Application filed October 14,1890, Serial No. 368,133. (No model.)

To all whom it may concern:

Be it known, that I, Milton T. Rose, of Orland, in the county of Steuben and State of Indiana, have invented certain new and useful 5 Improvements in Coal or Grain Elevators; andldohercbydeclarethefollowingtobeafnll, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, referio encebeinghad to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in grain or coal elevators; and it consists in the arrangement and combination of parts, 15 which will be more fully described hereinafter.

The objects of my invention are to provide an elevator apparatus for raising the car or hopper in which the article to be elevated is 20 placed, so that the article can be emptied in bulk directly into the top of the bin; to use the same team which hauled the article to the elevator to raise it to the desired elevation; to attach to the operating rope or chain an 25 automatically-acting device for releasing the teain as soon as the car is raised to the desired height, and to connect the catches which prevent the descent of the elevator-car to the lever- which controls its descent, so 30 that the catches will be thrown out of gear only when the elevator-car is descending.

Figures 1 and 2 are side elevations taken from opposite sides of the elevator apparatus. Fig. 3 is a plan view. Fig. 4 is a side eleva35 tion taken at right angles to Figs. 1 and 2. Fig. 5 is a vertical section taken through the elevator. Fig. 6 is an enlarged view of the detaching apparatus. Fig. 7 is a detached view of the detaching mechanism. Fig. 8 is 40 detached side elevation of the operatin?drum.

A represents the platform or frame-work upon which the loaded wagon is drawn, and B the four vertical uprights, which serve as 45 guides for the elevator car or cage C in its vertical movements.

Journaled in the frame-work is the operating-shaft D, to which the operating-drum E is secured, and to which drum the rope or 50 chain F is fastened at one end. As the elevator car or cage G descends from its own weight this rope or chain is wound around the drum, and then when the elevator car or cage is to be raised the same team which drew the load to the elevator, car or cage is 55 attached to the rope F by passing the rope J around the rear axle of the wagon G, coupling the link on end of rope J to angular catch I. Leaving the elevator, the team draws the rope F, operating the drum E. 60

In order to automatically detach the team from the rope or chain F as soon as the elevator car or cage C has reached the desired height, there is secured to the outer end of the rope or chain F a rod II, and to the outer end 65 of this rod is loosely connected the angular catch I and the rope J. To the free end of the rope J is secured a link or eye 2, which, after the rope J has been passed around the axle of the vehicle G, is made to catch over 70 the angular catch I.

In order to regulate the exact distance that the team shall move, a rope, wire, or chain K is used, and this rope, wire, or chain is fastened to the platform A at one end and has its 75 .outer free end provided with a knot, ball, or stop L of any kind, and this outer end of the rope is passed through a loop in a rod M, which has its other end attached to a wire loop N, fastened to a sliding block 0, which is placed 80 upon the rod II. This block 0 is rigidly secured to tlie outer end of a spiral spring P, which spring has its inner end fastened to the inner end of the rod II. The spring keeps the block 0 forced outward upon the rod II 85 until the length of the rope or chain K is reached, and then this rope or chain exerts a backward pull through the rod connected to its outer end upon the block, and thus draws the block back upon the rod II against the 90 tension of the spring, so as to cause the block to release the rear end of the angular catch I and allow it to spring outward, as shown by dotted lines. When the ring or loop 2 slips off the triangular catch, it releases the vehi- 95 ole G. The rear end of the angular catch I is made to catch in a recess in the outer end of the block, and hence when this block is drawn back the end of the angular lever is released.

In attaching the rope F to the drum E there 100 is a spring cZ, to which the lower end of the rope F is attached to enable the revolution to

449,495 cease just at the right time, and yet give the chain a little more forward motion to insure the automatic detachment.

Upon the shaft D are secured the sprocket5 wheel Q and spur - wheel R. Around the sprocket-wheel Q is passed a sprocket-chain S, which extends across between the uprights B and around a second sprocket-wheel T upon the shaft U for the purpose of conveying the io motion of the operating-shaft Γ) to the shaft

U. The spur-wheel R meshes with a similar wheel V upon the shaft W, and upon this shaft W is placed a sprocket-wheel X.

Around the two sprocket-wheels Ν' X pass 15 the two sprocket-chains Y, which also pass over the sprocket-wheels Z Z' upon the shafts A' A², journaled upon the upper ends of the . uprights B, both ends of the chains being fastened to the elevator car or cage C, which 20 moves in suitable grooves prepared for it between the uprights. On the outside of the uprightsB and attached to the sprocket-chains Y are two weights a, one on each side of the elevator, of suitable weight to prevent the ele25 vator car or cage C from dropping too rapidly.

The elevator car or cage C is provided with guides B' upon its top, so that the car or hopper b upon it will be guided in its movements 30 back and forth.

In order to regulate the descent of the car, there is secured to one of the uprights B a rack C', and secured to the elevator car or cage is a gear-wheel D', which meshes with a pinion 35 E' upon the shaft of the friction-wheel F'. Pivoted to the elevator-car is a friction-lever G', which by being raised forcibly in contact with the wheel F' regulates the speed at which the elevator-car shall descend, and in descend40 ing operates the shaft D in such a manner as to cause the chain or rope F to be wound upon the drum. Secured to the outer side of each of the ends of the elevator car or cage C are the two catches II', which are long enough at 45 their inner ends to overlap each other, and which at their outer ends catch in recesses or notches made in the inner sides of the uprights B, for the purpose of checking the descent of the elevator car or cage. Projecting 50 across and through the elevator car or cage is a rock-shaft I', which has its ends turned at an angle, and which bent ends catch under the catches II', for the purpose of raising them at their inner ends and withdrawing 55 their shorter pointed ends from the recesses or notches in the inner sides of the uprights. In order to operate this shaft I', so as to cause it to detach the catch II' at just the proper time there is secured to this shaft I' an arm 60 or lever J', and this arm or lever J' is connected to the lever G' by means of a cord, wire, or chain 4. When the lever G' is forced against the wheel F', the arm or lever J' causes the shaft I' to partially revolve and 65 thus raise the catches II', so as to leave the elevator-car free to descend. Should the elevator-car at any time begin to descend of its own gravity before it is desired, the catches II' would arrest its descent, and thus prevent any possibility of the car falling. The inner 70 ends of the catches are sufficiently heavy to force the outer pointed ends against the uprights; and hence the greater the pressure upon the car the stronger the hold the catches take upon the uprights. The elevator-car is 75 raised to the height of the plane of the top of the bins into which the coal, grain, or other article is to be emptied. The car or hopper is run off from the elevator-platform and to a position over the bins in which the contents 80 of the car or hopper is to be deposited. After the deposit the car is run back upon the elevator-platform and descends with it to the platform A.

By means of the construction here shown 85 it will be seen that the team which drew the load is used to elevate it upon the elevatorplatform.
