-Referring indetail to the drawings; and-for the present tojFigs; 1 to 2; a form section [0" comprises an" arch or crown member II" and an invert member or portion I2. The arch member is -hin'ged' at l-3 andl4, so it can be collapsed forFpassa-ge through a similar section,"as' will be describedi'n detail later. The portions'of the 5 form section are composed of spaced circflinferenti'al'ribs I5 connected by longitudinal reinforcing angles l6 and sheath'ing' plates" |1.

The overhanging ends of the beams 26- are provided with hangers 4| on which rolls 42 are journaled. Trolley beams 43 are movable on the rolls 42. Hold-down. rolls 44 are journaled in the flanges of the hangers 4|. The beams 43 are provided with trolley hoists 45. A single central trolley beam may be used if desired, instead of the two side beams, as shown in Fig. 2a.

Contractible ratchet members 46 are secured to the ends of the beams 21 and to channels 41 on the side portions of the arch member.

The manner of using the structure described above will now be explained with reference to Figs. 3 through 10.

As indicated in Fig. 3, it is usual to employ two

arch members

48 and 49, and three invert

members

50, and 52. Fig. 3 shows the position of the traveler and the trolley beams when the concrete has been poured around the arch member 49 and the invert member 52 disposed adjacent the heading 53. This concrete for the invert or bottom portion of the lining may be poured from cars 54 (see Figs. 2 and which travel along a track connected with the rails 31, and up an incline 55 to the deck 28. The concrete for the upper portion is usually placed through pipes by pneumatic pressure or by pumping. During the pouring operation, the traveler is secured to the arch member of the form by bolts 56 connecting the flanges of the beams 24 to angles 51 welded to the ribs l5. When the pouring of concrete has been completed, the incline 55 is taken down, the bolts 56 removed, and the traveler moved away from the heading by the length of one form section (conveniently about 18 feet) to about the position indicated in Fig. 4. When the traveler has been withdrawn, the heading is advanced by mucking in the usual manner. To facilitate this operation, each invert member is provided with a switch (not shown) whereby cars 58 may 31 in the foremost lining section. In this way, an empty car coming through the tunnel may be placed on one side of the foremost invert section, by properly manipulating the switch, so that a full car on hauled out while the first car is being filled. The switches on the invert sections are such as to permit them to pass a car along the center rails of the invert sections behind that adjacent the heading.

After the heading has been sufficiently advanced, it is necessary to move an invert and arch member forward to constitute anadditional lining section. Fig. 5 illustrates this operation. The first step is to move the trolley beams rearwardly, secure the invert member 58 to the hoists 45 therefor, and lift it. The jacks 39 are then positioned and extended sufficiently to support the traveler on the arch member 48. The feet 29 are then raised, as indicated in Fig. 6 and at the left-hand side of Fig. 2, whereupon it is possible to advance the hoists 45 and move the invert member 5!! forward under the traveler to a position as indicated in Fig. 7. The feet 29 are raised by manipulating the ratchets 33.; In addition to supporting the traveler on the

jacks

39, 51 by the bolts 56.

The next operationis the collapsing of the arch member 48. to lower the feet 29 so The first step in this operation is that the wheels 34 again 75 rest on the rails 35, as shown in Fig. 7. The jacks be diverted to either pair of rails 35,

the other pair of rails can be The angles 51 remain secured to the beams 24 or, if not previously attached, are bolted thereto. The ratchet members 46 are then operated to pull the side portions of the arch member inwardly about their hinges l3 and 14. It will be understood that the concrete surrounding the arch member 48 and the invert member 5| has matured sufficiently to permit removal of the former. The ratchets 33 are then operated to permit the feet 29 to be retracted into the legs 23. Since the traveler is not supported independently of the wheels, it is lowered so that the top of the arch member 48 clears the inner flanges of the ribs in the arch member 49. This lowering of the carriage also lowers the trolley beams, but the hoists 45 can be taken up to maintain clearance between the invert forms 59 and 52.

The next step is to advance the traveler to the position shown in Fig. 8. When in that position, the invert form 59 is lowered into place, the rear edge being secured to invert form 52, and the forward edge being supported on a'bulkhead 59. Intermediate supports can be placed under the invert member 58, if desired, to sustain the weight of the traveler which is next advanced, as shown 39 are then released.

' in Fig. 9, after withdrawing the trolley beams.

, ticular advantages of the construction described is the fact that it is not necessary'to move the traveler any further ahead than the arch member being-placed. A further advantage is that it is unnecessary to lay rail on the previously completely section to permit advancement of the form. It is necessary, of course, to lay rail to replace that on' the invert memberwhich is moved forward, but it is not necessary that this be completed before such forward movement can be effected. There is thus no delay, as the additional rail on'the floor of the completed portion of the lining can be laid while the forms are being placed at the edge of the section last poured. A further advantage is that the invert section is not hinged. This permits it to be made rigid enough to safely support the traveler and form during forward movement without additional intermediate supports.

Although I have illustrated and described but a preferred embodiment of the invention, it will be understood that changes in the construction and mode of operation may be made without departing from the spirit of the invention or the scope of the appended claims.
