COUPLING-YOKE.

Specification of Letters Patent. Patented S 131 17, 1918,

' Application filed June 6', 1914. Serial No. 843,412;

To all whom it concern:

Be it known that I, ERNEST H. SCHMIDT, a citizen of the United States, residing at Cleveland, Cuyahoga county, Ohio, have invented new and useful Improvements in Coupling-Yokes, of which the following is a specification, reference being had to the accompanying drawings, in which Figure .1 is a plan of my improved yoke, partly in section, applied to the underfram ing of a car; Fig. '2 is a side elevation there of, partlyin section; Fig. 3 is a front elevation thereof; Fig. 4 isa. detail of the filler block; Fig.7 5 is a'front elevation of a modi' fication of my invention, and F 6 is a 'detail of the filler block used with such a modified structure; Fig. 7 is a front elevation. of a further modification, and Fig. 8 is a detailof the filler block used therewith.

My invention relates'to improvements in coupler yokes designed to receive in the forward end thereof the buttend of a car cou plcr, and provides a. strong, simple and convenient form of yoke to which the coupler can be readily connected or disconnected without necessitating removal of the yoke or draft rigging from the car, or the draft rigging and yoke may be taken down without removing the coupler. My invention also consists in the'construction and cooperation" of the parts which I shall hereinafter describe and claim. Referring to'the drawings, the numeral 2 represents the shank of an automatic coupler of any approved type,'which terminates in a butt or liner block? The yoke, which is preferably of cast steel, comprises two parts, the main body portion {-i consisting of the usual upper and lower arms 5 and 6 connected at their rear ends by a vertical portion 7 and a filler block 8 to be hereinafter described. Upon the exterior faces of the yoke 4 is a strengthening rib 9, which is reinforced at the rear end of the yoke by the flanges 10. Theforward end of thearm 5 terminates at the rear of the coupler liner block 8, while the forward end of the upper arm 6 extends over and engages by its abutment 11 the forward face 12 of the coupler liner block 3. Formed integrally with the forward end of the arm 6 are vertically extending side walls 13, the lower rear faces of which are made integral with the for- The forward end of the arm 6 and the Side walls 13 form a housing which incloses the top and sides of the liner block 3'. The side'walls'13 preferably flare forwardly and outwardly, to permit a limited lateral anglingof the coupler relative to the yoke, and therebyrelieve the side walls and the yoke of side strains.

. The side walls 13 are adapted to receive between their lower extremities the filler block 8, and have recesses 1 in which the laterally projecting lugs 15 on the fillerblock V are adapted to enter and which act as a support to the filler block The filler block 8 has also a downwardly extending web'16, re-

inforcing hookshaped flanges 17, which take forward end of the lowerarm 5, anda lip 21, V

which underlies the lower arm 5 to prevent the rear end of the filler from tilting up-,

wardly when a heavy pulling stress is ap plied to the abutment 19 bythe coupler liner block. j I r The pulling stresses transmitted from the coupler liner block to the filler block are taken up by the key member 22, and by it transmitted to the side walls 13 of the yoke. The key member 22 is seated in registering

apertures

23 and 24 in the side walls 13 and filler block 8 respectively. 7

The connection between the yoke and the coupler is made as follows:

After the yoke is placed in position between the draft sills 25 of the car the liner block 3 of the coupler is inserted fromrbelow between the side walls 13, and is then raised so that its front'upper edge 12 engages the abutment 11 of the upper yoke arm 6. The filler block 8 is then inserted from the forward side with its laterallyprojecting lugs 15 seated in recesses let in the side walls 18, and with its upper face 26 engaging the bottom of the coupler liner block 3 and with its abutment 19 engaging the forward face 12. WVhen the filler block has been slid longitudinally into such a position,with its lip 21 underlying the forward The filler block has end of the lower yoke arm 5, the key 22 is inserted transversely through the registering

apertures

23 and 2% of the side walls 13 and filler block 8 respective y. The key may be held in position by any suitable means, such as the cotter pins 27. yoke are open to the rear, and the coupler is prevented from moving farther rearwardly by the usual front follower 28 of the draft rigging, which is inclosed within the yoke.

It will be seen that when the parts are assembled as described, the yoke has a pulling engagement with the liner block of the coupler at the top through the abutment 11 of the upper arm 6, and at the bottom through the abutment 19 of the filler block 8, which in turn is held inposition by the key 22 engaging the side walls 13, so that no securing means for the coupler liner block, other than the key 22, is required.

My invention is of great advantage since it enables the coupler to be secured to or disengaged from the yoke, either by a horizontal or vertical movement, and without the removal of the yoke and draft rigging from the car, for the reason that the positions of the filler block 8 and key 22 may be so low with relation to the plane of the draft sills 25 of the car. that the key can be inserted without interference from the draft sills, as best shown in Fig. 3 At most, a slight recessing of the undersides of the draft sills 25 will provide easy entrance or removal of the key 22, thereby enabling the ready disen gagement or engagement of the coupler and the yoke without taking down the latter from itsposition on the car.

It will also be seen that the engagement of the filler block 8 with the yoke'is such that the side walls 13 are prevented fromv spreading or collapsing; thatthe filler 8 is horizontally and longitudinally slidable into engagement with the side walls 13 and acts as a support for the coupler liner block 3; that the rear end of the filler block 8 prevented from tipping upwardlyby the lip 21 under pulling stresses; that the filler block transmits pulling stresses from the couplerto the key 22 and thence to the side walls 13, and that the key is removable laterally beneath the draft sills without necessitating cutting them away for this purpose.

Copies of this patent may be obtained for The side walls of the In Figs. 5 and 6 I have shown a modified form of my device, in which the recesses 14 cooperate with the projections '15 on the filler block 8 to form'not-only a support for the filler block but also to prevent spreading or collapsing of the side walls 13 through the engagement of the lips 29 on the projections 15 with the depending lugs 30 of the side walls 13.

In Figs. 7 and 8 I have shown a further modification, which constitutes arreversal of the construction I have illustrated in Figs. 5 and 6, the projections 15 on the filler block 8 having downwardlyextending lugs 81, which lugs engage inner faces32 ofthe recesses J1 and thereby not only support the filler block in its position inthe yoke but prevent the side walls 13 from spreading or collapsing;

It is o vious that various modifications may be made in the constructionswhich I have shown and described without departing from my invention.

What I claim is: r

1. A coupler yoke comprising two forwardly extending arms, side walls connected to said arms, a filler block having an engagement with the side walls against vertical movement and having a rearwardlyeX- tcnding lip engaging one of the, yoke arms, to prevent tipping, the said yoke and filler block having bearings for the coupler liner block, and a key member adapted to transmit pulling stresses from the filler block to the yoke. 7 V

2. A coupler yoke comprisingupperand lower arms, side walls extending upwardly from said lower arm to saidLupperarm and forming a housing 'inclosing the top, and sides of the coupler butt, a removable. meme bcr seatingbetween said side. walls beneath said coupler butt and in pulling engagement therewith, said removablegmember, having laterally-projecting lugs seating in lateral recesses in the housing and having also: an interlocking engagement with; the walls of the housing to prevent spreading or-collapsing of said walls.
