LATHE-FEED.

SPECIFICATION forming part of Letters Patent No. 701,564, dated June 3, 1902. Application filed nmhiaieo'z. Serial lilo-98,065. (No model.)

T all whom it rnaty concern:

Be it known that we, BENGT M. W. HANSON, a citizen of Sweden, and FREDERICK W. Gon- DON, a citizen of the United States, both residing at Hartford, Hartford county, Connecticut, have invented certain new and usefulImprovements in Lathe-Feeds, of which the following is a specification. This invention pertainin g to improvements to in lathe-feeds will be readily understood from the following description, taken in connection With the accompanying drawings, in which- Figure 1 is an end elevation of a lathe provided with feed mechanism exemplifying our 1 5 present invention, the change gears being omitted and part of the quadrant being broken away; Fig. 2, a vertical transverse section of the main parts of the mechanism; Fig. 3, a front elevation of the main'p'arts of the'mechzo anism, certain details appearing in vertical section; and Fig. 4, a plan of the-tumbler.

In the drawings, 1 indicates the bed'of the lathe; 2, the head-stock; 3, the arbor {4,- the: lead-screw; 5, the change-gearstud; 6,'the arbor-feed pinion; 7, the driven. gear of the stud; 8, the reversing-gears in the head-stock, I

all the parts thus far referred to being constructed as usual except that while the pro? I jecting end of change-gear stud'5 is adapted to receive the ordinary change-gears such is not the case with the end of the lead-screw l;

0, a long pinion supported by the lathe-bed parallel with the lead-screw 10, the head end of this pinion, the same being adapted to receive the change-gear in line with a changegear on change-gear stud 5; 11, a change-gear thus mounted on the end of the long pinion;

12, an ordinary quadrantfiSocalled, for ad-- justably carrying such intermediate gear as may be employed betweenchange-gearsvon the change-gear stud and the end of the long pinion; 13, a longitudinal guideway parallel with long pinion 9. and extending its whole length and having the form of a rocking frame; 14:, arms at the end of this guideway extending inwardly toward the journals of the long pinion; 15, hearings on these arms, with their common axis coincident with the axis of long pinion 9, the guideway thus rocking and the carriage to traverse the guideway; 23,

transversely upon the axis of the long pinion; 16, a carriage arranged to slide lengthwise in guideway 13; 17, an idle gearjournaled in car riage 16 and constantly meshing with the long pinion regardless of the position of the carriage in the guideway; 18, a series of gears of diverse size fast on the lead-screw, a longitudinal adjustment of the carriage 16 in conjunction with the angular adjustment of the guideway permitting idle gear 17 to be put into gear with any selected one of gears 18; 19,- a finger-latch pivotedto the guideway; 20, a fixed segment of detent-hole's adapted to be selectively engaged by latch 19 and hold the guideway fixedly in adjustedangular position after idle gear 17 is properly engaged with one of gears 18; 21, a pinion journaled on carriage 16; 22, a longitudinal rack carried by guideway 13 and engagedby pinion 21, so that the turning of the pinion will cause it a crank fast with pinion 21; 24:, a detent-pin carriedlby this crank; 25 ,two longitudinal series of detent holes in the gu'idew'a'y, adapted. to be selectively engaged-by detent-pin 24, and 26 a casing secured against the front of the lathe-bed near its head end and serving toinc'l ose gears 18 and furnish bearings for the lead-screw and long pinion and to support the guideway.

The usualchange-gears give motion to the long pinion from change-gear stud 5, and the change-gears as interchangeable elements need not be employed i the'variety of gears in group 18 is sufficient to satisfy the speed ratios desired for the lead-screw. By releasing detect-pin 24: and turning crank 23 and putting the detent-pin to a properly-selected one of de'tent-hol'es' 2-5" the carriage can be traversed along in the. guideway and idle gear 17 brought to the plane of any selected one of" gears 18. By releasing latch 19 and then rocking the guideway and then engaging the latch with the properone' of its detent-holes 20 the idle pinionc'an be brought properly into gear. withthat oneof gears 18 with which it has been brought .into line.

While the device has been illustrated and described as a lathe-feed, it is nevertheless to be understood, as will be obvious, that the invention will well lend itself to numerous other situations.

\Ve claim as our invention 1. The combination, substantially as set forth, of a shaft provided with a series of gears of diverse sizes, a pinion disposed parallel with said shaft and having a length equal to that of said series of gears, aguideway disposed parallel to said pinion and arranged to rock upon the axis of the pinion, a carriage mounted to slide in the guideway, a gear mounted in the carriage and engaging said long pinion and adapted to engage any of said series of gears, and means for securing the rocking guideway and the carriage in position.

2. The combination, substantially as set forth, of a shaft provided with a series of gears of diverse sizes, a pinion disposed parallel with said shaft and having a length equal to that of said series of gears, a guideway disposed parallel to said pinion and arranged to rock upon the axis of the pinion, a carriage mounted to slide in the guideway, a gear mounted in the carriage and engaging said long pinion and adapted to engage any of said series of gears, gearing connecting the carriage and gnideway and serving to shift the carriage along the guideway, and means for securing the rocking guideway and the carriage in position.

3. The combination, substantially as set forth, of a shaft provided with a series of gears of diverse sizes, a pinion disposed parallel with said shaft and havinga length equal to that of said series of gears, a guideway disposed parallel to said pinion and arranged to rock upon the axis of the pinion, a carriage mounted to slide in the guideway, a gear mounted in the carriage and engaging said long pinion and adapted to engage any of said series of gears, a rack supported by the guideway, a pinion journaled on the carriage and engaging the rack, a crank for turning the pinion, and means for locking the rocking guideway and the carriage in adjusted position.

4. The combination, substantially as set gears of diverse sizes, a pinion disposed parallel with said shaft and havinga length equal to that of said series of gears, a guideway disposed parallel to said pinion and arranged to rock upon the axis of the pinion, a carriage mounted to slide in the guideway, a gear mounted in the carriage and engaging said long pinion and adapted to engage any of said series of gears, a rack supported by the guideway, a pinion journaled on the carriage and engaging said rack, a crank for turning said pinion, a detentpin carried by said crank and adapted to engage selective detentholes in the guideway, and means for locking the rocking guidewayin adjusted position.

5. The combination, substantially as set forth, of a shaft provided with a series of gears of diverse sizes, a second shaft mounted parallel therewith, a pinion upon said second shaft, a guideway disposed parallel with and arranged to rock upon the axis of said second shaft, a carriage mounted to slide in said guideway, an idle gear mounted in said carriage and geared to said second shaft and adapted to engage any of the gears of said series of gears, and means for locking said rocking guideway and the carriage in adjusted position.

6. The combination, substantially as set forth, of a casing, a shaft journaled therein and provided with a series of gears of diverse sizes inclosed by said casing, a'pinion mounted in said casing parallel with said shaft and having a length equal to said series of gears, a guideway disposed parallel with said pinion and mounted to rock upon the axis thereof, a carriage arranged to slide in said guideway, an idle gear mounted in said carriage and engaging said pinion and adapted to engage anyone of said series of gears, and means for locking the rocking guideway and the carriage in adjusted position.
