T'
The nature of my invention will bebest understood by rreference to the accompanyingfdratvings, in which-l have shown a pre- -ferred 4embodiment thereof, and which will nowl lie-described, itl being premised7 however,V thatvarius changesan be inade iiithe construction, arrangement and combination of the several parts'without.departing from the spiritand scope of myinvention as! de- `fined in ythe app'endedeclaims. i

-The valve 11 is;automatically actuated h v any suitablev means,l suchl :its the tivo'armed lever '26,"one'ar'm owliich is connected s to the valveA` stemt'I 27' arid the' other amof lwhielris connected to 'a tappet rod 2S." This tappet rod extends through the nut"meni'ber "15 andv terminatesV atitsziorWard' end iiifthc head: 29. v"Ther'od .'18 is preferably 'provided [With a longitudinal `passage 3C) entend-ing y longitudinally therethrough, .theV firont Avend off this 'passage vbeing arranged' toA 'crnmuhicate with -t-lie" interior of" the hollowjdriiling tool. 20, and its rear 'endlbeing in crnmunicatin through va. port 31 "inthe zcap i825? l'with ai pipe '33 having' aliexible p'ortionti ivhic'h isconnected vviththeneXhaust 37 ofshthe valve The operation of the drill will be readily understood. Actuating fluid being admitted to the rear end of the cylinder 9, the piston 13 is moved forwardly, carrying with it the sleeve 14. This, through the nut 15, rotates the rod 18 and drilling tool 20, and at the same time advances said tool to the work. When the piston reaches the limit of its forward stroke, the nut 15 engages with the head 29 of the tappet rod 28, thereby actuating the lever 26 to reverse the valve 11. Upon the back stroke of the piston, the sleeve 14 and nut 15 are retracted to an extent equal to the full travel of the piston 13; butl the rod' 18 and the drilling tool Q0 have only a limited retraction owing to the fact that as soon as the clutch balls 21 engage with the tapered part 25 of the sleeve 24,
` said rod 18 will be clamped sufficiently tight to prevent any further backward movement, although still permitting it to be rotated by the backward movement of the nut 15.
The exhaust from the cylinder is caused to be discharged through the drill for the purpose of blowing out the clay as it is cut by the drill.
The drill is provided with a suspension system which consists of a flexible cord or cable` 38 attached thereto, which extends upwardly and over suitable guiding pulleys 39, and thence downwardly to a winding shaft 40 (see Fig. 2). The suspension sysvtem also comprises the two links 41 which are connected to the central portion of the drill casing at their lower ends, and at their upper ends are pivoted to a suitable bracket 42 secured to the bustle pipe 4.
43 designates a hook which is pivoted to the drill casing and which, when the drill is in operative position, as shown in full lines in Figure 1, is adapted to be engaged with the shaft 7a of the dogs 7, thereby holding the drill in proper relation to the tapping hole 6.
After the tapping operation is completed, the cord or cable 38 is wound on the shaft 40, thereby swinging the drill upwardly until it assumes the suspended position shown in full lines in Figure 2 and in dotted lines in Figure 1. In this position, it is suiiiciently elevated to be entirely out of the way of other operations around the base of the furnace.
My invention provides very simple and desirable apparatus for the purpose for which it is intended. It can be readily moved into'position and set in operation, after which it continues to operate until the tapping hole is drilled out, without necessil'tating the presence of workmen in the immediate vicinity of the tapping hole. Vhen the tapping out operation is finished, the
.device can be readily moved to its inoperative position, where it remains until it is again desired to use it.
