SNIPPER FOR LEATHER OR FABRIC.

Application To all whom it may concern i Be it known that 1, WILLIAM G. Harm, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Snippers for Leather or Fabric, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specificati'on, in

Figure 1 is a perspective view of a snipping machine of my improved construction. Fig. .2 is adetail sectional view taken approximately on the line 2 -2 of Fig. 1. Fig. 3 is a detail section taken approximately on the line 33 of Fig. 1. Fig. 1 is a detail section taken approximately on the line4.

of Fig. 1. Fig. 5 is a detail section of the rotary blades or cutters forming a part of my improved machine. Fig. 6 is a fragmentary view of a section of fabric' or leather that has been snipped or cut in my improved machine.

My inventionrelates to a new and improved machine known as a snipper and particularly intended for use in shoe factories for snipping or cutting the curved edges of flexible sections of material utilized in the enufacture of shoes.

1n the formation of the vamps of shoes it is the usual practice to snip or cut the inwardly curved edges thereof in order that said edges may be readily turned under in orderto present a neat and finished appear ance when the shoe is completed, and where this snipping or cutting operation is performed by hand the cuts are generally irregular and of unequal depth; moreover, hand snipping or cutting involves considerable time'and labor.

I propose to produce a simple machine that can be operated with comparatively little power and which includes a rotary cutting member composed of a series of blades by means of which regular cuts can be very rapidly formed through a number of sections of fabric or leather.

The principal objects of my invention are, to provide a cutting member made up of a series of cutting disks and to arrange said cutting member so that it can be moved forward through the edges of a series of sections of material located on a work table, to

- provide a bra ing for the rotary cotter,

filed April 27, 1912. Serial No. 693,747.

which housing serves as a protection for the operator of the machine and to provide simple means including a clutch for throwing the machine into operation.

To the above purposes my invention consists in certainnovel features of construction and arrangement of parts hereinafter more fully described and claimed.

Referring by numerals to the accompany ing drawings, 1 designates a base, 2 a post or standard extending forward from said base and 3 a work. table fixed. to the upper end of the post or standard. Formed through the rear edge of the central portion of the work table is a series of inwardly extending parallel slots 1 through which the blades of the rotary cutter operate.

Formed on the rear portion of the base 1 is a pair of lugs 5 in which is rigidly fixed a short, horizontallv disposed shaft 6, and hinged on this shaft is' the lower end of an upwardly extending arm 7 provided on itsupper end with a bearing 8. This bearing occupies aposition to the rear of the table 3, and journaled for rotation in said bearing is a shaft 9. The left hand end of this shaft is reduced in diameter, as designated by 10, and positioned on said reduced portion is a series of disks 11, the same being provided with sharp cutting edges, and said disks are locked on the shaft against the shoulder be tween the reduced end 10 and the main body of said shaft by means of a nut 12 applied to the end of the reduced portion. These disks which form the rotary cutting member of my improved machine are made in various diameters with the largest disks at the center so that the cutting edges of said disks lie in the arc of a circle. This arrangement is shown in order that phts of equal depth can be formed in the curved edges of the work.

A hood 13 is fixed in any suitable manner to the table 3 and extends over and to the rear of the rotary cutting member or post of the disks 11, and formed through the front wall of this hood is a series of slots 14 which coincide with table 3.

Extending forwardly from the lower portion of the arm 7 is a lu 15, and interposed t e'base 1 is a compression spring 16 which normally holds the bearing 8 on the upper end of the arm 7 at its limit of nnivement away from the ta.-

Leashes blades are adapted to traverse-the slots in 3. In a machine of the class described. a

work table provided with a series of slots, a guard plate provided with Li series of slots corresponding with the 'siots in. the work table, and a rotary cutting head comprising a series of disks having sharp edges that are adapted to move through the slots in the work table and guard plate.

4. In a machine of the class described, a work table provid ed with a series of slots, a guard plate provided with a series of slots corresponding with the slots in the work table, a rotatably mounted shaft arranged to more toward and away from the work table, and a rotary cutting head comprisingaseries of disks fixed onsaid shaft, which disks are provided with sharp edges that pass through the slots in the guard plate and work table when the shaft is moved toward said work table.

5. In a machine of the class described, a work table provided with a series of slots a guard plate provided with a series of slots corresponding with the siots in the work table, a rotatahly mount-ed shaft arranged to move toward and away from the work table, a rotary cut-ting head comprising a series of disks fixed oh'said shaft, which disks are provided with sharp edges that pass through the slots in the guard plate and work table when the shaft is moved toward said work table, and means for normally holding the shaft away from the work table.

6. In a machine of the class described, a work table provided with a series of slots, a guard plate provided with a series of slots corresponding with the slots in the work table, a rotatably mounted shaft arranged to move toward and away from the work table, a rotary cutting head comprising a series of disks fixed on said shaft, which disks are provided with sharp edges that pass through the slots in the guard plate and work table when the shaft is moved toward said work table, and means for moving the shaft toward the work table.

7. In a machine of the class described, a plate provided with a series of slots,'a rotary cutting head comprising aseries of blades having cutting edges adapted to move through the slots in the plate, and means whereby said cutting head is moved toward the plate so that the cutting edges of the blades project through the slots in said plate.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses,
