IMPROVEMENT IN HAND-DRILLS.
'Specification forming part of Letters Patent No. 124,681, dated March 19, 1872.
' To all whom it may concern:
Be it known that I, Lo Urs HILLEBRAND, of the city` and county of Philadelphia and State of Pennsylvania, have invented ainew and useful Hand-Drill Press; and I do hereby declare the following to be a clear and exact description of the nature thereof, suiiicient to enable others 'skilled in the art to which my invention appertains to fully understand and use the same, reference being had to the accompanying drawing 'making part of this specification, in which the figure is a side View ofthe device illustrating my invention.
My invention relates to a hand-dril1 press, which may be used for various purposes7 and in places where a large press could not be manipulated or located. It consists ofa curved arm with a screw-boss and bed-plate, and a screw having a handle and turning in and through the boss, and with the drill which is secured to and turns with the screw.
Referring to the drawing, A represents a Y bed-plate, from which rises an arm, B, formed on or about its upper end, with a boss, C, in which is fitted a screw, D. This screw, which I term the feed-screw, is formed with a handle, E, and carries a drill, F, which is firmly fixed or secured to said screw, so as to follow its various motions.
In operation, when a hole is to be made, the handle E, being properly rotated, causes the screw to descend and carry with it the drill, which likewise rotates and descends, thus boring its way into and through the meta-l, and accomplishing the object ofthe invention.
The slightest turn of the screw will cause a corresponding descent and rotation of the drill and` consequent action upon the metal, so that holes may be certainly, quickly, and easily drilled. The reverse rotation of the screw will withdraw the drill from the metal,.an operation heretofore accomplished by the action of a spring, a swivel connection between the screw and drill, or some other mechanism, which, however, complicates the construction of the press.
In common drills or drilling-machines, the drill is not forced down by the screw to which it is attached, but by some otherI power or pressure; and in some other drills or machines, the drill turns independently of the feed-screw,
and requires separate contrivances or mechansupported on frame-work having clamps or confining pieces, the whole being adapted for heavy work, such as car-wheels, tires, etc., but
'in my invention the article to be drilled will rest on the bed, and while being drilled will come to a bearing or stop against the curved armbor the latter bear against the article to be drilled', so that fastening clamps are unnecessary, and as the article can be bored at anyv point, owing to the bed being clear at all sides, the eccentric or adjusting plate or nut is useless.
In some cases, as where a hole is to be drilled in the face-plate of the lock of the trunk, the bed and arni are hooked or placed over the top edge of the trunk, with the bed behind the front side of the trunk. The screw is turned, and when it reaches the face-plate the arm turns and rests on the top edge of the trunk, and causes the press to remain in place, no fastenings of any kind being necessary.
As the device described by me, as in existence, is complicated in form, and is not designed for service of the kind performed by my device, v v
I claim as an improvement- The. hand-drill press, consisting of the curved arm B, with screw-boss O and bedplate-A, in combination with therotatin g screw l), having handle E, which screw turns in and through4 the screw-boss, and carries the drill secured to and rotating with Vthe screw, all constructed, arranged, and`operating as described.
The above signed by Ine this 10th day of November, 1871.
