TO ALL WHOM IT MAY OONCER-N:

Be it known that I, FREDERICK BERNARD DcERING, of London, England, civil engineer, have invented certain new and useful Improvements in Stands or Frames for Engines for Boring Rock, Cutting Coal, or Working in any other Mineral; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures marked thereon; that is to say- The main objects of my invention are to x the stand or frame securely in the required position while the engine is :1t-work, that is to say, to prevent the carriage turning round the carrying-column as an axis; to provide' ethcient arrangements for enabling the engine, while secured to the parts connected with the carryingcolumn, to be moved into any required position; and to provide arrangements for the supply of water forwashing out the debris, and cooling the boring or cutting-tool or tools while the engine is at work.

Figure 1 is a side elevation of a frame or stand constructed according to my invention.

Figure 2 is a top view of'the framing, and

Figure 3 is a front viewof the back part of the framing.

Figure 4 is a plan ofthe carrying-column and parts connected therewith.

i Figure 5 is a plan of the bow or saddle for holding the engine.

A is a horizontal plate, connecting the sides B B of a carriage-frame. Upon the plate A, a column, C, is mounted, having a series of rings turned thereon. lD is a top plate on the column C, to which plate, at opposite ends, is bolted one end of each of a pair of horizontal steadying or bearing-pieces, E E, to produce asurface for wedging against the roof of adits. The opposite ends of 'these pieces E E are brought together, as shown, and bolted to eachother, and these ends are also bolted to the upper ends of vertical angle-irons F F, bolted 0r secured at bottom to the side carriagefframe B B. Wedges are driven in between the top of the gallery or tunnel and the bearing-pieces E E, which, having three points of support, prevent the carriage turning on a central axis formed by the carrying-column C. A modification, in which there are likewise three points of support for the same purpose, is hereafter fully described with reference to Figure 8. On the column C is a vertical collar, H, formed in a piece with (or it may be clamped or bolted to) a horizontal collar, I. The collar H is raised or lowered on the column C, as required, by turning, by means of a handle, a worm, L, in gear with a Worm-wheel, M, the shaft of which carries a toothed wheel, N, (see dotted lines, iig. 4,) which takes between the rings on the column C.` Carried through the horizontal collar or arm I, is a bar-arm or beam, O, one end of which carries another collar, P. The bar O can be moved on its axis by turning a handle on the shaft of a worm, R, which gears into a wheel, S. T is another bar or beam, carried through the collar P. The outer end of this bar carries a saddle or bow, U, for holding the boring or cutting-engine. To move the bar or beam T forward or backward, it has rings turned thereon, (or it may have a rack for the same purpose,) into which a toothed wheel, provided with a hand-wheel, W, gears. Sometimes I make the bar O to slide in its collar, in `which case the wheel S would be formed with a. feather, to take into a slot in the har. In some cases I dispense with the collar P and bar T. The bow or saddle would then be 'carried by the bar O, which would have rings or a rack, to enable it to be moved backwards and forwards by a wheel, but I prefer the arrangement shown,

as it provides an additional joint. Sometimes, also, I make the bar T free to be turned on its axis, like the bar O. The bow or saddle U is free to turn on a pivot, X, whereby another joint is provided. These joints enable the engine to he moved into any position and inclination required by the work. Y Y are two reservoirs at the back of the carriage-frame, and Z is a tank abovev them, -for supplying them alternately with water, through cocks a a. The reservoirs are tted with outlet-cocks, Zz 6, from which a pipe, 6', is led to the engine, for the purpose of washing out the debris and cooling the boring-tool. The reservoirs are also provided with cocks, a

c, for admitting compressed air to force the water through the' pipe Zz. There are also outlet-cocks, 'cl d, for the escape ofthe compressed air. The frame or stand is mounted en wheels, as shown, to run on rails temporarily laid in the tunnel or gallery.

For sinking vertical shafts, the column marked C, in the figures before referred to, assumes a horizontal position, wedges or steadying-blocks being driven in between a large plate at each end of the column and the side of the'shaft. The column may be formed with longitudinal grooves, to take the place of and answer the same end as the rings before described, a toothed wheel being tted to gear into the grooves, to allow the collar to be turned on the column. This arrangement for sinking vertical shafts is represented in side elevation in Figure 6, and in plan in Figure 7. A A represent the sides of a. shaft. B is the column, which in this case is horizontal, asjust mentioned. C is a plate at each end of the column, between which and the side of the shaft 'wedges or steadying-blocks, D, are driven in. The apparatus is slung from the top of the shaft by chains connected to the frame, as shown. The column B has a longitudinal groove, E, into which a feat-her of a toothed wheel, F, fixed on the collar L, slides. This wheel is in gear with a worm, T, fitted with a crank-handle. By turning the handle the wheel T causes the collar L to turn on the column B. The second collar, M, receives a bar or beam carrying another collar, in which, moreover a bar, O, carrying the saddle or bow, slides, and is free `to turn. The saddle or bow-bar may be formed with rings, into which a pinion, worked by a handle or otherwise, gears, to raise or lower the bar on its collar. If necessary, a worm may be applied to the pinion. In this arrangement for vertical shaft-sinking, I sometimes employ two or more of thc horizontal columns, B, as shown in plan view in fig. 7, and I connect them by a braced frame, which supports a s'taging or platform, as shown, for the men to stand upon.' The collarsI prefer to clamp in the following manner: The tighteningnut is formed with teeth, geared into by a worm, the turning of' which causes the nut to travel on the threaded bolt, and so tighten or clamp theA collar on the bar or arm, as shown in fig. 8. If necessary, the columns are made to travel laterally on the frame, the frame being wedged or otherwise fastened to the side of the shaft.

The modification hereinbeforn referred to, for obtaining threepoint's'of support for the stand or frame, is represented in the side elevationin iig.Y 8. A1 A2 A3 are three columns, one behind theother, and carrying a horizontal beam, B, at the top. v'Ille front column, A1, is formed with rings, and carries the boring-engine; as in the arrangement represented in i'g. 1.4 The columns have screws, C C C, at their upper ends, taking into corresponding nuts in the columns, so that the beam may be raised or lowered, according tothc height of the gallery or tunnel. I drive in wedges between the top of the gallery or tunnel and the horizontal beam B. I t on each screw C a ratchet-wheel, E, into which a pawl, F, ont-he column, takes, so that the screws cannot rotate after having'been adjusted. The ratchet-wheel is formed with a key or feather, to take into a slot in the screw, so as to be free to" move up or down-thereon. When it is required to turn the screw, the pawl is temporarily lifted out of the ratchet. The reservoirs and tank are, in this'nstance, placed between the two columns .A2 A3. `If desired, each, of the columns, A2 A3, may have rings or a rack formed thereon, and carry a boringengine.

What I claim as my invention, and desire to secure by Patent, is-

1. The combination of parts, substantially as herein described and shown, in such manner that tbe'bearingpieces for wedges orother fixing arrangements may have more `than one point of support, and the carriage bo therefore prevented turning round the carrying-column, as shown in the drawings annexed. y

2. The combination of parts, in frames or stands, for boring or cutting-engines, of apivoted saddle or bow, with collars, columns, and arms, with their clamping-arrangements, and moving-gear for allowing the engine to be moved into any required position, substantially as and for the purpose herein described, and shown in \the figures.

3. The combination, with frames or stands for borlng-engines, of reservoirs, and a tank for water, having the necessary inlets and outlets, substantially as and for the purpose herein described, and shown in figs. 1 and 8; 4. The combination of parts of frames or stands, to be employed in sinking vertical shafts, substantially as herein described with reference to figs. 6 and 7.

In witness whereof I, the said FREDERICK BERNARD DRING, have hereunto set my hand, this third day of August, one thousand eight hundred and sixty-seven.
