TIE-TAMPING MACHINE.

To all whom it may concern.

Be it known that I, Gnonen F. Wnrss, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a new and useful Tie-Tamping Machine, of which the following is a specification.

This invention relates to machines for tamping dirt or ballast under and against rail-road ties.

The purposes of the invention are: to provide in connection with a car adapted to-be propelled on a rail-road track, reciprocating tamping means actuated by a motor on the car and adapted to simultaneously tamp the ballastunder and against both sides of the ties and likewise especially adapted to tamp the ballast under and against those parts of the ties which are immediately under the rails, the tamping being done simultaneously in four different directions namely, from both sides of the tie and from both sides of the rail; to provide means for convenient and efi'ective control of the tamper-s when in use; to provide means for putting the tainpers out of commission; to provide means for raisin the tam aers and su 3 aortin them in their raised position when not in use; to provide tampers having relatively slow upward movement and accelerated downward movement, to utilize the full percussive force of the tampers; to providea machine comprising a plurality of sets of tampers operable separately or jointly; to provide means for propelling the car by the same motor that actuates the tampers; and to details of construction hereinafter set forth.

"With these ends in view my invention consists in the novel features of construction and combinations of parts shown in the an neXed drawings to which reference is hereby made, and hereinafter particularly described Specification of Letters Patent.

Patented July 3, 1917. Serial No. 129,091.

Fig. i is a vertical transverse section on the of Fig. .1; Fig. 5 is a broken vertical section on the line Y. Y. of Fig. 1; Fig. 6 is an enlarged partial elevation of the left-hand tamper frame and appurtenances, as viewed from the center of the machine looking toward the left; Fig. 7 is an enlarged detail of a part of one tamper frame, a cradle mounted thereon, and means for oscillating the cradle; Fig. 8 is an enlarged transverse section on the line Z. Z. of Fig. 7 looking upward; Fig. 9 is an enlarged transverse section on the line W. W. of Fig. 7 looking downward; F ig. 10 is a broken vertical section on the line V. V. of Fig. 7 Figs. 11 and 12 are respectively an enlarged top plan and an enlarged rear elevation of the main drive shafts and gears; and Fig. 13 is an enlarged detail of the means connecting the wiper shafts with the lifter-bars.

Similar reference characters designate like parts in the different views.

The main frame 1 is preferably of angle bar. The axles 2 are suitably connected with the frame 1. The supporting Wheels 3 are loose on the axles, and are gaged to run on the rails of the track. Platforms 4, one at each end of the machine accommodate the operator. Standards 5, 6, and 7 (Figs. 1, 1, 11, and 12) and bearing blocks 8, 9, 10, and 12 are stationary on the main frame.

A shaft 13 is mounted to rotate in suitable bearings on the standards 5 and 6. A similar shaft 141 is mounted to rotate in su1t able bearings on the standards 6 and 7.

Intermeshing gear wheels 17 and 18 are secured on the shafts 13 and 14 respectively.

clutch-member 19 is adapted to slide on the shaft 13. A sprocket wheel 20, loose on the shaft 13, has a clutclrmember 21 adapted to be engaged by the clutch-member 19 to cause the sprocket wheel to rotate with the shaft. The sprocket wheel 20, is connected to actuate one of the wiper shafts as hereinafter described.

A sprocket wheel 22 is secured on the shaft 14. Clutch-members 23 and 2a are adapted to slide on the shaft 14. A sprocket wheel 25, loose on the shaft 14, has a clutchmember 26 adapted to be engaged by the clutch-member 2-3. A sprocket Wheel 27,

loose on the shaft 1 1, has a clutch-member 28 adapted to be engaged by the clutch-member 24. The sprocket wheel 25 is connected to actuate one wiper shaft as hereinafter described.

The shaft 15 rotates in the bearing blocks 8 and 9. Sprocket wheels 29 and 30 are secured on the shaft 15. The motor 31, preferably a gasolene engine, is suitably located on the main frame. A sprocket chain 33 connects the sprocket wheel 32 on the motor shaft with the Wheel 29 on the shaft 15. A sprocket chain 3% connects the sprocket wheel 30 with the sprocket wheel 22- so that the shaft 15 drives the shaft 1 1 at a reduced speed. The shaft 1& is connected to actuate oneset of tampers and the shaft 13 is connected to actuate the other set of tampers. The gear 18 on the shaft 14: meshes with the gear 17 on the shaft 13 to cause the shafts to rotate in opposite directions.

The shaft 16 rotates in the bearing blocks 10 and 12. Sprocket wheels 35 and 36 are secured on the shaft 16. A sprocket wheel 37 is connected with the hub of one of the wheels 3. A sprocket chain 38 connects the wheels 27 and 35 so that the shaft 1 f drives the shaft 16 at a reduced speed, and a sprocket chain 39 connects the wheels 36 and 37 so that the shaft 16 drives the connected wheel 3 at reduced speed.

The clutch- members 19 and 23 are effective to control the operation of the wiper shafts and the clutch-member 24: is effective to control the operation of the car-propelling means. The construction described admits of operating the tampers at a relatively high speed but less than the speed of the motor, and propelling the car at a relatively slow speed and starting or stopping the car as may be expedient.

There are two movable tamper frames 51, one near each end of the machine. Each tamper frame is equipped with means for varying the inclination of the frame relative to the track being operated upon, and is,

equipped with a plurality of reciprocating tempers, means for actuating the tampers and means for changing the position of the campers relative to the ties and relative to the rails. Both tamper frames are alike, and on both frames the tampers are alike, the means for actuating the tampers are alike, and the means for adjusting the tampers with respect to the ties and the rails are alike, it is therefore necessary to describe only one tamper frame and appurtenances.

Parallel vertical side frames 10 (Figs. 1, 2, and 3) of approximately arch-shape, are rigid on the main frame. Parallel vertical bars 41 central with respect to the side frames 10 are rigidly secured on the frames. Arch-shape lifter bars 42 turn on pivots 913 on the vertical bars 41.

The axis of one pair of pivots A3 is in line tamper frame give with the axis of the shaft 13 and the axis of the other pair of pivots 4:3 is in line with the axis of the shaft 14:. This relation of the parts serves to prevent slack in the sprocket chains which drive the wiper shafts.

Levers 4A are rigidly connected with the lifter'bars 42 and are equipped with dogs 4:5 adapted to engage in notches A6 in the frames 10. Springs 47 surround the levers l4 and act to normally hold the dogs in the notches. Bearing blocks 18 are secured on the lifter .bars 12. The lifter bars A) have arched parts 12 which permit the tamper frames, which projectbeyondthe lifterbars, .to move under the arches when they are manipulated by the handlebar 68 to assume different positions indicated by dotted lines in Fig. 2.

Each lifter bar 4:2 is capable of movement independently of the other lifter bars. The wiper shafts 4L9 are mounted on the pairs of lifter barsrespectively. It is at times desirable to change the position of the lifter bars ,while the tampers are in operation and to effect this it is necessary .to providemeans pivotally connecting the shafts 49 with the lifter bars 42 so that if one lifter bar be at rest and'the other lifter bar of thesame pair be raised or lowered, the boxes in which the wiper shaft turns will automatically adjust themselves to the changed position vof the 4-9. A sprocket chain 7'? connects the wheels 20 and 76 so that the wheel 21 actuates the wiper shaft. A sprocket wheel 76 is sta-' .tionary on the shaft 49. A sprocket chain 77 connects the wheels 25 and 7 6 so that the wheel 25 actuatesthe shaft 41-9.

The rectangular tamper frames 51. are preferably of angle iron.

Brackets 52 secured on the tamper frame turn on the wiper shaft and connect the tamper frame with the shaft so that it may turn on the shaft to change the inclination of the tamper bars relative to the ties.

Inclined braces 53 (Figs. 3 and 7) rigidly connected with the horizontal rails of the rigidity to the frame. is mounted on an oscilwill now be described.

Each tamper bar lative cradle which The cradles and the tamper bars mounted.

thereon are all alike so it is necessary to describe only one cradle and one tamper bar.

The cradle comprises two parallel angle bars 51 pivotally connected with the lower rail of the tamper frame and an upper transverse guide-block-support 55 having its ends rigidly connected with the bars 5% respectively.

A guide block 56 is mounted to oscillate in the upper guide support 55,

A similar guide-block-support 57 (Fig. 9) is rigidly connected with the lower rail of the tamper frame. A guide block 58 is mounted to oscillate in the lower guideblock-support 57.

The tubular tamper bar 59 slides the guide blocks 56 and 58.

A plate 60 rigidly connected with the freely in angle bars guide the movement of the plate and the tamper bar with which it is connected. Inside of the tamper bar is a coiled spring (Fig. 10) which has one end connected with the the downward in the guides.

A plurality of wipers are secured on each wiper shaft. There is one wiper for each tamper bar. Each wiper comprises a hub 62 and a plurality of radial arms 63. TV hen the wiper shaft is rotated the arms 63 will successively engage on the underside of the plate 60 with which it coiiperates, to move it upward to cause upward sliding of the tamper bar, and each time that a radial arm lifts the plate and passes it, the spring 65 in the tamper bar will act to slide the tamper bar quickly downward.

0 reduce friction and avoid unnecessary wear on the plate 60 each radial arm has at its outer end a little roller 63 contacting with the lower surface of the plate.

It is obvious that at each rotation of a three-arm wiper, the tamper bar will be lifted and dropped three times. I prefer to use three radial arms for each wiper but a greater or less number of arms may be used.

Shoes 64: are secured'at the lower ends of the tamper bars respectively. The shoes of the tamper bars adjacent to each side of the rails have a part cut away so that when the tamper bars are inclined under the rails as indicated by dotted lines in Fig. 3, the tamper bars may be raised without the shoes catching on the base of the rails. The means for inclining the tamper bars under the rails is a feature of great practical value, because it is important that the ballast shall be well compacted immediately below the rails and the construction disclosed is particularly effective for that purpose.

The means for raising or lowering the tamper frames and varying the inclination of the tampers relative to the ties, and the means for effecting the inclination of the tampers with respect to .the rails will now be described.

Parallel bars 66 and 66' with the lower rail of the tamper frame by pivots 67 and 67 respectively. A handle are connected bar 68 has its ends pivotally connected with the upper ends of the bars 66 and 66 re spectively. Connecting ally connected with the spective guide blocks 56 tampers on one side of bar. Similar connecting rods 69' are pivotally connected with the bar 66 and the respective guide blocks 56 of the first pair of tampers on the other side of the central tamper bar, as clearly shown in Fig. 6. If the handle bar 68 be s ifted to the left the connecting rods 69 and 69 will cause the tampers of both pairs to swing to the right and if the handle bar 68 be shifted to the right (Fig. 3) the connecting rods 69 and 69 will cause the tampers of both pairs to swing to the left.

The handle bar 68 may also be used to cause the tamper frame to turn 011 the wiper shaft, to vary the inclination of the tamper bars with respect to the ties, as indicated by dotted lines in Fig. 2.

Five tampers, that is to say, the central tamper and a pair of tampers on each side thereof are effective to operate between the rails, these tampers all swing in unison to the right or left as the case may be and all operate in unison.

An intermediate bar 70 (Fig. 6) has its ends pivotally connected with the bars 66 and 66 respectively.

Fixed projecting pins 71, one on each side of the guide block 56 of the central tamper bar 59, engage the block to cause the upper end of the central cradle to swing to the left when the bar 70 is shifted to the left and reversely to cause the upper end of the central cradle to swing to the right when the bar is shifted to the right.

A lever 72 is connected with the lower rail of the tamper frame by a pivot 73.

The pair of tamper bars 59 which operate outside of the left-hand rail are connected by a bar 74 having its ends pivotally connected with the guide blocks 56 respectively, and the pair of tampers which operate on the outside of the right-hand rail are connected by a bar 7a which has its ends pivotally connected with the guide blocks 56 of that air.

p A connecting rod 7 5 connects the lever 72 with the bar 7a and a similar connecting rod 7 5' connects the lever 72 with the bar 74.

If the upper end of the lever 72 be moved to the left the lower part of the left-hand pair of tampers will be caused to incline toward the left-hand rail and if the upper end of the lever be moved to the right the pair of tampers on the outside of the righthand rail will be caused to incline toward the right-hand rail.

At the beginning of the operation of tamping the ballast under the ties, the tampers must descend a greater distance than rods 69 are pivotbar 66 and the re of the first pair of the central tamper when operating nearthe-top of the ties. It

. is therefore necessary to provide means to adjust the tamper frames to suit the condition of the work. The vertical adjustment of the tamper frame is effected by the levers 4 1 which raise or lower the lifter bars 42. If the tampers are to operate at the greatest depth, the levers 1 1 will be set with the dogs 15 in the lowest notch 416 and if the tampers are to operate at a less depth the levers will be raised as indicated by dotted lines in Fig. 2, and set so that the dogs will enter a higher notch. The lifter frames 42 may be raised a notch at a time until they reach the highest position.

Each tamper frame supports a plurality of tamper bars, the tamper bars on one frame constituting one set and the tamper bars on the other frame constituting another set. The sets of tamper bars may be operated separately or together. V The means controlling the operation of the sets of tamper bars and the means con trolling the propelling of the machine will now be described.

Horizontal levers 80, 83, and 86 (Fig. 1) are mounted to oscillate on fixed pivots 81, 84, and 87, respectively, and the inner ends of the levers respectively are connected with the upper ends of vertical levers 82, S5, and 88, (Figs. 4, 11, and 12), mounted to oscillate on suitable stationary supports and having at their lower ends forks fitting in the grooves around the clutch- members 24, 23 and 19 respectively. If the outer end of the lever be moved to the right, the clutch-member 24L will be caused to slide to the left into engagement with the clutchmember 28 to cause the wheel 27 to rotate and drive the shaft 16, to cause the wheel 36 to drive the wheel 37 to propel the car, and reverse movement of the outer end of the lever will disengage the clutch-members and'cause the car to stop.

If the outer end of the lever 83 be moved to the left, the lever will cause the clutchmember 23 to slide on the shaft 14 into engagement with the clutch-member 26 of the wheel 25 to cause the wheel to rotate and actuate the right-hand set of tampers.

The moving of the outer end of the lever 86 to the right will cause the clutch-member 19 to slide into engagement with the clutchmember 21 of the wheel 20 to cause thewheel to rotate to actuate the left-hand set of tampers. 7

When both sets of tampers are in use, two operators, one at each end of the machine will control the operation of the machine. The operators will use the handle bar 68 to control the inclination of the tamper bars relative to the ties; and will use the levers 72 and the handle bars 68 to control the in clination of the tamper bars relative to the rails; and will use the levers 4 1 to raise or lower the lifter bars to vary the depth of operation of the tampers, or to raise them entirely above'the track when it'is desired to propel the machine on the track.
