DRILLING M CHIN Application filed March 24,1925, Serial 1%;17334; v
I My invention relates to power driven, foot controlled drilling machines or drill presses as used by mechanics, especially wood work- I chine illustrated in the accompanying drawings and in which Figure 1 is a generalview in perspective of the complete machine, Figure 2 a perspective view of an angle plate which bolts to the slots of the work, table of the machine, Figure 3 abroken plan view showing the sliding motor carnage, guide rods and [stop collar or depth gage; Figure 4 an elevation 'ofthe depth gage and section of the guideirod which it embraceaandFigure 5 is a sectional-view of the motor carriage showing the upper end of the foot lever engaging a slot in the same.
In further detail the machine will be seen to comprise a suitable floor stand or frame 1 with a bed casting 2 bolted to its upper end supporting a work table 3 and a motor 4.
The motor is bolted at 5 to a base plate 6 in turn secured at 7 to a sliding carriage block 8 slidable horizontally toward and from the work table on two aligned round bars 9 supported above the bed plate on bosses 10 provided with V grooves 11 into which the ars are seated and secured to the bosses.
This construction insures absolute parallelism of the bars and consequent free sliding of the carriage in a cheap construction easily made.
The sliding carriage block 8 is centrally slotted at 12 as shownin Figures 3 and 5 to receive the rounded. upper end 13 of a lever 14; and the rounded end 13 is relieved at 1.5 so that the lever may work freely in the slot to move the carriage backand forth. The lever 14 is pivotally supported at 16 on a bracket 17 secured to a cross member 18 of the frame and is provided with a horizon-" tally and forwardly extending foot treadle portion 14' having its outermost end flattened at 14 to receive the foot of the opera- 1 tor, and a spiral spring 19 tensioned between the lever 14 and the bed 'of the machine drill from its work when the machine is in Directly secured to thespin'dle of the motor' is a drill chuck 2O adaptedto receive a standard drill, and if desired a multiple drilling head may be substituted for the single drill. chuck andsuitably braced to prevent rotation as a whole. w
The work table 3 is provided with a verti cal wall 3 lying in a-plane at rightan gles to the axis of rotation ofv the drill chuck and is formed with-a-ve-rtical slot 3 for the passage of a drill at various elevations of the table. The table is also provided with a detachable angle bar 21 shown inIFigure 2,
and which boltsfto the slots22in thework table by means of the b0lts-23, and the angle 1 bar beingslotted at 24 for the passage 'of the bolts is adjustable to any angle when place onthe'tabl'e v e. a. I The table is'secured.,to'two verticallydepending bars 25 which are verticallyslidable in bosses26 casttothe bed ofthe machine and is provided with tension springs 27 to pull the work table downward, while it may be adjusted upwardly to any height within the limit of its guiding bar-s25 by the hand screw 28 threaded through a boss on the bed plate and bearing against the lower side of the table to push it upwardly against the resistance of the springs.
The vertical adjustment of the table 3 is from a position considerably below the center of the drill chuck to aposition about the same height above it. a
The table would'ordinaril'y fall by gravity without the aid of springs 27 but the use of the springs in the position shown pullin from the table to the bed, makes the mesh smooth and overcomes any tendency for the table to stick. 1
To adjust the depth of the hole being "drilled, I provide an adjustable stop or gage 29 preferably positioned on one of the cartion of the carriage, and one corner of the carriage block is convenientlynotched at 30 reduce the guiding limit of the bars. The stopissplit through one side and clamped to the bar by the bolt 31 as indicated in Figures 3- and 4,' and while this stop as described forms an efiectivedepth gage, it is capable of considerable modification.
In operation the desiredxdrill is placed'in the chuck 20,- the motor started; work placed riage guidebars 9 to limit the forward moto receive the stop so that the latter willnotno i desired.
Large Work is u'suallysupp'orted on the tablebe'tween the Wall 3 and the angle bar 21 Which is bolted to theslots of table-outside of the Work so as to hold it against the "'fe'dof the drill.
This arrangement or horizontal table with its Vertical Wall and auxiliary angle bar has been found. a great improvement in its 'adaptability'to a'variety of Work-and utmost speed of operation, as it prov'ides for a numher of'difi'erent positions for the Work With minimum adjusting of the machine.
I claim: I v I 1. In a drilling machine of the'character described, a floor stand, a pair of horizontally arranged bars thereon supported by and'above'the upper end of the stand, and a drilling carriage block slidahly mounted'on Y said bars, said bars being seated "and secured in vertically open horizontal grooves formed ontop of-the stand and the bars being removable vertically from the open sides of the grooves.
52. In a drilling machine of the character described, a flow-"stand supporting a horizontally slidable carriage block, a foot lever provided With arms extendingsubstantially at right angles to one another pivot'ed'at thejunction of the arms to'the stand'jvvith one of its arms extending horizontally as a foot lever and the other arm being rounded at its endand operative directly against the carriage in a slot therein. I
' 3. In a drilling machine including a drill chuck mounted to revolve on a horizontal axis, a Work table positioned in front ofthe chuck arranged in a horizontalplaneand provided with a vertically extending-plain Wall along its edge nearest the chuck, 'said Wall having a' relatively narrow vertical slot therethrough for the passage of the drill and adapted for the placing of Work for drilling along either side thereof, and'th'e'table being immovable on its mounting in a lateral direction and provided With Work bolting slots extending at right angles tosaid wall the chuck.
