ALBERT F. PRENTICE, OF WORCESTER, MASSACHUSETTS.
ENGINE-LATHE.
SPECIFICATION forming part of Letters Patent No. 593,607, dated November I6, 1897. Application tied May 12,189?. serial No. 636,161. cio man.)
To r/,ZZ w/tom t may concern,.-
Be it known that I, ALBERT F. PRENTICE, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Engine-Lathes,
' of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable per- 1o sons skilled in the art to which this invention appertains to make and use the same.
My present invention relates to an improvement in the hand feed appliances for compound tool-rests for engine-lathes, and more especially applicable to lathes in which a tailstock having a rearwardly-offset standard is employed, the object of my invention being to render the feed conveniently operative when the top shoe and guide of the compound 2o tool-rest is set at extreme positions of angularity, right or left, as for feeding the tool in a plane or direction more or less nearly parallel with the axial line of the lathe-spindle, in which position the end of the tool-rest slide,
y with its feed-screw, occupy a position close to or under the tail-stock or against the head of the lathe.
To this end my invention consists in combining with the slide or shoe which carries 3o the toolpost and the feedscrew spindle whereby said slide is operated a transverselydisposed arbor having ends fitted for receiving the removable wrench or handle-piece and a pair of spiral toothed gears connecting said i 3 arbor and feed-screw for operation, as hereinafter explained; also, in the combination,
in an engine-lathe, with a compound toolrest and a tail-stock having its standard rearwardly offset, of a lateral screw-operating de- 4o vice whereby the feed-screw for the' tool-post slide or top shoe of said compound tool-rest can be conveniently operated by hand when the end of said slide is closely adjacent to the offset standard or when swung to a position over the tail-stock, as more fully hereinafter explained.
In the drawings, Figure l is a plan view of a portion of an engine-lathe with compound tool-rest, illustrating my invention. Fig. 2
5o is a side view of the top shoe, its guide, and
feed-screw-operatin g mechanism. Fig. 3 is an end sectional view, and Fig. 4 a plan view showing my improvement.
In the drawings, A denotes the carriage, A the lower or cross slide, and a the upper guide or swing plate of the well-known compound tool-rest.
B indicates the top shoe or slide-plate, on which the tool-postrl is supported, and C indicates the feed or adjusting screw for mov- 6o ing the slide-plate B and tool-post along the guideway of the swing-plate a for feeding or moving the tool to its work. The neck of said screw turns in a bearing b, fixed to the slide B, and its thread engages with threads y in the plate ct.
In my invention I provide a short shaft or arbor D,'which I arrange above and transverse to the feed-screw C and mounted to turn inbearings @,attached to. the outer end 7o of the shoe or slide-plate. In the present instance and preferably the bearings are integrally attached, but may, if desired, be attached by screws or otherwise fixed to the plate. Upon the center of said arbor be- .75 tween the bearings e there is keyed a spiral toothed gear F, that engages or meshes with a similar intermatching spiral toothed gear E, fixed on the screw-spindle C, as shown. The arbor D is confined from endwise move- 8o ment in its bearing by the collar m and nut fn., that fit against the respective ends of the bearings, while the ends dand d of the arbor (one or both)gproject laterally from the plate and are formed similar to the eud d2 of the 85 screw C for receiving the removable turn-key, wrench, or handpiece II, by which the arbor or the screw can be "rotated for moving the tool support and slide on its guide -plate. The ends d, d', and d2 are preferablyprovided 9o with splines, as shown, for engaging a suitable groove in the interior of the handpiecesocket.
The top of the plate B between the bearings e is best made as a hollow shell-casting, as at b2, to form a protecting-housing for the spiraltoothed gear F and a neat nish for the eX- terior. v
Fig. l shows my improvement as employed on a lathe in combination with a tail-stock K, roo i having a rearwardly-offset supporting-standard or of the character described in Letters Patent No. 553,594, in Which the tail-stock standard rises from its base wholly in rear of the dotted line J, thereby allowing the'end of the shoe B to swing under the head or spindle-bearing of the tail-stock. In this connection it will be seen that the operator can place the handpiece on the laterally-projecting end d of the arbor and by the aid of said arbor and the spiral-toothed gears conveniently rotate the feed-screw from a front position in relation to the lathe. set tail-stock my invention is of great practicalV advantage and utility, as well as for compound tool-rests employed upon other engine-lathes.
The handle-piece can be used interchange-4 ably either upon the screw or upon either end d or d of the arbor D at the convenience of the operator, and renders the feed conveniently operative when the rest is central or when swung to the extreme right or left to such an extent as brings it closely adjacent to the head of the lathe or over the base of the tail-stock, as illustrated in Fig. 1.
I claim as of myinvention and desire to secure by Letters Patent- I.- In an en gine-lathe embodying a tail-stock having a rearwardly-odset standard, and a compound tool-rest provided with a pivotallyadjustable swing-plate and top shoe carrying the tool-rest; screw for said shoe,.of a lateral screW-operatf ing arbor carried upon said spring-plate, and having its end iitted for receiving the removable handle-piece that fits the feed-screw end, and spiral connecting-gears arranged on said For use with this otf.
the combination, with the feed` arbor and feed-screw, substantially as set forth. 4
v 2. The combination, of the tool-postesupporting slide having the narrowed rear end, and provided with the Vunder bearing b and lateral top bearings e e, the swinging guideplate, the feed-screw threaded'longitudinally i-n said guide-plate and arranged through the ,bearing b, the transverse arbor mounted in the bearings e on said slide-plate, and having oppositely-projecting ends adapted for receiving a removable handle-piece, the collars Yfm, and n arranged on said arbor at the ends of the bearings, and the pair of similar spiraltoothed gears respectively fixed on said arbor .and on the neck of said feed-screw, for the purposes set iorth.
3. In a compound tool-rest for engine-lathes, the combination of the top shoe provided at its outer end with lateral bearings and a housr ing-shell thereon, a transversely-disposed arbor mounted insaid bearings, the feed-screw journaled in a bearing at the under side of said top shoe, the pair of gears connecting said arbor and feed-screw, the ends of said arbor and feed-screw respectively projecting and similarly formed with splines, and the handpiece provided with a socket adapted for interchangeably ttin g said screw and arbor ends, for the purpose set forth.
Witness my hand this 10th day of May, i
` ALBERT F. PRENTICE.
