 28, which is coupled by a link 29 to one arm, 30, of a bell-crank leverfulcru med on the under side of the table of the support at 31, the other arm, 30, of said bell-crank lever being rigidly connected to the tubular stem 33, Fig. 6, which carries the ironer 27. This latter has on it a pendent tubular or hollow socket 27, which embraces and is slidable on the stem 33, and a screw or stud 34 engages a slot 35 in the wall of the said socket, thus preventing the ironer from turning on the stem 33, while it is free to move up and down on the latter to a limited extent. Extending up through the stem 33 and secured at its upper" end to the ironer is a rod 36, which is screw-threaded at its lower end and provided with a nut 37. Between this nut and the lower end of the stem 33 is a spring 38, which tends to draw down the ironer yieldingly onto the collar being laundered. When the main shaft 2 is rotated, a reciprocating movement is imparted to the ironer 27 in a curved path corresponding to the curve of the standard, this movement being effected by the crank-pin 28, the link 29, and the interposed bell-crank lever 30 30. The ironer is lifted or elevated' slightly when the cam 15 is rocked. This is effected by means best seen in Fig. 3. A bracket-cam 39, carried by the bar 9, takes under the end of the rod 36 and raises the ironer when said bar swings outward.

The rolls 7, 7 and 7 b are heated by gas supplied through branch pipes 40 and 4O from a supply-pipe 41, and the pipe 23, whichsupplies gas for heating the standard 20, branches also from the pipe 41. The branches 40 and 40 are hinged to the supply-pipe 41 at 42, and the former supplies a jet or jets to heat also the ironer. The hinge permits the branch pipes to be turned back out of the way.

The slot 25 in the upper edge of the standard for the emission of steam to moisten the inner surface of the collar at the fold is in the exterior part of the standard not covered by the ironer, as indicated in Fig. 1. It is desirable that the standard shall not be secured rigidly to the table by its screw 21, but be left a little loose, so that it can adjust itself to the collar and the ironer during the operation of the machine. This is seen in the fragmentary view, Fig. 9.

The link 29 has a construction (clearly shown in Fig. 2) which allows free movement at the joints in two directions.

It may be explained that the tops of the rolls and of the ironer are hollowed for convenience in beating them with gas-jets; also that 4 is a handle for operating the clutch 4 to set the machine in motion or for stopping it. These features are not herein claimed.

There is an upright stationary piece 43 (seen in Fig. 1) set and fixed on the table and bridging the space between the rolls 7 and 7 to prevent the collar being ironed from passing between said rolls.

In Figs. 3 and 4 a screw '44 is seen set in the bar 9, and impinging on the bearing of the roll 7". This screw limits the inward movement of the bar 9 under the influence of the spring 11. This limiting-stop is important, as it regulates the pressure of the roll 7 on the collar.

The operation will be readily understood.

The machine is set in motion by manipulating the handle 4. The rolls, ironer, and standard will be hot from the heat of the gas-jets, and the steam may be turned on to slightly moisten the collar. The operator by drawing down on the chain or connector 19 presses back the roll 7 and raises the ironer. A collar is passed in until its tab will be nipped by the roll 7 and the pull on the connector 19 is then relaxed. The rolls now draw the collar slowly through the bite of the rolls, and the moving ironer 27 irons the collar at and adjacent to the fold. The steam may be regulated in quantity or be cut off by a stop cock or valve 45 (Seen in Fig. 1.) The steam-pipes have been omitted from Fig. 2 in order to avoid confusion. They are clearly shown in other Views.

It will be noted that the ironer moves in a curved path to and fro over the curved track formed by the upper edge of the standard, the movement being about the fulcrum 31 as a center. The standard and ironer are both in front of the feed mechanism and receive the article to be ironed in advance of its engagement with said mechanism.

The purpose in producing a neck 5 on the shaping-roll 7 is to prevent undue pressure on the collar at the fold and to give the fuller and rounder form.
