PATENT OFFICE ANGEL ZUBERO AZCAIR-AY, or HABANA, CUBA RAILWAY SWITCH I A pplicetion'flled, .Tune 27, 1929, SeriallNo. 374,083, and in Cuba June 18, 1929.

Thisinvention refers to rail-way switches, v

andhas for its main object, the provisionof a device of this kind, which may be operated from the train itself while traveling, said de- 5 vice being very simple, "of easy operation, and

avoiding the necessity and cost of aswitchman.

Another advantage of this invention is to H provide a railway switch of substantially au- 16 tomatic operation, the structure of which,

besides offering complete safety in switching, is not susceptible, on account of its simplicity, to derangements, interruptions, or breakage. 1 p

Y r

j Referring to the figures of these drawings, inFigure 1, is showna section of a railway, details ofwhich are designated by 1 and 2, witha branch, the rails of which are'designated by 2 (extension of the rail 2) and 3, said branch being connected 'to the main track by a switch 4, the points of which are secured to a narrow switch cross plate 5. To the ties'10, of the track on both sides Fig. 6v is a vertical. cross section in detail,

of same, are fastened the ears 6. provided with bores, through which pass the rods 7 and 8, the rod 8 being divided into twosections 8 and 8 connected together by a Gardan union 11 so as to be extended along the outer, rail of the branch track. a

To the rods 7 and 8 next to the plate 5 are securedcthe hanging brackets 12 and 13, having slots 12 and 13' on their lower ends, through which are mounted ,the'stems 14, which bear on their ends a rocking cross-bar 15 placed under the plate 5 in a recess 15" positioned between adjacent ties 10, and which bar is also-provided with slots 15 which are slidably engaged with, adjacent stationary guide-and support bars 16,-suitably secured to the walls of the recess 15,.' On the portions of said bar 15 abovethe slots 15, and on each side of said bar, are pivoted the latch fingers 17, each forced downward through a leaf spring 18 and which latches engage the guide bars 16, when the'bar 15 is rocked, andare thus placed on each end vof the respective slot 15, said fingers being held in place by stops 19. V

From the middle of the switch plate 5 de-- pends an ear 20 and thereon is hinged by stem and slot connections an arm 21, the lower end of which is engaged by a like connection to the bar 15,.this arm 21 being pivoted to a bar 21 also fastened between the walls of the recess 15". a v a a To the rods '7 and 8, and to portions of the same in advance of the switch are secured as shownin the Figures 1, 5,8 and 10, downwardly bent arms 22, the ends of which are en a ed throu h slots 23 )rovided in the O D b 7 1 maintain the Heads in a slightly elevated position observed that when the switch is closed the engagement of the corresponding arms 22 with the blocks 23 is such-as to normally above the upper surfaces of the rails Further along from the crossing, a portion of the rail of th e main track 1 and the rail 2 of the branch, are cut, and movable blocks 26 are housed therein, and provided each with a head which tse e essitebl s a made in the same shape as the respective rail and having placed on one side of said block 7 azprotective plate 27 secured to the cut ends 1 piece 26, IS'lIOllSGd in a recess 29 'provlded 1n of each railg by rivets; andon theopposite side, another plate 28 secured in like manner to the cutends of the rails, and having a recess 28f, theobject"off whichwill be explained he dl g'a i Y I l The lower part of each block or operative the ground, between twoof theties 10 whereonthe said rails bear and presents a slot 26" through whichthe looseend of an 'adjacent bent'arm is engaged.

The'locomot1ves,'or tractors of trains, or other rolling-elements, constructed tolrun on rails provided withfswitches, similar to] those which are the obj ect of this invention,

blocks or operative elements 23 and'26 r Th pperation of this switch is'a's explained in the following: 1 p

' Assuming thata train is travelling over the trackwhich'is shownin' Figure 1, and near; ing thecrossingfitted with the switch, which is alsojshown in "same, the block 23 on the left: is in" a depressed position, under the action.

of-thjejarm 22, as indicated by full lines in Figures 8 and 10. In' such a position, the

maintrack composed of the rails 1 and 2, willl be open, and the branch line formed by the;

' rails-2 and 3, closed.

- If thetravel of the trainis along the main track, upon verifying that same is open, by the [depressed position"oftheblock 23 on the;

left side, we have only to take the main track,

' the trainv continuing in its forwardroute.

'But if itib'e desired to follow along the branch tracln -instead ofthe main line, we

haveonly" to operate the hand wheel 33, on

the right,'upon arrival at the blocks 23, so that it engages the blockat the right, and

upon engaging the head 23 of same, for this,

, purpose, it forces same downwardly, [and thusthe arm 22 will be moved downwardly,

giving a swift movement to the rod 8, and

its section 8', which will drag the cross bar a 15 with it, by its connection withlthe arm 13, which bar will slide over the guide rods 16. The guide rods 16 will be engaged by the latches 17 upon arrival at the end of the correspondingslot so that the bar 15 will then adoptthe position shown in dotted lines in the Figure 6, and thereby causing the movement of the rod 7, due to its engagement therewith, by the arm, 12, the blocks 23 and 26 on the left thereby being in an abutting position, and the blocks 23 and 26 on theright ina depressed position, the switch plate 5,

being driven, -due to its; engagement by the linl; 21; with; the bar 15, and the,switch 1, be-
