Similar letters of reference indicate like parts.
A represents a spring,`wh ieh is formed by splitting a bar of steel, B; or said har may be of iron or steel, forged or made separately, with the spring welded toit. The outer end of the bar B is curved or bentground, as shown at a in fig. 2; and the inner end o f said bar is forged with a cross-plate, b, which is eat in" the jamh, c, of the door-frame, and secured thereto by screws, ol, the cuter surface of the cross-plate beingusl1 with the outer surfaceof the jamh c, so as to admit of the door, e, closing against the shoulder-piece, f, ofthe jamb, as will be understood by referring to iig. 2.
The spring A projects out from the bar B within the path of the movement of the door e, so that the door in closing willstrike the spring and force it towards the bar B, the resistance of the springheing suiiicient to overcome the velocity of the door'before it comes in 'contact with the shoulder-piece f, and prevent the former from slamming.
This spring may be applied'to the jamh of thel door-frame, or to the top.crosspiece of-the frame, and even to the side piece, if desired. In general, however thc jamh o f the door-frame will bo themost convenient place.
