DUMPING-SKIP.

` Application filed December 2l, 19O| Serial No. 40,610. (No model.) I

represents a side elevation of the dumping-y skip and the means for operating same on the line 1 1 of Fig. 2, the skip being shown in its upturned position by dotted lines. Fig. 2 represents a front elevation of the skip and a portion of the skip-roads on an enlarged scale. Fig. 3 represents a plan View of the skip.

The skip ais pivoted to the bails b by means of lugs or ears c, preferably formed integral 'with a strap or reinforcingrbar d, secured to the bottom of the skip. The bails are connected with suitable hoisting mechanism c, of any well-known construction, whereby the skip is raised or lowered on the skip roads or guides f. Each bail is provided near its top and bottom with shoes g, that are of sufiicient length to ride over recesses h, provided in the skip-guides. Said recesses are formed in the guides at a point almost opposite the lower ends of curved dump-tracks c', (only one of which is shown in the drawings,) that are secured to and supported upon a suitable framework j, located at the place where the skip is to bedumped. Oorrespondingly-curved tracks 7c vare arranged beneath the dumptracks and preferably extend some distance beyond the upper and outer end of same.

The skip is provided on each side, near its top, with a roller l, journaled upon a stud m, secured to the skip, so that said rollers will engage with the dump-tracks and between same and tracks k when the skip is hoisted. A shoe n is also secured to each side of the skip that is adapted to engage one of the guides, and said shoes are so secured on the skip that they will be opposite the recesses provided in the guides when the skip-rollers engage the dumpingtracks. These shoes are smaller than the recesses that they may readily pass through same and permit the skip to be dumped. Links o, provided with longitudinal slots p, are pivoted to the skip, one on each side thereof, below its center of gravity. The links may be of any desired length, and the slots therein engage the studs or projections q, secured to or formed inte gral with the bails, and are held against disengagement from the studs by any suitable means, as nuts r. gage loosely wit-h the studs in order that the link may ride easily thereon.

The skip is raised in the usual manner by means of a rope secured to the hoisting mechanism and is held to the guides by the shoes that are provided upon the bails and upon its sides. When the rollers that are journaled upon the skip engage with the dumping-tracks, the skip is tilted upon thebails, and simultaneously the shoes secured to the sides of the skip free themselves from the Preferably the slots en-Y guides by means of the recesses `provided therein. Since the bail-shoes are longer than the recesses, the bail is held to the guides and continues to move in the plane thereof. As the bottom of the skip is carried upward by the bails it is rotated upon the links and the bails, and by its rotation its top is forced away from the guides. This movement of the skip causes the links to ride upon the studs provided on the bails until they reach the ends of the slots, thereby positively regulating and limiting the rotationof the skip. Meanwhile and until the skip has reached the limit of its rotation, as determined by the links, the top of the skip is supported by the lower tracks, which are arranged so that the rollers will engage therewith.

By means of this construction the skip is securely held by three sets of shoes, so that accidental dumping in the shaftis'absolutely prevented. The skip can also be used upon inclined roadswithout requiring any additional parts or mechanism to retain same in its proper position. The link forms a positive connection between the skip and the bails and not only regulates the dumpingangle of the skip, but increases its rigidity and stability. Since but few parts are required, the skip can be easily and readily constructed, and the cost of manufacture is correspondingly reduced.

I claim as my invention- 1. The combination with a du mping-skip and its bail, of means pivoted to the skip to permit rotation thereof and engaging with the bail to limit the rotation of said skip; substantially as described.

2. The combination with a dumping-skip and its bail, of a link'pivoted to one of said parts and engaging with the other part to limit the rotation of the skip, su bstantially as described.

3. The combination with a skip, and a bail pivoted to the skip and provided with a stud, of a link pivoted to the skip and provided with a slot engaging with said stud on the bail to limit the rotation of the skip, substantially as described.

4. The combination with a skip-guide, ot' a skip-bail provided with a shoe engaging said guide and movable thereon, a skip pivoted at or near its bottom to said bail to rotate freely thereon, and a shoe on said skip at or near its top engaging with and movable on the same guide to hold the skip against rotation, substantially as described.

5. The combination with a skip-guide provided with recesses and a skip-bail movably secured to said guide, of a skip pivoted to said bail to swing freely thereon, a shoe on said skip engaging with the guide to hold the skip against rotation, a roller secured to the skip at or near its outer edge and a track to engage with said roller whereby the said skipshoe may be disengaged from the guide and the skip upturned,substantially as described.

6. The combination of skip-guides provided with recesses, bails provided with shoes secured to and movable on said guides, a skip pivoted directly to said bails to swing freely thereon, shoes rigidly secured tothe skip and adapted to engage with the skip-guides,means for rotating the skip when said skip-shoes are opposite the recesses, and means secured to the skip and engaging the bail to limit the rotation of the skip, substantially as described.

7. The combination of ski p-guides provided with recesses, bails provided with shoes secured to and movable on said guides, a skip pivoted to said bails, shoes rigidly secured to the skip and adapted to engage with said guides, rollers on said skip, tracks adapted to engage said rollers when the skip-shoes are opposite said recesses to rotate the skip, and links pivoted to the skip and engaging with the bails to limit the rotation of the skip, substantially as described.

In testimony whereof I sign this application, in the presence of two Witnesses, this 4th day of December, 1900.
