To all whont it may concern:
Be it known that we, PHINEAs H. ADAMS and ORSEMAS T. X. AnAMs, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have in vented new and useful Improvements in Boring-Machines, of which the following is a specification.
This invention is a boring-machine, particularly adapted and designed for boring the hubs of pulleys, although not in any way lim-- ited to this use.
The object of the invention is to form an improved machine of this class having a boring-bar supported and guided on both sides of the work.
A further object is to provide means for quickly and accurately centering, chucking, and holding the work while being bored and for then releasing it.
A machine embodying the invention isillustrated in the accompanying drawings.
Referring to the drawings, Figure 1 is a central longitudinal vertical section of the machine. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 thereof. Fig. 4 is a face view of one of the chucks. Fig. 5 is a detail in plan of the feedscrew with a'split nut and associated parts thereon. Fig. 6 is an end view of the parts shown in. Fig. 5.
The machine as shown is of the horizontal kind that is, of the kind in which the cutter bar extends horizontally; but the invention may be applied in a vertical machine.
. The bed-frame is indicated at 6, the headstock at 7, and the tail-stock at 8. In a suitable bearing 9 on the head-stock is a sleeve 10, carrying a driving-gear 11, by which it is retated. Within this sleeve is a spindle 1.2, splined to the sleeve, so as to produce rotation and permit lengthwise movement of the To the front end of the spindle is screwed a boring-bar 13, carrying a cutter 14. This boring bar works through bushingguides 1.5 in the standards 16 on the head and tail stocks and'is centered, supported, and guided thereby. The standards 16 also support the chucks, each of which consists of a spider 17, having near the ends of its arms the beveled centering-lugs 18, which take under the rim of the pulley and act to center and hold the same. To prevent the chucks from turnin they have hooks 19 on the back thereo' which engage with pins 20, projecting inwardly or forwardly from cars 21,
l manner.
formedonthe sides ofthe standards 16, and to hold the bushings in place in the standards they have hooked lugs 15, which engage under bolts'15 on the standards.
As stated, the spindle 12 may be fed forwardly through the sleeve 10 in the operation of the machine. The feed is effected by a screw 22, mounted in suitable bearings in. the head-stock and driven by a gear 23, meshing with a gear 24, carried at the front end of the sleeve 10. indicates a nut which travels 011 said screw, and this nut is attached to the slide 26, which is held between a collar 27 on the spindle and the socket 28 at the rear end of the cutter-bar. The movement of the slide and the feed on the spindle are effected by the operation of the screw in anobvious The nut 25 is split, and the feed is stopped by opening the nut when the cutter has passed through the pulley being bored. To this end the nut-sections have pins 29, which work in cam-slots 30 in a plate 31, carried on the under side 01 the slide 26. This plate is connected by a link 32 to the lever 33, pivoted upon the slide 26, and one arm of this lever works along a rod 34, which is attached to the stationary part of the head-stock and has an adjustablestop-collar 35. When the lever strikes the stop-collar, it shifts the slotted plate so that the pins 29 are brought to the wider portions and the nut is, opened, thereby stopping the feed. The slide and cutter bar and spindle may then be pushed back by hand by means of the handle 36 on the top of the slide.
The means for adjusting the tail-stock to clamp the pulley between the chucks consist of a hand-operated screw 37, which carries a split nut 33, in all essential respects similar to the split nut 25, the split nut being disengaged from the screw by a lever 39. By turning the screw 37 the tail-stock is advanced or retracted to clamp or loosen the pulley or other object being bored. When quick action or adjustment is desired, the feed-nut 38 is disengaged by the lever 39, and the tail-stock is then free to slide back and forth as needed.
Obviously other feed devices than the screw and split nut could be used for moving the boring-bar and the tail-stock, and equivalents may be used for the other parts within the scope of the following claim.
Although the machine shown is oi the horizontal type, the invention is capable of vertical arrangement, and the scope of the invention is not limited to either avertical or ahorizontal machine; also, other chucks than those described maybe used, such as geared chucks, which may be set to accommodate pulleys of different sizes.
5 What We claim as new, and desire to secure by Letters Patent, is
In a boring-machine, in combination head and tail stocks having standards thereon with centered openings, bushings in said openings, 10 a boring-bar which extends through said bushings and is guided and supported there- Witnesses:
