POWER RAIfiD-TRAVERSE AND FEED MOTION FOR mum.

Power Rapid-Traverse and Feed Motions for Planers, of which the following description, inconnection 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 planers,

and particularly to those of larger sizes adapted for use on relatively heavy and massive work. A principal object of the invention is to provide connections whereby the tool saddles and tool holders may be operated with a rapid traverse movement to bring them to operative position, and controlled by a relatively slower and separately actuated feed movement in the operation of the planer, and such connections equipped with controlling devices located at the saddle whereby the traverse and feed movements of the tools may be controlled by an operator from the locality of the saddle, and there being preferably provision whereby such control may also be effected from the side of the machine if desired. The foregoing and other objects and advantages of the in vention will more fully appear from the following detailed description, and the dis-. tinctive features of novelty will be thereafter pointed out in the appended claims.

7 Referring to the drawings:

dles 7, 8, and as'shown these uprights are also equipped with side tool heads 9. Itis ,dsirableand important that provision be made whereby the operator may control the rapid traversing and also the operative movements of the tools from'a point adjacent thereto so that hemay have thework under close observation in the manipulation of the tools and the present invention provides means whereby tliiscontrol may be effected in a convenient manner from either saddle. Power for the rapid traverse movements of the saddles and tool holders is derived from 'a motor 10 mounted on the top rail 5 which through reducing gearing 11' drives constantly a short shaft 12 journaled on the top rail intermediate its length. The shaft 12 has loosely fitted thereon spaced apart pinions 13, 1 1 which are selectively. engageable with saidshaft by a double ended friction clutch slidably fitted on the shaft. The gear 13 engages and drives a gear 16 fixed on a shaft'17 horizontally journaled on the top rail and extending-the entire distance between the uprights. The shaft 17 also has a gear 18 fixed thereon which maybe driven from the gear 1 1 in a reverse direction relative to the-drive of the gear 16 by means of an intermediate gear 19. The shaft 17 through bevel gears 20 drives a shaft 21 vertically journaled at the end of the upright 4 and extending downward to the base thereof. The'shaft 21 has slidably keyed thereona bevel pinion22 which operatively engages a bevel gear 23 fixed at the inner end of a short shaft 2 1j0urnaled in a'bracket 25 of the cross rail, the pinion 22 being also held to travel with the cross rail and to remain in mesh with the gear 23. The shaft 24 has fixed at its outer end a "pinion 26 which engages a relatively large gear 27 loosely journaled on a short shaft 28 fixed in the end of the cross .rail, The gear 27 engages a series of pinions 29, 30, 31 loosely mounted on end portions of the feed screws 32, 33 and the feed shaft 34 respectively, the feed screws being adapted for operating the respective saddles along the cross rail and the feedshaft 34 for imparting vertical movement to the tool holders on the saddles pinions 29, 30, 31 are equipped at their outer sides with clutch faces 35 which are engageable by cooperative faces 36 at one end of clutch hubs 37 slidably keyed on the respec- 1 05 in accordancewith the usual practice. The

tive shafts 32, 33, 34. These clutch hubs are operated by shifters 38 borne by shafts 39 extending to the outside of the housing and equipped with handles 40. For controlling this rapid traverse movement so as to engage it in either direction or to disengage it, the double yfriction clutch hub 15. is equipped with an arm 41 having connected thereto a rod 42 which extends to the side of the machine where it is engaged with a crank 43 fixed at the upper end of a rock shaft 44 vertically journaled to bracket bearings of the upright. This rock shaft 44 has fixed to a lower end portion thereof a handle 45 whereby it may be actuated from a position adjacent the upright. F or operating this rock shaft and thus controlling the rapid traverse from either of the saddles, this shaft 44 has slidably keyed thereto a bevel pinion 46 which is journaled in, and held from endwise movement by a sleeve 47 in the end of the cross rail. This pinion engages a bevel pinion 48 fixed on a short shaft 49 horizontally journaled at the end of the cross rail. The shaft 49 has fixed to its other end an arm 50 the outer end of which engages with a link 51. The other end of the link 51 is pivoted to the outer end of an arm 52 fixed toa rock shaft 53 which is horizontally journaled in the cross rail and extends the length thereof. The shaft 53 has slidably keyed thereon bevel pinions 54, there being one thereof journaled at side of each saddle and held to travel therewith. Each of these pinions 54 is engaged by a bevel pinion 55 ournaled in the saddle and having rigid therewith a handle 56 extending at the front of one side ofthe saddle. Thus by operating either of these handles 56 at either of the saddles on the cross rail, the rapid traverse for either direction of movement may be thrown into engagement or disconnected at will. For imparting feed movement to the feed screws andshafts 32, 33, 34, power is taken from a shaft 57 vertically journaled alongside the upright 4 and oscillated from a feedbox (not shown) at the base of the machine in-usual manner on each stroke of the table. The shaft 57 has slidably keyed thereon and carried by the cross rail a bevel pinion 58 which meshes with a pinion 59 xed at the inner end of a short shaft 60 journaledin bearings at thevouter end of the'cross rail. The shaft 60 has'fixed at its outer extremity a feed block 61 having a link connection 62 to a crank pin 63 borne by a driving bar member 64 of a clutch device adapted to engage a relatively large gear 65 loosely journaled on the shaft 28. To effect this clutch connection the clutch bar member 64 is loosely journaled on a hub 65 of the coiiperative to frictionally engage an internal clutch surface 65 of the gear 65. .The rock shaft 66 has fixed at its inner'end an arm 69 constituting a clutch finger andhaving at its inner end a pin 69 engaged by a cone 70 slidable on a reduced extension of the gear hub 65 The cone 7 O is engaged by a shipper yoke 71 pivoted at 72 to a bracket 73 borne by the cross rail. This shipper yoke has a downward extension past its pivot which bears a pin 74 engaging in a cam slot 75 formed in a cam head 76 which is fixed to a short rockshaft 77 horizontally j ournaled at the end portion of the cross rail. The shaft? 7 has fixed thereto an arm' 78,

the outer end of which is engaged with a link bar 79, the other end of which engages an arm 80 fixed to a shaft 81 horizontally journaled in the cross rail and extendingthe j The shaft 81 hasslidably for movement therewith. Each pinion 82 meshes with a coiiperative pinion 83 journaled in a bracket of the saddle and having a handle 84 rigid therewith, these handles 84 preferably and as shown, being located on the same side of the saddle as the handles 56 and in the present embodiment being directly thereover. Thus by manipulating a handle 84 at either saddle the gear 65 may be thrown into engagement with the oscillating feed movementfor transmitting the same to the feed screws and shafts. transmission from the gear 65 to the feed screws and shaft when the feed is to be employed, is effected through pinions 85 loosely mounted on the ends of the respective shafts 32, 33, 34. These pinions may be formed in- I ,teriorly as click boxes (not shown) in. ac-

This 3 a clutch face 36 on the end of the clutch i hub 37 coeperates when said clutch hub is thrown to the right as seen in Fig. 4. Thus by adjusting the clutch hub 37 on either of the feed shafts 32, 33, 34 to the right (Fig. 4), a step-by-step feed movement at a rela tively slow rate may be transmitted, to actuate either of the cross rail'saddles or tool holders when the upper handle 84 of such saddle is moved to engage the feed. Likewise with a clutch hub 37 adjusted to the left (Fig. 4) the power rapid traverse may be engaged for either saddleupon actuation of the lower handle46 o'nisuch saddle, it being noted that there is thus no possibility of the feed and rapid traverse to any feed shaft being engaged at the sametime, and

when the clutch hub 37 is in intermediate position both the feed and rapid traverse are the foregoing description to indicate the scope of the invention.

Having described, my invention, what I claim as new and desire to secure by Letters Patent is:
