ROBERT J. ASPIN AND JOHN A. ERICKSON, OF LORAIN, OHIO.

BUCKET.

SPECIFICATION forming part of Letters Patent N 0. 759,224, dated May 10, 1904. Application filed July 8, 1903. Serial No. 164,712. (No model.)

To all whom "it may concern.-

Be it known that we, ROBERT J. AsrIN'and J oHNA. ERICKSON, residents of Lorain, in the county of Lorain and State of Ohio, have invented. certain new and useful Improvements in Buckets; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in buckets, and more particularly to that class of buckets known as clam-shell buckets and used for the purpose of loading and unloading coal, ore, grain, &c. and also for dredging purposes, the object of the invention being to provide improvements of this character with improved mounting for the trays or scoops of the bucket to control their opening and closing movements.

l/Vith this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view showing the bucket closed. Fig. 2 is a similar view showing the bucket open.

1 represents the housing-plates of an open frame having a pivotal support 2 for tongs or arms 3, the lower ends thereof being pivotally connected to the inner ends of the scoops or trays 4: of the bucket. Below the pivotal support 2 another pivotal support 5 is provided for the ends of arms or bars 6, the lower ends thereof being pivotally connected with the outer ends of scoops or trays 4.

A great many dilferent operating mechanisms may be employed for our improved bucket, the below-described mechanism being but one means therefor, and to which we do not restrict ourselves.

7 designates the two closing lines or cables. Each closing line or cable is connected at one end to a transverse bridle or hoist-bar 9, to the center of which is swiveled a block 10, from which a cable (not shown) runs to the drum of the hoisting engine or motor. From the bridle 9 the closing-line at each side is carried centrally through the housing at each side down past a guide pulley or sheave 11, thence under a sheave 12 at the central bottom portion of the housing, thence outward and downward around a sheave 13 on the lower portion of one of the tongs or arms 3, thence horizontally across and around a sheave 14 on the other tong 3 at the same side of the bucket, and thence upward at back to the bottom of the housing, where its end is made fast at 15. It will be readily seen, the bucket being open, as shown in Fig. 2, when power is first applied to the closing lines or cables there is a strong downward pull on the four tongs 3, which gives the bucket sections or trays 4 a downward and curving movement from a vertical to a horizontal position to scoop into the material and secure the required shoveling or digging action to load them, while a further movement of the tongs or arms 3 will give to the bucket sections or trays 4 a horizontal movement to bring them together and inelose the material therein.

8 represents the opening lines or cables of the bucket, which are connected at one end to a transverse bridle 1.6 above the bridle 9, to

which bridle 16 is attached a line (not shown) running to a second drum of the engine-motor. From this bridle 16 the line is carried down and under a sheave l t at the central upper portion of the housing, thence outward and over a sheave 17 at one of the upper corners of the housing, thence down and around a sheave 18 on the central portion of one of the tongs 3, thence back up and over a sheave 19, placed side by side with the sheave l7, thence horizontally across and over a sheave 20 at the opposite corner of the same housing, thence down and around a sheave 21 on the other tong 3 at the same side of the bucket, and thence up, where its end is made fast to the axle of sheave 20.

By the arrangement of the tongs 3, pivoted to the forward ends of scoops or trays 4, and the pivoted arms 6, pivoted to the outer ends of the scoops or trays, when the tongs are moved in opening, as above explained, the scoops or trays will pivot on arms 6 and the latter will swing on their pivot 5 to bring the scoops or trays to practically a vertical position as the arms 6 and tongs 3 swing in diliercut arcs, and by disposing the pivotal points 2 and 5 nearer to each other or farther apart and by varying the length of tongs 3 and arms 6 any desired movement can be given the bucketsections.

Slight changes might be made in the general form and arrangement of the parts described without departing from our invention, and hence we do not restrict ourselves to the precise details set forth, but consider ourselves at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of our invention.

Having fully described our invention, what We claim as new, and desire to secure by Letters Patent, is

1. In a bucket of the character described, the combination with a rigid frame, of tongs pivoted to said rigid frame, arms or bars pivoted at their inner ends to the rigid frame, and scoops or trays pivotally secured at their inner ends to the tongs and at their outer ends to the arms or bars.

2. In a bucket, the combination with a frame, of tongs pivoted together and to the frame, arms or bars pivoted together and to the frame below the pivotal connection of the tongs, and

ner ends to the tongs and at their outer ends to the arms or bars, and means for moving the tongs to move the scoops or trays apart or bring them together, substantially as set forth.

at. In a bucket, the combination with a rigid frame and two bucket sections or scoops, of tongs pivotally connecting the inner ends of the scoops with the rigid frame, and arms or bars pivotally connecting the outer ends of the scoops with the rigid frame.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
