JMPROVEMENT IN METAL-DRILLING MACHINES.
Specification forming part of Letters Patent No. 140,925. dated July 15, 1873; application filed May 24, 1873.
To all whom it may concern:
Be it known that I, JACOB (l. KELLER, of Philadelphia, Pennsylvania, have invented certain Improvements in Drill Presses, of which the following is a specification:
The object of myinvention is to so construct a drilling-machine that it can be made to bore.
of the machine consist of the base A and standards B and D secured to the said base, and the adjustable portions consist of the frame B carrying the drill-spindle a, and hinged to the standard B, the table F adjustable vertically on the standard B, and the slide G adj ustable on the standard D. The latter may, if desired, be made detachable. The frame B is hinged to the upper end of the standard B by a sleeve, H, best observed in Fig. 3, the said sleeve having at one end a head, and at the other a nut, so as to maintain the frame and standard in close contact with each other, and
yet permit the frame to turn freely on thesleeve. The frame and standard are further secured together by ascrew, 11, passing through a curved slot, 0, in the frame B and into the standard. I is the driving-shaft, turning in projections i i on the standard B, and having the usual cone-pulley J, one end of this shaft having a bevel-wheel, K, gearing into a similar wheel, K, on a shaft, L, which passes through and is arranged to turn freely in the sleeve H, the opposite end of this shaft having a bevel-wheel, M, gearing into a similar wheel, M, from which the desired rotary mo tion is communicated to the drill-spindle a through the medium of thegearing shown in the drawing, or any other equivalent mechanism. The feeding of the drill-spindle may be accomplished by hand or automatically by the aid of appliances common to other drillingmachines. One end of the table F is so adapted to guides formed on the standard B as to admit of vertical adjustment only by means of a screw or rack and pinion or other devices commonly used for the purpose. To a vertical slotin the standard D is fitted a slide, G, which can be raised or lowered at pleasure; and to this slide a bearing, m, is so hung as to be selfadjusting to any angle assumed by the drillspindle, but is not permitted to have any other movement. On loosening the screw 7) the frame B can be adjusted to any angle which the hole to be drilled may demand; but in most cases the holes to be drilled are either vertical and at right angles to the face of the table, or horizontal and parallel with the table; henceit is important that the frame should be promptly and accurately adjusted, so that the -drill-spindle shall occupy either of these two extreme positions without resorting to any calculations or measurements, and this I accomplish in the following manner:
The top w of the guide 61 is in a horizontal line drawn through the center of the sleeve H, and when the projection n of the adjustable frame B is in contact with this top of the guide the drill-spindle will be exactly at right angles to the face of the table, as shown in Fig. 1, and when the rib e of the frame B is in contact with the upper edge f of the standard B the drill-spindle will be parallel to the face of the table, as shown by dotted lines in Fig. 1;
hence, after the machine has been used for ing will accommodate itself to the drill-spindle, whether the latter is in a horizontal position, or has been adjusted to any angle, the steadinient of the spindle, when it is in a vertical position, being effected by causing the boring-bar to turn in a hole in the table.
I claim as myinvention- 1. A drilling-machine in which a frame carrying the drill-spindle is hinged to the permanent frame or standard, having a verticallyadjustable table, all substantially as described, so that the drill-spindle can be adjusted to a position at right angles, or at any other angle, to or parallel with the table, as set forth.
2. The adjustable frame B carrying the drill-spindle, the fixed frame B, and the connecting-sleeve H, in combination with a shaft, L, passing through and turning in the said sleeve, and the gearing described, or its equivalent, by which the said shaft derives its motion from the driving-shaft and transmits it to the drill-spindle.
3. Tops or shoulders 00 and f arranged on the fixed frame or standard B, in the manner substantially as described, in respect to the adjustable frame B and to the table F, so as to insure a proper adjustment of the drill-spindle at right angles to or parallel with the table, as set forth.
4. The combination of the adjustable frame carrying a drill-spindle with the slide G and its vibrating bearing m.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JACOB O. KELLER.
