WALTER ROWLANDS, OF MONTREAL, CANADA.

RAl LWAY-SWITCH STAND.

SPECLFICATION forming part of Letters Patent No. 534,761, dated February 26, 1895.

Application filed August 22, 1894, $erial No. 521,049. (No model.)

To all whom it may concern:

Be it known that I, WALTER RowLANDs, of

the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Railway-Switch Stands; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to switch stands, provided with automatic locking parts, and has for its object an improvement in the general construction of such stands, and particularly in the pedestal or base thereof, the target rod connection, the operating lever, and the looking parts of the locking bar. For full'comprehension however of the invention reference must be had to the annexed drawings forming a part of this specification, in which like symbols indicate corresponding parts, and wherein Figure 1 is a side elevation of the switch stand, adapted to be used for yard work, but capable of having added to it the post and other parts suitable for main line w'ork, portions of such additional parts being indicated by dotted lines. Fig. 2 is a View of the stand similar to Fig. 1, but with switch unlocked. Fig. 3 is a front elevation of the switch stand with parts locked. Fig. 4 is a horizontal section of stand on line a: a: Fig. 3. Fig. 5 is a plan view of the table portion and base of the stand, and Fig. 6 a detail view partly broken away of the lower portion of the stand and the locking parts of the locking bar.

A is a metal pedestal or base, hollow as formerly and provided with the usual bottom flange A, flat top or table portion A lateral projection A and in this case formed with a vertical recess A in its rear side to receive the necessary post 1) indicated by dotted lines in Figs. 1 and 4 when the stand is used for main line work, the post being preferably secured in place by bolt b passing through it and the pedestal.

The laterally projecting portion of the table A is perforated as usual for the vertical looking spindle 0 upon the upper end of which is keyed the lift casting or head piece D. This lift casting has an upwardly projecting socket or holder section D, formed with a square vertical recess or socket D to receive the squared ends of either a long target rod, used proper light or side of the targetcorrespond ing with the position of the switch. The usual set screw D is of course used to prevent accidental vertical displacement of the target rod.

The operating lever or handle 0* is preferably made hollow with lifting cam head e pivoted as usual to the lift casting and in this case formed with adownwardly projecting lip or shoulder O on its under side in such a position that as the handle is turned down the inclined side 0 of such lip will bear beneath the lower edge of the table portionA of the base and thus serve to force downward the lift casting and with it the locking spindle O and the locking bar F, to be presently de-' scribed, so that any obstruction in the form of dirt, &c., thatmight be in the way of the downward movement of the locking bar will be overcome.

To further prevent any possibility of an accumulation of dirt interfering with the downward movement of the locking bar as is the case when such bar is formed with a downward projection to enter notches in the lock plate G in advance of the stand, I form an upward projection G on such plate and two openings F in the bar, either of which is adapted to receive the projection as the bar is forced downward.

As a ready means of effecting an operative connection between the locking bar and the vertically movable locking spindle, I extend as at N the outer end of the crank N on the lower end of such spindle so that the inner end of the locking bar instead of requiring to be curved upward and connected with the spindle above the lock casting K can remain straight and be located between the upper surface of such extension and the under side of the lock casting K.

Reverting to the operating lever I may say that it has been found desirable to determine the precise distance of its throw to one side or the other in shifting the rails of the switch, and I accordingly form limiting stops Z Z, on the upper surface of the table A into contact with which it is thrown, and in order that the lift casting D which is wider than the lever, may not engage the stops and so prevent the lever being thrown the full distance, its under side is cut away as at D to avoid contact with them.

What I claim is as follows:

1. Aswitch stand havingits pedestalformed with a vertical recess in its side for the purpose set forth.

2. In a switch stand, the combination with WALTER ROVVLANDS.

In presence of WILL P. McFEAT, FRED. J. SEARS.
