31 Claims.

Our invention relates to a railway draft arrangement and especially to novel bumng and drafting means designed to be associated with a coupler of the type described in detail in Patent 2,271,770, issued by the United States Patent Ofnce on February 3, 1342, to Edmund l?. Kinne.

The general object of our invention is to devise a draft arrangement for such a coupler incorporating features for centering the coupler and holding it level without the use of separate carrier means.

Our novel arrangement incorporates front and rear followers with resilient means compressed therebetween and auxiliary' resilient means so arranged as to maintain the. coupler in its normal position or to return it to normal position upon horizontal or vertical angling therefrom.

O ur novel structure also contemplates an arrangement w-herein the centering and leveling device for the coupler may be used without resilient drafting means,.if desired.

In. the drawings, Figure 1 is a top plan view of our novel form of draft arrangement shown as applied between the draft sills of a `car structure (otherwise not shown).

Figure 2 is a side elevation, partly in section, of the structure. shown in Figure 1, the section being taken approximately in the vertical longitudinal plane indicated by the line 2-2 of Figure l.

Figure 3 isa fragmentary view corresponding to the showing oi Figure 1 but illustrating ahorizontal angling. of. the coupler..

Figure 4. is. a. fragmentary view corresponding to a, portion of Figure 2 while. illustrating vertical angling.

Figure 5. is a sectional. view through the draft connection,l the. section being taken in the vertical transverse plane. indicated bythe line 5-5' of Figure. 2.

Figures d to 9 inclusive are. views of our novel form of. connecting bolt.. Figure 6 being. a top plan view with a portion of the stern out away, Figure 7. a side elevation, Figure 8` an; end view taken from the left as seen in Figures (i and 7', and Figure 9 a sectionalV view through the pin opening, the.. section being taken approxirrrately in the horizontal plane bisecting the pin opening and as indicated by the, iine. 9".--3l of. Fig-ure 7.

Figures. l0 to 12 inclusive showin detail my novel form of bearing bloeitl Figure 10 being a top plan, Figure Il a. front elevation taken from the right as seen in Figure I0', and Figure l2 a side elevationtaken from the bottom as seen in Figure 10.

Describing the structure in detail, our novel arrangement comprises the spaced sills 2, 2, forming a portion of a car body (not shown), said sills comprising the rear draft lugs 4, 4 and the front draft lugs 6, 6 of usual type. Seated respectively against said front and rear lugs may be the front follower ii and the rear follower i0 with the compression spring |2 confined therebetween. Bearing against the front follower 8 may be the butt end I4 of the coupler I6, said butt end having a dat vertically arranged central face, seating as at I8 against the front follower 8 and having vertical arcuate portions at either side of said flat face, and seating as at 20, 20 against the vertical ribs or shoulders 22, 22 (Figure 3), said shoulders having surfaces complementary to the adjacent portions of said coupler butt in order to accommodate its seating thereagainst. The shank or butt portion I4 of the coupler I6 is formed, with a. horizontal slot 23, flaring at both ends as Well shown in the sectional view of Figure 2, within which may be received the relatively flat head portion 24 of the tail bolt, generally designated 26, said head portion being horizontally tapered as at 21, 21 fore and aft of the pivot point 28 as well seen in the side view of Figure 'I to acA commodate the head 24 in the slot 23 in vertical angling of the coupler. The head y24 may be formed with a vertical pin opening 30 through which may pass the pivot pin 32 (Figure 2), said pivot pin also extending through the vertically aligned openings 34, 34 formed in the shank or butt I4. The rear wall of the tail bolt' pin opening 30 may lbe tapered above and below the horizontal axis of said bolt as seen at 36, 36 (Figure 7) to accommodate said vertical angling and the forward Wall of said opening 30 may be cut away as at 38 (Figure 9) to form an arcuate seat for the bearing block, generally designated 40 (Figure 10) which may seat as at 42 against the pivot pin 32 and as at 44 against the beforementioned recess at 38, said block 40 thus accommodating horizontal and vertical angling of the coupler with respect to the tail bolt 26. y

The bolt 26 may extend through the central opening 46 in the front follower Which may :be reinforced by the annular flange or boss 48, afiording positioning means for the main compres-- sion spring l2. The said bolt 26 may also extend through the central opening 5W in the rear follower lwhich may' aord a seat as at 52 for said spring l2. The opening at 5U' may be large enough to accommodate the bossi 54 formedv on the inner end of the securing' nt 56,. said. nut 56y being spaced rearwardly of the rear follower fr and providing a lost-motion connection between the bolt 26 and the followers. The boss 54 affords on its inner end an annular seat as at 58 for the inner spring 60 which is thus compressed between said securing nut '56 and the front follower 8. It will vbe understood that this inner spring 60, applied under pressure between the front follower boss 48 and the nut 5E, exerts a force to hold the coupler butt I 4 against the front follower, seated at I8, 20, and resists any angular movement of said coupler, whether vertical or horizontal Within the period of lost motion between bolt 26 and the followers.

In Figure 3 is illustrated the condition that takes place under horizontal angling wherein it may be noted that the coupler butt I4 is fulcrumed as at 62 against the face of the front follower 8, a corner radius of the coupler shank being seated against said front follower at one side of the center line of the gear. This angling action has further compressed the center spring 60 due to the pulling of the tail bolt in a forward direction so that the securing nut 56 is seated as at E4 against the rear follower I0. The expansive force of the spring 6i) thus is operative to return the vcoupler to its normal central position as illustrated in Figure l.

The condition which occurs upon vertical angling is illustrated in Figure 4. Here the cou pler is angled downwardly and the extension 66 on the lower rear edge of the coupler butt is fulcrumed as at 68 against the front follower 8 while'the bolt 26 is again pulled forward so that the nut-B is in close proximity as at 70 to the rear follower l0. As in the condition of Figure 3, the auxiliary spring 60 is compressed and the expansive force of said spring exerts pressure to pull the coupler butt back into full engagement with the front follower, as illustrated in Figure 2.

From'the above description, it will be apparent that the action of the centering and leveling means is independent of the main compression or draft spring I2 and, if desired, the centering and leveling device may be used independently of the draft spring. In other words, if desired, the draft spring may be omitted entirely. In such case, the front follower 8 would be a xed member instead of a movable member and the draft spring l2 would be replaced by a rigid member of length equal tothe solid height of said spring l2.

The detail of the tail bolt is shown in Figures 6 to 9 inclusive, wherein it may be noted that the threaded end 12 may be slotted as at 'M to accommodate the retaining bolt 16 (Figure 2) which may hold the nut 56 against rotation of said Vbolt and permit adjustable positioning thereof.

The pin bearing block 40 is shown in detail in` Figures to 12 inclusive and may be seen to be of arcuate form with the cylindrical face 42 on its inner radius for full bearing against the pivot pin 32, said block presenting at its outer radius a spherical seat as at 44 for bearingl against the complementary base on the head of the tail bolt as at 38, as already described.

It will thus be seen that in our novel arrangement we have provided resilient means for accommodating both vertical and lateralangling of the coupler in normal use thereof while at the same time maintaining said Lcoupler in horizontal position where service conditions permit.

It is to be understood that we do not wish to be'limited by the exact embodiment of the device shown, whichis merely by way of illustration and not limitation as various and other forms of the Vdevice will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
