WILLIAM SEVERNS, 0F CHICAGO, ILLINOIS;

MOP-CUTTING MACHINE.

Application filed August 17, 1921. Serial No. 493,013.

To all whom t may camera:

Be it known that I, WILLIAM SEvERNs, a citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Mop- Cutting Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe accompanying drawings, and to the numerals of reference marked thereon, which form a part of'this specification.

This invention relates to improvements in machines for making mops and is especially adapted for use in connection with the .manufacture of a mop and the process of cation herein referred to, but it will be understood that it is adapted to be used with other machines for making mops or the like and is not confined tothe particular process as disclosed in the copending application.

One of the objects of this invention is the provision of a machine adapted t0 properly sever the strands 0f a skein of hank or yarn or the like which has been wound upon a frame in regular order and which will sever this yarn in such a manner as to form it into strands of equal length to constitute the body of a mop. .Another object of this invention is the provision of a machine which has cutting knives adapted to sever such a skein or hank of yarn into strands of equal lengthl to form a mop, a cutting knife being mounted upon each side of the machine and both coacting together to complete the cutting of the' strands in one operation of the machine.

Still another important object of the invention is the provision of a machine adapted to cut yarns intoy lengths to form mops which is adapted to be used with a frame upon which the yarn is wound and 'which is adjustable so that the knives may be adjusted to conform to any particular size of frame adapted to make any size or weight of mop as required, Y

illustrated in the drawings and hereafterVA more fully described.

0n the drawings:

Figure 1 is a top plan view of the machine as embodied in this invention Figure 2 is a sectional view taken on line 2 2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is a plan View of the frame upon whlch the strand of yarn is wound preliminarily to forming the mop.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is an enlarged detail View showing the construction of one of the rotary'A gutting knives ,and the driving means there- Figure 6 is a similar .View of one of the rotary cutting knives showing the means by whlch 1ts position relative to the machine and to the other knife is adjusted.

As shown on the drawings:

T he machine comprises a frame or base 10 having supporting legs 12 and provided at 1ts top with a table or platform 14 upon which the work is placed to be operated upon. Mounted upon a shaft 16 extending transversely of the machine are'a pair of pulleys 1 7 and 19, one for driving and the other a loose or idler pulley connected by a belt -to any convenient' source of power. Slidably mounted on the shaft 16 and keyed by suitable keys or feathers acting in the keyway 21 so as to be rotatable therewith is a beveled gear 18 mounted in bearings integral with and projecting from a downwardly extending support 20 which is held in position by the table 14 and the shaft 16. A similar support 50 is provided for a gear 38 likewise fixed on and driven by the with and be driven by the beveled gears 18 and 38 on-the shaft 16. Integral with the supporting member 20 is an outwardly eX- tending 'lug 30 having a hole therethrough, as shown in Figure 5, and this lhole is internally threaded to correspond with'threads on an adjusting rod 32 extending transversely of the machine, and having its ends mountedin bearings in the frame, as shown in Figure 2. This rod 32 is provided with right-hand threads on one side thereof and, 1f desired, left-hand threads on the other side so that the rotation thereof by means of a wheel or handle 34 will tend to cause the approach or recedence of one or both of the members 20 and '50 to and from each A other, this movement of course including their attached gears 18 and 38 and the circular knives 26ldriven thereby. Adapted to co-operate with the circular knives 26 is a frame 40 upon which a strand of yarn is woundin regular layers to form a mop, the process o f winding this yarn and forming a mop being described in my co-pending ap plication hereinbefore referred to.

A strip or support 42 is sewed to the strands of yarn after they have been wound on the frame 40, as best shown in'Figure 3, and the frame with the yarn thereon is then passed' through the machine and the circular knives 16 act to sever the yarn at both sides of the frame, suitable depressions or grooves being provided in the frame, as

shown at 44 in Figure 4, to provide for the edges'of the knives and their proper coaction with the frame 40. In this way the yarn on the frame is severed in a neat, quick and eiicient manner and the edges are cut so as to correspond very closely to each other when the swatch so formed is folded over to form the finished mop.

The frame 40 may be fed through the machine either by hand or with a .manually regulated mechanical feed if desired, or the feed may be entirely automatic, depending upon the nature of the operation.

The operation is as follows:

After the yarn 41 has been wound upon the frame 40 by any suitable means (the preferred form being shown in my copending application for U. S. Letters Patent on machine for making mops, filed August 17th, 1921, Serial No. 493,014, and the strip or binder 42 sewed thereon, the frame with the attached yarn is then in the condition as mop. The swatch is then doubled into the form' of a mop, as shown in my copending application hereinbefore referred to.

It will be evident that the frames 40 may be made of any size for the construction of mops of -any desired weight or size, and that the` construction of these frames allowing the mechanical winding thereon of a sufficient quantity of yarn is a much more eiiicient operation than that formerly in use whereby an approximate quantity of yarn was taken by hand from a stack of the same, weighed upon a scale and then manually distributed over a strip to which it was afterwards sewed. In the sewing the edges were always left uneven and the product had to be cut and trimmed with a resulting loss of material.' All of these operations being manual consequently involved an expenditure of a good deal of time and expense, and also considerable waste.

The operation of this machine will tend to form a mop'y in a much shorter space of time than has hitherto been required and consequently will turn out a much cheaper product and one which is cut more neatly and therefore --more eiiicient in its operation, inasmuch asW the length of all the strands is exactly the same.

I am aware that many changes may be made and numerous details of construction varied without departing from the principles of this invention, land I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

1. In apparatus for making mops, a frame having parallel grooved sides upon which the yarn is wound, in combination with spaced rotary cutting elements between which the frame is passed with the grooved sides adjacent the cutting elements.

2. In apparatus for making mops, a frame having parallel grooved sides upon which the yarn is wound, in combination with adjustably spaced cutting elements between which the frame is passed with the grooved sides adjacent the cutting elements, and means for simultaneously rotating said cutting elements.

3. In apparatus for making mops, a support, a pair of spaced rotary cuttingelements mounted in said support, means for relatively adjusting said cutting elements, a In testimony whereof I have hereunto subcornmon drive shaft geared to both cutting scribed my name in the presence of two subelements, in combination with a frame havscrlbing witnesses:
