Claims.

This invention relates to a rail anchor designed primarily for use in connection with railway track rails, but it is to be understood that an anchor in accordance with this invention is for employment in any connection for which it may be found applicable.

The invention aims to provide, in a manner as hereinafter set forth, an anchor of the class referred to, to prevent the creeping of a railway track rail when installed relative to the latter.

The invention further aims to provide, in a manner as hereinafter set forth, a rail anchor having inherent means for locking it to the base of a railway track rail when the anchor is installed.

The invention further aims to provide, in a manner as hereinafter set forth, a rail anchor having inherent means for looking it in overlapped relation with respect to the base of a railway track rail.

The invention further aims to provide, in a manner as hereinafter set forth, a rail anchor including a base, a clamping jaw at one end of the latter for overlapping having a tight fit with the lower and upper faces of one side of the base flange of a railway track rail, and means extending from the other end of the base and engaging with the edge of the other side of the base flange of the railway rail for locking the jaw in position whereby the anchor will be fixedly secured to the railway track rail in depending relation with respect to the latter and to the cross tie to prevent the rail from creeping.

The invention further aims to provide, in a manner as hereinafter set forth, an anchor for the purpose referred to, including a jaw for overlapping the base flange of the railway rail and means for locking the jaw in such position.

The invention further aims -to provide, in a manner as hereinafter set forth, an anchor for the purpose referred to, and of a form which,

' when installed relative to a railway track rail,

will prevent tie plate contact.

The invention further aims to provide, in a manner as hereinafter set forth, a rail anchor which is simple in construction and arrangement, strong, durable, compact, thoroughly efficient in its use, readily installed with respect to a railway track rail without tie plate contact, and comparatively inexpensive to manufacture.

Embodylng the aims aforesaid, and others which may be hereinafter set forth, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which will come within the scope of the invention, as claimed.

In the drawing:

Figure 1 is a vertical sectional view of a railway track rail, with the latter mounted on a tie plate supported upon a cross tie, and showing the adaptation of a rail anchor, in accordance with this invention, with respect to the track rail, tie plate and cross tie, the anchor plate and tie being in side elevation.

Figure 2 is atop plan view of the structure shown by Figure 1, with the rail shown in dot and dash lines; and

Figure 3 is a side elevation of the anchor.

With reference to the drawing, a railway track rail is generally indicated at 5 and its head, web and base are indicated at 6, 1 and 8 respectively. As is well known, the base 8 is in the form of a pair of oppositely extending flanges 9, III disposed in lateral relation with respect to the web I. The edges of the flanges 9, ID, are indicated at H, l2 respectively. The upper faces of the flanges 9, l0 incline downwardly from the web I to the edges II and I2 respectively. The lower face of the base 8 is flat and is shown seated upon a metallic tie plate l2 mounted on a wooden cross tie [3. The rail 9 and tie plate l2 are secured to the cross tie l3 in a known manner.

The rail anchor, in accordance with this invention, is a one-piece body of any suitable metallic material. Preferably, the anchor will be made of any suitable carbon steel to give desired strength and resiliency when it is installed relative to the rail. The anchor includes a horizontally disposed base It, a clamping jaw l5 and a locking arm Hi.

The base l4 gradually decreases in width from the outer end H to the inner end Ill. The outer end H is squared. The inner end I8 is slightly rounded. The top of the base is of greater length than the bottom IS. The latter is fiat. The base is substantially of trapezium contour in plan and of substantially rectangular form in side elevation with the inner end of each side upon a slight curve. The base has its width and length greater than the height thereof. The base H has the outer portion 20 of the top disposed at a higher level than the inner portion 2| thereof. The portions 20, 2| are separated by a transverse groove 22 of concave contour. The providing of the top of the base M of two levels forms the base of a high portion and a low portion.

The body of the jaw I5 is of less cross sectional width than the transverse cross sectional width 01' said base I 4. The jaw I5 includes a straight lower portion 23 which is integral at the lower side with the top portion 20 of base I4, and it is spaced equi-distant from the sides of base I4. The inner end of portion 23 is curved and forms an upward continuation of the wall of the groove 22. The jaw I5 includes a vertically disposed intermediate or outer portion 24 of arcuate contour and which may be termed a half round portion. The jaw I5 includes an upper portion 25 which is downwardly inclined to the horizontal, and it is disposed over, spaced from and of greater length than the portion 23. The inner terminal part of the said jaw portion 25 is arranged in inwardly extended relation with respect to the jaw portion 23. The outer end of the latter merges into the lower end of jaw portion 24. The outer end of jaw portion 25 merges into the upper end of jaw portion 24. The jaw portion 25 gradually increases in width from its point or mergence with jaw portion 24 towards its free end.

The upper face or edge of the jaw portion 23 is straight and it is employed for binding against the lower face of the base 8 of the rail 5. The inner face or edge of jaw portion 24 is curved and it is to oppose the outer edge of a flange 9 or III. The inner face or edge of jaw portion 25 has an inclined front part 25 and a straight rear part 21. The latter is for riding and binding on the upper surface of a flange 9 or III. The normal position of the jaw I5 is as shown by Figure 3, and when positioned on a flange 9 or III the jaw portion 25 is extended relative to the jaw portion 23 such as is shown by Figure l. The jaw I5 is driven on a flange 9 or I and when driven upon a flange, the jaw will appear as shown by Figure 1 with respect to the flange 9 of the rail 5. Owing to the manner in which the jaw I is constructed, the portions 23, 25, when driven on a base flange. will tightly clamp on the upper and lower faces of the base 8. The front edge part 23 of jaw portion 25 is clear of rail 5 when the jaw I5 is clamped to the latter. Depending from the jaw portion 24, and integral with the outer end ll of base I4, is a reinforcing web 28. The sides of the jaw I5 are grooved as at 29 for decreasing the amount of material forming the jaw without impairing the strength of the latter. The jaw I 5, prior to its being driven on the base 8, of. the rail 5, will have the space between edge part 21 of jaw portion 25 and the upper edge or face of jaw portion 23 such that it will require the spreading of jaw portion 25 relative to jaw portion 23 to position the clamp properly on the rail.

The locking arm I6 is of a length to engage the edge and lower face of a flange 9 or ID, for the purpose of locking the jaw on the rail 5. The arm I6 includes a bar-like member 30 which, at its inner end, is integral with the upper portion of the end I8 of the base I4. The member 30 includes a part 3I which extends at an upward inclination with respect to the base I4 and merges into a horizontally disposed angle shaped part 32. The inner end of member 30 is disposed centrally of the upper end of base I4. The member 30'preferably will be of rectangular contour in transverse section and of less width than the jaw I5. The angle shaped part 32 consists of a flat horizontal leg 33 and a vertical leg 34 at the amass? outer end of the leg 33. The upper face 35 of leg 33 constitutes a seat. The leg 34 constitutes a locking or latching member. The upper end of part 31 of the arm I5 merges into the inner end of the leg 33 of the part 32. The latter is disposed at an angle to the part 3|.

When the anchor is to be installed with respect to the rail 5 and it will beassumed it is to have its jaw I5 clamped on the flange 3 of rail base 3, the jaw I5 is arranged on flange 3 in a position whereby the rear end of jaw portion will be at the dot and dash line 36 and the high point of the locking member will bear against the lower face of flange ID at the dot and dash line 31. The outer side face of edge of the jaw portion 24 is then impacted by any suitable instrument for the purpose of setting the jaw I5 relative to flange 3 or III, after which it is driven on the flange by sledging at base end I! or jaw portion 23, to clamping or binding engagement with the rail. As the jaw is driven on the rail,

. the arm I6 will be moved transversely of the bottom of the rail until the locking member or leg 34 snaps over and engages the edge I2 of flange ID, with the latter engaging the seat provided by the leg 33, and at this time the driving action is discontinued whereby the anchor is locked to the rail 5.

Owing'to the manner in which the jaw I5 and locking arm I6 are formed and arranged relatively to the base I4, they will not contact with the tie plate I2a as they are spaced from the latter. Owing tothe tapered form of the base I4 it provides for its inner end hitting the cross tie just before its outer end throwing the first main strength at said inner end where the anchor is on the rail solid and secure.

To remove the anchor, strike a holding blow down on 34 and if needed, hit the jaw on one side to remove it.

The base I4 hits the wooden cross tie I3, but it must have considerable wear before the jaw I5 could hit the tie plate I2". Sometimes tie plates are wider than the wooden cross tie, or the tie plates extend out beyond the cross tie and the jaws of some anchors but the tie plate and the wave motion of the rail when tramc is passing thereover, rocks the cross tie in the ballast and if some ballast is loose. it will work under the cross tie or the tie will work away from the ballast thus making it necessary for track men to retamp the ballast and which entails more or less labor cost. Also the wave motion oi the rail, rubbing the jaw of the anchor band against the tie plate, causes the spikes to be distorted and loosened. Owing to the construction and arrangement of an anchor, in accordance with this invention, tie plate contact, spike loosening and tie rocking are prevented.
