CLAES e. SHEDIN, OF soMERvILLE, MASSACHUSETTS.
MILLING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 615,313, dated December 6, 1898.
Application filed August 9 1898- To all whom it may concern.-
Be it known that I, CLAES G. SHEDIN, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Milling-Machines, of which the following is a specification.
This invention relates to improvements in milling-machines; and it has for its object the milling of semicylindrical or oval Surfaces, such as journal-bearings, &c., and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a side elevation of a milling-machine provided with my improved attachment. Fig. 2 represents afront elevation of the same. Fig. 3 represents a detail side elevation of the pivoted links and attachment to the sliding work-support table. Fig. 4 represents a detail top plan view of said pivoted links, and Fig. 5 represents a cross section on the'line 5 5 shown in Fig. 2.
Similar letters refer to similar parts wherever they occur on the different parts of the drawings.
In the drawings, A represents the frame or standard of a well-known form of a millingmachine, 011 which B is the bracket, vertically adjustable in guides thereon.
C is the sliding work-supporting table movable in guides on the bracket 13, as usual.
D represents the vise or clamp 011 the table 0 for holding the work S that is to be milled.
A A represent vertical uprights on the Standard A, as usual.
A represents the horn or outer support for the milling-tool spindle.
E represents the rotary milling-tool-driving shaft, which is set in rotary motion by beltpower applied to its cone-pulleyE', as is common in machines of this kind.
6 represents the milling tool or cutter secured to the shaft E.
E is a pulley secured to vthe rear end of the Shaft E, from which leads a belt G to a pulley F on the shaft F, to which is secured a cone-pulley F, from which leads a belt I to a cone-pulley H, secured to a shaft H, suitably journaled in bearings, and to the inner end of said shaft is secured a bevel-gear h, the teeth of which mesh in a bevel-gear k, secured to a shaft K, journaled in suitable bear- Serial No. 688,173. (No model.)
ings attached to the standard A, as shown. To the lower end of the shaft K is secured a bevel-gear is, adapted to interinesh intermittently with bevel-gears Z and Z, splined and longitudinally adjustable on the shaft L, as shown in Fig. l.
L is a lever for adjusting the gears Z Z on the shaft L, so as to cause either one of said gears to bein gear with the bevel-gear 70, according to the direction in which it is desired to rotate the shaft L.
To the forward end of the shaft L is secured abevel-gear Z", the teeth of which mesh in a similar bevel-gear b, which latter has its hub provided with a female screw-thread surrounding the vertical screw-threaded spindle B, the upper end of which is secured to the vertically-adjustable bracket B, as shown in Figs. 1 and 2.
- On one side of the frame of the machine are arranged guides A, in which the inner ends 0 P of the respective links 0 P are guided for a purpose, as will hereinafter be more fully described.
To one side of the frame of the machine is secured or made integral therewith a plate A provided with vertical guides of 0. in which is vertically adjustable the plate M, which is preferably adjustable by means of a screw on. (Shown in Fig. 2.)
On the plate M is pivoted at 7L a guide-bar N, adapted to be Secured at its upper end to the plate M, preferably by means of a fastening-screw n or other similar device.
m m are Screw-threaded perforations in the plate M for the purpose of securing the guide-bar N in any desired position on the plate M, according to the curvature that is to be made on the articles to be milled.
n is a suitable handle on the guide-bar N for the operator to take hold of when adj usting the position of said guide-bar on the said plate M.
0 and P represent links having their inner ends 0 P adapted to move up and down in the guide A, as Shown. Said links are pivoted together and to a pin or bolt Q, passing through an ear or projection on the work-supporting table 0, as shown in Fig. 2.
The link 0 is provided with an extension 0, to the free end of whichis pivoted at O a cross-head R, provided at its ends with antifllGiilOll-lOllQl'S r r, adapted to roll against opposite sides of the guide-bar N during the vertical and horizontal movement of the worksupport 0.
The guideN during the vertical adjustment of the work-supporting plate 0 serves to impart a horizontal movement to the latter, causing thereby the piece S to be moved in a curved path relative to the rotary millingtool 6, thus causing the latter to cut or mill the article operated on in the desired curvature, circular or otherwise, as may be desired, according to the position of the guide-bar N on the plate M..
By adjusting the plate M up or down on the stationary plate or bracket A articles of various sizes or diameters may be milled, as may be desired.
By adjusting the'position of the bar N on the plate M any desired curvature may be produced on the article acted upon by the rotary milling-tool.
In using this my improved inillingmachine the article S to be milled is secured in the vise D upon the table 0 after the plate M has been adjusted on the bracket A according to the size of the article to be milled. The position of the bar N is then adjusted on the plate M, according to the curvature, semicylindrical or otherwise, that is to be given to the article that is being milled. Rotarv motion is then imparted to the millingtool or cutter e in the usual manner. By moving and securing the lever L in the position shown in Fig. 1 the bevel-gear Z is put in gear with the bevel-gear 70. By the rotation of the pulley H a rotary motion is imparted to the shaft L, causing the screwthreaded gear I) to move the bracket B, its table 0, and workS, secured thereon, downward, as shown by the arrow in Fig. 2, and during such downward movement of the worksupport 0 it is simultaneously caused to move sidewise in the direction of the arrow shown upon it in Fig. 2 by the influence of the guidebar N, rollers r r, and intermediate connecting mechanism between said rollers and the table 0, causing the latter and the article S, secured to it, to move in a circular or curved path until the cutter or milling-tool e reaches the highest part of the article that is being milled, when the operator first swings the lever N to the position shown in dotted lines in Fig. 2 and secures it in such position and reverses the rotary motion of the shaft L by swinging the lever L to the position shown in dotted lines in Fig. 1,-by which the gear Z is put in gear with the bevel-gear 7c and the gear Z disconnected therefrom, causing the rotary motion of the shaft L to be reversed, and consequently causing the bracket B, table 0, and work S to be gradually moved upward and the table 0 and the work S secured thereto to be moved in the same direction as before, causing the other half of the article to be milled and shaped to the desired curvature.
Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claiin- In a milling-machine, in combination, arotary milling tool, a frame or standard, a brack et vertically adjustable thereon, a work support laterally sliding on said bracket, a stationary frame extension A a plate M vertically adjustable on the latter, a lever N pivotallv adj nstable on said plate ill, a pair of levers O, O, P pivoted together and to the work-support, said levers being guided on the guide-bar N during the up-and-down motion of the bracket and the horizontal motion of the work-support, substantially as and for the purpose set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
CLAFS G. SHEDIN.
