dma- IMPROVEMENT IN ARBOR FOR TURING- CLOTHES-PIN S.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Beit known that we, BENJAMIN BROOKS Ocknr'e- TON and ANDREW J OCKINGTON, of Stratford, in the county of Coos and State of New Hampshire, have invented a new and improved Arbor for Turning Clothes-Pins; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to' make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvements in machinery for turning clothes-pins, and consistsin a hollow arbor with rcughing-cuttersat one end for reducing the stick fed in thereat, and with a finishing and heading-cutter, arranged ina longitudinal slot in the side of the arbor, and provided with a spring to cause it to act on the stick, and a sliding wedge to throw the knife up for the discharge of the pin, when finished, said wedge corresponding in form with a recess or notch in the cutter-stock, and fitting or resting in the same while the cutter is performing its cttice, all as hereinafter set forth.

Figure 1 is a transverse section of our improved arbor, and

Figure 2 is a horizontal section of 'the same, taken on the line x x of Iig. 1.

Similar letters of reference indicate corresponding parts.

A is the hollow arbor, provided with journals B and C, to be arranged in boxes for rotation.

D represents roughing or reducing-cutters at one end, where the stick is fed into the: axial hole to be turned, the said stick being prevented from revolving.

E is a finishing-cutter, about the length ofthe pins to be made.

The edge is arranged in outline, to agree with the required outline of the pins. It is mountedon a stock,

F, held in a slot, G, in one side of the arbor, by pivots,

H, one at each end, borne in supports carried by the arbor, so that the edge will acton the partially finished stick lying in the axial bore of the arbor.

The stock F has a spring, I, attached to it at one end, and bearing on the arbor at the other, so as to press the edge down upon the stick with the requisite force to cause it to perform the necessary cutting to finish it to the size and shape-required.

The stock F has a notch in the back, with an iuclined wall, K.

A sliding bar, L, is arranged in the slot behind the stock F, and has an inclined projection which stands in front of the uotch'when the spring is forcing the cutter down upon and permits the cutter to act, but, Awhen the cutting is Iinished, the bar L is causedy to slide along, so that the projection M passes beyond the notch, and forces the cutter up away frontthe stick, to permit the finished part to be moved forward and another part to take its place, to be nished in like manner, the cutter `being permitted vto act upon it by moving the slide back.

For sliding this bar L, a sliding ring, N, is placed ori areduced part, O, of` the arbor, to have a crotched hand-leveror other device connected to it in any of .the well-known ways, for sliding it back and forth while revolving.

rlhis apparatus is intended .mainly for turning pins with heads on one end, or with other like configuration of the outline, requiring the cutter to be moved away while the inishedpart of the stick is moved alone.

'Wine are aware of a patent, granted October 8, 1867, No. 69,543, to H. T. Clay, for a lathe for turning broom-handles, 85C., in which is shown a certain arrangement of wedge and cutter, for opera-ting in a manner substantially,l analogous to those described in our invention; but we claim nothing therein shown.

.Having thus described our invention,

y NVhat we claim as new, and desire to secure by Letters Patent, is

The arrangement of the longitudinally slot-ted arbor lA, provided with journals B C, the roughing-cutters D, ring N, sliding bar L having projections M, pivoted stock F having notch K, knife E, and spring I, all constructed andoperating as shown and described.
