WILLIAM H. MARTIN, OF UKIAH, CALIFORNIA.

CAR FENDER.

'1 b all whom it may concern Be it known that I, IVILLIAM H. MARTIN,

residing at Ukiah, in the county of Men docino and State of California, have invented a new and Improved Car-Fender, of which the following is a specification.

My present invention relates to improvements in that type of street car fenders in,

My present invention in its more specific nature embodies certain improvements on the type of car fender generally outlined in my Patent #1,012,392, December 19, 1911,

that provide a positively acting and eflicient fender and in which is included means for holding the object on the pick-up in such a manner that danger of the same rolling oil; or being crushed as it is carried forward, is reduced to the minimum. a

My present invention consists in the improved construction of car fender, hereinafter fully described, specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the front end of a car, with my improved fender mechanism, the same being shown as down and extended for carrying the object struck. Fig. 2 is a similar view, the fender devices being at their up or folded position. Fig. 3 is a front view of a car body with my fender mechanism applied, the latter being at the elevated position. Fig. 4 is a detail view of the front or drop canvas and roller hereinafter referred to. Fig. 5 is a detail view of one end of the winding roller for the said canvas. Fig. 6 is a side elevation of one end of the car, the fender devices being at the swung-up or folded position in full lines, and at the down or tripped position in dotted lines. Fig. 7 is a detail sectional view of one of the spring connections for the rock shaft. Fig. 8 is a detail section that illustrates the buffer-frame manually-operated releasing devices.

In the practical adaptation of my present invention, I use two rock shafts 23 mount- Specification of Letters Patent.

ed in the side brackets 1, secured on the car front and having cylindrical casings 40, in which are mounted coiled springs 41 that cooperate with the shaft 2, and which normally tends to rock the said shaft outwardly, see arrow m, Fig. 7 At their opposite ends, the

shafts

2 and 3 carry intermeshing gears 4 and 5, the shaft 2 also carrying at the said opposite ends outwardly, downwardly and rearwardly curved side arms 6, the purpose of which will presently appear.

13 designates swingable side arms fastened to the shaft 3 and to the gears 5, to swing in the vertical plane, and on the outer ends of the said arms 18 is ournaled a winding roller 14 to which is connected one end of a drop apron 15 from the lower end 16 of which hangers 17 are pendently supported, the said hangers being apertured to receive the journals 18 of a drag roller 18. The said journals 18" extend beyond the hangers 17, so that they may rise into and seat in recesses 20, formed in side extensions 19 on the front ends of the arms 13, such arrangement of parts aiding in prop erly supporting the drag roller when the fender is at the elevated or folded position shown in Figs. 2, 3 and 4.

21 designates a flexible hanger that includes a ball-like head 21 secured to the lower front end of the apron 15 which has for its purpose to hold the drop apron 15 and the roller 18 to its vertical position when the fender is set to the position shown in Fig. 2.

12 designates a canvas apron that may be wound on a roller 10 mounted in brackets 11 pendent from the car frame, and having a journal extension for receiving a crank 10*.

29 designates ropes or chains for sustaining the side arms and their attached parts in their dropped position, and they are se cured at the upper ends to the car body and at their lower ends to the outer ends of the side arms 13.

The canvas apron 12 connects at its for ward end with a cross rod 7 that joins the lower ends of the arms 6.

8 designates a sheet steel catch platform hung at the rear end on the cross rod 7 and having its front edge turned down for readily sliding over rough surfaces. Flexible hangers 37 are secured to the platform 8 and include eye members .57 for engaging holding bolts hung from the side arms 6 and which are slidable in keepers 36 on the car body.

By reason of the peculiar construction and arrangement of the parts as described and shown, when the roller 10 is wound to take up the apron 12the side arms 6 are swung backwardly and upwardly to the position shown in Figs. 2 and 3 and in doing so the gears 4 on the arms 6 turn the gears in the direction indicated by the arrow 1 and thereby swing the arms 13 to the vertical position shown. After the arms 6 have been swung back as stated. the free ends of the hanger bolts 35 are inserted by hand through the keepers 3G and the eyes 37 on the members 37, which serves to hold the arms 6, and the platform 8 up under the car in position to be shot forwardly in the manner presently to be explained. After the arms 13 are swung to the vertical position, as stated, the flexible hanger 21 is slipped between the pincer-like clamping jaws 24, normally closed by the spring connection 34, that joins with the upwardly extending members 2 1 of the jaws, the latter being pivotally mounted on a bracket 24 on the top of the car.

22 designates a buffer-frame preferably formed of light metal tubing and the same includes side members 22 having bearing portions 23 that fixedly engage with the rock shaft 2, a bottom bar 26 having end pintles 26 (see Fig. 6) and a supplemental frame 25, pendent from the bottom bar 26 and hung on the pintles 26 and formed with crank portions 25* that project inwardly to the rear of and normally engage the side members 22*.

The object in pivotally suspending the lower or supplemental frame 25 is to allow it to lift up on coming in contact with the roadway when ascending a steep grade from a level crossing, it being apparent from the drawing that since the frame 22 is rockably mounted in striking an object the lower part will be swung backwardly and the upper end correspondingly outwardly, and at this point, it should be stated, that the outward swing of the upper end of the buffer frame is what effects the release of the side arms 13, the apron 15 and the roller 18 carried thereby, such release being effected in the followmg manner.

A counterbalanced frame, which includes a bottom cross rod 31 and upright rods 32, is slidable in bearings on the car dash, and on the roof beam above which the rods 32 project. Flexible connections 30 pass over pulleys 30 connect with the cross bar 31 of the counterbalanced frame and join with transverse extensions 27 of a pusher rod 27 that extends through the car dash within convenient reach of the motorman. The rod 27 connects with the upper cross bar of the buffer frame 22 and it has a lug 29 for engaging with a detent 28 on the inside of the car dash, which detent is swung down when it is desired to hold the buffer frame locked against movement in its axial mounts.

Pulleys 33 are mounted on the car top over which pass cables 32 that join with the upper ends of the rods 32 and with the upper ends of the arms 24 of the pincer jaws 24L.

Assmning the parts to be in the elevated or folded position, and it is desired to manually operate the fender, the motorman pushes the rod 27 outwardly, which through the connections described lifts the counterbalanced or sliding frame, whose upwardly movable rods 2-31 now pull on the cables 32, and in consequence spread the pincer jaws 24, thereby releasing the hanger device 21, and the side arms 13, which being thus re leased drop to the horizontal position. By reason of their weight, the side arms and their gear connections with the shaft 2, assist the springs on the shaft 2 to rock the said shaft 2, and thereby cause the arms (3 to swing outwardly, it being understood that immediately as the said arms 6 swing outwardly, they pull the hooks 35 from the keepers 36 and thereby release the catcher platform 8, which is then shot forwardly over the roadway under the object to be caught. As the arms 13 drop down the apron 15 unwinds by gravity and falls in front of the said object, and serves to act as a safety guard for holding the object from being mangled or crushed, should the same roll forwardly, since the said apron, when engaged by the body, acts as a drag therefor The same operations of the parts are automatically effected should the object strike the buffer frame, since the top of the buffer frame will be thereby swung outwardly and pull on the cords that lift the counterbalanced frame.
