SPRING-(COMPRESSION FAUOET.

' srncrrrca'rron forming part of Letters Patent No. 286,365, dated October 9, 1883. Application fileaaanuaryao, 1881:. (No model.)

To all whom it may concern;

Be it known that I, JosErn ZANE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts', have invented certain new and useful Improvements in the-Manufacture of Spring- Compression Faucets; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawings, forming a part of this specification.

In the manufacture of self-closing springfaucets which employ the Jenkins invention,

patented June 27, 1865, of a steep-pitched screw or cam with a twisting handle, or of spring-compression faucets which employ a slowenpitched screw and twisting handle,

- both of which sorts of faucet-s are spring-compression faucets, some difficulties have always existed in obtaining a construction which shall be at once economical and have the property of protecting the cams or screws from,

the best construction'for the slow movement has been the crown-snail form of cams, and for the quick movement the quick-screw, usually of three or four threads. In this invention I propose to employ the crown snail movement, as in the Roach patent of September 6, 1868, for both the quick and slow inclines. In this invention I make the T=han die with a large central bulb, containing a recess deep enough to completely or very nearly cover the cams both of the neck and handle when the valve is open, and in the depth of this recess, at or near the upper part of the handle, the downwardly-projecting cams, counterparts of those which form the crown-snail on top of the neck of the faucet are located. These arepreferably cast in situ, but may be made separately and soldered in, or may be out. The bulb must be large enough and the recess deep enough to practically cover the cams on the neck of the faucet, which form the crown-snail, when the handle is so turned as .to give the valve its greatest lift.

The sides of the recess in the bulb of the ham dle are more sharply tapered than usual in castings, so that the pattern may draw, and

the casting is done in a two-part mold divided stemway is also made at the other or up per extremity of the neck of the cap. The crown-snail also, which terminates the neck of the faucet upward, is completely formed in casting, and requires no finish. In case the slow incline is employed, it is desirable to have stops to check the revolution'of the handle, so that it will not jump the cams while in the employment of the quick screw or cams. The compression of the spring has hitherto been sufii cient as a stop for all practical purposes. I make the stops, as well as the cams, by casting. side, radially, of the crown-snail, and are little projecting blocks at the highest part of the inclines on the neck and at the lowest part of the inclines in the handle, one or both sets of them projecting toward the other. I prefer to have the stops on the neck flush with the upper surface of the crownsnail for constructive reasons. By this form of construction I amenabled to save about ten per cent,

or more, of the cost of a faucet, and make it just as good and not inferior in appearance.

The bearing-surfaces, also, having their natu- They are on the outthe cap and handle parts of the same faucet as.

Fig. 8 is avertical section of the cap and handle parts of the same faucet as they would be valve closed. Fig. 9 is a perspective of the cap of the same faucet. Fig. 10 is a perspective of the handle of the same faucet, showing the interior. Fig. 11 is a top plan of the cap and neck of the same faucet. Fig. 12 is a bot tom plan of the handle of the same-faucet. Fig. 13 is a vertical section of a rough casting of the cap of Figs. 1, 2, 3, 5, showing the cast recesses at top and bottom;

I11 the drawings, A is the handle. It is made with a very considerable enlargement, B, at theplace where it engages with the neck of the cap. WVithin this. enlargement is a recess, O. The handle is bored through this recess for the valve-stem, as seen at D, and around this way for the valve-stem are dis posed, at the deepest part of the recess, cams E, substantially of a spiral cut. The recess 0 is deep enoughv to extend so far below the cams or crown-snail on the neck of the faucet as to completely cover them at the highest lift of the handle, and asthe swell. in which the recess is located is made of globular form, and there is no shoulder on the neck of the faucet, there will be no place for the'insertion of a prop or chip to hold upthe handle, and so let the faucet leak, whether it be desired to insert the prop or chip under the handle in the lower part of the interval between the cams K, or between a shoulder on the handle and a shoulder on the neck, as is frequently done. Unless the cams are without the angle of reposesay steeper than about one in four-the faucet will not be a self-closer, and in such. case it will be advisable to provide stops to check the rotation of the handle. These stops are small projections F at the lowest point of the inclined cams of the handle.

The interior of. the recess and the cams and stops may be left as they come from the sand, for castings can now be made smooth enough for this work without finish other than brush.- ing, and the cams will wear better with their natural skin than if this be removed. The handle is cast-in a two-part mold which separates transversely to the axis of the recess, and thus is in a proper position to draw.

- G is the cap of the faucet. It has at its lower end a shouldered screw-neck, H, to unite it with the body of the faucet, and there is a recess, J, at the center of thislower part, for the reception of the stem-packing. Above 7 the shoulder the cap tapers upward into a neck,

called in these faucets a crown-snail]? of which'the cams in thehandle are counterparts. In case the stops are. desired, they are placed as shown at L, so as to engage with the stops F of the handle at the proper time in the rotation of the handle and prevent the over- I This ,cap is cast in atwo-part mold, with the parting transverse to the axis of the cap, as shown by the dotted line a: a, and there is a recess formed at the upper end of the cap, as shown at M, for

part of the valve-stem way. All the finish that this cap requires is to'be turned or milled on the outside, to be bored for the valve-stem,

and to have the screw out which unites it to the body of the faucet. I cast the recesses in the cap as deep as they can conveniently be cast without coring, which would be too. expensive, and the cams come smooth enough for this kind of work. This construction is intended to be employed inthat class of faucets in which a spring is employed to drive the valve to its seat and the cams to lift the valve from the seat, in which the rotation of the handle does all the work of lifting the valve and the spring 1 does all the work of driving and holding the valve against the water pressure. Fig. 7 shows in section such a faucethaving the quick movement or steep cams essential to a selfcloser, and Fig. 1 shows such a faucet having the slow movement. They both are springcompression faucets. In such faucets the valve-stem passes through the axis of the cap and through the handle, and is confined to the handle by a washer or' annulus, against which the handle lifts in its rise when rotatedover the cams. This construction is shown in the Roach It will be seen. that what is now shown relates to details of construction, whereby abetter article and a cheaper article can be made better because more durable, cheaper because requiring less material to start with and less labor and wearof tools to finish and complete and these results are reached by change of form of the working and other adj acentparts,
