v In Fig. 3, the tool-carrying standard D, shown in plan view, is supposed to be sta I tionary for use in connection with a longitudinally traveling work table. The wedge V is arranged before backofthe tools I in the standard and fed longitudinally by a rotating feed screw S which may be driven gearing 23 and! worm and worm wheel 24. I We claim as our invention: I edging plates having a thrust producing tool, an abutment meniher adapted to take up the thrust-pf the la t- 1 ter, in combination with means interposed between said tool and its abutment whereby i said tool is advanced or allowed to retreat as thework progresses along the plate to} i produce a plate tapering in width, said interposed means being suitably arranged to transmit the thrust of the tool 16 the ubulment member.

2. A machine for edging plates having a abuhnent member adapted to .take up the thrust of the latter,

in combination with wedge means inter- I posed between said tool and its abutment and adapted to transmit the thrust of said tool to said abutment, together with means to 11love said wedge means and'tool with relation to each other as the work progresses along the plate so as to produce a plate ta-i pering' in width, substantially as described. l

- 3. A machine for edging plates having a thrust roducingtool, an abutment member adapteu to take up the thrust of. the lattei and tool may-move to'and from the work in combination with a wed e member inter; posed in said vguide way between said tool and abutmentmember, and means where-by said wedge member and tool are moved with relation to each other as along the plate whereby the tool advances or recedes so as to form a plate tapering in width, substantially as described.

1. A machine for edging plates having a thrust producing tool, an abutment member adapted to take up the thrust of the latter and provided with a guideway in which said tool may move to and from. the work, in combination with a wedge member interposed in said guide way between said tool and abutment- ;member, and means whereby said wedge member is moved past said tool as the work progress s along the plate, whereby the tool advances or recedes so as to form a plate tapering in width, sui siantially as described.

In testimony whereof we have signed our names to this specification, in the presence of. two subscribing witnesses. -v
