COMBINED TIE PLATE AND RAIL ANTICREEPER I Application filed March 19, 1923. Serial No. 626,084.

To all whom it may concern:

Be it known that I, JAooB A. HYLE, citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented cer tain new and useful Improvements in Combined Tie Platesand Rail Anticreepers, of which the following is a specification.

This invention relates to a novel anticreeper tie plate and is especially designed for the purposes of successfully preventing the creeping and spreading of the rails upon a railway track, as well as toretain the track rails in their proper alignment, and to in- 5 sure a substantially perfect gauge being ree tained on both sides of the rail under any and all conditions. The prime object of the invention is to provide a novel, simple, durable, economical, meritorious and thoroughly 'efficient com bined tie plate and anti-creeper for the track rails of steam and other railway road beds.

Another object of the invention is to provide a tie plate for receiving the track rails, the plate being providedwith novel locking means for engaging the rails, said locking means including balls which tend to move in tighter locking engagement with the base portion ofthe rails during vibration of said rails.

Another object of the invention is to so construct my improved. tie plate, that the locking meanswill beprevented from mov- 4 ing out of engagement with the base ofithe "36 track rail under allconditions.

Afurther objectof the invention is the provision of. a railway tie plate which can be rigidly secured to the usual'cross-tie, and

I which embodies aplurality of yielding lugs 40 adapted to overlap the upper surface of the track railbase, the inner surface of each lug being formed with means for the reception and retention of the automatically movable locking means.

The foregoing and such other objects as mayappear from the ensuing description are accomplished by the construction, ar- -rangement,.locatio'n and combination of the parts hereinafter more fully described, illustrated in the accompanying drawings, and

particularly pointed .outinlthe claims appended hereto, it being understood that slight changes in the precise proportions and minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part'of this specification, it will be seen that: Figure 1. is a plan of the improvedplate embodying my invention in its normal position beneath a railroad rail, showing the rail broken away and the locking means in dotted lines, Figure 2 is a plan showing the position of the tie plate with respectto the rail before being forced into its normalposition.

Figure 3 is a transverse section taken in the plane of the dottedlines 8-3, Fig. 1, looking in the direction of the arrows, and showing the movable locking 'means' embraced by oneof the clamping lugs.

Figure 4c is a side elevation showing the platedetached from the rail. 1 igure 5 is a plan showing a blank form of the plate, and showing the depressions formed in the upper face of the plate before the rail clamping lugs are formed.

Figure 6 s a cross-section taken in the plane of the dotted lines 6-6, Fig. 4, looking in the direction of the arrows.

Figure 7 is an enlarged cross-section through one of the clamping lugs taken in the plane of the dotted lines 77, Fig. 4:, looking in the'direction of the arrow and showing the movable locking means resting onthe recessed portionof said lug, and Figure 8 is a slightly enlarged section taken in the plane of the dotted lines 8-8, Fig. 3, showing the locking means in engagement withtherecessed inner race of one of the clamping lugs and the thebase of the rail;

In the embodiment of my invention as illustrated the numeral 1 designates the metallic plate preferably formed from rolled I steel of the desired quality and any suitable dimensions, with a smooth'flat lower surface upper surface of having a thickened central body portion 2,

the upper surface being beveled or gradually tapered from its thickened portion'to each outer end 3 thereof. Said plate is then heated to the proper degree and while in its heated state a suitable die is placed onthe face of the-plate'near its'diagonally opposite corners and by "a single blow of a suitable power hammer or forgin machine, the i recesses or depressions 4 ofsu stantially the shape shown iniFig. 5 are formed therein,

suitable spike openings 5 are then punched therethrough by the proper machine, and the a plate is then cut through in the plane of the V dotted lines shown in Fig. 5, after which the plate, in its'heated condition, is placed in a suitable: machine and the said out portions of the plate are bent or turned upwardly and inwardly to form yielding lugs 5, adapted to tightly clamp the upper surface. ofv the rail base 6, the outer surface of each lug being formed with a strengthening rib 7, and the inner face'of each lug having a recess or depression t formed therein with a substantially straight central portion 8, terminating at its outer end in semi-circular,

form 9, and at its inner end with a lateral extension at each side thereof which is graduallyshallowed toward its outer ends, as clearly shown in Fig. 8, said depression forming a pocket for the reception of aplurality of case hardened steel movable balls 10, adapted ,to contact with the upper'face of the base of the track rail for the purpose hereinafterdescribed.

- By. reference to Fig. 2 it will be seenthat theplate is first placed beneath the rail 11 substantially into the position shown, after 7 which by striking the outer edge 12 of said use plate with a sledge or heavy hammer the lower beveled faces of'the lugs will be caused to yieldingly slide inwardly to overlap the upper surface ofthe rail base until the plate assumes its normal position beneath thebase of therail, as shown in Figs. land 3, thereby rigidly and securely clamp- I ing the plate to the rail base, after which the steel locking and wedging balls, preferably three of said balls, are inserted into the outer end of the pocket formed by the recess or depression ineach of the lugs, which balls'assume substantially theposition shown in Figs. 1 and 7 and rest in contact with the rail base. In removing the plate from the track rail after the fastening spikes shall have been withdrawn it is simply necessary to turn the railover, and if necessary tap said rail-'or-plate-withahammer and the steel balls will drop out of the pocket, then by striking the-edge 13' of the plate with a sledge or heavy'hammertheplate maybe easily detached.

It will be readily perceived that since the late'ralextensions of each recess or depresthe shallow surfaceythereby causing the ball tolbecome tightly wedged against the rail base,1thussuccessfully preventing'anyj creep in}; 'ofthe rail, at the-same 'timerallowing 7 sufficient movement to permit the wave moe tion of the rail usually caused by heavy rolling stock passing over the track rails.

While I have shown three steel locking and wedging balls, it will be obvious that only one or two of these balls may be utilized for elfecting the desired purpose and that the saidlocking means will-*serve to make it practically impossible for the rails to creep either way when employed in connection with a-singleor double track having traffic in one ortwo directions.

By my novel construction and arrangement of combined tie plate and rail anticreeper it willbe evident, that a compara tivelyeconomical product is formed, which. is adapted to effectualy serve'to prevent the accidental spreading of the rails; to insure a. perfect guage and alinement of the rails on each side thereof at all times; that :a smaller percentage of these plates will be required to each railthan those usually employed, thereby'creating a considerable saving per mile of road'bed, and efficiently prevents the a'nt-i-creepingof the track rails.

It will be understood that asthe plate is being forced into itsnorma'l position beneath the baseof therail the overlappinglugs made from the proper quality of steel 'are so formed that they willspring or yield gradually as they are caused to slidevupon the inclinedupper surface of the rail base,

thereby causing the inward portion of each lug to grip. the rail with more intensity when it is caused to assume its final and proper position beneath the base of the rail.

Havingthus described :my invention what l claim and desire to'secure by Letters Patent-'isz- 1 1.
