Each of t hekrods as, an instance the rod 28, hasi'an engagement block 31 secured to the end of a fleXibIermember-BQ,

preferably spring steel roundstock, which member 32, inthe present instance, is secured to-ahpiece of square drill rod-33. aThe rods 28 extend parallel with onefanother' andvertically ftothe slots5 and 6, while the rod 30 is secured-to extendoparalleltotheslots 5 and 6andyertically to'the' slot 7. Y

W is used, the lower-=slot6 is preferably used to anchor the rods-28 and29 thereintto determine thelposition ofthe lower edge ofthe'sheet of work W. In thepresent instance; see Fig. 1 wher e'a 'shorlt pieceof work, a :card, is illustrated the upper "slot 5 is used to anchor the rods 28 and 29 in. place. The-slot? is used to anchor the rod 30inrplace, the block 310i which defining the position of the righthand edge of'th'e sheet of work W. The'imeans for anchoring I- the rods '28 and 29 inthe slot5= are substantially'identical. i The anchoring Ineans345see Fig. 4, consists essentiallyof a cylindricalmember-'35 havingtwo parallel recesses 36 and 37 extending para11e1 tdone another and to the face of thecylindrio'al.member Above the recesses 36 and 37 and extending at right angles to 'such"reces ses',there is provided an opening 38'extending fdiametrically through the cylindrical memberi in 7 "communication with theinternally threaded "opening 39; extending down-;axiallyitrom the upper end of the cylindrical member The threaded opening] 39 rece iyjesi the threaded portion of the set screw 40; The anchoring members 34 are positi oned'i'nthe'slots 5 6 and 7'; by 1 being initially introduced through. the

Therods 28,29 and i'ng membersei, may then beslid' into thea-n choring members 34 withfl their blocks 31pxtending 'toward the portion R of the] open ing 3.,

After the sheet of work hasibeen porarily anchored by theclips 26and27, as

illustrated in Fig. 1,.the rods 28and 29p are moved up untilthey engage the loweredge'of the sheet of Work W, whereupon the-set screw 40. is manipulated to tightly anchort'he-rods 28and29inisuch position. Similarly, the rod 30 willibe moved into position so that itsblock- 31engages the right hand edge of the she'etof Work W,fand thereupon-its. set screw Ois manipulated to engage "the rod 30 and-se 'curel y anchor it in position. By reference to.

F ig. 3-, it will be noted that the flexible member 32 is bowed downward toward theplate 2. In view: thereof, when'the set' screwO is screweddown, the' ' rods 28, 29 and 30 will tend tion '32,.thereby tightly anchoring the blocks '31 in. engagement with the surface beneaththe same. The openings 38, as indicateddnFig. fl, preferably afi'ord suflicient clearance for the rods 28,529and 30,s'o that the same'canbe W is used, it being obvious that without such ;s'upport'12 the blocks 31' would extend into the opening 3. Similarly, the sheet 16 will ,serVe-a ska support for the block 31 of the rod when a narrowpiece of work is used.
