UNITED STATES WILLIAM DAL'I'ON, OF SCHENECTADY, NEW YORK.

RAIL FAS'IENER.

Application filed February 2, 1925.

To all 107mm. t may concern.'

Be it known that I, VJILLIAM DaL'roN, a citizen of the United States, and resident of the city and county of Schenectady, State oi New York, have invented a certain new and useful Improvement in Rail Fasteners, of which the following is a speciiication.

',lliis invention relates to means tor fastening rails to ties and consists in a moditication ot the fastening means ol' my prior Patent, No. 1,512,458, dated Getober 21, 19241.

The basic principle and essential feature ot novelty or my invention, which is claimed broadly in my said patent and more specifically in a particular embodiment in the present application, resides in the provision oit ups-tending shoulders or abutments on or secured to the tie on each side ot the rail, the abutment on one side presenting a substantially vertical lace to the edge ot the flange, while the abutment on the other side overliangs the adjacent flange but stands at a greater angle to the horizontal than the top ot the flange, so that, although the rail is securely held to the tie against both lateral and vertical movement, it can be easily removed by simply tilting it on the edge under the overhanging abutment as a lulcrum. rlhe embodiment of this inventive idea, shown and described in my said patent, comprises separate retainer bars, welded or otherwise permanently secured to the tie. .frccording to the presen t invention, the said inventive idea is embodied in a rail chair, interposed between 'the rail and tie and provided with the abutments above described. Two forms of chair are shown in the drawing and will. be described, and obviously still other :forms may be devised which embody the invention. In practice, it usually necessary to insulate the rails `from the ties. since the rails are used as conn duct-ors ol the signal systmn` and I have devised a 'form ot insulator which is adapted for use with my improved rail fastener, and which I believe to merit patent protection. The improvement claimed is hereinafter fully set lorth.

In the accompanyingT drawing:

Figure 1 is a sectional view and Figure 2 a plan view ot the present invention, taken on line 2--2 of igure l, and

Figure 3 is a view, similar' to Figure 1, of a modified form.

Serial No. 6,408.

use a chair which, in the form of Figs. 1-

and 2, consists of a flat plate 3, on which the rail sits and which is rigidly secured to the tie by rivets 4 or, if preferred, by welding, as indicated by the dotted lines Spot welding or bolts may obviously be used, it preferred.

The abutments for the rail llange are punched vup from the plate, that on one side, shown at G, being bent up so as to present a substantially vertical face 7 to` the edge of the flange, while that on the other side, shown at 8, is bent to overlap the adjacent flange, but at such an angle as to leave sufficient space between it and the top of the flange to permit the rail to be removed by tilting it about the flange edge under the overlapping abutment S until the other flange edge comes above the top ot -the abutment G. In other words, the angle which the overlapping portion of the abutment 8 makes with the horizontal is greater than the angle which the top of the ['lange 1l makes with the horizontal. However, the overlapping abutment 8 cont cts (disregarding` the interposed insulation) with the corner ot the rail flange, so that, when the rail is in place, it is securely held from vertical movement relatively to the chair and tie, as well as against lateral movements.

In the form ol Fig. 3, the chair is simplified by simply turning up the ends of a plate 10, secured to the tie as by the coun tersunk bolts shown in dotted lines 11, or by welding 12, one end 1.3 being bent up straight to present the vertical surface 14e to the railllange, and the other lbeing bent up and over so as to overlap the rail ilange in the same manner as the abutment 8.

It is to be noted that, in this case, the,

turned up abutments may extend for the full width of the plate 10, whereas in the form of Figs. l and 2, the abutments do not extend for the full width, inasmuch as they are punched up from the plate and the latter necessarily extends beyond them. It

desired, in either case, two or more abutments may be used on one or both sides, instead of one relatively long abutment.

In order to insulate the rail from the ties, I interpose between it and the chair a pad 16 of fibre, treated canvas, or the like which, in the form of Figs. 1 and 2, is slit at its ends to provide upstanding portions 17 and 1S, interposed between the flange edges and 'the abutment-s 7 and S, respectively, and to provide fiat extensions 19, lying on the plate on each side ofthe said abutments, whereby movement of' the pad transversely to the tie is prevented. In the form of Fig. 3, the pad 2O is simply bent up at its ends, like the `plate 1 0 to fit between the abutment-s 13 and 15, and the flange edges. Ir" desired, this pad 2() may also be wider than the plate and have tongues engaging the ends of the latter to prevent movement of the pad, or it may be engaged by the heads of the bolts 11.

Minor changes in the form of' the chair may be made without departing Jfrom the invention. As an alternative construction, the chair itself may be made of insulating material which, in that case, must be sufficiently stiff and unyielding.

lVhat I claim is:

1. Rail fastening means, comprising a plate adapted to be rigidly secured to the tie beneath the rail, and upst-anding abutments on said plate to engage the-rail flange, the abutment on oncside presenting a substantially vertical face to the adjacent edge of said iange, and the abutment on the other side being bent to overlap the adjacent edge of said flange, said overlapping abutment standing at a greater angle to the horizontal than the top surface of said flange, whereby the rail is securely held against both lateral and vertical movement but can be removed from the tie by tilting it about the flange edge which lies under said overlapping abutment.

21.A rail chair adapted to be rigidly fastened to a tie and comprising a flat portion to be interposed between the rail and tie, an upstanding flange on one side to present a substantially vertical face to the adjacent flange edge, and a bent over flange on the other side to overlap the adjacent flange edge, said overlapping flange standing at a greater angle to the horizontal than the top surface of said flange, whereby the rail securely held against both lateral and vcrtical movement but can be'removed from the tie by tilting it about the iange edge which lies under said overlapping Harige.

Ayr'ail chair adapte'dfto be rigidly :tastened to atie and comprising a plate to be .sedano interposed between the rail and tie, one edge of said plate being turned up to form a vertical abutment 'for one edge of the ri' il flange, and the opposite edge of said plate being turned up and 'bent to overlap the other edge of said flange, said overlapping portion standing at a greater angle to the horizontal than the top surface of said flange, whereby the rail is securely held against both lateral and vertical movement but can be removed from the tie by tilting it about the flange edge which lies under said overlapping portion.

L1. Rail securing means, comprising a chair having a vertical abutment for one rail flange edge and an overlapping abutment for the other rail fiange edge, said overlapping abutment standing at a greater angle to the horizontal than the top of said fiange, to permit the rail to be removed from the chair by tilting it, and an insulating pad adapted to be interposed between the rail and chair and having slit portions bent up to lie between said abutments and the flange edges, flat portions being left to engage the ends of saidvabutments to prevent movement of the pad longitudinally of the rail.

5. rlhe combination with means to removably secure rails to metal ties, comprising a vertical abutment for one edge of the rail flange and an overlapping abutment for the other edge, ot an insulating pad having a flat portion adapted to underlie the rail, and slit to form tongues adapted to fit between said abutments and said flange edges and other tongues adapted to engage the sides of said abutments, whereby said pad is held against movement in any direction.

6. A pad for insulating rails from metal ties which are provided with means for removably securing the rails thereto, said pad comprising a flat portion to underlie the rail with its ends slit to engage said means laterally, the portions between the slits being adapted to be bent up to fit between said means and the rail flange.

7. Rail securing means, comprising a chair made of insulating material and having a vertical abutment for one edge of the rail flange, and an overlapping abutment for the other edge, said overlapping abutment stand-ing at a greater angle to the horizontal than the top of said flange, whereby the rail can be removed from the chair by tilting it about its edge beneath said overlapping abutment as a fulcrum.

In testimony whereof, I have hereunto set my hand and seal, this 28 day of January, 1925. y
