To a 107mm sit may concern:

Be it linowirthalv l, ADoLPu L. Dr. LEEU W, a citizen of tho linitod States, residing at Hamilton, in tho county of Butler and Slate of Ohio, have inventor] certain new and usoful improvements in lool-liceding Meohanism, of which the following is a speoiiioaiion.

My invention rel-airs to tooll'eecling manhanism, such as cnurloyod 'l'or lecding the tool or iools in. incial planing machinery, and has for its object tho providing of feeding means :uctuated by a mo'liro agent ha ring constantrotation in a given direction from a. source indopendonl, of the reciprocating table and reciprocating actuating parts for the table, and constructed for performing the tool-iced at approximarely ilio cnd oi cilhcr the culring. or backing movement of the table, .irrcspia-live of lhe direction of the loud of the lords, i. c. i'coding the tools at either end in oilhcr'diroelion, and arranged so that the tool-iced may he accomplishei'l or not as do sired when manually tripping the tabledrive ,l'or reciprocating the table for short or pariia strokes, for inslanco when testing tho posilioll oi the iool, and the im'ontion will ho readily understood from the following desoriplion and claims, and from the drawings, in which laller:

Fig. is a horizontal so: lion lalicn on the line 2 2 of Fig. '1. Fig: 4 is a side clovaiion of tho poral.ing hcad of my improved devico; and, l ig. 5 is a rros sooiion oi the same on tho lino g 2 oi Fig. -.l. Fig. 5 is a side clcration of one oi thc ralchct and pau'LhoXr-s. Fir. 7 is an axial soclion of lhe same. on ihe lino .r r of Fig. (3. Fig. 8 a dolail, show ing' ihe locdu'acli connection lo i'he ratchet and pau'ldroxcs, shown on tho sci-lion line //,'--1/; ol' Fig. l. Fig. 5) is a sidc cievation, partly in section on tho line 1 of Fig. 10, showing the ral(hot-housing 'ior the sidehoad-feed-scr wv1 and, Fig. H) is a bollom v ew oi thc some.

I have exemplified. my improved dovicc as applied to a racial )laning nun-blue provided with a pair of loo -hcads on ihe cross rail, lire tools being mountod on slidcs, the heads and slidos being moved-b the usual screws and spline .1 rod, actuated b" the usual feed- I'ack, the machine being urt-her provided with side-hoods aclualcd by lho usual feedso'rews. The tool-slide of the ride-heads may also be led by power in any usual manner. 'lhose parts may be of ordinary or usual construction and any one or more of tho same may be employed, or tools oi dillereni character and having dill'crcnl moving agencies may be employed without. departing from the spirit of my invention. Thus 1 represents the frame on which. a table- 2 is caused lo reciprocate forward and back in any ordinary or wcll known manner, as by means of the ordinary table-rack and bull-- VillPil drive, comprising, for instance. the tafblc-rach 3, with which the bull-wheel l on a shaft 5 meshes, a pinion (.5 on a shall. 7 engaging ihe bull-whecl and having thereon a gear 8 engaged by tho gear 9 on a suitable driving shalt ill) having secured ihereto an ordinary str p-pulley 11 having the drii'ing l ar-cs i2 13 wit 1. which hclls 15 iii are adapted to engage for driving lhc drire-shait alternately in op osite dircelions, for respectively causing toe table to movc across the tools for performing the culling oporation on ihe stock carried by tho lahlo or returning the table to initial position ready for a succeeding out upon the stool; by the tools. At tho respective sides of tho step-pulley, loose pulleys 17 l8 rotate loosely about the shall. 10 for receiving the belts in ordinary manner.

There is a belbshi'ltcr 1.) having shifting;- forks 120 21 articulalcd with levers 22 23 hav ingpins .34 25 recoivrd by slols 2G 27 of a. sliding plate 28.

This rross-rail is adapted to have one or more lool-hcads slide laterally thcreon on a guidcway 34. I have shown lhcsc toolhcads at 35 36, adapted to be fed latcrally on the saddle by moans of adj usling screws 37 38. The lools 3U 40 are secured to toolslidos ll 42 adapted lo bo 'lcd on iho heads by moans o'l' screws 43 44, and adapted to be fed by hand or by power in ordinary manner from a splincd shalt 46 is a pinion on tho shall -15 and engages )inions -17 on the adjusting screws 3? 3S. lhcsc pinions -16 -.l7 48 are caused to have operative engagement wilil'i thrlr rcspoclire shaft or screws for opera-tow jhe hitter ia either direction by means 0 the ordinary the stud '75.

ratchet and pawl-boxes 49 50 51 arranged to move the rod and screws in either direction. or to run idle according to the position in which the P2113715 may be set, in usual manner, for feeding the tool-heeds and slides in either direction. Thus each of the ratchet and fill-b02195 may comprise a collar 52 fast on the rod or screw, on which coila-r e. douhie pew 53 on e pin 54 rocks, a handle 55 being on the pin Mend having a finger 55 edap ed to engage e notch 57 in a spring 58 secured to the collar for setting both teeth of the double pawl in neutral position with Z'BlStiJi-OH to an internal ratchet-Wheel 59 on the pinion which is normally loose on the shaft. When the finger 56 is forced out of its notch, either ofthe teeth of the double pewi is caused to have operative engagement with the rate -et- Wheel for piecing the pinion into engagement with the rod or screw.

If desired there may be a table reversing control and attendant parts at the-other side of the machine, indicated by similar but primed reference numerals, which may be in connection with the tel 173 by means of a shaft 185 having arms 186 186 at its XOSlHCilVt ends. The arm 186 has a slot in? into which the end of the pin 160 is received and slides for causing combined movement of the rocking member and arm 136. there being similar cmmeetions at the other side of the machine between the rocking member 156 and the arm res, for causing transference of movement across the machine from thetable reversing control 17-3 to 20 the bolt shifter 19.

iiy means of my improved device, I obtain a quick and positive feed for the toois which is independent of driving connection with the reciprocating parts oi the machine, and by means of my improved device I further obtain accurate feeds which may be definitely gaged. As illustrating the advantages of my iinproved device, it may he stated that by its I the tripper-arnis le reversing control I einploymentthe tool-feed may be accomplished at either end of the stroke of the planer-table, that is to say, the tool-feed may take lace at the end of the cuttin stroke or r n h at the end or the hacking stroke, and also be in either direction at any of the tools. It now the planer-table is set in motion and is moving on its banking stroke in the directionof the arrow (1, the cutting-stroke tappet 168 Wlll engage the trip 166 at approximately 7 4o t-heendoft-hehackingmovement-of thetabL for shifting the belts for initiating the out-ting stroli e of the tabio i thile this belt-shithing is being aeoompiished the reek-shaft; Mt tis being repl ed, thereby also rocking the arm 15] which operates i 148 on the'rod 145 for striking" one of the "ca pets and initiating movement of the eran casing of the ieeding-head, in the direction of the arrow it, will be noticed. however,

' that these tappets 147 148 are spaced apart; on the rod 145 and that the arm 151 has movement between said tappets before it strikes either of the same for shitting-the rod. The positions at which these tappots are set upon the rod determines the mognent at which. the feeding-heed trips are moved for releasing the pew] of the ftfifidiklgd'lQ-fid tor intitiating the movemenfioithe crank-casing of The tripper-arnis-oi' the feed-head are or. eriitedhygthe ast fraction of movementof the rocking in mmor shifting lover of the tahie-eontroi, and the'moment of movement of thetripper-arms reiatively'to the table-reas verse? is determined "the positioning of the between thetappets 14-7 eases? tappets on the rod 145 This movement of referabiy takes piece at the end of the be -shitting movement, in other words, the belts are substantially shifted for reversing the table-movement before the flipper-arms are tripped for aeconipiishing the feeding movement. By this means the operator may, if desired; reverse the tehie-movement to r short or partiai strokes, as for instance in testing the tool-position, by means of the hand-lever, Without effecting any feed of the. tools, by shifting the hand: lever only partially, or, if desired, the operat-olkniay shift the hand-lever to its limit of nioven'ient for eiiect'ing both short or parbial strokes of the table and feeding movements of the tools. fl

By the proper setting of the ratchet and pawl mechanisms and theproper positioning of the crenlepins of the crank-housings at, either sideof't heir roclriiig axes, the food may .be a 'coniplished at will at either end of the table for feeding the toots the desired distances in either direction, which may be aceom )lished either when tripping the lovers by hand or by power.
