BRUSH.

SPECIFICATION forming part of Letters .raient No. 720,847, dated Febmary 17, 1.903.

Application filed June 23, 1900.

o all whom, t may concern:

Be it known that I, JOSEPH R. SANFORD, a citizen of the United States of America, resid-- ing and having my post-oflice address in Winsted, in the county of Litchfield, State of Connecticut, have invented certain new and useful Improvements in Brushes, of which the fol-Y lowing is a description, reference being` had to the accompanying drawings, wherein- Figure l is a general View of a brush embodying said improvement. Fig. -2 is a View I of the device shown in Fig. l in central crossseetion on the plane denoted by dottedlinew.

The object of the improvement is the production of a brush having certain features of novelty and advantage.

A brush embodying this improvement may be of divers patterns and weights and specically applicable to different uses.

In the drawings, t denotes what maybe called the brush-back.

b denotes the hollow teats carried by the brush-back and integral therewith.

c denotes wings extending from either side of the brush-back integral therewith and preferably in the same plane. The brush-back and the Wings are formed from a single integral piece of liexible material, preferably india-rubber or a compound thereof, and molded into shape. These wings are intended to be folded back over the brush and united to form a loop, through which the hand may be inserted to more eifectually grasp the brush when in use. It is very essential that the brush shall be exible in order to adapt itself to the shape of the users hand and to readily accommodate itself to any inequalities of surfaces on which it is used. It is also essential that the wings which form the handle shall not be elasticin the sense that they will stretch, for if they were whenfthe brush is in use the body of the brush would not readily follow the movement of the hand. It is also essential that these wings or handlestraps should be strengthened, particularly Serial No. 21,377. (No model.)

at the point where they join the back. In order to meet these essential requirements, I have incorporated in the brush-back a textile fabric CZ, which extends without break into the wings. This fabric preferably has selvage ed ges,which considerably increase its strength. By this construction I am enabled to produce a rubber brush of the class specified which is thoroughly practical and which is light and strong and durable.

I claim as my inventionl. As a new article of manufacture, a onepiece brush embodying a brush -lback constructed of elastic material and provided with integral hollow teats, wings formed of elastic material integral with each side of the back, with the upper faces lof said wings on a plane with the upper face of the back, said wings adapted to be folded over the back and over-y lapping one another and connected together to form a handle, and a strip of flexible Inaterial molded in the said back and wings and forming an integral part thereof to preserve the elasticity while preventing the stretching of said back and wings.

2. In combination in a brush, a brush-back, Wings formed integral with the brush-back and extending from the sides thereof with the upper faces in substantially the same plane as the upper face of the brush-back, said brush-back and Wings molded in one piece from flexible elastic material, said wings adapted to be folded over the back overlapping each other and connected together to form a handle, and a layer of exible nonelastic material molded in the brush-back and wings whereby the brush is elastic inthe sense that it tends to return to its normal position but is non-elastic in the sense that it will not stretch.
