SCUPPER Filed Dec. 26, 1929 INVENTOR \iPMead ATTORNEY Patented Apr. 14, 1931 UNITED STATES STUART P. MEAID, 0F TACOMA, WASHINGTON SGUPPER Application filed December 26, 1929. Serial No. 416,672.

This invention relates to improvements in scuppers such as used inconnection with all types of ships, for example, war vessels, yachts, houseboats, barges, etc., and it consists of the constructions, combinations and arrangements herein described and claimed.

An object of the invention is to provide a scupper made of yieldable material, for example, molded, reinforced rubber, which, by virtue of the combined qualities of flexibility and toughness, enables the production of such a device at a low cost as well as a more eflicient maintenance thereof inasmuch as it .will withstand blows with less likelihood of damage either to itself or to the object imparting the blow than would be the case if the scupper were made of metal.

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawing, in which Figure l is a perspective view illustrating the installation of the improved scupper upon the side plates of a. ship.

Fig. 2 is a central longitudinal section illustrating a back check valve used in conjunction with the scupper.

Fig. 3 is a somewhat enlarged sectional view of the scupper particularly illustrating the reinforcement of the rubber.

Fig. 4. is a detail cross-section taken substantially on the line 44 of Fig. 1.

Fig. 5 is an elevation of a form of the scupper modified to over-reach an armor belt on the ship.

Fig. 6 is. an elevation of a modified form of the scupper assuming the shape of an elbow.

As is commonly known, especially among persons having to do with the management of ships, a scupper is a device or an arrangement of some sort for the purpose of an overboard discharge of water. Scuppers made .of metal are known and are in use and by virtue of their outstanding position on the side of the ship are subject to being struck and damaged.

In addition to being heavy, such scuppers .are costly to repair, and since these devices Hare sometim s truck with such f rce as to destroy them beyond repair, an ever higher cost is entailed by virtue of the necessity of a complete replacement.

Other disadvantages of metallic scuppers are that a trail of rust will soon appear at the sides and especially below the place of connection with the plates of the ship as well as the possibility of setting up a galvanic action. The unsightliness of streaks of rust, especially on war vessels having a project.- in armor belt is apparent enough, and in any case is objectionable because of the dis coloration of the side of the ship.

All of theforegoing objections are obviated entirely by making the scupper 1 of amaterial such as rubber. The scupper cornprises a spout 2 and a surrounding flange 3. This flange is continuous and the upper part of it bridges the opening 4, at which the scupper has communication with the outlet side of a casing 5 (Fig. 2) containing a back check valve 6. The inlet side of this casing has connection with a soil pipe 7 in the present instance, but obviously the connection of the scupper may be with anything else.

A rectangular metallic annulus 8 is made to bear against the outside of the flange 3 not only to insure pressing the flange against the side plates 9 of the ship, but also to furnish a sufficiently stout foundation or bearing for the heads of the securing means 10. The securing means may comprise screws or bolts, the preference being optional with the person making the installation.

A reinforcement 11 imparts more strength and toughness to the scupper 1 than the rubber or other yielding material ofwhich it is made possesses. This reinforcement may comprise a wire or cloth insert, a preferred disposition of the reinforcing strands being longitudinally of the spout 2, as clearly. designated in Fig, 3, and as also suggested in Fig; 4:. These strands may extend into the flange 3,in any appropriate way, but in merging the spout strands with the flange strands of the reinforcement, consideration must be. given to the possibility of the spout being struck in almost any lateral direction with a on q blin e er to a greater 9r lesser ex ent Assuming thespout to bestruck sidewise,
