In the construction of lathe dogs and carriers it is essential to construct them as light as possible, compatible with the strength required to securely grip and rotate the work to be operated- on ; also to proportion and distribute the metal throughout its parts so that it may be balanced, or nearly so,- on its contra of rotation when in use. To accomplish these desirable ends is the object of my invention; and it consists, first, in casting the body of the dog or carrier with a core throughout nearly its entire -extent, whereby a stronger instrument is produced with less weight of metal; secondly, in disposing' and proportioning the metal in the throat opposite the gripping screw and around the angle of the tail or carrying end in such manner as to insure the dog setting square upon the work, and at the same time to counterbalance the heavier end of the said dog and give proportionate strength to the parts subjected to the greatest strain, and thus produce a steadier rotation of the work and a more serviceable and consequently a cheaper instrument.
