The present invention relates to dust mops and the like and has. to do with means for jointo the handle,'means for rotating thehead about a'centrally disposedshaft and for locking the head in any one of a plu- This application is a continuation in part of applicants application Serial No. 436,358 filed March 26, l942, for Dust mops, which issued Patent No. 2,325,598.

structures of similar types of to the applicant as In conventional mop's the locking elements, which must be pulled apart to unlock, comprises a pair of platesrelatively rotatable about acommon axis and adapted each to engage'the other by means of vertical apertures and corresponding stops in opposite plates. Whereas, my structure comprises a short vertical collar having oppositely disposed notches in its face in combination with a transversely positioned pivot adapted to engage the notches and to be automatically unlocked. Thus; the combination made possible by the use of a vertical collar, including the mounting of the handle on the collar, provides aunique and simplified structure in compact form.

One object of the invention is to provide a new and unique structure for joining the head to the handle and for easily changing the head from the transverse to the longitudinal position.

" Another object of the invention is to provide means for automatically disengaging'the locking elements in the'structure.

I -;A further object of theinvention is to'provide "a mop having'its head'pivotally connected with the handle means forlimiting the rolling movement of the head about the axis of the pivot.

) And another object of the invention is to provide the required structure in a form combining details and simplicity with utility in a manner to facilitate the production and assembly of parts.

Other objects will be apparent from the drawing and specifications, "In the drawing:

A apart notches 4 are formed in the face of the collar in a manner oppositely disposed notches adapted to engage the pivot 5, the axis of each pair of notches passing through the vertical axis of the collar 3. I

A tubular shaft 6 having a flange I at its lower end and a transverse opening 8 at its upper end is mounted in the aforesaid collar 3 with its lower end extending a substantial distance below the under side of the collar and its upper end extending a substantial distance above the face'of the is mounted on the shaft In between flange Land the under side of the collar.

H With the tubular shaft 6 in place as heretofore indicated the handle lU-and head 2 are connected by forcing the shaft upward to a position where its transverse opening Band openings in plates H register at the top of the collar 3 and inserting pivot 5 through said openings.

It is to be noted that'collar 3, tubular shaft 6 and the handle If! in vertical position have a common vertical axis and that the transverse axis of pivot 5 and the transverse axis of each pair of the notches 4 coincide with said common The handle I0 is provided with plates H at its lower endwhich plates fit over the outside of collar 3. Openings at the lower end of said plates to receive-a pivot 5 and cams l3- at the lower end of the plates are positioned a substantial distance below the openings 12 and are adapted to engage the adjacent plate I of the manner to limit the movement of the head about the axis of pivot 5 and said cams are adapted to lift said pivot out of a pair of the notches 4 when the handle is tilted to a vertical position as in Figures 3 and 4.

The cams I 3 which are rotatable about the pivot comprise a heel M, a toe l5 and a base pivot 5 and a pair of the notches 4 are in locka substantial dis- In order to automatically disengage the looking elements I provide the following means:

(a) The depth of proximately one-third of the pivot 5, that is, the notches are when {the pivot is urged into locking engagement with a pair of the notches approximately twothirds of the pivot the face of collar 3.

pivot 5 may be lifted from the notches 4 as heretofore indicated.

I To change the head from broad to the longitudinal or the transverse or the the pivot registers with another pair of the notches 4 and is urged into locking engagement Or, tilt the It is obvious that details of the invention may be varied without departing from the spirit of the invention.

I claim:

1. In a mop, collar fixed in a mop supporting head, a circular a vertical position to the central portion of the head, a handle rotatably mounted on the collar, a pivot connected with and positioned transversely of the end of the handle, .a

It in contact with plurality of notches in the face of said collar adapted to engage the pivot and spring means for normally urging the pivot and notches into the spring is being adapted and a handle somewhat compressed, said pivot to engage the aforesaid notches, mounted on the pivot.

notches into cooperation and a cam fixed with reference to the handle end and pivot, said cam being adapted to engage the adjaposition. v

4. In a mop, a mop supporting head, a handle pivotally mounted on the head,

5. In a mop, a mop supporting head, a circuin a vertical position to the head,
