HARRY '1. KBAKAU, 0F CLEVELAND, OHIO, ASSIGNOR TO THE NATIONAL MALLEABLE CASTINGS COMPANY, OF CLEVELAND, OHIQ, A CORPORATION OF OHIO.

COUPLING-SUPPORT.

To all whom it may concern:

Be it known that I, HARRY T. KRAKAU, a resident of Cleveland, in the county of Guyahoga and State of Ohio, have invented a new and useful Improvement in Coupler-- Supports, of which the following is a full, clear, and exact description, rei erence being had to the accompanying drawings, forming part of this specification, 1n which- Figure I is a view partly in top. plan, partly ll'hllOllZOIltiLl section and partly diagrammatic, illustrating my improved 'coupler support; Fig; 2 is a view of the same on a larger scale, partly in side elevation and partlyin vertical section; Fig. 3 is a plan view; Fig. 4 is a section on the line IVIV of Fig. 3 Fig. 5 is a perspective view of one-half of the supporting stirrup; Fig. 6 is a perspective view of one of the keys; Fig.7 is a plan view of the carry-iron shoe; and Figs. .8 and 9 are'perspective' .views ofkey members.

My invention has relation to so ports for car couplers, and more particular y for car couplers of the radially swinging type.

I-Ieretofore, it has been customary to royide supports consisting of relatively ong radi'al segments lying beneath the shankaof the coupler, said shank being adapted to slide thereon in its radial movement.

According to my. present invention, I provide the end sill otthe car with a suitable carry-iron support for engagement with a hanger member which, in turn, has a supporting enga ement with the, coupler shank and preferably w th PIOJGCUOIIS on the side The nature of my invention will be best understood by reference to the accompany- .ing drawings. in which I have shown the preferred embodiment thereof and which will now he described, it being premised, however, that various changes can be made in the details of construction and arrangement of the several parts by those skilled in the art, without departingtrom the spirit and scope of my invention, as defined in the appended claims.

in these drawings,- the numeral 2 designates the end sill of a car and 3 is a carryiron support which is bolted or riveted to the front face of .the end sill. This carryiron support is formed with anoverhung portion 4 of trough form.

Specification of Letters latent. Application filed June 17, 1911. Serial No. 633,871.

Patented June 9, 1914.

5 designates a coupler headhaving a rearwardly extendedshank 6, secured to a shank extension 7 in any'suitablemanner, as by the bolts 8. The coupler and its shank extension are arran ed toswii'ig radially from a suitably locate center, indicated at 9 in Fig. 1.

The bottom wall of theoverhung portion a of the carry-iron support is formedwit-han elongated vertical slot 10, 'a'nd'this slot, together with-the curved front face of the support, are on arcs of concentric curves struck from the center 9. The front wall of the overhung portion is backed up by suitable reinforcing ribs. 11, which are cut away,as shown at 11 to permit the movement of the coupler-supporting stirrup, hereinafter described. This supporting stirrup is shown M1 12. It is made in 'two sy1nmetrical halves, one of which is shown in detail in F ig. 5. Each of these halves cornprises a vertical portion having an inwardly projecting arm l9. at its top and an 'inwardly projecting arm 12* near its lower end. The two halves, when assembled,- form a rectangular opening which embraces and entirely surrounds the shank of the coupler. as clearly seen in Fig. 4. The two halves of the stirrup may be secured together in any suitable manner.- ln the drawings, I have shown the arms 12 as having T-slots 12, to

receive a doubled T-headed key 13 (shown.

iii detail in Fig. (5). The lower arms 12 of the stirrup sections support a .carry-iron shoe 14, which rests thereon and is formed with depending lugs 15. which h avea sliding engagement with the armslQ" and are secured by meansof keys l6, driven through openings 17in the arms 12" and against the inner sides of the -lugs 1:"). The key 13 secured by the taper keys '13. The keys 16 serve a double purpose of holding the shoe l t-in position to prevent its sliding laterally and of holding to ether the lower ends of the two halves of the carry-iron stirrup. When the. stirrup sections are assembled in the manner described and the keys 1(3 and 18 are driven to their sea is, the two parts of the stirrup are firmly locked together and inclose the coupler shank in the manner dcseribed.

' The inner-sides of'the vertical legs of the stirrup sections. are.-orrned'with the in-' flanges of the coupler shank, as clearly shown in Fig. 4:. It will be noted that the coupler shank is in this manner held entirely clear of the carry-iron shoe 14 and is supported wholly by lugs 19 with the flanges 20. The purpose of this is to bring the points of support as high as possible and as close as possible to the points of support of the carry-iron stirrup. This greatly facilitates the lateral sliding of the upper portion of the'carry-iron stirrup upon the bottom surface of the overhung channel portion of the carry-iron support,

As will be seen by reference to Figs. 2 and 5, the upper arms 12 of the stirrup sections are formed with the lateral flanges I 12, which rest upon and havinga sliding ofithe radial segments engagement with the bottom n oi elnent. It

surface of the overhung portion of the carry-iron support at each side of the curved slot 10, the vertieal edge of the stirrup extending through said slot at each side of the coupler shank.

My invention provides a support for radially swinging couplers which is simple in its construction and which obviates the use commonly employed beneaththe shank and coupler, and which, while giving proper support to the coupler, also affords the necessary freedom of lateral also ca'n'be readily and quickly applied to and disengaged from the coupler shank.

, its before stated, various changes may be made in the construction and arrangement of the several parts. Thus, support, although preferably an integral casting ofthe formshown, may be made in variougother ways; the construction of the supporting stirrup may als'o be varied and various otherchanges may be made within Lclainii a 1 1. Th" combination with a radiallyvswinging coupler, of a support therefor comjn'ising a earry-ironJsecured to the end sill of a car and projecting forwardly there fron s-aid carry-iron having a trough portion formed with a curved slot in its bottom wall, and a supporting'device having a sliding engagement with the said bottom Wall and extending downwardly through the slot ulnl having a supporting engagement with the coupler, said trough portion having an open top to permit removal of the supportthe scope of the appended claims.

Copies of this patent may be obtained for five cents each, by addressing the the engagement of the provides a support which the carry-iron ing device therethrough, substantially as described.

2. The combination with a swinging coupler having a shank with lateral flanges, of a supporting stirrup embracing the shank and having a supporting engagement with said flanges, together witl stirrup is radially provided ment therewith, the stirrup being comprised of two laterally separable parts depending from a carry iron, and a bottom portion interfitting with the laterally separable parts, the said bottom portion comprising means for securing together the two laterally separable parts, substantially as described. i

5. In a coupler-support a carry iron, a stirrup for supportin the coupler-shank depending therefrom, t e said stirrup being comprised of'tw'o laterally movable, vertically disposed portions and a' bottom portion, the bottom portion comprislng means for rigidly but separably securing together the parts of the stirrup, substantially as described.

6. In a coupler support, a two-part stirrup adapted to form a substantially rectangular structure, and means for rigidly but separably securing together the parts of said stirrup, said stirrup having its side portions provided with coupler supports, substantially as described.

7. A radially swinging coupler having its shank provided with lateral extended supporting flanges, substantially as described.

In testimony whereof, I have hereunto set my hand. HARRY T. KRAKAU.
