Appiication med August 2, 1919. serial No'. 314,993.

To' all whom t may concern.'

Be it known that JOHN SALMINEN, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus for Re seating Valve-Body Seats, of which the following is a specification.

This invention relates to apparatus for seating valve body seats of gate valves; and has for an object to provide an apparatus of this kind adapted to reseat the valve body seats of valves from which the valve cap and stem have been removed but which are still connected to the pipe line.

Other objects of the invention are to provide an apparatus adapted to be easily mounted upon the flange of the valve barrel and to provide an apparatus of this kind in which the reseating tool ma`y be fed either automatically or by hand.

Other objects are to provide an apparatus of this kind which will be efficient and durable in operation, which may be economically manufactured, and which will not get out' of order; Y

Other objects of the invention will appear as the description proceeds; and while herein minutev details of theinvention are described, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed.

In the accompanying drawing forming by wayof example one of many possibleembodiments of the invention- Figure 1 is a side elevation of my mproved apparatus shown applied to avalve barrel, the valve barrel and body-seat being.

shown in the vertical section;

Figv 5 is a horizontal sectional view taken on the line 5 5 of -F ig. 4, and

. of the upper end of the apparatus,V

My improved reseating vapparatus is shown as applied for reseating the valve body seat 10 of a gate valve, fromthe valve barrel 11 of which theV valve cap andv valve stem have been removed.

The apparatus is supported onan lshaped base 13 having supporting arms 14 resting upon and adapted to be clamped upon the flange 16-of the valve barrel. Said base is provided with a'vertical body portion 18 formed with a flat vertical slide-way 19 having an under-cut beveledrfixed guide 2O at one edge. At the other edge of the lslide-way there is provided an under-cut beveled adjusting gib 23Vheld in place by a headed bolt 24 engaging in said body p0rtion 18.

The operating mechanisms of the apparatus are mounted upon an adjustable support 25 comprising a vertical, beveled slide 26 held in said slideway by said guide 20 and .l

tical bores 30 and 35 is provided with aseries of vertical holes 43 (Fig. 6) in its upper end; and an upper driven bevel gear 45 is fixed on said sleeve abovev said upper bearing bore 30 and is engaged by a'driving gear 46 mounted' on a drive shaft 47 mounted in said upper horizontal bore 31, and connected to any suitable drive means or source of power not shown. .Y

A feed shaftv 50 is disposed in said sleeve 42 and projects at both ends of the sleeve, and is provided with a hand wheel 51 fixed on its upper end and resting on said sleeve.

Said wheel is provided with a handle 54 and with a small bore 55 adapted to register with any one of said holes 43. A locking pin 56 in said small bore 55 may rest in any Vone of said holes 43, whereby the sleeve 42 and feed shaft 50 may be locked together at will. A Y

A journal shaft 60 isrotatably mounted Vin said lower horizontal bearing .bore 36 and is held in place by a retaining plate 61 se-A cured to the outer end Vof the journal shaft with the inner end of saidV journal shaft is provided with peripheral bevel-gear teeth 65, a diametric feed-screw receiving bore 66,

a diametric under-cut guide-way 67 and an Velongated guide recess 68 in the bottomof said under-cut recess and communicating WithisaidY feed-screw receiving bore.V A feed Iscrew 70 is provided in said screw-receiving Y ing gib 77 in one side of said guide way prevents lateral 'playv of the toolv carrier.

A tool head 80.is for-med on the end of said tool carrier and is provided with a diagonal tool-seat opening/,[81 provided inone wall thereof with a longitudinal screw receiving recess 82. ln -said openingis dis-V posed a tool block 85 'providedI with interrupted thread'sr86 and with a'toolireceivin'g recess 87 receiving a tool 88 against a, shoulder 89 at 'the' rear of the recess: A clamping screw 92 in said head holds the tool in Y 'placeandpresses it against said block." An

adjusting screvv'94 in said screw-receiving recess 87 engages said threads 86'and serves Vfor adjusting the block whenV ther adj listing` Y screw isrotat'ed by a suitabletool, Said screw 94 is Yheld against longitudinal movement'by the heads 95 and 96, one, forii'n'- stance the head 96, is adapted to-receive a wrench-for adjusting the tool block. Y

A drive pinion 97 onV saidsleeve 42 en'AV gages the teeth of said supporting gear 64 and drives the supporting gear when the shaft' 47 is rotated. VA double idler gear 98 Vis rotatable onv said seatv 38 of the bearing bracketv 34 and engages said feed pinion 7l;

'Y and a feed drive gear 100 on said feed shaft i are locked 5()v engages said idler gear 98, thereby rotating the feed screw and feeding the tool carrier when thefeed shaft'50 is rotated. Y

The teeth ofsaid supporting gear 64, said drive pinion 97, said *feed'pinion-71, saidV idlergear 98, and said feed drive gear 100 have such ratios thatV the` feedV screwl willV feed out when said sleeveY 42 and feed shaft together, by the pinf 56, andY rotated. Y Y Y The operation of, the device will beV read? ily understood fromthe foregoing descrip- Y l,tion and need now be'V described only briefly as follows: f j The valve cap andistem being. removed,

the basel?) is placed Vupon'thevfiange ofthe valve barrel, andthe bolt 24 loosened sufli-AVN ciently to permit theV supporting member 25 to be adjusted until' the axis of the journal shaft 60 is placed in alinementwith the valve body seat after which the bolt 24 is tightened, to lock the member 25. The Vpin Y 56 is then :Withdrawn and the handle 54 revolved until the tool 88 is withdrawn to within 'the valve body seat, whereupon the apparatus ismovedtoward the valve seat to a position for taking a light cut from the seat. Y The-base 13 is then clamped in place by suitable clamps, and the shaft48 rotated andV the'tool revolved until it is seenthat the proper alinement has been made. Power is then applied-'and Vthe tool revolved and gradually fedoutward, thus taking a light cut from the seat.V Y

VThis outward feedingV maybe made 'by manual operation ofthe hand wheel 5l or it y maybe accomplished automatically merely byA loclingthe feed shaft and drive p sleeve together by means of the pin 56, the

Vdilfeienceii theratios ofthe several oper- Y ating gears causingV a gradual `feeding out of the tool carrier as the tated vforwardly.

Y Kftervthe first 60 is withdrawn and the 1 tool is'carried back to its initial position on thesupporting member'64 by manual operation of the wheel apparatus is yro- 51.V The screw 92 is then loosenedy andthe tool block fed outa small amount by Y manipulating Fthe f adjusting vscrewV 94; Y Another cut may then be taken from-the valve body seat, and thelop'eration repeatediuntil the desired reseating has been effected.
