This invention relates to new and useful improvements in milling and cutting devlces particularly adapted for use in conjunctionwith work on railway tracks.
An important object of the invention is to provide a device of the stated character .which is relatively light in weight and permlts the easy manipulation thereof by the operator.
Another object of the invention is to pro 1g vide a device of the stated character having a novel drive mechanism intermediate a source of ower and the cutting tool.
other object of the invention is to provide a machine of the stated character having novel means for guiding the cutting and milling of a rail to correspond to the external contour thereof.
Another object of the invention is to provide a machine of the stated character h avlng novel means whereby the cutting tool may be accurately aligned with the s ace resi ing intermediate the adjacent en s of aligned track rails for beveling.
Another object of the invention is to provide a machine of the character set forth having a novel arrangement whereby milling operations may be performed on oppositely disposed rails without the pivoting of the entire machine.
These and other features and details of construction of the machine are set forth at length hereinafter and disclosed in the accompanying drawings, in which:
Figure 1 is a view in perspective of a machine embodying my invention positioned on a railway track ready for use;
Fig. 2 is an enlarged detached view in perspective showing the novel centering mechanism, placing the cutting tool in alignment 40 with the joint intermediate the two successively aligned track rails;
Fig. 3 is a view in section on line 3-3, Fig. 2;
Fig. 4 is an enlarged detail view in section of the mechanism transmitting power from. a redetermined source to the cutting tool; i 5 is a diagrammatic view showing the relation of the'cutting tool to the space intermediate the joint of adjacent track rails and Fig. 6 is an enlargeddiagrammatic view showin the relation of the cutting tool to the rol er grinding the cutter to correspond i with the surface contour of the track rail.
` In railway track work at the present time, 1t islvery often desirable to build up, by means of arc welding, the adjacent battered ends of successively aligned track rails. Subsequent to the building u of the ends,
vor joints intermediate the trac rails, the excess of the deposited metal is removed b grinding, making the joint relatively smoot with the remainder of the surface of the track rails. i
However, to enable the relatively smooth riding of a railway train over a joint so built up, it is necessary to cut or bevel the u per edges of the ends of the track rails to orm a recess therebetween to permit the wheels of a railway train to pass over the Ajoint in relatively smooth manner.
Heretofore the bevalling of the edges of the ends of rails has been done almost entirely by hand, which produced an uneven bevel and required a relatively long time. By this invention I provide a novel and eicient machine whereby the edges of adjacent track rails may be provided with a neat beveled cut -in an extremely short duration of time.
A machine of the type described, and made" in accordance with my invention comprises a frame consisting of side members 1, 1 and end members 2, 2. The extremitiesf'of the said end members 2, 2 in the present instance extend substantially beyond the frame members 1, 1 and support, in each instance, the
A carriage 6 is slidably mounted upon the side frame members ,1, 1 by means of rollers 7 rotatably mounted within the housings 8 and arranged `to ride upon the upper surface of the said frame members 1, 1. The carriage 6 in the present instance-ismaintained relative with the side frame members 1, 1 ofthe machine by the provision of rollers 9 mounted upon the laterally extending spindles of the depending rods 11, the said 'rollers 9 engaging the under surface of the pose of enabling the cutting of oppositely disment .ill
posed track rails without the complete turning about of the entire machine, I provide a circular table 14, constituting a part of the carriage 6 which is rotatably mounted upon a rail embracing the adjoining edge of the carriage 6.
The rotatable table 14 is provided with suitably positioned apertures arranged for engagement by a pin 15 acting agalnst the action of a spring embracing sald pin and residing in a houslng 15a. It should be noted that the positions of the apertures and the spring) pm 15 are such that upon engagey the pin 15 of the apertures, the position of the table 14 will be secured respectively in diametrically opposed positions and the cutting tool 16 carried by the table 14 will in each instance be' positioned normal to one or the other of the oppositely disposed track rails 5.
The cutting tool 16 is rotated in the present instance by power supplied by a suitable source of power designated generally as 17, having a shaft 18 extending therefrom, which is rigidly mounted upon the rotatable .table 14,l connection between the shaft 18 and the tool'16 being eiected by a novel arrangement described hereinafter in detail. A worm 19V is rigidly mounted adjacent the outer extremity" of the shaft 18 and arranged for rotation therewith, the extremity of the said shaft 18 and the worm 19 being enclosed in la housing 20 rigidly supported on the rotatabletable 14. The worm 19 is arranged for geared connection with a gear wheel 21 which is rigidly mounted upon a vertical shaft 22 rota-tabl mounted in bearings 23 and 24 respectivelj journaled in the housing 20 and the'housmg cover 25. The lower portion of the'shaft 22 is providediwith a vertical keyway26 arranged for sliding engagement with a .key 27 forming part of a cylindrical sleeve l 28vmounted .for rotation with the shaft 22 within the sleeve 30 slidably positioned in thefdrive housing 2O.l In the present instance the sleeve 28 terminates at its lower f extremity in a shaftl rotatably supported 'j in a bearing 32 journaled in a housing 33 `l".which is secured at its upper portion to the f' vertically movable sleeve 30, the said r-shaft S13-inthe present instance having a beveled gear-wheel 34 mounted Aat its lower extremcutting or milling tool 16. The movable sleeve 30, carrying the housing 33 which supports the milling tool 16 may be adjusted vertically by means of a screw 37 operated by a hand wheel 38, the said screw 37 being supported in a collar 39 forming a part of the cover of the housing 20.
The lower portionA of the screw 37 is emjbraced by a threaded collar 40 having a horizontally extending portion 41 arranged to slide in a slot 42 formed in the casing 20. The collar 40 in the present instance is connected with the vertical movable sleeve by means of a screw 43. The rotation of the hand wheel 38 in either clockwise or counterclockwise direction respectively raises or lowers the collar in the slot 42 which, by reason of the connection thereof with the sleeve 30 by the screw 43, results in the respective raising or lowering of the sleeve 30 which in turn raises or lowers the cutting tool 16 with respect to the track rail 5 upon which it is intended to operate. .The relative vertical position of the assembly just described, may be locked in any desired position by tightening the screw 44 against the outer wall of the vertically movable sleeve 30.
- For the purpose of accurately centering the cutting tool 16 with the space intermedif the said member 45 having an inwardly extending arm 47. A tongue 48 having one end thereof suitably pointed as at 49 is slidably rioopositioned below the horizontal arm 47, the
outer extremity of the said tongue 48 being bent downwardly as at 50- and having a pair of springs 51, 51 attached thereto and extending in the direction of the machine to theinner end of the arm 47 at which pointthey are respectively attached to a cross member 52.
The tongue 48 in the present instance is provided with an aperture arranged for reception of a pin 53 acting against a spring 54. The tongue 48 is also provided with a lever 55 for manually removing said tongue out of engagement with the space between the track rails 5, 5 the tongue 48being held in the outermost position by the said spring pressed pin 53 which moves into engagement with the aperture in the tongue 48. The tongue may be released and permitted to c ngage the space intermediate the track ra1ls 5, 5 by merely raising the pin 53 against the action of the spring 54, and the tension of -63 arranged for engagement by a lu The relative vertical position of the centering means may be adjusted by manually adjusting the member by means of the handle residing inthe slot 56 and when the desired vertical position is obtained, said member 45 may be secured in that position by tightening the screw 57 to engage a key 58 abutting the adjacent 'edge of the member 45 in a wedgelike manner.
For the purpose of effecting `a bevel cutting of the edges of the ends of adjacent rails which will correspond to the upper surface contour of said rails, I mount a roller 59 on a support 60, positioned adjacent each corner of the carriage 6, the said support extending downwardly from the under side of the said carriage substantially in alignment with the spindle 36 on which the tool 16 is mounted, and when the tool 16 is advanced into engagement with the track rails 5, 5 the rollers 59 will ride over the surface of the rails, transversely', and guide the cutter 16 into engagement with the rails to effect a bevel corresponding to the contour of the rails.
The cutting tool 16 is carried by the carriage 6 and advanced into engagement with the ends of the track rail by movement of the carriage 6 in the direction of the rails on the rollers 7 .K The advancement of the carriage 6 is effected by means of a handle 61 ivotally mounted about a stud 62 extending aterally from the bracket 62a on the carria e 6.
In t e present instance, the lower extremity of the handle 61 is provided with a slot 64 formed on the frame member l, and a out which the said handle 61 is pivotedto advance the carriage 6, carrying the cutter 16, in the direction of the rail to be cut. For the purpose of disengaging the slot 63 in the handle 61 from engagement by the lug 64, the said handle 61 may be pivoted about the rod supported in the sleeve 66 permitting relative pivoting of the handle 61 normally to the longitudinal axis ofthe machine, the purpose for which will be set forth hereinafter.
In' operation of the machine, with said machine residing upon standard railway track rails 5, 5, with the carriage 6 and turn table 14 at respective positions, as disclosed in Fig. 1 of the drawings, the cutter centering means, shown in Fig. 2 of the drawings,
is adjusted to a vertical position which will permit the end 49 of the tongue 48 to enter the space intermediate the rail heads of successively positioned trackrails, the vertical position of the above being secured by tightening of the aforementioned lock screw 57. The pin 53 is then raised against the action of a spring 54, disengaging said pin 53 from the aperture in the tongue 48, permitting the springs-51, 51 to advance the tongue 48 into engagement with the space intermediate the ends of the particular track rails 5, 5:V The turn table 14 carrying the cutter lfis then'locked in alignment with the cutter centering tongue 48 by the spring pressed pin 15 which engages one of the aforementioned'apertures suitably positioned on the table 14 to insure the positioning `of the cutting tool 16 at right angles to the longitudinal axis of the track rails 5, 5.
' The cutting tool 16 carried by the carriage 6 is adjusted vertically with respect to the track rails 5, 5 by turning the hand wheel 38, turning the screw 37 which` respectively raises or lowers the sleeve 30 supporting the cutting tool 16, the power from the source 17 being imparted to the cutting tool 16 through the shaft 18, the worm gear and wheels 19 and 21` respectively, and shaft 22 and sleeve 28 keyed to said shaft as described hereinbefore.
The cutting tool 16. is moved into contact with the track rails 5, 5 by rocking the handle 61 about the lug 64 which advances the carriage 6 on the frame 1, 1. When the present operation has been'completed and itis desired to perform a similar operation onopposite track rails, the handle 61 is disengaged from the lug 64 by pivoting said handle about the spindle 65. The carriage is summarily moved to a position adjacent the opposite end ofthe machine and the slot 63 in the lower extremity of the handle 61 placed in engagement with a similar lug 66 by a similar operation. The pin 15 firmly securing the turn table 14 in position, is released against the action of the spring and the table rotated to the-opposite track rail at which position the spring pressed pin then engages a second suitably positioned aperture in the table 14 securing the position of the cutting tool normal to the said track rail. The accurate centering of the cutter 16 with res ect to the space intermediate adjacent trac rails is effected in substantially the same manner as described above b means of a ton ue 48 similarly mountedy on the opposite en member 2 of the machine.
A machine of the character disclosed and* made in accordance with the preceding speriication is useful and highly desirable for railway work, being simple in operation and relatively light in weight permitting the operation and handling thereof by a single operator.
While I have disclosed the embodiment of my invention for the purpose of description.
it will be apparent that certain changes and modifications may be made therein without departingfrom the spirit of the invention.
