Application November 19, 1946, Serial No. 710,753 3 Claims. (01. 15-453 The object ofthis invention is to provide a newv improved form. of mop and mop handle.

Another object of the invention is to form the mop handle with twov sleeves, one having a maleathread and the other having a female thread i which threads engage each other for the purpose of opening or closing. the. jaws of the mop.

Another object of the invention is to form a male sleeve with a jaw swiveled thereon which slides in and engages with theyoke that is attached tothe female sleeve.

Another object of the invention is to permit the two sleeves to be' fully turned on each other and locked in engagement with each other in any desired position.

These and other objectsof the invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings: vReference numeral I. indicates the mop stick which is ordinarily made of wood, 2 indicates the male sleeve with a: thread formed thereon with a; neck 3 formed on the bottom thereof and a head 4 formed on the bottom of the neck. The sleeve, the neck and-the head are preferably all formed integral in one piece. The sleeve {is held on the stick I by the pin 5. In Figures 1 and 3, I have'shown the upper jaw 6 which comprises two plates 5a and 61;. These plates are exaptly alike Each of these has a rectangular slot 1- formed therein in which engages the knurled head 4. Above the slot eaeh'of the plates is formed with a half r und 8a and 8b. Whenthe two plates 6;; and 6b are brought together, these tw al reim n a r und e eck 3 s that the upper jaw is swiveled on the neck 3. The two plates 6:; and 6b are spot welded or rivie l tq et er as ndi a ed a 5 in, 1 2 and la.

On the plates 15a and 6b are formed the teeth L an l wh h en a e t e fibrous t r a of the .mr an h lds it a in e ok I. of the mnhend ei.

.y i ma e s ev ll leer-willed wh h i mounted o n the male sleeve 2 so that either'of them can turn on the other. The female sleeve has female I threads thereon which engage with the male threadsof the male sleeve and the female sleeve is about half the length of the male sleevel "On the lower end of the female sleeve is formed the yoke 16 which yoke is made either integral with 1 thefemale sleeveor is spot welded thereto. This mks 1i f rmed wi h a vzj ha e r ov l i h eroe e xt nd cleara und th ok This yok appear la-F u .4 w ichs ows, a s c o taken entir l ne Aw asin eaied in Fi ure 1. he out r dcfeach late 1 c an 6 of he J w is bentrhalf diamondshapei as indicated at I9 in Figure .4. The; two plates form a diamond shaped moldin when' brought together. This diamond shaped end 19 engages in-the 'V-shaped groove I 8 and slides up janddown therein 'as'the mop stick and-the male Sleeve is turned in the female sleeve. In this way the jaw 8 can be brought-into engagement with the groove in the bottom ofmfthe' yoke I6 or as near thereto as is necessary to clamp the fibrous material with the mop between them and the 'up' and down" movement of the jaw is "secured by turning'the' mop stick to the left or right as the case may be,

0n the bottom of the female .sleeve I1; '1' pro- 1 vide a reinforcing band 2 I" spot welded thereto.

which band appears in Figure 1. It can have a female thread therein if desired or it can be left plain. On the upper end of the female sleeve I provide another reinforcing band 22 which is also shown in Figure 1. This can be threaded or left plain and when set in a predetermined position it can be spot welded or brazed in that position.

This band 22 has an irregular extension 23 formed thereon as shown in Figures and 6. This extension has parallel sides which acts as a guide for a block 24 which slides in and out between the parallel sides. In the end 25 of the extension 23 is threaded a screw 26 having a head 21. The right hand end of this screw is reduced as shown at 28 in Figure 6 and is swiveled in the block 24 so that by turning the screw 26, the block 24 can be moved to the left or right as shown in Figures 5 and 6. The block is grooved so that it rides on one of the male threads of the male sleeve 2. This appears in Figure 6. By turning the knurled head a few degrees, the clamping effect of the block 24 on the male thread is released and the stick in the male sleeve can be turned and when the jaw B has reached its correct position, the head 2! will be turned to clamp the block 24 on the male thread and lock the male thread and the female thread together. This pushes the male sleeve over against the female sleeve and holds the two of them together against turning on each other.

It will be understood that the female sleeve is cut away to form a recess as indicated at 30 and the block 24 always remains loosely engaged with this recess, so that when the block is clamped against the male sleeve, the one sleeve cannot turn in the other sleeve.

In Figure '7 I have shown a modification of this locking device in which la indicates the stick, 2a indicates the male sleeve and Ila indicates the female sleeve and 22a indicates a reinforcing band which is round and does not have the extension shown in Figure 5. The male threads are left flat or mutilated to form a groove or recess on opposite sides of the male sleeve as indicated at 40 in Figure 7. The female sleeve is cut away to form a recess as indicated at 4|. The band is not cut away or mutilated in any way. This band 22a is spot welded to the female sleeve Na and turns with it. When the groove 40 formed by the mutilation of the male threads is brought into line with the recess 4|, the key 42 can be put into the grooves 40, 4'! thus locking the male sleeve and the female sleeve against turning on each other. It is obvious that because the groove 40 is formed on both sides of the sleeve 2a that a half turn of the stick will bring the groove 40 into line with the recess a't 4| so that the male sleeve and the female sleeve can be keyed or locked together.

The male sleeve 2, neck 3 and knurled head 4 are formed in one piece. The female sleeve l1 and yoke I 6 are formed in another.

agonally in the V-shaped groove iii of the yoke 5. See Fig. 8. If necessary the yoke can be cut away at the lower left hand corner and the upper right hand corner to permit this to be done. They are then brought into horizontal position as shown in dotted lines in Figure 8, and at the upper end they are spread apart and passed over the knurled head 4 and broughttogether around the neck 3, it being understood that the male sleeve would then be threaded into .the female sleeve andbroug'ht to the po The

jaws

6a and 6b are brought together and set di-' sition shown in Figure 1 or 9. The two plates 6a and 612 would then be closed around the neck 3 and would be welded together, as shown in Figure 10. The rings 2! and 22 can be put in place on the female sleeve either before 01' after the above operation.

Having assembled the'mop handle in this way and having fixed the'mop stick in the male sleeve, the jaw can be moved up, the fibrous material can be fixed in place in the mop handle over the yoke l6, and the jaw 6 can be moved down to engage this fibrous material. Thereafter the sleeves can be clamped together as above described. The mop is then ready for use. If it is desired to remove the fibrous material and renew it with fresh material it can be done by reversing this process.

I claim:

1. In a mop holder and handle therefor, the combination of a handle, a metal sleeve, a pin fastening said sleeve on said handle, a male thread formed on said sleeve, a stem formed on the bottom of said sleeve and a head formed on the end of the stem, a jaw comprising two similar plates clamped together each of said plates having a half round formed thereon, which half rounds when the plates are clamped together form a collar that is swiveled on said stem and held in place by said head, a second sleeve having a female thread formed thereon, engaging with the male thread on said first named sleeve, a yoke formed on said second sleeve extending below said jaw, V-shaped grooves formed in the sides of said yoke in which the sides of said jaw engage, said jaw being moved up and down in said grooves by the turning of the handle and the first named sleeve in the second named sleeve, means for locking the two sleeves together.
