ADJUSTING im'v cr: FOR ROTARYGRINDING-MACHINES.
Specification of Letters Patent. Patented Aug. 20, 191
Application filed December 29, 1911. Serial No. 668,509.
To ali'whom it may concern: Be it known that I, ALBRECHT Waonnn, engineer, residing at Ufnanstrasse 2, Berlln, N; Germany, have invented certain new and useful Improvements in or Relating to Adjusting Devices for Ro-tary Grinding- Machines, of which the following is a specification. i This invention relates to adjusting devices for rotary grinding machines or devices for moving the grinding wheel or disk, or more strictly speaking its'support away from or up to the blank or work in the machine. Hitherto suchdevices have been actuated by. the reciprocating of the Work slide or operating table but this arrangementpossesses the disadvantage that as soon as the mechanism for moving the slide or table is thrown out of operation as is, for instance, necessary in connection withsurface-grinding or the like, an automatic adjustmentorsetting of the grinding disk or wheel cannot be effected. v
The present invention has for its object to overcome the. above disadvantage and it consists in adapting the adjusting dVlC')-t0 be also operated, when required, by the driving gear of the machine;
The invention also comprises other details and arrangements hereinafter more particularly referred to.
The accompanying drawingsillu'strate one mode of carrying out the invention.
' tated through the medium of a pawl 5. In
Figure 1 is a side elevation showing one convenient form of apparatus constructed inaccordance with the invention. Figs. 2 and 3 are respectively frontelevations showing a portionof the driving mechanism in two different positions.
In carrying the invention into effect in one convenient manner, the grinding wheel or disk 1 is arranged upon a support 2 which is reciprocated in a known manner through a spindle 3 adapted to be operated by-ineans of a gear wheel 4 which is lntermittently rothe known arrangement the feeding or operating device or pawl for the ear wheel 4 is intermittently operated byt e to-and-fro movement of the table, said operation being effected in the following manner :-'The table or slide 6 carrying'the work is provided with a rack 7 which is adapted to bei driven by,
.aboutthepin D with the bevel wheels 12 and 13 loosely 'inounted upon the shaftlet which is con- 13, by which means the gear .wheel 11 is.
alternately turned to the right or to the left, thus moving the table 6, in the one direction or the other depending upon whether the coupling is in engagement with the wheel 12 or 13. A member 21, preferably curved as shown .in the drawings, is secured to the extension 17 and carries in any'sui-table manner a rack 22 which engages with the wheel 23, the latter being provided with a crank 24. adapted to move up and down a slide or carriage 25 to which pawl engaging with the gear wheel 4. When the extension 17 is caused to swing out by means of the stops 18 and 19 the member 21 and consequently the pawl 26, are moved, thuscausing the wheel 4 to move in such a manner that upon a change in the movement of the table or-slidethe grinding disk or wheel is adjustedor set by acertain amount in'relation to the work. 1. Such an arrangement as that above described is, however, known per se so that its modeof operation need not here be described-in detail.
fAs in the arrangement so far described the adjustment of the driving elements for the setting mechanism of the grinding wheel or disk support de end upon the movement of the table-orsli e, the grinding wheel or disk'supportecan be automatically adjusted only when the work is moved to and fro past the grinding wheel or .disk that is to say, when the work slide is-reciprocated. In order to allow of automatic adjustment of the grinding disk orwheel support when theo'perating table is-stationar'y a worm 27 is arranged upon the shaft leand. gears with a pawl 26 is pivoted the upper end of said 7 a worm wheel-28carryinga crank 29 adapt- I i ed to move a. rocking .pivoted grii'lg f w eel or.

adjusted when the operating table is at a standstill the rack 22 isdisconnectedfrom the member 21 and connected up to the member 31 and. secured upon the same at any suitable position by means of the screw 32. The remaining driving elements 23, 24;
25, and '26 remain in their original position and the clutch 15 is moved into a central position soot-hat it does not engage either or the wheels 12 or 13, the resultbfthislatteir arrangement being that the wheels 11, 9, 1 8 and consequently the table or slide6, are at a standstill. When the machine is in operation the member 31 isrocked about its pivotal support through the medium ofthe shaft 1 L w0rm27, and gear wheel 28, and" in this manner the: pawl 26 rotates the gear wheel 4 so that an fllltOIIlfitiQ-ndjUStlIlnt or setting of the grinding wheel or disk supportresults in spite of the fact :that-the operating table is stationary. If the autow matic feed of the grinding wheel or ,disk' support is again to be made dependentlupon the reciprocating movement of theoperating table, the rack member 22 ismerely disconnected from the member 31 and againlsecured t0 the member 21 while the clutch 15 is coupled with either of the bevel wheels- 12 or 13 whereupon the wheel 4. is mm'ed in the manner above described so that the automatic adjustment of. the or disk isseo ure d.
- The foregoing de'ser'i" tion is given by wayof example only, and t 1e invention is not to be confined to the details of construction hereinbefore given such details,land the as described.
