Appi-ieation iiiea May aaien. seriai No. 715,276.

My invention relates particularly to planers for large and 'heavy Work, jsuc'h as are known as frog andsWitCh planers, in which the tools are fed to theY Work by hand.

The object of the'invention is to pro-y vde novel and improved mechanism, ,Whereby motion may be imparted at will to either or both of the tool holders byhand or by power, in accordance with the wish of the operator.y g Y y The invention" consists kof that certain novel construction and arrangement ofparts to beherei'nafter more particularly pointed outand claimed, in which the aboveresuits are attained. i

Figure@ is a perspective view of the rapid l traverse control mechanism separated from the other parts, and without the supporting bearings. l f n Referring to the drawings, 1 and 2 are tools clamped to tool holding `members of the usual formwhich are fastened to slides 3 and 4 which are slidably Vgibbed to lvertical guides formed on tlieiront suriaces et saddles 5 and. Saddles 5 and 6 are yslidably gibbed to rail `7. To the back ot saddle 5 is iiXed a nut, not shown, into which threaded rail screw 8, which is a long;

'Io feed rod 11 is slidably k iedfa similar planer provided with` this inechf bevel gear driving a similar train of mecha- -nisni giving vertical motion to. slide 4. It ywill be seen that by rotating rail screw 8 horizontal motion` will be given totool l,` the direction of horizontal motion depending on the direction of rotation of the rail' screw. iiiotionwillbe imparted to tool 1, the direction of vertical motion dependiii'gron the direction ofrotation yof* thefeed'rod. Simi;y

larly rotating rail screw 9 and feed rod 'l1 kwill impart motion to tool 2. Thek various vparts so far mentioned may be of the design By rotating .feed rod 10, vertical l commonly used for such parts for ,plaiie`rs, f

or of any otherk suitable design, Aanddo ynot require ifurther illustration or description.

The mechanism so far described differs from that usually Vemployed in the following' particular only. Hitherto only one feed rod has been employed and the vertical move-V nient for both tools has been imparted by. this feed rod. Thishasfiiecessitatedl the use oif mechanism in each head for engaging and disengaging the vertical :Eeediso thaty the tools could be moved vertically "either iiidependently or simultaneously. rllie usey ot separate feed rods in the manner described, avoids thisr complicationJ eachver'ticalfeed mechanism being permanently. geared. to its feed rod. y Referring now 'to Figure el.. the flic-ed rod shown `is representative koiZ both 'feed rrods and both rail screwsieach of which has, at

theend nearest the operator, hereinafter termed the right hand end, those parts hereiiiafter described which are concentric with it.

On the right hand end of each rail screw or feed rod is i clutch' 12. To' the left of clutch 12 and iu crewed and pinned driven a counterbored hole in vrail 7, isball thrust bearing 13.y Concentiic iviththe rail screw or feed rod, and to the right/of clutch 12,y are bronze sleeve 13a, spring lil, and washer 15. To the right of washer 15, and pinned to` the rail screw yor feed rod, is bronze sleeve 'Y the rail screw vor feed rod ris driving clutch 21 having clutch teeth 21 adapted to engage clutch teeth 12a on driven clutch 12;y This 1.6. The end of the rail screw orL feed rod iio driving clutch is ordinarily held out of engagement by spring 14 acting against washer 15, which in turn presses against an internal shoulder 21b formed in driving clutch The distance between shoulder 2lb and the end 21c of clutch 21 is slightly less than the length of sleeve 16, so that clutch 21 can turn freely, being machined to a running tit on bronze sleeves 13 and 16. wWhen clutch 21 is moved to the left in order to engage clutch 12, it pushes washer 15 over, compressing spring 14. ils soon as the pressure is relased, spring 14 acts to return clutch 21 to the position shown.

Cn the outer rim of driving clutch 21 are former ger r teeth 21d by means of which thcv clutch is revolved. Cn the outer surface of the clutch are mounted spring 22 and ball thrust bearing 23. The spring is maintained in a partially compressed position by sleeve 24, which is fastened to clutch 21 by screw 25. Acting against ball bearing 23 is a forked clutch shifter 26. When this shifter is moved so as to push ball bearing 2S to the left, clutch 21 is caused to move to the posi tion of tooth engagement. In case the tops of the clutch teeth come together so that clutch can not engage, spring 22 will be compressed. Spring 22 being much stiffer than spring 14, as soon as the driving clutch has rot-ated suficiently to bring its teeth opposite the spaces of the driven clutch, spring 22 will force clutch 21 into engagement, against the action of spring 14.

Clutch shifter 26 is pinned to shaft 2T having bearings in plate 18, which forms the end of the case on the rail, and plate 28, which forms the front of the case on the rail. To shaft- 27 is pinned lever or handle 29, to which is securely fixed detent 30 and knob 31. Then handle 29 is pulled down, this detent is engaged by latch 32, and clutch shifter 26 is moved to the left, causing clutch 21 to engage clutch 12. Latch 32 is held in place by flat spring 33, and is pivoted at its upper end on pin 32 fixed in plate 2S. rlie latch is formed with aA button 32 on its lower end so that it may readily be pressed back by the thumb of the operator. Then this button is pressed back the detent is released, spring 14 pushes clutch 21 to the right, carrying with it spring 22 and ball thrust bearing 23, forcing over shifter 26, revolving shaft 27, and raising` handle 29 and detent 30 tothe position :shown in Figure 35.

Each of the -two rail screws and each of thel two feed rods is provided with the associated clutches, sleeves, springs, bearings, clutch shifters, clutch shifter shafts, handles, detents, and latches described above, so that at will, each rail screw or feed rod may be coupled to its corresponding driving clutch. There are therefore, four of each of the above mentioned parts.

The gear teeth of the four driving clutches 21 mesh together so that the clutches are compelled to revolve together. Meshing with the teeth 21d on one of the driving' clutches are teeth 34C formed on the outer surface of shiftable clutch 34, which is loose on, and concentric with shaft 35, the inneil end of which is journaled in the end of the rail, while the outer end is supported by radial thrust bearing 36, housed in bushing 23'?, which is fastened to plate. 18 by screw S18. Cn the end of shaft 35 is keyed gear 39, which meshes with gear 40, keyed to shaft 41, which is manually rotatable by crank To reducefriction, shaft 41 is mounted on ball bearings 43, which are housed in gear cover 44, which is bolted to plate 18. Cn shaft 35 is mounted mechanically rotatable clutch 45 having teeth on its outer rim, by which it is driven by gear 46, which in turn is driven by a` motor through a. suitable train of mechanism to be described later.

Clutch 45 is provided with clutch teeth 45, adapted to engage clutch teeth, 34 formed on shiftable clutch 34. On shaft 35, and concentric therewith, is mounted bronze sleeve 4T, having shoulder 47, against which washer 48 is pressed by spring 49, which is held in place by bronze sleeve 50, fastened to sleeve 47 by screw 51. Shoulder 47, sleeve 50, and washer 4S thus maintain spring` 49 in partial compression. Washer 4S presses against an internal shoulder 34" formed in shiftable clutch 34, which may be caused to shift axially on bronze sleeves 4'? and 50. To the right of shiftable clutch 34 is manually rotatable clutch 52, which is pinned to shaft 35. Normally clutch teeth formed on the right hand end of clutch 34, engage clutch teeth formed on clutch 52, the clutches being held in engagement by spring 49. Consequently when crank 42 is manually rotated, shaft 41, gear 40, gear 39, shaft 35, clutch 52, and shiftable clutch 34, and the four meshing driving clutches 21, are all caused to rotate.

Should each of the driving clutches be in the position shown in Figure 4, they will revolve freely upon sleeves 13L and 1G and neither of the rail screws or feed rods will turn. Should, however, the operator pull down one of the handles 29, as for instance the one associated with rail screw 8, the corresponding clutch 21 will be caused to engage its clutch 12, and rail screw 8 will thereby be caused to rotate, moving tool 1 in a horizontal direction. Similarly by pulling down the handle 29 associated with rail screw 9, this screw will be rotatably coupled to the revolving mechanism, and tool 2 will thereby be caused to move in a horizontal direction. By pressing the buttons 32EL formed on the lower ends of the latches 82, the latches will be disengaged from the detents 30 on handles 29, which will permit the clutchs to reing the controller drum to its neutral position and disconnecting the motor from its source of energy. A movement of handle 82 to the opposite side of its neutral position will again couple clutch 34; with clutch gear 45 and move lever 7la to the opposite side of its neutral position so that controller 'T1 will so energize the motor as to cause it to rotate in the opposite direction. It will thus be seen that when handle 82 is in its neutral or mid position, motor G2 will stand still and the screws or rods vill be operatively connected to handle for manual operation. A movement of lever S2 will disengage the mechanism from hand lever 4i, and opearte it by means of the motor (i2, the direction of motion being controlled by the direction of motion of handle It will be seen that the invention provides an extremely convenient means for moving the two tools into any desired position. that they may be moved independently or simultaneously, and that the movement may be effected by hand or by power. Also no attention is required from the operator except to determine which tool he wishes to move, which direction he wishes to move it. and whether he wishes to move it by hand or by power. The mechanism itself is so arranged that all of the necessary actions are accomplished by a single movement, and the operators attention is not required for such matters as shifting clutches, throwing switches, disengaging feeds, or other similar actions.

It will be apparent that the mechanism may be changed in detail without affecting the general principles upon which its action depends. I, therefore, do not wish to confine the invention to the exact form shown. but to include all those forms falling within the scope of the appended claims.
