CAR-COUPLING FOR- PIT-CARS.

Specification of Letters Patent.

Patented Nov. 13, 1917.

Application filed February 25, 1914. Serial No. 820,965.

T all whom it may concern Be it known that we, ANTON KoLrsnK-and- MARTIN SonaLA, subjects ofthe'Emperor of Austria, county of Jetl erson and State of Ohio, have invented certain new and useful Improvements in Car-Couplin s for Pit-Cars, of which the following-is a specification, reference being had th rein to the accompanyingdrawing.

This invention relates to car couplers for pit cars, and has for its object to provide a coupler, in a manner as hereinafter set forth,

for quickly and conveniently connecting the set up and comparatively inexpensive to,

manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings,wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a longitudinal sectional view of apair of pit cars, broken away, showing the adaptation therewith of a coupler in ac cordance with this invention,

Fig. 2'is a top plan,

Fig. the coupler, and

Fig. i is a sectional plan.

Referring to thedrawings in detail, 5 and 6 denote a pair of pit cars provided respectively with end sills 7 and 8, and each of said sills is formed with a centrally disposed vertically extending opening 9.

Secured to the bottom 10 of the cars as well as to the sills 7 and S are-draw heads 11 and 12, which are oppositely disposed with respect to each other. The securing means between the draw heads and bottoms 10 are indicated at 13, and the securing residing at Amsterdam, in the 3 is a longitudinal sectional view of means betweenthe draw heads and sills 7 and 8 are indicated 'atl i; Each draw head is rectangular in" contour and closed at its rear as at 15'. The draw head-'11 is provided with achamber 16 a passage 17 communi eating with said'chamber'and afiar-ing open-- ing 18 which terminates at its rear in the passage 17. The top of the draw head 11 is formed with an opening whereby access can be had to the chamber 16,-and said opening is closed by a plate 19, mounted upon shoulders 20 and flush with the upper face of the draw head 11. The plate 19 is maintained inposition by the bottom 10 of the car. The draw head is furthermore provided with'a. vertically disposed opening 21 which intersects the outer end ofthe passage 17 andthe top of said draw head 11, and has a vertically disposed integral hollow boss the opening in the latter forming a continuation of the opening 21. The rear wall of the chamber lo'has a longitudinal lug 23, which opposes a longitudinal lug 2 1 formed on the inner end of a slide block 25, positioned in the passage 17. T he chamber 16 is of greater height than the passage 17, and each side wall of the chamber 16 is formed with a longitudinal groove 26, whichiorms a continuation of the passage 17 and which further provide shoulders 27.

Arranged within the chamber 16.; surrounding a lug 23 and connected'to the lug 2% is a coiled expansion spring 28, the function of which isto move the slide outwardly;

The outward movement of the slide block 25 is limited by a pin '29, which is carried by the lug 24k and abuts against the shoul ders 27. I V

The draw head 12 has its top provided with an opening closed by aplate the latter being seated upon shoulders 31 and 32. The plate 30 is maintained in position by the bottom 10 of a car. The closed end 15 of the draw head 12 is formed with a longitudinally extending lug 32 to which is attached-the inner end of'an expansion spring 3 1, which is of less strengththan the 5 spring 28. The spring 31 at its other end engages with'a lug35 formed on-the inner end-of a coupling bar 37 normally positioned in the chamber 38 formed in the draw head 12 and normally extending through a flaring opening 39, which communicates with the chamber 38. The spring 31 is mounted in the chamber 38. The draw head 12 is provided with a vertically disposed epening 40 which intersects the inner end of the opening 35, and the top of the draw head 12 has an apertured boss 41, the opening therein forming a continuation of the opening 40. The boss 41 is of less height than the boss 22.

The coupling bar 37 has each end thereof enlarged as at 42 and 43. and the former is provided with an oval-shaped open1ng 44, and the latter with an oval-shaped opening 45. The coupling bar 37 is normally posltioned within the draw head 12 and extending through the boss 41 and openings 40, 44 is a coupling pin 46 having a head 47 seated upon the boss 41. The coupling bar 37 is connected to the draw head 11 by a coupling pin 48 which extends through the boss 22 and openings 21 and 43 and said pin 48 is provided with a head 49, which when the pin 48 extends through the openings 21 and 43, is seated upon the boss 22. The heads 47 and 49, when the pins 46 and 48 extend through the coupling bars are positioned respectively in the openings 9, or rather are housed in said openlngs, as clearly illustrated in Fig. 1, the height of the heads being less than the height of the openings. The head 49 is provided with an eye 50 to which is attached a flexible member 51, the latter being connected to an uncoupling lever 52, pivotally supported upon the car 5 as at 53. The lever 52 15 formed at each end with a handle 54. It will be assumed that the pin 48 has been removed from the coupling bar 37 and that the end 43 of said coupling bar is out of the cross head 11. Under such conditions the block 25 has been shifted to a position intersecting the opening 21. The pin 48 rests upon the block 25. The position of the coupling bar 37 with respect to the cross head 12 will be such that the pin 46 is at the outer end of the opening 44, as illustrated in Fig. 4. As the car 6 is shifted toward car 5, the bar 37 enters the opening 18 and abuts against the block 25. When the bar 37 abuts against the block 25, the latter is shifted so that the pin 48 can drop down through the opening 45 and the lower portion of the opening 21, whereby the two cars are coupled. lVhen the pin 48 is shifted from the opening 45, the action of the spring 28 will shift the block 25, the latter in turn shifting the bar 37 outwardly, as the strength of the spring 28 is greater than the strength of the spring 24.

What we claim is 1. A coupler for pit cars comprising the combination with a pair of draw heads, of a spring controlled coupling bar iounted in one of said draw heads, expansion springs bearing against each end of said coupling bar, said spring having a different pressure, said coupling bar provided with a pair of openings, and coupling pins eX- tending through the draw heads and said openings for connecting the bar to the draw heads.

2. A coupler for pit cars comprising a pair ofdraw heads adapted to be secured to a pair of cars, a shiftable coupling bar normally connected to one of said draw heads and capable of projecting from the other of said draw heads, an expansion spring connected to the coupling bar and to that draw head in which the draw bar is normally positioned, a slide block mounted in the other of said draw heads, an expansion spring bearing against said block and of greater strength than the other spring, and means for connecting the coupling bars to that draw head provided with said block, said block capable of shifting said coupling bar from that draw head provided with a spring when the coupling bar is disconnect-- ed therefrom.

3. A coupler for pit cars comprising a pair of draw heads adapted to be secured to a pair of cars, a shiftable coupling bar normally connected to one of said draw heads and capable of projecting from the other of said draw heads, an expansion spring connected to the coupling bar and to that draw head in which the draw bar is normally positioned, a slide block mounted in the other of said draw heads, an expansion spring bearing against said block and of greater strength than the other spring, means for connecting the coupling bar to that draw head provided with said block, said block capable of shifting said coupling bar from that draw head provided with a spring when the coupling bar is disconnected therefrom, and means for limiting the shifting movement of said block.

In testnnony whereof we aflix our signatures in the presence of two witnesses.
