To lALL ,WHoM 1r MAY ooNcERN:

Beit known that I, E.` QUINLAN, of Sheboygan Falls, in the county of Sheboygan, andState of Wisconsin, have invented a new and useful Improvement in Burnishing-Mandrels; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, `V

Figure 1 is a frontelevation of my mandrel.l

Figure 2 is-,a side elevation of' the same. Y

Figure 3 is a vertical longitudinal section of the same.

My invention relates to a machine for finishing the surface ,of straight, or'nearly straight, turned work, such as rake-handles, fork-handles, broom-handles, dto., and it consists in a. hollow mandrel, having steel or other burnishers attached, and'so located that, as the work passes through the mandrel, the hurnishers will press upon its surface and reduce the same to a tine smoothness, highly desirable, and n'ot to .be attained in any other way.

That others may understand the construction of my apparatus, I will fully destribeit.` l A is a hollow mandrel, set in headlblocks B, and rotated with' great rapidityby some `convenient: means,las by a belt to a pulley upon aV revolving shaft, if used in a'shop where power is employed. The4 mandrel A has at one end a bell-mouth, as shown. in figs. 1 and' 3, to facilitate the entering of the work. Immediately behind the head in which isl the bell-mouth, a portion of the mandrel is cut away on eachofv two opposite sides, Sudicient to expose the hollow in the mandrel, andfrnm each'ofthe remaining opposite sides, between the o'rices above referred to, are projected short arms or studs C C, to the outer endsv of which areattached the springs D D, which I prefer to employ'to produce the requisite frictional pressure upon the burnishersl. The burnishers may be `of steel, and form parts ofthe springsiD, or theyrmay be madeofany of the well-known substances suitable for that purpose, and attached to the springs by some convenient means.

I am aware that hollow'mandrels have been employed to hold cutters for the productionof cylindrical forms, as in turning rake-handles, 56e., and I therefore do 'not claim anything as: to the hollow mandrel alone, but only in connection with `burnishers to finish the surfaces as left by the cutters, and I do not wish to be understood as confiningvmyself to the particular details of construction shown, because the construction may I be varied, especially to adapt the apparatus to one particular line of work, and so long as a revolving motion should be applied to polish byi'riction,l or burnishing of turned work of the character mentioned, I should consider it as substantially my invention. y I

Having deseribedmy invention, what I claim as new, is-' A hollow mandrel, A, with the burnishers D D attached thereto, substantially as and for the purpose set forth.

E. QUINLAN.
