ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 478,263, dated July 5, 1892. Application filed November 4, 1891. Serial No. 410,860. (No model.)

To all whom it may concern:

Be it'known that I, JOHN R. MOSS, a citizen of the United States, residing at WVebster, inthe county of WVestmoreland and State of- Pennsylvania, have invented certain new and useful Improvements in Elevators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to elevators for hoisting building materialsin the erection of buildings; and it consistsin certainimprovements in the construction of such apparatus, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side view of an elevator provided with my improvements. Fig. 2 illustrates the device in sectional front View. Fig. 3 represents an inclined way for the lower end of the elevator. Fig. at illustrates the links and lifters.

On a shaft a, having its bearings in suitable frame work, are mounted two chainwheels A, and on a lower shaft b are two other chain-wheels A, the elevator consisting, mainly, of two endless chains B, passing about said wheels and connected at intervals by cross-bars to which are secured lifting devices for carrying up bricks or other materials. Each of the endless chains B is formed of links 0 and (1, arranged alternately in the chain, the link 0 being oblong and square in form and the link (Z being in the form of a plate, with its ends bent over toward each other, so as to hook at either end to a link 0, as shown. The chains B are connected by horizontal bars f, which are about one foot apart, the ends of each of said bars extending into two links (I of the chains. The bars f are usually widened where they rest in links d, as seen at 6, so that they fit looselyin said links. The studs or projections t' on bars f are to prevent said bars slipping endwise in the links. Fastened to each of the barsfis a litter O, which is formed of a number of rods or hooks g, which are formed with angular bends and are suitably constructed to receive bricks. The hooks g are properly spaced apart, so that each of the lifters will readily receive a single brick.

D indicates an inclined way mounted on' a frame at the lower end of the elevator and formed of parallel rods h, secured in a frame E, said rods being inclined downward toward the elevator with their free ends near the vertical plane of the bars f, carried by the chains B. The rods h are so spaced apart that as the lifters O are raised by the elevator the hooks g of each lifter pass between the lower ends of said rods, so that a brick lying across said rods at their lower ends is caught by the litter and carried up by the elevator. The lower ends of the rods h are turned up slightly, as seen at m, to stop the bricks sliding down the inclined wayD at the right point. At the top of the elevator another inclined way D is secured in position to receive the bricks from the elevator as the lifters pass over the upper chain-wheels and move downward. The inclined way D is provided with parallel rods h, which are inclined downward from the elevator and properly spaced, so that the upper free ends of the rods are in position for the hooks of the lifters to pass between them as the lifters go downward after discharging their contents to the inclined way D.

The shaftsof the chain-wheels may be rotated by anysuitable means, and the links of the chains B being detachable the elevator may be lengthened or shortened, as desired.

The bricks, being placed on the inclined way D, slide down the way to the elevator, and the latter being in operation the lifters 0 each take a brick from the inclined way as they go upward. the upper chain-wheels and commence their downward movement they discharge their contents to the upper; inclined way D, and the bricks slide down'the latter from the elevator.

I claim- An elevator having a double chain with connecting cross-bars fand oblong links at right angles to each other, the said cross-bars f being provided with hook-rods and end studs, substantially as shown, and for the purpose specified.

In testimony whereof I have affixed my signature in presence-of two witnesses.
