Definitions
- ABSTRACT A railway draft gear has a housing of box-like shape that is open at its rearward end and is provided with a detachable rear wall for closing the open end. The rear wall is keyed to the housing to anchor the wall against movement rearwardly of the housing. Key stop means is provided on the housing to maintain the keys in place.
- each of which is in opposed forwardly spaced relation to an associated abutment surface on the housing.
- a straight key of suitable thickness is interposed between each abutment surface and the opposing lateral flange to position the'plate longitudinally of the housing and to preclude rearward movement of the plate relative to the housingr
- FIG. 9 is a vertical sectional view taken along line 99 of FIG. 8.
- the draft gear shown in FIGS. 1 and 2 has a generally rectangular in section, box-like housing 10 comprising a pair of vertically spaced top and bottom horizontal walls 12 and 14, respectively, and a pair of horizontally spaced vertical side walls 16 joined to said top and bottom walls.
- the rearward end of housing 10 is open and is closed by a detachable rear wall or plate 18.
- the forward end of the housing has an opening arranged to reof well known construction comprising rubber or simihousing in such a manner as to prevent displacement of 5 the key from its functioning position within the housing.
- FIG. 1 is a plan view partly'in section showing a draft gear embodying the invention.
- FIG. 2 is a side view partly in section of the draft gear shown in FIG. 1.
- FIG. 3 is a plan view of the detachable rear plate member of the draft gear housing shown in FIG. 1.-
- FIG. 4 is a side elevational view of the plate shown in F IG.' 3. v
- FIG. 5 is an enlarged fragmentary view in sectional plan of the lower rearward end of the draft gear hous-
- FIG. 6 is an enlarged plan view of a rearward corner portion of the draft gear housing
- FIG. 7 is an enlarged plan view of one rearward corner of the assembled draft gear with the key in place but with the key retainer plate not applied.
- FIG. 8 is an enlarged fragmentary plan view of a rearward corner of the assembled draft gear.
- coupler buffing forces are transmitted to the gear through follower 36 causing actuation of the friction clutch and effecting compression of pads 26 against plate 18 which bears against rear stops 34b.
- Pulling forcesfrom the coupler are transmitted to the gear through the yoke 38 acting against plate 18, as is well known in the art.
- Side walls 16 of the housing are each extended rearwardly of the end surface 12a and 14a of top and bottom walls 12 and 14, respectively.
- the rearward ends of walls 16 are formed with inturned vertical flanges 17 having forwardly'facing abutment surfaces 17a.
- side wall 16 commencing at a point forwardly of plate 18 is offset outwardly as at 16a to form between flange l7 and offset 16a a vertically extending recess 19 for receiving the lateral flanges 18a on plate 18.
- body portion 18b of plate 18 has a transverse dimension that is slightly less than the transverse v spacing between opposing flanges 17 of the housing side walls. Closure. plate may therefore be applied to the housing end from the top side of the housing as viewed in FIG.
- the vertical dimension"x (FIG. 4) of the forward portion of plate 18 is slightly less than the vertical spacing of thehousing top and bottom walls 12 and 14 to permit movement of the plate forwardly within the housing to the position in which its forward portion is in overlapping relation with those walls, as seen in FIGS. 1, 7, 8 and 9. In this position of plate 18, it is entrapped between the top and bottom walls, thereby assuring that the plate cannot displace downwardly or upwardly out of its assembled position within the housing.
- flanges 18a of the plate are spaced forwardly of and in opposed relation with surfaces 17a on flanges 17 of the housing.
- Key 30 which is straight and of suitable rectangular cross section may now be applied from the top side of the housing and forced downwardly between and in engagement with the opposing flanges 17 and 180 as in FIG. 9, to hold the plate in place against pads 26 and preclude rearward displacement of the plate relative to the housing.
- FIG. 9 shows key 30 in the process of being forced downwardly into place. After key 30 is in place, downward displacement thereof is limited by a shelf 14b which forms a continuation of bottom wall 14 of the housing and underlies the key.
- the length of the key is such that when it is in place in the housing, its upper end is slightly below the top end surface 16t of each side wall 16.
- Surface 16! is flat and is positioned at a lower level than the adjacent top surface of top wall 12.
- a retainer plate 40 is welded to surface 16: in such a position as to overlie the upper end of each key, thereby precluding upward displacement of the keys.
- Plate 40 is preferably of a thickness such that its top surface is flush with, or either slightly below or above, the top surface of wall 12.
- shelf 14b is notched as at 42.
- a suitable tool may be inserted through notch 42 from the underside of the housing and moved upwardly to force the key out of the housing.
- both retainer plates 40 will have been previously detached to permit removal of the keys.
- Plate 18 and housing are so proportioned I that when the plate is in its final assembled position its rear surface l8r lies in the same plane as, or slightly rearward of, rear surfaces 16s of side walls 16, thereby assuring that buffing forces from the coupler will be transmitted through the cushioning pads to plate 18 and thence directly to rear buffing stops 34b.
- plate 18 is in engagement with rear stops 34b and a slight clearance exists between rear surfaces 16s of rear walls 16 and stops 34b.
- the invention provides a simple and effective means of assuring retention of keys 30 within the draft gear housing.
- a draft gear having a box-like housing open at one end, said housing comprising a pair of vertically spaced horizontal walls and a pair of horizontally spaced vertical walls, a removable closure plate insertable between said walls for closing said housing end, one pair of said walls extending rearwardly of the ends of said other pair of walls, each of the rearwardly extending walls having an intumed flange at its end to provide a forwardly facing abutment surface, said plate having a flange portion at each side thereof adapted to be disposed in opposed spaced relation to said surface when said plate is inserted in said housing end, key means insertable between said surface and said portion to limit rearward movement of said plate relative to the housing, fixed stops means on each of said rearwardly extending walls in opposed relation to one end of said key means to preclude lengthwise movement thereof in one direction and detachable key retainer means on each of said rearwardly extending walls in opposed relation to the other end of said key means to preclude lengthwise movement thereof in the opposite direction.
- a housing for a draft gear said housing being of box-like configuration and being open at its rearward end
- said housing comprising a pair of vertical side walls joined to top and bottom horizontal walls, said side walls being extended rearwardly of the ends of said top and bottom walls, each of said side walls having an intumed vertical flange at its end providing a forwardly facing abutment surface, a vertical end plate extending between said walls for closing the end of said housing, said plate having a lateral flange on each side thereof arranged in spaced opposed relation to said abutment surface, a flat key adapted to be interposed between said abutment surface and said flange on each side of the housing to position said plate in a direction lengthwise-of the housing and preclude rearward movement of said plate relative to the housing, each of said side walls having at its lower rearward end a shelf portion underlying said key, the upper end of each of said side walls having a key retainer plate secured thereto for overlapping the upper end of said key.
