RAIL MILLING AND Application filed Kay 20,

To all whom il -may concern:

Be it known that we, MICHAEL Woons and THOMAS J EFFERSON. GILBERT, subjects of the King of Great Britain and Ireland, residing at 3.09 Pigdon street, Princess Hill, Carlton, and of 1 Minnie street, Brunswick, respectively, both in the county of Bourke, State of Victoria, Commonwealth of Australia, have invented a certain new and useful Ini noved Rail Milling and Dressing Machine, 0 which the following is o sPecification.

Our invention rerates to improvements in portable milling1 and dressing machines, for plain or roove rails, which are adapted to resha. e the said rails to conform to a suitable mod rail, without removal from their position in the track, 2'. e. in aim.

"The heads of both plain and grooved mils, even on installation, are often uneven at the joints and in a short time the original unevenness becomes accentuated by the formu tion of additional undulations. Moreover the heads of the plain or ordinary roll, especially on the sharp curves, are gou ed by the wheel-fie es, to such an extent tlint lips or ridges are ormed immediatel below the line of contact of the head with t e wheel-flange and with the result that derailment is frequent. ridges form in the Yes of street railway rails and; in addition, the

wearing down of the heads renders the grooves shallow, with the result that their function is radually destroyed.

bur machines consist essentially of a manun-lor power-propelled and dressing mechanism adapted to travel u on three or four wheels, as me be require and car-- pable of being convenientl transferred from one track to another. Suitable vertical andlateral tdjus'tingmenns are provided, which permit of the complete reversal of the-machineand of adjusting the height of the rear end of the machine, aswell as the lateral movement of the niuchine platform and the cutting tool. f

The front wheels F are elevated or depressed by worm wheels H, arranged to engage a worm H mounted on a shaft II and adapted to be rotated by a handle H. One of the front wheels F, is rovided with a toothed ring J, which is revo ved by alpinion K, when the handle L is rotated. 1e shaft upon which said pinion is mounted, may be extended and provided with a second pinion capable of engagin a toothed ring provided on the rear wheel To move the machine from track to track, cross-over rails are placed underneath the wheels F and over the tracks. The hand wheel G and the handle H are then rotated, forcing the wheels F downwardly upon the crossover rails and lifti the latform A upwardly. The rear trave ing w ieel B, can be elevated or de ressed in relation to the frame by a hand w eel B. Said wheel B has (see Fi 9) an internal flange and an external flange RV, being thereby applicable to both railway and street railwav rails. The external flange W is removed when street railway rails are being treated or when the machine is being propelled distances over railroad rails. hear the rear end of the machine, and underneath it, is (Figs. 1, 2 and 3) a vertical feed wheel M mounted it on one end of an axle N (Figs. 2 and 4). A ove said axle is a vertically movable stem O,adapted to elevate or depress the rear of the latform A, when the hand-wheel P is rotate as hereinrapidly propelled after described.

The machine can be backward and forward lay any form of motor as follows :-On the en of the first motion or motor shaft R is positioned (Figs. 1 and 2) a worm S, which drlves a worm wheel T and rotates an inclined shaft U. On the bottom of the inclined shaft is (Fig. 7) a bevel wheel V. Below the bevel wheel V are two bevel wheels W (see F 7). These are united by a sleeve piece X ranch has a groove to receive the fork Y of a lever B. The said bevel wheels W and sleeve piece X are ca able of alongitudinal movement upon an an e Z having a key A thereon. They are moved backward and forward by the lever B which is attached to a shaft C operated by a hand lever D.

The machine is pro lled by hand as follows :Above the plat orm (Figs. 1 and 2) is a traveling hand wheel E which rotates a shaft F having thereon an auxiliary turning wheel Y. At the lower end of the shaft is a worm G eng g with a worm wheel J secured (Fig. 7) to the axle Z. The said worm G is secured to the shaft in any well known way and may be released and Jushed up the shaft F toward the hand w reel E and out of gear with the worm wheel. Or the machine is slowly propelled (Fig. I) by a cone pulley I mounted on a second shaft 0 (hereinafter described) and a belt drives a cone pulley Q mounted upon the third shaft R A worm 5 drives a worm Wheel T loosely mounted .u )on the shaft F and capable of being secure to the shaft by a clutc i U 2 operated by 'a lever V.

A rotary cutting tool K, of any desired shape, is mounted upon a spindle X, bein" operated, as follows-.The motor shaft Ii drives a toothed wheel L, coacting with an idle wheel M, which in turn, is in mesh with, and adapted to operate, a toothed wheel N, mounted upon the shaft 0. Or the shaft R may be direetl connected with the second motion shaft The shaft O consists of two parts, united b a friction clutch P, operatively connecte by a sleeve Q, with a lever R. The lever is pivotally connected with a bracket S and intermediate the ends of said lever a clutch rod T is secured, the same being threaded at its outer end to receive a hand wheel U. Mounted u on the outer end of the second motion siait O (F s. 1 and 2) is a bevel wheel V in mesh wit a bevel wheel ll" upon the to of a cutting s indle X. The top end of t e cutting s in e K (Fig. 2) is supported by a screw 1 which does not rot-ate with the said spindle but is turned b a turn handle Z, and locked by a lockingl andle A.

The cutting too K may be fluted, and may either deepen the groove in a street railway rail and cut ofi any upstanding or outstanding lip, in the one operation, or perform these operations sin ly. On rails it may remove 51c outstanding lip and also reform the corner of the rail, in the one operation or separatel The machine is adyusted (Figs. 1 and 7) laterally (when grooved rails are be' treat ed), near the cuttin tool K as f0 ows:-- The traveling wheel T3 is loose on the axle Z and moves longitudinally thereon. Attached to the outer end of the axle Z is the inner end of an ad'usting thread B and on the outer end of this is a nut rotated by a hand wheel C which nut turns within a suitable collar 2 prot-rudin from the wheel B. Outside the hand whee C is a locking nut E. As the hand wheel C is rotated the wheclB moves longitudinall upon the axle Z.

When plain headed rails are being reformed flan ed or unflanged stopped or unstepped, rollers F are placed (Fig. 10) each side of the rail or the web, said rollers bein ada ted to turn in forks G. The shanks I of t e forks are threaded and around the shanks are nuts J, adapted to be turned b hand wheels K (see Fig. 2), within suitab e plain headed collars L Locking nuts M lock the hand wheels to the shanks and jam screws N lock the nuts M to the collars l wheels K are turned, the rollers F are moved to or from the rails. as O, sup Ol'illl the collars L, is attached to the plat orm If desired a air of these rollers may be placed each side 0 the cutting tool.

Adjacent to the deformed rail, is placed (Figs. 3, 4, 5 and 6) a model rail W, of any section. The top of the model rail may be flat, or elevated, depressed or hollowed in the center, the amount of elevation or depression depending upon the circumstances. Each end of this rail W is retained within a fork above a chair X, which chair rests upon sleepers Y and between each chair I)? and the model rail ll is (Fig. 3) an ad usting screw Z, the lower end of which is threaded into the chair. The screw Z is turned by means of tm'ning-holes A In each end of the model rail is a hole into which passes the outer end of a threaded rod B, provided with a turning collar B. The inner end of the rod 13 is threaded into a clamp which is locked to the rail by a screw D. By means of the adjusting screws Z and the threaded rods B the said model rail W is adjusted, as regards itslheight and distance, from the adjoining rai Rail heads are ground by a grinding wheel as follows :On the first motion shaft R is (Figs. 1 and 2) a pulley E". This, throl h the agency of a belt, drives a pulley F e pulley F tiu'ns a spindle G which is adapted to move longitudinally, said motion being effected (see also Fig. 1') bv a fork J on a lever H, the legs of which fork pass over a recess in the spindle G The lever may engage with a toothed rack K and is preferably intermediate]; pivoted, being provided at its ulpper end with a handle L. Attached to t e spindle G and above the rail to be treated, is a grin wheel M, composed of any desired materia s and having acutting edge of any section, said grinding wheel bein adapted to be lifted from the rail by the hand wheel P which elevates the platform. To the front traveling wheel B hereinbefore described is attached (Fig. 7) a toothed ring Z and this engages with a toothed rack A the lower flange B of which is secured to the rail flan e.

ll on on railway tracks it is desired to turn the machine end for end (Figs. 1 and 8) the hand wheel N of a turntable gear is rotated thereby turning the bevel pinion 0 and the bevel wheel P The bevel wheel P is secured to the top of a lifting screw Q the top of which asses through a hole in the platform A. eneath the platform and upon the raising screw is a collar R". The screw below the cellar R turns in a socket S As the hand I A bracket, such having a bottom fian e T, and embracing the socket is a guide I l secured underneath tin platform by a flange V.

We do not wish to be understood as limitiug ourselves to the exact details of construction and arrangement described, since various sli 'ht. and immaterial modifications may be made therein without departing from the spirit and the scope of our invention.

Our invention is operated as follower- Vl'hen it is desired to propel the machine rapidly, either backward or forward by power (Figs. 2 and 7) the hand lever D is pulled either backward or forward respectively. This moves the sleeve K (Fig. 7) upon the axle Z and thereby causes one of the bevel wheels \"l' to engage with the bevel Wheel V. The said bevel wheel V is driven by the inclined shaft U which is driven (Figs. 1 and 2) by the worm wheel T. The worm wheel T is driven by the worm S ositioned upon the first motion shaft R. l hen it is desired to pro e] the machine moderately fast b power 'g. 1), the hand Wheel U is turn throwing the friction clutch P into gear. A belt between the cone pulle s P and q: drives (see also Fig. 2) the third motion s aft R, which drives the worm S o erated by the clutch U upon the shaft As theshaft F rotates, it turns the worm G and e ages (see also Fig. 7) with the worm wheel 1 secured to the axle Z. When it is desired to propel the machine by hand, (Figs. 1 and 2) t e traveling hand wheel E is rotated, thereby rotating the shaft F and the worm wheel J. When it is desired to move the front end of the platform laterally over grooved rails, (Figs. 1 and 7) the hand wheel C is turned, whereby the axle Z is projected into or out of the traveling wheel B. In addition to the movement of the front end of the platform over grooved rails, it is often necessary to accomplish the movement of the machine laterally over plain headed rails and when the machine is to be adjusted latorally over plain headed rails, the hand wheels K (Fig. 10) are rotated in order to move the glililtform transversely as regards the red. on a defective joint, such as seen in Fig. 6, requires reforming, a model rail W is placed adjacent to the deformed one. It is evident that the model rail W ma} be placed adjacent such a. rail as shown in lg. 10, or that shown in Fig. 5, but it is obvious that the deformity in the rail shown in Fig. 10 must be distant from the forks G in order to permit of the model rail being placed adjacent to said deformity, and it IS obvious that said forks G do not necessarily necessitate the exclusion of the model rail in those instances when it is desired to clamp the machine to the rail as shown in Fig. 10. The top of the modal rail is of such 0. formation that the defect in the deformed rail will he as much elongated as possible. The chairs X upon which it rests are placed upon sleepers Y. Then adjusting screws 7 are turned (Fig. 3) and the said model rail is elevated (and platform A if necessar Or the back end of the platform can be e evated by turning: the wheel on to a cross-over rail placed beneath it. The platform can then be lowered on to the model wheel and rail. The hand wheel P is then turned (Figs. 1 and 2) and the model rail wheel Q descends on to the model rail W and su ports the platform A. The grinding wheel ii is then vertically adjusted to the deformed rail and the platform A is moved backward or forward by hand or by power. 'hen grooved rails require lips in the grooves removed or the said grooves deepened, the cutti v spindle X may be supplied at its lower on with a suitable cutting tool K for either removing the lip or deepening the groove, or both.
