T01. aZZfw/l'om itfmay concern Be it. known that we, Pn'rnn and ANGELO Bucn onani, citizens of the United States, residing at Swatara Station, in the county of Dauphin, and State of Pennsylvania, have invented new and useful. Improvementsin Stopping Apparatus for liIotor-C'ars, of which the following is a specification.

This invention relates to improvements instopping apparatus for motor cars and has particular application to signal controlled apparatus of this character. 7

In carrying" out the present inventiomit is our purpose to provide apparatus of the class, described whereby the propelling power of the motor car Will be cut off and the brakes applied in the event of the car or train passing a danger signal and whereby a signal will he sounded simultaneously with the cutting oil of the propelling power and the application of the brakes.-

It is also our purpose to provide stopping apparatus for motor cars which will embrace the desired features of simplicity; eflioiency and durability, which may be installed and maintained at a minimum expense and which will. operate effectively under all conditions.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings; Figure 1 is a fragmentary top plan view of a trackway showing the, relative positions of the track instrument and signal. Fig. 2 is a fragmentary longitudinal sectional view through the trackway showing the instrument in side elevation. tional view on the line 33 of Fig. 1. Fig. 4' is a diagrammatic view of the car carried mechanism. Fig. 5 is a view in side elevation of the circuit closer. Fig. 6 is a sectional view on the line 66 of Fig. 5. Fig. 7 is a similar .view on the line 7--7 of Fig. 5. Fig. 8 is an enlarged fragmentary plan view showing the connection between the motor and brake valve. Fig. 9 is a perspective view of a detail of the car carried mechanism.

Referring now to the drawings in detail, 1 designates a trackway which is preferably divided into blocks and located at the en,- trance to each. block and controlling trafie Fig. 3 is a cross sec- I thereinto is a semaphore 2 comprising a standardv 3 and a signal blade 4 pivoted upon the standardadjacent to the upper end thereof and capable of movement to danger and clear positions. lines of rails of the trackway at the entrance toeaoh block is a track instrument comprismg a substantially rectangular base plate 5;-

arranged longitudinally of the track and equlppfld" with. upwardly projecting pivot ears 6, 6- spaced apart and having the open- Paeemeenar. 1c, 1915.-

Di'sposed between the ings therein alining axially with each other and having the axes thereof lying parallel with the adjacent lines of rails. Journaled in the ears 6 are axially alining trunnions;

7 carriedby the opposite extremities of an obstacle plate 8 capable of swinging movement tovertical and horizontal and adapted, when in vertical position, to lie parallel with the lines of rails of the track. Depending from the lower edge of the obstacle plate 8 and workingwithin a.

transverse slot 9 formed, in the base plate 5 is an arm 10 having the lower end thereof connected through the medium of a rod 11 with one limb of a 'bellcrank lever 12 pivoted for swinging movement upon a suitable support and having the remaining limb thereof connected through the medium of suitable link mechanism 13 with the signal blade 4 of the adjacent semaphore 2. When the signal blade 4 is actuated to danger po- .sztion motion is transmitted to the arm 10- .through the link mechanism 13. bell crank lever 12 and rod 11 and the obstacle plate 8 swung'to vertical or active position. On the other hand, when the signal blade is actuated to clear position, the plate is swung to a horizontal plane or inactive position. In

this embodiment of our invention, we have shown the car carried stopping mechanism as installed in a steam driven locomotive and in this connection we wish it to be understood that this mechanism may be installed in locomotives driven by electricity, air, gas, liquid fuel and the like without de' parting from the spirit of our invention, In the present instance, the car carried stopping mechanism comprises an electric motor 14 connected in an electric having one end of the armature shaft thereof projecting outwardly-bf the adjacent extremity of the casing. Fast upon the projecting end of the armature shaft is a worm 16 meshing with a worm wheel 17 keyed upon a countershafi; 18 journaled in hori positions circuit 15 and" zontally alining; bearings 19 and lying; in a plane parallel vvith'the armature shaft of the motor. I

20 designates the steam main leading from the steam dome of the boiler to the drive cylinders oi the locomotive and located in such main is a gate valve 21 normally open and adapted, when closed, to cut of? communication between the steam space of the boiler and the drive cylinders. Connected with the casing of the gate valve 21 and projecting outwardly therefrom-is a substantially shaped yoke 22 having the interconnecting; member thereof formed with an opening alining axially with the bonnet of the gate valve to receive the stem 23 of the gate. Fixed upon the stem 23 Within the yoke 22 is a disk 2%., while encircling the stem between the disk 2% and the interconnecting; member of the yoke is a coiled expansion spring 25 adanted to slide the gate to closed position. The outer end oi? the stem 23 is bent at right angles to itseli as at 26 and iournaled in such bent portion is a roller 27 normally resting against one face of a sector 28 keyed upon one end of the shaft 18 normally disposed in the pat oi movement of the bent end 26 oi the stem 23 to hold the latter against sliding movement under the action of the expansion spring; 25 whereby the gate is held nor madly in open position. The brake pipe or train line air pipe of the motor car or train is indicatul 29 and located in such pipe and normally closed is a gate valve 30 havthe end or the stem 31 thereof bent at right angles to itself and formed to provide a tooth 32 meshing with a worm 33 fast upon the other endot the shaft 18. When the circuit the shaft 18 is revolved through the action of the worm in and worm wheel 17 and in the rotation of the shaft 18 the sector 24 is out of the path of the bent end 28 of the stem 23 whereby the spring reacts and slides the sate of the valve 21 to closed position, thereby cutting 0d communication between the steam space of the boiler and the enriine cylinders. Simultaneouslv with the swin e: of the sector to release the gate the v "e 21 the worm 33 in engagement with the Wo f. 32 the stem 31 of the ate the valve slides the gate of the last- Ill iiZlElllllOllSill valve to open the train line air pipe and so reflects a reduction of pressure therein whereby the brakes will be applied The shaft 18 also controls connected in series in the a comprises 4; secured to and in- 35 carried by the easnrojecting outwardly i' n the stem. 31 of the ct 36 lined to and normally en-.

is closed and the'rnotor l4 energized 1 lower end thereor movement bar 56 mounter gaging the stationary contact 34 and adapted to ride oil of such stationary contact in the outward movement of the stem 31 under the action of the Worm 33 to break the circuit 15 of the motor i l succeeding the opening of the valve 30 and closing of the valve 31 whereby the motor will be deenergized.

37 designates a substantially rectangular base plate suitably secured to the under structure of the motor car and disposed in a horizontal plane. Uprising from the base plate 37 adjacent to one end thereof and spaced apart longitudinally of such plate are bearings 38 and mounted Within the bearings and capable of sliding movement therein is a plunger rod 39, While upstanding from the base plate 37 adjacent to the opposite end thereof and spaced apart longitudinally of such plate are bearings 4-0 in which is mounted for sliding movement a plunger rod ll. Secured to the confronting ends of the plunger rods 39 and ll are contacts 42 connected in series in the circuit 15 and adapted to close such circuit when in engagement with each other. lineircling the plunger rod 39 between the bearings 38 is coiled expansion spring 43 having'one end abutting; one of the bearings and the opposite end in engagement with a shoulder id formed on the plunger rod adapted to limit the movement of the plunger rod under the action of the spring 43. remaining end of the plunger rod 41 is a disk 45 and spaced apart from the adjacent bearing 40 and interposed between such disk and bearing is a coiled expansion spring 46, While formed on the plunger at the opposite side of the adjacent bearing 40 is a shoulder 47 adapted to limit the movement the plunger rod 41 under the action of the spring 4:6. Depending from the lower sur- "face of the base plate 3? at the last-men" tioned end thereof are vertical posts 4:3 spaced apart and connected with the lower extremities of the posts 4% is supporting an opening alinine;

plate 19 formed with end with an opening formed in the adjacent the base plate 37 and journaled in these lining" openings and capable of rotation herein is a e e-m equipped with an arm o proiecting at right angles to the shale and lying. normally. in ie plane at right angles to the path of travel ofthe car. Fast to the upper end of the shalt 50 is an eccetrio 52 erigagrinnthe disk Fined to h shaft 50 immediately abo late 49 isa ratchet whee. tne teeth oft-he ratchet "wheel 53 acting to hold the shai t 50 against tur in one direction. Also fiXQOi the shaft 50 above the ratchet Wheel 53 pinion 55 meshing with the teeth oi. l for sliding mo ent l in suitable hoizontally alining guides is: n

Til C Formed on the vertical shaft 50 having the ried by the posts 48, a coiled expansion spring 57 having one end fastened to the rack bar and the opposite extremity secured to a bracket depending from the base plate 37, such spring acting through the medium ofthe rack bar 56 and pinion 55 to hold the shaft 50; against turning movement in the opposite direction.

In practice, when the motor car passes a danger signal, the arm 51 impacts against the adjacent edge of the obstacle plate 8 and so rocks the shaft 50 against the action of the spring 57. In the movement of the shaft 50 under the action of the obstacle plate the dent to the engagement of the contacts 42,

is eliminated.

From the foregoing description taken in the accompanying draw-" connection with V ings, the construction, mode of operation and manner of employing our invention wi ll be readily apparent. It will be seen that we have provided automatic stopping mechanism for motor cars whereby the propelling power ofthe motor car will becut 0E and fine ourselves to the precise the air brakes applied car running by a danger signal and wherein the car carried mechanism will be automatically. cut out of service immediately succeeding the cutting off of the propelling power and application of the brakes. In the present instance, an audible signal 58 in the form of a bell is connected in parallel with the circuit 15 so as to advise the engineer or train crew of the operation of the stopping mechanism. While we have herein shown and described onepreferred form of our invention by way of illustration, we Wish it to be understood that we do not limit or condetails of construction herein described and delineated, as modification and variation may be -made within the scope, of the claims without departing from the spirit of the invention.
