ELEVATOR.

SPECIFICATIONforming part of Letters Patent No. 330,792, dated November 17, 1885.

Application filed April 22, 1885. Serial No. 163,062. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN A. LEGG, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation of an elevator embodying my improvements. Fig. 2 is a front view of the same. Fig. 3 is a sectional view of a part of the gearing on a larger scale. Fig. 4 shows the lower end of the elevator. Fig. 5 shows the lower end of the adjustingscrew. Fig. 6 is a horizontal section on line as 00. Figs. 7 and 8 show the sliding powershaft. Fig. 9 is a sectional view of the parts at the upper end of the screw. Fig. 10 is a side view of the elevator-frame. Fig. 11 shows a modification of the parts in Fig. 6, and Fig. 12 a modification of those in Fig. 5.

In the drawings the elevator is shown as having a stationary frame consisting of the front uprights, A A, rear uprights, B B, bottom sills, A A, top sills, A A, and intermediate sills, A.

The elevator proper consists of a chain or chains, 13, carrying buckets B, the chains engaging with wheels 13 at the top and wheels B at the bottom.

O is the shaft at the top, which carries the upper wheels, and G the bottom shaft for the wheels B. These latter parts are supported in an adjustable frame having side pieces and as many cross-bars as are necessary.

As shown, the side parts are constructed of bars D D, at top and bottom, connected by two bars, D D These latter are so arranged, as will be seen, as to leavea passage-way between them for a purpose to be described, there being one of these passage-ways on each side of the elevator.

The movable elevator-frame is connected with the stationary frame by means of a shaft, E, which, as shown, is mounted in bearings at e at the upper end of the last said frame, and is made either insections, as in Fig. 5, or continuous, as in Fig. 12. The connection between the two frames is effected by means of a screw-shaft, F, which is carried by the movable frame and secured thereto by means of the cross-bars d d, the shaft having collars, which prevent it from moving endwise, but permit it to rotate in the bearings on said crossbars. At E there is a nut carried by the shaft E, with which the shaft F engages, it being secured as in Fig. 5 or Fig. 12, or in other suitable way. If the screw-shaft be rotated in one direction or the other, the movable frame will be raised or lowered, as will be more fully hereinafter described.

The devices by which power is imparted to the chains, and also those by which the screwshaft F is rotated, are constructed and arranged as follows: At H there is an engine, which may be of any preferred form. It drives a wheel, h, which is connected with a wheel, h, by a chain, h. The shaft h which carries Wheel h, also has a second chain-wheel, h, which is connected by chain h with a wheel, E on shaft E. This wheel is loose thereon, and is formed with an elongated hub or sleeve, E to the outer end of which is keyed a bevel-pinion, I.

J is a shaft mounted at right angles to the shaft E. At the lower end it is supported in the bracket having arms J and J which are provided with a bearing at j for the lower end of the shaft J, and atj with a bearing for the sleeve E The wheel I engages with a bevelwheel, I, carried by the shaft J. It will be seen that the wheels E and I will revolve freely independently of the shaft E, and also that the bearing-brackets J and J can be swung into any desired position without varying the working relation between the bevelwheels I and I. At the upper end of shaft J there is a bevel-wheel, K, meshing with a wheel, 0 on shaft 0, this shaft being extended somewhat beyond the elevatorframe, and mounted in a bracketat 0, carried by another bracket, 0*, secured to the frame, and which has a bearing at k for the upper end of shaft J. The shaft J is grooved and fitted to a feather or spline carried either by the wheel K or the wheel I, so that said shaft can be moved longitudinally relative to said spline or feather and still have a rotating engagement therewith.

The manner of transmitting the power of 100 the engine to the shaft 0 will be readily un derstood from the above description, the work-- ing relation between the engine and the last said parts being constant in whatever position the movable frame is located.

Power is taken from shaft 0 for the purpose of raising the elevator or lowering it relative to the shaft E as follows:

L is a chain-wheel on said shaft, and L a similar wheel on a supplemental shaft, I, mounted in the movable frame, there being a chain at Z, which unites the wheels L L.

f is a bevel-wheel on the end of shaft F, and rotated in one direction or the other by the beveled pinions m m. These are carried by a sleeve, M, joined to shaft Z by a feather, and provided with any suitable shipping mechanism. When it is desired to rotate the screw F in such way so as to raise the movable frame, the pinion m is slipped into engagement with wheel f, and when the screw is to be oppositelyrotated the other wheel, m, is brought into engagement. WVhen the shaft F is to remain stationary, the sleeve M is so situated as that neither of the wheels m m can engage with wheel f. The material which is carried to the top is delivered to one or more chutes, N, which in turn deliver it to diverging chutes N N From these the material passes to carriers 0 0, each consisting of one or more chains, 0, and cross-bars 0. The carrier 0 delivers material to a hopper, P, from whence it passes to the carrier 1), and the carrier O delivers its material to a similar hopper, P, and carrier 19. The carriers 19 p are arranged to run backward either horizontally or somewhat inclined, and they deliver the material to the point ultimately desired. These various carriers may be constructed in any of the now known ways.

Q is the shaft through which power is transmitted to the various carriers above mentioned, O O p p. This shaft Q has a wheel, q, joined by a chain, q, with a wheel, Q, on the shaft h".

R R are bevel-wheels on shaft Q, one driving the carrier 0 by a bevel-wheel, S, and the other driving carrier 0 by a bevel-wheel, S. By means of these parts of the mechanism I am enabled to elevate the material from a boat, car, or other receptacle in large buckets and subsequently carry it to the points of ultimate delivery in smaller masses, and there fore effect the unloading of such receptacle very rapidly. At or near the lower end of the movable frame I employ adjustable braces, as shown at T, they being held in guides or other supports carried by the stationary frame. They bear against the side pieces, D, of the movable frame, and are preferably provided with anti-friction rollers t, to avoid any friction when the movable frame is being raised or lowered. At the lower end of the elevatorframe means are provided for protecting the buckets, so that they shall not be pressed with too great force upon the material below, and so that they shall not scrape the bottom of the receptacle which is being unloaded. As shown, these consist of a cross-bar, U, and supporting,

bars a, secured to the lower end of the bars I), the cross-bar U lying below the path of the buckets.
