I-BEAM-TRACK-SWITCHING- DEVICE.

Specification of Letters Patent.

Patented Jan. 9,1912.

Application filed February 11, 1909. SerialNo. 477,409.

To all whom it may concern:

Be it known that I, CHARLES MESSIOK, a citizen of .the United States, residing in Hackensack, county of Bergen, State of New Jersey, have invented a new and useful Improvement in I-BeaIn-Track-Switching Devices, of which the following is a description.

My invention relates to I-beam track switching devices, such as are used in connection with trolley hoist I-beam tracks, etc., and more particularly to the construction ,of the various parts in a strong and substantial, yet inexpensive manner, of wide applicability, and easy of erection.

Referring to the accompanying'drawings in which typical devices are shown, and in which similar characters of reference in dicate the same parts in the several figures; Figure 1 is a top view of an I-beam track switch, attached to a main track at the swivel end and connecting two branch tracks at the head end. Fig. 2 is an enlarged side view of the swivel end of Fig. 1 partially broken away to show the swivel disk. Fig. 3 is an enlarged end view of the head end, shown in Fig. 1, looking from the swivel toward the head. Fig. 4 is an enlarged sideview'of the head end shown in Fig. 1.

Fig.5 is an enlarged partial end view of the head end looking from the line 55 in Fig. 4 in the direction of the arrow. Fig. 6 is a partial perspective view of the switch tongue and the branch tracks with a trolley hoist mounted on one of them. Fig. 7 is a view of the bumper devices applied to a transfer table with a bumper for both the transfer table track and for the branch track.

1 is the end of a stationary track.

2 is the end of a branch track.

3 is the end of a second branch track.

4 is a partially radial angle iron track connecting branch tracks 2 and 3 having one leg fastened to the branch tracks by bolts 6, the vertical leg toward the swivel. The angle iron track 4 has straight extensions carrying pulleys 7 and 8; it also has fastened to it short vertical pieces of angle iron 9 and 10 to limit the movement of the switch tongue head.

11 is a switch tongue having a broad swivel plate 12, bolt-ed to its swivel end by bolts 53. The plate 12 carries a swivel pin in the form of a disk 13 riveted to it by rivets 14. .The rivets 14 are counter-sunk into the plate 12. Ahead casting l5v is bolted to the end'of the tongue 11 by bolts 16. r The casting 15 has extensions 17 and 18 adapted to rest on the ends of either of the branch tracks 2 and 3. The extensions 17 and 18 have centering lugs 19 and 20, beveled at their inner faces at an abrupt angle, in order to clutch the branch tracks and form a lock to keep the head casting. l5 centeredtherewith against side thrusts. The lugs 19 and 20 are beveled at a gradual angle on their outer sides in order to permit them to be easily drawn up onto a branch track. The casting 15 has a hole bored therein, in which is journaled a shaft 21. The shaft 21 is held in position against end movement by the collar 22, secured thereto by the taper pin 23 and is held a ainst end movement at the opposite end by t e casting 24, through which it passes and at which it terminates, being held therein by the taper pin 25. The-casting 24 extends upward to receive a second shaft 26 parallelto shaft 21. Shaft 26 is secured in casting 24 by taper pin 27. Casting 24 extends farther upward in a portion 28 of reduced dimensions and has a hole 29 near the top.. I

On shaft 26 is revolubly mounted a 'wheel 30 held from end movement by the casting 24 and the collar 31 which is fas-. tened to shaft 26 by thetaper pin 32. The shaft 26 extends V in reduced diameter through the roller 33 which is revolubly mounted thereon and is held in position by I the washer 34 which is riveted on the end of shaft 26. Washer 34 is best shown in dotted lines in Fig. 4 as is also the reduced portion of shaft 26.

In the flanges of the branch tracks 2 and 3 are out oblong holes 35 close to the Web and vertically in line. Flat bumper-bars 36 are fastened at their upper ends to devices 37, which I designate as butterflies, in or.- der to conveniently identify them. A butterfly is a casting with a rearward extension 38 for attachment to a flat-bar 36 and a flat body portion 39 at right angles to the extension 38. At the forward upper portion of body 39, there is a short horizontal plane '40, (shown best in dotted lines in Fig. 3) which extends into upwardly inclined planes '41, a short distance each side of the center.

At the lower portion of body 39 is a second horizontal plane 42, (shown best in dotted lines in Fig. 3) a little longer than plane 40 and extending into upwardly inclined planes 43. The body portion 39 and the planes 41 and 43 are co-extendant on either side of the center of the butterfly. The bumperbars 36 are attached tothe butterflies and dropped into the holes 35, having free vertical movement therein.

With the parts as above described, I place the complete switch with the swivel plate 12 resting on the stationary track 1 and the wheel 30 resting in the center of the radial portion of angle iron track 4. I place filler. plate 44 on track 1. I place retaining plate 45 on top of filler plate 44 with the swivel hole 46 over swivel disk 13, and bolt both plates'44 and 45 totrack 1 by bolts 47. Plates l2 and 45 are broad and, therefore, form a hinge between the track 1 and the switch tongue 11, free to swing laterally, but adapted to resist any twisting which may tend to occur between the switch tongue 11 and the track 1 .from the operation of trolleys over the switch. I fasten a rope 48 in hole 29 and pass it over pulley 7 allowing the end of the rope to hang pendant therefrom. I fasten a second rope 49 to the opposite side of hole 29, pass it over pulley 8 and allow the end of the rope to hang pend- 7 ant. therefrom. I now pull on the pendant end of rope 48 which draws the head end of the switch toward branch track 2 with the wheel 30, rolling on radial angle iron track 4. As the head approaches track 2 the roller 33 enters between the upper and lower planes of the butterfly on track 2, andautomatically starts to lift it and the bumper-bar to the indicated inoperative position (in Fig. 6). with the roller 33, supporting horizontal plane 40 of the butter- 3 fly. As I pull the head toward track 2 the I into a. centered position on track 2 with the I able to heavy work as iron or steel castings external angular surface of a lug 20 strikes the upper edge of the flange on track 2, and rides up over it until the extension 1.8, after it has been pulled across the top of track 2, strikes the angle iron stop 9, which prevents the headfrom passing beyond -the center of 1W1l3h the conditions to be met in all classes of I-beam switching.

track 2. I now release the pull on the rope 48 which allows the switch to fall by gravity internal abrupt angular portions of the lugs 19 and 20, hugging the upper flange of track 2 and positively centering the switch thereon. The head of the switch now rests its weight on the extensions 17 and 18. The

switch may be now pulled to track 3 by pulling on rope 49 which first pulls over the top end ofcasting 24 toward track 3 which revolves shaft 21 which acts as a center, andin conjunction with shaft 26 and wheel 30 has i a lever action first. lifting the head and free-.

ing the lugs 19 and 20 from their centering effect on track 2, then dragging the switch to track 3 and successively causing the bumper to automatically become operative on track 2 and inoperative on track"3, by the successive lowering and raising in tracks 2 and 3 of their respective butterflies by the roller 33. -The planes 43 are normally inoperative but in the event of a bumperbar sticking and not falling by gravity, as

the roller 33 is drawn away froma butterfly to another'branchtrack, the roller will strike the said planes 43 and prevent further movement of the switch head until the bumper-bar. has been forced down into opera-' tive position..,The plane 42 is merelyto strengthen the structure of the butterfly and upon occasion, may be dispensed with.

The trolley 50 has a yoke 51 against which i the bumper-bars 36 strike.

' In Fig. 7 I show butterfly operated bumper devices in a branch track associated with a transfer table crane bridge track also operating a bumper in the bridge track."

100 is a butterfly which is mounted on a bumper-bar 101 in the branch track 102. Roller 103 is mounted on a lever bar 104 which is swiveled 011 the head casting 105, by a bolt 110. Head casting 105 is fastened to the bridge. track 106. The lever 104 at the opposite end from roller 103 is loosely fastened to bumper-bar 107 by bolt 111.

. As bridge track 106 is run to a centered position with branch track 102, the roller 103 lifts butterfly 100 and bumper-bar 101," until its stop 108 strikes the bottom of the upper flange .of branch .track 102, which prevents the bumper-bar 101 from being further lifted; but as the roller has not yet reached the lowest part of the butterfly planes, the lever' 104 operates, and lifts bumpenbar 107 by tilting downward the roller end of the lever-bar 104 into the ins dicated po'sitionQ Bu1nper-bar107 is also provided with a stop 109. bars thus become, automatically inoperative Both bumper when the tracks are centered. The stops 108 and 109 also act to force the liftingfto an approximately even height of both the: I i

v bumper-bars, when the device operates.

.I may vary these devices in accordance This construction is particularly adaptor forgings of comparatively small size may be used while most of the structure is of structural steel, cold rolled shafting and other standard material.

Particular attention is called to the easy and inexpensive work in connection with building and erecting these switch devices.

Attention is also called to the locking lugs than the fish-plates used to join the various rails in a straight track. The trolley wheels run freely on the outer edges of the lower flanges of the I-beam without interfering with the bumper-bars. This type of bumper-bar also places a bumper where it will lave the least harmful effect in operation.

7 Bumpers which strike the wheels of the trolley, tend to bend the trolley wheel shafts. The construction is such that when the track and tongue are not exactly centered and locked, the tongue will be at a higher level which acts as a visible danger signal to the operator.
