like, and allow the proper amount of bat brim to be used for that purpose.

A further object of the invention is the provision of a guiding means for proper alignment of the hat in the machine while the welt is being sewn.

The present modes of stitching hat welts b machines using either a lock stitch or cli ain stitch has proven unsatisfactory due to the fact that a chain stitch for this purpose is unsightly and the lock stitch as at present applied does not hold the welt edge firmly enough causing the hat brim to have an uneven appearance when rolled into shape. It also happens when employing the present method of sewing hat welts that the welt edge is weakened and even often torn by the needle due to the fact that the needle first penetrates the turned over portion or welt of the brim and then into the body of the hat brim proper.

The present invention on the contrary con sists in part of passing the threaded needle at substantially right angles through the body of the brim and thence into the welt thus assuring a firm hold of the stitch on the parts sewn.

Other objects and novel features of the invention will be fully described as the specification proceeds.

In the drawings forming a part of this specification Figure 1 is a side view in elevation of a sewing machine with my improvements applied thereto.

Figure 2 is a fragmental top plan vlew of some of the parts shown in Fig. 1.

Figure 3 is a top plan view of the stitching end of the machine.

Figure 4 is a detail view of the guide and adjusting means, and

Figure 5 is an enlarged detail view of the welt edge showing the needle penetrating through the body end of the hat brim.

Referring to the drawings in detail, indicates a head of a sewing machine of the Pryx seam sewing type provided with a.

drive pulley 11 on a shaft 12having a bevel gear 13 in mesh with a bevel gear 14 on a shaft 15 provided at one end thereof with needle thread feeding mechanism and at the other end with shuttle operating mechanism not shown as it forms no part of this invention. A bracket pivotally secured to a base member 21 on studs 22 is provided with a disc 23 pivotally secured to an arm 24 thereof, the said disc acting as a rest for a hat welt 25 passing between a feeding head 26 and a coactingbeaming head 27 secured to an arm 28 of the bracket 20. The bracket 20may be' partly rotated forwardly against the tension of the spring 29 exerting a tension against an arm 30 loosely mounted on one of the studs 22 for the insertion of a hat with its welt on the disc 23 and between the heads 26 and 27. On a plate 31 fixed to a post 32 through which passes part of the usual shuttle mechanism 33, there is secured by a screw 34 a plate 35 carrying at its outer end an adjustable welt regulating and guide member 36. The welt regulating and guide member 36 is secured to the plate 35 by screws 37 passing through clearance holes 38 in the plate 35 and threaded into the member 36. To adjust the member 36 to accommodate a hat of a lesser thickness than has already passed through the machine the screws 37 are loosened a predetermined distance and a screw 39 passing through the plate 35 is tightened thus reducing the space between the hat rest or disc 23 to properly accommodate the said hat. If it is desired to reduce the amount of hat brim used, or to sew closer to the welt edge, the outermost screw 37 is loosened and the center screw 39 is tightened causing the member 36 to swing inwardly on the innermost screw 37 as a pivot and forcing the brim of the hat downwardly and the needle 40 will penetrate the said brim at a higher level thus reducing the space between the stitches in the brim and the edge of the welt. For the opposite effect the innermost screw 37 is loosened and the member 36 will swing inwardly on the outer screw 37 when the screw 39 is tightened. The entire gauge or guide may be swung in and out of operating position by loosening the screw 34. To prevent the hat from leaving the disc 23 prematurely, a guide member 41 is secured to the plate 31 and asses over the hat welt parallel to the :fiember 36 and on the other side of the nee- From the foregoing it will be seen that I have provided a machine in which hat welts are stitched through the body of the hat brim, thence through the welt edge, the needle assing through the brim at right angles thereto, which is the most satisfactory manner, thus insuring a tight stitch showing only at the welt edge and concealed in the brim. I have further provided an adjustab'le member in connection with such a. machine to regulate the position of the stitching in relation to the brimproper and the welt, as well as to regulate the machine to accomodate different thicknesses of hats to be operated upon and means to maintain the hat in proper alignment when the welt is being sewn. I I

Having described my invention, what I claim as new is:

1. In a hat welt sewing machineprovided with a support, a plate swingingly supported thereon and provided at one end with a pair of clearance holes and a threaded holeintermediate the said clearance holes, a hat welt regulating and guide member, a pair of screws extending throu h the said clearance holes and supporting t e guide member, and a screw in the threaded hole in the plate adapted to maintain-the guide member in an adjusted position when either of the guide supporting screws are loosened.
