CLEANI NG IMPLEMENT Filed June 25, 1928 Patented Mar. 24, 1931 Fl-ICE ALDO LAZZARIN I, OF ASTORIA, NEW YORK CLEANING IMPLEMENT Application filed June 25,

This invention relates to brooms and in particular to one which can be manipulated to clean corners and about the legs of furniture.

A particular object of the invention is to provide a push broom or the like, the construction of which will permit the brush portion being swingable relatively to the handle stick so that easy operation in sweeping between or under furniture is permitted, and through the medium of which construction, corners and other inaccessible places may be readily swept.

A further object of my invention is to provide a construction for permitting the broom portion to be thrown at an angle to the handle stick which has few parts, which can be manufactured cheaply and which will operate efficiently to permit the sweeping operation.

A still further object of the invention isto provide a broom which is swingable but in which a locking member is provided to prevent the same from being swung relatively to the handle of the broom.

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in the various modifications in structure and relation contemplated, a drawing depicting as two preferred forms have been annexed as a part of this disclosure and in such drawing, similar reference characters denote corresponding parts throughout all the views, of which, I

Figure 1 is a top plan view of my improved broom showing the use of the same at the corner of an article of furniture, the view illustrating how the broom portion may be swung at an angle relatively to the handle stick.

Figure 2 is a View in sectional elevation of the lower end of the handle stick and broom showing the connecting parts and illustrating the latching mechanism.

Figure 3 is a section taken on the line 33 of Figure 2.

Figure at is a view in perspective of the base and bracket members of the broom, and

Figure 5 is a view of a modified form of my invention.

1928. Serial 1e. 288,210.

Referring to the drawing in detail, 5 indicates a broom back which may be of any desired shape and arranged to hold the bristles 6, or brush portion. It is of course understood that my invention is equally applicable to mops and other cleaning implements as it is to the push broom in connection with which it is illustrated.

The back of the push broom has secured thereto, a base plate 7 which, through the medium of the screws 8, is secured to said back 5. Through the medium of a suitable rivet 9, the base plate is joined to a bracket member 11 whose ends are bent at an angle as illustrated in Figure 2 and provide upstanding jaws 11 and 12, both of which are rounded at their top, the latter being provided with a series of serrations 13 for a purpose to be hereinafter described. The jaws ,7

11 and 12 are joined through the medium of the pin 14 whose function it is to hold between the jaws 11 and 12, the flattened end 15 of the sleeve 16 which is made of metal and which encompasses the lower end of the handle stick 17 The sleeve 16 is provided with an opening 18 through which projects the end of the latch 19 or dog, the end thereof being' arranged to engage in the serrations 13 so that the handle 17 may be held rigid with the broom or in any angular position relatively thereto.

I The dog 19 is pivoted as at 20 in the sleeve 16 and is operated through the medium of the rod 21 which lies in asuitable slot 22 cut in the handle stick 17 at its lower extremity. This rod 21 is movable longitudinally and its upper end is turned outwardly as at 23 and passes out through the slot 2 1 of an adjustable collar 25. This collar is knurled as at 26 to provide a convenient finger hold so that it can be freely revolved upon the handle stick 17. The sleeve 16 is maintained in po: sition through the medium of the suitable brads or screws 27 and the collar 25 is main tained in position on the handle stick 17 and at the sametime permitted to have free revolving movement by the brads 28. The cam slot 2 1 provided in the sleeve 25, it will be noted, is further from one end of the sleeve at one of its extremities than at the other,

thus providing the proper cam motion for the rod 21 so that when the sleeve is revolved, it may draw upon the rod 21 to throw the dog 19 into one of the serrations 13.

During the use of the broom, the dog 19 will be out of engagement with the serrations and the pivotal connection afforded by the pin 14 of the handle stick with the bracket will permit the broom to be swung to an angle relatively to the handle stick 17, the latter of which is provided with a curved portion 29 to facilitate the twisting of the handle 17 to throw the broom 5 to any angular position desired, in a horizontal plane.

In order to make the construction less costly, I have illustrated in Figure 5, the use of a piece of metallic strap 30 which is passed transversely of the broom back 31 and is secured thereto through the medium of the screws 32, the strap being provided with openings 33 which. when the strap is inplace. are adapted to register with the openings 34 that are drilled into the broom backs 31. These openings 34 are arranged to receive the inturned ends 35 of the jaw prongs 36. These jaw prongs are formed from a single piece of heavy wire which is looped as at 37 within the flattened end 38 of a piece of tubing 39, a rivet 40 being provided through the flattened portion 38 to prevent pulling out of the jaw piece from within the flattened end 38 of the tubular portion. The tubular portion may be secured in any well known manner, such for instance, as by the pin 41 to the wooden handle stick 42 which is also curved at its upper end, as illustrated in Figure 1.

It is quite evident that by providing double sets of openings 34- at the opposite sides of the broom back 31, that the broomcan be used from both sides and wear of the bristles 43 will be even.

The jaw prongs 36 are held a predetermined distance apart so that they' will have to be snapped into the openings 34 and through the openings 33 of the metal strip 30. In this way they will. maintain a firm grip on the broom and will not accidentally become separated therefrom during use.

It is quite evident also that with this type of construction, the broom may be thrown at an angle to the handle so that the cleaning of corners and inaccessible places is facilitated.

It isqnite evident therefore that I have provided an improved swingable push broom which has few parts, which can be manufactured at small cost and which can be used to advantage in cleaning corners and about the legs of furniture as well as for cleaning in the usual manner.

It, is also evident that in the construction shown in Figure 2, the bracket can be reversed f-rom the position illustrated so that the opposite sides of the brush bristles can be Worn down.

It is quite evident also that the most important feature of my invention is the pivotal mounting of the broom relatively to the handle 17 which permits, upon revolving movement of the handle stick, the angular disposition of the broom itself.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is 1. A cleaning implement comprising a back, a handle, means for pivotally attaching the handle to the back at a fixed acute angle to the horizontal plane of the back, said attachment permitting the back to swing on the ground when the handle is partly revolved and permitting the handle to be folded down longitudinally of and against the back.

2. A cleaning implement comprising a back. a handle, means for attaching the handle to the back by articulate joint, such that the hinging line of the joint be at the right angle to the length of the back but at a fixed acute angle to the horizontal plane of the same back, this assemblage causing the back to swing about its middle on the ground plane when the handle is imparted a partial turn around its axis in either direction.

3. A cleaning implement comprising a back, a handle, means to detachably secure the handle to the back providing an articulate joint such that the hinging line of the joint is at right angles to the length of the back but at a fixedacute angle to the horizontal plane of said back, and such that the handle may be made to fall lengthwise of the back.

4. A cleaning implement comprising, a back, a bracket thereon having extended portions. one of which is serrated, the bracket being disposed at a fixed acute angle to the horizontal plane of the brush, ahandle, a sleeve connected to one end of the handle, a pin for pivotally joining the'bracket and the sleeve, said pin being disposed at right angles to the back, and a latch in the sleeve for engaging the serrations whereby the pivotal movements of the handle relatively to the back may be controlled.

In testimony whereofI afix my signature.
