ED" STATES LOUIS MEYLACH, or BROOKLYN, NEW YORK.

Application filed December 8, 1926. Serial No. 158,396.

This inventionrelates to edge slittingmachines and has for its object to provide a machine of theclass specified, of simple construction,- easy of manipulation and swift andiaccurate in operation.

To these ends and others which will appear later herein my improvements comprise'features illustrated their preferred embodiment in the drawings accompanying this specification, wherein:

Figure 1 is an and elevation of my improvedmachine. Fig. 2is a rear elevation corresponding therewith. Fig. 3 is plan of the major portion of what is shown above theta ble top'in Figs. 1 and 2. Fig. 4 is an elevation partly in section on line 4+4 of Fig.3 and Fig. 5 is a similar section on line 5"-5 of Fig. 3. Fig: 6 is a fragmentary sec tion. showing parts adjacent to and overlapping the left portionof Fig. 5. The scale of Figs. 1 and2; is thesame, and the scale of the other figuresis about four times that of-xFiguresL and 2.-

While my; improvements are adapted for employment in a wide field, they are herein illustrated asiparticularly designed for slitting the edges of felt hats, such for instance as simply indicated at 3 in Fig. 5. I

Directing attention now more particularly to the drawings my improvements may be conveniently mounted on o posite sides of a horizontal plate 2, preferably supported on short legs as 6, and which legs may rest on a bench as 7 to raise the device a suitable distance from the floor for convenient operation.

The cutting or slitting tool comprises a rotary circular cutting disc 8 having its edge sharpened. Said disc is removably-secured to the upper end of vertical spindle 9 rotatably mounted in bearings in block 10 depending from table or plate 2. To the lower end of spindle 9 is fixed pulley 11. Spindle 9 comprises upper and lower portions, the lower portion being constrained against vertical movement and the upper portion being vertically adjustable so that cutter may be set at varying distances from the top face of table 2 to accommodate various thicknesses of brims 3. Rotary motion is transmitted from the lower to the upper portion of said spindle through the flatted spindle elements shown at 12. For adjusting the upper portion of said spindle vertically, grooved collar 13 is fixed to said spindle portion and yoked lever 14. pivoted at 15 in an upwardly accessibility. and terminates ear 1? through 'WlllCl'l lS threaded adjusting screw l8,whosc of feed rolls 20,21 are ear of block lO'hasopposite pins as 16in engagement with the rim groove in said collar. The upper'end of lever 14 projects to above table 2 into convenient left hand end, Fig. in bracket 19, table2; i

For rotating the hat brim 3 and presenting its edge to the action of cutter 8 a pair provided. These are arranged one above the other at the leftof cutter 8, Fig; 3 and their parallel axes are angular-1y disposed, the inreaching ends of the rolls hat. Lower roll 21 has its upper edgeapproximately-in the plane of the table top and. upper roll '20 is spring: urgedttoward 6, is revolubly mounted reaching rearwardly from pointing toward the centerof'thesaid lowerroll, so=that said rolls'ar'eeflicient for gripping. and feeding forwardly toward the le'ft, a hat brim fed therebetweenu The shaft 22 of roll. 21- has bearings projecting downwardly from table 2: and upper-roll shaft 23 has its bearing in vertically slidable block 24 in housing 25; urged downwardly by adjustable spring 26. Shafts 22, 23 are geared together by gears 27 28 respectively and bevel gear 29 fixed to shaft 22 meshes with and is driven by bevel gear 30. Said gear 30 is fixed to worm gear 31 and they together turn on stud 82 depending from table 2.

Adjacent worm gear 31 is bracket 33, fixed to the lower face of table 2 and therein is revolubly mounted shaft 34 to which is fixed worm 35 engaging and driving said worm gear. Also to shaft 34 is fixed pulley 36. Pulleys l1 and 36 are driven by the usual belts from. suitable pulleys on shaft 37 of motor 38.

For holding hat brim 3 snugly against table 2 as the brim is fed forwardly to the left, Fig. 3, in engagement with cutter 8, presser foot 39 is employed. Said presser foot is preferably a portion of a flat annular ring conforming to and overlying the periphery of the cutter, thereby performing the double function of a cutter guard and presser foot. Said presser foot is fixed to the lower end of vertical stem/0 slidably mounted in bracket 41 upstanding from table 2 and adjustable thereon to accommodate different diameters of cutters.

Fixed tosaid stem is block 42 which engages the face of bracket 41 to prevent rotation of stem 40 while permitting vertical movement thereof. Between the upper face of block 42 and adjusting screw 43 is spring 44 for urging presser foot 39 downwardly.

For limiting the downwardmoveinent of presser foot 39 screw 45 is threaded in block 42 and abuts against lower ear 46 of bracket For guiding the hat body 3 so thatthe edge of brim 3 will be properly presented to cutter 8 outside roll 47 is mounted for free rotation in the right hand end of arin' 48,

Fig; 5, and is adjustable therein, to accom- Inodate different widths of brim. For coop v eration with roll47, inside roll 49 is pivotally bymeans of pull chain 53, one end of which i is fixed to said block and the other end to foot treadle 54, Fig. 1, the chain passing over pulley 55 fixed to the under part of table 2.

I claim:

v 1; In amachine of the characterispecified the combination of a revoluble cutter, means for rotating said cutter, means for adjusting said cutter axially,a roll for spacing for depth of cut an article to be slitted, rela tively to said cutterymeans for adjusting said roll relatively to said cutter, a second roll,springurged and slidablymounted, for

maintaining said article in operative engagement with theifirst mentioned @011, means for withdrawing said second roll from coaction with said first mentioned roll, means for feeding an article to be slitted to engage- I ment with said cutter compris ng a pair of feed rolls, means for rotating said rolls,

spring means for urging one of said rolls toward the other thereof and means. for adjusting said spring means. 7 i j 2. In a machine of the character specified, the combination of a revoluble cutter,means for rotating said cutter, means for adjusting saidcutteraxially, a roll for spacinglfor depth of cut an article to beslitted, relatively to said cutter, means for adjusting said roll relatively to said cutter,a second roll, spring urged and slidahly mounted, for maintairb ing said article in operative engagement with the first mentioned; roll, means for feeding an article to be slitted to engagement with said cutter comprising a pair of feed rolls, means for rotating said rolls, springmeans for urging one of said rolls toward the other thereof, a presser 'lootyspring urged,for

holding down an'article to be slitted, means a for adjusting said spring means, said presser foot being curved for overlying a portion of i the cutting edgeiofzsaid cutter and adjustable means for limiting the downward move-i ment of said presser foot.

In witness whereof, I hereby afiix my si'gnature this 6th dayof December, 1926. -f
