MACHINE FOR DRESSING RAILS.

To all whom it may concern;

Be it known that we, MICHAEL VVooDs, a subject of the King of Great Britain and Ireland, and residing at 309 Pigdon street, Princes Hill, Carlton, in the county of Bourke, State of Victoria, Commonwealth of Australia, and THOMAS JEFFERSON GLL- BERT, a subject of the King of Great Britain and Ireland, and residing at 1 Minnie street, Brunswick, in the county of Bourke, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in and Relating to Machines for Dressing Rails, of which the following is a specification.

This invention relates to machines for dressing rails of the kind in which the dress ing means are carried by an attachment which is pivotally secured to the machine as described, for example, in the specification to our co-pending application Serial No. 538519.

The object of the present invention is to provide an eflicient and readily attachable combined carriage and holder for grinding means adapted for use in removing corrugations and to lengthen short joint depressions.

One mode of carrying out the invention is illustrated by the accompanying drawings in which- A Figure 1 is an elevation of a combined carriage and holder constructed in accordance with the present invention. For clearness, parts have been sectioned, omitted or broken away. Fig. 2 is a plan of Fig. 1. For clearness parts have been sectioned, omitted or broken away. In this connection, portion of a grinding wheel guard has been removed, portion of one grinding wheel broken away and part of the worm gear for raising and lowering the said wheel removed. Fig. 3 is an end elevation of Fig. 2, looking in the direction of a single arrow. An outer eccentric cylindrical bearing, its toothed ring and the pinion turning it, at the right hand side, have been removed. Fig. i is an end elevation of Fig. 2 looking in the direction of the pair of arrows. One

grinding wheel and its dresser are removed, and a friction pinion at the opposite side is seen by the omission of an eccentric cylindrical bearing.

In carrying out the invention according to one mode, the combined carriage and Specification of Letters Patent.

Application filed February 4, 1911.

Patented July 16, 1912. Serial No. 606,498.

holder consisting of a framework a is provided with holes for accommodating the hollow trunnions on the platform of the raildressing machine, which holes are covered by removable trunnion caps j, to allow'of the combined carriage and holder being removed when necessary. The framework a is supported on one side by a flanged wheel I) mounted upon a pin 0 which is secured to or formed integral with a slide (Z which can be adjusted in a vertical direction by means of a screw 6 upon which is a worm wheel f engaging with a worm 9 upon a shaft h which can be operated by means of a hand-wheel z. The other side of the framework a is supported upon a series of rollers 79 mounted upon axles Z turning within a carrier m which is formed in two parts joined together and is provided with a hole through which passes the outer end of a pin 01., the inner end 0 of which is secured to the frame work. The carrier m is provided with inner and outer lugs p and Q having pins upon which are mounted side rollers r and s, the outer rollers a being beveled so as to clear upstanding fishplates. When grooved rails are to be operated upon, these side rollers are removed.

Mounted behind the rollers are the grinding wheels 6 and at which are driven, by any suitable motor carried by the rail dressing machine, the arrangement of the gearing for transmitting the drive being as follows The shaft c, which passes through the hollow trunnions of the machine, is connected at one end to a motor-driven shaft by a suitable coupling, and is provided at its other end with a bevel wheel to engaging with a bevel wheel :22 mounted upon a shaft 3/ which carries a toothed wheel 2 which engages with a toothed wheel 1 mounted upon a shaft 2. These toothed wheels are interchangeable with reserve wheels carried by the machine, so that a uniform peripheral speed may always be maintained for the grinding wheels. The shaft 2 carries a frlction wheel 3 engaging with friction wheelst mounted upon shafts 5 to each of which 1s secured one end of a suitable universal coupling 7 the other end of which is connected to a grinding wheel shaft 8 rotating within a bearing 9.

In order to start or stop either of the grinding wheels each friction wheel 4 is mounted eccentrically within a cylindrical hearing 6 to the ends of which are secured toothed wheels 10 which engage with toothed pinions 11 mounted upon a shaft 12 which also carries a spiral pinion 13 engaging with another spiral pinion 14 upon an;

inclined shaft 15. The shaft 15 carries at its'upper end a vbevel wheel 16 engaging;

with a bevel wheel 17 carried on a shaft 18, which can be operated by means of a hand wheel 19, which, on being turned, gives a partial rotation to the cylindrical bearing '6 thus moving the shaft 5 carrying the friction wheel a toward or away from the frict-ion wheel 3. Each bearing 6 is provided worm 2i engaging with a worm wheel nut 25. Each wheel 25 rests upon a collar 27 pivoted 1n bearings on the framework and forms a nut around the screw 28 which is pivoted to lugs 29 of the'b'earing 9 from the inner end of which extend links 21 pivoted 'to the framework by means of a pin 30. On

turningthe hand wheel 22 the worm wheel nut 251s caused to ro-tate,'thus raising or lower ng the screw 28 and consequently the grinding wheel shaft.

hen the rails of a track-do not correspond in lateral elevation,that is, when one is higher-than the-other, it is obviousthat independently of the position of the machine, the combined carriage and holder, upon reaching such a part of the track, will V turn slightly upon the trunnion's, thus per- "independently of those in the other rail.

mitting deformities in one rail being treated In order to bring the grinding wheels into the same lateral plane as the surface of the rail which is being treated, the flanged wheel 6 is adjusted by means of the hand wheel 2' in the manner hereinbefore described.

Any lateral adjustment of the grinding wheels which may be-required can be effectedby means of a hand wheel 32 operating a screw 81 which engages with a screw thread provided in the outer end of the pin n.

' The screw 31 passes through abridge 3 1 and is prevented fronimovi-ng axially with rela- 'tion thereto by means of collars '33. On turning the hand wheel 82 the combined carriage and holder is moved toward or away fronithe carrier m,-the lateral play of the wheel Z) on the pin 0 permitting of this.

The grinding wheels are provided with a guard 35 secured to the framework and having a hole through its crown above each grinding wheel. Arranged above each hole is a bridge 36 having its legs attachedtothe guard and serving as a guide for a slide 37 connected to a screw 38 operated by means of .a hand wheel and nut 39. At the lower end'of the slide 37 is a dresser 4'0 mounted upon a pin 11 carried by the slide, so that, on turning the hand wheel and nut 39 the dresser 4:0 is depressed into contact with the grinding wheel.

By using a series of rollers as hereinbefore described and-which form the subject matter of aseparate application filed by us March 11, 1911 and serially numbered 613,790 the grinding wheels are prevented from following the surface of the rail as the rollers ride upon the tops of the corrugations of the rail and thereby permit the grinding wheels to work at a regular depth.
