No. 308,973 9 Claims. (Cl. 214-515) This invention relates to :a transfer system and more particularly to a transfer system including a trailer suitable for transporting ya prefabricated building structure from a prefabrication site to a final assembly site, having at least one component thereof convertible into a track means for transferring the building structure from a selected location adjacent the foundation site onto the foundation site. This invention also contemplates a novel Imethod of transferring a structure from a given location toa selected location.

In the building construction industry it has been found that the construction costs of smaller buildings such as homes and the like `can be reduced considerably by precu-tting, pre-forming or prefabricating many of the component units at prefabrication sites, utilizing mass production techniques, and tran-sporting such uni-ts to job sites for final assembly. This practice in the industry further has progressed to the stage where entire homes are prefabricated and transported in sections to job sites for final assembly.

One of the most significant limitations in this relatively new practice has been in the transportation of the prefabricated building structures from the prefabrication site to the job site, which is usually by truck and trailer, land transferring the building structure from lthe trailer onto the foundation site, which usually is performed by means of a crane apparatus. Most of the trailers in the prior art have not been found to be entirely satisfactory for use in the transportation of such structures, in that they are not suliciently suitable to bear the weight of such structures under dynamic load conditions, to readily negotiate the varying course and grades of roadways and to avoid the development of stresses and strains in the Prefabricated structures during the transportation of such structures. In addition, with the use of such trailers, additional means always are required for transferring the struc-tures from the trailer onto the foundation site. The requirement for such a separate means for transferring the structures from the trailer onto the foundation of the structure `has been found t-o cause considerable delay and increase in cost in the construction of such structures.

Accordingly, it is the principal object of this invention to provide an improved `tranfe-r system.

Another object of this -invention is to provide an improved transfer system for transporting prefabricated building structures from a prefabrication site to a job site where such structures 'are to be finally assembled.

A further object o-f this invention is to provide an improved transfer system including a ltrailer for transporting prefabricated building structures from a prefabrication site to a selected location site where the structure is to be finally assembled, having at least a component there-of yconvertible to =a -track means for transferring 'the building structures from the trailer ont-o the foundation site.

A still further object of this invention is to provide an improved Itrailer for transporting a Prefabricated building structure from a prefabrication site to a selected site where such structure i-s to be finally assembled, having at least a component thereof convertible to a track means for transferring the structure from the trailer onto the foundation of the final building structure, which does not "ice require any additional apparatus for transferring the building structure from the trailer onto the foundation.

Another object of `this invention is to provide an improved trailer for transporting a prefabricated building structure which is suitable for supporting lsuch building structure under dynamic load conditions.

A further object of this invention is to provide an irnproved trailer for transporting building structures which is adapted to readily negotiate a varied course and grades in roadways.

A still further object Iof this invention is to provide an improved trailer for transporting a lbuilding structure from a prefabrication site t-o a final assembly site, having at least a component thereof convertible to a track means for transferring the building structure from a selected location adajacent a foundation site onto the foundation site, which is simple in construction and requires :a simple assembly operation.

Another object of this invention is to provide :an improved Itrail-er for transporting building structures of considerable size from prefabrication sites to selected sites where they may be finally assembled, which may be partially disassembled and converted into a track means transfer system for transferring the building structure from a selected location adjacent the foundation site onto the foundation site, and reassembled in an abbreviated form to facilitate transportation of the trailer back to the prefabrication site.

A further object of this invention is to provide an improved trailer for transporting prefabricated building structures having relatively few parts, and which is inexpensive to manufacture.

A still further object of the present invention is to provide a novel method of transferring a structure from a given location to a selected location.

Other objects and advantages of the present invention will become apparent to those persons skilled in the art, in the following description when taken in conjunction with the accompanying drawings, in which:

In accordance with the broad aspects of this invention there is provided a transfer system including a trailer for a prefabricated building structure generally comprising a wheeled unit, carrier means mounted on the wheeled unit for supporting the building structure on the axis of the trailer, which includes support means that can be detached from the trailer and positioned along a line of travel from a selected location adjacent a foundation site onto the foundation site for supporting the building structure for travel thereon to the foundation site and means for coupling the carrier means to a suitable prime mover means.

Referring to the drawings, there is illustrated a preferred embodiment of the present invention. Referring specifically to FIGURES l through 4, there is generally provided a wheeled unit 20, a `carrier frame 21 mounted on the wheeled unit, an elongated support frame 22 detachably secured to the front end of the carrier frame, and a coupling member 23 selectively detachably secured to the front end of vthe support frame 22 and the front end of the carrier frame 21, As shown in FIGURE 1, the carrier frame 21' and the support frame 22 are adapted to be attached to provide a bed for a Prefabricated building structure 24, having a plurality of transversely extending, longitudinally lspaced floor joists 25. In addition, it will be noted that the coupling member 23 is adapted to be coupled to a suitable prime mover means 26.

The rectangular frame member 26 also is provided with a pair of diagonally extending cross brace members 4S and 49. The end portions of the rear end member 30 and front end member 31 are provided with depending bracket members 50, each having a horizontal shelf portion 51 disposed rearwardly and forwardly thereof, respectively. Mounted on each of the shelf portions 51 of the depending bracket members -50 is a iiuid actuated device 52 having a piston member 53 rigidly secured to the shelf portion of the depending bracket 5t) and a cylinder member 54 rigidly secured to the carrier frame 21. The fluid actuated devices 52 each are provided with fluid lines 5S which are connected to a suitable source of fluid under pressure, having control means preferably located at the'controltstation of the prime mover means. It will be appreciated that the fluid actuated devices 52 can be'utilized to vertically displae the carrier frame 21 d relative to the wheeled unit 20, as illustrated by the broken lines 56 in FIGURE l.

The carrier frame 2.1 is substantially rectangular in shape, surrounding the frame 27 of the wheeled unit and adapted to lie in the same plane therewith. The carrier frame comprises a pair of side members 57 and 58 disposed exteriorly along

side members

28 and 29 of frame 27, which normally are supported on the upper surfaces of bracket members 32, a rear end member 59 spaced rearwar-dly from rear end member St) of frame member 27 to accommodate laterally spaced horizontal plate members 60 and 61 rigidly secured to the carrier frame and the cylinder members of the rearwardly disposed fluid actuated devices, and a front end member 62 spaced forwardly from front end member 31 of frame member 27 to accommodate laterally spaced horizontal plates 63 and 64 which are rigidly secured to the carrier frame and the cylinder members of the forwardly disposed fluid actuated devices 52. The rear end member 59 and the front endl member 62 of the carrier frame each are provided with` laterally movable Outrigger members 65, which can be extended laterally, as shown in FIGURE 2, to provide' lateral support for the lateral extremities of the building structure 24. Disposed on the forward end of the carrier frame are a pair of forwardly extending male members 66 and 67 disposed in alignment with side members 57 and 58 of the carrier frame, respectively.

The support frame member 22 comprises a pair of transversely spaced

support beams

68 and 69, transversely spaced support beam members 7 t) and 71 disposed in longitudinal alignment with

support beam members

68 and 69, respectively, and intermediate cross beam member 72 adapted to connect the forward ends of

support beam members

68 and 69. Additional cross beam members may be provided as desired. The frame member 22 is attached to the carrier frame l21 by means of the male members 66 and 67 which are received in the rearward ends of support beams 68 and 69, respectively, and rigidly secured by means of a plurality of bolts 75. As best shown in FIG-

URES

2, 5, 6 and 7, the

support beam members

68 and 69 are provided with forwardly extending male members 76 and 77, respectively, which are received in the rearward ends -of support beam members and 71, respectively. As best lshown in FIGURES 5 through 7, the male member 77 is preferably a box beam adapted to be received within the support beam member 71. The male member 77 is provided with a transverse member 7S, havi ing an inwardly tapered opening 79 and a transverse mem-- ber 80 having an inwardly tapered opening 8l. The sup porty beam member 69 is provided with openings registered with the tapered opening 79 for receiving a tapered bolt 82 having a threaded end portion 83 which is threaded into a suitable vthreaded opening in the end of cross beam member 72. The longitudinally aligned support beam member 71 also is provided with openings registered with the tapered opening 8-1 for receiving a tapered bolt 84 having a threaded end 85 therethrough for securing the support beam member '71 rigidly to the male member 77 by means of a nut 85 threadedly mounted on the bolt 81, tightened against a washer member 87 mounted on the end of the bolt. The male member '76 on the opposite side of the support frame is provided with a similar securing assembly, as described. Similarly, the front end portions of support beams 76 and 71 are provided with forwardly extending male members S8 and 89 Ywhich are adapted to be received within aligned members 23a and 2313 of the coupling member and secured thereto with the cross beam members 73 and 74 inthe vmanner describe-d. It will be appreciated that when the support frame member 22 is detached from the lcarrier frame and the cross beam members 73 and 74 are removed from the coupling member,

the coupling member can be attached to the carrier member so that the male members' 66 and 67 are received within 'and bolted to the female members 23a and 23b of the coupling member, as illustrated in the broken lines in FIGURE 2.

Referring, to FIGURES 1,v 8 and 9,` the building structure in the yposition as illustrated in FIGURE 1 is rigidly secured to the carrier frame and lthe support frame by means of a plurality of clamping members 90. As best seen in FIGURES 8 and 9, each ofthe clamping members consists of a horizontal portion 91 adapted to engage the bottom surface of a supportbeam, a vertical ilange portion 92l adapted lto engage the inner surface of the support beam, and a vertical plate portion 93 adapted to engage the 'outside surface of the support beam. An upwardly extending arm member 94 is rigidly mounted on the vertical plate portion 93, having a bearing block- 95 mounted thereon', which is adapted to engage a side of a floor joist 25. Also rigidly mounted on the vertical plate portion 93 is an upwardlyextending arm member having a clamp screw 97 mounted in a suitable opening therein for movement toward the bearing block 95. The clamp screw is provided with an enlarged end portion 98, which is adapted to engage the iloor joist on the opposite side from the bearing block to rigidly clamp the clamping member mounted on the support beam to the floor joist. It will be appreciated that the clamping members 90 are mounted on the vsupport beams in the manner as shown in FIGURE 8 and clamped to the floor joist to provide an integral structure between the carrier frame and support frame and the building structure. Accordingly,by clamping the entire carrier frame and support frame along the entire length ofthe building structure, the weight of the building structure is distributed evenly along. the entire length of the carrierV and support frames.

In the use of the present invention for transporting a building structure as illustrated in FIGURES 1, 10 and 1l, consisting of a one-half section of a home divided along a longitudinal centerline, the carrier frame, the support frame and the coupling member are assembled as illustrated in FIGURES 1 and 2, and the building structure is positioned on the frame members with the lloor joist 25 extending transversely relative to the longitudinal axis of the trailer. The building structure is then rigidly secured to the frame members by meansA of a plurality of the clamping members 90 Which are mounted on the under side of the support beams and clamped to the transverse floor joists. The trailer then is properly assembled with the building structure rigidly secured thereto for transporting the same over roadways to the particular job site. By rigidly securing the building structure along the entire length of the carrier and support frames, the weight of the build-ing structure is distributed along the length of the trailer so as to avoid any stress concentrations which would normally develop at some intermediate point on the support frame. Depending upon the width of the building structure, the outriggers 65 are adjusted to properly support the lateral extremities of the building structure. During the transportation of the home from the prefabrication site to a selected location adjacent the foundation site, whenever the trailer encounters any dicult grades in the road or the rear end of the trailer encounters any soft ground which'would cause it to sink and thereby become obstructed, it `would be possible to selectively Aoperate any of the fluid actuated devices seated on the brackets 50 secured to the frame 27 of the wheeled unit from the control station of the prime mover means' to vertically displace the building structure clamped to the carrier frame and support frame relative to the wheeled unit; This would enable the operator of the prime mover means to relieve any bending stresses which perhaps would develop in the building structure when negotiating difllcult grades, and to facilitate removing the trailer from the obstruction caused by sinking in soft ground.

To transfer the building structure from the trailer onto a selected foundation site, the trailer is positioned at a location adjacent the foundation site, as illustrated in FIGURE 10, so that the axis of the trailer is substantially perpendicular to the contemplated line of travel of the building structure along which the building structure will' travel onto the foundation site. As soon as the building structure is properly positioned, as illustrated in FIG- URE l0, the clamping members are removed from the trailer so that the building structure is detached from the trailer. The building structure then is jacked up free of the trailer, by means of any suitable jacking units 99. The trailer is then disassembled by detaching the

support beam members

68, 69,' 70 and 71 from the carrier frame 21 and the coupling member 23, which are then positioned on suitable jacking units in parallel spaced relation along the contemplated line of travel for the-building structure from its elevated position at the location adjacent the foundation site onto the foundation site, as illustrated in FIGURE ll. When the support beams are positioned along the contemplated line of travel, the upper surfaces of the support beams provide guide surfaces defining a track for a plurality of roller members 100, as best illustrated in FIGURES 12 and 13. Each of the roller members comprises a horizontal plate memberv 101 having parallel spaced depending

flanges

102 and 103. Disposed between the depending

flanges

102 and 103 is a roller 104 freely mounted on an axle member 105, which is journaled in the depending

flanges

102 and 103 and a roller 106 keyed to an axle 107 which also is journaled in the depending

flanges

102 and 103. Mounted on the horizontal plate member 101 for rotation in a plane parallel thereto is a seating plate 108 on which a floor joist 25 is adapted to be seated. As illustrated in FIGURES 12 and 13, each of the roller members 100 is adapted to be mounted on the support beams assembled along the contemplated line of travel for transferring the building structure from the location adjacent the foundation site onto the foundation site. The roller members 100 initially are mounted on the assembled support beams delining the transfer track, and are positioned below selected ilood joists of the elevated building structure when in the position as illustrated in FIGURE 10. The building structure is then lowered so that the iloor joists come to rest on the seating plates 103 of the roller members. The building structure can then be rolled along the track provided by the support beam assemblies onto the foundation site.

The building structure can be movedby any suitable means, although it has been found that by extending the axle 107 0n one of the roller members through a depending flange and providing a hexagonal head thereon, the roller members can be driven by means of` a ratchet wrench 109,l as illustrated in FIGURE 13. It will be appreciated that the movable seating plate 108 on each of the roller members 100 permits a limited amount'of adjustment of the building structure in bringing it into proper alignment when moving it into position on the foundation site. v

After the building structure has been transferred into position over the foundation site, the jacking units 99 are then utilized to lift the building structure vertically off of the transfer track. The transfer track and roller members are then removed from beneath the building structure andthe structure is lowered into llnal position on the foundation site. The coupling member 23 is ythen attached tothe carrier frame, as illustrated by broken lines in FIGURE 2, and the transfer track is further disassembled and all the components thereof placed von the abbreviated form of the trailer for the return trip'back to the prefabrication site. The above mentioned procedure is substantially repeated to position the other half section of the building structure onl the foundation site. The two sections are then secured together to complete the nal building structure.

As previously indicated, any suitable jackingunit can be Autilized for lifting and lowering the building structure when transferring the same from the trailer onto the'foundation site. However, referring to FIGURES 14 through 16, there is shown a preferred embodiment of the jacking unit. Each of such units generally comprise a triangularly shaped base member 110 having a vertically disposed cylinder member 111 rigidly mounted thereon. The cylinder member 111 is supported in the vertical position by means of a plurality of support legs 112 secured to the upper end of the cylinder member and eX- tending to the base member adjacent each of the lapices thereof. Slidably mounted within the cylinder member 111 is a uid cylinder 113 having a ram 114 slidably mounted therein. The lower end of the fluid cylinder 113 is provided with a rigidly mounted closure member 115 having a radially extending conduit 116 extending through an axially extending slot 117 in the outer cylinder 111. The conduit 116 is provided with a suitable connector 118 for connecting the iuid cylinder with a suitable iuid pressure source. Rigidly mounted on the upper end of the fluid cylinder 113 is a collar member 119 having an enlarged bore in .the upper end thereof for receiving a packing ring 120 and a packing screw 121. As best illustrated in FIGURE 16, the fluid cylinder 113 can be moved upwardly to the position shown and supported on a diametrically disposed pin member 122 extending through aligned openings in the outer cylinder 111, and uid under pressure can be applied to the uid cylinder to axially move the ram 114 to engage and lift the building structure. It is contemplated that the same fluid pressure source for operating the iiuid actuated devices 52 mounted on the wheeled unit of the trailer, may also be utilized as a fluid pressure source for each of the jacking units in lifting and lowering the building structure when transferring the same from the trailer onto the foundation site.

From the foregoing detailed description it will be evident that there are a number of changes, adaptations and modifications of the present invention which come within the province of those skilled in the art.
