This* ini'nantion` is an interrupter point 'grinder and.consists of` the novel featuresl herein shown, described and claimed. Y
An 'object is to make a lSimple vdevice which will hold g any of thevarious constructions carrying interrupterpointsand grindflat4 point' grinder embodying the principles ci our invention. y y
Fig. l is a perspective interrupter point grinder set up for holding and grinding one iormofinterrupter point.
Fig. 2 yis aside elevatlon as indicated by *i the arrow 2 in Fig..1,jparts being-broken away and shown in section.
Y Fig. 3 Vis a plan View Oft-hejparts shown" AVin Figs. `1 and 2 'and showing a different operation.
. Fig. 4I is a plan viewanalogous to Fig. 3
showing still another operation.
Fig. 5 is a side elevation as indicated by" thearrow 5 in Fig. 4. Y
The de tails of'construction and operation shown in the drawings are asfollowsz' The .ibase 1 is rectangular in plan and has -a iinishedrhorizontal upper face V2; and av 1 second: finished horizontal upper face 3,v
there being a vertical finishediface 4 con-l necting the adjacent edges of the faces 2 and 3. Theface 2 is substantially twice as 'Wide as the face 3. I i
' The sliding carrier base 5 is rectangular in plan and has a. finished flower face 6 so that the base 5 will slide freely upon the face '2, andhas -a `finished. side face 7 to slide Vfreely againstthe face 4. Round pins 8V and rv9 are'plfiXed in the carrier base 5 in transverse alinement Vand in -a line crosswise ofV the faces 2, 3 andv4. Expansioncoil springs 10 and 11 are mounted upon the carrier base raround the pins 8 and V9. The clamp# carrier 12 has vertical openings'V to receive the pins 3.'` and -9loosely and rests uponthe springs 10and 11, the tensions of the springs" being exerted to hold the carrier 12 elevated. g A slot 13 is formed from the end of the clamp carrier 12 which extends over the face 3 and a clamp screw 14 is inserted horizontally through the material at one`A side of the slot 13 andy tapped through the material atthe other side of the slot so that byv tightening j the screw the 1 clam ing' i tongues A15 and 16 fon opposite 'sides o the i ,slot 13 are drawn]toward'each-other; i Verti-Y`v `cal `:circular openings- 1 are y formed along the slotrlfthe openings being of various Vsizesas reouiiredV to 'receive and, clamp' posts',`
studs; binding-"screwsfand interrupter point n f inserted into ythe desired oneV of the Lvopenings 17 and clampedV byimanipulating 'the screw y.142,and. then the carrier12 is Vmanu-v ally pressed downwardly to bringvthe face carrier 12 are 1 manually f'moved .-longitudi- -nally-to producethegrinding action.- Inl l Fig. 1, the grinding action VVwill be a straightl v reciprocating motion fit the face 7 [bears upon the abrasiveY material 19'may be varied in,parallel'lines'bynmoving the base 5 to or frointhe, face 4. In Fig.' 3, thecarrier` 12 is applied fonlyl toone of the pins 8 or 9, and
levels and finished vertical tace connecting confronting edges of the horizontal faces, a sliding carrierfbase adapted to operate upon Vthe loWei iinished face, pins projecting ,upwardly fromv the sliding carrierV base,v expanson'springs upon theV pins, a
movedfto grind theV points.'vv
K Yziriousfchanges may he ,made Without departing @from the spirit :of our invention I as elamed..
Ne claim s* v An `vint-ferrupter [point .grinder .comprising moved A1to .grind thepoints,
a hase-having two horizontal finished uppeif `feces on different levels and a finished V'eiti cal face connecting vconfronting edges of v vthe horlzontalvlfaces, a sliding.certifiery base' adapted to operate uponsthe lower l,finished face, pins ,piojeeting/upwardly;from theY sliding carrier base, expansion springs upon the pins, a clamp carrier slidmgly mounted upon the plus againstitlie springs, and means .for clamping Vyzirtielesr-*having interrupte1.V points to the'dampeatrier soV that ,theilnten iupter points may he engagedwith'brsive material upon, thef upper finished face and Y In testimony Wheeof ywe names to this speeiezi'tion..
