the positions of the shoe and head when the rack is retracted being indicated by dotted lines. The stroke of the rack is limited by the slot l4, see Fig. 2, in which the shoe l5, attached to the rack, moves. Usually the stroke of the rack is about equal to a little more than half of the length of the rack.

Fig. .3 shows the start of the first step in shifting the track. The jack is set inan inclined position with the shoe 15 against the abutment I and .the foot of the-jack on the ground. The lever I8 is then operated to extend the jack until the rack has completed its stroke, thus shifting the track to the position it occupies in Fig. 4. In this movement of the track, the dirt that has been dumped at the side of the track is pushed along by the ends of the ties and by the rail itself, the jacking pressure serving to move the tiesin the general direction of their length or at a suitable angle to the horizontal where it is desired to surface the track;that is eliminate the dips and rises at the same time the track is shifted and by the same'operation elevate the rail to which the jacking pressure is applied. Setting the jack in an oblique position imparts to the track a tilting lift to allow the material of the fill to flow under the ties and thus'compensate for subsequentsettling of the material so that the desired elevation of the track may be secured and eliminating the need for subsequently'tamping material under the ties or subsequently surfacing the track.

The length of the extension 3 of the fixture A--B ismade such'that having shifted the track to the position shown in Fig. 4, retraction of the rack will bring its head far enough back to permit the head to drop behind the head 20 of the rail, the foot of the jack remaining where it was when the first shift of the track was effected. Then by again operating the lever I8 the track can be shifted asecond stage Only one or two jacks arerequired 'fo r'the track shifting operation for shifting an entire line of track. Preferably two jacks are employed simultaneously, spaced apart a distance of ten to twenty feet along the rail being jacked. Obviously this is a simple operation and is effected with very little labor. Not only isit unnecessary to find a new 'footing for the jack, but the labor of fixing the jack up and resetting itis eliminated, and the ground under the'jack having been compacted by the first shift will not compress much further during the second'shift. After compression of the second shift, retraction of therack brings the head l1 back far enough so that it can drop behind the abutment I so that the jack, with the same footing, can be used to shift the track a third step.

It will be. noticed that each successive shift of the track is made with the jack less inclined so that the track tilting effect becomesless with each shift. e

In carrying out the method it is preferred that only enough'material be dumped at the side of the track so that with but three shifts with a common jack base setting the track can catch up with the fill, and the ends'of the ties will then be adjacent the edgev of the fill. More material is then dumped at the side of the track and the fill builtup and the as before.

track shifted onto the new-fill Referring to'Fig. 1 it will be noted thatthe part B of the fixture'-A-B carries a plate I I. This plate H is of suflicient size to almost reachthe distance between adjacent ties, and serves to push material from between the ties at the jack location as the track is shifted, maintaining this space between the ties more or less unobstructed and pushing the dirt ahead of it as the track is shifted so that the jack-can be set for shifting without digging a hole for it. Furthermore with a fixture A-.B at the location of each tie space along the length of the track the entire track can be kept substantially on top ofthe fill and the shifting made easier.

As the rails may not be always shaped like the rail shown, the abutment for the jack head I! may be provided on the part A, which as shown is provided with a flange or lug 4 extending substantially horizontally from the vertical member 5. This flange can thus be used for an abutment in lieu of the rail head 28, and in moving the track the jack may be set so that in the first shift the shoe l5 of the jack bears on the abutment i, and in the second shift the head ll of the jack may bear against the second abutment 4. In the third shift the head l'i may bear on the abutment l. The distance between the abutments I and 4. or between the abutment 'l and the track, is'preferably a little less than the stroke of the rack so that after the rack has been shifted one stroke and the rack has been lowered there will be a clearance between the head H of the rack and the abutment i. This clearance is provided since the track may spring back slightly. after. the rack is tripped at the end of a movement, and tofacilitate the dropping of the head I! behind the abutment 4 after the first shift. In practice about an inch or possibly two inches of clearance may be provided for. That is, the distance from the abutment l to the abutment 4 may be one or two inches less than the stroke of the rack. I

Where the rail is used as the second abutment for the jack, the fixture A may be dispensed with, this part being illustrated in the drawings although it is not always necessary to use it.

While the method herein described, and the form of apparatus for carrying this method into efiect, constitute preferredembodimentsof the tending laterally with reference to said rail, the

end of said extension serving as an abutment against which the shoe is adapted to bear, the

distance from said abutment to the rail being such that, with a single setting of the foot'of'the jack, when the rack has been extended to its limit with the shoe bearing on said abutment, retraction of the rack will bring it into such position, longitudinally, that its head can-engage the rail, to the .end that a secondextenjsion of the rack will move the tracka second stage. j
