EMIL M. KNOTHE, OF SEATTLE, WASHINGTON, A-SSIGNOR TO EMELINE KNOTHE, OF SEATTLE, WASHINGTON.

CAR-FENDER.

To all whom t may concern: f

Be it known that I, EMIL M. KNOTHE, a citizen of the United States of America, and a resident of the city of Seattle, in the county ofKing and State of Washington, have invented certain new and useful Improvements in Car-Fenders, of which the following is a specification.

My invention relates to fenders for cars or vehicles and more particularly to that type which is automatic in operation.

The primary aim is to provide a fender of simple and durable construction wherein the operation throughout is eflicient.

Further objects will be set forth in the following specification to which reference is had, in connection with the accompanying drawings, for a full understanding of the invention, and those features of construction, arrangements and combinations of parts on which I desire protection will be defined in a succinct manner in the appended claims.

In the drawings, wherein like characters of reference are used to designate corresponding parts throughout the several views, Figure 1 is a longitudinal fragmentary section of a car embodyingy my invention and showing two raised positions of my fender in dotted lines. Fig. 2 is a similar view wherein the fender has been Amoved to trip the operating mechanism. Fig. 3 is a horizontal section taken below the car platform and having portions broken away for the sake of clearness, and Fig. 4 is a fragmentary front elevation of the car with my invention applied, the fender apron and guard being removed and other portions being omitted.

Referring more particularly to the drawings, the fender apron 1 and guard 2 are supported and suspended by hangers 3 from brackets 4 fixed to the front of the car 5. The fender apron may be folded up against the guard 2 and both, with hangers 3, swung up to the dot and dash lined position in Fig. 1, whereby access to the draft bar may be obtained conveniently. In their normal position the hangers are supported on pins 6 for swinging downwardly in a receding manner toward the track, while braces 7 yieldingly hold the fender in its forward position.

Each brace 7 comprises a tubular section 8 pivoted to the lower end portion of the Specication of Letters Patent.

Application filed October 29,1914. Serial No. 869,250.

adjacent hanger;- a section 9 pivoted to the car and slidable within the tubular section;

and a coiled spring 10 normally tending to maintain the brace extended and thereby hold the fender in its normal position.

The fender hangers are joined by a transverse bar 11 from which extends rearwardly a link 12 having its rear terminal engaged in a head 13 for limited sliding movement. A lever 14, supported between its ends, as at 15, for swinging, has one terminal pivotally connected to the head 13 and its opposite end portion similarly joined to a piston rod 16. The piston of the rod 16 operates under fluid pressure in the cylinder 17 the limit of movement of said rod being determined by a nut 18, which is connected for movement therewith by a threaded rod 19, abutting the stop 20 fixed to the cylinder.

Fluid is admitted to the cylinder 17 from a suitable source of supply, such as that used for the brake system, through a system of pipes 21, a valve 22 being included in said pipe system to control the flow of fluid. To

vrender the operation automatic, valve 22 is each tripper normally bears against a furcated arm 27 of the rock shaft 28 which latter is mounted for oscillatory movement and provided with a pull arm 29 joined to the lever 30, of valve 22, by a yieldable connection consisting of a spring 31 and a link 32.

Briefly, the operation is as follows: The fender, upon striking an obstruction, swings rearwardly against the tension of the springs 10 moving the trippers 24 to rock the shaft 28 and consequently open the valve 22.. Upon rocking the shaft 28, the trippers ride off the arms 27 between their furcations which support the trippers (see dotted position in Fig. 2). Should the travel of the pull arm 29 be in excess of the movement granted the valve lever 30, the yeildable connection therebetween lcompensates therefor. During the initial movement of the fender, the link 12 slides in the head 13 to eliminate the additional energy necessary to move also the piston in cylinder 17, and thereby renders the fender more sensitive and practical. As soon as the fluid is admitted to the cylinder 17, lever 14 is swung carrying with it the head 13 until a rigid connection with the link 12 is obtained, whereupon the fender is dropped or swung downwardly as shown in dotted lines in Fig. 2.

It is not my intention to limit my invention to the detailed description above given, except as the prior art may require, such description being set forth to give a lucid understanding of the preferred embodiment of the invention.

Having thus, described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, 1s:--

1. A movable fender, a yieldable support therefor, a tripping mechanism therefor comprising a pivoted arm and a rod movable with the fender and having operative connection with said arm, and means controlled by said arm to move the fender.

2. A movable fender, a yieldable support therefor, a tripping mechanism therefor comprising a pivoted arm and a rod secured to the fender and having operative connection with said arm, and means controlled by said arm to move the fender.

8. A movable fender, a yieldable support therefor, a tripping mechanism therefor comprising a pivoted bifurcated arm, and a rod secured to the fender and having operative connection with said arm below the bifurcated portion thereof, said rod being adapted to enter said bifurcation after its initial effort, and means controlled by said arm to move the fender.

4. A movable fender, a yieldable support therefor, a tripping mechanism therefor comprising a pivoted arm and a rod movable with the fender and having operative connection with said arm, means controlled by said arm to move the fender, and a yieldable connection between said means and said arm.

5. A movable fender, a yieldable support therefor, a tripping mechanism therefor comprising a pivoted arm and a rod movable with the fender and having operative connection with said arm, means controlled by said arm for moving the fender, and manually operated means for controlling said first means.

6. A pivoted fender, a telescoping springheld support therefor, a transverse shaft, a bifurcated arm secured thereon, a rod secured to the fender, a guide for said rod, the inner end of said rod bearing against said arm below the bifurcation, and adapted to enter said bifurcation after its initial effort, a second arm secured upon said shaft and means connected with said second arm for swinging said fender downward and back.

7. A pivoted fender, a telescoping, spring. held support therefor, a transverse shaft, a bifurcated arm secured thereon, a rod secured to the fender, a guide for said rod, the inner end of said rod bearing against said arm below the bifurcation, and adapted to enter the said bifurcation after its initial effort, a second arm secured upon said shaft, means for swinging said fender downward and back, and a yieldable connection between said means and said second arm.

Signed at Seattle, Washington this 20th day of October 1914.
