MACHINE FOR SEWING SWEAT-BANDS IN HATS.

SPECIFICATION forming part of Letters Patent N o. 477,750, dated June 28, 1892. Application tiled May 27, 1891. Serial No. 394,301. (No model.)

To all whom t may concern:

Be it known that I, WELCOME I. GAMMoNs, Jr., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Sewing Sweat-Bands in Hats ,1 and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of sewing-machines designed especially for sewing sweat-bands in hats and caps; and it has for its general object to provide a machine of a construction adapted to form the whip-overstitch or the zigzag7 or overseam stitch disclosed in my prior application iiled February 26, 1891, Serial No. 382,972.

To the thorough attainment of the foregoing general object the invention consists in the peculiar construction,novel combination, and adaptation of certain parts hereinafter pointed out, among which are the friction- Wheel and guide-wheel adapted to normally clamp and continuously feed the hat and band through the guide-plate, one of which wheels is capable of lateral movement with respect to the other, whereby the hat may be readily inserted between the same, the mechanism for laterally moving clamping guidewheel, the flexible or resilient plate supporting the friction feed and guide wheels, and mechanism for vertically reciprocating the outer end of said plate, whereby the needle takes alternately through the band and hat and over the edges of the same, and the support for the hat adapted to be adjusted with respect to the friction and guide wheels and comprising an adjustable peripheral band adapted to receive and support different sizes of hats.

The improvements will be fully understood from the following description and claims when taken in conjunction with the accompanying drawings, in which Figurel is a front elevation of my improved machine complete, a hat and sweat-band being illustrated in a position to be sewed. Fig. 2 is a top plan View of the same. Fig. 3 is a detail top plan view of the resilient plate carrying the feed-wheel and the slide-plate carrying the guide-wheel, together with aportion of the lever connected with the latter plate and adapted, in conjunction with other levers, to manipulate the same. Fig. et is a detail perspective View of the levers adapted to manipulate the slide-plate. Fig. 5 is a perspective view of the needle-plate removed; and Fig. G is a similarview of the same,I looking at the lower edge thereof.

In the said drawings similar letters and numerals designate correspondingparts throughout the several views, referring to which- A indicates the bed-plate, and B the overhanging arm upon which the horizontal power-shaft C is journaled. Fixed upon one end of the shaft() is the ordinary band-pulley D, and on the opposite end of said shaft is fixed a vertically-disposed beveled gear-wheel E, which meshes with a horizontally-beveled pinion F, fixed upon the upper end of a vertically-disposed rotatable shaft G, presently to be described. The wheel E is twice as large as the wheel F, so that the latter makes two revolutions while the former makes one, the purpose of which will become apparent presently.

Fulcru med on a Vertical post II, rising from the hanger-arm B, is a lever I, to the forward end of which is pivotally connected one end of a pitman J, the opposite end of which is connected to a crank-pin on the pinion F, through the medium of which the pitman and lever are actuated for a purpose presently set forth.

.Iournaled at the forward end of the hangerarm B is a transversely-disposed rock-shaft K, which carries a crank L at its rear end, which is pivotally connected to one end of a pitman M, which in turn is pivotally connected at its opposite end to the rear end of the lever I, from which a reciprocatory motion isimparted to the said rocking shaft K, upon the forward end of which is xed theneedle-carrying arm N, in the lower end of which the curved and eyed needle P is suitably fixed. The needle-arm is adjustable longitudinally on the shaft K to permit the needle to be properly adjusted to the looper. The hub of the crank L serves as a stop against the rear bearing of the shaft to prevent a lon` gitudinal forward movement of the latter, .and

ICO

a coiled spring K on the shaft between the rear bearing and aremovable collar holds the shaft in proper position.

Through the medium of the construction thus far described it will be readily seen that the needle-carrying arm is vibrat'ed by the oscillations of the shaft K, and the vertical shaft G, which carries the looper, is rotated from the powershaft C. Fixed upon the power-shaft C at an intermediate point in the length thereof is a disk R, which is provided with cams at intervals upon its periphery, designed to engage the ordinary thread-controlling lever S for taking up the slack in the thread.

Attached at one of its ends by screws or the like to a platform extending from the upright branch of the hanger-arm B is the resilient or spring-metal plate T, which is reduced on its forward side adjacent its free end for a purpose presently set forth.

Journaled on a short shaft dependingfrom the plate T, adjacent the free end thereof, is a horizontal friction feed-wheel U, which is milled upon its periphery for obvious reasons, and is provided upon its upperside with rackteeth designed to be engaged by a pawl, whereby the wheel is turned and the work fed a slight distance at each depression of the said plate T.

Pivotally connected to the front side of a branch V, depending from the hanger B, is the pawl WV, which is provided at its forward end with a depending branch,\vl'iich engages the ratchet-teeth on the upper side of the Wheel U for the purpose described. The depending branch V is provided with a vertical bore, as illustrated by dotted lines in Fig. l, and in this bore is seated a plunger X, which bears at its lower end upon the plate T, and is provided at its upper end with a friction-roller, which is designed to be engaged by a cam Y, xed upon the shaft C, whereby at each revolution of said shaft the plate T will be depressed, whereby it will be seen that the reciprocating needle will alternately take through the sweat-band and hat and over the edges thereof. Vhen the plate T is depressed by the cam Y and plunger X, it carries down with it the guide and feed wheels A U. The pawl XV follows the feedwheel, the point moving in the arc of the circle of which the pivot of the pawl is the center, the said movement being sufficient to enable the pawl to engage the next ratchet-tooth of the wheel. Then when the plate T and its connected parts rise on the recession of the cam Y the pawl will be turned upward on its pivot, its point will swing forward, and the feed-wheel will be moved one step.

As illustrated by broken lines in Fig. 3, the plate T is provided with longitudinal slots for the reception of screws d a, which pass through the same and screw into the plate Z, and the latter is also provided toward its front end With a slot for the reception of the screw b, which screws into the plate T. These screws machine. .spring 2O will return all the parts to their serve the double purpose of holding the two plates together and guiding the plate Z in its reciprocating movements. Evidently the said slots might all be formed in one plate and the sore-ws a d and l) screwed into the other.

The plate Z is capable of being reciprocated longitudinally on the plate T, the limit of movement being determined by the length of the slots through which the screws a d l) pass, and it is held normally in its retracted position by a spring 20,one end of which for convenience is att-ached to one of the screws a and the other end to a screw or pin cc', projecting from the under side of the plate T. At its forward end the plate Z is recessed, as shown, and is provided with an vangular bran ch, upon which is mounted a guide-wheel A', which rests in alignment with the-wheel U and is adapted to clamp the hat and sweatband against the periphery thereof.

Fulcrumed at one end to the upright branch ot' the hanger-arm is a hand-lever 2, which is provided with an angular branch 3, to which is connected one end of a coiled retractingspring 4, which is connected at its opposite end to the upright branch of the hanger-arm adjacent to the bed-plate. At a suitable point upon the inside of the lever 2 is formed a lug 5, upon which rests one end of an arm 6which is notched, as shown, and embraces the lever. The upper end of the arm 6 bears and slides against the lower side of the plate T and it is provided, as illustrated, with a lateral branch to receive one end of alever 7, which takes up through alongitudinal slot in the plate T and a square opening in the plate Z, which latter plate it serves to move forward, as will be presently described. At

l its upper end thelever 7 is pivotally connected i to the hanger-arm B, and it will thus be seen that by throwing the lever 2 to the left, as viewed in Figs. 1 and 4, the plate Z and its guide-wheel A will also be moved to the left,

carrying the said guide-wheel away from the feed-wheel U to permit the hat and sweat-band to be conveniently put into or taken from the Then the lever 2 is released, the

normal positions.

Connected in a suitable manner to the bedi plate A at a proper point below the guide an-d feed wheels is a slotted horizontal bar 8,which is designed to receive the standard 9 of the hat-supporting frame. Connected to the upper end of the standard 9 are the radial branches d of the hat-supporting frame, upon .the outer ends of which the vertically-disposed spring-band l0 is mounted and secured.

" One of the ends of the band 10 is preferably recessed, as shown, and in the reduced portion formed by said recess are longitudinal slots 1l, through which studs or screws eX- "tend from the other end of the band, and rthese studs or screws may carry nuts 12,

whereby said band may'be increased and reduced in size to receive hats of various sizes,

IOC

IIO

and by placing or folding the hat over the edge of the crown-band the operator is enl abled to sew an even line.

It is obvious that in practice the ends of the crown band or holder l mightI be adj ustably connected ina manner other than by thelugs and slots, and I therefore do not care to conline myself to the construction set forth. By the provision of the construction described it will be perceived that the standard 9, carrying the crown-band, may be readily adjusted in the slotted bar 8 with respect to the guide i and feed wheels to hold hats of different sizes in proper position to be sewed.

The needle-plate 12, which is suitably fixed by screws or the like upon the outer end of the hanger B, rests so that its lower edge occupies a plane slightly above the friction feed and guide wheels and the play-line of the laterally-movable needle.

Attached by screws to the front side of the plate 12 is a plate 13, which extends almost to the lower edge of the plate 12, and is provided with a depending flange which is flared slightly out-ward and extends below the edge of said plate 12 and' affords a way for the sweat-band, whereby the depth of the stitching is regulated.

Attached to the rear side of the needleplate 12 is a plate 14, the lower edge of which rests in a plane slightly `below the edge of the needle-plate and serves as a keeper for the folded edge of the hat, which rests against the lower edge of theneedle-plate, and is thereby retained in a `slightly-lower plane than the sweat-band, as is desirable. The plate 13 is provided in the lower edge of its depending flange at a suitable point with' a recess l5, and the plate lll is provided adjacent its lower edge with aslot 1G for the passage of the needle.

Upon the lower end of is fixed the looper 17.

In operation the hat and sweat band are mounted, as has been t described, and are clamped between `the friction feed and guide wheels,so that the band will rest between the flange of the plate 13 and the needle-plate, while the folded edge of the hat will rest beneath the-needle-plate and against the plate 14. The machine is then started, when the needle takes through the leather and the hat; but by reason of the needle being curved up wardly it passes upwaid in a slanting direction after passing through the sweat-band, its path being through, the edge of the fold, so that the stitches will not show on the outside of the hat-body. .lVhen the needle reaches the end of its inward stroke, the looper 17 engages the thread and takes an inwardly-directed loop therefrom, and the needle on its the vertical shaft G return stroke carries the" thread through the hat and band in an opposite direction to the first-named stitch. At the beginning of the next inward stroke of the needle the plate T will be depressed, when the needle will take over the hat and sweat-ban d and through the inwardly-directed loop. The thread is then engaged by the looper 17 and another loop is formed. The needle then returningcarries back one of the branches of the latter loop, after which it is carried back and over the said latter loop and then through the folded edge of the hat, so as to form a second loop, and so on until the band has been secured.
