To all vwlw/m 'it may concern:

Be it known that I, I--lonAon M. Hoeven, a citizen of the United States, residing at Per rysburg, in the county of VW ood and State of Ohio, have invented certain new and useful Improvements in VVoothFiber M achines; and l do declare the following to be a full, clear,

and exact description of vthe invention., such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyof reference marked thereon, which form a part of this speciiication. V

My invention relates to that class of Wood working machines in which a gang of saws, forming a eutter-head, operating upon the surface of a bolt or log of wood reduces the log to a -liber ol' greater or less iineness.

The object of my invention is to provide a simple and ellieient means for presenting'and feeding the log or bolt or a series of logs and bolts to the cutter-head or a series of .cutterheads.

I attain these objects by means of the devices and arrangement of parts hereinafter described and shown, and illustrated in the accompanying drawings, made part hereof, in whiehr- Figure I is a side-elevation of my device, with part ol' thc center pillar broken away to show its interior arrangement; ltig. 2, a sideeleva#l en of the same, seen from the side opposite that shown in liig. l; lfig. il, a sideclevation partly in section of the detachable dog, hereinafter referred to, designed to engage the ends of the bolt o'l log to be supported and operated upon; liig. 4, a topplan view of thc same; Fig. 5, a side-elevation of another dog, hereinafter referred to, designed to engage the sides of the bolt or log to be operated upon; Fig. (l, a to -plan view ofthe same, Fig. 7, a part of Lie gearing, hereinafter referred to, on an enlarged scale, showing a moditicd form of `construction; Fig. 8, a top-plan View ol' a segment of the log or bolt rarrlagc hereinafter referred to, and Fig. l),

a perspective view of the feed-screw and its threaded nut or bracket hereinafter referred to. r

Like numerals and letters of reference indicate like parts throughout the drawings.

ln the drawings, l is a stout base or frame rigidly supporting at its middle a strong pil -lo\\'-hlock 2 from which springs vertically a l hollow-pillar 3 having at opposite sides longitudinal slots 3 mg drawings, and to the letters and figuresv This pillar has a vertically movable collar 3b, also a head 3c. These lugs are designed and arranged to be connected with guy-Wires or ropes to steady the pillar in its vertical position. S is a heavy screw supported crtically within and arranged axially of the pillar 3. This screw 'carries a nut or bracket N from opposite sides of which project arms N', the extremilties of which pass through the slots 3 in the pillar 3. These extremitiessupport the collar 3b, which is rovided with shallow notches on itsl under si e which engage the extremities of the arms N and prevent the collar from revolving.

fl is a circular carriage or platform having around itsl periphery cogs 4, and having central hub 4l which loosely embracesthe pillar 3. Secured to near the top of the pil ar is a stout arm or bracket 5 projecting outwardly and curved downwardly. 1n the outer extremity of this arm is journaled, as at 5, a vertically elongated pinion 6 which engages anddrives the teeth 4a of the carriage 4t. At bottom, the shaft 6, ofthe pinion (l, is provided With a friction-disk 7. This shaft is also provided with a `pinion 8 fixed upon said shaft. Pinion S is engaged with and is adapted to drive a frietionewheel orl disk 9 having a toothed periphery and supported in a cross-arm of the frame, as at 9a. (See Figs. 1 and 2.) 10 is a shaft on which is a frictioi'i-wheel 11 movable longitudinally `of the shaft but revoluble therewith. The outer extremity of the shaft 1() may be raised and lowered by means of lever 12, fulclrumed, as at 13, and controlled by a screw 14 vertically movable in fixed nut 15, supported-in bracket 16, and operated by hand-crank 17. At its inner end shaft l() has sulieient play to permit the outer end of the shaft tobe raised or lowered slightly, thus bringing the friction-wheel 1l in contact either with ,the up er friction-wheel 9 or the lower friction-W reel 7 as the ense may be. i

.ln Fig. 7 l have shown the friction-disk 9 as internally toothed, us at 9, and driven by r an internal spur-cog 9b on shaft 9c which-car: ries another spur-gear 9d engaged with the spur-geur 8. This modification is provided for reducing the motion of disk 9 in certain kinds of work and upon certain kinds of' wood.

18 is the driving pulley upon the outer end of the shaft of the cutter-head 19. This ffl end of the plaie-30Il at the opposite end ol the housing is slotted, as at 30, (see Fig. 4i.) This end is pressed upwardly against the under side of thc carriage et where it is engaged by a button `3U which slips through the slot in the endpiatc and which has a handle 30P by means of which the button is thrown into or out of engagement with the housing 30.

To further secure the log or bolt in place, I provide a pair of dogs which engage the sides of the logr or bolt near its top. These dogs may bc constructed and operatedv as follows: fil-31 are a pair ol brackets bolted or riveted at 32, (sec Fig. 8,) to the top of the carriage 4. ln these lbrackets are openings.

through which pass horizontally the ends of a pairy of parallel rack bars 33 having their teeth uppermost. To the bottonvside of each of these rack-bars is secured a dog 34, the two dogs opposingr cach other at opposite ends of the barv Through the top of the brackets pass set-screws 35 which engage the rack-bars and securely hold them against movement. The rac-lebens are operated by means ot a lever passed between then)- wardly projecting teeth on thebars as indricated by dotted lines in Fig. 6. After the log or bolt is secured-and put in place by means of the end dogs, the side dogs are also moved into engagement with the sides of the log at its middle and the bars 33 are secured in place by means of the set-screws It will be understood Without illustration that cach of the openings of the carriafre or table is provided with the dogs and mec ian ism for controllingr the same here described.

The cutter-head 19 may consist of any usual or preferred construction. In mymachine l prefer to use a )lurality of outterheads, such as here described, disposed in the same horizontal I ilane. In the machine illustrated in the rawingrs there are two of these cutter-heads placed at a right-angle to each. other, one of tliern beine; driven by an independent belt and pulley 37. (See Fig. 2.)

For the purpose oi adiusting the two cutter-heads verticallyl 'l lave mounted and journaled each cutter-head in a stout yoke or housing 38. This yoke or housing; is verti cally movable in ways 39, secured tothe frame oll the machine. 4() is a shaft, jour nalcd in the frame ol' the machine, provided with cams 41 each of which has an arm 42 which is pivotally connected, asl at 48, with the yoke or housing 38. Upon the outer end ol" the shaft 40 is a Worin-Wheel l,44 engaged by a worm 45, the shaft of which is journnled in a bracket 45 and is provided with a hand-` crank 46. iWhen the hand-crank is turned the` worm-gear causes the shaft 4U to revolve and thus the cams on the shai't a0, through arms 42, cause the vole or housing to ascend or descend according to the direction in which 55 the handcrank is turned. It will 'be seen that the Worm-gear 44-45 holds the shaft 4() its cam and the connections with the yoke or housing at all times rigidly locked in position. This adjustment may be used to accommodate the Wear of the cutters and to accommodate the varying depth of the successive cuts of thi` two or more cutterdieads. (,)ther means of vertically adjusting the cut "ters will suggest theniseirrs and l do not,

therefore, limit this feature of my invention to the` constructimi here shown.

The further operation of my device is as follows: Assuming' that the logs or bolts oi wood to he operated upon are secured, by means of the dogs, in position, to the carriage or table fi() as above described; that the table is rwroivingY upon its axis and slowly de sccudinp; upon the screw S, und that the cutter-heads are rapidly revolving upon their shafts. The bottoni ot the logs or bolts Will now in succession come in contact u'iththe tops of each of the cutterdieads, and at each revolution of the table a portion ci the logs or bolts will he removed and reduced to i'iber, the removed portion corresponding with the lead ot' the thread on thc screw Havingr described my invention, what i claim and desire to secure by .Letters Patent, is
