16 Claims. (Cl. 39--?) This invention relates to crossing gates for toy railroads and is more particularly directed towards toy railroad crossing gates having electromagnetic operating mechanism and lighted signal both of which are energized when the crossing gate is down and de-energized when it is raised.

The present invention contemplates toy railroad crossing gates having a base in which is housed an electrical unit including electro-magnet and lamp in parallel. The base supports a crossing gate arm, gravity biased to an up position and actuated by the electro-magnet to a lowered position. According to the present invention the electro-magnet and lamp and associated parts are in the form of a pre-assembled unit adapted to be secured in the base, and the lamp and lamp socket are removable for re-lamping.

According to the present invention the swinging arm of the crossing gate is provided with a transparent light transmitting member which receives light from the lighted lamp when the arm is down and re-directs this light to signals adapted to glow when the lamp is lighted.

Other and further objects will appear as the description proceeds.

The accompanying drawings show, for purposes of illustrating the present invention, one embodiment in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In the accompanying drawings:

Figure 1 is a perspective view illustrating the crossing gate with the arm in a lowered position;

Figure 2 is an enlarged elevational View, with parts in section, showing in full lines the crossing gate in a raised position, and in dotted lines the crossing gate lowered;

Figure 3 is an elevational view of the underface of the cross gate arm with parts in section;

Figure 4 is a view from underneath showing the light transmitting member detached;

Figures 5 and 6 are enlarged sectional views on lines 5-5 and 66 respectively of Figures 2 and 3;

Figure 7 is enlarged longitudinal sectional view through the base and arm, the arm being lowered;

Figure 8 is a vertical sectional view on the broken line 8-8 of Figure 7; Figure 9 is a perspective view illustrating the operating unit with the lamp and lamp socket; and

Figure 10 is a fragmentary view of a detail.

In the drawings the base of the cross gate is indicated generally at H], and the swinging arm at H. These parts are made of molded plastic material. The base is recessed from underneath as indicated in the drawings, and the arm is carried on a squared shaft I2, the shaft passing through bearing tubes l3l3 mounted in openings l4 near the top of the side walls of the base. Between the tubes It the shaft [2 carries an arm which shifts back and forth from full line position to dotted line position as indicated in Figure 7.

The operating unit for the crossing gate includes a magnetizable mounting plate It on which all parts are carried. A conducting plate H is insulated from the metal plate It by a sheet of insulation indicated at it. A solenoid coil i9 is mounted on a coil form and this coil form is held in position by a magnetizable yoke 2! having securing prongs 2!. One end of the coil is connected by wire 22 to the soldering lug 23 struck up from the conducting plate 11. The coil form 20 has projections 20a, 20b, which align it with the yoke and plate. The other end of the coil is grounded to the yoke. An arma ture 24 is carried in the coil form 20 and this armature carries a non-magnetic tip 25 which extends above the yoke and is provided with, a head 26 adapted to engage the undersurface of the arm I5. A dust cap 21 is placed below the armature.

The plate i6 is provided with a squared opening 28 with side notches indicated at 29-29 tov receive a lamp socket carrier to be desc -ibed, and the conducting element i! is provided with an upward bent resilient contact 36 to engage a socket contact. A bayonet type lamp socket 3|, carrying lamp 32, is secured to an inverted U- shaped clip 33. This clip is resilient and has feet 34-34 and finger grips 35 with outwardly extending detents 3B. The center contact of the lamp socket 31 is connected to a washer 38 insulated from the clips 33.

When the parts are in Figure 7 the feet 34 of the socket carrier are held against the upper surface of the metal plate [8. The grips above the detents 35 are in the notches 29 and the detents engage the underside of the plate It. The socket and socket carrier are thus held against movement. The spring contact is in engagement with the washer 38 as indicated in Figure 10.

The plate [6, together with the electromagnet, the lamp and the lamp socket are secured in place in the base by screws indicated at 39 and 49. The screw 39 passes through a wiring clip 4|, while the position shown in 3 the screw Ml passes through a wiring clip 42 and insulating sheet 43 and is threaded through a hole 44 in the plate l'l.

When the parts are assembled as indicated in Figures '7 and 8 the arm can be lowered by energizing the electromagnet and the same time the lamp 32 is lighted. Should it :be necessary to replace the lamp the finger grips 35 may be pinched together enough to disengage the feet 34 from the upper surface of the plate l6 and the lamp, lamp socket and socket carrier bodily removed through the opening 28.

The crossing gate arm H, is provided with counterweights 5t and is normally held in the position shown in Figure 2. The shape of the crossing gate arm is such as to resemble the usual crossing gate employed along the railroad right of way. As here shown the arm is provided with one or more openings 5i having downwardly facing shoulders ESL-Figures 5 and 'l. A transparent light transmitting member, preferably made of methyl methacrylate, is indicated at 53. It has an outer beveled end :54 adapted to fit behind ledges indicated 55-55 in the arm H, Figure 3. Near the outer end the member 53 is received between two resilient fingers 56, having hooks 51 to hold the transmitting member in place. Each of the holes El receives a signal element 58 in the form of a red transparent moulding. These mouldings bear against the upper surface of the light transmitting member 53 and are held in place by it. The inner, or left end, of the light transmitting member 53 is deeper, as indicated at 66, and is provided with a Sloping reflecting surface El below the inner one of the signal members 58.

The insulating base supporting the crossing gate is provided with an opening 52 opposite the filament G3 of the lamp 32 and so arranged that when the arm is in lowered position light rays from the lamp pass through the hole or window 62 and enter the end face 6t of the light transmitting member 53. if'his light is piped through the transmitting member and is reflected through its upper surface by one or the other of the reflecting surfaces Si or 54 so that when the arm is in a lowered position the colored signal elements 58 glow.

Since it is obvious that the invention may be embodied in other forms and constructions within the scope of the claims, I wish it to be understood that the particular form shown is but one of these forms, and various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
