Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, DANIEL N. DUNZACK, of Saleni, in the county of Essex and State of Massachusetts, have invented a new and Improved Lever for Turning Faucets in Pipes, so that They May be Conveniently Operated; and I do hereby declare that the following is a full and exact description.

My invention consists in a lever B, as seen at Figure l, and is forined in two parts thatit may be lengthened or shortened, as the ease inay require, and is fastened together with clasps, Fig. l, and is kept elevated by a screw K, which passes through one of the parts into the other and is behind weight G, and near its top and must be turned back before the parts can be separated.

At the top of lever B, is a hollow transverse head A, Fig. l. At the lower end of lever B, is secured a beveled cog wheel P, which intersects with a larger beveled cog wheel F, there is a forked coupling I, Fig. 4, the square shank of which passes up through cog F. The forks connect cog F with the handle of faucet L, which passes through pipe N, Fig. l. Then lever B, is turned to the right or left side of pipe N, the cogs P, and F, turn the 'faucet L, and let the water on or off freni the small pipe N, Fig. l.

In the hollow of head A, Fig. 1, there is a slide O, Fig. 2, which tits loosely in said head A, and when lever B, is canted from its center, the slide C, Fig. 2, will pass down tothe lowest end of said head A.

There is a toggle Y, Fig. 3, which passes through slide O, which has a notch and a hole in it for that purpose. Toggle Y, has a base which corresponds with the notch cut in slide C. Head A, is provided with two ianges T, T, at the top, upon the inside. Slide C, passes under the flanges, T, T, the top part of toggle Y, passes through slide O, up between the two flanges T, T, sufficiently far enough to adinit a string or wire being attached to it, and slides on the bottoni of the hollow in head A. There is a pin I at each end of head A, which prevents slide C, freni dropping out of the ends of head A. There is a weight G, the use of which will presently be explained.

The inode of operation is as follows, when the water is to be let into the sniall pipe 26,975, dated January 31, 1860.

from the inain one X, lever B, being canted to the right side and slide O, being at its lower end, one end of the wire is passed through a pulley secured directly over the faucet in the small pipe and fastened to the outer end of toggle Y, which is in the head of A, Fig. l. The other end of the string may be carried to any part of the house. Then the wire is pulled, the upper end of toggle Y, will be canted toward the wire, consequently its base, which rest on the bottoin of the hollow of head A, will lift one end of slide O, and cause it to pinch against the two flanges T, T, which will prevent its slipping toward the wire, at the same time shaft G, will cause lever B, to move in a. prescribed circle, and in this inanner lever B, is drawn up by the wire or string beyond its center, and that part of lever B, whichv has the weight attached to it, having been previously sutliciently elevated, to overconie the power required to turn the faucet, weight G, will carry lever B, down upon the opposite side from which it started, and when the wire is slacked, slide O, will pass down to the lower end of head A, and is again ready for drawing the lever to the other side. In this way the faucet in the cellar may be turned to let the water into the small pipe, or let it out through the waste which will prevent its freezing, in the pipe, or having the water injured by its long standing in the lead, with as inuch facility as it can by the faucet in the sink, without the necessity of going into the cellar in order to turn it. Lever B, is fastened to the niain pipe X with a clasp V, which is tightened with a wedge Z that it may be turned to any angle that niay be required to connect it with the handles of the sinall pipes, substantially as herein shown and described.

I do not clailn either of the devices separately considered` but lVhat I claiin and desire to secure by Letters Patent is The arrangement and combination of lthe several parts when arranged and combined as herein described, for the purposes set forth.
