To all whom t may concern:

Be it known that We, VICTOR .IETLEY and GUs'rAvE Jnrnnqsubjects of the Queen of Great Britain, residing at No. 8 North Audley Street, London, in the county of Middlesex, England, have invented a new and useful Combined Multiple Boring or Drilling Machine, with Means for Driving Rods, Bars,

or Tubes into the IToles Drilled, (for which ro Letters Patent have been obtained in the following countries, to wit: Great Britain, No. 20,698, dated October 29, 1891; France, No. 250,603, dated September 28, 1895; Belgium, No. 117,659, dated September 28, 1895; Germany, No. 90,283, dated October l1, 1895; Hungary, No. 5,810, dated December 9, 1895; Canada, No. 52,951, dated July 18, 1896, and Austria, No. 20,651, dated October 21, 1896,) of which the following is a specification. 2o Our invention relates toLmaehines for drilling or boring holes, particularly long holes, and for driving rods, tubes, or bars through such holes when bored, in which the operating parts are automatically controlled.

In the accompanying drawings, Figure l represents the work-holder in plan. Fig. 2 is a plan of the under side of the work-holder. Fig. 3 is a cross-section of the work-holder on the line a a., Fig. 5. Fig. @L is a cross-section of the work-holder on the line b o, Fig.

Fig. 13 is a detail view, in part section, on the center line of one of the rams or rod-drivers; and Fig. 1B:L shows a roddriver in plan and guide-tube therefor in section. Fig. la is a detail view in plan of part of the gear for closing and opening the mouths of the guide-tubes in which the rods or bars are guided before and during their 5o entrance into the holes drilled, and Fig. 15

is a sectional elevation thereof.

The work-holder F may be of any suitable material or construction, provided there are means for clamping the work at the side or sides and the bottom or top, or both-such as shown, for instance, in Figs. 1 to 7 as the elamping-bars or platens f and clampingscrews f2, having capstan or other suitable heads with a large bearing-surface. The 6o work is prevented from bulging, on being clamped or drilled, by cross-bearers f3, held in position on the sides of the frame by capstanwscrews passing through suitable holes, said bearers resting on longitudinal strips f4, placed preferably across the joints, or by other similar or suitable means. In the bottom of the work-holder is a groove f5 to fit on a guide-rail, upon which the work-holder may be moved from place to place. Holes f 7o are provided in the top of the work-holder and holes f7 in the bottom clamping-bar f to enable the drills to pass through.

The blocks A, of wood or any desirable material or materials, may be of any length, provided such length be a multiple of the pitch of the holes to be drilled, and the said blocks may be of similar or varying breadth, but of equal depth, and are placed in the worlz-holder in such a manner as to break 8o joint in alternate rows or series of rows and are clamped tight longitudinally transversely and from the top, so that on the rods, bars, or tubes B being inserted in the holesdrilled the blocks become a homogeneous slab.

Referring to Figs. 8 to 15, the machine is provided with a frame E, on which is mounted a platform F2, Fig. 10, Sheet 3, having a hori- Zontal rail E. rlhe work-holder F, containing the blocks A, is moved forward along the 9o horizontal rail E' under the drills 110 for the purpose of drilling the holes and may conveniently be fixed above by setserews E12 on bent arms made in one with or fixed to the frame E. Sliding and suitably guided ina part of the frame E is a number of guide and feed screws which carry the spindles, to which are fixed the drills or other tools. The drilling and rod-driving operations take place in line with and parallel to each other-that is to say, the right-hand side of the machine is devoted to drilling, while the left-hand side is for driving the aforesaid rods B. r1`here are two pulleys G20 and G2T loose on the main driving-shaft G21, one of which is driven in one direction, while the other is, for instance, by a crossed belt driven in the other direction. Midway between the two loose pulleys G20 and G21is placed a double friction-clutch (indicated by the letter 1) of any suitable construction, whieh is operated by means of a forked lever 12, `pivoted as shown, the lower part of which takes ,in between a fork of a double-arm ed lever 118 at the back of the frame E. This lever 11S (also shown in plan in Fig. 82) is pivoted in the middle to the under side of the frame E. This lever 118 is by its fork in front connectedv to a pin on a striking-bar.

G12, supported and capable of sliding in bearings on the frame E and having a handle G12. On the main shaft G21 are mounted miterwheels 12, which gear with miterwheels 10. On each of the saine spindles which carry the initer-wheels 16 is mounted a spur-wheel 18, each -of which gears with two pinions 10. These pinions 12 are each keyed to the guide or steadying tubes 112, as shown in Figs. 8, 9, lO, and ll. 1n order to cause the drills 111 to revolve with the guide-tubes 112, the latter are provided with longitudinal feather-ways, and the drills have feathers 110, Fig. ll. The guidetubes 112, as to their lower ends, revolve in bearings in the frame E. The upper ends of the guide-tubes revolve inside guide and feed screws G0, which are supported in the frame E. These feed-screws G0 are hollow in order to pass down outside of the guide-tubes 112, and their upper ends are closed by flanges G, which carry the upper ends of the drill-spindles 110 and are provided, if desired, with ballbearings, as shown, which work on the top side of the flanges on the top of the drillspindles 110. The drill-spindles 110 are screwed or otherwise securely fastened to the drills 111. The feed-screws G6 do not revolve by reason of their having longitudinal featherways into which take feathers G20, Fig. ll.

The feed-screws GG are screwed up and down by motion being applied in-one direction or the other to the worm-wheels G2, which are screwed internally, and thus form nuts. These worm-wheels are prevented from moving up or down by the frame E. The wormwheels G7 are driven by worms G2, mounted on the shaft G23, mounted in brackets G0 on the frame E. The shaft G23 is driven by the pulley G20 with a strap from the pulley G10 on the main shaft G21.

1n Fig. 8 is shown a second set of pulleys G20 and G20 to give a higher rate of speed on the return stroke. The pulleys G12 and G29 are connected to the main shaft by the friction-gearing, (indicated by the letter 1,) which is operated from the striking-l')ar G12 in the same manner and at the saine time as has already been described with referenee to the pulleys G20 and G2T and the main shaft G21, 'so that when the main shaft is stopped or the direction of its motion changed, as described, the shaft G22 is similarly affected. The rods B aforesaid are inserted in the slotted guidetubes K2, the lower ends of which are keyed or otherwise secured to the frame E, while the upper ends are inserted in the hollow screws G0, which are supported in the frame E. On the lower ends of the screws G0 are screwed caps K, to which are secured the rams K by means of the webs which project through the slots in the tubes K2. (See detail view, Fig. 132.) The screws G0 are driven by the wormwheels G' and worms G8 on the shaft G22, as already described.

The rods B aforesaid are inserted in the guide-tubes K2 one by one by opening the bottom of the guide-tubes, which are normally closed by levers KS, Figs. l2, l1, and l5, and the left-hand half of Fig. 8. These levers K7 are pivoted at K3 to the frame E underneath, and the springs K0 normally hold the other ends of the levers over the mouths of the guide-tubes. The springs are fastened to a sliding bar K10 behind the frame E, and this bar has a handle for easy manipulation.

/Vhen the guide-tubes K2 are filled with the rods aforesaid and the work-holder F has been moved after the holes have been drilled underneath the rod-driving mechanism, Fig. l0, the handle on the sliding bar K10 is pulled out, and the levers K7 are consequently pulled clear of the mouths of the tubes, as shown in dotted lines, Fig. la. lVhen the rods have been driven into the work, the handle on the bar K10 is pushed in, thus closing the mouths of the tubes again. 1n inserting the rods one by one the slots K11 in the slidingbar K10 allow sufficient movement to the levers K7 to insert the rods, and when the levers are released the springs K0 bring them back to cover the mouths of the tubes, as aforesaid. 1f this machine be mounted horizontally, it is evident that the levers KT and the additional parts just enumerated will not be required. 1n order to stop the travel of the tools 111 and K when the top or bottom of their travel is reached, there is provided a stop 11, secured to one of the flanges G, which moves up and down a rod 1110, to which are secured two adjustable stops 12122 and 1-12. The rod 12110 is supported in frame E and at its lower end is connected to the bell-crank lever 11122, the lower end of which is forked and engages the striking-bar G12 by means of a pin thereon. Vhen the feed-screws G0 descend to the bottom of their travel, the stop 121" encounters the stop 112, and the rod 1110 is moved down sufficiently to actuate the striking-gear, which disengages the pulleys G10 and G20 from the friction-clutches, (indicated by the letter 1.) To reverse the motion and to cause the feedscrews G0 to ascend, the striking-bar G12 is ac- IOO IIO

tuated by hand still farther in the same direction, causing the clutches indicated by the letter I to engage with the pulleys l?? and G2, whereby the drills are started revolving in the opposite direction and the feed-screws GG ascend until the stop Il encounters the stop H22, when the machine is again automatically stopped, and the farther movement of the striking-gear by hand again starts the machine in the direction to perform its functions.

Having thus described our invention and the manner in which the same is to be performed, We declare that what ive claim is l. In a machine for boring holes and driving rods or tubes into said holes, the combination of a gang of tubular drill-guides, drills revolved by and having endwise motion in their respective guides, a corresponding gang of tubular ram-guides, and rams having endwise motion in their respective guides, of mechanisms for simultaneously revolviu g the drill-guides and for imparting endivise motion to the drills and rams, for the purpose set forth.
