Patented Jan. 19, 1909.

Original application filed July 9, 1902, Serial No. 114,875. Renewed December 12, 1907, Serial No. 406,201.

Divided and this application filed June 2'7, 1908.

T 0 all whom it may concern:

Be it known that 1, CHARLES A. DEAR- BORN, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Feeding Mechanism for Hat- Sweat-Sewing Machines, of which the following is a specification.

The present application constitutes a division of the application, Serial No. 406,201, filed by Charles A. Dearborn on December 12, 1907, for Letters Patent No. 894,819, dated August 4, 1908 for improvements in sewing machines.

The invention relates to improvements in feeding mechanism for hat sweat sewing machines, and consists in the novel features, arrangement and combinations of parts hereinafter describedand particularly pointed out in the claims.

I present my invention in this application as embodied in a hat sweat sewing machine comprising the needle mechanism, looper actuating mechanism, a looper, and novel means for feeding the hat along the point of sewing, said feeding means constituting my present invention and comprising as an essential feature, a positively driving circular ring or frame supporting the hat and effecting its intermittent feed motion along the point of sewing. The circular feed ring or frame for feeding the hat will be driven from the driving shaft of the machine, as by a pawl and ratchet mechanism, and preferably the said feed ring or frame will be supported within the upper edges of a tiltable but otherwise stationary circular frame equipped with a suitable handle by which it may be tilted, and a spring for pressing the edge of the feed ring or frame in a direction against the presser foot.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:-

Figure 1 is a side elevation of a hat sweat sewing machine constructed in accordance with and embodying the invention; Fig. 2

is a top view of same; Fig. 3 is a side elevation of same, this figure showing the opposite side of the machine to that illustrated in Fig. 1 and Fig. 4 is a detached sectional Serial No. 440,739.

view through a portionof same on the dotted line 44 of Fig. 3.

In the drawings 15 denotes the general frame of the machine, this frame comprising the base 16 having at its rear end the integral member consisting of the vertical standard 17 and forwardly extending horizontal arm 18, and said base 16 having at its front end the forwardly projecting segmental arms 19, 20, at whose forward ends are the vertical standards 21, 22, which at their upper ends receive the screw trunnions 23 supporting upon their inner ends the circular frame 24, which is capable of having a tilting or rocking motion upon the said trunnions 23 but is otherwise stationary.

The frame 24 supports and guides the circular feed ring 25, which has a toothed upper edge to engage the hat, and an annular projecting shoulder 26 which rests upon the upper edge of the frame 24 and is formed with ratchet teeth throughout its entire eX- tent. The lower edge of the feed ring 25 sets within the u per edges of the frame 24, while the said shoulder 26 rests upon the upper edge of said frame, and the feed ring 25 which is adapted to rotate upon the upper edge of the frame 24, is held in position upon the latter by means of the lips 27 (Figs. 1 and 8), which are fastened at their lower ends by screws to the frame 24 and at their upper ends pass around the annular shoulder 26 and enter an annular groove 28 formed in said ring 25 above said shoulder. The lips 27 by passing over the annular shoulder 26 prevent the ring 25 from escaping upward from the frame 24 but do not interfere with the intermittent rotation of said ring upon the upper edge of said frame.

The feed ring 25 receives its intermittent motion from the driving shaft 29 through the eccentric 30 thereon, the eccentric rod 31 (Fig. 3) connected at its upper end with said eccentric and at its lower end pivotally secured to the rod 32, the said rod 32 and the pawl 33, the latter being carried by the eX- tension 34 at the front end of said rod 32 and being in engagement with the ratchet teeth on the annular shoulder 26 of said feed ring 25. The rod 32 extends frontwardly from the eccentric rod 31 and at the lower portion of its front end is formed with the extension 35 which is equipped with a bearing hub 36 mounted upon the horizontal stud 37. The eccentric rod 31 is given a substantially vertical movement from the eccentric 30, and the rod 32, is, by means of the rod 31, given an oscillatory or rocking motion on the stud 37, thereby causing the pawl 33 to have a forward and backward movement and enabling said pawl on its forward thrust to impart a limited rotary motion to the feed ring 25. While moving rearwardly the pawl 33 will slip over the ratchet teeth on the ring 25, and at such time the said ring will be prevented from having any reverse movement by means of a locking dog or pawl 38 pivotally secured upon the upper end of the vertical standard 22. The pawl 33 is secured upon the upper end of apin 39 carried by the extension 34 of the rod 32, and upon this pin 39, as shown in Fig. 3, is provided a spring which acts to yieldingly press the engaging edge of the pawl 33 against the ratchet teeth of the shoulder 26. During the rotation of the driving shaft 29 the feed ring 25 is, by the means just described, given an intermittent rotary motion upon the upper edge of the circular frame 24 for the purpose of feeding the edges of the hat and hat sweat to the sewing mechanism.

Upon the front end of the horizontal arm 18 of the machine frame is secured a stationary presser-foot 40 having a concave lower end or lip 41 upward against which the inner or rear edge of the feed ring 25 presses, said feed ring 25 having a yielding or spring tension upward at its inner or rear edge against the said presser-foot owing to the interposition of the coiled spring 42 between the base of the general frame of the machine and thehandle 43 (Fig. 1) fastened to the circular frame 24. The coiled spring 42' is held upon a pin 44 which extends freely through the handle 43, and the said spring is permitted to yieldingly press the inner or rear edge of the feed ring 25 upward against the presser-foor because of the fact that the circular frame 24 su porting said feed ring is pivotally mounted between the upper end of the standards 21, 22. In the employment of the feed ring 25 the crown of the hat is pressed downward within said ring and the circular frame 24, and the brim of the hat is folded down upon the exterior sides of the said feed ring and frame, the then upper edges of the hat along the line of the inner edge of the brim and the outer edge of the hat sweat at the rear edge of the feed ring 25, being by means of the spring 42, held up against the concave lower ed e of the li 41 of the presser-foot 40. In or er to ena le the convenient a' plication of the hat to the feed ring 25, elow the presser-foot 40, I mount the circular frame 24 a pivotal manner and provide said frame wit the handle 43, the latter enabling the operator to ress downward the inner or rear side of t e frame 24 and ring 23, whereby a substantial clearance is secured between the upper edge of the ring 25 and the lower end of the presser-foot 40 for the introduction of the hat below said foot. The spring 42 exerts firm upward pressure against the frame 24, but the force of this spring may be readily overcome by the operator owing to the fact that the handle 43 is of substantial character and extends rreawardly to a sufficient extent to enable, when pressure is applied thereupon, the convenient lowering of the inner or rear end of the frame 24 against the stress of the spring 42.

The driving shaft 29 will be equipped with a usual belt and hand wheel 45, the aforesaid eccentric 30 the eccentric 46 from which the rock shaft 47 will be actuated, a balance weight 48 in the form of a half disk, and an oblique eccentric 49 receiving the eccentric strap 50 and cooperating therewith to impart the proper movement, as hereinafter explained, to the looper 51. The belt and hand wheel 45 and balance weight 48 are usual in this art and require no special description. The eccentric 46 is rigid on the end of the driving shaft 29 and is connected by. a strap 52 with the longitudinally reciprocatory rod 53 whose front end is pivotally connected by a pin 54 with the lower endof a crank arm 55, whose upper end is rigidly secured upon the end of the rock shaft 47, the purpose of the eccentric 46, rod 53 and crank arm 55 being to impart the proper rocking motion to the shaft 47 and the parts connected therewith. The shaft 47 is mounted in bearings at the front end of the arm 18 of the general frame of the machine, and upon its left hand end the said shaft 47 carries the said crank arm 55, while upon the right hand" end of the said shaft 47 is secured the crank arm 56 carrying the needle 57 which preferably will be curved, as in Fig. 1. The needle 57 under the rock ing motion of the shaft 47 will perform its known motion, carrying the thread back and forth through the fabric.

The looper 51 is carried in the forward end of the looper rod 68, whose other end is pivotally connected with the eccentric'strap 50 on the oblique eccentric 4 9, and the forward portion of the looper rod 68 is: supported on the outer end of a crank pin 74 carried by the crank arm 75 (Fig. 2) which is adapted to have a swinging or oscillatory motion sothat the looper rod may perform itsforward and backward motions under the influence of the eccentric 4-9. The connection of" the looper rod 68 with the crank pin 74: is by means of a ball and socket joint, whereby said rod'i's permitted to have the proper angular movement under the influence of the oblique eccentric 49. The present invention is not limited to any special needle and loo er mechanisms, and hence a more detaile explanation of 122 these parts of the sewing machine illustrated is not necessary herein.

The special sewing mechanism illustrated in the drawings is shown and described in the aforesaid Letters Patent No. 894,819 granted August 4:, 1908 to Charles A. lJearborn.

The present invention, as will be understood from the foregoing description, pertains more essentially to the feeding mechanism of the machine, and this feeding mechanism is not limited to the employment therewith of any special sewing mechanism.

he operation of the machine hereinbefore 'oescribed will be largely understood from the foregoing eXple rations, and hence but a brief further reference to the operation of the machine will be necessary. fi hen the machine is employed for sewing linings or sweat bands into hats, the crown of the hat will be pressed downward through the fee-d ring 25 and supporting frame 24 and the brim of the hat will be turned downward over the outer edges of the said ring 25. In order to facili tate the introduction of the hat to the feed ring 25 and below the ii 41 of the presserfoot, the operator will ti t the said ring and the frame 24 downwardly and rearwardly by pressing upon the handle 43 and compressing the spring 42, and after the hat has been introduced to position the spring 42 will maintain in a suitable manner the firm relation of the hat to the feed ring and presser-foot. The hat being in position and the machine being set in motion, the needle 57 will be caused to perform its motion from the driving shaft 29, rock shaft 47 and needle carrying arm 56, while at the same time the oblique eccentric 49 will drive the looper rod and the ordinary eccentric 30 will, through intermediate mechanism, impart an intermittent feed motion to the ring 25 and the hat held thereon. The feed ring 25 is driven by means of a pawl 33, and this pawl is given its motion from the eccentric 30, the rod 31 and rocking arm or frame 32. The movement of the sewing needle is not of unusual character.

The feed ring 25 having a toothed or roughened edge or surface to engage the hat and bein positively driven from the driving shaft of the machine assures in a convenient and certain manner the correct feeding of the hat to the sewing needle, and I regard the positively driven feed ring 25 for supporting and feeding the hat as of great importance and novel.

I am aware that hats have been supported within circular frames, but in accordance with my invention the ring 25 not only supports the hat but is a positively driven feed element for the hat. By providing the feed ring with the toothed or roughened edge or surface for engaging the hat, the latter is compelled to travel with the, ring, it being the purpose of this portion of my invention hat the ring and hat shall travel together i and that the hat shall not travel independently of the ring or the ring independently of the hat.
