To all whom it. may concern lBe it known that 'I',-JAMnsA. NoLAN, a citizen ofthe United vStates, residing at Boiwerston, {in the county of iHarrison and State, of Ohio; have invented new and useful Improvements jin Aut'oniatic :Landers, of which the following is a. specification.

" This. invention relates to autoinatic {lenders JfOI' use in ,min-ing lope-rations.

.One. of the mainobjects of: the invention is to provide landers which may be used in conneetionwvitll a: cage of standard construction and which are, automatic in their operation. A further object is to provide simple and eilicient means for moving; the lenders into and I;1-l;;Of.1Qp(-31atiVe position, this means being cage-actuated and car controlled so that thefapparatusas; a hole, is automatic in its operation. \Further objects will pear I from the detail I description.

'A lender shaft: 1- is I'OGliZtbl-Y n ountedaadiiOth 920, Patent jacen-tto o-necside'of the cage shaft S and 'be'lo-wfthe landing-"L. Landeis 2,615 a known typeareisecured', on this shaft and are normally lpositicnedso as to project intothe path of-tra vel offcage Z-Similar landers fl are-secured on aisheft'l rlockably mounted'at 1 the otherqside ,of page shaft 6, "the shafts-1 and l being connected by a rod 3 which is secured at its ends to arms 4 and 5 secured to shaftsl and 1 respectively, arm 4 being directed downwardly and arm 5 being directed upwardly. A Weight arm 6 is secured to shaft land a weight 7 is sccured on thisgufln, this weight acting to rock shaftgl in such-direction as to hold lenders Zand'Q in normalor lowered position.

A control shaft 8is rockebly mounted on landing L-and an operating lever 9 is loosely mounted onythis'sheft to turn about it. The lever {9 includes two spaced arms 10 which are co niliected by Web elements 11 and 12, the outer'f ends of these arms being loosely nloullfiedIon .control shaft 8. A ratchetwheeLlB is secured on shaft 8 between arms 11;0; oflever 9, thisratchet-wheel serving to prevent movement of the lever longitudinally of the shaft. fRa-tchet-wheel L3 is pro Vided with a nontwardly projecting finger 15 adapted for engagement by shoulder 15 "of apawl 16 pivota'jlly mounted at one end at 17, between arms 10 of-lever 9. An L- shaped connecting bar 18-is secured in the upper portion of pawl 16, which is provided with a'lbligitudignally extending groove for this-purpose. Tljie'outer end of bar connected bypin and slot connections 19 to affoikQO secured onthe upper end of a trip red 21. Rod 21 passes through a slot 22 prowided in the outer; end of a lander sha ft operating'ar n23 which is secured at its inner end ,o1,1'lander shaft l. A disc 24; is secured on rod QIhelO ar n 23, and adisc25 directed oppositelyto disc-2a is secured on the trip rjod above a triplever 2,6 rockabl-y mounted intermediate its ends 191 a stuh-sln tp orted bearing b'rackfiis 28. --Rod 21 passes through a downwardly tapering slot 29 provided in lever Qdanda disc 30 is secured on rod 21 beneath lever 26to limit :vdownvt'ard movement thereof. A hinged trip fi-ngerQE-Bl is mounted the-inner end of levee-26, this finger proiectin into the path Eef movement of cageC, The finger 31 -connected'to lever in such manner-that ethe finge'l will be raised when the cage moves upwardly past the same and; when the cage ,ino'ves 'idQWnwardly and st-r' s finger 'lever 26 Will-be rocked so to raise-the outerfiend of this lever. -This arrangement uofo the-fingerfil is similar to that disclosed in my U; S. patent abovereierred to and Ineed'inot be furtherdescribed in detail.

t '27 sup- Arm 23fisconnected by a link 32 to an arm 33 depending from and rigid with ratchetwheel 13. One of the arms 10 of lever 9 is provided with an angularly disposed arm 34 which is connected by a link 35 to a pin 36 carried by an arm 37 secured on the lower end of a shaft 38 which is rockably mounted through a block 39 carried by a plate 40 secured to one of the rails a of approach track A. A tension spring 41 is secured at one end to a second pin 36 se cured in arm 87 beyond pin 36. The other end of spring 41 is secured to a pin 42 which is secured in a block 43 or anchored in any suitable manner. This springis so positioned that, when shaft 88 is turned a predetermined distance in either direction, the line of tension of the spring passes be yond the center of the shaft so that the spring acts to complete the throw of the shaft and to hold the shaft in rocked adjust ment. This spring; arrangement is similar to that disclosed in my U. S. patent for mine car eager dated April 20th 1920, Patent Number 1,837, 944 and need not be further described in detail. A reset block 44 is secured on the upper end of shaft 38 adjacent to rail a. This block is movable across rail a so as to be displaced inwardly of the rail by the wheel of a car traveling down the approach track A' onto cage C. An arm 45 is secured to one end of control shaft 8 and a tension spring 46 is secured at one end to this arm, the other end of this spring being anchored at 47 to rail 64. Spring 46 acts to complete the throw of shaft 8 in either direction and to hold this shaft in rocked adjustment, in the same manner that spring 41 acts to complete the throw of shaft 38.

A contact member 48 is lockably mounted at 50 between arms 10 of lever 9, at the inner end thereof. Member 48 is provided with an upper arm 51 and a lower arm 52, these arms being oppositely directed. Arm 51 is broader and heavier than arm 52 and normally rests upon web element 11 so as to hold arm 52 in position in the path of movement of cage C. With the parts in the positions illustrated in Figs. 1 to 4, in which it is assumed that a car has passed from the approach track A onto cage C; when the cage is raised off of the landers it will strike arm 52 of contact member 48 and will rock lever 10 about shaft 8 and this shaft will be turned by means of shoulder 15 of pawl 16 and finger 14 of ratchet-wheel 13, a suf fieient distance to move spring 46 below the axis of the shaft, after which this spring will act to complete the throw of the shaft and to hold it in rocked adjustment. This serves, to turn ratchet-wheel 13, which is secured on shaft 8, into its extreme position in one direction. This turning of the ratchetwheel serves, through arms 83 and 23 and link 32 to rock shaft 1 in such direction as to raise the landers 2 and 2 out of the path of travel of cage C. During its upward movement off of the landers cage C is raised slightly above the uppermost position of the inner end of lever 9. If the cage, in descending after being raised, should contact with arm 52 of member 48 lever 9 would not be operated since this member is free to turn about pivot 50 and, after the cage has passed, will be returned to normal position by the weighted arm 51. As the cage descends and passes beyond the lenders, it will contact with finger 31 thus rocking lever 26 so as to raise the outer end of this lever into contact with disc 25. This raises trip red 21 so as to raise pawl 16 and move shoulder 15 out of the path of movement of finger 14 of ratchet-wheel 13. Continued upward movement of rod 21 brings disc 24 into contact with the outer end of arm 23 raising the outer end of this arm and rockin shaft 1 a sufficient distance to turn shaft 8, through the medium of link 32 and arm to such an extent as to bring spring 46 above the axis of this shaft, after which the spring completes the throw of shaft 8 and the landers are returned to normal or lowered position by means of weight 7 supplen'iented by the action of spring 46. During this operation of returning shaft 8 to normal or set position, pawl 16 is held raised into inoperative position. After shaft 8 and con sequently ratchet-wheel 13 has been returned to normal position, the cage passes downwardlv out of contact with finger 31 thus releasing lever 26 so that trip rod 21 is returned by gravity to normal position. hen the trip rod is lowered pawl 16 is lowered and rests upon the finger l4, shoulder 15 being positioned outside of or beyond this linger. In this manner the cage is released and the landers are moved into inoperative or raised position thus permitting the cage to pass downwardly in the shaft. the cage acting, after it has passed beyond the landers, to release the landers which are returned to operative or lowered position.

Upon return of the cage to the landine, L, as the cage travels upwardly in shaft Q it will contact with finger 31 which will be raised without affecting lever 26. After passing beyond finger 31. the cage will contact with landers 2 and 2 which will he rocked upwardly and, outwardly a slight distance but will be immediately returned to lowered or operative position after the cage passes by. After the cage has passed beyond the landers it is then lowered onto the lenders so as to be supported, thereby as illustrated. lVhen the cage is in position at the landing L, a car is fed down the approach track A and acts to move the trip block 44 inwardlv of rail a, it being understood that this block was turned so as to extend outwardly across the tread of rail (1, through the medium of arms 34 and 37 and ill) when it'travels past the landers in one direction for rocking the shaft in lander raising direction and for holding the shaft in position to hold said landers raised, means actuated by the cage when it travels past the landers in the other direction for releasing the shaft and roelring it in lander lowerin direction, and car controlled means for returning the first mentioned cage actuated means to operative position.

8. In combination with a landing and tracks leading to and from the landing, a cage movable past the landing and provided with a car-receiving track section, a roclrably mounted lander shaft, landers secured on said shaft and normally projecting into the path of travel of the cage, means tending to rock said shaft in lander lowering direction, a rockably mounted control shaft, an operating lever loosely mounted on said control shaft, interengaging members carried by the lever and the control shaft for turning the latter with the former when the lever is moved in one direction, said lever being provided with a member projecting above and into the path of travel of the cage when the lever is in operative position so as to be struck by the cage for moving the lever in said direction when the cage is raised, connections between said shafts for rocking the lander shaft in lander raising direction when the control shaft is rocked in said direction and in lander lowering direction when said control shaft is rocked in the other direction, means actuated by the cage when it has traveled past the landers in the other direction for disengaging the member carried by the lever from the member carried by the control shaft and subsequently turning the control shaft in lander lowering direction, and car controlledmeans for returning the lever to operative position.

9. In combination with a landing and tracks leading to and from the landing, a cage movable past the landing and provided with a car-receiving track section, landers normally projecting into the path of travel of the cage, a rockably mounted control shaft, an operating lever loosely mounted on said shaft, a ratchet-wheel secured on the shaft and provided with an outwardly projecting finger, a pawl carried by the lever and positioned to engage behind the finger when said lever is in operative position, a member carried by the lever and positioned to be struck by the cage as it travels upwardly past the landers for moving the lever and the control shaft in one direction, connections between said shaft and the landers for raising the latter when the shaft is moved in said direction and lowering the landers when the shaft is rocked in the other direction, means actuated by the cage as it travels downwardly past the landers for disengaging said pawl from said finger and subsequently rocking the control shaft in lander lowering direction, a reset block on one of the tracks, and connections between said block and the lever for moving the block into position to be struck by a car when the lever is moved out of operative position by the cage, said connections acting to return the lever to operative position when the block is moved by the car into inoperative position.

10. In combination with a landing and tracks leading to and from the landing. a cage movable past the landing and provided with a car-receiving track section, a lander shaft rockably mounted below the landing, landers secured on said shaft, means for normally holding the shaft in operative position with the landers lowered and projecting into the path of travel of the rage, an operating arm secured at one end on the lander shaft and provided at its other end with a slot, a trip lever mounted below the arm and provided in its outer end with a slot, a downwardly acting trip finger at the inner end of the lever and projecting into the path of travel of the cage, a rockably mounted lander shaft, an operating lever loosely mounted at its outer end on the shaft, a contact member carried by the operating lever at the inner end thereof and projecting above and into the path of travel of said cage when said operating lever is in operative position, an outwardly projecting arm rigid with and depending from said operating lever, a link connecting said arm and the operating arm, a ratchet wheel cured on the control shaft, a pawl carried by the operating lever and positioned above and engaging with said wheel for turning the same 'with the lever when the inner end. of said lever is raised by the cage, a trip rod passing loosely through the slots of the lander shaft arm and the trip lever and loosely connected at its upper end to the pawl, an abutment member secured on the rod above the trip lever, an abutment member secured on the rod below the lander shaft arm, said abutment member being so related and positioned that upward movement of the outer end of the trip lever will first raise the pawl out of engagement with the ratchet wheel and then raise the outer end of the lander shaft lever so as to return both shafts to o erative positions, and car actuated means or returning the operating lever to operative position.

In testimony whereof I afiix my signature.

JAMES A. NOLAN.
