SPECIFICATION forming part of Letters Patent No. 491,463, dated February '7, 1893.V

Application -iiled February 8, 1892. Serial No. 420.695' (N0 mOBl-l To all whom t may concern,.-

Be it known that I, FRANK A. BEEMAN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Mechanism for Operating Railway Switches and Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in switch stands wherein the mechanism is adapted to be automatically operated by a passing car, locomotive or train, and designed to be replaced by hand after the passage of the train, locomotive or car, and more especially to mechanism that is equally applicable to stub and split-switches and adapted to simultaneously operate the switch and switchsignal.

My invention also relates -to certain features of construction and in combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure l is a view in perspective of my improved mechanism,portions being broken away or removed to reduce the size of the drawing and more 3o clearly show the construction. Fig. 2 is a plan of my improved mechanism secured to a pair of railway-ties with the signal and the upper portion of the signal-shaft removed and showing in solid and dotted lines, respectively, reverse positions of the mechanism. Figs. 3, 4f, 5, 6, and 7 are views in detail, Figs. 3 and 4 being in perspective, and Figs. 5 6 and 7 elevations partly in section.

A represents a metallic casing that, for the 4o sake of economy, comprises preferably a castiron box circular in plan and horizontal section, and out away and open on the side adjacent the track, as at A.

Casing A is preferably adapted to fit between a pair of ties and at the upper end has laterally-projecting flanges, a, located preferably diametrically opposite and being notched or slotted at the edges, as at a', for receiving spikes for securing the casing to the ties.

Casing A, at the upper end, has also a later- 5o ally-projecting flange, as at a2, located preferably midway between and at right angles to ianges a, that is, parallel with the ties and at right angles to the track. Flange a2 is grooved, as at a3, to afford bearing for a shaft, B, the latter being enlarged at either end of its bearing, as at b. Shaft B, at its outer end, has loosely mounted thereon a hand-lever, C, suitable means, however, being provided for preventing the hand-lever from moving end- 6o wise of and off the shaft, for instance, by the provision of a nut, D, mounted on the screwthreaded outer end of the shaft, with a washer, d, interposed between the nut and lever.

The inner and enlarged end of shaft B, that is locatedinside of casing, A, is provided with a laterally-projecting arm B', that, as shown, terminates in a cam, B2, the latter' being preferably circular and dish-shapedor concave as shown, and rounded at the edges, asV at B3, 7o the cam projecting endwise as well as laterally of shaft B.

Integral with, or rigidly secured to, the bottom of casing A is a block, E. Block E, at the top and preferably at the central portion, has a socket, as at e, (see Fig. 7) affording suitable bearing for the upright shaft F of the switch-signal, shafts F and B being at right angles, or approximately at right angles, to each other. Shaft F has rigidly mounted thereon, preferably immediately above block E, a cam, G, that projects toward cam B2, and the location and shape of cam Grelative to cam B2 is such that either cam G or cam B2, according as the 8 5 switch is operated by hand, or by a passing engine or car, is adapted to be engaged and actuated by the other cam, and in opposite directions, cam G comprising a central portion, g, and projecting members, g2, at either 9o side of said central portion and equidistant from the axis of the cam, portion g of cam G being adapted to engage, or be engaged by, the dish-shaped or concave portion of cam B2, and portions g2 of cam G being adapted to 95 engage, respectively, or be engaged by, opposite edges of cam B2, according as the latter is moved in the one direction or the other, the

surfaces of portions g2 of cam G being rounded and preferably somewhat undercut, as at 93,.

and the surfaces of portion g being rounded and convex, as at g; that is, as aforesaid,the surfaces of cams B2 and G adapted to engage each other are of such form as to render the wear of the parts as little as possible, and I would here remark that the cams are preferably made of steel. Block E is undercut, as at e', to accommodate the travel of cam B2.

I-I represents a rod or link that connects cam G with the railway-switch, (not shown) the cam being provided with ears vertically perforated, as at G', for the passage of pin or bolt O that pivotally secures the link or rod to the respective ear of the cam.

A sub-switch requires more throw than a split-switch and hence, as shown, cam G is provided at opposite sides of shaft F, with an ear having a pin or bolt-hole G the two holes being so located relative to the axis of the cam that as link or rod H is connected with the cam at one pin or bolt-hole, or the other, the throw of said link or rod will be greater or less and the mechanism rendered applicable to either a split or stub-switch, as required.

The switch-signal comprises, as heretofore,

four arms or boards, l, rigidly secured to the turned but a quarter of a levolution but toY Vchange the position of the switch, as shown in dotted and solid lines Fig. 2, a half revolution of lever C is made. Suitable mechanism is therefore provided whereby shafts B and F are turned but a quarter of a revolution during the full stroke of lever C. Referring to Fig. 5, that exhibits shaft B in I cross-section with the adjacent end of lever C in elevation, it will be observed that shaft B is provided with a shoulder or stop, as at b', and the. adjacent end of lever C is perforated or chambered, as at C for embracing shaft B, chamber C having a lateral enlargement, as at C2, forming shoulders, as at C2, at either end of lateral chamber C2, said shoul- Y ders being adapted, respectively, to engage stop or shoulder b on shaft B, according as the lever is moved in the one direction or the other, lateral chamber C2 being of such size circumferentially of shaft B that link or rod H will be thrown the proper distance and shafts B and F will makea quarter of a revolution while lever C is changed from one to the other eXtreme of its movement shown in solid and dotted lines Fig. 2, lever C making solitarily a portion of its stroke, and the arrangement of parts is preferably such that this solitary movement of lever'O will take place during the first half of the stroke of said lever when thelatter is operated by hand to replace the switch. Lever C is preferably weighted or poised, as at V.

A2 represents a cover for casing A. Lateral flanges a c a2 of casing A are perforated, respectively, and cover A2 has lateral ears or flanges as at a5 c6 correspondingly perforated, with the perforations or holes registering With ing A aforesaid for the reception of bolts, as at K, that securely fasten the part-s together. Cover A2 has a depending ange, (not shown) adapted to close the open side A of casingA, and, cover A2, in shape is like the segment of a sphere, nicely covering the mechanism inside of the casing, flange 0,6 of cover A2 being grooved on the under side to form a cap for the journal-bearing of shaft B.

The signal-shaft F is made in two sections 9 and 10, the upper section 9 being adjustable circumferentially of the lower section l0, being preferably chambered longitudinally, as at 1l, (see Fig. 6) for embracing the upper portion of the lower section 10, the latter havin g preferably a shoulder, as at l2, upon which the lower end of section 9 rests, and chamber ll and upper portion of section l0 being preferably correspondingly tapering toward their upper end so that the parts will nicely lit each other, the chambered portion of section 9 having two or more lateral holes or perforations, 13 with adjacent holes at right angles or approximately at right angles to each other, that are adapted to register with a suitable hole, as at 14, in the Lipper portion of member 10, for the reception of a pin or other suitable means, as at l5, to lock the upper section 9 in its adjusted position.

With such construction it will be observed that the switch-signal can be manipulated independently of the other mechanism, a matter of no inconsiderable importance, for, by this provision, if it were found that the proper color or signal were not presented in any particular position or situation of the switch, the upper section of the signal-shaft Acould be readily adjusted to present the color or signal required.

My improved mechanism is not only very convenient, but is durable, and exceedingly simple in construction.

Although I prefer the construction shown, wherein lever C is loosely mounted on shaft B, said lever might be rigidly mounted on said shaft and the position and shape of cam B2 and G altered to meet the requirements, Without departing from the spirit and purpose of my invention.
