vv. J. QUINN BRAKE Filed Aug. 23. 1923 IN VEN TOR J3 Quinn A TTORNE YS Patented July 8, 1924.
WILLIAM JOSEPH QUINN, F POTTSVILLE, PENNSYLVANIA.
BRAKE.
Application filed August 23, 1923. Serial No. 659,012.
To all whom z't may concern:
Be it known that I, WILLIAM J osnrH QUINN, a citizen of the United States, and
a resident of Pottsville, in the count of Schuylkill and State of Pennsylvania, ave
invented certain new and useful Improvements in Brakes, of which the following is a specification.
This invention relates to brakes for railroad cars and has for its object the provision of a device which will not only positively control the movement of a car but will eliminate the usual danger to railroad employees when applying` brakes.
A- further object of the invention is the provision of a simple and eilicient device or applying `the brakes to the wheels of a railroad car at a point remote from the end of the car with means for limiting the movements of certain elements of the brake applying device when certain elements of said device become broken.
This invention Will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modications, which shall define no material departure from the salient features of the invention as expressed in the appended claim.
In the drawings:
Figure 1 is a fragmentary view in side elevation of a railroad car showing my improved brake operating means applied to the same.
Figure 2 is a fragmentary view in lon tudinal section. of the brake applying evice.
Figure 3 is a view in perspective'of the means for locking the actuating device of the brake in position.
Referring to the drawings, 1 indicates a freight car having a top 2. Beneath the car is disclosed a portion of the running gear provided with pairs of spaced wheels 3 and 4 which are adapted to be engaged respectively by brake shoes 5 and 6. The brake shoes are mounted upon rods 7 supported by links 8 from the bottom of the car. The rod 7 of the shoe 6 carries a swingable link 9 upon which is pivotally mounted intermediate its ends a lever 10. The lower end of the lever is connected by a link 11 to the rod 7 which supports the shoe 5.
The upper end of the lever 10 is connected by a chain 12 which engages around a pulley 13 pivotally mounted at the rear end of the car 1 and is passed upwardly throu h a perforated cleat 14 and secured to an wound upon a drum or spool 15. That portion of the chain between the cleat 14 and the spool 15 is provided with a laterally projecting lug 16 adapted to engage the upper face of the cleat 14 when the chain becomes disengaged from the spool 15. A U-shaped bracket 13a supports the pulley 13 and prevents chain 12 from becoming disengaged from said pulley.
The spool 15 is rigidly connected to a horizontal shaft 17 which is mounted in a plurality of vertical standards 18 formed integrally with a plate 19.
T e outer end of the plate projects beyond the rear end of the car 1 and is provided with a depending wedge-shaped bracing member 20 adapted to be secured in any approved manner to the rear end of the car. That portion of the plate 19 which extends beyond the rear end of the car 1 supports the ulley 15 between the rear vertical standar s 18. Each of the standards through which the shaft 17 passes is provided at these points with bearings 21. The rear end of the shaft 17 is perforated to receive a cotter pin 22 for maintaining the shaft in position and between the adjacent bearing 21.
Standards 18a are provided on the inner end of the plate 19 and a bearing plate 23 is secured to the upper end of these standards for supporting vertical shaft 24. The upper end of the vertical shaft is provided with a hand Wheel 25. Adjacent the lower end of said shaftis secured a bevelled gear 26 which meshes with a bevelled gear 27 mounted upon the inner end of the horizontal shaft 17 and located between the standards 18".
The extreme lower end 28 of the shaft 24 is located Within a socket in the plate 19. A ratchet wheel 29 is secured to the shaft 24 below gear 26 and is adapted to be engaged by a pawl 30 p-ivotally mounted between ears 31 upstanding from the plate 19 At the upper end of the ears 31 is pivotally mounted an end of a weighted lever 32 with the weight 33 when located in the popawl in engagement with the ratchet wheel 29 to prevent rotation of the shaft 24 when the brakes have been set. By throwing the weight 33 in the opposite direction tovwhlch it is located 'in Figure 3 the end 34 of the pawl may be raised to .disengage the pawl from the ratchet wheel 29.
Beneath the plate 23 and the bearing 35 the shaft 24 is perforated to receive a cotter pin 36 which maintains the shaft in position and likewise the gear 26 in engagement with the gear 27 and bearing 35 in position.
Instead of the vertical -portion of the chain 12, a rod having eyes at each end may be employed with the ends `of said chain which engage around drum 15 and ulley 13 connected to the eye of the rod. ables may be employed in place of the chain and are connected to the eyes of the above inentioned rod.
What I claim is: I
In a braking device for railroad cars, operating means for the brakes and'comprising a plate secured to the top of the car and havin, 1r an end projecting beyond the end of said car, spaced vertical standards formed integrally with the plate, bearings mounted in said standards, a shaft supported by said bearings., a spool rigidly connected with the shaft and located between the standards formed at the projecting end of the plate, a gear mounted on the inner end of said shaft, a vertical shaft mounted for rotation on the inner end of the plate provided with a gear -in mesh with the gear on the horizontal shaft, a ratchet Wheel connected with the vertical shaft, a pawl engaging the ratchet Wheel for locking the vertical shaft against rotation.
