Burma roa LOCOMOTIVES.

Application filed February 19, 1927. Serial No. 169,483;

This invention relates to improvements in buffer constructions for use between the locomotive and its tender.

An object of the invention resides in providing a new buffer construction adapted to permit access to allparts ofthe buffer and permit removal of the parts including the buffer springs without requiring detachment of the tender from the locomotive through disengagement of the draw bar connection therebetween. 1

This invention is designed to-relieve the necessity for disconnection of the tender from the locomotive when it is necessary to place shims or other wear take-up devices in the buffer mechanism in order to take up the play in the draw bar so as to retain the proper coupling between the tender and the locomotive and the riding qualities obtained by this proper connection.

The invention more particularly provides a special buffer structure in which the housing for the spring of a buffer mechanism is formed in section in such a manner that the sections may be detached to provide accessto the springs so that they may be removed and replaced or shims may be placed in the housing without disconnecting the draw bar between the tender and locomotive from either one.

Invention includes numerous other ob jects residing in the specific construction and arrangement of the parts which are more particularly pointed out in the following detailed description, and in the claims directed to a perferred form of the invention, it being understood however, that various changes in the size, shape and relation ofthe parts may be made without departing from the spirit and scope of the invention as herein set forth.

In the drawings forming part of this application:

Figure 1 is a vertical longitudinal sectional view through a port-ion of a locomotive and tender showing the draw bar attaching the locomotive to the tender in its operative position and showing the improved buffer mechanism applied to the tender and engaging the locomotive in operative relation.

Fig. 2 shows a plan view of the structure illustrated in Fig. 1, on an enlarged scale, a portion of the cover section for the spring housing being broken away to illustrate the details of construction of the parts.

1 indicates the platform structure at the rear end of the locomotive suitably carried by the frame thereof and which is adapted to receive the floor plates for the cabof the locomotive, also formed to receive the pin 2 for securing one end of the draw bar 3 to the rear end of the locomotive which 'isattached by means of the pin 4.- to the forward end of the frame structure 5 forming part of the water tank of the tender for the locomotive. An arcuate abutment 6 is formed on the rear end of the structure 1 of the locomotive,

and is provided in the usual construction as i now used in the art with a rib 7 along the upper edge thereof for detachably receiving the abutment block 8. This abutment block has a concaved face at 9 in opposed relation to the front end of the frame work of the tender 5 as clearly illustrated in Figs. 1 and 2. I

This construction is of the usual character as in present use in connection with buffer mechanisms between locomotives and tenders associated with and cooperating with the H draw bar connection and forms no part of;

the present invention.

The improvedbulfer mechanism of this invention includes the spring housing member 10 formed of a suitable casting or heavy stamped, or heavy pored sheet material which is illustrated in the drawing as pro vided to receive a pair of spring units 11 in spaced parallel relation as shown in Fig. 2. This spring. housing member has a base portion 12 which is seated against the front end of the frame 5 of the tender and suitably secured thereto by bolts or the like, .while the housing section 13 projects from this base portion and forms the lower half of the spring housing.

The edges of this section 13 terminate in laterally extending flanges 14 provided with suitable openings for receiving the securing bolts 15 adapted to removably secure the cover section 16 to said housing member, and the flanges 14. This cover section forms the otherhalf of the housing for the spring and is positioned so as to be accessible and removable from the top of the'frame of the locomotive, by removing the foot plate between the tender and locomotive, forming the floor of the locomotive cab.

The'buffer member-is indicated at 17, and includes a buffer plate 18 formed of slight arcuate shape to engage the arcuate face 9 of the abutment block 8, while the laterally extending portion 19 from this butler plate 18 is formed'with a pair ofspringreceiving channels 20 to receive the spring units 11.

Pockets 21 are formed at the end of the channels 20, adjacent the butter plate 18 by the flange 22 so as to effectively retain the ends of the spring units 11 in" engagement in the channels 20, while the opposite ends of the springs are effectively retained in the spring housing member through the cooperation of the cover plate therewitl' 'it is desired to talre up play between the ends "When of the springs and the butter plates, the cover sections 1.0 may be removed iromthe spring housing and shims 23' inserted between the ends of the spring units and the base plate I 12 so thatthe sorin 's will be ,maintained ,undersl ght tension ,1n tllQlGlZltlQIl otthe.

parts as shown in .hlg's. 1 and 2, in order that there \vill be no lost motion between the parts.

ny yP of in the art may bejeniployed in connection with thisinvention. lVith the use of the improved construction as above described,

and shown in the drawings, where lost motion may be taken up in this butter mechanism'w thout dlsconnecting the tender from the locomotlve, as required in present a practice, eii'ecting' a considerable saving in time andlabor incident'to such operation as I compared with the present practice, through merely littingthe floor plates of the locomotive cab, removing the cover section 16 spring unit such as now usedwhich provides immediate access to the spring, and permits the insertion of shims where necessary or the replacement of the springs.

Having thus described my invention, what I. claim as new is I 1. A buffer mechanism for locomotives,

comprising a spring housing membert'ormed with a spring receiving section, acover section adapted for'detachable' connection in said.springv receivin section, abuiter unit telescopically associated with said, spring housing, and formed with spring unit'rece ving channels, said cover section retaining said butter, assembly and spring unit in. assembled operativerelation.

channels and casing section of said housing member, and a cover section for said casing section detachably secured to said flanges, said cover section cooperating toretain-said cent the plates, spring units mountedin said buffer unit and spring unit mounted insaid housing member. p
