To ALL wHoM IT MAY coNoEuN;

:Be it known that I, LUCIUS H. DWEL'LEX, of Dorchester, in the county of Norfolk, and State `of Massa` ehusetts, have invented a new Machine for Separating and Feeding Forward .Rolls or Long Sticks, vto.be af" erwards cut to definite lengths, or otherwise operated upon by machinery, of which'the following is a full, clecm and exact description, reference being had to'the accompanying drawings, ma.king partof this specification, in' which- Figure 1 is a perspective viewof my new machine.

My invention has for its object to produce a machine for separating and feeding forward rolls, long sticks,

ete., to be afterwards cut to definite lengths, or otherwise operated upon by machinery; and my invention consistsin a. vibrating hopper', a-t thehottom of which is a long slot or opening through which the sticks pass to a guide-trough or magazine beneath, whence they are deliveredl one'by one to notched disks, or other equivalent dcvice,'by which they are successively carried to the mechanism which afterwards operates upon them.

To enable others' skilled-in the art to understand and use my invention, I will proceed to describe 'the manner. in whiehI have carried it out. l

In thesaid drawings, which represent a machine for cutting curtain rolls and otllerarticles to 'a definite length, A is the framework, in suitable bearings, in which runs ,the driving-shaft B, which carries at one 'end the grooved pulley 0, from which motion is communicated, by means of a belt, d, tothe small pulley b on the end of the shaft or arbor D, which carries the cutting-offsaws E. F is a hopper, of the formy seen in fig. 1,

thejournals c of which rest in bearings at the top of the framework. To the outer end of oneof these journals c is secured an arm, d, the lower end of which is pressed against the periphery of the pulley C, by means of a. spring', e, secured to the framework atf; and this arm d, is-vibrated against the resista-nce of Vthe spring e by cams or projections, fg, on` the pulley C, so as to give the requiredI motions to the hopper. In the bottom ofthe hopper F is out a long siot or opening, h, through which the wooden rollsor sticks pass one by one-successively to a guide-trough or maga-zine, G, which is attached to the framework immediately beneath the hopper. A portion of one side of this tro-ugh Gis cnt away s o as to aiord-access to it in case it shouldbecome'obstructed or clogged; and at one end isplaced 'an inclined. strip, 10,. gs. 8, 4, and 5, which serves as a guide to bring the ends of the sticks into the required position on arriving-at the bottom of the magazine. Directly underneath tho 'magazine Gr are two disks or carriers, vH I, secured to a horizontal shaft, J, havingits bearings in the framework A; and in the peripheryoivthese disks, opposite to each-other, are cut n Aseries of notches, z', at short distances apart, into which thesticks fall from the-magazine afs-the disks are revolved.

I will now proceed to describe the manner in which these disks are revolved,.f0r the purpose of feeding forward-thc sticks to the saws E E. K is an arm which is pivoted to the end of driving-shaft B, and carries a bearing,. 7', in which revolves a short shaft, 11, which carries at one end a worm-wheel, L, and at the opposite end a bevel-wheel, M, which engages with a bevel-wheel, N, on'thc end of the ldriving-shaft B. The wor-m1 wheel L engages with a toothed wheel, O, and' thus, 'through the( connections explained, the disks H I are revolved slowly ns required. P is a crank, the portion cof which is made hollow andiits over a stud or pin, l, projecting from the framework A. At the inner end oi" this portion k-is formed an eccentric, in, figs. and 8, which ts'into a slot, n, in the ndof the arm K, and thus,'as the crank is turned, the arm K `is lowered or raised to throw the worm-wheelL in or out o't4 gear with the wheel 0,' tostart or stop the feeding-disks H I, as may be desired. .On the end of the stud lis cut u. 4scnew-thread, which iitsinto a corresponding screw-thread on the inside of the portion k, and thus'as' the crank is turned in the direction of the arrow, iig. 2, tolower the arm and throw'the worm-whcclv'L into gear with-the wheel O, the shouldn-a; `tig. 7, of the portion k is caused at the same time to 'press the arm 'K-'against the framework A'and clamp it tightly in place. Instead casse 2 of the portion k of the crank being made hollow and turning on a' stud', :xs-shown, escrow-thread may be cut on the end f the portion c, which may be screwed into the framework, the eccentric b'eing formed justin front of Vthe screw-thread, when the operation will be similar to ythat above described.` Q are ,curved :ir-ins proiecting out from the magazine G over the disks-H I for the purpose of preventing the sticksfrom being thrown out oi.' thenotches t' beforereaching the sawsE E', thc radins ofthe curvature of the under side of these arms being a little greater than that ot'rthe disksfand thc arms being placed a sufl'icicnt distance above the disks to allow the sticks in 'the notches t' to pass freely beneath. p is u. strip or plate of sheet metal which'is attached to the magazine G, and is 'bentso as to form an incline,-as seen in'g. 5, against which the ends of the sticks strike as they are fed forward by the disks H I, thus moving the sticks longitudinally into such a. position as toiusure both ends being cut olf by thesaws E E. The sticks are held firmly in the notches in the disks H I, and prevented from turning while being operated upon by the saws by means of a spring, r, which is secured to the'framework at s, and carries at its outer enda roll, qi, which is so placed that each of the sticks, 12, will pass underneath it just before commencing to be operated upon by the saws vE E'. If preferred, the roll q may be dispensed with, and the spring only be employed to hold'the sticks; After the .sticks are cut to a definite length by the saws, they are carried round by the disks until they pass out from under the eurvedarms Q, when they fall out of the notches z'.

I will now describe the-manner in which the distance between the saws E E. is varied so as to cut sticks of different lengths without removing the shaft D from its hearings'. tu, are collars, which are placed one on each side of, the'saw E, and are recessed out at yg. 6. R,l is a'short sleeve or collar, which is made in two halves, and its over the shaft D,A one end entering the recess 13 in'the collant, whilst the opposite end ts-into a; recess, 14, in a screw-nut, v, which'works on a sere\"-f-threat l cut on the shaft D, and by turning the nut v the saw E is held rmly in place on the shaft. Whenit is desired 'to cut sticks of a greater length,V the nut 1J is uuscrewed until the two halves of the sleeve R are free to be removed, when the saw E, with its collars tu,

may be moved longitudinally until there is suicicnt room to place the sleeve R between the collar u and the shoulder w on the vshaft D, one end ttin'g in to a recess, 15, in the shoulder tu, while theA opposite end enters the recess 13 in the collar it; the screw-nut 'u is then tightened up, and the whole secured tightly in' place; and it 'will thus be seen that the distance between the saws may bc readily varied'as required, without removingthe nut 21 from the shaftD or the shaft from its bearings. By the employment of one sleeve R only, as above described, the sawE may be secured in'l't'wo 'dilerentpositions on thevshaft'D; but by using anumberof similar sleeves of Ydilereht lengths,'the distance betweenthe saws may be varied as. desired. The disk H slides on the shaft J with' a spline,'and is iliade adjustable longitudinally ori-the shaft J, so as to correspond to the position of the saw E, by means Aof a pin, '16, which fits into holes made to'receive it in the shaft .T, as it is desirable that thelstick be supported atapoint near where it'is to be cutolf. I t is evident that the sticks, after-passing' out of the magazine Gr, may be: bored out at their ends, or otherwise operated upon by machinery, 'instead of being eut to definite lengths by saws, as above described, and that other articles besides wooden sticks bev in u. similar manner separated and fed forward, tobe afterwards operated upon by machinery; without departing from the spirit of'my invention and instead `of they carrying disks AH I some other mechanical device may be employed, if preferred, to receivc'the sticks, after they leave the' magazine. I Operations The parts being in .the position represented in fig. 1, the operator `fills the hopper with the wooden rolls or sticks, which are to be cut to definite lengths for curtain rollers 'or other purposes, ,andthe machine being 'set in operation, the vibrations of the hopper cause the sticks to pass one by one successively through the slot L` into the guide-trough or -magazine G, from which they fall on toA the revolving disks H I, entering tho notches as they arrive beneath the magazine, the sticks being guided and broughtinto their proper position onfarriving atthe bottom of the magazine by means of the incline 10. "The sticks are nowcarried round by the disks under thc curved arms Q, the ends of the sticksstriking against the inclined guide which moves' the .sticks longitudinally .in' the notches e', and brings them into a position to insure both ends being cut o by the saws E E'. Just before eadh stick is hrought'into contact with the saws it passesy under-thc Vroll q on the end .of the I spring r, which holds it rmly-in the notches z', and prevents it from. turning while the cuds'are being cut'oi,

after which it is carried around oy the revolution of the disks H l until it passes out from. under the arms Q and-arrives into a position to fallby its own-weightnu't of the notches if. Suitable cutters may, if rn'ci'erred,A

be substituted for thc saws E E. By placing the trough or magazine G between the hopper and thenotched disks er carriers, instead oi"4 allowing the sticks to fall directly fro'mthe liopperjinto the notches z', a continuous supply of sticks is insured, as in the event of tlie slot h,.becoming temporarlly-cloggcd or obstructed it will be cleared by the vibrations; of the hopper, so as to allow the sticks to pass-into the magazine before it becomes empty, thus .avoiding any lossof time.

Claim.

What claim as my inventionfand. desire to secure by Letters Patent, is

The arrangement ot' the vibrating hopper, I, which .receives the sticks in mass, with magazine 4Gr, which,

arranges them in a single column so that they may be delivered one at a time tov a carrior'orfholderthat concys them `to thc tool or tools that are to u-fterwardaoperatc upon them, substantially as described;

I also claim zii-'ranging within the magazineG a guide, 10, at` one of its ends only, which guide arranges the -sticks in a lipe at that c ndof the magazine, and-allows all the inequalities in their lengths toproject at the opposite end, substantiallyA as described.

I'also clai'm the spring r, with its roll q., in' combination with the carrying disks H, I, substantially us and for the'purpose described.

I also claim the crank P, with its eccentric m, in combination with a. slotted arm, K, and so arranged with a. screw that, when turned in a. direction to throw the worm-wheel L into gear with the wheel 0, it will clamp the arm K firmly in piece, substantially as described'.

I also claim making the saw E adjustable on its arbor-D by means of the split collar or sleeve R, screw-nut v, with its recess 14, and recessedv collars t u, substantially 'as set forth.
