IN V EN TOR. [7420 4rd fraas ATTORNEY To allwhom it may concern:

Be it knownthat I, Enwnnp G. Gnoss, a citizen of United States, -res1dmg at Columbus, in the county of Muscogee and State of Geofrfiia, have invented a certain new and use Improvement in Car J acking-Frames, of which the following a. full, clear, concise, and exact description, reference be ng had to the accompanymg drawings, forming at art of this specification.

is invention relates to improvements in car 'acking frames.

e object of the invention is to provide a jacking frame suitable for straig temng the underframes and superstructures of steel cars that havebecome distorted service.

and without the necessity of taking the cars apart, thereby eliminating unnecessary labor and avoiding the diflic-ulties heretofore experienced in re-fitting the parts.

The invention, furthermore, 0011818135111 the improvements in the parts and devices and in the novel combinations of the parts and devices, herein shown, described and claimed. 1

In the drawings forming a part of this specification, Figure 1 is a side elevation ofv a car jacking frame showing my improvements in connection therewith. Fig. 2 'is a top plan of the structure illustrated in Fig. 1 'with one corner post in section. Fig. 3 1s a transverse, vertical, section of the structure illustrated in Figs. 1 and 2, only one thrust member C being shown, the thrust member E being indicated by dotted lines, and Fig. 4 is a detailed view illustrating one of the jacks employed.

In said drawing, the frame work is shown as composed of four vertical corner posts A-A, four intermediate posts B-B, two on each side of the frame work near the center thereof, transversely extending channels 10-10 which connect the vertical posts near the bottom thereof and substantially at the ground level, transversely extending upper channels 11-11 connecting the tops of the osts, and diagonal bracing angles 1212 tween the two sets of four corner posts and intermediate posts as illustrated most clearly in Fig. 2. Each of the posts A and B preferably comprises a pair of channels connected by plates to form columns in a well known manner. It will also be understood that suitable gusset plates 1313 are employed on the-top of the frame work to provide means for connecting the diagonal specification of Letters Patent.

angles 12 with the other members of the frame work. At their lower ends, the posts A and B are embedded in a bed of concrete or other suitable body of masonryv 14 which extends beyond the ends of the frame work as clearly appears from-Fig. 1, and which 3 outwardly beyond the sides of the frame work and arranged to bepartly covered over with earth to thereby render the frame work morestable against tipping or tilting. The

vertical posts are also connected at their bottom ends by suitable channels-114 which extend longitudinally of the frame work and are embedded in the masonry. The size of the frame work is made such that a box car, may be run therewithin and for this purpose rails 15-15 are provided suitably mounted on ties 16 and in the to of upwardly extending portions 17-17 0 the masonry bed. Each of the vertical posts A and B is furthermore strengthened against bending by gussets 18--18 secured thereto near their bottom portions, said gussets 18 being in turn secured to transversely extending channels 10 and partly embedded in the concrete or masonry.

has its sides extendedas indicated in Fig.-

Within the frame work, and on each side 7 thereof, is provided a longitudinally exhorizontal thrust member 0 (see Fig. 3). Each of the thrust members 0 preferably comprises a pair of channels 19-19 having the flanges oppositely extended and connected by suitable spacers 20 and eye bolts 21. Each of the thrust members C is made long enough so that it extends from one end post A to the nearest center post B, as clearly appears in'Fig. 1. The thrust members C bear against the corresponding posts A and B and are vertically adjustable by means of tackles 22 suitably supported. from eye bolts 23 fastened to the top members of the frame work. The ropes from each of the tackles may be operated by any suitable winding mechanism and it will be understood that said tackles are detachably connected with the

eye bolts

23 and 21. The thrust members C are adapted to support the jacks D in a horizontal position, each of the jacks D being provided for this purpose with a hook-shaped clip 24 at its base, the hooks 24 being arranged to hang upon the inner flange of the upper channel 0 each member C. For convenience, each of the jacks D may be provided with a erforated ear 25 adapted to receive a hoe 26 secured to a block 27 of a tackle arrangement supported from a roller bracket 28, the roller brackets 28 being supported on a longitudinally extending track 29 mounted on brackets 30 secured to the posts A and B the tracks 29 being located near the top of the frame work and extending preferably the entire length of the frame work so that the jacks may be readily shifted to any desired point. The method of locating the jacks when employed with the side thrust member C is clearly indicated in Fig. 3.

The intermediate posts BB on each side of the frame work are s aced an ap reeiable distance apart as clear y indicated in Fig. 1 and secured to the inner face of each of said posts B, is a vertically extending I beam 31, said I beams 31 being spaced apart as clearly appears from Fig. 1 and forming a verticalguideway for a vertically adjustable, transversely extending thrust member E. The thrust member E is preferably of the same design as the thrust members C, that is, it comprises a pair of channels rigidly connected and has the flanges of the channels adapted to cooperate with the hooks on the jacks D. The transverse thrust member E may also be lifted and lowered by suitable tackles as will be understood. The transverse member E is normally located flush with the top of the central portion of the masonry bed and is provided on its top with short rail sections 32-32 ada ted to aline with the rails 15 and make t e latter continuous. In order to lessen expense and minimize the number of parts, the side thrust members C are adapted to be shifted from one nd of the frame work to the other and to facilitate this operation, a longitudinally arranged series of horizontal rollers 33 are provided on each side of the frame work on which the members C are adapted to be supported While being shifted from one end of the frame work to the other.

In order to lift the car bodies and to separate the same from the trucks, I preferably provide four tackle arrangements 34: located near the corners of the frame work and suitably supported from eye bolts 35 attached to the upper members of the frame work. For operating the tackles, I provide four winches F F to which the pulley ropes ar run. Each of the winches F is secured to a vertical post at a convenient height for the operator and preferably overlaps the connection between the top of the corresponding gusset 18 and vertical post. Each winch F preferably comprises a pair of castings 36 having suitable bearings 37 and 38 for the journals of a winding drum39 and gear shaft 40. The gear shaft 40 is operated by a lever 41,said shaft 40 havin a small gear wheel 42 thereon which mes es with a larger gear wheel {13 secured to the shaft of the winding drum 39. A locking pawl 44 is pivotally mounted between the plates 36' and coiiperates with a ratchet wheel 45 secured to the shaft 40, to thereby lock the parts in any desired position.

At suitable oints, a plurality of rin 46 are provid the same bein retained in fixed position by means of eye olts 47 embedded in the concrete.

The method of using the 'ackin frame is as follows: To straighten t 0 un erframe of a car which has been bowed laterally, the thrust members C-G are elevated to the proper position and jacks applied thereto, two jacks being employed on one side of the car and a third jack on the opposite side of the car which is arranged to engage the car at the center of the bowed or outwardly bent portion. The last named jack is then operated to apply pressure to the side of the car, it being understood that the pressure transmitted to the thrust members C will be taken up by the vertical posts A and B. It will also be obvious that the superstructure of the car can be straightened in the same manner as the underframe by elevating the members 0 to the proper height and applying the jacks in the same manner. When it is desired to straighten the end of a car,

the car is run half way out of the frame work so that the transversely extending thrust member E may be elevated to the proper position and the jacks attached thereto and pressure applied to the end of the car. In this operation, it is necessary that the car be held from longitudinal movement and for this purpose chains are employed which are fastened to any suitable portion of the car, the ends of the chains being attached to the rings 46-4=6. The ends of the super-structure may be similarly straightened as will be apparent. In the event that the underframe of th car is buckled upwardly, chains are passed over the car at the center and attached to said rings 46. The jacks are then used to apply pressure vertically to the ends of the car to thus strengthen the underframe. In the event that the underframe sags at the center, that is, is buckled downwardly, securing chains are passed over the ends of the car and pressure applied by the jacks at the center of the car.

From the receding description, it will be seen that t e car jacking frame which I have provided is of relatively simple construction; may be readily fabricated; is provided with means for straightening the car in any desired direction; and is provided with means permitting easy and convenient handling of the various parts.

Although I have herein shown and described in detail what I now consider the preferred embodiment of my own invention, the same is merely illustrative and I contemplate all changes and modifications that a car is adapted to be received, of vertically.

adjustable side thrust members located between the carand the sides of the frame work and against which jacks are adapted,

to be placed to thereby exert transverse pressure on the car. v
