THOMAS JOHN DORAN, OF NEXV YORK, N. Y.
HAND-OPERATED DRILL.
SPECIFICATION forming part of Letters Patent No. 614,848, dated November 29, 1898.
Application filed February 11,1898. Serial No. 669,919. (No model.)
T 0 all whom it may concern:
Be it known that I, THOMAS JOHN DORAN, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Hand-Operated Drills, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to hand-operated drills, and has for its object to provide a support for such drills, which is. adapted to antomatically feed the drill in its work and return the same when the work of drilling is completed.
The invention consists of a supporting frame for drills constructed substantially as hereinafter described, and defined in the claims. The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same letters of reference in each of the views, and in which Figure 1 is afront elevation of the improved supporting-frame for drills. Fig. 2 is a side,
View thereof, and Fig. 3 is a View of a detail.
Referring to the drawings, Arepresents the base or support of the improved supportingframe for drills and is made, preferably, of metal and substantially rectangular in form. Supporting-standards A are secured to the said base, preferably by means of screwthreads, and at a point somewhat above the center of each standard is arranged a flange a, upon which rests a helical spring B, coiled about the standards A. The upper portion of the standards A is provided with screwthreads upon which are mounted threaded nuts a a and a helical spring B is coiled aboi it the standards A between the said nuts a a A drill-supporting rod D is loosely mounted upon the standards A and bears upon the upper ends of the springs B, and said rod is provided at its central point with a threaded opening d, which is adapted to receive aloinding-bolt d. An ordinary drill O is provided below the breastplate with slotted or diverging arms, between which the supporting-rod D is arranged and to which the said rod is removably secured by means of the bindingbolt d, which passes transversely through the supporting-rod D and through the arms of the slotted or spread portion of an ordinary drillstock which embraces said rod.
A pressure-bar E is loosely mounted upon the upper portion of the standards A and normally rests upon the lower nuts a. The lower ends of springs B bear upon the upper face of the said bar, whilethe upper ends of said spring engage the under side of the upper nuts a By changing the position of the lower nut a the position of the pressurebar E may be changed, and by changing the position of, the upper nut a the tension of the spring B may be regulated. An adjusting-screw rod F is threaded in the pressurebar E and is adapted to bear upon the breastplate of the drill to force the same to its work.
The lower springs B are principally for sustaining the weight of the drill and serve to retract the drill after the work of drilling is accomplished and the adjusting-rod F is disengaged from the breastplate of the drill.
The upper springs B are the compressingsprings and are considerably stronger than the lower springs B and serve to force the pressure-bar E downwardly against the drill G.
The base A is provided upon its under side with a longitudinal bar or rib A by which the frame may be secured in a vise or other suitable clamp.
In Fig. 3 is illustrated a modified form of base G, in which are provided threaded sockets g and a longitudinal slot g. The lower ends of the supporting-standards A are adapted to be screwed into the threaded sockets g and the base clamped to a'bench or other suitable support by means of a threaded bolt working in the slot g.
The drill O is secured to the supporting-rod D and is adapted to be advanced or retracted as required. The drill is then forced to its work by turning down the adj usting-screw F, as will be evident from the above description.
Having fully described my invention, I claim as new and desire to secure by Letters latent 1. In a drill-supporting frame, the combina tion with supporting-standards, a drill-sup porting rod mounted thereon and movable with relation thereto, a pressure-bar sleeved upon said standards above the supportingrod, means for sustaining said supporting-rod and governing the position thereof,and means for operating the pressure-bar, of a drill carried by the supporting-rod and adapted to be engaged by the pressure-bar, substantially as described.
2. In a drill-supporting frame, the combination with supporting-standards, a drill-supporting rod loosely mounted thereon, sustaining-springs sleeved upon said standards upon which said rod rests, a pressure-bar loosely sleeved upon said standards, compressionsprings mounted upon the standards and adapted to bear upon said pressure-bar, of a drillsecured to said supporting-rod and means connected with said pressure-bar adapted to engage the drill and force the same to its work, substantially as described.
3. In a drill-supporting frame, the co1nbination with supporting standards, threaded at their upper ends and provided with a suitable flange, sustaining-springs sleeved on said standards and bearing against said lugs, an upper and a lower nut screwed upon the threaded ends of said standards, a supporting-rod loosely mounted upon the standards and bearing against the sustaining-springs, a pressure-bar loosely sleeved upon said standards and adapted to bear upon the said lower nuts, compression-springs sleeved upon the standards and adapted to engage said pressure-bar,and an adj usting-screw rod threaded in said pressure-bar, of a drill secured to the said supporting-rod and adapted to be engaged by said adj listing-screw rod, substantially as described.
4. In a drill-supporting frame, the combination with a drill of supporting-standards, sustainin g-sprin gs sleeved thereon, a supportingrod bearing upon said spring and adapted to support said drill a pressure-bar loosely mounted upon the said standards and adapted to engage said drill, and compressionsprings of greater strength than said sustaining-springs adapted to bear upon said pres-- sure-bar, substantially as described.
In testimony that I claim the foregoing as inyinvention I have signed my name, in presence of the subscribing witnesses, this 8th day of February, 1898.
THOMAS JOHN DORAN. lVitnesses:
L. M. MULLER, M. A. KNoWLEs.
