Specification or" Letters .Patent `To all whom t may concern.'

Be it knovvn that FRANK M. Ferentino,

a citizen of lthe United States, residing at Pl'liladelphia, in the county of fhilaflelpliia anrlState of Pennsylvania, have invented. `certainnevv and useful. inproveinents in Railv\'ay-SWitches, of which the ollovvingis a specification.

Theobjeet of my inventionis to provide a railway switch novel, simple and ellicient construction. having provision, first, whereby itaviil he impossible for Wheel flanges-to 'pass between the main track rail and .thesivitch tongue when the latter is in position toclirect the wheels from the main tracl'; secondly, whereby in one position ot the mechanism, the side Walls of the main track groove will he continuous and uniuterruptcfl. ,at .the junction of the main track groove and the branch groove, and, in anotherfposition of the mechanism, the side Wallso'the branch groove will loe continuous and uninterrupted at the junctiony ol the branch groove and and, thirdly, whereby various novel and aflvantageous results are attained.

My invented devices consist o the ele4- ments and the eoinbinationsof their; heroinafter fully described and claimed.

In the accompanying drawings, iilustratmy invention:.Figure l, is a plan view Yot' a railway switch embodying iev invenzr tion. "Figf is a plan view ol the two switchtonguesy removed from the switch structure. Fig. 3, is a longitudinal section, on line of Fig. 1. Figs. e, 5. (Saud 7 are transverse seelions through the switch structure7 on lines -t-h SM5, (3 6 and 7-7, respectively of Fi 1. Fig. 8, is a transverse section, on liuc 8-8 of Fig. 3. Fig. 9, is a horizontal section through a 'portion of the switch traine, she *ing the operating devices for the tongues and adjuncts. Fig.. l0, is a perspective vieu' otono ot' the earn shafts. Referring to the drawings, 9 designates thc/.traine of the lswitch structure having the main ytrack ,groove lOuand the branch track groove 11 formed therein, the groove. l0 and 11 being adapted to receive the car wheel flanges in the usual manner', the branch track groove l1 cominonicating` with the main track groove 1G. @n ootsi of the grooves Yit" and l1 are 'the portions 12 and 15%., and on the of the grooves 10 anti; il ari the oortions "4. and 15, respectively, the guard. `portions Application le.

lit an l 15 termine1 contiuuations of each other on one side of the branch groove 11 and the guard portion 1l and tread portion 1&3 forming a point portion 1(3 01-1 the other side oi the groove 1l. and `fionauiting the grooves lO 11. u

lfVithin the ,grooves 10 and l1 are tivo tongues 17 and 1S, respectively, each hav-- ing a rounded end portion 1S) fitted to turn in. a socket 2O in the Jranie 9 in a manner to permit the pointed cnil of the tongue to be raised and lowered into and troni the path of car 'Wheel flanges. has a vertical face S21 which,`When the tongue is ra ised, as shown, connects the sirle of the point portion lo' forming one wall of brauch track groove 1l. with the side ot tread portion 12 forming; one wall ol he main track groove 10. so that when the tongue 17 is up and the tongue 1H cioivu, as shown, the `tice 21 `vill direct wheel flanges frein the main track zgroove l0 to the branch groove 11, and the side Walls ot' the lavo grooves 10 and 1l will forni uninterrupted continuations oi2 each other.

The tongue ,18 has a vertical face 'L2 which. when the tongue is raised, connects the side oft' the point Vportion 16 forming one 'all olx the nfiain track groove. l() with the side ot the ".arel portion 14 forming the saine or the main track af roove l0, so that 'when the tongue 1B up and the tongue 1.7 is clown, the 'face 2L will extend across the branch track `groove l1, and both side Vwalls of the Imain track groove l() will lic continuous anti uuinl'mruptofl, i'irevel'rting wheel flanges troTn entering the branch track groove 1l from ve main track groove 10.

The top ot point end of the tongue lie mi@ 1,7, is sliggatly helovvv the top ot the tread poru tion V12 anilL ii'ioint portion lo, so that car Wheels will not hear upon the tongue 17 when it is raised, the who being supported by both the tread portion and point 'por ion 16 in passino' over the main tract: groove 10 to ausl from the branch-track.

The pivoted end oi `each tentare-is vided. with longitudinal groove is inclined upwarilljvi and a top ot the point enti of the tongue., torn ot thev groove always being* heloiv tl?. path. Wheel at the 'pivotefl en@ the tongue. Flach tongue is fitted. to sli tical" between two 'walls of the :trane ien each Io'rms a contini tion ot' the floor por,

The tongue 1l" is .flown ita upper tions of the grooves beyond the ends of the tongue, and the 'licor of the main track groove is provided with a point portion 24 which extends between and separates the di verging faces 21 and 22 of the tongues 17 and 18, respectively.

To operate the switch, the tongues 17 and 18 are raised andlowered in alternate succession, and when the tongue 18 is raised, an uninterrupted main track Oroove is presented, and when the tongue 17 is raised, an uninterrupted branch track groove is presentedY 'To thus raise and lower the tongues 17 and respectively. The sleeves 27 and 28 are provided with upper and lower cams 29 and 30 which, engage the adjacent ends of the switch tongues 17 and 18, as shown, and the cams 29 and 30 of the two sleeves are so related to each other and to the tongues that when the sleeves are turned in the direction ofthe arrows in Fig. 9, the tongue 18 will be raised and the tongue 17 will be lowered, and that when' the sleeves are turned in the reverse directions, the tongue 18 will be loweredand tlietongue 17 will be raised. The sleeves 27 and 28 are provided with coacting gear wheels 31, so that when one sleeve is turned in yone direction the. other will be turned in the reverse direction, as

indicated by theJarrows in Fig. 9, and engaging the teeth of one of the gear wheels 31 are the teeth of a gear rack 32 which' is mounted'to slide in theframe 9. The rack '32 has an upwardly extending slotted lug 33, and extending into the slot in the lug 33 is a pin 34which projects from an arm 35 `on a head 36`which is rotatably, mounted on a pin or shaft 37 within thev box 2. 36 has anopening or socket 38therein for the reception of a bar-or other device, by means of which the head 36 may be turned, and the socket 38 is exposed through an opening 39 in a plate or cover 40 for'the box 2, to

. permit the insertion of the o erating device.

It will be readily understoo that when the .head 36 is turned, the pini34 will engage the lug 33 and slide the rack bar 32 which will turn the sleeves 27 and 28 for the operation of the switch.
