Specification of Letters Patent.

Patented May 21, 1912.

' Original application filed January 17, 1910, Serial No. 538,519. Divided and this application filed February 4, 1911. Serial No. 606,499.

To all whom it may concern:

Be it known that we, MICHAEL Woons, a-

tralia, and THOMAS JEFFERSON GILBERT, a

subject of the King of Great Britain and Ireland, and residing at 1 Minnie street, Brunswick, in the countyof 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 dressing means are carried by an attachment which is pivotally secured to the machine as described, for example, in the specification to our copending application Serial No. 538519 filed January 17th 1910. The-object of the present invention is to provide an efiicient and readily attachable combined carriage and holder for a tool or tools adapted for use in removing the burs and bevels which occur at the bends or curves in a track having plain headed rails, and also to cut out new and true beds in the rails to permit'of the renewal of the fish plates.

The invention consists m a combined carriage and tool holder for use with rail dressing machines adapted to support vertical millin means and to be removably pivoted to t e machine about a central longitudinal axis thereof,

One mode of carrylng out the invention the accompanying drawings Figure 1 is an elevation of a combined carriage. andholder constructed in accordance with the present invention, and Fig. 2 is a plan view of the same. Fig. 3 is an end elevation of Fig. 1. Fig. 1 is a sectional.

elevation of a detail.

In all the figures parts have been omitted sectioned or broken away, for the sake of clearness.

In carrying out the invention according to one mode, the combined'carria-ge and holder consisting of a framework (1V is provided with removable trunnion caps b for accommodating hollow trunnions on the rail dressing machine, thus permitting of the carriagebeing removed when necessary. The framework a is supported on both sides by flanged wheels 0 each of which is mounted on a pin a? secured to or formed integral with a slide e attached to a screw f engaging with a worm wheel nut g which can be rotated by means of a worm h operated by ahand wheel 2' so that, on turning the hand wheel i the flanged wheel is raised or lowered. A removable adjusting piece j may be interposed between the framework a and the slide e for regulating the distance between the wheels so as to suit any gage of I rails.

Secured to the framework is an upper cross bar 70 and a lower cross bar Z upon which is supported at either end a laterally adjustable bracket m through which passes a vertical spindle ncarrying at its lower end a milling tool 0 which receives its motion from any suitable motor carried by the rail dressing machine, the arrangement of the gearing being as follows :The shaft 1 which passes through the hollow trunnions' of the raildressing machine, is connected at one end to a motor driven shaft by any suitable coupling, and carries at its other end a bevel wheel 9 engaging with one of two bevel wheels 17 slidably mounted on a shaft 8 upon each end of which is a toothed pinion t engaging with a toothed wheel 24 carried by a shaft '1) which is journaled in.

a bearing v, extending from the bracket m and carrles a bevel wheel w engaging with a bevel wheel 00 mounted on the spindle n. The bevel wheels 1" are engaged or disengaged with the bevel wheel 9 in any ordinary way, thus affording a convenient means of reversing the direction of rotation of the cutter.

In order to provide means for adjusting the milling tools in a, vertical direction, each spindle a (see Fig. 4) is provided at- The spindle n is provided with a screw thread y engaging with a toothed wheel nut 2 which engages with a toothed pinion 1 carried on a spindle 2 operated by a hand wheel 8. On turning the hand wheel 3 the spindle 12, is raised or lowered thus adjusting the tool.

Each bracket m is adapted to slide laterally upon the cross bars 76 and Z and is se cured thereto by means of flanges 4 and bolts 9, the necessary adjustment being effected by means of a hand wheel 5 operating a screw 6 which turns within a nut 7 in the framework 44 and moves the bracket m by means of a collar 8 the shaft 7; being adapted to slide through the wheel at so as to keep the bevel wheels to and as always in mesh.

lVhen burs and bevels are being treated in plain headed rails alining and steadying devices are used. This consists of a bracket 17 attached to the framework a and carrying a roller 11 which makes contact with the inner side of the rail head. Pivoted at 12 is a bell crank lever having a long spring arm 13 and a short arm 14;, the former of which can be adjusted by means of a screw 15, while the latter carries a roller 16 which, by means of the adjusting screw can be brought into contact with the outer side of the rail head.

The tools may treat either side of their respective rails to remodel the head thereof, or by using suitable tools new fish plate beds may be cut out accurately and speedily.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is 1. In rail dressing machines, a combined carriage and holder, means for removably and freely pivoting said combined carriage and holder to the machine about a central longitudinal axis thereof, cross bars carried by said combined carriage and holder, brackets supported by said cross bars, a vertical shaft supported by each bracket, a ver tical milling tool carried by each shaft, and means for laterally adjusting each bracket upon the cross bars.
