Specification of Letters Patent.

Patented March 5, 1907.

Application filed December 22, 1905. Serial No. 292,912.

To all Lu/tom it 77mg concern:

Be it known that I, JOHN F. DOEHLE, a subject of the Emperor of Germany, and a resident of the city of Plainfield, in the county of Union and State .of New Jersey, United States of America, have invented certain new and useful Improvements in Conveyers, of which the following is a specification.

My invention relates to bucket conveyors and its object is to provide a simple and cheap construction for conveyors of this type which will have many advantages over those now in use.

I will now describe my invention in the following specification and point out the novel features thereof in claims.

Referring to the drawing, Figure I is a vertical section through the line 1 2 of Fig. II of a part of my conveyer. Fig. II is a side elevation of a part of my improved conveyer, showing the manner in which the various parts are connected together and also a de vice for loading the conveyer. Fig. III is a side elevation, on a smaller scale, of a part of one of my improved conveyors, showing one form of driving mechanism and also showing its track with vertical curves. Fig. IV is a plan view of similar parts, showing the conveyers with horizontal curves. Figs. V and VI are respectively end and side elevations of an arrangement which I use for automatically dumping the buckets of the conveyer.

Like characters of reference designate corresponding parts in all of the figures.

A designates a rigid track or traction-rail. It is here shown as an ordinary channel-iron, as this is a preferred construction. B B designate rods which suspend this rail from any desired structure. These rods B B may be run through the channel-iron and have cross-pieces C placed through them upon which the channel is supported. The other end of these rods may be attached to a rope or cable 11, which may be supported upon poles 10, or they may be attached to a rafter 12 of a building, if desired. A plurality of trolleys are arranged to run upon this traction-rail A. In Fig. I it may be seen that these trolleys comprise two flanged wheels I) D, which are supported upon suitable brackets E E, which extend from the wheels D downward on either side of the rail A and are joined together by bolts or screws, as shown at F.

A haulage-cable G is arranged to connect a strap leys, and this cable may be rigidly connected to the brackets E E where the brackets are connected together at F. This haulagecable may be made of any desired materialsuch, for example, as chain or ropeand the various trolleys may be attached to it at equal distances from each other. One of the bracketsE is extended downward, as shown at E, and a hinge-piece J may be attached to it by means of a bolt H. Another bolt- H may be inserted in this hinge-piece at right angles toI the bolt H and arranged to support L L designate buckets. Upon each side of these buckets are loops M M, which are connected to the straps N N by links K K. It may be seen then that the buckets are supported upon the trolleys by means of these links K K and that between the links and the lower ends E of the trolley-brackets is a universal oint formed by the hinge-piece J and the two bolts H and H, which pass through it. These parts are preferably so arranged that the buckets L L are held apart from each other a certain amount, so that they may not interfere with each other when they are driven about curves in a manner which will be pointed out later. This construction leaves a space between the buckets, and it is desirable to have this space properly covered in order that no material may fall between the buckets when it is running through a chute into the buckets, as will be fully pointed out later. For this purpose I provide plates 0, which may be connected, as shown in Figs. I and V, to the hinge-piece J by means of links I. These plates are arranged to rest upon the upper part of buckets L, and in order to support them and keep themfrom dropping in between the buckets when they run around a curve brackets P P, formed of angle-irons, may be attached to the side of the buckets and arranged to support the plates. The upper portion 0 of these plates may be extended over the hinge-piece J and may rest upon the same.

X designates a chute through which material may be passed into the buckets L L. It is often desirable to fill these buckets while they are moving, and in order that this may be done simply it is desirable to pass material through the chuteX continuously. The lower opening of the chute is placed directly above the mouths of the buckets, so'that the material passes into the buckets which are directly the various brackets or hangers of the trol- 1 below the chute. As the buckets pass the lower end of the chute, however, the material will be caught upon the plate 0, which covers the space between adjoining buckets, and some of the material will therefore rest upon the plate 0. The chute is, however, preferably provided with a vertical plate X, which is situated directly above these plates and is arranged to scrape off such material as has accumulated on the plate into the next bucket. The chute may of course be placed in any desirable position along the line of travel of the conveyer. The center of gravity of the buckets is preferably on the opposite side from that into which-the material passes, so that they will normally maintain an upright position. Any tendency of the weight of material in the buckets to tilt the buckets so that their mouths would be raised above a horizontal position may be stopped by the flanged portions 0 of the plates O, which rest upon the hinge-piece J and prevent a farther upward movement of the mouths of the buckets. This flanged portion 0 also serves the purpose of protecting the hinged oints by which the buckets are supported to the trolleys. A projecting roller Q may, however, be provided upon each bucket, and guide-rails, such as R, (shown in Fig. I,) may be provided opposite the chute X for the purpose of steadying the buckets while they are being filled and preventing the material which falls into the buckets from tipping them over. Wherever it is desired to discharge the material, another guide-rail S may be provided, which will engage with the projecting rollers Q and act as a cam to raise the under portion of the buckets, as is shown in Figs. V and VI, and to again bring them back to their normal position. This cam-rail S may of course be situated at any desired point along the path of travel of the conveyer. When the buckets are tilted in the manner just described, the plates 0, which are attached to the hinge-piece J by links I, will also be tilted sufficiently to allow any material which has not been scraped off from them to slide off. This is clearly shown in Fig. V.

Referring now to Fig. III, it may be seen that the track A is constructed with two vertical curves. With my construction it is perfectly feasible for the conveyer-buckets to e run over such curves. Of course in doing so the distance between the buckets will be increased or decreased; but by the arrangemom of hanging them which I have invented this does not interfere with their operation in any way. When the trolleys are run over an upward curve in the track, it is desirable to place a guard-rail W over them in order to prevent the tension on the haulage-cable G from lifting them from the track A. T designates a driving-wheel for the haulage-cable G, which may be rotated by any suitable motive power. This wheel '1 may be provided with recesses T, as shown in Fig. IV, which are provided for the purpose of allowing the hanging brackets E to pass this wheel with out interference.

In Fig. IV the buckets are shown passing around horizontal curves, and in this case the wheels U and V V are preferably provided for the purpose of guiding the haulage-cable. These wheels may be provided with recesses U and V for allowing the hanger-brackets E to pass the wheels without interference. Of course these wheels may be provided with means for adjusting their position in order to keep the haulage-cable G at proper tension in any of the well known manners.

This bucket-conveyer system which I have invented may be very cheaply constructed, and because of the fact that the track which carries the bucket is suspended by rods it may be readily set up either in a building or in a field, for the rods B may be simply attached to a rope or caple 11 and this cable supported in any simple manner.

The construction work for the track may be made with very little weight compared with the amount of work which the conveyer is capable of doing. It is also a very simple conveyer to maintain and keep in order, as all of its parts are accessible for lubrication and for repairs.

The construction which I have specifically described is merely to illustrate the use of my invention, which, of course, may be con structed in many different waysfor example, the universal joint may be dispensed with, or the buckets may be suspended by means of chains instead of links.
