Hester, Tallahassee, Fla., assignor of one-third to Robert R. Wooten, Fla. Tallahassee, Application August 23, 1934, Serial No. 741,178 5 Claims. (Cl. 246-477) This invention relates to a safety signal device n adapted to be placed on a rail of a track for the purpose of indicating to the engineer or other occupant of a train, the fact that the train should 5A be brought to a stop. It is vide a hold a device 10 moval. . a further object of the. invention to pro device of this character which serves to visual signal which can be locked to the and thus held against unauthorized re With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts herein 15 after more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed. 20 In the. accompanying drawing the preferred form of the invention has been shown. in said drawing Figure l is a view partly in side elevation and partly in section showing the signal block in po 25 sition on a track rail. Figure 2 is a plan view thereof. Figure 3 is' a section on line 3-3 Figure 1. Figure 4 is a perspective View of the filling block forming a part of the device. 30 Figure 5 is an enlarged section on line 5_5 Figure 2. Referring to they figures by characters of refer ence, I designates an elongated block which is formed of hard wood. This block has a straight 35 bottom face adapted to rest on a rail R. The top of the block is gradually inclined as indicated at 2 so as to provide a high rear end 3 and a low front end Il, the front end being preferably bev elled as shown. The ends, top and sides of the 40 block are covered with metal sheathing in the form of an inverted box 5 of sheet steel or the like and this sheathing is held to the block by means of transverse bolts or rivets 6 which are embedded in channels 'I within the upper and 45 lower faces of the block. The channels are so located and proportioned that when the rivets or bolts are seated therein portions thereof will be flush with and exposed within the respective upper and lower faces of the block. 50 The sides of the sheathing 5 are extended downwardly at the sides of rail R and are pro vided with depending wings 8 adapted tov extend between the ties T on which the rail R is mounted. A key 9 is insertable transversely through these 55 wings and is adapted to be secured at one end by a removable lock I0. The other end of the. key can be enlarged as shown so as to provide a head II. The key is located where it will extend under the rail R after the block has been placed in 5 position. Consequentlyafter the key has been secured by means of lock I0 it becomes impossible to remove the block from the rail. An opening I2 is extended downwardly through the block I and its sheathing near the high end 10 thereof and this opening is adapted to receive the shank I3 of a plate I 4 adapted to be used as a flag or visual signal. A ring I5 can be ex tended from this plate for supporting a signal lantern locked thereto if desired. l5 The shank I3 has a hole I6 extending through the lower end portion thereof. This hole is adapt ed to receive a pin I7 which can be inserted into the hole after the shank has been inserted down wardly into the opening I2. When the safety 20 signal device is placed on a rail the pin I‘I will be housed within a recess I8 in the bottom of the block and will prevent the shank from rotating and from being withdrawn from the block as long as the block is secured in position. 25 In practice the shank is fastened to the block as explained and said block is then placed on a rail at a point where it is intended to signal a train. The block should never be placed on the outside rail of a curve but should be used only on 30 a straight rail or on the inside rail of a curve. Should a train pass the signal it would not be derailed thereby. Instead one or more of the wheels would ride on the block and drop off the high end thereof back onto the rail. The severe 35 jolt to which the car would thus be subjected serves as a signal to its occupant. The occupant is also provided with a further signal in the form of the ñag or plate I4 and, under some condi tions, a lamp suspended from the ring I5. 40 Shank I3 can be of such a nature as to be bent’ over by the wheel of a car when travelling along the block so that the jolting action heretofore described will not be interfered with. By arranging the bolts or rivets 6 so that they 45 will be iiush with the top and bottom surfaces of the block I an important result is obtained. Those bolts or rivets in the bottom portion of the block constitute spaced non-yielding means for gripping the top surface of the rail while the 50 bolts or rivets in the top portion of the block con stitute spaced non-yielding means for engaging and supporting the top or load carrying portion of the sheathing. It has been found in practice that the present 55 2,061,871 2. ing the sheathing to the block, those means in the top surface of the block being exposed in said invention can be used to advantage as a “blue” flag to indicate that track repairs are being made. surface and providing spaced non-yielding sup After a crew of men have been put to ports for the sheathing, and those means in the work, the device can be attached to the track as bottom portion of the block being exposed in the bottom surface and constituting non-yielding rail engaging elements, depending wings on the sheathing adapted to extend below the rail and heretofore explained and the signal applied thereto. A signal of this type is of great value when used as stated because it cannot be removed except by the foreman or other person holding the key and unless it is removed the stoppage of 10 an approaching train will be assured. between its supporting ties, and means for ex tension under the rail and engaging the wings 10 v for locking the device to the rail. ‘What is claimed is: l.
