MOP.

Specification of Letters Patent.

Patented Sept. 5, 1916.

To all whom t may concern:

Be it known that I, EDWARD H. TATE, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Mops, of which the following is a specification.

This invention relates to a mop having a substantially triangular frame or head to which a handle is connected and mop filaments of fibrous material depending from said head, the mop being usually operated in a dry condition or treated with a dust arresting composition.

The invention is embodied in the hereinafter described improvements relating to the construction .of the frame, the means for connecting the handle therewith, said means permitting the handle to occupy various angular positions relatively to the plane of the head or frame, to a mop element of improved structure cooperating with'the head or'frame, and to means for securing the mop element to the head or frame.

0f the accompanying drawing, forming a part of this specification: Figure 1 represents a top plan view of a mop embodying my invention; Fig. 2 represents a section on line 2-2 of Fig. 1; Fig. 3 represents a perspective view of the crossbar and handle socket shown by Figs. 1 and 2; Fig. 4 represents a section on line 1-4 of Fig. 1; Fig. 5 represents a fragmentary sectional view showing a part of the neck portion of the mop element; Fig. 6 represents a fragmentary perspective view showing a portion of the mop element as it appears prior to its engagement with the clamp hereinafter referred to; Fig. 7 represents a fragmentary perspective view showing portions of the mop element and a portion ofthe clamp; Fig. 8 represents a fragmentary side view showing theJ end portions of the clamp and the coupling member connecting said portions; Fig. 9 represents a section on line 9-9 of Fig. 8; Fig. 10 represents a side view on a reduced scale of a complete mop embodyn ing the invention, a part of the handle being broken away.

The same reference characters indicate the same or similar parts in all the views.

In the drawings, 12 represents an approximately triangular frame, the outer side of which is grooved, as shown by Fig. 2. Said frame is preferably composed of a sheet metal strip of concavo-convex form in cross section, the ends of said strip being overlapped and united at 13 (Fig. 1) by welding, brazing, or otherwise.

To two of the sides of the frame 12 are pivoted a crossbar having a handle-engaging socket. Said crossbar is preferably composed of a base portion 14 and ak wing portion 15 integral with the base portion, the crossbar being preferably formed by bending a sheet metal blank into the angular form represented by Figs. 1, 2 and 3. The crossbar is provided at its ends with ears 16, preferably integral with the base portion, said ears being perforated to receive hinge pintles or rivets 17 which establish a hinge connection between the crossbar and the frame 12. The said pintles are preferably engaged, as indicated by Figs. 1 and 4, with bosses 18 formed on two of the frame sides, said bosses presenting fiat sides or faces which are parallel with each other and with the ears 16.

The handle socket is preferably a substantially semi-cylindrical sheet metal member 20 having ears 21 which are riveted or otherwise securely connected with the wing portion 15 of the crossbar, said member 20 and wing portion 15 forming a socket which is semi-circular at one side and iiat at the opposite side, as clearly shown by Figs. 1 and 3. The member 2O is preferably embossed at its semi-circular portion to form segmental or interrupted screw-thread portions 22, adapted to engage a corresponding thread formed on the inner end of an elongated Wooden handle 23. The crossbar constitutes a strut which prevents the inward bending of the sides o-f the frame to which it is pivoted. The angular Jform of the crossbar when made of sheet metal as shown and described adds materially to the effectiveness of the crossbar as the strut.

It will be seen by reference to Fig. 2 that the axis of the handle socket is substantially equidistant from the upper and lower edges of the fra-me and that the socket is located mainly within the frame. This arrangement enables the handle to assume the dotted line position shown at the right of Fig. 10, so that the mop may be introduced into a relatively low space, such as the space between the floor and a radiator above the floor. The handle is also adapted to stand at right angles with the plane of the frame to enable the mop to be used on a ceiling, and to stand at various intermediate angles.

My improved mop element as here shown is composed of two facing strips 24 of textile fabric and a body of fibrous strands 25 usually of twisted cotton yarn laid crossvwise between the facingV strips and projecting from the opposite longitudinal edges thereof to form loose brush filaments depending from the frame, as indicated by Fig. 10. |The facing strips 24; andthe intermediate portions of the fibrous strands conwider than the outer wing to enable it to feo conform to the frame 12.

28 represents a triangular clamping strip, which is preferably a fiat-sided strip of steel or other suitable metal, the ends 29 of which are spaced apart, as shown by Fig. 8. Said grooved outer side of' the clamping strip is formed to hold the inner wing of the mop element `neck against the grooved outer side of the frame 12. The

.wings of the neck are united by a longitudinal row of stitches 30, preferably formed after the clampingV strip 28 is interposed between said Wings. rlhe ends of the clamping strip 28 are connected by a coupling member 31, which is preferably a metal bar havthe abruptly bent portion of the mop ele- Yce'A ment neck where the stitches 26 are located projects above the upper edge of the frame 12 and constitutes a cushion guarding said upper edge and preventing it from striking woodwork when the mop is being used. It will also be seen that the outer wing of the Y mop element neck covers the clamping strip V28 and coupling member 31 and prevents these parts from striking the woodwork.

1 Having described my invention, I claim: 1. A mop comprising a triangular open frame, a crossbar pivoted at `its ends to two of the sides of said frame and having a .Y handle socket located mainly within the frame, said crossbar constituting va strut preventing inward bending ofthe sides to which it is pivoted, and a mop element including a neck portion surrounding and clamped upon said frame, and filaments depending loosely from said neck and from the frame.

2. A mop comprising a triangular open frame, a crossbar pivoted at its ends to two of the sides of said frame and having a handle socket located mainly within the frame, said crossbar constituting a strut preventing f inward bending of the Jsides to which it is pivoted, and a mop element including a neck lportion surrounding and clamped upon said frame, and filaments depending loosely from said neck and from the frame, said neck projecting above the upper edge of the frame and forming a triangular cushion guarding the frame.
