Specification of Letters Patent.
Patented Nov. 26, 1912.
Application filed March 8, 1910. Serial No. 548,071.
To all whom it may concern:
Be it known that I, ARTHUR SWAINSON- BROOKE, a subject of the King of Great Britain, residing at A7 Cartwright street, Doncaster, in the county of York, England, have invented certain new and useful Improvements in and Relating to Drill-Jigs, of which the following is a specification.
This invention relates to drill jigs and has for its chief object to provide a jig which will give a quick, accurate and secure positioning of the work under the drilling machine. The invention is more particularly intended for use in connection with the drilling of pin holes in bolts, studs, pins, and similar parallel work.
According to this invention, the jig comprises t-wo superposed V blocks of different sizes, and a cross-beam adapted to receive bushes to suit the size of the drill employed, the said cross-beam also serving to clamp the work to be drilled, to one or the other of the V-blocks. The said V blocks and the cross-beam are capable of relative movement in a longitudinal direction 2'. e. in the direction of the grooves in the V blocks. A scale is provided either on a fixed or a movable part of the jig, so that the relative positions of the cross beam and the V blocks can be quickly altered to any desired position, suitable clamping means being provided for holding the cross-beam securely on the work to be drilled and for retaining the parts in their adjusted position.
In order that my said invention may be clearly understood and readily carried into effect, I will describe the same more fully with reference to the accompanying drawings, in which Figure 1 is a perspective view illustrating one constructional form of my invention and showing a bolt in position to be drilled. Fig. 2 is a perspective view illustrating a modified construction. Fig. 3 is a similar view showing the device adapted for use with comparatively large work. Fig. 4, is a front elevation on an enlarged scale, of Fig. 2 showing more clearly the details of construction. Fig. 5 is an end elevation also on an enlarged scale, of Fig. 4, and Fig. 6 is a cross section showing the construction of the lower V block of the modification illustrated in Figs. 2 to 5.
In all these figures A representsthe base plate and A the lugs by means of which it is bolted to the table of the drilling machine, B is the aforesaid cross beam, C the square spindle disposed in the slot D, and E is the scale.
Referring more particularly to Fig. l, a is the large V groove formed in the top of the base plate A, the said groove serving for the reception of the V block a having a small V groove (1 formed therein. The said V block a is retained in position by 'means of a key a". a which is used as an abutment for the work during thedrilling operation when the work is unprovided with a head or collar to bear against the end of the V blocks as shown in the drawing; the key a is also used for this purpose when the lower V block only is employed. The aforesaid square spindle C is provided at one end with a head (not shown) and is screw threaded at the other end to receive a wing nut 0 or the like. A block C is loosely mounted on this end of the spindle C, and this block and the head of said spindle carry pillars C" C which receive the aforesaid cross beam B. The said pillars are provided with spiral springs to support the cross beam clear of the work when the cross beam is released and the cross beam is retained in position by means of two nuts 0 0' screwed on the upper ends of the pillars C", one (0*) being a wing nut.
to allow of the work being more readily clamped and unclamped. The scale E is so placed that the distance of the drill from the end of the V block a can be readily seen. On the longitudinal center and to the right of the transverse center the cross beam B is formed with a hole for the reception of a bush B of hardened steel. Bushes having various sized holes are provided to suit drills of difierent diameters.
Referring to the construction shown by Figs. 2 to 6 of the drawings, the large V groove a is formed in a block A movable with respect to the base plate A. The upper V block a is as in the construction described The V groove a is provided with a stop and the head (1 of the spindle G are provided with projections c, 0, (Figs. 4 and 5) which fit in holes formed in lugs 0 0 on the base plate A, the said projections being retained in position by means of pins 0.
The inner surfaces of the block C? and the head 0 are adapted to fit in grooves a a (Fig. 6) formed in the sides of the lower V block A; when the wing nut 0 is tightened up on the spindle C the said block C and the head (1 retain the t blocks in position in rigid connection with the base plate. The base plateis provided with a pin A (Figs. 4 and 5) which is adapted to fit in the usual central hole in the table of drilling machines, of the kind in which a smooth ta leis provided, (2'. 0. one in which no holes orchannels are provided for bolting work thereon); as the axes of the bush B and the said pin are in aline1nent,this provides a quick means of bringing the center of the bush into line with the drill. It will be observed that in this construction when once the base plate has been laced or secured on the table in such a position that the drill and the hole in the bush are in alinement, no "movement of the cross beam B takes place when the necessary adjustments for various lengths of'work to be drilled are made, and as soon as the-V block A has been moved to the desired extent, and the nut c has been tightened, and the nuts c", c adjust-ed, the jig is in order to receive work for the drilling operation to be performed once. A pointer e for the scale E is fixed to the lug 0 What I claim and desire to secure by Letters Patent of the United States is 1.. In a jig for use with drilling machines, the combination with a work sup porting block having a longitudinal slot therein, of a spindle disposed in said slot, a cross beam for clamping the work on the aforesaid block, means connecting the spindle with the cross beam and means for retaining the spindle at any desired position in the length of the said slot.
