SWITCH-STAND.,

SPECIFICATION forming part of Letters Patent No. 368,169, dated August 9, 1887.

(No inadcl.)

To all whom it may concern:

Be it known that I, EUGENE J. REMILLON, of Moberly, in the county of Randolph and State `of Missouri, haveinvented a certain new and useful Iniprovement in SwitchStands, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification, and in which-` Figure l is a side elevation of my improved stand with part of the housing removed. Fig. 2 is a similar view looking at another side of the stand. Fig. 3 is a vertical section taken on line 3 3, Fig. 1. Fig. 4 is atop view. Fig. 5 is a top view showing the leverin different position from Fig. et. Fig. 6 is a bottom view. Fig. I is a bot-tom view showing the shaft, crank,or arm in a different position from that shown inA Fig. (3. Figs. 8 and 9 are detail elevations, part in section, showing different positions of the` crank. Fig. 10 is a top view of the housing. Figs. Il and 12 are detail views illustrating the manner of holding the sleeve that surrounds theswitch-shaft from turning. Fig. 13 is a detail view illustrating` my invention applied to a switch, where one way the switch is positively locked. y

My invention relates to a switch-stand that will hold the switch-points in either position placed, and at the same time will permit the points to be forced over automatically by a train running with the points in case the switch should have been left closed, the device at the same time not interfering with the movement of the switch by hand.

This invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the housing or frame, supportgd on a suitable base, B.

C represents the vertical rockshaft,to which is rigidly secured a collar, D, above the housing, and to the collar is pivoted at ,E the operatinglever E, having a slot or opening, E, to receive a lug or projection, I, on a cap, I, that rests on the top of the housing A. Vhen the lever is lowered, the projection I' eutersthe slot E2 to hold the switch closed. On the lower end of the shaft C is a crank, G, to which the switch (not shown) is connected by a rod, C.

Surrounding the shaft is a sleeve, F, enlarged at its upper end, as shown at F, to receive a spring, (1, that surrounds the shaft beneath the top of thehousing. (Sec Fig. 3.) The lower end of the sleeve has abasc, F2, with a depending V-shaped cam, F, against which bears a friction-roller, C, On the crank O', the roller, when the switch is in either position,notreach ing quite to the base of the cam, as shown in 6@ Figs. S and 9, so that there will always be a tendency for the cam to hold the switch-points up tight against the main rails, owing t0 the downward pressure of the spring G on the sleeve F, the points ofthe switch-rails bearing 55 against the main rails acting to hold the roller Oii from reaching the base ofthe cam on either side.

rlhe base F2 of the sleeve has a semicircular projection, F, extendiugdown ward therefrom outside of the cam F, and the edges of this projection bear against a ledge, A, of the housing, as shown in Figs. S, t), and l2,and acts to keep the sleeve from turning, but does not interfere with its vertical movement. rlhe sleeve is held from turning at top by a ledge, A, on the housing, against which bears a projection, F", on the sleeve. (See Fig. 11.)

The lever E is provided with a cam, E, that bears against the loose cap I of the housing. so W'hen the lever is thrown up into the position shown in Fig. 3,itallows the shaft() to descend until the roller C is beneath the point ofthe cam F, (see Fig. and dotted lines,Fi0. 9,) so that the switch can be moved either way by S5 hand and not be interfered with by the roller coming against the cam. Now,wheu the lever is lowered into the position shown in Figs. l and 2, the shaft is raised again and the pressure of the cam on the roller will hold the 9o switch in whichever position it may be placed; but should the switch be left closed against a main rail anda train approaches from behind or not facing the points,the wheels in wedging between the main rail and the point againstit will force the switch-points over, the shaft C being permitted to turn by the upward 1noVement of the sleeve F against the pressure of the spring G,whieh is caused by the roller O bearing against the cam F3. The train is thus loo allowed to pass through without damage to it or the switch and without danger to the pas- 2' l i i 368,169

sengers. The upward movement of the sleeve is indicated .by dotted lines in Fig. 1.

, In Fig. 13 one-half of the cam only is shown, which is the construction used for a switch where it is desirable to have only` one way crank, substantially as shown and described,

for the purpose set forth.

2. In a switch-stand, the combination of the housing, vertical shaft, earn-lever pivoted to the vertical shaft, crank on the lower end ofi the shaft, friction-roller'on the crank, sleeve;

surrounding the shaft,having abase provided with a downward'projection, F, and cam F3, and spring G, located between the upper end of the sleeveand the top of the housing, substantially as set forth.

3. In a switch-stand, the combination of the housing having the ledges A? A3,vertical shaft, cam-lever pivoted to the shaft, crank on the lower end of the shaft, sleeve surrounding the shaft, spring located between the'top of the housing and the sleeve, projections F* F5 on the sleeve, and cam F, substantially as set forth. l

4. In as-witch stand, the combination of the housing, vertical shaft, slotted lever, collar on the shaft which is provided with a projection to which the lever is pivoted, cap on the housing,-ears I2 on the cap engaging the projection on said collar, and projection I on the cap 'for entering the slot in the lever, substantially as and for the purpose set forth.
