HOISTING AND TRANSPORTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 434,278, dated August 12, 1890. Application filed April 28, 1890. Serial No. 349,716. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM P. JORDAN, a citizen of the United States of America, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Hoisting and Transporting Mechanism, of which the following is a specification. I

My invention is designed, principally, to take the place of hod-carriers, and to raise material-such as brick and mortarused in the construction of buildings, and to transport the same to the point where they are required fornse, the apparatus being designed for variable heights and for different distances of horizontal movement.

The invention consists, essentially, of a tower composed of sections, and a hoistingcar adapted to receive and raise vehicles which contain material, and a pair of wirerope cables forming inclined ways, or a series of them extending from the tower to the point or points where the material is to be delivered.

In the accompanying drawings, Figure 1 represents a vertical section of the tower and car with the ways in side elevation. Fig. 2 represents a modification of the tower within a building. Fig. 3 is a side view of the brake. Fig. 4. is a cross-section of the tower, showing the cars and track in plan view. Fig. 5 is an enlarged front view of a bottom section of the tower, showing a side section, partly in section. Fig. 6 shows the relative arrangement of the car and the cable and its supportingpulley. Fig. 7 isa perspective view of a cap which holds the sect-ions together.

In the drawings, the tower represented in Fig. 1 is composed of sections built of timber,

as shown, the sections D consisting of front sections a and side sections 1), these sections a and Z) being held together by bolts 0 to form one section of the well for the hoisting-platforms A. At suitable intervals on the front sections a are cross-beams, as shown at d, and beams d to carry the way for the elevator. The side sections b are suitably braced, as most of the strain comes on these sections. I have also shown guys 6 for bracing each of the sections. The interior of the structure shows a hollow shaft clear throughout from top to bottom, and adapted to allow the. free passage of a hoisting platform, which is shown at A in Figs. 1 and 2. These platforms are preferably made in series, one above the other, as illustrated in the drawings. The

hoisting-platform is provided with a hoistingrope f, which runs over a pulley g and is carried thence downward, with suitable guidingpulleys to a hoisting-engine. At the base of the tower I have shown an excavation at B, which is boxed up, so as to be substantially air-tight, and into this the platform fits with approximate accuracy, the fit being such that in case the car should fall the air in the excavation will act as a cushion to break the force of the shock. with tracks, preferably two sets, as shown in Fig. 4;. These, when the platforms are down, are in line with tracks h on the ground by the side of the tower, so that the cars loaded with brick or other materials, maybe run onto the platforms. The platform being down in the pit, as shown in Fig. 1, the cars are run onto the platform from the tracks h. The cars are made small, so that two of them may be ac-. commodated on one track, and one platform will thus carry four. The cars are provided with small wheels 70, adapted to run 011 the tracks. The upper platform being filled, the platform is raised until the next in order comes in line with the outside track, and this is filled, and so 011.130 the end. Then the platform is hoisted until it comes to the cableway 0, where it is desired to transfer the cars to the point where the material is to be delivered. This cable-way is composed of two cables, the outer end of which is fixed in any suitable manner at the discharge-point and the inner ends are carried over guides or pulleys on the corner or side posts between any two of the beams cl, according to the height of the discharge-point or the distance from the tower. The inner ends are then brought down to a drum Z, by means of which they may be put under the proper tension and adjusted as to length. The cars are provided with an upper set of wheels at, set upon journals in the side. These wheels are grooved to adapt them to run on the cable 0, and the cable is set so as to register with the grooves in these wheels. The inclined platform n is also adjustable and is placed oppo- The platform is provided site the beam next below the cable 0. Here the operator stands and runs the cars olf of the platform A onto the cables 0. This platform is set at an inclination downward a little more than the inclination of the cables, so as to support the car in its transfer from the platform to the cable. The lower wheels 70 of the car run upon this platform until the upper wheels get their bearing upon the cables. The cables are set slightly inclined, so that the ears move by gravity from the tower to the point of discharge.

In Fig. 2 I have shown the same form of tower, butarranged to be set inside of a building to lower the empty cars to the ground. From here they are returned to the supplystation, filled, and again taken to the hoisting-tower. The hoist-ropef here runs over a pulley g, controlled by the automatic brake, which, Fig. 3, consists of a lever pivoted at 4, so as to draw upon a strap 2 and grip the wheel 3, which is fixed to or a part of the hoisting-pulley g. A weight 5 applies the brake, and a hand-cord 0, extending within reach of the attendant, allows the brake to be taken off. To the other end of the rope f is attached a weight I, which is heavy enough to return the empty platform A to any desired height, as the operator desires, by applying or releasing the brake. When the platform is filled with the empty cars and the brake released, it will return to the ground.

By this mechanism bricks may be hoisted at any point where they may happen to be, hoisting being done by steam-power, and then they are transpm-ted by gravity to a point where they are to be used, or mortar or any other kind of material may be raised and moved in the same manner, the distance practically depending upon the height of the tower, which may be heightened by adding more sections, each section being guyed.

In Fig. 7 I have shown a socket 0 made of metal, which I use to hold one section from slipping off the top of the next lowest. In practice I prefer sections sixteen feet in length, although the length may be varied.

1 claim as my invention- 1. An apparatus for builders" use, compris ing a tower composed of sections supported one upon the other and provided with openings and inclined platforms thereat, a hoisti'ng cage or platform movable within the tower, a wheel-carrier on the platform, and adjustable tracks consisting of flexible ropes leading from the openings in the tower, substantially as described.

2. An apparatus for builders use, comprising a tower composed of sect-ions supported one upon the other and provided with openings, a hoisting cage or platform movable within the tower, a wheeled carrier on the platform,adj ustable tracks consisting of flexible ropes leading from the opening in the tower, and the drum on the tower for holding the end of the rope and adjusting the same to alter the length of the track, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
