WILLIAM A. JORDAN, OF NEW ORLEANS, LOUISIANA.

BRICK AND MORTAR ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 259,165, dated June 6, 1882.

' Application filed April 5,1882. (No model.)

a citizen of the United States,residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Brick and Mortar Elevator, of which the following is a specification.

My invention relates to an improved means for adjusting the elevatin g-platforms, whereby materials for building purposes may be elevated to different heights and the ropes kept taut; also, to means for taking up the slack of the rope which operates the platforms; also, to an improved means by which the frames of the platforms are relieved from the injurious effects of jars or concussionsin their descent, and also to an improved means for holding the platforms down after they have descended for new loads.

The nature of my invention will be fully understood from the following specification and accompanying drawings, in which latter- Figurel is a plan view of my improved brick and mortar elevator, a small portion of some of the parts being broken away or removed. Fig. 2 is a vertical central section of the same in the line 00 0c of Fig. 1. Fig. 3 is also a vertical section of the same, but in a line, 1 y, at right angles to the line 00 an of Fig. 1; and Fig. 4 is a detail vertical section of one of the posts of the elevator-platforms and the sliding strap with india-rubber block. Figs. 5 and 6 show detail views, side elevation, and plan of a modification of one part of the elevator.

In the accompanying drawings, the stationary guide-timbersA A and the moving frames carrying elevating-platforms B B are shown arranged within a building, 0, the walls of which we will suppose are partly built. The position of the guide-timbers with respect to the walls of the building is to be such that a temporary flooring, g, may be built all around it for the support of loaded wheelbarrows which are elevated upon and moved off the platforms and wheeled upon this flooring, said flooring also serving to support the brick and mortar elevated upon and Wheeled ofi the platforms and dumped or tossed upon suitable scaffolding near where the masons are working. Said flooring also serves the work men as a free passage around the elevator.

The two elevating platforms B B, with their frames, are built alike and of equal proportions, and are placed on opposite sides of a vertical center, between the pairs of timbers A A, so that they may be loaded on different sides, a b, of the building, or from sides at right angles to the street-front c and rear wall, d. Thus arranged, the guided ends of the platforms and their frames will stand parallel with the street-wall c. The platforms, with their frames, are fitted between the grooved uprights or timbers A A, being provided with bearing friction-rollers f f, which extend into the grooves, so as to hold the frames and platforms in true positions and ease the np-and-down movements of the same. At the place where the elevating-platforms receive their loads inclined portions of flooring g are provided for easing the passage of Wheelbarrows upon and off the said platforms, and just above these portions of flooring pivoted catches D D are provided upon the timbers A A, for the purpose of locking down the platforms after they have delivered their loads and descended for new loads. These catches are weighted at their upper outer ends, and they are so arranged that their inner lower ends stand within the vertical passage-way of the platforms, and said ends are struck and moved aside as the platforms descend, and then when the platforms have fully descended the displaced ends of the catches move back to their normal positions and stand above the platforms and prevent an up- 'ward movement thereof until desired, when the operator swings thev catches to one side, out of the way of the platforms.

At the lower ends of the'posts of the frames of the platforms B B strong angular metal straps h, of U or rectangular form, as shown, are applied, and between the bottoms of the straps and the lower ends of the said frameposts india-rubber blocks m 'm are placed for the purpose of forming yielding bumpers or cushions. The side portions of the U-straps are provided with oblong vertical slots at, and through these slots the bolts which connect the straps to the frames of the platforms are passed, the broad heads of the bolts bearing against the straps and extending beyond the slots, so as to prevent the straps from getting'out of place.

By this construction the injurious cfiects from jar or concussion of the platforms when descending with great force or speed will be avoided, inasmuch as the straps will slide up against the india-rubber or other elastic cushions, and thus break the shock and save the machinery from injury.

The platforms are suspended and operated by means of ropes or chains E E, the rope E being passed over a large pulley, F, which is mounted within a strong portable truss'frame, (i, of any suitable construction; and the two ropes are also otherwise arranged and controlled as follows: In rear of the building, at such distance as will suit the desired upward travel of the elevating platforms and frames, an axial bolt, H, is provided, it being firmly supported upon a suitable adjustable piece, H, and to this bolt a large grooved pulley, I, is applied so as to turn back and forth thereon or therewith. The piece H rests upon at'onndation-piece, H anchored by a strong post, H and is connected toit by means of a broad staple, r, and a wedge-key, s, or in the modified manner shown in Figs. 5 and 6. The Staple extends up through an oblong slot, 27, in the piece H. The slot thas adjusting-notches, t on each side, for an anchor-post, H and when it is desired to take up the slack of the lower portion of the rope nearest the pulley I it can be done by removing the wedge, pulling up the post H and sliding the piece H, with bolt and pulley, backward, and then reinserting the wedge and again driving down post H the post now passing through another pair of adj listing-notches, t. The suspending rope or chain E is first made fast to the upper crossbar, 0, of the frame of the elevatorplatform B, then carried over the pulley F, thence down through the upper cross-bar, e of the elevatorplatform B, and then fastened by its end to the drum of a tension and paying-out windlass, J, which Windlass is provided with the usual ratchet-and-pawl-contrivance, j j, as shown; and it may be worked by a crank, handle or wrench, as most convenient. The surplus or slack rope between the Windlass J and platform B is wound upon the Windlass J, and this may be paid out according to the height of location required for the pulley F. The operating-rope E is first made fast to the lower cross-bar, c of the elevating-platform B and carried down under and over guide-pulleys I, applied on sills 1*, to and partly around the pulley I, and then back over and under guidepnlleys Z in other sills Z to the platform B, being passed through the lower cross-bar, 0 thereof, and then fastened to a windlass, J, said windlass having a ratchet-and-pawl contrivance similar to that indicated at j j, these, with the Windlass, being applied to move along with the elevator-platform B, the same as is the case with the windlass J of platform B. This windlass J has surplus rope wound upon it sufiicient for elevating the platforms to any height desired, and this rope is paid out whenever the portable frame G, with pulley F upon it, is elevated from one floor of joists to another of a building. In order to operate the Windlass, its shaft may have a crank-handle, or be made square at its end, so as to beoperated by a lever-wrench.

In order that the frame G may be adjusted from one flooring ofjoists to another,itis constructed to rest upona piece of scantling three by four placed across two of the joists.

By providing the portable pulley-frame Cr and having the ropes E E attached to the windlasses J J, as described, the platforms B B can be expeditiously adjusted, so as to rise to the different floors of joists of a building as the progress of the building of the walls requires, and the landing of the platforms exactly at the points desired can be insured. This is efl'ected by allowing the rope E to unwind from the windlass J and adjusting the pulley-frame G from a lower to a higher plane, and when a temporary flooring, as g, has been constructed upon the floor of joists where the brick and mortar are to belanded the exact or proper adjustment of the platforms and tension upon the ropes are secured by turning the respective windlasses more or less in proper directions and then fastening them by the ratchet-and-pawl contrivanccs. A reverse adjustment of the ropes and frame G with pulley F will adapt the elevating-platforms for landing building materials at a less height-that is, placing the pulleyfirame G upon a lower flooring of joists, and shortening the rope bcdid before thisadjustment was made.

The power is applied to the elevating-platforms through the pulley I, which has arcciprocating movement around or with the bolt H.

The brick and mortar elevator herein described is sccured in position upon joists K resting upon the walls of the building, and by such temporary timbers as may be necessary from the character of the structures being built. As one convenient mode of setting itin position,the following may be adopted: One joist of the respective floors of joists is set aside far enough from anotherjoist of the respective floors to permit the elevator-plattbrms to pass up and down, and the grooved guide timbers A A are secured to the sides of joists and otherwise stayed by timbers until their upper ends can be fastened to joists of the building, which becomes the case as the height of the wall progresses and new floors of joists are set in position. The elevator-platforms are just a little wider than the body of the wheelbarrows in which the brick and mortar are elevated, and the space through which the platforms move is sufficiently long to admit the handles of the barrows a clear passage to and through the temporary floorings, as g, of the building being erected. Floorin gs similar to that shown at g on second floor of joists are provided at each place where the platforms are adjusted to land, so that the empty and loaded barrows may be wheeled thereon to the desired points, and the materials which are elevated discharged upon suitable scaftblding, for use by the masons in the walls.

The operation is as follows: A sufficient number of wheelbarrows being provided for use,half of same are placed on the ground and the other half on the receivingflooring g, and then a filled barrow is wheeled upon the lowest elevating-platform and an empty one on the highest platform. The horse at the pulley I is walked backward until the elevating-platforms are reversed in their relative positions. Then the operation is repeated, the horse this time being walked forward. Steam or other power might be used for operating the elevator.

It is not absolutely necessary to use the two catches D D at the bottom of the guide-timbers A A for holding down the platforms B B. They, however, are useful for unskilled labor. In practice a skillful operator places a loaded barrow upon the platform passes around to the descending platform with empty barrow, places his weight on top of this platform as soon as it is down, and holds it until the full barrow is taken off above.

In the modified plan shown by Figs. 5 and .6 of the drawings I dispense with the staple and wedge-key s. In this plan the wheel I is raised fromthe ground about two feet. In rear of this wheel the post H is buried in the ground solid, and this post bears all the strain brought upon the rope. The wheel Iis made fast to the-slide H, which is provided with a slot, t, open at one end, and also with pin-holes t through which a pin, it, passes horizontally in rear of the post H The platform H is anchored by the post H and the post is stayed by cross-pieces t t, as shown. In practice I shall adopt as preferable and best the modified plan shown in Figs. 5 and 6.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The combination of the pulley I, rope E, and Windlass J, arranged as shown, platforms B B, pulley F, rope E, and Windlass J, arranged as shown, the whole operating substantially as and for the purpose described.

2. The combination of the adjustable slotted pulley-support H, with'pulley I attached, the anchoring-post H, the rope E, and Windlass J, arranged as shown, platforms B B, rope E, and Windlass J, arranged as shown, and pulley F, attached to a portable frame, G, and the whole operating substantially as described.

3. The frames of the platforms B B, provided with sliding slotted straps h h and elastic cushions m m, substantially as and for the purpose described.

4. In combination with the platforms B B, the stops D, arranged partly across the passage-ways of the platforms, so as to be moved on their pivots as the platforms descend, and operating to hold the platforms down after they have descended, substantially as described.

5. In a brick and mortar elevator, the rope E, attached to the windla'ss J of platform B, and then carried down through a cross-bar of the frame of said platform, then around the pulley I, then fastened to a cross-bar of the frame of platform B, in combination with the cord E, attached to a cross-bar of the frame of platform B, and then passed round pulley F, then through a cross-barof the frame of the platform B, and fastened to Windlass J, substantially as and for the purpose described.
