BRUSH.

Specification of Letters Patent.

Patented May 10, 19110.

Application filed September 3, 1909. Serial No. 516,106.

To all whom it may concern;

Be it known that I, HARVEY W. HASOY,

of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Brushes, of which the following is a speci fication.

This invention relates to brushes, especially of the type usually called a paint brush, although it is not limited specifically to such use.

One of the objects of the invention is to provide a brush having an improved form of connection between the handle and the bunch or mass of bristles whereby the use of nails or other similar fastenings may be dispensed with.

Another object of the invention is to provide a brush having an improved structure whereby a lesser length of bristles is needed in the ferrule to hold the mass securely.

To these ends the invention consists in the construction and combination of parts substantially as hereinafter described and claimed.

Of the accompanying drawings,Figure 1 is a perspective view of a brush constructed according to my invention, the parts of the brush being illustrated as in the act of assembling them. Fig. 2 represents a transverse section through the lower portion of the handle, the upper portion of the bristles, and the coupling, the members being assembled. Fig. 3 is a view similar to Fig. 2, but showing a modification hereinafter described.

Similar reference characters indicate the same or similar parts in all of the views.

The bunch or mass of bristles a is held by a ferrule b of a cup form; that is, the ferrule comprises not only a band which surrounds the ends of the bristles but also a base against which the bristles abut, the edge of the band portion of the ferrule being preferably bent inward to clamp the bristles as indicated in Fig. 2. So far as described this particular form of ferrule is not new with me and it need not be further described.

Rigidly attached to or integral with the base of the cup-ferrule is a rib 0 extending longitudinally and preferably centrally of the cup-ferrule. The handle a? which may be of any preferred shape for use, has a head 6 which is slightly larger than the adjacent portion of the handle (I so as to Said head is formed with a longitudinal slot 9 in which the rib c of the ferrule closely fits, the connection being such that practically all of the lateral strain on the brush in use is resisted by the coaction of the rib 0 and slot 9.

To connect the handle and the ferrule with its bunch of bristles, and to also strengthen the sides of the head on opposite sides of the slot so as to prevent spreading of the head, I employ a coupling member 72,, said coupling consisting of a band adapted to closely surround and fit the sides of the ferrule b and head 6. As shown in the drawing, the lower edge of the coupling h is slightly turned or bent inward to closely engage the outer side walls of the cup-ferrule. \Vith the coupling having this form, the members are assembled by passing the coupling on to the bristles first over the lower ends thereof, it being customary to employ a temporary paper binder for the bristles to contract them while the coupling is being slipped to the position shown in Fig. 1. Then the ferrule and handle are assembled by forcing the rib 0 into the slot 9 of the handle, until the top of the ferrule seats firmly against the lower surface of the head of the handle. Then the coupling h is slipped upward and its upper edge is slightly turned in over the shoulder f as indicated at h in Fig. 2. If desired, tacks may be driven through the sides of the coupling into the head, but this is not necessary. However, whether such tacks or nails are employed or not, no driven fastenings are passed through the ferrule into the handle head, or through the ferrule into the bristles. And since the sides of the ferrule are re-inforced by the coupling the latter exerts an additional pressure or hold upon the base of the bunch of bristles so that the ferrule may be quite shallow, thereby enabling shorter bristles than usual to be employed, while still giving the requisite amount of length for lateral play or bending of the bristles in use.

I do not limit myself to the specific form form a shoulder f.

1 and 2, it comprises a flat metal piece the sides of which are parallel. But it may have a dove-tail form as indicated in Fig. 3 at c, in which case the slot or groove in the handle head will be of corresponding form in cross section. In this case, the ferrule and its rib Will be first connected to the of the rib 0 as to its cross section. In Figs.

handle head by a longitudinal sliding movement of the rib relatively to the slot which holds it. Then constructed in this form, the ferrule and handle are held firmly together so that they cannot become separated excepting by a relative longitudinal movement, and therefore the ferrule it may be of thinner material, having only suflicient strength to prevent such longitudinal movement by obstructing the ends of the slot. However, it is preferred that in this form the ferrule it shall be made of metal having suflieient strength to reinforce the sides of the ferrule in the same manner as has been described in connection with the other form illustrated. As shown in Fig. 3, the sides of the head, instead of having a decided shoulder, may have beveled sides over which the upper edges of the ferrule are turned or bent as at if.

Having now described my invention, what I claim is:

1. A brush comprising a ferrule halving the bristles secured therein, said ferrule having integral base and side Walls forming a cup, a rigid rib projecting from the base portion of the cup a handle having a head formed with a slot engaging said rib, and a coupling securing the ferrule and head together.

2. A brush comprising a ferrule having the bristles secured therein and having a rigid rib projecting from its upper side, a handle having a head formed with a slot engaging said rib, and a coupling comprising a band surrounding both the head of the handle and the sides of the ferrule, the upper and lower edges of the coupling be ing turned inward to engage both the ferrule and head.

In testimony whereof I have aiiixed my signature, in presence of two witnesses.
