EXCAVATING AND SHOVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 477,933, dated June 28,1892.

Application filed February I 1892. erial No. 419,949. (No model.)

To all whom it may concern:

Be it known that I, EDWVARD, HENNEBERY,

of Duluth, in the county of St. Louis and State and use it, referencebeing had to'the accom panying drawings. which form part of this specification.

My invention relates to improvements in excavating and shoveling machines; and it consists in the construction, arrangement, and combination of parts, which will be fully described hereinafter, and particularly pointed out in the claims.

The object of my invention is to provide a shoveling or excavating machine which is adapted to be used for shoveling coal or other material upon a wharf or for excavating purposes and which can be placed upon wheels, if desired, the parts being so constructed and arranged that they can be reversed and all of the parts operated without reversing or stopping the driving-power or engine.

In the drawings, Figure 1 is a side elevation of an apparatus which embodies my invention. Fig. 2 is a plan View of the same. Fig. 3 is an enlarged plan view of the driving mechanism. Fig.4is a detached view of one of the spools, showing the mechanism used to shift the same, and also the brake mechanism. Fig. 5 is an enlarged detached view of the bucket and the mechanism for dumping the same;

a indicates a platform, which is placed upon casters to be moved around or secured to any desired object or upon the ground stationarily, or which can be placed upon wheels to run upon a track, as will be readily understood.

Extending upward and inclined forward to have their front'ends over the front edge of the platform are four uprights b, which have their upper ends connected by means of a cross-block h. Extending outward horizontally from the front of this cross-block h is a block e, which forms a journal or pivotal point for the upper end of a crane, the lower end of the crane being pivoted to a block or extension of the platform, as shown. This crane is composed of a vertical standard 1', comprising two pieces, a horizontal arm j, and the diagonal arm 70. -Each of these-1s composed of two parallel bars, as shown, and the bars forming the diagonal arm or brace havetheir upper ends connected to the horizontal bars j near their outer ends andv to the vertical standards inear their lower ends. Connecting the bars k and the standards'i between their ends are the horizontal braces m, and at the junction of these bars with the standards is an inwardly-extending horizontal circular disk or platform a, which has a groove around its periphery to receive operating chains orropes p. Connecting the standards I) are the horizontal bars q, and-resting upon these bars q are the bars d. Supported at the inner ends of these bars d is a block 0, which, carries two horizontal sheaves or guidingwheels r, between which the'ropes or chains 1) pass. These ropes p then pass over sheaves 8 down to an operating-spool 13, around which they are wound in opposite directions, so that when one ropeis winding up the other is'unwinding for a purpose to be fully set forth hereinafter. Y

Pivot'ed between the standards 1' by means of a short'shaft J, to which their ends are rigidly secured, are two arms H. The outer ends of these arms are pivoted to opposite sides of a bucket-arm I near its outer end. Also rigidly connected to the short shaft J is arm -K, which extends upward, as shown, and owing to the fact that the arms H and K are rigidly secured to the shaft J, which forms a pivotal point for them, they both move together. A rope L is connected to the bail of the bucket and-has one end connected to the outer ends of the arms j, then passes downward around a pulley M, which is connected with the bail, then up around a pulley N, then through between the pulleys in the block h and over a pulley g, and is connected with the spool A. A rope P is connected at one end to the upper and outer end of the arm K, passes down around a pulley Q,-journ'aled in the arms is, then around a pulley R and to a spool D, if it is to be operated by the gearing. On the other hand, if the-rope P is to be operated by hand it will have its lower end connected to a spool S, which is journaled upon the lower ends of standards 2'. In this instance a platform T will be secured to the standards for theoperator to stand upon.

lonnected to the bucket-arm I between its ends is a rope U, which passes under a pulley V, journaled between the arms H, then up over a pulley W, journaled in the upper ends of the standards 1', then down around a pulley X, which is upon the shaft J,between pulleys Y, journaled in the horizontal block Z, and then to and around its operating-spool C.

Journaled in a suitable frame-Work upon the platform a are the operating- shafts 1, 4, 14, and 15, which carry the operating-spools. The shaft l is what maybe termed the driving-shaft, and is connected with a suitable engine through the medium of the wrist-pins or cranks 3. Secured rigidly to the shaft 1 is a. gear-wheel 2, which. meshes with a large gear-wheel 5, that is rigidly secured to the shaft 4. This gear-wheel 5 in turn meshes with the gear-wheel 6, which is rigidly secured to. a shaft 14, and the gear-wheel 6 with a gear-wheel 9, which is rigidly secured to a shaft 15. Rigidly secured to the opposite end of thisshaft 15 is a gear-wheel 11, and loosely placed. upon the same end of the shaft 14 is a gear-wheel 13. Placed between these gearwheels 11 and 13 is an idler 12, by means of. which the wheel13 is given a reverse revolution tothe wheel 6,-as will be understood, as the wheel 13 is loose upon its shaft. I

The spool B is placed loosely upon the shaft 14 and is. provided with clutches '7 and 8, which engage similar clutches upon the inner sides of the wheels 6 and 13. Owing to the fact that the wheels 6 and 13 upon the shaft 14 are revolving in opposite directions in orof the spool B, to which the chains or ropes p are connected, as before described, it is only necessary to slide the spool endwise upon the shaft 14, so that theclutch upon one end will engage the clutch upon the inner side of either the wheel 6 or 13, while the clutch at the other end is disengaged from the clutch of the opposite wheel, as will be readily understood. In this manner the crane is revolved in either direction, as the operator may desire, to bring the bucket at the desired point. The spool B is made sufficiently shorter than the distance between the wheels 6 and 13 to allow it to be stopped with its clutches at each end out of engagement with the clutches of the wheels, so that the crane will be allowed to remain still while the other mechanism is at work.

At one end of the spool A is a friction-disk 18, which engages a friction-disk 19 upon the inner sideof the-gear-wheel 5. The spool A is made loose upon the shaft 4, so that it can be moved endwise by means of a suitable mechanism and made to engage with the frictiondisk of the wheel 5ror be moved in the opposite direction to be disengaged therefrom. In this way the spool A can be made to revolve or stand still, as the case may be. The hoisting-rope L, that is connected with the bucket, is operated by the spool A, so that by moving the spool A endwise the bucket can be raised or allowed to drop down, as may be desired.

As before stated, the spool O is loosely placed upon its shaft, and by this means it 13 given an endwise movement in relation thereto. At one end this spool O is provided with a clutch 10 and the wheel 9 with a similar clutch, which engages therewith. With this spool the rope P, that is connected with the arm K, is connected, and the rope thereby wound up or allowed to be slack by the endwise movement ofthe said spool.

Secured to the opposite end of the spool C from its clutch is a friction-disk 20, which engages and operates in connection with the friction-disk 21 of the spool D for revolving the last-mentioned spool. This spool D is journaled in eccentric boxes, and is thereby moved toward or away from the disk 20, and thereby made to engage for operating it or disengaged for the purpose of allowing its rope to unwind.

Each of. the spools A, B, and G are moved endwise upon their shafts by means of levers 22, which are pivoted between their ends and extend under the platform a. The upper ends of these levers 22 engage with grooves inthe spools, and connected to their lower ends are bell-crank levers 23, which are in a horizontal position. Arod 24 has one end connected with the opposite end of these bell-crank levers, and-the opposite ends of these rods are connected to the lower ends of levers 25. By 1, means of these levers 25 the movements ofall of the spools are under the control of the operator.

der to change the direction of the revolution By means of the above-described construction the movements of the bucket through its arm or lever are entirely under the control of the operator, and this without stopping or reversing the motion of the engine or the source of power.

The bucket or shovel 28 is pivoted-between two arms 29, which extend outwardv from its arm by means of the bail 30, which has its ends bent inward through the arms 29 and the sides of the shovel 28. Pivoted between the upper ends of the bail 30 is a plate 31, which is provided with a perforation to receive a ring 32, to which the hoisting-rope is connected. Also pivoted between the upper ends of this bail is a lever 33, which extends rearward and is pivotally connected between its ends to the upper ends of two bars 34.

,These bars 34 have their opposite and lower ends pivotally connected with the rear end of IIO As the spools A, B, and O are loose upon their shafts, it is necessary to provide for each a friction device or brake, so that they will not allow their ropes or chains to unwind too rapidly when they are out of engagement with their operating-wheels. So, also, the wheel D has a free movement when it is not in engagement with the friction-disk of the spool G, and it is necessary to provide a brake for it also. The brake mechanism for each of these spools consists of a vertical footbar 41, which extends up through the platform within reach of the. operator, and connectedat one end to the lower end of the bar 41 is a horizontal lever 39. This lever 39 is pivoted between its ends to a depending standard 38, and connected tothe opposite end of the lever 39 is a vertical friction bar or brake 40, which extends upward through the platform and engages a friction-disk upon the spool. In this mannerv the unwinding movements of the spools are under the control of the operator, as will be readily understood.

The object of the rope U is to pull the bucket-lever down and in toward the standards 1, while the object of the lever K and the rope attached thereto is to hold the bucket down in contact with the object or material being operated upon by the shovel or bucket, thus causing it to enter the material when it is being raised by the hoisting-rope L.
