Application filed September 1, 1920.
T0 aZZ whom it may concern:
Be it known that I, RUDoLr Lone, acitizen of the United States, residing in Jenkintown, Montgomery county, Pennsylvania, have invented certain Improvements in Means for Cutting Fabrics, of which the following is a specification.
My invention relates to improvements in machines for cutting fabrics in given lengths from a piece or roll, which is plain or hemmed at each edge. v
One object of the invention is to provide a machine which will cut fabric in pieces of a given length and to provide means for guiding the fabric to the cutter so as to cut the goods substantially onthe line of the threads. 1
A further object of the invention is to guide the fabric by the hems and to provide a reciprocating cutter located in a rotating roll.
My invention also relates to certain improvements in details of construction, which will be fully described hereinafter, reference being had to the accompanying drawings, in which:
Fig. 1 is an end view of my improved fabric cutting machine;
Fig. 2 is a front elevation of the upper portion of the machine;
Fig. 3' is a front elevation at one end of in the cutter.
ig. 4 is a plan view of themachine; Fig.- 5 is a sectional view of the line 5-5, Fig. 6, illustrating the details of the cutter; Fig. 6 is a sectional view of the line 6-6,
'Fig. 5;
Figs. 7 and 8 are diagrammatic views illustrating my invention; and
Fi 9 is a sectional pers aective view il' lustrating a modification.
Referring to the drawings, 1 is the base of the machine mounted on legs 2 of any suitable design. On this base are two housings 3 for the feed rolls 4c and 5. In the present instance, 7 is the driving shaft adapted to suitable bearings on the legs of the machine. 8 is a sprocket wheel around which Specification of Letters Patent.
ratenteaaul 4, 1922. Serial 407,453. 7
passes a chain 9, which also passes around a sprocket wheel 10 on the journal 11 of the wheels 12 and 13.f Other means of driving the rolls may be used without departing from the essential features of the invention. The roll 5 is hollow, as shown in Figs. 5 and 6, and is slotted at 14:.
15 is a rotary cutter arranged to travel in the slot and to cut the fabric against the roll 4. This cutter 15 is mounted onacarrier 16, which is adapted to a shaft 17 extending the full length'of the roll 5 and is guided by rods 22 projecting from a block 20 slotted to receive the longitudinal rod 18. Adjusting screws 19 on a block 20 bear against the rod 18, and springs 21 are located on the guide rod 22 between this block 20 and the carrier 16. Thus the cutter is yieldingly mounted on the roll 5.
On the end of the shaft 17 is attached a rack section 23 with which meshes a pinion 24 ona shaft 25. A smaller pinion 26 on this shaft meshes with the teeth of a'segment 27 carried by an arm 28 pivoted at 29 to abracketBO and actuated by a cam 81 on the shaft 7, as clearly shown as Fig 3. The coupling between the shaft 17 and rack section 23 is such that the shaft can turn freely with the roll 5. In the present instance, I have shown only one means of operating the cutter, but other means will readily suggest themselves.
In order to guide the fabric to the cutter and to stretch it while being guided, I provide two wires 32, each wire being bent, as shown in Fig.1, so that it can be held in position. The wires are adapted to be passed between the primary feed rollers 33 and and between guide rollers 35 and 36. The guide rollers. 36 are mounted in slides 37 adapted toguideways in the frame of the machine, whiletheguide rollers 35 are carried by bearings 38 pivoted at 39 to the slides 37 and held yieldingly in position by springs 10. In advance of the rollers 33 and 34 are guide rollers 41 carried by arms 42 and held by springs 43. The slides 37, and the rollers carried thereby, place tension upon the fabric and, in the present instance,
slides 37. While I have shown certain means i for applying tension to the fabric, other chineis used in the manufacture of handkermeans may be resorted to without departing from the spirit of the invention.
The operation is as follows: When the ma '33 and 34, and between the tension rolls 35 and 36 the latter rolls being flanged. As these rolls are carried by the slides, they stretch the fabric and hold it taut, so that,
- when it passes between the rolls 4 and 5, it
is gripped by these rolls and immediately after the fabric is gripped the cutter is inickly reciprocated and severs the fabric. his cutter is operated at intervals so that a handkerchief blank of sufficient length is cut from the fabric each time'the cutter is operated. Then the feed rolls draw in a given length of fabric and the cutter again acts to sever the fabric. After this operation, the other hems are made, completing the handkerchief.
In 'Fig. 9, I have illustrated a modification, in which rollers 35 and 36 are roughened to engage fabric that has not been hemmed and which it is desired to cut in given lengths.
These rollers are mounted on slides provided with tension mechanism.
I claim:
1. The combination in a machine for'cutting fabrics, of means for severing the fabric at predetermined intervals; and means in advance of the severing means for guiding and placing tension on the fabric.
2. The combination in a machine for cutting fabrics, of means for guiding the fabric at each edge; tension means engaging the edges of the fabric; feed rolls; and means for severing the fabric at predetermined intervals at the feed rolls, the tension means being in advance of the severing means.

8. The combination in a machine for cutting a fabric provided with a hem at each side, of feed rolls; a reciprocating cutter carried by one of said rolls; a bent guide wire at each side of the machine, the fabric being threaded onto the wires at the hems: apair of primary feed rollers; a roller at each wire in advance of the primary feed rollers; and means for placingtension on the fabric between the primaryfeed rollers and the main feedrolls.
