' vertical position, and the top 2 of said box 2O is connected in lile,mannerat' its other end at joint 21 with bar-22, which is of greater length and'which in'turn at its other end is pivotally connected with the Aupper end of upright 23. Between its ends bar 22 is bent in 'sucha manner that that vsectionlies close tothe vertical ortion of railX. Bars 20 and 22 are of suclh a length 'that when upright 19 stands in a vertical dpositionthe oblique angle formed by 20 an 22 at joint 21 projects above the top of rail X, and when upright 19 is swung down in direction of train movement said bars 20 and 22 will lie at joint 21 on a level with the top of rail X. From the inside of the upper end of upright .19 rojects an eye-29 to which is attached 'a ro 18 attached at its other end to rod 15', which, as;- has been described, is connected'w-ith plate 1 0 in sucha manner that when upright 1 9 isverticalsaid plate 10 will have swung, in a j direction opposite to that of train movement,

onv its 'vot 11 to a position practically paral-` lel wit the bottom of box 1. To vthe saidother enduof 18 is 'also attached rod 24,.'at-l tached to'the other end of which is chain 25 leading around wheel 26y and u through signal tower B to the inner end o danger signal arm 27 in such a manner that when upright' 19 is vertical, said arm 27 will bein a verticali) position, or not in use. Thus it will be seen-l that when upright 19 is swung: in direction of train movement on its pivot by the depress-` ing of bars 20 and 22, at joint 21, the plate 1,0

(Fig. 4) in box 1 will assume a verticalfposition thereby raising one end of cover 2 and also danger signal arm 27, Fig. 1, will assume a horizontal position and show a danger s i nal to approaching trains 1n connection w1t lsafety signal arm 28, which is ordinarily displa ed alone. To eye 29.is also attached one en of'a rod 17 which extends in a direction oppositeto that of train movement to the beginning of the preceding block where its',v othercn is attached -to a chain 13 and its? connections (described in connection with. Fig. 4) in such a mannerl that when upright4 19, lin any block, is swungin direction of 'train movement on its pivot, as has beendey scribed, the late 3 (Fi 4) in thepreeeding block track ox A wil be pulledfrom the lowered, while by means of rod 1'5 connected to plate 3 in said box the upright 19 of the said preceding" block device will be swung to a vertical-position, thereby raising the joint 21 of ,rods 20 and 22 above the level ofthe rail X and through rod 1S etc. dro ping lb ook danger signal arm 27.of said preceding to a vertical position out of use. j

The construction of Fig. l'lias already been described inthatorI Fig. 2.

In Fig. 5 is shown a sectional end view taken on line 5-5 of Fig. 4 and showing plate 10, rollrfl, rod 12, etc.

Fig. 6 represents the train section'C, or

that portion of our improved sto", device which is attached to the train itse f, being preferably fastened to the locomotive at the "rear right hand side o1" the cow-,catcher and thus adapted to travel over successive track boxes A. This section C comprises a plate 30, attached to the en ine, secured to the lower end of which is cy inder 31, and to the upper end cylinder 32 spaced apart'from 31 near the center of plate 30. Cylinder 31 is pierced by a bore permitting of movement therein of rod 3 3, w lich rod terminates at its lower'end in a foot 35., A collar 34 near the upper end of rod 33l permits' the rod to project far enough below the cylinder 31 to allow the foot 35 to come'in contact with and be fpushed up by the cover 2 of a track box A when any part ol said cover is raised (best shown in Fig. 1) while another collar 34 near thev lower end vvof rod 33 prevents said rod from being pushed up through the cylinder 31'more than a required distance. Cylinder 1,32 is also ierced by a central 'bore terminating near t 1e tolp in a cylindrical chamber 46 with a funne shaped bottom. Rod 36 moves in the bore in cylinder 32,.extending 'below the same until in close proxmity to the upper end of rod 33 when said rod 1s in its lowest position and terminatingl at its upper end in a head 37 itting in the funnel-'shaped 4bottom of chamber 46. From the center of this head '37 and integral therewith projects a vertical rod 38' which is encircled by a spiral spring 39; spring 39a rests on the head 37net. the bottom and'- at the top bears against a tfop member 47 which closes the chamber 46. Thus the spring 39 normally tends to keep the head 3-7 in its seat While a recess 40 insaid top 4T over rod-38permits said rod to move upwardwhen theV head 37 is forced out .f-.fits Seatby pressure on the lower end of the su()l rod" 36'.' VNear the bottom ofthe cylinder 3 2 a'pin .42 passesin and pressedy against the 'rod 3 6`by a spiral sprang 43; in rod 36 just below the point wherethe .ino/12 abuts saidv rod, whennlits normal or owered position,

is Vanannular recess 41 into which the said .pin 42 is forced by the sprin 43 When the rod 36 is pushed upwards, and t us said rod can.

not again dropdown to its normal position until the pin 42 ispulled out of saidrecess41. Through the wall ofthe cylinder 32 near the top slants al bore 44 opening into the 'funnelshaped bottom of chamber 46, the head. 37 ol vthe rod 36 thus closing this bore 44when .said head rests in its seat.

As tlie trein enters tlie block X', the Wheels press down thus'swinging 1Q on its pivot; through this swinging oi' i9 and tile rods i8 and 15 connected thereto, plete i0 is swung up in track box A", raising the cover i7 swing- 4 ing i9 of the next bioolf` 'to a vertieei position und tiius 'ratisin tbev corresponding rod 22 above tbe top o? tl'ie rail in seidI next' bleek.
