SPECIFICATION forming part 0f Letters Patent N0. 604,330, dated May 17, 1898. Application filed October 18, 189'7.V Serial No. 655,575. (No model.)
-To all whom t may concern: y
Beit known that I, GEORGE F. KIBLING, a citizen of the United States of America, re-` siding at Hanover, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvements in Mining Apparatus; and I d0 hereby declare the following to be a full, clear, and exact description of the 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, and to letters of reference marked thereon,^which form a part of this specification.
This invention relates to improvements in tunneling or mining apparatus; and the ob` ject in view is to provide an effective means for excavating in frozen soil; and it consists in the means employed forthawing the soil in front of the apparatus, so that it will fall upon a suitable conveyer and be carried thereby to a car.
In carrying out my invention I make use of a movable platform, preferably mounted on wheels, said platform being provided with a compartment or chamber for the operators who work in the tunnel, said compartment being provided with an air-supply pipe which leads into the chamber for the purpose of supplying air to the operators; also with for-A ward projecting tubes through which steam can be forced upon the soil to thaw the same in advance of the excavating apparatus.'
The invention further consists in the Vconstruction, combination, and organization' of the parts, whereby means are provided for thawing out the soil, conveying the same to a separator and from thence to a car, and
' shielding the operators while at work, as wellt as providing a signaling means for the operators within the compartment and means whereby they can move the apparatus backward or forward upon its tracks.
In the accompanying drawings, Figure l'is a side elevation showing generally the embodiment of my invention. Fig. 2 is a plan view, and Fig. 3 is a detail view, of the end of the pipe.
The apparatus which I will now proceed to describe is designed, primarily, for mining in frozen soil, and it is designed to provide means whereby mining may be carried on during the winter season by tunneling into the soil which is held compact by reason of its being frozen, owing to the intense cold in such regions, Alaska andthe British possessions adjacent thereto being an example of the region in which this apparatus is adapted for use.
`A-` refers to a suitably-constructed platform or frame having supporting wheels or rollers a, the wheels or rollers being adapted to engage with tracks laid on a line with the floor ofthe tunnel. The side bars of the platform extend considerably'in front of the forward rollers or wheels and carry a shaft a', over which passes an endless conveyer B, which hasiat suitable intervals buckets or excavators b.' This conveyer B is guided by rollers b and a shaft b2, so that the rear part can be upwardly'` inclined, being maintained in an elevated position by a roller or drum c,which is driven by a belt or sprocket-chain, which extends therefrom to the driving-wheel of an engine D, mounted on the platform.
E refers to a compartment or chamber of sufficient size to accommodate two or more workmen, and this chamber is a rigid structure mounted on the platform and made as near air-tight as practicable and is provided y at its front and rear with windows c and doors eff, The front wall E of the chamber has secured thereto side or laterally projecting wings, the lower portions of which curve inwardly, so that the gravel or soil may be guided thereby toward the conveyer, which vis located between the side bars of the platform. l
` Through the iioor of the chamber extends a shaft F, having at its upper end a handwheel, the lower end of said shaft being geared to the forward roller of the platform, so that by turning the hand-wheel the platform and parts carried thereby can be moved in either direction. L .Through the front wall of the chamber extends a bar G, the same engaging with auniversal coupling or jointfso that it can be moved from within the chamber, where it is provided with a suitable handle, and the rod G is hollow and provided near its end with a plurality of perforations, said end being preferably pointed, so that it may be used in breaking down the soil or forced into the soil,
so as to be held thereby while it is thawed IOO `v,/ut by a jet of steam or heated air, which passes through the rod or tube G.
In mining, at a suitable distance from the tunnel which itis desired to excavate is locateda steam-boiler and an air-pump of any suitable/type, and the air is forced into the tunnelthrough a pipe I, which has a flexible section I', connected to a pipe I2, which enters the chamber E, and said chamber is also provided with an air-outlet pipe I3, the end proj ecting forward of the compartment or chamber. The ends of the pipe I2 and I3 are provided with suitable valves and cut-offs, which may be operated within the chamber.
S and S' refer to steam-pipes which extend from the boiler hereinbefore referred to, but not shown, to the chamber or casing, said steam-pipes having intermediate flexible sections the same as the air-pipe, and the pipe S has a T-head from which extend pipes, one passing through the casing and being provided with a whistle w, the other branch having a hose or flexible connection 71 which is attached to the tube G. Suitable cocks or cut-offs are provided within the casing. The whistle provides means for signaling from the chamber to the boiler or power house. The steam-pipe S extends within the chamber, where it is provided with a valve or cut-o s, and, again, through said chamber, Where it is connected to an engine, said engine driving the conveyerB, hereinbefore referred to. The exhaust from the engine is carried, by means of a pipe S2, to a point beyond the conveyer, where a separator is located, said separator preferably comprising a drum or cylinder which is perforated and is rotated in any suitable manner. The drum is inclined, and the ore is delivered into the higher end from the conveyer. Beneath the drum is a frame or box which is supported by springs 7c, and said frame has a screen and below the screen -a series of riffle-plates, and the pan or box having the riffle-plates is adapted to contain vQuicksilver, which is kept in a fluid condition or from freezing by the exhaust-steam from the engine D. The box or pan forming a part of the separator is agitated by a cam-wlieelt on a shaft which is driven from the drum c.
The ore carried by the conveyer will be deposited into the revolving drum and the smaller particles will pass through the drum upon the screen or sieve below the liner particles, falling into the box containing the rifile-plates. The larger particles of the ore which do not pass through the perforations in the drum or screen below will be deposited in a car which can be positioned on the track beneath the lower end of the separator. If desirable, the ore can be deposited directly into a car.
In the regions where this device is intended to be used the soil or earth bearing gold ore is principally of a gravelly nature, which is frozen, so that it can only be worked during the summer season; but with this apparatus the soil can be excavated and carried to such buildings where it can be worked during the entire year.
I am aware that prior to my invention it has been proposed to make tunnels or shafts by freezing artificially the earth in front of a wall, so that the earth can be prevented from caving in during the process of excavation. In the present instance we are met with a condition of extreme cold,which, acting upon the earth, forms it into a rock-like mass, and the thawing of the same by the application of steam will bring the soil into such condition that it may be removed by an excavator, substantially the only manual labor that is performed being to guide the steam-jets so as to thaw the soil where desired. Then the tunnel has been excavated to such a distance that it is necessary to lay further tracks for the platform, the structure may be moved rearward and the tracks then laid, for it will be noted that the forward end of the excavator or conveyer is considerably in advance of the forward or supporting wheels.
Many changes in the form of the apparatus may be made without departing from the spirit of my invention.
Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is
