PLUMBER/S SPUD.

Application filed August 29, 1914.

To all whom it concern.

Be it known that I, ARTHUR H. MOORE, a citizen of the United States, residing in the city of Eric geport, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Plumbers Spuds, of which the following is a full, clear, and exact description.

This invention relates to a plumbers spud such as commonly used for connecting with a water" closet bowl the usual supply or flushing pipe leading from the flushing tank. The improved spud is however applicable to other purposes.

The primary object of the invention is to provide a spud which may be readily and economically manufactured from sheet metal, but which, in spite of the thinness'of the material used, is interchangeable with point when it is the ordinary thick, heavy spuds of cast metal. in other words, the comparatively thin sheet metal spud which I have devised can be used with the standard sizes of bowls and fittings without the necessity of modifying the construction of such bowls and fittings in any respect, and as the improved spud may be much more cheaply produced than the ordinary cast spud, the cost of in stalling the bowl or other fixture is considerably reduced.

Other objects of the invention are to provide a sheet metal spud wherein the attachng lugs are reinforced in a novel manner, and certain special provision is made for arresting the supply pipe at the proper pushed into the spud in mounting the fixture.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

ln the accompanying drawing, Figure 1 is a sectional view of a coupling between a water closet bowl and flushing pipe, embodying my improvements, Fig. 2, is a side elevation on a somewhat smaller scale of the spud with. the gasket and nut mounted thereon, Fig. 3 is a longitudinal section of the spud, Fig. l is an end elevation of the same, Fig. is a longitudinal section of a spud of somewhat modified construction, and Fig. 6 is a side elevation of the coupling nut detached.

Referring to the drawing, and particularly to Fig. 1, 11 indicates the inlet at the Specification of Letters Patent.

rear of a water closet bowl, which inlet is of the usual shouldered circular form, having the customary recesses or cut away portions (not shown) for interlocking with the attaching lugs of the spud. The spud 12 consists of a cylindrical body or sleeve of an exterior diameter corresponding approximately to the interior diameter of the inlet 11. This sleeve is provided at one end with lugs 13 cooperating with a shoulder 13 on the bowl. When in assembled position part of the spud is located within the inlet 11 and part of it projects rearwardly out of said inlet. It is permanently secured in place by means of a nut 14:, engaging exterior screw threads 15, with which the cylindrical wall of the spud is provided. A gasket 16 is fitted over the outer end of the spud and placed against the outer surface of the bowl inlet, after which the nut 14 is placed on the spud and screwed up thereon in order to press the gasket 16 tightly against the rear surface of the bowl inlet, whereby the lugs 13 are drawn into tight engagement with their seat.

The spud 12 is constructed of sheet metal and is quite thin as compared to the ordinary cast metal spud. The lugs 13 are bent up integrally from the spud body and in order to reinforce the same, and the adjacent portion of the spud proper, and to prevent the lugs from being readily bent out of place or distorted, I provide each lug with a longitudinal reinforcing rib 13 I prefer to form this reinforcing rib by indentation of the metal, which is indented at the rear surface of each lug, as shown at 13, and by preference also at the exterior surface of the adjacent portion of the spud proper. In this manner a longitudinal groove or cor rugation is formed on the outer surface of the spud proper, which merges into a longi tudinal groove or corrugation on the surface of the corresponding lug. This construction produces in efiect a longitudinal corrugation in each lug and in the adjacent part of the spud proper, whereby the strength of the device is considerably increased.

At the rear end the edge of the body or sleeve of the spud is turned in slightly to i form an annular flange 17, as shown in Fig. 3. This flange defines an opening which is of less diameter than the internal diameter of the major portion of the spud. This opening is intended to fit snugly a supply 1 able stops may be provided on the spud to limit this inward movement of the supply pipe in assembling the fixture and to arrest v the supply pipe in the desired position. In

the form shown the stops are indicated at 1.9, and they are constituted by inwardly di rected projections on the cylindrical wall of the spud. These projections are preferably punched up integrally from the spud by displacing the metal of said wall inwardly by means of a suitable punch or similar tool, which in forming a depression 20 on the outer surface of the wall creates a somewhat larger projection on the inner surface of the spud wall. l/Vhen the supply pipe 18 is forced into the spud its forward edge will abut the propections 19 and the pipe will thereby be arrested in the proper position. In the particular form shown there are four of the projections 19 spaced equidistantly around the circumference of the spud, but the number of such projections and their particular arrangement may be varied as desired to meetthe existing conditions.

Owing to the fact that the exterior diameter of the supply pipe is at least as small as the interior diameter of the bearing formed by the flange 17, the stop projections must obviously extend to a greater distance into the interior of the spud than does said flange, in order that said projections may form substantial abutments for the inner edge of the supply pipe.

In the form shown in Fig. 5 the outer edge of the spud is not only turned in to reduce the diameter of the spud at that point, but is also turned in a reverse direction to form a fairly extensive bearing 21 of less diameter than the internal diameter of the main part of the spud.

Without limiting myself to the precise construction shown I claim:

1. The combination with a water closet bowl having an inlet, of a spud comprising a sleeve of sheet metal fitting within said inlet, means to secure said sleeve in said inlet, a flange on the outer end portion of said sleeve, extending inwardly relatively to the sleeveto reduce the effective internal diameter thereof at that point, and a supply pipe extending some distance into said sleeve through the outer end portion thereof, and directly engaging and having a bearing in the inner bearing surface of said flange; substantially as described.

A. plumbers spud, comprising a sheet metal sleeve having laterally extending lugs, and provided with an inwardly turned flange, reducing the internal diameter of the sleeve at one point and having an 1nterior bearing for the supply pipe, said lugs reinforced by corrugation of the metal; substantially as described.

3. A. plumbers spud, comprising a sheet metal sleeve having laterally extending lugs, reinforced by longitudinal corrugations, said corrugations being continued or extended into that portion of the spud proper adjacent each lug; substantially as described.

at. A plumbers spud, comprising a sheet metal sleeve, an outturned part on one end of said sleeve to engage the wall of the supply inlet, an inwardly turned flange on said sleeve at the opposite end to serve as a bearing for a supply pipe inserted into said sleeve, and internal stops for the V supply pipe, located on the sleeve wall intermediate said outturned part and said inturned flange, said stops extending inward into the sleeve to a greater distance than said flange, and being formed by forcing portions of the sleeve wall inward past the bearing surface of said flange; substantially as described.

The combination with a water closet bowl having an inlet, of a spud comprising a sleeve of sheet metal fitted within said inlet, means to secure said sleeve in said inlet, a flange on the outer end portion of said sleeve extending inwardly relative to the sleeve to reduce the effective internal diameter thereof at that point, a supply pipe ex tending some distance into said sleeve through the outer end portion thereof, and having a bearing in said flange, and stop means integral with the sleeve and cooperating with the inner end of said supply pipe; substantially as described.

In witness whereof, I. have hereunto set my hand on the Z Lth day of August, 1914:.
