To a/ ZZ who@ itv may concern.: l i Be it known thatLELMER S. ALvoRD, a citiin the county of Fairfield and State of Connecticut, have invented certainnew and useful Improvements in`Hat-Paring'll/Iachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and us the same.

My invention relates to certain new and usefulimprovementsin hat-paring machines, which are used to pare oit the surplus petticoat7 on ythe edge of` the hat-brimafter the curling operation has been performed. TheA object of my invention is to provide a machine not likelytoget out of order and I l which shall be capable of p'erformig` the paring operation quickly and eiectively; and

with these ends infview my invention consists in certain de tailsof construction and combination'of parts, such as will be hereinafterfully described and then specifically be designated by the claims. m

f In the accompanying drawings, which form a part of this application, Figure l is a side elevation of my machine; Fig. 2, a plan View;

Similar characters of reference denote like parts, in the several`gu'res otthe drawings.

Heretofore great Adilicultyhas been experienced in producinga machine in .which the hat-brim is properly delivered to the cutter. There are a great many things to take into consideration in the operation of paring a hatbrim automatically-namely,fthe hat must` be revolved so as to describe an oval, so that hat.

up toA acertain stationary point; the cutter amount of petticoat "from thev edge-.of the ovoidal brim; means must be provided for tilting the sides and ends of the brim respectively downwardly and upwardly 4when these f portions of the `brim come in contact with the 6cV cutter, because the droop'at the ends of the brim brings those portions in a lower. plane than the sides, and all parts of the hat-brim Y f must-be automatically brought to the same horizontal plane in order that the paring may 65 be properly effected; the hat-block which supports the hat must be capable of being swung by hand so as to bring the hat in `proper position relative to the cutter before the machine is started, this being necessary, since all hats 7.o l

There are two well-defined sets otinechan- 8o isms which I employ-namely, instrumentalities for giving to the hat itself the proper movei ments, so that it may always be presented acv curately tothe cutter, and instrumeutalities.

for presenting the cutter accurately to the 875ir vbrim,so that said cutter may act in conjunction with a suitable foot to properly pare the The means which I employ for'impart-` ing motion to these mechanisms from any 4ksuitable power-pulley are veryordinary and goiv l .hardly require detail descriptions, land I will merely touch upon them brielliy,sincethey-.1 will be readily understood-at aglance'and are well within the range ofv ordinary mechanical skill. I will first describethe'cutter andthe l9,5 foot and the means which Iemploy to give the proper movements tothe cutter.

l is the frame of the machine,and 2 the-bed.

3 is a block capable of sliding freely in'k ways 4 on the'bed and carrying on its upper roo `face avfriction-roller 5. v

6 is a cam carried bya shaft 7, which latthe ovoidal'hat-,briin may constantly be kept i In order to provide a h'at- 7'5 ter is journaled vertically within the bed and the frame of the machine.

y S is a screw driven through an ear 9, projecting from the rear of the bed 2, the inner end of this screw carrying a block 10, and 11 is a coil-spring whose extremities bear respectively against the blocks 3 10, so that it will be clear that the roller 5 is normally kept pressed against the edge of the cam 6.

12 is a block adapted to slide freely within ways in the bed, and 13 is a rod which connects the blocks 3 and 12, so that the latter partakes of the movements of the former, and this connection may be made adjustable in any suitable and ordinary manner.

Hinged at 14 to the block 12 is the cuttercarriage 15, within the forward end of which is journaled the vertically-disposed cuttershaft 16, which carries at its lower end the cutter 17 and at its upper end a pulley 1S.

19 is a collar secured to the shaft 1G immediately beneath that part of the carriage within which it is journaled, so that it will be clear that said shaft can have no vertical play, owing to the fact that the pulley 18 and col lar 19 confine it in position, as will be clear from Fig. 4.

2O represents pulleys journaled at the rear of the carriage for the purpose presently to be explained.

21 is a rock-shaft journaled within a box 22, secured to the block 12, and carrying at its inner end a cam 23 and at its outer end a lever 24, and 25 is a recess cut within the lower edge of the carriage 15. The swinging of the lever 24 in one direction willcause the cam to operate against the upper wall of this recess, and thereby elevate the carriage, while the reverse movements of the lever will allow the carriage to drop by gravity to its normal position.

Secured to an upright 2b`,which rises from the bed of the machine, is an angle-bar 27, which carries at its lower extremity the foot 2S, that coperates with the cutter. The upper surface of this foot is convex and gradually tapers down to a very thin edge at the extreme forward part, as shown at Figs. 1, 4, and 6. About one-eighth of an inch from the extreme forward edge of the foot the latter is cut away, as shown at 29, this cut-away portion extending entirely through the foot vertically, so as to afford the greatest facility for disposing ot' all refuse incident to the paring operation. This foot during the operation of paring is constantly beneath the curl of the hat-brim, while the cutter pierces the petticoat of the curl from above, so that the foot acts as a sort of anvil to keep the hat well up and steady during the operation of the cutter. As will be `hereinafter explained, the cutter has a rotary movement in a direction opposite to the direction in which the hat is revolved, and the object of revolving the hat in an ovoidal circuit is to keep the oval-shaped brim always in contact against the foot 2S,

while the object of the reciproea'tion of the cutter-carriage is to enable the cutter to traverse the slightly-different ovoidal circuit, due to the fact that the edge of the curl at the sides of the brim is wider than at the quarters or at the ends.

The cutter-shaft 16 is hollow and contains a disk 30 at the end of a spindle 3l, the latter being provided at its upper end with a button 32, between which latter and the end of the shaft is a coil-spring By depressing the button 32 the disk will operate to clean the cutter of all refuse adhering thereto, while the spring will return the disk to normal position. Right in this connection I will say that I prefer to make the cutter separate from the cutter-shaft, so as to facilitate the substitution of new cutters, and,rei"err ring to Fig. 9, would state that it is my intention to provide the cutters with an exteriorly-threaded hub 34, which is driven within the bottom of the hollow shaft, the latter being interiorly threaded at that point for this purpose. 'lhesuhstitution of a new eutter in this instance would he effected by removing the button 32 and withdrawing the cutterand spindle and then afterassembling the spindle through the hub of a new cutter driving the latter into position and'rcplacing the button.

I will now briey refer to the very ordi nary instrumeutalities which I employ for imparting movements to the various parts of my machine Vfrom any suitable source of power.

35 is the primary shaft journaled in the frame of the machine and carrying on its inner end a worm 3G and near its outer end a spur-gear 37, while on the extreme outer end of this shaft ar'e mounted the usual powerpulleys 3S 39. The gear 37 meshes with a small spur-gear 40, carried by a short shaft 41, journaled in the side of the frame, and this short shaft also carries atits outer end an internal spur-gear 42, which meshes with a small spur-gear 43, mounted on a shaft 44, journaled in the frame of the machine, the extreme inner end of this shaft 44 carryinga pulley 45, which is connected by any suitable belt 4G with the pulleys 1S 20, so that it will. be clear that rotary movement will'be imparted to the cutter from the shaft 44. The sizes of these gears are such that the proper speeds and movements desired are obtained, as will be readily understood by a mereinspection of Figs. 1 and 3 ofthe drawings.

Loose around the vertical shaft 7 is a wormwheel 47, which meshes with the worm 3G, this worm-wheel appearing in dotted lines in Figs. 1 and 4S is a hub of this worm-wheel and is pierced in its upper surface so as to provide a series of small holes in circular disposition, as shown in dotted lines at 49.

50 is a clutch-disk splined on the shaft 7 and having depending from its lower side a pin 51 and provided in its periphery with a IOO notch 52.- This disk also carries a friction^= roller 53, which extends slightlyfbeyond theA periphery of the disk.-

54 is a suitable clutch-lever pivoted at 55 to a suitable'bracket 56, supportedon the frame,

the inner end of this lever-having'a'tooth 57,

adapted to engage with the notch 52,V as will` be presently explained. Between this tooth and the pivotalpoint of the lever the latter is inclined upwardly, as shown at 58, so that when the disk 50 revolves the roller 53 will Q ride up this incline, and thereby elevate the y disk bodily, vwhich latter-fis splined on the shaft 7, so as to have a free movement longitudinally thereof.

59 is the hub of the disk 50, and around the shaft7gand conned between this hub and a collar 60, secured to said shaft, is a coil-spring- 6l, which acts to force said disk downwardly,

so that the, pin 5l will either strike against thetop of the hub 48 or engage with one ofA the holes 49l therein.

" 62 is a coil-spring, one end of which is connectedto the frame'of the machine, while the other end is connected with the extreme outer end ofthe clutchlever 54, the'function of this spring being to throwthe Atooth 57 nor' v mally against the disk 50, so that said tooth will engage the notch52 as the disk revolves.V

Y 63 is a hand-lever which is pivoted'at64 to the frame of the machineand-is connected with the extreme outer end of the lever 54 bymeansfof a link 65, lwhose extremities are piv' f oted, respectively, to these-levers.

tion" reverse to'thatV previously described-ff y l From theYforegoingidescription itwill; bev` clear that the actions of the cam-sections 74 75 and the cam 81 will causethe shaft 82, which carries the hat-block, to be swayed in opposite directions,and the character of these cams is such that while the shaft S2 is being revolved the hat will be caused to describe the proper oval, whereby every part of the curled brim will be kept constantly up to a certain predetermined point. Therefore these cams, the parts actuated thereby, and the inclined and gimbal-jointed shafts all contribute toward the accomplishment of one end-namely, the revolution of the hat in the proper ovoidal circuit.

In paring a hat-brim, the parts all being in the position as is shown at Figs. 1 and 2, it will be noted that the extreme inner end of the foot 28 is immediately beneath the curl at the end of the brim, while the cutter 17 extends within the opening 29 in the foot, close to the extreme inner end of the latter, this position of the cutter and foot with respect to the hat-brim being more clearly designated in detail at Fig. 6. As the shaft 7l is revolved the curled portion of the hat-brim will be kept snugly against this stationary foot, while at the same time the cutter will operate to trim off the petticoat or surplus stock from the edge of the curl. As the hat is revolved so that the quarters and sides are brought in position for paring it will be clear that the shaft 82 must be gradually tilted toward the foot, since the quarters and sides gradually increase in height at the curled portions, while the greatest droop of the brim is at the ends. Therefore the cam-sections 74 75 now come into play and effect this gradual tilting, so that the curled brim is kept right up to the foot. As the hat is revolved so as to bring one of the ends vagain in position for paring the shaft S2 will begradually tilted away from the foot, so as to gradually elevate the hat, whereby the foot may alwaysl be in close contact with the curled brim in passing from the sides to the ends. It will be clear that the cutter must gradually travel outwardly in trimming from the ends to the sides of the brim and must gradually retract in trimming from the sides to the ends, be-

cause the curled portionof the brim gradually increases in width from the ends to the sides, and these movements of the carriage which bears the cutterare effected and regulated by means of the cam 6,as hereinbefore explained. In removing the hat after paring the hand-lever is elevated by the operator to throw the brim away from the foot, and the hat is readily removed.

Very frequently it becomes necessary to pare flat-brimmed hats, and in order to do this I have provided a screw 99, which takes into the bottom of the bearings 72 and which affords the sole Support for the shaft 71, which latter, as has heretofore been explained,is capable of a free longitudinal inovef ment in its bearings. By driving this screw deeper in the bearings the shafts 71, 80, and 82 are forced into a higher plane, and when a at-brimmed hat is on the block A the curl of the brim will thereby be brought into proper position with respect to the foot 28. Of course the extreme swaying of the shaft 82 toward and away from the foot will not now become necessary, and therefore I have provided a rack on the side of one of the rods 90, and around this rod I have arranged a sliding pawl 101, so that by moving this pawl out- `wardly and locking it with the rack I can carry the roll 94 away from the cam-sections 74 75, so as to prevent the latter from pern forming their functions against this roller. By operating this screw 99 and the pawl 101 in the manner described I can get the proper adjustments and tilt to the shaft 82, which carries the hat-block, so that I am enabled to pare a flat brim with the greatest facility. Likewise it will be clear lthat I can without any change in the various cams, except the mere adjustment of the cams 74; 75, pare any hat-brim irrespective of the droop at the ends or'the rise at the sides, and this has never before been accomplished by any machine.

I do not want to be limited to any set or sets of mechanisms for connecting my machine with power or for bringing about the proper rotary movements hereinbefore set forth, since in this respect the instrumentalities which I have shown and described are very ordinary and can be changed withlto initially pierce the petticoatof the brim at the starting of the paring operation.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hat-paring machine, the combination of a stationary foot, means for maintaining the curled hat-brim in constant contact with said foot, the rotary cutter, andmeans for advancing and retracting said cutter at predetermined times and in direct proportion to the varying width of the curl ofthe hatbrim, substantially as set forth.

2. In a hat-paring machine, the combination of a stationary foot, means for revolving the hat in a predetermined ovoidal circuit, whereby constant contact is maintained between said foot and the curl of the brim, the cuttersupporting carriage, the cutter journaled in said carriage, means for revolving said cutter, and means for reciprocating said carriage simultaneously with the revolution IOS
