-To 4ALL `wHoM-1T MAY ooNeEnN:

Be it known that I, JOHN J. RALYA, of Allegheny City, in the county of Allegheny, and State cf Penn.

Sylvania, have invented a new and useful Improvement in Power Stavo-Dresser;- and I. do hereby declare the followingto bc a full, clear, and exact description thereof, reference being had to the accompanying drawings,

' making a part of this specification, in which- Figure 2 is c top er plan view of certain devices used in the head-stock for the purpose of regulating the action of thecutters, and

' Figures 3 and -i illustrate by side elevation the action of the rack and pinion in producing a reciprocating motion in the ram.

Like letters oi' reference indicate like parts. The natureof my inventionA consists in the construction and arrangement of devices for operating n. movable pinion, in connection with a toothed rack of estava-dressing machine, for the purpose of imparting a reciproeating or back-,and-forward motion to the ram', and in an improved construction of the head.

To enable others skillcdin the art to make and use my invention, Iwill proceed to describe its construction and mode of operation.

. On the framework aor other convenient foundation, rests the apparatus which I employ. b is the headd i stock, carrying cutters or knives c,`and constructed and operating as hereinafter to be explained. d `is a ram mov'- ing backward and forward on the slides e, and with its forward movement driving a stave resting against its head or end d endways between the ,cutters c c. To this ramd a cord, band, or chain, t', is attached, which passes t i through a. slot, t", inthe pulley-post f, and over a pulley-wheel o, and carries a weight, g, sudicicntly heavy to cause the return Astroke or back movement of the ram d. Thelower face of the ram d may be grooved, furrowed,

ianged, or shouldered, or operate between guides to secure a direct motion, or projections tmay be used for` the samepurpose. The motion requisite for operating the machine is communcatedin any ordinary wey, but as shown in the drawings, by a hand-wheel, Z, and throughl the gea1wheels`mm to the axlen, which carries a pinion, n', and which latter gears into a toothed rack 0, attached to the ram d, to produce the forward motion l of the ram, and ungears at the end4 of the stroke to allow the lram dto slide back preparatory to another stroke. `To secure this movement the end ofthejaxle n, near which the pinion n is attached, plays in a swinging bar, rr ,Q

which has sufficient vertical motion to gear `and ungear the pinion n and toothed rack o. Ih fig. 3 they `are shown ungearcdand' the ram d drawn back. To throw them into gear, the foot ci"l the operator may be placed on the outer end oi the lever s, and by the application of a moderate pressure the tripper s' is caused to raise.

the swinging bar r', and with it the pinion n', till the vlatter gears into the toothed rack o', as shown in iig.V

The post x, notched or shoulderedas at z', receives the end of the swinging bar mand, being braced by a spring, y, or held in position by an elastic band, y', or by other form of spring, or byweight and cord, supports the bar. 1' till the ram d completes its forward stroke. A pin or lug, e, attached to the ram dftheu strikes the post x, forces it back, releases the bar r, which drops, whereby the pinion n and'rack o arcungeared, and the ram is i carried back by the weighty. Another forwardA motion is then produced, as above described, another stave driven through between the cutters c c, and the motion continued forward and back, as above described.

.As ,the wear on the head'cil of the ram al is considerable, it is liable to be worn olii To meet such exigcncyl `1 I attach the pin or luge to. a cross-headH or plate,which operates in the slot e', and is h eld inplace at any i desirable point of adjustment/byA a set-screw. As the head d wears off the lug z may be set back lin its slot a', .i The rack o in such case should extend back `toward thepulley-post fn distance corresponding to the range` desired for such adjustment.

With the head-stocks heretofore in use it has been found somewhat 'diihcult to adapt the action of thc cut i ters c c to the sinuosities or crookedness of the stares; Such result has generally been securediby Vsetting the.

knives or cutters e c on journals c', which could be turned either way, as occasion might require, by a crank attached thereto. This necessitated a considerable exertion on the part of the operator, and was quite wearisome. To control the knives oiV cutters c a more easily, I attach to one of the journals a', which carries them,` a rigid arm, e', and by` the springs c, one on each side, allow for any necessary vibration of the cutters from side to side, and still apply any desirable amount of pressure, according to tire stiffness of the 'sp1-ings, to Akeep them in that .position in which they will most properly receive and dress the staves forced in as abcve described. The arm e is turned upward, near its rear end, so as to pass through or back of the cap-plate b of the headstocl where it is attached to or connected with a lever, u, of any desirable construction, pivoted tc the cap-plate b.

With this arrangement the operator canv easily, and without weariness, control the direction of the knives, as the staves are forced through by the action oi the rznnl.i n

What I claim as my invention, and desire to secure by Letters Patent, iis- 1. A swinging bar,r, in a stave-dressing machine, carrying a pinion to operate in connection with a toothed rack attached to the ram, in combination with a support, fr, to holdithe pinion in gear, and trippcr s and pin z to throw it in and out of gear respectively, or their mechanical equivalents, substantially as above set forth.

2. Adapting the direction ofthe action of the knives of a stave-dresser to the crookedness of the staves by a lever, u, attached to the head-stock, in combination 'with a rigid arm, e', attached to the journal which carries the knives, and with orwitlicut thc springs e, substantially as and for thepurposes above set forth.

In testimony whereof I, thc said JOHN J. RALYA, have hereunto set my hand.

JOHN J. RALYA.
