GAR-COUPLING.

Specification of Letters Patent.

Patented Dec. 8, 1908. I

Application filed July 2, 1906. Serial No. 324,379.

To all whom it may concern:

Be it known that we, JAMEs TIMMS and JAMES O. TlMMS, residents of Columbus, in

the county of Franklin and State of Ohio, have invented certain new and useful Imlprovements in Oar-Couplings; and we do ereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in 'the art to which it appertains to make and use the same. Our invention relates to improvements in car couplings, the object of the invention be-' mg to provide an lmproved lever constructed tomove the locking device 'to lock set posi tion and then throw the knuckle open, and

v the invention consists .in certain novel features of construction and combinations and arrangements of parts as will be more fully -vated.

hereinafter descri claims.

In the accompanying-drawings, Figure 1 is a view in vertical cross section through the coupler showing the pin in locked position. Fig. 21's asimilar view showing the pin lock ed and pointed out inthe set, the tail of the knuckle being omitted, and

Fig. 3 is a perspective view of a modified form of lever. I

1 represents a coupling head, 2 the tail of a swinging knuckle, and 3- the locking pin to lock the knuckle in closed position. The locking pin 3, when in locking position'projects through an opening or housing 4 in the bottom of the coupling head and is provided with a shoulder 5 to seat on a ledge 6 in the coupling head to support the pin in look setposition when moved to this position by our 1m roved lever 7 as will hereinafter appear.

he lever 7 is fulcrumed between its ends to a depending lug 8 on coupling head 1 and its weighted lower end projectsbelow the rounded. or beveled lower end of pin 3, and this weighted end of the lever is curved or inclined on its upper face where it contacts with pin 3, so that the lifting movement of the lever will not only elevate the pin but will also exert cam action on the pin to force its shoulder 5 over onto ledge 6 and compel the pin to assume its lock set position when ele- The upper portion of lever 7 above its ful crum which lies beside the side wall of the coupling head, is made with an arm or tongue 9 projecting throu h an opening in the wall of the coupling hem and into a recess 10 in the rear or back of the knuckle tail 2, and this armor tongue may project laterally from the lever ,to force the knuckle open. The

4 with an o 7 as shown at 9 in Fig. 3, to dispose the arm nearer the pivotal point of the knuckle so as to require but a slight movement of the lever u per end of lever 7 is connected in any desired manner erating rod or bar 11 extending to the side 0 a car in convenient reach of an operator.

The operation of our improvements is as follows :When the upper end of lever 7 is drawn back'by the rod or bar 11, the lower heavier end of the lever will be moved upwardly-to elevate the locking pin 3, and also by reason of the cam action of the lever against the lower end of the locking in will move the pin laterally until the shou der 5 thereon rests on the ledge 6, thus supportin the pin in its lock set position. .When the 00kmg pin is thus set, the knuckle may be opened by the subse uent separation of the cars. As the knuck e moves to its open position, its tail engaging a shoulder on the coupling pin moves the latter laterally oil the ledge 6 and en ports the pin in its elevated position. W closed the coupling ported thereon, dro s in front of the tail of the knuckle and loc s the latterin its closed position. If the coupling be disenga ed and 1t is desired to manually open the knuckle so as to be in a condition to couple, the cou ling pin should'be elevated as above exp ained, by an outward ull on rod 11 and upward movement of t e lower end of lever 7. After the pin has been seated 'on ledge 6, the bar 11 should be pushed in thus reversing the direction of movement of the lever 7, and forcing the upper arm on tongue .9 into contact with the rear face of the tail of the knuckle. This movement of the lever forces the knuckle to its open position. During its opening movement the knuckle removes the pin from the ledge as aboveexplained and supports it in its elevated posltion until the knuckle has been.

turned to its closed position.

Manychanges might be made in the general form and arrangement of the partsdescribed without departing from'our 1nvention and hence we would have it understood that we do not restrict ourselves to the precise details set forth but consider ourselves at liberty, to make such sli ht changes and alterations as fairly fall within the spirit and scope of our invention.

Tlaving fully described our invention en the-knuckle is again pin which has been sup-i adapted to engage the lower end of the locking device, and having a fixed arm near its other end to engage the tail of the knuckle,

the said lever adapted when moved in one direction to move the locking device to a position where it will be supported and will release the knuckle, and when moved in the opposite direction to engage the knuckle tail to open the knuckle.

2, The combination with a Janney type coupling, of a lever pivoted between its ends to the outside of the coupling and hav ing one integral end projecting beneath the locking device for moving the latter to :1, position where it will be supported i-lllll will release the knuckle, and an integr on the lever projecting through an r 5: in the side wall of the coupling and 121 m it recess in the knuckle tail in position to invocthe knuckle open.

In testimony whereof, we have signed '1 his specification in the presence of twr-t scribing witnesses.

JAMES TIMMS, JAMES O. TIMMS'.
