1 '0 all whom it may concern.

Be it known that I, SAMUEL G. RICHTER, a citizen of the United States, residing at Doltons Station, in the county of Cook and State of Illinois, have invented new and useful Improvements in Turn-Table Locks and Derailer Controls, of which the following is a full, clear, and exactdescription.

My invention relates to safety devices for railroad tracks, and particularly for preventing the wrecking of engines, locomotires and railway cars in turntable pits and at swinging bridges.

The object of my invention is to derail a locomotive or a car before it can reach the pit of an open turntable or the stream or depression crossed by a bridge, at such a distance therefrom that the wrecking of the same will be avoided, and it is also an object of my invention to do this by comparatively simple means which will set the derailer on the ball of the track at the same time the bolt or locking device of said turntable or bridge is manipulated to permit the latter to be moved and unset it when the turntable or bridge is locked. These and other objccts are accomplished by the means hereinafter fully described, and as particularly set forth in the claims.

In the drawings:

Figure 1 is a plan view of broken away portions of the track approach and the end of a turntable showing my improvements applied thereto.

Fig. 2 is a longitudinal view of the same taken on dotted line 2-2, Fig. 1.

Fig. 3 is a longitudinal section taken on dotted line 3-3, Fig. 1, drawn to a larger scale.

Fig. 1 is a horizontal section taken on dotted line 4l, Fig. 3.

Fig. 5 is a transverse vertical section taken on dotted line 55, Fig. 1, drawn to the same scale as Fig. 3.

Fig. 6 shows a transverse section of one of the rails of the approaching track looking toward the derailer, which latter is shown in dotted lines, while its seat is shown in solid lines.

Referring to the drawings, A represents a circular turntable pit; B ,a turntable having ties b, 7), connecting the parallel beams of the frame thereof; C, C, the rails mounted on said ties and D, D, the rails of the track approaching said pit.

My improvements comprise, broadly speaking, a longitudinally reciprocable bolt 8, which is mounted on the turntable between and parallel to rails C, C; a tubular casing 9 arranged longitudinally between tracks D, D, into which said bolt is adapted to be shot; a derailer 10 located fifty to seventyfive feet away from pit A, and mechanism that utilizes the thrust of the bolt when it is shot into said tubular casing 9 to move the derailer off of the track so as to leave an open track when the turntable is locked to bring rails C, C, and D, D, in alinement preparatory to running a locomotive or car onto said turntable, and to reset said derailer on the track when the bolt is withdrawn from said casing and the turntable is moved so as to carry rails C, C, out of alinement with rails D, D, of said approaching track.

As shown in the drawings, bolt Sis a comparatively long metal bar that is mounted upon the ties parallel to rails C and reciprocated through the medium of a link 12 connecting it to an arm 13, which latter projects upwardly from a rock-shaft 1 1 journaled in suitable hangers 15 secured to and depending down from the longitudinal beams or equivalent structure of the frame of the turntable, substantially as shown in Fig. 2 of the drawings. Bolt 8 is placed between and its reciprocable movement is guided by means of guide-

plates

16, 16, and 17, 17; guide-plates 16 having flanges that overlap the longitudinal edges of the bolt and guide-plates 17 having flanges upon which said bolt rests. This arrangement of the overlapping and underlapping flanges of guide-

plates

16 and 17 is provided for the purpose of permitting of a certain limited vertical play of the end of bolt 8 nearest the end of the turntable, where the bolt has securely mounted thereon a longitudinally disposed plate 18, the advanced end of which extends beyond the adjacent end of the bolt and is formed into a hook 19, the extremity of which points downward and terminates in a horizontal plane a suitable distance above the horizontal plane of the top of the bolt. If desired, this hook may be strengthened by the roe employment of ribs arising from its longitudinal edges and the corresponding edges of plate 18, substantially as shown.

Tubular casing 9 is, preferably, rectangular in cross-section, and its base-plate or bottom 20 extends beyond the end thereof into which the hooked end of the bolt is adapted to enter, and when. the casing is arranged in proper position the end of this extension terminates at the edge of the pit, substantially as shown in Fig. 3, and is, preferably, slightly beveled. The adjacent end of the bolt is provided with a slightly undercut bevelso that when said bolt is shot toward the adjacent open end or mouth of easing 9 it will be slightly raised.

The inner surfaces of the vertical walls and the roof of the casing are beveled at its mouth, and the upper portion of said vertical walls are made thicker and provided with longitudinal runways 22 that extend from its rear end to very near its mouth. Near said mouth these runways are inclined downward and terminate in and communicate with the longitudinal grooves in the said Vertical walls next the floor of the casing that result from and are incidental to making'the upper portions of said walls thicker. These runways may be made in any other way, but, considering the rough usage to which the casing is subjected, I prefer to make them as hereinbefore described.

Arranged and movable longitudinal within casing 9 is a dog 23 consisting of a suitably shaped metal bar of a length substantially corresponding to that of the bore of the casing. The end of this dog nearest the bolt is provided with a transverse ric ge 2-]: projecting upward therefrom, the ends of which are extended to provide

lugs

25, 25. The under sides of these lugs are in a horizontal plane corresponding to the lower edge of the thickened upper portion of the vertical walls of the casing, and the rear portions of these bottom edges are beveled, as shown at 26, Fig. 3 of the drawings. The rear end of dog 23 is connected by a longitudinally extending rod or pipe line 27 of about fifty to seventy-five feet in. length to the longer arm of a bell-crank 28, which latter is fulcrumed at its angle to a suitable pivotal stud 29 secured to and arising from a plate secured to one end of the ties of the track, and the shorter arm of this bell-crank is pivotally connected to the adjacent end of a transversely extending link 30 whose opposite end is connected to a lug projecting down from the derail block 31, the opposite end of which latter is suitably shaped to derail a locomotive or car when it is moved transversely onto the tread of rail D when Letters Patent of the United States, g 'anted to S. W. Hayes, for derail Oct. 31, 1911, No. 1,007,102 and June 6, 1916, No. 1,185,663 and as shown in outline in Fig. 6 of the drawings, but it will be understood that any other derailing block or device which can be moved laterally to set on the tread of the rail to derail a locomotive or car passing over it will answer the purpose of my invention just as well as said block 31, and I, therefore, do not wish to be confined to the use of the same.

Casing 9 is retained in the position shown in the drawings in alinement with belt 8 by means of triangular shaped guide-

plates

32, 32, between which the end of the casing nearest the bolt is placed, and in order to permit of a limited vertical play of said easing I have provided the vertical retaining walls 33 of said plates with vertically elongated guide-openings 3st into which guidelugs 85, 35, projecting laterally from said casing, enter and have a limited vertical play.

In order to operate my invention, rockshaft 1% is moved through the medium of a lever 36 secured to and projecting from one end thereof in one direction and imparts a movement to said shaft and to arm 13, which, through the medium of link 12, shoots bolt 8 toward casing 9 so that the hooked end 19 thereof will enter the adjacent mouth of the same. IVhen said bolt has been shot forward a sufiicient distance the end of the same below the horizontal plane of the extremity of hook 19 will come in contact with the adjacent end of dog 23 and as it continues to move in the same direction it moves the dog rearwardly, and lugs 25 at the ends of ridge 24 thereof enter the adjacent ends of runways 22 and raise the adjacent end of said dog so that said ridge enters within the embrace of hook 1S) and interlocks therewith. Dog 23 as it is thus moved to the rear moves pipe line 27 longitudinally and imparts motion to bellcrank 28, which latter through the medium of link 30 moves the derailing block off of rail D of the approaching track. lVhen the turntable is thus locked so that the approaching track is open and alines with the track on the turntable, the locomotive or car can be run onto the turntable, and when in proper position the latter can be unlocked and turned to bring it into alinement with some other track that approaches the turntable pit and the locomotive or car can be run onto the same.

In order to unlock the turntable, lever 36 is moved so as to rock shaft 1 1 in the opposite direction to that just described, and through the medium of arm 13 and link 12 withdraws bolt 8 from the casing. As the hooked end of this bolt is thus withdrawn it pulls dog 23 along with it until the ridged end thereof is directed downward by the inclined forward portion of runways 22, whereupon it releases its hold upon the bolt, which latter continues its withdrawal movement until the contiguous end thereof passes and clears the junction between'the end of the turntable and the edge of the pit. As dog 23 is pulled longitudinally forward toward the pit by the hooked end of the bolt, as just stated, pipe line 27 moves bell-crank so that it, through the medium of link 30 moves the derail block so that the derailed end thereof is reset on the ball of rail D. 7 hen the derail block is in this reset position, any locomotive or car attempting to pass over the same will be derailed and immediately stopped by the engineer, and thus prevented from pitching into the turntable pit and wrecked.
