'Letters Patent No. 86,926, dated Februa/ry 16, 1869.

IMPROVE!) ELEVATOR-LEG.

The Schedule referred'to in these Letters Patent and making part of the same.

To all whom tmayv' concern:

' B e it known thatI, Grnonenv H. JOHNSON, of the city of Buffalo, ih the county of Erie, and State of New York, have invented a certain new and useful Improvement-in the Construction of Metallic Elevator-Legs;

and I d o hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specilication.

My invention relates to what are technically called .the-indoor legs of an elevator; that is, those employed v Within theV'store-honses for distributing the grain to the bins, and discharging it therefrom.

The usually great height of such legs, and the fact that they require to pass up through the grain-bins, present serious difficulties to' their construction of metal in position at the elevator.

The object of my improvement is to avoid such difficulties of construction, yand the consequent great eX- pense ofthe structure.

` My invention for accomplishing this, consists in constructing the bucket-tubes or leg itself in sections, iinished complete at the shop or manufactory, which can be readily connected in forming the'leg by simply bolting them together, thereby dispensing with the. labor and necessity of riveting the parts under circumstances so impracticable as at the elevator. In the drawings- Figure Iis a side elevation of my improved .elevator-leg.'

Figure II is a rear elevation.,

Figure III is a view-of a fragment of two sections of a bucket-tube, detached.

Figure IV is a view of an adjacent side ofthe same.

Figure V is a cross-section thereof.

Like letters of reference designate like parts in all of the figures.

A A add A' A' represent the sections, forming respectively the front and rear bucket-tubes of an elevater-leg.

B is the head-box, which connects the upper ends of the tubes A A', and receives the head-pulley, over which passes the belt carrying the buckets.

An extension, B', of this box formsthe` spout, through which the grain from the buckets is discharged.

O is the foot-box, connecting the lower ends of the bucket-tubes, in which is mounted the foot-pulley of the elevator-belt. It is provided with the ordinary openings at the bottom and sides, for the passage of the grain to the buckets.

The tube-sections A A' are each formed of sheetmetal plates, D D', the platesv D projecting beyond the ends ofthe adjacent ones D, as shown in Fig. V, and' forming a tube rectangular in cross-section.

These plates are secured together by anglefbars', e e, applied longitudinally; to the outer angles formed by the projecting portions of the plates. D, to which the edges of -both plates are riveted. lThese angle-bars also Aserve to stiften the tubes.

F represents a rectangular ring-casting, formed with two flanges, f and f, at right angles to each other.

-Each end of the sections D D has secured to it one of these anged castings, 'which is'eiiected by riveting to the iiange f the ends of the plates forming the sec tion.

plete at the shop, and two sections, A A', may be connected by the diagonal braces g g, before they are transported to the elevator.

The sections are readily connected together, in forming the elevator-leg, by bolts, 'i i, passing through the' contiguous flanges f f of the abutting sections.

By thus forming the bucket-tubes or elevator-leg in sections, no riveting isrequired to be done at the ele.- vator, While the construction ofthe sections at the shop, With the facilities which it ali'ords for heating the rivets, of light, and convenience in riveting the parts together, enable me to construct au elevator at a greatly reduced expense from that otherwise required. This difference in the cost of construction is an'important item.-

Another advantage and result of my improved construction of an elevator-leg is that of' portability, which the leg thus acquires.

f Having thus described my invention, hat I claim, and desire to secure by Letters Patent, is-

The iron elevator-leg, constructed in sections, substantially as herein described, as a new article'of manucture. V
