P i V f i 1 with respect to the weight Q9. This means comprises a bearing clocki- 31l niojfably mounted in an opening in the i-afeight 29 andhzwng un arcuate 'ce adapted to bear against the pedestal 33. A bolt 86' passes through the bearing block and is threaded in the weightV 29, the head of the bolt overlying the bearing bloclr so that when the bolt is rotated the block will be tightly jammed against the pedestal 33.
A collar 37 surrounds the pedestal above the weight 29 and has a key lying n a slot 38 in the pedestal, so that it isnon-rotatable with respect thereto, butfis capable of relative vertical adjustment 'so as to li'e at all times on the top of the weight 29. This col- `lar has a series of suitable graduation marks 39 thereon tocoperate with a inarlr 40 on the weight, so that the angle to which the pedestal 33 may be turned inthe weight is conveniently indicated. 1n addition to the adjustment of the work-tableaiordcd oy vertically moving and by rotating the pedestal in its support, `the work-table may be adjusted toward and from the grinding wheel l'by sliding the trunnons 8O in their bearings. When the table has beenadjusted to the desired position, the shaft 8O may be secured against sliding movement by means oft nfthrust collar 30 and a collar 30 fixed.
upon the shaft at opposite sides of the bear- By extending the base and providing the forward bea-ring 28 to support the forward end of the trunnion or shaft .30, a. very marked improvement in the accuracy of the nachine is attained. In rior disk grinders` the rear end only of tie shaft was supported, and the Tv'orlr-table was mounted on a relativ-ely short sleeve or bearing which surrounded the shaft and was rotatable thereon. -fi In Such a 'construction it is inipossib1+.=, tol prevent slight springing of the forward end of the shaft and it is also imi 'the tension oftheLs Jring. When the'crank 'handle and collar' 5' a'erigdly connected possible to` prevent 4play ofthe short su1i porting sleeve or bearing on the shaft, and
)een .of these movements are fatal to nice- V.accuracy of work, because the movements are much exaggerated 41n the plane of the top of the worletable where the .work is sup# ported. In the present machine, the shaft is mounted in two bearings whichl arespeced a material distance apart and the shaftitse'lf is arranged to rotate 4in thev bearings; the' work-table being'rigidly fixed to the shaft so that both of the objectionable forms of looseness or movement above mentioned are com; pletely eliminated. Furthermore, a con,
struction is p1oduced'-which will stand up the upper end of the pedestal 33. The base' 65 coinprisesa bottom plate7 and side walls 46 to move the'table top 49: A-looped handle72 lsite of .the base '15 for horizontal sldm movement toward and away from the grin 'flange 63 extending base45, which,-

The upper face of the top isrprovided with aplurality 'of undercutA or T slots 53 adapted to receive bolts for 'securing various work-su porting fixtures (not shown) vto :the table.; he lower side of the table is provided with a downwardly projectin rotatably mounted one end of u. shaft which shaft is additionally supported in a slee've 5G screwlthreuded in a bearing 57 in anges carrying plates 52 to,
