RAILWAY swrfrci'a.

To all 'whom it may concern Be it known vthat I, IGNACIO ARTEAGA, a,

citizen of Mexico, residing at San Antonio, in the countyV of Bexar 'and State of Texas, have invented certain new and useful Improveniente inlailway Switches,.of which 'i the following is a specification.

the air brake systemk when the device is installed on cars using air brakes.v

(Fig. 9 is ay section enlarged' on the line 94-9of-Figj8. Y v p f- The improved apparatus may be installed in connection with trolley lines A of the ordinaryconstruction, or to the split switches of steam roads, but for the purpose of illustration is shown applied to an ordinary trolley line lin which 10-11 represents the main line rails 12-13 the siding or switch rails, 1/1-'-15 the frog portions, and 16 the switchpoint the latter pivoted at one endtothe frog member 15 asl shown at 17, and reduced at the vfree end to engagein a relatively long recess 18 in the inner face of the A curved rail portion of the frog-member. These parts are of the usual construction.

Theties are represented at 19, and mount-` ed for rotation through .certain of the ,ties plate 21 at one end and a gear 22- at the other end. y

Attached to oneface of one of the ties19 at a suitable distance from the switch point 16 are spaced keepers 27, Vand slidable through these keepers is a gear teeth 29 in its lower face in constant engagement with the gear 2 2 and with glateral projections -30 at the ends, the outer faces of the` proj ections'being reversely .bevelled, as represented in Figs. 1 and 7. a

A vportion of a conventional Itrolley'car body is represented at 31, with a portion of themotormans platform` at 32 and one of thg trucks'at 33 mounted on the'tracks 10 an11.f'. Attached to the -frarnefof the truck 33, at eachsideare `guide brackets 34, and supported for vertical movement through each bracket is astandard 35each standard having a head 36 and a spring 37 operating to maintain the standard yieldably in its kupper position. l At its lower end each ofthe standards y3 5 is provided with an enlargement 38 having bearing roller 39 and la downwardly projecting-lug L10, the lugs .having reversely in'-` Aclined orybevelled confrontingfaces to Aen-` gage the bevelled face 30`of the bar 28 k"as hereafter explained.

The rollers yare adapted to bear upon the head yor tread portion of the rail and the projections 40 extend below the lower line of therollers when the standards y35 are `depressed against the resistance ofykthe springs 37.

bar 28 having l lhen the improved apparatus is employed in connection with ordinary trolley lines, or those without air brake devices, the arrangement shown in Figs. 5 and 6 will be employed for actuating the member 28, and when employed in connection with lines having air brakes, the arrangement shown inv Fig. 8 will be employed.

The arrangement shown in Figs. 5 and 6 comprises brackets or hangers v4l attached to the lower face of the platform 32, one near each side and each carries a stub shaft 42 on one end of which a small gear 43 is mounted and a groovecl cable pulley 44 011 the other end.

Attached to each of the brackets 34 are cable guide sheaves 45, one at each side, and attached at one end to each of the pulleys 44 is a pull cable 46, the latter being divideda-s it approachesthe sheaves 45 and passed thence over the sheaves to the head i member '36 of the standards 35.

Slidable through the platform 32 are operating rods 47, one for each of the gears 43, and lpreferably square or other form than round to prevent them from rotating and each with a head 46 to be engaged by y the 'foot of the motorman. -Each rod 47 is enlarged below the platform and provided with a spring 49 means to maintain the rod yieldably in upper position with the enlarged portion against the lower face of the platform.V The enlarged portions of the rods 47 areeach formedwith gear teeth in constant engagement respectively with the pinions 43. By this arrangement it? is obvious that either one of the rods 35 may be depressed at the will of the motorman, to dispose either one of the bevelled projections 40 into the paths of the bevelled faces 30 ofthe member 28. 1 v

vWith a car equipped as shown in Figs. 5 and 6, when approaching' 'a switch,`if Athe point 16 is set for the main line andthe car is to pass along the main line no attention is 4paid to the operating mechanism. It however. the car is to pass to the siding or switch track, andthe point 16 is set for the .main line, as shown in Fig; l., the motorman depresses the rod 47 at the left and thus correspondingly depresses the rod 35 at the left through the action of the pull cable 46 atA the left. and vcauses the roller 39 at the left to engage the ball of the rail 1l and the bevelled projection 40 associated therewith to'exteud into the path of the bevelled projection 30 of the member 28 and throw the latter over to the right and cause the rack 29 to engage the gear 22 andoscillate the shaft 20 and thus cause the rods 24 and 26 to move the switch point into openposition 4and guide 4the car upon the siding or switch track. i

It the switch point lGVis open the member 28 will be disposed with the bevelled member 30 adjacent the rail l() and if an approaching car is to continue along the main line, the motorman depresses the operating rod 47 at the right and thus closes the switch point by causing the projection 40 at the right to engage the bevelled projection 30 at the right end ofthe member 23 tocreverse the motion ofthe shaft 20.and correspondingly reverse the motion of the members 24 and 26 andfthrow the switch point into closed position, as will be obvious.

Thus `the motorman can" throw the switch point in either direction without leaving his platform. i

If the car is provided with air brakes the construction shown in Fig. v8 will be employed whereby a 'portion of the 'compressed air of the brake system will be Vutilized to operate the members `35 and their attachments.

In the modified construction'the mechanism attached to the platform 32 and the guidesheaves 45 will be dispensed -with and the head member 36 changed into piston head form as shownat 50; in Figure '8f port an air cyl-inder 52 in Whiclrthe` piston head 50 operates. The members 35, 38,-39

and 40 are'the same in thermodified strlrctu'e and operate in the samemanner.

Two of the cylinders 52 and their atta'c'hments will be' employed, one 'at-each'side, corresponding tothe foot actuateddevices shown in Fig. 6, but one set only is shown for illustration. f

Located upon the platform V32 are valve devices one of which isindicated at 53, and each preferably provided 'with an operating rod 54 extending to a point convenient to the hand of the motorman and provided with 'an operating handle 55.

' An air conductor tube 56 from the compressed air cylinder of the air brake system, not shown, leads into the valve casing 53 while another air conductortube 57 leads from tlic'valve casing 53 kto thecylinder 52. The valve members 53 are preferably'` of the three way form, "as shown in Fig-9, so that the airinay be readily exhausted' from the cylinder 52 afterthe operation of the mechanism, to permit the spring-37 to aubomatically vreturn thel member 40 to the initial or inoperative position.

By this arrangement the motor man may depress either one of the members 35 and produce thel same results as when the mech- The-preferred embodiment of th-#Neuf f'4 tion is disclosed in the drawings and set 'forth in the specification, but it will be understood that any modifications within the scope of the claimed invention may be made in the construction without departing Jfrom the principle of the invention or sacrificing any oi' its advantages.

Having thus described the invention what is claimed is 1. In a railway switch operating device a standard adapted to be supported 4for vertical movement relative to a car truck, a

spring holding said standard in elevated position, a shoe member carried by said stand ard and including a projection having an inclined face and a seat for a guide roller, said projection extending below the line of the ball of the rail on which the truck travels when in one position to engage a Switchpoint actuating mechanism, and the roller to engage the ball of the rail and limit the downward movement of the standard, and means under the control of the driver of the car to depress said standard against the resistance of said spring.

2. A railway switch operatingr mechanism comprising a bracket device adapted to be attached to a car truck7 a standard movable through said bracket, a spring operating to maintain said standard yieldably in elevated position, a shoe member at the lower end of the standard and including a downwardly directed projection having an inclined face and a seat to receive a bearing roller, said projection extending belon7 the line of the ball of the rail on which the truck travels, when in one position and adapted to engage a switch point actuating mechanism, and the roller to engage the ball of the rail and limit the downward movement of the standard, and means under the control of the driver of the car to depress said standard against the resistance of said spring.

In testimony whereof, I affix my signature hereto.

IGNACIO ARTEAGA.
