SWITCH-STAND Specification of Letters Patent.
Patented Dec. 10,1907.
0 Application filed March 19.1907; Serial lio. 363.311.
To all whom it may concern:
Be it known that we, WILLIAM W. ALLEN and JOHN METzeER, citizens of the. United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Switch-Stands, of which the following is 'a specification.
Our invention relates to means for adjusting the throw of an ordinary rai way switch by adjusting the throw of the crank.
The features of the invention are more fully set forth in thedescription of the accompanying drawings, forming a part of this specification, in which Figure 1 is-a side elevation, partly in section, of a switch-stand. Fig. 2 is a central vertical section of the base of the stand shown-in F g. 1, with the modification of the location of the adjusting eccentric. Fig. 3 shows the relation of the connectingrods with the adjusting eccentric, and provided with an adjustable clevis at the opposite end taken on line ac, Fig. 1
1 represents the feet of an ordinary high switch-stand. 2 represents the arch between the feet. 3 represents the upright column of the stand. 4 represents the crank shaft. 5 represents the switch lever. 6
represents the target-rod. 7, 8, represent,
gears for moving the target-rodj 9 represents the notch into which the switch lever dro s. 10 represents a lug engaging a slot in tie switch lever for applying a pad lock to lock the lever in position. These parts are of the ordinary construction. The preferred form of (onstruction and arrangement of these devices for adjusting the throw of the crank is shown in Fig. 1, in which:11 represents an ordinary crank pin. 12 represents mounted on the crank pin 11 and provided with a flange. 13 represents notches formed in the peri hery of said flange. 14 represents a pin firmly fixed in the crank, d epending ano engaging one of the series of notches in the eccentric sleeve. 15 represents the connel ting rod. 16 represents a clevis thereon. 17 represents a clevis bolt which engages with an orifice in the switch bar which ties the two switch rails together. 15 represents the end of the connecting rod engaglng over the eccentric sleeve 12, the connecting rod ournaling on said eccentric sleeve.
stand.
an eccentric sleeve When it is desired to increase or diminish the throw of the crank rod and the distance the switch rails are moved, the nut 1. 9 on the end of the crank-is removed This allows the connecting rod and eccentric to drop down so asto free the eccentric notch from contact with the keeper pin 14. The eccenconnecting red, as maybe desired.
In Fig. 2, I have shown a modification of the mode of connecting the eccentric'to the crank shaft. The eccentric sleeve 12 journals in the brace plate 23 of the switch- 24 represents a collar on the crank shaft carrying the keeper pin 14 to engage in one of the notches of the eccentric sleeve 12. In this case, the connecting rod between the crank pin and switch-bar journals directly on the crank pin.
When it is desired to adjust the eccentric to a new position the pin 25 is driven out so that the collar 24 which holds the keeper pin may be lifted up to free its engagement with the eccentric. The eccentric may be then turned to bring any desired notch within the ath of the keeper pin when the collar is owered and pinned in position.
7 By the means herein shown and described, we are enabled to accurately adjust the throw of the switch bar, so as to insure a proper contact of the split switch rail to the fixed rails of theswitch.
Having described our claim 1. In a switch-stand, a crank shaft and invention, we
.connecting'rod, andan adjustable bushing adapted to be set to adjust the throw of the crank, substantially as described.
2. In a switch stand, a crank shaft, an eccentric sleeve mounted on said crank shaft, means. for adjustably securing said eccentric sleeve to said crank shaft and a connecting rod journaled upon said sleeve, substantially as described.
3. In combination with a crank shaft of a switch-stand, an eccentric, notches inthe periphery of the eccentric, a keeper pin carried by the crank shaft and projecting in the path of the eccentric notches, and means for releasing the engagement of the keeper pin to allow the rotary adjustment of the eccentric,
. periphery of the eccentric, a keeper pin carried by the crank shaft and projecting in the path of the eccentirc notches, and a connect ng rod j ournaled upon the eccentric hub, substantially as described.
5. In a switch-stand provided with a notched'eccentric, a keeper pin engaging a notch in the eccentric, a connecting rod journaled upon the crank pin at one end and provided with a clevis threadedly engaged 15 with the connecting rod, and a removable clevis pin forming a swiveled connection of the connecting rod with the switch-bar to which the swltch-rails are connected; substantially as described.
In testimony whereof, We have hereunto set our hands.
WILLIAM .W. ALLEN. JOHN METZGER.
