HAT-MACHINE TOOL-COUPLER.

SPECIFICATION forming part of Letters Patent No. 317,426, dated May 5, 1885.

Application filed September 4, 188-1.

. ner as to traverse an uneven or elliptic path in reference to the body of the rotating hat, and in a vibrating coupling device for connecting such tool-carriers, so that both will participate in any movement that may be imparted to either.

In order that different tools may be successively used in such coupled carriers, itbecomes necessary to provide means for adjusting one or both of the carriers or tools in relation to the coupling devices; and thisinvention therefore includes such means of adjustment, as well as a stop for determining its limit.

It also includes means for compensating the lost motion in the coupling device, means for withdrawing the tools from the hat-plate, both for removing the hat and changing the plate, means for supplying air and gas to the heatingburners, and the combination and arrangement of various details of construction. These improvements will be understood by reference to the annexed drawings, in which Figure l is a front elevation of a machine illustrating our invention as applied to a pair of the rocking arms described and claimed in anotherpatent application, No. 142,205. Fig. 2 is a view of the rear part of the frame, showing merely the coupler and the gas-connections. Fig. 3 is aside view of the entire machine. Fig. etis aplan of the same. Fig. 5 is a side view, and Fig. 6 afront view, of the rocking arm detached from the machine, the side view including the nut for the setting-screw, the clamp-nut, the rock-shaft, and one segment, and the front view including the carrierguide and its adjustable supporter. Fig. 7 is a front view of the vibrator-arm and cam-rol- (No model.)

In Fig. 10 the tool carriers and their guides are omitted from the view, and Fig. ll exhibits merely the outer end of one of the carriers, guides, and rectilinear vibrators.

The invention is shown herein as applied to ahat-curling machine provided with two tools mounted at opposite sides of a rotating hatclamp and hat-plate for supporting the brim of the hat; but as the invention is equally applicable to machines for ironing hats, and for trimming, softening, and paring brims, wehave used general terms for the various parts of the construction.

In Figs. 1 to S, inclusive, A is a pedestal of T section, provided with a flange or foot, A, a hearing, A", at the top for the spindle of the hatplate, cam, and clamp, front and rear bearings,

A and A for the driving-shaft, and side eX- tensions carrying bearings E for the rockingshatts. The hat'clamp B is mounted at the top of the pedestal on a spindle, B, in the bearing A It may be made of any desired construction, but is assumed to be of the expansion brow-block class; and a hand-wheel, B is shown in Fig.1 for actuating such block and clamping the hat, either with or without the hat-plate 13 Gears B connect the spindle B with the driving-shaft G, the front end of which extends through the pedestal, with the remainder fitting into and beyond the horizontal bearings A and A, the rear one of which is enlarged to receive a sleeve, 0, which is formed with a pulley, O, at its outer end, and a toothed hub, c, at its inner end.

Between the bearings A A is located a toothed clutch, 0 which is feathered upon the shaft 0, so as to rotate the shaft when the clutch is engaged with the toothed hub c, the 5 pulley O being driven continuously by a belt. (Not shown.) A clutch-lever, 0 is j ointed to the pedestal and to a shifter, G which projects to the front of the machine, beneath the hatclamp,.so as to be readily reached by the oper- IOO ator, the clutch being shown uncoupled in the drawings, as in Figs. 3 and 4. With this construction the driving mechanism is confined entirely to the rear of the machine, and the hat-clamp is so located at the top of the pedestal as to be peculiarly accessible to the operator. The tools 1) shown as curling-irons herein are represented as held by carriers D, which latter are movable to and from the hatclamp in guides 1). These guides are pivoted to rocking arms or holders G, at I), in such manner that the carriers swing freely up and down, so that the tool may rest upon the hat by its weight alone, when desired.

in the drawings two rockingarms are shown, one hinged at each side of the hat-clamp upon rocking shafts E E, the latter beingjournaled in bearings E E, projected from opposite sides of the pedestal A, and the vibrating ends of the arms being extended opposite the sides of the hat-clamp, so as to sustain the toolsin contact with the hat.

The coupling device consists in a pair of toothed segments, F, secured to the rear ends of therocking shafts upon their adjacent sides, with the teeth on the segments interlocked, so that when either of the arms or holders 1's oscillated a precisely similar movement is imparted to the other.

To press the tools toward the hat-clamp, a weight, W, is shown attached to one ofthe segments in Figs. 2, 8, and 4 by a hook, W. With such-construction but one connection is required between the holder and the cam or other oscillating device, and such connection is shown as a vibrator-arm, H, pivoted upon the same center as one of the rocking arms G, and

provided with aroller,H,arranged to bear upon the edge of the hat-plate 13 which plate has its edge suitably shaped to act as a cam, B and impart the desired oscillating motion. The vibrator is furnished with acurved slot, 0/, to fit a clamping-b0] t, a, inserted through the arm G. As the vibrator H has a uniform stroke, while the arm or holder G must hold the tool nearer to or farther from the clamp to suit brims of different widths, means is required for setting the arms in various relations to such vibrator. A setting-screw, a is therefore fitted to a bearing, a and nut a upon the arms G and H, respectively, to set the rocking arm in any desired relationito the vibrator, as may be required to set thctool into an operative position at any desired distance from the center of the hat-clamp. This means of adjustment is for a purpose totally different from the movement of the carrier to and from the hat-clamp in its guide, that movement being intended merelyto clear the tools from the hat and not being necessarily combined with any means for securing the carrier in various positions intermediate to its extremes of movement. The clamp-bolt a serves to bind the holder or arm G rigidly to the vibrator or arm H, after the former has been adjusted for any specific tool or hat, by

turning the setting-screw a To guide the operator in thus setting the holder, we commonly use a graduated scale affixed to the arm G or H, but have not shown the same herein, as we have made it the subject of a separate patent application.

To move the toolcarrier in its guide, we have shown the former provided with a rack, b upon its lower side, adjacent to the pivotal shaft 1), and provide the latter with a toothed pinion, b and with a head adapted to receive acrank, L as shown in Fig. l; or a hand-wheel may be aflixed thereto. The rear end of the carrier is provided with an ad justable stop, b, projecting from its bottom at such point as to strike the guide I) when the carrier is properly set.

With the cur'lingtools shown herein the machine is operated as follows: A hat of known size and width of brim is secured upon the hat-clamp, and both the carriers thrown forward by turning the pinions b and moving the carriers until arrested by the stops 1). The clamp a is then loosened, and the setting screw (0 is turned until either of the tools is correctly set to operate upon the hat-brim. The other tool is then adjusted to operate simultaneously by altering its stop b and movin g the carrier into the required position. \Vhen correctly adjusted, the hat may be curled, and the tools thenbe quickly retracted to remove the hat by turning the pinions b". The provision ofthe stop will then obviously afford the means of restoring the tools to the same operative position for any number of similar hats, provided the tools are unchanged; and should it be necessary to change a tool upon one or both sides of the hat, the stop then affords the means to adj ust such tool correctly and to re set it repeatedly in the same position.

By the coupling of the tools together the vibrating mechanism is not only-simplified, but it is also obvious that the motion of one tool will correspond more accurately with that of the other than if moved by separately vibrating agencies. This is of especial importance in the curling of hats, particularly when the curl is formed by tools acting independently of the hat-brim plate, as the curl is then supported only by the tools and is distorted when the two tools do not follow the same curve.

The coupling of the tools together also secures a great advantage in advancing the tools simultaneously while the machine is in motion, as certain operations like curling may be much more easily and perfectly performed if the action of the tools upon the brim is gradual. Such application of the tools may be made with our construction by loosening the clamp to sufficiently to permit the action of the setting-screw, and then setting the tools into their primary operative position. The curling may then be commenced without tightening the clamp, and the tools may be simultaneously and gradually advanced during the progress of the work until the tools reach their final operative position and the curlingis completed.

In Fig. 1 the tool at the right-hand side is shown in its operative position, and a breaker,

f, hinged to the top of the guide I), is shown in suitable position to co-operate with the curlingiron b. At the left side, however, the stop at the rear of the carrier is shown retracted, and the breaker turned up above the guide to remove the hat. The stop b is thus exposed more clearly to View, and consists, as is also seen in Figs. 3 and 4., of a flat piece notched into the rear end of the carrier, and held thereto by an adjusting-screw, which has a round milled head, 8. The lower end of the stop projects below the carrier, and thus strikes the body of the guide D when the carrier is thrown forward. The sliding carriers, being intended merely to retract the tools when replacing the hats, need not be constructed to draw entirely away from the top of the hat plate B and to secure any further withdrawal of the tools, so as to remove the hat-plate, it is desirable to move the vibrator itself from contact with the plate and hold it back, with the affixed rocking-arm, by a suitable catch attached to the pedestal A. Such catch is shown in Figs. 1, 3, and 4, as a sliding spring-bolt, e, inserted in a boss, 0, upon the top of the bearing E, behind the vibrator-arm H, and the latter is formed with a hole, e corresponding with the bolt when the vibrator is drawn back, as described. When thus drawn back, the bolt is automatically shot into the hole c by a spring, 6", inclosed in the boss 0. The coupler thus operates, when the single vibrator-arm is drawn back, to hold both the rocking-arms backward at once, and to withdraw the tools entirely away from over the hat-plate. The hat-plate may then be readily removed from the clamp, it made detachable, and others of different shape at the edge be substituted, so as to actuate the tools in any desired curve. Aknob, c, is shown fixed to the end of the bolt by which it is pulled back fromthe hole 0 when the machine is again ready for use. The springcatch. may be applied to the vibrator in other ways, as its essential feature is its automatic action when the vibrator is pulled back into an inoperative position.

The term vibrator applied above to the arm H may obviously be construed to cover any means by which the required vibratory movement is given to the tool carriers or holders, and as it is common to actuate the vibrator in various ways in other machines, the arm H or either of the arms G may be vibrated by any other suitable meams that may be preferred To illustrate a modification of the vibrator and coupler, we have shown in Figs. 9, 10, and ll a machine constructed with rectilineal vibrators, to which a segmental coupler could not so readily be attached. In these figures the tool-carriers and pivoted guides are the same as in the other figures; but the holders G are shown as dovetailed slides fitted to fixed ways G upon a bed, A ,at opposite sides of the clamp, and aseparate cam, B is atfixed to the spindle B beneath the plate B The vibrator consists of a bar, H, fitted to one of the holders G by a screw, it", and carrying a roller, 11, in contact with theseparate cam B The holders are coupled together by means of links F and by a central lever, F, pivoted upon the spindle B, the inner ends of the links be ing attached to the opposite ends of the lever, so as to move in the equal and similar manner required for tools applied at opposite sides of the same hat. The weight V is in this construction attached to a cord carried over a pulley, w, and secured to the holder G opposite the vibrator H. The weight thus serves not only to press the tools toward the hatclamp and the vibrator toward the cam, but, as it acts in opposition to the latter, it operates to neutralize all the lost motion in the joints of the links F, and thus secures the most exact coincidence in the movements of the coupled tools. The same effects are secured in the machine with coupled rocking arms by attaching the. weight to the segment F most remote from the vibrator, as shown in Fig. 2. If preferred, the weight W may be replaced by a spring, without, however, securing such uniform pressure.

In practice we make the weight in sections, and apply only enough to force the tools against the felt and bend or operate upon it in the desired manner. The roller H provided upon the vibrator is quiteimmaterial, asits function is merely to reduce the friction, and a bearing-shoe is used in other machines fora similar purpose.

From the above illustrations it will be seen that the coupler, the vibrator, the toolcarrier, and other mechanical elements of ouriuvention may be materially altered in form to perform the same function in dili'ereut machines; and we do not therefore limit ourselves to the constructions shown'hcrein for carrying out our invention.

In the machine shown in Figs. 9, 10, and

11 the setting-screw a is used effectively without any clamp-bolt a, and the latter is not essential to the operation of the arms G and H when united by the screw a as shown in the other figures. TheIterm hat clamp is used herein as an equivalent for any means whatever that may be adapted to rotate the hat in proximity to the tools, and is not therefore specifically described or claimed.

In Figs. 1, 3, and at are shown two treadles, I, pivoted separately to the standard A near its base, at h, and connected separately to the jointed tool-carriers D by means of connecting-rods l; the rods being preferably fitted to the treadles by ball-and-socket joints on to compensate for the various movements of the treadles and carriers, as the latter are applied to and removed from the hat.

By pressure upon the treadle at the latter stage of the curling operation the workman may compress the curl with any degree of force, and thus greatly aid the iron, especially in forming such curls as the Anglsea,

which are pressed down flat upon the hat-brim, to thoroughly break the bend or fold of thefelt. A ball, 1, (shown in dotted lines,) upon an extension, 1 of the treadle lever, behind the fulcrum, may be used, if desired, to balance a part of the weight of the tool or carrier.

By the use of independent treadles the opposed tools may be actuated separately, and

are thus better adapted for performing different operations simultaneously upon the same hat, as required in many processes.

In Figs. 1 and 12 is shown a gasjet of special construction, adapted to project a flame into theheated tools from some external point. The construction consists in anozzle, f, screwed into a socket, g, each of these parts being formed with a separate pipeconnection, cl, and one of them being provided with a shank, g, for attaching the jet to the tool holder or carrier adjacent to the flame-opening in the iron. The shank maybe formed at any angle with the pipe-connection as maybest suit the location of the flexible tubes, g (Shown in Figs. 1, 2, and 3.) The employment of the shank is shown in Fig. 1, where the jet is shown secured thereby to the carrier D in the rear of the curling-iron I), and the flexible pipes areindicated as projecting at the rear of the jet. The socket consists in a chamber into which the gas-pipe connection opens, an d is formed with a contracted outlet, 9 in which the nozzle is centered. It is also formed with a threaded opening,'t', opposite the outlet, for the attachment of the nozzle, the point of which is set even with the mouth of the outlet g The central bore of the nozzle is penetrated by the air-connection, so that an airblast may be forcibly projected from the nozzle into the midst of the gas which issues fromv the annular space in the socket about the nozzle. W e find that this construction of jet produces a smokeless flame like a blow'pipe, and that the iron is thus much better heated than when the burner is inserted within it.

We are awaretha-t a gas and air jet is old, and therefore claim only the particular construction herein described.

We are aware that it is common to change the form of a brow-block or of a mold for curling and shaping hat-brims by mechanism which operates to expand or contract the opposite parts equally and simultaneously, and that similar mechanism has been used to press opposed dies or tools toward a mold. We do not therefore claim, broadly, the means for connecting or moving two opposed tools; but, having fully shown the nature of our invention herein, it will be observed that it differs from any previous construction in providing a vibrating coupler adapted to operate vibrating tools and tool-carriers, and that it thus affords the means to dispense with one of the cam rollers or vibrators heretofore used in machines having two tool-carriers vibrated at opposite sides of the same hat. It is therefore restricted to a vibrating coupler applied to vibrating toolcarriers, the vibrating motion of the latter being intended to traverse the tools in an elliptical or irregular path about a rotating hat, and the invention. being therefore claimed in combination with a rotatin g hat-clamp. The rocking arms are also claimed herein as vibrating rocking arms.

We are aware that machines have been heretofore patented in which a rotating hatclamp is combined with various forms of tool carriers, holders, and vibrators, and do not therefore claim such parts, broadly, as our invention, but only the novel combinations or constructions herein described.

We have restricted our claims herein to the stop I) and catch 6, exclusively, in combination with a pair of holders or carriers coupled together, as we have claimed the same otherwise in another patent application, No: 142,205, of E. Tweedy and Geo. Yule, and Nos. 142,202 and 142,204, ofGeo. Yule.

We have also claimed in other pending apbination, with a brim-supporting plate, of a curling-tool resting freely upon such plate, and operated by a vibrating holder and toolcarrier.

It is obvious that certain parts of our invention may be used without the others, and, as we havefully described their separate functions above, we claim the same in the follow- 1ng manner:
