GEARING FOR METAL WORKING MACHINES.

Application filed February 13, 1923, Serial No. 618,786. Renewed March 1, 1927.

My invention relates to metal cutting machines of the boring mill type adapted to perform a number of operations which ordinarily require separate machines.

The objects are to provide new and 1mproved controlling means for such machines whereby quick and accurate manipulat on 1S possible when working metal of any size or shape; to provide power controll ng means and hand controlling means having fewer parts than heretofore deemed possible, thereby reducing theup-keep to a mln mum, and increasing the accuracy to a maximum.

Briefly, the invention includes transmission of power through the speed change gearing to actuate the feed change gearing; means for connecting the feed change gearing with mechanism for imparting endwise movement to the spindle, vertical movement to the saddle or horizontal movement to the taken on the line taken on the line taken on the line taken on the line taken on the line column; means for reversing the movements Speed ciumge gearr'ing.

Spur gear 8 meshes with a gear 10 fixed to a pinion 11 keyed to a shaft 12 mounted in bearings cast integrallyy with the saddle. The pinion 11 meshes with a gear 13 on a shaft 14 mounted in bearings cast integrally with the saddle. Shafts 12 and 14, hereinafter called series shafts, have series gears mounted thereon. Shaft 12 has rotatahly mounted series gears Hand 16, which are designed with clutch engaging parts 15 and 16 respectively, to engage clutch members 17 and 18 fixed to shaft 12, and shaftl i has afixed series gear 19 adapted to mesh with series gear 16. The series gears 15 and 16 are cast together and have'between them-an annular groove into which fits the end of an arm 15 actuated by a lever -16 outside of the saddle.

A shaft 20, journaled in bearings cast inte- I grally with the saddle, has fixed thereto

intermediate gears

21, 22, 23 and 24 adapted to mesh with their respective

speed change gears

25, 26, 27 and 28 slidably keyed to a shaft 29 j ournaled in bearings cast integrally with the saddle. The gears and 26 are cast together and have between them an annular groove 30,"inxwhich fits a yoked member 31 secured to a square shifting rod 32 sliding in bearings fixed to the saddle. Gears 27 and 28 are cast together and have between them an annular groove 33, into which fits a yoked member 34 fixed to a square shifting rod 35 sliding in bearings fixed to the saddle. Shiftingrods 32 and 35 have notches 36 and 37 on their adjacent faces adapted to receive-the end of a shifting lever 38 universally mounted on a bracket fixed to the saddle. Shaft 29 extends out of the saddle and has keyed thereto a driving pinion 39 which meshes with a bull gear 40 fixed to a. sleeve 41, journaled in

main hearings

42 and 43, and having a spindle or tool bar 44, slidably keyed therein, to which cutting tools may be secured in the usual manner.

The operation of the speed gearing is as follows: Three series of speeds with four speeds to each series are transmitted to the spindle 44 through the series shafts, series gears and speed change gears. The first series of speeds are transmitted to shaft through the series shaft 14, fixed series gear 19, rotatably mounted series gears 16 and 15 and gear 23. The four speeds are transmitted to the spindle 44 through either of the shifting gears 25. 26, 27 or 28 by shifting them, by means of the universally mounted lever 38, into mesh with their respective gear The second series of speeds is transmitted to shaft 20 through series shaft 12, clutch member 17, series gear 15 and gear 23.

The third series of speed is transmitted re shaft 20 through series shaft '12, clutch member 18, series gear 15 and gear 24.

The eight speeds of the second and third series are transmitted to spindle 44 by shifting either of the

gears

25, 26, 27 and 28 in IQIieSl'l with its

respective gear

21, 22, 23 or Change feed gearing and reversing mechamlsm therefor.

Shaft 29 has a gear 45 frictionally coupled thereto and hereinafter called a friction gear. Gear 45 meshes with a gear 46 interal with a ear 47 rotatably mounted on a xed shaft 4 The frictional coupling permits gear 45, in case of sudden or excessive strains, to rotate relatively to its shaft there- 3y avoiding danger of stripping the gears.

he gear 47 meshes with gear 49 cast integra ly with bevel gear 50 meshing with bevel gear 51 which in turn meshes with another bevel gear 52. Bevel gears 50 and 52 are rotatably mounted on a shaft 53, and bevel'gear 51 is rotatably mounted in a bearin fixed to the saddle.

55 actuated by a lever 56, to engage either 50 and 52 to impart forward or reverse movement. The parts beginning with the reference character 50 and ending with 58 constitute thereversing mechanism for the feed change gears. A'shaft 53, which is 1ournaled in bearings cast integrally with the saddle, has fixed thereto a gear 59, which meshes with a gear 60 of a group of

gears

60, 61, 62, 63, 64, 65, 66, 67 and 68, to impart a movement to a selective series of gears.

Gears

60, 62, 64' and 66 are respectively fixed to rotatably mounted pinions, 61, 63, and 67. Pinion 61 meshes with gear 62, pinion 63 with gear 64, pinion 65 with gear A clutch 54 slidab y keyed to shaft 53 is moved, by an arm- 66 and pinion 67 with gear 68. Pinions 61 and 65 are rotatably mounted on a shaft 69, gear 68 is fixed to shaft 69 to prevent endwise movement, and pinions 63 and 67 are rotatably mounted on a shaft 69 fixed to the saddle. A gear 70, slidably keyed on a shaft 71, has an annular groove 72 adapted to receive theend of an .arm 73 actuated by a lever 74, and may be moved into engagement with either of the feed series gears 60, 64 or 68. Shaft 71 is mounted in bearings cast integrally with the saddle and has an angular part 76 on which is mounted a gear 77 meshing with a tumbler gear 78 adapted to engage any of the change gears 79, 80, 81 and 82,-which are keyed to a shaft 83 mounted in hearings fixed to the saddle. The tumbler gear 7 8 is mounted on an arm 78 pivoted on the hubs of gear 77, concentrically with shaft 76, and having on its end a spring-pressed latch adapted to hold the gear in mesh. Gear 82 meshes with a gear 84, which is rotatably mounted on sleeve 41 and meshes with a wide face gear 86 fixed to a shaft 87 having slidably keyed thereon a shifting gear 88 which is shifted by an arm 89 secured to a. shaft 90 having fixed thereto a lever 91 outside of the saddle.

The operation of the feed change gears is as follows: the power is transmitted to shifting gear 88 from the speed change gearing, through friction gear 45; gears 46, 47 and 49; bevel gears 50, 51 and 52. When the feed change gears are rotating in one direction, clutch 54 engages clutch face 57 on bevel gear 50 and. when rotating in oppositedirection, clutch 54 engages clutch face 58 on bevel gear 52, and transmits thepower to shaft 53, gear 59,

gear

60, 64 or 68, slidably keyed gear 70, shaft 71, gear 77. tumbler gear 78, gear 79, 8O, 81 or 82, gear 84,

llin

wide face gear 86, shaft 87, to shifting gear The change feed gearing thus described is used to vary the endwise feed of the spindle; the vertical feed of the saddle, horizontal feed of the column or the movement of any other element deriving its power from the column feed shaft.

Spindle feed mechanism.

The spindle feed mechanism comprises agear 92 keyed to a shaft 93 having a feed screw part 94 fitting within a screw threaded nut 95 fixed in a bearing 96 rotatably secured to spindle 44.

Saddle adjusting mechanism.

gear 100 having a depending sleeve 101 in ternally threaded to receive a saddle adjusting screw 102 fixed in the top of the column.

The depending sleeve 101, which is j ournaled in a bearing 103, has ball bearingsv interposed between the bottom of its bearing 103 and a securing nut 104.

Column adjusting mechanism.

The column adjusting mechanism coniprises a gear 105 east with a spiral gear 106 rotatably mounted on the fixed shaft 99. Spiral gear 106 meshes with a spiral gear 107 sphned to a, column feed shaft 108 mounted in hearings in the column. The

'column shaft 108 extends vertically from the saddle and is adapted for use in transmitting movement to any suitable parts on a machine, such as the column, work-table, etc. The mechanism for effecting this transmission may be of any suitable type.

\Vhen it is desired to move the spindle cndwise, the saddle vertically or the column horizontally, shifting gear 88, may be actuated by lever 91, to mesh with

gear

92, 97 or 105. A very rapid movement is effected by shifting gear 84 until a frusto-conical clutch member 109 engages a clutch member 110 east with a gear 111 rotatably mounted on sleeve 41, and held in place by a ring 112. Gear 111, meshes with a bypass-gear 113 fixed to the series shaft 14. It will be seen that, by shifting clutch member 109 into engagement with clutch member, 110, by a lever 114 through the medium of a hollow shaft 115, passing over shaft 90, and

a yoke 116, gear 84 will be out of mesh with gear 82 but still in mesh with the wide face gear 86 and a very rapid movement of the I spindle, saddle or column is effected through a train of gears which by-passes the speed change and feed change gearing.

The hand-controlling mechanism comprises a hand-wheel .117 secured to shaft 118; mounted in bearings fixed to the saddle. Shaft 118 has at its end a fixed bevel gear 1l9'meshing with a bevel gear 120 fixed on shaft 87 which carries the shifting gear 88. If it is desired to control the feed of the' spindle,'saddle or column by hand, shifting gear 88 is moved in mesh with the

gear

92, 97 or 105, the same as when operated by power except that the change feed gearing is disconnectedwith the motor 3, andthus a hand controLis effected through very few parts.

Sleeve 41 which forms the immediate support for the spindle extends through the with change gear 79, 80, 81 or 82. Thus the series gears 60, 64 and 68 impart three different feeds to the change gears 79, 80, 81 and 82, making a total of twelve different feeds from the feed changing gearing.

\Vhen it is desired to reverse the feed change gears and consequently the spindle, saddle or column, assuming clutch 54,1;0 be in engagement with clutch face 57 of gear 50, lever 56 is moved to shift the slidably keyedclutch 54 into clutching engagement with the opposite clutch face 58 of gear 52 and a reverse movement will be imparted, as gear 52 rotates in the opposite direction to gear 50 due to the interpositioning of gear 51.

To disconnect the feed change gears, and consequently the spindle, saddle or column, from the speed change gears and motor, clutch 54 is shifted by lever 56 out of engagement with clutch faces 57 and 58. and held in a neutral position between them. Thus the feed change gears are disconnected from the speed change gears, as bevel gears 50 and 52. having the clutch faces thereon, are rotatably mounted on shaft 53.

When it is desired to change the speed of the cutting tool; that is, the speed of rotation, and endwise feed, of the spindle; or the speed of rotation of the spindle, and vertical feed of the saddle; or the speed of rotation of the spindle, and the horizontal feed of the column, it may be done by simply shifting the speed change gears with levers 16 and 38. By moving lever 38, downward and sidewise, the inner end will disengage.

notch 36 and engage notch 37, and move gears 27 and 28 through the medium of shifting rod 35.

By moving lever 38 upward and sidewise, the 1111-31 end will dis-.

lUU

consequently change gears 23, 26, 27 or 28 1 making a total of twelve speeds from the speed change gearing.

The feed of the spindle, saddle or column is changed proportionately, thus saving considerable time by avoiding manipulation of a number of levers for the proportionate change in feed.

When a very rapid movement is desired of the spindle endwise, the saddle vertically, or the column horizontally, lever 114 is moved upward to effect an engagement of frusto conical clutch member 109 with clutch member 110 and move gear 8 1, which is fixed to' the frusto-conical clutch member 109, out-of mesh with gear .82 but keep in mesh with wide face gear 86. Thus a very rapid movement of either the spindle, saddle or column may be effected through by-pass gear 113, gear 111,

clutch members

110 and 109, gear 84, and wide face gear 86.

To control by hand the endwise feed of the spindle; the vertical feed of the saddle; or horizontal feed of the column, the feed change gears are disconnected from the speed change gears by moving lever 56 so that clutch 54 will be in a neutral position. The shifting gear 88 is moved by lever 91 intomesh with either

gear

92, 97 or 105 respectively of the spindle, saddle and column mechanism,'hand wheel 117 is turned and a movement of either the spindle, saddle or column is then effected.

The direction of motion of the several chains of gearing may be reversed by reversing the motor, and the direction of motion of the feed change gearing may be independently reversed by moving lever 56 so that clutch 54 will engage the opposite face.

If it is desired to reverse the rotation of the spindle and continue the feed in the same direction, lever 56 is moved to engage clutch 54 with the opposite clutch face;
