the beams with a minimum of effort and exertion req ired. t
More specifically, the invention embodies the provision of a rail from which the drill is suspended and slidably mountedthereon together with means for pressing the drillagainst a beam in which the holes are to be drilled and including a lever pivoted to the rail and connected to the handle of the drill forvmoving the drill forwardly during the drilling operation.
A further object of the invention is to provide a drilling rig of this character of simple and practical construction, which isstrong and durable, which may be easily and quickly attached to a conventional form of electric drill and which otherwise is well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the de tails of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure -1 is a side elevationalview.
Figure 2 is a sectional view taken substantially on a line 22 of Figure 1.
Figure 3 is a sectional view taken substantially on a line 33 of Figure 2.
Figure 4 is a fragmentary end elevational view of the up er end of the lever.
Figure 5 is a side elevational View thereof.
Figure 6 is an end elevational View of the clip adapted for attaching the handle of the drill to the supporting rail and with the link connecting the lever with the clip shown in section.
Figure '7 is a side elevational view thereof.
Figure 8 is an end elevational View of the clip slidably supporting the drill on the rail.
Figure 9 is a top plan view of the link connecting the lever with the clip for the handle of the drill, and
Figure 10 is a side elevational view thereof.
Referring now to the drawings in detail wherein for the purpose of illustration I have 2 A A disclosed a preferred embodiment of the invention, the numeral 5 designates a rail of rectangular shape in cross-section and on which an inverted substantially U-shaped clip 6 is slidably mounted, the legs of the clip having screws 1 freely inserted therethrough forthreaded engagement with the opposite sidesof the handle 8 of a portable electric drill 9.
The clip 6 slidably supports the drill on the rail 5 and the central portion of the clip is offset as indicated at It to provide a recess II in its underside to snugly receive the edges of the .rail 5 during sliding movement of theclip and. to prevent lateral play of the drill on therail.
A second clip l2 of substantially inverted U- shaped formation has its upper portion formed with a substantially T-head l3 in which the rail 5 is slidably received, the legs of the clip l2 extending downwardly behind the handlel8 and have arms I4 welded or otherwise suitably s6 cured to the legs and projecting forwardly at opposite side of the handle .8 and provided with openings l5 adapted for selectivelyfreceiving bolts or. screws I6 for, attaching the front ends of the arms to the handle. A l
' A lever ll has its upper end pivoted between the legs 18 of a substantially U-shaped clip I9 by means of a pin 20, the cliplB beingslidably mounted on the rail 5 and secured in longitudinally adjusted position thereon by means of a setscrewZl, A A A A link 22 has its rear end pivoted to the upper portion of the lever by means of a pin 23 and extends forwardly for pivotalconnection between bar having longitudinally spaced notches 29 in its lower edge adapted for engaging a lug 30 formed in the bottom of the bracket 21.
A plunger 3| is slidably mounted in the top of 3 34 at its front end, the hook being adapted to engage a beam 35 extending downwardly from a deck head or similar structure 36.
By adjusting the rack bar with the hook 34 of the rack bar in clamping engagement with the beam 35 the drill 9 will be supported in a position for drilling holes in the beam 35, a forward pressure being exerted on th drill. by a. rearward movement of. the lower end of: the lever ll.
Where the decking 36 is formed with additional beams such as indicated at 31, sufiiciently.
close to the beam 35 to permit the rear end of end of the lever moves the drill on the rail, a rack bar having a, hook on one end adapted to extend the rail 5 to abut the beam 31, the rack bar 28 and hook 34 are not required and may be re-.
moved and by loosening the set screw 21' the rear end of the rail 5 may be slid outward in abutting engagement with a beam 31 and inv operation.
the drill slides forwardly on the rail bvmeans. of the sliding clips 6 and I2. The pin engaging the rear edge of the; handle 8 of the drill prevents pivotal'movemenir of the drill on the screws drilling operation;
The rai15 maybe easiiy removed from-theclip 6, l2 and. 19 by releasing theset screw 2!- and the clips Gand', ITmay-a-lsobe quickly detached from thehandle B of the drill for-interchangeable sew h Qther r l's; whe desired;
It is believed that the details of construction, manner of operation and? advantages of the device will be readily understood from the foregoing without further detailedexplanation. Having. thus described the invention, what I claim is:
