AUGUST CARLSON, OF PEORIA, ILLINOIS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 491,698, dated February 14, 1893.

Application filed April 30, 1892. Serial No. 431,317. (No model.)

To @ZZ whom it may concern:

Be it known that I, AUGUST CARLSON, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Car-Couplers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which Will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in car-couplers by means of which a car-coupler is provided, being simple in construction, durable and effective for the purpose designed.

More particularly my invention relates to an automatic device purposed to couple by mere contact or by the draw bars being brought together and is accomplished by means of certain hooked-headed pivoted levers acting in conjunction with correspondingly hookedheaded spring levers whereby the connection or coupling process is performed.

That my invention may be more fully understood, reference is had to the accompanying drawings in which:

Figure l shows the draw head in duplicate and in position to be locked or coupled by being borne forward until drawheads contact.

Fig. 2 shows the means of unlocking or uncoupling the device either from the top of the car or from the side.

In the drawings, BAB are drawheads and are purposed to be connected with the cars in the usual manner. They are constructed internally in hollow form but of sufficient (ee) are extensions from and secured to the plates (7i-h).

S-S are springs pui-posed to hold the hooked bars A-A in position.

(it-su) are guide Iianges.

(o o) are pertorations in the ends of the draw bar to provide for use of link and pin, provided such uses are necessary there being of course provided a slot as shown in the middle portion or body and at the ends of the draw bars to provide for the reception of the link. i

In using my improved coupler, it is first apparent that the proportion of the draw-head may not be larger than that of the ordinary and may, in fact be made smaller. The same means for attachment to cars are employed as in the usual coupler which provides sufficient up and down play between the two drawheads.

In operation for the purpose of coupling, the elemental parts of the device having been adjusted as herein shown and the draw-heads borne forward, the hooked bars A-A will contact with and depress the hooked spring levers CAC until, the shoulders pass and the spring levers C-C reacting secure the hooked bars A-A firmly within the respective drawheads, thus effectually coupling the cars and providing suicient play room or space to facilitate the easy starting of the cars. Any tendency of the hooks to become unhooked or the cars uncoupled is overcome by the strong leaf or bar spring C, and also by the pressure of the springs (tl-4) to release the coupling is very simple and is accomplished by merely turning the plate (7L) from the horizontal to a perpendicular position which is accomplished by pressure on the extension (ee,) this turning of the plates (7L-JL) will reverse the position of the hooked bars AA and also the position of the hooked spring plates C-QC, the same being drawn backward by the chain (n--n) being Wound upon the plates (lt-JL) thus providing a ready release or uncoupling of the draw-head and as soon as the uncoupling process has been performed and the extensions (e-e) has been released, the respective parts of the device return imin these positions by means of the springs It will be seen from the device and in its structure thata large provision has .been made for the shifting of the cars unequal motions and for the turning of abrupt curves, this device being especially adapted to overcome the disadvantages possessed. by other couplers in these particulars. Should one ofthe bars bef come released, the connecticngat one side is sufficient to maintain a firm coupling independent of the action of its opposite side.

In Fig. 2 is showna means for operating the device from the side or top of the car in Which figure, (b)shows aconnectionwith the extension (e).whicl1 forms a toggle joint with the long-bar (f.)whicl1 saidlong bar is pivotedfto the lever. (d) .Whichfsaidlever is supported by i presence of two witnesses. and to the long bar (f) and held in the clasp Now by; depressing eitherl of the said l the upright (7c),- m is a bar pivoted to the car levers (myor (d)- the.l uncoupling process is performed but I do not Wish to be conflnedto this specific means of carrying out the un- -f coupling process but that any suitable device may be used that Will perform the office satisfactorily.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is:

1. In a car-coupler the combination With the draw-head of the pivoted hooked bar A, the turn plate h, carried in the lugs G-G, the spring notched bar C, secured within the body of the draw head and adjacent to a recess therein, all substantially as described and set forth. fr i 2. In a car-coupler `the combination with a draw head of the pivoted hooked bar A se.

cured to the turn plate-h, which said plate is fjournaled, as at G--Gf'to turn andvviththe spring S, to holdfthebarAin place,the spring` hooked bar C connected With the turn plate h, by means of the chainn, the spring-z', the extension e, to which may be connected the loperating means consisting of'thebars Z7- -f-m--(Z.suitablypivoted andsupported, all substantially for the purpose described and set forth.

In testimony-whereof I affix my signature in AUGUST CARLSON.
