M-AGHINE FOR LOWERING 1013, 6w. No. 275,863. Patented Apr. 17,1883.

NITED STATES CHARLES RUNDLETT, OF FARMINGDALE, AS SIGNOR OF ONE-HALF TO EBEN D. HALEY, OF GARDINER, MAINE.

MACHINE FOR LOWERING ICE, 84.0.

SPECIFICATION forming part of Letters Patent No. 275,863, dated April 17, 1833.

Application filed November 18,1882. (Model) To all whom it may concern:

Be it known that I, CHARLES RUNDLETT, of Farmingdale, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Machines for Lowering Ice, &c., which improvement is fully set forth in the following specification and accompanying drawing, which is aview in perspective of the invention in position to lower ice, &c.

The object of the invention is to facilitate thelowering of ice, &c., into the hold of a vessel or other place where guides for the drop cannotbe used to advantage.

In the drawing, M is the drop upon which the ice or other merchandise is placed to be lowered. This drop is made in two parts, It" and It, hinged together at the bottom at l, and being made deeper at the inner than at the outer edges. The leaves, upon striking the bottom of the hold, swing upon the hinges at l, and the outer edges drop down, thus forming a double incline, and the ice or other merchandise placed on the leaves 70 and it of the drop slide off and relieve the drop, which is re- 2 5 turned to place, as hereinafter described. To the corners of this drop are fastened the four ropesjjjj. These ropes are wound around the two shafts a a, and serve to raise and lower the drop. The shafts are supported upon the 0 frame-work composed of the sills n n and 0 0 and the uprights dd dd, the whole being suitably braced to makeit firm. Upon the shafts are the two gear-wheels b b, which engage each other, as indicated, and upon a is the brake i, 5 by which the whole is regulated. Upon one of the shafts, a, is wound the rope g in an opposite direction to the ropes j j. This rope passes along over the pnlleyf, and has attached to it the weight 0.

The whole operates as follows: Two cakes of ice may be placed upon the drop-one on k, the other on k. This weight carries the drop down, the fall and return being regulated by the brake i. This unwinds the ropes jj, &c., and winds up the rope g, which raises the weight 6. When the drop M strikes the bottom of the hold, the leaves k 70, striking upon the innersides,eachcantsoutward and theiceslides oft, thus delivering one cake on each side of the vessel. The drop, being relieved of its weight, is at once returned to place by the rope g and weight 6.

The rope 9 may be carried over a pulley on the vessel, or the weight may be permanently located on the wharf. ,5

The drop M may be made solid and the tip of the load regulated by loading the ice to the one side or the other, and anyconvcnient power may be substituted for the weight 6.

I claim- 1. A machine for lowering ice, 81c, composed of the weight a, and \vindlasses a. a, having wheels I) b thereon, in combination with the drop M, all connected and operating by ropes g and jjjj, or their equivalents, substantially as de- 6 scribed, and for the purposes set forth.

2. The combination of the weight 6, and windlasses a a, having wheels I) b and brake i thereon, with the drop M, all connected and operated by ropes, as fully described.

3. The drop M, composed of the two leaves k it, connected by hinges at Z, operating as and for the purposes set forth.

CHARLES RUNDLETT.
