To all whomc't may concern: i

Be it known that I, CHARLES Gnonen JoHANNEsMEYER, a citizen of the United States, residing in Glendale, Hamilton county, Ohio, have invented certain [new and useful Improvements in Planer Feed Devices, of which the following is a specification. l I

This invention, while useful in-othersituations, has been devised primarily as a device for use in connection with the feed of metal planers, and the invention will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1 is an end'view of a planer-rail provided with an embodiment of my improved feed-device, a removable portion of the casing-cover being omitted, and the main casing appearing in vertical section in the plane of line 0 of Figs. 2 and 3.

Fig. 3 avertical section of a portion of the feed-device in the plane of line a of Figs. 1 and 4: p

gig. 1 a plan of a portion of the device: an

Fig. 5 a vertical section of the clutchg irowing lever' in the plane of line b of i diversity of scalesis employed in the drawing. 1

In the drawing 1, indicates the end ofthe planer-railf 2, one of the feed-screws of the rail:

3, the other feed-screw of-the rail, present on the assumption that the rail carries two heads:

4, the feed-rod of therail:

5, a casing secured to the end of the rail and serving to cover mechanism'thereat:

6, the usual splined shaft for bringing the feed-motion from the -lowerr works of the planer up to the end of the rail: H V l 9 7, a driving-gear oscillated by theoscillation of the splinedshaft: and I 8, pinions' loose upon the outwardly projecting portions of the feed-screws, and feed-rod and gearing with eachother, the intermediate one of them engaging the ear As thus far described the device may have the usual form and mode of operation. It is the duty of the splined rod 6 to turn a measured degree in one direction and then the selected instance 2 r of this collar: 1

the same degree in the reverse direction, this motlon of the spllned rod glvlngto gear 7,

to which the 'rod is-bevel-geared,- asimilar motion of oscillation, and the gear? giving to the-pinions 8 the same motion of oscillation. Usually the pinions are pawl and ratchet devices, or s'o-called cliclcboxes, which can beadjusted to cause the oscillation of the pinions to become efli'ei'etive upon their feed screws or feed-rod in selected direction, or tobe neutral. The present device presents a construction for the pinions to endow them with pawl andratchet quality, and as the three pinions arealike particular description need be given to but one of them, and it is to be taken as understood thatthe shaft to which the described pinion pertains is either the feed-rod or feed-screw, in other words, a shaft, threaded or otherwise, to be rotatively advanced intermittently.

Proceeding with the drawing 9, indicates a counterbored collar capable ofsliding on the shaft, the feed-screw 2 in 10, facial ratchet-teeth 11, a pin through the shaft, its projecting ends being straddled by notches in the counterbored end of the collar so that the collar may slide but not turn upon the shaft:

12,a springdisposed inthe counterbore V of the collar and acting compressively between the pin 11 and the bottom of the counterbore 13, a second counterbored collar with its face spaced apart from that of the collar 9:

14, facial ratchet tee th upon the second collar, these teeth being arranged to ratchet in the direction opposite that of teeth 10:

15, a pin for the second collar:

' 16, a spring for the second collar:

:17, an enlargement fast upon the shaft 1 between the 7' two collars and limiting the approachof those collars toward each other under the influence of their springs, this enlargement being illustrated in the present instance as a thimble separably pinned upon the shaft:

18, a hub of some length at one side of the pinion 8, this hub being bored to turn and slide upon the collar 9:

19, a circumferential groove in this hub:

20, a collar fast within this hub and adapted toslide onthe enlargement 17, and

formed on one end having each of its ends provided-with facial ratchet-teeth to cooperate with the ratchetteeth of the collars 9 and 13:

21, a counterbored hub removably secured to the shaft and adapted to cooperate with the casing in protecting the collar 13, these hubs 21 being provided with a circumferential series of graduations to measure the angular rotation of the shaft, particularly when the shaft is turned by hand:

22, a bearing secured removably to the wall of the casing in front of the shaft to Which the pinion pertains:

, 23, a cylinder fitted to turn in this bearing;

24, a lever secured to the outer end of th1s cylinder:

25, a block adapted to fit sidewise in the groove 19:

26, a cylindrical shank of this block, fitting an eccentric bore in the cylinder 23: and

27 a spring detent adapted to engage countersinks in the periphery of the cylinder and yieldingly hold the lever 24in either of 1ts extreme positions or in its neutral position.

Enlargement 17, which is separably pinned to the shaft, is made in the manner indicated merely to facilitate the construction and assembling of the parts, the purpose of this enlargement being simply to limit the inward movement of the ratchet collars 9 and 13. 7

As the parts appear in Fig. 3 the pinion together with its hub and its collar 20 are in neutral endwise position and the pinion may make its oscillations without effect upon the shaft. But if the pinion be shifted to the left, and there held, then the teeth at the left end of collar 20 will engage the teeth 10 of collars 9, and thereupon the oscillating motion of the pinion in one direction will be transmitted to the shaft, while upon the occurrence of the oscillating movement of the pinion in the other direction the engaging teeth will ratchet past each other, collar 9 moving to the left against the resistance of its spring, and no motion will be given to the shaft. The result is that the shaft will be advanced, clockwise, intermittently. If, however, the pinion be shifted to the right, then the intermittent advance of the shaft will be effected through the medium of collar 13, and the shaft will be turned intermittently in non-clockwise direction. Analysis of the toothed collars 9 and 20, considered as a couple, will show that the teeth constitute, in effect, a pawl and ratchet, and that the performance would be the same if all of the teeth, except one, were omitted from one member of the couple. And, similarly, as regards the couple formed by collars I 20 and 13.

The graduated collar 21 serves in protecting projecting parts and also serves in indicating the measure of rotative advance of .the first-mentioned collar,

the shaft while it is being turned either by the oscillation of the pinion, or by hand.

Normally the handle 24 is vertical and held so by the spring detent, and in this position the ratchet collar 20 is neutral, and no rotation is transmitted to the shaft. If the handle 24 be turned a quarterway to the right, where it will be again held by the spring detent, the block 25, fitting the groove 19 in the pinion, will cause the shifting and holding of the pinion to the right so that the oscillations become effective upon ratchetcollar 13, and the shaft be turned intermittently in non-clockwise direction. If the handle be turned to the left, then the ratchet-collar 9 becomes the effective one and the shaft becomes turned intermittently in clockwise direction. Assuming the shaft to be a righthand feed-screw then the direction of the handle 24 indicates the direction of feed of the part moved by the feed-screw. The pinion can be thrown to the right or to the left or to the neutral while the parts are in operation, a result not conveniently attainable with the usual arrangement where the pinion is a click-box carrying a pawl. The bearings 22, for the eccentric cylinders, are flanged and removably secured to the front wall of the casing.

It is to be understood that the construction of the device particularly set forth constitutes but a single excmplification of my invention, my intention having been to set forth the principle of the invention and the best mode in which I at present contemplate 100 applying that principle.
