EDWIN LQHARRIMAN, or E'INA MILLS, cA IFonNIA.

To all whom it may concern:

Be it known that I, EDWIN L. HARRIMAN, a citizen of the United States, residing at Etna Mills, in the county of Siskiyou, State of California, have invented certain new and useful Improvements in Tram- Car Fenders; and I do hereby declare the fol-- lowing 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.

This invention relates to improvements in car fenders and more particularly to that type of fender carried from the front or dash-board of a tram-car.

One object of the invention is the provision of a fender which will fold upwardly after striking an object, whereby the object will not be flung aside but will be cradled by the fender.

Another object is the provision of a means fortripping the fender and causing it to move from one position to-anotlier after striking an object.

With these and other objects in view as will more fully hereinafter appear, the present invention consists-in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from thespirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part'of the specification :Figure 1 is a plan view of the device. Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1 and showing the position of the parts before striking an object. Fig. 3 is a similar, view position of the parts after striking an objec Similar numerals of reference are employed to designate corresponding parts throughout.

The main or body portion of the fender consists of a pair of side bars or sills 5 and 6. These members are preferably of metal, and substantially right-angular in contour. The sills are so arranged that one of their sides will extend vertically upward while the opposite side will extend forward and outward. The upper end portions of the Specification of Letters Patent.

TEAM-CAR FENDER.

Application filed October 6, 1909. Serial No. 521,284.

sills are connected by a cross piece 7 and the intermediate portions by a similar cross piece 8. The distance between the sills will correspond, approximately, to the width of an ordinary tram-car and the space between the sills may be covered with wire or hemp netting, secured to the cross pieces 7 and 8.

The forward end portions of the sills 5 and 6 are, on their opposed inner faces, provided with the vertically cut out portions 9 and '10 and pivotally supported from these porbetween the sides 12 and 13 and cross pieces 14. and 15 may be covered with wire or hemp netting. In order that the opposite outer faces of the sides 12 and 13 may be flush with the outer sides of the sills 5 and 6, the said sides are, on their outer faces, and adjacent their inner ends provided with vertically cut out portions 16 and 17, whichcorrespond in length and depth to the vertically cut out portions 9 and 10 and in advance of the vertically out out portions 16 and 17 are further cut away as shown at 18 and 19, thus permitting the inner extremities of the sides 12 and 13 to extend inwardly from the vertically cut out portions 9 and 10 of the sills 5 and 6 andbear on the op posed inner faces of said sills 5 and 6.

The swinging frame is pivotally supported from the side sills 5 and 6 by means of pivot bolts 20 extending through the vertically cut out portions of the sills and those of the sides 12 and 13.

In order that the swinging frame may fold upwardly and inwardly after striking an object a pair of helical springs are employed, the ends of which are fixed to the inner ends of the sides 12 and 13 of the swinging frame and at points adjacent the middle and on the outer faces of the sills 5 and 6. When the swinging frame is in its normal position, that is extending con tinuously in advance of the forward side portions of the sills 5 and 6, the springs 21 and 22 will be tensioned and in order to maintain the swinging frame in this position against the action of the springs 21 and 22 the following construction is employed By referring to the drawings it will be seen that pivoted on the inner faces of the sills 5 and 6 between the inner sides of the swinging frame and lower-most cross piece 8 of the main frame are the intermediate port-ions of a pair of dogs 23 and 24. These dogs are so positioned that their forward ends will bear on the lower sides and adjacent the inner edges of the sides 12 and 13 of the swinging frame. The opposite ends of these dogs are bent downwardly and engaged beneath the lower edges of plates 26 and 27 secured to the ends of the cross bar 25. Referring to Fig. 2 of the drawings it will be seen that the rotative tendency of the frame 11 engendered by the helical springs 21 and 22 is transmitted through the dogs 23 and 2% into a lifting tendency of the cross bar 25. This is resisted by guide bolts 30 carried by the opposed inner faces of the sills 5 and 6 and passing through elongated slots 29 in the plates 26 and 27. In the normal position of the fender, being that shown in Fig. 2, the swinging frame is thus locked against upward movement by the dogs as described. lVhen an object is caught in the fender the weight of the object will depress the bar 25, the plates moving downwardly and depressing the left hand or inner ends of the dogs. This motion is transmitted to the swinging frame and causes the latter to pivot downwardly against the tension of the springs until the points of the sides 12 and 13 disengage from the ends of the dogs. The springs then draw up the frame into the position shown in Fig. 3 and the object which tripped the fender is safely cradled therein.

It will be seen that I have provided a device which is simple in construction and comparatively easy to manufacture having few parts and these so arranged that the danger of derangement will be reduced to a minimum.

What is claimed as new, is

1. In a car fender, the combination of a main frame, a swinging frame at the front end of the main frame and connected thereto for up and down movement, springs to raise the swinging frame, a cross bar in the rear of the swinging frame and having plates on its ends slidably connected to the sides of the main frame for vertical movement, and dogs pivotably mounted on the main frame and normally engaging the lower edges of the said plates and the rear portion of the swinging frame to normally hold the latter in forwardly extended position.

2. In a car fender the combination of a main frame, a swinging frame at the front end of the main frame connected thereto for up and down movement, springs to raise the swinging frame, a cross bar in the rear of the swinging frame and having plates on its ends, said plates being provided with elongated vertical slots, studs secured to said main frame and engaging the slots in said plates, and dogs pivotably mounted on said main frame, one end of each dog engaging beneath the lower edge of one of 'said plates and the other end of said dog engaging beneath a side member of said swinging frame, whereby said frame will be normally locked in the extended position by said dogs but will be released therefrom by the tilting of said dogs resulting from a depression of said cross bar.

In testimony whereof, I affix my signature, in presence of two witnesses.
