SPECIFICATION forming part Of Letters Patent No. 552,942, dated January 14C, 1896.

Application filed January 16, 1893. Serial No. 458,558. (No model.)

To @ZZ when?, it may concern.-

Be it known that I, GEORGE W. Weiss, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Sewing-Machines, of which the following is a specification.

My invention relates to an improvement in sewing-machines, and more particularly to sewing-machines for sewing sweat-bands to hats.

The object of my invention is to provide a machine by which a hat-sweat can be sewed into a hat (stiif or pliable) Without dificulty, to provide means for the proper guida-noe and manipulation of the sweat-band, and to protect the hat or hat-brim from the operating parts of the machine.

A practical embodiment of my invention is represented in the accompanying drawings, in Which- Figure l is a vien of the machine in longitu dinal vertical section, partly in elevation. Fig. 2 is a view in end elevation with the facecap removed. Fig. 3 is a view in detail of the mechanism for producing the needle-feed. Fig. i is a vertical transverse section through line x a: of Fig. l, looking toward the needle end; and Fig. 5 is a top plan vien7 of the base and Work-table, the standard and overhanging arm with the mechanism supported thereby being removed.

The bed-plate consists of a broad portion A farthest from the needle and a. narrow horn or neck portion A at the end nearest the needle. A curved cloth-plate B is secured to the extreme end of the horn A and is elevated therefrom. A looper-driving shaft C extends along' Within the horn A' and gears with a short counter-shaft C carrying a looper c on its inner end beneath the needle-slot h in the cloth-plate B. An adjustable Workguide D is elevated from the bed-plate and is secured to a slide E on the bed-plate A, and extends thence along and is spaced from the horn A to a point over the cloth-plate B in proximity to the needle-slot o. At its extreme end the guide D is provided with a transverse groove d, preferably formed by curving its extreme end, and this groove is adapted to receive and guide the reed edge of the sweat-band and hold it in proper position with relation to the needle while the reed covering and sweat-band are being sewed into the hat. The reed edge of the svs-'eat-band is that edge along which a small reed is commonly inserted in the band to make a rounded iinished edge, and the japanned-cloth strip united along one of its edges With the under side of the sweat-band projects past the reed edge to receive the stitches which unite it with the hat, the sweat-band when turned into the crown of the hat serving to conceal both the cloth strip land stitches.

The slide E is guided by screws passing through elongated slots in said slide and fixed in the bed-plate, and said slide moves suiiiciently to advance the free end of the guide inwardly to the inner edge of the cloth-plate B for inserting the sweat-band beneath the guide, between it and the horn A". A lever F pivotally secured to the bed-plate at f and loosely connected with the slide E by passing freely through a slot therein is provided with an operating-knob f". A retracting-springj22 is connected with the under side of the bedplateand to an extension of the knob f of the lever F to throw the latter into a normal or retracted position, and the said lever F and hence the guide D is held in advanced or operative position against the tension of the springf2 by a stop f3 on the base.

A hollowT supporting-standard G With an overhanging arm G rises from the base portion A. The main drive-shaft H is mounted in the arm G and carries a pinion h which gears With a pinion hf on an upright shaft h2, Which also is geared With the looper driveshaft C.

The needle is denoted by l and is carried by a needle-bar il, reciproeated vertically by a crank-pin h3 on a cam-disk h4 fined on the shaft H. The needle-bar is vibrated to feed the Work by an angle-lever K operated by a lever 7o controlled by the cam-disk 7b4.

The needle-bar controls the movements of the presser-foot bar L to the extent of releasing the pressure at the moment of feed by means of an intervening feed-bar M connected with the needle-bar and presser-foot bar in a Well-known manner.

The needle-bar, feed-bar, presser-'foot bar and their connecting mechanism are mounted IOO in a box head-piece N, swiveled on the driveshaft H by means of a hub or neck n, the end of which iits within a socket g in the end of the overhanging arm G.

rI"he drivepulley h5, removably secured on the shaft H at one end ci' the frame and the cam-disk 714, secured on the end of the said shaft within the box head-piece N, serves to hold the head-piece in position with the end of its neck within the socket g. That portion of the neck n which enters within the socket g is provided with notches fn. in its periphery for locking the head N in the desired adj ustment for operating upon the work and for inserting and removing the work. A springactuated catch O is mounted in the wall of the socket g in position to extend through the wall of said socket and into the notches n/ to effect the locking of the head.

A guard-piece P, Fig. et, secured at its upper end to the under side of the head N, extends downwardly parallel with and along the inner side of the needle-bar and needle to a point within a short distance of the work-table B,to separate the hat-brim from unintentional contact with the moving parts. The guard is also provided with an extension arranged at a right angle to the main part and projecting in front of the needle and needle-bar, as shown in Fig. l. It will thus be seen that the hat brim or other part of the hat will be thoroughly protected from the operating parts of the machine above the bed-plate during the operation ot' sewing.

In operation when it is desired. to adjust the hat and sweat-band for attaching the latter to the hat, the head N may be first swung around to carry the needle off to one side of its normal position. The guide D is then thrown inwardly to bring its free end at the edge of the cloth-plate. The sweat-band is then insertedbetween the guide D and the horn A with its reed edge on the cloth-plate B in proximity to the needle-slot and with its covering-strip over the needle -slot. The

guide D is then shifted outwardly to bring the groove in its end on the reed edge of the sweat-band. The hat may then be inserted in position by passing its brim through the free open space between the head N and the cloth-plate B to bring its body portion adjacent to the brim where the seam is to be made over the needle-slot, and the head N may then be swung back into its normal position with the needle over the cloth-plate, and the seam is then formed. When the seam is completed` the hat with its sweat-band attached thereto may be removed from the machine by again turning the head N off to one side and shifting the guide D inwardly.

Vthile I have shown in the present instance a rotary looper-hook for forming the stitch, a reciprocating shuttle of well-known or approved construction might be utilized it it were found desirable to form a lock-stitch instead of a chain-stitch.

l. The combination with the bed-plate having a narrow horn-extension, of a throat-plate secured to the outer end of the horn and elcvated therefrom, a slide supported and guided on the bed-plate adjacent the inner end ol' the horn, a guide carried by said slide at an elevation from the bed plate and extending lengthwise of, and spanning the distance between, the slide and throat-plate, means for normally holding the guide retracted, means for shifting the guide, and means for holding the guide in operative position; substantially as described.

,2. The combination with the bed-plate having a throat-plate secured thereto and elcvated therefrom, of a slide supported and guided on the bed-plate at a distance from the throat-plate, a guide carried by said slide at an elevation from the bed-plate and spanning the distance between the slide and throatplate, means for normally holding the guide retracted, a lever pivoted to the bed-plate and loosely connected to the slide for shifting said guide, and means for holding the guide in operative position; substantially as described.

3. In a sewing machine, the combination with the head thereof carrying a needle bar and needle, of a needle guard secured to and depending from the head adjacent to an d parallel with the bar, and comprising two plates arranged at a right-angle to each other and disposed respectively in front, and at one side. of the needle; substantially as described.

GEORGE IV. IVEISS.
