CAR-FENDER.
Application fi1ed. March 18, 1915.
To all whom it may concern:
Be it known that I, MARCUS L. KEIZUR, a
citizen of the United States, residing at Baker, in the county of Baker and State of Oregon, have invented a new and useful Car-Fender, of which the following is a specification.
My invention relates to fenders and has for its object to provide a yielding buffer in combination with an engine, car, or other vehicle, comprising a vertically disposed pliable net, suitably supported and positioned in advance of the face of the car, as a lifenet to protect the person struck from impact with the face of the car, and thereafter to yield, to neutralize the force of the blow.
Further objects are to so dispose the said pliable net with regard to its supports as-to also protect the person from contact with the said supports, and to so position it that on impact therewith the force of the blow will be evenly distributed over the entire body of the person struck, in the manner practised by athletes and high-divers, purely as an incident of its position.
Additional objects are to provide means whereby on impact with the said lifenet acting in the capacity of a yielding buffer, it will thereafter by the automatic application of power he moved deliberately from its vertical normal position, into its horizontal active position and incidentally will become slackened to provide a retaining carrier.
Still further objects are to provide a fender of such longitudinal dimensions, when in the carrier position, that the body of the person caught up and carried will not be cramped or doubled up. And a still further object is to provide cushioned yielding deflecting means for the protection of the person struck when standing too far out to be caught up and carried in the lifenet.
I attain these various objects by the arrangement and combination of the parts illustrated in the accompanying drawings, in which- Figure 1. is a side elevation of my invention as it appears when attached to a street car. Fig. 2. is a front view of the means by which the lifenet is adapted to yield underthe impact of a body struck, and also comprising means for applying Specification of Letters Patent.

the power. In order to avoid confusion of contiguous parts in the figure only those portions of the main frame are shown which engage directly with this member. Also the element 47 is in part broken away, the remaining portion being dropped down on its pivots to show how, from its position in side the frame of the fender, it is made to line up with the element 4E1 outside of said frame. Fig. 3. is a reduced view of my improved fender installed upon a street car,
as it appears when looking downward from the roof of the car. In this view a portion of the roof is broken away to show the position and arrangement of the automatic circuit breakers when electric power is em- .ployed in the operation of the fender. Fig.
4. is a detached view of the circuit breaking mechanism, looking toward the front of the car. Fig. 5. is a side view of the magnet, and operating mechanism in position underneath the car between the trucks, comprising the means whereby the movement of the fender is proportioned to the speed of the car, and whereby it will be operated only when the car is in motion. Fig. 6. is a top view of a portion of the frictional operating parts attached to the central sills of the car, in line with the corresponding parts shown in Fig. 8. Fig.
' 7. is a side View of the fender as it appears when folded up into its ordinary out-ofthe-way position on the rearward end of the car. Fig. 8. is a side view of the fender in its active position, showing the body of a person as it rests in the hammock-like receptacle after being struck and caught up by the fender. Figs. 9, 10 and 11, are fragmentary views showing the means of attaching the lifenet to the frame of the fender, and also the means employed for attaching cushioning means' on the rigid frame members as a protection for the lower limbs as well as the head of a very tall person, Fig. 10 being a cross section on the dotted line Y, Y, of Fig. 9.
Describing the drawings in detail, the numeral 1, represents the body of a car, to the forward corners 1 of which, at each side of the car, are secured the upright bars 2, by means of the pins 3, 4-, and intermediate fastenings.
At the downward end of each bar 2, (see Fig. 1.) is pivotally secured the extensible bracket 5, the said bracket consisting of the tion as a retaining carrier as shown in Fig. 8.
It should be noted that the relative posi tion of the upper and lower frame members are normally such that when the active position is assumed the lifenet 50 is transformed into a bowl-shaped horizontal receptacle, with a deep central depression for retaining the human body, purely as an incident of the original relationship of the said parts. It should also be noted that the independent initial depression or" the upper frame, which in its normal position should be responsive to but slight impact with the lifenet, is limited to such extent by the pin 85 of the plunger 32, as to prevent the body of the person struck from impinging on the face of the car, and further that this result will obtain throughout the entire movement from the normal to the active position.
In the construction of the frame members 13, and 20, I prefer to use steel tire channel, as shown in the cross-section Fig. 10, with the channel facing outward, and for the protection of the lower limbs, and possibly the head of a very tall person; I prefer to provide these members with a facing of thick rubber or canvas hose 13, and 20, respectively, in the application of which thereto is included the fastenings of the upper and lower borders of the lifenet 50 as follows:
In the rear side of the rubber tubing 13, is formed a plurality of slots 13', through each of which is inserted the eye 13 of the clamp bolt 13, which passes through the slot 13 and engages the rod 13 inside the tubing. The bolt 13 is then inserted through an opening in the frame 13 and secured in place by means of the nut 13 Upon each of said bolts 13 is secured a knuckle-13 and when the parts are secured in place the tubing will stand forwardly to form acushion.
Through the eyes 13 of each knuckle 13 passes a substantial rod 13 to which is secured the terminal portion 50 of each vertical strand of the lifenet, which may be made of chain links as shown in Figs. 9 and 10. These strands are held in spaced relation on the rod 13 by means of sections of tubing 18 and each of the strands of the lifenet 50 may be provided with the snap hooks 50 engaging the lin s 50 to facilitate the removal of the lower frame for repairs or for other purposes. The lifenet and other parts are attached to the upper frame 20, in the same manner but the snaphooks may be omited.
In the application of electric power in the operation of the fender, 60 represents a light cable or cord attached to the ear 20 of the depressible upper frame 20, and pass mg over the sheave guide 61, the said cord 60 after being given a turn around same is connected to the circuit breaking cam wheel or pulley 62, inside the roof of the car, (see Figs. 3, and 4). The said pulley 62 is keyed to the pin 63 which is rotatably secured in the frame bars 6%, 65, which in turn are se cured at the side of the car near the roof.
To the under side of the pulley 2 is secured by means of the pin 62, the crank 66, having the crank pin 67, which is adapted to engage the handle 68 of the circuit breaker 69, closing the circuit when the said pulley 62 is rotated.
The circuit breaker 69, is normally open, the circuit breaker 70 being normally closed, and the two are connected by the conducting wire 71, the connections being such when the circuit is closed by the rotation of the pulley 62, the current comes in from the service wire through the wire 7 2 and passes out through the wire 73 rearward to the solenoid ma net 80, entering same through the wire (3 and on energizing the said magnet said current is grounded through the wire 74 (see Fig. The mag net is rigidly secured between the sills underneath the floor of the car.
secured to the central sills 96. 96 and extending downward therefrom are the brackets 81, and in the looped portion of the clips 82 is movably secured the rockshaft 83 On the outer ends of the arms 83 of the rockshaft 83 is rotatably secured the shaft 841 by means of the clips 83 and on the said shaft 8% is keyed the friction wheel 85, having the rubber rim 86. Keyed on the outer end of the shaft 8% is the winding pulley 87 having attached thereto the light cable 88 which passing under the guide sheave 89 of the bracket 90, thence over the guide sheave 91, and thence underneath the floor of the car and over the trucks at one side ofthe kingbolt to the sheave 92 (see Fig. 1), underneath same and thence continuing as 88 secured to the ear 20 of the upper frame 20.
On the rockshaft 83, is secured the lever 93 which is rigidly braced in position on the said rockshaft by means of the braces 9%. By means of the spring 95 shown in dotted outline in Fig. 5 on the inner side of the sill 96 the said rockshaft and therewith the friction wheel is balanced at a suitable distance above the roadbed 15 and adapted to be readily depressed thereon. The connecting rod 98 is secured in the end of the core 99 by means of the pin 100, and to the top of the lever 98 by means of the pin 101, as shown in dotted outline.
The arrangement and connections of the various parts are now such that through the impact of a person with the lifenet 50 and the consequent depression of the upper frame 20, the pulley 62 will be rotated by the cord 60 closing the electric circuit and energizing the solenoid 80, forcibly drawing inward the core 99. By means of the rod 98 which connects the said core 99 with the lever 93 of the rock-shaft 83*, the outer ends of the said rockshaft are rocked downward and therewith the friction wheel engages the pavement or roadbed andis rotated thereby in the direction in which the car is traveling. As the friction wheel 85 rolls on the pavement, the winding pulley 87 keyed on the same shaft therewith, winds up a portion of the cable 83 which being connected to the upper frame 20 draws down the said rp er frame, extending the fender into its active position as shown in Fig. 8, the lower limbs of the person struck being swept forward and upward high above the pavement with the body reclining in the bowlshaped retainer, the partial inversion of the lifenet providing an effectual barrier against the possibility of rebounding therefrom. The rotation of the circuit'breaking pulley 32 continuing with the movement of the upper frame downward, the pin 67 of the crank 66 engages the handle of the circnit breaker 70, breaking the circuit and releasing the friction wheel 85 from contact with the pavement as the fender is fully extended.
Referring to Fig. 3,,it will be seen that in this position of the fender the greater portion of the weight of the person is on the upper frame 20, and as the pivotal fastening 25 of the triangular frame 22 is virtually in line and therefore on the dead center with the pivotal fastenings 3S and 4L0 of the connecting rods 39, which holds the lower frame in the extended position, the pivotal fastenings of the extensible brackets 5 being also virtually in line w'th the pivotal fastenings of the lower frame, the fender will be inclined to maintain its ac tive position after the friction wheel 85 is released.
It should be noted that the position of the lifenet in its normal position is such that yielding members 31, positioned at either side of the frame, tend to further minimize the said shock in time of accident. It should also be noted that the windin pulley 87 is made much smaller than the friction wheel 85, for this reason a deliberate movement is imparted to the fender, and the person caught up is not subjected to undue shock from this cause. It should further be noted that the swing supports 16 serve the twofold purpose of deflecting the person aside if too far out to be caught, as well as providing a yielding buffer against impact with the rigid side portions of the fender frame.
On the opposite end of the shaft 84 is keyed another winding pulley 120, (when double ender cars are used) having attached thereto the cable 121, which passes under the guide pulley 122 of the bracket 123, and thence rearward in the opposite direction'to the upper frame of the fender on the other end of the car, actuating that fender when the friction wheel 85 is depressed onto the pavement when the car is runningin that direction. wound oppositely around their respective pulleys, when one winds up, the other pays out correspondingly, the slack being taken up again when the active fender is restored to its normal position. Hence, it will be seen that a single actuating means in turn operates a fender on either end of the car, though of course circuit breakers are required for each fender.
In order that the circuit breaking pulley 62 will automatically return to its original position when the fender is restored to its normal position, I provide a tension spring 108, shown in dotted outline in Fig. 1, the rearward end being secured at any convenient point inside the car, and the forward end being secured to the tension pulley 110 by means of the cord 109, the said pulley 110 being keyed to the pin 63, the spring 108 being of sullicient strength to restore the parts to their normal position without counteracting the actuating means of the fender.
The sleeve 39 slidable on the jointed rod 39 is slidably secured to the upper half 39 by means of the pin 39, and the slot 39 the ends of the rods 39 being jointed in the center 39 of the sleeve 39 hen it is desired to fold the fender up into its out-of-the-way position the sleeve 39" is slid upward on the pin 39 allowing the parts to separate. The lower frame may then'be raised up, as shown in Fig. 7, and secured to the face of the car by any convenient means. I I
It will be understood that the form herein shown is subject to various adaptations and and 39 normally As the cables 88, and 121 are modifications to meet the requirements and limitations of the different vehicles to which it may be attached, all of which are within the spirit and principle of my invention, It
should further be stated that similar results may be obtained by the use of springs,
