EDGAR NALDRETT, or EDMONTON, ALBERTA, CANADA.-

BAIL ANCHOR.

Application filed March 27, 1925. Serial No. 18,909.

To all 107mm it may concern:

Be it known that I,

subject of the King of Great Britain,

of the city of Edmonton, in the resident EDGAR NALDner'r, a and Province of Alberta, Canada, have invented certain new and useful Improvements in Rail Anchors, of which specification.

The invention relates the following is the to improvements in rail anchors and an object of the invention is to provide an an chor which will pre vent creeping of the rail under the action of traflic and which vertical movement ing under traflic the fastening spikes loose and the tie and down in the road A further object of provide a rail anchor 0 also allows of a floating of the rail due to bendand by so doing prevents from being heaved from being pounded up bed. the invention is to f comparatively few parts and which can be readily manufactured and which can be readily placed 1n position on the tie and rail.

A further object is to construct the anchor so that any upsetting whilst permitting of the veris prevented tical floating movement action of the rail above intimated.

\Vith the above more important objects in view,

the arrangement and construction of hereinafter more par the invention consists essentially in parts ticularly described,

reference being had to the accompanying drawings, in which:

Fig. 1 is a side view of the anchor applied on the rail and secured to the tie, the rail bein shown in vertical sectlon.

of the parts appear- Fig. 3 is a vertical sectional view at 3-3' Fig. l is a perspective View oi the tie plate.

Fig. 5 is a perspective view 01 the anchor block.

Fig. 6 is an enlarged view of the wedge.

In the drawing like once indicate corresponding eral figures.

The track rail is of presenting a head 1, We

detailed perspective characters of referparts in the sevthe customary type b 2 and base 3. The

anchor which I provide embodies an anchor plate 1, similar pairs of anchor blocks 5 and 6 and four similar wedges 7 The tie plate is substantially rectangular and is placed beneath the rail and sits on the customary tie 8. The. body or that part of the tie plate lying underneath the rail is substantially horizontal and is normally elevated above the tie, tion by having the ends 9 and 10 of the plate inclining outwardly and downwardly at a slight angle as best shown in Figure 1. The ends of the tie plate are fitted with spike holes 11 and 12 and the plate is fastened to the tie by spikes 13 and 14 driven through the spike holes. By making the tie plate arched in this manner, there is a natural tendency under the weight of traffic for the ends of the tie plate to embed themselves in the tie.

The opposite sides of the tie plate are provided with upstanding pairs of opposing similar lugs forming abutments or guides 15, 16, 17 and 18 and these abutments are located outwardly a short distance from the rail base and have their inner faces 19 inclining upwardly and outwardly at a slight angle as shown. In the present instance, these abutments or lugs are formed from the material of the tie plate beingcut therefrom and bent upwardly. The pairs of an chor blocks 5 and 6 are more or-less of a U-shape and each presents upper and lower jaws 20 and 21 connected by an intervening neck 22. The jaws are adapted to span the edges of the rail base and the lower jaws when in place enter the openings or slots indicated at 23 formed in the tie plate; There are. two pairs of wedges 7 and these wedges are gradually tapered and present a large and small end, both the width and thickness of the small end being less than the width and length of the large end.

When the device is to be used, the tie plate is slipped under the rail from the side of the tie and is spiked in place centrally in respect to the rail. The anchor blocks are then put in place by moving them laterally into position and without raising the rail. The small ends of the wedges are then entered between the jaws 2 0 and the rail base being held in such posipermitting of and are driven home by a sledge. The large ends of the wedges are all outermost. After the wedges have been driven home, the inner or thin ends thereof are bent upwardly into a position such as shown in dotted outline in Figure 3 which prevents them from withdrawing.

A rail carried by rail anchors of the type shown is prevented from creeping as the wedges hold the rail base to the anchor blocks and the inner sides of the anchor blocks butt against plate. The rail is also permitted to move or float vertically during'bending under trafiic as it will be obvious that the anchor blocks can move upwardly in relation to the abutments and whilst being maintained tightly fastened to the rail base by the wedges. Theslight inclination given the inner faces of the abutmen-ts is designed to give a slight clearance which permits the rail and anchor blocks secured thereto to rise and fall under the action of traffic. This floating feature prevents the spikes from being loosened and avoids an pounding ofIthe-tie by the rail. The friction surfacebetween the anchor blocks and the abutments is sufiicientto prevent any overturning ofthe rail under all-conditions.

If it should be desired to lock the rail against the floating action above described, it is only necessary .to have the inner faces 19 of the guides 15, 16, 1.7 and 18 inclining upwardly and inwardly in which .case the guides would positively prevent any up movement of the anchor blocks.

lVhilst I have particularly described the floating featuie of the rail, it might be consider'ed however by railroad experts that sucli'is unde i-rable and accordingly I have latterly mentioned the manner in which this floating can be avoided if desired. The article is none the-"less a noveltype of rail anchor regardless of whether'the faces 19 are vertical or-a're pitched slightly upwardly and inwardly.

lVlia't' is I claiiiias my invention is 1. The combination with altra'ck rail and tie, of a tie plate underlying :the rail and secured to the tie and provided with upstanding guides and members anchored to the edges of therail base and slidably engag ing the guides, said guides and memberspermit-ting of a movement of the rail in a vertical direction and preventing any lateral displacement thereof duringsuch movement ment..

2. The combination with a track rail and tie, of a' tie plate underlying the rail and secured to the tie and provided with upstanding guides and, members anchored to the edges oftherail base and slidably engaging th'evguic'les and in contactwith the edges of theplates, said guides and members a movement of thrail the edges of the tie .tie, of

plate within the vertical direction and preventing any lateral displacement thereof during such movement and further preventing any creeping of the rail.

3. The combination with a track rail and tie, of a tie plate underlying the rail and secured to the tie and provided with opposing upstanding guides spaced from the edges of the rail base and intervening members clamped to" the opposite edges of the rail base and slidably engaging the guides and abutting the edges of the tie plate.

4. The combination with a track rail and tie, of a tie plate underlying the rail base and provided with upstanding guides spaced from the edges of the rail base and having slots provided in the edges thereof adjacent the winner sides of the guides, members clamped to the edges of the rail base and extending into the slots and in sliding engagement with the guides.

5. The combination with a track rail and tie, of a tie plate underlying the rail base and spiked to the tie and providedwith upstanding guides spaced from the edges of the rail base and having slots formed in the edges thereof within the guides, anchor locks gripping the edges of the rail'base slidably engaging the guides and extending into, the slots.

6. The combination with a track rail and tie, of a tie plate underlying the rail base and spiked to the tie and provided with opposing upstanding guides spaced from the edges of the rail base and having slots in the edges thereof underlying the rail base and within the guides, pairs of similar anchor blocks anchored to the edges of the rail base and making sliding contact with the guides andhaving the lower ends thereof underlying the rail entering the slots and contacting with the inner sides of' the slots.
