Description
STATES PATENT OFFICE. 1
WILLIAM MOUIITON, F WATERVLIET, NEW YORK.
' n'rrncnmnn'r non. DRILLS.
To all whom it may) concern:
Be it known that I, WILLIAM E. Morm- TON, a citizen of the United States, residing at Watervliet, in the county of Albany and State of New York, have invented new and useful-Improvements in Attachments for Drills, of which the following is a specification.
From experience I have found that bits, employed" in the ordinary construction of portable motor driven drills become very frequently broken, because the bit is not held at a direct right angle with respect to its work. As no means is provided upon such classes of drills for indicating the degree of angle at which the same enters its work, it is almost an impossibility to con tinuousl drill straight holes. Also rom experience I have found that by the employment of a gage in the nature of a s irit. level, or, more pmperly speaking, to ingedly connect spirit levels one movable ri ht angularly with respect to the other, tiat holes maybe drilled either vertically or horizontally at a direct right angle with respect to the work operated on, so that twisting the drill in an attempt vto direct the same, when the said drill has taken an indirect path will be entirely avoided and as a resulttrue holes may be easily drilled and danger of the breaking of the drills will be effectively overcome.
The object of the present invention is to produce a device of this character which shall be of an extremely simple construction,
any ordinary class, and which will perform the functions for which it is devised with accuracy and with certainty.
The foregoin objects, and others which will appear ast e nature of the invention is better understood, may be accomplishedby a simple construction, combination and operativeyarrangement of parts, such as illustrated by the accompanying drawings, 7
in which:
Figure 1 is a view illustrating a drill provided with the improvement.
Fig. 2 is a sectional view approximately on the line 2-2 of Fig. 1.
Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 2, and illustratlng the horizontal level in operative position.
The numeral 1 designates a pneumatic or other power drill, and 2 the bit therefor.
On the body of the drill is secured my Specification of Letters Patent.
improvement broadlyindicated by the numera'l 3. The improvement contemplates the employ'ment of a flat body member 4, haying'its edges provided with, hinged leaf portions 5, and these'leaf portions -are secured to the body of the'drill. By'providing the body of the improvement with the pivoted'leavesthe device may be attached to any (ordinary construction of drills, whether the bodies thereof are oval in cross section, square, rectangular or any other shape. The body 4 of the improvement, at one of the ends. thereof has an outwardly arranged right angular extension in the nature of a lug 6, the saidlug having a cen- Patented Mar. 9, 1920.; Application filed April 14,1919. Serial No, 289,177.
tral notch or cut-away portion 7 and having I a bore therethrough, and in this bore is arranged a spirit glass 8, .the bubble in the said glass being arranged in the notch 7 when the drill bit is held vertical.
On the inner and straight face of the lug -6 is hin'gedly connected, as at 9 a block 1.0.
This block is provided with a bore 11 within which is arranged a spirit bulb or glass 12. -The block, upon its outer face is provided with a notch or opening 13, and
through this opening the bubble in the glass or bulb is discernible when the block 10 is swung at a right angle with respect to as at 14 a prop member 15. The prop is designed to contact with the outer straight face of the'body 4 when the block 10 is ar, ranged right angularly with respect to the ally secured, upon the inner face thereof, which may be readily attached to drills of said bod and to be folded again st'the inner flat .ace of the block 10 when the block is swung against'the body 4. The'body 4 may be provided with a depression 16 to re celve the prop and the head of the pivot 14 when the block is swung against the body 4. From experience I have found that the weight of the block is sufiicient to retain the same against the body 4, but if desired suitable latch-ing means may be employed for this purpose, the latter being indicated by the dotted lines in Fig. 2 of the'drawings.
and designated by the numeral 18. i
It is thought, from the foregoing description, when taken in connection with the drawings, the simplicity of the construction and the advantages thereof will be readily 20 respect to the body.
I 2; In a device for the purpose set forth,
means on the edges thereof, a right angu-i larly lug disposed, on one of the endsof the body, said lug having an inner straight'face, aspiritgbulb in the lug, said lug having a central notch. communicating with the spirit bulb, a block hingedly secured to the inner face of the lug and designed to normally rest against the body, a spirit bulb in said block, said block, upon its outer face havin an opening communicating with the bulb, and a pivoted prop on the inner face of the block designed to contact with the body to hold the block at" a right angle with a fiat substantially' rectangular body member, hinged leaf members on the edges of the body and designed to be secured to a support, a right angularly disposed lug on one of the ends of the body having a bore therethrough and a central notch communicating with the bore, a spirit bulb in the bore, said lug having an inner straight face, a block hingedly connected to the inner face of the lug and designed to normally rest on the body, means for retaining the lug in said right angular position, a pivoted prop on the inner face of the block designed to be A swung against the body at a right angle with respect to the body, said block having a bore therein and having on its outer face an opening communicating with a bore, and
a spirit bulb in the bore.
In testimony whereof I WILLIAM EDWARD MOULTON.
