Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed May 18, 1904. Serial No. 208.626.

To (all wit/mt it may concern:

Be it known that we, BARNEY-SAMUELS and DAVID SAMUELS, citizens of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in RailwaySignals, of which the following is a specification.

Our invention relates to improvements in railway-signals and the essential features of the invention comprise two opaque members, one of which is stationary and contains two permanent positions radiating froma common center, while the other is pivotally mounted upon the stationary member in order that it may alternately obscure or cover the positions indicated thereon, so that but one position can be read at a time.

The two positions may be shown by either colors or openings in the stationary member, and when openings are employed the signal may be read from both sides of the stationary member with the employment of but one pivoted member.

The positions may indicate safety and danger, which terms we will use throughout the specification; but of course in practice they may indicate caution, &c.

Signals displayed by ordinary semaphoreblades are frequently rendered very indistinct by backgrounds corresponding in color to said bladesfor instance, if a red blade be in the line of sight with a red brick building or a green blade be placed in front of a tree it will be diflicult to distinguish the blade. By providing a stationary opaque member of a decided contrast in color to the two positions indicated thereon the exposed position will show with great distinctness, so that it can be easily read at a distance.

The invention also consists in minor features hereinafter described and claimed, and in order that it may be fully understood reference will now be made to the accompanying drawings, in which Figure 1 represents a front elevation of the signal inclosed in a case. Fig. 2 is a vertical section of the case, taken on line H II of Fig. 4. Fig. 3 is a vertical section of the signal in the rear of the blind on line 111 III of Fig. 4. Fig. 4 is a transverse section taken on line TV IV of Fig. 1. Fig. 5 shows a modified arrangement of the blind and the two positions on the stationary member. Fig. 6 contains a modification of theiblind.

In said drawings, 1 designates the stationary member, which may be rectangular, as shown, or of any other desired form and comprises side walls 1, top and bottom walls 2 and 3, and a front and rear wall 4 and 5, which latter preferablyconsist of glass.

6 designates a centrally-disposed post extending upwardly from bottom wall 3 and provided at its upper end with a bracket 7 and a transverse shaft 8, journaled at its opposite ends in said bracket and the upper end of the post.

Glass 4 is clear, with the exception of two irregular-shaped opaque portions, preferably consisting of black and white paint 9 and 10, respectively. Glass 5 is preferably rendered opaque with black paint throughout its surface, except at the two permanent positions 11 and 12,which it contains, and a circular portion 13, arranged between the reduced portions of said positions. Position 11 extends diagonally across wall 5 and consists in a "reduced upper portion 14 and an enlarged lower portion 15. Position 12 extends horizontally across wall 5 and is similar in form to position 11, which latter it intersects at a point in line with the axis of shaft 8.

Position 11, which indicates safety, is preferably shown throughout its length with white paint, with the exception of a clear irregular portion 16. Position 12, which indicates danger, is preferably painted red throughout its length, except where interrupted by the irregular clear portion 16. The white and red paints indicating positions 11 and 12, respectively, are translucent for the admission of light from the rear,which brings out said portions with great distinctness.

17 designates the pivoted member or blind, mounted upon shaft 8 and provided at its narrow portion with oppositely-disposed annular openings 18, preferably glazed with mica or other translucent material corresponding in color with. positions 11 and 12, so that a light placed in the rear of the clear circular portion 13 will show through the glazed opening 8, registering therewith, and

thus provide an efficient signal for night use.

Blind 17 corresponds in contour with positions 11 and 12,and its enlarged portion 19 is connected by a narrow diagonal portion 20 to its opposite narrow portion 21. Diagonal portion 20 is preferably composed of translucent material and provided at its opposite sides with irregular-shaped portions 22, forming an auxiliary blind, consisting, preferably, of translucent material correspending in color with positions 12, so that when said position is exposed points 16" of clear portion 16 will be covered by said auxiliary blind. Consequently the danger posi tion will be interrupted only by white portions 23 24 on the diagonal portion 20 and the adjoining portion of the blind. Portions 24 are triangular and register with the hori- Zontal edges 14 15 of position 11 when the latter is exposed in order that the central portion of the same will be interrupted only by the red on opposite sides of portion 23. When the blind is rotated to a horizontal position, the opposite portions of the auxiliary blind are moved to a registering position with. the opaque portions 9 and 10 on wall 4, so they will not detract from the clearness of the safety position.

Blind 17 is oscillated by a connecting-rod 25, pivotally secured at its opposite ends to diagonal portion 20 and a suitable motor 26, resting on bottom wall 3. Blind 17 is opaque and corresponds in color with the opaque portion of wall 5. Its enlarged portion 19 is preferably made heavier than its narrow portion 21, so the blind will automatically assume the position shown in Figs. 1 and 2, and .thus expose the danger position should accident occur to motor 26.

In practice the greater portion of glass walls 4 and 5 may be protected by a covering of wood or sheet metal cut out to expose the two positions 11. and 12.

In the modification shown in Fig. 5 the case is dispensed with and stationary member 5 which in this instance is preferably composed of wood or sheet metal, has two openings 11 12 to indicate the safety and danger positions, respectively. Said openings radiate from a common center 8", where blind 17 is pivotally secured.

The modfication shown in Fig. 6 is similar to that shown in Fig. 5, with the exception that blind. 17 has two members 17 17, respectively. By employing this form of blind less motive power is required for its operation, as it only moves a distance equal to the width of positions 11 and 11 in order to alternately expose the same.

ary member indicating two permanent intersecting positions, and a blind pivotally mounted. upon said member and adapted to alternately obscure or cover said positions.

4. A signal comprising an opaque stationary member indicating two permanent positions radiating from a common center, and a blind pivotally mounted upon said member and adapted to alternately obscure or cover said positions.

5. A signal comprising an opaque stationary member indicating two permanent positions, a blind pivotally mounted upon said member and adapted to alternately obscure or cover said positions, and an auxiliary blind formed integral with the first-mentioned blind to increase the clearness of one of the positions.

6. A signal comprising an opaque stationary member indicating two permanent positions, a blind pivotally mounted upon said member and adapted to alternately obscure or cover said positions, and a translucent auxiliary blind formed integral with the first-mentioned blind to increase the clearness of one of the positions.

7. A signal comprising an opaque stationary member indicating two permanent positions, and a blind pivotally mounted upon said member and provided with two arms adapted to alternately obscure or cover said positions.

In testimony whereof we afliX our signatures in the presence of two witnesses.
