HOLLOW AUGER.
Specication of Letters Patent.
' Patented any a, fait.
Application filed January 11, 1916. Serial No. 71,512.
To @ZZ whom t may concern.'
Be it known that I, JOHN F. ALEXANDER, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Hollow i ugers, ofI which the following is a Aspecification. l
The present invention relates to improvements in hollow angers, and particularly such an auger for making holes in plaster wall whether ceiling or side, for the reception of electric outlet boxes,
and fixture connecting devices. An object of the invention is to provide such a device which may be operated in a quick and eilicient manner and will make a. clean cut and properly posi- .tioned opening about a given center. An-
provide a device ofA this' other object is to character which will be entirely self contained and will receive and retain all material cut from the ceiling or side wall thereof, enabling such work tor be done withy out dirt or dust and Without the necessity for a screen or umbrella to catch lthe debris,
expensive rugs or IVith these and other objects in view, my the accompanying drawings, and will be hereinafter more fully described with reference-thereto and finally pointed out in the claim, 'v
In the accompanying drawings;
Figure 1 is a perspective view ofmy improved invention. y
Fig. 2 is an end view thereof.
Fig. 3 is a bottom view thereof.
Fig. 4 shows the same in engagement with the ceiling and before starting the boxing operation.
Fig. 5 shows the auger when half way of the ceiling, and v Fig. 6 shows the work completed, and the material cut from the ceiling contained in the auger.-
Similar reference characters indicate corfigures of the drawings.
Y Referring to the drawings, my invention comprises a hollow cylindrical shell or body portion 10 provided at its forward edge with a series of cutting plate'12 provided with a of screwsl.l This plate is preferably provided with several enlargedsegmental .openteeth 11, andat its op? ings 14 therein to diminish the weight of material. Spaced from the plate l2 there is provided within the cylindeii 10 a transverse plate 15 having a central opening therein and secured within the cylinder by means of screws 16. A shaft 17 is mounted inthe openings of the plates 12 and 15 which form bearings therefor., The innerend of the shaft is enlarged as at 18, and is provided with an interiorly threaded bore. This enlarged end is normally held in engagement with the plate 12 by means of a spring 19 mounted in the shaft between the under side of the said plate and a collar 20 secured on the shaft. The outer end of the shaft is provided with a Winged bead 21 to facilitate turning the same. v 4 A handle 22 for turning the cylinder is removably secured to the plate and is bent under the end of the shaft 17. This handle is mounted between guide pieces 23 and 24C formed on the said plate, and is secured in place bymeans of a screw 25 and washer 26. Then not in use the handle may be removed to facilitate carrying.
The operation of my improved auger is as follows:
The position of the opening is determined by the built-in pipe 27, the .end of which protrudes slightly outside the plaster 28 and vThe spring 19 holds the toothed edge of the cylinder in engagement with the ceiling and exerts an inward force thereon.
The
vturning of thecylinder is continued until the lathing is reached, whereupon the cake of =plaster will fall into the cylinder together with all dirt and crumbs created during the cutting operation. The opening cut is entirely smooth with no broken corners,`
amd the outlet box may be perfectly fitted therein.v My improveddevice may be used in 'a room without' the necessity for removing or covering expensive rugs or other furnishings, and for this reason will prove especially desirable when such work must be done during the occupancy of a building.
.. I have illustrated and described a preferred and satisfactoq7 form of my invention but -it is obvious that changes may be made therein and that the same may be used for various purposes, all Within the spirit and scope thereof as defined in the appended claim.
A cutting device for plaster Walls adapted to engage a fixture therein and comprising a rod provided with means for engaging saidfiXture and With a stop, a, rotary tubular cutter disposed on said rod and provided with an interior abutment and at its outer end with a cutting edge, an expansive spring disposed on said rod between said stop and 15 said abutment; and means for turning said tubular cutter.
In testimony, that I Claim the foregoing as my invention, I have signed my name in presence of two subscribing Witnesses.
