Y
he frame is provided with suitable su ports for the object to be ground. In t e present instance the frame carries small braoketsi, having spaced ears 57, provided withfopenings for the 'assage of a screw 58, which may be adjuste by means of a nut 59, niiounted on .the screw at a point between the ears.' :Eachscrew carries at its inner end a collar'or ring 60, and .these serve as supports 1 may he tunned .in order to adjust its angular posimay bey locked v. time the gear 80 is tionevith relation lto the revoluble -abrading member. AOne o the end pintles carries a suitableeadjusting-lever 63, and when the bar has been turned to the desired position it by suitable set-screws 64. 'Ehe .work-carrying bar is shown in the present instance as supporting a knife that is held inlproper relationto the abrading membelt v `During the operation of the machine the drum 19 .is continuously revolved in the direction indicated bythe arrow, and this movement is transmitted through the gears 22 and 23 tothe eountershaft-24- At this connected tofthe shaft 135 hy the yclutch 33,-and as the shaft 24 is re solved the movement ,is 'transmitted from pinionQS and gear-wheel 'to` said shaft l5, v 'otating the shaft in the same-direction as g the drum, but at a slower speed,sothat as the drum revolves the nut 43 will he carried around the screw-shaft and vthe/collar 40 and abra-ding member 41 will be slowly moved toward the right, or in the direction indicated by the arrow, until near the completion of the movement the sleeve 49 engages the adjustable collar 53 and moves the rod 36 'oward the right. This movement brings the collar 37 into engagement with the upper end ol the clutch-operating lever, and the clutchsleeve 33 is moved into engagement with the pinion 29.l The first step of course is-to reease the gear-wheel 30,and after pinion 29 is clutched to the shaft the movement will be transmitted from the counter-shaft through the gear 27 to thepinion 29 and thence to the screw-shaft, rotating said screw-shaft in the same direction as before, but at a much.
-higher rate of speed. 'lhe speed at this time greater than the speed of rotation of the yshaft-revolvingl A"with the pinion 29into engagement with the gear-wheel 30.
'The operation may be kept up as long as necessary to completely grind the knife or other object, and the abrading .member will be reciprocated slowly in the direction of the length of the drum without stopping orinterfering with its revoluble movement.
I claiml. In a grinding-machine, the combination with a revoluble grinding member, of'a nut connected to and rotatirnf therewith, a threaded shaft with which tthe nut engages, means for alternately 4revolvingl the shaft at high and low speeds and in the same direction to thereby elect reciprocatory movement of said nut and grinding member.
2. In. a grinding-machine, a revoluble grinding member, a nut carried thereby, a supporting-drum on which thev grinding member is free `for rotative, and reciprocatory movement, a threaded shaft with which the nut, enga es, rotating the s aft in the same direction, to thereby effect `reciprocatory movement of the nut and grinding member.
3'. In a grinding member, -a nut carried thereby, a threaded shaft with which the nut engages, a
means, and means for antomatically changing the speed of said shaft to revolve thes'ame first at the slowerspeed than the nut, and then at a higherspeed than the nut.
l4. In a grinding-machine, a vrevoluble grinding member,a drum on which ,the grinding member is free for reciprocatory 'move ment, .means for revolving the drum and grinding Kmember, a nut carried b'y said grindingI member, a threaded shaft extending through the drum and with which said nut engages, means for revolving the shaft, and means for automatically changing the speed of said shaft as the grinding member nears ythe limit lof its reciprocatory. movement in both directions. v -r 5. In a grinding .machine, -a revoluble grindingI member, a drum on which said member is mounted, means-forrevolving the drum, a counter-shaft having a geared connection with'the drum, ageariand inion on the counter-shaft, a nut carried by t e grinding` -member,"a threaded shaft with which said nut engages, a inion and a gear mount ed loosely on tho t ireaded shaft and intermeshing respectively with the gear and the grindingmachine, la revoluble ICO rio
pinion on the'countor-shaft, va double-clutch i A 'means for automatically moving 'said sleeve to alternately engage the gear and the pinion of said threaded shaft.
6. In a grinding-machine, a shaft having a threaded portion, a drurn mounted o n an unthreaded portion of the shaft and arranged to rotate independently thereof, `said drum being provided with diarnetrically-opposed lon'itudinal slots, nieans for revolvinhi the drum, a collar slidably mounted on the drum,
la grindingi member carried by lthe collar, a
nut en'an'ing the threaded portionv of the shaft and having arn'isextendinv through the slotted portion of the drum and engalc'in' the collar, a eountershaft having a gearing;
connection with the drum., a gear and'pinionv on the counter-shaft, a pinion and a gear mounted loosely on the threaded shaft and interrneshing, respectively, With the gear and pinion of the counter-shaft, ajdoubleclutch sleeve fitted to the threaded shaft, a clutoh-operatin ,i lever, a slidable elutoh-op erating rod, adjustable collars mounted thereon, and arranged to engage the clutch-- operatin lever, a sleeve carried by the rod,
y va pair o collars With which said sleeve en- .'gages, arms depending from said sleeve, a
pair of rings encircling,- the grinder-carryin collar, pins extendinI from said rings an engaing said' arms, and means for support ing the article to be ground.
