. Thenature of thisinvention relates to an improvement in that class of elevating devices.
which 'are employed forreising materiel from the ground to the upper stories of at building in course of construction 5 having for its oh ject tofurnish an apparatus which'will not only elevate the material but will alsoeonvey it to any point desired and return the empty plett'ormzor hoisting-box; and to this end it consists, first, in the employment of-th'e-con- 'veyer or traveler H, shown in the patent of- NelsouU. Thomas hndJhcob H; (lee, dated October 13, 1 868, in connection with a porte ble sectional scaffold for elevatingand conveying'horizontally the material and, secondly, in connection with the said devices a counter weight noting through a Windlass. or drum to prevent the load from-sagging out of its horizontal position when elevated until the hoist- -rope is slackeued, and for returning the. empty hoist-hex to the proper position for lowering,-
as'mo'refully hereinafter set forth.
In the drawing, A A represent two sectional standards, the oneer'eeted inside and thqotlr er outside't'he walls of the'buildin'g in course of construction, kept in position by e girt, A, B is aniron rod stretched between the upper ends of the standards, and O is a. traversing carriage or conveyer, w'hose grooved pulleys u a travel ou-iho sn'uirod. It is provided 'ifl'lfll Elevating Building Material;v and I doldeelare that'the following ispart of this. specification, in
thence a haihb, e pnlleyor .sheave,.o, and a levereateh', d, which engages. with a stop; 0, on the rod B, all parts of the suidcarringe being an ranged to operate .as described in the afore- Isaid Letters Patent. 'D is a-box, in which building material is hoisted, end to it one'endf of the hoist-rope E is attached; fromthe'hox it is led up over the sheave c of the carriage; thence to and through e snatch-block, 'F,.se-
cared to the inner standard A under the rod 13;. thence across to the side of the, outer standard and Have through a, block, F hanging from. it; thence down to a guide-block, F,
at its feet; end thence to anysuitable hoist- --ing--winch operated by steam or animal power, I 1 9 y o sh r deseribe hereinr eonstruction. -Fig. 2 tea perti" 'Itwill be evident that if the hoistrope be wound upon. the winch the box will be elevated until it 'tripper, f, on the rope just above 'it strikes the lever-catch d and I releases the carriage from the stop 6, when the carriage will travel along the rod toward the inner standard; but it will also benotic'edthat the.
weight oi the material will feanse the carriage to move more rap'idlythan is dueto the strain of the hoist'ropmnnd therehylower the box as soon 'as the carriage is releasedgiiiom the stop. which, it not overcome, would remlee the hoisting-gear useless fertile purposes oi" the present invention. I i
To overcome this objection, and also, to ene-.
hle me'to lower the-boxand stop the carriage at any point on the. rod 3, I employ a. counterwe ght operetin g in thefollowing manner: At the. foot of the outer standard I place a frame, G,'in which a. shaft, 4H, is-jourualed in suitable boxes, carrying a drum, '-I, of large diameter, and another, 1",of less (Ila-meter, and, also, outside the front end of the frame a ratchet-fJ', with which engages a pawl, K, under which passes a lever, 'L, whieh is pivoted to the frame to lift the pendent of the ratchet and release the drum-shaft. Aspriug,
M, keeps the lever away from'tlie pawl. A
tension-rope,'hl, has one end secured tothehail of the carriage, and is thence led through e -pulleghloelr, 0, on theouter standard; own through a guide-block, 0', et the foot of said standard thence to the larger drum I, around which several turns are ,hke'n and its end secured thereto 0n the s ller drum 1' one end of a rope, P, is secured thence led through a tail-block, Q, suspended from an arm at the upper part of the outer standard, and to its end is suspended a weight, It. sufliciently heavy to counterbalance the box D when loaded. The ropes N and P are so secured to their respective drums that as one is wound up the other is unwound.
V The box being on the ground and loaded the hoist-rope is wound up on drum to hoist the box. As soon as the carriage is released from the stop a it travels with the box toward the other end of the building. When ever the proper point the movement of the hoist-rope is arrested. In the meantime, as soon as the carriage begins its movement, the rope N is drawn by it, revolving the drum-shaft and winding up the rope I on its drum, raising the counter-weight. The pawl holds the drum while the hoist-rope is sleokened to lower the loaded box to the floor of the structure when itis either unloaded or the box removed and an empty box hooked onto the rope. The operator by means of the lever now disengages the pawl from the. ratchet, when the counterweight will raise the box to the carriage and draw the latter forward to and lock it with the stop e. The hoist-ropebeingslackthe empty box is lowered to the ground by its own gravity, the process being very rapid, it hav- .to regulate the movement imparted to it by the fallingeounter-weigbt. For this purpose the lever L may'have a, short arm carrying abrake-shoe to press ageinst-thevperimeter of the drum as soon as the pawl is disengaged 'by the long arm.
The standards are made in sections the height of a story, (above the lower ones, which are necessarily higher,) so that additionel sections maybe added as the wells progress, the girt A being always placed at the top of the whole and the rod B just below it.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The drums I I of varying diameters, in connection with the tension-rope N attached to the carriage 0, and rope P attached to a counter-weight, R, as described.
2. The combination of the drums I I, ten.- sion-rope N, and rope P having counter-weight R with the pa-w ling devices, as described.
