@uiten tu'ts @anni @fitte GEORGE W. BISHOP, OF STAMFORI), CONNECTICUT, ASSIGNOR TC VEEDER COLEGROVE, OF GREENWICH, CONNECTICUT.
Letters Patent No. 69,5313, dated October S, 1867; dntedated August 27, 1867.
IMPROVEMENT IN DRILLING MACHINES.
vTO ALL WIIOM I'l MAY CONCERN:
Be it known that I, GEORGE W. Bislror, of Stamford, Fairfield county, Connecticut, have invented a new and useful Improvement in Self-Feeding Drill-Presses; and I do hereby declare that the following is a full,
clear, and exact description of the same, reference beinghad to the accompanying drawing, which forms parl of this specification.
Figure 1 is a vertical section of one part of my invention, tak-en on the plane of the line .r fr, fig. 3.
Figure 2 isa vertical section of the other part, taken on the plane of the line y y, Re. 4.
Figure 3 is a transverse section, taken on the plane of the line ze, fig. 1.
Figure 4 is a plan view of fig. 2.
My invention consists in the combination, with a screw-rod and arbor, and a friction-wheel attached to the former, of a friction-clamp, so constructed and arranged that the cut of the drill may be regulated as desired. It further consists in the combination, with the bracket on which the metal to be operated upon is placed, of a cam-lever, so arranged that the said bracket may at all times be rigidly held, thereby obviating the shaekling of such part occurring in ordinary drills of this character. It further consists in the combination of a pivoted arm, on which the bed-plate for the metal to be operated upon rests, and the said plate with the supporting bracket of the apparatus.
Refer to figs. 1 and 3. A designates a bracket for supporting the working parts of the drill, and B a back plate, by which the bracket is secured to the post or other article which is to support it.
C is an arbor tapped with an internal screw-thread, into which is fitted to work a screw, D. The arbor C carries at its lower end a socket, a, into which the drilling-tool is fitted, and said arbor slides in and is steadied by bearings b c in respective arms X X of the bracket A. Motion is imparted to the arbor C by means of gearwheels E F, the former being fitted upon the arbor loosely, and beingvprovided with a pin, d, which slides in a groove cut longitudinally in the arbor; hence the arbor has a free longitudinal movement, and is actuated by said gear-wheel E, working into the wheel F, suitably mounted on a shaft, to which shaft the rotary motion is imparted by hand or other power, as may be desired.
The screw-rod l) carries a fixed friction-wheel, Gr, against which the hand may be pressed in order to rcgulate the cut'. The said .rod D is journalled at its top in a suitable journal-box, I-I, let into an arm, X, of the bracket A, said box passing through said arm, and held in position by a nut, e, working on a screw-thread cut upon its top. .The said screw-rod Dis provided with a collar,f, which rests in a socket in the lower end of said journal-box II. Next this collar a groove is cut, around the screw-rod, of a proper size to receive the jaws of a frietionlamp, I I, Awhich in the presentginstance is hung upon a pin, y, extending from the arm X on one side ofthe screw-'rod and it is steadied b a in h extcndinc from an arm X on the other side. The frie- 7 p 7 7 C) 3 tion of this clamp upon the screw-rod is regulated by a thumb-screw, a, as shown clearly in iig. 3.
It will be seen from the foregoing description that the cut of the tool can be regulated as desired by merely regulating the friction of the clump upon the screw-rod, it of course being understood that the greater the friction the slower the said screw-rod turns, and consequently'thc tool makes deeper cuts, whilst, on the other hand, if the friction be considerably removed, the tool will make very shallow cuts; hence the drill, when once prperly adjusted to its work, needs no watching; it operates automatically. It will also be seen that the wheel G serves two important functions. First, after the clamp I has been set se as to regulate the cut of the tool as required for the greater part of the metal to be operated upon, it may become necessary, just for an instant or so, to apply a little more friction, so as to cause the tool to make a few deeper cuts, and run slower. This can be accomplished by merely applying the hand at such times against the wheel G, the friction thus caused retarding the revolution of the wheel Cr. On accountV of the fact that friction may be applied to the wheel G to regulate to a finer degree the frictionl already applied to the screw-rod by the clamp I, I have called the said wheel throughout this specification a friction-wheel. Second, the said wheel G also serves to run the arbor upon the screw-rod 'in an easy and expeditious manner as -will appear obvious from a glance at iig. I of the drawing. The advantages of such an apparatus are tee apparent-to need recital.
I will here remark that I do not limit myself te the style et' clamp here shown. My object is t0 apply te canna the screw-rod a friction-clamp or other device in such manner that the revolution ofthe screw-rod maybe regulated as desired.
llefer to figs. 2 and 4. J is a bracket fitted to rest against a back plate, K, by which it is secured to the post or other place. rlhe back plate K has a rib, if, cast on its face, and a corresponding groove, j, is formi-l in the vertical faces ofthe bracket, by which means the bracket is steadied when movingr it up and down. 'lhe said back plate has a slot, cut longitudinally through the rib lc for a certain distance, through which a pin. m. passes, whose end passes through the said braeket,it.\head sliding inthe recess at the hack ol` the gi'oove. linholes n are made, at short distances apart, through tht remaining portion of the rib, into which a pin, n, which passes through the lower end of' the bracket, is thrust, to steady the said bracket in place. In many machinesl of this class the bracket is not susceptible of bein r secured rigidly to the back plate, on account of the fact 'that it has to be arranged so as to be movable at pleasure. to regulate the distance of' the work from the drill. To prevent the shackling of the bracket, usually occurring, I secure to the end ofthe pin 112 a. lever, l, havin;r a cam-shaped end, and so arrange it that by depressing: the lever the bracket will be forced up close to the hack plate and there remain rigidly until further adjustment is necessary.
L is an arm, pivoted to the horizontal face of the bracket in `such manner that its forward end may be swung in either direction. Upon the end ofthe arm the bed-plate M for the work rests. In the present instance the said plate M is provided with a hollow `journal or trunnion, which fits into a hole made in the end ofthe arm L. This permits of the plate being revolved. It will be seen that should it be desired to drill a number of holes in a piece of' metal, the work can be done without shifting the piece. by merely moving,r the arm l. .sulliA ciently far in a lateral direction, and revolving the plutehl so :is to bring the exact Spot :it which the hole is lo be drilled under the tool. lf the drill is cuttingr a hole over the centre of the plate the latter and the arm muy both be pinned fast by a pin, j), passing through them and through a hole in the horizontal nrln of thtl bracket.
Some :f the advantages of this invention may be briefly stated to be, first, the depth of the cut nl' thv onl maybe accurately regulated, and when regulated no further manipulation is required, thereby producing :t sell'- feedingr drill; second. the bracket, which in many machines is shackling. thereby producing had wolk is held securely against its back plate; third, a hole may be bored anywhert` in the stall', without the necessity nl' changing its position on thc bed-plate, by merely refolrinj,r the said bed-plate and moving the arm i.| :t lateral direction, so as to brinfcr the spot to be drilled directly under the lool. These are important improvementsl which my invention provides.
What I claim :is my invention. and desire to secure by Letters l'atenl, n
1. The combination of the arbor C, screw-rod ll, wht-el (i. :ind friction-clutch I, arranged and operating a herein shown and described.
2. The combination of the caurlever l with the bracket d, perforated buck plate K, and ninsn and substantially as and for the purpose herein speeied.
3. The combination of the arm L and plate `;\l with the bracket d. comtrnett-u and arranged substantially as and for the purpose specified.
