To whom it may concern:

3e it :known that I, LEWIS H. MORGAN, 'a citizen of theUnited States, residing at Plainfield, in the county of Union and State of T 1. hew Jersey, have lnvented a new and useful Improvement in Quartering and TurningMachines for Crank-Pins and Eccentrics, of which the following is a specification It has heretofore been usual to form the shafts and cranks,especially for torpedo-boats and similar small vessels, from one casting suitably annealed and tempered' 'Some of these shafts are made with two cranks and others with three or four. It has heretofore been usual in shaping the shafts and cranks to turn the same in "ordinary eng-ine lathes This is a comparatively simple matter so far as the shaft itself is concerned; but great difficulty has heretofore been experiencedin turning the crank-pins of the said shaft, as it 'l1as been necessary to mount the same in a lathe andturrithe complete shaft and cranks aroundeach' crank-pin as a center, and in doing this great difficulty has arisen in so supportingthevarious parts as to prevent the same being turned untrue. -In fact, it hasbeen practically impossible heretofore to turn these crank pinstrue'for this reason; and my invention relatesto a machine adapted tov overcome these diiiiculties and in which ma' chine'the said crank-pins and the faces of the cranks are turnedand trued andv also in which eccentrics are turned and trned, the

machinein its functions alsolbeing capable of placing'with mathematical (accuracy the positions or quartering ofihe various cranks. In carrying out my invention I provide a main section-b preferably grooved, with.

three longitudinal ways forming slides, one being central of'the bed. Upon this bed I mount suitable rests that are in perfect alin'e ment and inwhich the' shaft to be operated upon is supported and to which it is securely clamped and fixed,and Lprovidean ad'justing-arm also clamped to the shaft' and the movement of which assists in quarteri-ng the crank-pins.

This quarterin'g'consistsi'n placing the sever'alcranlrs of av shaftin accurate. horizontal and vertical 'positions-thatis, if

there are two opposite cranks they are placed horizontal, if four cranks atqnarter-points two are placed horizontal and two vertical;

and if thereare three cranks one is placed hundred and twenty degrees-and the mechanism hereinafter described is capable of-fine and accurate adjustment for predetermined and calculatedposi tions,"so that all the various crank-pins or eccentrics of the shaft as held in the'supportscan .be operated upon progressively or collectively without once shifting the position of the. crank-shaft; I provide'one or more movable columns mounted upon a'movahle base, the said base having a longitudinal movement of the mainbed base, and I provide heads supported by the movablecolu nuns, and connected to 'eaehhead is a revolving cutter-ring, a path being prohas a-removable sectionand the cutter-ring pin to beturned can be'passedrthrough the opening formed in the head and ring'to the center of the same. The head is balanced i on the column by a counterweight, and I provide means for raising andlowering the head and means for supporting the same to overcome the efiect of any possible vibration". I also provide-means for rotating the cutterring byp'ower and means for moving the coluni-n transversely of the base and other means main bed.

Upon the main bed there may be several columns and bases and'cutter-rings and the mechanism for operatingthe same, and asthese parts will be duplicates of one another. the description hereinafter will only vertical and the other two inclined at one.

and the column a transverse movement-of the vided for the ring in the head. 'The'head relate to one complete device, the various also a removable section, so that the crankfor'moving;. the base longitudinally of the movable base for trans- F 7 8.a'n l 9 represent details of the mechanism and bolts pass through the caps and through the upper part of the rests to clamp the parts together and firmly hold the shaft as-supported by the rests. The lower ends'of these rests are adapted to fit in the central slideway of'the main bed, and they may be moved along the said central slideway to the desired places, where .they are clamped firmly in place by bolts. (Shown especially in Fig. 3;) In connection with these rests b I provide an adjusting-arm 1; with an upper end made similar to therests, to be clamped to the shaft a, and theflower portion of said rests,;at opposite sides,is provided with lugs and screws 1, and the said adjusting-awn maybe fastened at any desired point to the shaft, with its lower end brought between the adjustingscrews at either side of any rest, the object of the said adj usting-arm I) being to slightly swing the shaft a and its cranks and crankpins before these parts are firmly fastened,

1 so that the same may be brought into an accurate quartering position, this swinging movement being effected by the screws 1 as one is loosened and the other tightened from -either side.

The head d isfittedto slide vertically upon one face of the movable column e, the face of the column being made with a slideway and the edge of the head being provided with flanges or rollers, or both, in order to insure 'a close fit for the said head. This head is-made witha circular hollow extension to one side for receiving the revolving cutter-ring g. The said column a issupported upon a movable base f, there being suitable slideways between the base of the column e and the movable base f and at the lower edge of the movable base f in relation to the-bed c of the machine. A counterbalance sliding weight it is provided and adapted to move over the curved opposite side of the column e, and a chain 2 connects the head (I and the weight It. This chain 2 passes around and over sheaves 3 4 5, supported upon the upper end of the column 6, the sheave 4 being horizontal and the

sheaves

3 and 5 vertical and at right angles to one another, so as to form a path for the chain and compensate'for its direction of travel. 4

The head (land the cutter-ring g, carried thereby, are raised and lowered by a screwrod 6, which passes through the said head and throughtheslotted'portionof the column c, and at he upper end of said screwrod I provide a pair of bevel-wheels 7 and a hand-wheel 8 on the shaft of one of the bevelwheels. When this hand-wheel is turned and the bevel-wheels and the screw-rod rotated, the said head is raised and lowered, and no particular force is required, because freedom ance -weight.' The hollow extension of the head, and in-which the cutter-ring revolves, is provided with a removable section d,which of movement isinsured by the counterbah section is held in place by thebolt 11, and 1 thecutter-ring is also provided with a laterally-removable section g, and there are teeth 9 upon the periphery of the cutter-ring and its section, which teeth are engaged by a.

worm 10 on the screw-rod t. This screw-rod passes vertically through the head at, and the worm 10 is connected to the same by'a spline, so that the head can be raised and lowered with facility without disturbing the rod, its connection, however with the worm being maintained through the spline, Thereis on the lower end of the rod 1' a spiral gear-21 in a frame 20;" The said cutter-ring is preferably made with spokes and a central web connectingthe peripheral ring carrying the teethto an open hub or gap; A flanged on one side of the hollow extension to the head acts as a guide for the cutter-ring, and a ring t at the other side removably connected to the face of the hollow extension of the head forms 'a guide for the cutter-ring at the other side, so that the cutter-ring revolves between the 'flange d and the ring (1 The removable section g closes the entrance to the open hub of the cutter-ring, and in this por'tion slide-- ways are-made for the sliding tool-rest 7c, the same at its forward end carrying the tool- 'clamp 12; A screw-shaft 70 passes through nuts 13 in the sliding tool-rest 7c, and the said shaftk'has a worm-wheel'15 fixed on oneend andreceived in a hollow'portion of the removable section g, the said worm-wheelmeshing with a worm 14, the shaft of which is at right angles to the worm-wheel and pros rro jects from the said removable-section and 4 carries ,a small hand-wheeLGO, by which the said worm and worm-wheel are turned and with them the shaft 10'.- the shaft lo and-screws into the opening in the inner face of the removable section g.

A disk 16 surrounds The disk '16 is fixed in its position in relation to the removable section g by any desired mechanical-device, and'lock-nuts 17 are pro vided upon the screw-shaft k to take up any slack, so as to keep the worm-wheel l5 snugly against the face of the disk to prevent lost motion. The rotation of the worm 14 and worm-wheel '15 and the screw-shaft it move the sliding tool-rest 7c and feed the same with the tool carried thereby up to the work on '7 the crank-pin a and I provide push-rods 18, I

moving in openings in the cutter ring, and springs 19 in said J openings behind said pusher-rods, the same bearing against the opposite faces of thesliding tool-rest, so aste force the same backward, while the screw; shaft 7r forces the same forward, the QlJJ'QGt bein betweenthese two forces to maintain the sliding tool-rest positivelyin position, soj

that. the same will not shift or vary-asthe cutter-ring is revolvedand the crank-pin turned.

through a splitsleeve 35, formed as apart of the movable base f, the said post 34 having a head coming against the under-flat surface of the extension of the head at. vThis post is clamped by the screws passing through the split sleeve35. The post is to be adjusted immediately after the head (Z and the cutterringare brought to the exact position'desired and before the cutter-ring is revolved against the work, the object of the said post beingto' prevent any. possible vertical vibration incident tothe revolution of the cutter-ring and the altered position of the slidi-ngtool-rest therein as the same revolves around the crank-pin. v j

' The spiral gear 21 at the lower end of the a shaft 11 meshes with a spiral gear 22 also in the same frame and upon the shaft Z. (See Fig. 8.) The Opposite 'end of' the shaft Zis' provided with a hub l, on which is a gear 23, The gear 23 meshes with a gear 24 and a third gear 25, the gear 25 being on the same shaft as are the fast and loose pulleys 2 6 27. The power-belt 28 passes around the said fast or .the loose pulley and around a pulley 29 on a shaft 31 at oneend of'the bed of the machine,

and which shaft 81 carries the cone-pulleys m to which power is communicated at the desired speed. The beltat the other end of the main bed passes around an adjustable pulley 30 and beneath the loose pulleys 32 3 3. The belt 28," the pulleys 26 and 27, the gears 23, 2i, and 25, and the shaft Z are the power, devices not only for rotating thecutter-ring g, but for moving the base f longitudinally of the bed of themachi'ne and therewith car rying the column-sand the 'head (1 and the parts'c'onnected therewith, the said'pulleys 32 33, as well as the pulleys 26 27 and the gears 23 24 25, being connected to and supported from the movable base f, and {I provide a belt-shifter f for moving the belt between the fast and loose pulleys.

The transverse movement of the movable cdlumn e in relation to the movable base f is effected by the following devices: A slideway 36 is formed in the face of thesaid base, and the base of the column c" is made with a v threadedsleeve e, having nuts with which the screw-shaft 37 is in engagement; (See Fig.

. 7.) One end of the screw-shaft 37 passes through a bearing in the movable base f, and

on the end thereof is a gear 38, meshing with a gear 39 on the shaft of the hand-wheel 40. A dial 41 is mounted on the outer face of the gear 38,and a pointer 42,fasten ed.to the upper face of the base f, extends over the periphery of the gear 38, with the point thereof in proximity to the edge of the dial 41-, thus forming a Vernier to indicate to a nieety the extent to which the movable column e is transversely adjusted.-

I provide an adjustable post 34:, passing is provided with a'dovetailed way along which the head 0 is'adapted to be movedythe said The movable base f, provided with guides and moving inthe slideway in the surface of devices, or the same may be performed by hand-operated devices, as follows: The said devices are operated and shifted by hand by a ratchet-lever n, of ordinary construction, upon the upper end of a shaft passing vertically through a portion of the said base f, and at the lower end of the said base f and on the lower end of the said ratchet-lever shaft is a pin n, meshing with a rack 11 the raclcruuning lengthwise of the main bed upon one of the vertical faces of the slidewa'y, as will be seenmo're' particularly from Fig. 2. The pawl device'of this ratchet of usual construction may be operated in either direction to turn the pinion n and move the base f along upon the main bed 0, the disengagement of the pawl in the ratchet-lever permitting the pinion and its shaft to run free when the devices are otherwise operated.

The base of the longitudinal slideway in the 1 main bed c,along which the base f is moved,

head ohavinga dovetailed slide in the said way and bolts passing through the .head, Figs. 1,. 2, and 3, to clamp the said head immovably to the said bed. This head is loosened when it is-desired to move the base and the devices connected thereto and supported thereby 1ongitudinallyof the bed'by means of the-ratchetlever a, pinion 'l'L', and rack M, the said head being'always clamped rigidly to the bed-during the turning of a crank-pin andwhile the power devices are moving the cutter progressively along for turningthe said crank-pin.

The lead-screw shaft t passes through the head 0, and there are adjusting-nuts in the said head 0 similar to those in the threaded sleeve c of Fig. 7 for-the purpose of taking up slackor wear in the screw-shaft. This device is not new with me, but is made use of in this machine for the purpose of taking up all wear to obtain a fine adjustment of the parts. The lead-screw shaft t passes through the movable base f, and its end opposite to the head 0 is in a bearing'in the base of the yoke-frame standard 8, there being a gear 55 Joe on this end of the shaft 25 adjacent to its bearing, with a collar between the gear 55 and the standard and nuts on the outer screw-threaded end of the said shaft (see Fig. 11) for firmly connecting the said shaft'to the said stand-' ard, so that there will be no lo'stm'otion where power for moving this screw-shaft t is communieated throughythe belt 28' to the fast the shaft is connected to the standard. The

- to a. worm-wheel 46 to .the shaft of'a set of pull spline-gears (see Fig. 8,) and from them to a shaft 47, on which isa worm 48, the worm 48 meshing with a worm-wheel 49 on' the shaft 50. This shaft 50 passes through bearings in the base of the yoke-frame standard 's, and on said shaft, between the yokeframe, are small bevel-wheels '51 52, with a clutch s between the bevel-wheels, the said bevel wheels more properly surrounding sleeves connected .to the said shaft 50, and which sleeves have clutch-faces adapted to engage .with the faces of the clutch s, the said clutch 3 being operated by a hand-lever .9 (see Figs. and. 11,) the said hand-lever being pivoted to the face of the yoke-frame standard 8 and adapted to swing the clutch either to one side or the other, so as to engage either the bevel-wheel 51 or the bevel-wheel 52. The bevel-wheels 51 52 and the clutch: sleeves on which they are mounted are loose upon the said shaft 50, while the clutch s is connected to the shaft by a spline, the clutch always turning with the shaft and when in engagement with either clutch-sleeve causing the same and its bevel-wheel-also to rotate. The said bevel-wheels 51 52 are in engage ment with a larger bevel-wheel 53, mounted back of the shaft upon a short shaft in the base f. This bevel-wheel 53 is connected to i a gear 54, also on the same shaftback of the 3S bevel-wheel, the said gear v54 meshing with i fore-named gear on the-lead- $crew shaftt. H

The yoke-frame standard 3' is hollow, and a I shaft to passes vertically-through the' same.-

On the lower end of the shaft u is a bevelwheel 57, meshing with the, bevel-wheel 53,

and on the upper end of the said shaft u there is a small bevel-wheel, and adjacent thereto, on a horizontal shaft-connected to the said standard, is another bevel-wheel form ingthe pair of bevel-wheels 56, on the shaft of 'oneof, which is the hand-wheel u. The turning of thehand-wheel uoperates the pair of bevel-wheels 56, the shaft 11 ,-.the bevellead-screw-shaft t. t in thefixed head o'move's the base

57 and 53, and by the bevel-wheel 53 the

gears

54 and 55 are operatedtoturn the The rotation of the shaft 4 tud'inally .of'the bed 0, so as tofeed by hand and gear-s54 55, with the-sha the cutters-ring carried .on the movable column 6 upon the base f along, thecrank-pin' being turned bythe' tool carried by the revolving cutter-ring g. 1 A" hand-feed is thus of footed, or the said devices may be operated to bring the cutting-tool'to the correct startingpoint, so that the cutting movement is thereafter efie'etedby the power means hereinbeforedescribed.v With reference to these ,power devices it will be noticed that when the clutch sis in engagement with the clutch:

face and bevekwheel 52 the. bevelwheel 53 head (1.

are turned in one direction and that when the clutch s is in engagement with the clutch-face and bevel-wheel 51 the bevel-wheel 53, the gears 54 55, and the shaft 25 are turned in the opposite direction, thus providing for themovement in both directions along the bed 0 of the base f, the movable column 6, and the devices carried by the same. 7

Reference has hereinbefore been made to the Vernier device 41 42 in connection with the transverse movement of the column 6 upon the base f, and I also provide vernier' scales for devices 43 44, the Vernier 43 having its dial or scale on the base of the column (3 and its pointer on the base f and the'vernier44 having its scale on the upper vpart of the column 6 and its pointer on the vertically-moving These Vernier devices .make: possible not only a fine adjustment of the" parts in relation to one another, but make it possible to accurately and mathematically determine the correct quarterin g position for the cranks (1 upon the shafta. The same devices are also made use of in connection with the turning of eccentrics upon the shaft a adjacent to the crank-throws.

It will be evident in connection with the operation'of the machine that the main bed a of the machine may be of any desired length.

to receive a shaft a of any desired length having any number of crank-throws and also that upon the bed a I "may employ several complete turning devices, each comprisloo ing a base f, a column e, a revolving cutter- .ring, and all the attendant devices necessary tomove the said bed, the column, and re-- volve the cutter-ring, so that several of the crank-pins may be turned simultaneously;

In Fig. 2 I have illustrated by a plan view one complete operative device for turning one of the crank-pins, the same being shown. in. Fig. l in elevation, while on the opposite side of the bed in outline is shown the'position ofa similar turning device reversed.

Thus there may be .two or more complete devices on either side of the bed for simultanef ouslyefiectingthe' turning of the crank-pins or eccentrics.

I would further remark that it makes no difference with these devices whether the crank-pin be above the center of the shaft or below it or at either side of the shaft, because'the head d can be raised or lowered upon the column to bring the horizontal center of the cutter-ring tocoincide with the horizontal axial center of the crankpin to be turned, and thatthe transverse.

movement of the column 6 upon the base f will bring the vertical center of the cutterring to coincide with the vertical center of thecra'nk-pin to be turned,and'that the devices on' the oppositesides' of the bed are adapted to reach the crank -pins in theirposition above or below or at, either side of the center of the shaft, and I would further remark that the rests'b are to be so placed with reference tothe turning" of the crank-pins'or eccentries as to holdthe parts rigidly in position and provide room for the action of the I revolving cutter-ring. In its action the tool of the cutter-ring is not only adapted to turn the crank-pin so that its axial center may be parallel. with the axial center of the shaft, but so that the said crank-pin is absolutely true and cylindrical. The tool of the said cutter-ring is also adapted to turn the adjacent opposite faces of the crank-throws, also the faces and surfaces of eccentrics, the various movements of the base f, the column 6,

and the head (1 providing for determining the position for cutting and thevmove'ment of the sliding tool-rest 7c in the revolving cutter-ring, providing for the extent of radial movement from the cenlerof the object besame and their shaft, substantially. as set 2, The combination with the main bed having, a longitudinal slideway, of rests-fitting an movable in said slideway and adapted to receive and support the said crank-shaft, of clamps connected to the said rests for securing the shaft and an adj usting arm clamped tothe cranl' -shaft, and means for holding and-moving the same toslightly swing the shaft and bring the same into an accurate predetermined position, substantially as set forth. p p r 3.
