METAL BLANK FOR SIDE BEARINGS Filed Aug. 16. 1926 2 Sheets-Swat 2 Patented Now 5, 1929' "UNITED STATES "PATENT; orrics ALBERT 6 WEDGE, OF CHICAGO, ILLINOIS ASSIGNOB; '10 SOPHIE L. WOODS, v CHICAGO, ILLINOIS METAL BLANK FOR SIDE BEARINGS Application filed August 10, 1920. Serial No. 129.370,-

This invention relates to improvements in metal blanks for side bearings for. railway cars and consists of the matters hereinafter described and more particularly pointed out a in the appended claims.

The object of the invention is to provide a blank, which is stamped or cut from a sheet of metal in such way that it may be bent to assume the form of a finished casing, without the use of rivets, bolts or like fastening devices. The several advantages of my invention will appear more clearly as I proceed with my s ecification.

In the rawings Figure 1 is a top plan view of the novel blank from which the improved side bearing casing is made.

Figure 2 is a perspective view illustrating the blank in the first stage of the bending process by which it is brought to orm.

' Figure 3 is a perspective view of he casing as it appears when finished and ready to receive the anti-friction roller and wear plate. Figure 4 is a top plan view on an enlarged scale of the side bearing with the anti-friction roller and wear plate in position therein.

Figure 5 is a longitudinal section through Figure .4 in a plane indicated by the line 5-5 thereof.

Figure 6 is a view representing a transverse section through'the side bearing in a plane indicated by the line 6-6 in Figure 5.

Referring now to that embodiment of my invention illustrated in the drawings which is in the form of a truck bolster bearing: 10

indicates the novel blank from which the imroved side bearing casing is made, Said blank is cut from a flatsheet of metal and comprises

side wings

11, 11 and'an'intermedh atebase member 12. The base member 12 extends at'each end beyond the wings 11 to pro-' vide apertured

extensions

13, 13 to receive the bolts or rivets by means of which the side:

bearing when finished is attached to thetruck l5 bolster to wh'icrl it isapplied, The wings'll,

11 each have extensions, respectively, 14, 14,

and one pair of said extensions on the one win have

lateral tongue extensions

15, 15.

it-h a blank thus formed, the casing is bent to shape as follows: The two wings 11,

11 are bent up at right angles to the base member I2 approximately on lines 12", 12 which define the base and separate it from the wings. This produces the result shown in Figure 2. The

extensions

14, 14 are then bent at right angles to their respective wings along

lines

11, 11 which define

short flangeparts

16, 16 of the wings which project be: yond the lines 12 defining the longitudinal limits of the base member 12 of the blank and whichare severed from said base member, as clearly illustrated in Fig. 1. When the blank is thus bent to form, the bottom ends two wings together to form the end Walls of the casing, said end walls being each made up of the

flange extensions

16, 16 and the

exte'nsions

14, 14 of the said wings.

When the blank is thus bent into shape and the

tongue extension

15, 15 clinched rigidly 8 to embrace the

associated extensions

14, 14,

a strong rigid casing, capable of withstanding the shocks and jars of an anti-friction roller when moving therein, is produced. It will be noted that a space 17 separates the adjacent edges of theflanges 16, thereby providi'ng the usual opening for the escape of cinders, dust and dirt from the bearing.

In the casing resting on the bottom 12 thereof is located a combination wear plate and filler block 18,-whichmay be forged, cast or produced in any'other familiar manner. Said block as shown is provided on its upper face with a de ressed wear surface 19 inclined downwardly rom each end toward the transverse median line, of the casing in order to center a roller 20 which is mounted on said wear plate iii a familiar manner. The roller in this case has no trunnions and is retained in the casing by gravity.

It will be manifest that from the improved blank an open top casing with bottom side and end walls is produced without the necessity of the use of any bolts or rivets to retain the parts of the casing in set up finished form.

I claim as my invention:

1. A sheet metal blank for a side bearing easing, said blank consisting of a base part and of wing parts at the sides of said base part and said wing parts having end exten sions which are are severed "from said base part, said wing parts being adapted to be bent up to form the side walls of the casing and the end extensions ofsaid wing parts being adapted to be bent at right angles to said wing parts into overlapping relation to provide end walls for said casing.

2. A sheet metalblank for a side bearing casing, said blank consisting of a base art and of wing parts at the sides of said ase part, said wing parts having end extensions at their free margins and narrower flange extensions between said margins and the base part, said flange extensions being severed from said base part said wing parts being adapted to be bent up to form the side walls of the casing and theend extensions of said wing parts. being adapted to be bent at right angles to said wing parts into overlapping relation to provide apertured end walls for said casing.

3. A sheet metal blank for a side bearing casing, said blank consisting of a base part and of wing parts at the sides of said base part, said base part having apertured end extensions and said wing parts having end extensions at their free margins and narrower flange extensions between said margins and the base part, the wider extenslons of one of said wing parts having lateral tongue ex-v tensions, said wing parts being adapted'to be bent up to form the side walls of the casing, the end extensions of said wing parts being adapted to be bent at right angles to said wing parts into overlapping relation to provide end walls for said casing witlrthe extensions of said base part projecting beyond the end walls, and the lateral tongue extensions on the wider extensions of one wing part being adapted to bebent down to embrace the like extensions of the other wing part to look the parts of the blank into rigid casing form.

In testimony that I claim the fore oing as my invention, I aflix my signature this 7th day of August, A. D. 1926. x I v ALBERT G. wELon.
