IMPROVEMENT IN SAP-SPOUT.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, R. F. Lrvmmons, of Starksboro, in the county of Addison, and State of Vermont,-have invented a. new and improved Sap-Spout; and I do hereby declare that the following is a 'full, clear, and exact description thereof, which will enable others skilled in the art to make and use the some, reference being bad to the accompanying drawings, forming part of this specifieatiom.

Figure 1 is a section, through the line a a, fig. 2, showing the spout when in thetree.

Figure 2. is a top view of the spout.

Similar letters of reference indicate corresponding parts.

This invention consists of a metallic sop-spout, of such a form that many important adventsges are secured over the common wooden spout, as heretofore used, which advantages will he hereinafter fully explained.

This sap-spout is made of metal, and consists. of a spout, A, of any proper length, attached and forming a part of the head D. This head is perforated with a hole, 7;, for the sap to .pass through into the spout A, and thence into the bucket or tub. This head is slightly bevelled on its exterior, as shown at a, and is formed with a conceve surface on that part that faces the hole or tap in the tree, and the said bevelled exterior and the con cavity form a sharp edge, a, which has an important function, and will be hereinafter explained. From the central part of the said concavity projects the screw S, for holding the spout firmly to the tree B, whereby the head D covers the chamber G, which is made in the tree, and the edge a, pressing firmly against the hark,,prevents leakage. The chamber 0 is made by the'ordinary topping-bit, and all that is necessary to sttnchmy metallic spout is to place the screw in the centre of the hole or chamber made in the tree, and turn it till the edges a press firmly against the bark aroundthe hole or chamber, and the bucket or pail hung thereon, the spout being provided with a. projection, E, to retain the bucket in its place. Thesap flows from the walls of the chamber 0, and, flowing through the hole It, is carried by the spout A, and thence falls into the bucket. The spout can be constructed of any desired metal, thoughcast iron is perhaps the cheapest, and, if made of this metal, can be furnished very cheaply; This form of a sap-spout admits of the use of difi'erent-sizedtsppin g hits, but is designed particularly to allow the use of a small hole inthe tree, thereby to lessen the injury to the same, as, from repeated experiments it has been clearly proved that there is no,appreciable difl erence in the quantity of sap discharged from a large or small hole. This spout surrounds the exterior of the chumbenC,

instead of partially plugging the interior of the same, which latter materially lessens the flow of sap, and is the only method practicable with the wooden spouts as now used. The head D, by means of the edge a, perfectly covers the hole in the tree, protecting it from the drying client of the wind or sun, while the chamber G is left free and clear, allowing the sap to fiow from all-ports of it, and by hanging the tub or bucket upon the spoof,

the expense and injury to the tree, of spike and nails, are avoided.

I claim as new, and desire to secure by Letters Patent- As a new article of manufacture, a cast-metal sap-spout, constructed as described, consisting of the spout A, having the head D perforated at h, and provided upon its end with the concave surface, in the centre of which the screw S is secured, the exterior surface of said head bevelled at a to form the edge a, and having upon its'upper side the projection IQ, as herein shown and described.
