" sembling the parts, and thereby saving valuable `time and also increasing the durability of the completed article.
1 In the drawing, Figure 1 is a view i-n perspective of a ferrule .looking at the upper side. Fig. 2 is a similar view looking at the under side. Fig. 3 is a transverse section of the ferrule through the body thereof. Fig. 4 is a sectional elevation showing the parts loosely assembled; and Fig. 5 is a similar view of the completed article.
A'represents thehandle, B the bristles and C a ferrule or cap used in the operation of firmly securing the respective parts in their assembled relation.
As this invention'relates more especially to the flat type of brushes, that form is used in illustrating the improvement.
' The ferrule C is an integral fabrication of thin sheet steel and for flat brushes thc contouris of the oval elongated form shown. In the operation of manufacture the single piece `of metal is struck up in the desired form,the center elongated part of the plate beingforced upward or inward to provide a solid imperforate diaphragm 6 dividing the structure into the cupped out receptacles formingthe brush-socket 7 and the handle socket 8. rlhe operation of forcing a portion of the ferrule blank inward or upward in pro viding the diaphragm feature, forms a double wall 9 below the same and a thickened bead edge 1() in the fold of the metal. This double-wall construction affords increased wedges or Awire in securing the different parts together. In the use of thin sheet steel a lighter ferrule can be made, than if cast or i forged, which is another important advantage. The cost of production is also less.
In the operation of making the brush, the butt ends of the bristles are inserted in the socket 7 and bottom or level up on the diaphragm 6. A triangular shaped clamping wedge 12 is then loosely inserted dividing the butt endsl of the bristles through the center, as shown in Figs. 4 and 5. It will be noted that the fixed position of the wedge brings one of the edges or corners 13 straight downward, the two opposite sloping sides 14 and 15 vanishing therein. The wedge is loosely slipped into place as it is not intended to eX- ert an outward pressure, the bristles being .secured by an inward pressure.
The contour and position of the clampingwedge with reference to the binding bead edge of the ferrule is such, that when a pressure is exerted from the outside inward a kink or bend 16 will be formed in the bristles by the pressure against the sloping or undersides of the clamping wedge piece and will prevent any possibility of the bristles becoming loose or Working out. After the center binding wedge is properly inserted the brush is placed in a suitable machine and an inward all around die-pressure is applied to the binding bead edge 1() which bends the same inward and firmly clamps the bristles between the inner side ofthe double-wall of the ferrule and the binding wedge, as shown in Fig. 5. By this means the bristles are compacted in place by frictional contact, no other or separate `fastening being required.
Fig. 4 shows the double wall andibead edge in its normal constructive position for the bunching of the bristles.
The ferrule being capable of a change of form after the bristles are inserted, by setting the bead edge inward makes it possible to more firmly secure the same in place than te wall inclosing the brush socket was rigi The handle is provided with a continuous groove 17 and is secured in place by compressing the upper edge of the single wall 18 1nto said groove, as shown in Fig. 5.
Having thus described my invention, what I claim is- 1. A brush-ferrule, comprising in an integral structure, a bristle-socket, a handlesocket, and an imperforate division diahragm, one of said sockets being inciosed y a double-Wall having a bead edge, and the i other socket ineiosed by a Wali--edge of a singie thickness.
2. A brush-ferrule, Comprising an integrai structure, consisting of a brush-socket, a hand1esocket, and a -solid diaphragzrn von a 'line i between said sockets, the brush-socket being inclosed by a double Wall having a bindingv bead -edgeadapted 'to ybe compressed inward in securing the Ibristles firmly in place.
43. A brush-ferrule of integral struct-ure., l comprising a brush-socket, a handle-socket,
and a division diaphragm, the brush-socket being inolosed by a double Wall having a bead 15 In testimony whereof I have signed my 2Q name to this speciication in the presence of tWo subscribing Witnesses.
