Application filed March 28, 1914. Serial No. 827,865.
To all whom t may concern:
Be it known that I, FERDINAND DAVIS, a citizen of the United States of America, residing at Uniontown, in the county of Fayette and State of Pennsylvania, have invented certain new and useful mprovements in Safety Devices for Mine-Cars, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to safety devices'for mine cars and has for its objecttovprovide means, in a manner as hereinafter set forth, to loe operated on a hoisting cage, for controlling the loading of the mine cars upon the cage. Y v
A further object of the invention is to provide a safety device for mine cars, having associated therewith means to permit of the koperation of the hoisting cage independently of the loading of the mine cars thereon. Y
A further object ofthe invention is to provide a safety device for controlling the loading of mine cars upon a hoisting'cage, and operated on the descent of the cage, to whereby the same can be cage, and to lock the car in the rear of the cars released, so that the said rear car will not interfere with that car which is loaded upon the cage.
Further objects of the invention are to provide a safety device for the purpose set forth which is simple in its construction and arrangement, strong, durable, eiiicient and convenient in its use, readily set up, and comparativelv inexpensive.
lVith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more fully described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modications can be resorted to which come within the scope of the claim hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views F igure 1 is a top plan view of a safety .device in accordance with this invention; Fig. 2 is a transverse sectional view; Fig. 3 is a side elevation; Fig. 4 is a longitudinal sectional view.
Referring to the drawings in detail, 5 deloaded upon the 28 elevated. As the ranged a base 1-2, having secured thereto, by
the holdfast devices 13, a vertical extending arcuate rack 14. The rack 14 has itsupper portion bifurcated as'atl5. f i
Mounted upon the supports 8-9 vare transverse ties 16, having securedthereto a longitudinally extending platform 17, which is of greater length than the length .of the pit 6, and upon the upper face ofsaid platform 17 extend the 'trackl rails 18-19.k
The former is provided with vertically disposed openings 20`21 'which aline with openings 22 formed in certain of the ties 16.
The rail 19 is provided with vertically disposed openings 28%24 which aline with the `openings 20-21, and which also aline with vertical openings formed in the ties which are provided withl the openings 22.-
Secured in the supports 8&9, and extended transverselv of the pit 6.V is a shaft 25 having leccentrically mounted thereon a shaft frame 26 which is arranged within and projects forwardlv from the pit 6. The rear weight 27, and the forward end with a trip bar28, the latter being arranged inthe path of a hoisting cage not shown. The weight 27vprovides a counterbalance frame andy is emploved for normally maintainingV the bar frame 26'is eccentrically mounted. the normal position of said frame will be at an inclination with'the weighted end lowered. and Vbv normally setting up the frame 26 in the manner as stated, a pair of vertically disposed stop members 29-30 are normally projected through the openings 21-24. he stop members 29e-30 are pivotallv connected as at 31 to the sides of the frame 26, near the forward end thereof.
Pivotallv connected to the sides of the frame 26. rearwardly with respect to the stop members 29-80, as at 32, are vertically disposed stop members 33`34 which extend through the openings 20-23. As the rear portion of the frame 26 is normally lowered, it is obvious that the stop members 33-34 will normally be in a lowered polend of the frame 26 is provided with a l travels tow-ard the stop members sition, The length of the stop members 29-30 is such that when the frame is in normal position, the said stop members will project above the rails 18-19, and in the path of the forward wheels 35 of the car 36. The length of the stop members 33-34 is such, that when the frame 26 is in normal position, the upper ends of the said stop members will be positioned below the treads of the rails 18-19 so as not to interfere with the travel of the car 36, as the same 29-30 to .be arrested thereby.
When the bar Q8 is depressed by the hoisting cage, when this latter descends to the bottom of the shaft 5, the frame 26 is lowered upon the shaft 25, whereby the forward end of said frame 26 will be lowered, carrying the stop members 29-30 therewith, and releasing' the car 36 so that the latter can be loaded upon the hoisting cage. `When the forward end of the frame 26 is lowered, the rear end thereof is elevated against the action of the weight 27, and as the rear end of said frame 26 is elevated, the stop members 33-34 are carried therewith whereby the upper ends of said stop members 33-34 will be projected above the treads of the rails 18-19, and in advance of a car in the rear of the car 36, so that the stop members 33-34 will engage the front wheels of said car and arrest movement thereof. When the hoisting cage ascends with a car thereon, the bar 28 is released, and the weight 27 comes into action, and will lower the rear end of the frame 26 and elevate the front end of said frame. As the front end of the frame 26 is raised` the stop members 33--34 are lowered, which releases the car, or as the stop members 33-34 are lowered, the
, stop members '29-30 are elevated, so that as the car moves forward, it will be arrested by the stop members 29.30.
To permit of the operation of the hoisting cage, without loading the cars thereon, and to arrest movement of the cars so that they cannot move on the hoisting cage, when the frame 26 is operated, a pair of Genies of .this patent may be obtained for ive cents each, by addressing the stop members 37-38 are provided, which are adapted to be projected upwardly through openings 39-40 formed in the track rails 19-18, and in openings in the platform 17 which aline with the openings 'S9-40. The stop members 37-38, are pivotally connected at their lower ends as at 4l, to crank arms 42, carried by a shaft 43, which is journaled in the members 8 9, and extends into the rack 14. rlhe shaft 43 has fixed thereto as at 44, a lever arm 45 which extends up through the furcation of the rack 14, and is provided with a spring pressed dog 46 adapted to engage in the rack 14 and maintain the shaft 43 in the position to which it has been shifted. rlhe stop members 37-38 extend up through the frame 26, and when the lever 45 is shifted rearwardly, the stop members are elevated so as to project in vadvance of the rear wheels 47 of the cark 36, Vand will arrest movement of the car 36 toward the hoisting cage, whether the frame 26 is shifted by the cage or by the weight 27.
Vihat l claim is ln combination, a track leading to a hoisting cage shaft, a pit arranged below said track, a normally inclined counterbalance frame pivotally supported in said pit and having its forward end projecting into said shaft and capable of being shifted by the descent of said cage, front and rear stop elements pivotally connected to said frame and capable, when the latter is shifted, of beingalternately retracted and projected intothe path of travel of cars to release and arrest travel of the cars toward said cage, and vertically movable stops,
manually operated, and independent of both the hoisting cage and said' first named stop elements, and located intermediate the front and rear stop elements rst named.
ln testimony whereof l affix my signature in the presence of two witnesses.
