WRECKING-MACHINE OR STUMP-EXTRACTQR.

SPECIFICATION forming part of Letters Patent No. 468,644, dated February 9, 1892. Application filed August 14, 1891. Serial No. 402,671. (No model.)

To all whom it may concern.-

Be it known that I, JOHN CoRNELrUs,of Oakland, in the county of Garrett and State of Maryland, have invented a new and useful Improvement in a \Vrecking-Machine or Stump- Extractor, of which the following is a specification.

My invention is an improved wrecking-machine or stunippuller, and has for an object, among others, to provide a simple construction of combined machine which will possess thenecessary strength, be easily convertible to either an elevated wrecking-machine or a flat pulling-machine, and may be conveniently arranged for extraordinary power or for a medium power and a somewhat faster speed or for a less degree of power and a high rate of speed, so that the machine can be advantageously used for light work where a fast movement is desired, for somewhat heavier work with a slower speed, or for the heaviest work, as occasion may require.

The invention consists in certain features of construction and novel combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a side view, Fig. 2 an end view, and Fig. 3 a top plan view, of the machine arranged for wrecking and geared up for the heaviest work. Fig. A is a top plan view of the machine geared for light work. Fig. 5 shows the sweep in detail. Fig. 6 is a detail View of a part of the bedplate, and Fig. 7 is a detail view illustrating the application of the runners directly to the base-frame.

In carrying out my invention I employ a framing including a base or bed A, having at its four corners socket-like parts 13 for the upper ends of the uprights or legs 0, which uprights are pivoted by bolts D in said sockets, so that they can be adjusted to spread the machine in order to raise or lower the bed-plate A to the desired height. The end uprights are joined together by means of connectingbars E, having a plurality of bolt-holes e at one end, so that their connection with one of the uprights may be set to permit the adjustment of the legs by spreading or drawing together, as before indicated. Thus it will be seen the bed-plate may be set to and held at any height within the limits of the machine, or may be lowered to rest flat on the ground or the skids, presently referred to, when a low machine is desired. It will also be understood that, where 5 5 desired, the bed-frame maybe bolted or otherwise secured on a truck or similar carriage to facilitate the loading of safes and similar weighty objects thereon. At their lower ends the legs or uprights O fit in sockets F on the skids or runners G and are secured therein by pinsf. It is manifest that by hitching a horse or team to the said runners the machine can be easily moved from place to place.

Where desired-as, for instance, when the pulling or lifting is extra heavy-the bedplate may be braced and further supported by intermediate uprights orlegs H, fitted at their upper ends in sockets h on the bed-plate and at their lower ends in sockets h on the skids.

In adjusting the machine for use as a low or flat puller these intermediate sockets 71. may be removed from the runners and the bed he fitted down on the said runners between the sockets F and bolted to the runners, as shown in Fig. 7, to which end I provide the bed-plate with lugs I I, perforated for the fastening-bolts, as shown.

In practice the bed-plate is preferably cast of steel or other suitable metal, with the several socket-pieces and lugs integral, and I form the said bed with the top plate at, having the opening a, through which the cable and chain can hang, and with the edge flange-like portion A, which is preferably beveled outward on itsinner surface and extends entirely around the edge of the top plate.

The pulling mechanism upon the top plate includes the main wheel J, which is composed of the worm-wheel made in the two side sections K K, the chain-wheel L, between the said sections, and the drums M, arranged outside the worm-Wheel sections and receiving the cables on, which may be connected at their lower ends with suitable grabs X for engaging the work to be lifted. The chain N, working in chain-wheel L, may also hang down and connect with the grabs, so that the chain and cable may be used jointly or either the chain or cables may be used alone; also, in the use of the machine on the ground the cables may lead off and connect with the work and the chain may lead from the work in through the inlet-guide N, around the chain-wheel, and out through the stripperguide 0, and in such use of the machine either the cables or chain, or both, can be used; but for heavy work I prefer, in all instances, to use both the cables'and the chains.

The main wheel is journaled in bearings in the side frames P, which are cast on the bed and have removable caps p. To turn the main wheel I provide the worm Q, formed to mesh with the worm-Wheel sections and journaled in a frame R, which has upperand lower plates 0" and a connecting-plate r, the latter having lugs for the bolt or rod S, by which the frame It is pivoted at one end. By thus pivoting the frame R at one end it may be adjusted to throw the worm into or out of mesh with the worm-wheel sections and the said parts may be secured in mesh by the locking-rod T. The upper and lower plates 0" are provided at r with bearings for the gearshaft U, which shaft, like the shaft of the worm, is extended upward and the upper ends of both shafts are adapted to receive the-large and small gear-wheels V and '0, and such wheels V and i) may be used in any desired relation, the small wheel 12 being placed on the worm-shaft and the large wheel V on the gear-shaftU for small power and high speed, or Vice versa, for medium power and a slower speed. For extra heavy work, however, I

prefer to use a Worm-wheel WV on the upper end of'the shaftof worm Q and to provide a drive-worm X for meshing said worm-wheel.

The shaft of worm X journals in bearings in the frame Yand extends at both ends beyond the said bearings, being adapted at said ends to receive the hand-cranks Z and the chainwheel'l, the chain 2 being passed over the said wheel 1 and down in convenient reach from the ground. By this chain the operator can from the ground turn the horizontal driveworm and through the connections described turn the main wheel without going up on the machine. This will be found useful in light work; but for heavy work I intend to place a man at the cranks on both ends of the driveshaft, step-boards 3 being supported on arms 4 on the legs 0, such boards 3 being arranged to form a secure footing for the men at the cranks. By means of this drive-worm and the other construction described I am able to get power sufficient for the heaviest work.

'llhedrive-worm is keyed on its shaft by a cross pin or pins 6, and on the shaft between the said worm and the hearings in the frame Y, I place washers 7 loose on the shaft, so that by removing the pin 6 the shaft and its worm may be removed.

It will be seen from the foregoing description that the several changes to adapt the machine for extra heavy work, for medium work with aslowspeed, and for lightwork with afast speed may be easily and quickly made. It will also be seen that by the arrangement of the upright or main worm and the gear-shaft in the movable or pivoted frame the main worm may be quickly set into and out of gear with the worm-wheel sections. To move the said frame from the ground,I provide alever 8, pivoted at 9, so that it can rock on said pivot and also be swung slightly in a direction at a right angles to said rocking motion. Thelower end of this lever extends in convenient reach from the ground, while its upper end connects by a link 10 with the swinging end of the frame R, so that the lever can be operated to throw such frame in or out. When the frame R is thrown in, thelever is engaged and locked by a hook 11, which serves also to lock the poses where a strong pull or lift is required, 7

and it will be readily seen that, While the machine is capable of the heaviest work, it may be quickly adjusted by means of the interchangeable parts to permit it to be used with advantage on the lightest work where speed is desired.

My machine is especially desirable in wrecking, and in such use, when it is desired to remove a wrecked car or cars from the track, the machine may be anchored and'its cable be passed through a block connected with such car and then run off to one side and be provided at its end with an anchor-hook similar to the half of an ordinary marine, anchor, such hook being driven into the ground, when the machine may be operated to quickly pull the car to any desired position.

In order that the machine may be operated by a horse in both its elevated and lowered positions, I provide a sweep-support 13 of a special construction, having at one end a socket to fit on the shaft of either the main worm-wheel or of the gear-shaft and having its portion 14 next the said socket formed to provide a horizontal seat for the sweep-bar 15 when the machine is down on the ground, and having at the end opposite such socket a downwardly-inclined portion 16 to form a seat for the sweep-bar 15 when the machine is elevated on its legs, such inclination of the seat 16 serving to throw the outer end of the sweep down sufficiently low for a horse to be hitched thereto, the change of the sweep from a high to a low machine requiring only the removal and replacing of a few bolts.
