PATENT {)F'FECE.
WILLIAM E. HALE, OF FORT WASHINGTON, PENNSYLVANIA, ASSIGNOR TO B. H. BEAUMONT COMPANY, OF PHILADELPHIA, PENNSYLVANIA,A CORPORATION OF PENNSYLVANIA.
Application filed March 5, 1923.
T 0 all whom it may concern:
Be it known that I, VVUJJAM Eyl-Liiin, a citizen of the United States, residing at Fort lVashiiigton, in the county of l\lontgon'ie y and State of Pennsylvania, have invented a new and useful Improvement in Double- Dunip Skip Hoists, of which the following is a specification.
The principal object of the present invention is to provide for. dumping at different levels or in either of two directions, thereby broadening the field of application and increasing the usefulness of skip hoists.
To this and other ends hereinafter set forth the invention comprises the improvements to be presently described and finally claimed, and in the description reference will be made to the accompanying drawings, forming part hereof, and in which- Figure 1 is an elevational view partly in section illustrative of features of the invention. H.
Fig. 2 is a side view drawn to an enlarged scale and illustrating the construction at one of the discharge points.
' Fig. 3 is a view similar to Fig. 2 illustrating the parts in another position.
Fig. 4 is an elevational View of the bail and bucket, and
Fig. 5 is a top or plan view. I
In the drawings 1 generally is the tower, 2 the pit and 3 the loader. 5 is the bucket and 4 is the bail to which it is pivoted in the usual or in any well understood manner, and 6 is the hoist. The tower guides 7 for the four wheels 8 of the bail extend continuously and uninterruptedly throughout the length of the tower, so that the bail is guided by the guide 7 in its predetermined path of travel. The guide rails for the bucket are arranged'in pairs 9 and 10 and the wheels 11 and 12 of the bucket are also arranged in pairs. There are discharge points at 'difierent levels and their number may be increased or diminished and some of them are right handed and some left handed. In the drawings it happens that four discharge points a, b, c and d, are shown and of these a and 0 happen to be right handed and b and all happen to be left handed. The construction at each of the discharge points is the same, except that Serial No. 622,836.
tion and operation at one of the discharge points will be sufficient. At each discharge point all of the guides 9 and 10 for the skip bucket are interrupted and their ends are spaced apart, but the guides 7 for the bail are not interrupted and are continuous. At the discharge point and where the bucket guides are interrupted one pair of the bucket guides 10 is provided beneath the interruption with a curved eXtension13 and the other pair of guides 9 is provided with a switch 14, movably mounted, as shown by pivotally supporting it at 15. Thereis a switch, of course, for each of the guides of the pair 9 but a description of one of the switches will suflice, since they are duplicates of each other. The switch is provided with a straight groove 16 and with a point 17. When the switch 14 is in the position shown in Fig. 3, the bucket wheels 12 run through its groove 16 and the side walls of the groove afford the lateral supp'ortbr guidance nec essary to prevent the bucket from tipping in respect to the bail, so that the bucket and hail run past the discharge point. It might be said that the walls of the groove 16, acting upon one pair of bucket wheels, perform the function that is usually performed by both pairs of guide rails. hen the switch 1 1 is in the position shown in Fig. 2 the point 17 operating on the guide wheels 12 ensures that the bucket will tip in respect to its bail in the proper direction for dis charging either to the right or to the left but in Fig. 2 toward the right. The structure at the discharge point is adapted to make what might be called a split switch in that the bail continues to travel in the same direction whilst the direction of the motion of the bucket is changed, either to the right or left, and this may occur at different levels, according as the switches are set. For the sake of clearness certain usual provisions, such as counterweights for the buckets and provisions for stopping, starting and reversing the hoisting gear have been omitted, but they are too well understood by thoseskilled in the art to require illustration or description.
In use by properly setting the switches it is possible to dump at any discharge point,
i. 0., at different levels, and in the design of the structure it is possible to dump either right or left-handed as may be required.
It will be obvious to those skilled in the art to which the invention relates that modifications may be made in mere matters of form without departing from the spirit of the invention which is not limited as to those matters or otherwise than as to prior art and the appended claims may require.
I claim:
1. A skip hoist adapted to dump at different levels and in different directions and comprising the combination of a tower, a
bail guide, an interrupted bucket guide,
dumping extensions at different sides of the interruptions and at different levels, and switches arranged at the interruptions and disposed opposite the adjacent extensions.
2. In a skip hoist the combination of a bail and bucket pivotally connected, a dumping extension, a bail guide extending continuously past the dumping extension, a bucket guide provided with an interruption above the extension and with a switch at the interruption for turning the bucket in respect to the bail and" for holding it in normal position in respect to the bail.
A double dump skip hoist comprising in combination a tower, a bucket and bail pivoted together, means for hoisting the bucket and bail up and down the tower, a bucket guide provided with lateral dumping extensions arranged at interruptions provided in the bucket guide and disposed at different levels, and switches arranged laterally at the interruption and each having three surfaces for co-operation with the bucket and of which one turns the bucket -in respect to the bail and dumping extenguide continuous through said space, a discharge extension at one side of the bail guide below said space, and a switch at the other side of the bail guide and in said space.
A double dump skip hoist comprising a bucket, a tower having discharge points, two-way bail guides extending continuously and uninterruptedly throughout the height of the tower, two-way bucket guides disposed at opposite sides or the bail guides and interrupted and spaced apart at the discharge points, a curved extension provided beneath the space at the interruptions and on one of the bucket guides, and a switch interposed in the other bucket guide at the interruption and adapted to bridge the space and itself provide a two-way bucket guide and to deflect a bucket through the space provided at the other bucket guide.
WILLIAM E. HALE.
