6, but in views of horizontal and vertical 3 is the bed-plate of the machine, made of 50 section. Fig. 11 is a separate top View of the cast metal and having legs 4: 4. 4 4, which too rest upon the transverse runners 1 1 and are secured thereto. The bed-plate 3 is provided with a central circular opening, 5, and surrounding this opening is a circular platform, 6. (Shown in vertical section in Figs. 2 and 6.) The top of this platform 6 is above the general level of the bed-plate 3. In this opening 5 of the bed-plate 3 turns the extended hub 7 of the chain-wheel S, the body of such chainwheel resting upon the circular platform 6 of the bed-plate 3 and projecting slightly beyond the outer line of said circular platform 6. The object of this circular platform and projecting chain-wheel feature is to protect the lower horizontal and vertical bearings of the chainwheel in the bed-plate 3 from any dirt or sand that may be carried into the machine by the chain; and with this arrangementof the parts it will readily be seen that the dirt or sand would drop on the bed-plate 3 too far below the point at which it must enter to enable it to get into and grind or cause too much wear of the aforesaid bearings.

The chain-wheel S has pockets 9 for the in ner portion of the horizontal links of the cable chain, and pockets 10 for the vertical links of the chain. The chain-wheel 8 is also constructcd with projecting hub 11 on its upper end, and with an opening, 12, down through it, in which opening the keysbank 13 of the operatinglever socket 14 rests removably. The lever-socket 14 receives the inner end of the operating-lever 15, to the outer end of which the horse or team is attached that operates the machine. The sides of the leversocket 14 are preferably made parallel with each other, and a portion of the operatinglever made with parallel sides also, to enable it to fit the socket and render it capable of be ing shortened or lengthened, as desired, by pushing it farther through the socket or withdrawing some, the lever being held securely in the socket at the desired point by means of a set-screw, 16, or by a pin passing through the lever-socket casting and projecting into a hole or an opening provided in the lever to receive it; and such holes or openings could be provided at di fferent points in the lever,as desired.

The bed-plate 3 is provided with two upwardly-projecting hollow studs, 17 17, and upon these studs 17 17 rests the top plate, 18, having a central opening, 19, which fits over the upper hub, 11 of the chain-wheel 8 and forms the upper bearing for such chain-wheel. The top plate, 18, is securely held in position by means of the two bolts 21 21 passing upwardly through the studs 17 17 and the side projections, 22 22, of the top plate, 18.

Between the bed-plate 3 and top plate, 18, is situated the horizontal chain-guide box, which is composed of two halves, 23 2:1, and provided with a sufficient number of lugs 25, by which the halves are bolted together. The

parts

23 and 24 form a box, which surrounds the chain-wheel and conforms to the contour of so much of the chain as projects from the wheel, serving to hold the chain in position in the pockets of the wheel, so the links cannot work out of operative connection therewith or become cramped thereon.

In front of the chain-wheel the chain-guide box has two forwardly-projecting guide arms, 26 26, which entirely inclose the chain, having vertical and horizontal grooves to accommodate the vertical and horizontal links ofthe draft-chain.

The openings at the outer ends of the guidearms 26 26 are flared somewhat, so that the links will run smoothly into and out of such guide-arms without catching. These hollow guide-arms 26 26 preferably project obliquely to each other. although we could make them to project parallel with each other. These hollow guide-arms serve to conduct the chain onto and off of the chain-wheel.

The upper and lower halves of the horizontal chain-guide box are exactly alike, except the lower half has supporting-legs 27 27 located around its central opening, such supporting-legs 27 27 27 27 being preferably of the shapeshown in Fig. 8. \Vhen thelowerhalt'of the horizontal chain-guide box is in its proper position on the bed-plate 3 the aforesaid supporting-legs rest thereon. The open spaces between the supporting-legs permit any sand or dirt that may have dropped from the wheel above to work outwardly from it, and when the machine is in operation the lateral movements of the horizontal chain-guide box, when provided with supporting-legs 27 of theshape shown in Fig. 8, serve to push outwardly from the chain-wheel the sand or dirt that may have dropped from above, thus keeping it away from the lower bearings of the chainwheel, and also the bearings of the supporting-legs 27011 the bed-plate 3.

The chain-guide box is held down in position by the top plate, 18, but is capable of swinging freely from side to' side on the bedplate 3. This swinging movement is limited by the striking of one or the other of the chainguide arms against one or the other of the studs 17 17. The hollow guide-arms 26 26 also serve to conduct the draft-chain clear of the machine and assure the correct arrangement of the links of the draftchain before they reach the chain-wheel. The swinging movement of the horizontal chain-guide box allows the guide-arms to adjust themselves to any change in the line of draft of the draft or pull chain with a more gradual movement of the machine and less friction. The anchor-bail 28 is secured by the bolts 21 21, that pass up through the studs 17 17, the eyes of the anchonbail 2S, and the top plate, 18. To this anchor-bail we attach the anchor-chain 29. (Shown in Fig. 23.)

The draft-chain 30 is preferably of what is known as the stud or brace link pattern, the links having metal studs or braces 31, extending crosswise inside of the links. \Ve, how ever, can use the ordinary short-link cable chain, if desired, for a draft-chain.

In some cases we use the pattern of chainwheel shown inFigsrlO and 5, which wheel has "pockets 32 forthe vertical links of the groove, 33, to receive the inner portion of the horizontal links of such chain. When we employ a wheel of this pattern we use a chainstripper plate, 34, (shown in Figs. 5 and 7,) to

' prevent the links of the draftchain from following the wheel around past the guide-arms and clogging on the delivery side of the chainwheel. When the chain-stripper plate 34 is used, the horizontal chainguide box is provided with an opening, as shown in Fig. 5, to receive the chain-stripper plate 34, which is held in position in front of the chain-wheel between the two halves of the horizontal chain'guide box by means of holes 35 and studs on each of the said guide-box halves, which studs project slightly into the holes 35 in the chain-stripper plate 34. This chainstripper plate 34 projects into the groove 33 of the chain-wheel and conforms thereto, and

' has two tapering fingers, 36, which follow the groove around to the sides of the chain-wheel. These fingers 36 strip the chain from the wheel and force the horizontal links of the draftchain outwardly, compelling the links to pass smoothly into the hollow chain-guide arm on the delivery side of the machine without possibility of their becoming cramped or clogging.

The chain-stripper plate 34 swings with the chain-guide box and guide-arms, so as to act uniformly therewith. y

We sometimes use a chainstripper plate with the chainwvheel 8; but in such case the chain stripper plate is made ofthe same shape, but shorter, and does not project into the chain-wheel any farther than the outer ends of the spurs or partitions 37, between the pockets 9 for the horizontal links, will permit, so that thestripper-plate will not interfere with the chain-wheel turning freely. When the chain stripper plate is used, the

ehain-guide-box halves are provided with the opening to receive it, and the holes and studs, same as hereinbefore described, when the chaiustripper plate is used with the chainwheel, Fig. 10.

\Vhen the operator hitches high on the body of a stump, and when the jack 38 is used, the

draft-chain sometimes rises too high to permit the operating horse or team to cross it easily. To meet such difficulty we sometimes use a modified lever-socket, 39, Fig. 6, having a round tapering shaft, 40, which projects downwardly into a central circular opening,

41, in the chainwhee], adapted to receive andfit it, the horizontal projecting part 42 of through the hub of the chain-wheel, and also 2 through the shaft of the lever-socket, which, draft cable chain, and around its center a when the lever or sweep is operated, causes the chain-wheel to turn with it, and when pin 45 is withdrawn the lever can turn without cans: ing the chaiuwheel to turn. Through the collar of the top plate, 18, is also provided a horizontal hole or/openin'g, 46; and on the same horizontal plane a number of horizontal holes or openings, 47, are made at different points around the hub of the chain-wheel to receive the pin 48, which passes horizontally through the opening or hole 46 in the collar of the top plate '18, and through one of theholes or openings 47 of the hub ofthe chainwheel, but in this case not into or through the lever-socket shaft 40. When the machine is in operation the pin 45 is in position, as shown, and the pin 48 is withdrawn, and if draft-chain on a high hitch rises too high for the horse or team to cross easily,the pin 48 is inserted as soon as one of the holes 47 in the hub comes in line with the hole 46 in the collar of the top plate, 18. Inserting the pin 48 prevents the chain-wheel from turning backward and holds all advantage in the pull that has been gained. The team or horse is now detached from the operating-lever, and after withdrawing the pin 45 the lever is turned beyond the draft-chain and until the holes in the socketshaft 44 come in line with the holes that match in the hub of the chain-wheel. Then the pin 45 is inserted and the team or horse led around the rear of the machine and again attached to the lever, the pin 48 being withdrawn,so as to permit the chain-wheel to again revolve wit-h the lever.

The holes or openings 47 in the hub 43 for the pin 48 should be larger than the hole through the collar of the top-plate, 18, to en able the operator to more easily withdraw the -pin 48 upon starting the team or horse.

The operation described can be repeated as often as a high-draft chain renders it necessary.

, In some cases, instead of using the pin 48 for view in Fig. '19. Thislocking-plate 50 is preferably made of metal, and'hasaslot or an opening, so it can be placed on a vertical link of the draft chain at the mouth of the hollow guidearm 26, Figs. 18 and 19, through which the chain discharges. When thus applied, the locking-plate 50 prevents the draft-chain from passing back through the machine when under heavy strain and with horse or teamdetached, and also holds the wheel from turning backward while withdrawing the pin 45 and turning the lever beyond the draft-chain, as hereinbefore described.

We could dispense with the pin 48 and the locking-plate 50 also, substituting therefor a ratchet on the hub of the chain-wheel and a pawl located on the top plate, 18, to engage with such ratchet,or the reverse-a ratchet on the top plate and a pawl on the hub of the wheel; but we deem both the locking-plate and pin devices as preferable to a ratchet and pawl for locking the wheel of our machine.

Ve sometimes provide a follower, 51, Fig. 23, which is attached to the outer end of the lever by means of an eyebolt up through the lever and a spike driven into the upper end of the wooden follower 51, such spike having an eye at its upper end, and said eye welded into the eye of the aforesaid eyebolt, this connection forming a link-joint. By turning the eyebolt in the lever the follower can be easily set to follow the lever in either direction around the circle, and by its lower end pressing into or against the ground a brace is thus formed to hold the lever and relieve the horse or team, when desired, in operating the machine.

To cause the horse or team to be led properly around the circle while operating the machine, we usually provide a lead-bar, 52, Fig. 23, to which the team or horse is tied. This lead-bar is connected with the lever by means of an eyebolt passing downwardly through the lever and secured by a nut on the under side thereof, and the lead-bar being provided with a slot or opening at its inner end to receive the eye of such eyebolt,and through the leadbar and eye ofthe aforesaid eyebolt we insert a cross-bolt. This connection will enable the operator to cause the lead-bar to project out wardly from either side of the lever to lead the horse or team in the proper direction around the circle. The lead-bar 52 is held in position by cast cups 53 53, with open top to receive it, the cups being bolted to the lever.

As a modification of the horizontal chainguide box of our machine, any part of the same with which the chain comes in moving contact could be replaced by guide pulleys or wheels mounted in a swinging frame surrou nding the chain-wheel.

If we wish to produce a geared machine having greater power and slower movement than the machine described, wemount a large cog'wheel on the shaft of the chain-wheel, and on another shaft back of the chaiirwheel we mount a pinion meshing with the large cogwheel. The draft-lever would be connected with the pinion or its shaft.

The bed-plate and top-plate of the machine would have to be extended back far enough to provide bearings for the extra shaft.

Instead of the large eogwhcel we sometimes mount a large chainwheel on the same shaft and above the chain-wheel that operates the draftchain, and on the rear shaft, instead of the pinion, we mount a smaller chain-wheel, and with a chain-belt running from the small to the large chain-wheel. The operating-lever connected with the small chain-wheel or its shaft would drive the large chaiirwhecl, and also cause the chain wheel below on the same shaft to rotate and operate the draftchain. The upper and lower bearings of the rear shaft could be arranged to move backward or forward in slots cut in the top plate and the bed-plate, so as to conveniently tighten or loosen the chain belt to have it of the proper tension. The operating-lever could be connected with the large chain-wheel if less power and more speed be desired.

The chain-wheels hereinafter mentioned in the claims of this application are to be con strued as meaning those that come in direct contact with the draft-chain and operate said draft-chain, and not to be construed as meaning the belt-chain wheels above described as substitutes for the large cog-wheel and pinion for obtaining the increase of power of the machine.

For pulling stumps that are too low to permit a chain-hitch thereto, or where the tops of thestumps are so much decayed that they would pull off, we use thclow stump-hook, 54,1nade of metal, with a broad point and wit-h notches 55, as shown, and also provided with a ring or clevis, 56. These notches 55 are to prevent the hook from cutting too deeply into the wood and to eauseit tohold more securely to the stump. The clevis or ring 56 is to hitch a light chain into and around the roots or body of a stump when the hook happens to slip off before the stump is entirely out of the ground and to render it unnecessary to make a second hook-hitch. The clevis or ring 56 affords a convenient hold for the hand when using or setting the book.

The side hitch-chain, 57, Fig. 20, could be made with links of round iron or metal; but we usually make some of them of square iron or metal, set eorncrwise, or so that some of the corners are projecting outwardly, to cut into the wood and hold more securely when a slip-noose bitch is made around the stump by means of the chain and its hook 58. The fly-link 59 on the other end of such chain is used to make the connection with the draftchain 30, as shown in Fig. 23.

In pulling stumps that are not within reach of the draftchain and side chains, we sometimes usein connection therewith the hooked bar 60, Fig. 21, or the hooked barGl, Fig. 22, and in some cases we use wire rope, the hooked bars and wire rope being lighter to handle and cheaper than chain of same length and equal strength, and in some places they answer the purpose fully as well.

For obtaining more power than the direct draft affords, we use the pulley-block 62, as shown in Fig.23. This pulley-block,also shown in Fig. 13, consists of a metal pulley or sheave 63, secured within the metal bail or clevis 61-, by means of the metal shaft 65, which passes through the hub of the pulley and also the two eyes of the bail or clevis 64. The shaft is held in position by riveting the ends, or cross-pins could be used through the ends of the shaft just outside of the bail or cleviseyes, such pins projecting a short distance outwardly from the shaft 65. The jack 38,

Figs. 16 and 17, is preferably of wood, and has side pieces, 67 and 67, Fig. 16, mortised into the sill 68.

To hold the side pieces together at the top, we usually'providea metal band, 69, and in some cases a cross-bolt, 70, and another crossbolt, 71, to aid in holding the sides together when inuse and under heavy endwise strain.

The sill 68 of the jack can be made straight: but we prefer to have it bow upwardly, as shown in Fig. 16, thereby diminishing its liability to breakage when in useif a stone or large root happens to lie beneath its middle or weaker portion. If the jack is properly set and connected with the draftchain of the machine, greater power and .an upward lift is also exerted .on the stump,both features being at times'desirable in pulling heavy or large stumps. The jack can be used either with or without the pulley-block 62; but when the pulley-block 62 is used in connection with the jack, as shown inFig. 23, greater power is thereby obtained.

In use, the machine is anchored and the draft-chain 30 is connected with a number of stumps, as shown in Fig. 23, when a horse or team is attached to the draft-lever 15 and the machine operated. After the draft-chain is drawn in upon one side, the other end of the chain is connected with several stumps, and

the horse or team pulls the sweep or draftlever in the opposite direction. The operation is repeated in this manner until all the grnbs and stumps within the range of the ma-. chine are pulled up, when the machine is drawn to a newanchorage.

The machine is not staked down when in use, but left free to swing laterally on the ground from its anchorage into theline of draft of the stump with which the draft-chain is connected.

a In Fig. 17 the jack is shown in proper position for pulling when the chain is connected with the back of the stump; but in some cases we hitch the chain to a front root of thestump, setting the jack a little farther from the stump and at about the same angleas shown in Fig. 17 This front root hitch tends to tip the stump over backward, and if the stump is a large and difficult one 'to pull, and the jack rather short, or if obstructions prevent setting the jack close to the stump and hitching to the back thereof, then the front-root hitch above described should be made.

In making root-hitches we use the clevis 7-2 in preference to a chain with a hook permanently attached to it, because in many cases roots interfere with or render it difficult to get a hole under the root to which the hitch is to be made and such hole large enough to let a hook of the requisite size through the hole, so as to make the slip-noose hitch; but in the other case the clevis is not put on untilafter the chain has been passed through the hole,

" which need not be made so large for the chain as would be necessary if a large hook were permanently connected with it. We also at times use the clevis-hitch around the body of a stump, if a large one.

Aside from stump-pulling, our machine can be used for moving buildings, drawing ditching-machines, and in fact for moving heavy bodies of any kind within its range of power.

For drawing a. ditching plow or machine where the ground is too soft to afford a good ,footing for the horse or team, we provide a platform of sufficient size to enable the horse or team to operate the stumpf-extractor thereon, the extractor being secured to the center of the platform and the ditching machine or plow attached to the anchor-chain and back of the platform, with the draft-chain of the machine orextractor connected at its outer end with an anchor of sufficient strength. The

machine is now operated, and the platform, with the machine and team or horse upon it, and the ditching machine or plow connected, will all be drawn toward the anchor at outer end of the draft or main chain. This platform should be provided with suitable runners, and could be made in sections for greater portability, and when in use the sections properly secured together in any suitable manner.

For convenience in withdrawing or of insert-ing the pins 45-and 48, Fig. 6, we may connect a lever therewith in any common and suitable manner to accomplish the desired purpose; and in some cases we may use a spring in connection with said pins, or one of them, and such spring adapted in any common and suitable manner to insert or withdraw the pin with which it may be connected.

Instead of the fly-link 59, Fig. 23, for connecting the chain 73 with the pulley-block 62, we sometimes employ a strong metal clevis having parallel sides provided with holes to receive the cross-pin for closing the open end of such clevis; and we also at times use such clevises to connect one chain with another to reach out long distances when pulling stumps, but do not use such clevises for connecting a side chain elsewhere than at the end of the main or draft chain 30, because a clevis will not connect a side chain to any link of the main chain 30 as a lily-link is capable of doing.

Instead of the chain 73, Fig. 23, being used over the top of the jack, we sometimes use what we term jack-bars, composed of two bars of metal with two of their ends connected with a short piece of chain. In using thejackbars, we place the chain part thereof on or over the top of the jack and attach or connect one of the bars with the pulley-block and the end of the other bar with the chain thatis connected with the stump. The jack-bars are lighter to handle than a heavy chain.
