bars 12' vand 14 are-carricd` by screws 26 guided in uprights which are mounted upon truck frames 32, one located at each side of the main track rails 10. Each of the two outer truck frames 32 is supported upon This clutch jaw 62 is movable into and out a suitable set of wheels or rollers 3-1 movable along supplemental track rails-"3G provided for the purpose, as shown, parallel to the main track rails l0. By the use of these supplemental track rails the bars 12-and 14 may, whenever lifted'high enough to clear the rails 10, be moved longitudinally of said track rails 10 so as tojlongitudinally adjust the lifting bars to proper application to the locomotive body 38, one of whose many possible forms is suggested in dotted--lines in the upper portion of Fig. 2.
The trucks and lifting devices may, if desired, be made exactly as shown," described and claimed in the patent application of Fred A. Bundle for screw jack locomotive hoists, Serial Number 665,682, filed December l1, 1911, wherein means is provided for selectively applying power for operating the lifting mechanism or moving the truck by power along their respective tracks. ln the device here shown in the drawings, the trucks 32 are movable along their respective tracks 3G by the use of levers 40 operating ratchet devices 42 carried `by the shaft 46. Any method of moving the trucks along these tracks maybe used without departing from this invention.
Mounted in any sort of suitable bearing 48 on opposite sides of the track 10 are two parallel rotatable .shafts 50 driven by any suitable source ofpower -at equal speeds. In the particular case here illustrated these shafts are driven by a. motor 52 which operates them through the two sets of bevel gearing 53 and connected together bythe shaft 55 which is located 'below the rails 10 so as to be out of the way of a passing loconotive.
At the base of eachone of thevertical screws 2G is a worm wheel 56 rigidly connected to the screw 26 by any suitable means and meshing with aworm 58, journaled upon the adjacent shaft 50, and carrying at its end any suitable clutch jaw G0.j Meshable with this jaw is a clutch member 62 sl idably but non-rotatabl y mounted upon the shaft 50 by any of the. well known methods.
of mesh with jaw bythe operation of a h and lever (5l pivoted upon any suitable support, as for instance 6G, a: :l carrying a pin (3S which' enters an annular notch 70 in the aw G2 so that moving the lever Git will move the clutch jaw back and forth along the shaft without interfering with the rotation of the clutch men'iber by the shaft.
From the description, of theA foregoing parts, which are all well known in the art, it is obvious that the operator may, by operatlifting position for ing a particular lever 64 to throw its. particular `clutch jaw G2 into or out of'mesh with the jaw G0, as the case may be, stop or start the rotation o f the particularscrew 26 whichfis in" operation with that particular clutch jaw (30 with which the'operator is working.` 'As `all six of the lifting screws 26 Vare provided with the mechanism just described,` it is obvious that by having two operators, one on each side of the track, manipulate the levers 64 of a particular lifting bar, as for instance 12, the bar and the load upon it may be moved-.up and down` at the will of the operator independently of the other bars 13 and 14:. It is also obvious that by having an operator at each of thev six levers 64 simultaneously and correspondingly operate said six levers', all three of the bars 12, 13 and 14 may be simultaneously moved inueit-her direction depending upon the rotation of shafts 50, or b rought to rest as the commanding workman may direct.v
The same result may also'be secured by having and shaft, then throw in all the clutches one after the other and the-n start the motor again in the desired direction.
In order to do away with objectionable springing in the end portions of the shafts 50 adjacent to the trucks 32, a supplemental support 7 2 mounted upon Wheels 74 movable along the adjacent tracks 86 is provided.-
single operator first stop' the motorA The particular shaft section 50 to which.
these devices are applied rotates freely in the upper portion of the support 72 and the support may be moved along the track 36 to a position where it is .midway between the adjacent truck 32 and the next adjacent stationary support 48. l y K Thetrucks 32 and supports 72 may be connected by chains, rods or links as suggested in the upper left handcorner of Fig. 1 so .that they move `more or less in unison as desired; j
It will be noticed that the middle lifting bar 1 3 is carried from a stationary support. thereby doing away with the expense 'of trucks at opposite ends of the bar and what is more important, tending to steady the entire mechanism during the operation of-raising a ,locomotive thus preventing longitudinal movementjof the locomotive and. any of the lifting parts after the lifting operation has actually begun.
In the operation of the entire device, the various lifting bars are moved in the man'- ner described either'independently or simultracks 10. The locomotive to be lifted is now moved along the track rails 10 until its central body portion 38 is directly over the central lifting bar 13. The operators now independently o r in combination raise each of the liftingbars 12 and 14 so that they are above and clear of the track rails 10 but are not yet high enough to Contact with the end body port-ions 38 of the locomotive. They then by use of ratchet levers 40 move theV lifting bars 12 and 14, which are up to this time outside the ends of the locomotive, along the tracks to positions where the respective bars register with suitable body portions of the locomotive `to bc lifted. The operators then 'either independently or simultaneously move these respective bars 12 and 14 upward until they are in lifting contact with their respective vbody portions of the locomotive. Then proper adjustment of the supports is made whereupon all of the levers 64 are thrown to 4lifting position land as the" different sections of the shafts 5,0 rotate simultaneously all parts of the locomotive are simultaneously lifted at'the same rate of speed, thereby reducing the st-rain upon it to the lowest point. vWhen the loco 4motive has reached the proper position the motor 52 is stopped thereby sustaining the locomotive in lthat position and the wheels may be rolled away. When it is desired to lower the locomotive, motor 52, is operated in the reverse direction unt-il the locomotive rests upon the rails 10, whereupon the manipulations heretofore described are re. versed to return the various liftingbars to their normal position with their-rail sections 18- in register with the adjacent portions of the track whereupon the locomotive may move along the track rails 10 off from and clear of the parts which have been heretoi foredescribed. The trucks on which the locomotive is thus moved away may be its regular ones or only temporary ones.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 1# 1. lin a device of the class described the combination with a trackv for an object to be lifted, three lifting devicesalong the track, one located on stationary supports between the other two, the latter two being movable along'the tracks toward -or from the central lifting'A device, and means for then simultaneously operating all of the three lifting devices at the same rate of speed.
2. ln a device'of ,the class described, in, combination with a tirack for-an object to be lifted, a lifting ,device mounted upon a stationary support near the center of a length of the track, two other lift-ing devices on opposite sides of the first lifting device and near the end of said track length movable toward and from the central lifting device, and a power shaft adapted to then simultaneously operate all of said lifting devices 'at the same rate of speed.
In a device of the class described,a' portion of track on which an object to be lifted may rest, a lifting bar'near the center of said track vertically operable to lift the center of the objecttto be lifted and carried upon stationary fixed supports outside the track, two otherlliftingbars, one near each end of said track operable to lift the respective ends of the object upon saidtrack carried upon truck devices outside the track movable parallel tosaid track to adjust the position of said end lifting bars with reference to the length of the object which is to -be lifted, and power means adapted, when/the various lifting bars have been adjusted longitudinally of the track to simultaneously and correspondingly loperate all three lifting bars, for the purposes set forth.
f 4. In combination with a pair of track rails, a' lifting bar extending across said rails .and movable vertically through openings in said rails froma position below to a position above said rails and vice versa, rail members carried by the bar adapted, when the bar is in one position, to close the spaces in said rails through which the bars move so as to permit the passage ofan object to be lifted by said' bar along said rails, means for lifting said bar located along said bar outside the planes of said rails and means for trans- .lifted by said bar.along said rails, a truck supporting said lifting means movable when the bar is lifted abo-ve the rail longitudinally of said track rails, and` means loperable at will in any position of the truck for lifting said bar.
6. In a device of the class described, a portion cfa track on which an object to be lifted may rest, three lifting bars of greater length than the width of the track extending across the track in recesses which normally permit their lying below the track and clear of an object to 'bc lifted passing on sa-id track, rail devices carried by said lifting.. bars registering with openings in the track formed to permit the lifting bars moving from said normal position to a position wherein said bars are above and clear of the tracks and vthus in said normal posit-ion making the tracks contiiiuous, a support for the opposite ends of the central bar, a sup porting device for the opposite ends of cach 4, l massifs@ toward and from the central bur, lifting I I n witness whereof, I have hereunto subdevices for said bars earned by the respecscmbed my name in the presence of two W- tive supporting devices, and means operable messes.
