JAMES L. JONES, OF STARBUOK, WASHINGTON.

DRlLLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 611,173, dated September 20, 1898. Application led May 15, 1897. Serial No. 636,742. (No model.)

To all whom, it may concern:

Be it known that I, JAMES L. JONES, of Starbuck, in the county of Columbia and State of Washington, have invented certain new and useful Improvements in Drilling-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in means for applying copper plates to steel or iron vessels, an especial object being to bore holes in the rivets, said holes being tapped to receive copper pins or pegs that secure the copper plates in place.

A further object of the invention is to provide an apparatus for boring the holes which will drive a series of drills or boring-tools and properly feed the same to the work, the drills being susceptible of independent adjustment as to distance apart and to and from the work upon which they are operated.

The invention contemplates a construction in which the severalY drills are carried by a movable frame which feeds them uniformly upon the work, the said drills being geared to the driving-wheel or power mechanism in such manner that they can be adjusted laterally with respect to each other and also have an independent vertical adjustment to accommodate any unevennessinthe plate or object with which they en gage or operate upon.

With the above objects yin view the invention consists in the manner of applying the copper plates and in the apparatus providing a stationary frame presenting guides, a second frame movable within said guides and carrying bearings in sliding engagement therewith,the bearings supporting transverse merals thereon, and what I consider to be the novel features of construction are specifically recited in the claims.

In the drawings forming part of this speci iication, Figure 1 is a sectional view showing the manner of applying the copper plates. Fig. 2 is a side elevation of a drilling-machine constructed in accordance with my invention. Fig. 3 is a plan view of the machine. Fig. 4 is an end View thereof. Fig. 5 is a transverse sectional View through one of the supports and boxings carried thereby. Fig. 6 is a detail view of one of the pinions to which drills 'or boring-tools are adj ustably attached. Fig. `7 is a detail section taken on the line a: of

Fig. 3.

Regarding the apparatus and referring to the drawings by numerals, l 1 designate the corner-pieces of the stationary frame, which are connected at their upper ends by crosspieces 2 and at their lower ends by crosspieces 3 3, leaving a space between for the drills or boring-tools. VBetween the cornerposts l is a plate 4, which is also secured to the cross-pieces. The plate 4 has a large circular opening in its center and is grooved or rabbeted along the edge of said opening to receive a rotatable disk 4a, having a rectangular opening 41?, and grooved or rabbeted along the edges of said opening to form guides for bearings or boxings 5 5, which are adapted to slide thereon. These boxings form supports for the frame, consisting of the side pieces 6 6, connected by the end pieces '7 7, from which extend trunnions 8, which are passed into openings in the movable bearings or boxings 5 5, said boxings being provided with set-screws 9, adapted to bear upon the trunnions to secure the proper level or'inclination of the frame. The side pieces 6 6 of the movable frame, which is located within the stationary frame and in sliding engagement with the horizontal pieces thereof, extend nearly the entire distance between said side pieces and form the supporting means for the mechanism which operates the drills or boringbearing-plates at the center of the movable frame support a transverse shaft, upon which is mounted a sprocket-wheel l2, said shaft having a bevel-wheel 13 in mesh with a horizontal bevel-wheel 14, supported by one of the bearing-plates and connected to a vertical shaft 15, having a crank-handle 16. The bearing-plates which support this part of the mechanism may be rigidly secured to the central portion of the movable frame, as the sprocket-wheel 12 forms the driving-wheel. The other bearing-plates are preferably movable upon the side pieces and when adjusted thereon are held by set-screws 17, and it may be here mentioned that the sets of bearingplates correspond in number with the number of drills or boring-tools with which the device is intended to be supplied. Each set of bearing-plates supports a transverse shaft 18, having a sprocket-wheel 19 thereon of the same size as the sprocket-wheel 12, and said shaft has a bevel-wheel 2O in mesh with a horizontal bevel-wheel 21, the latter having an enlarged hub or axle 22, which engages its bearings and perlnits of an axial opening being formed in the beveled wheel. This axial opening is preferably square to receive the shank of a bit or boring-tool 2.3,which is held in place byaset-screw 24E. Over the sprocketwheels 12 and 19 passes an endless sprocketchain 25, a-nd this sprocket-chain is held into proper engagement with the intermediate sprocket-wheels by means of :idle-pulleys 26, supported by vertical bars 27 ,carried by plates 28, which are also in sliding engagement with the side pieces of the movable frame and held in adjustable position by set-screws. The idle-pulleys are adapted to bear upon the upper and lower portions of the endless chain, and by having them adjustable upon the movable frame they can be brought to accommodate the position of the intermediate sprocketwheels. It will be understood, of course, that each horizontal bevel-wheel 2l is adapted to carry a drill or boring-tool which, being detachably connected thereto, will permit the number to be decreased as desired. In order to raise and lower the movable frame when desired, it is connected to a lever 29 through the intervention of a rod 30, cross-barSl, and rods 32, the latter being attached to the end pieces of the said arm, while the lever is pivoted to the upper cross bar or bars thereof. The lever may have a sliding dog or pawl and engage a segment-rack and hold the same elevated when settin g the drills.

The machine hereinbefore described is especially adapted for use in copper-plating iron or steel vessels, in which the device can be suitably clamped against the side of the i jvessel and by operating the crank-handle 16 lat one time.

the steel plating are tapped, so that when the copper pins or pegs 33 are driven therein they will be firmly held in engagement therewith, being headed to hold the plates in place. This forms a simple and effective manner of applying copper plates to steel or iron vessels.

From the foregoing description of the apparatus, in connection with the accompanying drawings, the construction and operation of the same will be readily understood, for when the drills or boring-tools are properly set, with the movable frame elevated, the lever is released, and by turning the crankhandle the several boring-tools will be rotated or turned simultaneously through the intervention of the sprocket chain and wheels, and the weight of the said movable frame and parts carried thereby will be sufficient to properly feed the drills or boring-tools. By supporting the movable frame on trunnions, in connection with the boxings, as hei-einbefore mentioned, the said frame can be swung at an angle, when desired, and held by the setscrews 9. The idle-pulleys serve to insure the proper engagement of the sprocket-chain with the intermediate sprocket-wheels, and as the supports of the idle-pulleys are adj ustable upon the frame they can be moved to accommodate the adjustment of the said intermediate sprocket-wheels.

By means of the particular construction and arrangement of the parts which make up my improved drilling-machine I provide for a very wide range of adjustment both in regard to the spacing of the bits or boring-tools and also to insure their proper engagement with the work when the surface is uneven.

This machine greatly reduces the work of drilling holes in rivets for plating vessels, as a number of drills or boring-tools are driven by the operation of a single crank-shaft.

It is apparent that instead of operating the crank-shaft 15 manually it could be driven from an engine-or other power.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. In a drilling-machine, the combination with a stationary frame, of a frame movable therein, adjusting means therefor, bearingplates independently adjustable longitudinally upon the movable frame, transverse shafts mounted in the bearing-plates and adjustable therewith and geared to horizontal pinions having axial openings, bits or boring-tools secured within said openings, and means for driving the several transverse shafts in unison, substantially as shown and for the purpose set forth.

2. In a drilling-machine, the combination with a stationary frame, of a frame movable therein and having guides, bearing-plates mounted upon the frame by engaging the guides, said bearing-plates being secured in adjustment by set-screws or equivalent devices, transverse shafts, supported in the adjustable bearing-plates and having sprocket- IOO IIO

Wheels mounted thereon, horizontal pinions also supported by the bearing plates and geared to the sprocket-Wheels, said horizontal pinions having axial openings to receive the bits or boring-tools, a sprocket-chain connecting the sprocket-Wheels, and means for driving one of the sprocket-Wheels, substantially as shown and for the purpose set forth.

3. In a drilling-machine, the combination with a stationary frame, of a frame movable therein, and having a series of bearing-plates adjustable longitudinally upon the movable frame, horizontal pinions supported in the boring-tools, means for driving the horizontal pinions in unison and from a single drive- Wheel, together With a lever connected to the movable frame for raising and lowering the same, substantially as shown and for the purpose set forth.
