Letters Patent No. 80,840, dated August 11, 1868.
IMPROVBD SCREW-CUTTING MACHINE.
TO ALL WIIOM IT MAY GONCERN v A Be it known that I, VINZENZ SMITH, of Middlebury, in the county of Summit, and State of Ohio, have invented certain new and useful Improvements' in Screw-Cutting Machines; and I do hereby declare that the following isa full and-complete description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a siderview of the machine.
Figure 2 is a view'of the top. i
Figures 3 and 4, detached sections. V l
Like letters of reference refer to likeparts in the several views. I
In iig. 1, A represents a bed, on which are erected the standards B Br. v In said, standards is tted a hollow shaft, C, having a thread cut upon its outer end, which is screwed into the standard B', vwhereas the opposite end is fitted so as to work freely in .the standard B. is a hand-wheel, whereby said shaft C is turned, for a purpose hereafter shown.
In the hollow of th'e shaft C is loosely fitted a shaft, indicated by the dotted lines a. To the inner, end of this shaft is fitted, and secured, by means of the screwsb, a. socket, F. On the inner end of said socket is a screw-plate, G, iig. 3, in which are fitted the dies H for cutting the thread on bolts;4 I, fig. I, is an adjustable standard, secured to the vbase or bed by a bolt, C, tted to and working in a slot cut in the bed for that purpose, To this adjustable-standard is attached a stay, J, in which is fitted apair of blank-dies, K, iig. 4.
The practical operation of thismachinc is as follows:
The bolt to be cut is insertedin the blank-dies K, and therein secured by screwing the dies together bythe set-screws K', as shownrin gs.-1 and 2, in which A represents said bolt.V The end ofthe bolt is then inserted injthe lscrew-dies H, and a thread thereon out by turning said dies by means of the crank B. As the dies are beingturned, the bolt is fed to them bythe adjustable standard being drawn forward toward them, it being loosely fitted and secured to the bed. In order to cut the nut for the bolt, thescrew-dies H are removed, and replaced by blank ones. In Said blank-dies the tap is held, whereas the nut is held in the diesK, as was the bolt. AThe tap is now inserted in the nut, and the thread eut therein by turning the shaft and socket, as before, for the bolt, the nut being fed to the tap by the moving forward oi" the standard, in whieh'it iss4 secured.
By this apparatus, boltsl and nuts are `readily and easilycut, requiring n extra machinery for that purpose, thel ordinary h and-drill, in common use in blacksmith-shops, being thus readily converted into a screwcuttingmachine, by'simply attaching the socketl to the drill-shaft of the machine, and attaching the stay J and dies to the standard, which latter may be allowed to remain attached to the standard as a permanent xture, as it will not be in the way when using the machine for drilling. ,I
The combination of mechanismfherein described, for cutting screw-threads on bolts, snuts, Lite., I do not claim; but
Modifying the structure of the parts of said combination, and combining with said combination the several devices, in virtue of which Ithe apparatus may be used as a drilling-machine, aswell as a bolt and nut-:threading machine, all substantially as described and shown. Y
' VINZEN Z SMITH.
