Specification of Letters Patent.
Patented Oct. 3, 1905.
Application filed July 18, 1903. Serial No. 166,089.
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 Iennsylvania,have invented or discovered certain new and useful Improvements in Planers, of which improvements the following isaspeciiication.
The invention described herein relates to certain improvements in slotting attachments for planers. and has for its objecta construction of mechanism whereby a reciprocating bar or slotting tool-carrier may be secured to the saddle of a planer and operated by or from an independent motor or the usual operating devices of a planer.
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 a planer having my improvement applied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation, on an enlarged scale, illustrating the slotting attachment and its operating mechanism. Fig. 4 is a front elevation of the parts shown in Fig. 3. Fig. 5 is a view in elevation of the beltshifting mechanism. Fig. 6 is a side elevation of the same. Fig. 7 is a sectional elevation of the reversing mechanism for the beltshifter. Fig. 8 is a view similar to Fig. 1, illustrating a modification of my improvement. Figs. 9 and 10 are elevations of opposite sides ofthe construction shown in Fig. 8. Fig. 11 is a sectional plan view of such construction. Fig. 12 is a sectional detailed view of a portion of the frictional feed mechanism.
Figs. 13 and 1a are detailed views of the feedpinion and its pawl; and Figs. 15 and 16 are detailed views, in section and elevation, of a modification of the frictional feed mechanism.
In the practice of my invention the planer is constructed in the usual or any suitable manner as regards the reciprocating bed 1, the uprights 2, the adjustable cross-head 3, and the mechanism for operating the crosshead and bed. As is customary, one or more saddles 1 are movably mounted upon the cross-head, said saddles being adapted to support and hold the tool-rests, &c. In applying my slotting attachment the tool-rest is removed from the saddle 4 and a plate5 is bolted thereto. This plate or bed 5 is provided with suitable guideways for the rackbar 6, which is provided at its lower end with suitable means whereby a slotting-tool may be attached. The vertical reciprocation of the bar 6 is efiected by a pinion 7 on a shaft mounted in bearings 8 on the plate 5 and having secured thereon a gear-wheel 9, intermeshing with a pinion 10 on a shaft 11. As shown, this shaft 11 is mounted at its ends in bearings 12, secured upon the cross-head 3, so as to move therewith, and the pinion 10 is so secured to the shaft as to be free to move along the same while rotating therewith. A pinion 13 is keyed to the shaft 11 and intermeshes with a similar pinion 14 on a countershaft carrying a beveled gear 15, intermeshing with a beveled pinion 16, journaled in a bracket 17, and adapted to be driven by a vertical shaft 18, the connection between the beveled pinion 16 and the shaft 18 being such as to permit the pinion to slide along the shaft, but to rotate therewith. The lower end of the shaft 18 is provided with a beveled pinion 19, intermeshing with a corresponding pinion 20 on the shaft 21. Theshaft 21 can be driven in any suitable manner-as, for example, by means of beltsas shown. On the shaft 21 are mounted two pairs of pulleys 22 and 23, one pulley of each pair being loosely mounted, as is customary in planers. These pulleys are adapted to be driven in opposite directions by cross-belts from any suitable motor, as is the practice; but any other suitable means whereby a reversal of the rotation of the shaft 21 can be efiected may be employed.
When employing the driving mechanism shown, a reversal of the movement of the parts is effected by shifting one of the belts from the fast to the loose pulley and the other belt from a loose to afast pulley by suitable beltshifting mechanism operated by suitable means at the end of certain predetermined movements of the rack or tool bar of the slot ting device. A suitable construction to this end is shown in Figs. 5, 6, and 7 and consists of a worm on the shaft 21 engaging with a worm-wl1eel25 on a vertical shaft 26. On this shaft are mounted arms 27 and 27*, adjustable as regards their angular relation to each other and provided with pins 28, projecting downwardly and adapted to strike against the pin 2i) on an arm 30, projecting from the sleeve 31, sum-minding the shaft 26. To this sleeve is secured an arm 32, having its outer end connected to belt-shifting mechanism of any suitable form or construction whereby the belts may be moved from the fast to the loose pulleys, and vice versa. It will be readily understood by those skilled in the art that by changing the angular relation of the arms 27 and 2T a greater or less move ment can be imparted to the reciprocating rack or tool bar 6 before reversal occurs.
In order to effect a lateral feed of the saddles and the parts carried thereby, a pinion is secured on the counter-shaft carrying the beveled gear and intermeshes with a gear-wheel 34, which is loosely mounted on a hub between disks 36 ant 37, carried by the hub, the latter being loosely mounted on a counter-shaft 38, as shown in Figs. 12 and 15. The pressure, and consequently the frictional engagement of these disks with the gearwheel 34, is regulated by means of nuts screwing on the hub to force the disks more or less tightly against the body of the gear-w heel. A pinion 39 is carried by the hub 35 and intermeshes with gear-wheel 40, loosely mounted on a counter-shaft, carried by the crosshead., This gear-wheel is adapted to intermesh with a pinion 41, having a pawl-andratchet engagement with a hub 42-, which is adapted to be placed upon the angular ends of the threaded shafts 43 and 44, whereby the lateral movement of the saddles 4 on the cross-head is effected. As shown in Figs. 13 and 14, the pinion 41 is loosely mounted on the hub 42, but can be locked thereto by a reversible pawl 61. These shafts 43 and 44, together with the shaft 45, whereby a vertical feed of the ordinary tool-head can be effected, are arranged, as clearly shown in Figs. 3 and 10, in the arc of a circle whose center correspoluls with the center of rotation of the gear-wheel 40, so that said gear-wheel may be employed for operating any one of these respective shafts by shifting the hub 42 with its pinion 41 onto the end of the shaft to be operated. In order to limit the lateral feed movement of the saddles, an arm 46 is secured to a bracket on the cross-head and projeets into the paths of movement of steps 47, carried by the disk 36 and adjustably mounted thereon. When one or the other of these steps comes into contact with the arm 46, the movement of the disk and the hub carrying the same will be checked, while the gearwheel 34 will befree to rotate between them. As the pinion 41 has a pawl-and-ratchet engagement with the hub 42, the shaft carrying said pinion and hub will be fed only when the pinion is rotated in one direction, so that a step-by-step feed of the saddles can be effected. By shifting the arm 46 out of the path of movement of the stops any desired rotation of the shafts 43, 44, and can be had, thus utilizing power-driven mechanism for shifting the saddles or tools carried thereby.
In lieu of employing an independent motor for driving the slotting attachment and the saddle-adjusting mechanism the power mechanism employed for operating the planer-bed can be utilized for that purpose, as shown in Figs. 8. 9, 10, and 11.. To this end the arm 32 on the sleeve 31 is detachably connected to the ordinary belt-shifting mechanism of a planer-bed, said mechanism being also connected to the rod 48, employed for transmitting motion from the plamar-bed to the belt shifting mechanism. As shown in Figs. 10 and 11, the shaft 49, on which the two pairs of fast and loose pulleys are arranged, is connected by beveled pinions 19 and 20 with the vertical shaft 18, through which the slotting attachment is driven, by the mechanism hereinbefore described. The shaft 49 extends across the planer under the bed and has a pinion 50 loosely mounted on the shaft, but adapted to be connected with the shaft by a clutch mechanism 51 when it is desired to operate the bed 1. This pinion intermeshes with a gear-wheel 52 on a shaft which forms a portion of the mechanism usually employed for reciprocating the planer-bed.
A bevel-pinion 53 is keyed to the shaft 49 and intermeshes with a similar pinion on the counter-shaft 54. which is provided with a worm intcrmeshing with the worm-wheel on the vertical shaft 56. This shaft is connected by beveled pinions 57 with a countershaft 58, on which is keyed the hub of disk 59, arranged between two clamping-plates 36 and 37, one of which, as 36, is provided with a peripheral flange and with a hub 35, loosely mounted on the hub of the disk 59. The disk 37 tits within the flange of the plate or disk 36, and the disk 09 is clamped more or less tightly between the plates or disks 36 and 37 by adjusting the latter by an annular screw 60, operating in threaded sockets formed partially in the periphery of the disk 37 and the flange on the disk 36, as shown in Fig. 15. A pinion 39 is keyed on the hub of the disk 36 and intermeshes with the pinion 40, engaging in turn pinion 41. As heretofore described, the pinion 41 has a pawl-and-ratchet engagement with a hub 42, adapted to be placed on either one of the shafts 43, 44, or 45, thus enabling either one of the shafts to be powerdriven in either direction by reversal of the position of the belts and the pawl 61. As shown in Figs. 13 and 14, the pawl 61 is so mounted in the hub 42 that by drawing it outwardly a short distance it can be reversed, the tooth on the pawl and those on the pinion being so shaped'as to operate in the desired manner with the pawl in either position.
