ERNEST J. ALLEN, OF ELMI'IURST, NEW YORK.
DRILL-SLOTTEB.
Application filed November 8, 1919.
To all whom it may concern:
Be it known that I, ERNEST J. ALLEN, a subject of the King of Great Britain, and resident of lillmhurst, Long Island, in. the county of Queens and State of New York, have invented certain new and useful luv provements in Drill-Slotters, of which the following is a specification.
This invention relates to improvements in machines for performing slotting or other similar machining operations. The main object of the invention is to so design and construct the necessary parts that the entire device may be applied to the table of an ordinary drilling machine and be driven by the drill spindle with the ordinary drill socket. My invention, in its preferred form, embodies an inexpensive attachment for a drilling machine whereby simple slotting or other similar operations may be performed thus obviating the necessity of having an entirely separate and expensive machine for this purpose. A further object of my invention is to provide a substantial and rugged design adapted to furnish a wide range of speeds and suitable for various classes oi work, but which can be manui'actured and sold at a very small part of the price ordinarily charged for machines designed to accomplish the same work. My improved device is sufiiciently light to permit of its being readily lifted on to or oif the drill table and is so constructed as to permit of its being rigidly secured in place or detached in a very few minutes. The device may be used for cutting key-ways, straight or at an angle, slotting rectangular holes, profiling, cutting clearance on dies, filing and many other similar small jobs of this class which ordinarily require the use of a large machine.
In the accompanying drawings I have illustrated one embodiment of my invention although it will be evident that various other forms may be readily designed within the scope of my invention and various changes in detail and arrangement oi. parts .may be made within the spirit thereof.
In, these drawings:
Figure 1 is a side elevation, certain of the parts being shown in a central vertical section;
Fig. 2 is a face view of the eccentric driver;
Specification of Letters Patent.
Patented Feb. 8, 1921.
Serial No. ssaeco;
Fig. 3 is top plan view of the head portion; and
Fig. 4: is a front elevation.
In the specific form illustrated the machine includes a base 10 adapted to be rigidly bolted to the table of a drill press or to any other suitable support. This base has an upwardly extending. standard for sup porting the operating parts. This standard may, in some constructions, be of a single piece, but where adjustment is desired, it may be made of separate sections adjustably secured together to permit a raising or lowering of the operating parts. Merely tor purpose oi illustration, I have shown the base provided with an upwardly extending standard section 11 integral therewith to which is bolted an upper section 12, there being a plurality of bolt holes whereby the parts may be secured together with the upper end of the standard 12 at different elevations above the case 10. The upper end oi? the standard is shown as providing a bearing 13 for a substantially horizontal shaft 14; and a bearing 15 for a substantially vertical shaft 16. These two shafts are connected by suitable gearing, for instance, miter- gears 17 and 18, to drive the shaft 14: at the desired speed.
The upper end of the shaft 16 is so con structed that it may fit into the ordinary drill socket on a drill press and the shaft be rotated with the drill socket in place of the ordinary drill. This upper end portion of the shaft may thus be varied in accordance with the shape, size and kind of the drill socket with which the machine is to be used. A forwardly extending arm portion 19 on the standard has a vertical guideway within which the tool carrier L0 may reciprocate. This tool carrier is shown as having opposite bevel side itaces engaging with corresponding flanges 21 and 22 at the front end of the arm 19, one of these flanges, for instance 22, being adjustable and removable to provice the desired clearance and for easy assembly. The center line of the tool carrier 20 preferably intersects a projection of the axis of the shaft 14-, and the guideportion is supported by side members spaced to form a chamber or aperture in the rear of the guide. Within the chamber are mounted the gears 17 and 18 and suitable driving connections between the shaft 14 I the pitman.
and the tool carrier. The driving connections are illustrated as includin a pitman 23 journaled on a bolt 21- rigidly secured to the upper end of the tool carrier. Preferably the belt 2 1 is mounted in a slot 25 so that the tool carrier may be raised or lowered in respect to the limiting positions of The lower end of the pitman has eccentric connections to the shaft 1 1-. To provide for varying the length of stroke of the tool carrier, the outer surface of the miter gear 18 has a radially extending flange 26 provided with a slot 27 within which a crank pin 28 may be rigidly secured. This pin may be adjusted lengthwise of the slot so as to vary the diameter of the circle in which it travels thereby varying the stroke of the tool carrier.
The tool may be secured to the lower end of the tool carrier in various ways, but preferably so as to permit of a rotary adjustment of the tool about its axis. The tool is shown as having a cylindrical shank 29 projecting into a chamber or cavity 30 in the lowerend of the tool carrier. A simple and efficient way of rigidly connecting the two includes the use of a pair of U bolts encircling the tool 29 and having their ends projecting through the front wall 32 of the tool carrier and'provided with suitable retaining nuts, whereby the tool may be held in place or when loosened may be rotated about its axis to any desired adjustment.
Although my improved device is preferably intended for use on a drill press and to be driven from the drill socket, I may provide additional or substitute means whereby the shaft 1% may be driven from some other source of power. Merely as an example, 1 have shown the standard provided with a bracket 34. carrying a shaft 35 on which is secured a drive pulley 3'6'adapted to receive a belt. The shafts 35 and 14: are parallel and may be connected to be driven at any desired relative speeds by appropriately sized gears 37 and 38.
in order that the work maybe properly mounted and moved in respect to the tool, 1 provide a work table d0 which is capable of adjustment in three directions. The table is shown as being pivotally mounted upon a slide d1, this pivotal mounting including a transverse pivot bolt 42 at one end and slotted flanges 413 at the opposite end. Bolts 14: carried by the slide 41 project through the slots and the slots are curved with the pivot 42 as a center. The end of the table the table d0 may be moved forwardly or backwardly and laterally in either direction in respect to the tool. buitable means may be provided for giving to the slides 11 and d5 the desired adjustment. As shown, the lower slide 45 carries a screw bolt d6 with an operating handle 47 and is threaded through an upstanding lug 18 on the base. The slide 11 carries a transverse screw belt 419 with an operating handle 50 and this is threaded through an upstanding lug 51 carried by the slide 4:5. By turning the handles i7 and 50 the table 4:0 may be moved to bring the work to the desired initial position and the work may then be slowly fed in a suitable direction while the tool is operated thereon. The table may have the ordinary means for facilitatingthe attachment of the work thereto. As shown it has a series of undercut grooves 52 in the upper side thereof.
Having thus described my invention what 1 claim as new and desire to secure by Letters Patent is:
1.
