- An indicator 188 of any well known character is also provided in order that variations in the width of the track may be observed and lateral adjustment of the dressing tools effected accordingly.
- either the grinding or the milling carriage is attached to the platform dependent upon the nature of the work to be performed. It will be seen that in either case owing to the universal coupling employed, a rising and falling or lateral movement of the main platform will not affect the rail dressing operations of the divided carriage as the machine travels over the rails. In addition when the machine is traveling idly, 2". 0., to or from its work the longitudinally divided carriage may be ele rated from the rails by means of the. cant: liver without disconnecting the said car riag'c. Still further owing to the carriage being divided and the sections centrally pivoted the differences in one rail of a track will not affect the dressing operations as regards the other rail, the movement of one section of the carriage being obviously independent of the other.
- the machine In operation, the machine must first be driven to the place where the rails require treatment. To drive the machine to the point where the rails are to be operated upon, the engine is started and the clutch on the engine shaft 11 is thrown into gear. This rotates the sprocket wheel 12, which by its chain rotates the sprocket wheel 13, on the shaft 1 .1. The sprocket wheel 15, which also rotates with this shaft, drives the sprocket wheel 16 on the shaft 17. The sprocket wheels 18 rotating with the shaft 17, new drive onto sprockets 19 of the rear axle 3, the front axle 5 being driven through the sprocket wheels 20 and 21. This conveys the machine to the position desired at a comparatively fast speed.
- the high speed gear is thrown out of ac tion by the clutch on the engine shaft 11.
- the carriage is now lowered onto the rails by the cantaliver 90. This is brought about by first throwing the required bevel wheel 5e, into gear with the pinion 49, causing rotation of the shaft 56, which by operating the clutch 85, turns the worm 86, which in turn rotates the worm wheel 87, thus turning the screw 88 and raising the inner end of the cantaliver.
- the carriage being now in position on the rails, the slow speed or working gear is brought into operation by throwing the clutch of the pulley 24;, into gear with the shaft 25.
- the drive is now from pulley 22, on the engine shaft, to the pulley 24-.
- the for ard driving friction cone 26 being thrown into gear with the disk 29, the worm 31 drives the worm wheel 32.
- the clutch 34 is now thrown into operation. causing the sprocket wheels 35 to rotate. These in turn drive the sprocket wheels 36 and the back axle 3, the front axle 5 being driven as before,'through thesprocket wheels 20 and 21.
- the machine is now traveling at its low working speed, the milling or grinding tools being driven from the pulleys 124 by the belts 125.
- the wheels and 7 4c are brought into operation.
- the wheels 65 and 74 are first lowered to the ground. This is effected by throwing the pulley 37 into gear with the belt on the pulley 22, of the engine shaft.
- the pulley 37 through the sprocket wheels 39 and 48 drives the bevel pinion L9.
- the bevel wheel 5 1T which drives in the direction required for lowering the cross over wheels, is thrown into gear with the bevel. pinion 49, and rotates the shaft 56.
- the clutches 57 and 66 are now thrown into operation.

Specification of Letters Patent.
Patented Feb. 13, 1917.
Application filed January 11, 1916. Serial No. 71,597.
To all whom it may concern Be it known that I, Josnrrr W'ILLIAM EUN- SON, a subject of the King of Great Britain and Ireland, and a resident of the city of Brunswick, a suburb of the city of Melbourno, in the county of Bourke. State of Victoria, Commonwealth of Australia, (whose post-office address is 302 Barkly street, East Brunswick,) have invented certain new and useful Improvements in Machines for Dressing Rails, of which the following is a specification.
This invention relates to machines adapted to treat railway and tramway rail lines for the purpose of removing deformities therein without removing the rails from the traclc As disclosed by the specification of prior U. S. A. Patent No. 1,032,721, dated the 16th day of July, 1912, the defects of both classes of rail lines after use include corrugated surfaces and uneven joints, both of which faults are commonly removed by a. grinding tool. In tramway lines the grooves require deepening and the rail lips require to be correspondingly reduced in height. These functions are performed by suitable tools. In practice the corrugations and joint imperfections are first removed after which any further defects are treated.
The object of this invention is to provide a machine by which rail. deformities may be readily and consistently eliminated or reduced from both rails of a track simultaneously, regardless of verti ad or lateral rail distortion and differences in the elevation of the rails. The invention differs essentially from the prior invention above referred to in that although it includes a framework or platform to which is pivotally connected a carriage, the carriage according to the present invention cannot be influenced by longitudinal movement of the platform, is not: swung by the platform on curves and is divided longitudinally into sections each of which carries. the necessary tool and adjusting mechanism for indepemlently treating the rail below it.
The chief novelty in the invention is thought to reside in the divided carriage and the adjustments connected therewith, in the manner of connecting the carriage to the platform, and in the manner of bodily raising the carriage clear from the track or lowering the said :arriage to the track without disconnection from the platform. The features of novelty. however. are pointed out in the appended claims.
Referring to the drawings which form a part of this specification:

The invention includes (Figs. 1 and 2) a pair of first driving track wheels 2 mounted upon a first axle 3 and a pair of second driving track wheels 41; mounted upon a second axle 5. The axles 3 and 5 are each supported .in bearings 6 above which are springs T. The bearings (3 and springs 7 are dis posed in guideways 8 formed in. a suitable platform or framework 9.
Disposed upon the platform 9 an ole-1- tric or other motor 10 l'iaving a shaft 11. Secured to one end of the shaft 11 is a sprocket wheel 12 driving by a suitable sprocket chain a sprocket wheel 13 mounted upon a shaft 14;. Secured to the shaft 1-1: a sprocket wheel 15 driving by a suitable sprocket chain a. sprocket wheel 16 mounted upon a. shaft 17. Secured to the shaft 17 is a pair of sprocket wheels ]8 driving by suitable sprocket chains a pair of sprocket wheels 19 secured to the first axle 3. Secured to the first axle 3 is a sprocket wheel 20 driving by a suitable sprocket chain a sprocket wheel. 21 secured to the second axle By means of the gearing described, which may be controlled by a suitable clutch (not shown) upon the engine shaft, the platform is driven at a comparatively fast rate of speed. The gearing de scribed is employed only when it is desired to drive the machine to and from its work, for example, but not during its working operations.
Secured upon the other end of the motor shaft 11 is a belt pulley '22 driving by a belt 23 av belt pulley Q-ilsecured to a. shaft 25. The pulley Q-l: is ('OI'llil'OllGd by a. suitable internal or other clutch. Mounted upon one end of the shaft 25 is a sleeve and on the latter is a pair of friction cones 2K3 controlled by opposite hand levers 28 in or der that either cone may be introduced into active operation from either side of the platform. Driven by either of the friction cones 26 is a friction disk 29 secured to a worm shaft 30 havin a worm 31. Engaged by the worm 31 is a worm wheel. 32 mounted upon a shaft 33. Secured to a sleeve y, loosely mounted on the shaft 33 is a pair of sprocket wheels 35 driving by suitable sprocket chains :1 pair of sprocli'et wheels 36 secured to the first axle 3. The mechanism for shifting clutch Elias shown in F 1 and 2, comprises a clutch member (a, splined on shaft 33, andv capable of being moved into and out of engagement with a clutch member 6, integral with the sleeve f]. A pivoted yoke c is suitably mounted adjacent the clutch member a, and to the upper end of the yoke is pivoted a link (Z, pivoted at its outer end to a hand lever e, pivoted on a bracket at 7'. By operating the hand lever, the yoke c is rocked, which in turn slides the clutch member into or out of engagement with the clutch member Z), depending, of course, in which direction the hand lever is operated. By means of the gearing described the machine is propelled slowly during working operations and may be reversed by reason of the friction cones 26 only one of which is engaged with the disk 29 at any one time.
Engaging the belt passing around the belt pulley 22 is a friction pulley 37. This (Figs. 9 and 10) is secured to a spindle 38 having secured at its one end a sprocket wheel 39. The spindle 38 is mounted in the arms d0 of the fork of a lever 11. Formed through the lever is a lateral nut hole. Loosely disposed in the nut hole is a nut 42. Formed through the lever 451 at right angles to the nut 4:2 is a. longitudinal hole in dicated at 4:3. The hole 43 is, as shown in Fig. 9, enlarged or hell mouthed from its center toward its ends. Integral with the lever i1 is a boss 41%. disposed in which is a bush 15. Formed through the bush is an eccentric hole. Disposed in the eccentric hole in the bush is a sleeve lG. Concentrically mounted in the sleeve is a spindle 47 having upon. one end a sprocket wheel e8. The sprocket wheel a8 is driven by a suit able sprocket chain from the sprocket wheel 39. Secured to the other end of the spindle i7 is a bevel pinion 49. Passing through the elongated hole 13 and the pivotal nut 42 is the threaded end of a hand wheel spindle 50 having a hand wheel 51. and a collar 52. The spindle 5O passes'through an enlarged or bell mouthed hole in a portion of the ilramework 9 the collar 52 freely bearii'ig against the said framework. llpstanding above the collar and carried by the platform or framework 9 of the machine a pulley rest 53. Upon rotation of the hand wheel 51, the nut l2 moves along the spindle 50. The boss of the lever 41 turns about the bush 45 which remains stationary. Inward movement of the lever 41 engages the pulley 37 with. the belt 23 passing around the belt pulley 22. The spindle 38 is thereby rotated and by the sprocket wheels 39 and 49 rotates the bevel pinion 49. By partially turning the bush 45 in any suitable \vay adjustment of the relative positions of the spindle 47 and the boss 44 of the lever 41 is effected thereby providing adjustment of the sprocket chain (not shown) between the sprocket wheels 39 and 4:8. The pulley rest 53 prevents any inadvertent rotation of the pulley 37 when out of action. This may occur should the belt 23 be slack. The rest 53 also acts as a brake when the machine is being side tracked or moved laterally upon a road having a high center or crown, as will be hereinafter more fully understood.
Engaging (Figs. 1 and 2) the bevel pinion 49 is a pair of bevel wheels o -l mounted on a single sleeve, and shifted together by a reversing lever 55. The sleeve carrying the bevel wheels is mounted upon a longitudinal shaft 56 and may by a suitable handle he slid on the same in order that one bevel. wheel only will be in engagement with the pinion 19 to drive shaft 56 in either forward or reverse direction, depending of course which of the beveled wheels 5% is .in engagement with said pin ion 19.
Disposed upon the shaft 56 is a clutch member 57 controlling a pair of sprocket wheels 58. The pair of sprocket wheels are mounted on a sleeve ai whichis loosely mounted on the shaft 56, and. at one end of this sleeve is formed the clutch member 57. Secured to shaft 56, adjacent the clutch member 57, is a clutch member 0". By operating a suitable hand lever clutch member 57 is moved into engagement with the clutch member 0*, with the result that motion of shaft 56 is transmitted to the sprockets 58. Each sprocket wheel 58 by a suitable sprocket chain rotates a sprocket wheel 59 mounted upon a shaft 60. Carried by each shaft 60 is a worm 61 engaging a worm wheel nut 62 through which passes the threaded shank 63 of a slide The slides 64: move in suitable slideways formed in the platform or framework 9. Mounted Upon a stud or axle projecting from or forming part of each slide (ll is a first cross-over wheel (37 Mounted upon the shaft 56 is a clutch (l6 controlling a pair of sprocket wheels ()7 each of which by a suitable s n'ocket chain drives a sprocket wheel (38 secured to a shaft 69. Carried by each shaft (39 is a worm engaging a worm wheel nut 71 through which passes the threaded shank 72 of a slide 73. Mounted upon a. stud or axle carried by or forming part of each slide 73 is a second cross over wheel 71.
The purpose of the cross over wheels and 74 is to move the machine laterally or from the track, when it is desired to place the machine on. the track preparatory to dressing the rails, or when it is desired toremove the machine from the tracks after the operation of dressing is completed.
Disposed in each of the cross over wheels 65 and 7a is (Fig. 7) an internally toothed ring 75. Engaging each internally toothed ring is a toothed wheel 76 mounted upon clutch 3.
a shaft 77. Secured to each shaft 77 is a toothed wheel 78 engaging a toothed wheel 79 mounted upon a shaft 80. Secured to each shaft 80 is a sprocket wheel 81.
Each sprocket wheel 81 (Fig. is driven by a suitable sprocket chain from a sprocket wheel 82. A pair of s n'ocket wheels 82 is provided for the first cross-over wheels 05, said wheels being mounted on a sleeve forming a part of the clutch, the sleeve being moved on the shaft by a suitable lever. A pair of sprocket wheels is also provided for the second cross-over wheels 71-. The sprocket wheels 82 are mounted upon a sleeve mounted on the shaft 56. The pair of sprocket wheels 82 relative to the first cross-over wheels (55 are controlled by a The pair of sprocket wheels 82 corresponding with the second cross-over wheels 7% are controlled by a clutch 81'.
Disposed upon the shaft 56 is (Figs. 1, i2, 3, 4, l1 and 12) a clutch 85 controlling a worm 86. The worm 80 engages a worm wheel 87 secured to which is the lower end of a screw 88. The upper end of the screw 88 passes through a nut 89 loosely mounted in free holes formed in the inner ends of the sides of a cantaliver 90. The cantaliver 90 is intermediately pivoted to a pivot pin 91 carried by a bracket or the like upstanding from the platform or framework 9. The outer end of the cantaliver 90 outstands from and overhangs the said platform or framework 9.
Carried by the outer end of the cantaliver 90 are (Figs. 3, 1. 11 and 12) right and left pivot pins Pivoted to each pivot pin is the upper end of a bifurcated link 93, the lower end of which is pivoted to a pivot pin 9.4.- carried by the fork 95 of a pivotal member having a shank 96. The shank 96 of each pivotal member loosely mounted in a lug 97. A lug 97 upstands from the right section 98 and from the left section 99 of a hmgitudinalty' divided carriage hereinafter more fully described.
Carried by the right section 98 of the divided carriage, at the inner or platform end thereof. is a bearing 100. Carried by the left section 99 of the divided carriage. at the inner or platform end thereof, is a bearing 101. Carried by the end of. the platform or framework 9 adjacent the right section of the divided carriage is a second bearing 102. Carried by the end of the platform or framework 9 adjacent the leftsection of the divided carriage is a second bearing 103. Loosely inonnted in each of the bearings is the shank 10%. of a pivotal member having a fork 105 carrying a pivot pin 106.
Pivoted (Figs. 4: and 12) to the pivot pin 106 relative to the bearings 100 and 103 and extending therebetween is a first diagonal link 107. Pivoted to the pivot pins 106 relative to the bearings 101 and 102 and eX- tending therebetween is a second diagonal link 108. The links 107 and 108 cross each other, each being provided at the point of intersection with a pin hole indicated at 109, to accommodate a locking pin 110. lVhen the machine is traveling but not operating upon a rail line the carriage is elevated from the rails and the locking pin 110 is placed in position and the links 107 and 108 do not move in relation to each other. The carriage cannot swing laterally when the machine is traveling fast. The pin 110 is always removed before the carriage is lowered to the rails to commence dressing operations. hen the machine is o :)c1'ating the pin 110 is always remiwed in order that the links 107 and 108 may vary their positions in relation to each other. By using the universal coupling described, the tendency, during dressing operations, of the platform, when rounding a sharp curve, to throw or deflect the carriage from its correct path or hard up against the rails is obviated.
Formed (Figs. and 6) in the inner or bearing surface 111 of the right section 98 of the longitudinally divided carriage are two opposite segmental guide grooves 112. Each groove is preferably provided with undercut sides as shown. Formed in the right section 98 is also a central hole indicated at 113. Protruding from the bearing surface 114i of the left section 99 of the longitudinally divided carriage are two opposite dove-tailed segmental guides 115 engaging the grooves 112. Projecting from the bearing surface 114 is also a boss or trunnion 116, engaging the central. hole 113.
The purpose of forming the carriage in two sections, and pivoting these sections together, is to permit of the treatment of one rail. of a track without its being affected by defects, such as elevations or depressions in the surface of the other rail. By this construction the vertical. movement of each section is independent of the other,thus permitting either section of the carriage following irregularities in the rail surface. regardless of the surface of the companion rail. If the surfaces of the two rails of a track are not in perfect horizontal alinement, the right hand rail being perfectly horizontal while the left hand rail has a tendency to dip, the right hand section of the carriage will remain horizontal, while the left hand section will tilt on the pivot 116, and keep in close contact with its rail. This construction insures the wheels adhering closely to the track and the tools down to the work.
Resting (Figs. 3, 4, 11 and 12) upon the rails to be dressed and supporting thereon the right and left sections 98 and 99 of the divided carriage are four series of rollers 117 A series of rollers is provided at each end of each section of the divided carriage, each section being thereby supported upon the rail beneath it by two series of rollers. Each series of rollers 117 is mounted in a roller frame or casing 118, the rollers being disposed in two rows forming an irregular or stepped line as shown in Fig. 4. Carrier by each frame 118 are removable side rollers 119 shown for convenience in Fig. 12 only. The side rollers are employed only in connection with plain headed or railway rails and are removed when grooved rails are being treated. Or the rollers 119 may be dispensed with and flanges be provided upon the frames 118. Formed in each roller frame 118 is a pin hole through which passes a pin 120 carried by the lower end of a vertical slide 121. Formed in each vertical slide 121 are adjusting slotways 122. Disposed in each of the slotways 122 is an adjusting bolt 123. By reason of the bolts 123 and slotways 122 the vertical slides 121 of each section of the divided carriage may be adjusted in relation thereto. This is necessary when fitting grinding wheels of different sizes and when the diameter of a wheel becomes reduced through wear as will be hereinafter more fully understood.
Mounted (Figs. 1 and 2) upon the shaft u 25 before described is a pair of third belt pulleys 12st, a pulley being provided for each section of the divided carriage. Passing around each pulley 124 is a belt 125.
Each belt 125 passes over a guide pulley 126, 1
the guide pulleys being mounted upon extensions of the pivot pin 91 of the cantaliver 90.
W hen it is necessary to grind rails a longitudinally divided carriage having a grinding wheel for each rail is employed. When a grinding carriage is in use each belt 125 passes (Figs. 3, a and 8) over a guide pulley 127 secured to a shaft 128. The shaft 128 of each section of the carriage is mounted in sliding bearings hereinafter referred to. Disposed below each pulley 127 and driven by the belt passing over the same is a belt pulley 129 secured to a tool spindle 130 upon which is mounted a suitable grinding wheel 131.
The shaft 128 and tool spindle 130 of each section of the divided carriage are mounted in a box lever 132. The box lever 132 of each section of the divided carriage is pivoted at its platform end to a pivot pin 133 extending across the said carriage section. Secured t0 the other end of each box lever 132 is a segmental rack 134: engaging which is a worm 135 secured to the lower end of a vertical shaft 136. Secured to the upper end of the shaft 136 of each section is a toothed wheel 137 engaging which is a toothed. pinion 138 controlled by a hand lever 139.
Enga ing the belt 125 of each carriage section is a tension pulley 11-0. The tension pulley of each carriage section is mounted upon a shaft 141 disposed in sliding beanings 112. Mounted in the bearings 142 of ich carriage section is the shaft 128 thereof, hereinbefore referred to. The bearings 1 .2 are adapted to more along slideways formed in the box levers 132. 'Carried by each bearing and depending into the slide way below the same a nut 112. Passing through each nut and disposed in the slideway corresponding thereto is a screw 1-13. Secured to each screw 113 is a sprocket wheel 11-1. Passing around the sprocket wheels 1H relative to each tension pulley 110 is a sprocket chain (not shown). By rotating one of the screws 143 the pulleys 127 and 110 corresponding thereto are moved in relation to their box lever 132, the tension of the belt driving the corresponding tool spindle 130 being thereby regulated. This is necessary when vertical adjustment of a grindingwheel 131 has been effected by the rim-responding worm 135 and box lever 132 thereof.
Carried by each section of the divided carriage is (Fig. 1) a bearing 116 having therein a hole indicated at 14.7. The hole in each bearing 14 6 is enlarged or bell mouthed from center toward its ends, as shown. Mounted in each bearing 116 is a shaft 14.8 having secured to its one end a hand wheel 119. ts other end is threaded as at 150. idount'ed (Figs. -1 and upon the threaded portion 150 of each shaft 1-1-8 is a nut 151, pivoted to which is the upper end of a connecting lever 152, the lower end of which is secured to a rocking shaft153. The rocking shaft 153 of each section of the divided carriage is mounted in the box lever 132 thereof. Secured to each rocking shaft 153 are the upper ends of a pair of thrust levers 15% each having forni'ed in its lower end a trunnion hole. Engaging the trunnion holes of the thrust levers 151 are the trunnions 155 of a collar 156 engaging the tool spindle 136. The collar 156 may be retained-between nuts, collars, or the like of the spindle 130 in order that the said collar 156 cannot move along the said spindle, 130. By operation of the hand wheel 119 of either section of the divided carriage the tool spindle 130 thereof and the grinding wheel 131 mounted upon the said spindle are adjusted laterally in relation to the said section.
When a milling tool is provided for each section of the divided carriage the adj ustments and drives of the tools are modified as shown in Figs. 11 and 12. Each roller frame 118 then has mounted in the hole hereof a loose nut 157 through which passes a lateral threaded shaft 158. Each shaft .156 is mounted in suitable bearings carried by the lower end of the corresponding vertical slide 121. Secured to the outer end of each shaft 158 is a bevel wheel 159. Engaging each bevel wheel 159 is a bevel wheel 161) secured to the lower end of a vertical shaft 161. Secured to each vertical shaft 161 is av bevel wheel 162. A vertical shaft 161 is disposed near each end of each section of the divided carriage as shown. Engaging the bevel wheels 162 of each said section are bevel wheels 163 mounted upon a longitudinal shaft 161 extending between the vertical shafts 161. Secured to one of the vertical shafts 161 or an extension thereof is a hand wheel 165. By operation of the hand wheel 165 of either section of the divided carriage the two series of rollers supporting the said section are adjusted laterally in relation thereto, the nuts 157 mov- 1ng along the threaded shafts 158 and carrying the roller frames 118 with them.
Upstanding from each vertical slide 121 is a threaded extension 166. Each extension 166 passes through a worm wheel nut 167 engaged by a worm 168. Extending between the worm wheel nuts 167 of each section ofthe divided carriage and carrying the worms 168 engaging the said nuts is a longitudinal worm shaft 169 having secured to one of its ends a hand wheel 170. By operation of either hand wheel 170 the corresponding carriage section is vertically adjusted in relation to the series of rollers supporting it and the milling tool hereinafter referred to is consequently adjusted in relation to therail beneath it.
Projecting from each section of the divided carriage when a milling tool ,is employed (and if necessary also when a grinding tool is employed) are two studs 171. Secured to the studs of each section are the upper ends of inclined supporting arms 17 2 the lower ends of which are united to a tool spindle bearing 173. Mounted in the bearing 173 of each carriage section is a tool spindle 17 1 having mounted thereon a cutter disk 175 provided with a series of suitable cutters 176.
Each cutter disk 175 is rotated by a toothed wheel 177 secured to the cutter spindle. 17 1 of the said disk. Each toothed wheel 177 and cutter disk are capable of lateral movement in relation to the carriage section in which they are mounted. Lateral adjustment is effected in the same manner as that described in connection with the grinding tool adjustment hereinbefore describedf Engaging the toothed wheel 177 is a toothed wheel 178. The width of the wheel 178 is extended in order that the toothed wheel 177 when moved laterally will still remain in engagement. Or each spindle 174 may be adapted to slide through the wheel 177 thereon the said wheel not then being laterally adjustable. Each toothed wheel 178 is secured to a shaft 179 mounted in the corresponding section of the divided carriage. Secured to the shaft 179 of each section of the carriage is a worm wheel 180. Engaging each worm wheel 180 is a worm 181 secured to the lower end of a worm shaft 182. Secured to the upper end of the worm shaft 182 of each carriage section is a bevel. wheel .83 engaging which is a bevel wheel iSet. llach bevel wheel 18'!- is mounted upon a clutch shaft 185 controlled by a suitable clutch (not shown). Mounted upon each clutch shaft 185 is a belt pulley 186. The belt pulley 186 of each" carriage section is rotated l :1 corresponding belt from the shaft 27 of the platform S).
An indicator 187 of any well, known character is provided with each of the carriages described in order that the depth of the cut of the dressing tool may be regulated. An indicator 188 of any well known character is also provided in order that variations in the width of the track may be observed and lateral adjustment of the dressing tools effected accordingly.
With this invention. either the grinding or the milling carriage is attached to the platform dependent upon the nature of the work to be performed. It will be seen that in either case owing to the universal coupling employed, a rising and falling or lateral movement of the main platform will not affect the rail dressing operations of the divided carriage as the machine travels over the rails. In addition when the machine is traveling idly, 2". 0., to or from its work the longitudinally divided carriage may be ele rated from the rails by means of the. cant: liver without disconnecting the said car riag'c. Still further owing to the carriage being divided and the sections centrally pivoted the differences in one rail of a track will not affect the dressing operations as regards the other rail, the movement of one section of the carriage being obviously independent of the other. Owing to the multiple rollers employed at each side of the dressing tool of each section of the divided carriage irregularities of the rail surfaces do not affect the dressing of a rail as the rollers ride upon the crown of the corrugations or irregularities in a manner similar to that pertaining in the prior U. S. A. patent before mentioned. Either section of the divided carriage is adjustable independentlv of its fellow by the means already described. Still further in milling rails it is sometimes desired when a rail is loose, for example. and tends to vibrate or chatter to increase the liressure or weight upon the. said rail. This may obviously be effected by operation of the cantaliver which when depressed at its outer end will by reason of the links between it and the carriage sections cause pressure to be exerted upon the said. carriage. Should any great pressure b exerted it may be necessary to load the main platform with pig iron or in any other suitable way.
In operation, the machine must first be driven to the place where the rails require treatment. To drive the machine to the point where the rails are to be operated upon, the engine is started and the clutch on the engine shaft 11 is thrown into gear. This rotates the sprocket wheel 12, which by its chain rotates the sprocket wheel 13, on the shaft 1 .1. The sprocket wheel 15, which also rotates with this shaft, drives the sprocket wheel 16 on the shaft 17. The sprocket wheels 18 rotating with the shaft 17, new drive onto sprockets 19 of the rear axle 3, the front axle 5 being driven through the sprocket wheels 20 and 21. This conveys the machine to the position desired at a comparatively fast speed.
To commence operations upon the rails the high speed gear is thrown out of ac tion by the clutch on the engine shaft 11. The carriage is now lowered onto the rails by the cantaliver 90. This is brought about by first throwing the required bevel wheel 5e, into gear with the pinion 49, causing rotation of the shaft 56, which by operating the clutch 85, turns the worm 86, which in turn rotates the worm wheel 87, thus turning the screw 88 and raising the inner end of the cantaliver. The carriage being now in position on the rails, the slow speed or working gear is brought into operation by throwing the clutch of the pulley 24;, into gear with the shaft 25. The drive is now from pulley 22, on the engine shaft, to the pulley 24-. The for ard driving friction cone 26 being thrown into gear with the disk 29, the worm 31 drives the worm wheel 32. The clutch 34; is now thrown into operation. causing the sprocket wheels 35 to rotate. These in turn drive the sprocket wheels 36 and the back axle 3, the front axle 5 being driven as before,'through thesprocket wheels 20 and 21. The machine is now traveling at its low working speed, the milling or grinding tools being driven from the pulleys 124 by the belts 125.
When it is desired to move the machine laterally from the rails to allow train to pass. the wheels and 7 4c are brought into operation. The wheels 65 and 74 are first lowered to the ground. This is effected by throwing the pulley 37 into gear with the belt on the pulley 22, of the engine shaft. The pulley 37 through the sprocket wheels 39 and 48 drives the bevel pinion L9. The bevel wheel 5 1T, which drives in the direction required for lowering the cross over wheels, is thrown into gear with the bevel. pinion 49, and rotates the shaft 56. The clutches 57 and 66 are now thrown into operation. These through the sprocket wheels too 58 and 67, drive the sprockets 59 and 68, which through the worms 61 and 70, turn the worm wheelsGQ and 71, and lower the spindles 63 and '72, bringing the cross over wheels to the ground. This mechanism continues to operate until the track wheels 2 and 4;, are raised clear of the rails. The clutches 5'7 and 66 are 110w thrown out of gear with the shaft 56, and the clutches 83 and 84:, are brought into gear. By ,the sprocket wheels 81-82, and gearing 7 9-7 8, the cross over wheels are rotated in the de sired direction and the machine is moved laterally from the track.
To return the machine to the track the opposite bevel wheel 54 is thrown into gear with the bevel pinion 49. This rotates the shaft 56, and the cross over wheels in the opposite direction and moves the machine back to the rails. The clutches 83S l are then again thrown out of gear and the clutches 5766, thrown into gear with the shaft 56. As the shaft 56 is now rotating in the opposite direction to that before described, the sprocket wheels 5S-59, and (ST GS, will now cause the cross over wheels to be raised and the track wheels lowered onto the rails.
