HAT-SIZING MACHINE.

Specification of Letters Patent.

Application filed September 20, 1911. Serial No. 650,449.

To all whom it may concern Be it known .that I, ARNoL TURNER, a

subject of the King of England, and'resident of Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hat-Sizing Machines, of which the following is a specification.

This invention relates to hat forming machinery and refers to that class of machines employed for sizing, shrinking and felting has thus been accomplished by first dippingfour or'five hats in very hot water, then rolling them into a bundle and covering the bundle with burlap, and while in this 'condition they have been rolled backward and forward upon a bench or table for the purpose of working the fur together and mak ing a thicker butshorter bodyi It has therefore been my object to 'produce a practical machine for doing the above work of operating upon newly formed hat bodies preparatory to being further felted, shrunk and sized in a different form of ma chine; to design a machine which could be operated by power and attended by a single operator, and whereby a number of hat bodies may be operated upon simultaneously; to provide adjustin'gmeans whereby hat bod es of different sizes, or bundles of chat bodies comprising a larger or smaller number may be properly treated as occasion may require, and finally to provide a machine for the above purpose whereby the work referred to may be speedily and effectively accomplished and very much cheaper than the hand work heretofore employed.

With these and other objects in view the invention consists in the construction and novel combinat on and'arrangement of parts hereinafter fully described, illustrated in the 'accompanving drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form,

prop0rtion, size and minor details of con- 1 struction within the scope of the claims may be resorted to without departure from the spirit of sacrificing any of the advantages of the invention.

Similar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification, and upon which Figure 1 shows a plan View of my improved apron settling machine complete; Fig. 2 is a sideview of the same; Fig. 3 is an end view as seen from the right of Figs. 1 and 2;'.and Fig. 4 is a central vertical longitudinal section taken on line 4-4 of Fig. 1.

In the designing of this machine I have endeavored to provide a construction which would produce an operative movement upon the hat bodies as near like the hand work heretofore employed as is possible, and which consisted principally of a'backward and forward rolling motion,of the bundle of bat bodies when folded and rolled within a cloth and form ng an elongated rollshaped bundle. My im roved machine therefore includes a movable endless apron having both i a forward and backward move-' ment' for rolling thebundles-of hats back-- ward and forward upon a bed, and whereby the said hat bodies are gradually passed through and out of the machine. The hats are then again dipped in hotwater, refolded and rolled in the cloth, preparatory to being again passed through the machine in a sim larmanner.

Referring in detail to the characters of reference marked upon the drawings. 5 represents the frame of the machine which as will be noted consists of two side uprights, 5 and several intermediate connected crosspieces for tving together and supporting the said side uprightsJ 6 represents the main d iving'shaft upon which is moun ed belt pulleys 7 .for o erating the same. This driving shaft is suitably journaled in bearings formed in the said uprights, and upon this shaft is'mounted a gear 8. a beveled gear 9, an eccentric 10, and a clutch sleeve 11. A drum 12 is loosely mounted. upon the said shaft and serves to sup ort and guide one endof'an endless flexible apron 13, which is preferably formed of rubber and provided with a series of transverse corrugations upon its face better to engage and manipulate a bundle Patented Nov. 24,1914.

of hat bodies. The upper andforward end of the endless apron is in a like manner passed over and supported upon a second drum 14- which is fixed to adriving shaftdt'r' 5 also journaled in bearings of the saidupr rights and operated through worm gear eccentric and clutch mechanism again to be referred to, from the main shaft 6 before mentioned. This drumil lwtherefore serves;

as the driver, while the drum 12 is but an idler, the-apron beingicarried over the-lat ter by the action of theformer, and'similar to that of an ordinary belt; connecting a driven" and" a driving pulley. A series of transverserolls-16, see Fig: 4,- are' journaled against the inside of the uprights and be v tween theibeifore mentioned rolls in awayto support the lower portion of th'eapgron when acting upon aibundie-ofhats. This insures: a uniformpressure upon thehats while being rolled backward and forwarda-nd up the-incline floor; or bed-17- which is arranged between the: uprights and parallel to the underv face OrftllB saidiflexibleapron so as to form a uniform space between the two throughout the operative,movementof the saidiaprona.

The bed referred to is-composed- Eof a series of boards that extend across the; underside of the machine and are supported upon-long.= curvedmeta'l rails:l8r in .a.way to formwone integral part, thatv is, supported atthe corners of the machine and-adapted to be raised andilowered for a purposedaten to bedescribed. The end: portions 19 0f the rails for=-this bed are connected to and supported upom the adj ustahle top cross-pieces 20 locatedat' the" opposite ends of the machine andguidedmpom vertical guides 21 carried by brackets '22 secured to the side uprights. A second cross-piece 23 is also mounted *uponthese guides, and the adjusting screws 24 and a spring25 serve toyieldably support the upper'cross-piece uponthe lower one, said springs being seated betweenthe upper cross-piece, anda lower, collaruponi the screw, while the screw freely passes through the said topcross piece and threadably engages the lower cross-piece.

T'he'b ed, nuts and top cross-pieces are thus loosely supported on the-threaded rodseand guide and are further yieldablyasupported upon the lower cross-piece 23zth rough the medium ofa yieldahle spring 25 mounted upon the before mentioned'adjusting screws 24. Thisserves t0 permitb'oth of the-said cross-pieces20 and'23 mountedupon the rod to be raiseda-ndlowered as occasion may re quire in the vertical adjustmentof the bed with" relation to the apron 13: The two pairs of these cross-pieces at each endof'the; machineare connectedand supported b'y-theuprights: 5 through the medium of the screws 24 and guides-21' asbefore described! The: lower cross pieoes- 23 are; directly sup ported upon the four cams 26'located immediately beneath the ends of the said crosspieces at the several corners of the machine, the said cams being mounted upon crossshafts 27 and 28 journaled in bearings of the uprights. The latter shaft 28 is provided with a hand wheel 29 whereby it andthe four cams may be simultaneously adjusted through the medium of suitable connecting rods 30 extending along the opposite sides of the machine and thusaconnecting the-pairs of side cams andJthe shafts in a way to insure the simultaneous adjustment of all four cams, and thus the raising or lowering. of all: four corners ofith'e; b'ed beforementioned; 30 'Ih-is-adjustment is to accommodate. bundles of difi'erent'thichnesses by. bringing the bed toward or from the-underface of the flexible apron, and whichrolls thebundles of hat bodies 31 backward andi-fo-rward; and-35 finally out' from'the rear end of the machine.-

The means employedzfor obtaining this forward": and backwardmovement of the apron is'best illustrated in Figs. 1. and'290 wherein it will bemotedthat there are two: movements imparted to the feed drum, one through the bevel gear connections 9 to 32-; and I the: other throughthe-eccentric 10 which; imparts a. reciprocating movementto the worin33 splined to the intermediate shaft 3 ijournaled' in'bearings-35' and further rotatedf throughthe medium of the before mentioned beveledgear connections. Thisv reciprocatory rotaryworm mesheswith and drives a=wor1n gear 36mounted'iupon the drum shaft 15' in the manner; and-for the purpose before described: The clutch .sleeve 11 which is splinedto the main shafti 6 serves to engage withthe clutch face on the side ofthe eccentric sothatth'e apron operr ating mechanism connected 1 with the eccentric may: he started-Mr stoppedat will, the said clutch being operated by. lever 37 pivotall'y'connec-ted toa bracket 38 securedto one of the-sideuprig'h'ts 5 The beveledgear-9 is splined to the main-shaft 6 and thus always turns with-it. The eccentric is bored to recei ve the hub of said gear 9' and' is free to run with it 'or'not according to the position of'clutch- 11: This-permits of either a continuous rotary or-areciprocatory motion of the apron, the former being desired at th'estart, as being more gentle.

Theconveyer or transporting mechanism 39 is supported b'y two forward brackets 40 and two rearward'brackets 41, all of which are properly secured to the top of the side uprights; Cross shafts 42, 43' and 44 are journaled in theseuprig-hts while the shaft 45" isournaled in an" adj ustable bearing 52" carried bythe bracket 40 a-nd' aIIsaid shafts are provided with sprockets to engage the openlinksofthe chain 46 ofthe conveyer and to which the cross strips 4E7" are connected. A further sprocket 48 is attached to one end of the cross shaft and connected by the sprocket chain 49 with a lower sprocket 50 mounted upon a short shaft journaled in a stud 51 and bearing a gear 53 that meshes with and is driven by the before mentioned gear 8 upon the main shaft 6. This conveyer, like the apron, is an endless form of device, the intermediate part of the top side being supported upon the sprockets carried on the intermediate shaft 44, while the returning underside of the conveyer is similarly supported upon sprockets carried on the shaft 43. The front shaft 45 arranged across the front of the machine is adapted to be shifted slightly backward or forward by means of the adjusting device 52, whereby the wear and slack of the conveyer can be taken up from time to time as occasion may require.

As before stated the apron 13 is alternately given a forward and backward movement when the clutch is in engagement, and in addition to this I have provided means to insure a slightly greater forward movement than backward movement, or, in other words, the bundles of hats are alternately given a full rotation in a forward direction, and then a reverse roll of about half that amount. This obviously results in a continual forward and backward roll of the bundle of hats and a final delivery of the same from beneath the apron at the rear, where the operator is in attendance to receive and unroll the hat bodies. The four or five hat bodies are then separately crozed, rolled and wrapped into a bundle again as before and laid upon the conveyer, which carries it forward and drops it into the front end of the machine for a furl her and similar operation, said roll being kept in proper position and guided to the apron by means of the shield 5-3 supported on brackets 54 secured to the before mentioned uprights 5 The forward movement of the apron is the sum of the motion imparted to the worm gear by the rotary motion of the worm, through the bevel gears, plus the forward impulse the whole worm gives to the worm gear by virtue of the eccentric. The backward movement of the apron is the excess of the backward impulse the whole worm gives to the worm gear bv virtue of the eccentric, over the motion in the opposite direction imparted to the worm gear by the rotary motion of the worm through the bevel gears, since this latter movement is always in the same direction and amounts to less than the eccentric motion.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a machine of the class described, the combination of a bed upon which bundles of hat bodies may be placed, an endless apron over the bed, means for imparting thereto an alternate forward and backward movement in a way to insure a forward and backward roll to a bundle of hats when placed between the said apron and bed, upper and lower bed-supporting bars at opposite ends of the machine, means for adjusting the dis tance between said bars, and a series of connected cams for simultaneously raising and lowering said lever bar to adjust the bed toward and from the apron.

2. In a machine of the class described, the combination with suitable drums, of an apron mounted thereon, means for imparting thereto a backward and forward motion, a bed arranged below the apron, upper and lower bed-supporting bars at opposite ends of the machine, means for adjusting the distance between said bars and yieldingly support the upper bar, and means for adjusting the lower bars to raise or lower the bed toward or from the apron.

3. In a machine of the class described, the combination with suitable drums, of an apron mounted thereon, means for impartin g thereto a backward and forward motion, a bed arranged below the apron, cross-pieces upon which the bed is mounted, a lower pair of cross-pieces for supporting the first mentioned cross-pieces, springs between the said first and second mentioned cross-pieces. and means for simultaneously adjusting both of said lower cross-pieces and the bed with relation to the apron.

4. In a machine of the class described, the combination with suitable drums, of an apron mounted thereon, means for imparting thereto a backward and forward motion, a bed arranged below the apron, and comprising a series of transverse slats and longitudinal supporting rods, parallel transversebars at opposite ends of the machine adjustable toward and from each other, supporting the ends of said rods, series of cams for raising and lowering said transverse bars, and means for simultaneously operating said cams to effect said adjustment.
