Patented Mar. 10, 1931 UNITED STATES PATENT OFFICE THOMAS CAHILL, or Ann on-n, r nnnsynvenm, essrcrnore' r Josnrn sauna, or- PHILADELPHIA, rnnnsxnvenm SCOURI'NG DEVICE Application filed March 12, 192-9. Serial No. 346,432.

m A further object is to provide a scouring pad holder made up of woodand a piece of spring steel wire, bent in :such a form, that the point of thehook end of the wire, will be directed downwardly at an angle, for-readily forcing the said point into the pad, without touching the pad vwith either hand, and when pushed up against the holder by forcing the handle down, to have the hookturnto compress the pad up against the handle, and at the same time lock the wire in this up-position. Y r a I With these and other objects, my invention resides in certain construction, oneembodiment of which is illustrated-in the drawings, wherein like figures of reference refertol-ike parts, is hereinafter described, itsop'eration V i The wire 21 has two long portions 27 and 28,

is explained; and what 'I claim is set forth. In the drawings, I 1 Figure 1 is a side elevation ofa scouring 30. device embodying my invention, and is shown partly broken away to illustrate the internal construction. p

Figure 2 is a bottom plan of the device shown in Figure 1, illustrating a fragment of circularsteel wool .pad attachedto the holder. r

Figure 6 is in Figure 4.

a top plan of theholder shown In the figures, the circular handle 10, preferably made of wood, is shown to have a central long bore 11, opening belowinto a shallow circular pocket 12, concentric there.-

-to and, greater in diameter than the bore. 11.

The bore 11 opens above into a cylindrical pocket 13, concentric with, but of greater diameter than the bore 11. This pocket 13 opens above into alarger pocket 14 concentric thereto, and in the top of the holder. A conis cal shoulder 15 is formed between the bore 11" and the pocket 13', while a conical shoulder 16 r is formed between thepockets 13 and 14;. The handle 10 has a spherical body 17, terminatingin a neck 18, below which is a flared shoe portion 19 in which is the shallow pocket 12.

About the. neck 18, is the flexible shield 20, which may be of sheet rubber, cloth or any other suitable material.

A wire member 21, is formed to function with the bore 11, the shoulders 15 and 16 and the pocket 12. This member 21 is made of a single piece of spring wire, with a loop 22 at thetop, and is bentto form a heel 23. The

loop 22 is firmly fixedin theslot 24, 0f the cap.

25, and is further secured by a cross pin 26.

integral with a central loop 29. The upper part of the portion 27 terminates. inthe loop 22, while the lower part of the portion 28 terminates in a straight long pointed hook 30,

. in Figure 1, the wire member 21 is shown in a strained or-forced bent position with the portions 27 and 28 nearlyparallel. The circular scouring pad is marked 33.

VV hen assembling themember 21', with the handle 10, having the cap 25, of adiameter adapted to slide intotheborell, the cap. 2 5.

is moved up into thejbore 11, until the hee122 engages the conical shoulder 15. At the same time, the portion 28 bears against the inner circular edge 34, of the pocket 12, and the loop 29 bears, in the opposite direction, against the wall of the bore 11, causing a forced bending of the member 21, that decreases the otherwise normal, unstrained, angle between the portions 27 and 28.

With the pad 33 resting on a firm surface 35, (see Figure 4) and the point 31, of the hook 3O placed a little back of the center of the pad 33, the handle 10 is firmly gripped by one hand of the operator and pressed down, while the fingers touch the top side of the shield 20. The hook 30 is thus imbedded into the meshes of the pad 33, and as the point 31, of the hook 30, bears against the hard surface 35, the member 21 is shoved up into the bore 11 and the pockets 13 and 14. The heel 22, at the same time, travels up and snaps over the upper shoulder 16, due to flexed action occurring in the length of the member 21, as the portion 28, moves up as it bears against the edge 34, straightening out the member 21, putting the same in a strained spring condition, whereby the strain comes in connection with a bearing point at the wall of the pocket 14 and a bearing point at the edge 34:, both these bearing points being on one side of the member 21, and an intermediate bearing point of the central loop 29, against the wall of the bore 11 on the opposite side of the member 21, as shown in Figure 1. Ihe hook 30 then becomes horizontal, drawing the central portion of the pad 33 up into the pocket 12, compressing the steel wool of the pad up against the inverted bottom of the pocket 12, as shown in Figure 1.

To release the pad, the cap 25, in the pocket 14, is pressed radially inward to dislodge the heel 23 from hooked engagement with the conical shoulder 16, and then is pressed downward into the pocket 13, until the heel 23 engages the shoulder 15, and the hook 30 points downward at the angle shown in A Figure l, when the pad 33 can be easily released.

IVith the heel 22 engaging the shoulder 15, the member 21 is prevented from falling out of the handle 10. While the member 21 is of a single piece of wire and is easily formed, the functioning of its parts, in tending to resume their normal positions with respect t2 one another, when sprung from their angular relation, during a longitudinal moven ent within the handle 10, effects the desired releasable attachment of the pad 33 with the handle 10 in a quick and practical manner without touching the hand to the pad 33. The flexible shield affords protecting means to the lingers either when operating on an extended surface or the surface of a thin cylindrical object like the handle of a tea pot or metal cup, in which event the pad is bent around the object being cleaned.

While I have illustrated and described but one embodiment of my invention, changes therein can be made without departing from the spirit and scope thereof, I therefore wish to include all forms which come within the purview of the appended claims.

I claim,

1. A scouring device comprising a pad, a handle having a hole axially positioned therethrough, a shoulder on the wall forming said hole, a bent wire member laterally sprung within said hole, a heel portion at one end of said member and a hook portion at the opposite end thereof extending beyond the lower end of said hole, with the point of said hook below the transverse plane of said lower end ofsaid hole, projecting outward with respect to said hole, said heel portion being 0 adapted for releasable engagement with said shoulder.
