CECIL DANIEL ANDREW, OF LONDON, ENGLAND, ASSIGNOR TO NILES-BEMENT-POND COMPANY, OF JERSEY CITY, NEW JERSEY.
INDICATING DEVICE FOR MACHINE-TOOLS.
To all whom it may concern:
Be it known that-I, CECIL DANIEL AN DREW, a citizen of Great Britain, and a resident of London, England, post-otlice address 23 Victoria street, London, S. 7., England, have invented certain new and useful Improvements in Indicating Devices for Machine- Tools, of which the following is a specification.
This invention relates to a device by which the point of the cutting tool is employed as an instrument in indicating the dimensions of the work on which the tool is to operate. As an example, in turning locomotive driving wheels while upon the axle, it is important that two Wheels should be brought to the same diameter, and it is obvious that this common diameter can be no greater than that to which the smallest wheel of the pair will finish. In applying my system to a locomotive driving wheel lathe I provide for quickly determining the greatest diameter which can be common to the pair of wheels and for securing a common diameter.
My invention will be readily understood from the following description taken in connection with the accompanying drawing in which Figure l is a plan of portions of a driving wheel lathe provided with indicating devices exemplifying my present invention: Fig. :2 a side elevation, part vertical section of the toolrest of the lathe: Fig. 3 a plan of the toolholder and tool: and Fig. 4 a plan of a portion of the tool-holder, showing the tool-setting gage. The figures of the drawing are on diverse scales.
In the drawing:1, indicates a bed of a driving wheel lathe: 2, the lathe-centers: the axle supported on the centers: 4, one of the driving wheels fast on the axle: 5, the other driving wheel fast on the axle: 6, the two saddles, titted to slide on the lathe bed: 7, the tool-rests, one arranged for inward and outward movement on each saddle: S, the longitudinal tool-rest slides, one mounted to slide on each tool-rest: t), the tool-holders, one arranged to slide in and out on each toolrest slide: 10. the tool clamps on the tool-holders: 11, the tools clamped to the tool-holders: 12, a swinging gage carried by the front of each tool-holder and having an arm presenting itself in front of the tool pointgthese gages being adapted to swing out of the way after the tool has been prop- Specification of Letters Patent. Application filed September 8, 1909.
Patented J une 14, 1910. Serial No. 516,735.
erly set in the tool-holder: 13, a series of graduations on each saddle: 14, an index carried by the tool-rest base to cooperate with these graduations: 15, a series of graduations carried by each of the longitudinal tool-rest slides 8: 16, an index carried by each tool-holder to cooperate with the last mentioned graduations: 17, a dotted line indicating the periphery of a driving wheel of large diameter: 18, the radius of that diameter: 19, a dotted line indicating the periphery of a wheel of small diameter: and 20, the radius of the last mentioned diameter.
Giving consideration, first, to a single one of the tool carrying devices, the swinging gage 12 is to be set in the position indicated in Fig. 2 .and the point of the tool is to be adjusted to the gage, after which the tool is to be clamped to the tool-holder and the gage swung aside. This adjustment of the tool gives it a definite predetermined overhang beyond the toolholder 9 and, the distance between index 16 and the setting face of gage 12 being a constant known quantity, it follows that the relationship of the toolpoint to the body of the tool-rest may be read from graduations 15. The distance between index 11 and longitudinal slide 8 is a constant known quantity and its follows that the inward and outward position of slide 8, relative to the lathe centers may be read from graduations 13.
The adjustment of the general tool-rest in and out upon the saddle is generally a manner of merely occasional adjustment made to suit in a general way the diameter of the work to be dealt with. the finer adjustments for the tool being effected by mov ing the tool-holder in and out. In other words, in lathes of this character the toolrest base 7 will generally be lirmly secured to the saddle in some position generally suited for the size of the work in hand, and the working adjustment of ,the tool will be made at the tool-holder 9. Graduations 13 may therefore be very coarse. Graduations into inches, or even coarser, may answer for the graduations 13. It is therefore seen that, the tool having been properly set by the gage 12, one may read the gradnations 13 and 15 and ascertain precisely the dis tance of the point of the tool from the lathe eenter.' Therefore, having determined upon a given diameter to be produced by the tool,
loo
and having ascertained the position of the tool-base, the given diameter may be gotten from graduations 15. It is of course to be understood that for Work of a character not calling for large variations in the position of the tool the graduations 13 would not be needed, in other words, it would not always be essential that the tool-rest base 7 was adjustable on the saddle. As thus far considered the device is capable of accurately indicating the diameter of the work produccd by the tool-point.
Now, giving consideration'to the fact that there are two tool-rests, let it be assumed that the pair of wheels 4 and 5 are to be turned to some common diameter, the greatest diameter that can be gotten from the smallest wheel. In such case trial cuts may be made upon both wheels until there has been ascertained the greatest diameter the smaller wheel will turn to, this diameter be ing ascertained from the reading of the scale or scales pertaining to that one of the wheels. This diameter having been determined then both tools are to be set to that diameter and the work proceeded with.
In the illustration, the graduations 15 are shown as being upon the longitudinal slide 8 while their cooperating index 16 is on toolholder 9. It is obvious that these parts may be transposed, the graduations being on the tool-holder and the index on the slide, and the same considerations apply to graduations 18 and their index 14.
