Description
W. W. HOLLAND. ANTICREEPING DEVICE.
1,420,703, Patented June 27, 1922.v
VI. HGLLAND, 0F CHICAGO, ILLINOIS.
ANTIGREEPIIIG DEVICE.
Application filed March 3.5, 1922.
To all whom it may concern-.-
Be it known that I, ll innm'ir W. Hot- LAND, a citizen of the United States of America, residing in the city of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Anticreeping Devices, of which the fol.- lowing is a specification.
Anti-creepers embodying cams or similar fastenings in which the increasing dimension of a care which exerts lateral pressure on the rail is brought into play as the rail creeps or tends to creep, tighteni the grip of the anti-creeper as the neeessi y for increased tension is created, are discussed in various prior patents, but they have not come into use to an extent on account of their lack of practical effectiveness because of expense, complication and because of their failure to meet the demands of service, i. e., the varying and excessive stresses which they must resist and vibratory action of the rails which tends to unlock and release the fastening.
The invention relates to an anticreeping device which has been found by practical test to meet the demands.
The drawing illustrates the preferred form of the same.
Figure 1 is a section transverse to the rail;
Figure 2 is a plan.
In the drawing:
The rail 1. rests upon a tie plate 2 constructed and provided with anti-ereepiug features as follows:
The tie plate has a flat rail supporting surface 3 and a vertical shoulder l parallel to the lateral edge 5 of the rail flange 6. The shoulder extends across the plate and has a bearing surface 61 engaging the edge of the rail flange and the shouldered portion is provided with spike holes 7, 8, by which the plate is fastened to the tie. The spike 9 also takes over the edge of the rail flange, the spike 10 being provided merely for the purpose of holding the plate. At the other end of the plate there is a socket 11. In this is seated a cam 12 having a heel 13 integral therewith and seated in the socket, the heel in fact consisting of a pivot or journal of a comparatively large lateral dimension approaching that of the cam to provide an extensive bearing surface of the cam against the tie plate. The
cam is shouldered at 15 to take over the edge Specification of Letters Patent. Ifatzgpfgfl: Jugs 2'2, @322,
Serial No. 5 9-902.
the rail flange and the cam is held in place by lag screw or spike 16, passed through a hole 17 in: the cam and seated in the tie.
ie screw as shown has a square head portion 18 and a circular bearing'surface 19 to engage the cam to provide for rota tion of both members. The square portion is to be engaged by a Wrench to withdraw the screw to remove or replace the cam or to tighten it in operative position. The cam is preferably placed with the increasing dimension turned away from the pull on the rail in the direction of greatest travel, i. e., it is placed on the side toward which such travel takes place.
The simplicity of the structure, its possibilities in the way of cheapness of manufacture and the exceeding firmness and positiveness of its engagement with the rail are apparent.
in operation the plate 2 is placed upon the tie beneath the rail, the shoulder 61 being placed against the rail. Spikes are then driven through the holes 78, the head of one extending over the edge of the rail flange. The heel 13 of the cam having been placed in the socket 11, the cam is turned slightly in the direction of its increasing dimension until the flange of the cam takes over the rail flange. The lag screw or spike 16 is then inserted but not driven down tight, the cam is adjusted by rapping or striking the plane surface 62, rotating the cam cloclswise, referring to the plan view. hen the desired pressure or rigidity of the parts is obtained the lag screw or spike 16 is driven or turned home so as to hold the cam against possible displacement.
Having thus described a preferred form of my invention, I would have it understood that the specifie terms herein are used descriptively rather than in a limiting sense, the scope of the invention being defined in the claims.
What I claim and desire to secure by Letters Patent is:
1. An anti-creeping device consisting of a tie plate having a shoulder at one end with a bearing surface parallel to and enthe lateral edge of the rail, the shouldered portion having an aperture adjacent the bearing surface to receive a spike to hold the plate and take over the edge of the rail, the other end of the plate having a socket, a cam. with a heel integral therewith, the dimensions of the heel approaching that of the cam, the heel resting in the socket and means for securing the cam to the tie in the form of an elongated member with a head passed through the cam into the tie.
2. An anti-creeping device consisting of a tie plate having a shoulder at one end with a bearing surface parallel to and engaging the lateral edge of the rail, the shouldered portion having an aperture adjacent the bearing surface to receive a spike to hold the Plate and take over the edge of the rail, the other end of the plate having a socket, a cam with a heel integral therewith, the
dimensions of the heel approaching that of the cam, the heel resting in the socket and means for securing the cam to the tie in the form of an elongated member with a head passed through the axis of the cam into the tie, the same member having a WOOd engaging thread, the head having a circular surface to engage the cam and a square Wrench engaging portion.
