SPECIFICATION forming part oflLetters Patent No. 453,258, dated June 2, 1891.

I Application filed January 13 1891. Serial No. 377,662. (No model.)

To all whom it may concern.-

Be it known that we, ARTHUR B. HITCH- oocK and CHARLES S. GOODING, citizens of the United States, both residing at Brookline,

5 in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Fenders or Life-Guards for Railway-Oars, of which the following is a full, clear, and exact description, reference being had to the X accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view of one end of the body or frame of a street-railway car having our improved fender or life-guard applied thereto, the boarding of the platform being removed to show the parts beneath. Fig. 2 is a plan of the same. Fig. 3 is a side elevation of the same. Fig. 4 is a front. elevation of a portion of the car body or frame, the fender being removed to show its supporting mechanism. Fig. 5 is a plan of the stiffening frame or brace for the fender. Fig. 6 is a vertical section on the line a; an of Fig. 7. Fig.7 is a plan of the fender provided with additional rods forming an inside guard over the space inclosed within the sides of the fender.

Our inveption relates to fenders or lifeguards for railway-oars, and has for its object to so attach the fender to the car that it will be constantly maintained at a uniform distance from the ground, while the body of the car will be free to rock or tilt longitudinally without imparting any motion to said 3 5 fender.

To this end our invention consists in a fender supported by longitudinal rock-shafts having their bearings on the under side of the car-body, said shafts being provided at their outer ends with crank-arms connected with the fender, and at their inner ends with similar arms connected with a portion of the truck having no vertical motion, whereby, while the fender is constantly maintained at a uniform distance from the ground, the body of the car will be free to rock or oscillate in the direction of its length independently of said fender, as hereinafter set forth.

Our invention also consists in certain novel combinations of parts and details 'of construction, as hereinafter set forth and specifically claimed.

In the said drawings, A represents the front portion of the body or frame of a railway-car.

B denotes a transverse bar, which is rigidly secured to and forms a part of the car-truck 0, Figs. 1 and 3, which has no vertical motion, and consequently the said bar will remain constantly at a uniform distance from the ground independently of the longitudinal rocking motion of thecar-body on its springs. This bar B in electric cars is arranged near the ground in front of the motor, and is termed the motor-guard.

In suitable bearings 11 Z), secured to the under side of the frame A are hung two longitudinal rock-shafts D D, each provided at their opposite ends with crank-arms e f. The inner crank arms e e are each jointed at g to a short vertical rod or link h, which is securely pivoted or fastened at its lower 'endtosome portion of ,the car-truck, in the present instance to a plate 10, bolted to the bar 13, while the outer crank-arms ff are each jointed at 12 to a short vertical rod a, secured to the inner side of the fender or life-guard E by means of straps i, the fender being thus supported by the said arms and rods, with its lower edge quite close to the ground, as seen in Figs. 1 and 3.

u The fender E consists of two plates or side pieces 7a, preferably formed of metal, arranged in V form and hinged together at the front end or vertex by means of a vertical pin 1, which is made removable in order to allow the plates 70 7a to be lapped or folded one upon the other out of the way, as seen. in dotted lines in Fig. 2, when the fender is not required for usc'as, for instance, when the to receive the pin when the two plates are folded together, as shown. The plates 7.17., when disconnected by the withdrawal of the pin Z, are free to swing in a horizontal plane upon their vertical supporting-rods a, as is necessary to permit of their being folded upon each other, as shown. As the fender is secured to and supported by the outer crank-arms f f of the shafts D ro D, which are provided at their inner ends with crank-arms c e, rigidly connected with the bar B or other portion of the car-truck which has no vertical motion, it will be obvious that the fender E will always be maintained at a fixed or unvarying distance from the ground, as it will be impossible for the outer ends of the crank-arms to be raised 01' lowered so long as they remain connected with the stationary bar 13 or other portion of the car-truck which has no vertical motion. The canbody, however, with the bearings b b, is free to rock or oscillate longitudinally, such motion causing the shafts D D to rise and fall and turn within their bearings Z) I) without varying the distance of the outer ends of the crank-arms e f from the ground, and in this manner we are enabled to support the fender at all times close to and at the same distance from the ground independently of the longitudinal rocking or tilting motion of the car, a desideratum hitherto unattained. The Variation in the amount of longitudinal rocking or tilting motion of the car-body at different distances from the center of its 3 5 length is compensated for by making theouter crank-arms f proportionately longer than the inner crank-arms e, as seen in Figs. 1 and 4, thus equalizing the movement and preventing the parts from being subjected to strain.

As the crank-arms ff and shafts D D merely serve to support the fender E, it becomes necessary to provide means for stiffening the same to enable it to resist any longitudinal thrust produced by contact with a person 5 or body on the track. Hence we employ a frame H. (Seen detached in Fig. 5.) This frame consists of two horizontally-arranged rods n a, suitably secured at their inner ends to the bar 13 and having their front ends con- 5o neeted by a horizontal transverse bar or rod 1). The outer ends 20 of the rods n it pass through eyes (1 at the lower ends of the vertical fender-supporting rods a a, as seen in Figs. 1 and 4, where they are secured by pins '2'. These rods n n thus serve to stiffen and brace the fender against any force exerted in the direction of the length of the car, thus preventing the fender from becoming broken or injured by contact with a person or obj ectupon the track.

In order to prevent a person upon the track with whom the fender might be brought into contact from being thrown over into the space inclosed by the side pieces 70 7:,we preferably provide the fender with a guard extending over the top of this space from side to side. ()no formof such guard or protector is shown in Fig. 7, the same consisting of two crossed rods I I, the front ends of which are hooked into eyes 25, projecting from the inner sides of the plates 70 at the upper edge, while their rear ends, which are provided with slots to, embrace and are held in place by the upper ends of the vertical rods a, the slots to permitting the movement of the side plates 70 of the fender when they are folded or lapped over each other, as before described.

hat we claim as our invention, and desire to secure by Letters Patent, is

l. The combination, with a railway-car, of a fender or guard connected with the body of the car, and also with a portion of the truck having no vertical motion, through the medium of longitudinal rock-shafts provided with crank-arms at their opposite ends, the outer arms being connected with the fender and adapted to support the same, and the inner arms being connected with the said portion of the truck having no vertical motion, whereby the fender is maintained at a uniform distance from the ground independently of the longitudinal rocking or tilting motion of the car-body, substantially as set forth.

2. The combination, with a railway-car, of a tender or guard, two longitudinal rockshafts having their bearings on the under side of the car-body and provided at their outer and inner ends with crank-arms, and jointed connections between the outer crankarms and the fender and the inner crankarms and a portion of the truck having no vertical motion, substantially as set forth.

3. The combination, with a railway-car, of a fender or guard, two longitudinal rockshafts having their bearings on the under side of the ear-body and provided at their outer and inner ends with crank-arms, jointed connections between the outer crank-arms and the fender, the inner crank-arms and a portion of the cat-truck having no vertical motion, and a horizontal bracing-frame connected at its inner end with the car-truck and at its outer end with the fender and adapted to stiffen the same and resist any longitudinal thrust produced by the contact of the fender with a body or object upon the track, substantially as set forth.

at. The combination, with the fender jointed at its front end, as described, of guard-rods extending across the top of the space between its sides and having slots to permit of the folding together of the sides of the fender, substantially as set forth.

\Vitness our hands this 10th day of January, A. D. 1891.
