My invention relates to new and useful improvements in valve seating tools; and it consists in the construction and combination of the parts as set forth in the accompanying drawings and set forth in the following specification.
Th object of my invention is to provide a valve seating tool for cocks, faucets, valves, and the like, and to provide means whereby 10 the valve seat can be recut when the same becomes worn or incapacitated in any manner, the same can be readily repaired without necessitating the disconnection of the casing from the pipes to which it is secured.
In the accompanying drawings, which illustrate my invention, Fig. 1 is a sectional view of the valve seating tool showing my invention in cross section.
Fig. 2 is a full view of the valve seating tool constructed as in Fig. 1, showing a partial view of the stem, also the cutting tool in reversed position, using the flat side of the said cutting tool as an auxiliary means coacting with an abrasive disc, used to polish the seat when renewed or recut.
Fig. 3 is a view, partially in elevation and partially in longitudinal central section, of the cap Fig. 1 showin construction of same when slidably and rotatably mounted on the stem.
Fig. 4 is a top view looking in the direction of the arrows X-X in Fig. 1, showing the collar 6 provided on its outer face with raised portion, which is bisected by a series of grooves, providing means to partially reduce friction on the lock-nut when it is screwed upon the stem against this collar.
Fig. 5 is a bottom view of a cutting tool, showing cutting edges and lips, also means U into which a suitable tool or handle may be inserted in screwing the same on or off the stem.
6 is a view, partially in elevation and partially in longitudinal cross section of a cutting tool, showing a dove-tailed annular groove in the top side of the cutting tool.
Fig. 7 is a top view of the collar section showing this collar bisected by a series of grooves on its outer face.
Fig. 8 is a bottom view, of a cutting tool I,
with four cutting edges and lips.
Fig. 9 is a top view of Fig. 6, showing the dove-tailed annular groove.
Fig. 10 is a bottom view of a modification of the cutting tool.
Fig. 11 is a bottom view of the lock nut showing same provided on this face with raised portion bisected by a series of grooves.
Fig. 12 is a view, partially in elevation and partially in longitudinal cross section showing the cap 11 provided with a shoulder portion for a wrench or other suitable tool and also provided with means to accommodate the handle 5. This view also shows an auxiliary unit screwed into the cap 11 and also provided with a shoulder portion for a wrench or other suitable tool, and having an externally threaded portion adapted to fit internally threaded casings of faucet-s, valves, and the like.
Fig. 13 is a full side view of the cap 11, constructed as in Figure 1, showing a shoulder portion at its top to take a wrench or other suitable tool.
Fig. 14 is a view, partially in elevation and partially in longitudinal central section of another auxiliary unit having an internally threaded portion adapted to provide means for casings of the larger types of faucets, valves and the like, having externally threaded portions.
1 refers to the lever, handle or wheel, which is mounted on the stem 2 which is screwthreaded at one end in the usual manner, said screw-threaded portion terminating in a smooth body portion 15 of the stem. At this end the stem is reduced in diameter forming a shoulder and this stem portion 16 is threaded to take the threaded cutting tool 17 The lock nut 3 is provided with a threaded hole or bore 2 to take the stem, it is also provided with raised portion 24: 24 24: 24, which is bisected by a series of grooves 23232823, on its under face, providing means to partially reduce friction when the lock-nut is screwed upon the stem and brought into contact with the collar 6. The handle 4 of the lock-nut may be integral with the lock-nut, or separate and inserted into opening provided therein as is shown in Figs. 2 and 12. This opening for said handle is designated as 5. Numeral 6 refers to the collar that is fixedly mounted on the shoulder sleeve 9 by the pin 7. Numeral 8 refers to the space between the collar 6 and the cap 11,
its purpose ill be more fully explained. Numeral 9 refers to a sleeve having a shoulder portion, and internally threaded to take the threaded stem 2. The wearing ring 10 is mounted on the shoulder sleeve 9. The cap 11 is mounted on the shoulder sleeve, this cap having a series of threaded sections 12, 13, and i l, varying in diameter to take the various sizes of faucets, valves and the like as the case may be. The cutting tool 17 has a threaded hole or bore 16 to take the thread ed stem, and it also has a plurality of cut ting edges 19,19, 19, 1, and lips 18,18,18,18, and it i also provided with an annular dovetailed recess 22 providing means to hold abrasive materials in polishing the recut seat. The screw 20 provides means to hold abrasive disc 21 against the flat side of the cutting tool, when this method is used. Numeral 25 in Fig. 12 refers to shoulder portion on the cap 11, providing means to take a wrench or other suitable tools. Numeral 26 refers to shoulder portion on the auxiliary units, these units are provided with a threaded portion let to screw into threaded portion 1a of the cap. These auxiliary units are also provided with integral screw portion 27 and 28 adapted to take the larger sized internal and externally threaded faucet and the like. 29 refers to shoulder portion on a modified form of cap 11 adapted to take wrench or other suitable tool.
A special feature of the aforesaid space, is the provision which enables the tool-stem after being brought into contact with the valve seat to be slightly backed away from the seat, to be again brought in contact with the seat due to this slight space between the collar and the cap. This slight up and down movement provided for by this space takes the stress off the cutting edges and lips on the cutter. The tool-stem being locked in the shouldered sleeve, being rotated taking oif the high spots first, after the seat has been partly formed, the cutter can be brought into contact with the valve seat and locked eliminating the slight backing away movement in the first adjustment of the cutter with the seat. It will be understood however that this space is not absolutely necessary in the operation of the tool.
The grooves 23 and the raised portions 2& are provided on the lock nut and collar to break the continuity of the surfaces and thus reduce the friction between the two acting surfaces.
In practice, the valve seating tool being screwed on the faucet or valve casing, the tool stem with its cutter is screwed down against the valve seat to be recut or renewed, the tool stem is locked in this position by the lock nut, and the handle on the tool stem rotated until the cutter turns freely above the valve seat, if it be necessary to remove still more metal from the seat, the operator holds the handle mounted in the sleeve and turns the stem slightly downwards, again rotates the handle, repeats the operation until desired results are obtained. The valve seating tool is then removed from the faucet or valve.
What I claim as new, and desire to secure by Letters Patent, is
l. The combination, substantially as before set forth, of a threaded stem provided with an internally threaded sleeve, said sleeve having a should r portion thereon, adjacent this shoulder portion a wearing ring, cap rotatably mounted on sleeve, collar fixed to said sleeve portion adapted to hold sleeve in cap, look-nut on threaded stem providing means to lock stem in the sleeve, cutters mounted on st m, cutters provided with a series of cutting edges and lips, and having an annular recess on its upper face, the cap having a series of stepped threaded portions, and auxiliary units adapted to fit said cap.
2. The combination of a threaded stem provided with an internally threaded sleeve, said sleeve having a shoulder portion thereon, a cap rotatably mounted on the sleeve, a collar fixedly mounted on said sleeve portion adapted to hold sleeve in cap, a handle mounted in said collar adapted to hold the sleeve in the cap from rotating, a lock-nut threadedly engaging the tool-stem providing means to lock tool-stem in the sleeve, cutter mounted on stem, cutter provided with a series of cutting edges and lips, and a cap having a series of stepped threaded portions adapted to engage various sizes of casings of faucets and valves.
3. The combination of a threaded stem provided with an internally threaded sleeve, said sleeve having a shoulder portion thereon, a cap rotatably mounted on the sleeve, a collar fixedly mounted on said sleeve portion adapted to hold sleeve in cap, a cutter mounted on stem, the cutter provided with a cutting edge and lip, and a cap having a threaded portion adapted to engage various sizes of casings of faucets and valves.
