RAIL ANCHOR.

Application filed. December 10, 1920, Serial No. 429,710. Renewed December 29, 1923.

This. invention relates to a rail anchor. It relates particularly to a vertically tiltable rail anchor having jaws to embrace and grip the rail base and thereby hold the rail from creeping.

An object of the invention is to provide an improved rail anchor that will firmly hold the rail against creepage. 7

Another object is to provide a rail anchor which is efiicient, which may be readily manufactured, and which may be readily applied to and removed from a rail base.

Another object is to provide a rail anchor that will grip the rail at both sides of the rail base. V I

Another object is to provide a rail anchor that will be securely held in position on the rail base.

Another object is to provide a rail anchor that will not become laterally displaced from the rail base. Gther objects and advantages will hereinafter appear. I

In accordance with the invention, the anchor has a base body or cross bar extending transversely beneath the rail base. This body or crossbar has a depending leg or foot to engage the rail tie and cause the body member to tilt as the anchor is carried forward by the rail. 7

At one side of the body member are located an upper and a lower jaw to receive and grip the rail base to hold the rail against creepage. v

The base has at its other side a lock to hold the anchor on the rail and keep it from lateral displacement.

1 An anchor which is an embodiment of this invention is shown in the accompanying drawing, in which the views are as follows: I Fig. 1 is a perspective view of the anchor and the lock. I I

Fig. 2 is a side elevation, Fig. 3 is a'plan view, and Fig. 4: is an end elevation.

i "The anchor comprises, in general, a body tor cross-bar 1 having upper and lower jaws 2 and 3 atone end, a pivot 4: at the other end, and a depending leg, 5. The depending leg 5 has a forwardly exitending foot about which the anchor is vertically tilted when the rail creeps and causesthe foot 7 to engage a tie.

When the anchor is in position on the i depending leg 5 engages the tie, as shown in Figs. 2 and 4:.

It the rail tends to creep in the direction of the arrow, as shown in Fig. 4, the foot 7 causes the anchor to tilt vertically and the rear end of the lower jaw 3 and the forward end of the upper jaw 2 to grip the rail base between them and thereby hold the rail from creeping.

The anchor is firmly held in position upon the rail by a lock or clamp 9 which has a jaw 10 and a hook 11.

The jaw 10 bears upon the rail base and the hook 11 embraces the pivot 4.

The pivot 4 and the hook 11 form a pivotal connection between the anchor and the lock to enable the lock to be readily applied. They further hold the anchor and the look from bodily lateral displacement.

In order to apply the lock, the hook is placed on the pivot a and then the jaw is forced inwardly until it bears upon the rail base and holds the anchor firmly in position.

This movement of the lock pulls the jaws 2 and 3 into tight engagement with the rail base.

The anchor base or cross bar is also brought firmly against the rail base by this movement of the look.

This firm engagement of the anchor base against the bottom of the rail base is due to the hook 11 havingits point of engagement with the cross bar arranged forward of the innerend of the jaw. Accordingly, a downward force upon the jaw causes the clamp to tilt forward with this jaw fulcrum- .in at its inner end upon the edge of the rail flange and the outer endv oi the jaw being urged inwardly to keep the lock in position. 4 I j I When the lock is in position, the book 11 pulls upwardly upon the pivot 4 to hold ,the body of they anchor firmly against the bottom of the rail base. v

The lock is kept from turning backward til and becoming displaced by the jaw 10 engaging the rail base flange.

It has been found preferable to make the body of malleable iron and the lock of hardened steel, although, of course, other materials may be used.

iVhen the rail tends to creep, the firm engagement of the anchor with the rail flange carries the anchor with the rail.

The clamp 9, being fulcrumed on the edge of the rail flange, is vertically tilted by this forward movement of the rail.

This causes the jaw 10 to more firmly grip the rail base and also causes the hook 11 to exert a stronger upward pulling action upon the pivot t.

Therefore the anchor becomes more socurely held upon the rail base during creepage of the rail.

Before the cr'eepage of the rail occurs, the weight of the anchor body causes it to fulcrum 011 the rail base about the forward portion of the upper jaw 2. However, when the anchor is carried forward with the rail, the foot 7 will engage the tie and will tilt the anchor vertically.

The rearward portion of the lower aw 3 then engages the rail base and acts as a fulcrum for this tilting action.

It will be apparent, therefore, that this tilting action causes the anchor to more firmly grip the rail base about the fulcrum points on the upper and lower jaws.

Although one specific embodiment of the invention has been set forth, it is obvious that there may be various modifications and adaptations within the purview of the claims.

The invention claimed is:

1. A vertically tiltable rail anchor co1nprising a body to engage a rail base, upper and lower jaws to grip the rail base, and a pivot for applying a lock to said anchor to retain the same in position on the rail base, said jaws being adapted to grip the rail base when said anchor is tilted vertically.

2. A vertically tiltable rail anchor comprising a body to engage a rail base, upper and lower aws to grip the rail base, a pivot for applying a lock to said anchor to retain the same in position on the rail base, said jaws being adapted to grip the rail base when said anchor is tilted vertically, and meansto engage a tie to tilt said anchor vertically.
