RAILVJAY-TRACK-TIE-REVOVING DEVICE.

Application led September 12, 1924.

My invention relates to improvements in railway track tie removing devices, and the object of the invention is to devise simple means whereby a railway tie may be quickly removed from beneath the track rails with out having first to remove the ballast from between the ties and thereby perform the operation in a minimum space of time and with a minimum amount of labour, and it consists essentially of the arrangement and construction of parts hereinafter more particularly described. i

Fis. 1 is a face elevation of my device showing the tie upon which it operates in transverse section.

Fig. 2 is a vertical sect-ion through the centre of Figure 1 on line 2 2.

Fig. 3 is a plan section on line 3-3 Figure Fig. ure 1.

Fig. is an enlarged detail view of the means for locking my travelling nut on the main operating threaded spindle of my de-` 4 is a plan section on line 4 4 Figvice.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates one of the rails of a railway track and 2 a portion of the tie which isl to be removed shown extending beneath the rail and on which the rail is supported.

8 and 4 are members of a saw supporting frame. rlfhe frame member 3 comprises the bar 5 and carrying at each end a bearing standard 6, inclined outward and in which are mounted a shaft 8 carrying sprocket wheels 77, and the pillars 9 and 10 formed integral with the bar 5. `11 is a threaded aperture formed at the upper end of each pillar 9 and 10. The pillars 9 and 10 are rectangular in plan section. The frame member 4 comprises a horizontal bar supported upon the upper ends of the pillars 9 and 10 and provided with bosses 19 having internally threaded orifices 2() in a line with the orifices 11 and through which and the orilices 11 extend securing screws 21.

lThe bar extends outward from the pillars 9 and 10 and upon such outwardly extended ends are supported inverted U-shaped standard members 12, the side arms of which are Serial No. 737,430.

79 is an endless chain which is supportedy on the sprocket gears 77 and 78 so as to assume rectangular form, the lower horizontal portion extendingV transversely of the tie 2 between the guiding flanges 28 and 24, and the vertical portion extending up through the slotted ends of the member 4.

80 are saw teeth sectionsV which are carried upon each of the links of the chain 79 and as they are carried transversely of the tie serve to cut the same when gradually lowered into contact therewith by means which will hereinafter be described.

I will iirst describe the means by which the chain 79 is manually driven.

46 is a standard frame mounted upon the frame member 4 in proximity to each end thereof and forming at its upper end a bear- 1 ing support for a crank shaft 47 provided with a crank 48 which is manually operated.

49 is a sprocket wheel secured to the shaft 47 and 50 is a sprocket chain connecting the shaft 49 with a sprocket wheel 42 secured to.

a shaft 40 journaled in standards 39 carried by the frame member 4. 41 is a sprocket also secured to the shaft 40. 44 is a sprocket wheel secured to one of the shafts 14; 45 is a sprocket chain connecting the gears 41 and 44. It will thus be seen that the chain 79 is driven from the crank 48 which is manually turned, the drive passing from the shaft 47 through the gear 49, chain 50, sprocket 42, shaft 40, sprocket 41, chain 45 and sprocket 44 to one of the shafts 14 and the gear 78 secured thereto which carries and drives the.

leave an intervening space 3l at each side,

of thepillar and allow of the sleeve* portion passing through the openings 29X and 310x in the member 4 so that such member as it moves downward` can m-aci; with the member 25. i

The bar member is secured"to` the' rail' 1 by means Which I Will now describe.

members 62. The outer end of the bar 78 extends through a slot 7 5 in the standard member 75X. The lower edge of the bar 73 is provided with a series of notches as indicated at 76 and thefouter end of the bar with a knob 771 by which the bar may be operated.

. It will be readily seen that by lifting the knobbed end of` the bar 73 upward the notches 7 6 disengage with the lower end of the slot 7 5 and the bar drawn longitudinally to carry the gear 70 from one face gear 5l, 52 and 53 to another to regulate the driving speed.

60 is a worm formed on the shaft 59 and meshing with the worm gear 34 secured to the shaft 32.

It will thus be seen that the shaft 32 driven from the gear 42 driven from the crank 48 -as hereinbefore described and through the face gears 51, 52 or 53, gear 70, shaft 59, worm 60 and worm gear 34.

l will now describe the mechanism by which the bar forming part of the frame member 3 is carried downward by the rotation of the shaft 32 to feed the lower horizontally extending portion of the saw into engagement with the tie to cut the same as the saw is revolved as hereinbefore described.

8l and 82 are the members of a divided nut which are pivoted at 83 and 84 tothe member 25, the free ends being forced apart by the spring 85.

In order to hold the members 81 and 82 of the nut in engagement with the thread of the shaft 32 the members 8l and 82 are provided with outwardly extending portions 86 and 87 passing through a slot 88x formed in the housing 88.

rllhe housing 88 is carried by the member 25 and in which is sllidably mounted the movable locking member 89 provided with -vertical bores 90.

91 is the base plate of the housing 88 by which it is secured to the member 25. 92 are projections extending from the housing over the upper ends of the bores 90. rThe wall of each of the bores 90 is provided at its upper end with a vertical slot 93 in which the projections 92 have movement.

94 is a notch in the lower edge of the lock* ing member 89 provided preferably with an outwardly flaring edge 95 and into which notch the arms 86 and 87 fit so as to hold the members 81 and 82 of the nut together and in engagement with the thread of the shaft 32 against the pressure of the spring 85.

96 is a handle by which themember 8G may be raised or lowered.

It will be understood that the parts and 114 are the stationary parts of the device, all the remaining parts being movable, that is, the parts 9, 19, 4 and 5 form a rectangular frame which is movable vertically,

the parts 9 and 10 sliding in the sleeves 28 by the operation of the crank 48 and the parts driven thereby. As the shaft 32 is turned so as to screw downward through the nut members 81 and 82, the frame comi prising the members 9, 10, 4 and 5 being f supported thereby at 32X drops downward by gravity, the relative position of the shaft 32 to the member 4, 5, 9 and l() remains unaltered. The saw teeth 80, and sprocket chain on which the teeth are mounted being carried downward with the frame are driven against the tie by the weight of the frame exerting a constant pressure as the saw revolves and the cutis made. During this operation the. arms and 36 pass through the slots 27.

1When the cut is completed the locking member 89 is raised by the handle 96 so as to release the portions 86 and 87 of the nut. The nut then springs open away from the shaft 32 permitting the frame members 3 and 4 and the parts carried thereby to be raised manually to their normal position.

As the frame is raised the arms 35 and 8G pass at each side of the open nut and as these members of the nut engage the converging arms 36 the nut members are forced inward to their closed position holding them in such position, the locking member being then forced down by the spring 90X so that the notch 94 again straddles the portion 86 and 87.

The bar 5 which is inverted channel shaped is provided with cross spindles 37 on which are mounted a roller 38 against which the lower horizontal portion of the chain 7 9 bears to reduce the friction as the chain passes horizontally under the pressure of its supporting frame.
