HOlSTlNG AND CONVEYING APPARATUS.

FJZPECIFEATION forming part of Letters Patent No. 325,328, dated September l, 1885 Application filed October l, 1884. (No model.)

fo a/ZZ whom it may concern,.-

Beit known that I, LEVI EARTH, residing at Chicago, in the county of Cook and State ot' Illinois, have invented certain nciv and useful Improvements in I'Ioisting and Conveying Apparatus, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure l is a side view of a hoisting and conveying apparatus embodying my invention. Fig. 2 is a detail, in perspective, of a supporting-hook forming a part of the conveyor. Fig. 3 is a top view of one of the trucks or cars and of the temporary or movable track. Fig. 4 is a detail, the same being a side view of a part of the hoisting and traveling gear. Fig. 5 is an edge view of the same, and 6 is a detail of the means employed for suspending the cable Without undue friction. i

Like letters of reference indicate like parts.

The object of my invention is to provide improved means for hoisting and conveying heavy materials, such as stone and timber, for building pu rposcs.

A A representtemporary or portable tracks. B and C are cars on the tracks A A.

D D are comparatively high posts mounted on the said cars. These trucks or cars, including the posts'D D, are strong structures, and the said posts are well braced. I load the cars for use, as indicated at a a, Figs. l and 3, and make them broad, so that when thus weighted or loaded they Willnot be liable to be tipped or tilted. The cars may also have removablesiding b Z), if such siding be deemed expedient. To one or both cars I apply a Windlass, E.

F F are pulleys or anttfriction rollers applied to the posts D D.

G is a stout cable made, by preference, of strands of Wire in the usual manner. This cable passes from one windlass upward over one of the rollers F on one of the posts D, to and over a roller, F, on the other post D, and thence dowward to the car below it, to which it may be secured either by being applied to a windlass on thatcar; or it may be secured at that end in any suitable way. The opposite end of the cable may either be secured to the windlass there located or Wound once or more around it, so that the cable may be made more or less tight by means of the windlass, as indicated.

H H are ropes or guys, which may be employed, if deemed necessary or expedient, for the purpose of further securing the posts D D.

It will. be perceived that the parts now described furnish, in their essential features, an elevated cable, which is portable or movable, as it is supported indirectly on trucks ada-pted to he moved on ways or tracks. It will also be perceived that provision is made for making the said cable more or less slack, that the cable may with facility be suspended at different heights, and also made inclined; but the provisions made for altering the height of the cable for making it more or `less slack, and for rendering it inclined are comparatively minor but distinct features of this part of my invention, the chief feature thereof' being the elevated traveling cable, which I employ for the purposes hereinafter set forth.

I is a geared Windlass or hoisting drum attached to one ofthe cars.

J is a pulley in a block, J', depending from the cable G and clamped adjustably thereon by means of a set-screw, K.

L is a block, and L is a pulley turning therein.

IWI is a wheel or traveler, also turning in the block L and arranged above thepulley L.

N is a block, and N is a pulley turning therein. The upper end of the block N is beveled, as is clearly indicated in Fig. 4.

O is a hook or catch pivoted to the block L, and the block N is open, as shown at d, Fig. 5, to permit it to be engaged by the hook C.

P is an arm projecting rigidly from the block L.

Qis a hook on the lower end ofthe block N.

R B are lifting hooks or grapplers applied to chains RIt', adapted to be supported by or suspended from the hook Q, which may be swivel-jointed to the block N.

S is a rope or cable attached to the Windlass I, and passing thence up over the pulley J, thence over thc pulley L', thence under the pulley N', and thence up to the arm I? to which it is attached. I Will state that an arm, P,

may be attached to each side of the block L, and that these arms may he connected at their lower ends by a rod or bolt of iron, to which the rope or cable may be attached in case it be deemed best to give the greater stength which two arms instead of one would furnish.

T is a cord or rope attached to the upper end of the hook O, and also secured in any suitable way to the car or some fixed part, or so depending from the said hook that the said cord maybe grasped with convenience for the purpose of drawing the hook O out of engagement with the block N, it being understood that the weight or position of the said rope is such as not to prevent the lower part of the said hook from hanging freely pendent and in such a position as to engage the block N automatically as the latter is raised to it.

vIt will now be perceived that the hook O may be drawn from its engagement with the block N with facility by means of the cord or and may be there uncoupled.

rope T; that the block N may then be lowered by turning the windlass I in the proper direction; that the hooks or grapplers R R may then be applied suitably to a block of stone, U; that the chains R R may then be linked to the hook Qif they are not already thereon, and that the block U may then be hoisted by turning the windlass I in the opposite direction, and that the block N will be engaged and supported by the hook O as the said block and hook come in contact with each other. Provision is made by adjusting the cable G vertically, or suspending it at such a height, that the block U will be supported at the elevation desired when the block N is engaged by the hook O. As the tackle now described begins to take its load, the weight of the load will be supported by the cable G, and this weight is usually sufficient to produce such an inclination in the cable as to prevent the block L from being drawn toward the block J while the load is being hoisted. After the load has been hoisted in this manner I slack or unwind the cable S, and, as the load cannot descend, it will, owing to the inclination of the cable G, already referred to, move or ride along automatically toward the place where the load is to be deposited, the wheel M then traveling on the cable G. After the load passes to a point above or nearly above the place at which it is to be deposited, Istop further travel by means of the windlass I, and if I then turn thatwindlassin sucha direction as to slacken or unwind the cable S, the load will descend to the place where it is to rest, If the cable G has not sufficient slack for the purpose referred to, it may easily be made more slack by turning the windlass E in the proper direction. After the load has been uncouplcd all the parts may be returned to their orginal position for another load through the instrumentality of the windlass I.

In order that the position on the cable G of the hoister and conveyer tackle may b e regulated with certainty, I employ a'brake or brake mechanism in connection therewith, and this part of the apparatus I will now proceed to describe.

V V are levers pivoted to the block L and intersecting each other at their pivotal point. The lower ends of these levers are formed, as is clearly shown at f, Fig. 5, to operate as brakes upon the cable G.

W is a pulley near the outer end of the lever V, and WV is a like pulley or roller turning in astandard,W, projecting from the block L.

IV is a cord or ropepassing over the roller W', roller W, and passing thence to the upper end of the lever V, to which it is attached. The lower portion of the cord W is arranged where it may be conveniently reached, and when this cord is tightened the brakes f f will be compressed upon the cable G and prevent the travel of the wheel M thereon, thus retaining the load above the place at which it is to` be deposited.

It will be perceived from the foregoing description, and on reference to the drawings, that a block, U, or other load may be hoisted and conveyed to its destination with facility, and that the load maybe deposited at any distance from the Windlass I in the direction in which the cable G runs according to the length of the said cable. It will also be perceived that the load may be carried or conveyed in a transverse direction, or in a direction at or nearly at right angles to the cable G. For example, in laying a broad and long pier or foundation built of heavy material-such as stone-the blocks of stone may be laid one after another across the pier, and also along the length of the pier, the cars C C being moved along their tracks for the latter purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A hoister and conveyer in which are combined, substantially as speci'ed, temporary or portable tracks, trucks orcars,an elevated cable supported by and suspended between the said trucks or cars, a traveler or conveyer on said cable, brake mechanism carried by the traveler or conveyer, hoisting-tackle supported by or depending from the traveler or conveyer, and tackle for working the traveler or conveyer and the brake mechanism, and for raising and lowering the load, for the purposes set forth.

In testimony that I claim the foregoing as my own I hereto affix my signature in presence of two witnesses.

LEVI EARTH.
