thread-tensions, as 168, and thread-checks,`

as 169. For giving rotary movements 'to the plate 167 corresponding to the rotary movements of the cylinder 11 and hollow standard 29, the horizontal shaft 160 is provided with a. worm gear 170 which meshes with a gear 171 carried by the upright shaft 172 mounted at its lower end in a bearing formed in the bracket arm at its upper end in a bearing formed in the bracket 64, said shaft carrying at its upper end a sprocket wheel 173 corresponding in diameter to the sprocket wheel 166, a belt 174 acting to transmit motion from one to the other of said sprocket wheels.

175 represents the cord or tape supply bracket'secured by a screw 176 upon the Lipper end of the cylinder 11, and in said bracket are secured, by suitable screws, holders, as 179, upon which are mounted braid or tape supply spools, as 181. To guide the braid or tapefrom the supply spools to the action of the needle or needles, suitable grooves 185 and 186 of unlike proportions are formed in the cylinder 11 to accommodate different widths of braid or trimming. 1n order that the braid or tape.

mav be )rotected from becoming soiled as it passes along that portion of the cylinder 11 embraced by its bearings, the grooves 185 and 186 are connected attheir upper ends with tubular openings 187 and 188,

- (see Fig. 14) of thel braid-guide nipple'- 132,

when it is passed through the opening 192v formed 1n said standard, `down through the 'needle opening 193 andout undertheV tom ofi the nipple132in the directionpf..

'the feed, which is indicated by the arrow,

causingt-he needle to enter andemergefronn the so-termed y blind lor "hidden stitches. The -opening 190' directs the braid 'a5' through the needle vopening 193, in front of the needle and out under the bottom of the foot in the direction ofthe feed, thuskef'- fecting the ordinary through-and-'through or exposed stitches.

For securing the braid to t-he underside of the bod-y fabric either by exposed or hidden stitches, there is secured to the lower end of the hollow standard 29 a.. spool carrying bracket v194 provided iwith a braid supply spool 195, thebraid beingeled from .said spool up through the opening 196 in the hollow standard'29l and out through a suitable opening (not shown) formed in the bracket 30, from which point it is led through a'suitable braid-guide (not shown) formed in the needle-plate bracket 32, when it is passed through 'a suitable braid and needle opening (not shown) formed in the `needle-plate 33 and continued ina like di- 'rectionacr'oss the,l upper surface of -said 'fplatef'fr effecting the ordinary exposed lstitch. To cause the needle to .enter and. vemerge from the same side of the braid for the purpose of effecting hidden stitches,

-the operator loosens the screw` 200 and moves the toothed disk 157 out of engagement with the toothed disk 42, followed by giving tothe standard 29 and parts carried by it a half revolution, when the toothedv disk 157. is again secured in operative relationship withthe toothed disk 42, followed by re-setting the needle a half turn or in a position corresponding tothe adjustment of the toothed disk '42 and, consequently, the feeding foot, owing to the changed relationship of the braid guide 47 with respect to the Vfeed movements of the feeding foot 69,

.effects a travel o'f the braid over the needleplate 33 in a direction opposite to the travel of said braid beneath said needle-plate, or

"in a direction to cause the-braid to travel over the. needle-plate in jsup'erposed relationship with its travel beneath said plate.

The sectional views a and b, perspective c, plan d and underside view e of Fig. 13 illustrate the details in construction of the' needle-plate bracket 32 and needle-plate 33', for use in connection with two needles and two loop-takers, which differ from. the corresponding elements 32 and 33 of Fig.

@.theneedlefplate ,-33 'is `secured upon the bracketv 32 by screw 34, said' needle-plate` being provided with a depending portion 35 which enters an l'opening 36 formed in said needle-plate bracket, said depending portion' being provided with grooves, as 40, which .act as needle-,guards and assist in forming the needlefthrea'd loops.

' 47 represents a braid-guide which leads the braid from the opening196-n the standard 29 to the underside of the needleplate 33', where said guide 47 joins the guide50 formed in said needle-plate to direct said braid through the braid and needle opening 52 formed in the last mentioned plate, the loop-takers 48 being located so that their loop-seizing points will travel close to the curvilinear walls, as 56, or in 'position to seize their respective needle-thread loops asl the needles recede from the grooves 40. In the construction .of the 'stop-motion mechanism now to be described, the crank 24 carried by the main shaft 5 is detachably connected with the band or liandlwheel- Shaft 201 mounted `in a bushing 202 secured by screw 203 in the bracket arm 2, the inner endv of said band wheel 'shaft vcarrying a flangev 204 provided with an opening 205 with which a bolt 206 carried byl a cam flange 207 coacts, at the will of the operator, to determine the action and inaction of the main shaft relative to the shaft 201, as willnow be explained;

208 represents a bracket secured by screws, as 209,'to'the, inner rear wall of the standard 3, and on said bracket is pivoted, by

screw 210, a cam lever 211 'carrying at its upper end a roller (not show-n) carried by the vroller stud 212 which tracks a cam groove 213 fo-rmed in the cam 207 the .latter having movements on the main shaft in the direction of its length'in opposition to the resiliency of the spring 214 mounted on saidshaft and confined thereon by a pin 21,5 and Washer 216.

In the bracket 208 is mounted a stop-mo' ,tion releaseslide 217 provided with a forked lug 218 which enters a groove 219 formed vin the sliding collar -220 mounted on the crank shaft 138, dwhich shaft is made hollow from vits lowerend a 'distance sutlicient to`a c commodate a slide rod 221 mounted 1n said hollow portion and connected at its upper 'of said crank shaft.

end with the sliding. collar 220, said rod being held depressed by a spring 222 confined between the upper end of said slide rod and the end wall of the hollow portion The lower end of the slide rod 221 is pivotally connected, by a pin 223, with a rock-lever 224i carrying at its opposite end a roller 225 which enters a groove 226 formed in the hollow bushing 1117 carrying the Vcrank handle 146. rlhe stop-motion release slide 21T is provided at "its upper end with a lug 227 which, when 4 the machine is in operation, is located above he lug. 228 carried by the lever 211, thus ermitting the cam groovek 213 to continuously oscillate lthe lever 211 and allow the i --spring 214 to force the bolt 206 into operative relationship with the opening 205 formed in the flange 204, which adjustment is effected and maintained zby the operator forcing the crank handle 146 downward in opposition to theresiliency of the spring 222. When it is desire-d to bring the maJ -chine to rest, the operator allows the crank handle 1116 to be moved upward by the action of the spring 222, which causes the lug 227 carried by the release slide 217 to drop vin line with the travel of the lug 228 extending inward from the lowerend of the lever 211, and in the further rotation .of the main 'shaft 5 the action` of the camgroove 213 upon the lever 211 causes said lever to withdraw the bolt 206 from engagement with the opening 205, thus arresting the action of the main shaft 5 independent of the rotation of the shaft 201 and parts carried by the latter.

ln order that the main shaft 5 when it is brought to rest may always register the needle in the same posit-ion above the throatplate, thereis provided a verticallydnovablev spring-yielding plunger 2.35 seated in a suitable pocket -(not shown) formed in the bracket 208, the upper end of said -plunger' lbeingwedge-shaped, and when the bolt 206 is withdrawn from the opening'205, the end of said plunger rides the lperiphery of the VA flange 207 until it coacts with the `notch 240,

thus registering the main shaft 5 in its predetermined position. A

24.11 represents aflange secured to the cylinder 11 and seated in a bearing 24:2 formed in the lower ofthe bearings 12 in which said cylinder is journaled, 'said iiange acting to hold said cylinder againstmovement 1n the direction of. its length.
