In the drawings above 1nentioned, A represents the inuin frame for supporting the operative `parts of tlieineohanism, such frame beingconstructedA in any proper manner and of anysnitable material. It has a set of slideways, B B', applied to a perforated'plate, C-,M

elevated vertically on the top ofthe traine, as

' When .a plane-iron has itscutting-edgev standin gat right angles to the'pathlor direction iin-which it is moved, it will remove a shaving and` giveto said shaving aspiral bend ylike that'of the mainspring of a watch., Now such a bend as' this is not what is sought to be made -by our machine, and not such as will besufticient to impart to the-shaving the elasticity that may be required to render it useful as bed-stuffing..

AOur machine, as said before, gives to it a helix curved'bend .or curl,as it may be v termed, and while the'front cutter or planeiron removes aseries of curled shavings from the piece ot' woodvthe rear cutter, which is vnot a grooved one, performs the operation 'of cutting away the tongues left between ythe grooves in reduces-.suchtongues to Acurled shavings. t `New, We would remark thatv we Vare well aware-that 'a planestock` has had'applied to it -a series of scoring-knives and .a planeiron, the scoring-knives -being placed inadvance of the-plane-iron, andfmad'eV simply to' cut into` the wood in -parallelflines without removing any part of it, thel whole amount of VVwoodremoved being separated fromthe-block orpiece of wood by means of the plane-iron. -l This is an entirely different operati-on from that can riedon by the cutter of our machine, as the forward cutter or grooved plane-iron of said machine performs 'the function of' not yonly cutting into the wood, but of removing sbavings from it at th-esarne time, and it cuts away planed off bythe rear cutter.k 'By this process of operatingthe wood is not compacted or pressed together, as it would -be by scoringkni.ves, the action` of such'scoring-knives by so compacting it being such as to prevent it to a great exent'fronrbeing'curled by the plane.-iron, 'particularly it' tl1e`.Wood .is lvery dry. e Transversely of the machin-cand- -under the feeding'carriag'e is arranged a yfeediiig-screw, R, on which is' a ratchet, S, such ratchet being iixed'to the'screwxand moved with an intermittent rotarymotion by meansv of an impelling rockenpawl, T, that turns on a screw shaft as a fulcrum, .andhas a reciprocating movement'imparted tov itfby meansof a con- A reratchet.v The `feeding-'carriage supports a weighted lever, X, that turnson a fulcrum,

m, andy is connected 'to a sliding block, Y, by means of a connecting-link, n.v The said sliding block Y is supported by and underneath the ieeding-carriage, and so as to play freely upwardar'id downward.A It is formed to rest:

small projections or chasers, 'r 7:,"which, when .the block rests on the screw, is made to enter between the threads of the screw, andso that when the screw is revolved while these -projections are between its thread a movement of the feeding-carriage toward the plane-stockl will beproduced. By means of the Weighted lever X the block Y may be raised labove or lowered down upon the screw,as circumstances may require. The said lever X carries asmall y, tripping-rest, s, which, when the lever is dev pressed, takes the position as seen in Fig. 3'; but when theleveris elevated it turns by its own weight and takes the position as denoted by dotted lines in Fig. 3, it serving, under these circumstances, to maintain the elevation of the i lever, and this by resting on the top ofthe feeding-carri age and bearing against the lever. This tripping-rest is formedas a lever, as seen in the drawings,and made to turn on a ful crum'or pin, t, extended 'through the lever X, .the said tripping-rest being inserted in a slot, u, formed in the lever. The feeding-screw is provided with a scroll-cam, Z, an inner side view of which is represented in Fig. 9. This scroll-cam is placed near the front end .of the screw, and is s o ixed to the screw as to rotate with it. There is a small projection, v, ex!V tended from the front lside of the block Y, and when this projection passes over the periphery of the scroll-cam such scroll-cam, during its revolution and by its pressure against the pro- .jection, will elevate the block Y, and so as to arrest the lfurther feeding forward of the feeding-carriage. from the block of Wood during aforward mo,- .tion lof the-plane-st'ock onehalf the amount of wood [to be removed, the remainder being- Having thus described our ma would remark that We claim- 1. The groo-ved or grooving plane`-iron, as

' used in combination with'and in front of the common o'r shaving plane-iron, and so arranged that by their operationv one after the other they both shall remove the shaving from the wood.

2. The'ar'rangementbf the planes' so'that each shall cut not onlywith a drawing-stroke, but shall curl the shavings in helices, as specified. 3. In combination with the feeding'carriage and the feedngfscrew, the movablestraddleor sliding block Y and the scroll-cam of the. screw, the same being made to operate together, substantially as specified. i Y

v 4. The tripping-rest, as combined withthe Weighted lever and the feeding-carriage, and used'as specified.
