DRILLING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 441,756, dated December 2, 1890. Application filed July 15, 1890- Serial No. 358,823. (No model.)
To all whom it may concern:
' and WILARD GARBRANT, citizens of theUnited States, residing at Waterloo, in the county of Black Hawk and State of Iowa, have invented certain new and useful Improvements in Drills, of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a side elevation of a drill embodying our invention. Fig. 2 is 'a cross-sectional view on the line 00 w of Fig. 1.
Our invention relates to certain new and useful improvements in drilling appliances, and especially to that used for drilling railroad-rails, and consisting in the constructions and combinations of devices which we shall hereinafter fully describe and claim.
The object of our invention is to provide a cheap and simple portable apparatusbymeans of which holes may be drilled in railroad-rails and like devices while the same are in position and without necessitating the removal of the same.
To enable others skilled in the art to which our invention appertains to make and use the same, we will now describe its construction and indicate the manner in which the same is carriedout.
In the said drawings, A represents a suitable frame, consisting of the uprights a, a, and b :and the base-piece c, the said piece 0 having a horizontal arm d, which is.bolted to a similar arm of the piece a, and said piece a being bent to form a vertical arm 6, whose lower end is inclined and bolted or otherwise whereby they are firmly held together and capable of adjustment to correspond with the size of rail operated upon, and said arm B has its outer end bent downward at f or hookthis means the rail is securely held at top and bottom and the drilling-machine held firmly to the rail, so that its drill may operate to bore the hole, as we shall hereinafter indicate.
The base-piece 0 may have. secured to it lugs or cars g, between which the upright b is secured, and one end of said base-piece c v slotted to provide for the vertical adjustment of the frame and the working parts of the device, this being often desirable because of the rails being of different heights. Secured to the base-piece c is a transvers bar C, which is designed to rest upon the roadbed or tie and form a strong support for the device, and to the upright a is secured the upper end of brace-rods D, whose lower ends are bolted to the cross-bar C. v
Mounted in the lower portions of the uprights a and a and the upright 11 is the drillshaft E,which is provided with a feather-way g, whereby said shaft may be longitudinally moved, and said shaft carries at its outer end a head h, in which the drilling-tool F is secured in any suitable manner. Upon the shaft between the head h and a collar h is a sleeve G, externally threaded and passing through a threaded nut or hearing in the upright b, and is provided with a ratchet-wheel.
this gear-wheel J in turn meshes with and is driven by a gear-wheel K on a shaft L, mounted in the upper portion of the frame between or in the uprights a and a, and is extended outside of said frame to receive a crank-handle L, by which the gears are operated. From this description it will be seen that when the handle L is turnedthe gears I, J, and K are set in motion and the drilling-tool rotated.
To provide an automatic feed for the drill we employ the following mechanism: Upon the shaft L, near the inner face of the vertical portion e of the upright a, is mounted an eccentric M, and pivotally secured to thelower portion of an arm Z, extending from the portion 6 of the upright a, is a lever N, whose or is formed with a wide pawl P, which is adapted for engagement with the ratchetwheel II on the sleeve G.
From the foregoing it is manifest that as the crank is turned to operate the gears and thereby rotatethe drilling-tool the eccentric M is also rotated, and by contacting with the inner walls of the yoke 0 causes the lever N to oscillate, and thereby causes its pawl to antomatically engage and move the ratchetwheel H and regulate the feed of the drill,
the pawl P being wide enough to feed the drill forward the desired distance without disengaging therefrom.
The apparatus described is simple. in construction, portable in its nature, not liable to get out of working order, and is very effective in drilling bolt-holes in the rails while they are in position 011 the road-bed. The adj ustment of the parts is quickly accomplished and the drilling quickly performed, as the operation of the drill is a continuous one and not intermittent, as are many of those now in use.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
1. In a drilling-machine, the frame consistin g of the uprights and base-piece, adjustable with relation to each other, said base-piece having an upturned end for engaging the lower flange of the rail, a two-part arm pivotally hung to said frame and having a hookshaped end for engaging the head of the rail, and a transverse support and brace-rods, in combination with the gears I, J, and K, mounted in said frame, a crank for operating the gears, a horizontally-moving drill-shaft, and
a drilling-tool carried by the shaft, substant-ially as herein described.
2. In a drilling-machine, the frame, the drillshaft and its tool, and the gearing by which the same is operated, in combination with means for automatically feeding the drill forward, consisting of a threaded sleeve on the drill-shaft, having a ratchebwheel, an eccentric on one of the gear-shafts, a pivoted lever
