19 Claims. (01. 233- This invention relates to an improvement in guardrail fasteners, in which a chair for the guard rail is seated. on'a tie plate and supports the guard rail. Under certain circumstances,

8 it is desirable to fasten'the' chair directly to the plate and to use the weight or .the rolling load as "a holding downagent'through the medium.

of the plate rather than the rail.

In' my former Patent Numbers 1,638,739, of

9, I927: 1,639,524, otAugust 16, 1927;

and 1,713,878, of May2'1j1929, the guard rails were shown as fix'ed'to the'chairs, and the latter were provided with means for'underlying ,a portion of the main rail inorder' to hold them down 18 on the tie plate in position to support the guard rail." At the "same'tim'e; the chairs were separable from the guard rail andtieiplate, which is desirable 'to facilitate installation or the removal ofparts. IO In my present invention, this separable rela- Wt 'tion between tie 'plate,guard rail and chair is retained, but provision is made for securing the chair directly to the tie'pl'ate by separable fasteners, which pennit'ready removal of the chair 'or guardrail an'd'whichmakes use of the weight of the rolling load through the medium of'the main railfand tie 'plate to hold the chair and guard railsecurelydown in proper positions.

"Another feature of my present invention is the adjustability of the chair, wherein it may be moved inwardor tilted, "or both, by the use of lateral and vertical shims at the rear of the chair, and arms carried by the chair serve to prevent a complete overturning oithe main tall but allow the main rail to cant within safe limits. In the accompanying drawings:

Fig. 1 is a side elevation of my invention showing themain and guardrails in dotted lines;

Fig. 2 is"a top pla1n view thereof; Fig. 3 is an end elevation of the tie plate and chair' taken from'the left-hand side of Fig. 1;

Fig. 4"is'"a siniilar'view taken from the righthand'side or Fig.1; i .Fig. 5 is a detached perspective view or a nut 451001;; and 1 Figs. Sand 7, Band 9, 10 and 11 are, respec- V tively', detail plan and sectional views of the outer sides of the chair and plate, showing various adjustments of the 'chair by meansof shims.

' The tie plate 1 is of the usual construction, provided with an upturned shoulder 2 atom extreme 'end and with a shoulder 3 spaced inward from" the opposite end in position to receive an edge of the base flange of the main rail 4, which is seated on the tie plate 1.

The usual openings 5 are provided to receive spikes for securing the tie plate to the tie.

The chair is designatedas a whole by the numeral 6 and is provided'with a base portion 7, from which an upstandingjarm 8 extends, upwardlyand inwardly, and. is provided with lateral flanges 9 to fit under and'fenga'ge the head of the guard rail 10,and.which guard rail is held in place by a clip 10. A seat 11 is formed in the chair 6 to receive the base of. the guard rail and support the same; The forward edge of the base a 7. is provided with notches 12 therein to receive, bolts 13, the lower endportionsjor which have flattened sides 14 extending, through elliptical. slots 15 formed in the tie plate 1 toprevent the bolts from turning in these slots. Heads 16 on the lower ends of the bolts engageunder the bottom ofthe tie plate. The bolts 13 are thus upstanding from the tie plate 1 and receive the notches 12 in the base 7 of the chair, andthe upper ends of these bolts 13 have nuts 17 screwed thereon, which nuts are, however, substantially elongated to permit ready connection with a wrench. Washers 18 are interposed. between the undersides of the nuts 17 and the upper surface of the base 7. of the chair, and as shown in Figs. 1 and 2, these washers overhang the edgeof the base flange of the main rail 4 so as to permita slight cant of the main rail but preventinga'complete overturn thereof. The slots 15 for the bolts 13 are approximately at an edge of the main rail base flange.

After the tie plates and main rails have been applied and secured in place, the chair 6 is placed on the plate in the position shown in Fig. 1,

where itabuts against the upstanding shoulder 2 1 and the washers 18 are then applied to the bolts 13 and the nuts 17screwed down into place. The nuts are always accessible for turning, and after a limited period of service, suflicient to reduce any minor inequalities in the bearingsurfaces, the nuts should be again tightened and locked in place by the insertion of locking stips 19 between the sides of the chair 6 and the nuts 17, said locking strips having angularly grooved faces 20 therein for receiving the corners of the nutsand holding the nuts against turning.

The washers 18 are of such size and position as to leave any desired distance between them and the upper side of the main rail base. This prevents any ordinary movement of the main rail, except that of direct lateral pressure, from being transmitted to the chair and, at the same time, prevents the main rail from lifting on the inside beyond a fixed distance. Ordinarily, the main rail the arrows A, B and C, and while the principal.

wear will be against the side of the guard rail head at the upper end of the arm 8 and the flanges 9, due to the pressure of the guard rail thereagainst by the wheel flanges, nevertheless some wear will take place at the point designated by the I arrow D from pressure and movement of the rail" base. As originally applied, the main rail baseis spaced slightly from the chair base '7 at D, which distance may be approximately one-sixteenth of .an inch, but due to wear at this point, this distance will increase, and when it has increased to approximately one-eighth of an inch, the chair 6 may be bodily adjusted laterally; as shown in Figs. 6 and 7, by the insertion of the shim 2l'between the back edge of the chair -6 andthe upstanding shoulder 2 of the tie plate 1, the opposite ends of the shim 21 being bent forwardly about the sides of the chair 6 as shown at 22. As wear increases, subsequent adjustments may be made by the use of other shims, as for instance shown at 23 in Figs. 8 and 9, which not only moves the chair inward toward the main rail but also lifts the rear of" the chair. Further lifting action may be accomplished by the use of shims 24 and '25 in Figs. lo'andll, which provides a considerable range of adjustment forthe. head of the guard rail by a method that is very inexpensive and simple.

The shims may be applied without the removal of any parts and locked in place by bending the free ends, as shown. This method of adjustment causes an inward adjustment of the guard rail head by tilting the chair about a point of contact with the plate at the front of the chair, as well as causing a desired inward shifting movement thereof.
