Heretofore such machines have been constructul for inserting the points into the sash I hypressure. This mcthodisohjeetionahle; (or the reason t a u s a c amp ng o ng-el theemachine to the sash to resistgthe reaction of the pressure against the point necessaryfor its --insert ion, thus rendering the op-- era-tron eomprrnti-selyslow; a 1

plriectofmy'invention" is to preside a glazier -pointsetter which will drive the-points without the necessitypf clampingthen achine' to the sash, and which will dothisaccurately m direction and depth and in close contact with the face of the glass, and which will be readily ad j-nstabie in the'i'orc'e of its blow, "according tothe-varying hardness of the wood of j the sash. p The invention consists .in a striker mov'ed backward by the action-of a leverand forward 30 by the reaction .ofa spring.

It also consists in the connection, with-said striker, of a driving-plate, said plate also forming an opening and closing bottom to the recep'tacle containing the points to be driven.

It also consists in an adjustable latchg-hy which the forceof the blow driving the point may be regulated.
