" BY E dward Patented Dec. 2, 1941 UNITED STAT FICE 1 Claim.

This invention relates to mops in general, and particularly to means for securing the string or yarn to a head and to attach the head to a handle.

More specifically, the invention relates to a mop which is particularly adaptable for use by roofers for applying pitch to a roof.

The primary object of the present invention is the provision of new and improved means for tying or securing the mop strands of yarn or string to a head and detachably connecting the head to a handle.

Another important object of the invention is the provision of a mop which has a threaded member engaging a loop which surrounds the yarn so that the yarn will be held tightly in position and the head can be quickly applied to or detached from the handle.

A still further object of the invention is to provide a mop which is capable of withstanding hard usage and relatively high temperatures, which is provided with means for holding the yarn in position and preventing the yarn or strings from shedding, andwhich is adaptable to be replaced whether the mop is hot or cold.

Numerous other objects and advantages will be apparent throughout the following specification.

The accompanying drawing illustrates a selected embodiment of the invention, and the views therein are as follows:

Fig. 1 is a detail elevational view of the mop and embodying the invention;

Fig. 2 is a detail sectional view taken longitudinally through the improved mop;

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 2; and

Fig. 4 is a detail sectional view on the line of Fig. 2.

The particular mop herein disclosed for the purpose of illustrating the invention comprises a body 5 made up of a plurality of strands of yarn or string passing through a loop 6. The loop 6 is preferably made of wire, which extends through an opening 7 formed in the head 8 of an attaching bolt 9. The free ends H3 and ID of the wire loop 6 are wound about the body of the bolt 9, as indicated at H, Fig. 3. A nut l2 threadedly engages the threaded end l3 of the bolt 9 so as to clamp the yarn tightly in the loop 6 between the head 8 of the bolt and the nut l2. A disk washer M is preferably arranged between the under side of the nut l2 and the coiled ends of the wire loop 6 to permit easy rotation of the nut and to cause the washer to act as an Opposed, 3

pitch and then spread over the area.

clamping surface with respect to the nut head 8.

The bolt 9 is made of a length suificient to permit the threaded end l3 to extend a substantial distance beyond the top of the nut 12 so as to make a removable connection between the mop head and a handle socket IS.

The handle socket I5 is preferably made of metal and may comprise a metal tube having an upwardly flared or hell shaped upper end IE to detachably receive a handle I1. Therefore, the socket l5, which comprises a handle portion, and the detachable handle I7, is referred to herein as a handle member. A nut or other member I8 is arranged in the lower end of the socket member I5 and is securely fastened thereto by welding or otherwise, the attachment herein shown comprising pins I9 passing through the walls of the socket member l5 and into the body of the nut 18. The nut I8 is immovably and nonrotatably secured in position, and where the socket member is round, as herein shown, the periphery of the nut It will be round also. However, the nut is secured in the socket member in any desirable manner so as to prevent removal or rotation thereof. The nut I8 is provided with an internal threaded bore or opening 20 to receive the projecting threaded end l3 of the bolt 9. The handle is applied to the mop head by merely turning the handle and its attached socket member to effect a tightening screw threaded engagement between the bolt end 13 and the nut I8.

In the roofing art, hot pitch is applied over the roof area by the use of a mop dipped into the hot The rough, severe usage given the mop causes the mop to wear out in a relatively short space of time, and therefore a new mop head must be applied, and it is desirable that the change be made as quickly as possible. When the mop is hot and covered with hot pitch, a considerable problem has been presented to the workman in applying a new mop head quickly. The present invention, however, overcomes the difiiculty and disadvantages inherent in conventional mops, because a new head can be applied quickly and readily by merely turning the handle to release the handle from the nut. Also, when the mop is cold, the pitch will adhere and stick to the various parts of the mop, making the change of the new mop head to the handle very difficult in the conventional mops. In the present invention, however, no difiiculty is encountered in loosening the handle from the head. Moreover, the structure is such that the contraction and expansion of the metal parts will not afiiect the quick removability and application of heads to handles. Moreover, the parts are generally standard and can be purchased in the open market and quickly applied and assembled.

The mop head itself comprises the bolt 9, the wire 6, the washer l4 and the nut l2, and they are delivered as a unit. Therefore, when a mop is Worn out, it is an exceedingly easy operation to unscrew the socket member and its cooperating handle from the end of the bolt 9 and apply a new mop head. The socket member I5 is relatively long and, being made of metal, will not wear out or deteriorate, even though it is constantly coated with pitch, both hot and cold.

The parts are rugged and are adaptable to hard usage and are not affected by the temperature.

The invention, therefore, provides a mop of relatively few and simple parts, which can be quickly and readily assembled, and which will withstand hard usage to which roofers mops are subjected.

Changes may be made in the .iorm, construc- .tion and arrangement .of the pants without .departing from the spirit of the invention or sacrificing any of its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claim. The invention is hereby claimed as follows: A mop including a mop head comprising a bolt having a threaded stem and a head at one end of the stem, said head being formed with a diametral channel, a length of wire having its mid portion mounted in said channel and opposite end portions extending oppositely from said head and bent to form arcuate loops, the extremities of said end portions being coiled about the stem of the bolt to hold the wire in place on the stem, a bunch of mop strings held by and within said arcuate loops, a nut on the bolt for holding the coiled extremities of the wire in longitudinally adjusted position on the stem,

and .a tubular handle-socket member having a threaded collar secured on one end thereof and adapted for threaded connection on said stem outwardly of and in position to lock with said nut to secure the map head on the handle-socket member.
