TURRET-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 576,717, dated February 9, 1897'.

Application filed February 8, 1896. Serial N0. 578,461. (No modehl Be it known that l, JOHN L. BOGERT, residing in Flushing, Queens county, New York, have invented certain new and useful Improvements in Turret-Machines, of which the following is a specification. a

My invention relates to improvements in the general construction and arrangement of the turrets in turret-lathes and analogous machines.

The object of my invention is to permit the work to be passed partly or entirely into or through the turret as and when desired to enable the tool carried by the turret to pass close up to the face-plate.

The invention consists in a turret having alined apertures leading across it for the passage of the work and novel means for holding the turret rotatively upon a cross-slide of a lathe. The turret and cross-slide are also so arranged that the chips and oil can be carried away without interfering with the crossfeed screw of the cross-slide.

The invention also consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure l is a partly sectional plan view of a turret provided with my improvements, shown in position on a cross-slide, the section being taken on the line l l in Fig. 2. Fig. 2 is a vertical cross-section on the line 2 2 in Fig. 1. Fig. 3 is a plan view of the cross-slid e, the turret being removed; and Fig. 4 is a side elevation of the turret detached from the cross-slide.

In the accompanying drawings, in which similar numerals of reference indicate correspon ding parts in the several views, the'number l indicates a cross-slide, which may be of suitable construction and arranged to be carried and moved on a carriage (not shown) of a lathe or analogous machine in any suitable manner. y

The cross-slide 1 is shown in the drawings in the form of a hollow casting having an annular ring or seat 2 near its upper outer edge upon which the turret 3 rests and rotates, and the cross-slide l also has a central cavity or recess l and a bore or bearing lb and an annular seat or shelf l. The cross-slide l also has an annular cavity or chamber l, formed by the bottom plate le, outer walls lf,

and inner walls 1g, and across the top of this cavity ld extend connecting-arms 1h, between which arms openin gs li are formed, as shown.

The turret 3 is generally at its upper portion of ordinary or suitable form provided with a lower annular rim 3, which rides on the ring or seat 2 of the cross-slide. In each side or face of the turret an aperture or recess 4 is formed, all of which lead to a central opening 5. The apertures 4 in opposite faces of the turret are in line, so that a bar or other work to be operated upon can pass entirely through the turret through the alined openings 4.

From the central lower portion of the turret 3 depends a cone-like hub or pivot 6, which passes into or in line with the central cavity l of the cross-slide. The hub 6 ts in a corresponding bore 7 in a bushing 7, which is located in the bore l of the cross-slide and has an annular shoulder or flange 7b, that rests on the seat lc of the cross-slide, the bushing 7 being secured thereto by screws 8, as shown in Fig. 2. The flange' 7b has its convex surface 7 so constructed as to engage with a clamp or binder-ring 9, and also has a top flat seat or surface 7 d, upon which latter surface the turret 3 rests, as shown in Fig. 2. As shown, the convex surface 7 C of the flange 7b of the bushing or bearing 7 is conical.

The clamp or binder-ring 9 serves as a gib, which lits in a corresponding recess 9? in the under surface of the turret and in a corresponding annular recess la in cross-slide l, and said ring 9 has a surface 9b corresponding to the surface 7c of the bushing or bearing 7. The ring 9 is held in place on the turret and may be adjusted vertically by means of bolts or screws l0, that pass downwardly through said turret and screw into suitable threaded apertures in the ring. Ihave shown three screws l0 placed at about one hundred and twenty degrees apart and located between corresponding apertures 4 in the turret. By

adjusting the ring 9 up or down the corre-- sponding surfaces 7c and 9b of the bushing 7 and ring 9 may be drawn more or less tightly together for the purpose of adjusting and holding the turret in position on the cross- IOO slide and also i'or taking up wear between the parts. l-linder-nuts'lO are provided on the adjusting screws or bolts l0, whereby the turret can be bound tightly to the cross-slide in any desired position through the medium of the ring 0 and bushing 7. By preference washers 10" are interposed between the nuts l0 and the top of the turret. rlhis bushing and ring also act to resist lateral thrusts of the turret and also serve to keep the turret from tilting on the erossslide. The cone-like hub (i and the corresponding bore 7 in bushing 7 also assist in resisting lateral thrusts of the turret and in keeping the latter centered on the cross-slide, the hub (3 and bushing T serving as a pivot and bearing for the turret.

1l are suitabl y-arran ged set-screws carried by the tops of the turret over the apertures itor the purpose of holding a tool-bushing or other suitable device in an aperture for machining' or guiding work therein. The tools may also be held on the fiat side faces 3C of the turret in line with the apertures et by means of screws that may enter tapped holes l2 in the faces 8C. (See Fig. l.)

Any suitable means may be provided for holding the turret in proper working position on the cross-slide. I have shown a verticallymovable pin li, carried in suitable bearings on the cross-slide l and adapted to enter apthe turret. The locking-pin 1i may be arranged and operated as shown in my Patent No. 551,846, dated December 2i, 1895.

To adjust my improved turret in position on the cross-slide l, the ring 9 is iirst placed in position in the cross-slide, and the bushing 7 is then placed in position in bore 1b and screwed firmly upon its seat le. The turret 3 is then placed upon the cross-slide so that its hub or pivot G iinds its seat in the bushing orbearing 7, the ring i) entering the groove 5), the part 3 of the turret resting upon the seat 2 on cross-slide l. The screws l0 are then passed lthrough their appropriate apertures in the turret and screwed int-o the ring 9, so as to draw the face 9b of the latter properly against the face 7 C of the bushing or bearin g 7. The turret can now properly rotate on the cross-slide, any suitable well-known means being employed for that purpose.

It will be observed that there is no pivot or standard passing from the cross slide upwardly through the turret, as in the old style of turret-macliines known to me and as shown in my Patent No. 551,8i6, before mentioned. For this reason I am enabled to provide the apertures 4 in the turret for the entrance and passage ot the work without interference by any of the working parts of the turret. Another advantage of this arrangement is that t-he work can be guided in the aperture or apertures in the turret either by allowing it to bear on the walls of the aperture or by inserting a suitable temporary bushing in the proper aperture 4. This will be found specially advantageous when the work is long and it is desired to move the turretnear or close to the face-plate or chuck (not shown) to enable the tool to operate close thereto.

In order to carry away chips and oil that may pass into the turret with the work, so as to prevent said chips or filings from injuring or interfering with the cross-feed screw ot the the cross-slide, not sliown,) I provide the hub or extension 6 with a vertical aperture or bore 17, which leads from the cavity 5 in the turret entirely through said hub and opens into the chamber or cavity l in the cross-slide. The chamber ln communicates with the chamber l in the cross-slide through an aperture or apertures l in the wall 1g, from which chamber ld the refuse passes away through an aperture l in the bottom l@ of the cross-slide or directly through the aperture l.

Itis evident that my improvements forholding the turret pivotally ou the cross-slide can be used whether the turret is provided with aperture -ior not.

My improvements are simple in construction, effective in use, and not liable to get out oi' order, and I do not limit my invention to the precise details of construction shown and described, as they may be varied without departing from the spirit of my invention.

Ilaving now described my in volition, what I claim ispropriate recesses 15 on the under surface of l.. A turret having apertures on opposite sides, and a hub or pivot depending therei from, combined with a cross-slide having a bushing or bearing to receive said hub or pivot, an adjusting ring or gib to bear on said bushing or bearing, and means for connecting said ring or gib with said turret7 as and for the purposes specified.
