IMPROVEMENT IN MACHINES FR TURNING CARRiAGEHAXLES.
Specification forming part ofLetters Patent No. ll't'e', dated February 17,1874 application tiled l November 1, 1873.
To all whom 'it may concern Beit known that we, Hnoron MoKnNzIE and THOMAS COULTER, of Bridgeport, in the county of Fairiield and State of Connecticut, have jointly' invented certain Improvements in Machines for Making Carriage-Axles, of which the following is a specification:
The object of our invention is to facilitate the manufacture of wagon orearriage axles, and to make the same more uniform as regards their tit of the box, and to a standard gage, so that there will be no difficulty in replacing a breken axle without the box. The invention consists in various combinations, in the one machine, of certain mechanical de# vices and peculiarities in their construction, whereby the axle is centered and its bearing portion turned to the required shape and tinished 5 also its collar and shoulder formed and serewthread cut on its end, and the axle genorally completed, read y for dressing or finishing when hardened; all of which operations are performed by the one machine, and with out removing it therefrom, thus doing away with much handling, the usual iiling, and labor consequent on a succession of operations inthe ordinary method of manufacturing axles.
ln the accompanying drawings, which form part of this specification, Figure 1 represents a plan of a machine embracing my improve-Y ments, Fig. 2, a vert-ical longitudinal section of the same on the line .r .r, Fig. 3, a vertical transverse section on the line y y,- Fig. et, an end view, in part, of the tool-carrier, with tools attached; Fig. 5, a transverse sec-tion through a portion of the tool-holder, in illustration of the roughening-tools; and Fig. G, a longitudinal view ofthe axle or haltaxlc as it comes from the machine.
Similar letters of reference indicate corre spending parts.
A is the bed or shears of the machine, carrying a head-stock, B, a longitudinal toolfcar- Y The headstock B is fitted with a hollow revolving mandrel, the forward end of which has a jawed chuck, nE, that receives within it, and serves to hold by its jaws, a thimble, F, provided with any number of set-screws, I), for clamping t-he shank of the axle Gr, which is entered within or through the thimble and mandrel.
where it is held by the jaws of the chuck E,
constituting a ball-joint, c, to facilitate the truing of the axle in the machine, as hereinafter described. The longitudinal slide C has mounted on it a tool head or carrier, H, fitted so as to be capable of being turned about a vertical axis, as required, in order to present different tools, carried by it, to the work, for which purpose said rotating tool-head is in the same general line with thc revolving chuck. The one of the tools or devices carried by the head H consists of a hollow radial socket, I, which, by moving up the slide C, is first brought in connection with the rough axle, reeei ving the bearing end ofthe latter within it and holding the axle by its point firmly to its place and in true position as regards its axial center, so that it will be an easymatter to true the axle at or by its shank by means of the ball-joint c and adjustment of the jaws ofthe chuck E, to firmly clamp the thimble F, and the axle in the thimble, by the screws I). The slide C is then run back, and the tool-head il turned partly round, to bring a rougheningtcol, J, into line with. the axle, and so that, on forcing up the slide C again, said tool is brought into action on the bearing portion of the axle, to remove the surplus stock, to turn down the end d for the screw-thread, and to pare oft' tothe required length such 'reduced portion. To this end the rougheuing-toolJ is composed of six--more or less-cutters, the advance one, c, of which is set to roughen down the collarjcf the axle, the next one, el, to operate on the shoulder g; the next succeeding` ones, c2 c2, set to form an inelincd series, to take surplus metal from the portion la, and to give thereto its requisite taper in the rough 5 the next one, ci, set to reduce the end (Z for the scrcwth-read; and the last cutter, et, adjusted to pare off the extremity of the reduced portion d--all of such reductions taking place by feeding up the slide C. This having been done, the slide C is again run back and the tool-head ll turned to bring a die, K, in line with the axle, to cut the screw thread on the portion d by runnin g up the slide C, and subsequently the tool-head H turned and slide C adjusted to bring a finishing-tool,
L, into action on the axle by feeding up the This tool L is composed of a continslidc C.
nous straight-edged cutter, fi, set at an angle, to correspond with the required taper of the portion h of the axle, and a cutter, k, shaped to act upon the collar f and shoulder g of the axle. In the back end of this tool or toolholder L is xed a drill, l, for the purpose of drilling the one end of the revolving axle simultaneously with the cutters i and k performing their work. In rear of the head-stock B is also arranged a drill, m, forced up by a handlever, n, for drilling` the center in the shank end of the axle. These centers facilitate the after dressing and finishing of the axle when hardened. A polishin g-tool may also be added to the rotating head II. if desired, for action on the axle after the finishing-tool L. rBhe slide-.rest D carries a cutter-holder, 0, hinged at its outer end to the slide and having a cutter, p, which, as the slide is advanced, serves to trim the edge and back of the collar f. The cutter-holder o is hinged, as described, to admit of its being thrown up or back, as represented in Fig. 3, so as not to interfere with the advance feed of the rougheningtool J and 'finA isliing-tool L.
The axle or half-axle thus iinished is ready, as it is taken from the machine, for dressing or further finishing when hardened, and to be cut and welded at its shank end to its fellow.
The slide G may be worked backward and forward by means of rack and pinion, as shown in the drawing, or by any other suitable means.
The rotating tool-head H, too, may be arrested and locked, when adjusted, by a spring or other stop, to hold the tool presented to the axle in position.
Ve claim as our invention and ldesire to secure by Letters Patentl. The combination of the thimble F, having a spherical portion, c, with the jaw-chuck E and the centering-socket I, substantially as and for the purpose herein set forth.
2. The roughening-tool J, with its cutters e eI e2 c3 e, in combination with the rotating tool head H and slide C, essentially as shown and described.
3. The rotating tool-head H, provided with a centering-socket, I, a roughening-tool, J, a die, K, and a finishing-tool, L, all constructed and arranged essentially as described, in combination with the slide C, for the purposes specified.
4. The drill Zin the rear portion of the iinishing-tool L, in combination with the drill m, arranged in rear of the headstock B and made capable of operation by hand in the axial di reetion of the head-stock, substantially as and for the purpose herein set forth.
