Y 1 l As a ,means for driving the machine a ydriviingpulley 27/is secured to the 112,-this pulley: preferably beingsY groovedY iny a man-` Y ner 'commonto'structuresof'this class and f Y ing Wheel Von lthe V'sewing .machine and in; a e

mannernthat 'willbe readily understood, The pulley'r 27 Jis loose on'thef shaft l2 lbut isy ,com vnected therewith, as by means of a clutch 29 struction and which may be supported as by a. bracket from the rear of the table 10, and as shown in Figure 5 'of the drawings. This 'clutch comprises a clutch member 31 actuated 7Vas by means of a clutch arm 32 se'- qu'red to a clutch operating shaft 33 rotatta'bly mounted in a frame constituting the legs or table support at this end of the machine. The shaft 3.3 is rotated to effect engagement of the clutch `member as bymeans of a cord 34 or -similar flexible connection extending from a treadle 35 pivotally supported on a rod 36 secured to and extending between the legs or supporting frames at opposite'ends of the machine. The cord 34 passes over a sheave 37 and to one arm 38 of a lever secured vtoand projecting from the shaft 33, and as shown in Figures 5, 6 and 7 of the drawings. The other arm of said lever has a spring 39 secured at one end thereto, the opposite end of said spring being secured to one of the legs 11, said spring holding the members of the clutch mechanism disengaged, and the treadle 35 being employed to engage the clutch members for'the `purpose of starting operation of the sewing machine. Y v v f The presser foot of the sewing machine is automatically actuated by the "mechanism just described for starting andst-opping the machine, this presser foot actuating mechanism comprising a presser foot actuating lever 40 having 'one arm underlying the end oa presser foot actuating rod 41 connected 'with the 'presser foot in any suitable manner to cause said foot to be loweredin-the operationof the mechanismr to start the `machine kkandto ybe raised in the operation of stopping machine. lIn`V the arrangement herein shown the other arm of said lever is connected by a rod 42 with the machine starting arm 38 hereinbefore mentioned so that when ysaid. arm 38 is actuated to start the machine the presser foot will beautomatically lowered and vice The mechanism forcutting and severing measured lengths ofk material, as hereinbefore referred to, comprises a frame adjustablymounted to produce kmopsofdiierent lengths, said fframe movably supporting. a cutter for operation thereof. rSaid frame com rises'an end 43 located atV the back of the mac ine, a top 44,-sides 45, and tie bars 46. The end 43 has a shoulder 47 extending across Yit from edgeto edge, saidshoulder being seated upon a bar comprising ay guide X48 secured to lugs projecting from a depending iiange at.r the back of the table 10, .and as Yshown in Figures 3 and 4 ofthe drawings.

A gib 49 is-secured to the front side'of the bracket orend 43p'andprojects downwardly below the shoulder k47. This gib has a screw Vthreaded stud engaged by the screw threaded hub of a clamp wheel 50 by means of which the'gib'is clamped against the guide 48 to holdA` the-cutter frame in any position to which it kmay have been moved. A support 51 in the form of a lip projecting downward ly from the front of the top 44 rests upon a ledge 52 projecting from the back surface of a tiange 53 extending downwardly from the top 10 at the front of the machine. The tie bars 46 project through lugs 54 extending from vthe lower edges of the sides 45 and also through lugs 55 projecting from the opposite edges vof the frame end 43, nuts upon the lends ofthe bars serving as a means for rigidly securi the4 frame parts together. The frame end`4 is supported bythe shaft 12 that extends throughholesy suitably formed in branches 56 at the lower edgey of the frame thereby enabling the cutter frame to be adjustably positioned for the purpose of cutting mopsof different lengths. A cutter support 57 in the form of a barframe is loosely su ported on the shaft 12 for adjaustable sli ing movement thereon, the bearings for said support comprising ears 58 through which the shaft extends. A cutter driving pulley 59 -issplined to the shaft 12 between the ears 58 and a belt 60 extends from said pulley to a'pulley 61 secured to the .shaft of a cutter 62y rotatabl mounted in bearings 63 in branches extends: ing fromr the front end of the supporty 57. The support 57 normally rests so that the upper edge of the cutter 62 is below the table 44, this position'of rest being determined by a cutter positioning screwv 64 rotatably secured at its upper end in a lug projectingy from the under side of the top 44,'and as shown in Figure 4 ofthe drawings. This screw rotatablyV engages a supporting loop k65 having an o emng into'which a lug at the front end o onefof the sides'of the support 51 extends, this lug being forked to extendon opposite sides of the screw 64, and as shown in Figures 3 and 4 ofthe drawings. 'Y In order to minimize the amount of power required to swin the sup ort 57 on its ivot at the rear en thereo va counterba ance weight' 66 is suspended fromone end of a cord 67, the opposite end ofsaid cord being secured to the support 57after passing overy sheaves y mounted in `lugs `projecting from the under side of the top 44,`and as shown in Figure 4.0i the drawings. v

When the cutter 62 is raised to cut armass of mo material in a manner to be hereinafter escribed, it is projected through a slot 68 in the top 44 and in order to avoid accident to a person when the cutter is thus pro,- j ected, afguard is automatically lowered over `the slot 68 to enclosethe vedge of thelcutter vprojecting through said slot. comprises a Vhood 69 supported to rto This guard a slight extent between the side parts of a hood supporting frame 70 pivotally mounted at its rearf end .on aylug 71k extending from end, these branches loosely receiving the shaft :Lemans the 4upper yedge yof the bracketor frame `end,

43 preferably'at one side thereof. v A hood actuating rod 72is pivotally con nected at itsupper end toa cross piece eX-. 5 tending between the side parts of the supportf:

i ing frame 70, the lower end Vof said rod being l securedto an ear on the side of a `cylinder 73.

This cylinder contains a-piston of any ordinary form havinga piston rod 7 4 pivotallyV 10 [attachedv'tooneof the side parts of the support 57. Av lexiblehosezor tube 75 extends from the lower end of the cylinder 73 into the base'of a cylinder-76 supported, as on aV floor, this cylinder V7 6 having a piston of any ordinary constructionl therein from which a piston rod 77 extends, the uppery end of said rod being `pivotally attached to vone end of a yraised positions. n i

When the pedal 79 ispressed down, as by ythe foot ofthe operator of the machine, inward movement of the piston in thel cylinder 76 will, through the tube 75, create pressure f inthe bottom ofthe oylinde1fi7 3 which pres-` sure will act in .opposite directionsLagainst:

thek bottom ofthe c linder 73 and piston therein.. The strengt A"of the springl 82 .is

such that resistance to downward movement` of the cylinder 73 is lessfthan the resistance to upward movement of the support 57, wherefore" .the pressure in thek cylinder7 3 Vwill cause the latter andthe frame 7 0 to be moved 'downwardly tocause the'hood ,69` to cover the cutter 62. When the hood "comes in Contact :with the upper surface of thetop ofthe cylinder 73 is prevented whereby the pressure in the cylinder will now act to force y.the piston outwardly therebymoving the support-57 and the cutterlthereon upwardly, the latter through the slot 68,' thereby ysevering the "mass ofk threads projected across said slot. AUpon release ofthe p'edal7 9 al reverse action of the parts will takevplac`e,thus.re-

storing the cutter and-hood to their normal positions, ythe cutter being moved. vdownwardly from within the slot before thejhood moves upwardly to uncover the slot.V l

The tape 24 is nowy wrapped about `the length 22 of materialxand the whole is slidable under the needle ofthe sewing machine and maybe manipulated to sew the parts to'- gether in such manner as may be desired.

613'k It will be noted that an opening 80 is made in the table l() and that the` top 44: of the cutter `frame projects through this opening substantially closing-itV except as to one'sider thereof.
