SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 623,516, dated April 25, 1899.

Application filed February 27, 1899. Serial No. 707,008. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. CAIN, a citizen of the United States, and a resident of Vaupacadn the county of Waupaca and State of \Visconsin, have invented certain new and nsefulImprovemen ts in Switch-Stands; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide simple, economical, and automatic-locking switch-stands, as well as to insure proper working of corresponding targets and distant signals operative in conjunction with said targets.

Therefore said invention consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a partlysectional view of a switch-stand in accordance with my invention, the plane of the View being indicated by line 1 1 in the third figure of the series; Fig. 2, a similar view of a portion of the switch-stand on the plane indicated by line 2 2 in the succeeding figure; Figs. 8 and 4, plan views, partly in horizontal section, on the planes respectively indicated by lines 3 3 and 4 4 in the first figure; and Figs. 5, 6, and 7, detail horizontal sectional views on the plane indicated by line 5 7.

in said first figure, these latter views serving to illustrate the throw of the switch-lever and relative movement of a target-shank,

3 5 said lever being illustrated by a dotted line.

Referring by letter to the drawings, A indicates the base, B the standards, and C the head, of my improved switch-stand, this head being provided with a circumferential slot b, intercepted by a vertical notch c for the switch-lever, hereinafter more particularly specified. Stepped in the base and extended up through the head aforesaid is a shaft D,

and, as herein shown, a sheave E may be made fast on the lower portion of the shaft for connection with the cable of a distant signal.

Loose on the shaft D is a sleeve F, and engaging trunnions d, extending from the lower portion of the sleeve, is the spanner end of one arm G of a bell-crank lever in pivotal connection with ears e,that extend inward from one of the standards B, one of these ears being shown in Fig. 1. The forked lower end of the arm G of said bell-crank is pinned to a link II, that is joined at its outer end to the head-rod I of the switch, the inner portion of said link being movable between base-ears f, provided with apertures, with which a corresponding aperture in the aforesaid link is registrable when the switch is closed to be engaged by a curved bolt J, that is herein shown as part of a fixture on the under side of sheave E, but which may have direct connection with shaft D in the absence of said sheave.

Between fixed upper collars g of the sleeve F is a loose collar K, and in connection with diametrically opposite lugs of this loose col' lar are the lower ends of a pair of links L, having curved slots h, engaged by studs 1', extending from the shaft D aforesaid. The upper ends of the links L are in pivotal connection with the inner spanner end of the hand or switch lever M, and this end of said lever is likewise connected to an enlargement j of shaft D in the plane of the circumferential slot of the head 0 above specified.

Within the head C, above the enlargement j of shaft D, is a horizontal plate N, through which said shaft passes, and the shaft-aperture in the plate is enlarged to form a quad- 8o rantal space 76. (Best shown in Figs. 5, 6, and 7.) The upper end of shaft 'D is provided with a vertical socket for the shank O of a target P, and a lug m extends from this shank through a quarter-circle slot in the socket portion of said shaft into the quadrantal space of the plate N aforesaid.

When the switch is open, the switch-lever M is dropped in the vertical notch cbetween the standards B, as shown in Fig. 2, and thus said switch is locked in open position, the target P being displayed at a right angle to the adjacent railway-track.

To close the switch, lever M is raised from the position shown in Fig. 2 to that shown in 9 5 Fig. 1, whereby the sleeve F is lifted and the bell-crank in connection therewith operated to throw the switch; but the position of target P is not altered until said lever is moved slot in the head C of the stand.

The relative arrangement of the quarterone-quarter of a circle in the circumferential roo circle slot in the upper socket portion of the shaft D and the quadrantal space in headplate N is such that when lever M is brought to horizontal position out of the vertical locking-notch of the stand it must be moved onequarter of a circle in the circumferential slot of the stand-head before said shaft will have opportunity to operate upon the lug m of the target-shank O, as is clearly illustrated in Figs. 5 and 6, and, as shown in Fig. 7, it requires a further quarter-circle movement on the part of said lever to swing the target P in position to show that the switch is closed, the length of the aforesaid slot being such that the throw of the aforesaid lever is limited to one-half of a circle. The movement of shaft D will actuate the sheave F to shift a distant signal with which it may be in cable connection, and as the rod D finishes its halfcircle movement the bolt J is engaged with the base-earsf and interposed link II to lock the switch in closed position.

Upon a reverse operation of the switch-lever the bolt J is retracted, the distant signal returned to its former position, and the target moved to show that the switch has been moved to open position, said lever being depressed to stand as shown in Fig. 2.

In matters of detail it is possible to vary the structure herein shown and described without departure from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
