Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed August 29, 1904:. Serial No. 222.599

To all whom it may concern:

Be it known that I, SAMUEL MCMILLEN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Planers, of which improvements the following is a specification.

The invention described herein relates to certain improvements in planers, and has for its object a construction and combination of mechanical elements or parts whereby the planer may be usedin the ordinary and usual way for cutting surfaces parallel with the movement of the bed and also may be used for the cutting of surfaces at an angle to the plane of movement of the bed-such, for example, as the cutting of slots or vertical surfaces of articles carried by the bed. When the machine is used as an ordinary planer, the parts required in such operation are driven from one motor, such as belt-driven pulleys;

but when the machine is used for slotting, &c., an independent motor, such as belt-driven pulleys, is employed, the first motor being disconnected.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of my improved planer mechanism. Fig. 2 is an elevation of one side of the same, which will be hereinafter termed the slotter side. Fig. 3 is a similar view of the opposite side of the planer, which will be hereinafter termed the planer side. Fig. 4isasectional plan view on a plane indicated by the line IV IV, Fig. 1, the planer-bed being removed. Fig. 5 is a plan view, partly in section, of the movable rail and the parts carried thereby; Fig. 6 is a sectional view of the rail and one of the heads, the plane of section being indicated by the line VI VI, Fig. 1. Fig. 7 is a similar view of the same parts on a plane indicated by the line VII VII, Fig. 1. Figs. 8 and 9 are views in elevation and section of parts of the mechanism for transforming rotary into a reciprocatory movement for feed purposes. Fig. 10 is a sectional view on a plane indicated by the line X X, Fig. 9; and Fig. 11 is adetailed view showing a pawl-andratchet connection of the pinions with the threaded shaft.

In the practice of my invention the bed 1 is arranged on a bed-plate 2, suitable guidesurfaces being formed in adjacent faces of said parts for properly directing the'move ment of the bed. This bed is provided on its under side with a rack-bar 3, with which the master-wheel 4. intermeshes. This masterwheel is driven through a train of gearing 7 8, and 9 by the shaft 10, which is provided with a gear-wheel 11, intermeshing with a pinion 12 on a shaft 13, as shown in Fig. 4. For slotting purposes this shaft 13 is provided with a pinion 14, driven through a train of gearing by a shaft 15, said shaft being rotated by rack-bar 16,intermeshing with a gearwheel 17 on said shaft. This rack-bar 16 is connected by a pitman 18 to a pin 19, adjustably mounted in ways on a disk 20, as shown in Figs. 8, 9, and 10. This disk 20 is secured to a sleeve 21, surrounding the power drivershaft 22 and a notched Wheel 23, keyed thereon. In order to intermittently connect the disk 20 with the wheel 23, a sliding bar 24 is mounted in guides on the rear face of the disk 20, and a spring 25 is suitably arranged between the bar 24 and the abutment on the disk, so as to tend to draw a finger 26 on the bar into engagement with the notched wheel 23. The inner face of the disk 20 and the outer face of the wheel 23 are held in frictional engagement with each other by springs 27, which are arranged in sockets in the sleeve 21 and yieldingly press the disk 20 against the outer face of the wheel 23. It is preferred to have the springs operate through pins 6, the ends of which project into a collar on the bushing 21, arranged between the shaft and the sleeve 21. The pins 6 engage the collar, so that the bushing will rotate With the sleeve and be capable of movement along the shaft. These springs tend to force the collar and the disk 20 to the left in Fig. 9,

thereby producing the desired frictional en- 24 out of line with a cam-plate 27, and the spring 25 will then be free to draw the finger 26 on the opposite end of the bar 24, as shown in Fig. 9, into engagement with the toothed wheel 23, thereby imparting an oscillation to the rack-bar, and consequently through the connections described to the planer-bed 1. As the wheel 23 continues to rotate, the end of the bar 24 opposite the finger 26 will be brought into engagement with the opposite cam 27 and be thereby shifted to side engage the finger 26 from the wheel 23. A pinion 28 is loosely mounted upon the shaft 22 and is adapted to be connected thereto by the movable member 29 of aclutch, such movable member being keyed to the shaft. When the movable member of the clutch is in engagement with the other member on the pinion 28, the latter and the shaft 22 will be driven through a train of gearing (shown in Fig. 4) by a shaft 30. This shaft is connected by gearing to ashaft 31, having a tight pulley 32 and loose pulleys 33, adapted to be oppositely driven by a straight and cross belt, as is customary. By the shifting of one or the other of these belts a step-bystep movementis imparted through the mechanism described to the planer-bed and also through the rack-bar 16 to a gear-wheel 34, which intermeshes with

pinions

35 and 36, having a pawl-and-ratchet connection to the

shafts

37 and 38 through sleeves having an annular opening for the reception of the ends of the shafts. The

pinions

35 and 36 are loosely mounted on the sleeves, in which are mounted pawls engaging teeth on the pinions, as shown in Fig. 11. The rack-bar 16 intermeshes with a pinion secured to or formed on the gear-wheels 34, said parts being loosely mounted on a stud secured to one of the uprights of the planer. By the movement of these

shafts

37 and 38, which, as shown in Fig. 1, are threaded and mounted upon the rail C of the planer, the saddles A and B are moved back and forth along the rail, said shafts being in engagement, respectively, with nuts 39 on the saddles, as shown in Figs. 6 and 7. By means of these shafts the saddles can be moved back and forth as required. The

ratchet-pinions are so constructed that they can be reversed on the shaft so as to turn the same in opposite directions, as required by conditions of feed of the saddles. It will be understood that by shifting one or both of the ratchet-pinions out of engagement with pinion 34 only one or neither of the saddles will be shifted during the reciprocation of the rack-bar. Rack-bars 40 are mounted in suitable vertical ways in the saddles, as shown in'Figs. 1, 5, 6, and 7, and are provided along one edgewith teeth for engagement with pinions 41, mounted on studs 42, having suitable hearings in the saddles. On the outer ends of these studs 42 are secured upon a stud 45, carried by the saddles.

gearwheels 43, adapted to intermesh with one of a pair of pinions 44, mounted loosely The other member of this pair of pinions is adapted to intermesh with pinion 46 on the shaft 47. The pinions 44 are free to move along the stud 45, so as to connect the

pinions

46 and 43 when it is desired to operate slotting-bars and to move outwardly when the slotting-bars are not in use. The shaft 47 is driven by shaft 43 through a suitable train of gearing, of which the bevel-gears 49 form a part, and said shaft is in turn driven through bevel-gears by shaft 30.

In order to automatically shift the belts, a

suitable reversing mechanism is employed to operate the belt-shifters, a convenient construction of such mechanism being shown in Figs. 1 and 4. This reversing mechanism consists of a worm 50 on the shaft 30, intermeshing with a worm-wheel 51, provided with knockers 52, adjustably mounted on the wormwheel and adapted to strike and shift a lever 53, connected with the belt-shifters.

From the foregoing it will be readily understood by those skilled in the art that the slotting-bars 40, carried by the saddles, can be reciprocated. up and down for the cutting of vertical surfaces, said bars being provided at their lower ends with suitable holders. Provision is made in the manner described for feeding the saddles back and forth step by step, as required by conditions of work. Provision is also made for a back-and-forth movement of the planer-bed for further adjustment of the relative positions of the work and the tool. By the adjustments of the saddles and the planer-bed the tool carried by the slotting-bar can be caused to traverse the work in directions at right angles to each other.

When it is desired to use the planer in the usual manner, the pinion 14 in the train of gearing connecting the

shafts

13 and 15 is removed, thereby disconnecting the

shafts

13 and 15, and at the same time the movable member of the clutch 29 is shifted, so as to engage another member thereof on the gear-wheel on the shaft 22, thereby releasing the gearwheel 28 from connection with said shaft, and thus disconnecting the shaft 30 from bedoperating mechanism. By the removal of pinion 14 and the shifting of the movable member of the clutch all driving connection from the shaft 30 to the shaft 22 is broken. On the shaft 13 are secured tight and loose pulleys 54 with straight and cross belts which i are adapted to be shifted back and forth byany usual form of construction of mechanism, operated and controlled by the movements of the planer-bed. By the rotation of the fast pulleys on the shaft 13 the latter is rotated, and with it the shaft 10, the train of gearing 9, a pinion 56in engagement with the gear-wheel 55. By the operation of this gear-wheel 55 the shaft 22 will be rotated, and through it a reciprocation will be imparted to the rack-bar,57,the connection between the shaft 22 and the rackbar being similar to that described in relation to the connection between the shaft 22 and the rack-bar 16. This rack-bar 57 intermeshes with a pinion connected to the gear-wheel 58, v

having a spline connection with a threaded shaft 65, said shaft engaging a nut 66 on the saddles and connected at one end to a movable front plate 67, whereby the apron 68, carrying the tool, can be adjusted vertically. By changing the ratchet-pinion 59 from the shaft 38 to the shaft 37 one of the saddles can be adjusted along the rail. By changing back the pinion the other saddle can be adjusted as required, and by placing the ratchet-pinion on the shaft 60 the tools carried by the aprons can be raised and lowered as required. These adjustments of the movable plate and saddle are those ordinarily found in planers and the feed movements are step by step as required. In order to get a quick return of the saddles, a gear-wheel 69, mounted ona stud secured to one of the uprights, intermeshes with a pinion 7 O and has attached thereto a pinion intermeshing with the gear wheel 71, loosely mounted on a stud, which also carries gearwheel 34. The pinion is mounted with a freedom of a longitudinal movement on the shaft 47, so as to be moved into and out of engagement with the gearwheel 69. By

shifting this pinion 7 0 into engagement with.

the gear-wheel 69 and throwing on one or the other of the belts driving the tight and loose pulleys 54: or 32 a quick movement can be imparted to the gear-wheel 71 and through it to one or the other or both of the ratchetwheels of the

ratchet

35 or 36, dependent upon which one is to be operated. As the shaft 47 moves continuously in the same direction 11. e. without astep-by-step movementa quick movement of the saddles in either direction can be effected. When this quick movement of the saddles is required, one of the ratchet- .

pinions

35 or 36 is moved along the angular .ends of the

shafts

37 and 38 out of engagement with the gear-wheel 34 and into engagement with gear-wheel 71.

The shaft 22, by which the rack-

bars

16 and 57 are operated, will always be in engagement either with the motor represented by the fast and loose pulleys 32 33 or that represented by the fast and loose pulleys 54, so that these rack bars will always be reciprocating.

Whether or not they will be doing any work will depend upon the use to which the machine is to be applied. By the employment of these two rack-bars a certain speed can be imparted to the shaft 60, whereby the saddle is adjusted up and down and a radically different speed can be imparted to one or the other of the threaded

shafts

37 and 38, and by this means a diagonal out can be. formed.
