In the accompanying drawing wherein a A-peripheral groove'26 is formed .ln the 'stlld 1" preferred form of construction for our in- '25 and defines a shoulder-27; {A screw '28 is Q I. vention is illustrated, 1O indicates the base of mounted in an opening29; in the spindle 17 our improved machine. 1 Extending upwardand this opening"29 is; preferably aligned 1y from the baselOis a supporting column 11 with the groove 26 whenfthe stud 25 is dis; which has at the upper end thereof asupport posed in the recess. 23. It is, therefore; 1 j arm 12 hich extends at right angles to manifest that the screw-28 may berun'in- 5 the column 11. Adjustably mounted on the wardly'and be disposed in the groove 26. 'By column 11 isa sleeve 13' which has portions reason of the weight of the type'holder- 24 f 14' projecting therefrom on which a work it is manifest that the same will tend to move supporting table 15 of approved formis r the stud 25 from the recess 23. This will be mounted. Atthe free end of the arm 12 a prevented by engagement of the shoulder 27 sleeve 16 is provided and this sleeve 16 is v with the screw 28. -;The screw'28, has a rod gripping extended therethrough at right angles to the extent of the screw 28 which provides a portion to facilitate turning of the screw 28. In addition to the rod 30, tool grip 31 is provided on the outer end of the screw 28 which may be also utilized in v the turning thereof.

It is manifest that engagement of the screw 28 with the shoulder 27 will prevent removal of the stud 25 from the recess 23. Retraction of the screw ,28 from the groove 26;wi ll manifestly permit the stud 25 to be with drawn from the recess 23 and in this manner the type holder may be expeditiously detached from the spindle l7. it is also apparent that when the screw 28 run inwardly into engagement with the' "bottom of the groove 26' that the stud 25lmay be secured against movement-in any direction. low? ever, when the screw 28 is moved from engagement with the bottom of the groove 26 but is retained in engagement with the shoulder27, it is manifest that the stud 25 will be held against removal from the spindle 17 but also thatthe'stud25 may be rotated relative to the spindle l7 and, therefore, the type holder 2d may be arranged in various angular positions with respect to the axes of the work receiving table 15 and it is also apparent that after thetype holder 25 has been moved into these angular positions that the screw 28 may again be engagedwith the bottom of the j groove 26 to lock the stud 25 against further movement. r I

' It is manifest from the foregoing description that we have provided an arrangement for associating a type holder or the like with a spindle which will permit expeditious-re- JDOVELl'Of the type holder. from the spindle and one which will also permit the type f holder or the like to be disposed in various angular positions'wit-h respect to the spindle.

While we have illustrated and described the preferred form of constructionfor carrying our invention into effect, this is capable of variation and 'modification, without departing from the spirit of the invention. We, therefore, do not wish to .be limited to the precise details of construction set forth, but

desire to avail ourselves of such variations a stud projecting therefrom having a groove in the periphery thereof, said stud being disposed in said recess, and means carried by said spindle for extension into said groove to. retain said stud in said recess.
