SWITCH.
Application filed February This invention relates to switches and more particularly to tongue switches, and has for its object the provision of a novel means for holding down the point of the switch tongue.
Another object is to provide holding down mechanism which will be applicable to standard trailing point switches where the standard spring or lock mechanism is not required, and yet it is desirable to hold the tongue point to the bed of the switch to pre vent excessive wear and keep the tongue in the worn switch bed from excessive noise duc to it jumping about Aand in extreme cases from jumping out of place due to the force of traffic passing over it.
A further object is to provide a. switch having the novel design, construction and combination of parts hereinafter described in the following specification and illustrated in the accompanying drawings:
ln the drawings Figure 1 is a plan view of a portion of a standard tongue switch having my invention applied thereto.
Figure 2 is a sectional elevation on the line II-H of Figure 1.
Figure 3 is a view similar to Figure 1 showing a modified embodiment of my invention.
Figure 4 is a sectional elevation on the line lV-IV of Figure 3. 4
Referring more particularly to the drawings the numeral 2 designates the switch body, which is provided with a longitudinal groove or recess 3 forming a tongue bed, to receive the switch tongue 4.
The switch vtongue 4 is provided with a downwardly extending lug 5 at a point intermediate its ends, which lug is apertured at 6 in a direction transversely of the longitudinal axis of the tongue.
A standard spring box 7, such as is ordinarily used to house the spring operating r mechanism of a trailing switch, is secured by bolts S to the switch body 2 and the switch body 2 and box 7 are apertured to form a passage 9.
A casting 1() having spaced vertically extending ears 11 is secured in the box 7 by the bolts 8. A. crank lever 12 is pivotally mounted between the ears v11 by a pivot pin 14. The forward 'arm 15 of the crank lever is slotted longitudinally at 16 to receive a holding down bar or rod 17 The other or rear arm 18 of the crank level` is apertured.
1e, 1926. serm- No. 88,637.
at 19 to receive the downwardly bent rear end 2O of the bar or rod 17. The rear arm 1S of the crank lever is provided adjacent its rear end with a vthreaded aperture 21 in which is threaded an adjusting screw 22 adapted to be threaded through said aperture and bear against the casting to rock the crank lever about the pivot pin-14.
The rod or bar 17 has its forward end mounted in the aperture 6 of the lug 5 and said lug is adapted to move along said rod as the switch tongue is moved from side to side of the groove or bed 3 of the switch.. body 2.
A stiifener tube 24 is mounted on the rod 17 to stifi'en and strengthen it against bending strains.
In operation, after the parts are assembled the screw 22 is threaded througl'r the aperture 21 in the arm 18 of the crank lever thus forcing the arm of the crank lever downwardly against the rod 17 and in turn forcing the rod 17 downwardly against the lug 5 so as to hold the tongue 4 in its bed 3.
If it is desired to remove the rod 17 for any reason it is only necessary to remove the screw 22 and withdraw the rod into the box 7 and then tilt it upwardly until it clears .the box and then remove it, the passage 9 being of suicient size to permit this tilting of the rod 17.
In the modied construction of Figures 3 land 4 a telescoping holdingl down rod or bar 17a is provided for holding down the tongue. The rod 17a is composed of a solid bar portion 25 adapted to be slidably fitted within the aperture 6 in the lug 5, a tubular portion 26 welded to the bar portion 25 and extending through the passage 9, and a second bar portion 27 telescoped within the tubular portion 26v and removably held in position by a pin' 28 which extends downwardly through the tubular portion 26, the bar 27 and flange 29 of a casting 10 which is substituted for the casting 10 of the preferred embodiment of my invention.
The rear end of the bar portion'27 is enlarged to form a head 30 which is apertured -to receive a bolt 31, which bolt extends downwardly into a squared recess 32 in the casting 10a and is threaded in a nut 33 mounted in said recess. The nut 33 is slidably mounted in the recess 32 and held against rotation by the walls thereof. A coil spring 3 4 is mounted around the bolt 31 between the' head 30 of the bar and nut ecy 33 so that by threading the bolt 3i. through the nut 33 the spring will be compressed.
.i locking ring 35 is iitted over the head ot the bolt 3l and is provided with lugs 36 which engage the bar 27 to prevent rotation ot' the bolt 3l and ring.
The castingl0n extends upwardly along the sidewall oi the box 7 next to the switch body and is apertured at 38 to permitthe rod 17 to enter tie passage 9 .termed by the apertures in the bof: Y and the switch body The, tace ot' the casting above the aperture 3S is rounded to form a tulcrum bearing` tor the rod 17.
in operation, when the ports are assembled, the bo t "ll will be threaded downwardly through the nut 33 tous compress ing the spring 3l and 'forcing' the rod i7 against the iulcrum bearing` 39 and cause ing` the forward end oi the rod to apply a downward force against the lug 5 of the tongue Due to the spring 341 between the nut 33 and rod l?l the torce applied to the rod will be yieldable and, theretore, considerable torce may be applied to the rod 17 and tongue wit-hout bending the rod or binding the switch tongue lli/*hen it is desired to remove the rod 17 for repairs or renewal, the pin 2S is removed, the locking ringv 35 is removed, end the bolt 3l is then unt-hrea-oed .trom the nut so as to permit removal oi the bolt and spring` rlhe bar portion 27 is then telescoped within the tubular portion 2G, and the telescoped rod 17a is then moved rearwart ly within the bof; .7 and 'tilted upwardly so as to clear the bon.
`Vilhile l have shown and described eertain specitie embodiments of my invention it will be understood that l do not wish to be limited thereto, since various modifications may be made without departing from the scope ot my invention as dei'ined in the appended claims.
