LOADING OR UNLOADING APPARATUS.

- SPECIFICATION forming part of Letters Patent No. 601,670, dated April 5, 1898.

Application filed January 30, 1897. Serial No. 621.302. (No model.)

To all whom, it may concern:

Be it known that we, JOHN MOMYLER and GEORGE H. HULETT, residents of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and 'useful Improvements in Loading or Unloading Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in loading and unloading apparatus.

The object is to provide means for reaching under the decks of vessels and unloading rapfor the support of the mechanism, aleg supported thereby and depending therefrom, and a scoop or bucket connected with the lower end of the leg and capable of being turned completely around relative to its support.

The invention further consists in certain novel features of construction and combina tions of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of our improved loading and unloading apparatus. Fig. 2 is a view in end elevation, and Figs. 3 and tare enlarged detail views showing means for revolving the bucket or scoop.

A represents the frame on which our improved apparatus is supported. This frame may be stationary or portable, as desired, and in the latter event it is mounted on wheels which travel on suitable tracks.

Bis a beam supported in the present instance between rollers 1 1 on the frame, whereby it may be shifted endwise to convey the scoop or bucket and its load from the boat to the cars, or the reverse if the order of things should be changed, or to regulate its position in the hold of the vessel. This beam may be shifted by means of a hydraulic ram or any other convenient mechanism for accomplishing the purpose. The ram found most serviceable for accomplishing the work is provided with a piston-rod 2, which extends out at both ends of the cylinder. A cable is connected with each end of this piston-rod. One cable, represented by numeral 3, extends in one direction to and around a sheave 4 and thence in the opposite direction to the end of the beam B, where it is secured at point 5. The other cable 6 extends from the opposite end of the piston-rod over a sheave 7 and finally to a point 8 on the end of the beam B, opposite point 5. The operator may be stationed at some convenient station on the beam B and by a proper manipulation of his valves control the movements of the beam on its supporting-frame A. I

A lifting-arm 9 is pivoted at one end 10 to the beam B, and as a means of raising this arm a ram D is provided, its own weight being sufficient to lower it. This ram is pivoted at point 12 to the beam and its piston- 1 rod is pivotally connected at 13 to the liftingarm. While the ram 0 is devised to control the movements of the beam B back and forth in the frame A to move it out over the boat, the ram D is operated to regulate the vertical position of the arm to lower the scoop or bucket to the proper-position to hoist out the load. Pivotally connected with the outer end of this lifting-arm is the depending leg 15. This naturally assumesa vertical position by virtue of its own weight; but as the distribution of the weight is such that it tends to swing the leg obliquely some means, such as a hydraulic ram E, is provided for righting it. This ram is very similar to the ram -D and hence requires but brief mention. The cylinder of the ram is pivoted to the arm 9 and its piston-rod to the depending leg, and by controlling this ram the position of the leg may be perfectly regulated. A foot 17 has a rotary connection with the lower end of the leg, preferably by means of beveled rollers 18 18, which travel around on the annular track 19 on the leg. This foot is provided at its upper end with a pair of drums 2O 20. To each of these drums a cable 21 is secured, and from their points of attachment the cables are wound in opposite directions upon their respective drums and then rove over sheaves and stopped and held at any point in the circle. The scoop or bucket is connected with this foot. This scoop or bucket comprises 7 I two half-shells 25.

foot 17, and they are operated and controlled by means of a hydraulic jack or equivalent mechanism G, pivoted to the foot. These half-shells are similar in form and substantially the shape of a quarter-segment of a circle in longitudinal section. An arm 27 extends upwardly from one half-shell and is connected with the piston-rod of the rain, and a connecting-rod 28 connects this arm with the other half-shell. The bucket or scoop thus formed is opened by the outward thrust of the piston of the ram, whereupon it assumes the position indicated in Fig. 1. The opposite movement of the piston-rod closes these half-shells by forcing them together. Thus it will be observed that the scoop or shovel is self-contained, or, in other words, the entire mechanism for supporting and operating it is carried upon and controlled by apparatus on the foot, so that its operation when in motion is independent of the movement of the support and every part of the machinery for operating it is carried by and is a part of the foot. are, with the exception of ram G, operated and controlled by the operator stationed on beam'B and the scoop or bucket by an operator stationed at the lower end of the leg or in the foot, valves being provided to control the passage of the water, and the water itself is -supplied through hose or metal pipes equipped with necessary universal joints. In this connection it might also be stated that other means, such as steam or electricity, could be employed as well as water for controlling the various parts of the apparatus that is to say, to shift the leg along its support and raise and lower it and rotate the bucket or scoop.

Other slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of our invention, and hence we do not wish tolimit ourselves to the exact conp the beam which carries it.
