IMPROVEMENT IN GIN-SAW-FILING MACHINES.

Speciticatibn forming part of Letters Patent N0- 150,809 dated May 12, 1874; applicntion liled Manch 23, 1874.

T0 all whom it may concern Be it l;nown tlmt I, LEWIS MONROE ASBILL, 0f Ridge, in tl1e county 0f Edgefield and Stute 0f Souh Carolina, hzwe invented a new und Ixnproved Gin-Smv-Filing Machine; und I d0 hereby dec12ue that tl1e following is a full, dem, 2md exact deseription 0f t-l1e sinne, reference being had t0 the acconnmnying dmw ing forming a paa*t 0f t-l1is specification, 111 whioh 1 Figu1 1 is a side elevatioi1, und Fig. 2 a plan view.

'lhe invention relates generally to machin0s tl1at are usedt-o facilitate the filing 0f gin-szuv teeth, and to supersedethe old meaus 0f perfoiuning tl1e W0rk by band, but 11101e part-icu- ]arly t0 the improved machiue 011 which a patent was granted to me 011 the 3lst 0f Decen1ber, 1872. T110 iinprovements consist 'in means forgiviug a variable adjustmenj: t0 the file-stroke, while the forw2ud end or poiut 0f tl1e file is 11015 changed in osition. V

A represents the erank driving-wheel that operates a pinion, B hzwing the crank-arm Z). T0 13116 wrist; 011 the' end of this arm a1e attaehed pitmen O, Which vibrate a leve1y D, and, through a eonnecting-strap, E, move the file-holder F in its guide-tube G. I n1ake the levers D D with the end d perfomted ab sove1al points, and -on an ar0curve, so tlm'n phe strap E may be adjusted 1n01e nearly to 61 moxe remote fr0n1 the fulerum d, tlu\s regulatin g the throw 0f the file-holder, while the front of the file is thus alw-ays correspondingly adjnsted, so as t0 be carried t0 the szune forward p0iut: m: every IGCiPIOO2IOII. 1;he g11id-tube G an oblique slot g, in which the shzu1k 0f the file-holder piu f slides. B y this consruclsion I czmse ehe file t0 turn slight-ly 01' roll in its socket-guide G as it moves, und 130 give t0 'the gin-tooth a briar-point. The object 0f producing this peeuliar point is to czu1se the teeth t0 enter the cotton more rezulily and thus cut 01 break the ber less, us

' well zus allow io 110 be 1nore easily cleaned.

Having thus described my invention, what I claim is+- The lever D, curved ab t-he end d, a11d 112W- 1'ng severa-l perfomtions, as deseribed, t0 allow ehe throw 0f file-holder t0 be regulated witl1 01111 changing the farthest p0int to whieh the end 0f the file will go at auch forward stroke.
