VERTICAL LATHE.
Application filed May 18, 1926.
T 0 all whom'z't may concern Be it known that I, lVALLAon E. lVAno, a citizen of the United States, and resident of Rochester, county of Monroe, State of New York, have invented an Improvement in Vertical Lathes, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.
This invention relates to metal working lathes and more particularly to an improved type of lathe wherein the ways on which the tool saddles are mounted extend vertically, with the operating connections and gearing for effecting changes of feed and changes of speeds housed in the base of the machine. One principal object of the invention is to provide improved means for mounting, and controlling the movements of the tool saddle and tool holder with relation to an operating screw therefor, whereby either a vertical feed or a horizontal cross feed or a taper, or pattern-controlled feed may be obtained at will, with a capability of changing the setting of a machine for any required purpose in'a quick and convenient manner. To these ends one important structural feature of invention consists in arranging the feed screw so that it may be held from endwise movement in a fixed swivel to feed the tool-saddle, or it may be arranged so that the Screw moves endwise in a relatively fixed nut according to the requirements of the work in hand. The foregoing and other objects'and advantages of the invention will more fully appear from the following detailed description, and the distinctive features of novelty will be thereafter pointed out in the appended claims.
Referring to the drawings:
Fig. 1 is a front view of a vertical lathe embodying the invention;
Fig. 1 is a fragmentary elevation and section of a feed screw;
Fig. 2 is a side view thereof partly in ver tical section and looking from the right in Fig. 1;
Fig. 3 is a plan view of the machine with portions broken away in section;
Fig. 4 is a partial. vertical section on line a e of Fig. 1;
Serial No. 382,332.
Fig. 5 is a partial horizontal section on line 5-5 of Fig. 1;
Fig. 6 is a fragmentary elevation showing a device for holding a controlling clutch in adjusted position; and
Fig. 7 is a detail transverse section on line 77 of Fig. 6.
The base 1 of the machine constitutes a housing for the change speed and change feedconnections to be described and has fitted at the rear thereof an upright structure 2 at the front of which are formed spaced apart slide-ways 3, 4 for the tool saddles. Horizontally journaled in the base of the machine is a shaft 5 which may be considered the prime drive shaft of the machine, having as shown a projecting end to which is fixed a bevelled gear 6 meshing with a bevelled pinion 7 on a shaft 8 which may be a power distributing shaft from the motor unit and adapted to drive one or more machines that may be geared thereto. The shaft 5 has slidably keyed thereon a pinion block 9 bearing pinion faces 9, 9 9 of diverse sizes with the intermediate one thereof the largest. This pinion blockis engaged by a suitable shifter 10 for actuation to its adjusted positions. A shaft 11 is journaled in the base in parallelism with the shaft 5 and adjacent thereto and has keyed thereon spaced apart gears 12, 13, 14 adapted to mesh with the pinion faces 9 9", 9 respectimely as the pinion block is shifted to its several positions of adjustment. The shaft 11 has fixed to the inner end thereof a bevelled pinion 15 which drives a bevelled gear 16 keyed to the spindle 17. The work spindle 17 is vertically journaled in the base with its upper extremity 17 projecting thereabove and adapted to receive a face plate or work holding chuck. Thus by the shifting of the pinion block 9 three changes of speed to the spindle may be obtained.
-The' shaft 11 has detachably keyed to its outer projecting end a pinion 18 engaging a gear 19 detachably keyed to thevend of the shaft 20 journaled in the base. The pinion 18 and gear 19 are removable and replaceable by others of different relative sizes whereby a change of speed ratio from the shaft 11 to to shaft 20 may be obtained as desired. This connection to the shaft 20 is for the transmission of feed movement to the tools and the shaft 20has keyed thereon a pinion 21 which mesheswith gears 22, 23 loosely mounted on shafts 2 1, 25 respectively journaled in the base at each side of the shaft 20. Each of the shafts 2d, 25 has slidably keyed thereon a double ended clutch hub 26 which when moved in one direction engages a cooperative clutch face on the hub of the gears 24, 25 to engage them with the shafts on which they are mounted. Each of the shafts 24:, 25 has fixed at its inner end a 'naled in the base and equipped with a bevelled pinion 27 engaging a pinion 28 having a hub 28 swiveled in the base and having a passage therethrough in which is slidably keyed a plain shaft portion 29 depending from a screw 29 which extends squared projecting end 31 adaptedv for engagement with a wrench or like hand oper-- atingdevice. The'shafts 24, 25 also have loosely journaled thereon adjacent the outer ends thereof gears 32 which are engaged with the gear 12 on the shaft 11 and constantly driven thereby. These gears have hubs 32 thereof formed with clutch faces engageable by the other ends of the clutch hubs 26. Thus by shifting these clutch hubs to make fast the gears 32 to their shafts, power may be transmitted directly from the.
Each of the respective vertical slideways 3,4 has slidingly fitted thereon a saddle 4:0
equipped with a nut 41 engaging the'screw tion of angular adiustment.
29. This saddle while adapted for free sliding movement along its slide-way is equipped with provision for rigid and stationary clamping to such slide-way to permit the functioning of the mechanism in one of the ways of which it is capable as later explained, and for this purpose the saddle is equipped with clamping screws 42 engaging a clamping shim 13 and having operating handles 44: for setting up such screws. The face ofthe saddle 10 is formed witha usual undercut ring slot 15 in which are engaged the T-headed clamping bolts 15 which s cure a swivel head 6 .6 thereto in any posi- The swivel head 16 has slidingly fitted thereto a tool holder 4.7 which as usual engages undercut ways of the swivel head. The tool holder is adjustable with reference to the saddleand its swivel plate by means of a screw 18 engaging a nut 49 of the tool holder. this screw being swiveled in a. sleeve head 50. The sleeve head 50 is borne by a slide block 51 which has dove-tailed sliding engagement with a rail 52 equipped for this purpose with undercut ways. The rail 52 is pivoted by a pin 53 to a plate 54 which is borne by, and depends from, a bracket head 55. The
plate 5 1 is formed with upper and lowerarcuate slots 56, 5'? in which clampbolts 56 are engagedv to clamp the end portions of therail 52 immovably to said plate in any position of angular adjustment to which such rail may be set. The bracket head .55 is slidinglyfitted to a vertical way 3l of thelathe and it is adapted to be clamped immovablv thereto when desired by clamp bolts 59. The brackethead 55 has swiveled therein the upper end of the feed screw wh ch is thus held from 'endwise movement with respect thereto as indicated at 60. Suitable means may be provided. for counterbalancing head 55 and the saddle, this being shown as a usual cable or chain 61 passing over a plate 62 at the top of the upright and holding a counter weight 63. With the described construction it may now be understood that when the lathe'is-tobe used for vertical turning. the head 55 will beclamped rigid to the upright by the clamp screws 59 and the rail 52 set vertical, i. e, in paral- 'lelism with the saddle ways, whereupon on slots 56. 57 which will cause the tool holder to move horizontally on the swivel plate l6 as the saddle bearing the tool holder moves vertically. For turning horizontal work the saddle 10 is clamped immovably to its ways by the clamp screws 42 and the head 55 is released to slide freely on the vertical ways.
Then on setting the rail 52 at a suitable angle, the head 55 will he moved vertically with the screw 29 which operates through the then stationary nut 41 and this movement will cause a transverse movement of the tool holder on the saddle so that the tool may thus befed horizontally over the work surface. It will be understood that swivel head 46 may be set as usual at the proper angle so that the tool will be presented squarely to the work in whichever direction it may be fed, the swivel connection of the sleeve 50 with the block 51 indicated at 50 permitting this adjustment without disturbing the relation of the tool holder to the rail 52.
The notches 39, already referred to, are engaged by oppositely facing dogs 64, 65 pivotally mounted on the same pivot pin 66, borne by the housing and adapted to engage oppositely facing shoulders 39 39 respectively of the notches and they are spring pressed to Snap into these-notches when permitted, by a coil spring 67 mounted on the pi 66 and having its ends engaging the respective dogs. These dogs have tail pieces 6 65 respectively which are engaged by down-turned ends of a tilting plate 670 also pivotally mounted on the pin 66. The plate 670 is pivotally engaged as indicated at 68 near the right hand end thereof as shown in Figs. 2 and 6 by the vertically extending rod 69 which is slidably guided upward alongside the vertical way, it being understood that there is one of these rods with the described cooperative mechanism associated with each of the slide rods 34 for each of The rod 69 is equipped with spaced apart collars the saddle and tool head mechanisms.
70 adjustably fixed thereon and adapted to be impinged by the saddle or by the head 55 according to which of these is movable, to move the rod 69 and hence cause the plate 67 to press one or the other of the dogs 64:, 65 out of its notch according to whether the connection has been set for the rapid traverse or for the feed. Thus if the hub 26 has been set for rapid traverse, upon the end of the rapid traverse movement, the rod 69 will be lifted and the dog 64 raised to permit the clutch hub to move back to neutral position, while if the feed connection has been engaged by the shifting of the clutch hub to the left in Figs. 2 and 4, upon the completion of the feed movement the rod 69 will be moved downward disengaging the dog 65 from its notch and again permitting the clutch hub to move to neutral position. It will be understood that while I herein show the tool saddles and associated mechanism as the same on the two vertical ways. this is merely illustrative in certain broader aspects or" the invention and tool mountings of different character one from another may be employed on the respective upright ways if slideaway, a feed screw equipped with driving means and having a mounting permitting endwise'movement thereof with respect to such driving means, asaddle mounted for movement on said slide-way bearing a slidahle tool holder and equipped with a nut engaging said screw, and a head also fitted to said slide-way in swiveled engagement with said screw and bearing means for effecting a sliding movement of said tool holder, said saddle and said head equipped with means for selectively clamping them stationary with respect to said slide-way.
