AUGUSTUS J. NOYES, OF ONEONIA, ASSIGNOR OF ONE-HALF TO ROBERT C. BLAOKALL, OF ALBANY, NEW YORK. v
MACHINE FOR MILLING CONNECTING-R SD BOXES.
SPECIFICATION forming part of Letters Patent No. 392,164, dated October 30, 1888.
(No model.)
To all whom it'mcty concern;
Be it known that I, AUGUSTUS J. NOYES, of Oneonta, in the county of Otsego, in the State of New York, have inventedanew and useful Portable Milling Machine for Dressing Off Connecting-Rod Brasses and other Similar Purposes,of which the following is a specification.
My invention relates to a simple, light, and effective machine that can be readily moved by hand from place to place Where it is needed for the purposeof removing an excess of metal from the joining faces of the brasses for connecting-rods, journal-boxes, and other similar parts of machines, but especially where such repairs are to be made at places which are remotely or inconveniently located in respect to a shop containing suitable machines for that purpose; and the object of my invention is to provide a simple and effective portable tool or machine for the above-named purpose, and thereby supply a long-felt want in connection with railway machinery. This object I attain by the mechanism illustrated in the accompanying drawings,which are herein referred toand form part of this specification, and in which- Figure 1 is a side elevation of my portable milling-machine. Fig. 2 is a front elevation of the same. Fig. 3 is a longitudinal section at the line X X on Fig. 2, and Fig. 4is a plan view.
As represented in the drawings, Ais the bedpiece of the machine, made substantially in the form shown and having parallel sides 1. Near the rearmost end of said sides vertical guides 2 are erected, and at or near the top of said sides horizontal guideways 3 are formed.
B is a sliding bed,which is fitted to move endwise in the guideways 3 of the bed-piece A, and is provided with apendent lug,4., in which the end of a feed-screw, 5,engages to effect the endwise movements of said sliding bed. The feed-screw 5 is fitted into screw-threads made in the end piece of the bed-piece A, and the arranged transversely to the center line of the bed-piece A. One end of the driving-shaft 7 is provided with a crank-wheel,9, or other appliance for giving a rotatory motion to said shaft, and the opposite end of the latter'is provided with a gear-wheel, 10, which engages with a pinion, 11, on the corresponding end of the cutter-shaft 8,for the purpose of imparting to said cutter-shaft a higher rate of speed than is given to the driving-shaft. A bevel gearwheel, 12, is fitted to slide on a spline, 13, that is inserted longitudinal] yin said driving-shaft, and a forked lever, 14, engages in a circumferential groove in the hub of said bevel gearwheel for the purpose of sliding the latter on the driving-shaft when occasion requires. The gear-wheel12 engages with a corresponding wheel, 15, that is secured upon the lower end of a vertical feed-screw, 16, and whose hub is fitted to rotate in the upper cross-bar of the sliding head 0. The feedscrew 16 fits into a screw-nut, 17, formed in the cross-bar at the top of the vertical guides 2, so that when said feed-screw is rotated it will acquirea vertical feeding movement in a direction that will correspond to the direction in which said screw is rotated. A hand-wheel, 18, is attached to the upper part of said feed-screw for the purpose of rotating the latter when the Wheels 12 and 15 are thrown out of gear to move the sliding head 0 upward or downward, as occasion may require.
D is the cylindrical cutter, which is secured to the cutter-shaft 8, and is provided with a series of obliquely-arranged cutter-teeth, like those commonly made on milling machine cutters.
E is an angle-plate, that is adjustably attached to the sliding bed B,for the purpose of aiding in setting the work in position on said sliding plate. Said angle-plate is preferably provided with a stud-bolt, 19, which, by passing through a clamp-strap, 20,whose outer end is supported by a chock-piece, 21, secures a brass, F,or other piece of work tobe operated on, firmly in place on the sliding bed B.
The operation of my portable milling-machine is as follows: WVhile the sliding head 0 is standing in a raised position where the axis of the cutter-shaft 8 will be above the plane of the upper surface of the piece to be operated on, the brassF or other piece of work is secured to the sliding bed 13, so that the inner end of said brass will slightly overhang the inner end of,the sliding bed, as shown in Fig. 3. The sliding bed Bis then moved by the feedsercw 5 toward the cutter D to bring the work into positiomwhere the required amount of metal will be removed by the operation of said outter. Then, with the wheels 12 and 15 engaged in gear, the driving-shaft 7 is set in motion to rotate the cutter l) and feed-screw 16. lhe latter causes the sliding head 0 to move downwardly at a very moderate rate of speed, and
thereby the cutter D is carried into position while rotating, where its cutting-edges will effect the removal of the excess of metal that it is desirable to dispense with. \Vhile the wheels 12 and 15 are meshed in gear the cutter D will be fed downward, as required, for removing an excess of metal from the joining faces of brasses for connecting-rods; but when the machine is required to be used for removing the metal from the opposite sides of the bore of said brasses contiguous to said joining faces, so that the crown of the brasses will have a fair bearing upon the wrist-pin on whieh it works, the wheels 12 and 15 must be thrown out of gear to permit the sliding head 0 to he moved into position to bring the upper side-or the lower side, if required-of the cutter D opposite the point where the metal is to be cut away. The cutter-,which to do this work must be of smaller diameter than the bore of the brass, is set in motion by the driving-shaft 7, and the sliding bed Bis fed toward the cutter D by means of the feed-screw 5 until the required amount of the excess is cut away from the side that is first operated on. Then the sliding bed is drawn back by the feed-screw 5 and the sliding head B moved into position opposite to the point of the here where the metal is to he removed from the opposite side of the bore. Then the sliding bed is fed forward and the entterD again rotated, as ahovedeseribed, until the work is completed.
I claim as my invention A portable milling-machine consisting ofthe following parts: a bedpiece provided with horizontal and vertical guidways, a sliding bed fitted to move by means of a feed-screw in said horizontal guideways, and a sliding head fitted to move by means of a feed-screw in said vertieal guideways, said sliding head carrying a driving-shaft that is diseonnectibly geared to the ieedserew for said sliding head, and a cutter-shaft which is geared to said driving-shaft, and to which a milling-cutter is secured, said drivingshaft and cutter-shaft being fitted to rotate in and to be carried upwardly and downwardly by said sliding head, as and for the purpose specified.
