NORMAN -W'I-IICHELLO AND HARRY SAWYER, OF MUSKEGON, MICHIGAN.

TRANSIT DEVICE.

Application filed. September 29, 1913.

Q0 all whom it may concern Be it known that we, NORMAN VVHICH- mane, a subject of the King of England, and HARRY Sawvnn, a citizen of the United States, and both v residing at Muskegon, county of Muskegon, State of Michigan, have made a certain new and useful Invention in Transit Devices, of which the following is a specification.

The invention relates to transit devices.

The object of the invention is to provide a swinging bridge member for a traveling or movable crane, to connect the track rail of the moving crane with an associated track rail, so that a trolley may run safely from the one to the other, notwithstanding that those two track rails may not stand in exactly correct relative locations longitudinally vertically or laterally.

A further object of the invention is to provide safety buffers, which operate to prevent the trolley from running off of an open end of the track rails before the bridge member is in position to connect or bridge the space between said rails, and to be automatically raised out of the way of the trolley when the bridge member attains its connecting or bridging relation between the two tracks. I

A further object of the invention is to provide means whereby the power which controls the lateral movement of one track is rendered inoperative when the bridge member is in connecting relation with the other track.

A further object is to provide means to automatically bring. the bridge member into proper relation with the track when it is lowered into bridging position.

- The invention consists substantially in the construction, combination, location and relathe arrangement of parts, all as will be more fully hereinafter set forth as shown in the accompanying drawings and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference signs appearing thereon, Figure 1 is a view in side elevation showing a construction embodying the principles of our invention, parts broken off, and the bridge member in bridging relation between track rails of a monorail track system. Fig. 2 is a diagrammatic view showing the bridge in open position and the spring buffers employed as safety stops for the trolley in their normal Specification of Letters Patent.

positions, and also illustrates the electric circuits controlling the motor which operates the moving tracks and the safety buffers respectively. Fig. 3 is a view similar to Fig. 2, showing the bridge member in lowered position and its effect on the circuit controlling themovement of the buffers and also on the motor which controls the lateral movement of the moving track. Fig. 4 is a plan view showing a slightly modified arrangement and also showing the position occupied by the bridge when in bridging position with the two tracks considerably out of line. Fig. 5 is a detail view in section on the line A, A, Fig. 1 showing the means for connecting the bridge member with one of the track sections. Fig. 6 is a similar view on the line B, B, Fig. 1. Fig. 7 is a view similar to Fig. 1 showing a slight modification, the bridge member being shown in open position. Fig. 8 1s a broken view in section on the line C, C, Fig. 7..

Fig. 9, is a view similar to Fig. 4: showing a plan of the arrangement of Fig. 1.

The same part is designated by the same reference sign wherever it occurs throughout the several views.

In the use of monorail trolleys, it is often required that the trolley be run from a fixed track to a moving track or the reverse or from one moving track to another moving track. The moving track may be carried by an overhead bridge like a traveling crane bridge operating on overhead tracks, or by a gantry crane operating on ground or floor tracks, or by other means. In bringing the track ends together, in order to enable the trolley to pass from one to the other, it is essential that they should be in accurate relative location, so that the trolley can pass across safely and without objectionable shock. If the opposing tracks fail to register properly, as, for instance, if one of the tracks is out of level with the other, due to settlement or deflection of one or the other of said tracks or supports, or if the tracks are offset by reason of one of the tracks being carried too far or not quite far enough before stopping, or if the clearance space between the proximate ends of the track sections varies, there is danger'of the trolley not passing safely from one track to the other.

The difference in level or vertical height is much more likely to occur with the moving track carried by a gantry frame than if carried by abridge running on rails carried by the same structure which carries the cooperating track, and this is also true of the end clearance, because there is more opportunity for deflection, settlement and imperfeet alinement of the crane runway. In a moving track carried by a gantry crane the possibility of variation in end clearance due to settlement of foundations, deflections and other causes may be considerable. It is necessary however that suflicient clearance between the proximate ends of the track sections should be provided so that under no circumstances could the end of one track strike the proximate end of the other track if the one is to pass by the other. When such a clearance is allowed and the clearance is increased by deflection or settlement in the structure it might result in too great a gapbetween the proximate ends of the track sections for the trolley to pass over safely and smoothly.

Our present invention is designed to overcome these and other difiiculties, and in carrying out the objects of our invention We allow a considerable clearance space between the proximate ends of the track sections. In the forms which we have selected tolillus trate our invention, we employ track rails in the form of flanged I beams, the trolley being designed to run along the lower flanges of the beams; Our invention however is not to be limited or restricted in this respect, as other forms of tracks are also contemplated. In the drawlngs, 1, desig- "nates one track section, and 8 the other track.

Both the tracks 1 and 8 are provided with end shoes 2 and 18, preferably of cast steel which form eonti'nuations of the track beams. Loosely pivoted to the end shoe 2 of one of the track sections is a bridge piece or member 4., which is capable of being rocked until its outer end, rests on the pro jecting end of shoe 13 of the other track section 8.

Arranged on each track end are safety stops or butters 9, which operate, when in normal. position, to prevent a trolley running oii the open end of either track, when not registered with the other track, through the bridge member. The buffers 9 are preferably constructed with heavy springs 10 to diminish the shock in case a trolley wheel should bump against either of them.

V\ hen the bridge member 4 is lowered into bridging and registering relation with track, 8,"the safety buffers, in accordance with our invention are automatically raised out of the way of the trolley truck wheels. In the particular form shown for accomplishing this we employ solenoids, indicated at 12. The buffers drop by gravity into their safety positions whenever the current flowing through the solenoids is shut off.

The bridge member 4 may be raised or lowered by any suitable means. e have shown a lever 5 for this purpose, see Figs. 2

and 3, which is connected by suitable links and levers 80, to the rocking bridge member 4. 7 If desired, and in order to insure that a movable track may not be shifted whilethe bridge is in lowered position we propose to open the circuit of the motor which moves said track whenever the bridge is lowered. A simple arrangement for accomplishing this is shown as one example of operative connections for the purposewherein the lever 5 is arranged to operate a switch 15 in the circuit of the motor 31 which moves the movable track. This switch is so arranged that when the lever 5 is rocked to lower the bridge member 4 the switch 15 is opened, thereby opening the circuit of mozor 51, and consequently the lateral movement of the moving track 1 is prevented. Of course other specific forms of means for accomplishing this purpose would readily occur 7 to skilled mechanics without departure from our invention.

It is apparent that if track 1, has been brought into correct location relative to track 8, bridge "member 4 can be lowered until its outer end engages correctly with the shoe on the proximate end of track 8. Should the location of track 1, deviate within certain limits, either vertically, laterally or longitudinally from correct location, the

bridge member can still be lowered into correct engagement with the end shoe of track 8, notwithstanding such devlation. Various arrangements for securing this correct engagement, in case of such deviation, may be employed. In one form shown in Figs. 1 and 5, the shoe 13, is provided with a cone shaped projection 14, which is received in an inverted, correspondingly shaped seat in the free end of the bridge member 4, when the latter is lowered into bridging relation, and the hinge of bridge member 4 is carried as at 17 by swinging links 18, 19, pivoted to the end shoe 2. In the arrangement shown in Figs. .4, 7 and S, the end casting or shoe 372 is providedwith a V-shaped projection 33, which is received in a correspondingly shaped seat in the bridge member 4. The hinge of the bridge member is also made sulliciently loose to permit of av desired range of flexibility of movement of the bridge member relative to track section 1. From this construction it will be seen that if the deviation of, the tracks 1, 8, from correct' track section 8, the looseness of the hinge of the bridge member permitting such movement of said member. Should the deviation of track position be longitudinal, that is, should there be a variation in the clearance space between the proximate ends of tracks 1 and 8, then it will be seen that with the construction shown in Figs. 1, 5, 6 and 9, the inclined face of the cone projection 14, engaging with the corresponding surface of the seat in the bridge member when the latter is lowered into bridging relation, will cause the bridge member to move endwise, thereby bringing its free end into correct endwise relation with respect to the shoe on the end of the track section 8. The looseness of the hinge of bridge member or the swinging of the links 18, 19, will permit this endwise movement of the bridge member. Any variance in the end clearance in this case, will appear as a variance in the length of gap between the ends of bridge member 4, and the shoe at the end of track section 1, see Fig. 9. With the V-shaped registering device shown in Figs. 4, 7 and.8, there will, of course, be no such endwise movement of the bridge member and consequently any variance of end clearance will appear as avariance in the length of the gap between. the free end of the bridge member and the shoe at the end of track section b, see Fig. 4. Should the deviation of track position be vertical, the bridge member, by reason of the looseness of its hinge, or its swinging hinge supports, will readily adjust itself to such deviation by assuming the necessary vertically inclined position.

In order to insure the withdrawal of the trolley wheel buffers 9 when the bridge member is in proper bridging relation but not unless and until said member reaches that relation, we provide means operated by the bridge member as it approaches its final seated position in bridging relation, to effect the withdravml of the butters. In the particular arrangement shown, to which, however. our invention is not to be limited or restricted, we provide a switch in the circuit of the solenoids 12 which-is operated to close said circuit when the bridge member is lowered into position. In one form of switch device for the purpose, the cone shaped projection 14 is provided with a pin '7, see Figs. 1, 5 and 7, which is engaged by the bridge member when it attains its final bridging position. and which operates to close the switch 34, in the circuit of the two solenoids 12 carried respectively by or respectively associated with tracks 8 and 1, which operate to raise the spring buffers 9 so that the trolley wheels may pass freely under them. \Vhen the bridge member 4 is not pressing on pin 7, switch 34 will be held normally open by suitable retracting means, such, for example, as spring 105;

In order that the circuit of the solenoids 12 may be completed only when the track sections 1 and 8 are brought into opposite or nearly opposite relation to each other, one of said track sections as 8, for instance, has associated therewith short conductor sections indicated at 101, 102, Figs. 2 and 3, respectively constituting terminals of the solenoid circuit. The other track section carries current collectors or contacts 103, 104, adapt ed to be brought into contacting relation with respect to the conductors 101, 102, respectively, when the two track sections 1, 8, are brought opposite or nearly opposite to each other. The solenoid circuit includes these contacts or collectors 103, 104. This arrangement permits the relative movement of the track sections past each other and the completion of the solenoid circuit, whenever the track sections are brought opposite or nearly opposite each other as follows from the positive side of a convenientsource of current to conductor 102, collector 104, to one solenoid coil 12, to collector 103, conductor 101, the other solenoid coil 12, through switch 34 to the negative side of the current source.

The pin 7 is so placed that the bridge must be practically in its fixed position before it sets upon the pin to close the switch and raise the buffers 9. This is an important feature of our invention as serious results might follow if the bridge member could close the electric switch 34 and raise the buffers 9 before the bridge had reached a position to form a smooth continuous track.

To prevent objectionable jolt in case of the extreme limit of end clearance between the proximate ends of either track and the bridge member, which would cause a gap in the track surfaces, one end of the bridge member and the opposing end of the track on the casting are off set or staggered longitudinally of the track sections on opposite sides thereof. An example is shown at 35, 36, in the plan view of the drawing. Fig. 4, also in Fig. 9. prevents two opposite wheels on a truck passing the gap in the track at the same time, and insures that diagonal wheels of the truck are supported at all times by solid track surfaces. Any one of the four wheels of a rigid four wheeled truck can pass over a gap without objectionable shock. I

The operation of our invention in the specific embodiment thereof selected for illustration is as follows: The track sections 1, S. are brought opposite to each other, or nearly so, thereby bringing contacts 103, 104, into contact with conductors 101, 102, then the operator pulls the lever 5 from the position shown in Fig. 2 to the position indicated in Fig, 3. This operation lowers the bridge member 4 which causes This arrangement (ill the switch 34 to close by the bridge member bearing on the pin 7. The closing of the switch 34 energizes the solenoids 12 which raise the buffers 9 and the trolley is able totraverse from the one track to the other. The operation of the lever also opens the switch 15 controlling the circuit of the motor 31 which moves one of the tracks as l for instance, thereby preventing any travel of said track relative to track 8 while the bridge is in lowered position. When the bridge is raised by reversing the above movement of the lever, the circuit controlling the solenoids is opened by the spring or other retracting means 105 acting on switch 84, and the buffers gravitate to their normal safety position, and the circuit is againclosed to the motor 31 for controlling the lateral movement of the moving track.

It will be seen that in our invention a simple and etficient transit device for trolleys from one track to another is provided and whereby a variable level or clearance space between the two tracks or a variation in lateral relative position thereof are taken care of so that a trolley may safely pass across without danger of jolting or dropping through too great a gap. Also so that a moving track can pass by a relatively fixed track without danger of colliding therewith laterally. It will also be understood that the lever 5 may be controlled from any suitable or convenient point, as for instance, the control cage of the traveling crane portion. It is to be understood that our invention is not to be restricted to the use of track sections which are traversed along straight tracks or in a straight line.
