Nelson, Oakland, Calif., assignors to Qalifornia I Gotten Mills Company, Oakland, Calif. Application November 29, 19 12. seiial No. 512,286 ZGlaims. (01.15 229) f This invention relates to a roorers moi: of the type used for applyineand for spreading not tar on roofs.

Heret'ofore mops of this type have been produced, the structure of the diiferent mops being similar in'certain respects, such as in the employrnent of a straight Wooden stick that serves "as a handle and as a support for the mop head. A metal tube is ordinarily secured to the outer end of the mop stick and the mop head that is of cotton cords or yarn is secured to a projecting end of the tube. The purpose of the tube is to prevent burning or charring of the outer end of the mop stick by the hot tar when the amp head is dipped into such tar. In most of these prior structures the mop yarn is secured by a wire to the metal tube, and not to the stick. Considerable diflic'ulty is encountered in tightly securing the yarn to the tube, particularly where the mop head isrelatively large. Also the tubes must be perforated for the v'virswith the result that the hot tar gets between the mop head and the stick and the Stick is not only charrd'or burned, but

this tar makes it difficult to remove the map- 'head-seenring Wire for replacing a mop head.

jAttem'ptsto overcome theseobjectiohs have res'ult'e'd in making up special mop heads provided with a metal eye or hook for engagement. With a hook secured to the end of the amp stick. A

ihetals'leeve reciprocahle on the mop stickis then forced against the mop head to hold the latter rigidand to prevent burning Of the end Of the stick. These attempts have been fairly satisfactor'y, but have precluded the individual operator from making up his own mop head from cohveritional lengths of yarn to suit himself. Also the conventional structures have not entirely stopped burning of the stick and do not provide the strength desired, or the economy in manufac- 'ture that is a'quite' important consideration.'

The principal object of this invention is to provide a structure that overcomes the above mentioned objectiohs, and which mop is very easily manipulated for replacing the mop head. Also there is'no need in my structure for providing specially made up mop heads with eyes or hooks secured thereto, or for tightening or bending wires in order to secure the mop head in place for use. Another object of my invention is the provision of a mop that is economical to make and to use. The economical use resides in the fact that the only part-that requires replacement in use is the mop yarn. There are'no wires, metal bands, or thelike,- that require replacement.

m w a 4 Fig. 1 is an elevational View of an assembled mop ready for use, the stick and head being broken in length to accommodate the View to the sheet. p I m Fig. 2 is an emerged, :rragmentary view or the inop-head-s'e'curin'g means separated from; the mop head, the. view being partially section and partially in elevation and with themop at ri-ght angles to the position fof' tlie mop in Fig. 1. v

Fig. 3 is a sectional view take'hbh line 3" 3 of Fig.2. v V j In detail, the map stick I, which is of World and straight, is provided with a cylindrical; tubular sleeve 2 t an ifecipfocable oh the oiiter end portior'i thereof. Sleeve 2 is of metal and is adapted to fit the Stiek 1 rather til'b'sely, but not so close as to prevent relatively easy sliding of the tube on the stick. The endof the stick oppdsite said outer end ortion thereof is eitposedahdprovidesahanme for holding By the operat r. Ordinarily this ei'iposedpiirtioh of the stick may be from'ahout tv'vo tdthree times the meteor tube 2 or stem three feet; ambush it be lon er or shorter seeming us the reunitemerits of the job to be dohe. r

The niop head ispref ably refilled-iron lengths" of conventional fhOp yarn, such as iiitlie io'rf'r'i, 6f cotton core, string, em; and tvh'ih leh'gths'a're' secured to the stick by in or a apbeai u shapea holder or remove? heavy pring tviie providin legs 3 and a 'cl'ci'se'd end portion 4 The portions or said" legs "at their free ends are" bent toward each other for" forming laterally extenuing projections 5 J The outer "end liqrtioh of the stick lis formed on two of its opposite sides with a pair f 'greoves outer end oi the stick. i N

The legs 3 or theinop-hea noiaerar pf form length and ear lhgth 1'11 that the end portion 4 of theh'cilde'r' 'will (as: end transverse y of hole'l that are nearest the outer end of-the mop stick. For a light mop head, the projections 5 may be in the hole I most remote from the outer end of the handle. For a medium mop head, the said projections may be in the hole I that is between the above mentioned holes.

It is thus seen that the operator may make up a mop head to suit his desires, using similar lengths of mop yarn, or a combination of different lengths, and any desired amount of yarn.

The wire mop head holder is preferably formed so that the legs 3thereof will tend to spring apart as indicated at III in Fig. l in dot-dash lines, unless held substantially parallel in grooves B. Thisfacilitates the replacement of burned or worn out mop heads.

, In securing the holder and a mop head thereonto the stick I, the legs 3 of the holder are placed in grooves 6 with projections 5 on said legs .in the recesses or hole I that will bring the head nearest to the outer end' of stick 7 I. The tube .2 is slipped toward the handle portion of stick I so as to unc yer the grooves and holes I inprder to makethis operation possible. After the legs'3 are in grooves B as above explained, the sleeve 2 is moved axially of stick I toward the mop head funtil 'theile'gs 3 are enclosed therein, thus holding said legsfin the grooves B and also holding ,it'he projections 5 in the desired hole I,

I 'The outer end of sleeve 2 is preferably bell- ,shap'ed as indicated at II, so that the yarn that q o iex'tends betweemthe outer end of stick I and 'the end portion [of the holder will be enclosed .therein, Thefree, annular edge of the bell shaped .part IIwill verytightly engage'the yarn and im anent: the yarn within said bell-shaped 'par't will be so compacted as to preclude'the hot itarin whichthe mop head is dipped from passing a) stick I; When the bell-shaped part I of the sleeve encloses that portion of the mop il'ie'ad above described the outer end of stick I is within the sleeve 2 and as the sides of said sleeve "andsaid part II thereof are imperforate, it is 'seen'that no hot tar can reach the outer end of the stick I to char or burn the latter. When the sleeve 2 is retracted from the mop head to release. the legs 3, the bell-shaped part II will, of course, move with the sleeve to the position I2 indicated in dot-dash line in Fig. 1. U In order to. secure the sleeve 2 and its bellshaped end II in the operative position shown in .liig. l, the sleeve ispreferably formed with a slot I3 extending longitudinally thereof from the .end edge of the sleeve that is remote from the :mophead. This slot extends toward the part II only a small distance sufiicient to enable drawing Y the edges of the slot at the end edge of the tube toward each other'a suflicient distance to enable a tight gripping "of the stick by the tube adjacent "its said endedge. Opposed ears llrigid with 'said sleeve are provided at opposite sides of said slot I3 at the open end of the latter, and a screw ,I5may extend through an aperture in one of said le ars" into threaded engagement with a threaded f laperture the other ear for drawing the edges of the slot toward each other and consequent pping of the stick.

The tube 2 with its bell-shaped end II, when in the position indicated in Fig. 1, functions to hold the mop head rigid relative to the stick I and centered on the axis of the latter. Also the stick is thoroughly protected from the hot tar into which the head may be dipped, even though the mop is dipped into the tar so far that the tar covers the bell-shaped part II and part of the sleeve 2,

The replacement of a burned or worn out mop head merely requires loosening screw and slipping'of the tube 2 and part II on stick I until I .said part II reaches position I2. The holder and mop head then automatically will fall from the stick. As legs 3 of the holder spring apart when released, the old mop head is easily cut from the holder, or slipped off the latter and a new head can be readily placed on the holder. In some instances several holders are made up by an operator in advance to enable quick replacement of a mop head without waiting for the old one to cool, and in other instances the operator may have different sizes of mop heads made up for work in difierent places one. job. The changing from one mop head to another is very easy and quickly done by virtue of the structure herein described.

The extreme rigidity and tightness with which the 'mop head can be held by the sleeve 2 and its part II is largely dependent upon the capacity of the wire holder to hold onto the mop stick when the part II of sleeve 2 is forced against the mop head. The degree to which the said part can be forced against the mop head determines the effectiveness of the seal that the compacted yarn provides in the part I I for preventing passage of hot tar to the handle. By applicant's structure, it will be seen that where the wire of the mop head holder is fairly heavy, as is the case here, the part II can be driven against the mop head with great force without loosening the hold of theholder on the stick. Thus no delicacy need be observed by the operator in tightening the sleeve and part II against the mop head, and a tight seal can be insured always, as well as a rigid mop head.

Having described the invention, we claim:
