Application fild ebruar20, 1926. Seria'1' Noi S9i766.

My invention relates to anchOring devices for rails and more particularlyto the one piece type of anchor in which an upwardly extending arm enters the fishing space and is Wedged in between ti 1ehad and base at one side .of the rail and a shorter upwardly extending arm grips the rail base at the other side of the rail.

One of the Objects of the-inventioh is to provide.a rail anchor of this general type which may be easily'and 'efliciently manufactured, readily brought'toits preIiminarypost tion for application on th e rail; and, When applied to the rail will be in i tsProper opera= tive position, firmly grip boththe head and base of the rail and be so securely held in its operatie position on the.rail that it will not be accidentaliy dis1odged or loosened but may, when desired, be quiekiy remoVed.

, Other objects of the invention are to pro- Vide an anchor of the above gneral character in WhiCh the two uiqwardiy extending arms are, during the application of the anchor to the rail, forced more widely apart thair herst0fore, with corresponding increase in the gripping pressure eXerted on the rail by. the resilienoy Of the anchor; to .proVide maximum gripping pressure upon the head of the rail near thedges of the head:engaging end of the, anehorj and to provide means for indicating the proper anchor on' the rail. i 7 s The invention has for further objects Such other new and improved arrangements and constructions as Will be hereiri 2ifter,described and clainied for carrying ont the above stated objects. V

The invention is illustrated intwo embodiments in the accompanying drawings, whrein {Figure 1 is an elevation, with the rail in section, .of a rail anehor 'construeted in ac- Cordance with nov invention in its operative position on the rail.

In the. drawing A "indicates the,had and B the base.of a railroad rail and C one ofthe cross ties on Which the rail is suppOrted: 'de

anchor is designated by D and is 15rferabi iormed ofa steei bar bent toprovidc a' long arm E, corresponding in 'shape roughi to the cross sect on of the Ordinary fishb ar or fishplate, and a shorter arm' F. The long ar1n 13 is made to fit i nto the fishing spacex v betwecn the head and base of therailand to be wedged therein.and'thesht arr n F is provzded to engage and gripflthe rail base B at the.side of the rail opposite to that engaged by the long arm B. 'The arrns E and F are 'so formed and related to each other. 011 the anchor D that, in the unstresised condition of the anchor, they are doser together than they are in the Stressed condition of the anchor when it is in its applied operativeposition on the rail so that they must be forced aWaythe one from the other as the'anchor D is forced from1ts nitial or prehminary positionshown in Figure 4 ,to its'*final oPerativeyposition shown in Figure 1. Thedotted lines in Figure 1 show theimstressed form and the full fines in.the saine figure the stressed .f0rm of the anchoiD.

The end of the long arrn Ehas its edges rnadc thinner than its media1 portion by forniing dpressions G, preferabiy by forging or pressing the mate'ri al of the bar-cf whiclithe anchor D is made, thus flattening thebar at its edg;es, forming Slight projections.

1n applying anohors of this character to the -rail the longerarm mnstbe broughtto an inclined position in the fishing space' between the head A and base B o f'the'rai1- with the'body undernath the'rail base 18 so that the shQrter arm F may 'be broaght up by I the rail base B at the other side of the rail.

This position is illustrated in Figure 3,and it Will be scn-that the distance which the two arins E and F may be apartin the un stressed condition of the anchor D is determined bythe Contact of one of the upper corners on the longer arm E withthe web of the ra1l and the contact of one of the corners of the shorter armFwith tl1e opposite edge of the rail base B. It is desirable to have the two arrns E and F as close together aspos- 7 sible and still permit the anchor D to Inc r brought to the initial position shoivn in Figure 4 because the extent to which the arme are Spread apart as'the anchor D is forccd from, its initial position to the final operative position det rmines the pressure ex erted by the anchor D upon the rail when in its st'ressed condition in operative' position on the rail. Theformingofthe dpressions G on the upper end of the longer ar1nE With a surface H, below the projectionsI, which willengagethe lower corner ofthe head A of the rail When the anchor is in its preliminary position on the rail as illustrated in Figure 4.

, The fiattening of the upper end of the shorterarm F further increases the distance between the upper corners of the two arrns E and F, Whih determines the ability of the anchor D tobe passed by the rail base B to thepreliminary position shown in Figure 4, and thus, in connection With the depresSionsG at the upper end of the arm E, prov1desa construction 1n' Which the arms E and F are, in the unstressed-condition of the anchor D, doser together 'thanlwould otherwise be possibleand the shorter arm thus may be made. longer than would other wise be possible.

T0 apply the anchor D t0 a rail it'is, after passing the short arm by the rail base as illustrated in Figure -3, moved along the rail towarda tic, in the direction in which the rail tends to creep (indicztted' by the arrow in Figure2), and then brought toth preliminary position shown, in Figure 4 with the surface H on,theflupper end of the longer x arm E engagmg the under. corner of the ra1l head A and thefinner face of the sliorter ar1n F ngaging the upper corner at the 'other side of the rail base B.

f The anchor D is then forcedto the final operative position. on the rail, as shown in Figures land 2, bydriving the longer'arin E into the fishing space between the head A and base B of the rail and by driving the shorter arin F downward by blows of a hamrner indicated by the-arrow in Figure 4. This' forcing of the anchor D into operative posit1on spr iads thearms and F apart, the

shorter aifim F riding on the upper corner of V "the rail base B in the early stages of the move ment,thenthe corner -O riding on the verti- 'cal edge of the rail base until the surface L slips uncer and contacts with the lower cor ner of the rail base B at whichtime the sur face K maycontzrct with the vertical edge of the rail base, as shown in Figure 1, the forging of the surface K has been. such that its plane is Vertical at this tinue. This is not essential. The providing of"the twvo sur faces K and L has the advantage ofindicating unf ailingly to the person applying the anchor its correct operative position on the rail. Thelonger arm E, during this forcing of the anchor D to operative' position, is wedged into the fishing opening betweenthe head A and base B the surface H riding on thei1nder side of the rail head A until the projections I 'come into engagement with the surface of the under side of therail head A. The projections I inthe final operativc :f'

position of the anchor D bear uponthe under surface of the railhead A, asShown in Figures 1 and 2, so that the pressure of the arm E on the head is greatest at the edges of the bar, of Which the anchor D is formed. In the modified form of the anchor D,

Shown in Figure 5, the projections I and the flattenirig G of the inner corners of the upting the end of the bar from 'Which;the an chor Dis formed; and infiattening the end of the shorts! arm F but One beveled surface M is provided; This form of theanchor is applied to'the rail in the manner desciibed' above and in beix1g forced from the initial to the final operative position, showri in,Figur 5, the shorter arm F Will ride on, the upper corner of the rail. during the early inove' ment and then vill rid-with the corner? upon the vertical edge'of the rail base andin the final operative position of the anchor D the lower corner of the rail base B Will be engaged by the inclined surface M. Y

The direction in which the rail tends to creepis indicated the arrow in Figure 2 and it Will radily be understood that, With the longer ar1n Efirmly wedged in between the head A and base Band there held loy the pressure of the'sh0rter armFuponthe rail base B at the other side of the rail, the contact of the anchor D with,the gti C'Wlll prevent the forw21rd 01" cre'eping movement ofthe rail.

iency of the anchor D pcrmits the arm F .to bo drivcn doWn until its npper endreaches the lowcr corner of the rail base B and when this position is reached the anchor D will spring off the rai1. Ihe pressure ofthe ar1n F against the rail base B-isso grcat that the frictionbetween the arm F and the rai] base yvi1l retain'the ar1n F in contact with the rail base B in any of' the successive positions reached in rcmoving the anchor D from the rail and thus permit several bioWs of the bodying 1ny invention, wish it undeistood that changes may be made in the details thereof withoutdeparting from the scope of the invention as defined by the appended claims. r
