Specification of Letters Patent.

Patented Sept. '9', 1919.

Application filed November 15, 1 918. Serial No. 282,706.

Be it known that I, FRANK B..1YINcLINe, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Shaper-Feeds, of which the following is a specification. j j a ,m

This invention pertains to improvements in the feed mechanism for metal shapers,

and the improvements will be readily under stood from the following description taken in connection with the accompanying drawings in which t Figure l is a side elevation of a portion of l the body of a shaping machine provided with an exemplification of my improvement in feed mechanism, a part in this View appearing in vertical section in the plane of line d of Figs. 2 and 4::

Fig. 2 a plan of thesame parts, thecolumn appearing in horizontal section in the plane of line f of Fig. 1 j

Fig. 3 a horizontal section the plane of line a of Figs. 1, 4, 5 and .6: r

Fig. 4 a vertical section in the plane of line b of Figs. 1, 2 and 8:

Fig. 5 a vertical section in the plane of line 6 of Figs. 1, 2 and 3: and

Fig. 6 a vertical section in the plane of line 0 of Figs. 2 and 3.

In the clrawings 1, indicates the column shaping machine: r

2, its vertical front guideway:

3, the rail, arranged as usual to be adjusted vertically on this. guideway:

4, one of the journals of the actuatii'n, mechanism of the shaper, this journal proof an ordinary jecting out through oneof the side-Walls "of the body: and v 5, a bearing for this journal, having a concentric exterior projecting out from the body of the shaper. i

It is the purpose of my improvements to cause the journal 4 to produce the feeding motion for the feed-screw of the rail, in such manner as to provide a satisfactory and convenient ratchet-feed which can be readily adjusted in degree, and direction of feeding motion, while the machine is in motion.

Proceeding with the drawings 6, indicates a short countershaft ournaled in one end of the rail, parallel with the rail,

rearward of the face of the rail 7 a pair of bevel-gears provided with separated clutch-hubs, mounted loosely on this countershaft, in a recess in the rear face of the rail, across which recess the countershaft passes: l

7, a clutch-hub splined on the countershaft "and adapted to look a selected one of the two bevel-gears to the countershaftz 7 a pivoted hand-lever: for throwing the *clutcli-hub, this hand-lever being provided with a spring detent tohold it either in the neutral position or with one of the bevelgears clutched to the countershaft:

. 8, a splined shaft designed to have rotary .motion imparted to it from the journal 4L and, in turn, to transmit intermittent motion to a selected one of the bevel-gears on the countershaft: jj

9, a bevel-gearloose on the forward end of this splined shaft and engaging the two bevel-gears 7 a l 10, acasing swiveled on the bearing 5 and split vertically to permit its attachment to the hearing 5: r 1

11, a bearing projecting forwardly from this casing and forming a hearing for the shaft 8, the axis of which shaft issome distance below theaxis of bearing 4, bearing 11 having a cylindrical exterior concentric with shaft 8:

11*, an eccentric secured to the outer end of journal 4, outwardly beyond shaft 8:

11 an eccentric-rod having strapped engagement with the eccentric:

12, a forked arm formed in tWOuhktlVGS, splined on shaft 8, this arm having concentric hubs journaled in the casing 10:

13,11. crosshead fitted to slidevertically in casing :10 below and outwardly beyond the eccentric: a a

14, a horizontal crosshead-pi-n projecting from the cross head toward the body of the shaper: and 1 15, \ablock, fitted to turn and slide on thi pin, this block being disposed within the bifurcation of forked arm 12 and having trunnions "engaging the bifurcations.

As the journal l revolves it causes the eccentric toreciprocate pin 14, which reciprocation produces an oscillating motion for splined shaft 8. The crosshead guides the lower end of the eccentric-rod vertically,

and the sliding of block 1-5 on the pin compensates for the arcof movement of the trunnions of the bloclr. The split case 10 permits it 'to be readily applied to the bearing 5, and the splitting of forked arm 12 permits trunnion block to be readily put in place.

' Proceeding with the drawings 16, indicates a horizontally split case for the bevel gears on the countershaft, thecase being swiveledrelative to the countershaft: 17, a concentric hub projecting rearwardly from this case and loosely fitting the rear wardly projecting hub of bevel-gear 9:

18, a horizontally split ratchet-case swiveled upon hub 17: l r

19, a rearward prolongation of case 18 swiveled upon bearing 11 and having a sliding engagementwithbearing 11;

20, a toothed segment liXedto hub 17,

' within case 18 21, a handle projecting'outwardly from case 18 to "facilitate the angular adjustment of case 18' relative to case 16 and '22, a spring detent-pin carried by case 18 and engaging a selected tooth in segment 20.

" Casings 10, 16 and 18', together, form a casing swiveled at one end upon the countershaft' and upon the other end to bearing5,

parts 11 and 19 constituting a telescopic arrangement which permits the general. length of the casing to alter itself as the rail is adjusted higher or lower upon the column of the machine. It is in this general casing that splined shaft 8 is journaled; its spline permitting it to slide through forked arm 12 as the length of the general casing becomes altered; Ratchet case 18 may be adjusted angularly with reference to the two other casing members, by means of handle 21, the detent pin 22 serving to fix the ratehetscase in adjusted position. The spring of detent pin 22 is illustrated as being dis posed within the handle 21. The juncture between cases 16 and 18 may be'graduated 'to indicate the'angular position into which case 18 has been adjusted by means of handle 21.

ZPrOceeding with the drawings 23, indicates a ratchet-wheel fast on the 'liub'of bevelgear 9, within the ratchet-cas ing, so that the turning of the ratchet-wheel will effect the turning of bevel-gear 9:

24:, a pawl-carrier keyed to the splined shaft alongside the ratchet-wheel:

25, a spring-pawl carried by the pawl carrier'and engaging the ratchet-teeth:

26, a roller carried by pawl 25: 27, a trackw-ay on the inwall of the ratchet case, adapted to be engaged by roller 26 and cause the pawl to beheld out of engagement with the ratchet-teeth so long as the roller is traversing the trackway:

2.8, a spring stop-pawl carried by segment 20 and adapted to engage a tooth in the ratchet-wheel and prevent pawl 25 from dragging the ratchet-wheel backward on the return stroke of pawl-25z 29, a gear loose on the outer projecting end of counter-shaft 6:

30, friction-disks serving to lock gear 29 yieldingly to the counter-shaft:

31, the feed-screw of the rail, the end of this screw projecting, as usual, from the end of the rail to receive a crank by means of which the screw may be turned:

32, a pinion mounted on the projecting end of the rail screw and engaging gear 29, this pinion being preferably removable from the end of the rail-screw: and

Y38, the usual horizontal shaft j ournaled in the rail, to be bevel-geared to the elevating screw of the rail, this shaft projecting from the end of the rail and being adapted to be turned by hand, or, if desired, to have placed uponit the pinion 32 removed from the rail screw.

Looking at Fig. 5, and understanding that the shaft 8 is gven an oscillating motion by means of the mechanism driven by the eccentric, it is obvious that the pawl-carrier and pawl will bring about an intermittently advancing rotation of the ratchet-wheel and of bevel-gear 9. Normally, the degree of advance of the ratchet-wheel would be measured by the stroke of the pawl-carrier, and the intermittently advancing motion f bevelgear 9 willbe transmitted to the countershaft when the clutch is thrown by means of the handlever 7".

This motion of the countershaft becomes transmitted to the rail screw, and if the limit of feeding motion of the rail screw be exshall indicate the direction of feed, that is to say, when the hand-lever is adjusted to position away from the column of the shaper, the rail-screw will efiect a corresponding feeding motion, while if the hand-lever be adjusted toward the shaper column the rail screw will effect a feeding motion in the opposite direction, or the hand-lever may be locked by its detent in the neutral position.

' Looking again at Fig. 5, and giving consideration to the trackway 27, as the parts are shown the pawl-carrier may efi'ect the advance of the ratchet-wheel throughout its forward stroke, which the drawing shows as having been just completed. The trackway is in such case without ollice. But if 1 case 18 be angularly adjusted so that detent pin 22 is in the final instead of the initial notch in segment 20, then trackway 27 comes into play and is engaged by roller 26 throughout the forward and backward strokes of the pawl carrier, and the pawl ara 4,49

a portion of its stroke only, and the pawl will engage the ratchet Wheel and advance it during only the remainder of the stroke of the pawl. By this means the degree of advance ofthe feed may be regulated with out stopping the shaper, and so, also, may hand-lever 7 b be thrown to either of its extremes or the neutral without stopping the machine.

It is to he understood that the mechanism particularly set forth embodies but a single exemplification of my invention. sought to explain the principle of my invention and the best mode in which I at present contemplate embodying that principle.
