KlNDLlNG-WOOD BUNDLER.

SPECIFICATION forming part of Letters Patent No. 562,722, dated June 23, 1896.

Application filed October 5, 1895 Serial No. 564,729. (No model.)

To all whom it may concern:

Be it known that I, DARWIN A. GREENE, a citizen of the United States, residing in Brooklyn, Kings county, in the State of New York, have invented a certain new and useful Improvement in Kindling-VVood Bundlers, of which the following is a specification.

I employ the ordinary construction of the parts which act on the wood, as set forth in the patent to me dated February 26, 188i, No. 29l,125. The invention relates to the means for operating those parts. I operate by a cam or wiper carried on a revolving shaft, with mechanism for revolving such shaft a1- ternately in opposite directions to open and close the compressor while the driving-shaft rotates continuously and uniformly in one direction. In my machine set forth in the said patent the compressing is effected by the force of the hand or foot of the operator. I have in my patent dated March 16, 1886, No. 337,9 l6, shown a steam-cylinder attached di- Fc'dtly to each bundler, with connections for supplying steam and properly distributing it to operate the parts. By my present invention these cylinders and attachments are dispensed with and the power is received from a line-shaft turned continuously in one direction by a steam-engine or other suitable source, and by ordinary means, as a belt, communicating a continuous rotary motion to a shaft in my machine, which has an approximately volute cam or wiper, the turning of which in one direction closes the parts and compresses the bundle, and the turning of which in the opposite direction opens the parts and releases the bundle. I provide means, controllable at will, for turning such shaft alternately in opposite directions. The compressing mechanism is thrown out of engagement automatically when the proper degree of compression is attained.

The machine avoids the expense of constructing and maintaining so many steamcylinders, valves, 850., and avoids the heat incident to the use of steam-cylinders in such close relation.

The accompanying drawings form a part of this specification and represent what I consider the best means of carrying out the invention.

Figure 1 is a side elevation showing the en- Fig. 2 shows the main portion v wise position of the short pieces of wood being bundled, and A is the cradle, a stout casting properly formed to shape the lower side of the bundle, and adapted to rise and sink to effect the compression and release of the wood.

0 O are straps, shown as double, but which may serve successfully single, adapted to match to the upper side of the bundle and to hold it against being lifted under the strain received from below.

D is the operating-lever, and E h the toggle-links actuated thereby to forcibly lift the cradle at each operation. The motions are controlled by two foot levers or treadles, which are to be depressed alternately.

The lever D controls the compressing motion. It is equipped with an antifrictionroller, which is acted on by an approximately volute cam or wiper I, fined on a shaft 1. The operation of the toggles is effected by making a nearly-complete revolution of the shaft I alternately in one direction and the other. When the motion in either direction has progressed to a certain point, it is autovInatically arrested, and the machine is left in that condition until the workman depresses the other foot-lever and thereby initiates the motion in the opposite direction.

J is a shaft turned by the action of a belt on a pulley. (Not shown.) This gives a constant and sufficiently strong rotation to a small gear-wheel J The revolving of the shaft I and the attached wiper I in the direction to compress the wood is effected by spur-gear, through the aid of the large gear-Wheel 1 which is acted on at the proper time by a small gear-wheel H, which turns loosely on a stud G, carried on a lever G, which latter is capable of being turned on the shaft I as a center. The wheel H is constantly in gear with the wheelI and is thrown into and out of gear with the driving-wheel J as required. The lever G is depressed at the required times by the action of a link L, which connects to the foot-lever M, turning on a fixed stud A, and which is actuated by the foot of the attendant. The opposite end of the foot-lever M carries a counterweight M, which is suliicient to promptly turn the foot-lever in the direction to lift the link L and its attachments and thereby carry the gear-wheel H out of engagement with the driving gear-wheel J When the operator depresses the foot-lever M and raises the weight M, it brings the gear-wheel H into engagement with the driving gearvheel J and the Wiper I is revolved in the direction to raise the lever D and straighten the toggles E E thereby raising the cradle A and compressing the wood. lVhen this operation has proceeded to a sufficient extent, a dog I on the inner face of the wheel I touches a properly-rounded part near the upper surface of the weight M and depresses it forcibly, thereby compelling the lifting of the foot-lever M and disengaging the gear-wheel H from the driving-wheel J and the motion of the cam I stops. The machine may remain in this condition for any period, holding the wood tightly compressed. During this period the string or other confining means, as a wire, is properly secured around the compressed bundle.

The direction of the force received by the movable wheel H from the constantly-revolvin g wheel J 2 when it is lowered into engagement therewith and the direction of the force given out again to the large gear-wheel l tend to draw the gear-wheel H too deeply into engagement with the teeth of each of these wheels. The tendency to bottom the gearteeth in the large wheel I is well resisted by the lever G, which, while it is free to rise and sink, is obviously rigid to resist end wise compression.

I provide special means for resisting the tendency of the wheel H to crowd down and bottom the teeth in the gear-wheel J and I make such means adjustable. These consist in the screw M tapped into the foot-lever 1 M and extending downward therefrom, held firmly in any position in which it may be adjusted by aid of a jam-nut M The head of this screw M serves as the stop by striking a fixed object below and arresting the further descent when the lever M has been depressed to a proper extent by the action of the foot of the attendant. As shown, this screw will strike the floor, but it may be preferable to arrange it to strike the iron foot of the machine. IVhen for any reason it is desired to allow the footlever to sink a little lower and the teeth of the wheels to engage nut M again tightened. The compression is relaxed by turning the shaft I and its attached wiper I in the opposite direction. This is controlled by a foot-lever or treadle P, turning on a fixed center and carrying a link Q, which bears on a stud Q. a smooth frictionwheel R.

K (see Fig. 2 is a constantly-turnin g friction gear-wheel carried on a shaft K. It receives motion from the shaft J through the gears J 2 K (see Fig. 1,) and consequently revolves in the opposite direction to J. The smooth friction-pulley K serves to impart, through its continuous rotation, a partial rotation to the cam-shaft I in the opposite direction when it is required to relax the compression and to receive the wood for another bundle.

The peripheries of the several frictionwheels are preferably grooved and ridged. The depression of the foot-lever P presses the smooth wheel R into frictional engagement with the wheels K and 1*, so that the motion is communicated frictionally to the shaft I, turning it in the direction to permit the lowering of the lever D and deflection of the toggles E E and the lowering of the cradle A to release the bundle.

The cam or wiper I has a concentric surface at its highest point, so that the roller is carried thereon without any disposition to turn the shaft in either direction.

When the operator depresses the foot-lever P and brings the friction-gearinginto action, it turns the shaft I, with its attached wiper I, in the backward direction, this motion being not only without obstruction, but aided by the expansion of the wood, which acts on the volute surface of the wiper to promote the motion. I provide a stop which arrests the reverse motion at the right point. W is such a stop, faced with wood V held in a dovetail groove on the workin g face, so that the blow of the point of the wiper is not against iron, but against wood, and is practically silent. This stop IV is capable of turning on an axis 11', supported on the frame, and it is raised by the contact of the lever D, so that it offers no obstruction thereto. On the descent of the lever D it falls back into place again.

It will now be understood that if the foot of the attendant is allowed to rest too long on the foot-lever M with the apparent intent to make the wiper I perform more than one revolution, the cam I carried by the shaft I, touches the rounded top of the lever near the counterweight M and actively depresses it, thus causing the counterweight to serve as a tripping-piece, compelling the lever M to turn and disconnect the gear-wheels H and J This insures that the wiper shall not revolve beyond the proper extent. hen the relaxing motion is completed, the back of the stop IV bears fairly against the frame and the stop stitfly resists any further turning of the wiper in that direction.

P isa screw tapped into the counterweight IIO P, which lifts the treadle P. This screw P strikes the foot of the machine. It may be adjusted to regulate the height to which the treadle P will rise.

P is a spur cast on the upper side of the lever P in the position represented. It receives the friction gear-wheel R and supports it in about the correct position when not in use. This wheel should have freedom to find its bearings equally between the friction gear-wheels K and I when the treadle is depressed, and this part of the apparatus is brought into action.

S is a piece of metal (see Fig. 2) centered loosely on the shaft I, alongside of the wiper I and having a crosspiece S, one end of which carries a screw S which rests on the framing and holds the piece up strongly. The other end of the cross-piece engages under the lever D and when it descends supports it. The termination of the descent of the lever D and consequently of the cradle A controls the size of the space provided for the wood. If we want more room for the wood, the screw is turned to let the part S and consequently the lever D and the cradle A descend lower. A jam-nut holds the screw firmly set. An arm S extends laterally from the lower edge of the piece S and engages under a lip on the framing. (Shown in dotted lines in Fig. 2.) This gives all the freedom required for adjustments and prevents the piece S from ever being raised too high and perhapsthrown quite over the shaft I by the friction of such shaft.

The tightness with which the bundle is compressed may be varied by turning a right and-left screw T, which intervenes between and connects the cradle A,with the crosshead or vertical guide-block U below.

The block U, which serves as a cross-head, receives the action of the toggle, the upper; member E of the toggle entering a cavity in its base and being connected by a pivot-bolt U. (See Figs. 2 and 3.) This blockis cast or turned cylindrical, and the slideway in the base of the head in which it reciprocates is correspondingly cylindrical, and of such size as to make an easy fit. The right-and-left screw T connects this block and the cradle A and serves not only to adjust the height of the cradle relatively to the block and thus to determine the degree of compression of the bundle, but also serves by its central position and its freedom of turning to allow the head and its attachments, including the cradle and strap, to be turned in any required position to accommodate the work.

The cylindrical form of the cross-head and the corresponding cylindrical hole in which it turns are among the easiest forms to produce, requiring simply turning and boring. This form of cross-head and bearing therefor allows the parts to adjust themselves and to automatically maintain an easy and durable bearing. They make an easy fit. However, the head A and the cradle A and its connections may be partially revolved, so as to stand in various positions, saving expense and trou ble in adjusting the moving parts of the machine. It is desirable sometimes to thus turn the head of the framing and its contents so as to hold the parts in a different position. The head A is made in a separate piece from the main body A and is secured thereto by flanges A A and bolts A. There may be eight of these bolts, equally spaced, and by taking them out and turning the head and replacing them, the head may stand in eight different positions. By increasing the number of equally-spaced bolt-holes and bolts the adjustment may be made still finer. It will be understood that with each such change of position of the head-flange A there will be a corresponding change of position of the eradle A and strap G. This condition also al' lows a complete change of the head when such becomes desirable for any reason,taking away the present head with its contents and substituting another, which may be merely one less worn, or one of a different size or form. It is important that the flanges and bolts shall match and that the cradle and other parts shall properly connect to the operating mechanism below.

Modifications may be made without departing from the principle or sacrificing the advantages of the invention. I can use antifriction-gear for lifting the cradle, or toothed gear for depressing it. I prefer the spur-gear for the closing of the compressor, for the reason, among others, that such gear gives great force in the rotation induced, while requiring but little pressure to effect the engagement; and I prefer the friction-gear to effect the lowering of the cradle, for the reason among others that if by any mistake both foot-levers should be depressed at once no mischief would be induced, the friction-gear yielding to the imperious requirements of the spur-gear. 7

An efficient guard should be used to shield the gearing from being injured by wood dropping accidentally into it.

I claim as my invention- 1. In a wood-bundler the wiper I, in combination with connections D, E, E for operating a compressor thereby, and with two sets of mechanism, one set adapted to rotate such wiper in one direction and thus to close the compressor, and the other set to rotate the wiper in the opposite direction and open the gompressor, all substantially as herein speci- 2.
