. Appleton's dictionary of machines, mechanics, engine-work, and engineering. rod e. The yoke/ is placca in a horizontal position, and presents towards the table D a concave side,which is fitted to the groove in the rim of said table. Said yoke /has a vertical shot formed throughit, the longitudinal centre of which is in continuation of a right line extending horizontally outwardsfrom the centre of the axis c. By means of a stud 23 which extends upwards in a perpendicular directionthrough the aforesaid shot in yoke/ from the end of the lever g to which said stud is attached, a con-nection is formed between said yoke/ and said lever g, so that when said lever g is moved horizontally to the right or left hand, it communicates a corresponding movement to said yoke. The lever g isconnected by a vertical axis 24 to the fixed frame, as is shown also at 24 in Figs. 3063 and 3064; ithas a broad part in which is a slot or opening of sufficient dimensions to allow the shaft c to pass throughit, and to allow said lever to move forwards and backwards to a certain extent around its axis 24. Astud 25 is attached to the broad part of the lever g\ in a suitable position to receive the action of thecam h, which is fixed on the vertical shaft c. The cam h has two eccentric faces on its periphery, viz.,the longer face hi which extends around three-fourths of the circle of the periphery; and the shorter PIPE MACHINE, LEAD. 495 s93 face which occupies one-fourth of said circle. A spring 26 connects the end of the lever g with thefixed frame, and draws said lever in such a direction as to incline the stud 25 of said lever inwards to-wards the vertical axis c.
