J'EWELERS DRILLINGfl-MACHINE.
SPECIFICATION formingpart of Letters Patent No. 269,174, dated. December 19, 1882,
Application filed December 3, 1881. (No model.)
To all whom it may concern Be it known that I, WALTER S. Bnowraa, a citizen of the United States, and a resident of the city and county of Albany, and State of New York, have invented certain Improvements in Bench Drilling-Machines for Jewel ers, Pearl-Setters, and Others, of which the following is a specification.
and adapted to be moved vertically in either direction or be wholly removed.
The object of my invention is to provide a light and convenient drilling-machine, which will be readily attached to a bench or table, for use of jewelers, pearl-setters, and others requiring accurate work, and will enable the operator to have full control over the work being done, both in holding the metal being operated with and guiding and controlling the movements of the drill and the table holding the work while being drilled, so that the drilling will be done atthe exact points in the metal required and to the depth designed by the operator revolving the driving mechanism of the drill with one hand, while he with the other hand holds the work to the table and elevates or lowers both together, as may be required. I attain this object by means of the devices constructed and arranged as illustrated tal view taken atline No. 1 in Fig. 1.
Arepresents the drill bracket-frame, inadeof metal, with substantially the form shown. Made with the upper portion of said bracketi'rarne are hearings to and b,-in which the vertical drill-spindle B is supported'and revolved. Secured in the upper end of bracketA, above bearing a, is the spindle c, on which is mounted the bevetgear 0, provided with crank-handle D for revolving said gear-wheel. Secured to drill-spindle B is the bevel-pinion E, which is actuated by bevel-gear 0.
Made with the rear side of bracket Al's the stationary clamping-jaw d, and at a distance of two inches (more or less) below said clamping-jaw is ear 0, which ear is pierced vertically and provided with a screw-thread, in which works the 'clamping-screwf, provided on its or less,) is a guiding or socket way, It, the bore of which socket is made with a uniform diameter and in aline parallel with the axial lineof drill-spindle B. The said socketguides table F in its vertical movement by means of the guiding-pin 1', made or attached to said table.
Ifpref'erred, the front side of socket It may be slotted, as shown at 0 in Figs. 1, 2, and 3, for receiving a bracing-piece,j, cast or made with both the table F and guiding-pin i.
If preferred,the guiding-socket may be dispeused with and a vertical rib castwith the breast of bracket A may be used for guiding the table in its vertical movements, and button-heads an, attached to said vertical guidingrib, may be employed to operateagaiust the marginal surfaces at the sides of slot 12, made in an angle-piece, 1), connected with table F, as shown in Figs. 4: and 5. Bracing-pieces made with angle-piece p and table F may be employed to stiffen said table with said slotted angle-piece. The said table, being thus held and guided in its vertical movements by the too guiding-pin iand socket It, may be readily elc vated by a hand of the operator for causing I operate by the same principles of mechanism the drill in drill-spindle B to enter to a greater or less depth into a piece of metal supported by said table, or lowered for withdrawing the drill. The clamping-jaw d and clamping-screw f operate to hold the drill-spindle and the gears actuating the same firm and steady, so that the operator is not required to exert himself in the least to steady the drill, as is required with breast or bow drills heretofore employed by the class or workmen my improved drill is intended for.
If preferred, a drill'chuck may be attached to the drill-spindle for holding different size drills.
The manner of operation to be had with my improved drilling-machine is as follows: The drilling-machine is to be firmly secured to the work table or bench by the clamping jaw and screw, and the piece of metal to be pierced is to be laid on the movable table.
, WVith the point the said piece is to he pierced I ver, are old and well known.
in a vertical line with the point of the drill. The operator will then with one hand graduallyforce the table, with the piece to be drilled, upward, while with his other hand he will impart motion to the drill by revolving gearwheel 0. When the drill has been made to enter the metal to the depth intended the operator will lower the table with his hand. In cases where the piece to be drilled is so large as not to be admitted on the table, the table may be readily removed by simply lifting it upward until the guiding-pin is free from the guiding-socket.
Iam aware that bench drilling-machines provided with clamping-jaws and clamping-screws for attachment to a table or bench, and made with a bracket for supporting a drill-shaft vertically over a movable table operated by a le- Such machines had the drill-shaft made with a spiral ribbed or screw form, and were operated by a reciprocating movement of the operators hand, in which the downward movement of the hand forced a fixed pin to be moved downward through the entire length of the spiral channel of the drill-shaft and gave a rotary movement to the same, which was continued by means of a balance-wheel provided on the shaft, while the pin was carried upward for another downward movement of the same to continue the motion. Such machines I do not claim as being my invention, as they do not or means, and are therefore not adapted for fine and accurate work, as required by jewelers, for the reason that the rotations of the drill in these older machines are not uniformly the same against the resistance attending drilling of metals, and the movement of one of the operators hands in a reciprocating manner, alternately forcible and light, tends to prevent his having accurate and complete control over the required movements of his other hand and the work the drill is operating with, while another defect is that when the work is not fixed to the drill-table the operator is required to call in the service of another to operate the drill, while he directs and controls the movement of the lever of the table and holds the work being drilled. My invention is intended to provide a drilling-machine with which a single person may operate the drill and hold and control his work and direct the movements'of the drill-table in an easy and convenient manner and by natural movements of his hands, so that the work will be accurately done, while the drill will be made to revolve uniformly the same with one hand and the work be held and directed in its movement toward the drill, whether faster or slower, by the other hand.
Having described my invention, what I desire to claim and secure by Letters Patent is 1. In a bench drilling-i'nachine, as my improvement, the work-supporting table unencumbered with mechanism for adjusting and holding the same atdifferent elevations suited to the work to be drilled, but free to be moved up and down by the hand thatclamps the work upon it, at the will of the operator.
2. In a bench drilling-machine, the cornbi' nation, with bracket-frame A, provided with a clamping mechanism for its attachment toa bench, drill-spindle B, held from being moved vertically, and gear mechanism U and E and crank-handle D for rotatingsaid drill-spindle, of the work-supporting table F, held in connection with said bracket-frame and unencumbered with adjusting and holding mechanism, but free to be moved up and down to ditferent elevations by the hand that clamps the work upon the table, at the will of the workman.
