6 extending'to the sleeve-like bearing, as shown. To the opposite sides ofrsaid'extension 5is bolted a pair of angle bars 7, 7

so that two of their flanges lie flatwise' against said projection in parallel spaced relation to each other andthe other flanges project outwardly apart at the edge of the extension next the sleeve-like bearing 2, and

at their opposite ends are secured toa head 8 to theopposite sides ofwvhich they are I bolted in the same parallel relation as to the foot or base piece 1.

This head 8 comprises a body, against the opposite sides of which the parallel flanges of the angle bars 7, 7 lie, and above the other flanges the head provides a fixed jaw 9 adapted to engage the work and which ex tends transversely across the body portion and work-supporting flanges of the angle 1 bars. The body portion of the head is aperjaw '9. This adjustable jaw 13 sits upon the v v '31, adjacent the sleeve-like bearing 2 and tuned below the jaw, and between the angle bars 7, 7 so that a screw 10 projects therethrough and is adapted to receive-a handled clamping nut 11 at the front of the head,the-

rear end of the screw beingattac hed toa connectingdraw bar 12 which extends backward'between theangle bars of the clamp and is secured at its rear end to an adjustable jaw 13"overlying the angle bars transversely thereofv and adapted to engage the opposite edge of the work from the fixed top flangesof the anglebars 7 and has arms 14, 14 extending forwardly downward between and; adjacent the parallel .flanges of the angle bars and-provided attheir lower end with ledges 1 5, 15 to hook therebeneath, all as clearly shown in Figures 2, 3 and 9.-

Adj acent the jaw proper and attlie back of the same, the arms 14, 14 are connected by a cross-piece 16 which servesas a rest for the connectingv strip 12,'and directly above said fixed relation to said strip. The latch 17 can rest;.i s, the free end of a latch 17 pivoted to the back'of the jaw proper and which is normally, forced. downward by a spring 18. into any one 'ofa longitudinal series of apertures ing the rod, but I have shown it as adapted 19 in'said strip '12, so as .to secure the jaw in be released by, its handle and set at various points' along the length of the connecting strip, .according'to thewidth of the work to be clamped, and it will be understood that after it'has been so located as near the width: oft-he work as is convenient, the clamp is head as by'a screw 22, provides an arcuate flange 23 which lies outside an annular. flange 24 on thenut and adjacent the front of the head, as shown in' Figure 2". 'Preferably this locking member is grooved at its side next the head, as at 25, to fit 0ver a rib '26 to prevent any lateral displacement. The head receives the screw 10 loosely, as at 27, and furthermore is longitudinally grooved at opposite sides of said aperture, as at 28, 28, to enable the connecting strip 12 to be inserted from the front of the head. Preferably wings 29 29 project from the rear of the lower part of the head to lie against the in ner facing sides of the parallel flanges of the angle'bars 7, 7 and be riveted thereto, as shown in Figures 2 and 3 more especially,

and also said wings have at their upper edges with the bottoms of the grooves 28, 28 in j the opposite side walls of the aperture 27 of the head, as'clearly shown in Figure 8.
