2 Claims.

provide an apparatus of the character stated which can be conveniently operated and which in operation will be efiicient and foolproof.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a front elevational 'view of the apparatus.

Figure 2 is a top plan View.

Figure 3 is an end elevational View.

Figure 4 is a cross-section on the line 4-4 of Figure 1.

Figure 5 is a section on the line 5-5 of Figure 2.

Figure 6 is a side elevational View of the bolster hook and block unit.

Referring to the drawings, wherein like numerals designate like parts, it can be seen in Figure 1 that numerals 5-5 represent the usual trackway rails on which the wheels 6 of a truck generally referred to by numeral 1 can roll, this truck including the bolster 8 having the sides 9 and the journal boxes are denoted by numeral III.

In carrying out the present invention, an elongated bar H of T-shape in cross section has upstanding plates I 2 at the ends thereof through which the elongated tie rod I3 has its ends disposed. Nuts I4 are provided on the ends of the rod 13 and these nuts can be screwed against the plate l2 for tightening intermediate portions of the rod I3 against the upper post portions of the bridge members I5, as is clearly shown in Figure 3. These bridge members [5 connect the upper portions of the legs [6. The bridge members are of substantially inverted U-shape, the upper portions of the leg members being diverged downwardly as at aa and then downwardly in parallel relation as at b-b, each portion 1) being provided with a base member ll. Connecting members l8 are provided between the leg portions a-a. The inverted U-shaped bridge members l5 are filled by web plates l9 through which the bar II is disposed (see Fig. 5).

At an intermediate portion of the bar I I is the bolster lifting block and fall generally referred to by numeral 20. On each end of the bar H is a 5 block and fall assembly 2|.

Each of the block and fall assemblies consists of a Y-shaped upper portion bridged by a roller 23 riding on the portion of the bar H between the adjacent plate [2 and the nearest leg assefn- 1O bly. A cage 2 depends from the lower portion of the frame 22 and has the pulley 25 mounted therein. The assembly 2| also consists of the lower frame 26 having the pulleys 21 mounted therein and the chain arrangement 28 is trained over the pulleys 25 and 21 in the manner of a typical block and fall arrangement. However, the lower frame 26 has a depending leg 29 to which the hook 30 is pivotally connected and this hook is adapted to have several laps of chain 3| disposed over the same and under the upper bar of the corresponding side of the truckas suggested in Figure 1.

The block and fall 20 consists of the upper frame 32 having a hook 33 which is disposed through an opening 34 in the intermediate portion of the bar H This frame 32 has the pulleys 35 mounted therein and the usual block and fall chain arrangement 36 is interposed between the pulleys 36 and the pulleys 31 on the lower frame 38. This lower frame is shown in Figure 6 and includes the depending leg members 39 between which the swingable hooks 40-40 are mounted.

The hooks 4ll40 are engageable against opposite sides of the bolster 8 to the end that when the block and fall is operated the bolster can be lifted.

The assembly 20 is employed to raise the bolster and lower it, while the two side assemblies 2i2| are used to raise the truck side to afford clearance to permit the removal of the wedges and bearings and subsequently the truck sides are removable from the journal by moving the assemblies 2| outwardly. After the truck sides have been removed they can be lowered to the ground with the falls holding them upright so no dust nor dirt can be applied after the wheels are changed from old to new. Thus the journals are protected against foreign matters as well as scratching, by reason of engagement against the ground or other structure.

While the foregoing specificationsets forth the invention in specific terms, it is to be understood that numerous changes in the shape,'size and materials may be resorted to without departing from What is of a pair of leg units, each leg unit consisting of a pair of legs and abridge member connecting the upper portions thereof, a bar extending horizontally and under the said bridge members, and a' tie rod disposed longitudinally of the bar and over the said bridge members and having its ends-secured to the ends of the bar. 7 I

2. A wheel removing and replacing apparatus comprising a frame, a bolster lifting assembly at the intermediate portion of the frame and longitudinally movable truck side handling assemblies at the ends of the frame, said frame consisting of a. pair of leg units, each leg unit consisting of a. pair of legs and a bridge member connecting the upper portions thereof, a bar extending horizontally and under the said bridge members, and a tie rod disposed longitudinally of the bar and over the said bridge members and having its ends secured to the ends of the bar, said bar being of angle iron construction, said side handling assemblies being provided with roller mounts ridable on the said flanged bar.
