YOR-TABLEE ABUTMENT.

Application filed February 29, 1924. Serial No. 636,1 9?

'This invention relates to portable abutment.

It has for its object to provide an improved abutment and more particularly an adjustable abutment adapted to cooperate with a flexible member. Another object 1.8 to provide improved means particularly adapted to cooperate with a rail, and to which a flexible member may be attached. A further object is to provide an improved flexible member abutment in combination with means adapted to cooperate with a rail whereby the same is especially adapted to use in mines or the lilre with the flexible feeding members of mining machines. A

still further object of my invention is to provide such an improved abutment adapted to be mounted upon a rail and so constructed that the greater the pull on the flexible member the greater will be the clamping action thereof on the rail. It is also an object of my invention to provide a device of this type which is extremely simple but yet very effective in its operation.

In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in practice.

In these drawings,-

Fig. 1 is a plan view of my improved de vice mounted upon a rail.

Fig. 2 is a transverse section on line 22 of Fig. 1.

In the illustrative form of my invention 1 have shown the same as comp 'sing a main body portion 1 having flanges :2 strengthening purposes and a dependin and n1- wardly projecting rail web vengn 1g arm 3 from the which as shown in Fig. is spaced inner ed e l of the body member l thus providing a recess 5 into which the rail track portion 6 extends, the forward portion of said body member terminating in a llOliZOltal supporting portion 7 whose lower surface 8 lies in a plane below the lower edge of the track 6. Pivot-ally mounted upon said support 7 as by a bolt and not construction 9 is a fork 10 which has an inwardly extending projection 11 whose outer surface 1:2 forms a cam adapted to engage the web 13 of the rail.

In the operation of my device the i ork 10 will be swung transversely to the member 1 in which position the whole device may be readily placed upon a rail after which a flexible member is positioned in the l 'Ol'lI portion 10 and pulled so as to cause engage merit of the cam 12 with the w-eb.13, it bemg obvious that the greater the pull the greater will be the pinching action upon the web 18 between themembers 3 and 11.

lVhilc I have in this application specifically described one form which my invention may assume in practice, it will be understood that this form ofthesame is shown for purposes of illustration and that the invention may be modified and embodied in variousother forms without departing rrom its spirit or the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. An anchoring device comprising a rigid body portion having at one end a depending and inwardly projecting portion adapted to engage one side of the web of a rail, the other end of said body portion having a sup port, a member pivotally mounted on said support and having oppositely extending lat eral arms, one of which has a camming surface adapted to engage and trictionally grip the other side of the rail web when said member is swung at an angle to the rail, and means carried by the other of said arms to engage a flexible member to be anchored whereby a pull on said flexible member will cause said inwardly projecting portion and said pivotally mounted member to frictionally grip the opposite sides of the rail web.

2. An anchoring device comprising a rigid body portion adapted to partially surround a rail and having at one end a depending and inwardly projecting portion adapted to en gage one side of the web oi the rail, the other end or said body having a lateral projccting support, a member pivotally mounted on said support on a vertical axis and having oppositely extending lateral arms one of which is adapted to engage the other side pf the rail web when said member is swung at an angle to the rail, and means carried by the other of said arms adapted to engage a flexible member to be anchored so that a pull on said flexible member in a direction approximately parallel to the rail will cause. said inwardly projecting portion and said pivotally mounted member to grip the opposite sides of the rail web.

3. An anchoring device comprising a rigid body portion adapted to extend over the Ill) tread of a rail and having at one end a depending and inwardly projecting portion adapted to engage one side of the web of the rail, the other end of said body having a laterally projecting support, a member pivotally mounted on said support on a vertical axis and having oppositely extending arms one of which is provided with a cam surface which is adapted to engage the other side of the rail web when said member is swung at an angle to the rail, and means in cluding a. slotted portion carried by the other of said arms adapted to be connected with a flexible member to be anchored so that a pull on said flexible member will cause said inwardly projecting portion and said cam surface to frictionally'grip the rail, the gripping action increasing as the pull on the flexible member increases. t

4:. An anchoring device comprising a rigid body portion adapted to extend over the oppositely extending arms one of which is provided with a cam urface whlch is adapted to engage and frictionally grip the other side of the rail web, and means including a slotted portion carried by the other of said arms adapted to engage a flexible member to be anchored whereby a pull on said flexible member will tend to swing said cam surface toward the said inwardly projecting portion to frictionally grip the rail and thus anchor the device firmly on the rail.

In testimony whereof I affix my signature.
