th same, reference being had to the accom- Y cons a ying. drawings, and

My invention relates to im rovements in electrical signaling apparatus ut more speciflca yto a special construction and arrangementy of contact carried by the train and adapted to engage the conductors of a block system which conductors may be sup orted on polles or placed on the ground. n the ylattercase they would of course be insulated frdm the earthin order to maintain the signalin circuit intact and prevent the grounding o the current.

special feature of my improvement consists the fact that my improved contact is ructed `'and arranged to yield freely to compensate for the swaying of the train in eithen'direction, the construction being such that perfect contact may be at all times maintained regardless` of this swaying movement.

Having briefl outlined my improved construction as wellas the function it is intended to perform, I will proceed to describe the same in detail reference being made tothe accom anying drawing in which is illustrated an ein odiment thereof.

In this drawing, Figure 1 is a view illustrating my improved yielding contact shown in connection with the signaling conductors supported above the ground. Fig. 2 is a View looking toward the left in Fig. 1 showing the signaling conductors in place but with their supporting apparatus removed. Fig. 3 is a cross section taken on the line 3-8 Fig. 1. Fig. 4 is a view showinor in detail the manner of snp orting the overhead conductors shown in igs. 1 and 2.

Referring first more especially to Figs.-

' and 2 of the drawing, let the numeral 5 designate a train or a car thereof upon 1s mounted a yielding contact which 1n this 1nstance .is composed of two arms 6 and 7, -a

guide rod 8 and of a torsional spring 9.

ait 10 jour- Around the shaft 10 the spring 9 .is s irally arranged oney extremity of the spring eing connecte The arm 6 is made 'fast to a s .with one of the supports 12 as shown at 14, While the other extremity is made fast to the shaft as shown at 13, the arrangement being such that the tension of thel spring normally acts to throw the larm 6 outwar y toward the conductors 15 of thel block system. These conductors are suitably supported. In this particular instance an arm 16 is pivotally mounted at 17 on a bracket 18 made fast to a pole or post 19. The downward movement of the arm 16 is limited by a support 20 which in this particular instance is shown flexible though it is evident that the arm 16 may bel supported in any suitable manner.

The arms 6 and 7 are ivotally connected or jointed at 21, while t e lower extremity of the arm 7 is pivotally connected as shown at 22 with the vertically disposed rod 8 mounted in guides 23 secured to the car 5. It is evident that by virtue of this construction, if the car sways or tilts toward the left, the spring 9 will act to throw the contact arm 6 outwardly and thus maintain perfect contact with `the conductors l5 while if the car sways toward the left, the Contact arm and its connections 6 will yield sulliciently` to compensate for said movement 'while by virtue of the flexible connection 20 between the arm 16 and the post 1.9, the conductors 15 may change their .relative position to facilitate the operation of the device.

In Figs. 4 and 5 a special arrangement is illustrated for supporting the c .ductorsi from the arm 16. In this case shoes or clamping'devices 24 arev passed arouiiid the conductors 15 and secured to hangers 25 which are connected with the arm 16 in any suit-- able manner. As shown in the drawing the conductors are curved u nvardl indicated by the dotted lines in Fig. 4 and also as indicated by the position of the conductor 'l5 in Fig. 5 thus locking the conductors against .pivotally connected with t a band member 28 engag.` I ingathe conductorsxwhich are supported -ona stationary shoes. In Fig. 6 another form of movable contact is illustrated com e car`5 asshown at`27 and having supports.- The 'arm' 26 is s ring-held and spring-actuated by means `o the torsional spri 9 the same as thearm 6in Figs. 1 and 2. :In igs. 7 and 8 lstill another form of construction is illustrated. In this/pase the contact connected with the caris'co'mposed of two members 32 and33 pivotally connected at 34. vThemember 32 is mounted4 in a bracket 35 secured to the car 5L .f The arm v 33 is held jup against the contacts 15 by 32 as shown direction, the tendency of the sp means of a n A at 37, andbent around the joint 34 'to engage the yarm 33-,u1iderneath thus forming a yielding supportg i In this instance the conductors k15 are .xnountedon a statio`nary support 38, It isassumed'iii allthe constructions heretofore described thatv the signaling conductors 15 4are insulated from the ground inL an 1 suitable: manner. As'

shownin Figs. 7 an 8 the arm- 32 is' supposed to have a limited revolublemovement mits bearing 38. To the upper extremityl of thisl arm 32 is attached a cross piece 39 whose extremities onV opposite sides of the, arm, 32 are lacted on by 'springs 40 so .that in the event that the arm 32 is turned in either will be to return it to its normal posit1on.j'.In the views designated Figs. 6, 7 and 9 one ofthe 'track rails is indicated and designated 41 in order to show that the supporting means for the signaling( conductors l restt neai` v-thel level of the trac A y.
