UNITED VSTATES LEANDER S. WOODBRY, OF CALMET, MIGHGAN.
iSUPPORT FOR ROCKJDRILLS.
SPECIFICATION formi-ng part o Letters Patent No. 323,482, dated August 4, 1885i Application filed March 13, 1835. (No model.)
To all whom tmc/y concern,.-
Be it known that I, LEANDER Swoonnunr, a citizen of the United States, residing at Gala met, in the county of Houghton and State of Michigan, have invented a new and useful lmprovcment in the Column for Supporting a Rock-Drill when it is in operation, set forth in the annexed specification.
My invention relates to that class of columns which are adjustable as to length by means of jack-screws in the foot, by which ihehead ofthe column is pressed firmly against any convenient abutment, -as the hanging wall7 in a mine,or the roof or sides of atunnel.
lts objects are, `first, to increase the durability and decrease the repairs incident to the columns in common use; second, to get different lengths of columnswithout having a completed column for every desired length outside the limit of adjustment by the jackscrews; third, to enable the operator to replace the parts subject to the greatest wear without sending the whole column to the surface. These objects are accomplished in the device illustrated in the accompanying draw ings, in which- Figure l is a vertical section of the lower end of the column and the foot on line a: Fig. 3. Fig. 2 is an end elevation of one of the parts of the foot as on line y y, Fig. 3. Fig. 3 is a horizontal section of the foot and post on line c fc, Fig. 1.
Similar letters refer to similar parts through out the drawings, in which- Y A is the foot, which is made in two pieces, which, being drawn together by the bolts F, Fig. 3, firmly clamps the lower end of the post B. G is a shoulder at the bottom of the foot for the purpose of an abutment for the post B, side of which is turned tapering,the foot being bored to receive the same. The jack-screws D (a portion of only one of which isshown,)and the upper end ol' the part B are common to most rock-drill columns.
All the parts are made of metal, the foot A preferably a steel casting and the nuts c of bronze.
In the rock-drill columns usually used the foot consisted of a block of wood, to the ends of which are bolted the jackscrew nuts, and to the top of which is bolted an iron foot, upon c c are the jack-screw nuts, the outwhich is shrunk the upright or post, which is usually a piece of wrought-iron pipe. This method of construction is the source of constant annoyance and expense for repairs, caused by the wood splitting and the constant loosening of the nuts and iron foot referred to, and of the post where shrunk upon the same; and as in tunneling and mining operations the width and height of the opening is very variable, and often beyond the limit of the jack-screws, sin or more completed colums of variable lengths are required constantly on hand.
By referring now to Figs. 1, 2, and 8, it will be seen how these particular derangements are obviated. The post B is simply a piece of ordinary wrought-iron pipe cut to the desired length, and the usual cap iixed to the upper end. The lower end is inserted into the foot until it strikes the shoulder G, when the four bolts, F, which pass through the ears E are screwed up, clamping the whole together perfectly solid; and any tendency to loosen from any cause can be readily stopped by a still further tightening of the bolts F.
In all devices of this character the jackscrew nuts become quickly worn out on acA count ot' the gritty material about them. In the columns usually used these consisted of heavy castings, the whole of which had to be thrown away when the thread was worn out. To avoid this waste, and to enable the operator of the drill to quickly replace a wornout nut, I bore the ends of the foot, Fig. l, tapering to a standard taper and size, to which the nuts c are always lit-ted. Now, when a nut is worn out in the thread, it is simply driven out and a good one inserted without delay to the drillb I do not confine the application. of the nuts thus described to the particular foot described. They may be fitted to any foot, or even to the castings which constitute the nuts of the old device.
In my invention there is only required, to provide for the varying width and height of opening referred to, different lengths of the post B, each of which is easily adjusted to the same foota consideration of no little importance where the room for operation is contracted.
Having thus fully described my invention inner ends, formed with semicircular seats for the post, with bolts passing through the and the necessity tl'ierefor, what claim as new, and desire to secure by Letters Patent,
1sflanges connecting the parts and clamping the 15 l. In a column for the support of arockpost, and having tapering seats on their outer` drill, a base or foot having tapering seats inends for the .reception of nuts formed taperthe outer ends for the reception of nuts formed ing to iit the seats,with screws passing through tapering to fit the seats, with screws passing the nuts for raising and lowering the said through the nuts for raising and loweringvthe base, with said nuts constructed solid. 2o
said base, with said nuts constructed solid.
2. In a column for the support of a rockdrill, the combination, with the post, of a base formed of two parts having iianges 011 their LEANDER S. WOODBURY. Vitnesses:
