FLOOR-CLEANING DEVICE.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application filed May 22, 1917. Serial No. 170,250.

To all whom it may concern:

Be it known that I, FRANK O. Lrsrnn, a citizen of the United States, residing at Altoona, in the ounty of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Floor-Cleaning Devices, of which the following is a specification.

This invention relates to floor cleaning devices and has special reference to improvements in mops, or devices of a similar. character that are adapted to be operated with a cloth or brush for the purpose of cleaning windows, floors, walls or ceilings.

The primary object of this device is to provide a combined improved mop and brush holder whereby the mop or brush is firmly held in position by a resilient element, which is designed to grip the mop or brush such that the operation is positive and the parts rigidly held, while at the same time, the release of the cleaning element is easily accomplished when desired.

Another object of this device is to provide an improved mop and brush holder having a resilient mop or brush holding portion that is actuated by a spring that is designed to offer a substantial and gradual increasing resistance, as the elements that hold the mop or brush are separated.

A still further object of this device is to provide a mop and brush holder having a stationary jaw and a spring actuated movable jaw, the stationary jaw having means for attaching a handle for the convenience of the operator, as well as to provide means for holding in a fixed position the ends of the resilient element which controls the position of the movable-jaw.

With these and many other objects in view which will be more readily apparent as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts as will be hereinafter more fully pointed out, illustrated and claimed.

It will be readily apparent to those skilled in the art to which this invention belongs, that the same is susceptible to some structural change or modification without departing from the spirit or scope of the invention, but a preferred and practical embodiment of the same is shown in the accompanying drawings, in which- Figure 1 shows a side elevational View of '14, or similar means.

the present invention together with a mop cloth attached thereto.

Fig. 2 shows a side elevational view of the present invention having attached thereto the usual form of scrub brush. a

Fig. 3 shows a plan view of the mop and brush holder with the operating handle removed. 7 v Fig. l shows a front view of the cloth and brush engaging elements.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

In carrying out this invention, I use a sheet metal-preferably galvanized ironto construct the stationary and handle engaging portion designated by the numeral l0,while the same thickness of galvanized iron is preferably used to construct the movable jaw portion, designated by the numeral 11. a

The stationary aw portion 10 is designed to have a curved contour that is adapted to fit the handle 12 at the point 13 where it is attached to the handle by means of rivets The uppermost end 15 of the stationary jaw 10 is turned back upon itself, as at 16 to provide hollow spring receiving ears, which construction readily forms a substantial fulcrum and fastening device for the upper jaw clamping spring 17, as shown in Figs. 1 and 2 of the drawin'gs.

The jaw clamping element 17 is preferably made such that the ends thereof are each secured to the stationary jaw 10, while adjacent the ends there is provided a coil 19 which is positioned in such manner that the coil is wound at each time the jaw 11 is moved away from the stationary jaw 10. The transverse portion of the spring 17 is designed to cross the movable jaw near the mop engaging portion 20 which is provided with sawtooth-like surfaces 21 that readily hold the mop cloth.

For the purpose of engaging the brush, as shown in Fig. 2, the mop engaging portion of the stationary jaw 10 is preferably formed in a half circle, as indicated at 22, which construction readily permits the frame of the brush to be grasped.

In order to provide means for setting the brush 23 at the proper angle with reference to the operating handle 12, there is provided an auxiliary brush holder 24 which is adapted to grip the brush as shown at 25. The holder 24: is preferably provided with a slot 26 and pin 27, the pin 27 being positioned in the movable'jaw 11. The brush clamp 24:, by virtue of the slot 26, is movable thereby permitting in a practical manner the introduction of brushes of different widths.

Without further description, it is thought that the many features and advantages of the present invention will be readily apparent.

I claim:

1. A mop orbrush holding device including a stationary jaw, a movable jaw pivoted thereto having an article engaging portion disposed at substantially right angles to the body of the jaw and provided with a slot, a spring for forcing the movable jaw toward the fixed jaw, and an auxiliary brush carrying jaw mounted in the slot of the movable jaw and having a slidable engagement with the inner face of the said movable jaw.

52. A mop or brush holding device including a stationary member having a fixed gripping jaw at one end and hollow spring receiving ears at the other, a handle rigidly secured to said stationary member, a movable clamping member pivotally carried by the stationary member, a spring for placing the movable member under tension, said spring being of substantially Ushaped form and having its end portions coiled and fastened in the spring receiving ears of the stationary member While its free transverse portion exerts a clamping pressure on the movable member, and means carried by the movable member for engaging a brush.

3. A mop or brush holding device including a stationary member having a gripping jaw at one end and integral tubular spring holding ears at the other end, a movable clamping member having a gripping aw at one end and pivotally connected at its opposite end with the stationary member adjacent the spring holding means thereof, a spring for said movable member having its end portions engaged by the spring holding ears of the stationary member, and an extension jaw element carried by the movable member. 7

l. A mop or brush holding device including a stationary member having a gripping aw at one end and having its opposite ends turned downwardly to form tubular. spring receiving ears,a movable member also having a gripping jaw at one end andpivoted at its other end to the said stationary member, a substantially U-shaped spring having a coil portionadjacent each end and also having the extremities thereof engaged within the tubular ears of the stationary member, saidspring having its transverse portion bearing against the outer face of the movable member, and an extensible brush engaging element carried by the movable member and located at the inner face thereof, V r i 5. A mop orbrush holding device including'a stationary member having a gripping jaw, a spring tei'isioned clamping member having a gripping jaw and provided with a longitudinal slotinthe body thereof anda horizontal slot in the jaw thereof, and ancX- tension brush grippingelement having its body portion passing through the slot in said jawof the movable member and also carrying a pin slidably engaging the longitudinal slot in the body of the movable member.

In testimony whereof I affix my signature in the presence of two witnesses.
