IMPROVEMENT IN. MACHINES EOE. BUDLING KINDLING-WOOD.

TO ALL WHOM IT MAY CONGERN:

Be it known that we, JOHN RICHARDSON and F. H. STEVENS, of New York city, in the county of New York, and State of New York, have invented certain new and useful Improvements in Machines for Bundling Kinhdling-Wood; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled `in the'art to construct and use our invention, we will proceed to describe it.

Our invention consists in a novel construction of a machine, so arranged as to receive the wood properly prepared, and bind it into bundles suitable for the market, and in which the operations are performed autol matically or wholly by the machine. i l

Figure 1 is a top plan view.

' Figure 2 is a front end view, and V Figures 3, .4, 5,6, 7, 8, and 9 are views -of portions shown more in detail.

In the drawings, A represents tho bed 6 1 frame of the machine, made in any suitable manner. 0n this frame we locate a metal tube, B, having its rear' end brought to a sharp edge, as shown at a of iig. 6, so that whena bundle of wood is shoved into it from thc rcar,the sharp edge will split oi' and separate-such portion of the sticks as may be outside of the tube. This tube' may be made with its sides parallel, except where bevelled off on the inside to sharpen the edge; or it may be made conical throughout a part or the whole of its length, and have its'rear end brought to anedge by bevelling on' its exterior, or partly on its exterior and partly on its inside. Directlyin rear ofthe tube `B is located' a sliding plunger or follower, D, to which a. reciprocating motion is imparted by a crank, b, attached to the driving-shaft G, the follower D being` so arranged as to draw L, back. farenough to permit an endless belt, C, or other wood-carrier, to pass between the follower and the rear l end ofthe tube B for" the purposerof delivering the wood to the tube at intervals, as hereinafter explained. The driving-wheel E of the machine is mounted on a sleeve or hollow shaft, F, which turns loosely on shaft Gr,` which shaft F is intended to be continuous in its motion1 while the shaft G is to operate only at-stated intervals. To accomplish this, a rigid arm, H, is secured to the shaft G, and extends alongside of thewheel E, as shown more clearly in fig. 8. On the side ofthe wheel E is pivoted a dog, c, having one end pressed inward by a. spring, el, this dogbeing so located ,that when the wheel revolves, thc dog', unless tripped by lever d, will engage or lock against the arm H, and thereby cause the shaft Gr and'all its-attachments to rotate with the wheel E and sleeve F. This tripping-lever d is so located that, as the woodcarrier C is brought between the bundling tube B and follower D, it will be thrown aside out of the way'of the dog c, and thus permit the dog to engage with the arm H, and cause the shafts F to revolve in connection with shaft G, thereby imparting motion to the crank 6, which will shove the follower D forward, and drive the wood on the carrier C into the open end of tube B. As soon as this is done, `the lever d is thrown bach to its original position by the spring d1, iig. 1, and as the dog c comes around again itwill be tripped by the end of lever d, thereby permitting the wheel E, with its loose-'shaft F, to go on, while the follower D and the wood-carrier C, together with all those parts driven by the shaft G, remain stationary long enough to permit the bundle of wood that has been shovediuto the tube B to be bound, as hereinafter explained.

There are various ways in which the wood-carrier may be construe-ted and operated. In lig. 1 it is represented in the form of an endless belt, C, having a series of boxes, C1, open at each end mountedr on it, the form of the boxes being either ootagonal,4 as represented in iig. 2, or Otherwise, as may be preferred. In case this form is used, it will be operated by connecting it in any suitableinanner with the driving part of the mechanism. In iig. 3 a different plan is represented, in which we use a box, C2, open at the front and top, sliding back and forth loosely on plate C3 by means of bolts passing through slots al. This plate G3 has a reciprocating motion in a. direction at right angles to C2, it being guided in asimilar manner by slots el formed in the bed'on which it rests, it being operated by a rod,`f, connecting it to un elbowlever,'L, which, in turn, is connected by a rod, L1, to a standard, L2, pivoted at its lower end to the bed A, and against which a cam, I, on shaft F presses, as lshown in lig. 1, a spring, M, serving to restore the parte to their original position as soon as the cam Il ceases `to press on the rod L or standard L2. The wood is placed in the box C2 bythe attendant, whothen shoves it back on plate C3, so that the raised shoulder 0r block a2 shall engage with its outer end, and as the plate C3 is drawn forward between the tube B and the follower D, it carries the box G2 with it, thereby bringing the wood in proper position to be shoved into the tube Bf On the rear side of the box C2 is a projecting pin or arm, a3,

which, as the box is drawn forward, strikes against the endof lover d, throwing its rear end out of the way of ,7 the dog c, thus permitting' the dog c to engage with the arm H, and thus set the follower D in motion t'o shove the wood into the tube B. As soon as the cam II lets the carrier return, which it does beforethe dog c and arm H have made an entire revolution, the lever CZ returns to its original position, and, as the dog c comes to it, it 1- is tripped by the 4end of lever-d, thereby permitting the shaft G and its attachments to remain stationary, while the sleeve F, with its attachments, continuesaits motion.

.After thewood is thus placed in the bundling tube B, the next operation is to bind it and remove itfrom the-tube. For the purpose of binding it, we locate at the front part of the machine a drum or reel, I, carrying .a'zsupply of smallsized annealed wire, c2, which is fed by friction-wheel J up through a steel tube, e3, inserted in the flange of tube B, as shown in fig. 2. This feeding is effected by meansof the bevelled gear A1 on the end of shaft G, connecting with shaft A2, which' latter, by similar gear, A5, drives shaft A", which, in turn, imparts motion to the feedingfwheel J. It is obvious, however, that the feeding mechanism may be operated by any other suitable arrangement of mechanism, the principal requisite being that it sha-ll be so arranged as to feed the vwire only at the proper intervals; and for this reason it is driven. from the shaft Gr, which, as previously explained, operates only when its arm H is engaged by the dog c on wheel E., For the purpose of regulating the feed of the wire e2, a friction-block, K, is pressed against the periphery of the feed-wheel J by a spring, as shownin tig. 2, an additional wheel, Jl, being used, if desired, to assist in guiding the wire to the tube e3. In th front face of the. tube B, on one side, a notch or recess is formed to receive the end of the mandrel M, which is to twist and cut olf 'the wire after it has been passed around the bundle of wood, as will be presently explained. The tube e3, through which the wire is forced by the feeding apparatus, has its upper-end terminatingjust at or slightly above the surface of the lower side ofthe recess in the front of tube B, and has its end hardened arid made sharp on its inner edge, to act as a stationary shear-blade to cut off the wire when the latter is pushed against it, by the turning ofmandrcl M, as hereinafter described. The mandrel M is mounted on the front end of the frame A in suitable bearings, in such a position as to cause its end next the tube'B to rest in the recess in the side of saidstube, and directly'over the end of the small tube c3, through which the wire passes, there being a lnotch or recess formed in the end of the mandrel M for the wire to pass through as it emerges'from the small tube`e3. lThe mandrel M is made hollow or tubular for a portion of its length, asshown in section in iig. 6, and has inserted loosely withinlit a rod, 7L, which has a recess cut in its side near its outerl end, so as to form a head, 2', on its outer end, as shown, which, when drawn back within the mandrel, will clasp and hold the wire tight, the wire passing through the recess in the end of the mandrel, and also that in the side of the'rod h, simultaneously, the mandrel and rod being so arranged that when the rod is shoved out, the 'opening in each for the Imssagel of the wire willbe in line with each other. The rod h is moved out and in by means of a pin,j, inserted rigidly in rod L, and working loosely in a spiral slot cut in' the side of themandrel, as represented in fig. 1, this pin being arranged to strike against the end of a pivoted catch or dog, k, when the motion of the mandrel is reversed, as hereinafter explained. i

On the mandrel M are mounted two loose bevel-gears Ol and 02,'to which-motion is imparted by a similar` gear, O, `on the end of shaft N1, which, in turn, is driven by bevelgcar N on sleeve F, as shown in iig. 1.- On the mandrel, and between the gears O1 and O2', is placed va sliding clutch, P, so attached to the mandrel as always to revolve with it, there being sufficient space between the gears O and O2 to permit the two` latter to revolve without touching the clutch, in which case the gears would revolve in opposite directions, while the mandrel, with the clutch P, would remain stationary, which it does while the wire is being fed in and passed around the bundle of wood in tube B. By throwing the clutch P into connection with 4gear-wheel O1, the mandrel will be made to revolve in one direction, and when the clutch is shifted so'as to engage with the gear O2, then the mandrel will be made to revolve in the opposite direction. This shifting. of the clutch P is effected by ineans of an oscillating arm, P1, pivoted b elow the mandrel at the front of the frame A, as shown in iig. 2, this arm Pl being operated byrhaving one end of its horizontal arm connected to an elbow-lever, Q, shown in fig. 7 detached, and in lig. 1 in place. A rod, R, connects this elbow-lever Q with a standard, R2, pivoted tothe frame Ain such a position as lto be operated by a cam, R3, on the shaft G, as shown in fig. 1. When the cam R3 strikes the arm R2, and, through the medium of rod R, operates the elbow-lever Q, the arm P1 is thereby tipped so as to throwthe clutch P into connection with gear O2, but after the point of the cam Rsullas passed, a spring, m, serves to draw the rod R back again, thereby operating to throw the clutch P in the-opposite direction. and causing itlto engage-with the gear O1..

As it is necessary to 'time the movements of this clutch, so as to reverse the motions of the mandrel M at certain intervals, we applyfor that purpose the devicerepresented in fig. 7. This consists of a disk, R, 4secured loosely to the standard, directly under the outer end of the mandrel M, and having a series of teeth, al, formed .on a part of its periphery, and having also a notch, n2, cut in its edge, as shown. A. spring, Z, has one end attached to the disk R1, its opposite end being coiled around andsecured to the stud or ax'is on which the disk turns. l A cog or projection, n, on the mandrel M is so arranged as to engage with one of the teeth ol at cach revolution of the mandrel, thereby causing the disk to revolve until the notch 'u2 comes opposite thc pin nl on lever Q, when said pin nl fallsvinto the notch n2, vwhichv permits the spring n on' rod R toxtip theshifter or arm P1, Yand thereby throw the clutch into connection with gear Ol. When the cam R3 shoves the rod R forward, the pinnis drawn out of the notch n2, which releases the disk, and instantly thcspring Z returns the disk lt to its original position readyfor a repetition of the operation. By inserting a pin in any of the holes o insaid disl the distance that it will be thrown back by the spring 4can be regulated, as said pin, coming in contact with the standard, will not permit the disk to move further; and in this way the number of revolutions made by the mandrel M. is also regulated, as `it is obvious that it will rotate as many times as there are teeth ol brought into position to behit by toothfn before the notch u arrives opposite the pin al, when the clutch isshifted and the motion is reversed. Whenfthe wire has been twisted, and `thus made secure by the revolving of the mandrel, it must be releasedin order to permit the bundle to be shoved out of the tube B, and this is done by the shifter I" throwing the clutch into connection with gear O, which reverses the motion of the mandrel, and in so doing brings the pin j against the end of the pivoted dog k, which latter permits the pin j to pass in one direction, but stops it when moving inthe opposite direction. `As the mandrel revolves, and the pin j is prevented from revoylving by dog k, the pin is drawn along the spiral slot in the mandrel, thereby pushing the rod z outward and causing the lip z' to release its hold on the wire.

In order to bring the clutch P to a'position:mi lway between the gears Ol and O2 on the mandrel, so as to let the mandrel remain stationary While the wire is being fed' in and passed around the bundleLan eccentric, u,

is placed on the mandrel, and connected by a rod, t, g. 2, vwith the arm c of the shifter I, the eccentric being so located on the mandrel as to movcthe clutch and disconnect -it from gear O'1 at theiinstant the pin j has reached the outer end of the curved slot, the clutch being then in such a position on the mandrel as not to connect with either gear O1 or O2, thus permitting them to revolve loosely on the mandrel, while the latter stands still. In order to adapt the machine to the bundling of wood of'diiferent lengths, We use anvecccntric crank-pin on the crank that -operates the pldnger I), the form of this crank-pin being shown in iig. 1.- By turning this pin in its seatin the arm b, the length of the stroke of the crank may be changed at pleasure. By this -construction and arrangement of parts We produce a machine that requresrbut a single attendant to fill the carrier with Wood and shove it back, when all the subsequent operations are performed automatically at their proper times. We are thus-enabled to perform the labor in a very speedy and efficient manner. i
