METAL PLANER.

Application filed September 12, 1919. Serial No. 323,349.

To all whom it may concern:

Be it known that 1, Lewis M. PYLE, a citizen of the United States, residing at Bryn Mawr, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Metal Planers, of which the following is a specification. I

This invention relates particularly to planers which are so large and heavy that certain of the adjustments thereof cannot be readily made by hand as has been customary. One of the adjustments that has heretofore been necessary to make by hand is the swiveling of the tool carrying devices with respect to the saddles so as to rovide for feeding at any desired angle. ne object of the invention is to provide power operated means whereby the tool carrying devices can be swiveled, these power operated means being under easy manual control.

Another object of the invention is to provide improved feed mechanism adapted to be readily adjusted to provide coarse or fine feeds. As concerns this feature the invention is equally applicable to both large and small laners.

Other ob ectS of the invention will appear from the following specification and claims.

In the accompanying drawings. there is shown the embodiment "of the invention that is deemed preferable, but it is to be understood that various changes may be made without departing from the spirit of the invention as set forth in the claims appended to this specification.

Of the drawings:

Fig. 1 is a fragmentary side View of a planer embodying the invention.

Fig. 2 is a fragmentary front view.

Fig. 3 is a rear view of one of the saddles and associated devices.

Fig. 4 is a side view of the parts shown in Fig. 3, this view being partly in section along the line 4:4.

Fig. 5 is a sectional view taken'along the line 55 of Fig. 3.

Fig. 6 is a horizontal sectional view through the feed mechanism along the line 6-6 of Fig. 7.

Fig. 7 isa side view of the feed mechanlsm.

Referring to the drawings, '1 represents the bed of a planer and 2 the work carrying table which is longitudinally movable along the bed in the usual way. For'reciprocatingthe table any suitable mechanism may be provided, but preferably there is an electric motor 3 which is directly connected with the table and which is repeatedly reversed to drive the table forward and backward. For efiecting the reversals of the motor 3 there is provided a ilot switch 1 which is adapted to be turne by a lever 5. Do 6 and 7 are adjustably mounted on the tab e in position to engage the lever 5 and thus move the pilot switch and reverse the motor.

Positioned at the sides of the bed 1 are uprights'88 and these are connected by an arch 9. Vertically adjustable along suitable guideways on the uprights is a cross rail 10. For effecting vertical adjustment of the cross rail there are provided screws 11-11 which are connected at their upper ends with a transverse shaft 12 by means of bevel gearing 13-13. Any suitable mechanism may be provided for rotating the shaft 12, but as illustrated use is made of an electric motor 14' mounted on the arch 9. The motor is connected with the shaft by means of suitable power transmitting mechanism including a manually operable clutch, these parts not being shown in detail, as they constitute no part of the present invention.

Transversely movable along the cross rail 10 are two tool heads 15 and 16. For moving the tool heads and for controlling them there are provided three shafts 17, 18 and 19 which extend longitudinally of the cross rail and are rotatably mounted therein. The upper and lower shafts 17 and 18 are threaded and are provided with spline grooves and the central shaft 19 is provided with a spline groove for :purposes to be set forth.

If desired, additional tool heads may be mounted on the uprights for vertical movement in the usual way. Such side heads are not illustrated, asit will be sufiicient to illustrate and describe the invention as ap-.

- a saddle 20 which engages -guides 'formedon' plied to the cross heads 15 and 16 The two.

heads 15 and 16 are similar and'a description of one of them, as for instance 15,"will suflice for both. 'As illustrated in a general way in Figs. 1 and 2and in greater detail in Figs. 3, 4 and 5,]ea'ch head includes the crom rail.

Carried by the saddle are tool carrying devices inc uding a bracket 21 which is swiveled for movement about an axis extending in the direction of the table reciprocations. This bracket is held in position and guided by means of tongues 2222 and T-bolts 23--23 enterin a circular T-slot 24 formed in the saddle. he swivel bracket 21 is provided with a guideway which is norbe conveniently turned, the upper p mally vertical and a slide 25 is lineally movable along this guideway. For moving the slide there is rovided a screw 26 which extends longitudinally of the slide and which is bodily movable therewith. The screw has threaded engagement with a nut 27. Means including bevel gearing 28 is provided for manually turning the screw and it will be seen that when the screw is thus turned the slide will be moved longitudinally. Mounted on the slide 25 is a swivel plate 29 which is movable about a pivot at 30. In order that the plate 29 may art thereof is arcuate in form and is prov1ded with worm teeth 31 Mountedon the slide 25 is a worm 32 which meshes with the worm teeth 31. It will be seen that when the worm 32 is rotated the swivel plate will be turned about its horizontal axis of adjustment. Mounted on the swivel plate 29 is a clapper box 33 to which the cutting tool may be secured in the usual manner, as for instance by means of bolts 34-34. The clapper box 33 is connected to the swivel plate 29 by means of a normally horizontal pivot pin 35. The clapper box with the tool can move about this pin, thus permitting the tool to swing out .of engagement with the work during the return stroke of the planer table and to effect relief.

For moving the saddle along the cross rail either preliminarily for purposes of adjustment or during operation for the purpose of feeding, use is made of one of the before mentioned threaded shafts, in this case the shaft 17. Secured to the saddle at the rear thereof is a nut 36 which projects into the longitudinal recess in the cross rail in which several shafts are located. This nutengages the shaft 17. It will be seen that when the shaft 17 is turned the saddle and the parts carried thereby are moved longitudinally along the cross rail. For the other head 16 the construction is similar except that the shaft 18 is engaged so that rotation thereof will move the head.

to effect final adjustment. I -this mechanism comprises a gear 36 splined The shafts 17 and 18 are ordinarily turned by power as will presently. appear. However, in making preliminary adjustments it *is dlfiicult to exactly locate the saddles by means of the ower devices. There is therefore prefer-ab y provided-a mechanism located at each tool head whereby the .head maybe moved manually to a slight extent As illustrated,

on the shaft 17, this gear meshing with a gear 36"." This latter gear can be manually turned by means of a handle applied to a squared shaft 36. 3 v

For movin the slide 25' by power, use ,is made of the s aft 19. Splined on this shaft is a bevel gear 37 which is adapted to mesh with a bevel gear 38, this second bevel gear being rotatably mounted in a bearing in the saddle 20 with its axis coincident with the axis of adjustment of the swivel bracket 21. Connected with the bevel gear 38 is a bevel gear 39 which meshes with a bevel gear 40 connected with the nut-27. .It will be'seen that when the shaft 19 is turned the nut 27 may also be turned with respect to the screw, thus moving the slide 25 upward or downward. Inasmuch as the axis of the bevel gears 38 and 39 is coincident with the axis of adjustment of the swivel bracket 21,

the bracket can be freely adjusted without interfering with the power connection. In order that the same shaft 19 may serve for both heads, means is provided whereby the drive gear 37 for either head may be connected to or disconnected from the correspondmg driven gear 38. As illustrated, the gear .37 is slidable with respect to the saddle under the control ofa hand lever 42. It will be seen that by this mechanism the gear 37 can be brought into or out of mesh with the gear 38, thus completing or breaking the power connection. I

For operating the several shafts 17, 18 and 19 there is provided an improved mechanism which is mounted on one end of the cross rail. This mechanism preferably receives its power from an independent electric motor, which motor may be the aforesaid motor 14. As illustrated, there is provided a shaft 43 which extends transversely of the planer and which is directly geared to the motor 14. By means of bevel gearing at 44 this shaft is connected with a vertical shaft 45 adjapent one end of the cross rail. Splined on the shaft 45 and vertically movable with the cross rail. is a bevel gear 46 which meshes with a bevel gear 47 on a horizontal shaft 48 rotatably mounted in a casing 49 carried by the cross rail. This shaft 48 constitutes the initial power ele ment on the cross rail.

For effecting intermittent feeding the following mechanism is provided. Secured to "insurer f adapted to engage the teeth oia gear 56 ro-' tatably mounted on the shaft 54:. It willbe seen that when the shaft is rotated, the bell crank 53 is given an oscillatory movement and the bell crank by means of the pawls 55 serves to turn the gear56 intermittently. The gear 56 constitutes an intermittently operating power feed element.

The gear 56 meshes with a gear 57 loosely mounted on a shaft 58 parallel with the shaft 54. Rotatably mounted on the shaft 57 and is a-third gear 61.

54;- is a gear 59, this gear being adjacent the gear 56 and connectible therewith. The gear 59 meshes with a gear 60 loosely mounted on the. shait-58. l't will be observed that the gear 59 is smaller than the gear 56 and that the gear 60 is larger than the gear 57.-

Mounted on the shaft 58 between the gears This gear is slidably mounted on the shaft and is movable under the control ofa hand lever 62. Clutch teeth 63 are interposed between the gears 57 and 61 and similarclutch teeth 64; are interposed between the gears 60 and 61.

' It will be seen that, in acordance with the present invention, there are two'difi'erently speeded trains of power transmitting devices between the power element or gear 56' and the ear 61 and that the last said gear 61 can be turned at each actuation of the gear 56 through a relatively large angle by means of the clutch teeth 63 or through a relatively small angle by means of the clutch teeth 64-.

one end the gear 61 meshes with a gear 65 mounted on a shaft 66, this shaft also carrying a gear 67. Rotataoly mouiited on a shaft 68 are two similar gears 69 and 76 which mesh respectively with the aforesaid gear 67 and the aforesaid gear 61. The gear 69 meshes with gears 71, 72 and 73 loosely mounted respectively on the shafts 17, 19 and 18. The other gear 70 meshes with similar gears 74, and 76 also mounted respectively on. the said shafts 17, 19 and 18. From a study of the gearing which has been described, it will be seen that the two gears 69 and 70 are rotated in opposite directions and thatthe sets of gears 71, 72 and 73 and 7t, 75 and 76 will also be rotated in opposite directions. Mounted on each of the shafts 17, 19 and 18 is a clutch element 77 adapted to be moved by a hand lever 7 8. Each clutch element is splinecl on its shaft, as for instance 17 illustrated in Fig. 6, and it can be engaged either with the gear 71 or with the gear 74:, thus connecting the shaft for rotation in either direction as desired- When the mechanism is to be used for feeding, the shaft t5 is given one com lete revolution at the end of each table reciprocation, this being preferably brought about by operating the motor to a definite extent by suitable electrical controllin devicesoperated by the planer table. t each such revolution ot'the shaft 45 the gear 56 is ro-- tated through a definite angle which angle can be varied by chan' 'ng the adjustment of the crank pin 51. are moved in opposite directions. through. definite angles corresponding to the angle of movement or the gear 56, the extent of he gears 69 and 70 movement being adjustable by moving the gear 61 to engage and disengage the clutch teeth 63 and 65. Thus the gears 71, 7 2 and 73 are turned in one direction and the gears 74:, 75 and 76 are turned in the other directron. By properly adjusting the several clutch elements 77,the several shafts 17 19 and 18 can '0 turned in either direction as desired, thus eilecting transi' erse feeding of either head in either direction or effecting vertical feeding of either or both of the tools in either direction.

F or continuously moving the tool heads or the tools to effect preliminary adjustments the following mechanism is provided. Secured to the. aforesaid shaft as is a gear 79 which meshes with an idler gear 80 which idler gear in turn meshes with a gear 81 loosely mounted on the aforesaid shaft '54: and constituting a driving element for use during preliminary adjustments. lit will be seen that when the shaft 45 is continuously rotated, the gear 81 is also continuously rotated. it will be observed that the gear 59 is located between the gears 56 and 81.. Clutch teeth 82 are interposed bet-ween the gears 56 and 59 and similar clutch teeth 83 are interposed between gears 81 and 59. The gear 59 can he moved longitudinally by means of a hand lever at to engage the teeth at 89? or the teeth at 83 as desired. Thus the gear 59 can be caused to rotate intermittently with the gear 56 or continu ously with the gear 81.

V7 hen the mechanism is to be used for the preliminary adjustment of the tool heads, the clutch teeth at 83 and also those at 6% are engaged and the shaft 45 is operated continuously. The several gears71, 72 and 73 and 74's, 75 and 76 are then rotated contlnuously but in opposite directions. By properly adjustin the clutch elements 77 any of the shafts 1 19 and 18 can be turned a erably operated by the power feed mechaall nism which serves to move" the saddle and the tool carrying devices in the way already described. As illustrated, use is made of the before mentioned shaft 19. Mounted on this shaft is a worm 85 whichmeshes'with a Worm wheel 86 mounted on the saddle and rotatable about an axis parallel wit-h the axis of adjustment ofthe swivel bracket. Connected with the worm wheel 86 is a pinion 87. This pinion 87 meshes with gear teeth 88 formed. on the bracket 21. It will be seen that when the worm wheel 85 is rotated by means of the shaft 19, power will be transmitted to rotate the gear 87 and thus turn the bracket 21 and the parts carried thereby. In order that the movement of the swivel bracket may be manually controllable, there is provided a clutch 89 between the shaft 19 and the worm 85. Preferably use is made of the before mentioned slidable bevel gear 37, clutch teeth being formed thereon at 89 which are adapted to be moved into or out of mesh by the before mentioned lever 42. Thus the same hand lever serves either to move the gear 37 into mesh with the gear 38 for the vertical movement of the slide 25 or serves to engage the clutch teeth at 89 for the swiveling of the tool carrying devices.

It is difficult to secure exactly the desired adjustment by means of the power mechanism and there is therefore provided manually operable means whereby final adjustment may be effected. For this purpose there is provided a gear 90 connected with the worm 85, this gear 90 meshing with a gear 91. Gear 91 may be turned manually by means of a handle applied to a shaft 92.
