CAR-FENDER.

SPECIFICATION forming part of Letters Patent No. 637,725, dated November 21, 1899. Application filed September 7l 1889. Serial No. 729,750. 110 model.)

T0 all whom t ina/y concern:

Beit known that we, JOSEPH WJ A. GARDAM and FOSTER J. HULL, citizens of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Car-Fenders, of which the following is a specification.

Our invention consists in improvements in car-fenders, and has particularly forits Object to improve automatic fenders of the type shown in the patents granted to Obe. Cullison, No. 536,853, dated April 2, 1895, and No. 625,834, dated May 30, 1899, though it should be understood that our invention is not limited in its useful applications to 'fenders of that particular type and that one or another or all of the features of such invention are applicable to car-fenders of many dierent kinds, as will be understood by those Skilled in the art.

In the drawings, Figure 1 is a side elevation of our improvements applied to a at-car. Fig. 2 is a top plan view of the fender devices at one side of the car, the car-liooring being removed. Fig. 3 is a sectional elevation of the fender applied to a car, the view being on a larger scale than Figs. 1 and 2 and being in two parts, the lower part being a continuation of the upper part. Fig. 4 is a vertical section taken on the line 4 4 of Fig. 1. Figs. 5, 6, and 8 are vertical sectional views'taken, respectively, on the lines 5 5, 6 6, and 8 8 of Fig. 1. Fig. 7 is a sectional view taken on the line '7 of Fig. 8. Fig. 9 is atop-plan View of the horizontal portion of the fender proper detached. l Fig. 10 is a perspective view of a portion of the mechanism for retracting the fender. Fig. 11 shows in perspective the several parts which together form the bearingsupports for the horizontal portion of the fender, the parts being separated from one another. the line 12, Fig. 2.

In the drawings, A represents the body of' the car; E, one of the truck-frames thereof;

F, the springs between the truck-frame and the car-body; B, one ofthe wheels; H, the

car-platform, and C the dashboard,these parts being of any usual or preferred construction.

Our fender ispreferably-supported directly from the truck instead of being suspended Fig. 12 is a sectional view taken on.

from the car-body. We therefore prefer to construct the truck with forward-extending arms c, to which are secured brackets 10, in which are mounted the fender-supporting bars 12, which bars are preferably channelshaped and constitute waysin which are become bent or to get out of proper alinement under any conditions of practical or ordinary use, with the result that the sliding bars 2 travel freely in the supporting-bars. The

supporting channel-bars 12 are connected at their forward ends by a tie-rod 20, the ends of which are supported in brackets or castings 58, which are in turn bolted or'otherwise secured to the bars 12, as represented in detail in Fig. 6. The castings 58 are extended below the sliding bars 2 and arranged to constitute bearings for the horizontally-disposed antifriction-rollers 19, upon which such Sliding bars bear.

30 30 indicate vertically-disposed antifriction-rollers arranged to bear against the vertical sides or faces of the sliding bars 2 and operating to hold themrin the ways in the channel-bars 12 and at the same time permit them to move therein without undue friction. The rear ends of the sliding bars are connected by a tie-rod14, and 31 indicate antifriction-rollers journaled upon the tie-rod 14 and bearing against the ways of the channelbars. They operate to confine the sliding bars 2 in the channels or ways of the supporting-bars 12 and permit them to move therein without undue friction.

The vertically-disposed webs of the channel-bars are slotted throughout a portion of their length, as indicated at 16, and lugs 17 on the sliding bars 2 extend outward through IOO these slots. Spring-buers 170v are prefer` ably arranged in the forwardl portions of the slots to take up the shock incident to the a'utomatic forward movement of the fender.

21 indicates a pivoted hook or latch adapted to engage with one of the lugs 17 of the sliding bar and to operate to retain the sliding bars and the fender in ytheir rearward posi-` tion, as when the cars are stored inthe barn. It will be understood that there may be one of these `hooks orv latches on each side of the car, if found desirable Y The sliding bars 2, which carry the fender proper, are connected at or near their forward ends by the tie-rod 23. Instead of attaching this tie-rod directly to the sliding bars we prefer to mount it in castings 52,

the fender proper is made easily removable from its supporting and operating parts, it

`being only necessary t-o loosen the pins or bolts 55 and remove the block 54, after which fthe fender may be freely removed.

The fender proper consists, preferably, of the side bars 5 and cross-bars 3 and 4, of angle-iron, uniting them. The horizontal netting 61 is supported between these

bars

3, 4,

and 5, as represented in Figs. 2 and 9, and isl preferably entirely independent of the upward-extending part of the netting 62. This latter is preferably connected at its lower end `to the cross or tie rod 23 and extends upward in front of the forward end of the platform H, where it may be secured in any desired way. By making the fender-netting of two independently-mounted parts we are enabled lto remove the fender properl and the horizontal netting without disturbing the upward-extending portion v62 of` the netting. The side bars 5 of the fender proper are ex- I Vtended rearward beyond the pivots or trunnions 53 to constitute trip-arms 24. When .the fender is retracted, as indicated in Figs.

l and 3, the ends of these trip-arms are arranged directly below the spring-catches 18, which are arranged to engage with lugs or projections 33 on the Isliding bars and hold the fender in its retracted or rearward position.

in the hereinbefore-referred-to Cullison patents, the manner in which they operate as an automatic trip when the fender meets an obstruction need not be described herein.

It is desirable that the spring force f the catches 18 should be capable of adjustment or variation, and` to permit of this we provide As these features are fully described l the springs 35, which are arranged to bear upon the spring-catches 18 and the adj Listingnuts 34, by which the tension of the springs 35 may be Varied. These spring adjusting parts are mounted upon the supporting-bars 12, upon which are also mounted the springcatches 18. 1

It is desirable that the fender should be not only automatic in its operations, but that it should be also so under the control of the motorman that he can cause' it to be projected or shot forward at will. To permit this, we have devised means whereby lthe fender may be released from the holding-catches 18 at the pleasure of the motorman. 36indicates alever arranged in convenient position to be operated by the motorman when in his place uponthe platform H. This leveris suitably connected, as by means of a chain or other exible connection 38, with a lever 39, secured to a rock-shaft 40, to which are secured cams or short arms 41, adapted to engage with the spring-catches 18 and so move them as to release the sliding bars and fender and permit them to be automatically projected.

It will be understood that when the fender is tripped and projected forward its forward end drops toward the track, the fender rocking'slightly upon the trunnions 53. It has v been found desirable toprovide means whereby the position to which the forward end of the fender drops withreference to nearness to the track may be determined. W'e have devised novel means for thus controlling the movement of ,the fender toward the track. They consist of eccentric-shaped stops 37, bugs. 7 and 8, which are bolted to the crossrod 26. It will be seen by reference to Fig. 1 that when the forward end of the fender drops the portions of the side bars 5 in rear of i the trunnions 53 come into engagement with these stops, and the fender is thereby held from further downward movement. The stops 37 can `be adjusted to dierent positions and secured, as will be understood.

56 represents a projection carried by the casting 52 and arranged opposite the stop 37.

It serves as a stop to limit the extent to which the fender may be thrown upward at its forward end. It will be understood that in practice the

stops

37 and 56 will be duplicated at the opposite sides of the car, as indeed are most of the parts of the fender which have thus far been described.

In the before-mentioned patent, No.625,834, the springs which operate to project the fender are represented as being connected directly with some sliding part of the fender mechanism. This arrangement is disadvantageous in that it subjects the spring to too great stretch or distention, the vstretch of the spring being equal to the full movement of the fender. It is better to use a more pow-V erful spring and have it subjected to less longitudinal distention than wouldbe incident in a construction like that shown'in the said patent, as the danger of breakage will thereby IIO IZO

www, .nwwwws be lessened and the effectiveness of the .springs prolonged. Such an arrangement we have invented. 25 indicates the spring for projecting the fender, and there may be one or more such springs, as may be required. It is secured at one end to some stationary part of the car, such as the bracket 26, and at the other end is secured to a iioating pulley 27, through which is threaded a cable 28. One end of this cable is securedto the car-body, as at 29, and the ot'her end, after passing the floating pulley. 27 and a second stationary pulley 32, is attached to some sliding part of the fender mechanism, as to the tie-bar 14. It will be readily seen that b y means of a construction such as'that described the movement of the end of the spring which is secured to the floating pulley is but one-half as great in extent as are the movements of the sliding parts of the fender. The rear or stationary end of the spring 25 is preferably secured to an eyebolt 60, which eyebolt is adjustably mounted in the bracket 26, by which means the tension of the spring may be increased or decreased, as required.

W'e have also invented improved means Vwhereby the fender may be automatically re- 42 indicates a iiexible connection, such a-s a chain or rope, secured at one end to an upward-extending arm or bracket 43, carried by one of the side bars of the fender proper and extending thence backward to a suitable shaft 44, around which it' is wound. This shaft is provided with friction rolls or pulleys 51, adapted to be moved into engagement With the car-wheels B, by which they will be turned in order to wind the rope or chain 42 upon the shaft 44.

45 indicates an operating-lever arranged adjacent to the platform H in convenient position to be operated by the motorman and having its lower end 46 connected by a chain or other suitable connection 47 with a lever 4S, keyed to a rock-shaft 49.' 50 indicates a toggle-lever connection between the shaft 49 and the supports for the shaft 44, carrying the friction-pulleys 5l. It will be understood that whenever the motorman moves the lever 45 so as to force the friction wheels or pulleys 5l into engagement with the car-wheels the shaft 44 will be turned and the flexible connection 42 wound thereon and the fender retracted. The fender-retracting devices which have just been described are preferably duplicated on opposite sides of the car.

The upward-extending arms or brackets 43, to which the iiexible connections 42 are secured, are so arranged that when there is a rearward pull upon the said iiexible connection the forward end of the fender will be raised before the fender as a whole is retracted.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
