JUMBO roe TUNNEL renne.
Application filed June 2,1926. Serial N-.IrlIISQSO-bif i i This invention relates tothe tunneling art; and particularly to a device for manipulating the sectional meta-l forms used in tunnels when the san-1e are to be lined with concrete, as is now very frequently done.
The principal object ofy my invention is to provide a jumbo to be4 used. in connection with' a collapsibley or jointed section-al vform toL engage, support and-transport the section when it is desired toI shift thesame; and so constructed that the services of only a; single man, or at the` most two men, are necessary tov operate the jumbo even When thel latter is supporting a large and heavy form section.
With lthis jumbo, in connection with the simple jointed form-section used, it is pos-4 sible to advance the forms or sections as required with greatspeed and small loss of time, enabling' lining operations to be carried out at a minimum of cost and in very quick time. i
A further object of the invention is to produce' a simple and inexpensive device and yet one Which Will be exceedingly effective for the purpose forwhich it is designed.
These objects I accomplish by means of such` structure and. relative arrangement of parts as. Will fully appear by a perusal lof the following specification' and claims.
' In the drawings similar characters of reference. indicate corresponding parts in the Several' views: Y l Y VF ig. l. is a side elevation of my improved jumbo shown in connection with a fragmen-l tary' portion ofi sectional. form.
Referring now more particularlyv to the characters ofreference. sho-Wn on the drawng's, the forms' used in connection with my jumbo"v are substantially of horseshoe shape in cross section. The form consists of a number' of sections to be longitudinally alined with each' other, eachA section comprising transverse top frames 1 spaced apart longitudinally, and side. frames 2' depending; from the top frames to form a continuous outline of the desired shape. The frames 1 are i hinged? to the frames Z, so that the l'a'tter can swing inwardly from their normal position, b longitudinal rods 3 Which extend through all the frames l and 2. Plates l are secured to and connect the various frames l and 2 on the outside of the same to form a solidk continuous covering. Sald plates of course are separated longitudinally along the hinge lines of they members 1 and 2.'
Horizontal 'fiat bars 2a extend between the members 2- along the bottoms thereof. In setting a section up in the tunnel', mud sills 5 areA setalong the bottoni of the' tunnel,V the bars/l resting tlrereon.- These' bars are tiemporarifliy spiked to the sills. Wedges 6 are then pla-ced. under'. thel sills at intervals sov that each form-'section may be supported in exact allinement with adjacent sections.` The end frames l anda of each seetion'are provided with a series oit' holes 7, soi that bolts may be removably placed through the abutted' framesv of adjacent sections tov temporarily fas-ten the same together.k
My improved j-umho to be used in supporting and' transporting a section alongv the tunnel as lin-ingV operations proceed, comprises a main `hed or frame (Si, built up of suitable material and lin af rigid manner. Said Vfria-me is supported by longitudinally spaced Wheels 9- whichl ride on rails 10 laid on ties l1 Which rest on the' bed o'the tunnel.
Supported by a-ndt projecting upwardly from the frame 8 are longitudinal-1y spaced toggle-joint structures'. Each such structure comprises lower' arm members l2" and upper arm members 18",1A arranged as transversely sepai-"ate'd pairs suitably braced together to form rigid units. The lower' armunits are pivoted in common onto the iframe 8 as at 14:# andv diverge longitudinally of the jumbo t'ovv'ard their upperends. VTheupper arm units are pivoted: common with fthe'u-pper ends of the arms l2 and converge toward theirupper ends'. At' said upper ends the arms 13 are pivoted in common as at lonto a horizontal frameI which includes longitudinally extendingbea 16; lhese'A beams at their ends and close to the pivots l5I support transverse overhanging beamsfl?, the
latter vbein-g3 preferably reinforced vertically byv gusset plates 181. The upper ends-of the loWerarm units and thef lovver ends o'lthe ,100 'upper armunitsare pivotally connected together 'by'nieans of transverse blocks' 19 er'- tending. rvbetween corresponding pairs of arms, the blocks having lateral trunni'ons- 20,
VWhich form pivotal pins aswell as" connect!v ing means for said arms;
A longitudinal shaftv21 extends through all the blocks, with crank handles 22 at its V ends. Y This shaft is threaded through the blocks, the threading for the blocksk of each proper height and Ysaid beams to clear the section.
toggle joint structure being right and left hand. Therefore when the shaft is turned one way or the other, the arms of the toggle joints will approach or move away from each other attheir pivotal connections 20, causing the upperends of the arms 13 and the frame 16 to be raised or lowered accordingly. Since both toggle joints are identical in size, and they are connected in common by the single operating saft 21, both structures will move to the same extent and the vertical movement of the frame 16 will be uniform at both ends, and parallel to a horizontal plane. Y
lnoperation the frame 16 isy first lowered by manipulation of the shaft 21 so that the outer ends of the beams 17 clear the form frame members, allowing the jumbo to be moved longitudinallythrough the tunnel without interfering withthe form sections. lVhen the jumbol has arrived atfand under the section toA be shifted, the frame 16 .is raised so that the beams 17 rest'on the longitudinal rods 3 of theforin. The spacing of the beams 17, and the position of the jumbo relative to the form, is such that the engage* ment of said beams with' the rods 3 will be at points close to certainoones of the form frames, iso as to prevent, deflection of the rods. The rods are then held against lateral slipping on the beams v17 by hooks 23 mounted on said beams and arranged to cetachably engage said rods.
Assuming that the bolts that fasten adj acent form sections to each other have been removed, as vwell as the spikes holding the bars 2a tothe mudV sills; theshaft 21 is then rotated to further raise the frame 16, causing the beams 1'( to rest firmly against rods 3..- Then upon releasing the wedges 6, the mud sills 5 may be lowered sufficiently to enable the frames 2 to swing inwardly. 'The form supporting elements of the jumbo are thenlowered until the upper fornr frame 1 is entirely clear ofthe frame of an adjacent form section, as shown in dotted v lines in Fig. 2.
The ported therein, is then moved. along the tunnel inwardly of the other form sections until it has arrived at the location where said section is again to be set up. rlhe form supporting elements of the jumboV are then again raised to place the section at the I so that the frames 2 can be swung outwardly to overhang the sills. The form is then lowered until said frames 2 rest on the sills, when the beams 17 ofthe jumbo may be lowered still further to cause The final 'umbo with the form section sup-V neanase lining up of the form section relative to an adjacent section is then done by manipula- Y tion of the wedges 6. Owing to the use of the toggle arm and screw structure, a very powerful appliance is provided, which may be. easily manipulated by one or at the most two men operating the handles 22. Y
From the foregoing description it will be readily seen that I' have produced such a device as substantially fulfills the objects of the invention as set forth herein. i
While this specification sets forth inxdetail the presentand preferred construction of the device, still in practice such deviations from such detail may be resorted to as Vdo not form a departure from the spirit of the invention, as defined by the appended claims.
Having thus described my invention what l claim as new and useful and desire tosecure by Letters Patent is: o
1. ln combination, a tunnel form-section including transverse topY frames, side frames depending therefrom and longitudinally eXf tending rods pivotally connecting the side and top frames; a wheel supported frame movable along the tunnel underthe top frame and inwardly'of the side frames, and vertically movable means on said movable frame for detachably engaging said rods to cause the weight'of the form-section to be supported by said means.
2. in combination, a tunnel-form section including transversely extending top frames,
and longitudinally extending rods adjacent the ends of said frames; and a jumbo for manipulating the form including a wheel supported frame movable under the form., raising and lowering meansk on said wheel frame, and transversely extending beams carried by said means for direct but detachable supporting engagement .with the rod members.
3. A structure asin claim 2, with catch means mounted on the beams for detachable engagement with ,the rods to prevent lateral movement of the rods and form relative to the jumbo.
4. ln combination, a ltunnel-form section including transversely extending top frames,
a jumbo for manipulating theV form including transverse beams Vdisposed under the form, and meansfor raising and lowering the beams; and members mounted in vcormection with the form frames at the sides thereof positioned to detachably rest directly on the beams adjacent their ends when said beams are raised.- i j ln testimony whereof l affix my signature.
