outer end of the shank l2 threaded, 'es indicated at lo, end receives an adjusting-nut l?, mounted thereon.

i8 indicates o spiral spring coiled on the projecting; extremity oi the shank 12 and bearing at one end against tlie iront or outer end of the housing 1G, while its other ond bears egeinst the inner ieee of 'the nut i7, the seine being preferably recessed, os indicated at i9, to receive and protect the outer end of the spring.

it will be seen that by tlieeinploynient in connection with the body or the trimmer of two gege portions located at the opposite ends thereof, and therefore seperated somewhat Widely, the said trimmer-body is given im extended support or bearing upon the wlfile the springoctuated friction guide- `olocks serve to hold the body steady with respect to the guide portion of the straightedge, not only preventing all looseness endI rattling7 but also serving to hold the trimmer in position at any portion oi` the straightedge to "which it maybe moved. This is ed ventageous for the reason that it prevents the trimmer from sli ig alongr und dropping oil' from tile end ol the stroigneedi f in tire lutter is held or pleoed in n posi. on other teen norizor l, end tiio operator is thus given greater 'ifeedinn in the liendling ol the streiglitedge.

, it t" understood, of course, that the springs i8 liold the friction guide-illecite in Contact with the roer edge of the port e of the metallic Vguide-strip ond the ienges 9 against the outer fece of the vertical part oi seid strip, which constitute lateral bearing surtherefory thus producing the desired friotionol engagement of the gege portions with Suid strip. it will also lie understood that the friotionul engagement ond weer nifty oe readily regulated ond taken up by adjusting the nuts i7.

The trimmer is applied to the straightedge at the end thereof, und the engagement ofthe gage portions therewith muy be readily effected by pressing buck upon the nuts 17 or on the outer ends of the slienlis l2, so :is to force the guide-blocks i3 for enough osait to erniit their engagement with the guidestrip. The body of the trinnner, tlius supported in a fixed angular relation to the straight-edge, carries a rotary cutter 20, mounted to rotate freely on en arbor 2l, pref eraoly in the forni of t screw-bolt. bor 2l is secured ecoentrioelly in u rotetory niernber'or shaft 2:2, mounted to rook or rotitte in n.
