TUNNELING OR MINING MACHINE.
SPECIFICATION forming part of Letters Patent No. 476,836, dated June 14, 1892. Application filed May 3, 1891. Serial No. 383,645- (No model.) Patented in England Ma c 6, 99
To a whom it may concern.-
Be it known that I, REGINALD STANLEY, a subject of the Queen of Great Britain and Ireland, residing at Nuneaton, in the county of VVarWick, England, have invented certain new and useful Improvements in Tunneling or Mining Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to improvements in machines for boring tunnels, such as are used in the excavating of rock, mining coal, &c., and was patented in England March 6, 1890, No. 3,595. As shown, the parts are particularly well adapted for coal-mining.
Figure 1 is a side elevation of a machine embodying myimprovements. Fig. 2 is atop plan View. Fig. 3 is a rear elevation. Fig. 4 is a partial sectional view on the line as a; of Fig. 1. Fig. 5 is a front view of the machine, showing the shield. Fig. 6 is a side view of a modified form of machine. Fig. 7 is a top plan view of the same. Fig. 8 is an end view. Fig. 9 isa section on line :0 00', Fig. 6. Fig. 10 is a section on line y 3 Fig. 6. Fig. 11 is a top view of the devices at the bottom of the machine for preventing it from moving backward. Fig. 12 is a view of the same with the outer bar removed. Fig. 13 is a section on line 2 .2, Fig. 12. Fig. 14 is an edge view of one of the fasteners. Fig. 15 is a front view of the cutting apparatus.
There are some of the features of the present machine which may be used in connection with machines of other sorts. Thus I have illustrated devices for forming an annular cut; but the gearing, shafting, and other power-transmitting devices, as well as those for converting the power, can be used in pro ducing cuts of other sorts.
B B are radial arms carrying forward-projecting cutter-arms B B and secured to a rotating screw-threaded shaft 0, all now well known.
In addition to the annular cutter-arms B I provide other cutter-armsA A, in order to remove part of the core left thereby. The radial arms B B have apertures at intervals in their faces, in which the tongues of the auxiliary cutters are secured by bolts or otherwise. In the drawings but two auxiliary cut tcrarms are shown; but it is obvious that as many as desired may be used, so as to cut away the whole face of the material. As shown, the said arms A A are wider at their front ends and have a tapered nose or proj ection, which cleans away the slack in front of the cutters B It will be seen that these cutter-armsmay be readily detached and secured at any distance from the center of the radial arms B B, as the nature of the material may require, or they may be left off entirely. WVhile I have shown and described these adjustable cutter-arms, I do not herein claim them, as they are shown and described in my pending application, Serial No. 298,690, filed July 7, 1891.
A frame is provided having the vertical standards o a, preferablymade of angle-irons, bottom girts a and top girts a This frame is mounted upon wheels A A of the central longitudinal plan of the machine. At the top it is provided with one or more screw-jacks A, preferably with one at each end. The machine is prevented from yielding backward by means of the hinged brace N, adapted to engage with the floor of the mine.
I provide in the present construction for an additional bracing of the machine, this being accomplished by wedge-like bars V. These can be driven by a hammer or similar instrument tightly into the floor and roof and be then clamped in place by means of lockingwedges V They are supported between one of the longitudinal bottom frame-bars a and a supplemental outside bar held thereto by bolts w. The catch-bars V are pointed or chisel'shaped, as shown in Fig. 12, so as to readily engage with the floor or roof, and the clamp V binds the part V tightly between two blocks or plates 10 w, held in place by the said contiguous bolts 10 to. As a further bracing of the machine, as it is desirable to keep the cable by which power is applied quite taut, I provide arms or sprags X X, hinged to a sleeve Y on the screw-shaft of the machine. The sprags are forced apart into holes cut in the tunnel by means of telescope-screws X X, swiveled to the said sprags and carrying wheels X by means of which the said screws are elongated and contracted. The sleeve Y slides loosely on the anism.
central shaft and when the machine is making a cut abuts against the rear of the machine. Through the sleeve from side to side is an aperture or slot Y, into which may be slid a plate Y which is shown in Fig. 1 as hanging by a chain to the sleeve. When a cut has been made and the shaft has been moved forward its lengththatis to say, until the end of the shaft has j nst passed the slot Y in the sleeve-the plate Y is slid into the said slot and prevents the shaft from being pushed back in the heading or tunnel while the machine is being advanced.
As shown in Fig. 5, hinged shields Z may be used to keep the rock and dirt from falling on the machine and operatives. These shields may be made of sheet metal and are forced out against the roof of the tunnel by side stays as m, the points of which penetrate through holes in the shields and shoulder against them. These shields not only protect the machine, but also when the sides of the heading are broken and irregular, as is sometimes the case, through the practically uniform pressure they exert the machine is kept upright and steady.
Lateral braces and guides for the central part of the machine are shown at 00 x these comprising pivoted vertical frames having bottom bars a and top bars a, hinged to the main frame, and holding-links :0 for locking the swinging parts in place. At the outer ends of these frames there are rollers 90 arranged to bear against the vertical walls of the tunnel, so that the machine can be held firmly upright and at the same time be moved forward or backward without serious resistance.
Additional braces to keep the machine upright may be used. In Fig. 3 they are shown as being comprised of the rigid grooved plates y y, sliding parts y y, fitting in said grooves, and ribbed wheels zfiyfi, mounted on said sliding parts, the said wheels bearing against the side walls of the heading or tunnel. The wheels are adjusted in relation to the machine by means of screws 31 which are provided with right and left hand threads.
Power is applied to the machine as follows: Z is a rope or cable, hich extends outward along the tunnel or heading to any point suitable i'or applying motion and power. It is passed several times around a grooved wheel W and extends thence to the point whence the power is applied. The wheel \V is mounted on one end of a shaft F, which is mounted in suitable bearings in the sides of the machine and has on the other end a bevel-wheel D which actuates both the cutter-driving and the advancing mechanism.
I will first describe the cutter-driving mech- On one end of a shaft E, mounted in bearings at the side of the machine, is a bevelwheel D meshing with the said bevel-wheel D and 011 the other end is loosely mounted a pinion D, which meshes with a wheel D, having a spline or feather which engages with a groove in central shaft 0. At D is a clutch mechanism for connecting and disconnecting the pinion D to the shaft E. WVhen a out has been made, the frame is advanced as follows: The pin 0 is withdrawn from wheel E and the supporting-plate, thereby unloosing said wheel from its stationary position. Then the nut-wheel, being thereby unlooscd, is driven by a pinion E rigid on one end of a shaft E which carries at its other end a pinion E. Meshing with the pinion and actuating it is a wheel E which is loose on a shaft E, mounted on the side of the machine and carrying on one end a bevel-wheel E which is driven by the bevel-wheel D on the powershaft. A clutch mechanism is shown at D for connecting and disconnecting wheel E to and from shaft E. The clutches D D are shifted by levers F F respectively, said levers being pivoted to the side bar a of the machine and also to the bar F which is moved forward and backward by means of L-shaped handles F F It will be seen that by the same movement of bar F wheel D and shaft E are connected and wheel E and shaft E are disconnected, and vice versa, when the bar F is moved backward.
\Vhen the machine has been secured in the tunnel by means of the braces and stays, the nut-wheel E is locked relatively to the frame by inserting pin 0' through an aperture in wheel E into the supporting cross-plate, and the clutch-levers are moved forward, and power is applied to the wheel D in the way just described, whereupon the central shaft U is caused to rotate and advance. After a cut has been made the nut-wheel E isreleased, (the plate Y being in place in the slot Y,) power is applied to the wheel E and the frame is advanced.
In Figs. 6 to 10 a modified form of machine is shown possessing the same general principles of construction and arrangement. In this construction the machine is provided with a jack-screw A directly over the center and adapted to bear downward through a frame secured to the top of the machine. Referring to Fig. 6,it will be seen that the cable Z first passes under a guide-pulley V, then one or more times around a grooved Wheel WV, and thence again under the wheelVand back or out to the source of power. The wheel V is supported in a frame, which can be vertically adjusted, so as to regulate the tension of the cable immediately adjacent to the power-wheel W. The latter is secured to a shaft F, which, by means of a pinion D rotates a wheel D and a shaft D which carries it. The shaft D has a bevel-wheel D whiehengages with a second bevel-Wheel D upon shaft E. The latter has a pinion D engaging with the main wheel D, by which the cutter-shaft O is rotated. Shaft C is grooved, and with it engages a spline or feather in wheel D. It will be readily seen that the gearing thus arranged is compact and simple.
It Will be understood that a frame-advancing mechanism may be used on this machine, although I have shown only the gearing necessary for driving the cutters. When a out has been made, the whole machine may be moved forward by hand-power; but I have found it often preferable to use a mechanism, as shown in Fig. 1.
There are many circumstances under which it is desirable to use power of the sort herein provided for, as there are many collieries where it is either not practicable or is too expensive to provide steam-power or compressed air, and yet wherein use can be made of horses in such way as to provide the power necessary for operating the cutting-machine.
I am aware that drills have been used in which vertically sliding loosely supported stays have been utilized for fastening purposes and that there have been numerous Ways devised for locking the same; but in such drills the stays are necessarily the vertical supports, and when they are removed the machine cannot be used. In some cases these stays have been driven into the roof and floor of the heading, and nuts, handwheels, or set-screws have been used to lock them, and in other cases locks, each consisting of a lever and dog and rack, have been used, and 1 do not wish to be understood as claiming such devices. My stays differ greatly from these. In the first place, the machine is supported independently of the said stays, and, secondly, only one may be used or a dozen may be driven in if one is not enough to stand 'the strain. The stay is driven with a hammer as far into the floor or roof as de: sired, and then with a few blows of the hammer the Wedge is inserted, tightly clamping the stays in place.
I do not herein claim any of the subjects matter set forth in the claims of my other applications, Serial N 0. 347,238, filed April 9, 1800; Serial No. 364,060, filed September 5, 1890; Serial No. 389,690, filed July 7, 1891, and Serial Nos. 414,708 and il4,709, filed J anuary 22, 1892, wherein are shown machines of this general class.
