UNITED STATES DANIEL F. LEPLEY, 0F CONNELLSVILLE, PENNSYLVANIA.
HOIS'I SKIP.
Application filed August 31, 1922.
To all whom it may concern:
Be it known that I, DANIEL F. LEPLEY, a citizen of the United States, residing at Connellsville, in the county of Fayette and State of Pennsylvania, have invented a new and useful Hoist Skip, of which the follow ing is a specification.
This invention relates to hoist skips of that type utilizing a bottom closure which, when moved to open position, forms a chute to facilitate the delivery of the contents of the skip. These combined chutes and closures have been operated by means of tracks provided for that purpose, one form ofthis type of skip with its operating means being disclosed for example in Patent No.
1,304,784 issued to me on May 27, 1919 and Patent No.- 1,379,869 issued to me on May 31, 1921.
Bottom closures of the kind mentioned have been found objectionable under some conditions. For example if a skip is brought to a stop at a point where the bottom closure is partly open and for some reason it becomes desirable to reverse the'movement of the skip, it has been found impossible readily to lower the skip because the material carried thereby has become packed back of the partly opened closure or chute and thus interferes with the return movement of said closure under the action of the closing mechanism provided therefor.
One of the objects of the present inven tion is to overcome the disadvantages found in skips of similar types heretofore made by utilizing an undercut gate forming a part closure is materially reduced, thus producing a quicker and easier action of the parts.
A further object is to provide a skip so shaped as to reduce breakage of coal or other material to the minimum when delivered thereto, the load being more accurately cen-- tered than heretofore;
Serial No. 585,540.
With the foregoing and other objects in details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.
In the accompanying drawings the pre ferred form of the invention has been shown.
In said drawings- Figure 1 is a side elevation of a hoist skip embodying the present improvements, one of the chute operating tracks being shown.
' Figure 2 is a vertical section through the bottom portion of the skip and showing the combined closure and chute extended to delivering position. I
Figure 3 is an enlarged section through a portion of the skip and taken on the line 33, Figure 1.
Figure 4: is a similar View showing a slightly modified form of the structure.
Referring to the figures by characters of reference 1 designates the body portion of the skip, the same being secured within a suitable frame 2 adapted to be guided in the usual manner within a mine shaft. The skip is provided with an inclined bottom 3 the lower edge of which terminates back from the plane of the wall 4 of the body and the lower portion ofthe wall 4 merges into a downwardly and inwardly inclined bottom section 5 spaced from the bottom 3 and cooperating with the upper portion of the bottom 3 to form a hopper. The side walls of the body extend outwardly beyond the bottom portions 5 and have their free edges extending from the lower edge of thebottom 3 to the lower edge of the Va11 4 and along lines intersecting the plane of the wall 4.
Reenforcing strips 6 aresecured to the sides of the body and extend downwardly below the lower end of the bottom 3 thus to form bearings 7 in which is mounted a .pivot rod 8. the side wings 9 of a combined chute and closure 10, the bottom of this chute being adapted to extend below the bottom 3. The side wings 9 are provided between their ends with a segmental gate 11 adapted to close On this rod are pivotally mounted the space between the bottom portion 5 and the bottom 3 when the chute bottom 10 is extended upwardly as in Figure 1. Thus the gate 11 will support the contents of the body 1.
The wings 9 lap the outer faces of the sides of the body and the gate 11. is not connected to these wings but, instead, to mental supporting plates 12 riveted or otherwise secured to the bottom of the chute 10. The side walls of the b'odyare adapted to extend between the win-gs 9 and segmental plates 12 as clearly shown in Figure 3.
A supporting frame '13 is arranged :under the bottom 3 of the skip and has a bell crank 14: fulcrumed thereon at 14. One arm of this 'biell crank has a roller 1-5 adapted to work within a track 1'6 located in the path o E movement of the roller. The other arm oi the bell crank is connected by a link 1? to the inner end portion on the chute 10.
By referring to Figure 1 it will be noted that when the chute is closed the upper free end thereof is substantially in line with the reentorrcing strips 318 on the corresponding face of the body 1 and will not, therefore, become hung upon any of the structure within the mine shaft. Furthermore when the parts are thus located the load is supported by the gate 11 situated adjacent the center line of the skip. It will be apparent, by referring to Figure 1, that the load will.
be substantially balanced within the skip because the pocket formed below the bottom portion 5 and back mt the chute 10 is 'not shifted thereby so as to cause the bell crank 14; to transmit motion throi-ig h link 17 to the chute {10. Thus the chute wi-ll be swung from the-position shown in Figure 1 to the position shown in l igu-re 2, the-gate 11 passing from under the load and being brought to a position where it will serve as a means for deflecting the outflowing stream of material into the space between the gate 11 and the bottom of the chute 10. The downward movement ot the skip will result in the re versal of the i'novement of the chute and if this reversal should take place before all Of the material has been delivered from the be no wasteof material and the-re will be no danger of the skip becou'ii-ng stalled in the shaft.
If desired the segmental plates 12 can be offset where connected to the gate 11, as shown at 19 in Figure 4. Thus supporting rollers 20 can be located on the sides of the body 1 at proper points to engage and support the edges of the gate when closed. By providing these rollers the 'segn'iental plates will be relieved to a large extent of the Weight of the load to wl-ri'cli the gate is subj-ected'.
As shown in Fi-gi'ire 1 one wall oi the body is preferably curved, as at 21 thus to overhang the bottom of the skip, this curved wall extending to the top of the skip and leaving.
an inlet space 22 through which material can be delivered to the skip. Bly curving the wall 21 located opposite the point of loading the coal or other material entering the skip in a stream will come against this curved wall and be deflected downward-1y along curved lines, thus reducing breakage to the minimum. s
It will be noted that when the chute is closed it is not in vertical position. Thus it can travel more quickly from its closed position to its lowered or "delivering position than would be possible should the closed chute be vertically disposed and the degree of movement correspondingly increased. By thus reducing the travel quicker and easier action of the chute can be ell'eoted.
Importance is attached to the use of the external hangers 6. These hangers act as a bail or sling to support the outer end of the hinge shaft 8 independently of the support the sha-ft gets from its attachment to the outer end of the unsupported p-la-teor bottom 3 which, itself, is not strong enough to carry theload. 'Dhus the stntictu're is materially strengthened.
