lNvENToR 7. 5- //c (67777 ATTORNEY United States Patent 3,092,864 LAMESWOOL DUSTER Thomas Stanislaus McCann, Reigate, Surrey, England Filed Apr. 2, 1962, Ser. No. 184,276 Claims priority, application Great Britain Apr. 24, 1961 4 Claims. (Cl. 15-235) The present invention relates to lambswool dusters for domestic and other purposes of the kind in which a piece or pieces of wool bearing skin is or are secured to one end of a rod or like support of wood or other suitable material.

It has heretofore been proposed to form lambswool dusters of the kind referred to by winding helically around the rod adjacent the said one end thereof one or more strips of the wool bearing skin and securing the strip or strips to the rod by tacking or nailing, the strips being secured and wound in such manner that the natural fall of the wool is towards the said end of the rod and the wool at that end is naturally longer than at a distance therefrom. Such prior construction of duster requires that the strips be applied by hand and that the pitch of the helical winding be varied according to variations in the length of the wool in order to impart the required finished shape to the duster. It will be appreciated that this method of construction involves the use of skilled labour and is time-consuming.

A further prior proposal consists in forming the wool bearing skin into a sleeve or tube which can be slid over the end of the rod and secured in position thereon. The sleeve is formed by cutting a rectangular piece of skin and joining the longitudinal edges together by machine sewing. There is thus a seam extending lengthwise of the sleeve or tube and the wool tends to part along this seam thus exposing the seam to view and impairing the appearance of the duster. Furthermore the seam presents a hard edge extending lengthwise of the duster and the parting of the wool uncovers the seam with the consequent deleterious effect on any delicate surface which the seam may engage.

It is an object of the invention to provide an improved duster of the kind referred to and according to the invention the duster is formed of a plurality of separate pieces of wool bearing skin each of which pieces is formed into a tube by sewing together two edges to form a seam extending lengthwise of the tube, the several tubes thus formed being secured in lengthwise succession on one end portion of a rod or handle of wood or other suitable material in such manner that the re spective seams of the tubes are staggered lengthwise of the rod. In this manner there is avoided a continuous seam extending the full length of the assembled skins thereby minimising to a large extent the aforementioned parting of the Wool. Furthermore in the duster according to the invention the previously mentioned tedious and time-consuming operation of winding a strip of skin on to the rod by hand is dispensed with.

It will be understood that the term lamb is used in a generic sense and includes a sheep and hoggett, the term lambswool being applied to the wool of both these animals.

One embodiment of the invention will now be described with reference to the accompanying drawings in which:

FIGURE 1 shows the separate blanks of skin for forming a duster according to the invention, and

FIGURE 2 shows the skins assembled on to a rod or handle.

At a, b, c and d in FIGURE 1 there are shown four pieces of skin which are to be assembled on a rod or handle in the manner hereinafter described with the piece a positioned at the extreme end of the rod and the pieces b, c and d following in sequence lengthwise of the rod. The pieces are generally of rectangular shape but the piece a is formed to have a longitudinally extending tongue '1 and is cut as indicated at 2 on each side of the tongue to provide transverse flaps 3. The pieces are selected according to the length of the wool so that the wool reduces in length from the end piece a to the piece d to produce a duster of the finished shape indicated in broken line at 4 in FIGURE 2. The pieces 0 and d are preferably narrower than the pieces a and b and for convenience in subsequent manufacture are joined together as shown at 5.

The pieces are folded lengthwise and the longitudinal edges of the pieces are joined together by sewing to form tubular sections of an internal diameter such that they can be slidably engaged over the rod, each section having a seam 8 (FIGURE 2) extending lengthwise thereof. The pieces are cut and folded so that when assembled on the rod as hereinafter described the natural fall of the wool is towards the end of the rod.

As shown in FIGURE 2 the tubular sections are assembled on the end of a rod 6 with the respective scams 8 staggered lengthwise of the rod and with the section formed by the piece a at the extreme end of the rod, the tongue 1 being folded over the end of the rod and along the rod so as to cover the seam 8 of the section for substantially the whole length thereof, and being secured to the rod as by a nail or staple 7.

Before sewing the piece a, the flaps 3 are turned in so that they are secured in the in-turned position by the sewing of the longitudinal edges of the piece. The inturned flaps 3 increase the concentration of wool at the end of the rod and it will be apparent that by varying the depth of the flaps the concentration of wool will be likewise varied.

It will be understood that the finished shape of the duster need not be as shown in FIGURE 2 and that by suitably selecting and arranging pieces of skin of differing or the same wool lengths, and by varying the number of pieces of skin, 'dusters of other shapes can be produced.

I claim:

1. A duster in the form of a tube made of a plurality of separate pieces of wool-bearing skin, leach skin having two edges thereof joined together to form an individual tube having a longitudinally extending seam, and a rod on which said individual tubes are mounted, said individual tubes being connected together in longitudinal succession with their respective seams staggered peripherally about the rod, said duster comprising a strip of said wool-bearing skin extending across one end of said rod and lengthwise over the longitudinal seam of the endmost individual tube.

2. A duster in the form of a tube made of a plurality of separate pieces of wool-bearing skin, each skin having two edges thereof joined together to form an individual tube having a longitudinally extending seam, and a rod on which said individual tubes are mounted, said individual tubes being connected together in longitudinal succession with their respective seams staggered peripherally about the rod, said individual tubes being arranged so that the natural fall of the wool is toward one end of the rod, and the pieces of skin forming the tube comprising W001 which differs in length from piece to piece, said pieces being so arranged relative to each other as to give a desired shape to the duster.

3. A duster according to claim 1 wherein the said strip 4 is formed by a tongue integral with the piece of skin forming the said endmost tube.

4. A duster according to claim 3 wherein the piece of skin forming the endznost tube is provided at one end 810,708 Brister Jan. 23, 1906

Claims (1)

1. A DUSTER IN THE FORM OF A TUBE MADE OF A PLURALITY OF SEPARATE PIECES OF WOOL-BEARING SKIN, EACH SKIN HAVING TWO EDGES THEREOF JOINED TOGETHER TO FORM AN INDIVIDUAL TUBE HAVING A LONGITUDINALLY EXTENDING SEAM, AND A ROD ON WHICH SAID INDIVIDUAL TUBES ARE MOUNTED, SAID INDIVIDUAL TUBES BEING CONNECTED TOGETHER IN LONGITUDINAL SUCCESSION WITH THEIR RESPECTIVE SEAMS STAGGERED PERIPHERALLY ABOUT THE ROD, SAID DUSTER COMPRISING A STRIP OF SAID WOOL-BEARING SKIN EXTENDING ACROSS ONE END OF SAID ROD AND LENGTHWISE OVER THE LONGITUDINAL SEAM OF THE ENDMOST INDIVIDUAL TUBE.
