SWITCH-ACTUATING MECHANISNI FOR RAILWAYS.l

SPECIFICATION forming part of Letters* Patent No. 601,858, dated April 5, i898.

Applicata@ ined Augta 27, 1897.

for Railways; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tol make and use the same, reference 'being had to the accompanying drawings, which'form a part of this specification.

My invention has for its object novel switchactuating mechanism for actuating switches of street and other railways; and it consists of the construction, combination, and varrangement of devices hereinafter specied and claimed, and illustratedv in the accompanying drawings, in which` Figure 1 is a plan' view illustrating my invention with a portion of the case or cover removed. Fig. 2 is a side elevation with portions of the cases removed. Fig. 3 is an inverted plan View of certain features. Fig. 4 is an enlarged 'plan view of'themechanism adjacent to the switch-point, showing the lever B' in the different positions which it assumes.

My invention is designed to provide switchactuating mechanism for railways, of superior efficiency and utility, not liable to get out of order, and which may be readily and conveniently actuated at the will of the motorman ordriver of the car, as may be required. The desirability of a device of this sort which shall not be liable to get out of order, but which shall at all times be reliable, always eifective, and ready and convenient of operation iswell understood.

I carry out my invention as follows:

A represents the railway-rail, and A' a horizontally-reciprocatory switch-point of ordinary construction and arrangement. To actuate said switch-point@ connect therewith, as by a connecting-link B, a movableorvoscillatory lever B', which may have any suitable support O. To actuate the lever B', I provide a reciprocatory slide 1D, which may slide in suitable ways D', supported in any suitable manner. 1 The ways D' and the support O for 'serai No. 649,699. (No man.)

the lever B' may conveniently engaged with the inclosing case E. The ways may' engagement of the slide in place and its removal from the ways, if required. The slide is also preferably provided with a longitudinal recess (indicated at h) at its forward end to permit the slide reciprocating past the fulcrum Z9' of the lever B'andbymeans of which also the slide is further guided in its movements. Connected with the slide is a movable dog F, preferably fulcrumed to the slide, as indicated at f, so that it may oscillate laterally. This dog is constructed with two arms f' and f2, preferably forming recesses f3 and f4 on either side of the longitudinalcenter of the dog to engage the corresponding shoulders or spurs b2 and b3 upon the lever B', said shoulders being located on opposite sides of the longitudinal center of said lever or on opposite sides of the line drawn through the fulcrum-point longitudinally of said slide. The ways D on either side of the slide are prefer- ONE-HALF ably beveled inward at their ends adjacent to the dog, the dog being so yfulcrumed that it may oscillate laterally when drawn forward toward the lever B', the adjacent extremities of the ways, however, guiding the dog back into normal position whenever the dog is retracted. The dog, together `with the slide, may be drawn forward by areciprocatory rod G, which maybe carried anydesired distance from the switch-point along the adjacent rail. Thel slide may be retracted in any suitable manner, Vas by means of aspring H.

It will be obvious that whenever the outer end of the switch-point is thrown laterally to open or close the switch the leverB will have a corresponding location, said lever being either carried to the left or right with the movement of the switch-point in a corresponding direction, thereby carrying its shoulders h2 b3 to one side or the other of a line parallel with the slide centrally. through either of said recesses in the dog when the dog is in normal position. The shoulders b2 b3 in the lever are so located and arranged that when the switch-point is open one of the recessed arms of the dog will engage one-of said shoulders when the slide is drawn toward ICO the lever, and when the switch-point is thrown recessed arms of the dog will engage the other of said shoulders on the lever B', one

`recessed shoulder of the dog only being engageable on the movement of the slide with one of the shoulders of the lever B', which recessed arm, however, shall engage with the corresponding shoulder of the leverB, be-

ing entirely dependent upon the location of said lever, the location of the lever conforming to the location of the switch-point.

It will be seen that whatever may be the lo' cation of the switch-point the operationof the slide with the dog engaging a corresponding shoulder of the lever B' will move the switch into the opposite direction. Thus if the switch be open a movement 0f the slide with its dog engaging the lever will close the switch. It the switch be closed, the movement of the slide with its dog will open the switch. A movement of the slide bythe bar G always actuates the switch-point to throw said bar into the contrary position from that occupied when the slide is actuated. I would have it understood that I do notlimit myself solely to this particular form and shape of the dog; but this is a convenient form of construction for engaging the shoulders upon the lever B. If the lever B' be thrown to the left and remains temporarily in that position, obviously the next movement of the slide with its dog will so engage one of the shoulders of said lever as to throw the lever corresponding position.

the-car. v

Themechanism to actuatethe operatingrod -Gherewith shown and described consists of a lever I, fulcrumed at one extremity, as

indicated at t', said lever being provided intermedlate its ends with a shoulder I', proj ectingUpWarCLpreferably through a portion of the krail and into a groove of the rail, as

shown, so that the flange of the car-wheel K projecting normally upward adjacent to the inner edge of the rail, but normally out of the way. The lever J is formed with a shoulder j', bearing upon the lower end of the lever K, whereby when the lever I bears downward upon the outer end of the lever J its shoulder j', bearing against the lower end of the lever K, will tilt the lever K and throw its upper end' forward and above the upper surface of the rail adjacent thereto, so that the lever K may readily be engaged by any suitable operating device carried by the car.

My invention contemplates having the car provided with any suitable device to be depressed by the motorman or driver when he wishes to throw the switch. For example, t-he car may be provided with a bell-crank lever L, pivoted, as at Z, to a bracket or arm L', one end of the bell-crank being provided with a push-bar L2,extending upward through the platform of the oar adjacent to the motorman or driver, so that he `may readily, by pressure upon said rod .with his foot, actuate said bell-crank. Upon the truck of the car is also fulcrumed a lever M, connected with t-he bell-crank by a rod `M',whereby when the bell-crank is actuated the lever M will be thrown down to engage the 'lever K, which has been moved up into position to be engaged by the lever M. The lever M may he retracted in any suitable manner, as bya retracting-spring Vhen the lever M has been thrown down, so as to contact with the upper end of the lever K, the movement of the car will force the leverK forward, pulling the rod G in a corresponding direction until the upper end of the lever K has been forced over sufiiciently for the lever M to ride over and past the lever K. This movement of the lever K-will obviously, by means of a connecting-rod G, actuate the slide D and `said dog,wherebythe dog, engagingwith the lever B', as above specified, will throw the switch into a contraryposition'from that occupied when the driver -or motorman'threw down the lever M, carried by the car. The levers I, J, and K may be `provided with an inclosing case N. 'Itis obvious that all parts of the mechanism are readily accessible in case it may be required to renew or repair the same-as, for instance, should the spring It will be observable also that `the mechanism'hereinbefore described in no manner prevents the operation of the `switch-point by hand should it be desired or required, inasmuch as the switch-point maybe as easily actuated independent of said mechanism as in ordinary switch-bars. The rod G may be carried such a distance that amotorman or driver can readily see whether the switch has been thrown ornot.

The device is obviously very simple, economical, and durable.

Should the switch-point be located in connection with the rail adjacent to the mechanism shown in Figs. 2 and 4, of course a short connecting-link B will`be required, extending in the corresponding direction from thelever B'. Should the switch-point, however, 'be located on the opposite side of the track, the

connecting-lever B would be led in a corresponding direction from the lev'er B', as indicated in dotted lines in Fig. 2.

The inclosed case E may set snugly up against the adjacent rail, the cover portion fitting up against thef rail, so that dirt and snow will be eectually excluded, while a suitable drainage-pipe (indicated at E') will prevent the accumulation of water within the case.

It will be obvious that when the switch-point is located midway between its open and closed positions, as when an impediment might get between the point and the adjacent portion of the rail, the reciprocatory dog will ride between the depending shoulders of the lever without actuating the lever at all, the dog simply riding under the lever between said shoulders. lt isv obvious that the fulcrum of the lever is fixed and that. the opposite end ofv the lever swings in the arc of a circle, While the dog is both reciprocatory and laterally oscillatory. The guides or ways D' are fixed and Agive positive direction to the dog on its return into normal position.
