DRILL ATTACHMENT Filed June 7. 1928 2 Sheets-Sheet 2 1L raihf/* f 50 v wbb/Leos @nome/13o Patented Mar. 18, 1930 CLARENCE D. FOWLER, OF BAR HARBOR, MAINE DRILL ATTACHMENT Application led .Tune 7,
The invention aims to provide a novel and efficient attachment for well known forms of motor-driven, portable drills, of such nature that the axis of the drill or other part to be rotated, may be disposed at an angle to the axis of the usual drill chuck, thus enabling operation of the drill underfconditions with which the ordinary drill as now constructed, cannot cope.
Drills of the type to which I have referred, are commonly provided with a jaw chuck for gripping a drill or the like, and jaw-contracting and releasing means are provided, exposed at the periphery of the chuck, being usually operable by means of a key. It is a further aim of the invention to provide an attachment of such nature that the drive shaft thereof may be held and driven by the above-named jaw chuck, the carrying body for said shaft and an additional shaft driven thereby, being of such form as to give access to the periphery of the chuck for operating said jaw-contracting and releasing means when either applying the attachment to the drill or detaching it therefrom.
Another feature common to most drills of the type herein referred to, is an outstanding bearing boss at one end of the drill body or motor, and it is another object of my invention to provide the attachment with new and improved means contractible about said bearing boss for rigidly securing the body of the attachment to the drill body or motor.
Yet another aim is to provide a construction which, while being rather simple and inexpensive, will be efficient, reliable and generally desirable.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.
Fig. 1 is a side elevation of a portable electric drill and the attachment connected therewith.
Fig. 2 is a side elevation of the attachment removed from the drill, looking at right angles to Fig. l.
Fig. 3 is an end elevation of the attach- 50 ment, partly broken away.
1928. Serial No. 283,716.
Fig. 4 is a longitudinal sectional View on the plane indicated by line 4 4; of Fig. 2, showing the manner in which the attachment is secured to the bearing boss of the drill body and the way in which the drive shaft of said attachment is held in the conventional jaw chuck of the drill, illustrating also the opening in the attachment through which the chuck-operating key may be inserted.
Figs. 5 and 6 a're detail sectional views on rhe porrespondingly numbered lines of Fig. 7 is a sectional view on the plane of linev77 of Fig. 4, but omitting the conventional parts of portable drill shown in said figure.
Fig. 8 is a'perspective view of a cap which is instrumental in mounting shafts and gearing hereinafter described.
In the drawings above briefly described, D denotes the motor or body of a portable motor-driven drill, said body being provided with the usual outstanding bearing boss B and with a jaw chuck C at the outer end of this boss. The jaws of the chuck are indicated at J and the usual contracting and releasing means are provided for these jaws, said means having a socket S at the periphery of the chuck, engageable with a key K, so that operation of this key will either contract the jaws J or will release these jaws, as desired.
The attachment constituting the gist of the present invention is usable in connection with drills of the general type so far briefly described, and while the details of construction which I have illustrated in connection with said attachment are preferably followed, it is to be understood that within the scope of the invention as claimed, variations may be made.
I provide an auxiliary body A for attachment to the drill body D, said auxiliary body embodying a cylindrical head 10 and a tubular member 11 having one of its ends integral with one end of said head, the free end of said tubular member 11 being provided with means, hereinafter described, whereby it may be contracted around the bearing boss B to rigidly secure the attachment A to the drill body D, thereby holding the head 10 in outwardly spaced relation with the chuck C and in axial alinement with this chuck.
To relieve the screws 15 of excessive strain,
l the body 10 is provided with outwardly projecting studs 22 received in sockets 23 in the inner side of the cap 14. In the resent showing, these studs are provided lby the outer ends of sleeves 24 which are threaded into openings in thehead 10, and into these sleeves, the screws 15 are threaded.
In the present showing, one end of the shaft 17 carries a chuck 25 for a drill or the like 26, and the other end of said shaft is provided with another chuck 27 for engagement with nuts or the heads of stud bolts or cap screws. When nuts or the like are to be driven in one direction, the several parts bear the relation shown in the drawings. When they are to be turned in the other direction, the cap 14 is detached and the shaft 17 is turned end for end, the cap being then re-applied. Thus, proper directional turning of the shaft 17 may be obtained to either apply or remove nuts or the like, as occasion may demand.
At its free end, substantially half of the circumference, (28) of the tubular member 11, is separate' from the remainder of such circumference (29), providing relatively movable and fixed clamping members for engagement with the bearing boss B. These clamping members are provided with laterally. projectinglugs 30 with which clamping bolts or the like 31 are engaged. Thus,.the free end of the member 11 may betightly clamped around the boss B or may be easily detached from said boss as occasion may deman are related as shown in Figs. 1 and 4, and l purpose of effecting contraction of the jaws J around the drive shaft 13. This having been done, the sleeve 11 may be turned into desired relation with the drill body D, whereupon tightening of the bolts or the like 31 will rmly secure the auxiliary body A to the drill body, the attachment being then in readiness for use.
When the attachment is to be removed from the drill, the bolts 31 are first loosened, permitting the sleeve 11 to be turned to such a position as to allow insertion of the key K to release the jaws J, and upon suchkrelease, the auxiliary body A may be readily withdrawn from the drill.
As above explained, while the details herein disclosed are preferable, variations may be made within the scope of the invention as claimed.
I claim A drill attachment comprising a cylindrical head having an axial bore, a cap secured against one end of said head and having a bearing opening alined with said bore, a drive shaft rotatably mounted in said bore and said opening and projecting from the other end of said head for engagement with a drill chuck, a second shaft transverse to said drive shaft, gearing connecting the two shafts, said head and cap being jointly recessed to receive said gearing and to provide bearings for said second shaft, and a tubular member integral with said other end of said head, disposed around said drive shaft and projecting beyond the latter, the free end of j said tubular member having means whereby it may be contracted around a portion of a drill body.
In testimony whereof I have hereunto affixed my signature.
CLARENCE D. FOWLER.
Between its ends, the tubular member 11 is formed with an opening 32 for giving accessI to the periphery of the chuckC, for the purpose o operating the l jaw-contracting and releasing means.
