Drawer 370, Edna, Tex. Filed Aug. 4, 1959, Ser. No. 831,575 4 Claims. (Cl. 7762) This invention relates to new and useful improvements in a plate boring device.
It is an object of this invention to provide a means for boring holes in building plates ditficult to reach with ordinary drilling tools.
It is another object of the invention to provide means for drilling holes in plates of building structures having novel means for maintaining the tool in position during drilling operations.
It is still a further object of the invention to provide a means for drilling holes in plates of buildings having novel means for adjusting the tool for drilling at various angles.
In installing electrical conduits in buildings already constructed, it is customary to bring the conduit into the upper portion, or attic, of the structure by passing the conduit between the walls of the building and up through the plate adjacent the roof structure. The space available for Working in this area is very restricted and it is often difficult to position a drill in this area at the desired angle in order to drill through the plate. Flexible cables have been employed to permit the drill bit to be positioned in the restricted area, but Without means for maintaining the drill bit at this angle, it is very difiicult to obtain the desired angle of perforation. It is an object of this invention to provide means for accomplishing such an operation having novel holding means and a novel bit and guide as well as a novel means for varying the angle of perforation in accordance with the need.
With the above and other objects in view, the invention has relation to certain novel features of construction, operation and arrangement of parts more particularly defined in the following specification and illustrated in the accompanying drawings, wherein:
FIGURE 1 is a top perspective view of the device with a drill attached in dotted lines.
FIGURE 2 is an end elevational view showing the device applied to a building structure.
FIGURE 3 is an end elevational view of the device applied to a building structure at another angle.
FIGURE 4 is an enlarged side elevational view, in cross section, showing the bit guide and holder.
FIGURE 5 is a top plan view taken on the line 5-5 of FIGURE 4.
FIGURE 6 is a cross sectional elevational view of the cable guide, and
FIGURE 7 is a cross sectional elevational view of the holder spike and extension.
Referring now more particularly to the drawings, the numeral 1 designates a platform having prongs 2, 2 on the bottom thereof for engagement by penetration into the building plate as 3. A pair of rigid supports 4, 4 are mounted on the platform 1 having longitudinal slots 5, '5 in which the bracket 6 is adjustably mounted by means of the bolts 7, 7. An annular member 8 is mounted in the bracket 6 and has internally threaded sockets into which the ends of the bolts 7, 7 extend to lock the bracket 6 and member 8 together. The member 8 is internally threaded axially to receive the externally threaded insert 9 which has the axial passageway 10. The insert 9 may be of various sizes, with relation to the axial passageway 10, to accommodate varied sizes of bits.
The bracket 6 is integral with the collar 11 of the cable guide 12. A sleeve 13 is mounted over the opposing end of the cable guide 12 and the cable 16 extends Patented Oct. 31, 1961 through the sleeve 13 and guide 12 and is anchored to the drill connection 14 as by suitable set screws 15, 15.
A slot 17 is formed in the platform 1 between the supports 4, 4 through which the bit 18 and cable 16 extends. A stop 19 is mounted adjacent one of the supports 4, which is tapered at its outside end, and an outwardly extending lip 20 is formed in the platform 1, the stop 19 and lip 20 providing a rest for the member 8 when an extreme angle cut is being made.
On the platform 1, adjacent the supports 4, 4, are the supports 21, 21 to which the externally threaded shaft 22 is pivotally mounted as by the pin 27. An internally threaded rotating member 23 is mounted on the shaft 22. Upstanding on said member 23 is the spike 24, which is pointed at its upper end. A shoulder 25 is provided between the rotating member 23 and the spike 24 on which the bottom end of the extension spike 25 is seated where an extension is needed. The spike 24 is tubular to receive the end of the shaft 22 when in retarded position, and the extension 25 is also tubular so that it will fit over the spike 24.
When it is desired to drill through a plate as 3, the platform 1 is placed on the plate 3 at the desired position, and the rotating member 23 is rotated, raising the spike 24 into contact with the roof 28 and the point of the spike 24 penetrates the material of the roof and causes the prongs 2, 2 to penetrate the plate 3, securely anchoring the platform 1 in position. The bracket 6 is adjusted to the desired angle of penetration and the bolts 7, 7 tight ened to maintain this position. An electric drill may then be attached to the drill connection 14 and the drilling action commenced. As the bit 18 cuts through the plate 3, the sleeve 13 moves the cable 16 through the guide 12. The bend in the guide 12 adjacent the bracket 6 is sufficient to permit the worker to handle the drill and guide away from the juncture of the plate 3 and roof 28 where there is room to work but will still permit adjustment of the bracket 6 to direct various angles of penetration.
The stop 19 is tapered downwardly at its outside end to limit the extreme angle of penetration, but is flat over the rest of its upper surface so that the bracket 6 may be leveled for a straight transverse penetration if desired.
While the foregoing is considered a preferred form of the invention, it is by way of illustration only, the broad principle of the invention being defined by the appended claims.
