JAMES rownns, or NEW YORK, N. Y.

TRANSFERRING MASTER-DRILL DEVICE.

Specification of Letters l'atent, Patented J 1y 15, 1919,

Application filed June 6, 1917. Serial No. 173,093.

To all whom it may concern Be it known that 1, JAMES Pownns, a citizen of theUnited States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Transferring Master-Drill Devices, of which the following is a specification.

This invention relates to transferring or profiling machines or devices and more particularly to master transferring devices for drills and other similar machine tools.

()ne object of this invention is to provide a machine of this kind which is simple and economical in construction, efficient in oper-. ation and easy to manipulate.

Another object is to provide convenient forms of tables for positioning guide plugs or pins for positioning the drill or similar tool.

Another object is to provide a convenient means for changing from one kind of drill or tool to another without removing them from their chucks or holders.

These and other objects will appear as the description proceeds; and it is understood that the invention is not limited to the particular constructions described since these may be greatly varied without departing from the scope of the appended claims.

In the accompanying drawings showing, by way of example, several of many possible embodiments of the invention,-

Figure 1 is a front elevation of the machine;

Fig. 2 is a side elevation, partly in section; Fig. 3 is a plan;

Fig. 4 is a perspective view of one form of positioning table;

Fig. 5 is a perspective view of a positioning plug adapted to be secured to the table of Fig. 6 is a perspective view of the adjustable support for the pilot spindle, the drill or tool spindle and the driving means for the drill or other tool;

Fig. 7 is a perspective view of another form of positioning table; 1

Fig. 8 is a perspective view of a positioning pin adapted to be secured on the table of Fig.

The column 10 forming the frame of the machine is provided with a lateral bracket 11 on which is secured the ositioning table 12.

On the front face of t e column 10 is provided a vertically extending dovetailed guide on which is adjustably received the grooved tool or work knee or table 14 held in adjusted position by means of the screw clamps 15.

The upper part of the column 10 is carried upwardly and rearwardly to form an extension 16 (Fig. 2) in which is slidably carried the V-shaped supporting arm 18 adapted to be locked in place by the lock clamps 17 and to be slidably moved by the pinion 19 rotated by the handle 20 and engaging the rack 21 secured to the edge of the supportin arm 18.

The forward end of the supporting arm 18 carries transversely thereto the horizontal support 22 on which are mounted gibs 23 forming a 'slideway in which is carried. a slide 24 adapted to be locked therein by the screw lock 25 and to be horizontally moved therein by means of the small pinion 26 engaging a rack 27 secured to the lower part of the slide.

On the front face of the end of the slide 24 over the tool knee 14, there is secured a bracket head 28 in which vertically slides the spindle sleeve 29 provided at its rear part with a vertical rack 30 engaged by a suitable pinion (not shown) controlled by the handle 31, whereby the spindle sleeve is raised and lowered.

Rotatable within the sleeve 29 is a drill chuck spindle 32 carrying at its lower end a chuck 34 for the drill 35 or other tool. The upper part of the spindle 32 is provided with the usual longitudinal key way in which engages a key fixed in the bore of the helical gear 36 carried between, the bearing arms 38 connected'by the yoke 39 provided with a bearing base receiving the drive shaft 40 carried in the bracket-bearings 41 mounted on the support 22. Y

The shaft 40 is provided with a key-way 42 adapted to receive the key 43 of a helical gear 44 engaging the Worm gear 36 and-slidable on the drive shaft 40 and constrained by said key and key-way to rotate therewith.

On the inner end of the drive shaft 40 there is secured "a bevel gear 45 engaged by the driving bevel gear 46 mounted on the end of the countershaft 48. carried by the bracket- bearings 49 and 50 mounted respectively on the horizontal support 22 and when desired.

on a plate 51 secured on top of the extension 16. a

A motor 52 mounted on a plate 54 secured to the top of arm 18 is provided with a motor shaft 55 carrying a pulley cone 56 from which power is transmitted by means of the belt 58 to the pulley cone 59 mounted on the countershaft 48.

On the end-of the slide 24 over the'positioning table 12 is disposed the supporting bracket 60 in which is vertically slidably mounted the pilot spindle 61 provided at its rear part with a rack 62 engaged by a pinion controlled by the handle 64, whereby the pilot spindle-may be raised and lowered.

On the lower end of the pilot spindle is formed a chuck 65 adapted to receive the shank of a guide 66 held in place by a set screw 68 and provided with a guide base 69 in the lower end thereof.

The positioning table 12 is secured to the lateral bracket 11 by means of screws 70 and 71, the screws 71 serving also to se-' cure on the table the locating scales 72 which serve for locating and squaring the patterns or guides upon the table.

The locating table 12 is provided with a plurality of intersecting T-grooves 74, the under cut portions 75 of which are adapted to receive the head 76 of the threaded pin 78, F1g. 5,;passing through the guide sleeve 79 and receiving thereon the milled nut 80 Which coiigerates with the head 76 to clamp the sleeve 9 to the positioning table, where by s formed a guiding lug adapted to be rece1ved 1n the guide bore 69 and thus position the guide 66 and pilot spindle 61 and consequently the drill spindle 32 and the drill 35 or other tool.

It is noted that the base of the sleeve 79 is much larger than the threaded pin 78, whereby it is possible to set the sleeve ,eccentrically of the threaded pin and therefore possible to fix the sleeve considerably to one side or the other of the groove 74,

The operation of the machine scribed is as follows:

The work knee is suitably-adjusted and the work piece properly adjusted thereon,

and the guide sleeve or sleeves 79 are secured at points corresponding to where holes are to be bored in the work piece. The arm 18 and the slide 24 are then moved by means of their 'rack and pinions until the bore 69 s over the sleeve 79, and the then lowered until the bore 69 fits upon the sleeve 79 and the arms 18.

The support 24 is locked in this position,

so far de- .working rotation after which the drill spindle 32 and with it the drill are lowered by means of the handle 31, whereupon a hole is drilled in the work piece, the drill being driven by the motor 52 by means of the connections herebefore described.

The operation just described is then repeated for each sleeve 79 fixed to the positioning table.

Instead of the sleeves 79 being fixed to the positioning table a pattern may be substituted, and a profiling tool and a pilot pin may be substituted for the drill 35 and the guide 66 respectively, and a profile of the pattern produced on the work piece as is well known.

Also it is obvious that a drawing may be placed on the bracket 11 and the details thereof traced with a scriber substituted for the guide 66, whereby the object shown by the drawing may be reproduced on the work piece by means of appropriate tools.

In Fig. 7, I show an alternative form of positioning table provided with securing screws 91 and a positioning scale 92 similar to those shown in connection with the table 12. Instead, however, of the T-slots, I provide a group of screw holes 94 adapted to receive the screw 95 passing through a slot 96 in one end of [the elongated plate 98 carrying fixed at the opposite end a positioning pin 99, the screw serving to fix the plate and therewith the pin 99 to the positioning table. The screw and slot connection serves to permit the fixing of the positioning pin in any position between any of the holes 94.

Obviously, when the pin 99 is used, the bore 69 in theguide 66 would be made to fit the pin.
