SNOW CLEARING APPARATUS FOR RAILROAD SWITCHYARDS May 15, 1962 Filed April 1, 1960 INVENTOR'.
A.E. PYKE AGENT.
United States Patent 3,034,236 SNOW CLEARING APPARATUS FQR RAILRGAD SWITCHYARDS Albert Edward Pyke, 269 Manse Road, Scarborough, Ontario, Canada Filed Apr. 1, 1%0, Ser. No. 19,254 Ciairns. (Cl. 3725) The invention relates to apparatus for clearing snow from relatively complex sections of railroad track, for example, cros-overs, switch points and the like. Under severe weather conditions such complex portions of track require more or less constant maintenance to prevent them from becoming clogged with snow or ice, rendering the same more or less inoperative.
Such snow clearing apparatus as has been available hereto-fore is, generally speaking, adequate for clearing relatively deep snow, and also for clearing straight or socalled tangent track. Conversely, however, such equipment has not always been capable of clearing the more complex sections of track, as for example, are met with in railway switchyards, and indeed in many cases, such operations have been performed by manual labour.
Many of the difliculties associated with this particular problem arise from the relative complexity of the track, and the vital necessity for clearing snow and ice from the various recesses and crevices formed thereby in order to free the same for movement.
Accordingly, it is a general objective of the invention to provide snow clearing apparatus adapted for clearing snow out of recesses or crevices or the like in an expedient and efiicient manner, and which is both economical to make and relatively simple and economical to operate. More specifically, it is an object of the invention to provide such apparatus which is adapted for mounting on a vehicle.
Still more specifically, it is an object of the invention to provide apparatus having the aforementioned advantages in which the snow clearing apparatus is operable to pick up the snow lying on the road bed travelled by such vehicle and to throw it forwardly of the vehicle and to clear such thrown snow to one side of the road bed.
It is a further object of the invention to provide such apparatus which is particularly adapted and suitable for operation in railway switch yards and the like.
The invention seeks to provide the foregoing and other advantages which will appear from the following description of the preferred embodiment of the invention by the provision of snow clearing apparatus for use on a vehicle, consisting basically of a sweeping element for throwing snow forwardly of such vehicle, and a disposal device for receiving such snow and disposing of it to one side of the vehicle.
A preferred embodiment of the invention will now be described with reference to the following drawings, in which like reference devices refer to like parts of the apparatus throughout the various views and diagrams, and in which,
FIG. 1 is a diagrammatic plan view partly in section showing a snow clearing vehicle, fitted with the snow clearing apparatus according to the invention,
FIG. 2 is a sectional side elevation of the snow clearing apparatus shown in FIGURE 1, showing part of the vehicle to which it is attached, for clarity,
FIG. 3 is a schematic diagram of a detail of the sweeping element of the instant snow clearing apparatus showing the same in three successive positions during operation, and
FIG. 4 is an enlarged section of the snow clearing apparatus in isolation along the line IVIV of FIGURE 1.
Before describing the snow clearing apparatus of this preferred embodiment, a brief description will be given of the snow clearing vehicle, although it will be appreciated, that the invention is not to be considered as limited to use in conjunction with this particular vehicle which is here described for illustrative purposes only.
' Accordingly, from FIGURES 1 and 2, it will be seen that the snow clearing vehicle V consists of a frame 10 mounted on wheels 12, adapting the same for use on railroad tracks T, motive power being supplied thereto by an engine and drive mechanism (not shown) driving wheels 12 in known manner. Such vehicle V may also be provided with a cab C at the forward end thereof, and may optionally be provided with further conventional accessories, for example, sand boxes (not shown) may be provided adjacent wheels 12 for use in the elimination of slipping or skidding in bad weather.
Dealing now with the snow clearing apparatus of this preferred embodiment of the invention, it will be seen that this is comprised of the sweeping element 14 supported for rotation by arms 16 and 16 and driven by sprocket 18, keyed to shaft 20 thereof, which is, in turn, connected to sprocket 22 by means of chain 24, sprocket 22 in turn being driven by shaft 26, sprocket 28, chain 30 and sprocket 32 connecting the same to engine E situated towards the rear of vehicle V.
In order to adjust the height of sweeping element 14 in relation to the road bed R or other surface which is being cleared by the instant apparatus, arms 16 are swingably attached to frame 16' of vehicle V at journals 40, rendering sweeping element 14 swingable between upper and lower positions. Any suitable means may be provided for raising and lowering sweeping element 14 for example, the hydraulic lift 42 swingably attached to frame 10 and to cross bar 44 extending between arms 16.
In order to lock sweeping element 14 at any desired elevation, a hydraulic lock (not shown) may be associated with hydraulic lift 42 for the purpose, in known manner.
In order to receive and to dispose of snow and ice thrown forwardly and upwardly by sweeping element 14 disposal device 46 is provided, located forwardly of sweeping element 14 in receiving relation thereto and supported in such location by bars 43.
In order to carry the snow and ice received by catcher 59 well clear of the road bed R which is being cleared, catcher Si? is provided with a cylindrical extension forming a spout 72 extending beyond the width of sweeping element 14, and it will be seen that conveyor do in fact extends into spout 72 for pushing said snow from catcher 5G and into spout 72 with sufiicient force to eject the same therefrom through opening 74.
In order to adjust the height of disposal device 46 in relation to sweeping element 1d, bars as are mounted for swinging about shaft 2t} of sweeping element 24, and may be adjustably fixed in any desired position by suitable adjustment of chains 76 fastened to upright posts 78 located oni-bars 48 and extending therefrom to slotted holes 80 in crossbar 44.
In operation vehicle V may be set in motion, which, generally speaking, will be relatively slow, though obviouslydepending upon the particular circumstances of operation. At the same time sweeping element f imsy also be set inv motion, its direction of rotation being counter to the direction of motion of vehicle V, and by operation of hydraulic lift 42 its height may be set so that ilails 38 are just contacting the road bed R along which vehicle V is travelling, though preferably such contact should only occur at the tips of flails 38 in order to avoid wear on these members, and also loss of power. Rotation of sweeping element 14 will also cause rotation of spiral pusher or conveyor 69 located in snow disposal device 46, through sprocket 7%, chain 68 and sprocket 66.
As sweeping element 14 rotates, flails 38 will apply continuous blows to snow and ice located on the road bed breaking up and dislodging the same and will thereafter throw the same forwardly of vehicle V and into the mouth 54 of catcher 50. It is here noteworthy that, by operation of sweeping element 14 in a direction counter to the direction of movement of vehicle V flails 33 are caused to strike the snow and ice on road bed R in a generally forward and upward direction causing the same to be thrown r impelled forwardly of the vehicle V. By adopting this mode of operation, it will be seen, that any snowor ice which does not reach catcher 5t; and falls onto the road bed R oncemore will still be in front of sweeping element 14, and will be brushed or swept thereby continually until the'same is held by catcher 50. Under certain operating conditions, this particular feature of the apparatus has caused a wall of snow to build up between lip 56 of catcher 5d and the snow lying on the road bed R in the path of sweeping element 14, thereby preventing the escape of Snow forwardly of catcher 50 and guiding the same into the open mouth 54 thereof. While operating in this manner flails 38 mayin fact be deflected to a greater or lesser extent'by contact with the snow or ice, more or less in the manner indicated in FIG. 2 thereby applying substantial blows thereto on impact and thereafter applying a brushing action upwardly and-forwardly of vehicle V in the direction of disposal device 46.
When a complex section of track is encountered, and,
track T1, for example, but such deflection will be only momentary. and will. not substantially inhibit the scavenging action of flails 38 on either side thereof as is shown in FIGURE 3. It will be understood that track T1, in this illustration is oblique to the axis of rotation of drum 3% and shaft 20, running diagonally across the path of vehicle V, and forms crevices or declivities at the intersection thereof with the tracks T upon which vehicle V is running. enabled to reach into such crevices and clear the snow and ice therefrom, freeing such section of track for switching for example.
Gnce in catcher 50 snow andice is pushed axially therealong towards spout 72 by the rotation of spiral conveyordfi, being finally ejected through opening 74 in spout 72 alongside the road bed R, and at some distance therefrom. It is. to be observed that'in order to avoid block-ages occurring in disposal device ail-spiral conveyor 66 shouldbe so designed and driven as to operate at only about half capacity, that is to say, with snow. extending therearound for only approximately thereof.
- Where desirable, disposal device 4drnay be relocatedwith respect to sweeping element 14 by merely raising both sweeping element 14 and disposal device 46, by operation of hydraulic lift 42, placing blocks (not shown) under disposal device 46 and-lowering sweeping element 14 once more, after which chains 76 may be either shortened or lengthened and refastened in slotted holes 80. The positioning of the instant snow clearing equipment ahead of vehicle V and of all track engaging means, such as wheels 12, as illustrated throughout the drawing is not only to facilitate its adjustability as aforesaid but especially also to enhance its eificiency in use on the short complex track sections found in the railroad switch yards for which it was designed as well as in many other and more obvious respects.
The foregoing description of a preferred embodiment of the invention is here made by way of example only, and it is not thought that theinvention is limited to the specific construction illustrated other than as specified in the appended claims which are intended to include all modifications which do not depart from the spirit of the invention.
