To all whom `zit may concern:

Be it known that I, RANDOLPH C. Lorano?,

State of Massachusetts, have invented a new and useful Improvement in Street-Car Fenders, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

My invention relates to improvements in street car fenders and has for its object the prevention of fatal injuries to persons who maybe upon the track and exposed to the danger of being run over and crushed by a moving car.

In the accompanying drawings, Figure l. is a perspective illustration of myinvention applied to the platform kot' a car. Fig. 2. is a ver- Fig. 1, and as viewed from the left of said line, and showing the attachment in its advanced position in front of the car. Fig. 3. is a like section showing the attachment ref` tracted and drawn under the platform as when following the car. Fig. 4.-. is a crosssection taken as on line y y, Fig. l, and as viewed from the right of said line.

The following is a description of the method of applying my said invention as illustrated in the drawings, but the same may be varied in details of construction, and must necessarily be, to some extent, to practically adapt it to the varying styles of cars to which it is applicable. l

To the frame work A of the car platform and beneath the locringthereot are secured, manner, two horizontal side bars A and A", having therein longitudinal grooves B `and B. These bars, being firmly attached to the` frame work, securely uphold the sliding cross-bar C, the ends I) and D of y which are supported by, and slide backward pose which will be stated. To bar C is attached the swivel-frame E, hung by a central bolt E to bar C. The pendent sides of the swivel-frame support side bars F and F by means of a rod G extended through said parts, so that the bars rock on the ends thereof. Bars F and F carry a shaft H upon which are secured tivo trucks I and I', and a roll .i arn ranged to be turned in the outer ends of the sain 110,488,051. (no man.)

y bars. Upon the inner face of truck I is secured a gear K, and upon roll .I is a smaller gear L which is arranged to be engaged and turned by gear K to revolve the roll which is raised slightly above kthe rails L', L2, on which the car moves. Truck I is turned by frictional contact with the rail, and through thev gears mentioned imparts a reverse motion to the roll J, so that the top of the rollturns toward the car, 'which motion, as before stated, tends to prevent a body from passing under the guard or fender, and to raise and cast the body up over the roll onto the safety net J secured to the fender backl of the roll, so' as to safely uphold and Vcarry abody cast thereon.

Said gearing may be so constructed as to increase or diminish the relative speed of the roll to such extent as may be found to be most advantageous in practical use. And the roll may be covered with rubber, felt, or any other suitable material to renderthe saine somewhat soft and yielding, and to increase its effectiveness in adhering to, and picking up and rolling a bodyon to the safety net or platform immediately behind the roll. A spring M, is attachedk at one end to each of the bars yF and F at the rear ends thereof, While the opposite ends of the springs are attached to arms N, which extend backward from the sides of frame E and constitute a part of the same. By this means the frictional contact of trucks I and I with their rails may be increased or diminished accordin g to the contractile force of the springs employed. The springs also constitute an elastic connection which allows the trucks to yield to any inequalities in the surface of the track over which they roll, and to accommodate themselves to any rocking motion of the car occasioned by such inequalities. And the horizontal swivel movement of frame E adapts the fender to readily follow any curves in the track Withoutcrampiug and interfering With the easy progress of the car around the same. The trucks and gears are covered by cases P and P which keep out dirt and guard them against coming in contact with any object. When the fender is advanced by sliding bar C forward'in grooves B, in front of the-car, as shown in Figs. l and 2,and ready for practical use, it may be secured in such position by stop pins R dropped through holes in the sides of the platform of the car and into holes IOO 'Y Y yward movement ofthe car causes the trucks I and l to roll upon their tracks, and, thus in the bar C, as shown; and may also be securedin like manner when retracted, as shown g 1n VFlgf whenmoving at the rearof a trav-f occupy less room cling car and so drawn in to in the street. Y Y Y Y The` practical operationpof my Vimproved rotary fender, above described, is probably Yipplvrent from thcdescription already given,

l Y the V:fendershould be forced into Yzo but may bebrieiiyrestated as follows :V With tbe fender advanced Vas in Figs. l and 2, aforrolling, the gear K upon truck l being engaged yWith'the smallerV gear L, upon. roll .L

causes the roll to revolve in an opposite dig rectionV and withY increased speed. WhenV thus in motion-if fthe Vrevolving guard-roll of the body of a person on the track, the effect ofi such revolving Vroll Vwould be to keepV the Y body from'being jammed under the fender 3,0k `for the'purposes specied: a'frevolving guard?VK the front of said frame audl and ycrushed by the car Wheels, and with the further Vpro'balole result of raising;V thebody and casting it on to the net and cuing it from fatal injury. f
