To all wiz/0m, it may concern.- y

l Be it known that I, J EAN F. WEBB, reside ing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Semaphores, of which the following is a specification.

My invention relates to certain new and useful improvements in semaphores, and it primarily seeks to provide an electrically-operated semaphore in which means are provided for presenting a blade-signal as well as a light-signal, and in its generic nature my invention comprises a supporting-frame, a signaling-shaft, carried by the supportingframefwhichv controls the signals, both blade and light, means for preventing the shaft from turning except in a single direction, means for locking the shaft from turning in such single direction, clectrically-controlled means for first releasing said locking means and then turning the shaft in one direction to `change the signals, and a casing for the oper ative parts of the apparatus.

he present invention primarily has for its object to Aprovide a semaphore apparatus of this character of a very simple construction which can be easily and cheaply manufactured and which will readily and effectively serve its intended purposes.

With other objects in view tofore been enumerated the invention also coinprehends certain novel construction, combination, and. arrangement of parts, all of which will be first described in detail and then bc specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which"- igure 1 is a perspective view of my invention complete. Fig. 2 is a similar view, the

than have herehousing being removed. Fig. Sis a face view of my lnvention, the housing-cover being shown open. F ig. 4 is an end elevation of my invention, the housing being shown in section. Fig. 5 is a cross-section taken on the line 5 5 of Fig4 3 looking in the direction yFig. 6 is a detail perspective view .of the signaling-shaft and its carried parts. Fig. 7 is a vertical longitudinal section of a slightly-modified form of my invention.

U Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the figures, 1 designates the signal-shaft, which is mounttrip-arm 10, having Vto the plunger or piston 17a 2C 2c and which are connected together at the top by a cross spacing-bar 18, as shown.

Mounted on the shaft 1 between the supports or standards 2 2 is a ratchet-wheel 3, having four notch-faces or teeth 3a arranged peripherally and ninety degrees apart, and the notches or teeth 3a are arranged in a direction opposite to that in which the shaft is designed to normally turn, andthe shaft 1 is prevented from turning backward by a pawl S, which is fulcrurned on a stud-bolt 9, secured to the support 2, and which engages the ratchet-wheel 3. yThe pawl 8 is held onthe bolt 9 by a pin 9, as shown. The pawl 8 and the ratchet 3`serve as a means for preventing rotation of the shaft in a direction reversely to that of its normalmovement. Secured by a set-screw 4a to the shaft 1, adjacent thc ratchet 3, is a collar 4 to which a second ratchet-wheel 5 on the shaft l is secured by a screw or rivet 4b. The ratchet 5 has four teeth 5a peripherally arranged and spaced ninety degrees apart, but facing in a direction opposite to those 3 on the ratchet 3 and facing in the same direction as the direction of normal rotation of the shaft 1. A

pawl 10, fulcrumed on a second studebolt 11,

secured to the standard 2, engawes with the ratchet 5 to prevent rotation of the shaft 1 in its normal direction, thus normally locking the shaft from rotation. The pawl 10 has a a bevel-edge 10b for a purpose presently understood.

Mounted on the shaft 1, adjacent the.

ratchet 5, and secured to turn therewith by the screw 4b,is a pair of disks6 6, spaced a suitable distance a art and 'oined by four cross-pins 6a 6a, as s own. ` T epins 6a 6a are set ninety degrees apart, as shown, and some distance in from the periphery of the disks 6 6 to permit passage of the operating-bar 13 between the disks 6 6. The bar 13 is secured of the electromo tor 17, hereinafter again referred to, and the said bar 13 is preferably constructed of brass IOC or other` non-magnetic material and is provided near its lowermost end with a hook 13a for engaging and operating the pins 6a 6a to turn the shaft 1 in the direction of the arrow.` The bar 13 carries a pin or stud 14 for en gaging the arm 10*L of the pawl 10 to release the ratchet 5 just prior to the time the hook 13 engages the pin 6 to turn the shaft 1 through one-fourth revolution, the stud or pin 14 leaving the arm 10 of the pawl 10 just afterv the shaft commences to turn, thus allowing the pawl to drop into contact with the peripheryof the ratchet 5 to en age the next ratchet-tooth 5 and prevent t 1e shaft turning through more than one-fourth revolution at each operation. As the bar 13 again drops to its initial position, as will be more fully understood presently, by reason of the pivotal connection of the motor 17 with the bar 13 the pin 14 passes over the beveled portion 10 of the arm 10 of the The pawl and drops to its initial position. barr13 has a second hook 13 near its upper end, which when the bar is in its lowermost position engages the stud-bolt 12 on the sup port 2, thus holding the bar from dropping downwardly too far and maintaining 1t in proper position to engage the pins 6 6 of the disks 6 6.. The bar 13 is connected at 16 to` the piston or plunger 17 of the motor 17.

The motor 17 which may be of any approved type of electric motor, is shown in the drawings as a solenoid magnetic reciprocating motor comprising a movable core or Vplunger 17 and the fixed core 17, the whole being surrounded by a casing 17, of inagnetic material,'to form an iron-clad housf ing for the motor. The casing 17 has extensions provided with apertures 17d 17d to permit it being miunted upon the cross-brace 18, where it is held in proper position -by the, pins or keys 19 19, as shown, to allow the whenever the bar 13 is raised to the limit of its movement.

The operating-circuit 45 has its terminals -45 45 connected to the winding ofthe motor 17, so that when the switch Sis closedthe motor 17 will operate to turn the shaft 1 through one-fourth of a revolution.

Secured to the standard 2 by bolts 34 34 is a bracket 34, to which a lamp-holder or ringl 33 is secured. A lamp 29, of the usual long-burning railway-switch ty e, is held in the holder 33, as shown, a smo re-bell 32 'being supported ove`r the chimney 30 of the lamp 29 by a rod 31, secured to the holder 33.

24 designates a collar secured to the shaft .1 by a set-screw 41, and the collar 24 carries a plurality of radial arms 24l equal in number to the teeth on, the ratchet 5 and arranged proaching train.

ceive the signal-plates 43 43, which are secured thereto by bolts 44 44, as shown. The blade 43 is arranged at ri ht angles to the blade 43, so that only one lade Will be visible tothe engineer at a time, the blade 43 being whiteto indicate safety, while the blade 43 is red to indicate dangen Secured to the post 2, over the standards 2 2 and the operative mechanism of my semaphore is a casing or housing 46, which has a door 46 in its front,rwhich door 46 is hinged at its upper end at 49 `to the casing and is slotted, as at 46, at its lower end to coperate with the staple 50 on the post 2 and is secured by a lock 51, as shown.

47 designates a Window in the door 46, which isfiit horizontal alinement with the lamp 29, and'a second window 47 in the back wal of the housing 46 to permit the lampsignal being seen by the engineer'of an ap- Suitable apertures 48 48, are provided in the housing sides to permit passage of the shaft 1, as shown.

So far as described the manner in which my invention operates will be best explained as follows: Assume the signal to be set at safety with the blade 43 visible and the transparent lcolorless lenses 28 in alinement with the lantern 29 and the apertures 47 47 in the casing 46 to indicate a safety-signal. N ow assume `that it'is desired to set the semaphore to its danger-indicating position. The operator at the signal-tower closes the switch S in the operating-circuit, thus energizing the motor 17 causing its plunger 17 to be drawn up and carry with it the bar 13. As the bar 1.3 13 starts on its upward movement the pin 14 will engage the arm 1.0 of the pawl 10 and release it from engagement with ,the ratchet 5.. As soon as the awl 10 is released from engagement with t e ratchet 5 the bar 13 continuing its upward movement .has its hook ortion 13 brought into engagement with t ie pin 6 of the disks 6 6 and turns the shaft 1 in the direction of the arrow. Just after the pin 14 has released the pawl 1() it passes out of engagement with the arm 10 ofthe pawl 10 and allows the pawl 1() to again drop into engagement with the periphery of the ratchet 5, so as to stop the rotation of the shaft in the direction of the arrow when it isV moved through one-fourth revolution. When this position is reached, the blade 43. is horizontal, while the blade 43 is vertical, thus show-mg the red blade or danger-signal.

Ati 3o 47 and the lamp movement. the signal to merely closes the switch S, as-before,

15 will engage the contacts 206L 20 and close the same time the arms 24a are moved through one-fourth revolution to bring the lenses 28a in alinement with the apertures 47 29 to show a red light and Indicate a dangersignal. As the bar 13 reaches the limit of its upward stroke the pin the return signal-circuit, thus indicating to the tower operator that the semaphore has been moved to its proper position. The operator then opens the switch S to denergize the motor 17, thus allowing the plunger 17lL and the bar 13 to drop by gravity to l i l i l l l i l l l its inital f position, the pi'n 14 passing over the beveled l portion of the arm 10a dropping into position, likewise passes ofthe pawl 10 and. Ywhile the hook 13u i over the next pin 6l and i drops into position. At the same time the l hook 13b of the bar- 13 drops over the stud 12, which holds the bar 13 in proper position to engage the pin 6a for performing the next When it is again desired to set l its safety position, the operator ,l when the l foregoing operation will again take place, with g theexception thatthe next signal set will be safety instead of dangen the preceding signal. Thus it will be seen that the shaft 1 rotates in one direction to alternately eX- pose danger and safety signals andalsoopj eratesfan indicating-signal at the tower op` i erators office whenever the semaphore has been operated.

In Fig. 7 I have shown a slightly-modified form of my invention in ywhich the signalshaft 100 is arranged vertically and passes through bearinglapertures 65X in a cross-bar 65, secured to. the standards 2 2 in lieu of the .i rod 18. 'Ihe 'motor 17 is preferably fulcrumed l on a rod 118, mounted in a bearing 2X in the litandard 2 and abearing 63X in the bracket .'58, which is bolted at 64 to the cross-bar 65. The shaft 100 has its lower end provided 'with a cone-bearing 54,which cooperates with the ball-bearing in the lower cross-bar 52, which is secured to the standards 2 2 by bolts i 61, as shown. The disks 3, 5, and 6 6,- together withvthe collar 4 in this form of my invention, are mounted on ashaft 105, which is l journaled in a bearing in the standard 2 and in a second bearing 43 in the' supplemental bracket-standard 53, which is secured to the cross-bar 52 and the standard 2 by the bolts'l -and the screw 62, as shown. The shaft 105 carries a bevel-pinion 58 of forty-live I degrees pitch, which meshes with a second bevel-pinion 57 on the shaft 100, so that the rotarymotion of the shaft 105 is imparted to the shaft'100, as will be clearly understood y reference to the drawings.

In the form of my invention shown in Fig.

7 the semaphoresignals are in the nature of disk signals, which are secured to the shaft 46 and which comprise `ing up the plunger 17 a red, respectively. Above the signal-disks 43a 43b the signal-lantern 120 is secured to the bracket 60, which bracket is-seeuredio the shaft 100 by a collar (i0, as shown, and the lamp in this ease lis inclosed within the usual lamp-casing 2W and is provided with four lensed apertures 128n 12dd and 128 12S, alternate ones of which are red, while the others are white to correspond with the disk signals 43a 43h to show safety or danger signals, as the case may be. In this form of j myinvention also the housing 46 is made with a conical top to form a watershed and a washer 68 is carried bythe shaft 100 to prevent ingress of water into the casing 46 through the top thereof. In other respects this form of my invention is constructed along the same lines as that shown in Figs. 1 to 8, inclusive, of thel drawings. The operation of the form of my invention shown in Fig. 7 is follows; The operator closes the switch S to energize the motor 17, thus drawand rotating the shaft 105 in the same manner as the shaft 1 in Figs. 1 to 8, inclusive, is rotated. The motion of the shaft 105 is imparted to the shaft 100, which isV turned through one-fourth revolution at each operation of the motor 17.` The signal-circuit is operated in the same manner as before explained for the invention shown in Figs. 1 to S, and as soon as the signal has been moved the switch S is again opened.

f From the foregoing it will be 'seen that .I have provided avery simple and effectivelyoperating semaphore-signal capable of use either as a track-signal or as a pole-signal, as the case may be. Furthermore, I have rovided a semaphore in which the signal-shaft is rotated* intermittently in 'one direction only, thus insuring a more perfect operation of the apparatus than is possible where the shafts are turned in one direction and then turned back again.

Attention is particularly called to the pawls 8 and 10, which automatically lock the semaphore, so that it cannot be turned in either direction by the wind or moved by any one tampering with the signal alone, but can be only moved by the operation of the motor 17 when the pawl 10 is released, and then only in a direction in which the shafts 1 or 100 are designed to move.

From the foregoi description, taken in connection with the accompanying drawings, it is thought that the complete construction, operation, and many advantages of my in- IOO' ITO
