AUTOMATIC WHEEL-GUARD.

Patented Au. 2.0, 1912.

Application filed May 12, 1910, Serial No, 560,926. IRenewed iEebruary 2, 1912. Serial No. 675,095.

T 0 all whom it may concern:

Be it known that I, CHAnLns E. Gimm- ING, a citizen of the Uni-ted States of America, and a resident of Bellevil'le, in the State of New Jersey, have invented a new and useful Improvement in Automatic lVheel-Guards, of which the following is a specification.

This invention relates to those street-car fenders known as automatic wheel guards of the trip and drop-scoop type, and particularly to those in which the cradle or scoop is attached to the truck, where there is the minimum of oscillation, adapting the scoop to be carried as close to the track as the condition of the pavement will permit.

It relates especially to the adaptation of such wheelguards to cars having swi-veled trucks, and to those cars in which :it is impracticable to employ centrally located connections between the tripping gate and the drop scoop, owing to the obstruction of the space beneath the car platform by swinging draw bars and the like.

The present invention consists in certain novel combinations of parts, and in an improved automatic wheel guard embodying such combinations or any of them, all as hereinafter particularly described and claimed.

In previous specifications, forming part of United States Letters Patent No. 935,491 dated September 28, 1909, and an application for Patent filed February 6, 1909, Serial No. 476375, I have set forth automatic wheelguards for swivel-truck street cars, having, as elements of each wheelguard, a curved bar hinged to arms carried by the scoop, and a central longitudinal locking bar, connected with said curved bar, normally locked against endwise movement and tripped by the gate to drop the scoop.

The leading ob ects of the present invention are to render it practicable to dispense with such central longitudinal locking bar, and, at the same time, to provide for n0rmally supporting thescoop in its raised position and for instantaneously dropping the scoop when the gate is swung on its hinges; the supporting and tripping means being adapted for accommodation beneath the sills .of cars on which it would be impracticable to employ such central longitudinal connections.

Other objects will be set forth in the general description which follows.

' Two sheets of drawings accompany this specification as part thereof.

Figure 1 is a top view of one species of the improved wheel-guard, and of adjoining portions of the sills and of one truck of a swiveled-truck street car, illustrating its attachment thereto; Fig. 2 is a side elevation projected from Fig. 1, showing the scoop up; Fig. 3 is a side elevation of the same parts, showing the scoop dropped; Fig. 4 is a partial side view on a larger scale, showing the movable parts in full lines, as in Fig. 2, and in dotted lines as in Fig. 3; Fig. 5 is a partial side view on the same scale as Fig. 4 showing a second species of the improved wheel-guard; Fig. 6 is a fragmentary view further illustrating said second species (Fig. 5); and Fig. 7 is fragmentary top view mainly projected from Fig. -6.

Like reference characters refer to like parts in all the figures.

The principal parts of the improved wheel-guard are a tripping gate, a, hinged at its upper edge or top to the outermost car sills, 1 and 2, beneath the platform, 3, of the car body, by a pair of hinge-brackets, l and 2', interacting with a horizontal rock shaft, 3; a cradle or drop scoop, Z) or 6 hinged at its rear edge or back by a pair of hinge brackets, 4L and 5, to the frame, 6, of the adjoining car truck, the truck being of a swinging or swiveled type, and said scoop being provided with a pair of upwardlyprojecting lever arms, 7 and 8, near the respective sides of the truck; a curved bar, 0 or 0 I of round bar lron, known to some as a radial bar, attached to or connected with the upper ends of said lever arms 7 and 8, the-curve of said bar being an arc of a circle the center of which is the axis around which the truck turns on curves; and a horizonta'lly swinging bar, (Z or (Z known also as a rocking lever, transverse with reference to the longitudinal axis of the car, which bar is loosely pivoted to a depenc'ling bracket, 9, bolted to said sill 2 at one side of the car, and carries or includes a bracket or yoke,

10, within which a pair of grooved wheels, 11 and 12, turn on vertical pins, to interact with said curved bar at midlength, as a frictionless push-and-pull connection, or anti-friction means effecting a sliding connection between said swinging bar and said curved bar.

The gate a is or may be of the construction set forth in said previous specification forming part of Letters Patent No. 935491, except that instead of a central tappet on the rock-shaft 3, the latter is provided at a convenient point with a short lever arm, 13, which projects upward at a suitable angle. From said lever-arm 13, a connecting. rod, 14, having a lost-motion device in the form of an open loop,15,extends to alever-arm, 16,

on a rock-shaft, 17, arranged parallel with said rock-shaft 3 of the gate a, and mounted in hangers, 18, bolted to said side sill 2 and to two middle sills, 19 and 20. See Fig. 1. Between said middle sills 19 and 20, said rockshaft 17 carries, at approximately right angles to said lever-arm 16, a lever-arm, 21, which interacts with one end of a togglestrut, 22, the other end of which is connected by a loose pin-joint, 23, Fig. 1, to said swinging bar d or (Z Normally the toggle formed by said strut 22 and arm 21 is selflocked, as shown in Fig. 2, in full lines in Fig. 4, and in Fig. 5; the upwardly bent front end, 24, of the strut, interacting with the rockshaft 17 as a stop or locking device; and, by the interaction of said strut 2122, the swinging bar d or (P, the curved bar 0 or 0 and the arm 7 and 8 of the scoop Z) or 5 the scoop is held in its normal or raised position as shown in Fig. 2, in full lines in said Fig. 4 and in Fig. 5.

When the gate a swings inward from the normal position in which the gate is shown both in Fig. 2 and Fig. 3, the rockshaft 3 with its lever-armv 13, the connecting rod 1415, lever arm 16, and rockshaft 17, transmit motion to the toggle arm 21 and strut 22, breaking the toggle upward by upwardly moving the pivot which connects the toggle members 21 and 22, until this pivot passes its locking position or plane, and permitting the scoop Z) or b to drop, as represented in Fig. 3 and by dotted lines in Fig. 4. This final movement is effected by the gravity of the scoop supplemented by the tension of the spring 6. To provide for varylng the height of the front edge of the scoop in its said normal or raised position, at will, to meet the requirements of different pavements, the toggle strut 22 is conveniently made in two parts united by a lap joint, with tap bolts, 25, Figs. 1 and 3, each of which passes through a longitudinal slot, 26, in one of the part-s, into a tapped hole in the other part of the strut.

To overcome the inertia of the tripped sco Z or b and to hold the free edge of the scoop down in its dropped posit-ion (Fig. 3 and dotted lines in Fig. 4), a tensile spring, 6, (Figs. 15) preferably of coiled rod steel, is stretched from the swinging bar 6! or 5Z to the rockshaft 17.

For raising the dropped scoop b or b from the car platform, to reset the wheelguard, suitable means operable by a man on the platform, preferably in the form of a foot plunger, 1, Figs. 1, 2 and 3, at one side of the platform 3, is connected beneath the platform to one arm of a bell-crank lever, 27, which is conveniently pivoted to a bracket, 28, bolted to said side sill 2, and connected by a connecting rod, 29, having a lost motion device, 30, preferably in the form of an open loop, to a lever-arm, 31, on the rockshaft 17. This lever-arm 31 projects downward when the scoop is dropped, as shown in Fig. 3 and in dotted lines in Fig. 4, and, when pulled by the depression of the treadle f, transmits resetting motion through said rockshaft 17, the toggle arm 21 and strut 22, and the swinging bar (Z or (Z and curved bar 0 or 0 to the lever arms 7 and 8 of the scoop b or 5 turning the scoop on its hinges at4 and 5, and stretching the spring 6 until the toggle 21-22 is straightened, and its locking end 24 again interacts with the rockshaft 17, as in full lines in Fig. 4.

1n the species represented by Figs. 1 to 4,. inclusive, the curved bar 0 is connected with said lever- arms 7 and 8 of the scoop b, as in said previous specifications, by hinges, 7 and 8, having a horizontal axis; such hinges being preferably formed by providing the curved bar 0 with straight ends, and providing said lever- arms 7 and 8 with hook-shaped upper ends adapted to embrace said straight ends of the curved bar, and with bolts (32, Fig. 4) by which the accidental separation of the parts is prevented. The swinging bar (Z, correspondingly, is ex tended beneath both of the middle sills 1920; and its free end works in a bracket,

34, Figs. 12 and 4, bolted to said sill 19, to

sustain the weight of said free end of the swinging bar (Z and its load, including that of the curved bar 0, and to maintain the bar 0 in a horizontal plane as in Fig. 4.

In the species represented by Figs. 5 to 7, inclusive, said hinges 7 and 8 are omitted, and the curved bar 0 is rigidly bolted to the upper ends of the lever arms 7 and 8 of the scoop Z2 being constructed with downturned and flattened ends (35, Fig. 5) for this purpose; and said bracket 34 (Fig. 4) is omitted so as to permit the free end of the swinging bar d to accommodate itself to the angular movement of the rigid curved bar as shown by full and dotted lines in Fig. 6.

In both species, the scoop b or b is adapted to be hinged directly to the frame 6 of the car truck by said hinge brackets 4 and 5;

the customary pilot board 36 being bolted to said lever arms 7 and 8, so as to utilize to the utmost the length between the truck frame and the extremity of the car platform, or the space beneath the sills otherwise available, for the accommodation of the wheel-guard devices. Otherwise the scoop 7) or Z), in both species, is preferably and conveniently of the construction set forth in said previous specifications, except that it is preferably provided with runners, 37, distinct from the brace extensions or feet, 38, of the lever arms 7 and 8, and which are relatively light and resilient.

The dotted lines at 4, 5 and 6, Fig. 1, illustrate the attachment of the hinge brackets 4 and 5 to the end of a square-ended truck. The hinge brackets (45 or 4-5) are in all cases bolted to the truck as wide apart as may be convenient, so as to render the scoop as steady as practicable in its raised position.

For the purposes of the present invention both the gate a and the scoop b or b may be of any known or improved construction adapted to the mode of operation hereinbefore specified; and other like modifications will suggest themselves to those skilled in the art.
