Description

waited tattt atletia @Wire i DANIEL KELLY, 0E PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIM- SELF AND WALTER K. LUDWIG, OE SAME PLAGE.
Letters Patent No. 100,772', dated March 15,1870.
nvrrnovnb cENTnRrNG-ATTACHMENT PoR LATHE.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom 'it may.conce-rn.:` A
Be it known that I, DANIL KELLY, of Philadelphia, in thecounty of Philadelphia, and State of Penusylvania, have invented a new` and improved Centering-Attachment to Lathes and vI do hereby declare that the following is' afull, clear, and exact description thereof, which will enable others skilled in the art to `make and'use the same, reference beinghad tov the accompanying drawing forming part of this specifica-v tion, in which- Figure 1 represents a longitudinal "section of` my improved centering-attachment.
Figure 2 is an endrvievlv of the same.
Similar letters of reference indicate corresponding parts.
This invention relates tocentering-attachments for drills, and` consists in an improvement thereon which will be specified hereinafter. A i l A, in `the drawing, represents the drill-socket, arranged in the revolvingxspindle of a lathe in the ordinary manner. l *y y B is thebit secured inthe drill-socket A.
Upon the drill-socket is loosely fitted a slide sleeve,
Y C, which has a funnel-shaped inner end, a, that embraces the end of Ath'ebit, as is clearly shown in iig. 1.
'Ihe sleeve can slide on the drill-socket.
A spring, D,bearing against the outer end of the sleeve, holds it forward on the spindle by acting on an adjustablecollar of the drill-socket.
It will be seen that when the end of a shaft or other article is fitted against the end of the bit, it will at the same time enter the funnel, and will in the same be centered and heldl so as long as the bit is in contact with the shaft, while, during the operation of drilling, the shaft orother article is fed forward, the sleeve `will gradually be forced outward, contracting the described, consisting of the socketed spindle A and sleeve C, having the perforated funnel a at one end and tubular enlargement and spring at the other, all
constructed and arranged as and for the purpose specified.
DANIEL KELLY. y
