' iv and has forits object to provide, in, a;man-

Be it known that I, SAMMY C. BRAY, citizen of the United fitates, residing at Springfield, in the county; of Greene and State of M ssouri, have invented certain new "and useful Improvements in SewingeMachine Needle Guards, of which the following s a spec fication,

-This invention relates to needle; guards for usein connection, with sewing machines,

ner as hereinafter set forth, a guard of such class for connection to the presserf foot of the'machinje and further to'extend into the path of'and enclose the lower terminal por tion of the needle in a manner to prevent the fingers of .the operator from being injured;

by or to come in contact with the needle during-the operatlon thereof.

-Further objects of the invention are to a'needle-guardforthe purpose set forth which is simple in its construction and arrangement, strong, durable, readily installed I with respectto'the presser footof the ma struction, combination and arrangement of parts as hereinafter more specifically 'de scribed, andillustrated in the accompanying drawings, wherein is shown an embodiment ofthe invention, but it; is to be understood; that changes, variations and modifications; 1 can be resorted to which fall within the,

scope of the claims hereunto appended. v In the drawings wherein like reference characters denote corresponding, parts throughout the several views f u Figure 1 isa side elevation of a pressure foot, needle barand needle, showing the adaptation therewithof a guard lIl accordance with this invention.

'Figure 2 is a sid elevation of the guard when extended. and further illustrating in V dotted 'lines the I guard when -.contracted to permit of the removal ofthe needle when ode-H sired. a I" I r p Figure 3 is atop plan view of the: guard.

Figure 4'isan invertedplan view.

Figure 5 is a section onfline 55 -Fig'-' Figure6 is a section on line 66 Figure 3. Referring to the drawings'indetail 1 denotes a presser foot, carried on the lower end of a presser foot bar 2. Aneedle bar is in-K dicatedfatfi and which has, detachably secured to itslower endthe needle 4'. The. forego ngjelements are of known construe tion and'are illustrated so that the position of the guard can be shownin operative re lati'on with respect to the-needle 4.,

A needlejguard, in accordance with this inventionco nprises a carrier constructed of: sheet metal and consisting of a bodyrpo'rtion 5 formed at its inner side With a vertically disposed tubularmember G-for a function. to be presently referred to." Depending from} the bottom ofthe bodyportion 5 and flush with the outer side edge thereof isfa suspenjsion member .of substantial ,width 7 and,

formed of a'verti'cally disposed upper porf tion 7 and a laterally extending curved lowerjf portion 8 V which terminates in an upstanding vertically disposed tubular member 1 9 having the rear side thereof cut away toform an opening I 10 hicheXt-ends"from the lower end of: the member 9 and terminates at'a point-removed from the upper end thereofg The member 9 isformed with an inwardly sideedge of the vertical portion 7 of the suspensionmember an arm 12,exteir ding in an opposite direction with respect to the freefend, isvprovidedcwith inwardly diected'flange 13. The arm 12 is furthermore formed with an opening 14. The arm.

curved lower portion 8 of the suspension member .or arm and tl1e*sa1d;'ar m '12, at its 12 isv arranged against; the outer-side or 7 rather front side of the presser foot 1 and the tubular member 6 is arranged at the rear side of the presserj foot 1. Extending through the opening ltis a clamping screw 15, which in'connection with theftubiilar,

member .6 'j and the arm 12 detachably secures 1 i the carrier to'the presser, foot 1 in a manner as shown in Figure ,1 so that thetubular member 9 will be positioned within the path of the needle 4;; The tubular 'member 9 forms a stationary section of the guard element of the device and such guard element will be presently referred to.

tubular member 9, is of the telescopic type so that when the sections thereof a're nested,

, azneedle can be removed and a new one sube stituted.v

. The guard element comprises an upper tu- The guard element, which includes the bular sectioniltihaving an inwardly extending annular flange 17 at its lower end, an intermediate tubular section 18 whichextends through the flangel'i and has its upper end provided with an outwardly extending annular flange 19 and its lower end with an.

inwardly extending annular flange 19. The flanges 19 and 19 when the guard element is extended abut respectively against theflanges 17 and 9 to prevent the separation ofthe=sections of the guard element. The=fiange 9 is formed at and extends outwardly from the upper ofthe tubular members 9 which is termed'the lower section of the: guard-element and which extends into the intermediate section 18; The upper section 161=fricti0nally engages withthe peripheryof the intermediatesection"18- sothat when the upper section 16 is lowered in a manner ashereinafter referred to,- the upper sectlon 16 will carry theintermediate section {18' therewith and both sections will be arrested by-the curved lower-portion 8 of the suspension member or arm. The -tele. scopic position ofthe sectional guard element, when in nested position, is shown in dotted lines 1nv Figure 2. The guard element is .ofa different color from that ofth'e needle to make the latter more discernible.

A shiftable spring controlled suspension device co-acts" with the upper section 16 of the guard element, to maintain the latter in extended position and when the suspensionv devlce, is shifted manually against the action of its controlling spring, the sections of the guard element can be shifted to nested position whereby the top edge of the upper sec: tion .16 of the guard element will be positionedbelow'the point of the needle to per lIlitlOf the latter being removed. Thespring controlled suspension device consists of a collar'20 carried on the lower end of a spring. controlled suspension rod. 21 which extends up through the tubular member 6 and has mounted on its upper portion a coil control-.

ling spring 22, which is interposed between the top edge ofithe tubular. member 6 and a head. 23provided' at the upper end of the rod 21. The collar 20. is connected to the lower .end of therod 21, by an angularly extending bar 24 which has its outer end fixed to the outer periphery of the upper section 16 of the guard element. The bar 24 extends through the collar 20 and the lower end of the rod 21. The controlling spring 22 normally maintains the collar 20 in abutting engagement with the lower end of the tubular member 6, under such conditions mainta ning the sections 16 and 18 of the guard element in the position as shown in Figures 1 and 5. If it be desired to nest the sections of the guard element, relatively to each other, the rod 2lis .shifted to the dotted line position shown in Figure 2 and against the action of its controlling spring 22. hen

fall within the scope of the inventionasclaimed.
