Howard Dustless-Duster 00., Boston, Mass, a Corporation of Massachusetts 1 Application 'May 8, 1931. serialNo. 535,921

7 Claims.

This invention primarily relates to mopsof the so-called yacht, or round type, in which a bundle of strands of fabric, or yarn is Connected to a handle and is adapted for use either when wet or dry'.

As mops of this type are frequently used as a dusterabout furniture, it is particularlyv desirable that all metal' parts, which may be employed' in connecting the fabric to the handle, be shielded, so that damage will not be caused by striking these metal parts against surfaces which are easily marred. For this reason it has been customary to bind a bundle of fabric about thehandle in a manner to avoid the use of metal attaching means. t

Some of the objections tothis method are that the manufacturing cost is objectionably high, the connection is often unreliable, and the fabric cannot be easily renewed when it becomes deteriorated e V The objects of my invention are to provide a simple and effective device for detachably connecting a bundle of mop fabric, such as yarn, to a handle in a manner to produce a mop of type above referred to, in Which all metal parts used in connection therewith will be ef fectively covered or shielded, and which will enable the fabric to be readily connected to the handle at small expense and will enable the fabric and its connecting means to readily be connected to, and'disconnecte'd fromv the handle, so that these parts may be sold separately and the fabric may be easily renewed when it becomes deteriorated without providing anew handle.

I accomplish these objects by means ofthe construction hereinafter described and as illustrated in the accompanyingdrawing in which:

Fig. 1 is a perspective View of a mop connecter embodying my invention.

Fig. 2 is a view, partly in perspective and partly in section, of acOmpIete mop in which the connecter is employed.

Fig. 3 is a detail view of one of the ing members.

Fig. 4 is an end view of the connecter.

Fig. 5 is a sectional view at line 5--5 of Fig 2..

As shown in the drawing, the means forv connecting the bundle of strands of yarn a to the handle b, comprises a pair of semi-cylindrical members 0 and d which, when placed in position with their edges in engagement, form a tubular socket, which may be'uniform, or tapering in diameter, and is adapted to receive one end-portion of the handle. .,'Each member is preferably provided with internal projections, e which are helicallyfl arranged to form an internal screw thread, the portion of thehandle which is to be inserted therein being provided with a corresponding external screw thread i.

Two pairs of lugs c and c are formed integrally with the members 0, the lugs of each pair being arranged to project from the edges of the member at points which are directly opposite each other, each lug being curved'reversely with relation to the side of the member from'which it extends, to form a concave face on one side which faces oppositely to the concave side of the member. Two pairs of lugs 01, d are also formed integrally with the member d and extend from the edges thereof similarly to the lugs 0, 0 to. provide concave faces which are disposed oppositely to the concave side of the member at.

.Said lugs, are. also spaced apart and arranged 7 so that, when the edges of the members are engaged, the lugs (1 will fit closely between the lugs c and c and the lugs d will occupy. the space between the lug c and the adjacent end of the. socket, so that the socket members will 30 be locked against relative longitudinal moveinent by said lugs; The lugs are also arranged so that the concave faces formed on the lugs at either.v side of the socket provide, in effect, the sides. of a cylindrical passage, the faces of the lugs on one member being disposed oppositely to those on, the other member, and the lugs on one member crossing the lugs on the other member asthey extend from the edges of the members as shown in Fig. 4.

A yoke g is provided, which is preferably f formed from a stifi round Wire bent in U-form, to provide parallel end portions and a connecting semi c'ircular middle portion, the diameter of thewire being sufficiently less than the diameter of the cylindrical passage included by the concave sides of the lugs c,. c d, d to permit the same to be slid into said passage when the members 0, d are held in assembled position, so thatthe wire will act as a key to lock both edge portions of the memberstogether. 7

Thestrands from .Whichthe mop is to be formed are cut to approximately the same length, and a bundle thereof, of suitable size, is provided and arranged with their corresponding ends adjacent and then the middle portion of the bundle is pressed into the yoke ,9, after which the end portions of the yoke are inserted in the passages between the lugs of the mem-' bers at one end thereof, andxforced therethru until their ends emerge at the opposite ends of the members or socket formed thereby. The yoke and the socket are forced together until the strands of the fabric are tightly clamped between the end of the socket and the middle portion of the yokeand then the extreme end portions of the wire are upset, or bent laterally into engagement with the adjacent ends of the lugs c or (1 so as to lockthem to the, socket, against withdrawal.

The preferable arrangement for locking the yoke in clamping position which is shown consists in providing each end lug d with a recess in the side edges thereof next the end of the member, into which the portions 9, at the endsof the wire of which the yoke is formed are bent, as shown in Fig. 1 and in dotted lines in Fig. 5. The members 0, cl will thus be locked together i by the end portions of the yoke in a position in which they form a tubular socket, in which position the internal projections e therein form segments of an internal screw thread therefor, so that, by providingthe handle with a corresponding external screw thread, the mop and handle maybe securely connected by merely screwing the handle into the socket.

A further clamping effect may be secured by forcing the end of the handle against the fabric held bythe yoke, but the clamping action between the yokeand the end of the socket will usually be sufficient to hold the fabric securely.

H With. the above described construction the' metal parts of the connecting' means are so thoroughly embedded in the yarn or fabric of which the mop is composed, that alldanger that they will be'engaged with surfaceswhich they might otherwise damage is avoided. The connectingmeans, comprising the two semi-cylindrical members and the wire yoke, may all be madeat small expense, as the members 0, (1 may be entirely formed stamping them from sheet metal, and the yoke merely consists of a length of stiff wire bent into U-form.

While the wire yoke might be removed by merely bending back the end portions, so that the yarn forming the mop might be replaced,

it is not the intention that this shall be done, as the yarn or fabric already attached to the connecter may be supplied for renewal at but a slight increase over the cost of the fabric, and it is the purpose to supply the trade with the fabric attached to the connecter'separate from the handles. v

It will be understood that the members forming the socket may be made in frustro-conical form, as well as'in cylindrical form, without departing from the; invention as clain1ed,,although the form shown is considered preferable.
