RAILWAY-SIGNAL POST.

Specification of Letters Patent. Ptelltedvug; 19, `19113.

Application filed November 23, 1910. Serial` No. 593,803. r

To ali whom t may Concern.'

Be it known that I, CHARLES F. MAssEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Signal.

Posts, of whichthe following isa specification.

My invention relates '.to` railway signal posts and contemplates improved construction and arrangement.

Among the important objects of my invention are to provide a post which is entirely constructed of cement-itious material such as concrete through which extends longitudinally a metallicpipe which serves both cas an electrical conductor for wires and also as a reinforce for the concrete; to provide a head frame for the post formed integral vtherewith of concrete and providing a compartment for receiving signal lamps or other apparatus or for accommodating semaphore apparatus; to provide a dust and weather-proof compartment at an intermediate part of the post for receiving relays or other electrical apparatus, the walls of which compartment are formed integrally of concrete with the post; to pro-vide an improved bed structure for the post, which structure is built up integrally of concrete and which, besides affording av seat or anchorage bed for the post, is arranged to provide a Well or housing for batteries; and in general to provide a construction and arrangement which will better adapt signal posts for usage in up-to-date railway signaling systems.

In the drawing which accompanies this specification Figure 1 is a front elevational view of the post, Fig.` 2 is a sectional view taken on plane 2 2, Fig. 1, Fig. 3 is an en larged sectional View taken on plane 3-3, Fig. 1, and Fig. 4 is a cross sectional view of the post taken on plane 4-4, Fig. 1 to illustrate more clearly the concrete reinforcing arrangement.

The post 5 may be ofrectangular'cross section, as indicated in Fig. 4, and has the widened or enlarged base 6 and at its top is expanded to form the annular top frame 7 of substantially rectangular cross-section, as indicated in Fig'. 2. At an intermediate part the post is hollowed and expanded laterally and forwardly to provide top and bottom walls 8 and 9 and side walls for a compartment 12. The post proper, the top an integral structure preferably builtup'of concrete C. Extending centrally and longitudinally through the post is a metallic pipe 13, this. pipe serving as a conduit for electric frame 7, and the walls 8, 9, 10 and 11 form circuit wires. The post may be reinforced by longitudinal metallic bars 14, suitably cross connected ais-intervals by wires .15, as indicated ln Fig. 4, these bars preferably being extended through the body of .the annular top frame 7, as indicated in Fig. 2, in order to.. strengthen this top frame. Thepipe 13 is interrupted to connect with the upper and lower ends of compartmentl v'12.` The pipe may also have the sleeve 16 interposed, from which an outlet. pipe-.17 leads to Ia frame 18 suitably secured to a. face off-the post and accommodating electric bell mechanism 19. Azs best shown in Fig. 1, the ypipe A13 terminates at its upper end in a. fourway fitting 2() from whose side outlets exf tend se-micircular pipe sections 21 and 211 through the respective halves of the ,concrete top frame 7, the upper ends of :the pipe sections connecting in the lateral -outlets of the fourway fitting22 at'the top of frame 7. A stud plate 23,-extends from .the upper outlet of fitting 22l andthrough a boss or extension 24 at the top of -frame 7, this boss or extension serving to support an electrically controlled signalbell v25.- The lower end of the pipe has the lateral outlet 26 through which the external ,circuits may enter.

The pipe 13 assists in reinforcing the. concrete of'which the post is constructed, and lil ewise the pipe sections 21 and 21 will assist in strengthening and reinforcing the top frame 7. The reinforcing of the post may follow along the walls of compartment 12 to strengthen these walls. This compartment serves for the accommodation of any desired electrical apparatus A, such as relays and line protecting mechanism, and in order to render this compartment more dust-proof and weather tight it is preferably lined with some suitable material 27 and provided with a main door 28 and an auxiliary door 29. The main door is hinged at 30 to one side Wall of the compartment, and may be locked by suitable lock mechanism 31. Interposed between the main door and the auxiliary door is a compression spring 32 which, when the main door is closed, bears against the auxiliary door to securely hold the auxiliary door to the lining 27, a gasket 33 of suitable material such as felt being preferably interposed between the auxiliary door and the front edges of the lining 27. Thus, when the doors are closed no dust, dirt or moisture can enter compartment 12, and the electrical 'apparatus in said compartment,is therefore amply protected. The top Wall 8 overhangs the main door, as indicated at 34, to form an eave, and in theunder side of this eave is provided a drip groove 35.

The frame 7 at its opposite inner edges has gro-oves 37 and 38 forming aseat for glass disks 39 and 40, these disks, together with the frame 7, forming an inclosed compartment 41 in which, as shown, is accom` modated an electric lamp 42, which, as shown, may be suspended by pipe 43 from the top fitting 24. The glass disk may have painted thereon any suitable legends7 such as indicatedl in Fig. l, and the disks are held in place in their grooves by clips 44 extending from the frame 7. Y

As indicated in Fig. 2, the post is supported in upright position by an integral concrete structure S which provides a pocket 45 for the base of the post and Which also provides a compartment 46 in which batteries ma be stored or in which electrical distributing apparatus may be installed,

-the compartment being accessible through an'opening 47 having a cover 48. The extension 26 at the lowerend of the pipe leads into compartment 46. Where permissible the integral foundation structure providing both a well and a support for the post will be installed. In other cases the post can be` set in an ordinary foundation and a separate Well installed at a suitable pointand connected with the conduit pipe in the signal post. f

The post of my invention is of very rigid and permanent construction which is not affected by the elements. The various relays and other controlling mechanism are securely housed directly on the post adjacent the signaling apparatus which they control and are Well protected against the weather and particularlyv dust, cinders, soot, smoke, etc. Where the post bed and the battery well are part of an integral structure the Well and post Will serve mutually to support each other in proper position.

I do not desire to be limited to the precise construction and arrangement which I have shown, as changes and modifications are of course possible which would still come Within the scope of my invention, and

I therefore claim the following:

A railway signaling post structure entirely of concrete and expanded at intermediate parts to form a compartment for accommodating signaling mechanism, the top of said concrete structure being expanded into the form of a circular head, transparent sides applied to said circular head to form therewith a compartment for housing signaling mechanism, a pipe extending entirely around and Within the material of the circular head to form a reinforce therefor, a pipe extending longitudinally through said post and communicating at its upper end with the interior of the head piping, an outlet from said head piping to the head compartment, and a concrete supporting base lhaving a socket for receiving the lower` end of said ost. p Inwitness hereof, I hereunto subscribe my name this 21st day of November, A. D., 1910.
