Serial No. 155,814.

ii brush in accordance with this invention, 1); way 0'1. example is illustrated in connectron with a metal mold employed for manufacturing rubber shoe heels and which is indicated at 10 and formed with a pin 10 to provide an opening in the-heel which is employed for the passage of holdfast devices, to secure the heel in position. The deposits of the casting material which have adhered to the wall of a molding cavity or chamber and also to the pin 10 are indicated at 11. The molding cavity or chamber is indicated at 10. In Figure l of the drawing: the brush is illustrated as in aninoperative posi tron, just prior to it performing its function of removing the deposit 11. In Figure 2 of the drawing the brush is shownas in an operative position when employed to thoroughly clean the mold. The brush includes a rotatable shank 1 of any shape or size to conform to requirements of machine,- such as a drill press, lathe, hand drill to which the-brush is to be attached and operated from. By way of example the shank 1 is of tapered contour and cylindrical in cross section.

A brush for the purpose 'set forthand in accordance with this invention includes a shank 1-, which as shown is of tapered contour and cylindrical-incross section, but its Outer terminal portion 1 ofuniform diameter throughout as well as of reduced outer diameter with respect to the remaining portionof the shank; The reduced outer terminal portion lof the shanlr provides a peripheral shoulder 1 and said portion 'l i's provided with peripheral threads 1 The shank 1 from a point-removed from its inner end to its outer end is hollow to providea lengthwise extending chamber-1 which opens at the outer end'of the shank. The closed end of the chamber'1, which provides the inner end wall of the latter, and indicated at 1 constitutes an abutment for one end of a coiled controll ng spring2'for a centering spindle 3, and the latter is provided at a point between its transverse median and inner end with a peripheral boss 3 against which the otherend ofthe spring Q'abuts. The spring: 2 surrounds that portion ofthe spindle '3, between the boss 3 and-the inner end. of said spindle. T he spindle 3 operates in the chamber 1.

The brush further includes a carrier 4 which also forms a bearing for centering the spindle 3. The carrier 4 has its inner portion formed with a centrally arranged socket 4,

.carrier 4 and through said bore 4" extends the spindle 3.

Connected to and extending outwardly from the carrier 4 is .a combined coupling and holder member referred to generally by the reference character 7 and which consists of a cylindrical part 7 of uniform outer diameter, a tapered part 7 which projects from the cylindrical part 7, a shoulder 7" formed on the inner face of the member 7'and positioned at the inner end of the part 7 and internal threads 7 which are formed on the inner face of the part 7 and engage with periph eral threads 4 provided on the carrier 4. The shoulder 7 provides a seat on the inner face of the member 7 interi'nediate the ends thereof.

Arranged within and extended from the member 7, is a brush element referred to generally by the reference character 5 and which includes a cup-shaped head having its bottom provided with a plurality of concentric rows of spaced openings as indicated at 5" and 5'. The head 5 is mounted on the seat formed by the shoulder 7" arranged on the inner face of the member 7. The head 5 is furthermore formed with a centrally arranged opening 5 through which extends the spindle 3.

The brush element further includes a plurality of sets of groups or tufts of cleaning members or bristles carried by the head 5. The number of sets corresponds with the number of circular rows of openings. As each group or tuft of cleaning members or bristles is constructed alike, but one will be described, as the description of one will apply to all the others. The group or tufts will be hereinafter referred to as a tuft and is formed from a plurality of equal length wires 6 arranged in parallelism and of the desired gauge. The wires 6 are bent centrally upon themselves. as at 6. The wires when bent are extended through an opening and have the major portion of their length extend outwardly from the bottom of the head member 5. That portion of the wires positioned inwardly with respect to the bottom of the head 5 is formedin a loop-like manner as indicated at 6". The wires 6 are secured together, at the bent portion thereof by a ring 8 and which also acts as a means to prevent the wires 6 from passing through an opening 5" or 5.

When the brush is in position. for use the holder 7 is screwed up on the carrier'4 and which carries the brush element 5 therewith so that the latter will fit tightly against the carrier 4 and will not slip during the operation of the brush. The rings 8, when the brush element 5 isin the position as stated shifts downwardly within the brush element 5. When the brush element 5 is clamped against the carrier 4 by the adjusting of the holder 7 there is no slipping of the brush element 5 when the brush is rotated. The holder 7 has its lower end engage the bristles 7 and a frictional contact is set up betweenv the bristles and said holder. The brush element 5 is carried upwardly to clamp against the carrier 4 by the shoulder 7 I g The combined holder and coupling me n ber 7, acts as a guide for the brush element, and thetapered part 7 'f of the member 7, presses the tufts towardsthe spindle, 3 and also causes the tufts to rest firmly against the molds during the cleaning operation. The lower end of the spindle 3 is formed with a concavity 13 to receive the pin 10. The smaller end 9 of the part 7' engages the tufts for shifting them in a manner to restfirmly against the spindle 3 and also the work to be cleared. The shank 1, carrier 4,.element 5 and member 7 are moved downwardly on the spindle 3, against the action of the spring-2 and on the downward movement of the holder 7, the brush'element will be moved downwardly or outwardly and beseated in the work to be cleaneQ and when the brush is revolved the adhering casting deposits, will be thoroughly removed I from the mold.

When pressure isreleased upon the shank '1,

the spring 2 will act to elevate the spindle 3 to the position shown in .Figure 'l and which will carry the brush element clearlof the work which has been operated on. -The work referred to is the moldiwhich is to be cleaned fromdeposits of the casting material which have adhered to the mold cavity or other portions of the mold during the casting operation. The spring 2 providesimeans for normally maintaining the tufts-clear of the mold or the work to be cleaned. p

It is thought the many advantages of a brush, in accordance with this inyention for the purpose referred to. can be readily-understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood.that

changes in the details of construction can be had which will fall within the invention as claimed. 7
