CAR-COUPLING.
SPECFICATGN forming part of Letters Patent No. 589,714, dated September 7, 189'?. Application iiled February 27, 1897. Serial No. 625,354. (No model.)
.To @ZZ whom, t riz-ay concern:
Be it known that I, AMARIAH J. GLENN, a citizen ofthe United States,residin g at Spruce, in the county of Indiana and State of Pennsylvania, have invented a new and useful Car- Coupling, of which the following is a specication.
The invention relates to-ixnproveinents in car-couplings.
The object of the present invention is to iniprove the construction of car-couplers and to provide a simple, inexpensive, and efticient one capable of coupling automatically and adapted to be readily uncoupled from the tops and sides of cars without going between them.
A further object of the invention is to provide a car-coupling adapted to couple readily on curves and capable of automatically uncoupling should acarbecoine derailed eroverturned, whereby one car is prevented from dragging others down an embankment after it.
The invention consists in the construction and novel combination of parts, as hereinafter fully described, illustrated in the drawings, and pointed outin the claims hereto appended.
In the accompanying drawings, Figure l is a perspective view ot a carcoupling' constructed in accordance with this invention and shown applied to a car. Fig. 2 is a front eleva-tion of the saine, the end plate of the draw-head being removed. Fig. 3 is a horizontal sectional view. Fig. 4 is a detail perspective View of thelink-holder. Fig. 5 is a detail sectional view illustrating the manner of mounting the sliding jaws.
Like numerals of reference designate corresponding parts in all the figures of the drawings.
l designates a draw-head provided with a removable end plate 2 and having a pair of spring-actuated jaws 3 mounted in it and adapted to engagea coupling-link 4. The removable en d plate 2, which is secured to the draw-head by suitable fastening devices, is provided with an opening and is beveled around the saine to form a flaring month for the draw-head- The springactuated jaws i), which are disposed vertically, are arranged to slide horizontally in a plane transversely of the d rawhead, and they are supported at their upper and lower edges by transverse rods 5. The
transverse rods 5 are disposed horizontally and the upper and lower edges ot' the jaws are recessed at their inner faces to receive the rods, the jaws being interposed between them and the front plate of the draw-head. The inner edges of the jaws are beveled to forni a daring opening between the jaws, and the beveled edges, which extend to within ashort distance of the top and bottom of the jaws, are adapted, when two cars come together for coupling, to be engaged by the link 4f and spread sufliciently to permit the shoulders 6 t0 pass between t-hein and engage their rear or inner faces, whereby the operation of coupling is automatically effected.
The springs 7, which actuate the jaws for holding them closed and normally in engagement with the link, are disposed on rods 8 and interposed between the outer edges of the jaws and the sides of the draw-head, which is provided with openings through which the outer portions of the rods S project.
The link i has its ends iiattened slightly or reduced in thickness and enlarged, and each end is tapering and substantially arrowshaped, being provided at its opposite faces with tapering enlargements or bosses forming the shoulders G. The space or portion 9 between' the shoulders (i and the central portion ot the link is of sufficient length to permit the necessary play of the draw-heads in order'that the cars of a train may be successively started.
Should a car overturn, the link will twist or turn in the draw-head and automatically spread the jaws and disengage itself there from to effect the operation ot' uucoupling and thereby prevent one car from dragging another after it over an embanlmient or the like. y
The outer ends of the horizontal rods S, which are connected with the jaws, are provided with heads which are engaged by de pending arms of a pair ot substantially L; shaped or bell-crank levers 10. The levers l0, which are uleruined at their angles on the upper longitudinal edges of the drawhead, have their lower ends biturcated and straddling the rods S, and the upper arms of the levers l0 extend inward transversely of the draw-head at a slight inclination ,as clearly illustrated in Fig. of the accompanying `drawin The upper ends of the bell-crank levers are provided with slots ll, which overlap and receive the outer end of a longitudinal lever l2, whereby the latter is connected with both of the transverselydisposed bellcrank levers.
The longitudinal lever 2, which is fulcrumed between its ends on the draw-head, has its inner end arranged in an opening of a vertically-reciprocating slide 115, and the latter is mounted in suitable ways of a car lli and is operated by a transverse lever l5. The longitudinal lever has its inner portion loosely arranged in the opening of the slide, and this connection permits the necessarylongitudinal movement or play of the draw-head.
The operating-lever is arranged in vertical keepers 17, being provided at its ends with suitable handles and at its lower edge with notches 1S, which engage the lower ends of the vertical keepers 17. rlhe central portion of the operating-lever is provided with a longitudinal slot lf), which receives a stud or projection 2O of the vertical reciprocating slide, and when either end of the operatinglever is lifted its other end is fulcrumed on the adjacent keeper and the slide is moved upward to operate the spring-actuated jaws through the longitudinal and transverse le vers.
l/Vhen the link is engaged by the springactuated jaws, it is supported by a link holder 21, mounted iu the draw-head at the inner side of the jaws and provided with a substantially U-sliaped bend Q2, that arches over the link and receives the upper edge thereof.
Any suitable means may be employed for mounting the draw-head on a car, and any suitable operating mechanism can be used for effecting the operation of uncoupling from the tops of cars or the platform of a coach.
It will be seen that the car-coupling is simple and comparatively inexpensive in construction, that it is positive and reliable in operation, capable of coupling on curves, and adapted to couple automatically. It will also be apparant that the operation of uncouplin g may be readily effected from the tops and sides of cars and that the device will automatically uneonple should a ear overturn.
That l claim isl. In a car-coupling, the combination of a draw-head, oppositely disposed sp ring aetuated jaws mounted within the drawfhead, an arrow-headed link, and a transversely-dis posed link-holder mounted within the drawhead in rear of the jaws and provided above the link with a substantially U shaped bend` substantially as and for the purpose described.
2. In a ear-coupling, the combination with a ear, and a draw-head, of spring-actuated jaws mounted within the draw-head, a longitudinal lever fulcrumed on the draw-head and connected at its outer end with the spring actuated jaws,a vertioally-reciprocating slide mounted in suitable ways of the car, having an opening to receive loosely the inner portion ot' the longitudinal lever and provided with a stud or projection, vertical keepers mounted on the car, and an operating-lever arranged in said keepers, provided at its center with a slot to receive the projection or stud, and having notches for engaging the bottoms of the keepers, substantially as described.
S. In a car-coupling, the combination with a car, and a draw-head, of spring-actuated jaws mounted within the draw-head, a vertically-reciprocating slide mounted in suitable ways of the car and having an opening, a longitudinal lever fulcrnmed on the draw-head and connected at its outerend with said jaws, the inner end of the lever being loosely arranged in the opening of the slide and capable of longitudinal movement independent of the latter, and means for reciprocating the slide, substantially as andfor the purpose described.
In testimony that l claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
AMARIAl-l J. GLENN.
