FIGURE 6 is `similar to FIGURE 2 but of a variant form. U
An embodiment for removing tie ends is shown in FIGURE l mounted on a vehicle base shown generally as 10. The vehicle base may be a railway machine with 3,210,046 Patented Oct.- 5, 1965 ice the usual anged Wheels 11 mounted on heads 12 of rails 15. The rails, of course, are mounted on ties. The end portions 19 and 20 are shown in a trench 21 opened by removal of a central tie portion. The trench is formed by the ballast 22. The usual tie plates below the rails have been omitted in the drawings although the tie ends may be removed in the manner set forth hereinbelow with the tie plates in place.
The vehicle base or railway machine will not be described in detail because such machines are well known in the art and are not essential to the practice of this invention. It may, however, be mentioned that a frame 16 is present to hold various units, and a gasoline engine 23 or the like may be mounted to run the machine. A hydraulic pump 26 may be driven by the engine to supply high pressure hydraulic fluid to various cylinders and drives through appropriate connectors, not shown in detail, controlled by a suitable lever operated valve unit 27. The unit may be self propelled or otherwise. The details of the hydraulic circuit may be Istandard and are not important. Suitable hydraulic lines convey pressure fluid to and from thrusting cylinders 30 and 31 through connections 32, 33 respectively. Line 34 provides pressure to a lift cylinder 35 through connections 36.
The thrust cylinders are connected to thrust levers shown generally at 37 and 38. The levers are shown mounted on one end of the vehicle base but it may be otherwise. The levers are shown with lower lateral outwardly disposed arms such as- 40 with a butting face made of a bar 41 secured to the end thereof.
The thrust cylinders 3i) and 31 are aligned and formed into a single unit which is 'lowered and raised by rams 44 of lift cylinders 35 lconnected to them by a pin joint 47. The lift cylinder is cla-mped between trunnions or blocks 46, one on each side and pulled together by bolts 4S. The blocks in turn are pivoted in aligned bearings 46a, one for each block, which are in turn mounted on an extension of the frame, as at 46b in FIGURE 4. The blocks 46 have extensions 46c which engage springs 46d carried by plates 46e mounted ion the frame extension 46f, as shown in FIGURE 5. Thus, while the lift cylinder is free to pivot in bearings 46a, the springs resist or limit this movement. A plate 49 is shown xed to the top of the lift cylinder. The opposed ends of the plate hold the pivoted inner ends 50, 51 of links 52 and 53. The outer ends of the links are pivoted to the top of the levers at 54 and 55 to form a composite linkage.
The thrust cylinders have rams 56 and 57 which are connected at their outer ends to upper lateral arms 59 and 60 of the levers. Each ram is ixed to a collar 61 which receives a transverse pin 62 held in the upper arms 59 and 60 by means such as cotter pins 64.
Gauge members generally shown as 72 and 73 are associated with each lever. FIGURE 4 shows the details of this connection as well as other details of one lever. This lever is seen to have spaced side walls 76 and 77, and the lever is made structurally rigid by connecting vertical walls 78, 79 and horizontal connecting walls such as 80 and 81.
The trust cylinders such as 30 have an upper Vilange connection 82 and a lower flange 83 to which is connected extending member 84 of the gauge member 72. The connection is not shown but may be conventional welds, bolts or the like. The extending member has a vertical plate85 to which is fixed a horizontal bar or linger 86. The horizontal bar is shown seated, insulated and secured in horizontal channel S7 by bolts or the like 88. The vertical connecting plates such as 79 have a clearance 91 through which extending member 84 may pass when the lever moves laterally against the tie ends. The upper and lower lateral arms of the levers are sufficiently spaced apart so that the gauge member and rail may enter such space when the thrust face of the lower lateral arm butts against the inner end of the tie portions.
The use, operation and function of the invention are as follows:
As is well known, ties in track require frequent replacement due to wear, rot, vermin, etc. Cutting worn ties in three parts and removing the center and end pieces separately is old. Removing the ends, under each rail, has been troublesome. The spikes are usually removed, but the tie plates may be left in place.
Basically the present invention is concerned with providing a generally horizontal outward thrust between the tie ends which will be effective against both at the same time, so that the tie end offering the least resistance will not use or absorb all of the force. This is to say that both tie ends will be ejected or kicked out at approximately the same time even though one of them may and will offer less resistance than the other.
It is inevitable that the tie ends will offer different resistance. Thus, if the outward thrust is only counterbalanced by or between the tie ends themselves, one tie end will be kicked out--the one offering the least resistancewhile the other will stay in place, until the first one is completely out.
This invention has the advantage that the thrust mechanism, be they hydraulic cylinders or otherwise, is coordinated so that both tie ends are pushed out at about the same time, thus substantially reducing the time required for the machine to go through a full cycle.
In the form shown, the abutments 85 on the gauge members 72 and 73 are a fixed distance apart, slightly less than the distance between the gauge faces of the rails. For example, standard gauge in the United States is 561/2 inches, so the faces 85 may be 55-1/2 inches apart, allowing 1/2 inch clearance on each side. This is only an example.
They should be of sufiicient clearance so that no diliculty is encountered in lowering the mechanism into the trench.
The mechanism may he carried by a separate wheel car, either self propelled or otherwise. Or it may be 'carried on another unit, for example, a tie cutter or on a separate mobile ground contacting unit.
The arrangement shown has the advantage that the lift cylinder may be used to raise the entire mechanism well labove the rails during travel. Also, during operation, the push cylinders 30 and 31 are not lowered in the ballast but remain well above it. Thus, the piston rods will not be scored or damaged by the ballast.
When the mechanism is lowered into a trench, each of the push cylinders is energized. If, for example, the tie end on the left, designated as 19 in FIGURE 2, has the least resistance, it will start moving iirst. As both push cylinders extend, the cylinders and gauge members will shift to the left until the gauge face 85 abuts the left rail. This is almost instantaneous. Thereafter, the tie end on the right, designated 20 in FIGURE 2, will start to move. At the same time the left tie end continues its movement.
Had this been reversed, with the right tie end 20 offering the least resistance, it would start to move first until gauge member 73 contacted the right rail. Thereafter, left tie end 19 Will begin to move. Again, the time involved from the movement of the first tie end until the second one starts to move is quite small. The result is that, in effect, both tie ends are pushed out at the same time.
It should be emphasized that the push cylinders and 31. are separately connected to power source so that each will extend or retract at the same time. One will not rob or hog all of the high pressure iiuid.
While the gauge members are shown as having lingers 86 in FIGURE 2, this is not absolutely necessary. Since the lowest position of the mechanism may be determined by the levers 37 and 38 hitting the bottom of the trench, these depth gauge fingers may not be necessary.
In FIGURE 6 a variant form has been shown in which the structure is basically the same except that the inner portions or heels of the levers carry a free socket composed of a round welded or otherwise secured on one lever, and an angle iron 102 on the other. These are positioned and proportioned such that when the push cylinders fully retract bringing the levers together, the round fits in the angle. Thus, the levers are vertically interlocked and tend to stay together. This has the advantage that on a curve where one rail is higher than the other, the mechanism would tend to pivot about the lift cylinder bearing against the resistance of springs 46d. The joints 100 and 102 prevents one lever from dropping and the other rising. The joints, however, do not hinder the operation of the device in kicking or pushing the tie ends out but merely keeps the over-all linkage properly disposed when the device is working on super elevated track.
The springs allow a limited degree of pivoting of the lift cylinder, but not much. Just enough to prevent the over-all structure from being rigid and thereby protecting it, but without in any way affecting its basic operation.
As shown in FIGURE 6, the pushing or contacting faces 104 may be half rounds with the blunt face outward and disposed at an angle corresponding somewhat to the angle of the cut face normally encountered on the tie ends. This angle will depend somewhat upon the type of equipment used to cut the tie into three pieces. The angle shown on the ends of the inside of the tie ends of the drawings normally result from using the machine and method disclosed in application Serial No. 161,546, iiled December 22, 1961.
While the machine has been disclosed as usable primarily for pushing out the tie ends in a tie replacing operation, it should be understood that it may have other uses. For example, it may be used to remove ballast in the crib from under the rail base so that snow, water, etc. does not collect. The toes or feet at the bottom may be somewhat elongated for this purpose, and it will be noted that the feet at the bottom of the levers in FIGURE 6 are somewhat longer than those in FIGURE 2.
While the preferred form and one modification has been shown and described, it will be understood that suitable additional modifications, changes, substitutions and alterations may be made without departing from the inventions fundamental theme. It is therefore wished that the .invention be unrestricted except in view of the prior art.
