WILLIAM IV. GAMMONS, OF JERSEY CITY, NEW JERSEY.

MACHINE FOR SEWING SWEAT BANDS, ETC., INTO HATS.

Application led May 1*?, 1923.

To all whom t may concern:

Be it known that I, VVILLrAM IV. GAM- MoNs, a citizen of the United States, residing` at Jersey City, New Jersey, have invented certain new and useful Improve.- ments in Machines for Sewing Sweat Bands, Etc., into I-Iats, of which the following is a specification, reference being had to the accompanying drawing forming a part hereof.

This invention relates to machines of :the general character of that shown in Letters Patent of the United States No. 747,963, dated December 29, 1903, and it has for its object so to improve the construction and operation of such machines as to facilitate the placing in sewing position of hats of the present vogue which have brims so bulky that they can be placed in position in machines constructed as shown in said Letters Patent only with difficulty if at all. In general the machine to which the present invention is supplied may be constructed as shown in said Letters Patent, but the feed wheel is so supported upon its driving shaft as 'to permit its upper edge to be tipped forward or away from the machine so as to afford a wider space between the feed wheel and the needle and looper through which a bulky hat brim can be introduced readily. The hat support, instead of being fixed in position, with provision for vertical adjustment, is also supported so that it can move forward to permit the above described movement of the feed wheel. Provision is also made for adjusting the working position of the feed wheel and also for returning the hat support to its proper working position when the feed wheel is returned to its working` position by the action of the presser. The invention will be explained more fully hereinafter with reference to the accompanying drawings in which- Figure 1 shows so much of a machine of the general character of that shown in said Letters Patent 747,963 as is necessary to enable the application of the invention to be understood, the feed wheel being shown in slightly tilted position.

Figure 2 is a detail view in vertical sec- 'tional elevation, showing the feed wheel in its operative position and some of the cooperating parts, the portion of a hat being also shown.

Figure 3 is a detail view in elevation of the parts shown in Figure 2, as seen from sei-iai no. states.

lthe left hand in Figure 2, the hat being removed and the hat support being broken away, as well as a portion of the ring by which the feed wheel is secured on its driving shaft.

Figure 4 is a top view of the parts shown in Figure 2, with the hat removed and the presser arm. in section.

For convenience the same reference numerals are employed herein as in said Letters Patent No. 7 i7 ,963 to indicate like parts.

The machine casing 10 supports and partly enclose-s the working parts of the machine, the driving pulley for such working parts being indicated at 11.

A bracket 12, secured to the lower part of the casing 10 provides a support for the hat support 15, upon which the hat is supported during the stitching of the sweat bandL to the body of the hat, as indicated in Figure 2. In the construction shown in said Letters Patent this hat support, although vertically adjustable` is held rigidly in vertically adjusted position. In the improved machine, however, it is adapted to swing forward, to' a limited extent, upon a horizontal axis. As shown, it is fined to an arm 13 which is hinged, as at 13a, upon an arm 18h, which is secured by screws 1-1 to the bracket 12, the screws passing through vertical slots 15 in the member 13b so as to permit vert-ical adjustment. In order to limit the backward movement of the hat support 16 the arm 13 is provided with an extension 13C, below the hinge 13a, to bear against the rear side of the fixed arm 13.

The feed wheel 18, provided on its working face with suitable teeth 19, is rotated with a step by step movement, in synchronism with the movements of the needle, in the usual manner7 but, in the improved machine1 is so supported on the shaft 20 which carries it, as to permit the upper edge of the feed wheel to swing forward, away from the looper 4.5 and the needle holder 50, so as to provide sufficient space for the introduction of the bulky brim of a hat. As a convenient means for permitting such movement of the feed wheel as it is rotated with the shaft 20,

vthe hub 17 of the feed wheel is formed with a spherical seat or socket as at 17a, to receive the spherical end or ball S202L of the shaft 20, the hub 17 being also formed with a. longitudinal slot 17b to col-operate with a pin 20h carried by the ball member 20a. The hub is further recessed to receive a ring 18a, which Cil may be held by screws 1eb and is formed to fit upon the forward portion of the ball member 20a. By such means the feed wheel 1S is held upon its driving shaft 2O so as to be rotated therewith and is free to swing'A forward at its upper edge, to a. limited extent, as shown in Figure 1, for the purpose stated. ln order that the tilting backward of the feed wheel may be prevented and that the feed wheel may be held in working position with provision for adjustment, an adjusting' screw 13d is threaded in the fixed arm 131 and is arranged to bear against the forward face 0f the forward wheel 18, within the line of the teeth 19, as clearly shown in .Figure 2.

The sweet band and the hat are pressed toward the feed wheel, as shown in Figure Q, by the usual presser wheel 38 which is carried by the hinged presser arm 2S), the hat support 16 being cut away, as at 16, so as to permit the presser wheel 38 to act directly against the sweat band.

1t will now be understood that when the presser wheel has been thrown up and out of the way, the feed wheel 18 can be tilted forward, as shown in Figure 1, so as to provide a space for the introduction of a relatively bulky hat brim. fit the same time the hat support 1G is tilted forward on its hinged joint 13a, aecomn'iodating itself in this manner to the tilting of the feed wheel.

lt will loe understood that the hat, during the operation of the stitcn-forming mechanism, herein shown as comprising the needle and its carrier and the looper, rests upon and is supported by the curved plate 16, that it is gripped at the stitching` point between the presser wheel 38 and the upper edge of the wheel 1%, the primary function of which is to cause the step by step movement of the hat in synchronism with the movement of the needle, and that such feed wheel is so connected, through a form of universal joint, with its driving shaft, which receives the necessary intermittent motion, that the feed wheel is driven positively by its driving shaft and at the same time is capable of the described tilting movement.

lt will also be understood that the machine is adapted for sewing linings into hats as well as sweat bands. lt will further be understood that although the feed wheel is shown in Figure 1 as but slightly tilted, the presser wheel being in position, the feed wheel is capable of being tilted further when the presser is thrown out of position.

l claim as my invention:

1. In a machine for sewing sweat bands, etc., into hats, the combination of stitchforming mechanism, a driving shaft, and a feed wheel mounted upon and driven by the driving shaft and having therewith universal joint in the plane of the wheel to permit tilting of the feed wheel about a horizontal axis and movement of its edge away from the stitch forming mechanism.
