FIGJ.
UNITED STATES PATENT OFFICEQ GEORGE RICH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE HALF TO JOHN RICH, OF SAME PLACE.
LATH E- CENTER.
SPECIFICATION forming part of Letters Patent No. 322,322, dated July 14, 1885.
Application filed June 16, 1884.
To aZZ whom it may concern.-
Be it known that I, GEORGE RICH, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a certain I111 provement in Lathe Centers, of which the following is a specification.
My invention relates to an improvement in the center-piece of the tai1-stock of alathe; and my improvement consists of a center-piece in which is a groove for permitting the proper application of a cutting-tool to the end of a pipe or other piece of work in facing the same,
7 or for permitting a chasing-tool to run beyond the end of the work to a greater extent than usual, all as fully described and claimed hereinafter.
' stock of the lathe, and the cone B, into which a portion of the pin A is fitted. The cone and pin, however, may be made in onepiece.
In facing the end of apipe or other piece of work, of which D is a portion, difficulty has (No model.)
been experienced in applying a turning-tool for the proper facing of the end of the work, owing to the limited space between the same and the inclined face of the center-piece B of the tail-stock. This difficulty I obviate by making a groove, a, in the conical portion of the center-piece. This groove in no way interferes with the functions of the center-piece,
while it affords an opportunity for the proper application of asubstantial turning-tool to the end of the work for facing the same, as will be readily understood by those skilled in the art of turning metals; andin chasing a threadon a pipe or rod the groove permits the tool to travel back clear of the work without coming in contact with the center-piece.
I claim as my inventionwhich is a groove, a, as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two sub- HARRY SMITH, HENRY Howson, Jr.
