CAR-FENDER.

Specification of Letters Patent.

Patented Nov. 23, 1909.

T 0 all whom it may concern:

Be it known that we, STEPHEN AARON YOUNGBERG and JAMES BoYn PARNALL, a citizen of the United States of America and a subject of the King of Great Britain, respectively, residing at the town of Rosthern, in the Province of Saskatchewan, in the Dominion of Canada, have invented certain new and useful Improvements in Car-Fenders, of which the following is a specification.

The invention relates to improvements in car fenders, as described in the present specification and illustrated in the accompanying drawings that form part of same.

The invention consists essentially in the novel arrangement and construction of parts wherebythe fender frame is permitted a lateral movement in each direction in relation to the car body on a trackway support and suitably tripped to its lower position.

The objects of the invention are to facilitate the movement of the fender to accommodate the different directions taken temporarily by the car body in rounding curves and to devise a simple, sure and durable form of car fender.

In the drawings, Figure 1 is a View partly sectional and partly perspective of the forward end of a car, showing the fender and operating mechanism attached thereto. Fig. 2 is a plan view from the under side of the fender and operating mechanism. Fig. 3 is a longitudinal section on the line A-B in Fig. Fig. 4 is an enlarged partly sectional and partly perspective detail of the operating pedals and rocker shaft" attached thereto. Fig. 5 is a longitudinal sectional view of the air cylinder, and connections for operating the carriage. Fig. 6 is a sec- I tional view on the line AB in Fig. 2 looking toward the front of the car. Fig. 7 is an enlarged perspective detail view of the rack secured to the carriage and the automatic locking device.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the front platform of a car which is mounted on either a single or double truck in the customary manner.

2 are brackets bolted to each side of the platform 1 in proximity to the front thereof, said brackets extending downwardly for a short distance, and terminating in the bearings 3.

4 and 5 are parallelly arranged arc-shaped tracks extending from side to side of the car platform, and having the outside of the curve thereof facing the front of the car.

6 are end cross bars, and 7 is an intermediary cross bar extending between the

tracks

4 and 5, and forming with said tracks a rigid frame.

The

tracks

4 and 5 are preferably square in cross-section and obliquely set so that the corners form a ridge on the upper and under sides of the said tracks.

8 are studs in axial alinement one with the other, and projecting from the ends of the track 4. The studs 8 are journaled in the bearings3.

9 is a carriage supporting the fender, and traveling on the

tracks

4 and 5.

10 and 11 are bars securely riveted or otherwise fastened together and forming the ends of the carriage 9, said bars extending across from the track. 4 to the track 5. The bars 11 where they meet the track 5 are bent over the upper side of the said track to conform to the shape thereof, and terminate in the downwardly extending ends 12. The bars 10 where they meet the track 5 have the downwardly extending ends 13 corresponding to the ends 12 of the bars 11.

14 are pins extending between the

ends

12 and 13 on the under side of the track 5, the said pins having the grooved rollers 15 mounted thereon, and running on the ridge on the under side of the track 5.

The bars 10 wherethey meet the track 4 are bent under the said track conforming to the shape thereof, and continue for a short distance terminating in the downwardly extending ends 16. The bars 11 where they meet the track 4 terminate in the upwardly-turned ends 17.

18 are short lengths of bar bent in substantial U-shape, andfirmly riveted or otherwise fastened to the bars 10 where they extend on the outer side of the track 4. The bars 18 have the ends thereof bent upwardly at 19 and 20, the ends 19 being similar to the up-turned ends 17 of the bar 11, while the ends 20 are in alinement with the downwardly bent ends 15 of the bars 10.

21 is a pin extending across the upwardly extending

ends

17 and 19 of the

bars

11 and 18, having the grooved roller 22 mounted thereon, and running on the upper side of the track 4.

23 is a fender of any suitable design, but here shown as formed of a mesh 24 extending between and securely attached to the head-piece 25 and the footpiece 26. The head-piece 25 is securely riveted or otherwise secured to the ends and 16 of the

bars

10 and 18.

27 are side rods, or arms extending from the head-piece to the foot-piece 26 and completing the frame of the fender.

28- is a trip frame having the front bar 29 extending across the fender in front of the foot-piece 26. The side rods of the trip frame are slidably arranged in the brackets 30 secured to the foot-piece 26 of the fender 23.

31 is a cross-rod connecting the side rods of the trip frame where they extend to the rear of the fender 23. It will be thus seen that the fender 23 is supported by the car riage 9; the said carriage being supported in turn on the arc-

shaped tracks

4 and 5. The studs 8 pivotally securing the

track ways

4 and 5 to the platform of the car will allow the front of the fender to be lowered on to the track-way, and in order to hold the fender clear of the track when the car is moving, a suspension rod 32 is linked at its lower end to the eye 33 securely fastened to the front of the central cross-bar 7 extending between the

tracks

4 and 5. The suspension rod 32 extends upwardly through an orifice in the platform of the car, and has the forked upper end 34 pivotally secured to the outer end of the lever 35.

36 is a rocker shaft laterally journaled'in the bearings 37 secured on the upper side of. the car platform in a convenient position in front of the motorman.

The crank lever is fixedly mounted at one end of the rocker shaft 36, and as above explained has the outer end thereof pivotally secured to the forked upper end 34 of the suspension rod 32.

38 is a dog fixedly mounted on the rocker shaft 36 intermediate of the length thereof.

39 is a trip lever pivotally secured to the bracket 40 fastened to the platform of the car in such position that the trip lever extends upwardly so that the tooth of the dog 38 engages one of the notches 41 in the trip lever and prevents the rocker shaft 86 from rotating and allowing the suspension rod supporting the fender to drop. The trip lever 39 extends downwardly from the platform of the car. and terminates in the eye 39" through which the cross-rod 31 of the trip frame 28 extends.

42 is a pedal lever fixedly mounted on the rocker shaft 36 at the other end thereof for returning the rocker shaft with the crank lever and suspension rod attached thereto to their raised position where they are held as above explained by the dog 38 engaging a notch in the trip lever 39.

43 is an air cylinder secured to the under side of the car platform by the cylinder stud 44 which extends upwardly through the car platform and is secured by the nut 45.

46 is a piston rod extending through the orifices 47 in the ends of the air cylinder 43, and projecting for a slight distance beyond each end of said cylinder and terminating in the eyes 48.

49 is a piston secured on the rod 46 within the cylinder 43.

50 is an air pipe leading from a suitable supply of compressed air on the car and branched at 51 where it leads to the inlets 52 at each end of the air cylinder 43.

53 are exhaust openings in the air cylinder 43 immediately next to the inlet openings 52.

54 are piston valves arranged in the Valve chambers 55 which intercept the inlets 52 and the exhaust openings 53 of the air cylinder 43. The piston valves 54 are connected by the rod 56 so that the valves 54 normally cover the inlet ports 52.

57 is an arm pivotally secured on the stud 58, centrally arranged on the under side of the air cylinder 43, by the nut 59. The arm 57 at one end thereof is curved upwardly around the cylinder 43 into proximity of the valve rod 56, and has the orifice 60 toward the end thereof.

61 is a pin projecting from the collar 62 secured on the valve rod 56 intermediate of the length thereof.

The other end of the pivoted arm 57 ex tends outwardly from the air cylinder 43 for a short distance, and has the orifice 63 5 toward the end thereof.

64 is a rocker shaft journaled longitudinally in the bearings 65 secured to the under side of the car platform. The rocker shaft 64 at the inner end thereof has the down- 110 wardly projecting finger 66 firmly secured thereto, and extending through the orifice 63 in the pivoted arm 57 67 is a cross-bar fixedly secured to the rocker shaft 64 at the outer end thereof.

68 and 69 are rods pivotally secured at their lower ends to the ends of the crossbar 67 and extending upwardly through orifices in the car platform and terminating in the pedal buttons 7 O and 71.

7 2 is a dog pivotally secured to the bracket- 73 fastened to the under side of the car platform. The dog 72 extends across the rocker shaft 64, and has the downwardly extending tooth 74, which normally engages 125 a curved rack 75 securely fastened to the ends 12 of the bars 11.

76 is a flat spring secured to the under side of the car platform in alinement with the dog 72, and having the end thereof nor- 130 inally exerting a downward spring pressure on the pivoted dog 72.

77 is a T-shaped cam securely mounted on the rocker shaft 6%, immediately under the dog 72 and raising the said dog from engagement with the rack 7 5 on the rotation of said rocker shaft.

78 are grooved pulleys journaled in the sheaves 7 9 on the under side of the platform of the car in alinement with the piston rod 46 and in proximity to the sides of the said car.

80 are cables secured at one end to the eyes 48 at the ends of the piston rod 4:6 and extending around the grooved pulleys 78 being securely fastened at the other end to the eyes 81' on the

bars

10 and 11 of the carriage 9.

The arrangement of the pedal buttons, drop lever and foot pedal on the upper side of the platform of the car will enable the motorman to all times drop the fender as desired without stepping from the car or in any way detracting his attention from his work.

In the operation of the device, it is apparent that very little attention is required by the motorman, as the several parts are all locked or operated automatically other than pressing the pedal buttons or pressing the pedal lever toraise the fender to its upper position after it has been dropped to pick up an obstruction on the tracks.

\Vhen the car is rounding a curve it is only necessary for the motorman to press on one or other of the buttons or 71, when the rocker shaft 6% will be turned, and the cam 77 raise the tooth of the dog 72 from the engagement with the rack, thus leaving the carriage S) free to move on the track-ways I and 5. At the same time the finger 66 at the end of the rocker shaft 6st will move the lever 57, and through its connection with the valve rod and valves, air will be admitted to one end of the cylinder 43 and the piston moved toward one end, and. through the connection of the piston rod 46 and cables 80 the carriage 9 will be moved along the track-ways to the desired position over the tracks on which the car is running.

The release ofthe

button

70 or 71 will allow the rocker shaft 64: to return to its mid-position by the action of the spring 76 on the dog and cam; this shuts off the supply of air to the air cylinder and also looks the carriage on the track-ways by the reengagement of the tooth of the dog 72 with the rack 75.

The fender drops to the roadway automatically when an obstruction touches the trip frame 28, as the cross-rod 31 forming the back is connected to the trip lever 39, and the said trip lever is pushed rearwardly at the bottom which disengages the tooth of the dog 38 from the notch tl, leaving the rocker shaft 36 free to rotate and lower the link rod 32 which supports the track-ways carrying the carriage and fender.

The track-ways are pivoted at the ends at a point in alinement with the rack, and where it is engaged by the dog 72, so that the dropping of the fender and the consequent rocking of the track-ways on their pivot bearings will not interfere with the said dog 72 in its engagement with the said rack 75.
