Patented May 9, 1922,
Application filed February 7, 1921. Serial No. 443,292.
To all whom. 2'25 may concern This invention relates to improvements inspeed circuit controllers, one object of the invention being the provision of a centrifuge device adapted to be used in conjunction with a train control system either of the intermittent ramp type or induction type, it being carried upon the moving vehicle and being brought into play toprevent the train from exceeding a predetermined speed after a receiving a caution signal.
A further object of this invention is the provision of a centrifuge device which is so constructed and arranged that should it I be broken it vwill immediately produce a danger condition or be disposed from the circuit so as to reduce the speed of the train.
A still further object of this invention is the provision of a-vertically disposed centrifugal device operating a sleeve against the tension of the spring which in turn is operated upon by other springs to normally hold it in such position 'or to assist the action of the governor so in case the governor should break the contact will be made.
In the accompanying drawings:
Figure 1 is aview in elevation and partly in section of the complete device.
Figure 2 is a section taken on line 2'-2 of Figure 1. 7
Referring to the drawings, the numeral 3 designates the supporting base which carries a casing 1 adapted to be closed by'any desired means, said casing is provided with the bearing 5 witha shaft 6 which has fixed thereto the support 7 for the twopivoted arms 8 each one of which is provided with a ball or weight 9. The two links 10 are pivotally connected to the arms 8 and to the slidingsleeve 11, said sleeve being held against independent rotation by means of the pin 12 and slot 13 of the shaft 6. A spring Mbears against the underside of the sleeve 11 and the tension thereof is adjusted by the lock nut 15 upon the threaded portion of the shaft 6 so as to-normally hold the sleeve 11 upwardly with the contact 25 to 2? closed or in any desired manner to which the device may be placed.
Above the sleeve 11 is a cross head 16 which with the disk 17 clamps the disk 18 of lnsulation ,therebetween so that the openings 19 will fit about the four studs or pins 20 whose light springs; 21 mounted thereon normally bear against the upper side of the disk 18 to hold the same downwardly.
The crosshead 16 is free to move up and down on the shaft 6 but is held from rota ingby the studs 20.
' The bolts 22 and 23 connect the respective spring contacts 24 and 25 to the disk, said contacts cooperating respectively with con tacts 26 and 27 of the L-shaped brackets, which in turn are connected 'to the conductors 26' and 27', said brackets being attachedto the casing by the strips of insulation 28 and 29 respectively, so there is no ground. The flexible conductors 30 and 33 are connected to the respective contacts 24 and 25 andby means of the respective terminal connectors 31 and 34: are connected to the respective conductors 32 and 35, which particular arrangement may be varied as circumstances require, it being here shown and intended that when the device is at rest, the contact at 25 and 27 will be closed 'while that at 24: and 26 will be open, the
of the spring 14 so that the disk 18 is lowered opening the contact at 25 and 27 and at the proper time closing it at contacts 24 and 26.
What I claim as new is:
1. In a device of this character, the combination of a support, a shaft journalled therein for rotation, a spring adjusted centrifuge device mounted thereon, a sleeve connected to the centrifuge device for sliding movement upon the shaft, a disk of insulation carried by the sleeve, cooperative contact points carried by the disk and in the path thereof, means for guiding said sleeve and holding it against rotation, and resilient means opposing said disk in opposition to the spring of the centrifuge device.
trifuge device mounted thereon, a sleeve connected to the centrifuge device for sliding movement upon the shaft, a disk of insulation carried by the sleeve, cooperative contact points carried by the disk andin the path thereof, a plurality of posts disposed in the support and upon which the said disk of insulation slides, and a spring mounted on each post and engaging the disk of insulation in opposition to the spring of the centrifuge device.
In testimony whereof I uflix my signature.
