This invention relates generally to the class of railway equipment, and has more particular reference to an improved means for eflectually fastening railway rails to the ,6 ties in order to insure against accidental displacement thereof. Broadly, the invention aims to provide an improved rail fastening means, by virtue of whichan efiicientand lasti-ng connection is 10 established between the rails and the ties, due to the fact that the spikes are relieved to a great extent of the'lateral strains and stresses ordinarily imparted thereto, thereby preventing loosening of the same in' the tie and, 5 hence,.increasing. their resistance to relative upward movement.

The invention more specifically resides in the provision of a rail fasteningmeans which includes anaperturedshculdered tie plate through which spikes are driven and anchored in the tie, whereby the said apertured shouldered portions function to relieve the spikes, to a marked degree, of the lateral strains and stresses which would-otherwise tend to loosen their anchorage in the ties and to consequently reduce their effective ness to resist upward strains and stresses.

The invention furthermore comprehends in combinationwith shouldered tie plates, cooperatively shaped spikes and spike re-- ceiving: apertures in the said shouldered portions whichein addition to facilitating the laying of the rails, affords an'eifectua l lock against accidental-upward displacement while readily permitting of intentional removal. r

Other-objects of the invention reside in thecomparative simplicity of construction of I the rail fastening means, the'economy with which the same may be produced and the trackage laid by employing said means and the general efliciency derived therefrom.,

With the above recited and other objects in view, reference is had to the following, description and accompanying drawings, in

which'there is exhibited one example or em.- bodiment of the invention, while the claims define the actual scope=ofthe same. Inithe drawings: e H Figure 1' is a fragmentary plan view of a rail secured to a tie by a fastening means constructed in accordance with the in'ven tion.

Referring to-t'he drawings-by characters of reference, A designates the usual' formof wooden tie,.-and B the track rail. fastening means constituting the present in vention includes a tie plate 15 which is ada-ptedto be superimposed on the tie A' and' which is preferably of rectangular configuration and of'a width'exceeding the width-ofthe base flange of the r'ailB; The tie plateis' formed with'shouldered'portions' or bosses 16 spaced apart laterally a distance approxi-' mately equal to 'the width of thebaseflange o'f therail and-adaptedtoreceive therebetweeli said rail base flange, as clearly illustratedin Figures 1 and Qofthe drawings. The shouldered-portions or bosses 1-6, as wellas the'tie plate proper,=are eachprovided witha've'rtical spike-receiving aperture -17','the\ opposite 5 front and rearwalls18 and 1-9-of whichcon verge upwardly. The shouldered portions or l-bOSSeS 16 have the remaining wall 20 hed or depressed s t sam upper end, i

The rail The spikes 22 which constitute an element of the fastening means include a preferably square or non-circular shank corresponding to the size and configuration of the apertures 17 at their uppermost smaller end. The lower end of the spike shank is cut away diagonally as at 2-3, to provide awedge shaped point having a lower entering edge 24 extending from diagonally-opposed corners of the spike shank. This provides a self centering spike which avoids displacement of the tie plate from its correct position when the spike is being driven through the tie plate into the tie. The upper end or head 25 of the spike is provided with oppositely converging forward and rear faces 26 and 27 which correspond to the upwardly converging front and rear walls 18 and 19of the spike receiving aperture 17. The spike head is provided with laterally projecting arms 28, one of which is designed to overlie the rail base flange andthe other of which is received in the notched or depressed portion 21 of the wall 20 of the shouldered portion or base 16. After the spike is driven home to the position illustrated in Figures 2 and 3, a spike locking key 29 having a wedge shaped lower end 30 is driven through the aperture 17 alongside the spike head between one of the converging faces 26 and 27 of the spike head and one of the converging walls 18 and 19 of the spike opening. Adjacent its upper end, the spike locking key 29 is formed with notches 31 in its opposite edges toflfacilitate gripping engagement of a removing tool 1 therewith. Where the rail joints occur and the usual fish plates C are installed, a pair of tie plates 15a are employed, in which one pair of shouldered portions or bosses 16a are spaced apart a suflicient distance in excess of the width of the rail base flange to accommodate the fish plates. as clearly illustrated in Figures 6 and 7 of the drawings.

Where a guard rail D is installed alongside'of a track'rail B, as illustrated in Figures 8 and 9 of the drawings, tie plates 15?) of a greater width areemployed having the shouldered portions or bosses 16b spaced apart laterallyan appropriate distance to acclommodate the'base flanges of both of saidv rai s.

In this instance also, the tie plate 15?) is provided with additional apertures 160 at the transverse center, with which mating notched portions 16d and 16a of the adjacent edges of the base flanges of the rails B and I D register to receive therethrough the retaining spikes 16/.

While there has been illustrated and de. scribed certain preferred embodiments of the invent-ion, it is to be clearly understood that no limitation 'is necessarily made to the precise structural details, and the right is reserved to variations and modifications which properly fall within the scope of the appended claims.
