UNIVERSAL UTILITY EXTENSION MOP Filed March 12, 1936 lNI ENT0 R. G gyenbyeizier BY {ITTORNEY Patented Oct. 25, 1938 umrEof s rATss UNIVERSAL UTILITY Ex'rENsioN MOP [earl-F. Guggenbuehler,'New York, N; Y. Application March 12, 1936,- Serial No. 68,416 2 claims (01. sta 19$ The main object of this invention is to. provide a mop having an extensible mop end which may be flexibly projected in amanual manner under low slung furniture. g

Another object of the invention is to provide an extensible mop which may be telescoped into a staff and projected from the staff fiexible in all directions, in order to clean and dust beneath low slung furniture. I I j Still another 'obiect of the invention is to provide an extensible mop having means thereon forremovably fixing the mop headto theextensible portion of the staff. i

The above and other objects will become apparent in the description below in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing Figure 1, is a prospective view showing all of the members iricluding the locking unit for securing the mop head to the staff. a

Figure 2 is a side elevational view of the com pletely assembled mop; i

Figure 3 is a top plan view of the extensible portion of the mop showing the bed plate secured thereto.

Figure 4 is a cross sectional view taken on line 44 of Figure 2, showing the entire locking mechanism in place.

Figure 5 is a cross sectional view taken on line 55 of Figure 3.

Referring in detail to the drawing the numeral l0, indicates a substantially rigid stafi preferably composed of some suitable wood. At the upper end of the staif a rubber bumper composed of some suitable porous material is mounted in a slip fit. This bumper is indicated by the numeral At diametrically opposite positions on the sides of the stafi longitudinal canals or channels I2, are formed. These channels extend from approximately the middle of the staff to one end of the same. Slidably mounted on the stafi. is a sleeve I3, which has its edges curled as indicated by the numeral M, in order to fit more securely the hand grip. Within the channels I2, flexible fingers l5 and I6, are removably mounted. These fingers extend lengthwise in the shaft channels and at one end are formed into a right angle turn so as to form a U-shaped rod. The fingers l5 and I6 register in suitable openings in the sleeve I3, and after being fitted into these openings are peened over as indicated by the numeral thus securing the fingers of the sleeve. At the lower ends or the extremities of the fingers which project from the staff channels the fingers are joined by a branch Ill. The plate I9, is fitted over the extending portions of the fingers |5 and I6, and the'branch l8. This plate is secured to the fingers and branch by providing ears 2|], which latter are curled about the fingers and branch. AtDne position on the plate IS, a transverse slot 2|, is provided for purposes which will be more fully hereinafter described; A second plate 22, is mounted upon plate l9, by passing rivets thru openings 23,- in plate 22, and thru-openings 24, in plate l9. This plate 22, is e156 provided with a transverse slot 25, which latter cooperates with and is superimposed over the transverse slot 2|, in the plate 1-9. A slidably cage'z'a, having guide tongues 21, at its side :is'

movable upon the plate 22.- This cage at one end is provided with a semicircularly looped saddle 28, in whose passageway 29, a rung 30, of amop head 3|, is swivelly mounted. This cage 26,- is provided with a bayonet slot 32, which latter co: operates with the transverse slots 2| and 25, of the plates l9 and 22 respectively. The fourth memberirialing up the locking mechanism for securing lock head'2l, to the fingers |5 and I6, is a rubber covered guard 33, which is slipped over member 26, and is provided with a bayonet slot 34, and a rather large saddle 35.

In assembling the device the sleeve I3, is slidably mounted upon the staff 0, and the fingers I5 and I6, are inserted into the channels |2, formed in the staif. After the fingers are connected to the sleeve it is possible to extend the fingers by means of normally moving the sleeve 13, and flexing these fingers in any direction. The fingers I5 and I6, and the branch I 8, has a plate I9, secured thereto by means of curling the ears 20, about the fingers and branch. The plate 22, surmounts plate I9, with one slot 25, superimposing and being aligned with the slot 2|, to the plate IS. The cage 26, is then placed upon the plate 22, and the guard'33, is mounted snugly upon the cage 26. A wing bolt 36, is then slipped thru the transverse slots 2| and 25, and thenv thru the bayonet slots 32 and 34, and the wing nut 31, cooperating with the wing bolt, is used to secure the members in either locked or released position to each other. It is to be noted that the bayonet slots are composed of a long longitudinal passageway 34 and 32, and an intersecting slot 38. When the wing bolt 36, is shifted transversely into slots 2| and 25, the cross section of the wing bolt enters into the longitudinal portions of the bayonet slots 32 and, of the cage and guard respectively. This shifting of the wing bolt permits the slidable functioning of the cage and guard so that the portion 39, of the saddle will be open to permit member 30, of the mop head to be released and removed or replaced. By reciprocating the cage and guard and again returning the .wing bolt 36, to its original position the cross section of the wing bolt will enter into the portion 38, of the bayonet slots 32 and 34, and will thereby lock the cage and guard in secured position shown in Figure 5, in which the portion 30, of the mop head is entirely enclosed in the cradle 39, and the mop head is ready for use.

The device may be equipped in a modified form.

with a spring such as indicated by the numeral 23a, and a rubber guard 24a, may be fitted under members [5 and I6, as indicated in Figure 5. Surmounting the sleeve a shell 25a, is located. This shell is hollow and has a spring projected plunger 25a, therein, which is adapted to enter an opening in the center of the staff intermediate its length. Another opening 21a, may be formed.

in the lower end of the staff so that when the plunger 26a, engages this opening 21a, all of the parts of the device will remain in extended position.

It is to be noted that certain changes in form and construction may be made without departing from the spirit and. scope of the invention.

I claim:

1. In a cleaning device of the character described, the combination of an extensible handle including an elongated U-shaped rod, a plate rigidly secured to the base portion of the U- shaped rod, said plate having a tranverse slot formed in its surface, a cage member having guide means for permitting longitudinal slidable movement on the plate, said cage member including a bayonet slot formed in its surface having longitudinal and transverse portions, the latter normally coinciding in position with the transverse slot of the plate, a looped saddle projecting from the end of said cage member for receiving the connecting endof a cleaning implement, a

rubber guard member conforming in shape and design tothe cage member and in normal assembled condition covering the latter and having a bayonet slot in said guard member to coincide with the bayonet slot of said cage member, and a connecting means extended through the slots of the plate, the cage member and the guard member, so that when said connecting means projects through the transverse portions of the slots the looped saddle will engage over the plate so as to positively connect the cleaning implement with the extensible handle, whereas when the connecting means is in alignment with the longitudinal portions of the bayonet slots the cage member with loop saddle can be slid forward on the plate so as to release the connecting end of the cleaning implement.

2, In a cleaning device of the character described, the combination of a handle, a plate having rigid connection with one end of said handle, said plate having a transverse slot formed in its plane surface, a cage member positioned over the plate and having guide means for permitting longitudinal slideable movement of the member on the plate, said cage member having a bayonet slot formed in its surface, said slot comprising longitudinal and transverse portions, the latter normally coinciding in position with the transverse slot of the plate, a looped saddle projecting from the end of said cage member for receiving the connecting end of a cleaning implement, and a connectingmeans extended through the slots of the plate and the cage member so that when said connecting means projects through the transverse portions of the slots, the looped saddle will engage over the plate so as to positively connect the cleaning implement with the end of the handle, whereas when the connecting means is in alignment with the longitudinal portion of the bayonet slot, the cage member with looped saddle can be slid forward on the plate so as to release the connecting end of the cleaning implement.
