Description

IMPR'ovED PLANING-MACHN'R *says- The Schedule referred to in these Letters Patent and making part of the name oall whom 'it nul-y concern:
Be it knownthat I SETH Wrmlsn'rn, of Maiden, in
the county of Middle-sox, and Stat'eof Massachusetts, have invented certain improvements imPlaning-lf'ia-- chins, of which the following is afull, clear, and ex' act description, reference-being had to thc'aecompany- ,nying drawings, making part of this specification, in whioh--K- l -`Figure 1 is a perspective view of a planing-'machine with my improvements applied thereto. Y
Figure 2 is a side elevatian of the same. f Figurev .is a vertical section onthe linexxof fig. 2,
1u machines for planing metal, as heretofore constructed, the work, after being securely placed in its desiredlposition upon the platen, is moved, in comm'on therewith, in a longitudinal direction, under and against a toch-or cutter, which is held stationary while. thexwork is'being moved, after which Athe tool is fed'by a screw transversely across it a.distan`ce equal to the widthy oftA the too'i,-to' make a new cut; Where the casting to bev p la'nd is large and heavy, considerable power is required to moveit; vrAgain, where numerous projections and recesses are formed, it is impossible to obtain laccess .to their surfaces without frequently turning the casting, to bring kto the upper side the surface to be plancd; v
To remove the above-mentioned dii'culties is the object of my invention, which'consists in a tool-holder, placed at right angles to the plane oi' the ordinary `tool-holder, the tool in -tlie former being moved' transversely across the work, which is held stationary while tooll is moving, the power employed for driving the to'ol the screw usually employed for feedingthe ordinary tool, and the work is' fed by the screw usually employed as theppowrfscreiw, by which cnstruc-- tion it will be seen that lesspower is required to move -the tool` transversely across 'the stationary work than rto move the work longitudinally against a stationary tool, and the necessity of frequently turning the casting, to allow of" its vaiioussnrfaces being adjusted to the position ofthe tool is thereby dispensed' with.
To enable others skilled, in the' art to understand and use my invention, I will proceed to describe the lmanner in which :I have carried it out.
' In'tlie said drawingsn Al is the li'ameswork, in suitable dovetailed guides or ways a, in the top-of which moves the bed,or.`
fplaten B, the power for moving the same consisting ofthe ordinary horizontal screw-shaft C, passing longitudinally across the centre ofthe machine, and through a lug projecting, down from the -ceutre of the platen inra well-Ilmowrlv manner.- l,
On standards D, rising y.from opposite s ides'of the frame,-worli,y acrossbar, E, is made to slide npyand -dowrrhy bevel-gear cc, onY ,opposite ends. of a hori` @tai-Shaft- F, engaging with and, driving vsimilar beveigear d' ci," secured to the tops of two upright screwsG G, which pass through lugs con the back side oi' eachend ot'thc cross-har. (Sec figs; 1 and 2.)
H is a screw-shaft, passing longitudinally across thc centre of the cross-bar E, having its bearings therein at'f. Ono end ol' this screw-shaft extends beyond its bearing, and is provided witha.bevel-fear, (1, which is driven by a bevelgear, h, on. a vertical shaft, I, which revolves inA bearings fi, within or projecting iioin the sides ofthe framework.
The lower end of the vertical shaft carries a bevelgear, Il', which is driven by a correspondinggear, l, on one end of a horizontal driving-shaft, K, which niay be revolved by hand or by power, transmitted through. suitable connections from the main screw-shaft G.' p The screw-shaft H, extending longitudinally across the centre o'f the cross-bar E,passes through the back' of an ordinary sliding cross-head, L, which is moved along upon the eross-`bar vE, for thep'urpose of feeding the tool-'holder W and4 its .tool n laterally over the work on the plate11,-wlien the work has finished its longitudinal transit, under the tool, preparatory to having a fresh cut made thereon, in'a\vel l-kuown manner.
It will be seen .from the foregoing that the tool 'at is stationary during the operation o planing, and that the work on the platen moves longitudinallyunder the tool, the main screw-shaft() serving as a power for moving the work while the` screw-shaft serves toperiodieally feed the tool a successive distances, each equal to the width of the cut previously made, or that ofthe planing-tool; Y l' I will now particularly describe the construction and opera-tion of the mechanism which forms the feature of my invention, l v
'lhefslidnig cross-head L, which carries the toolholder-` VV, is bent-,around at right angles, as seen iu L. iig. l. Upon the 'portion o of this sliding cross-head is L,
formed a pair ol' vertical Vdovetailed guides, g), upon which aslide, g, is made tomove by tuini'ng 'a crank, r, attached to the upper end of a screw, 5;
Tov the slide q is pivotcd the centre of a crossfhead, N, which carries atool-holder, O, adjustable by means of a screw, 6, which `causes itto slide therein, and the tool-'holder Q carries atool, s, which is capable of being l adjusted therein by operating a series et'iscrew-nuts,
by which construction the tool' beswung around the entire cirenmiifrence of a circle', and bo secured atl any desiredangle, and in any desired position; l,
, yWhen a' heavy casting of irregular shape, and pro'-v vided wtlla n nmhcr of projections and recesses, is to he planed, the power required to ,carry it and the f platen longitudinally, undef' a stationary 1tool simi; lar to n; is rely considerable, and much time andlabor are consiined in Vconstantly turning over the casting to present its' surfaces properly toV the stationary tool; beside which there are sonic situations where the statinary` tool could not operate, -for instance, Where the verticalfaee of a piece of metal isfto be pinned, as the work' would soon come in Contact with the crosshar, oec-anse the tooln could not he fed down but a short distance in the tool-holder, without having la weak and insufficient bearing therein, which would thus e use it to chatter; mareover;'the, ozosslar E cannot he fed down l ut5"a"slxort distant .before theanorli would come in montant therewith By means ofmyimprovemente, screw H (ordinarily used tofeed' the tool oz.) ora-Slightly larger size, it'xnay be employed as `the power-screw for moving the tool s transversely across the work se YenredYA to the platen, when station-ary, the main screw C' ordinarily used" asY the power for moving the platen andwork, and -Imay serve as the'feeilor the movableY tool s.
When the vert-ical face of n casting-is to be 'pinned by my inovahletool, the oasting'isseoured upon the platen, andthe ytool-holder' is sivivell'ed around to the desired angie, after ,rwhieh the tool is run ont horizontally to the point on the face of the casting where the planing-operation is to emninenCe, when-it .will be Y neen that nothing prevent-s the eross-`oar from going down to the topiof'the platen, and allowing the tool to plane the lower edge ofthe work resting thereon, and
by movin-g the tool ont hy turning the screw 6,- I ein enabled to pinne the entire vertical .surface of an upnosts I).
right piece equal to 'the height of the standards, orr
To pinne the underside of a'large casting, partially revolve the tool-holder'L, so as to tnrn it., with its.`- tool n, ont of the way, when the 4tool-holderO is turned by the screw 6, up tothe top of'A the slide, or rest g, .and the crank r is removed, after which the cross-bar aid tool-holder O are run nearly down to the upper side i the platen i en the Work is supported on four standards, the tool s. readily travel back and forth upon the unl and hy making .the i enorm der siiriiee,y the lmain power-screw serving as the feed# screw 'for simply moving the work periodically a. distance equal to .the width of the out', or that of the tool;
Where the snrihees of the valve-ports of a steam" eylinoer are raised above the 'nearing of the steam- .chester-.bonnen after planing o the upper surface,
and twaof'the opposite yaides of the eatoi' the. eteamohesi., `with either tool, the other tool may be employed io:- plunmgj the oihertwo sides ofthe seat, or hearing, ywhich is below the .surface ofthe valve-seat; thatlis to say, I am enabled to plane all around van elevated centre without moving the work, which operations cannot he performed' by the use of the planing-tool, as
ordinarily constructed and arranged.
From the foregoing it vvill be seen that the time and -ln-oor necessary in moving the casting, and the neeessity of frequently adjusting it to the proper level, (incidentto ordinary planing-machines are avoided, and much of the power required to effect the planing-op'- eration is dispensed with, as it is easier to move the tool than the work While planing.
. v Claims. W'hat I olaiinns myinvention', and desire to secure hyLet-t'ers Patent, is,-
i. vIn combination with the cross-bar E, the crossheads L and 0, standing at right angles to each other,
and the vtool-holders W and N, substantially as described. Y.
2. The shaft K, with its bevelled gearing l, and the .vertical shaft I, with its gearing h k, in `combination with the screw H, for working either or -both of the cross-heads L and O, standing at right angles to each other, substantially as set forth.
