ADJUSTABLE TOOL-REST.
SPECIFICATION forming part of Letters Patent No. 470,010, dated March 1, 1892.
Application filed June 11, 1891. Serial No. 395,855. (No model.)
To all whom it may concern.-
Be it known that I, LEVERETT E. RHODES, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Adjustable Tool- Rests, of which the followingis aspecification.
This invention relates to adjustable tool posts or rests for lathes, the object being to provide a tool-holding rest constructed for holding the tool at various angles to the axis of the work and to be rigidly clamped without varying the position thereof.
In the drawings accompanying and forming a part of this specification, Figure 1 is a plan view of a tool-rest embodying my invention. Fig. 2 is a side elevation, and Fig. 3 a front elevation, of the same. Fig. 4 is a vertical section in line Ct to of Fig. 2 as seen from the left hand of said figure. Fig. 5 is a central vertical section, the View being taken in line Z; Z) of Fig. 1 and a tool-holder and tool being shown in place on the rest.
Similar characters designate like parts in all the figures.
As shown in the accompanying drawings, my improved rocking tool-rest consists of the base or slide B, adapted to be attached in the usual manner to the tool-carriage of a lathe or like machine, and a rocking bed or rest properly located on said bed and constructed for carrying the usual tool-holder II in a wellk-nown manner. The base or slide B is provided with the guides 2 and 4, by means of which it is gibbed to and guided in its movements on the usual carriage. The sides of the slide are constructed to form a pair of ears 3 and 5, between which is the mortise 6 for receiving the depending part 7 of the rest 0. Said part '7 closely fits the mortise 6 between the ears 3 and 5 and is pivoted on a pivot-pin S, which passes through the said ears and the lugs 7, thus connecting together said rest 0 and the base. The ear 3 is bored to allow the binding-screw 10 to freely pass through it, and the ear 5 is bored and tapped to receive the threadedend of said screw. An elongated slot or opening 12 is suitably formed in the bed C, to permit of the free movement of the bed C on its pivot 8 when this is desired, and also to firmly clamp together the said bed and the base B by forcibly springing the said ears onto the sides of thelug 7. The side walls or ears 3 and 5 are concentric on their upper edges to the pivot 8 and are let into the sides of the rest C, as will be understood by comparison of Figs. 1, 2, 3, and 4, so that said rest bears directly on the top of said side walls, which thus receive the pressure due to supporting the tool to its work. The projections or walls 14: and 16 of the base B are bored to receive the pivot-pin 18, on which pin between the said walls is supported the nut 17. A boss or projection 20, formed on the rearward end of the rest C, has a recess 22 formed in the under side thereof to receive the upper projecting end 21 of the nut 17. Said projection is bored to permit of the free passage through it of the adjusting-screw '24:, and is spherically countersunk to receive the collar 25 of said screw. Below the web 26, that is thus formed in said projection 20 between the said spherical countersink and the recess v 22, a check-nut 27 is fixed on the screw 24, to serve as a collar, the under side of said web 26 being convex in form and the contiguous face of the nut 27 being shaped to nicely fit the same. \Vhen thus constructed and fitted up, the device constitutes ajoint, permitting of the required lateral orswingingmovement of the screw The projecting end 21 of the part 17 is bored and tapped to receive the screw 24, which is fitted to turn closely therein, so that the operator by applying a Wrench to the squared head of said screw is enabled to adjust'the rest Con its pivot, as may be required. Said rest has or may have a pair of T- slots 28 and 30 wherein to receive the usual tool-holder H, carrying the cutting-tool T, which rests on the collar 32, all in a wellknown manner.
In using the rest the operator first turns the screw 10 to unclamp the ears 3 and 5 from the depending lug 7 of the rest C, next turns the screw 24 to swing the rest on its pivot and bring the tool to its required position, and then reclamps the rest by firmly screwing up the said binding-screw.
The improved tool-rest herein described is especially adapted for use on lathes having the so-called gibbed carriages.
Having thus described my invention, Iv
claim- 1. In a tool-rest, the combination, with the base having the upwardly-projecting side walls forming ears concentric to the axis of the adjustable rest and carrying the pivot for said rest, of the rest pivoted between said side walls and fitted to the upper edges thereof, a binding-screw clam ping: and uuelamping the ears to and from the rest, and means for swinging the rest on its pivotwhen unclamped, substantially as described.
2. In a tool-rest, the combination, with the base having the ears 3 and 5 and carrying the pivot for the rest, of the rest G, pivotally supported on said pivot and closely fitting between said ears, a binding-screw, substantially as described, for clamping and unclamping the rest, the nut 17, pivotally supported on the base, and the adj usting-serew connected,
substantially as described, to the rest and fitting said nut, substantially as described.
3. In a tool-rest, the combination, with the base having the upwardlyprojecting side walls forming ears concentric to the axis of the adjustable rest and carrying the pivotpin 8 for said rest, of the rest 0, carried by said pivot-pin and closely fitting between said ears and having the slot 12, and the clampscrew 10, passing through said ears and slot, whereby the rest may be clamped and unclamped, substantially as shown.
