Specification of Reissued Letters Patent. Rei ed Jul 5,1921

' OriginalNo. 1,343,698, dated June 15,1920, Serial No. 278,252, filed February '20 1919. Application for reissue filed; January 31, 1921.

T all whom it may concern:

Be it known that I, ALLEN WALLACE,- a: citizen of the United States, residing at Moorestown, inthe county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Foot plates for Electric Locomotives, of'which the following is a specification.

I The object of my invention is to improve the construction of the frame of an electric locomotive by providing a foot plate at each end of the main frame of the locomotive,

' formed in such'a manner as'to provide bearings and sup orts for a number of the moving parts 0 the locomotive structure and also the bearing for the trucks at the ends of I the frame. I

In the accompanying drawings Figure 1, is a diagrammatic plan view of 2 a locomotive frame, showing a foot plate at each end thereof; I

Fig. 2, is an enlarged plan View of one of the foot plates;

Fig.- 3, is a side view of thesame; I

Fig. 4, is an end view looking in the di' rection of the arrow 1, Fig. 2;

Fig. 5, is aplan view of the locomotive frame, showing the foot plate and certain parts ofthe locomotive mounted thereon;

Fig. 6, is a side view of the construction' shown inQFig. 5";

Fi 7 isa-transverse sectional view on the line 7 -7, F

Fig. 8, is-"a bumper; and" I .9,-is-an*end view of'the s'ame I Be erringto Fig: 1, 1, 1 are the side memhers-of tlraframeof- 'a locomotive." 2, 2 are" the foot plates, one located at each end of the frame structure andsecurely fastened to the side members. The two foot; plates are identical so that it will only benecessa-ryto describe one in detail: II I In electric locomotive practice at the presenttime,the twoends of' -the locotiv'e are usually similar in construction and the-- several partsoftlielocomotive" are dupli cated, such asth e end trucks ,the bumper,- cou-plings, &;c I

Referring plate has aflange -'extension 3 at each side which is'b'olted, or riveted, to the sidemem= -be'rs-1 of the locomotive frame. At'the-op- 5; etached plan view 'of the to Fi s. 2, 3'and'4; each foot" Serial No. 441,440.

posits end is a portion-4 shaped to receive the: bumper structure 5, Fig. 8-. In some in stances, the bumper structure may be made integral with the foot plate, but I prefer to make it separate so as to avoid intricate castings.

A I Atthe centerof the foot plate'is the bearin for the center pin 7 of an end. truck 8, lgs 5 and'6, which is an ordinary four wheeled truck in the present instance. Di rectly in front of this hearing 6 is; a bearing 9 for the pivot pin 10 of the draw bar of 5 the coupling 11, which may be of anytype I desired. The foot plate is surfaced at" 12 at I each side of the'center back of the'bearing 6' for the fulcrum castings 13 on which are" hung the equalizing beams 14, whicli are ar- 79 ranged at an angle inrespect to thelongh tudinal line of the locomotive-and are connected to a beam 15 at one end, which is supported on-a pin 7 withinthe-pivot 7 0f the truck 8, while the other end of each beam 7 5. 14 is connectedby'a link 16170 one endof a spring 17. The opposite end'of thespring 13 connected by 'a link 18' tothe frame 1; while the spring rests on the box 19- *in' which the axle 20-of one of the driving wheels-is" Q mounted. I i

-On a line with the surfaced portions 12 for the fulcrum castings I of the equalizing beamsl l are surfaces 21 to'- which are' se cured the cab sprin supports- 22, Fig;- 5.'85 At one endi of the Ioot plate are-lugs-23 from which the brake hangers are suspended, and at the" center at the same endas qthe lugs is a support'l24 'to' which the bar 25- is secured which supports the driving motor 90, or motorsuspen's'iom The aidjustahlepilot 26 is also supported 5 by tlie foot-"plate;

' Eachfoot plateis an-integral steel ca'st in-g andn- -ay besur f'aced' at any-point de sired to receive: any parts'of the locomotive, and"can be*"hored or" drilled at different" points for the reception of the other" ele f .ments-than those" shown. a
