13e it known that l, Wnaas S. Snmmas, residing in Milwaukee. in the eouuty of Milwaukee and State of 'iseonsin, have in vented new and useful lu||n'ove|nent.-: in lInd-Matehers, of whieh the followin v is a demription. referenee being had to t te aeeouumnying drawings, wlneh are a part of this slm'itleation.

This invention relates to end niatehers and has for its ohjeet to provide an end lnateher with means for automatieally truing the work before the eutting operation.

Another ohjeet of the invention is to provide an elul niateher with a roeking or tilting support for the work which will enlise the work to swing into bearing with the guide surface.

'ith the above nml other ohjeets in view the invention eonsista in the end matt-hel eolubinatious of parta alul all et uivalents.

I desire it to e nndepitmd tlhat this invention is not limited to any specific forni or arran Iveulent of parts exec-pt in so far as sueh imitations are speeitied in the elailns.

llefel'rin v to the neeotu ninying drawings in whieh Ii e eharaeters o referenee indieute the salue parts in the ditlerent views: Figure l ia a front elevation of a portion of an end lnatcher eonstrueted in aeeordanee with this invention; Fig. 2 is a side elevation thereof: Fig. is a neetional plan view thereof: and. Fig. 4 is a detail aeetional view of the s )ring emnieetion and mljustlnent means for t te tilting work supporh In theae drawings 10 indieutes the frame of an end lnateher, whieh in this instance cutter heads Il. the head bloek l2 and the prawn' bnr 13, as usual. the traveling head way 15 of tie head bloek by means of n pitnian eonneetion 16` with a driving Ines-hanisln not shown. The presser bar is held in plaee with spring piensan! at ,the desired distance from the headbloek to )erinit the ltmn'ing strip 17 or other lnateria on y'whiehthe work is to ln'iwrfornied to he freely enter`ed therelwtween without unntuvessary lateral play. 'llus is tweoniphshed h v mounting the ends of the n'esser har 13 on studs 1H projeeting from t le head bloek 12 and heldaguinst set nuts l!)l thereon by means of compression springs 20. The work is entered in the guideway between the hend bloek alul the presser bar when the traveling hend 14 is in its lowernlost position. being vuided in plaee on one side b v the bevelet flange l on the presser bar and on the other side by a side plate '.22 of the travelingkbead. 0n bein' entered the worte ia passed beneath n vulde .23 whieh is enrrled v the traveling head nml preferably eonstitutes a later'allv projeeting pin ou a swinging arlu 24 whiei is pivotally mounted to the side plate 22 and is elaniped in various adjustments by means of a nut .25 ou a stud 2li of the side plate, said stud trnwling in an are shaped sot 2T of the arm. The work entering tht` maehine is also guided by bearing on a work support earried by the traveling head and eonstituting the distinguishing feature of this invention.

At the Lower ed re of the side plato Q2 is a laterally extent ing flange 9.8 having a groove in its up wr surfaee forming n seat for the vlower et ge of a tilting or roeking work support 29. tbe seat being not diret-tlv below the part of the work support on 'whiel the work rests. lult to one side, so that the line eonneeting the bearin point of the support on its .seat and the rearing ioint of the work on the sup ort will be ine ined in a diret-tion toward t ie guide surface 30 of the head bloek. 'lhe support 29. while being free to roek in its seat. is normally held in its upright position by having studs Ill projeeting fl'onl it and passing through openings in the flange 2H with eoil springs 32 surroululing theln and bearing at one end against set nuts 33 on the studs and at the other end against bushings 34 whieh are threaded in the openings of the flange .8 and allow of sutlieient play for vthe studs. 'l'he lnishings- 2H are to be adjusted by turning them on their serew threads so as to have the work su )port 2t) rest on their flat upper ends and t ley are held by loek nuts 35. The eife'et of the springs 3*. is to push downwardly on the studs 3l and hold the support 29 with pressure u ion the ends of the bushings so that it wil relnaiu in its returned to itis upright position by in elne of the springe :l2 mi noon es itv is permitted to do so.

The work support ".tt has a slender projeetion :lit in the phuie of the inner edge of the supporting fare and extending into the opening between the head block. Ind the prtwier bar an elearly shown in Figs. 2 and *.l to support the work clone to the cattery. 'lhe projeetion .t is iinide slender to pernnt of the adjustment of the presser bar 13 for the thinnest work for whieh the machine is intended.

ln o eration the atri of tlooring 17 is enterei lietween the ide .23 and the top ol' the support 21| wit i its faee toward the aide phite 2:2. being guided in it:- entry bv the beveleil tlange 2l and is pushed in initil its end strikes a iinst a stop 37 whieh iii lixeil on the hea block t2. 'llie upward iuotion of the traveling head ttl causes the work to niove upwardly therewith with freedoni in the space lietiveeii the head liloek and the ireeeier har until nearing the cnttei' heads wien a slight projection 38 on the nemer bar causes it to be elainped tirinly ietween these parti-i during the action of the entter heats thereon, the face of the wiirk bein pressed agaimit the nide face :ttl of the iiead bleek. Without die rocking or tilting support 20 the upper edge of the work might he pressed into engagement willi the guide face 30 by the projet-,tion-I tlS leaving'the lower edge spared froin said guide faee :tu and thereby result in the enttng of a llaiige at an angle to the faee of the work instead of airallel therewith. llowever. hy nieiins of the tilting or roekiiig work su port the i-.iigageinent of the upper edge o the work with the projection 3H ennuie! the work and the support to beconie a tog 'le in etfeet, their engaging edges swinging in a direction to bring the lower edge of the face of the work tirnily against the guide fiiee 30. 'llie extent of the rocki ing movement of the nu )port 2t) will depend n ion the iosition 'of tie work thereon for i the wor is in engagement with the guide fare l() at its ,lower edge at the start there is no roeking niovenient of the support while if the lower edge of the work is as far away froin the guide faire 30 as it ean 'et at the start, that is in engagement with t ie presser har, the roeking nioveiiient of the support is greatest. it beingalways sullieient to bring the work into -a close engagement with the guide fuee 30 so that the tongue or groove eut in the end thereof, according,r to the nttniber and the piniitiou of the eutter heads, will be true with relation to ita faee. U )on the work passing the eutter heads it is withdriiwii froui the niaeliine and the traveling head returns empty to its lower powition where another strip is fed thereto, the tilting support lniviiig been restored to its npright poaition mi noon n the work watt withdrawn therefrom. t

It' through the wear ot the piirts the atiular position of the work support with reatioli toftlie line of travelo the Atraveln head is lost eorreetio'u nuiy be niade by iii jueiting Ilie bushings lll to raise or lower one end or the `other ol' the work snp mrt.

'lhe guide :Btl 'm adjusted to lit upon the upper edge of the work and when elainped in phii'e serves to prevent the tilting of the work on the work support 2li. even if it is neeessary to lift the entire strip bodily in doing .-:o. 'l'lie iuore iniportant funetion of this guide. however. is to serve as u atop to prevent the work being enught bv the teeth ol' the eutteri: and drawn upwari ly thereby at a faster speed than the niovenieut of the traveling head. wliieli would result in the euttei's aeting as feed roll-i drawing the work up tlierelwtwmn. 'lhis would prolaibly eause a bui-kling of the entterx with the .-|u'inging ol their arbore, or the throwing of the work in a dangerous nuinner. but the present-e of the guide 23 prevents this and iieeessitates the work renininiiig in its position on the traveling head until withdrawn after passing above the projeetion 3S. 'lhe olijeet in direi-ting the teeth of the cutters so as. to iuove with the feed of the work is to prevent the spliutering of the lower edges of the llooving strip.
