DRAFT APPLIANCE FdR RAILWAY-CARS.

Specification of Letters Patent. Patented June 2(), 1911. Application filed September 16, 1907.

Serial No. 393,213.

To allwhom it may concern:

Be it known that I, VVILLIAM J. MACK, a citizen of the United States, residing at Buffalo, in the county of Erie and State Of New York, have invented new and useful Improvements in Draft Appliances for Railway-Cars, of which the-following is a specification.

My invention relates to improvements in draft appliances for railway-cars.

The primaryobject of my invention is the construct on of an appliance in which any one of 'the various parts may be removed without removing associated parts, and in which the various members are assembled and connected without the use of rivets which are always subjected to strain and likely to shear and in consequence of which the various members of a draft-appliance become loosened and often twisted and displaced under strain, resulting at times in serious accidents.

Another object of my invention is to so construct the appliance that all parts or members are easily accessible and removable from the bottom, so that the loosening of tlieentire appliance from the body of the car is unnecessary.

Other objects are to provide a series of lnili'er-springs so arranged that the end thrusts or shocks to which they are ordinarily subjected will be insuiiicient to set the entire series in action, but upon subjecting the entire series will act to resist the same; to improve and simplify the manner of securing the draw-bar; to tie the sills of the appliances together without the use of rivets with a view of preventing spreading of the Same; and to otherwise improve on draft appliances as will be disclosed in the description of the embodiment of my invention illustrated in the accompanying drawings whic form part of this specification.

My invention consists in the arrangement and combination of parts and in the construction thereof, as will be hereinafter described and more particularly pointed out in the subjoined claims.

In the drawings,-Figure 1 is a pera draft-appliance embodying my. invention; the same being shown in continuous. form inwhich the. sills extend from end to end of the duplicated and one applied to each end. elevation of approximately appliance. Fig. 3 is a plan view of the same. Fig. +1 is a bottom plan view of the same. Fig. 5 is a central longitudinal section taken on line 5 -5, Fig. 3.

Fig. 27 is a perspective view of one of the single spring-followers. Fig. 28 is a perspective view of one of the double springfollowers.

Referring 'now to the drawings in detail, corresponding letters of reference refer to corresponding parts in the several figures.

The reference letter A designates the longitudinal sills of the car, formed preferably of rolled iron or steel having upper and lower marginal flanges a; and in addition thereto, each sill has two intermediate flanges a which greatly strengthen the sills and. counteract the tendency of their buc- Fig. 2 is a side one-half of the for the bolsters which lie transversely thereof and in contact with said ends.

Further description will relate to the various associated parts at one end of the appliance, the description of one sufficing for both, as they are exact duplicates.

D represents a draw-bar and spring housing preferablycast in one integral piece and comprising side members a, a rear trans verse wall (P, a solid portion (Z a transverse wall d between said rear wall and said solid portion and connected with both by a longitudinal partition d forming two spring pockets (Z and a front cross-bar The front of the housing is open, and the side walls of this portion gradually thickened rearwardly to form asubstantially V-sha-ped pocket (Z having a parti-cylindrical recess (Z at its rear end. Overhanging the rear end of said V-shaped pocket is a wallE having a pivot-hole 6 whose axis is coincident with the axis of the recess (Z Vall E also has a segmental slot 0 having the axis of the pivot-hole e as its center. The bottom of said V-sliai'ied pocket is closed by a removable supporting-plate F having a pivot-hole f coinciding with the pivothole e in wall E, and a segmental slot 7' in advance of said pivot-hole having its center coincident with the axis of said hole. On the inner face of said plate is a depression f and on opposite sides of said depression, openings f are formed through which extend lugs d depending from the bottom of the housing D. Keys 7 are passed through said depending lugs and are held against displacement by ,pins f passing through said lugs and keys, as best shown in Figs. 14 and 16. At the rear end of said supportingplate, upstanding lugs f are provided which enter recesses (Z in the underside of the housing. 'A depending transverse housing f is provided at the front end of the plate, the interlor being cylindrical to receive two coil springs G. The endsof said housing, which for convenience of description I will term a spring-housing extend beyond the sides of the main portion of the supportingplate and have upstanding lugs 7 which enter downwardly-opening pockets (Z in enlargements (Z at the front ends of the side walls of the housing D. Said enlargements and the entered lugs f are pierced with coinciding. apertures 03 and 7", respectively. Surrounding the ends of the spring-housing and the enlargements d at the front end of housing D are retainer-bands H which have apertures ]lthat register with the apertures dt and f; a key M being passed through each set of registering apertures, as-clearly shown in Fig. 19. Said retainer-bands are held in place at their upper ends by their being confined within grooves d which are formed on the upper faces of the enlargements (Z and they are also provided with apertures 71 which register with apertures f in the ends of the spring-housing. Passed through said registering apertures k and f are keys 71 which in addition to locking the band H in place, also serve as abutments for the springs G. The front cross-bar (Z is provided with a horn (Z which is designed to strike the end sill of the car and limit the inward movement of the housing D.

The walls of the'V-shaped pocket in the housing D are provided with T-shaped notches each comprising a verticalportion al and a horizontal portion (Z Bolts I are held in said notches, the heads thereof being confined in the horizontal portions (Z and the shanks passed through the vertical portions (Z and through apertures f in the support-ingplate F, best shown in Fig. 15; nuts 2' being applied to the outer threaded ends.

From the foregoing it is clearly apparent that by means of the lugs d and their cooperating keys, the bands H and the bolts I, the plate F is securely held in place,

the three forms of fast-enings against dislodgment under all conditions of usage, and in corqunction with the lugs and f breaking or straining of the plate under the crushing and drawing action of coupled cars is impossible.

Within the V-shaped pocketof the housing D, the draw-bar pocket J is removably held; said pocket having a reduced inner end portion J terminating in an enlarged substantiallycylindrical portion J which fits into the parti-cylindrical recess (Z in. the housing and has pivot-trunnions j which insuring enter the pivot-holes c and f in the overhanging wall. E of said housing and the sup-' porting-plate F, respectively. The rear end of the drawbar pocket has an extended power portion 7' which enters the depression f in plate F, the shoulderj formed by said extended portion being in contact with the front curved wall 7* of said depression, thus relieving the pivot-trunnions j of considerable strain. Lugs j are formed on the upper and lower sides of the draw-bar pocket which extend through the segmental slots 6 and f serving under severe strain to relieve the trunnions. Lugs j and the shoulder j on said pocket positii'ely prevent shearing of the pivot-trunnions, and are so arranged that the pocket can be easily removed from the housing D; it being simply necessary to remove the supporting-plate .F.

front end of said draw-bar pocket comprises a bottom wall 9' recessed T he open at its lnner end, as at f, and sidewalls j; said walls formingthepocket proper, and

. 'sions in, k at the top and bottom, respectiv'ely, formin tensionlc at t is the recess 7'; in the bottom wall of the pocket,

The shank of the drawway dental dislodgment tu'res ofcorresponding ends coinciding;- and through coinciding apertures, pins yo re-member Z which arm Z? of the bar is pierced transversely to form a keysee Figs. 6 and 17, and the side walls of the draw-bar pocket have open'in s j which register with said key-way; t e shank and pocket being secured together by a key In passing through said openings and A6 is key-way, the ends of said key projecting at' Formed in the side-walls of coinciding openings j which of the enlarged rear-end of in a plane directly above the of said shank. Passing through these 0 enings and bearin against the to of the s ank and the shouFder k is a key y" which'has its ends rotruding from the walls of said pocket. 0 prevent acciof the keys is". and 7' opposite ends of both are provided with apertures is", best shown in Fig. 17 the aperopposite sides. said pocket are are in advance said shank and main portion 3 are placed.

The spring-housing f at the front end of the supporting-p late F er wall through in -bracket L. This bracket comprises a rides on the top of said housing and receives the shank of the drawbar, and an arm Z depending from said eke-member and passing through slot f into said housing; pins 1 extend from opposite sides of arm Z and enter the inner ends of the spring G, the arm Z within said housing. Said springs bear at their inner ends against the centering-bracket and at their outer ends against the keys h, previously referred to. -By; this arrangement, the draw-. bar is normally. held in a central position. With a view of reducing the friction of the draw-bar when moving over the bracket, 1 provide a roller Z which is revoluble in the yoke-member ofsaid' bracket. To prevent spreading of the sills, which should always be retained in proper position to provide for properly guiding the housing D in its move- ,has a'slot f in its ments I employ a transverse retainer-bar M at the front ends of the sills; said bar havextenv draw-bar and spring-housing which extends a center-- which latter serve to center .ifree of the clips,

ing opposite ends bent upward and inward to provide hooks m which hook over the lowerfouter marginal. flanges of the sills. Said bar in addition to preventing spreading of the sills incidentally serves as a support for the bearing-plate F. In order that this bar may be quickly and conveniently applied or removed without disturbing other parts of the appliance, the flange of one sill is notched, as at m, to permit one of the hooked ends of the bar to be engaged with or disengaged from the sill. As shown in Fig. 4. the bar and cooperating flanges are provided with coinciding apertures through which pins m are passed which serve to lock the retainer-bar against movement lengthwise of the sills. 1

Within each of the pockets d of the housing 1), I insert two springs N having oppo site ends confined within annular flanges it lar flanges n on followers N O O designate combined follower abutments and sill retainers which havetheir opposite ends notched, as at 0, toiit over the lower flanges of the sills and to bring the intermediate portions inner lower flanges of said sills. abutments are located verse walls (Z and d and beneath the rear extremity 'of the solid portion d ofthe I); the intermediate abutment O being hollow and provided on its ,front and rear sides with elon- These gated openings 0 which receive the ends 0 of follower supports 0 formed integral with the front and rear. abutinents, as

best shown in Figs. land 21. Between the rear and intermediate abutments and the walls d and 623, respectively, and between the front abutment and the rear end of the solid portion 41 of the housing I), lock-keys .0 are located which extend through open-' ings 0 in the sills Al The abutments and keys 0* are locked together by-means of clips 0 that surround theends of the abutments and keys, said clips being passed through openings 0" in the lower outer sills. In order to remove the abutinents, the lock-keys 0* can be removed with the clips.'- When applying the abut-ments, it is simplynecessary tovslip the clips over the ends of the abut- 1nent s,.force the clips 0- through theopenings 0 in the flanges of the sills, and insert the lock-keys 0* through the openings 0 in. the sills and through the clips held in posi-- 'tlziion-i'for .thepurpose of receiving the lockeys.

lock-keys all act in conjunction with the abutments to check the movement of the spring-followers, and the connections thereof between the I beneath the trans are forced'from their seats until after which the abutments 1 flanges of the causing butler of the abvlments by means of the followersupports 0-", am to tie them together and prevent forward and rearward deflection of the same under the thrust and drawing strain to which they are subjected. The spring-followers also bear against -abutments I that are located above the transverse walls 1 and d and above the rear end of the solid portion (Z of the housing D; said abut-ments being in the form of bars that are disposed transversely and are heldin openings 7) in the side-sills, see Fig. 18. I have provided straps p and bent'the same to form pockets 71 in which the. ends of the abutments are held; said straps are secured to the underside of the upper outer flanges of the sills. Thesestrapsv serve to relieve the sills of strain and prevent wearing at the ends of t e open-- lugs 72. 1

Q represents a plunger which is guided between the inner flanges of the sills and hes rs against the rear transverse wall of the draw-barand spring-housing D and against the abntincnts P located above and below said rear wall, respectively. Said plunger is in the form of a yoke having an open center through which may be passed the king-bolt of a truck beneath. When the various parts are in normal condition, or when the housing I) is drawn forward, the plunger bears against the abutments l asso ciated with the rear transverse wall of said housing; but when the housin is thrust rearward, it moves between said abutments and forces the plunger rearward; the latter springs R ,tobe compressed. Said last-mentioned springs herein shown as four in number, are confined between followers R R, which are normally in contact with the rear end of the plunger Q. and with abutments 1-, respectively; said abutments beingv also in the. form of bars disposed transversely and passed through openings r in the sills. Between the springs R, a divider R is located; it havingfour .coLc-aved sides against which the springs R bear: Said divider is preferably hollow and provided with elongated openings 7* with a view of reducing its wcight.

S designates a follower bearing against the rear sides of the: abutments 1* whereby its forward movement is limited and it has forwardly extending stems s which extend into the side springs It, as clearly shown in Fig. 6. Said stems are adapted to 1QCGl\Q' the thrust of the plunger Q after the springs R are compressed to a certain extent. Follower S has an annular flange S which forms a pocket on its rear side in which the frontendof a still buffer-spring S is held; the rear end of said spring being confined in a pocket It formed on the front side of an abutment T helt between the flanges ot' the sills A and bearing against stopt flates U riveted to said sills on the inner sides thereof.

underneath the butter springs R is a spring-retainer V in the form of a bar having av depressed intermediate portion 1; and its ends passed through openings o in the sills A, best shown in Fig. 9. support V is located underneath the. bufi'erspring S the ends thereof being passed through openings 20 in the supplemental sills.

From t he'foregoing description'it is apparent that the springs con-fined'within the housing ward and inward movement of said 'housing, and that the s rings -R are merely com pressed on the slightest inward movement of the housing D, but always in proportion to said movemenh' while vthe-spring S is designed to takeup severe shocks only and is not placed int'oaction until after. the springs Rare coin'pre'ssed'to a certain extent.

It is to be understood thatthe arrangement herein shown and described may be modified in many ways without departing from my invention or sacrificing any of the advantages thereof, andthat any -.part'or parts of the appliance maybe omitted and the remaining parts used in operative asso- -c1at1on or in connection withother parts.
