VERTICAL PLAN ER.

SPECIFICATION forming part of Letters Patent No. 601,580, dated March 29, 18.98

Application filed May 9, 1896. Serial No. 590,900. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK B. MILES, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Vertical Planers, of which the following is a specification.

The main object of my invention is to construct a vertical planing-machine in such a manner that it will either plane in a vertical path or in a horizontal path by simply changing the feed mechanism, as fully described hereinafter.

My invention further relates to details of construction fully described hereinafter.

Referring to the accompanying drawings, Figure 1 is a face view of my improved machine. Fig. 2 is an end view looking in the direction of the arrow, Fig. 1. Fig. 3 is a plan view. Fig. 4 is an enlarged plan view of one portion of the machine. Fig. 5 is a section on the line 5 5, Fig. 4. Fig. 6 is a view looking in the direction of the arrow, Fig. 4:. Fig. 7 is a sectional view on the line 7 7, Fig. 8, of the tool-carrier. Fig. 8 is a side view of the tool-carrier. Fig. 9 is an end view of the tool-head.

A is the bed of the machine. At one side of this bed is the table A, having grooves. On this table is clamped the work to be planed. Projecting upward from the base A is the frame A on which are the longitudinal slideways a a. for the carriage B, Fig. 1. This frame is braced at the back by piers A as shown in Fig. 3.

The carriage B has slides adapted to the ways a a of the usual form, being simply undercut, so as to hold the carriage in position. In the ways a a are longitudinal screws 0 0, adapted to a bearing a at each end of the frame A and these screws are geared to a vertical shaft-O by bevel-gearing 0, so that when the shaft 0 is turned the screws 0 will turn in unison. The screws 0 c are adapted to nuts on the carriage, so that when the screws are turned thev carriage will travel across the face of the frame A The carriage B extends a considerable distance above the frame A as shown in Fig. 1, and adapted to this carriage is a vertical screw e, mounted in bearings 19 b on the carriage, and this screw is driven through the bevelgears e by a splined shaft E, adapted to bearings in the base of the machine. Adapted to a vertical slideway b is a tool-carriage D. This tool-carriage has a nut with which the screw e engages, so that when the screw is turned the tool-carriage will be moved in a vertical line.

The shafts O and .E are so geared to the mechanism for feeding and traversing the tool that when it is wished to plane in a vertical line the traverse mechanism is geared to the shaft E and the feed mechanism is geared to the shaft 0; but when it is desired toplane in a horizontal line the clutch mechanism is shifted so that the shaft E becomes a feedshaft and the shaft 0 a traverse shaft. The mechanism is readily changeable at a moments notice.

Connected to the tool-carriage D are cords or chains b which pass over sheaves b on the carriage B and are attached to a counterbah ance-weight 19 within the frame of the, carriage B, as shown in Fig. 3.

F is a belt-shifter rod adapted to bearings ff on the frame A and situated in the pres ent instance directly under the lower slideways a. On this belt-shifter rod is a lever f, Figs. 4 and 5, which is connected to a twoarmed lever F by a rod f. This lever F is pivoted at f to a bracket on the frame of the machine. The lever f is slotted longitudinally, and adapted to the slot is a pivot-block f", which can be adjusted and locked in anyposition on the lever. The rod f is pivoted to the block, as shown in Fig. 4. One arm of the lever F is connected to a belt-shifter F by a rod f. This belt-shifter is of the ordinary construction and is adapted to shift two.

belts in one operation.

The driving-pulley on a shaft G, adapted to bearings on the frame of the machine, is made in the present instance with two faces g g one less in diameter than the other, and on each side of the pulley G are the loose pulleys g and g The belt-shifter is so arranged that either one or the other of the belts can be shifted from its loose pulley to the fast pulley without disturbing the other belt,as will be readily seen by referring to Fig. 4 of the drawings.

On the belt-shifter rod F are twoadjustable sleeves f having friction-rollers projecting in the path of two cam-faced shifters b on the carriage B. One shifter is at the front of the carriage and the other at the back, so that when the carriage has reached the limit of the forward movement the shifter b strikes the roller on the sleeve secured to the shifter-rodand turns the rod in its beartion is repeated when the carriage reaches the limit of its return stroke. from the pulleys on the counter-shaft G to The belts pass the pulleys on the shaft G, Fig. 2, and it will f be noticed that the pulleys are ofdifferent diameters, so as to provide for a slow forward feed and a quick return.

When the carriage B is fed to move the tool to a new path, then the sleeve 7' of the shifter-rod F is moved, so as to be clear or the shifter-cams on the carriage B', and the carriage D then becomes the shifter. To accomplish this, I mount on projections of the carriage B levers h, which carry theshifter- I rod H, and this shifter-rod is connected at its lower end to a lever h, splined to the shifterrod F, so that while the lever will turn the shifter-rod F it will slide upon it with 'the carriage. This shifter-rod H is counterbaL anced by the Weights 71, of the levers h. EX- tending throughout the length of the rod is an undercut groove, to which arefadapted the blocks'lfi. ing to the work to be planed, so that the car- These blocks are adjusted accordriage B will strike the upper blo kin its upward movement and shift the belts through the rods II and F and belt-shifter F and when the carriage reaches its lowest position it will strike the lower block and again'shift I the belt.

shaft G through bevel-gearst' t i The bevelgears 01. are splined to the shaft. G and are adapted to be moved into and out of gear with the bevel-wheel 'i by means ofa lever I,which carries a segmental shoe iiadapted to a groove in the hub of the bevel-wheels z" h The lever I is'a han dle-lever and has a pin 2, adapted to openings ina fixed segment 1 sothat it can be adjusted and locked with either of the bevel-pinions i i in gear with wheels '5 or locked out of gear.

"As shown in the drawings, the lever 'I is connected by arod't to the "pivot f 'of the rod: f which slides in ways inthe face of the lever F", so that when it is wished to cut on the ordinary return stroke it will shift automatic-,

ally, so that the advantage of the slow.feed

and quick'return is gained and the machine is adapted to cut in either direction at the.

proper speed with quick return.

is mounted'a bevel-pinion J. These pinions are shouldered, so'that they will'not'move 1ongitudinally in their bearings. Each pinion has two clutch-faces, one at the forward end and one at the back. Adapted to engage with the forward clutch-face of the pinion J is a clutch K,mounted on the shaft I, and adapted to engage with the forward clutch-face of the pinion J is a clutch K. Also on the shaft I and mounted between the two pinions is aclutch Kihaving two clutch-faces, one adapted to engage with the rear clutch-face of one pinion J and the other clutch-face adapted to engage with the face of the other pinion J. This clutch K -has gear-teeth on its periphery meshing with. the teeth of a wheel L, mounted on a stud L, carried by a bracket 6%. The shaft I is hollow for a certain distance, and mounted in this shaft is a shifter-rod K which is connected to the several clutches K K K the clutches K K being connected to the rod bypi'ns which pass through elongated slots in the shaft I.

I The hub of the clutch K is mounted between the headk of the rod and acoll'ar, so that there is a certain amount of lost motion in the movementiof the rod before this clutch is acted upon. A'spring is mounted in the head 7 of the rod, so that the levercan be shifted, and the clutches will go into place as the teeth'come in line.

The head of the rod K is connected to a handled shifting leverK, which can be locked in any position by a lever engaging the notches of a segment 70*, mounted in a standard k secured to the base of the machine.

The clutch K isloose on the shaft I, so that the motionof the shaft is not imparted to this clutch, but is simply imparted to the clutches K and K, the clutch K being driven by the tool-"feeding mechanism M through the wheel L, the shaft I being the medium through t which the traversed motion is given to the Referring. now to Figs. at, 5, and 6, in the bed ofthe machine is a shaft I, geared tothe slide or tool-carriage, so that it will be seen that when the leverK is in the mid-position, Fig. 5, all the clutches are outof gear and the mechanism is at a standstill; but when the lever is shifted in the direction ofthe arrow, 'Fig. 5, it'tln owstheclutch K into gear with the pinion J and the clutch K into gear with the pinion J,and as the pinion J meshes with a bevel-wheel] on the shaft 0 and the pinion J meshes with a wheel j on the shaft E the slow feed motion is imparted to the shaft E and the traverse motion imparted to the'shaft C, the'clutch K being out of gear; but when the lever is shiftedfin the opposite direction the clutch K is thrown out of gear, while the clutch K is thrown into gear with the pinion J and the clutch K thrown 'into gear with the'pinion J, so that the slow feed motion is imparted to the shaft 0 and the traverse motion is imparted to the shaft E.

The traverse motion M shown, Fig. 4, has been used by me for feeding ordinary'planers, &c., the shaft 'M being geared to the shaft G through this motion, as clearly shown in'Fig. 4. 0h the'end of the shaft M is a slotted arm M and adapted to this arm is ahead nu'which can be adjusted in the slot by a screw m, so

as to alter the distance between the pivotpin on the head and the center of the shaft. This head is connected by a rod m to an arm L mounted in the present instance on the hub of the Wheel L. Carried by this arm is a spring-pawl Z, which engages with the ratchetteeth on the rim of the wheel L, so that as the feed mechanism revolves the shaft M the arm L moves the wheel L forward a certain number of teeth and returns as the shaft M continues its motion. Thus it will be seen that the feed of the tool can be regulated by adjusting the head m on the arm M When it is required to move the feeding mechanism by hand, a handle is placed on the shaft L which has a pinion Z gearing with the wheel L, so that by turning this shaft L the tool can be readily adjusted.

On the tool-carriage D, Figs. 7, 8, and 9, is a tool-slideD, adapted to be adjusted in Ways by a feed-screw p. Mounted in the cylindrical socket of this toolslide is the shank D of a head D The shank D is held in the adjusted position by the clamp-bolts d. A collar 01 can also be used if necessary. The shank is made cylindrical, so that the tool can be adjusted to cut in either of four positions, according to the character of the work, and the head can be moved out to reach places ordinarily inaccessible.

In the head D is a circular opening having undercut edges, and secured to the head is a semicircular flange d held in position by screws (1 and confined in this circular opening is the circular base d of the tool-head D Carried by the tool-head is a tool-carrier D adjustable on the tool-head by means of the screw d The carrier has the usual tool-posts d, by which the tool is fastened to the head.

By the above arrangement the tool can be universally adjusted on the carriage D.

The feed-screwp is geared to a shaft p by bevelgears p 9 and on the shaft 19 is a ratchet-leverp, having an arm 13 connected by a rod qto a feed-lever Q, whiehis slotted, and adapted to, the slot is a block q, so that by adjusting the block in the slot the feed can be increased or diminished in either direction. The leverQ has an arm g connected by a rod Q3 to a lever Q, pivoted to the frame of the machine at g and on this lever are two rollers which are arranged on each side of the bar H, so that when the bar is moved it will feed the screw a certain distance. The screw can be operated by hand by reciprocating the handle 10 It will be seen by the above description that the machine as described makes it possible to either plane from the right or the left with a slow forward traverse and a quick return, or from the bottom to the top or from the top to the bottom with a slow forward traverse and a quick return.
