MACHINE FOR BU ND LING KlNDLlNG-WOOD.

SPECIFICATION formingpart of Letters Patent No. 282,381, dated July 311, I883.

' Application filed April 2,1883. (No model.)

To all whom it may concern-.-

Be it known that I, MYRON J. SHAW, of

Williamsport, Lycoming county, in the State of Pennsylvania, have invented certain new and useful Improvements in Machines for Bundling Kindling-Wood, of which the following is a specification.

My invention relates to that class of machines for bundling wood andsimilar mate- IO rial in which a compartment for holding the wood to be packed-is combined with a follower or presser, by which the wood is pressed i into as small compass as possible, and is thus held until the bundle is tied.

My improvements have reference to the means for operating the presser or follower,

and to the means for operating the ejectorthatis to say, the device which throws out from the machine thebundle after it has been completed. I operate the presser directly by steam-pressure, connecting it to the pistonrod of the steam-piston, so that it shallmove in unison with the piston; and I provide the reciprocatory piston-rod with a rotary collar or tappet, which is operated on by cams in such manner that when-the piston-rod recedes,

so that the presser 'is caused to release the bundle, the collar or tappet will first act on the ejector mechanism to cause the, same to eject 0 the bundle from the machine, and will then release said mechanism and permit it to re sume its original position.

The nature of my invention and the manner in which the same is or may be carried into ,5 effect can best be explained and understood by reference to the accompanying drawings,

in which I have represented a machine .em-

bodying my improvements in their preferred form. Figure 1 is a vertical central section of the machine from front to rear. Fig. 2 is a like section in plane at right angles to the plane of section in Fig. 1. Fig. 3 is a plan of the machine. Fig. ,4 is a perspective view of the 5 collar or tappet hereinbefore referred to, to,- gether with its operating-cams and the lower end of the lever that carries the ejector.

A is the frame of the machine, which carries the working parts. The compartment or receptacle for holding the wood to be bundled is composed of two steel straps, B, and the presser or follower O. The straps form the sides and top of the compartment. They are placed about three-eighths of an inch apart, so as to leave between them a slit or opening,

a, for the passage of the cord or wire used to tie up the bundle, and their lower ends are j V bolted fast to the top of the frame A. The

inner edges of these strapsare in practice rounded or beveled. 6o

c in the frame A and form guides, which pre- 7 0 vent the presser from turning or getting out of place as it moves up and down.

The piston-rod D extends down through a stuffing-box, (Z, and isattached to a piston, E, which works in a steam-cylinder, F, formed in 7 5 the base of frame A. l

On one side of the steam-cylinder is a steamchest, G, in .which is a slide-valve, c, which governs the admission and discharge of steam to and from the cylinder F through steamports f f and exhaustport g. The valve is provided with a stem, h, which passes out from the steam-chest through a suitable stuffingbox, 2, and is connected to a-hand-lever, H, by

means of which the operator shifts the valve 8 5 from one position to -the other. 7 l

The operation of the parts thus far described is as follows: They are shown in Figs. 1 and 2 in the position which they occupy when the machine is ready toreceivewood to be 0 bundled, the piston is in its lowest position, live steam being admitted above it through port f, and port fbe'ingin'commur ication with exhaust -port 9 through the valve 6.

While the parts remain in this position the 9 5' pieces. or sticks of wood to be bundled are put into the compartment or receptacle and rest upon the presser or follower G. A piece of cord having first'been entered throughthe. slit or opening a, so as to extend across the .2 amt .shifts the valve 0, so as to permit steam to enter the cylinder below the piston through port f, and at the same time to permit the steam already in the cylinder above the piston to exhaust through ports f g. The piston at once rises, and moves with it the presser O, which, as it ascends, is forced against the wood, so as to bring the latter into the condition of a compact bundle. \Vhile the wood is thus held by the upward pressure of steam acting upon the follower 0 through the intermediary of the piston and piston-rod, the operator gathers up the ends of the string, carries them up over the bundle through the slot a, and ties them tightly. This completes 'the bundle-tying operation. The valve is then shifted, so as to cause the presser to descend,

and the bundle of wood is thus released and can be removed from the machine.

In order to automatically eject the completed bundle from the machine, I make use of the following arrangement of parts: At the rear of the compartment is a disk, I, which is capable of sliding in the compartment from front to rear, and also forms a backing for the compartment. This disk or plate Iterm the ejector. It is supported by a stem, I, mounted and adapted to slide horizontally in the bearing J on the back of the frame, and it is connected by a link, K, to a T-lever, L, pivoted at j to the frame of the machine. The outer horizon tal arm of this lever carries aweight, k, which tends to draw back the ejector and hold it in the position shown in Fig. 1. The other hori zontal arm, 75, of the lever projectsinwardly toward the piston-rod D, so that its inner end will proj ect into the path of a collar or tappet, Z, on the piston-rod. This collar is provided with a peripheral notch or opening, 112, on the side adjoining the T-levcr, and is capable of limited rotary movement on the piston-rod, so as to throw this notch into and out of register with the endof arm k of the lever L, as desired. These movements of the collar are antomatically effected during the rise and fall of the piston-rod by means of cams or inclines n n on the upper and lower faces, respectively, of the collar, which are adapted to work against corresponding stationary cams or inclines, 0 0, on the frame A. The cams no operate, when the piston has about completed its descent, to throw the notchm into line with arm 7c, in which position they are shown in Figs. 1. and 2. WVhen the piston-rod rises, the collar remains in this position until the rod nears the upper end of its stroke, at which time the cam end, comes against cam 0, with the effect of partly rotating the collar in a direction opposite to that in which it was before movcdbyn 0. Consequently when the pistonrod descends, the solid portion of the collar is opposite arm and thus when the downward movement of the rod is nearly completed the collar, as indicated inFig. 4, will bear upon and depress the arm k, with the effect of throwing forward the ejector, and the latter in this way will be caused to eject the completed bundle from the machine. By this time the cams n 0" will have come together, and by their action will have rotated the collar in a direction to bring the notch m opposite to arm is. The ejector-lever L consequently is released from the control of the collar, and the weight k at once returns the ejector to its normal position.

It is manifest that in lieu of forming a pcripheral notch, m, in a collar the latter may be made witha toe or lateral projection, which can be brought into and out of the path of the ejector-lever with the same result, or that the collar may be otherwise formed for the same purpose.

Having described my improvement and the best way known to me of carrying the same into effect, what I claim as new and of my invention is 1. In a machine for bundling wood, the combination of the wood-containing compartment .or receptacle, the reci'procatory steam-piston and its cylinder, and the presser or follower adapted to slide in said compartment and connected to the piston, so as to move in unison therewith, substantially as hereinbefore set forth.

2. In a machine for bundling wood, the combination of the steam-cylinder, the reciprocatory piston therein, the piston-rod connected to and moving with said piston, the wood-con- W taining compartment or receptacle, and the presser or follower mounted on and carried by the piston-rod, substantially as and for the purposes hereinbefore setforth.

3. In a machine for bundling wood,the steamchest, the steam-valve, and the valve-shifting lever-handle, in combination with the steamcylinder, the reciprocatory piston therein, the v piston-rod, the presser or follower carried by and moving with said piston-rod, and the woodcontaining compartment or receptacle, forj oint operation substantially as hereinbefore set forth.

4. In a machine for bundling wood, the combination, with the ejector and the ejector-lever, of the piston-rod, the rotary notched or equivalently-formed collar thereon, and cams on said collar and frame of the machine, re spectively, whereby the solid portion of the collar is brought into and out of the path of the lever by and during the; reciprocatory movement of the piston-rod, substantially as and for the purposes hereinbefore set forth.
