Specification of Letters Patent.

Patented March 16, 1909.

Application filed May}, 1906, Serial No. 314,829. Renewed March 14, 1907, Serial No. 362,416. Renewed June 16, 1908. Serial No. 438,880 i To all whom it may concern:

Be it known that 1, Asnnn LAMnEnT, a citizen of the United States, and aresident of Newark, in the county of Essex and State of at any desired height or point in it's; transit.

The improved skip or load carrier refer ably consists of two arts or sections, inged or otherwise adjusta l united, so that it can be opened and close it is provided with points of connection with the hoist rope so arranged that the su porting effort of the hoist rope automatica ly closes the two sections together and holds them closed during the tiine'the skip is suspended from the hoist rope. In addition to. this, other points of connection are provided on each section and a second rope, called a tripping rope, is employed, so arrangedthat the support of the skip can be transferred from one rope to the other and when transferred to this second or tripping rope the two sections of the skip are separated and the skip is-opened to discharge its load. The hoisting rope is operated thus made taut the skip opens whenever and by a power driven drum in the usual manner;

the tripping rope is provided with a device for taking up the slack, called a take-up device; this consists of a suitable support or standard with a weight and pulley; this rope. is also'provided with a device for checking its movement so that it can be made tohalt -and take the weight of the loaded skip; when the hoisting rope is slacked and the tripping rope wherever the change of support from one rope to the other is made.

' I have shown my iinprovedskip in connection with a derrick but the arrangement of,

the hoisting and conveying apparatus may be widely varied.

The accompanying drawings illustrate the invention.

liigurel. shows the improved skip coniiected to the haul rope and the tripping rope; Fig. 2 is a view at right angles to Fig.

1; Fig. 3 shows the skip in its open position,

the support having been transferred fronr "support, and there is a chain 25 with hooked terminals 26, 27 to detachably engage with the

links

28, 29 pivoted at 23, 24, as described. Therc is an iron I-bar t with a perforated ear 6, and this bar has loops 30 through which the chains 25 are passed. There is a hook 31 fixed to the pulley block p and the hoist rope it passes around the pulley 32 in the pulley block 2). The position of the exterior points of support 23 and 24 on the skip a are so fixed with respect to the hinge 22 and the meeting lineof the two sections 20 and 21 that the supporting effort of the hoist rope h acting through the chain 25 operates to draw the two sections 20 and 21 together. two sections may be locked together and 34 is a pin fixed to the end of a section of chain by which the clamp 33 is locked in position this is only used when the skip is detached from any hoisting apparatus and is located on a support beneath it, the clamp is not a necessary element but is useful when the filled skip istransported on a platform car, for instance. On the outside of the skip at or near the center and near the lower edge are hooks 40, 41, one on each section. tis a trip ing rope connected with the ring 44; 43 is a iiook also connected with the ring 44, and there is a chain or flexible connection 42, the opposite ends of which engage the hooks 40 and 4] and serve to connect the hook 43 therewith. 45 is a flexible connection between the ropes t and 71 it extends from the ring 44 on the tripping rope t to a perforated car 46 on the pulley block 1). Pulley block p is of suiiicient weight to overbalance counterweight 64, thus enabling the o erator to lower the pulley blockwhen no s ip or load is connected therewith.

Referring to Fig. 4, 10 is a vertical mast on the rotating platform 12 pivoted at 14. The

33 is a clamp by means of which the boom 11 is pivoted at 13. 15 is-a brace fixed at one end to the earth and at its opposite end to the top of the mast. There is a m e 16 passing over the pulleys 50, 51, ,52, an a pulley at the bottom of the mast to the power driven drum 53. There is a rope 17 passing over the guide pulley 18 and engaglng thegroove in the rotating platform 12. This is controlled by a power driven drum 54. The hoist rope it passes from the power driven drum 55 over a pulley at the bottom of the mast 10, a pulley part way up the mast, and a pulley near the outer end of the boom, then around the pulley 32 in the block p and is fast to the link 56 at the end of the boom. The tripping rope t extends from the ring 44 over a pulley in the outerend of the boom 11-, over a pulley near the bottom of the mast 10, under a pulley below the mast 10, passes four times around the drum 60, thence under the pulley 61 at the bottom of the fixed standard 63, over pulley 62 at the top of the standard 63 to the weight 64. This weight takes up the slack in the rope t between the rin 44 and the weight 64. The drum 60 is contio led by an angular lever 80 constituting a foot brake this is pivoted to a suitable support at- 84 and is connected by a link 81 with an arm 82 fixed on a transverse shaft 88 journaled in the bedplate 90. The drum 60 is rotatably .mounte on the bedplate 90 and consists of i the friction disk 83 and the pulley 79 fixed thereto. Rope t is passed around the pulley 79 three or four times to give it the necessary friction and the friction disk 83 is shrrounded I by a steel band 85 fixed at one end tothe shaft 88, and at the other end to, an adjust- I able bolt 86. The steel band 85 is provided with wooden shoes 87 which on age the periphery of the friction disk 83; w en the arm 82 is turned by the depression of the lever 80,

. friction is ap lied to the disk 83 and the I lows:

grooved whee 79 is stopped in its rotation; this checks the movement of the tripping rope t. The link '81 may be of any linear extent and may be substituted by a rope.

The 0 eration of the apparatus is as fol- Vl hen the skip a is loaded the drum 55 is started, the hoist rope it exerts a supporting effort on the skip a through the pulley block p and chain 25 ;.this su portin eflort draws the two sections 20 an 21 of t e skip it together. When the ski has been carried to a sufiicient height the com is placed in the necessary position to locate the skip a over the point of discharge. Here the ski a is lowered more or less and while being lowered lever is depressed andthe brake band is applied to the drum 60 at or about the height where the discharge of the skip is desired, while the hoist ro e h is still lowering but immediately after 0 ecking the movement of the tripipng rope t, the section 45 conneein the two ropes t and it becomes taut and t e supporting effort is placed upon F'Tthe rope-t y'vhile the rope it becomes slack; this results in changing the points of support from 23-and '24 to 40 and 41, separates the sections 20 and 21 of the skip, and the load is dropped. By slacking aw ay on the rope t and hauling on the ropeh, the skip is again closed and this change from one supporti n nope to the other may be made whenever an wherever it is desired to open or close the skip. The power driven drum 55 is a means for varying the ion th of the hoisting rope and the drum 60 with the take-up device and foot brake is a means. for varying the length of the tripping rope. v i
