'YTAPPING AND DRILLING MACHINE.
. SPECIFICATION forming part of Letters Patent No. 760,878, dated m 24,, 1904. I
Application filed April 23, 1903.
To all whom it may concern:
Be it known that I, FERDINAND KOIIOUT, a citizen of the United States, residing in the city of St.-Louis, in the State of'Missouri, have invented certain new and useful. 1m provements in Universal Tapping and Drilling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to an effectiveand sim ple machine for drilling and tapping holes.
My invention consists in features of novelty hereinafter'fully described, and pointed outin the claims.
Figure I is a side view, part in section, illustrating my improved tapping and drilling machine. Fig. II is a vertical transverse section taken on lineII II, Fig. I.
Referring to the drawings, 1 represents a suitable framework in which is journaled a shaft 2, adapted to carry a drill 3 at one end and aftap-holding chuck 4 at the other end.
.The shaft 2 passes through journal-studs 5,
carried by the frame 1. These studs support beveled pinions orv wheels 6 and 7, with which mesh a beveled pinion or wheel 8, secured to the lower end of a vertical shaft 9. The shaft 9 may be turned either by a drill-press (not shown) applied to its upper end 'or by means of a counter-shaft 10, provided with apulley 11 and which has a bevel-gear connection 12' with the shaft 9. As the shaft 9 is turned it will cause one ofthe beveled pinions 6 7 to be turned to the right and the other one to be turned to the left thesepinions revolving constantly so long as the shaft 9 is being turned. Keyed or otherwise secured to the shaft 2 between the beveled pinions 6 and 7 is a clutch 13, adapted to engage with either the beveled pinion 6 or the beveled pinion 7 according to which position it is in. I have shown the clutch in the form of a collar having pins on itsopposite faces adapted to en'- gage with pins projecting, respectively, from the faces of the beveled pinions 6 and 7.
Surrounding the shaft 2, between the clutch 13 and the beveled pinion 6, is an expansionspring 14, which in the absence of endwise automatic in its operation.
Serial No. 153,923. (No'modeL) ip'ressure on the shaft holds the clutch 13 into engagement with the beveled pinion 7 and '.when the parts are in this position the drill 3 .is being turned to the left or in theproper direction to drill a hole in a piece of metal placed between the drill-point and the rest 15.
When the hole has been drilled, the piece of' metal is moved to the chuck end of the shaft, and when pressure is applied that causes the metal to be forced'against the tap (not shown) thespring 14 contracts, permitting the endwise movement of the shaft 2 in the direction of the arrow and causing the clutch 13 to engage with the beveled pinion 6. This causes the shaft 2 to be turned to the right or in the proper direction for tapping a hole in the piece of metal that has been=drilled. When the thread has been formed and the pressure is removed from behind the piece of metal, the spring 14 throws the shaft 2 back to the position shown in Fig. I, so that the clutch 13 will engage the beveled pinion 7, and the shaft now commences to turn to the left, thus unscrewing the tap and causing the drill-point 3 to form-another hole in a piece of metal which has been placed in front of it against the rest 15. In this way the time of the machine is fully utilized, and it'is entirely The perfect alinement of the shaft 2, the drill-point 3, and the tap carried by the chuck ,4 reduces the danger of breaking drill-points and taps to a mini mum.
The rest 15 is carried by a common form of slide mechanism. 17, and when a hole has been tapped the movement of the rest 15 toward the drill 3 with the interposed piece of metal to be drilled acts to assist the spring 14 to move the shaft to and bring the clutch into engagement with the beveled pinion 7.
I claimas my invention 1. In a tapping and drilling machine, the combination of a suitable frame, a shaft loosely journaled in the frame adapted to move endwise therein and provided at one end with means for carrying a drill and at the other end with means for carrying a tap, a pair of pinions, means for moving the pinions in opposite directions, and a clutch connected to said shaft and which is adapted to engage either one of said pinions according to the position of the shaft, substantially as set forth.
2. In a tapping and drilling machine, the combination of a suitable frame, a shaft loosely journaled in the frame adapted to move endwise therein and provided at one end with means for carrying a drill and at the other end with means for carrying a tap, a pair of pinions, 'a driving-shaft geared to said pinions and adapted to move the same in opposite directions and a clutch connected to the first-mentioned shaft and which is adapted to engage either one of said pinions according tothe position of its shaft, substantially as set forth.
3. In a tapping and drilling machine, the combination of a suitable frame, a shaft loosely journaled in thevframe adapted to move endwise therein and provided at one end with means for carrying a drill and at the other end with means for carrying a tap,
a pair of pinions journaled to said frame around said shaft, means for moving the p1n ions in opposite directions, a clutch secured to said shaft and which is adapted to engage either one of said'pinions according to the position of the shaft, and a spring for exerting endwise pressure to said shaft in one direction, substantially as set forth.
4. In a tapping and drilling machine, the combination of a suitable frame, a shaft loosely journaled in the frame adapted to move endwise therein and provided at one end with means for carrying a drill and at the other end with means for carrying a tap, a pair of pinions journaled to said frame around said shaft, a driving-shaft geared to said pinions and adapted to move the same in opposite directions, a clutch secured to the first-mentioned shaft and which is adapted to engage either one of said pinions according to the position of its shaft, and aspring for exerting endwise pressure on the first-mentioned shaft in one direction, substantially as set forth.
