EXCAVATING-BUCKET.

SPECIFICATION forming part of Letters Patent No. 747,480, dated December 22, 1903.

' Application filed June 17, 1903. Serial No. 161,893. (No model.)

To all whom it may concern: of mechanisms which are in turn controlled Be it known that I, HENRY L. REYNOLDS, a by the swinging of the hangers. citizen of the United States, and a resident of In the drawings, 1 represents the scoops, Jersey City, Hudson county,New Jersey, have two of which are provided, said scoops pref- 5 invented certain new and useful Improveerably having a bottom and two sides, the

Four of these hangers are in the following specification and its scope employed, two for each scoop, the same being will be defined by the claims terminating the placed one at each side of a scoop. The comsame. v mon pivot 3 for the hangers is preferably a In the'drawings accompanying herewith 1' rod, which extends transversely of the bucket 15 have shown my invention'embodied in'a form' and connects the hangers of one side of the now preferred by me. bucket with the hangers at the other side of In the drawings, Figure 1 is a side elevathe bucket.

In order to se- If the pin 32 is maintained on the central cure this action, the scoops (by which term line of the bucket while the two parts are 45 I mean the lower bucket-like members which separated by the swinging of the hangers, and 5 contain the material) are pivotally carried-by if at the same time this pin be moved-downhangers or levers, which in turn are pivoted wardly upon such center line as-the hangers at or near their upper ends so as to swing swing outwardly, the scoops will during the toward and from eachother. The scoops are major part of their outward movement be 50 controlled in their angular position by means maintained approximately in the same anguloo 'lines in Fig. 1.

larposition as when closed, and during the latter part of the outward swinging movement of the hangers the buckets will be rapidly rocked into the vertical position shown by the broken In order to secure this action, I have connected the pivot 32 by means of links 4, which, in effect, form a toggle with the outer ends of extensions 2 of the hangers beyond their pivot 3. These extensions lie upon the opposite sides of the pivot 32, from the hangers of which they form a partthat is, the extension 2, which lies at the right of the center line of the bucket, isa part of the hanger 2, which lies at the left of the center line of the bucket, and vice versa. I have herein shown these extensions as being substantially horizontalin the closed position of the bucket. The exact angle made by these extensions, as well as by other parts of the device, and also the relative lengths of the parts and locations of the pivots, may be widely varied without changing the essential character of the invention. By varying these parts the action ofthe device may be widely changed.

As the hangers are swung outwardly the extensions 2 swing downwardly, which carries the toggle-links 4 downwardly and at the same time closes the toggle, which tends to carry the central pivot thereof, 32, downwardly at an increased rate. The position of the parts when the bucket is opened is shown by the broken lines, composed of alternate dots and dashes, in Fig. l. The first action of the toggle-links 4 upon the scoops 1 is to depress the outer ends thereof; but this depression is counteracted somewhat by the fact that the links 15 are primarily at aconsiderable angle relative to the direction of the hangers 2. As the hangers near the outer portion of their swing the links 15 pass the horizontal position and farther movement downward draws inward the outer end of the bucket. At the same time the inner ends of the bucket-s continue moving outwardly, which results in a rapid rocking action upon the bucket, which quickly turns it into the vertical position.

The means provided for opening or swinging outwardthe two parts of the buckets consists of toggle-links S, which are pivoted to the hangers at 30 and have a common or center pivot 31. The pivots 30 are removed laterally from the center line of the bucket, so that if the common pivot 31 be moved upwardly the hangers will be swung outward or separated. This central pivot 31 is moved upwardly by means of an opening-rope,which is connected thereto. This opening rope might be connected directly with the pivot 31, but in some cases such a connection would not provide a sufficient opening power. In such event this power may be increased by the means which are clearly shown in Fig. 2. As therein shown, a single opening-rope 16 islocated centrally of the bucket and at its end is branched so as to provide two end sections 6. The lower or central pivot for the toggles is in the form of a transverse shaft 31, which connects the two toggles at opposite sides of the bucket. Upon this shaft are mounted two pulleys 9, which lie substantially in the central transverse plane of the bucket. The two branches 6 of the opening rope each pass about one of the pulleys 9 and then upward. Each of these branches may then be directly connected with the transverse shaft 3, which forms the pivot for the hangers, or, as is herein shown, they may be passed around pulleys 19, carried by said shaft, and thence downwardly and be attached to the shaft 31. Itis obvious that by pulling upon the openingrope 16 the shaft 31 will be powerfully drawn upward or toward the shaft 3, which will open out the toggle-links 8, and thus separate the two parts of the bucket.

The closing means shown consist of pulleys 7, mounted upon the hangers as near to their lower ends as convenient, about which extend the closing-ropes 70, one rope being used at each side of the bucket. The power of these closing-ropes may be increased by increasing the number of pulleys 7. I have herein shown two such pulleys upon each hanger. One end of the closing-rope is socured to one of the hangers by any suitable means and thence passes about the pulleys 7 and thence upward through a guide or over a pulley 17, located adjacent to the pivot of the hangers.

I prefer that the rods 30, by which the opening links or toggles 8 are pivoted to the hangers, be located at such a distance from the pivot 3 of said hangers that the extensions 2 of said hangers may swing within said rods 30. In some cases there may be no necessity for such clearance. The toggle-links 4, which together with the extensions 2 and links 15 constitute what I have called the scoop-controlling or position-controlling devices, are preferably placed outside of the plane of the opening links or toggles 8, so that their centers may freely pass.

I do not wish to be understood as limiting myself to the exact construction or operation of parts herein shown and described, but to claim any construction which falls within the scope of the claims terminating this specification.
