'ANTICBEEPER AND SPREADLESS TIE-PLATE.

Patented nec. 1s, 1917.

Application led November 15, 1916. Serial No.V 131,463. p.

To all whom# may concern.'

Be it known that I, DEMETRrUs KONTO# LAMPROS, a subject of Greece, residing in the city and county of San Francisco, Statel of California, have invented a new and 'useful .Anticreeper and Spreadless Tie- Plate, of whichr the following is a specification in such full and clear terms as vwill enable those skilled iii the art to construct and use the same.

This invention relates to an anti Creeper tie plate and a spreadless tie plate, and its object is for the prevention of creeping and spreading lci the rails upon a railroad track.

The advantages claimed by'thi's invern tion over those now in use is the saw-tooth projections on the underside ofthe plate for rail creeps, so will the ties near thejoint portion, if they do not shear ythe spikes hold` ing the rail downy on the/ties. Under the opposite rail the ties remain in the neutral position, as there is no anchorage of the rail to the plates and ties. Thisv condition will be the same in relation to other rail joints.

The -above has been explained yfor the beneiitof those not familiar with the present situation of rail creeping: .With the anti Creeper tie plate, the objectof this invention, there is the elimination of this Creeping as noted in the four anti Creeper tie plates that are placed opposite the raily joints, therefore forming a rigid construction, and with the angle bars connecting both ends of the rails, these angle bars going into the track bed, and litted snugly against each tie, thereby makes the use of the anti- Creeper tie plates each side of the joint not necessary, and adds to the rigid construction at all the rail joints.

The foregoing and other objects of this invention will hereinafter be more fully described, and claimed and illustrated in the drawings, forming a part of this specification, in which the nsame reference numerals indicate corresponding parts in the differentk views throughout. However, I -am aware that there may be many modifications thereof v Figure 1 is a plan View of a standard gage railroad track, broken away `tor *thev purpose of illustration at the rail oint.

Fig. 2 is a cross section von line 9.-9.

Fig. 1;

Fig. 3 is a'perspe'ctive view corrugatedv lip that prevents 'the'yrail from creeping. Y e

' Fig. 4 is a perspective viewoithe spreadless tie 'pla-te, saine as'the anti Creeper and spreadless tie plate, with the exception ofY slight modification in the construction, andi without `the corrugated lip portion.

Fig. 5Y is an elevation, of the anti/Creeper and spreadless tie plate, showing the 'corrugated lip portion lin the full width vof the plate. e e L y `Fig. 6 is a'modiediorm without` the underside ltooth projections.

Numerals l and 9. indicate both rails yof a railroad track which areheld down by cross tie members, by means ot t1 less tie plates 5, having the usual holes for spiking. It is to be noted that Fig. l'is a plan view at a rail joint, each joint of each rail being opposite the Center of the opposite rail, whichv is vgenerallyl the construe#V tion followed by track layers. Ait theurail joint 6, there are two angle bars called anti Creeper bars, indicated by 7 land S, bolts 9, 10, 11, and 12 bindingthe rail and angle bars together. The spreadless tie plate 5 is used each side of the joints, as the angle bars 7 and 8 tie the rail as the portionsextending into the ground between the't'es prevent moving of the rail. longitudinally. It is to be understood that various spacing may be adopted in placing of both anti Creeper and spreadless tie plates, depending upon the nature of the grade of the track. For example a mountain grade is shown in which the anti Creeper and spreadless tie plate is used for every other tie until the rail joint connections are reached, when the same application of both tie plates is used as noted in Fig. 1 and so on, but it is understood that on a level track, the spacing may be as many ties as preferable for the anti Creeper and spreadless tie plates, in a general case as pne in six or lso ties, according to the judg-` '265 y of the anti' Creeper and spreadless tie plate showing the:

p ne ant-i Creeper i and spreadless tie'plates hand the spread-v only, for the purpose of strengthening that portion of the tie plate, in which the corrugated portion of the lip'QO is under continual stress. The vertical face 16 on said tooth 17 is set slightly beyond the edge 21 -of the recess for receiving the rail, which has the corrugated lip on the upper vportion as alreadyexplained. On the spreadless tie plates the teeth are all the same proportion, and the tooth 2O is also set slightly beyond the shoulder 22 for strengthening that portion thereof. In the anti creeper and spreadless tie plate, ythree holes 23, 24, and 25 are used for spiking, and in the spreadless tie plates four holes are used, namely 26, Q7, 28, and 29. But it is understood that any desired number of holes may be used for spiking the plates on cross ties 3. Thematerial may be of any desired specification, as for example malleable, or alloy steel. rIhis Vapplies to the anticreeper and spreadless tie-plates, and also to the spreadless tie plates, but the latter may -be rolled from sheet steel through roll presses, and cut oftV crosswise of the teeth. The corrugated portion of' the lip 2O may be of any Vshape desirable and hardened, and these teeth are to engage with the flange portion of the rail adjacent thereto when putting the rail into plate and lip recess. In Fig. G is shown a .modified form of the anti creeper tie plate,

in which 32 is the face of the plate that bears on ties, having the usual holes for spiking, and also the usual corrugated lip 35v extending the full width of plate. However, on the oppositeA side of the plate it may be understood that this lip may be of any width desirable on any yof the forms. No

Copies o! lthis patent maybe obtained for teeth projections are used on the underside of the plate in this form.

Having' thus described my invent-ion, what I claim as new and desire to secure by Letters Patent of the United States, modifications being expressly reserved, lis as followsz- Y 1. In an anti-creeper and spreadless tie plate 'or a railway track, comprising aportionY adaptedto be interposed between `the rail. and the ties; Said plate portion to be of the same width as the standard railroad ties; three wedge-shape ribs equally spaced on the underside and extending the full width of the plate; said ribs having` an inclination on the .same side; an extending lip portion ther full width of the plate, the underside of said extending lip having a corrugated portion of V-shaped teeth inclinedv inl the same direction as the flange of the rail, thereby forming a recess in which therail flange is wedged onto the V-shape teeth and into the recess under the lip; and spiking aper? tures through the plate for securing the plate and the rail to the railroad ties.

2. In ,an anti-creeper and spreadless tie plate for a railway track, adapted tov be interposed betweenthe rail and the ties, com-V prising a kflat plate portion having spiking apertures therein for securing the platel and the rail to the ties; three l inclining ribs equally spaced apart on theunderside and the full Width of the plate; an extending lipV portion on the opposite side the full width of the plate; said lipv forming a recess adapt.

able to receive the base flange of a railway rail.; said lip having a corrugated portion. of V-shape teeth on the underside thereof;

and the shoulder of said recess being beyond the vertical side of one of the ribs on the opposite side of the plate. n

In testimony whereof I havehereunto set my hand on this 12th rday of Nevember, A. D. 1917, inthe presence of the two subscribed Witnesses. Y
