TTOHWE Y pinion 32, in turn, meshes with a gear wheel 34 secured to ashaft 35 rotatably supported by the bracket 2O and by a bracket 36 secured to the machine head 10. The shaft V35 is provided, intermediate theV supporting brackets and 36, with an endless screw 37.

A rod 38, slidably and rotatably supported by the bracket 36 and by a bracket 39 secured to the head 10, carries a pair ofspring pressed jaws 40 which are held in position upon the rod 38 by sleeves41 and 42 fixed thereto adjacent one end thereof. The inner ends of the jaws 40 are provided with recesses shaped to conform to the endless screw 37 and provided with threads to engage the Y threads thereof, wherebythey jointly form a travelling nut, constituting a follower. As

theendless screw 37 is rotated, the'follower,

Y initsvsupporting brackets 36 and 39.

vformed of the inner ends of the jaws 40, will travel along vthe same, thereby causing a longitudinal movement of the rod 38 with- An actuating member 43 is adj ustably supported by the sleeve 4l, and is so positioned that, when the rod 38 has moved a predetermined dist-ance, it will engage the free'end .of an arm V44, operatively connected to the pulley 17, and actuate the arm, 44 to move the pulley 17 out of engagement with the clutch member 19,. in order to disconnect the same from the driving shaft 16 of the electric motor 15.

A supporting memberV 45, fixed to the rod 38,- has removably secured thereto a guideplate, which servesv to support the hat-brim andto feed the same to the needle 12, transversely to the normal line of feed. As shown in Figs..1 to 5 inclusive, the guide-'plate consists of two sections 46 and 47, having their outer ends pivotally connected toy one another, as by a screw 48 engaging a block 49, AVand havingtheir inner ends adjustably connected to one another by means of bolts 50, 50 carried by the sections 46 and 47 and engaging aslotted, arc-shaped link 51. The sections 46 47 of the guide-plate vare provided at theirV outer edges with upwardlyextending walls 52 provided, throughout a 'portion' of their length, with inwardy-extending portions 53. A finger-piece 54, carried by the block 49 `and by a bracket 55 secured tothe rod 38, is provided for adjusting the rod 38 relatively to the machine head 10 in order to properly position the guide-, plate 46, 47 with respect to the needle 12 at the beginning of the stitching operation.

The guide- plate 46, 47 above described, is Aadapted for use in connection with the stitching of hat-brirns of the tubular type shown in Fig. 7. For stitching hat-brims of the flat, annular type, shown in Fig. 8, an arcshaped guide-plate 56 is employed having upwardly-extending walls 57 at its outer edges, as shown in Fig. 6.r

When either` one of theguide-plates is in use, its inner end rests upon the bed plate of the machine head 10 in front of the needle 12, thus insuring that the hat-brim to be stitched will beproperly presented to the needle 12, and the side walls of the guide plates prevent lateral shifting of the hatbrim. When the guide plate 46, 47 is used the sections thereof are so adjusted relatively to one another that the distance between the inner ends of the walls 52, 52wi1l correspond to the width of the hat-brim to be stitched.

The operation of the machine is as follows :V-V j i The guide plate 46, 47 or the guide plate 56, is affixed to the supporting member 45, depending on whether the hat-brim to be stitched is of the tubular,r or fiat, annular type, and the rod 38 is moved to the left, as seen in Fig. 1, in order to position the guideplate in advance of the needle l2. lVhen moving the rod 38 to thus adjust the guide jaws 40 will be opened to disengage them from the endless screw 37, by pressing upon the free outer ends thereof When the guide plate is thus adjusted the hat-brim to be stitched is placed in position upon the guideplate and upon the bed plate of rthe machine head 10. The arm 44 is then moved to cause the pulleyr17 toengage the clutch member 19 on the motor shaft 16, whereupon rotation of the shaft 13 will be effected. The rotation of the shaft 13 will operate the needle bar 11, carrying the needle 12, in the usual manner, and will also cause the rotation of the endless screw 37 on the shaft 35 by means of the gearing` above described. As

the endless screw 37 rotates it will cause the guide plate 46, 47,v or'56, as the case may be, to travel at a uniform rate from the left to the'right, as seen in Fig. 1 in'a direction transverse to the normal line of feed of the machine Yand lat a slower'sp'eed than thatof the normal feed, thus 'causing the stitching to be produced upon the ma- Y terial in a spiral form. i

At the completion' of the stitching Voperation the actuating member 43 will engage the free end ofthe arm 44 and move the same to throw the pulley 17 out of engage-V ment with the clutch member 19, whereupon the operation of the machine is stopped.

The distance between the adjacent rows of stitching on the hat-brim may be varied by varying therate ofrotation of the endless screw 37, which controls the transverse movement of the guide plate.r The rate of.`

rotation of the endless screw 37 may be altered by varying the proportion of certain of the gears and pinons, for example, by removing the gear wheel 27 and pinion 30,

plate, itis of course understood that the or either thereof, and substitutingin place.

thereof a gear wheel and a pinion having a greater or a less'number of teeth. The thus substituted gear wheel and pinion may be readily adjusted to mesh with one another and with the remainder of the train of gearing by varying the positions of the adjustably mounted arms 22 and 24 relatively to one another and to the support 21, and by adjustably disposed upon said slotted mem-y varying the position of one or both of the studs 26 and 33, upon which the gear wheels and pinions are mounted, within the slots 23 and 2.5 of the arms 22 and 24.

Having thus described my said invention what I claim and desire to secure by Letters Patent is:

l. The combination of a sewing machine with a support to receive theV article to be stitched and a'rotatable member operatively connected to said support for moving the same transversely to the normal line of feed ci the machine, a driven gear on said rotatable member, a driving gear for transmitting movement to said driven gear, an intermediate gear between said driving gear and said driven gear, a supporting bracket for said intermediate gear, a pair of slotted members carried by said bracket and a stud` adjustably secured upon said slotted members, substantially as specified.

2. The combination of a sewing machine with a support to receive the article to bc stitched and a screw-threaded member operatively connected to said support for moving the same transversely to the normal line of ieed or" the machine, a driven gear on said screw-threaded member, a driving gear for transmitting movement to said driven gear, a supporting` bracket, a slotted member pivotally mounted upon said supporting bracket, a second slotted member associated with said first-named slotted member, a stud bers, and an intermediate gear mounted on said stud for transmitting movement from said driving gear to the gear on said screwtihieaded member, substantially as speci- 3. The combination of a sewing machine with a support to receive the article to be stitched and a screw-threaded member operatively connected to said support for moving the same transversely to the normal line of feed of the machine, a driven gear on said screw-threaded member, a driving gear for transmitting movement to said driven gear, a supporting bracket, a slotted member pivotally mounted upon said supporting bracket, a second slotted member associated with said first-named slotted member, a studV a plurality of sections adjustablyconnected to one another at their outer ends and having means adjacent their inner ends to hold them to their adjusted positions, and means tor moving said platetransversely to the normal line of feed of the machine, substantially as specilied;
