CUTTER-HEAD.
SPECIFICATION forming part of Letters Patent No. 324,041, dated August 11,1885.
Application filed May 4, 1885. (No model.)
T 0 all whom, it may concern.-
Be it known that we, SALMON WV. PUTNAM and WILLIAM A. FOSTER, citizens of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented a new and useful Gutter- Head, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming .part of this specification, in which Figure 1 represents a vertical sectional view of a cutter head embodying. our improvements. Fig. 2 is a cross-sectional view on the line :0 x of Fig. 1. Fig. 3 is a detail of one of the cutters.
Our invention relates to cutter-heads, and, although susceptible of wide application in the mechanical art, is particularly adapted to the boring and sizing of the axle-holes in carwheels. The prominent advantages arising from its use are, greater rapidity and accuracy in the production of such work than has in most cases heretofore been achieved.
Our invention consists in the construction, arrangement, and combination of devices, all of which we will hereinafter fully describe, and specifically point out in the claims.
To enable others skilled in the art to which our invention appertains to understand it, we will now proceed to describe the manner in which we have carried it out.
This invention is especially designed to be used in connection with a boring-machine such as is illustrated and described in Letters Patent No. 240,458, granted to Salmon NV. Putnam, April 19, 1881.
The usual practice at the present time in boring car-wheels has been to use a single double-ended cutteri. 6., a cutter passing through the arbor itself with a cut on each end. In our improvement a cutter-head is affixed to the arbor by means of a key or equivalent device, the said cutter-head carrying a series of cutters so arranged that they may be expanded diametrically from or toward a common center either independently or collectively, all of which will be hereinafter described.
Referring to the said drawings for a more complete explanation of our invention, A represents the lower part of a boring-spindle,
which is provided with reduced cylindrical ends a and b, for the reception, respectively, of a hollow cylindrical sleeve, B, which carries the cutters, andacone-shaped adj usting-sleeve, D. 5 5 The cylindrical reduced end a is slotted transversely at 0, and the hollow sleeve is similarly slotted at (I, while a key, 0, or equivalent device is adapted to engage these slots and firmly secure the cutter-head to the boring-spindle. 6c The extreme lower end of the boring-spindle A has a threaded perforation, 6, adapted to receive a screw, E, provided with collars f and g, which engage the cone-shaped sleeve D, and adjust the cutters toward or from their common center. The outer end of the screw may be squared, to better facilitate its operation. The cylindrical hollow sleeve B is provided with an interior shoulder, h, which abuts against the shoulder a, formed by the reduced end I), and the inner surface of the hollow sleeve at its lower end is tapered and corresponds, approximately, to the size and configuration of the adjusting-sleeve D. This lower portion of the hollow sleeve is slotted at Z, and in these slots are placed the radiating cutters m, preferably six in number, their inner ends bearing against the cone-shaped sleeve, which adjusts them toward or from their common center, while their outer ends are beveled to form suitable cuttingedges. Through the lower end of the cylindrical sleeve Bis aseries of screws, F, which securely hold the cutters in any position desired.
From the foregoing description it is manifest our cutter-head has many advantages. By the use of our cutter-head we have (by choice) six cutters, which enable us to increase the rate of feed to three-fourths to one revolution, and still each cutter will be required to suso tain but one-eighth out. It will thus be seen that in a given time we can do one-third more work than. has hitherto been accomplished, and without forcing our cutters beyond a point ofemlurance. Again, by arranging our 5 cutters so that they may be expanded as one or all of them become worn or dulled,we can take the cutters out separately, or take the cutterhead off entire, expand the cutters, (or cutter,)
resharpen them on a simple grinding arrange- Ioo ment, and replace the cutter-head on the arbor, and it can cutthe original size. The cuttors may be sharpened in this way many times. The advantages arising from this expansion system are, that with one set of cutters it on ables various sizes of holes to be bored, this feature being valuable in repairing car-wheels and ear-axles, as required in railroad and lo comotive shops; also, when car-wheels are hard or unevenly cored, it is desirable to first take a roughing-out out, leaving but a small amount of stock to be removed for the following finishing chip. In this case, for the first cut, the cutters are contracted, (by turning the screw which operates the conical sleeve in the cutter-heath) and after the roughing-out cut is taken they are then expanded for the finishing size.
The cutter-head as shown represents all the cutters as cutting on thesame plane. We, however, deviate from this plan in some cases by having one or more of the cutters located to out somewhat in advance of the other cutters, tor the purpose of having the leading cutter remove the scale from the metal, thereby prolonging the lite ol' the cnttingedges of the sizing or finishing cutters. This may be accomplished by means of the screw 1, which enters the base of the cutter and bears against the adjusting-sleeve.
The advancing cutter (which is the first one dulled) may be taken out by itself and resharpened on an ordinary grindstone.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is t 1. The combination, with the arbor and a cutter-head detachably secured to the arbor, of suitable adj ustably-secured radial eutters,substantially as herein described.
2. In combination with the arbor and cutter-head, a series of cutters which admit of a radial adjustment from a common center, both universally and independently, substantially as herein described.
3. The combination, with the arbor and cutter'head, of cutters attached to said cutterhead and means, substantially as described,
whereby one or more of the cutters may be adjusted to cut in advance of the remaining cutters, substantially as and for the purpose described.
