.linois Application December 26, 1928. Serial No. 328,436. Renewed July 28, 1932 Claims.
This invention relates to mining machines and more particularly to machines of the mounted type having a projecting kerf cutting element adjustable in varying positions relative to the main 5 frame for making various cuts including top or bottom slabbing cuts or side shearing cuts.
A prior application, Serial Number 153,253, filed by me on December 8, 1926, relates to a mining machine of the class described. This invention is an improvement overmy prior invention in that I provide an improved means for vertically raising and lowering my cutting element giving a greater range of adjustment thereof and provide a more simplified gearing arrangement than is shown in my prior application.
Other objects of the invention will appear from time to time as the specification proceeds.
The invention may be best understood with reference to the accompanying drawings wherein:
Figure 1 is a side View of the machine showing the cutter bar disposed at the opposite side and projecting forwardly from said machine, indicating bydotted lines certain other permissible positions of said cutter bar;
Figure 2 is an enlarged plan view of the machine main body with parts broken away and in section to more clearly show the details of my invention;
Figure 3 is an enlarged vertical longitudinal section of the cutting element of the machine;
Figure 4 is an enlarged side view of the machine main body with parts broken away and in section to more clearly show the means for verticallymoving the cutting element in its guides;
and
Figure 5 is an enlarged plan view of the machine truck with parts broken away and in section to more clearly show the truck driving means and the driving means for vertically moving the cutting elementlin its guides. I i 7 Like numerals refer to like parts throughout the various figures- Referring now to the details shown in the drawings, the main elements of the machine include a cutting element generally indicated at I mounted on guide members 2, 2, extending vertically upward from a base frame 3 so said cutting element may be moved vertically in said guides with respect to said base frame. Thebase frame 3 is mounted on a pair of continuous tread mechanisms 4, 4, for moving the machine from place to place andin and out of cutting position, which continuous tread mechanisms are interchangeable with a set of track guided supporting wheels 5, 5.
Referring now in particular to the cutting element 1, said cutting element includes a main body portion 6, a cutterhead generally indicated at 7 projecting forwardly from said body portion and rotatably movable about a longitudinal axis with respect thereto and a cutter bar 8 projecting forwardly from said head and pivotally movable in aplane parallel to the axis of rotation of said head. The cutter bar 8 carries an endless cutter chain 9 of the usual form adapted to ride in suitable guides 10 formed about the sides and end of said cutterbar in theusual manner. Referring in particular to Figure 1 it may be seen that the "cutter bar 8 may be bodily rotatedrelative tothe main body portion 6 on an axis exten'dinglongitudinally of the latter and may be rotated on an axis perpendicular to said longitudinal axis as indicated by dotted lines in said figure to cut in various planes with respect to said body portion. The main bearings for the cutter head! comprise a cylindrical neck 14 journaled in a bearing g 15 formed at the front end of the main body portion 6 and an auxiliarybearing member 16 journaled in a cylindrical outboard bearing support or ring 17 connected to themain body portion 6 by a suitable rigid frame member 18 as is best shown in Figures 1, 2 and 4. The main cutter head bearings 15 and 17 are preferably oftthe split type; as for instance, being divided on a. horizontal plane so as to comprise base members 15a. and 17a with their respective cap members 15b and 17b, respectively. Said bearings 15 and 1'7 together form in effect trunnions for thecu tter head '7 disposed forwardly and rearwardly of the point of connection of the cutter bar 8 to said cutter head. i i i A cutter bar supporting member 19 is mounted on the cutter head '7 midway between the cutter head bearings 15 and 17 to rotate on an axis perpendicular to the longitudinalaxis of the cutter head 7 and has the cutter bar8'fixed thereto by any suitable means well known to the art. A segment of a gear 20 is fixed to the cutterbar supporting member 19 and projects forwardly therefrom. A pinion 21 on a transverse shaft 22 meshes withthe gear segment 20 for moving said gear segment and the cutter bar supporting member 19 about its pivotal axis. The shaft 22 and pinion 21 are driven from a motor 23 on the rearward end of the body portion 6 through a suitable system of gearing which will hereinafter be de- The cutter chain 9 isdriven by. a sprocket 24 on the outer end of a shaft25 journaled within the cutter bar supporting member 19'an'dcoaxial with the axis of rotation of said cutter bar supporting member. A bevel gear 28 is keyed near the inner end of the shaft and meshes with a bevel pinion 30 on a shaft 32 extending longitudinally of the body portion 8 and coaxial with the pivotal axis of the cutter head 7 so the sprocket 24 may be driven from the shaft 32 in all positions of the cutter head 7 and cutter bar 8 with respect to the body portion 6. 1
The shaft 32 has a sleeve 33 thereon extending substantially the length of said shaft which is journaled in ball bearings generally indicated at 34 in the body portion 6 and cutter head 7. A shaft 35 is coaxial with the shaft 32 and abuts the rearward end of said shaft. The shaft 35 is journaled in ball hearings in the body portion 6 and is driven by the motor 23 through a motor pinion 36 and spur gear 37 keyed to said shaft. Suitable clutch means are provided to operatively connect the shaft 35 with the shaft 32. Said clutch means is herein shown as a jaw clutch and comprises a member 39 feathered on the shaft 35 having clutch jaws 40 thereon which may engage clutch jaws 41 on a member i2 keyed on the rearward end of the shaft 32. A suitable system of levers of the usual type (not shown) is provided to slide the member 39 along the shaft 35 to engage the clutch jaws i0 With the clutch jaws 41 to drive the shaft 32 from the shaft 35 and thus drive the cutter chain 9 about the cutter bar 8 in the guides 10 in all positions of the cutter head 7 and cutter bar 8 with respect to the body portion 60f the mining machine.
The driving connection from the motor 23 to the pinion 21 for rotating the gear segment 20 and cutter bar 8 about the axis of said gear segment includes a gear 45 which is driven by the gear 37 and which is keyed on a longitudinal shaft 45 journaled in the body portion 6. Bevel pinions .47 and 48 are freely mounted on the shaft 46 and mesh with opposite sides of a bevel gear 49 for driving said bevel gear in opposite directions when either of said bevel pinions are operatively oonnectedto the shaft 46. Jaw vciutch means are provided to driveeither of the bevel pinions 47 or 48 from the longitudinal shaft 46. Said jaw clutch means herein comprises a clutch collar 50 feathered on the shaft 46 having clutch jaws on each end thereof engageable with either clutch jaws 51 on' the bevel pinion 47 or clutch jaws 52 on the bevel pinion 48 so that either of said bevel pinions maybe driven from the shaft 46 to providea means for reversing the direction of rotation of 'the bevel gear 49. The clutch collar 50 is'moved'along' the shaft 45 by a suitable system of levers. of the ordinary type (not shown). The bevel gear 49 drives'a transverse shaft 58 having a worm 54 integral therewith. The worm 54 meshes with and drives a worm gear 55 keyed on a sleeve 56 freely mounted on a sleeve 57 which in turn is keyed to the longitudinal sleeve 33 on the longitudinal shaft 32. One side of the worm gear 55 bears against a collar 58 threaded on the sleeve 57 while the opposite side of said'worm gear bears against a flange 60 integral with the sleeve 56.
63 with the clutch jaws 61 so the sleeve 33 may be selectively driven from the worm gear 55.
A spur gear 65 is keyed on the forward end of the sleeve 33 and meshes with and drives a spur gear 66 on a longitudinal shaft 67 journaled in the cutter head 7. A worm 68 is provided on the forward end of the longitudinal shaft 67 and meshes with and drives a worm gear 69 on a transver e shaft 70. A pinion 71 is keyed to the shaft and meshes with and drives a spur gear 75 freely mounted on the transverse shaft 22. A clutch member 76 affords selective connection between the gear '75 and the shaft 22 as described. Rotation of the transverse shaft 22 rotates the pinion 21 and gear segment 20 about the axis of the cutter bar supporting member 19 to pivotally move the cutter bar 8 about the axis of said gear segment and the cutter bar supporting member 19. It will now be seen that the cutter bar 8 may be pivotally swung by power in any plane in which said cutter bar may be positioned, there being sufiicient clearance at the front end of said machine for said cutter bar to swing through an angle of approximately 180 degrees.
Thus, when the cutter head is rotated so the cutter bar is disposed in a substantially horizontal plane, either above or below the center of the axis of rotation of the cutter head (as shown by dotted lines in Figure 1) said cutter bar may be swung either to one side or the other of the machine so as to make an arcuate cut in advance of the machine, or if desired the cutter bar may be held in a fixed position to one side of the machine, and the entire machine be moved along the side of a Working face in a mine wall so as to make a slabbing cut therein. For this latter purpose the worm G8 and worm gear 69 are of the self locking type, that is to say, the pitch of said worm and worm gear is such as to lock the cutter arm in any position to which it may be moved; as, for instance, when the cutter is positioned for making a lateral or slabbing cut as above illustrated.
A spur gear 77 is loosely mounted on the transverse shaft 53 and has selective connection therewith through a clutch member 78. The clutch member 78 has a plurality of pins 79, 79, therein engageable with a plurality of apertures 80, 80, in the face of the spur gear 77. The ends of the pins 79 are beveled and the apertures 80 are correspondingly shaped so as to receive the beveled ends of said pins. The angles of incidence of the apertures 80, 80, are such that the clutch member 78 will be disengaged from the gear 77 upon overload of said gear. The spur gear 77 drives a spur gear 81 keyed on a shaft 82. A worm 83 is integral with said shaft anddrives a worm gear 84 keyed on a sleeve 85 coaxial with the longitudinal shaft 32. The sleeve 85 is feathered on a sleeve 36 which is slidably mounted on the sleeve 33 for rotatable movement thereon. I
A gear 87 is keyed on the sleeve 85 and is driven therefrom. Said gear serves as a sun gear of a planetary reduction gearing device and meshes 'with and drives planetary pinions 88 rotatably mounted on shafts 89 fixed in a cage 90 which is rotatable within a casing 91 for said planetary reduction gearing device. The casing 91 is keyed to the inner portion of the housing of the main body portion 6 and has an internal gear 92 on its inner periphery. The planetary pinions 88 mesh With said internal gear and rotate aboutsaid internal gear on rotation of the sun gear 87 and cause the cage to rotate therewith. Planetary vpinions 93 are freely mounted on. shafts 94 fixed on the cage 90 and are forwardly of the planetary pinions 88 so as. to mesh with a sun gear 95 keyed to the sleeve 85 and adjacent the forward portion of the sun gear 87 and an internal gear 96 on the inner periphery of a casing 97. The sun gear95 is of the same pitch and has the same number of teeth as the sun gear 87 so the planetary pinions 93 will drive the internal gear 96 on rotation ofthe sun gear 95 and the cage 90. A member 98 abuts the forward portion of the casing 97 and is fixed thereto so as to rotate therewith. The member 98 has a plurality of clutch jaws 99 depending from its inner periphery engageable with clutch jaws 100 on a collar 101 rotatable on the sleeve 86 and movable with said sleeve as said sleeve is moved longitudinally along the sleeve 33. The clutch jaws 100 are engageable with clutch jaws 102 depending from a member 103 keyed within the cutter head 7 for rotating said cutter head upon rotation of the internal gear 96.
The clutch jaws 100 are engaged with or disengaged from the clutch jaws 102 by longitudinal movementofthe sleeve 86. Clutch jaws 104 are provided on the forward portion of the sleeve 86 and are engageable with the clutch jaws 102 on 'the member 103 .for rotating the cutter head 7 at the speed of rotation of the worm gear 84. The sleeve 86 is moved reciprocably along the sleeve 33 to engage either the clutch jaws 100 or 104 with the clutch jaws 102 to rotate the cutter head 7 at either a fast or slow speed by means of a clutch collar 105 threaded on the rearward portion of the sleeve 86 and a suitable system of levers of the ordinary type (not shown). In order to lockthe cutter head 7 in any desired position of adjustment thereof either the clutch jaws 100 or 104 must engagewith the clutch jaws 102. The worm 83 and wormgear 84 are of the self locking type to prevent rotation of the cutter head 7 when the clutch member 78 is disconnected from the gear 77 and either the clutch jaws 100 or 104 are in engagement with the clutch jaws 102.
It may be here seen that the cutter bar 8 may be moved about thelongitudinal axis of the cutter head 7 at a relatively highrate of speed to quickly adjust said cutter bar to its various desired cutting positions as is illustrated in Figure 1 or at a slow or feeding speed when it is desired to make an arcuate cut in a mine wall as is fully described in my prior application, Serial Number 153,253, filed December 8, 1926.
ily be disassembled and which occupies a minimum amount of space both laterally and vertically.
, The cutting element 1 isvertically adjusted in the guide members 2 (See Figures 1 and 4) by means of vertically disposed shafts 107,107, on each side of the body portion 6 which are threaded through blocks 108, 108, held from vertical movement in guides 109, 109, integral with the body portion 6 of the cutting element 1. The
of said shafts has a worm gear keyed thereto. Worms 111, 111, on a transverse shaft 112 mesh with and drive said worm gears. The shaft 112 may be driven in opposite directions from a motor 113 on the rearward portion of the base frame 3 (see Figure 5) by means of a motor shaft 114, universal joint 115, connecting shaft 116, universal joint 117, shaft 118, bevel, gear 119, bevel gears 120, 120, and clutch members 121, 121. The bevel gears 120, 120, are driven in opposite directions by means of the bevel gear 119 and are selectively connectible with the shaft 112 to drive said shaft in opposite directions and thus raise or lower the cutting element 1 in the guide members 2, 2, by means of the clutch members 121, 121, which are connected together so one clutch member 121 is disengaged from its bevelgear 120 when the opposite clutch member 121 is engaged with its respective bevel gear 120. V
The continuous treads 4, 4 are driven from the motor 113 by means of a motor pinion 123 keyed on the motor shaft 114 which meshes ,100 with and drives spur gears 124, 124, freely mounted on shafts 125, 125, on each side of the motor shaft 114. The spur gears 124, 124, are selective- 1y connectible with the shafts 125, 125, by means of clutch members 126, 126. The clutch members 105 126 may be of any well known type but are herein shown as pin clutches, the angle of incidence of the pins and apertures into which said pins fit being such that said clutches will slip and disconnect the shafts 125, 125, from the spur 1 10 gears 124,v 124, upon overload of said shafts. Worms 127, 127, are integral with the shafts 125, and drive worm gears 128, 128, on transverse stub shafts 129, 129. A spur gear 130 is keyed to each stub shaft 129. The spur gears 130, 130, mesh with spur gears 131, 131, keyed on shafts 132, 132. Sprockets 133, 133, are keyed to said shafts and drive the continuous treads 4, 4. The continuous treads 4, 4, are threaded over the driving sprockets133, 133, on the rearward portion of the machine and sprockets 134, 134, keyed on shafts 135, 135, on the forward portion of the base frame 3 for driving said shafts. The clutch members 126, 126, are operable independently of each other by means of a suitable system of levers of the ordinary type so that both of -the continuous treads 4 may be driven simultaneously to drive the mining machine in a straight line or so that powermay be released from one or the other of said continuous treads to turn the mining machine in one direction or the other. Shafts 132, 132, and 135, 135, project beyond the sides of the base frame 3 so that track wheels 5, 5, may be inserted thereon if desired.
The:use and operation of the machine above described willnow be clear to one familiar with the art. The machine may be used for making an ordinary shearing .cut at either side of the machine or in making an overhead arching cut when advancing tunnels or main entries as is fully disclosed in my prior application, Serial Number 153,253, filed December 8, 1926. This cut consists of a shearing out from the floor at one side of the machine to a position substantially in the same horizontal plane as the axis of rotation of the cutter head. From this position the cutter bar is locked in a stationary position and the cutter head is rotated about an arc to a position on the opposite side of the machine from the initial shearing cut and a shearing cut is made from this position to the mine floor. This leaves a kerf in the form of an arc the core of which may be removed by the usual mining methods. The machine may also be used in over cutting or under cutting, or in making a slabbing out at various heights in a mine wall. These various cuts being produced either by maintaining the machine frame stationary and swinging the cutter bar about its axis, or by positioning the cutter bar in a fixed position and feeding said bar by advancing the machine bodily along the track or mine bottom or by a combination of each of these metl eds. The various feeding operations above described are well known to the art, vertical adjustment of the cutting element being obtained by vertically moving the cutting element 1 in its guide members 2, 2..
