CAR-CUPLING.

SPECIPICA'IION forming part of Letters Patent N0. 388,288, ated March 27, 1888.

Applieation filed November 23, 1887. Serial N0. 256,017. (N0 model.) V

T0 all whom z3t may concern:

Be it known that I, Bus12f F. LAIRD, of Ocean Springs, in the county of J ackson and State of Mississippi, have invented a new and useful Improvernent in Gar Oouplings, of whieh the following is a specification.

My invention is an improvement in earcouplings; and it consists in certain features of construction and nove1 comb inations of parts, as will be deseribed and claimed.

In the drawings, Figure 1 is a perspective v1ew of my improvements in place on a car. Fig. 2 is a vertical longitudinal sectionof a draW-head provided with my improvements. Fig. 3 is a vertical cross-section of the drawhead and improvenuents. Fig. 4 is a detail perspective v1ew illustrating the operation of Fig. 5 is a detail view 0f the sw1ng-rest or pin-support, and Fig. 6 is a detail view of a supplemental Pinsupport.

The draw-head Ahas a link-mo1tise, a, upper and lower pin'-opnings, B G, and lateral holes D for the bolts or pins which form pivots for the pin-supporting devices. It is usu'al to augment the top bearing, B, for the pin by forming flanges depending from and projeot ing above said top bearing and surrounding the same, the t0p fiange, E, being utilized as a bearing or Portion for engagement by the pinanchor. This provision of flanges above and below bearing B extends such bearing, enabling it.to guide the pin better and furnish more support for such pin. Manifestly, these extensions 01 flanges may be secured b'y casting then1 integral withthe draw-head or formin g them separate from and suitably attaching them to such draw-head, as may be desired.

'Ihe bearing E for the pin-anchor is by preference circular and provided with a rib or bead, e, for engagernent by the anch0r, such rib being preferably seeured by forming a groove, e, below it, as shown. 'The pin-anohor F is pref rably made in the form of a 1ink pivoted at one end to the pin G, near the upperend of the latter, and having ab its opposite erid a hook er shoulder, f, to engage the bearing of the draw-head. In the construction shown the anchor is so connected with the pin that it may fall in either of two opposite directions, and is proVided with two hooks 0r shoulders, f, on two opposite sides, so that it may fa11 in either direction and will properly engage the bearing in either case. In the construction shown'the pin is free to rotate, so that to enable the proper engagement of the anehor with the bearing. I

cling the pin-opening, so that no matter at what point the anchor may fa1l itwil1 engage the bearing. Manifestly shou1d the pin be prevented in any way from rotating and the pinanchor be arranged to fall only in one direction but a single hook or shoulder on the said anehor wonld be necessary, and a beaiing on but one side of such pin would be' required. I prefer, however, t0 arrange the anohor to fall ineither direetion and. to provide bearings on opposite sides of the pin, as theteby a better action of the anchor is seeured, and it is also form the latter cireular 01 endless and eneirpin should be jarred or pressed'upward inany ma1iner the anchor will engage the beaxfing and prevent the pins being drawn or forced up 1n use. v

In order to adj ust the anchor out of position t0 engage the bearingwhen it is'desired to raise the pin, I preferably arrange said anchor to be operated out 0f such positionby the oh'ainor other eonneetion, H, employed toelevate the pin. This eoaction of the pi1ri-1iftihg connection and ancho'r is preferably effe'cted by making the anohor the medium thr0ugh whichthel lifting-connectidn unites with the pin.

In speeifically deseribing the anchor F it maybe said to have an arrow-head, F, pro-'90 vided at its ends with studs f, to facilitate the atta;chment of the lifting-conneetion t0 it, and

arrns F extended from the head and connecte d by asuitable holt, f or other suitable means With the cou'pling-pin G. This pin G is usually inSerted in the draw-head from be- 10W and has on its lower end an enlargement,

- g, whieh prevents the pin being draWn npward out of the draw-head. The swing-rest 01 pin-support I has. at its upper end ears z'at its opposite sides, perfo- 1ated for the assage 0f the pivot-pins J, and

has a cut-away portion or mortise, i, in its upper side 130 reeeive the coupling-pin, and is provided in its front side with a shoulder, i, forming a seat; for t1he cross-bar k 0f t;he supplemenbal pin-support K. 'Ihis pin-support K has near its ends eyes 0x loops k, whieh receive the points of the pivot-pins J, on wbich this supplemental pin1est: is supported.

In operation the pin, when raised, is supported on the swing-rest; I, whieh swings forward under the pin. A ]ink entering the draw-head engages the swing-resb .and forces said rest. back, when the pin Will fall between the swing-resb and bhe supp lemental pin-support and through the link, seeuring the san1e. If it is desired to uncouple the cars when bhey are jammed together in a train, the couplingpin may be raised, when the supplemental support will swingnnder the pin and will hold its elevated, so that: when the cars are drawn apart; they Will be nneonpled, as Wi 11 be readily understood, the swing-rests swinging forward and supporting the pin.

It; will be nobiced that; the pin-supporb rests normally in the path 0f the pin, and by its weighb counterbalances and holds tahe supplemental pin-Support out ofsueh path; bat when the pin-supporb is pushed rearwardl y int0 the draw-headas when sex*eral cars of a train are jammed together-and hhe eoupling-pin is raisedthe supplemental pin snpport: will swing into the path of and below bhe couplingpin, so thab as the ears are drawn apart the eoupling-pin will be 0ut; of the path 0f 'he 1ink, and the nncoupling 0f the cars will be efi'ected.

Having thus described my invenbion, what I claim as new is 1. In a car-coupling the draw-head having a pin-opening and bearings adjacenb to and 0n the opposite sides 0f Same, combined with the pin fitted to said opening, and a pin-anehor connectxed ab one end t0 the pin und movable 130 0ne 0x the other side thereof and provided als t;he oppositse sides 0f its movable end wit;h hooks 01' shoulders whereby to engage nhe bearings 0n either side of 'ohe pin-opening, substantially as seb forbh.

2. In a eancoupling, a draw-head having a pin-opening and a bearing snrrounding t;he same, combined Wit1h an anchor pivoted ab one end t0 the coupling-pin and having an arrow- 1ike head ab its opposite end forming shoulders or hooks 0n its opposite sides, substantially as and for b11e purposes specified.

3. The eon1bination 0f the draw-head having a bearing, the eoupling-pin, the pinanchor eonstructed wibh an arrow-like head. and having an arm 01 arms extended therefrom and pivobed 130 the pin, and t:he pin-lifting connection secured tzo said head, subsbantaially as Set forth.

4. In a cancoupling, a pimanchor nonstructed Wibh an arrowlike head and having an arm or arms whereby such head rnay be conneeted wibh the coupl'ing-pin, substantially as sei: forbh.

5. In a car-coupling, th e combinabion of the draw-head, Lhe Pivoted swing-rest; 0r pin-support, and the supplemental pin-support pivoted and adapted t0 operate substantially as set forth.

6. In a eancoupling, the combination 0f the draw-head, the pivoted swing-rest or pin-support, and the supplemental pin-support; pivotaed concentrically with said pin-support, substanbially as sei; forth.

7. A car-coupling having a pin-seat movable into and 0ut; ofthe path of the couplingpin and provided with a. supplemental pinsupport; rnovable normally into the path of the pin when the pin-support; proper is pushed rearwardly 011t1 0f normal posibion, whereby the eoupling-pin may be held out; of coupled position when a. train 0f cars is jammed together, substantially as described, and for the purposes specified.

8. The cornbinationin a car-conpling, of the draw-head, the pin-supporb having a seat or shoulder, i", and the suppl en1ental pin-support having a cross-bar arranged 120 rest 0x1 said seab, substantially as sei; forhh.

9. In a ear-coupling, the combination of tbe draw-head, the swing-rest or pin-supp0rt; having a cut-away porbion or mortise, i, and a. seat, 1?, and the supplernental pimsnpporb havinga erossbar arranged t0 resb 011 said seat, substanbially as set forth.
