RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 606,197, dated June 28, 1898.

Application ned January is, 189s. sain No. 666,559. (No man.)

To all whom, t may con/Germ' Beit known that I, JOHN S. DUNN, a citizen of the United States, and a resident of Portage, in the county of Columbia and State ofV Wisconsin, have invented certain new and useful Improvements in Railway Signals; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple economical signal for temporary use along railway-lines, the same being especially designed to take the place of the ordinary staff and flag commonly employed.

It therefore consists in certain peculiarities of construction and combination of parts hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

Figure l of the drawings represents a partlysectional front elevation of one form of my improved signal and holder for the same positioned along a railway-line; Fig. 2, a partlybroken side elevation of the signal-staff shown in the preceding gure, the flag-rod portion.

of the signal being shown in transverse section; Fig. 3, a plan view of a portion of the signal-holder shown in the rst figure; and Fig. 4, a front elevation illustrating another form of signal in connection with said holder, the latter being shown in section.

Referring by letter to the drawings, A represents a portable horizontal arm having one end thereof bent in the form of a hook b for engagement of the inner flange of a trackrail, and superimposed on the arm is ajawplate B for engagement with the outer flange of the track-rail. The arm is shown provided with a longitudinal slot c, and a bolt t Y engages this slot and an aperture in the jawplate, a set-nut e being run on the bolt to hold said jaw-plate in adjusted position longitudinally of said arm. The other end of the arm is provided with a vertical aperture f, the contour of this aperture being preferably angular and oblong, as herein shown. The aperture in the arm is for the engagement of a shank having corresponding contour in horizontal section, and this shank may b e a metal-point fixture C at the lower end of a wooden sta-ff D, or it may be a metal rod C', having a signal-target D' fast thereon. As herein shown, a set-screw g may be employedl housing. Made fast tothe rod is one edge of a signal-flag F,'and the latter being furled on said rod both maybe swung into said housing out of the way. Y.

A plate G, pivoted at its lower end to staff D, constitutes a closure for the housing, and a transverse notch h in the upper portion of the plate is for engagement of the aforesaid rod when the latter is swung out to horizontal position, the Hag being then unfurled to serve as a signal. An eart'e'xtends from the notched end of plate G, and when the latter is in position parallel to staff Dfsaid ear is,

parallel with another ear j, extending from said staff. These ears are provided with registering apertures, and a hook H, in permanent flexible connection with the staff, is engaged with the apertures to hold the plate parallel with said staff. However, other suitable means may be employed for the same purpose.

From the foregoing it will be vunderstood that when theflag-signal is not required for use it may be incased in its staff, as shown by dotted lines, Fig. l, so as not to become soiled or torn, and owing to the fact that the flag is suspended from a horizontal rod when in use it cannot become wound about said staff.l It also follows that said iiag will be generally more prominent than those ordinarily employed as a temporary signal.

In the absenceof the holder, comprising the arm A and adjustable jaw-plate B, the stai D may be set up in the ground along the line of a railway, and the end of its shank is shown pointed to facilitate the placing of the signal; but a holder attachable to a track-rail is necessary in conjunction with the all-metal target-signal. (Shown in Fig. et.)

By having the aperture in the outer end of the holder and the shank of the signal of predetermined oblong contour it is impossible to connect said holder and shank without setting said signal so as to display in a direction transversely of the adjacent vrailway-track. It also follows that the signal is not liable to IOO topple, especially it its shank be operated upon by a set-screw.

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

1. A portable horizontal arm having one end thereof bent in the form of a hook engageable with the'inner flange of a track-rail, a jaw adjustable on the arm longitudinally thereof to engage the outer flan ge of the trackrail, suitable means for securing the jaw in adjusted position, and a signal having detachable connection with said arm.

2. A'portable horizontal arm having one end thereof bent in the form of a hook engageable with the innerfiange of a track-rail and its other end provided with an oblong aperture, a jaw adjustable on the arm' longitudinally thereof to engage the outer ilange ot' the track-rail, suitable means for securing the jaw in adjusted position, and a signal provided with a shank having detachable match fit in the aforesaid aperture.

3. A horizontal arm having one end in the form of a hook engageable with the inner fiange of a track-rail and its other end provided with a suitable aperture, a jaw adjustable on the arm longitudinally thereof to engage the outer flange of the track-rail', suitable means for securing the jaw in adjusted position, a signal provided With a shank having detachable match fit in the aforesaid ap-V erture, and a set-screw arranged to maintain the engagement of the sign alshank with saidV arm.

4. A longitudinally-slotted arm having one end in the form of a hook en gageable with the inner Hange of a track-rail, a jaw loose on the arm for engagement with the outer flange of the track-rail, a bolt extending through the arn1-slot and an aperture in the jaw, a set-nut run on the bolt, and a signal having detachable connection with said arm.

5. A railway-signal comprising astaft longitudinall y recessed to form a housing, a rod pivoted at one end within the upper part of the housing, a flag made fast at one edge to the rod, a pivotal closure-plate for the housing provided With a transverse rod-supporting notch, and suitable means for fastening the closure-plate parallel to the statt'.

6. ArailWay-signal comprising a staff longitudinally recessed yto form a housing, a rod pivoted at one end Within the upper part of the housing, a flag made fast at one edge to the rod, a pivotal closure-plate for the housing provided with a transverse rod-supporting notch, apertured matching ears on said staff and plate, and a hook in' permanent flexible connection with the aforesaid staff for engagement with said ears.

7. A railwaysignal comprising a staff longitudinally recessed to form a housing, a rod pivoted at one end Within the upper part of the housing, a flag made fast at one edge to the rod, a pivotal closure-plate for the housing, suitable means for fastening the closureplate parallel to said stam-and a shank on said rod, in combination with a holder organized for temporary connection with a trackrail and provided with an aperture for the engagement of the staifshank.

In testimony that I claim the foregoing I have hereunto set my hand, at Portage, in the county of Columbia and State of lVisconsin, in the presence of two witnesses.
