This lathe was likely made by Lodge & Shipley of Cincinnati.
I claim, as my invention:
1. In a lathe, the combination, substantially as set forth, of a chuck having an annular T slotted rim projecting inwardly toward the tail-stock beyond the end of the lathe-arbor, and clamp-bolts engaging said slot.
2. In a lathe, the combination, substantially as set forth, of a saddle, a tool-rest, a cross feed screw journaled in the tool rest, a nut for said screw fitted for endwise motion in So the saddle, a form-plate secured to the slide way on which the saddle moves, and a lever pivoted to the saddle and engaging said nut and form-plate.
3. In a lathe, the combination, substantially as set forth, of a saddle, a tool-rest, a cross feed screw journaled in the tool-rest, a nut for said screw fitted for endwise motion in the saddle, a form-plate secured to the slideway on which the saddle moves, a lever pivoted to the saddle and engaging said nut and form plate, and a locking device, as a pin, to prevent the movement of said lever on its pivot.
4. In a lathe, the combination, substantially as set forth, of an annularly slotted tool-rest, a turret thereon, tool-clamping bolts diametrically arranged in and engaging the slot of the tool-rest and passing through the turret, and a pair of tools resting on the turret and straddling said bolts.
5. The combination, substantially as set forth, of a bed with two rails, a feed screw in each rail, a driving-shaft extending the length of the bed, gearing connecting said shaft with the lathe-arbor, a cross-shaft geared to the two rail-screws, a shaft parallel with said driving shaft and geared to said cross-shaft, and aligned pulleys on said driving-shaft and parallel shaft.
6. In a lathe, the combination, substantially no as set forth, of substantially a V-shaped tail slide provided with a pair of longitudinal T slots disposed at an angle to each other and a tool-holder bolted thereto.
7. In a lathe, the combination, substantially as set forth, of a tail-slide provided with a pair of longitudinal T-slots disposed at an angle to each other, and a bushing-holder and tool-holder bolted thereto.
8. The combination, substantially as set forth, of a T-slotted slide, a tool-holder thereon, a tool having an upward projection at its heel, a tool-clamp over the tool, a bolt passing through said clamp and tool-holder and engaging the slot of the slide, and a pair of set-screws carried by the tool-holder and engaging the opposite faces of the said tool-projection.
9. In a lathe, the combination, substantially as set forth, of a socketed cross-girt in the bed of the lathe, a shanked rest having a vertical movement carried by such socket, and a rest-piece fitted to slide horizontally in such shanked rest.
10. In a lathe, the combination, substantially as set forth, of a taper mandrel-socket in the inner end of the lathe-arbor, a mandrel adapted to fit said socket, and an axially disposed holding bolt connected directly to said mandrel, and a tail-slide, and a bushing-holder bolted to the tail-slide.
11. In a lathe, the combination, substantially as set forth, of a hollow lathe-arbor, having an axial bearing throughout the same, a tail-slide, and a holder bolted to said tail-slide and adapted to carry the tail end of a boring bar while its head end slides in the lathe-arbor.
12. The combination, substantially as set forth, of a threaded arbor, a nut screwed thereon and radially tapped for a set-screw, a plug in the set-screw hole with its inner end formed to correspond with the threads of the arbor, and a set-screw in the collar bearing on the outer end of said plug. |
