Description

June 14, 1932. N. B. STONE RESURFAGING TOOL Filed May 20. 1930 Patented June 14, 1932 UNITED STATES NATHANIEL IB. STONE, OF WASHINGTON, DISTRICT OF COLUMBIA RESURFACING TOOL Application led May 20,
This invention relates to a tool designed for resurfacing valve seats of faucets, to insure a true and even seating of the valve washer.
The primary object of the invention is to provide a tool having an adjustable centering member so constructed that when the tool is positioned to resurface a valve seat, the centering member will automatically adjust itself to insure an accurate fit between the centering member and opening in which it is positioned, to hold the tool against lateral movement while in use.
A further object of the invention is to provide a tool of this character, the centering member being held within the body portion by its frictional Contact with the body portion, eliminating the use of adjusting or holding screws.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing:
Figure l is a sectional view through a faucet showing the resurfacing tool as positioned therein.
Figure 2 is a longitudinal sectional view v through the tool.
Figure 3 is an elevational view of the centering member, the bit being shown in section.
Figure 4 is an end elevational View of the tool.
Figure 5 is a sectional view taken on line 5 5 of Figure 3.
Figure 6 is an end elevational View illustrating a modified form of the invention.
Figure 7 is a transverse sectional view through the modified form of centering member.
Referring to the drawing in detail, the tool embodies a tubular body portion 5, the same 1930. Serial No. 454,073.
being provided with a handle or grip 6, disposed at one end thereof.
The reference character 7 designates the centering member which is formed of a length of metal bent upon itself to provide yieldable leg sections 8, the forward end of the centering member being tapered as at 9 so that it will fit into various sized valve seat openings, to hold the tool against lateral movement while in use.
As shown, these leg members are substantially long so that they will extend an appreciable distance within the body portion to grip the body portion. The bit which is indicated by the reference character l0, is formed with a reduced portion to be crowded in one .end of the body portion. Lateral cut out portions are also formed in the bit to accommodate the leg members 8 to permit of movement of the centering member within the body portion.
Lugs 11 are formed on the leg members 8 and are disposed opposite to each other, which lugs provide seats for the ends of the coiled spring l2 that is shown as exerting a pressure against the inner surfaces of the leg members, to force the leg members outwardly into close engagement with the body portion. Disposed at points intermediate the ends of the leg members, are lugs ll that acts as stops to prevent the centering member from being pulled outwardly too far when it is being moved to its normal position.
Slidably mounted on the body portion 5 is a tapered sleeve 13 which is adapted to seat itself in the valve stem opening, to further hold the body portion against lateral movement while in use.
In order that the centering member will `be restricted in its movement within the body portion, a coiled spring 14 is provided, the spring being held within the body portion and slightly compressed between one end of the plug l5 and inner end of the centering member 7.
In the form of the invention as shown by Figures 6 and 7 of the drawing, the centering member embodies three legs indicated by the reference character 16, which legs taper towards the outer end of the centering member where they merge into the rounded eX- ber extending beyond the bit and engaging tremity 17. 'Ihe bit 18, used with this form the bit to prevent rotary movement of the of the invention, is provided with three cut bi out portions extending from the edge theret Within the tubular body portion. In testimony that I claim the foregoing of, which cut out portions accommodate the as my own, I have hereto afiixed my signalegs 16, the portions of the bits adjacent to ture.
the legs 16 being formed into cutting blades 19 that are inclined towards the direction in which the tool is rotated, to cut the valve seat.
A wide spring member 2O is positioned between the legs 16, and act to urge the legs laterally to set up a binding action between the legs and body portion in which the centering member is positioned.
In the use of the tool, the tool is positioned so that the centering member thereof will extend into the valve opening adjacent to the valve seat, in a manner as shown by Figure 1, whereupon the tool is rotated, cutting the valve seat to resurface the same.
I claim:
1. A valve resurfacing tool, comprising a hollow body portion, a centering member comprising yieldable leg members, extended into the body portion, means for forcing the leg members laterally into close engagement with the body portion, a bit having cut out portions to receive the leg members, and a tapered centering sleeve on the body portion.
2. A valve resurfacing tool, comprising a tubular body portion, a centering member embodying a length of metal bent upon itself to provide yieldable leg members and a tapered extremity, said centering member being adjustably held in one end of the body portion, and a bit mounted at one end of the body portieri adjacent to the centering member.
A valve resurfacing tool, comprising a tubular body portion, a centering member embodying a length of metal bent upon itself to provide leg members, a coiled spring disposed between the leg members to normally urge the leg members laterally to hold the centering member in position by frictional contact with the body portion, a bit secured in one end of the body portion and adapted to rest against the valve seat to resurface the valve seat when the body portion is rotated, and a spring within the body portion and engaging the centering member for normally urging the centering member longitudinally of the'body portion.
4f. A valve resurfacing tool including a tubular body portion, a bit having a reduced end deiining a shoulder, the reduced end being of a diameter to closely fit within the body portion, said shoulder adapted to engage one end of the body portion, a centering member extending into the body portion and including spaced leg members, yieldable means engaging the leg members to urge the leg members laterally into close engagement with the body portion, said centering mem- NATI-IANIEL B.
