SPECIFICATION forming part of Letters Patent N o. 747,979, dated'December 29, Applicants ined May 9,1903. semina. 156,327. ma man.; A

LVO all. whom it may concerne' K Be it known that I, DONALD A. KENNEDY, a citizen of the United States, and a resident ofAshland, in the county ofAshland and State of Wisconsin, have invented certain new and useful Improvements in Sawmill Machinery; land I do hereby declare that the following is a .planks from transfer conveyers, turn, each plank on edge, center the same, and automatically feed it .to a-resan'machiue.

Hence said invention consists in certa-in peculiarities of consti-notionl and combination of partsbereinafter particularly setvfortli with reference to the accom panying drawings .4 and subsequently claimed.

Figure lof thedrawings represents a partly-- sectional front elevation of a machine in ac-4 cordance with my invention; Fig. 2, a plan View of the same; and Fig. 3, a-llorizontal section view onlhe plane indicated byline 3 3 in the first fignre, looking up.

Eeferringby letter io tthe drawings, A indicatesa. horizontal d rive-shaft provided with a bevel lsoar-pinion B,'in mesh with a bevel gear-wheel C, spiined on a'vertical shaft D, the hub of the gear-wheel being provided `with an outer annular groove engaged by studs b ofthe spanner end of a foot-lever E,

in link connection with a base-plate F, thatl is provided with a bearing for the horizontal .shaft and a step for the vertical shaft.

y Loose on the vertical shaft D in opposition to the upper side ofA the bevel Ioreal-wheel C is a friction-disk G, provided with steps containingl double convex wear-bnttonsc for .the lower ends of vertical spindles H, pertaining to rollers I, that are conically pointed at their `upper extremities to obtain clearance for Bearingstransfer conveyors in a sawmill. for the spindles H constitute parts of a frame J, that is centrally supported onthe shaft D,

anda bracket K, fast to a post L, is made to site directions. y A pulley R is mounted in a,` standard Sor.,

yon lthe other spindle, whereby saidlspindles and the-rollers l therewith are rnninfoappoother suitable support,.`and a iiexibledevice (l run on the pulley connects a connterw'eifglit T with an eye e of the frame J aforafraid.,1

Between the spindles H the vupper end or headof frame .l is preferably semicirc'ulam,

and this frame isl coupled by a` with" anothernsimilarly-headed frame Vz''tha t is loose on a vertical pivot with which a L W is provided, and rollers X simir ones I are in loose spindle con'necti l the latter frame.A The bracket' We'xte'hds' from the post L in a direction opposite to that of bracket'K aforesaid, land to .provide for hand swing of the link-connected frames the one, J, is provided with a handle Y clon-r venient to the operator ofthe'foot-lever aforesaid. v The machine is set np so that p lanksifrom transfer conveyors Z in a sawmil'lorelsewhere will fall onto the 'heads of frainesJ V between the rollers I'I and X X, that arey in" 'planes parallel to the pivots of saidl'frames and normally positioned, asshownbydotted lines in Fig. 2. "A blank being dropped onto said frames and caught between thep'aired rollers land X in the position shownliyfnll lines in Fig. -l, depression'of foot-leverEwill bring the bevel gear-wheel C'intolfriction clntchv with the disk G to canse a rock' of theaforesaid frames in the same direction against resistance of the counterweight T, the

result being a setting up and centering of the plank on edge, as well as an automatic feed of said plank to a conveniently-located resaw-machine.

with automatically return to normal position, and thus the machine is reset for the reception of another plank. Should it happen that a plank is too narrow to fallin tilted position between the paired rollers I and X when these rollers are all in normal position, the frames J V are shifted by means o'f the handle Y to bring said rollers in positionto properly catch said plank sion of the foot-lever. y

While I have shown and described a practical machine for accomplishing' the desired A On release of the foot-lever the frames J V-and parte in connection thereprior to a depresresult, the detail of the machine may be somewhat Avaried fromI what is herein `set forth with'd'ut departing from the scope of my invention. omitted and the gear-wheel C brought into `contact with the lower ends of the spindles H by depression of thefootlever E when it is desirable to mechanically rock the link-counected frames.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is Y L v I 1. A resaw-fee'der comprising coupled pi'v- 'otal frames, a pair of `upwardly-extendinig; I5 rollers carried by each frame on planes parallel to thepivot of same, meansA for driving the rollers constituting one pair 'in opposite directions, mechanism by which-the coupled frames maybe rocked at will in the same dizo rection, and means in connection with one of said frames for automatically restoring both to normal position-whien the rocking mechanism is released. y A resaw-feedercomprising` coupled piv- ,otal frames,a handle arranged and connected te facilitate adjustment of the frames on their pivots in the same direction, means in con- ,nection .with'one of the framesA constituting 'a resistance to pivotal movementof both from 3o normal position, a pair of upwardly-extending rollers carried byxeach frame on planes parallel to the pivot of same means for driving the rollers constituting one pair in oppo- 'site directions, and mechanism `by which to- Vmechanically roc'k'said coupled frames on theirpivots in the saine direction from normal or adjusted position. l

3. A resaw-feedercomprising a vertical'rotatoryshaft, a frame for which the upperend @ofthe shaft serves as a pivot, upwardly-ex tending rollers having spindles inA hearings constituting` parts of the frame, gearing connecting said shaft and spindles to drive the rollers in opposite directions, a friction-diskv A 445 loose on the aforesaid shaft and provided with steps for said spindles, means for clutching the disk to drive the same with the shaft, another pivotal ,frame coupled to the one afore- For instance, the disk G may be brackets, a-stepped shaftfor which one of said, upwardly-extending vrollers carried'hy' the auxiliary frame, and means mmstitutingjoV a resistance to rock of said frames from normal position,

4. A resaw--feeder comprisingr a vertical shaft, a frame for which the shaft serves as a pivot, a lever-controlled gear-wheel splinedon said shaft and in mesh with a drivingpinion, upwardly-extending rollers having spindles in bearings constituting parts of said frame, gearing connecting the aforesaid shaft andthe spindles to drive the latterand roll-v Ie'rs therewith in opposite directions, aloose Africtiondisk opposing a side of said gearwheel and 'provided with steps for said spindles, another pivotal frame coupledmt'o the one aforesaid and having upwardly-extending rollers therewith,.and a counterweight arv. ranued and connected to resist pivotal movel mentpf the coupled frames.

5. A resaw-feeder comprising a post pro- 7 vided with a pair of oppositely-extendingl the brackets constitutes a bearing, a frame' loose on the shaft, upwardly-extending rollers having spindles in` bearings constituting partsof the frame, gearing connecting -said 7 5' 'shaft and the spindles to drive L h'e latter and rollers therewith in opposite directions, alever-con trolled gear-wheelsplinedonthe afore said shaft and in mesh with a drivingfpinion', means by which said frame is put into fric-f tion-clutch with said wheel when the lever is actuated, another frame in pivotal connection with the other of said Brackets and coupled to the frame aforesaid, upwardly-extending rollers carried bythe auxiliary fraine,'aud a counterwightarranged and connected to resist pivotal movement of the coupled-frames, i

In testimony that I claim the -foregoing'l have hereunto set my hand, at Ashland, in the county of Ashland and State of Wlscon- 9o sin, in the'presence of two witnesses.
