f'o all whom it may con/cam:
Be it known that I, LOUIS Vii "Nnin', a citizen of the United States of America, and a resident of Waterlom Blackhawk county, Iowa, have invented certain new and useful Improvements in Devices for Turning Crank-Pins on Engine-Shafts, of which the following is 'a specification.
My invention relates to improvements in *devices for turning crank-pins on engineshafts, and the objectof my improvement is to provide means capable of use on an ordinary engine-lathe which will receive engine cranks of diilei'ing dimensions, and which may he used to turn the crank-pins thereof quickly, truly and with the proper finish and design. This object Ihave acconiplished by the IDGZlIlS WlllCl'l are hereinafter described and claimed and which are lllUS trated 1n the acconi mi 111 drawnws. in
Fwure l is an elevation of an en 'ineb v n I w lat-he equipped wlth my HIIPPOVQCl device for turning the crank-pin of an engine-- shaft. Fig. 2
is a slightly enlarged endelevation of the pair offending-tools used with my device. Fig. 3 is end-elevation in detail of the end of the journal-end holding-hotly which has the crank-arm clamping-means mounted thereon. Fig. l is sideelevation of said journal'end holdingbody, showing an engine-sh'aft journal-end i'eniovably secured in the seats therein.
Fi 5 is a similar view of said holdin n u body, the holding-body being turned one quarter around. 6 is a transverse sec ion of: said holding-body taken on t-he'line m as of Fig. 41 and looking toward the left. Fig. '7 is a transverse section of said holding-body taken on the line 1 y'of said Fig. 4.
v Similar numerals of reference designate corresponding parts throughout the several views. v
The. numeral 48 designates an'enginelathe on which niy improved device for turning the cranlepin of an engine-shaftis This device comprises a holding-hodv fer the journal-end of an engine crank-shaft, and cutting-devices an,
pi'opi'iate for turning the crank-pin of the shaft into a illle finished shape. The holding-lively comprises vertical spaced apart parallel disks 1 and 2, connected by integral parts setat. right-angles to each OtllBlQEiS shown at the Webs 3, 4, 5 and 6. Thevvehs Specificatimi of Letters Eat-ant,
eross-sectioin as best shown in l by means of bolts face of the disk 2 blocks 42 and 4:3, spaced aparthnd seemed 3 and lextend dia/ heads if 5; therehetseen, While heads are ollset a little pendicnlai'l v to the (l Webs 3 and at serve only to stroll holding-body, but the other well; -plied with similarly formed hm: di sized alined seatsl suitable to ltf journal-ends 0t crank-shafts of differing diameters. The seats in these Webs mav {i5 have hearings T and 1G. and S and. 522 respec tivelv, which may be either fixed or removable, and each hearingis trongh-shaped in igs. (land and 8 in '7. The hearings-7 in the web 5., the web 6, have cross-plates l]. and 1:? respecti\'ely, which are removahly secured over said hearings by leans oi": the screws 13 and 14; These cross-plates serve to se cure the journal-ends in the liieaiings, and 2 the journal-end is secured also hv means of a set sci-ew l0 seated in the Web and engaging it. 'lliehea1ing 8 has: a similar set-screw 9 for-a like purpose. The dial: 1 is bolted to the face-plate oi Sl lathe ,a i in n l; therewith. The Webs and 6 have right-hand ends similar ex mnsions and 20 respectively which contain hie hearines l6 and and set-screws l? and 21 respec- 8 lively serve to secure journal-ends in said bearings i-eniovahly.
The numeral 88 ClQSlf IHlGS a ring-hearing which surrounds the disk 2 and .i ill ilCQCl apart therefrom all around, and heme concave Within, contains hearing-liloclzs 3S) eqnidistantlv placed about said disk and adapted to bear against the edge of the latter. The bearing-blocks are moval'ile tward said disk and adios l by means: i set-screws %0 to properly center said dish. The clamping-means on the right-hand con'lpiises a pair of fixed to the disk by means of screw, the space 192 left: between sa d hlecltsheing il'licient not only to receive thei'chetWeencrank-pinarms of different widths, but also permit of some adjnetnient of said arms 25in bring 4 crank-pin into axial alincinent with said M15 holding-hotly on the lathe. The'nmncrals l l and L5 designate slidinghloclts movalialc in grooved seats in the fixed blocks 42 and 43, and Whose inner ends are oppositely located in alinement across the diainetei."
and d3 respectively against them. hen
the journal-end of a crank-shaft 523 has been passed into Whichever of'the trough-shamed openings in the disk which is fitted to re ceive i and then secured to said holding} body by the means described so that its crank-pin 24: is truly aiined with s-iid holdiiiigbody,'the climb-pin is in {L position suit able for rotation to be shaped truly into the required form by means of the following i'ibed cuttingdools and appliances.
ihe numeral 36 designates a base-block adopted to be mounted out-he lathe-frame to the righbhand of the ringbeering 3d, the latter being also mounted on said l2Ltl19 .rt'i-eine. The base-block 3'3 edjustably supports a body upon which are trzuisversely spaced apart uprights 28 and 29 secure to it by bolts 33 and respectively. The upriglit 28 has on its inner face a cutter-tool 26 seem-ed thereon adjustably by means of adjustin'g screws 30 and 31. The other upright 29 has a, outter-tool 27 secured on its inner fece adjustably by means of an adjustingscrew 32. Spindle-arms 37 may be used to adjust the position of said ports transversel oh the lathe-bed. When the tool 26 is use ifgives a rough-cut to the crank-pin 24;, and this operation succeeded by the use oi the cut-ting'tool 27 Which finishes the crank-pin tothe smooth desired form,
The said device accurately performs the ,i'equii'ed duty in a minimum time, and perfects the crank-pins with a great saving of labor.
it is t be linderstood that variations of said device'ere covered by the scope of and incldded Within the principle of this invenlion-".7 v i I. v
