ADJUSTABLE HANDLE Application mea January 25, 192s. .sriai No. 549,431.

This invention relates to an improvement in brushes, mops and closely analogous articles,` and relates more particularly to handle connecting means for such articles.

The principal object of the present invention is to provide in an article of the indicated character, practical and improved means for connecting a handle with a cleaning element, so that the handle may be releasably held in different angular positions with re- Y spect to the cleaning element, to enable a person to more conveniently and expeditiously carry out cleaning operations.

With the foregoingand other objects in f view, the invention resides in the particular provision, construction and functions of the parts hereinafter fully described and illustrated in the accompanying drawing, in which- Figure 1 is a plan view showing the present invention applied to a brush, only portions of the bristle carrying head and the handle beingA shown. Y Y f Fig. 2 is a sectional view taken on the line 2`2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 3-3 of F-ig. 1.

Fig. 4 is a sectional View taken on the line L1'*t of Fig. 1, showing the handle vertically disposed in full lines, and horizontally disposed in dot and dash lines.

Referring now more particularly to the several views of the drawing it will be apparent that there is shown the cleaning element of a brush which consists of a stock or head 10,

and the usual bristles 11 secured to the head 1 10. Cleaning elements of this type are made of different sizes, and some are extremely long in order to move in contact with a large area of a floor for instance.v

In order that such cleaning element may be disposed at the handle designated 12, to enable a person to more conveniently, effectively and expeditiously carry` out cleaning operations, particularly in out-of-theway places, there is provided between the handle 12 and the head 10 means presently to be described. An attachment 13 is employed which is adapted to be connected with one end of the handle 12 bolt 22 different angles with respect to 26 has a normal tendency to exert which will be inltherforml ofi-"a stai'or rod. The attachment 13 is ofintegralconstruction and includes a clamp 14 adapted to embrace Y the handle end, a suitable clamping,element` A 15 being uesd for setting up the clamping action, and a fastening element such as a screw y 16 servesfor preventing turning movement of the attachment, Theattachment `13also includes members eachof said members 17is so formed'as to provide a slot 18, a toe 19, a sole 20, and a heel 21. Abolt 22 is arranged onthe'head 10 and serves as an arbor or pivot. A metallic disk 23 surroundsthelbolt' 22 and is secured to the head 10. A pressure member 24 is arrangedgon the above the disk 23, and said member 24 has arbors or trunnions`25 which are arranged diametrically opposite each other in axial alignment. The arbore 25 are respectively freceivable'in the slots 18 in the members '17.

-A compression spring 26 surroundsthe bolt 22between a cap 27` anda flanged disk 28. The disk 28 is arranged on the bolt 22, is in contact with the member"r 24,and `serves toy vhold the lower end of the springf26 in place.

Thebolt 22 extends through 'a hole in the cap 27 and the cap is heldin place by a'washer 29, anda wing nut 30, the latter adapted for` threading engagement with the upper threaded end of the bolt 22. The cap 27 has slots .31 which respectively accommodate themembers 17 and permit pivotal movement thereof, and therefore 'pivotal movement of the handieia.

From the foregoing it will be apparent that there has beendescribed an `arrangement of fparts whereby thehandle may be held in different angular positions with respect to theV head 10 ofthe cleaning element, and may lalsobe disposed in any` radial position with respect thereto .so as to be disposed laterally with respect to the'head 10, or in longitudinal alignment withrespect thereto. rl`he handle i 12 maybe held vertically disposed, inwhich case, the toes 19 will be in engagement with the disk 23, as shown in Fig. 2. 4The spring i p y a downward pressurelwhich will be imparted tothe inem- 'bers `171th`rugh the niember`24.' vThe handle 17 carried" by` the` clamp' 14a, and'arranged in spaced. relationship, and" 12 will be releasably maintained in this position. By placing one foot on the head 10, the handle 12 may be moved to a substantially 45 angle, in which case, the soles 2() of the members 17 will be in engagement with the disk 23, as `shown in Fig. 2. Likewise the handle 12 may be moved to a position substantiallyparallelwith the uppenface of the head 10, in' which case the heels 21 will be in` engagement with thevdisk 23. It will also be understood that the handle,l2L may be disposed in any radial position regardless of its angular position.

A scraper 32 is held in place on the cap 27 by the wing-nut and Y a screw 33. The

,scraper 32 serves for removingv mattei-stuck to surfacesto becleaned.
