IMPROVEMENT IN WOOD-TURNING LATHES.
diluir Sunnah nana tn' in tina ninas hneln ma takin aan nfiln sana.
TO ALL WHOM IT MAY CONCER:
Be it known that I, DAVID Dien, of Corning, in the county ot'- Steuben, and State of New York, have invented a new and improved Machine for Turning Spools, Bobbins, Sie.; and that vthe following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and enact specification ofthe same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished from all ot'hers of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent. f
Thisinvention relates to a new vand improved machine forturning spools, bobbins, and other wooden articles of a similar kind.
The invention relates to a means for operating wreck-shaft and the slidingl bar of one of the heads of the lathe, whereby motion is given to two reciprocating tool-slides ina direction towards and from each other, and the sliding bar moved to release the finished spool Aor bobbin, and to feed the sticks to the lathe. I
This invention pertains to a machine of the class above specified, and is a modification of a means for a similar purpose shown on said machine, and which, consequently, is the subject of a separate application for Letters Patent.
In the accompanying sheet' of drawings-'- Figure 1 is an end view of my invention, t'
Figure 2 a plan or top view of the same,
Figure 3 an end view of a modication of the same, and
Figure 4 a. side view of iig. 3.
Similar letters of reference indicate corresponding parts.
A represents the head of a lathe, and the sliding bar thereof, the other head, with its rotary mandrel, being shown in red in fig. 2. l
C is a rock-shaft, which gives a. reciprocating movementto the tool-slides a a of the-lathe, said slides moving towards and from each other simultaneously, so that the tools which areattached to themvmay act( upon the 'Y work secured between the centre-points ofthe lathe, the rock-shaft having adoubl'e crank, b, secured to one end ofit, the ends of which are connected by rods c e to the tool-slides, as shown in red in iig. 1.
The oppositoend of the rock-shaft C has an arm, D, keyed or otlieiwisesecured upon it, -saidarm extending from opposite sides of the shaft C, and having a weight, E, on oneend, and to said arm, at the opposite sideof the rock-shaft, there is attached an oblong loop, F,-at right angles with thearm. A
The extreme end of the arm D,.which has the loop F attached, has a lever, G, attached by a fulcrum-piu, d, one end of said lever workingin the loop or guide F, and passing through a slightly-curved and pendentv slotted arm, II, secured to the vouter` en d of the sliding. bar B. i
By this arrangement it will be seen that the roch-'shaft C will be operated by working the lever G in a vertical plane, and the sliding bar B, ofthe head .A, operated by working said lever in alateral direction. The weight E facilitates the manipulation of the leverr in the working of the rockQshaft.
The sliding bar B is moved laterally in order to release the finished spools'or bobbins, and -also. to feed the sticks to the latter, the particular apparatus for which forms the subject-matter for 'a's'eparate application.
The lever G, at the point where it works in the arm H, is mortised, and a pivoted block, e, is tted in said mortis'e, in order to avoid friction in the lateral movement of the lever Gr.
A modification of the above-described device is shown in gs. 3 and 4. Instead of the arm D andlever G, alever, I, is employed, the latterbeing attached tothe rock-shaft C, and having aweight, J, attached, while, at the handle-end of the lever, there is attached a segment arm, vK, which 'has a lateral curve, to serve as `a cam. This arm or cam works between pins,j`f, attached to the sliding bar B, and it will be seen that precisely the same result is produced by the last-described arrangement as by the one first described.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The weighted lever D, provided wththe Slotted arm F, inrwhich the end of the lever G \voxks,-sziid lever adapted to operatevthe ourved armrH, as herein describedywhereby the tool-heads and spindle are operated simulteneously, es mid for the purpose specified.' i l 2. The weighted lever vI, attached to theroek-sllaft C, and provided with the segment-arm K fitting in the spindle B, all Qpem'ting as described for the pilrposespeeilied.
