CABLE-CROSSING.

SPECIFICATION forming part of Letters Patent No. 510,151, dated December 5, 1893.

Application filed December 24, 1892. Serial No. 456.285. (N0 model.)

To all whom it may concern: I

Be it known that I, WILLIAM W. BAILEY, a citizen of the United States, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Cable Railways, of which the following is a specification.

Myinvention has for its principal object to provide an effective, practical and mechanical means for conveying cable-railway cars across other cable-railways running in the same or nearly the same plane as, and at an angle to, the first and consists of mechanism hereinafter described whereby the cars are propelled across the crossing by power derived from the main cable or other motor and it also provides means to enable the grip man when the grip connected to thecar is released from the main cable to stop the caron any part of the crossing and to start the same again by power.

Another object of my invention is to provide effective mechanism for conveying the cars around curves without having the grip connected to the main cable, and also, for switching cars from one track to another by power, all of which I attain in the manner hereinafter set forth, reference beinghad to the accompanying drawings,in which- Figure I is a vertical longitudinal section of a cable railway showing the driving mechanism at the intersection of the cross tracks, illustrating the manner in which the cars are propelled across the crossing. Fig. II is a plan showing the cross tracks on the surface. Fig. III is a sectional plan with the track cut away, showing the driving mechanism. Fig.

IV is an end view of the main and auxiliary. Fig. V'

sheaves for driving the center rolls. is a side view of the rolls, showing the way in which the shoe connected to the grip engages with the rolls. Fig. V1 is an end view of the main and auxiliary sheaves. Fig. VII is a side view of the same. Fig. VIII'is a sectional view of driving rolls showing form of tread.

1, 1 represents the main cable deflected to one side and running under the

cables

2, 2 which are to be crossed.

3, 3 are the two main driving sheaves for the auxiliary cables and here shown as driven bythe main cable which passes around them. 4, 4, 4* 4 are the sheaves on the shaft 4 of one of the main driving sheaves 3 for the purpose of driving the trains of

sheaves

5, 5 which are keyed fast to the transverse shafts 8.

6, 6 are idlers or loose sheaves alternating 8, 8 are transverse shafts upon which the sheaves 5 and rolls 7 are keyed fast and the idlers 6 run loosely. All of the shafts 8 are set in boxes placed upon suitable iron frames which rest on the foundations in the conduits.

9, 9 are the conduits through which the respective cables to be crossed are laid as shown in Fig. I.

10, 10 are auxiliary cables passing over the sheaves 4, 4 and 5 for the purpose of driving the rolls7 on shafts 8. (See Fig. III, IVandVI.)

11, 11 are pulleys which hold down and tighten the four

auxiliary cables

10, 10.

12, 12, 12, 12 are sheaves for the purpose of guiding and deflecting the main cable out of its direct line and to bring it in line to pass over the

main driving sheaves

3, 3 which drive the train of rolls and also to release the main cable from the grip. When opened the friction shoe comes in contact with the tread of the rolls 7 for the purpose of propelling the car over the cross cables which are shown between and below the tread of the rolls 7.

13, Fig. V, shows the grip open and released from the main cable and having a shoe 14, connected to its movable part, so constructed that it can contact with two of the rolls simultaneously. See Figs. IV and V. I have shown the shoe in this case connected to the rest in to prevent them from chafing on th

main cables

1, 1.

16 (Fig. VIII) is a V groove in the tread of the rolls 7 for the purpose of guiding the shoe 14 in a direct line of the slot on the surface and also to produce additional friction to propel the cars over the cross cables. The shoe has a V-shaped fin 14", see Figs. IV and Vto engage in this groove.

17, 17 (Fig. II) are the up and down tracks of a double track railway. 18 are the cross tracks. 19, 19 are the slots on the said up and down tracks for the grip to run through and 20 the slots for the grip on the cross tracks.

The

main cable

1, 1 being deflected down and to one side of the center lines, passes around the main driving sheaves 3, 3 (Figs. I and III) which in this case drive the train of

rolls

7, 7 by means of the

cables

10, 10 passing over the sheaves 4, 5, and under idlers 6 on one side and directly opposite on the other 'as will be seen in sectional plan, Fig. III which enables me to drive all the trains of rolls in one direction over the crossing.

The sheaves I, 4, I, 4: are keyed fast to the shaft that carries the main driving sheave 3 and the

sheaves

5, 5 are keyed fast to the shafts 8 as are also the rolls 7 while on each shaft 8 is an idler or loose sheave 6 on the opposite side of its fast sheave 5 and as will be seen by an inspection of the drawings the fast and loose pulleys alternate with one another on each side. By this construction I am enabled to place the driving rolls 7, 7 close to each other only having sufficient space to permit the cables to pass over one and under the other. By placing the rolls close together it also enables me to have ashoe on the grip engaging with two rolls at the same time and not much longer than the grips which are now in use on cable railways. Having laid the drawings down to scale, I find that three three-foot sheaves and rolls can be placed between the slots of the two tracks of a double track crossing.

The

rolls

7, 7 can be made with chilled treads, or with steel tires, having double flanges to prevent the shoe from crowding to one side which would wear the plates of the grip by coming in contact with the sides of the slot rails. The V in the tread acts as a guide and increases the friction as the shoe has a projection to fit in same, and both come in direct contact with the tread of the rolls.

The frames and journal boxes for the

main driving sheaves

3, 3, sheaves 5, idlers 6 and driving rolls 7 on shafts 8 are not shown on the drawings as they can be made of any suitable form well known to mechanics. Neither are the walls and chambers around the driving machinery shown in the sectional plan, Fig. III, as they can be made to conform to the conditions of the road bed.

The tighteners 11, 11 are intended to be adjustable in a manner common to belt'tightening rolls for the purpose of taking up the slack of the

auxiliary cables

10, 10 which drive the train of rolls. The

main cable

1, 1 being gripped, the car approaches a cable road running at an angle with it, the cross cables passing over the one which is gripped. WVhen the car arrives at the point where the main cable is deflected, and directlyover the rolls 7, the grip-man releases the cable which having more or less strain upon it from being deflected from a direct line, passes out of the grip and strikes one of the outer rolls 12. The grip being opened wider, the movable jaw is thrust down and the shoe 14, which in this case is connected to the grip, comes in direct contact with the tread of the

rolls

7, 7 with sufiicient friction to propel the car over the

cross cables

2, 2. If there should be an obstruction upon the track before the car arrived at the crossing, or, if a car be passing over the crossing, the grip-man raises the shoe by the same lever that is connected to the movable part of the grip, releasing the shoe from contact with the

rolls

7, 7 and by applying the brakes, stops the car and so prevents serious accidents on the crossings. hen the obstruction is removed, the gripman lowers the shoe again until it comes in contact with the

rolls

7, 7. Then the car starts and is propelled over the cross cables.

I do not confine myself to driving the train of

rolls

7, 7 by auxiliary cables as they may be driven by friction rolls, or gearing placed between them in place of the sheaves. The tread of the rolls may be made flat without the double flanges.

The driving rolls may be placed on a curve and be driven by the main cable or otherwise,

and be arranged in such a manner that the shoe can be brought in direct contact with them with sufficient friction to propel the car around the curve and at the same time relieve the main cable from the very great strain to which it is subjected when it travels on guide rolls placed in the conduit around the curve.

The train of rolls can be placed under turnouts Where cars are switched from one track to another, the shoe coming in contact with the rolls the same as they do on the crossings.

The train of rolls may be driven by some other power than from the main cable; therefore, I do not limit myself to driving them from the main cable.

It will be noticed that the grip-man, by depressing the shoe with sufficient force can throw any necessary part of the entire weight of the car onto the shoe for the maintaining of a frictional contact with the friction devices hereinbefore referred to as the driving rolls; and that connection of the shoe to the driving rolls is nevertheless so free that to re lease their action, the grip-man has but to raise the shoe from contact; and that, the action being against the top of the frictional devices, any wear of any of the parts does not in the least affect the perfect operation of the mechanism being fully compensated for by a slightly greater depression of the shoe with merely a slight increase of the throw of the grip-mans lever.
