UNITED STATES I WILLIAM S. RAUTH, OI' WOODHAVEN, NEW YORK.

CUTTDTG DEVICE.

Application filed April 10, 1922. Serial No. 551,161.

To all whom it may concern:

Be it known that 1, WILLIAM S. RAUTH citizen of the United States, and resident of Woodhaven, in the county of Queens and State of New York, have invented certain new and useful Improvements in Cutting Devices, of which the following is a specification.

This invention relates to cutting devices in general, and particularly known as rotary cutters.

The prime object of my invention is to provide a device of this sort adapted to. be used for cutting cloth singly or in layers or any other material, as for instance, paper leather, and even sheet metal.

A further object of my invention is to provide within such device, a rotary cutting element, so disposed as to permit my device to pass through the cut made thereby.

- n important feature of my invention is to so construct my device as to superimpose the bulk of the body of my device above the cutting element, so as to permit a free movement of my device in any desired direction,

but offer the least possible resistance to such movement toward the material to be cut.

A further object of my invention is to provide means whereby my device may be readily operated in a manner similar to that employed in operating shares.

A still further-object of my invention is to provide a foot or glide disposed at the lower part of the frame of my device, so constructed as to enable the operator to pass it below the material to be out and facilitating the directing of'the cutting by my device along predetermined lines.

The foregoing and still further objects will be more fully apparent from the following description and the accompanyi drawings, forming part of this specification, and in which:

Figure 1 is a top view of a preferred form of my device.

Figure 2 is a side elevation thereof, partially in section.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4 is an enlarged detailview "partially in section, and taken on line it-45: of Fi re 2.

igure 5 is a cross sectional view taken on line 5-5 of Figure 3. v

Figure 6 is an enlarged partial detail view of one of the preferred friction clutch devices, forming part of my invention.

Figure 7 is a cross sectional detail view through such clutch device.

Figure 8 represents a cross sectional View.

' in a foot or glide member 12, provided with a pointed end 13 and havin a slot 14 in which plays a rotary disk-s aped cutting element 15. The latter is rotatably mounted in an extension 16 of the frame body.

It will be seen that the bulk of the frame body is superimposed above the rotary cutting member 15 which feature will be explained later on. Rotatably mounted on pin 17, which is held against rotation by subpin 18, is a dish-shaped fly-wheel 19 provided with a sleeve portion 20 and a bushing or other anti-friction device 21, as may be clearly seen in Figure 7. Within the body of the fly-wheel there is provided a gear indicated at 22.

The fiy-wheel is prevented from disengagement from pin 17 by means of a screw 23, 'or any other convenient means. Upon sleeve 20 of the fly-wheel there is provided a clutch pinion 24, shown in detail in Fig. 6, which is equipped with recesses or depressions 25 adapted to house rollers 26 which bear against sleeve 20 when pinion 24 is turned in anti-clockwise direction. on thus turned the fiy-wheel is caused to turn also in that direction and actuates the pinion 27 of rotary cutting member 15, causing the latter to revolve in clockwise direction.

Attached to the housing at 28, and extendin into the pocket extension 29, is an operatmg handle 30, havinga gear segment 31,

and is adapted to oscillate about attaching point 28.

The teeth 32 of the gear segment engage the teeth of pinion 24, and when handle 30 is moved in upward direction, teeth 32 turn pinion 24 in anti-clockwise directio 11. In order to cause segment 31 to assume 158 upward position, as shown in Fig. 2, a spr ng member indicated at 33 is provided which forces the segment to always revert to its upward position.

,Due to the friction roller clutch arrangement in pinion 24, the latter is adapted to turn idle in clockwise direction when segment 31 travels upwards. In this manner the operator may swing the handle 30 toward handle 11, thus causing fly-wheel 19 to operate rotary cutting element 15, and when the operator releases his grip upon han dle 30, the latter moves in downward direction and pinion 24 glides over sleeve 2t), without engaging the latter, while permitting the fly-wheel to continue in its anti-clockwlse rotation. In this Way the cutter Wlll continue to rotate for a considerable period of time after the handle 30 has been released.

It will be observed that the entire operating mechanism of my device is disposed above the cutting element 15 so as to permit my device to pass through the cut material without obstruction.

For this reason not only the fly-wheel 10, but also the frame body is generally dishshaped, and as may be seen, has the appearance of a so-called stream-line construction.

The feature of permitting free operation of my device above the material to be. cut is very important, as it facilitates the handling of the entiremechanism.

In Figures 8, 9 and 10, there 1s shown a modified form of the driving mechanism of my device, where another friction clutch is em loyed.

In i ure 8 there is shown a fly-wheel 34 provide with a central depression 35 and an annular recess 36 with which registers a driving disk 37 provided with a central sleeve 38 and a pair of lugs 39. Within the depression 35 there are provided two segmental members 40 and 41 prov1ded w1th ins indicated at 42 and 43, respectively.

hese pins engage a pendulum member 44, the lower end 45 of which is engaged by 1ugs39 of disk 37.

A spring member 46 holds the three members 40, 41 and 44 in proper relation to each other. The pendulum member 44 is provided at its center with a recess 47 adapted to engage the sleeve 38 of disk 37 whereby members 40, 41 and 44 are centrally held within depression 35.

Sleeve 38 of disk 37 passes through the central opening 48 of the rear wall 49 (Fig. 8) of fly-wheel 34, and permanently attached to its protruding end is a pinion 5O engaged by the teeth 51 of segment 52 which latter forms part of handle 53 pivoted at 54.

When ha'n le 53 is operated inion 5O rotates and causes the rotation of isk 37. The lugs 39 willmove the pendulum member 44 into the position shown in dashed and dotted lines at 44. Throughthis movement members 40 and 41 are thrust against the wall of depression 35, frictionally engaging the same and causing therefore the fly-wheel 34 to rotate.

When handle 53 is moved in opposite direction pinion 55 is moved in opposite direction and takes with it disk 37. Thus lugs 39 bring the pendulum member 44 into its original position, thereby causing members 40 and 41 to disengage the wall of depression 35 while permitting the fly-wheel to continue in its rotation.

It is obvious of course that any other device may be employed to cause the unrestricted rotation of the fly-wheel in one direction, while the operating handle 30 is moved up and down. In all events, however, the operating mechanism must necessarily be superimposed above the cutting element 15 in order to readily facilitate the operation of my device in following the patterns according to which the material is to be out.

An important feature of my device is also the glidable foot extension adapted to contact with the table whereupon the material to be cut is placed.

While I have shown in the drawings, a specific construction of my device, and particularly the working mechanism thereof, be it understood that changes may be made in its construction as to size and various arrangements of the operating mechanism within the scope of my invention, for which I claim:

1. A rotary cutting device, comprising, a substantially circular frame havlng a tapered, longitudinally slotted forward extension, a dished fly-wheel rotatably associated with the frame, and forming with the latter a substantially closed casing, a rotary cutting element operatively connected with said fly-wheel, and means for actuating the latter in one direction only.

2. A rotary cutting device, comprising a substantially circular frame having a tapered, longitudinally slotted forward extension, a dished fiy-wheel centrally associated with said frame, and forming with y-wheel rotatably mounted at the center of the circular body of said frame, and forming with the latter a substantially closed casing, a rotar cutting element operatively connected with said fly-wheel and extending partially into the slot of said frame-extension, an operating mechanism disposed between said frame and said fl wheel and adapted to rotate-the latter 1n one direction only.

4. A rotary cutting device, comprising, a substantially circular frame having a coneshaped pointed extension provided with a longitudinal recess, a fly-wheel rotatably and centrally mounted with said frame, the fly-wheel comprising a dished member with its edge turned towards said frame, and

forming therewith a substantially closed casing, a fly-wheel operating mechanism disposed within and between said frame and .said fly-wheel, a gear driven rotary cutting element'mounted upon the frame and partially extending into the recess of said pointed extension, and means for causing the operating mechanism to drive said flywheel in one direction only.

Signed at Cedarhurst, in the county of Nassau and State of New York, this 7th 25 day of April, A. D. 1922.
