Thisv invention is directed to an improve-k ment in universal inountings `for valve-sea cutters and reseaters of tl etype described and claimed in PatentpNo.
5 May 1,1928.
In the type of mounting disclosed in the patent referred to, the cutter-arbor guide was terminally formed withv a ball seatingin a correspondingly shaped receiver provided in faces of arms arranged for clamping to hold the ball and therefore the guide in any set position. The wall of the receiver was of properaneignen-slipping .cooperation with the ball.- This particular construction has proven to have some `commercial disadvantages in that the babbitt bearing in the continued use of the `tool is gradually worn away and at the Sametime becomes more'` or less deformed under the pressure with a resultant uneven pressure on tlieball and a tendency to deflect under such unevenpressure.
tool necessitates a very close, free,v sliding lit between the cutting arbor Vand arbor guide and inthe continued use ofthe tool, particu-y larly under the liability of imperfect lubrication, the bore 4of the arbor guide :becomes worn to an extentgto niateria'llyinterfere with the desired accuracyof the tool. Under these circumstances,the arbor guide must of course be renewed and this reqiu'i'esaV new ball terminal, as such ball'rterminal is integral with the guide, and the new'ball terminal necessi- -7 tates a new babbitt metal bearing in the arm and the relnishing of the arm as the heat of the metal destroys the finish. Thus, 'even'the normal wear in the arborguide results in the necessity'for a renewing of a number of parts whichsliouldnot ordinarilyrequire renewal and hasl provenV a matter of more or less serious economic consideration from a commercial standpoint.
vention to so construct the sevevra'lparts "as to insure their effective Vservice and yet render 1,667,918, issued' babbitt or like metal to insure small Vvmatter of the former gripping element and securing vmeans, theseparability of the gripping element 'from the arbor Furthermore, the required accuracy of the It isthe primary object of the present ini-l member,
diate renewal by a stoclrvr part and thereby `avoid the-necessity for replacement of parts not necessarily affected by Wear and avoiding the necessity for returning the parts to be renewed tothe factory or other point having facilities forthe renewal'heretofore necessary. r f l In this particular, the invention comprises a gripping element having anlexternal spherical form and an internal diametric opening to receivethe tool arbor guide, the element thus provided having its Wall divided ona diametric line to form separable sections,
with means which these sections may be removably intertted with the tubular arbor` guide ina rigid, non-yielding, noitcompres# sible manner. Thus, the renewal of the nori'nallyfwearing' part, the` arbor guide, is a' replacing that guide, using guide facilitating this replacement. v Y
The invention also'c'ontemplates the pro-A vision of a base lto be removably fixed on the engine block, With means carried by the base whereby the arbor-guide and its cooperating elements may be readily and conveniently ad justed for the initial centering of the arbor guide Withrespe'ct to thevalve seat being operated upon. "U Theinvention is illustrated in the accom- Lpanying drawings,` inwhich:
Figure l is a perspective View of the mount,-
Figure 2 is an enlargedsectional view of the clamping members, gripping member, and guide Vin cooperative relation. v
F iguref is an enlarged sectional y View through'the parts providing for the rotative movement of the mounting as a whole.V` igure 4 lis al perspective View of the gripping member.V i
The improved mounting comprisesa base adapted to" be removably iiXedon the engine block, a supporting member mounted for rotative adjustment on the base, a clamping means adjustableto''andV from the supporting anda gripping member 'and cutterles Y arbor guide cooperating with the clamping means.
In the preferred' embodiment illustrated, the mounting comprises a base 1, Jformed with a slot 2 to receive one of the usual removable head clamping bolts of the engine. By this means, after removing the engine head, the base may be secured in a convenient position on the block with a rotative adjustment in such position limited only'by the extent of the slot 2.
To secure the supporting member in proper relation to the base While insuring the absolute accuracy-ot its relation to the base, said support-ing member comprises a divided body 3 having a at face l bearing squarely on the flat face 5 ot an upstanding part 6 ot the base. The supporting member is formed with an offset sleeve portion 7 integral with the respective upper andlower portions 8 and 9 of the divided body 3, to provide for contracting move-ment ot the wall of sleeve 7 when the body parts 8 and 9 are forced together.
The lower body part -9 is formed with a circular guide lug 10 extending below its face l and seating with a sliding lit, when the parts are assembled, in a correspondingly shaped recess 11 in the upstanding part- 6 ot the base. A rod 12 passes through both parts ot the body and through the lug 10, being threaded into a threaded hole 13 in the bottom oit the recess 11. f The upper end of rod 12 has its threaded upper end projected above the body 3 to receive a clamping handle which, when appropriately turned, will secure the supporting member rigidly on the base and at the same time contract the sleeve 7, or loosen such parts in an obvious manner. n
The clamping parts for the cutter-arbor guide. include a rod la fitting the sleeve7 and obviously adjustable therein both rotatively and longitudinally, and clamping arms 15 and 16 carried by or integral with Athe rod. T he arms 15 and 16 are of semicircular form in plan and have a substantial verticaldimension. The terminals ot the arms khave cooperating outstanding radial ears 17, one of which is-tormed with a threaded opening to receive the threaded end of a.r handle 18, which passes loosely through the other ear and is provided with a collar 19to .bear against such ear. By operation of the handle, the ears and therefore the arms 15y and 16 inay be moved toward each other for clan'iping cooperation, or from each other for unclamping. 'Y Q p i A vgripping member-20 is provided to cooperate with the clamping arms. This member comprises ametallic body externally of spherical form and having an axial bore 21.
f T he body is .divided units diametric line,
providing two spherical segments 22. Av
cutting arbor guide 23 in the form of an elongated sleevelike member and designed to slidably and rotatably receive the arbor on which the cut-ter is mounted (not shown), has an external diameter throughout its lower portion for a sliding fit in the bore 21 of the gripping member 20.
The lower end of the guide has an annular offset 2e to receive the lower edges of the spherical segments 22, such spherical segments throughout the area cooperating with the oilset 24 being flattened, as at 25, to accurately and snugly bear on said osets. The arbor guide above the gripping member receiving portion is exteriorly threaded, as at 26, to receive a. clamping nut 27, the lower surface of which presents the square abutment 2S to bear upon a flattened portion 29 at the upper extremity of the spherical segment sections 22.
Thus, with the sections in applied position on the arbor guide and the nut 27 tightenedll it is apparent that the sections are secured in a substantiallyy rigid manner to the arbor guide and form in-eliect a. spherical or balllike enlargement at the lower end of the guide. v
1t is important that under the clamping pressure of the arms 15 and 16 on the gripping member, as will later appear, no appreciable clamping pressure of such gripping sections be had on the arbor guide. To insure this it may be found necessary to provide ordinary shims between the meeting edges of the segment sections 22 to insure absolut-e accuracy oi the internal bores of such sections with the external diameter of the Aarbor guide to prevent any possibility ot clamping action of the sections 22 on the guide. The sole connecting relation between t-he spherical segment sections 22 and the arbor guide is through the clamping of such sections on theguide between the oiiset 2l on the guide and the nut 27, it being understood that the bearing surfaces between the segment sections 22 andthe offsets 24 and between-such sect-ions and the nut 27 are carefully 'formed to insure uniformity of contact throughout to Athereby hold the sections 22 in rigid relation Yto .the arbor guide under the clamping action of the nut 27.
The inner surface of the clamping arms 15 and 16 are recessed on sphericall lines at 3() to accurately receive the gripping memberfand exert binding pressure thereon under clamping action or the arms to rigidly hold the gripping member and arbor guide.
In operation, the arbor guide is to be aligned with the valve guide of the particular valve seat, as described in the patentabove referred to. The -basel is adjusted on .the block and secured; the supporting `member-is adjusted-and secured; andl the-arborguide is aligned =with'the valve guideef the valveY seat to b e recut or reseated. After placement of leu `the parts in unit the arbor guide, the clamping arms are to be tightened by handle 18 to hold the gripping member in its then position and also to bind said member and the-guide.
It will be apparent from the above construction that in the naturalwear to which the tool is subjected and the necessityl following' such natural wear for the' renewal of the arbor guide, the replacement of' such guide is a simple and easy matter. The removal of the clamping nut instantly frees the sections 22 of the gripping member and these may be readily replaced andy clamped ontoa new arbor guideavailable ordinarily from stock, by the simple expedient of positioning the sections 22 and applying the clamping nut 27.
Of course, in the new application, the use of appropriate shims to prevent clamping action of the segments on the arbor guide is of 1 importance and as it may well be that the exterior diameter of the replaced guide differs slightly from that of the worn guide, care should be taken to use the proper shims to insure the accuracy of .fit required; This, of course, is a detail of assembly well understood by any mechanic and the provision of several shims of different thicknesses as a part of the original tool equipment may readily take care of these renewals. Therefore, in the absence of breakage, the renewal of the part most subjected to wear is a simple mechanical operation androne requiring' but a few moments time, so that the'tool is practically not out of service at all by the requirement of replacement of the worn part.
The spherical form .gripping member is constructed in two parts which, in addition to other advantages, permits theassemblage oi form within the clamping parts, as it is apparent that if the gripping member was in the form of a single unit, it could not be placed in and removed-from position iii the clamping parts. lhere theV gripping member is divided into two parts as shown, the sawing element which divides the material will, or' course, take out a certain portion of that material inthe cutting operation, that is at least to the thickness ot the saw. Shimsof appropriate thickness, used between the parts, will replace the metal cut out by the saw and thus the gripping member will, in use, be in true spherical form.
What is claimed to be new is: l.
