SPECIFICATION forming part of Letters Patent No. 545,186, dated August 27, 1895,

Application filed April 23, 1895, Serial No, 546,809. tNo model.)

To @ZZ whom it may concern: y

.Be it known that l, CHARLES S. ANDREWS, a citizen of the United States, residing at the city, county, and State of New York, have made certain new and useful Improvements in Car-Fenders, of which the following is a specification.

My invention relates to devices supported in front of the platform of the car, which are designed to safely piek up and carry human beings, as well as other objects, and prevent injury thereto.

My invention consists in the combination of parts, and in the construction hereinafter described, and further pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a side elevation of a car with my improved fender attached, diagramrnatically illustrating the action of the fender; Fig. 2, an enlarged front elevation of the fender secured in place; Fig. 3, a side elevation of Fig. 2, partly in section, taken on the line X X, Fig. 2; Fig. 4f, a like elevation showing the position ot' the fender when folded and inoperative. Fig. 5 is an enlarged sectional elevation of the front portion of the fender side bars; Figs. 6 and 7, side and front elevations, respectively, of the counter-roller and its support in the side bar. Fig. S is a sectional elevation, enlarged, of the sprocketwheel hanger and detent; Fig. 9, an enlarged fragmentary elevation of the netting and means for hingingfthe portions together, and Fig. lO a side elevation thereof.

Similar numerals of reference indicate corresponding parts throughout the several views.

The object of my invention being to provide an efioient fender I construct the same substantially in the manner hereinafter described.

At 1 in the drawings is one of the longitudinal sills of a car to which is secured an arm or casting 2, provided with side flanges 3, which embrace the sill 1, and to which said arm is secured by bolts 4, as shown in Figs. 2 and 3, respectively. The flanges 3 form a bifuroated end for the arm 2, which flanges extend a considerable distance rearwardly, the end of the sill abutting against the inner end of the bifurcations, the length of theside plates 3 giving a firm bearing ou the sill for the support of the arm 2 and its appendages. I preferably cast this arm E. hollow, as shown, so as to preserve strength and lightness, and give to it a downward curve or bend, and at the end of the samethe arin is provided with` 'a longitudinal slot or opening 5, and in an aperture in each side thereof is formed bearings G for a cross-shaft 7, hereinafter described. These arms are located, there being two of them, at the desired positions in relation to the platform and secured to the end of the sills, as shown in Fig. 2.

To the shaft 7 is hinged a swinging arm S, preferably' cast hollow, and which is provided with an extension 9, (see Fig. 11,) so as to give a firm hearing from the same on the shaft 7, the swinging arm heilig adapted to be lowered into the position shown in Fig. 3, in which position it is adapted to operatively engage obstructions on the track, a lip 10 on the forward part of the arm 2 taking the strain of the weight of the hinged arm S and limiting its downward movement. Each of the arms 2 are provided with the hinged arms 8, and l shall hereinafter term the arms 2 and 8 as the side bars of the fender.

The forward portion of the arm 8 is provided witha recess or guideway 11, formed in the upwardly-curved portion 12 of the arm 8, the guideway following the curve of this portion of the arm, and within the guideway 11 is located a spiral spring 13, which abuts at its forward end against a bearing or follower 14. This follower is designed to act as a bearing for a transverse shaft 15, which extends between the two side bars and out from each side thereof, and fixed ly supports thereon the wooden roller 16, having the outside supplemental extensions 17, lying beyond the side bars and extending outbeyond the track 18, as shown in Fig. 2.

The end of the arm S is provided with a rounded cap 19, designed to act as a bearing for the shaft 15 in its position of furthermost projection, as well as to restrain and limit the outward movement of said shaft under the influence of the spring 13, the cap 19 having lips 20 fitting over the end 12 of the arm S,to which end the lips 2O are secured by bolts 2l in any suitable way. The object of this construction is to provide means which, by reason IDO- of the downward bend of the arms 2 and 3, brings the end 12 low enough to strike a body at such a point as will throw the same over upon the fender, the roller 1.6 at the same time rotating and forcing its shaft inwardly against the stress of the spring, and downwardly, so as to follow the natural line of movement of the fall of the body, and then upwardly in the direction of the movement of the body, which is then contrary to the movementofthe car, the roller 16 rotating inwardly and moving the body toward the net of the fender. Thus the action of the rolleris downward and inwardly against the spring, to ease the Shock of striking, then upward and forward to lift the body, the roller rotating to progress the body rearward onto the net. The curved portion 12 also provides means for allowing the arms to readily ride over such temporary or fixed obstructions as it may not be necessary to catch upon the fender, and the rounded cap permits the body to ride over it without obstruction.

To further propel the body toward the netting I form in the arms 8 a further bearing fora shaft 22, which has an extension equal to the shaft 15 between the side bars of the fender and outside of them, and which supports a roller 23, preferably of wood, larger in diameter than the roller 16, and which receives the bodyl and further enables its easy progress from the roller 16 to the netting to be readily accomplished.

The netting which is designed to finally receive the body is pivotally secured to the arm 8 at the rear of the roller 23, and is formed of three sections hinged together, so as not onlyto form or provide a suitable receptacle for the body, but to enable it to be stowed behind the hinged portion of the fender when the same is thrown back, as shown in Fig. 3, the netting being provided with a connterpoise arrangement involving two elements, aweight anda spring, the weight acting to support the netting in its position of projection and counterbalance the same, the spring acting to resiliently resist the shock given to the netting when the body strikes it, with which part is combined a detent to prevent the spring from drawing orstraighteningout the netting after the body has struck the same and moved it rearward, as shown in Fig. 3, and from being again straightened out by the spring, and thus throwing the body out of it.

I construct my netting as follows: Extending between the arms 8 is a rod 24, (shown in dotted lines, Fig. 2,) to the ends of which are secured articulated side bars 25, comprising the bars 26 27 28, hinged togetherat 29 30 by bars or rods 31 32, and secured at the top transversely by another' bar or rod 33. I prefer that the side bars 25 should be stift', while the bars 3l 32 33 can be of lighter material, such as used in the construction of heavy wire-netting, the side bars 25 being intended to stiften the netting. Intermediate of the side bars 5 is another centrally-located bar 25, concrumed portions being united to their hinging v bars or rods, as shown in Fig. 9, where it will be seen that the wires 34 of the section A are looped around one of the cross bars or rods 31, and the wires 35 of the section B looped around the same rod in the reverse direction to form a hinged connection. Thus, in the presence of undue shock, the netting will be moved inwardly and by means of its hinged connection assume the form of a receptacle, as shown in- Fig. 3 in double dotted lines, whchwil receive and Vhold the body.

To support the screen in the manner hereinbefore described and to resiliently resist the shock when a body strikes it and moves it forcibly inward, I employ the following construction: To the dashboard 30 of the car or any other appropriate place I secure pintles or eye-hooks 37 and pivotally support from these hooks bifurcated hangers 3S, between the arms 39 of which lies a sprocket-wheel 40, havingsuitable sprocket-teeth, over which is adapted to run a sprocket-chain 41, engaging the cross-rod 33 of the netting at one end and thence running downwardly, and at the other end engaging a cap 42, to which is secured a weight 43 and one end of a spiral spring 44, the spring embracing the weight, the lower end of the spring being fixedly secured to a pin 45, in its turn secured to the dashboard, the spring being Wide enough to permit the weight 43 to move up and down within it. To the flat face 46 of the hanger 38 is secured one end of a spring 47 at 48, the other end being provided with a finger 49,which is adapted to bear against the sprocket teeth 50 of the Sprocket-wheel 40, which freely rotates upon a shaft 51 journaled in the arms 39 of the hanger, this spring acting as a detent, which permits the sprocket-teeth to ride past it in the direction of the arrow, Fig. 8, but acting as a dog to restrain the reverse movement of the sprocket wheel and chain. Thus when the body strikes the netting the force of the blow moves the sections of the netting into the angular relation shown in Fig. 3, whereby a receptacle is formed for the reception of the body, which movement of the parts lowers the cross-rod 33 and by the sprocket-chain 4l lifts the cap 42 against the stress of the spring 44, thus resiliently resisting the blow. At the same time the dog 47 rides over the sprocketteeth of the sprocket-wheel, and when the body has come to rest the dog engages the teeth of the sprocket-Wheel in its tendency to move in the reverse direction under the stress of the spring and restrains such movement. Thereafter, when desired, the dog can be freed from engagement with the teeth of the sprock- IOE et-wheel and the screen or nett-ing brought back into its elevated position again, when the weight 44, which had also in a measure acted to resist the blow or impact of the body on the screen, suspends the netting in its projected position by reason of its downward pull on the sprocket-chain Lie, taking this stress from oft the spring.

As shown, I prefer to use three sets of this particular device, which distributes the strain equally over all the netting and allows the use of three small weights and springs, where otherwise one large one would be necessary, thus enabling the proper distribution of resistence to be made.

In order to provide against the end of the side bars from striking the ground during the oscillation of the car, I provide what I call a counter-roller l, journaled on a shaft 52, having bearings in the bifurcated arms 53 of a suitable stem or standard 54,'which extends up through an aperture formed in the arm S and secured therein by a lock-nut 55 at the top, the stem having an annular shoulder 56 lying within an annular recess formed about the aperture through which said stem extends, and which forms an interior bearing for said stem, the exterior of the arms having a bearing-plate 57 to form a rub or wearing surface for the arm 53. Thus should the arms S during undue oscillation of the car strike the ground the roller will receive the force of the blow, and during the turning of sharp curves should this occur the fender will be enabled to make a rolling contact on the roadbed, and thus relieve the joint of the arms 2 and S from the strain.

From the foregoing it will be apparent that many changes and modifications can be made in the foregoing structure without departing from the spirit of my invention.
