`tailed description of preferred embodiments thereof when
`read in connection with the drawings.
`In the drawings:
`Figure 1 is a perspective view of a preferred embodi
`ment of the invention.
`Figure 2 is a fragmentary perspective exploded view
`illustrating the assembly of two of the frame members.
`Figure 3 is a sectional elevation taken substantially on
`the line 3-3 of Figure 1.
`m
`Figure 4 is a sectional elevation taken substantially on
`the line 4-4 of Figure 3.
`Figure 5 is a vertical cross section of a frame section
`constructed in accordance with a modified form of the
`invention.
`Referring now to the drawings, a preferred form of the
`skid structure of this invention is generally indicated 10
`and comprises a pair of longitudinal beam or frame mem
`bers 11 and a plurality of transverse frame or cross-beam
`members 12. The members 11 are substantially identical
`and are generally rectangular in cross section having a
`top 13, a bottom 14 and side walls 15. As shown best
`in Figure 4, the frame members 11 are of two-piece con
`struction, comprising a generally U-shaped bottom mem
`ber 20 and a top member 21, both of a light metal such
`as aluminum. Preferably the members 20 and 21 are
`extruded to form the desired shapes, the bottom member
`20 being provided with inwardly directed longitudinal
`flanges 25 suitably dove-tailed as shown to fit in the dove
`tailed side grooves 26 formed in the top member 21. The
`top and bottom members are preferably welded together
`as at 27, the top member preferably being provided with
`a pair of longitudinal bevelled edges 29 to facilitate
`deposition of the weld.
`The ends of the frame members 11 are of reduced
`cross section formed preferably by providing an upwardly
`inclined portion 30 forming the bottom of each of the
`side Walls 15, the portions 30 terminating in relatively
`short vertical shoulder portions 32 which in turn lead
`to horizontal bottom portions 33. U-shaped bottom
`members 34 and 35 are secured to the end portions of the
`side Walls by any convenient means, such as by riveting,
`to complete the assembly. Preferably the ends of the
`frame members are thus reduced to a vertical dimension
`of approximately one-half the vertical dimension of the
`main portion thereof, the reduced portions extending in
`Wardly from the ends of the members a distance approxi
`mately equal to the width thereof.
`The top member 21 of each of the frame members
`11 is provided with a central longitudinal groove 40
`generally of inverted T-shape, the overhanging top portions
`41 and 42 forming the central, upper groove portion 43
`of reduced width. Preferably the central portion of the
`groove bottom is curved as at 44 to form track surfaces
`45 and 46.
`The Cross-beam members 12 are identical in configura
`tion to the frame members 11 with the exception that
`in the embodiment shown, the members 12 are substan
`tially shorter than the members 11. Like the frame
`members, the cross-beam members are provided with re
`duced end portions having horizontal bottom portions 33a
`and short vertical shoulder portions 32a, U-shaped bottom
`members 34a and 35a, and a central longitudinal T-slot
`or groove 40a.
`Means are provided for adjustably assembling the frame
`members 11 and cross-beam members 12 into a skid struc
`ture of great rigidity and strength, and as shown in the
`drawings these means may include the stud nuts 50, which
`are T-shaped in cross section to be slidably received in
`the T-slots 40, apertured seating washers or plates 51,
`lock washers 52, stud bolts 53 and nuts 54, the bottom
`members 35a being provided with central apertures 55.
`
`This invention relates to the shipment and handling of
`machinery or other articles of substantial bulk and weight,
`and has particular reference to a skid assembly and com
`ponents thereof for handling such articles.
`In the shipment and handling of machinery or like bulky
`and heavy articles, it is customary to secure the article to
`a heavy timber framework commonly known as a 'skid."
`Such skids usually consist of several longitudinal men
`bers of substantial cross section to which are secured, by
`bolting or otherwise, several cross members, likewise
`usually of substantial cross-section. The machine or
`other article to be transported is usually bolted securely to
`... these cross members.
`In the case of a machine mounted upon skid, it is
`essential that provision be made for lifting the article, as
`by a crane hoist, in order to place the article in or on a
`freight car, truck or other transport vehicle. In some in
`stances, attachments for lifting are provided in or on the
`machine itself. In other instances, provision for attach
`ment of hoisting cables must be made in or on the skid
`structure itself. Thus the skid structure itself must be of
`such substantial nature as will safetly support the machine
`while suspended from the hoisting rigging.
`The use of relatively heavy timber for skids, while of
`almost universal application, has a number of disadvan
`tages. The relatively large cross-sectional dimensions of
`the timbers combine to increase the overall height of the
`machine or article as shipped. The weight of the skid
`structure, too, adds considerably to the shipping weight,
`and hence to the cost of shipment. Furthermore, each
`such skid structure must be specially constructed to suit
`the size of the machine, and the positions of the holes in
`the base of the machine for the foundation bolts have to be
`drilled to suit each particular machine.
`One of the principal objects of this invention is, there
`fore, to provide a novel skid structure which is not sub
`ject to the above-mentioned disadvantages of the conven
`tional structures.
`Another object of this invention is to provide a light
`weight, compact skid structure composed of uniform mem
`bers which may be readily assembled in varying sizes and
`configurations to fit varying job conditions.
`Another object of this invention is to provide a novel
`skid structure consisting of a plurality of frame members
`of uniform cross section, the members being provided
`with means for securing the article to be handled thereto
`without the necessity for drilling holes in the frame
`members.
`Another object of this invention is to provide a novel
`skid structure comprising a plurality of uniform frame
`members, the frame members having end portions of re
`duced cross section which serve the double function of
`reducing the overall height of the skid and facilitating
`handling thereof.
`Other objects and advantages of this invention it is
`believed will be readily apparent from the following de
