LOADING OR UNLOADING APPARATUS.

SPECIFICATION formingpart or Letters Patent No. 679,967, dated August e, 1901.

Application filed May 11, 1901.

To aZZ whom it may concern.-

Be it known that I, GEORGE H. HULETT, of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Loading or Unloading Apparatus; and I 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 apperxo tains to make and use the same.

My invention relates to an improvement in loading and unloading apparatus, and more particularly to means for use in unloading boats, one object of the invention being to r 5 provide means for the purpose stated which shall be so constructed as to reach ore or coal under the deck and in remote parts of the hold and receive the ore or coal for conveying the same from the boat to cars or other places for discharging the material.

A further object is to so constructa bucket for use with an unloading apparatus that it can be operated first to gather ore or coal from points more or less remote from the 2 5 hatchway through which the supporting and carrying means for the bucket depend and then scooping the ore or coal so gathered.

A further object is to so construct a combined scoop and gatherer that when operating to perform its functions as a scoop it will occupy no more space than would the scoop alone without thegathering device.

A further object is to provide means for the purpose stated which shall be simple in construction, compact, easy to operate, and which shall be elfectual in all respects in the performance of their functions.

With these objects in view the invention consists in certain novel features of con- 40 struction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a view showing, an embodiment of my inven 5tion. Fig. 2 is a view showing the bucket open and the telescopic section of one of the buckets constituting the gatherer. Fig. 3 is a view showing the buckets closed. Fig. 4 is a sectional view of the telescopic bucket. A represents a boat, and B a hollow de- Serial No. 59,757. No model.)

pending leg carried by any suitable apparatus --such, for instance, as is shown and described in Letters Patent granted to me June 26, 1900, and designated by No. 652,313 and said leg carries at its lower end the buckets or scoops 1 2. The leg B is revolu- -bly mounted and operated as shown in my said patent. The bucket or scoop l is hinged to the lower end of the leg, approximately in line with the wall of the latter, while the bucket 2 is pivoted to the outer end of the horizontally-projecting bracket 6, so that the bucket 2 can be projected under the decks, as will be more fully hereinafter explained. Both buckets or scoops are pivotally connected by links 7 with the lower end of the piston-rod 8 of a hydraulic or other motor 9, so that when said piston is raised the buckets will be moved to a closed position and that by dropping the piston-rod the buckets will be opened.

The bucket 1' is preferably made angular .in cross-section, open at its top 10 and one side 11, thelatter alining with the corresponding open side 12 of the bucket 2 when the buckets are closed to form, in effect, one bucket. The bucket 2, which, as before stated, is a combined bucket and scraper or gatherer, comprises the main body portion or shell 13, open at its sides 12, 14, and 15, and a telescopic member or shell 16, which forms the scraper or gatherer. A hydraulic or other cylinder 17 is located within the body portion 13 of the bucket 2, alongside the inner wall 18 thereof. A piston is located in this cylinder, and the rod 19, projecting from this piston, extends to the far end of the shell or member 16, where it is secured thereto, the cylinder 17, with its piston and piston-rod, constitoting a motor (which can be controlled by 0 any suitable valve mechanism and receive motive power from any convenient source) for moving the telescopic shell or member outwardly and inwardly for scraping or gathering ore or coal from points dist-ant from the hatchway through which the depending leg projects. \Vhen the shell or member 16 is disposed within the body portion 13, the wall 21 of the gatherer will constitute one wall of the bucket, and this wall will form the bottom of mo plate 23, secured to the shell or member 16,

and disposed in a parallel plane with the guard 22, so as to move under it when the shell or member 16 is drawn within the body portion 13. When the shell or member 16 is projected and operated to scrape or gather the ore or coal, more or less lateral strain will fall upon the connection of said shell With th6 main shell or body portion of the bucket. In order to withstand this strain and at the same time permit the free movements of the telescopic shell or gatherer 16, the devices now to be described may be employed. Antifriction-rollers 24: are mounted on short shafts 25, located at the end 15 of the body-shell l3 and run against shoulders 26 on the innershell or gatherer 16, said shoulders being formed by depressing the'corners of said shell or gatherer. A bar 27 is secured to the inner face of each side wall of the body-shell 13, and these bars constitute trackways for antifriction-rollers 28, carried by the telescopic shell or gatherer 16, said rollers being located between the bars or trackways 27 and the rollers 24. The free edges of the side Walls of the telescopic shell or gatherer slide freely in guideways 29, formed by the ends 30 of the telescopic shell 16 and a plate 31, parallel therewith, the parts 30 31 being spaced apart by a bar 32 and secured together by means of bolts v A stilfening-plate 84: is secured within the ends 30 of the shell 16 and secured in place by the bolts 33.

From the construction and arrangement of parts above described it will be seen that the .telescopic' shell or gatherer can be readilyv moved by thehydraulic motor to gather the ore or coal out of reachof buckets as heretofore constructed and that binding effect of lateral strain will be obviated. By rotating the depending leg the-buckets carried thereby can be made to project in any direction and the telescopic gatherer canbe projected far under the decks and operated to drawthe ore and coal in position where it can be readily scooped by the buckets. By my im-- without departing from the spirit thereof or limiting its scope, and hence I do not wish to confine myself to the exact details of construction herein set forth.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In. an unloading apparatus, a bucket comprising telescopic shells, and means for moving one of said shells relatively to the other.

2. In an unloading apparatus, the combination of two shells comprising a combined bucket and gatherer, and means for moving one of said shells relatively to the other.

3. In an unloading apparatus, the combi-- nation witha shellhaving three open sides, of a shell having two open sides and constructed to telescope within the first-mentioned shell, one Wall of the telescopic shell constituting a scraper when moved relatively to the firstmentioned shell, and also constituting a bottom for said first-mentioned shell when the telescopic-shell is disposed therein.

"4. In an unloading apparatus, the combination with a revoluble leg, of a combined bucket and scraper or gatherer carried thereby and comprising telescopic shells and means for moving one of said shells relatively to the other. i

5. In an unloading apparatus, the combination with a support, of two-buckets hinged thereto, one bucket comprising telescopic members, means for moving one of said members relatively to the other and means for closing said buckets together to form a scoop.

6. In an unloading apparatus, the combi nation of two shells comprising a combined bucket and gatherer, and a motor secured within one shell and connected with the other shell.

bucket and gatherer, and guideways for the respectivesides of one shell within the other. In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
