Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed 'webruary 9, 1918. Serial No. 216,388.

To all whom it may concern:

Be it known that I, EDWARD P. HAINES, a citizen of the United States, residing in the cit of Philadelphia, county of Philadelphia, gtate of Pennsylvania, have invented a new and useful Apparatus for Distributing Cars,.of which the following is a specification.

My invention relates to apparatus for use in connection with the-trackage system of a freight yard of such desi n that a succession of cars or groups 0 cars, in being moved by means of a pusher or accelerator over a length of track which preferably includes a hump, will have imparted to them certain definite speeds, whereby they are caused to travel to the ends or other desired portions of the various branch tracks onto which they are switched, and one object of the present invention is to provide a syst m whereby a definite and predetermined speed may be imparted by a suitable motive power device to a car or a number of cars, which speed shall be dependent upon and variable with one or any desired number of such variable factors as the load on or weight of a car, atmospheric conditions as temperature, the direction and velocity of the wind, and the distance which it is desired the car shall travel after being released from such motive power device.

Another objectof the invention is to provide a novel combination of parts whereby the motive power is automatically cut off from the car or group of cars wheirthe 'latter has attained the predetermined speed 9 necessary to carry it to the desired point.

A further object of the invention is to provide novel means for automatically adjusting the device whereby the motive power is cut off from the car being moved, so that the speed imparted to th latter is caused to vary with the velocity and direction of the wind as well as with the temperature and load, either with or without hand controlled means for determining the speed of each car in accordance with the distance it is to travel as Well as with the car load.

I also desire to provide a system of the above noted typ which shall include means for manually controlling or predetermining the speed imparted by an accelerator to a car eitherin accordance with the load of the latter or with the distance said car is intended to travel,-or both.

' Another object of the invention is to procally, the motive power device or accelerator forming part of my invention, together with certain of the apparatus associated therewith; v

Fig. 3 is a diagrammatic elevation illustrating the apparatus for controlling theoperation of the accelerator; and

Figs. 4, 5 and 6 are diagrams illustrating the electrical connections and apparatus as-' sociated with three of the controlling members forming part of my invention.

In Figs. 1 and 2 of the above drawings, 1 represents a railroad track leading to a freight distributing or make-up yard, whose detail arrangement of tracks, forming no part of the present invention has not been illustrated. The particular part of the maintrack 1 with which the present invention has to do may be several hundred feet in length and preferably includes a so-called hump or raised portion to which the cars are delivered by a locomotive and on or beyond which said cars are accelerated so that each of them will reach its destination on definite ones of the branch tracks and yet without having such a speed upon its arrival as might cause it-to damage any other car at the same point.

To accomplish this end, I provide a pit 2 extending for a suitable distance between or adjacent the track 1 and in this pit provide an auxiliarvtrack 3 for the support of an accelerator diagrammatically illustrated This latter device consists of a frame mounted on wheels 5 and having hingedto it anarm 6 which under conditions of operation will occupy the vertical position shown in Fig. 1, so asto be capable of engaging the bumper or other suitable part of a car, there being a chain or cable 7connecting the upper part of said arm to the for- 'i'eit ill position, ni owing forward inl'o u The loo,

The position of the lower end of the link all) in the slot 430 is determined 1) the posivane 35, since the s cove 33 to is lined carries an eccentric 54.611- ;io i cd by on eccentric strap 55 on a rod 56, and lzl .nltcr, through a lever 57 and a link on, is coi'iuee'ted to the link 49 in such manner {lint Gil-1011 the wind is blowing in such a direction as to directly oppose movement of the core a; they travel from the pusher to their muons destinntions 1n the switch yard the lower end. of said link occupies the pooilion in the slot 50 illustrated in Fig. 3. (in the other hand, when the wind is blow inc; 'lroin such direction as to give a 1naxinun-n ussismuce to the inovelnentjof the cars, the vane 3 so shifted us to move the lower e ul of the link 4:9 toils extreme righthand position in die slot 50 and obvimisly with. ilie wind blowing frinn. any quarter inter nwdizilc i'lios noted, the link 4:9 is automatiill :ii'lju position on one side or the other of n e licnl line through the pivot 52.

The second arm of this latter lever is connected through a link 67 t a lever arm 68 which at its free endcarries the movable contact of the switch 29.

in the slot 50 to :1 correspond i turned through a I controlling windings of sition of said in the arc of a circle so Said lever 68 is also'conncctcd to the movable collar 69 of a centrifugal governor 70 whose balls are turned through a spindle 71, a pair of beveled gear wheels 72 and 73, and a shaft 74-75 driven by the motor 18. The two sections of this shaft are connected through a ratchet or tooth clutch 76, so that when the motor is driving the pusher to accelerate a car, the governor 70 is likewise operated, but is allowed to remain inactive when said motor is reversed so as to bring the pusher back to its starting position.

In addition to the link arm 49 and the weights 59, the scale beam 53 is acted upon by two wei hts 77 and 78, whose pos tions are shifted y a pair ofmotors 81 and 82 upon auxiliary beams 79,and 80 carried by said main scale beam. For this purpose the armature shaft of the motor 81 is connected through beveled ears and a vertical shaft 83 with a suitabTy supported endless belt connected to the weight 77 so as to be capable of moving it upon its supporting bar 79. Similarly the motor 82 is connected through gearing with a-shaft 84 andto a second endless belt, whereby the position of the weight 78 may be shifted upon its supporting arm 80. The point of engagement of the pin carried by the swinging arm 64 with the lever 66, is likewise determined by a motor 85, which through suitable gear-mg is arranged to actuate an endless belt 86 connected to the lower end of the swinging arm 64.

Of these three motors, 81, 82 and 85, the operation of. the first, and consequently the position of the weight 77 upon the scale arm, is made tobe dependent upon the temperature of the-atmosphere, and for the purpose of causing the automatic adjustment of said weight, I provide a thermometer such as the composite or thermostatic bar 90 (Fig. 6), connected to the movable contact 91 of a inulti-point switch 92 so that thepoarm 91 is automatically made 'tochange with variations of temperature.

Said arm has a series of pairs of coacting contacts 93-94, 95-96, 97-98, 99-100 and101-102, arranged in the arc of a circle, audit is noted that the contactsv 93, 95, 97, 99 and 101 are connected through suitable conductors to brushes 103-107, all mounted as to be capable of engaging a contact ring 108. This latter is mounted in a suitable manner so as to be redetermined angle for each revolution of the armature of the motor 81 to which it is connected by shafts 109 and 110, suitably geared together. This ring 108 is also connected to one terminal of a source of current-through a conductor 111.

' The contacts 94, 96, 98, 100 and 102 of the switch 92 are respectivelg connected to the ouble ole electromagnetic switches 112-116, w ose second of push buttons 129-133.

spectivel connected to the positive and negative con uctors 122 and 123.

With the arran ement shown in Fig. 6, if for example, a c ange of temperature occurs such as would cause the thermostatic bar to shift the switch arm 91 from the position shown, into engagement with the two-contacts and 96, then current would be free to flow through conductors 111, ring 108, brush 104, contacts 95,91 and 96, windingof switch 113 and through conductor 117 to the negative supply main. 'As a result,

the switch 113 closes and current is free to flow, from the supply main 122 through .rin section'118, one pair of contacts ofswitc 113, armature of motor 81, the. second pairiv of contacts of switch 113, ring section 120 and thence to the negative supplymain 123, As a consequence, the motor 81"..is put in operation and. shifts the weight 77 on its scale beam toward the pivot 52 until the ring 108 reaches a' position inwhich the brush 104 occupies the space between its two plpen ends whereupon current is cut off. from e-winding and switch 113. This latter immedlately opens, cutting off current'from the motor 81 and stopping, it, at which time the two brushes leading from the contacts of .said' switch have disc a d the rm sections 118 and 120. ng 2'- I Obviously a movement of the thermostatic bar 90 in the opposite direction, such as would be caused by a fall in temperature, results in the closure of one of the, switches 1'14 to 116 inclusive, and by reason of the semi-circular formation of the'ring sections 118-119 and 120-121, as well as'of their coacting'fbrushes, the motor in a reverse direction until it is by reason of the rings 108, etc.

again stopped into positions to disengage their ing moved brushes 81 is operated A practically similar system of rings, niain 3' switches and connections is provided for the manual control of the motor 82 and hence of the position on the scale beam of the weight 78 except that the energization of the windings of the main switches 124-128, is controlled by hand switches usually in the form each includes a fixed and movable con-tact of which the latter is mounted on or actuated by a movable bar to which is connected the armature 134 of an electro-magnet whose 4 bald S'WltOllGS' is UOl'lllQGll'll llivo new y main ant i Winding oi the oorr (in the Qaso illustraileil, tl- As a oonsazqnenco of this no: Mi

If for example, tho J 'th is closed, the main. switch 157 automatimilly closes, causing operation of iho motor and a consequent movement of tho nllaiu 86 which cm'itimles until the bar 6-4- has been swung to its oxh'me left hand, position on the lever 66L Thereupon :E'P, whim-h corrospomls (lirnctl u said motor is automatically stopped by reason of the open circuiting of the windings of the two switches 153 and 157 by their ring contacts 144, 146 and 148.

Upon ascertaining that the particular car to be accelerated is loaded to a quarter of its capacity, the operator likewise closes the switch 132, thus causing closure of the main switch 127 and operation of the motor 82 until the weight 78 takes up a corresponding position on the scale beam 80, whereupon the windings of said two switches 132 and 127 are open circuited by the ring contacts 136, 138 and 140. When the car to be placed has been brought by a locomotive, for example, to a position to the right of the accelerator 4, the operator starts themotor 18 by suitable manipulation of the switch 30 so that its arm 6 engagesthe rear bumper of the car. Thereafter he increases its speed until such time that the balls of the centrifugal governor raise the contact carrying end of the arm 68 sufliciently to close the switch 29, whereupon the switch 25 is opened and cuts oil the current from the motor 18.

Obviously this operation of the lever 68 is opposed by a force dependent upon the downward pressure on the link 64 as determined by the direction and force of the wind, 'the temperature of the atmosphere and the load on the car as well as by the distance which it is desired said car shall travel. By having these forces properly proportioned and applied, the car willleave the accelerator at a speed sufficient to carry it to the desired point and yet insutlicient to cause it to damage any other car upon reaching such point.

After the pusher has disengaged the car. the direction of operation of the motor 19 is" reversed by suitable means and said pusher-is returned to its starting point the arm 6 swinging to a horizontal position so as to permit a second car to pass over it ready to be acted upon as above described. As above indicated, the accelerator may be returned to its starting position at any desired speed since when the motor 18 is reversed, the clutch 7 6 operates to disconnect it from the governor 70. Obviously when said accelerator or pusher is again moved by the motor 18 toward the car, its arm 6 is automatically raised into position to properly engage the same.

It will be noted that the wind mill is so coniiected to the scale arm 53 that when the wind opposes movement of the car, it acts to cause the accelerator to be operated at a higher speed, this being due to the fact that the lever-49is exerting a downward force on the end of the scale beam 53. When however, the wind is blowing from a direction to assist car movement, the downward-pressure exerted by the lever 49, acting on the right hand end of the scale beam, tends to cause the motor 18 to be cut out of circuit before the speed of the accelerator has reached such a high point.

While I preferably employ all of the devices above described so as to impart to the car a speed which shall vary with the temperature, direction and velocity of the wind, car load and distance to be traveled, I may. omit one or more of them and cause said speed to be dependent upon the remainder without departing from my invention.
