Specification of Letters Patent.

Patented June 15, 1915.

' To all whom it may concern:

Be it known that I, HENRY FUI-IRY, a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new :and useful Improvements in Devices for Cutting Fabrics, of which the following is a specification.

My invention relates to improvements in devices for cutting fabrics, and it pertains more especially to that class of machines which are used for cutting trimmings 0r foundations used in the manufacture of hats.

My invention is explained by reference to the accompanying drawings in which,

Figure 1 is a side View part in vertical section drawn on line 00, w of Fig. 2. Fig. 2 is a top view of the device shown in Fig. 1. Fig. 3 is an end view, part in vertical section, as indicated in dotted lines y, y of Fig.

. rics, I employ two circular . cutting blades 1 and 2. The cutting blade 1 is revolubly supported from the shaft 3, by and between the arms 4, 4, and said armsare rigidly connected with the vertical movable bar 5, and

said bar 5 is slidably supported from the arm 6 in the head 7. Said bar 5 is provided with a transverse pin 8 and an eccentric cam 9. The eccentric cam 9 is pivotally supported from the upper end of the bar 5 by the bolt 10. Thus it will be obvious that when the eccentric cam 9 is in the position shown in Figs. 1 and 3, the bar 5 is drawn upward, whereby the cutting blade 1 is separated from and raised at quite a distance above the cutting blade 2, as shown in Fig. 1. When, however, the eccentric cam 9 is thrown in the reversed position, shown in Fig. 4, the cutting blade 1 is forced downwardly by the recoil of the spiral springs 11. The spiral springs 11 are interposed between the upper end of the head 7 and the pin 8, and said springs are adapted by their recoil to force said cutting blade 1 down with a quick positive movement, whereby the cutting edges of the two opposing blades 1 and'2 are caused to slightly over-lap each other, as shown in Fig. 5. When a fabric is brought between said blades 1 and 2, it is severed by the action of said blades. The blade 2 is rigidly aflixed to the shaft 12 and is adapted to revolve with it, while the blade 1 is revolved solely by the action of the fabric passin beneath it as it is being severed. Supported upon the respective sides of the blade 1 are two feed rollers 13 and 14, which are adapted to contact with the opposing feed rollers 15 and 16, which are rigidly secured to and carried by the shaft 12. The surfaces of said feed rolls are preferably slightly serrated or roughened, as shown in Fig. 1, whereb the fabric is more readily drawn forward between them as they are revolved by the action of the shaft 12.

- 17 is a band wheel which is rigidly affixed to the shaft 12, from which motion is communicated through said shaft to the cutting blade 2. It will be understood that the band wheel 17 may be driven either manually or by any other power iii the ordinary manner.

Preparatory to inserting the fabric to be out, the eccentric cam 9 is moved from the position shown in Fig. 4 to that shown in Fig. 3, whereby the cutting blade 1 and feed rolls 13 and 14 are raised quite a distance from the cutting blade 2 and feed rolls 15 and 16, whereby the fabric may be readily inserted between said rollers. When trimming a hat or cutting the crown it can be inserted between the rollers, as indicated by dotted lines in Fig. 1. When this is done the eccentric cam 9 is brought to the position shown in Fig. 4, whereby the cutting blade 1 and feed rolls 13 and 14 are brought to the position indicated in Fig. 5. When this is done the shaft 12 is revolved, whereby the fabric is fed forward by the feed rolls 15 and 16 cooperating with the feed rolls 13 and 14, whereby the fabric is severed by the cooperation of the cutting blades 1 and 2. It will be understood that by thus operating the cutting blades and feed rollers by the revoluble movement of the shaft 12 the operator is enabled to place a hat or any other fabric between such cutting blades, while owing to the fact that the upper blade 1 and feed rolls 13 and 14 are revolved solely by the friction of the fabric as it passes between said cutting blades, it becomes unnecessary to connect the upper enabled to move the hat or other fabric to be acted upon with the greatest freedom bej tween such cutting blades and feed rolls.

18 is the bed plate of the machine, which is preferably made narrow at its front end or at the end adjacent to the cutting blades, whereby the hat or other fabric may be readily revolved around said bed plate as it is passed between said cutting blades. 7

19 is .a 'handle,wl 1ich1is rigidly connected with the eccentric cam 9, whereby such cam is readily moved by the operator;

Attention is called to .the fact that the arm 6 is unusually long whereby a large space is providedupon the .table or platform 18 for .the reception of the hat or other fabric which is being operated upon by .the cutting blades, while the vertical member of said arm -6, shown at the right in Fig. 1, is at a great distance from said cutting blades. This is very important as it often becomes necessary torevolve the hat upon said supporting platform 18 as said cutting blades .are operated.

7 Having thus described my invention, what I claim as new and desire to secure by Letters Patent, rs-

1. In a device of the described class, the

combination of two circular cutting blades,

' adriven shaft supporting one ofsaid cutting blades, a stationary shaft supporting the other cutting blade, a vertically moving bar for supporting said last named shaft, said last named blade being adapted to be revolved by the movement of the fabric which is being cut by said blades, means for revolving said revoluble shaft, and means for raising and lowering said vertically moving bar.

2. In a device of the described class, the combination of two circular cutting blades, a driven shaft supporting one of said cutting blades, a stationary shaft supporting the other cutting blade, a vertically moving bar for supporting said last named shaft,

said last named blade being adapted to be p revolved by the movement of the fabric which is being cut by said blades, a band wheel rigidly connected to one end of said revoluble shaft, and means for raising and lowering said vertically moving bar.

.3. In a device of the described class, the combination of two circular cutting blades, a driven shaft supporting one of said cutting blades, a stationary shaft supporting the other cutting blade, a vertically moving bar for supporting said last named shaft, said last named blade being adapted to be revolved by the movement of the fabric which is being out, two feed rollers one supported upon the respective sides of each of said cutting blades, means for revolving said revoluble shaft, means for raising and lowering said vertically moving bar, a long arm adapted to support one of said cutting blades above and at a distance from the opposite edge of the platform of the machine.

4. In a device of the described class, the combination of two circular cutting blades, a driven shaft sup )orting one of said cutting blades, a shalt supporting the other cutting blade, a vertically moving bar for supporting said shaft, said last named blade being adapted to be revolved by the movement of the fabric which is being out, two feed rollers one supported upon the respective sides of each of said cutting blades, means for revolving said revoluble shaft, means for raising and lowering said vertically moving bar, and a pair of springs connected with said vertically moving bar and adapted to hold the upper feed rolls and cutting blade in yielding contact with the lower feed rolls and cutting blade, a long arm adapted to support one of said cutting blades above and at a distance from the opposite edge of the platform of the machine, all substantially as and for the purpose specified.

In testimony whereof I affix my signature in the presence of two witnesses.

HENRY FUHRY.
