April 30, 1935. J. R. LAKE FAUCET RECONDITION INGTOQL Filed June 6, 1954 Patented Apr. 30, 1935' f 9 5," f moons: RECONDITIONIlVG root 7 Jesse Lake; Detroit, Mich.- I I Application une 6, 1934,.Serial No. 729,178 1 4 Claims. (01. 590 125) f It is a general known fact that faucets broadly speaking, are susceptible more'or' less to leakage, or continual dripping'when they are supposed to be closed and completely stopping the flow of liquid therethrough. Customarilywhen the valve seat of the'faucet is badly worn or otherwise deteriorated, even by turning the valve stem of the faucet as tightly a s'possible by the operator thereof, a leak can not be avoided due to the imperfect engagement of the stemwith the seat thus indicated. 7 It is further known that there have been various attempts tocorrect this difficulty and apparently little or no progress has been madeinthisconnection. g This invention seeks to 'anddoes positively overcome this difiiculty byp'ro'vidi'ng a small and;

compact tool with a series of cutters formed thereon so that by the simple operation of removing the stem from the faucet so affected and by inserting the tool directly'into the faucetwhere the stem has been removed, and withthe aid of the bonnet of the faucet, the tool is rotated gently" by the operator, thereby recutting the valve seat.

'1 The tool is then removed and the faucet reas-- sembled for use. I 7

Another advantage of the invention is that the same provides a feature whereby it may be readily adjusted to practically any size of. faucet as the valve seat therein is usually of a standardized dimension and proportion. I 7,

The invention possesses further" advantages, which will become readily apparent during the course of the following detailed description, illustrated throughout the accompanying drawing, and more fully pointed out in the appended claims.

With reference to the drawing:

Figure 1 is a longitudinal section substantially twice size, of a typical faucet and showing the invention likewise enlarged and normally in the act of operation. 7

Figure 2 is an elevation of the complete invention, drawn to substantially full size.

Figure 3 is an enlarged section taken directly upon line 3-3 of Figure 2.

Figure 4 is an enlarged bottom structure shown in Figure 2.

In the following description the invention proper will be distinguished by the customary reference numerals, while the various elements of the faucet will be designated by orderly letters of the alphabet.

The invention comprises elongated tubular shell I having square shank 2 formed upon the upper View of the nently remain within said slot.

end thereof, and saidshank being adapted to detachably engage handle portion 3 as indicated. Stem' i is provided and is detachably positioned within shell' I as clearly revealedin Figure 1. The upper end portion of said-stem being provided with externalthreads 5 so as to accommodate nut 5 as indicated. The lower end portion of shell I is arranged so-as to form cutting-jaws I which are adapted to accu'rately conform to" valve seat'A- of the faucetiyand'in Figure f1 it is seen that cutters 1 are preferably spaced at degrees- The lower extremity of the shell is constructed toform a cutter pilot. I The lower endof stem 4 is arranged so as t form conically disposed expander 8, and elongated slots 9"with in shell I render jaws (susceptible to expansion o-r closing by virtue of expander 8' of stem 4 for purpose of adjusting said jaws so asto be adapted to properly engage the valve seat upon which the cutting operation is to be performed.'

An important. feature is the method employed for aiding jaws I in the closing movement thereof for adjusting them from a larger proportion to a smaller proportion, and this method consisting of circumferentially formed recess II] upon shell,

I where indicated and spring II coiled within said of same, comprises lug I2 which is formed integral with said stem and is adapted to slidably engage one of slots 9 within shell I and perma- Sleeve I3 is provided and has funnel-shaped lower end I4 which is adapted to engage opening B within bonnet C of the faucet. It is also observed that a plurality of spaced apart grooves I5 are provided where shown upon shell I and in circumferential formation, and any one of said grooves being adapted to detachably receive spring I6. The purpose of sleeve I3, grooves I5 and spring IE will be presently explained.

The details of construction of the invention having been completely set forth during the course of the severalpreceding paragraphs, the operation and advantage. thereof follows:---

The faucet'D is dismantled by removing bonnet C with the. original stem (not shown), and

Sleeve I3 being slidably positioned upon shell v The tool as indicated is then inserted within fan-- cet D and jaws 1 are adjusted to properly conform to yalve seat .A bymean'skof ;nut 6. Of course it is understood that bonnet C has been inserted upon threads E of faucet D; In vieweof spring 5 retaining sleeve l3 with'funnel-shaped end l4 thereof being taut with opening Bo f said bonnet handle portion 3 which is now made integral with the tool, is rotated sufficiently'until seat A of the faucet will have been cut to a perliect state. The tool is then removed from the faucet in the same manner as it was prepared and inserted therein, and the faucet reassembled for use. 7 n An important feature of the, invention is the pressure feed effected fornuttingjaws 1 as the tool is rotated with respect to valve seat A. This is accomplished by means of bonnet C of the faucet, which is readily apparent Figure -1'. 7

While I have herein set forth a single embodimento-f the invention, the same woulda-nticipate certain minor changes in the :details offcenstruction thereof, if this condition should present it'- self during any probable further development for the market, however in any eventualityja ,depa-r ture from the general principleinvolved would be consistently avoided. V i r i A Having thus described my invention, what I claim was new is:--
