ORGAN-PIPE FOOT.

Application filed September 8, 1923. Serial No. 661,582.

This invention relates to an organ pipe foot of the type comprising a wooden body and a separate soft metal toe cast around one end of the body. Organ pipe feet of this sort are disclosed in my U. S. Patents No. 608,704, dated August 9th, 1898, and No. 844,613, dated February 19th, 1907.

The aim of the invention is to provide an organ pipe foot of this sort having various features of novelty and advantage and, more particularly, to provide an improved construction which is characterized by its simplicity, cheapness and strength. -The arrangement is such that a minimum number of operations are necessary in its manufacture, the amount of soft material employed in. the toe is lessened, and the tee is secured to the wooden body in such manner that it cannot become loose.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts which will. be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the ap pended claims.

In the accompanying drawing, wherein I have shown, for illustrative purposes, two embodiments which the invention may take:

Figure 1 is a side view of the wooden body;

Fig. 2 is a longitudinal central section therethrough with the soft metal toe cast in place thereon; and

Fig. 3 is a view similar to Fig. 2, but shows a slightly different arrangement.

Referring to the drawing in. detail, a denotes the wooden tubular body, and Z) is the soft metal toe cast thereon. One end of the body is provided with a tapering portion 10 preferably of lesser diameter than the main portion of the foot. The outside surface of this portion 10 tapers downwardly in diameter towards its outer end. In the present illustrative disclosure of the invention, the portion 10 is in the form of a truncated cone. Provided, in conjunction with the tapered portion 10, is a groove 12 into which the metal of the toe runs when it is cast onto the portion 10. Thus, there is formed on the toe an internal annular rib 13 within the groove 12. If desired, the tapered portion 10 may have a longitudinally extending notch or key-seat l4, and the toe b may have a key 15 positioned within said seat.

The arrangement shown in Fig. 3 is somewhat similar to that shown in the preceding embodiment, except that the groove 12 is positioned intermediate the ends of the tapering portion 10, and this portion is somewhat curved longitudinally. Also, in F ig. 3, the key-seat and key are omitted, as it has been found that there is little likelihood of the toe working loose when the key is omitted.

With the arrangements described, it will be seen that since the portion 10 is tapered in the same direction as is the toe, the tapered portion 10 may be relatively long, thus presenting a relatively large bearing on which the too will have a very good purchase.

Owing to the interlocking rib 13 and the groove 12, the toe cannot be withdrawn from the body a without mutilating or destroying the parts. Thus, there is provided an extremely strong structure in which the toe cannot be worked loose. The'tapering portion 10 and the groove 12 may be formed in a single operation, thus making for economy in manufacture. Also, the arrangement provides for a saving in the amount of lead employed in, the toe. Owing to the fact that the toe has a large bearing surface on the tapered portion 10, and also because of the rib 13, leakage at the joint between the parts is avoided.

Thus, by the above construction, are accomplished, among others, the objects hereinbefore referred to.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described,

and all statements of the scope of the invention which, as a matter of language, mi ht be said to fall therebetween.

claim as my invention:

1. An organ pipe foot comprising a wooden body having a circular portion provided with an annular groove and tapering down towards its outer end, and a soft metal toe cast on said portion and having an annular rib engaging in said groove.

2. An organ pipe foot comprising a tubular wooden body having at one'end a portion of reduced diameter provided with a groove, and a soft metal toe cast on said port-ion and having an annular rib engaging in said groove, said reduced portion and the surrounding portion of said toe being tapered down in the same direction.

3. An organ pipe foot comprising a tubular Wooden body having at one end a frustaconical portion of reduced diameter and tapering down towards its outer end, a groove at the base of said tapered portion, said tapered portion having a notch, and a soft metal toe cast on said portion and having an annular rib engaging in said groove, and the tongue on said toe engaging in said notch in said seat.
