Definitions
- This invention relates to an apparatus and method for placing and attaching rail insulators, and more particularly, to an apparatus and method for attaching clips and insulators to secure the rail to the railroad tie.
- the present invention is an apparatus and method for distributing and applying rail clips and insulators to ties and track.
- the apparatus includes a source to power the car down the track, a rail manipulator to aid in placing insulators adjacent to the tie and rail, supply compartments for the insulators and clips, loading areas for workers to place the clips and insulators, and the clip applicator.
- the car is equipped with a crane to load the compartments with clips and insulators which are placed so that the workers have easy access to place the clips on the ties and rails.
- the applicator includes a framework which supports two pairs of squeezing members.
- the applicator moves with the car and yet moves independently to stop momentarily to apply the clips of each tie as the car moves continuously down the track.
- the present invention may be operated efficiently with four workers positioned in the car to provide a smooth application of clips and insulators on a continuous basis adjacent to the rails making up the track.

- Fig. 9 is a perspective view of a portion of a clip applicator built in accordance with the principles of the present invention.
- an applicator car 10 is shown according to the present invention.
- a rail car 12 is equipped with an engine 14 and power truck 16 to power the car.
- the applicator car 10 is self-powered.
- a diesel engine 14 is utilized with the invention.
- the engine 14 powers hydraulic and electrical systems which manipulate and power the other aspects of the invention.
- Power truck 16 is driven by the engine 14 to move the car along the rails.
- the power truck 16 is a two speed unit.
- the power trucks 16 and idler truck 1 include axles, wheels, bolsters, springs, center castings, and other known parts to carry the car and move it for use.
- a pump (not shown) powered by the engine 14 moves the gag 16 at either a high traveling speed or a low speed suitabl for propelling the car prior to entering the work mode.
- the low speed is approximately two miles per hour and the traveling or high speed is approximately thirty-five miles per hour.
- Yet a further advantage of the invention is that it can be taken out of gear and then pulled by a regular train at higher speeds to move from work area to work area.
- a cab 27 is used to control car 12 in the travel mode only, and contains a tachometer, engine temperature gauge, voltage meter, air pressure gauge, throttle, brake and on/off control (not shown) .
- Speed controls 18 are utilized to control the hydraulic flow to the pump and to put the car 10 in the work mode.
- the car 10 In the work mode, the car 10 is moved at approximately 1/4 mile per hour (24 feet per minute) so that the workers 24, 95, 3 and 4 may arrange the work pieces 5, 40 adjacent to rails 32 such that they may be clipped to the ties 29, 33, 34, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81 at an acceptable speed.
- a speed of 1/4 mile per hour allows eight to twelve ties per minute (twenty-four feet per minute) to be manipulated and clips 5 applied to the ties 29, 33, etc. This gives the workers 3, 4 approximately five seconds per tie to apply clip 5, obtain an additional clip 5, and move ahead to the next tie.
- the track 31 is comprised of rails 32, concrete ties 29, 33, 34, etc. and steel shoulders 36 which are embedded in the concrete tie.
- the insulator 40 is placed between the steel shoulder 36 and the rail 32.
- a clip 5 is then positioned as shown in Fig. 5 and, after placement and securing steps are performed, fits into the shoulder 36 and over the insulator 40 to secure the rail 32 to the tie.
- the shoulder 36 is attached to the concrete tie by integrally formed anchor 42.
- the rail manipulator 20 is shown operatively connected to the car 12.
- the rail manipulator is manufactured by Herzog.
- rollers 22 are utilized as a lining and shifting mechanism to enable the worker to manipulate the rail 32 laterally up to 3/16 of an inch each way in order to permit placement of the insulator between the shoulder 36 and the tie.
- Workers 24 and 95 in the work compartment 26 place their feet 7 on the manipulator controls 28 to "line left” or “line right” the rollers 22 and cam followers 100 to line the rail 32 as needed.
- the rollers 22 engage each rail 32 of the track 31 and workers 24 and 95 control the rollers 22 for each side of the track 31.
- the work station 26 includes a frame work 44 which includes four seats 46 for four workers. As mentioned above, the seats 46 are staggered so that the workmen can work without interfering with each other. Proximate the work station 26 and convenient to each worker is an insulator bin 50 and clip bin 52. As shown in Fig. 1, the bins 50 and 52 are connected to larger hoppers 54 and 56 which contain the insulators and clips respectively. A crane 58 is powered and operatively connected to the car 12 so that clips 5 and insulators 40 may be loaded into the bins 54, 56 for use by the workers. In the preferred embodiment, approximately three thousand insulators 40 and approximately three thousand clips 5 may be loaded into the hoppers 54 and 56 for utilization. Further, a deck 60 of the frame work 12 may carry additional boxes and barrels of clips and insulators.
- the applicator 66 includes a frame work 68 which is connected to a pair of satellites 70 and 72.
- the satellites 70 and 72 are sequenced to automatically stop and apply the clip 5 which has been placed by the worker on each side of the rails 32 of the track 31.
- the satellites 70 and 72 are controlled independently so that they apply the clips 5 to every rail 32 and tie as the entire apparatus 10 moves down the track 31.
- Each satellite 70, 72 contains two opposed members 74 and 76 which pivot around shafts 78 and 80.
- Pads 82 and 84 are connected to members 74 and 76 to contact the clips 5 as shown in Fig. 4. Expansion and contraction of the pads 82 and 84 are controlled by cylinder 85.
- An electronic signal is sent to cylinder 85 allowing the hydraulic pressure to close pads 82 and 84 in Figs. 8 and 9.
- an electronic variable timer (not shown) , nominally set at approximately 1.5 seconds, produces the appropriate signal, the hydraulic controller will reverse the flow in the cylinder 85.
- a second set of controls 92 are located on the inboard side of the "LEAD" insulator operator 95 which allow one operator or worker to change the travel speed, engine throttle position, control a horn, control the brakes or reset the sensors of the satellites as needed.
- Worker 95 is able to "lock out” the operation (not shown) in the cab 27 while car 12 is in the work mode.
- the controls include means for receiving a report regarding the oil pressure, rpm, hydraulic temperature, engine temperature, air pressure, brake condition, etc. of the engine 14 so that the worker knows how the overall apparatus 10 is working.
- the diesel engine drives the power truck 16 and moves the truck 1 in the direction shown by arrow 9 in Fig. 2.
- the workers 24 and 95 utilize the rail manipulator to place the plastic insulator 40 adjacent the steel shoulder 36 and rail 32.
- the apparatus is moved forward so that the second set of workers 3, 4 may place the clip 5 on the insulator 40 for application.
- the satellites 70 and 72 of the applicator 66 then apply force via pads 82 and 84 to move the clip 5 into a secure position onto the shoulder 36, rail 32 and the tie. This operation is continued for the length of the track which is to be secured.
- the applicator structure 66 resides in an area defined by the width 11 of the track 31 and the distance 13 between workers 3, 4 and power truck 16.
- the distance 13 must be large enough to accommodate applicator 66 plus the distance the car 12 will travel while the applicator 66 is stationary over tie 34 during the clipping or squeezing operation.
- An additional amount must also be added to distance 13 as a safety factor to ensure that car 12 can be brought to a stop without imposing excessive loads on applicator 66.
- the applicator 66 includes a frame 68 which is formed, in a preferred embodiment, as two parallel tubes, each residing above and being substantially coplanar with its respective rail 32.
- the frame 68 serves as the base upon which satellites 70 and 72 are mounted, as well as a reference plane for an electronic switch (not shown) that is activated by touching each tie.
- Frame 68 also houses an emergency stop sensor (not shown), as well as a recovery (or ready) sensor which initiates the -restarting of the sequence of applying (or squeezing) the clip 5 into the concrete tie shoulder 36.
- the frame 68 is secured in a desired position over the rail 32 by use of standard small rail wheels 15 and 17 mounted on axle frames 19 and 21, respectively.
- Downward pressure is applied to each satellite 70, 72 by means of hydraulic cylinders 23 and 25 in order to ensure that each clip 5 is applied properly and that the satellites 70, 72 do not derail. Cylinders 23 and 25 also lift and retract applicator 66 when the car 12 is in the "travel mode.”
- the sequence of operation of the satellites 70, 72 after the hydraulic and electrical system (not shown) -are energized is as follows: first, the car 12 moves at a constant speed of approximately 24 feet per minute.
- the satellite 70 for example, is in a most forward position. That is, the telescoping cylinder 23 is in a relatively compressed position, satellite 70 is over tie 59 and the sensor (not shown) on the satellite 70 senses the presence of tie 59 and engages the hydraulic cylinder 835 This hydraulic cylinder squeezes the two clips 5 into place in the concrete tie shoulder 34. While the satellite 70 itself has stopped over the individual tie 59 the car 12 moves ahead at 24 feet per minute as can be seen by the position of satellite 70 in Fig. 7.
- the cylinder 85 When the cylinder 85 has squeezed a constant pressure for a period of nominally 1.5 seconds, it electronically releases and pads 82 and 84 are spread apart due to the action of cylinder 85. This release is based upon time with a constant pressure of approximately 2,000 psi. The damage to the clip 5 from overdriving is prevented by having a manual but adjustable stop 89 to control the cylinder stroke.
- the release of the clip 5 by satellites 70, 72 (when fully recovered) trips an electrical switch (not shown) that engages a hydraulic cylinder (not shown) , which is attached to the frame, to push the applicator 66 back towards the front of car 12.
