Application June 17, 1947, Serial No. 755,133

This invention is a hat flanging machine Various machines have been proposed, and some used, for the mechanical ironing of hat flanges; that is, the pressing is done by machines including means to apply an iron, of one kind or another, to the flange-the intent being to eliminate manual iron operation. Machines that are now in use, and the patent art machines are not what can be called simple, mostly necessitate a running support for the hat to be pressed. Machines for this purpose and now in use are very costly, are cumbersome and heavy, and, most seriously, are not of rapid operation in capacity production.

Therefore, it may be stated that one of the cardinal objects of the instant invention is to provide an automatic flanging machine that is relatively simple, considering the problem, and of high production capacity.

A high purpose of the invention is to provide a flanging machine which reduces operator's attention to a minimum so that one operative of average ability may attend to several of these machines while they are running without noticeable fatigue. Fatiguefrom manual ironing of hat flanges is notorious and operatives must have frequent rests or change of work during a day's time at work.

Another and important object of the invention is to provide a flanging machine in which running assemblies are reduced to a minimumthis machine incorporating but a single organization which requires motion during the ironing processt'jthat organization including a rotative ironing head. 7

Also, an object of the invention is to provide a machine powered mechanism for instantly shifting the ironing head toward and from a hat supporting, flanging block, and in-this connection an object is to provide means to be manually actuated so that the ironing head may be shifted away from the block irrespective of the instant position of the head shifting mechanism.

. Provision is given by this invention for the safe holding down of a hat block on its associated conventional portable-type stand by operative parts forming a feature of the ironing head," and a provision is made to greatly facilitate the temporary mounting of one or another of an assortment of hat blocks on one of the and n geasily mechanically accomplished,

,33 Claims. (Cl. 223-14) or "band edge of the'hat flange. This invention provides an ironging head having certain ironing members functioning expressly to carefully work on an annular zone of the flange immediately adjacent to the band edge whilst other coordinate and relatively independently moving iron members are at work on respective zones o'f the hat flange outwardly from the band'zone.

The invention has as a further object the pm vision of means which will permit of the very rapid and reliable placement'of successive stand-'- and-block sets, each carrying a properly applied and secured hat, into given position for the linmediately following, lowering of the ironing head onto the hat and the rapid rotation of the said head in its effective position on the flanges, and

it can here be stated that means are providedwhereby to carefully predetermine the effective weight of the ironing head in operating position on the engaged (and sheathed) hat flange. And means are provided whereby if so desiredwateri vapor can be supplied at the hat flange. v The present machine is for the rapid pressing of hat flanges which areoval in plan and generally curve upward at the rim and means are provided to elfect an oval, orbital motion of "the ironing head in close conformance to the figure of the plan of the flange.

For economical operation and safety means are--included for electrically heating the ironing head by providing-certain of its ironing mem-'- bers with included heating elements of approved type, other elements of the head being heated by radiation from the generating members,anirautotive so wishes.

"The mechanism which functions to lower andraise the ironinghead is preferably of a type in--': eluding a fluid pressure operated piston and the invention embodies a swivel connection whereby the rotative head is suspended and which provides for the ready upward shift of the 118311 381. sembly whilst the suspending piston may be'ini its lower position. Also this connection provides for a lost descending motion of the swivel-- hanger device immediately after the ironing ele--' ments of thehead have come to reston the presented hat flange it will notbe repeatedthat to effectively, rapidly and safely press the inner the hat flange is normally covered by a moist and protecting fabric). This lost motion swivel safely allows for very material vibrations of the ironing head incidental to irregularities of hat flanges and the supporting blocks that may be presented to the effective head.

With respect to the ironing head its structure involves a rotary carrier, which will hereinafter be called the member, and with it is reciprocatively combined a basket having a set of independently pivoted, closely nested, generally flat, parallel respective-zone pressing elements Since the whole head structure will operate ata considerable degree of heat, an object here is to provide an eflicient and long life bearing between the said member and the basket.

The invention resides in certain advancements in this art as set forth in the ensuing disclosure and has, with the above, additional objects and advantages as hereinafter developed, and whose constructions, combinations and details of means will be made manifest in the following description of the herewith illustrative embodiments and their manner of operation; it being understood that modifications, variations and adaptations may be resorted-to within the scope, spirit and principles ofthe invention as claimed in conclusion hereof.

Fig. 9 is an elevational, vertical section of the elevatingjack assembly (omitting certain parts just above the ironing head block). Fig. 10 is a detail view of the hold down device for the driving pulley of the ironing shaft. Fig. 11 is a detail view of a shaft brake locking key. Fig. 12 is a diagram of the electrical circuits. Fig. 13 is a plan of an iron tilting cam. Fig. 14 is a sectional elevation of the head shown in plan in Fig. '7. Fig. 15 is a; vertical section along the axis of the tilting irons of Fig. 14. Fig. 16 is a plan of the elliptic, iron reciprocating cam.

On a suitable bed 2 there is a central, friction pad 3, Fig. 2, on the rear portion of which is fixed a V-plan jig 4 opening forwardly for the ready and quick insertion and solid positioning of a suitable and preferably standard type of flange stand 5, commonly of elliptical and tubular form. Onto the top of the stand is readily attachable (ata remote hat bench not shown) one or another of a variety of flange blocks 6, Fig. Lento the top of;which a hat flange is imposed, and generally moistened. A portion of an applied hat flange F is shown in Fig. 3; being omitted elsewhere for. clarityof disclosure of the mechanism.

These flange blocks are of hat flange shape in plan and are of ring form, and the crown of an applied hat hangs in the block chamber of the stand 5. It is highly desirable that the flange block be securely disposed on the stand 5 to prevent tilting and objectionable vibration of the block on the stand when in ironing position in the machine herein described.

Therefore, to provide for fast assembly of a flange block on a plate or iron flange stand, and to secure long life of the block for repeated use, in hat ironing operations, the stand is provided with front and rear dowel pins 8, in its top face, to readily enter the conical mouth, pin centering, armor sockets} sunk inv the flat bottom of the block 5, Fig. l. The conic mouth 9m,facilitates rapid placement of a flange block onto the pins of a stand (before insertion of the stand in this ironing machine). The sockets 9 prevent wear of the wooden blocks and with the elongate pins 8 fitting well into thebores of the sockets make an effective stabilizing connection of the block onto its stand and make a safely portable assembly to be quickly thrust into the bed jig. The side walls of the jig fit and center the block stand, whose rear'flat-wall 4r rests firmly on the back wall of the jig; which thus centers and supports the stand, aided by the friction pad 3.

Rigidly upstanding from the bed 2 is a substantial frame It which supports the several mechanisms of this machine. There is suitably journaled in this frame a substantial, rotary andpreferably tubular shaft H, a feature beingfthat a vaporous fluid is supplied to this shaft by way of a flexible hose [2, Fig. 9, to a fixed'fitting 1-3 feeding shaft ports 14' just below a shaft boreplug (5; aplug l8 closing the lower end of the shaft, this hanging vertically over the center of the reinovably interposed flange block on the bed. The vapor is discharged from the shaft byway of a small, rigid tube 11, Fig. 14, directly ontothe flange of a hat being pressed by a next described ironing head.

The ironing head.

Figs. 14 and 15 illustrate oneembodimentof an ironing head. The headhere disclosed is distinguished'by the provision of asystem of wholly independent plates or irons each of which is de-. signed to orbitally traverse a generally oval zone of a hat flange while the flange is, solidly. supported ona flange block 6, Fig. 14. The plates are of suitable thickness and flat and vertically dis-. posed side by side in a close gang and vertically oscillate on a common transverse spindle 20. The spindle is supported at its ends in parallel vertical side walls 2! and 22 of a gang basket which slidably embraces a substantial carrier member 23 rigidly fixed on the lower endof the shaft ll; Fig. 7 showing the carrier member andits irons in, plan.

To effect efiicient reciprocation and easy lubrication of the hot iron cage on the member 2.3 upper and lower pairs of block-shape bearings 24 are pivoted on cross bolts 25 in the cage wallsv 2l-22 and beyond opposite sides of the inter-- posed shaft i I to provide for across-shaft reciprocation of the Cage on the member 23, horizontally above the flange block 6. A substantial tension spring 26 connected to the, plug 15 and to the cage tends to constantly pull the cage in one direction against a controlling cam device, mentioned later.

Referring in detail to the pivoted irons as best seen in Figs. 8 and 14, a central iron 28 pivots directly on the spindle 20 and moves freely between the cage walls 2l--22 and under a bridge 29. aflixing said walls at one end. Fig. 14 shows certain irons broken away to uncover the bottom portion of the central iron 28 as being in a position to engage and press a zone of the hat flange immediately at and aroundthe band seam of the flange.

It isa particular'objectof, this invention. to provide an iron of plate form which will"very-= roller 30 constantly pulled by a spring 29s against a step-face cam 31 rotatively mounted on the bridge 29 and fixed to a star wheel 32 which,as the shaft I l rotates the carrier member 23 and its cage, will intermittently engage an intercepting, fixed prong 33 on the frame 10. r g

To secure a very efficient ironing head the spindle 29 is provided with stepped journal sleeves 34 outwardly of the walls 2l22 and on the steps thereof is a right-hand side set of irons or plates 35, 36 and 31 which are slightly rela-- tively spaced for free action on their sleeve 34. On the left side of thecage is a set of irons 38, 39'and-40, on respective steps of their sleeve .34.

The irons of the two said sets all-freely swing.

vertically and their-outermost bottom edgeportions are adapted to firmly drop into effective position on respective, concentric zones of the.

presented hat flange as the entire ironing headis lowered for that purpose, as will be explained.

The tilt of the irons (exceptiron 28) is limited by a stop bar 4|, Fig. 14, on the cage, and-as the ironing edges of the irons 35 to 40,.inc1usive,, engage the hat flange these irons tilt up and their own weight is all the pressure imposed on the flange at the respective zone. The iron 28 is applied in a nicely determined degree, as hereinafter stated. e

- It is found to be not necessary to provide all of the independent irons of the head with individual heating means. As shown, the center iron 28 is provided with an electric heating element 2871. (of conventional form) and irons 35 and 39 have heating elements 36h and 39h respectively, Figs. '7 and 12, and when these latter are energized the flanking irons on each side of the irons 36 and 39 will be efficiently heated by radiation therefrom; also by conduction.

In the iron 28 there is a thermostatic switch 4| connected in the main circuit 42-43 to break the heating circuit to the elements at a predetermined high temperature. Each of the heating elements is connected in parallel to the main circuit 4243, Fig. 12. I

There is shown in Figs. 1 and 4, a form of ironing head assembly in which all of the independent irons 28, 35, 36,31, and 38, 39 and 40, are arranged on the supporting spindle 29 (and its step bearings) between external cage walls 2lc and 220 which are connected by a bridge 290 at one end and a tie 2925 at the other end, Fig. 1. The walls 2lc and 220 have windows with top and bottom, longitudinal channel tracks 45 in which pairs of bearing rollers 46, having trunnions'4'l in the driving member 23', operate due to longitudinal reciprocation of the cage which carries the ironing head (the iron assembly).

The iron reciprocator channel cam 50 which fits in the cap groove 48g to keep it from vertical motion as to the cam... Fig. 16. A cam roller 49 is pressedinward by a.

tension spring 26; the outer wall of the channel cam preventing undue out thrust of thecage, as

might occur; and the main cam roller 49' normally running on the rim.of the cam .50. The cam 50' is rigidly-secured to a cross-brace of the frame l0, concentrically of the shaft ll and therefore as the cage isrotated by the shaft the oval .contour of the cam causes the cage tov concurrently reciprocate with the resultant generally ovate orbital sweep of the ironing assemblyv while the irons are in engagement with a hat flange reposing on the flange block 6 then interposed below the ironing head, Fig. 1.

Iron raising and lowering means Before a hat block can be safely put in ironing position under the ironing head this should be elevated a suitable degree. Moreover, it is desirable that when the irons are'inlowered,e1fective position the center iron 28 will have a pre-.

the shaft I I a pulley 52 driven at a suitable speed by a gear ratio motor unit 53. The lower hub of the pulley has a flat flange 54 which is engaged and held against axial shift by yoke arms 55 of a bracket 56 extending up from a ehair'5l. On the chair is pivoted a manual lever 59 whose outer end carries a poise 60 of suitable and variableweight (as by buck shot load) and whose inner end includes a yoke 6| engaging an outer, free ring 62 of a ball bearing mounted on the shaft against end play. By this lever the shaft assembly can be instantly thrust upward to lift the irons from the hat; while the shaftis idle or is rotating. 1

The shaft brake Means are provided for the purpose of arrest-- ing the rotation of the shaft as it is elevated to upper position clearing the ironing head from the work.

Above the shaft vapor joint. I3, Fig. 9, the frame! is provided with-a journ-al.65 on the lower end of which is clamped a collar 66 in which float vertical bolts 61' carryinga brake disc 68 faced with a friction pad 69.

Fixed on the shaft H is a, ball bearing race 10 having an outer ring H on which is fixed a discal brake shoe 12, whereby, as the shaft is elevated its rotation is quicklystopped by engagement, with the fixed pad '69. The brake can be decommissioned, made inoperative, at will by pulling out a latch 13 from a socket 14 in the shaft. The latch can be locked open'by rotation thereof in its sleeve l5to bring a holding pin .16 across the outer end of the sleeve;"thishavifng a longitudinal spline slot- 15s for the pin.

The shaft power flack p A distinctive feature of this invention resides in a power mechanism, preferably of fluid pressure type, for lowering and raising the shaft and its attachments at will of the operative.

' Extending up from the journal '65 there is a fixed sleeve 18 having a top bushing 19 in which is fixed'the lower end oftafpneupiatic motor 7'? cylinder 8|! having a piston. rod 8|. extending down through the bushing. 19:.

' I-n mechanism provision is made for free rotation of the shaft as. to the elevating rod 8| and also for a freev ascent or descent as to the said rod. Hence a swivel is provided including a thimble 82. fixed on the upper end of the shaft, the bore. of which provides for the relative descent of the intruded end of the rod 8|. On the rod end is' mounted .a ball bearing 83in which the'rod is-axially slidable, from the upper position, Fig; 9, to a lower position in the shaft.

- The bearing '83 includes an outer ring 837' which is fixed in the thimble 82 and by which the shaft is raised or lowered by the non-rotative rod 8!, while the shaft is idle or is rotating.

From the above it will be seen that the piston rod lowers the ironing head onto the surface of the subjacent hat flange and after the head is arrestedon the flange the rod can move down. its full piston stroke and leave the full, eifective load of the several irons for pressure on the hatflange- The motor control It is desirable that the motor 53 will be automatically stopped as the driven shaft H is elevated, and automatically started again as the shaft moves down for another pressing operation in the machine, and provision is made for such functions.

Fixed on the frame cross piece is a post 90 on which is sl'idable a spool-shaped cylinder 9! which embraces the near side of the ring 62 and therefore is reciprocated by and with it (and the shaft). The. upper end of. the cylinder 9| has a rim 92 which, as the cylinder rises, engages and throws off a yieldable switch 93 fixed on the frame and thereby breaks the motor circuit 94, Fig. 12. When the shaft H is next lowered the actuating. rim. recedes and allows the automatic switch 93. to again close the motor circuit.

While the motor is idle a fresh hat, on a flange block, is thrust onto the bed 2 and the jack lever 85 is struck down to effect the lowering of the iron carrying shaft H. After a little practice on runningthemachine-the-operative may desire to. speed up production and therefore a by-pass circuit switch 95, Fig. 12, is wired around the automatic switch 93, for use at will for securing continuous operation of the motor and the shaft I'll. The shaft can be 'reciprocated readily at will. during continuous rotation by its motor.

The heater circuit Thecircuit 42-43 includes a pair of y-i'eldable contact brushes 42b and 43b" mounted and insulated in the block 2% and in constant contact with insulated brush rings 421- and 431', Fig. 12,.

fixed to the stationary cam 50. From the rings extend insulated wires 42-pand 43p connecting to'bus wires P for power from a remote master switch 56 which serves the motor circuit. A local, service switch 91 is provided in the motor circuit for convenient use;

It will be seen that collectively the several irons will effectively cover the entire hat flange surface that is to be pressed.

Figs. 3 and -6 illustrate small. flyirons 38a? having pivots 38p suitably mounted. for instance in an iron 38, toeach sweep in respective, close zones of the flange; as may be desired in some cases-instead of having the foot of the iron itself (10- the pressing.

' The fitting 13 is. swivelled against axial shift on the-shaft l I by key screw [3k interlocking in a respective.- peripheral groove l lg in the shaft- The grooved block 49 has anout-throw con.- trol roller 49" hocking into the channel of the flxed cam 5U, Fig. 14.
