ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 447,435,'dated March 3, 1891.

Application filed October 27,1890. Serial No. 369,430- (No model.)

To aZZ whomt't may concern.-

Be it known that I, THEODORE LEONARD MARVEL, of Taunton, in the county of Bristol and State of Massachusetts, have invented an Improved Elevator, of which the following is a specification, reference being had to the accompanying drawings, making a part hereof, in Which Figure 1 is a side elevation of one form of my elevator. Fig. 2 is a plan, partly in section, on line 2 2 of Figs. 1 and 3. Fig. 3 is a section 011 line 3 3 of Fig. 2. Figs. 4 and 5 are sectional details showing the chain and its buckets and the supporting-wheels. Figs. 6 and 7 are elevations of one of the buckets detached.

Elevators consisting of a slotted frame carrying an endless chain of buckets, mechanism for driving the bucket-chain, mechanism for moving the slotted frame, with its chain of buckets, endwise, and mechanism for tipping it have long been known; and my invention relates to this class of contrivances, and consists, mainly, in mounting the bucket-carrying frame in a tipping frame, the side pieces of which extend across the bucket-carrying frame which moves endwise between these side pieces. This feature of my invention may of course be used with a variety of mechanisms for driving the bucket-chain and for moving the bucket-carrying frame endwise, and it will also be clear that the tipping frame may be controlled by a variety of mechanisms; but other features of my invention relate to improvements in construction by which I produce an elevator which is well adapted for both heavy and light Work, which is durable, easily kept in repair, and readily handled.

In the drawings, A is a frame (composed of two side pieces a and proper cross-pieces a) supported upon the main. shaft B. This frame A receives and guides the frame D by means of guide-blocks a and rollers a A- though, as will be obvious, these blocks and rollers are mere details which may be widely varied, the gist of the matter being that the frame D must be so mounted in the frame A that D may be moved endwise in A, but will tip or tilt as and whenever A is oscillated on shaft B.

be moved endwise, and by which the bucketcarrying frame can be tipped or tilted, as desiredsolidif1es, strengthens, and simplifies this class of contrivances, and also enables all the mechanismsnamel y, those for driving the bucket-chain, for moving the bucketcarrying frame endwise, and for tilt-ing itto to be controlled by the attendant who runs the engine. In fact, elevators and the like with this feature of my invention are practically so vastly superior to all others heretofore known as to constitute a class by themselves.

In the drawings 1 have shown the fra1ne= work F as mounted on wheels f, which rest upon tracks f, this being for convenience in moving the elevator from place to place; but these matters will obviously vary largely with varying circumstances and uses to which the endless chain of buckets is to be put, as will be clear without further explanation.

The engine G supplies power through its shaft g, and the driving-drums g g g g are coupled to shaft 9 at pleasure by means of suitable mechanism, (not shown,) the drawings being necessarily on a very small scale and too well known to need description. The main shaft B is driven by drums g. Drums g are connected with frame D by the chains or ropes 11, passing over pulleys n, and serve to move frame D endwise. Drums g tdrive shaft a, by which frame A. is oscillated. Drums g connect with ropes r by means of which frame F can be moved along tracks f.

The buckets d are connected to rollerchains d, supported by pulleys (Z and these chains d are driven by toothed wheels b on main shaft B.

In operation, for example, taking coal from a collier, the engineer, when the elevator and collier are in proper relation, will first move frame D endwise and upward, (by connecting drums g with shaft 9 for a moment,) then tilt frame D, (by connecting drums with shaft 9,) so that when moved endwise its lower end will enter the hold of the collier regulating this downward endwise motion of frame D by a proper brake forming part of the mechanism (not shown) for connecting drums g with shaft g, and having thus brought the lower portion of the bucket-chain into proper relation with the coal he will drive shaft B by connecting drums g with shaft 9, the motion of shaft B and wheels 1), fast to it, carrying chains (1 and buckets cl about the pulleys (1. As the coal is elevated and discharged through spout (F, the engineer regulates the descent of frame D as may be required.

The main advantages of my improved elevator are that all the mechanisms are readily under the control of the en gineer,tl1atthebucket-carrying frame D is held securely by frame A, through which it moves and by which it is tilted, and that the power is readily applied and so effectively that the waste is much less than in any other contrivance for similar purposes known to me.

\Vhat I claim as my invention is- The improved elevator above described, consisting of a supporting-frame, a main shaft jonrnaled in that frame and having sprocketwheels thereon, a tilting frame carried by the main shaft, a frame movable endwise through the tilting frame, an endless chain of buckets carried by the endwise-movable frame, said chain engaging with said sprocket-wheels, mechanism for driving'main shaft and buckets, mechanism for moving the bucket-carrying frame endwise, and mechanism for controlling the tilting frame, all combined and operating substantially as described.
