IMPROVEMENT IN WOOD-TRNING LATHE The Schedule referred to in these Letters Patent and making part of the same www4- Toall whom it nml/concern:
Be it known that I, JAMES CHASE, of Rochester,
in the county of Monroe, and State of New York,4
` block G and connected parts.
Figure 3 is a transverse section, showing those parts to the left of the dotted line x, fig. l.
Figure 4. is a similar section, showing those portions to the right of the dotted line y, iig. 1.
Figure 5 is a vertical central section ofthe tailblock B. i
Figure 6 -is an inverted view ot' a` portion of my invention, representing the manner of securing the tailblo'ck.`
` Figures 7 and 8 are details. The object of my invention is to provide an automatic machine for turning all kinds of ornamental circular work used in furniture and other articles; and
'Its natme will be understood by reference to the specification and drawings.
To enable` others to make and use my invention, I will describe its construction and operation.
Upon the horizontal bed AI provide the head or spindle-bloeit" O and 'tail-block B, arranged similarly v to an ordinarylathe.
The slide-rest D is fitted to move easily upon the waysjof the bed A, and when in operation, is driven by the feed-screw a by means of the shear-nut b, iigs.
1, 3, and 4. r i
Levers c and dare cast upon the two. parts of the nut, which are pivoted to the slide-rest.
` The spring e, acting upon the upper end of these levers, holds the nut out of gear, as shown in g. 3.
'lhe cam y,attached tothe lever y by 'means of a spindle, having bearings in a suitable portion of the slide-rest, separates the levers and throws the nut into gear, as shown in fig. 4.
' lhe feedscrew is driven by any convenient arrangement of gearing or belts from the'main spindle C.
In the stock h, figs. 17 3, and4 4, properly secured to the slide-rest, I` fasten a roughing-tool, h', which rev, duces the stick to a circular form previously to its entering the die `or rest E. This tool is so adjusted that the stick shalljust fit the rest E, wherebyV it is prevented from chattering or springing by the ac-` tion of the nishing-knives. The rest E is made detachable from its stock, and may be replaced by others of different diameters. o
`For finishing the work, I use either the rotary pattern-knife F, figs. 1, 3, and 4, its shaft running in proper bearingsupon the slide-rest, and operated by means4 of the pinion fi meshing into the xed rack H, or thc-plvoted `rolling tool G.
The rotary pattern-knife shaft is controlled in its vertical movement b y a pattern, F', and its inner end runs in a pivoted box, as fully described in my patent of March 26, 1867. o i l lhe rack 1-1 is longitudinally adj ustable inthe swinging arms H', and is scoured by the clamping-screwsj', by means of which`any adjustment of the patternknife to a particular point in the work, less than the pitch of one tooth of the pinion i, may lbe obtained by loosening the screws j', turningV the pattern-knife to the required point while the slide-rest remains stationary, or vice versa, and clamping the rack again.
Parts L, figs. 1, 2, and 3, cast or otherwise secured i to the head and tail-blocks, and having their inner faces perpendicular to the ways ofthe lathe, guide the pivoted arms H', whereby all end motion caused by the thrust of the carriage' and pattern-knife is prevented.
lhe stock G of the finishing-knife G is fitted to turn in the box I, at right angles or nearly so tov the work, and this box kis pivoted to the slide-rest at the point n, iigsgl, 3, and 4, parallel or nearly so with the work. The knife G is thus permitted a rolling movement in the box I, and a vertical movement about the center n. w i These movements are controlled by the patterns o andl p, secured to the be-ni J, as shown in iig. 2, whereby the finished work will be anexact copy oi' the outline of the rear pattern o by means of the arm q rest-ingoupon it and secured to the tool-stock G', and the knife G is rolled to prevent gouging when moving over curves or inclines, by means-ofy the bent arm q', secured to q, and resting upon the pattern p.
The oice of the tool G is chiefly to nish the lplain curves anti tapers in the work(y acting in connection with the rotary pattern-knife F', which executes the sharp and more diiiicult portions. This is an important feature in my invention, since I am enabled to use the inexpensive knife G, which is easily kept in order for a large portion of the work, whereas,.the pattern-knife F is both costly in construction and difticult to sharpen, audits use is not necessary except upon the more intricate curves and ornaments.
The patterns o, p, and Fare consequently so formed. and adj usted with relation to each other that at the moment the pattern-knife F drops away from the work, the knife G descends and begins to operate, and 'vice fversa.
The beam J figs. 1, 2, 3, and 4, made longitudinally adjustable upon suitable lugs cast upon the head and tail-blocks B and C, as shown more clearly in iig.
