HOISTING AND DUMPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 711,049, dated October 14, 1902. Application filed February 20,1901. Serial No. 48,135. (Nomodeh) To all whom it 777/661] concern.-

Be it known that I, CARL JAoKsoN, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of 0010- rado, have invented certain new and useful Improvements in Hoisting and Dumping Devices; and I do declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

My invention relates to a class of machinery designed for hoisting and dumping ore, rock, or any other substance. It is especially valuable when applied to a prospect where the development of the property is not sufficiently advanced to warrant the expenditure necessary for the erection of an extensive hoisting plant. It is also especially valuable for placer-mining, where it is desired to sink to bed-rock, as one man can hoist the material and dump it into the sluice-box without any assistance, thus facilitating and reducing the cost and expense of placer-mining.

The objects of my invention are to provide a hoisting and dumping device that will be easily operated and adapted to be used over a shaft or place of excavating where it is customary to use an ordinary Windlass and a bucket or a steam or electric hoist, as any power-hoist can be used in connection with my new device. It is so constructed that it can be readily attached to any power-hoist; also, to provide for dumping either into the car or at an extended distance from the shaft over the dump. It is simple and durable in its construction and can be manufactured at a very reasonable cost.

The manner of constructing and applying my new hoisting and dumping device is fully illustrated in the accompanying drawings, in which Figure 1 is a perspective elevation of my invention, showing the bucket as dumping into an ordinary ore-car. Fig. 2 is a side elevation showing the bucket hoisted ready to be placed upon the truck device. Fig. 3 is a View of the device at right angle to that in Fig. 2. Fig. 4. is a cross-section, on an enlarged scale, of the track with an end view of the truck. Fig. 5 is a view of the weight.

A represents an ordinary platform which is built around the collar of the shaft; To this platform A is secured four upright oppositelyinclined posts, (designated by A, A A and A To these posts, near the top, is secured an iron framework, (indicated by A Two of the posts, those indicated by A and A extend upward through the iron frame A and have secured to the top thereof a cap or frame A, which is provided with lugs A and A The other posts A and A terminate at the frame A and to complete the foundation or support for the cap or frame A are provided the posts A and A which have the lower ends secured into the iron frame A and the upper ends into the cap or frame A. To this cap or frame A is attached, by means of a journal A, running through the lugs A and A a sheave B, over which is passed the hoisting rope or cable, (designated by C.) An inclined T-rail (indicated by D) is provided and attached to the iron frame A A supporting-stay D is attached to the outer end of the ,T-rail and also attached to the lugs on the cap or frame A. The T-rail D can be of a length adapted to be supported by the stay D, or it can be of any desired length and have provided suitable supporting devices, (indicated by E in Fig. 1 of the drawings.) By this means of ex tending the T-rail the bucket can be conveyed any convenient distance from the shaft and the contents thereof dumped. This provision is of great utility at times when taking ore from theshaft, as the ore can be dumped into the car and the gang-rock or refuse run out to the dump by means of the extended inclined rail.

F represents an ordinary ore-bucket provided with a bail F, to which is attached the rope or cable C. When the bucket is hoisted from the shaft and comes in the position shown in Fig. 2 of the drawings, the hail of same is grasped by the large hook contrivance (designated by'G) which is appended to the truck device H. This truck device is provided with two rollers or wheels II and H which have suitable flanges designed to keep the truck device from twisting, which would cause friction and prevent it from running freely and with ease upon the T-rail. A sheave (designated by I) is provided and attached to the truck device H, as illustrated in Fig. 4 of the drawings. Another sheave-(indicated by J in Fig. l of the drawings) is attached to the iron frame A K represents a rope or cable, one end of which is suspended into the shaft and provided with a weight. The other end passes upward through the sheaveJand outward under the T-rail to the sheave I, which is attached to the truck device H, is then passed downward through said sheave, and the end provided with a hook, (designated by L.) When the bucket is hoisted to the position shown in Figs. 1 and 2 of the drawings, this hook L, which is attached to the said rope or cable, (designated by K,) is hooked into the ring or eye M, attached to the bottom of the bucket, and after the bucket has been hung upon the large hook G and the hoisting rope or cable 0 slackened the bucket will roll outward on the T-rail, which is inclined enough to cause it by its gravity to move down on the rail, and when it reaches the desired point adjacent to the ore-car or to the sluice-box or any point where dumping is desired the simple operation of pulling upon the rope (represented by K) to which is attached the weight dumps the bucket, as fully illustrated in Fig. 1 of the drawings. Y

It is now obvious that when my new hoisting and dumping device has been constructed according to the accompanying illustrations and the foregoing description the successful operation and utility of the same will be as follows: The bucket is hoisted from the shaft by any practical means, (either a geared Windlass, as shown in the drawings, a whim, or by any power-hoist,) and when it reaches the position shown in Figs. 2 and 3 of the drawings it is placed upon the large hook contrivance designated by G, which is appended in recessed or depressed portion H of the truck H, provided in the truck device H, which rolls upon the flanges of the T-rail. The outer end of the T-rail is lowered enough to form a proper incline, down which the bucket will roll when placed upon the truck device and the hoisting-rope 0 released from the drum of the hoist. YVhen the bucket has reached the point Where it is desired to dump, the rope' or cable designated by K provides means for dumping it, as fully illustrated in Fig. l of the drawings. The weight that is provided and appended on the end of the rope or cable K is simply to keep said rope tightened and-take up the slack as the bucket is passed backward and forward. After the bucket has been dumped the hoisting rope or cable C is again wound around the drum of the hoist, which draws the bucket up the incline of the T-rail to the position shown in Figs. 2 and 3, where it is released from the large hook G. The hook L, which is attached to the dumping rope or cable K, is released from the ring or eye provided in the bottom of the bucket, when it is again ready to be let down into the shaft or place of excavation.

It is now manifest that the utility of the extension-rail, in connection with supports similar to the one designated by E in Fig. 1 of the drawings, will in many cases prove great, as by this means the bucket can be conveyed a convenient distance from the shaft or place ofexcavation and can be readilydumped by one man, who need not leave the means of hoisting, thus enabling him to have charge of the hoisting machinery and also do the dumping.

I do not confine myself to any one mode of constructing my new device nor to any particular means of applying hoistingpower to the same, but desire to construct it in various sizes, in any manner, and of such material and apply Whatever hoisting power that may prove most efficient and best adapted to the uses and purposes for which it is designed without materially deviating from the principle involved and the construction outlined and claimed. I also wish to construct it either with a short T-rail, supported only by means of its attachments to the frame and the stay-rod, or lengthen the rail and support it by means of a suitable device. (Manii'estly illustrated in Fig. l of the drawings.)

Having thus described the nature and ob jects of my invention, with the manner of constructing, applying, and operating same, what I claim as new, and desire to secure by Letters Patent, is
