C. A. SCHACHT SPRAY HEAD Filed June 4, 1932 Patented July 24, 1934 UNITED STATES PATENT OFFICE This invention is a novel improvement in spray heads, and the principal object of the invention is to provide a resilient bumper ring adapted to be positioned upon the spray head to prevent the metal part of the spray from coming in contact with enameled sinks, bath tubs and the like, and to protect articles such as dishes etc. from injury by contact with the spray head when in use; said ring being so designed as to project sufliciently beyond the metallic spraying face so that in event the sink drain should become obstructed with grease, sediment, or the like, the spray head can be placed over the drain of the sink and when the water is turned. on a tight connection will be formed between the spray head and drain by the ring so that the water will be forced under pressure into the drain to clear the pipe of such obstruction; also by having this rubber ring protrude beyond the face of the metal portion of the spray head the face of the spray head is prevented from coming in contact with the sinks and the like.

When the hose is attached to the faucet it is only necessary to hold the spray on the drain of the sink, and a spray of water will be-forced into the drain pipe to keep the drain absolutely free from sediment and grease and the like, and by having the rubber protrude beyond the face of the spray head a vacuum is set up between the head and drain so that it is very easy to hold the spray in place even though the full pressure of the water is used.

Heretofore spray heads have been fitted with rubber bumpers usually of circular cross-section which do not protrude beyond the spraying face of the spray head, but such rings soon become loose and worthless and such rings provide no protection for the metal face of this spray head; and my novel ring is an improvement over the old rings, as my ring will protect the spray head and also protect the spraying face where the water comes out, and when this spray is placed over the drain in the sink and the water is turned on, the

water will not escape between the sink and the ring at the side of the spray.

My spray head is particularly adapted for use in bathrooms for shampooing hair or washing dishes and the like.

I will explain the invention with reference to accompanying drawing which illustrates several practical embodiments thereof, to enable cthers familiar with the art to adopt and use the me; and will summarize in the claims the novel of construction, and novel combinations which protection is desired.

In said drawing:

Fig. 1 is an elevation of a spray head showing one form of resilient ring mounted upon the outer spraying end of the spray head, the ring being shown in section; and the spray head being applied to a sink drain.

- Fig. 2 is a view of the spray head and ring showing a modified form of ring.

Fig. 3 is a similar view showing a further modifled form.

Fig. 4 is a sectional view of a further modified form of ring, detached.

Fig; 5 is a view showing the ring illustrated in Fig. 4 applied to a spray head.

Fig. 6 is a sectional view of a still further modifled form of ring, detached.

Fig. '1 is a view showing the ring illustrated in Fig. 6 applied to a spray head.

As shown in Fig. 1 the spray head A is of usual form having its upper end contracted to form a nipple A for attachment of the rubber hose 13 leading to the faucet connector. The lower or outer end is materially widened and is provided with the usual perforated plate A forming a spray face for diffusing the water passing through the head. Adjacent the outer or lower end is an annular rib A extending around the spray head, the metal adjacent the rib being convex as at A.

My novel bumper ring preferably comprises a rubber band 1 of annular shape, preferably of substantially rectangular cross-section, the inner wall 1a and bottom face 10 of the ring being flat and disposed substantially at right angles to each other; while the outer face of the ring is preferably rounded as at 1b. Within the irmer wall of the ring 1 is an annular groove id for receiving the annular rib A of the spray head, whereby the ring 1 will be securely locked thereon, the upper inner corner of the ring abutting against the portion A of the spray head. The ring will be made somewhat smaller in diameter than that of the rib A so that the ring will be stretched in mounting same thereon, and the resiliency of the rubber and the engagement of the rib A in the 1&0 groove 1d securely locking the ring in place. The lower face 1c of the ring 1 protrudes below'the face of the perforated spray plate A .whereby the spray head may be placed upon aflat surface such as a sink C without the plate A touching such surface.

The rubber ring 1 will act as a bumper or a protector and prevent the metal parts of the spray head from coming in contact with enamel sinks, bath, tubs and the like, and as the lower end of 0 the ring 1 protrudes below the face of the plate A, the face of the spray A cannotcontact with the sink or the like. As the rubber projects below the face of the spray head when the hose B is attached to the faucet, the spray head may be held down over the drain D to permit water to be forced down into the drain pipe to free same from sediment, grease and the like. As the rubber extends beyond the face of the spray it creates a suction so that it is very easy to hold the spray in place even though the full pressure of the water in the main be used. The double contact of the ring 1 with the spray head A forms a double lock so that the ring cannot become readily disengaged from the spray head.

In Fig. 2 a modification is shown in which the rubber ring 10 is considerably wider than in Fig. 1, and has its inner face rounded as at 101) to conform with the curvature of the portion A of the spray head. In the inner face of the ring is likewise provided the annular groove 10a into which .the annular flange A of the spray head engages. In the lower face of ring 10 is an annular recess 10c adapted when the spray head is placed over the drain CD, as in Fig. 1, to set up a vacuum in the ring 10 itself to further assist in holding the spray head in place over the drain D when the water is applied to flush the drain. Owing to the increased width of the ring 10 a portion 10d slightly overlaps the lower face of the spray head and further secures the ring on the head.

In Fig. 3 the ring 20 is somewhat similar to that shown in Fig. 1, and is provided with the substantially straight inner portion 20a having the annular recess 20b for receiving the annular rib A of the spray head. This spray head however is provided with double concave portions A and A adjacent the rim A and on the upper end of the ring 20 is an inwardly extending semi-circular bead 20c adapted to conform with the concavity of the upper concave portion A forming an additional lock for the ring on the spray head.

In Fig. 4 the ring 50 is substantially the same as that shown in Fig. 1 with the exception that the annular recess (1d of Fig. 1) is omitted. When this ring 50 is applied to the spray head as shown in Fig. 5, the resilient rubber will be necmsa.

deformed over the annular rib A of the spray head and the rubber adjacent the rib will be caused to assume a shape substantially similar to the recess shown in Fig. 1, even though such recess is omitted, the inner face of the ring 50 being indented by the rib A as at 50a when applied to the spray head.

In Fig. 6 a further modification of the ring is shown, the ring 60 being substantially similar to that shown in Fig. 4, except that the ring is substantially rectangular in cross-section having parallel inner and outer faces, and having an enlarged exterior head 60a on its lower end. When this ring is applied to the spray head as in Fig. 7 the annular rib A will form an annular depression 60b in the inner face of the ring and the ring will have a double point of contact as in Figs. 1, 3 and 5.

The rings are all made smaller than the diameter of the rib A of the spray head so that they will be stretched over the rib, and the rings can be made in different sizes to fit different sizes of spray heads. I claim:

1. In combination with a spray head having a spray face and having an annular exterior rib adjacent the spray face, a resilient bumper ring of substantially rectangular cross-section stretched around the rib making a tight contact therewith, the ring protruding beyond the spray face; and the inner end of the ring contacting with the spray head adjacent the rib to provide a double frictional contact between the ring and head.

2. In a combination as set-forth in claim 1, said ring having an annular groove in its inner periphery for the reception of the rib.

3. In a combination as set forth in claim 1, said ring having an annular groove in its inner periphery for the reception of the rib, the inner end of the ring having an internal annular bead contacting with the spray head adjacent the rib.

4. In a combination as set forth in claim 1, said ring having a groove in its inner periphery receiving the rib; said ring having an annular groove in its outer face for effecting a tight seal beyond the spray face when contacting with a surface.
